Description

  TECHNICAL FIELD The present invention relates to an energy monitoring system that allows people who promote energy conservation activities (hereinafter referred to as energy conservation activity promoters) to regularly notify and confirm measurement results of energy and promote the practice of recommended energy conservation activities. .

  In recent years, energy conservation activities have been promoted due to increasing environmental awareness. In order to save energy, first of all, it is important to understand the actual energy usage. Therefore, an energy measurement tool (or energy measurement system) that measures various energies according to the target facility has been developed.

  As specific examples of such prior art, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2005-73415, name of invention “Energy Management System”), Patent Document 2 (Japanese Patent Laid-Open No. 2007-280003, name of invention). The invention described in “Energy Conservation Enlightenment System”) is known.

  The energy management system of the prior art described in Patent Document 1 is a system that performs energy management by grasping the energy status of each room in a large number of buildings in a wide site, and the server device with a protocol conversion function is a micro LAN. Collecting data from multiple sensor devices via lines, generating web page data including forms and graphs, and sending WEB page data via LAN lines in response to requests from monitoring devices It is.

  The prior art energy conservation enlightenment system of Patent Document 2 is a system that contributes to the promotion of energy conservation throughout the organization and the energy conservation enlightenment organization. The WEB server with the protocol conversion function performs data processing on the collected measurement data. The data processing server also generates WEB page data including energy-saving enlightenment content by comparing the power consumption and predicted power consumption of each load generated from the measurement data with the target power consumption. The WEB page data can be browsed by the browser of the organization-side terminal device, and energy-saving enlightenment is promoted to the members of the organization so that the energy-saving effect is perceived.

Japanese Patent Laying-Open No. 2005-73415 (FIG. 1) JP 2007-280003 A (FIG. 1)

  At present, there is a problem that the system as in the above prior art is not fully utilized. The reason for this is that only a part of people such as energy managers have operational skills to analyze energy data obtained by the above system and manage which part will lead to energy saving. However, those who have no specialized knowledge tended to not be connected to activities to achieve energy conservation. Promoters of energy conservation activities are not experts such as workers and employees in companies and employees and students in schools, so they can recognize that there is a problem but cannot move forward.

  Even in the energy management system described in Patent Document 1 and the energy-saving enlightenment system described in Patent Document 2, the energy-saving activity promoter can stay at a level where the energy usage status can be easily grasped through the WEB environment. For this reason, energy conservation activity promoters must access and analyze energy data on their own volition, and the energy usage status can be grasped by forgetting it or leaving it unattended because it is cumbersome. Therefore, there was a risk that energy conservation activities would not be promoted as intended.

Furthermore, a device for automatically collecting data from the outside and a means for specifying an address from the outside and passing through the firewall are necessary, and there is a possibility that the communication becomes a complicated system.
In addition, there is a need for separate data collection, automation software that reduces this effort but also increases costs, or a server that accepts data. It was.
In addition, data on energy is an important secret matter, and there has been a request to enhance security so that these data are not leaked to the outside.

  Therefore, the present invention has been made in view of the above-described problems, and its purpose is to provide an energy saving activity promoter with a safe and inexpensive system for not only the actual use of energy but also recommended actions for energy saving. The purpose is to provide an energy monitoring system that ensures notification and promotes energy conservation activities.

  According to the present invention, an energy monitoring system that promotes energy saving activities by notifying the energy saving activity promoter not only about the actual use of energy but also the recommended actions for energy saving with an inexpensive and simple system. Can be provided.

It is a block diagram of the energy monitoring system of the form for implementing this invention. It is explanatory drawing of an energy measuring device. It is an example of a display in the output part screen of a mail terminal.

  Then, the form for implementing this invention is demonstrated below, referring a figure. First, the overall structure of the energy monitoring system 1 will be described with reference to FIG. As shown in FIG. 1, the energy monitoring system 1 includes a propulsion party mail server 10, a propulsion party mail terminal 20, a network 30, a firewall server 40, a measurement target mail server 50, an energy measurement device 60, and a control LAN line 70. The sensor 80 is provided. The energy monitoring system 1 is set in a facility to which an organization that promotes energy saving activities belongs. This energy monitoring system 1 is further divided into a propulsion side and a measurement target side with a network 30 in between.

  For example, if the organization that promotes energy saving activities is a factory unit, the system is installed in the factory. In particular, the sensor 80 is installed on a device that consumes energy such as electrical equipment in a factory building as a measurement target side, and a worker etc. is cited as an energy conservation activity promoter side. It has a terminal 20. If there are a large number of workers to be promoted, a large number of propulsion-side mail terminals 20 are connected.

  For example, if the organization that promotes energy saving activities is an office unit, the system is installed in the office. In particular, a sensor 80 is installed in a device that consumes energy such as air conditioning in the office as a measurement target side, and a clerk or the like is cited as an energy saving activity promoter side. It is to have. If there are a lot of office workers, a large number of propulsion-side mail terminals 20 are connected.

As described above, the energy saving activity promoter is a person who has the authority to operate an apparatus that consumes energy.
Such an energy monitoring system 1 of the present invention can be applied not only to the exemplified office / factory but also to a school / hospital.

  In addition, energy here is electric power amount, temperature, humidity, gas usage-amount, water usage-amount, etc. In addition to selecting only one energy to be monitored, it is possible to monitor a large number of energy by selecting and combining a large number of necessary sensors according to the application, and to perform comprehensive energy management Is possible.

Next, each configuration will be described.
The promoter mail server 10 is communicably connected to the network 30 and functions as an SMTP server or a POP server. How the propellant side mail server 10 operates will be described later.

  The propulsion side mail terminal 20 is connected to the network 30 so as to be communicable. For example, a mail data such as a mobile phone, a PDA (Personal Digital Assistant), or a normal personal computer / laptop is used. It is a terminal that can send and receive. The propulsion person side mail terminal 20 can browse the mail data transmitted from the energy measuring device 60 through the mailer by the energy saving activity promoter. In FIG. 1, one propeller side mail terminal 20 is used. However, as described above, the number is not particularly limited, and a plurality of propulsion side mail terminals 20 are connected to the network. However, in this embodiment, it is assumed that a single propulsion-side mail terminal 20 is used.

  In the network 30, the propulsion-side mail server 10, the propulsion-side mail terminal 20, and the firewall server 40 are communicably connected to each other. The network 30 includes various lines such as a normal Internet line and a dedicated line owned by a communication company. Further, it includes an existing network such as a private LAN line built in the building. When the propulsion side mail terminal 20 is a mobile phone or PDA, it is connected to the network 30 via a mobile communication line (not shown). Further, when the propulsion side mail terminal 20 is a personal computer, it is connected to the network 30 via a wireless LAN or a communication line.

  For example, if the factory is assumed to be connected to the firewall server 40, which will be described later, the network 30 is connected only by a local LAN line, or is connected by a line combining a local LAN line or a normal public line. You can also.

  In such a network 30, mail data can be transmitted and received between the propulsion-side mail server 10 and the propulsion-side mail terminal 20. In addition, mail data can be transmitted and received between the propulsion-side mail server 10 and the measurement target-side mail server 50. The type of line is not particularly limited as long as these transmissions and receptions are possible.

  The firewall server 40 is communicably connected to the network 30, reveals a part of the internal network as viewed from the network 30, and makes the remaining internal network private. The public internal network is called DMZ (DeMilitarized Zone). When the network 30 includes a public network such as the Internet, such a firewall server 40 is interposed to reduce the risk of virus intrusion. The energy measuring device 60 is not connected from the outside via the network 30 due to the presence of the firewall server 40. Further, since the mail format is adopted, it is easy to pass through the firewall server 40 from the inside. With this configuration, an energy consuming device connected to an internal device such as the energy measuring device 60 or the sensor 80 or the sensor 80 (the sensor enables operation of a device that consumes energy such as a switch) from the outside to the device that consumes energy. Security is increased by preventing access.

  The measurement target side mail server 50 is connected to the firewall server 40 and functions as an SMTP server. The measurement target side mail server 50 is arranged in the DMZ and set as a public server. How the measurement target side mail server 50 operates will be described later.

  The energy measuring device 60 functions to create mail data from the energy data about the energy acquired through the sensor 80 and transmit the mail data to the propulsion side mail terminal 20, and is connected to the firewall server 40 and kept private. Is set. Therefore, the energy measuring device 60 cannot be accessed from the outside. The energy measuring device 60 is mounted with only the minimum necessary functions so as to be relatively inexpensive and small. These energy measuring devices 60 are installed in the vicinity of a device that consumes energy such as facilities such as loads and feeders in factories and buildings. In FIG. 1, it is assumed that one energy measuring device 60 is installed. However, the number of energy measuring devices 60 is not particularly limited, and a plurality of energy measuring devices 60 can be installed.

Such an energy measuring device 60 includes a CPU 61, a network module 62, a memory 63, and a power source 64 as shown in FIG. In addition, a connector for communicably connecting to the control LAN line 70 and the firewall server 40 is also provided.
As will be described later, the CPU 61 functions as a series of means for generating mail data from a series of energy data collected from the sensor 80 side and transmitting the mail data to the propulsion side mail terminal 20 via the network 30. Hereinafter, the energy measuring device 60 itself will be described as functioning as these means.

  The network module 62 has a function of converting a control LAN protocol for the control LAN line 70 and a network protocol for the network 30. If the network 30 is a local LAN line, the network protocol is, for example, a LAN protocol (for example, Ethernet (registered trademark)) in the physical layer and data link layer, and a protocol conversion so as to be TCP / IP in the transport layer and network layer. To do. Similarly, if the network 30 is a public line, the control LAN protocol for the control LAN line 70 and the network protocol for the network 10 are converted. The network protocol is at least a normal TCP / IP communication protocol. In this way, various conversions are possible.

The memory 63 temporarily stores data. In addition, an address for the propulsion side mail terminal 20 accessible by the system administrator is registered in advance, and the CPU 61 designates the address read from the memory 63 to generate mail data. In addition, text data (described later) about recommended actions of energy consuming devices operated by the energy saving activity promoter having this address and the actual usage of energy is also registered in the memory 63, which will be described later. E-mail data with content that matches the device that consumes energy is generated.
The power source 64 supplies direct current power to each part in the energy measuring device 60.

  The energy measuring device 60 also functions as a WEB server, and has a function as an internal database for registering data for publishing WEB content and a content creation server for creating WEB data as WEB content using this data. . For example, the energy measuring device 60 registers the energy data transmitted from the sensor 80 in an internal database, stores and manages the energy data in a batch, generates web content about energy saving using these energy data, and includes this content WEB data is limitedly disclosed within the internal network that is not disclosed by the firewall server 40. The WEB data is disclosed as HTML data or XML data. A terminal connected to the private internal network can read the WEB content by reading the WEB data and using the browser of the terminal. The energy measuring device 60 is like this.

  The control LAN line 70 is connected to the energy measuring device 60. The control LAN line 30 is a micro LAN (one-wire bus system developed by Dallas Semiconductor) line and can be connected by bus, so that a large number of sensors 80 can be connected.

  The sensor 80 is connected to the control LAN line 70. A plurality of (for example, 16) sensors 80 are bus-connected to the control LAN line 70, and each sensor 80 is installed in a facility. An ID number is assigned to each of the plurality of sensors 80 in advance, and by sending a command including the ID number from the energy measuring device 60 at a constant cycle (for example, a cycle of 3 minutes), the sensor 80 can receive a corresponding feeder or The load energy data is transmitted to the energy measuring device 60 via the control LAN line 70 by the micro LAN. The sensor 80 measures a physical phenomenon to be measured at predetermined time intervals and outputs energy data. The energy measuring device 60 and the sensor 80 communicate with each other via a control LAN line 70 using a micro LAN. Note that only one sensor 80 may be provided. Further, the sensor 80 may also have a switch function so that simple operations such as ON / OFF and adjustment of a device that consumes energy may be performed.

Next, actual operation of the energy monitoring system 1 will be described.
In this energy monitoring system 1, the energy measuring device 60 itself creates mail data and is registered in advance as in a so-called mail magazine without adopting an access method of data download upon request from the propulsion side mail terminal 20. The form of automatically delivering mail to the proponent side mail terminal 20 is adopted.

  As this mail data, normal text data is used. Further, as will be described later, in this mail system, if image data that cannot be posted in the mail text is converted into a file and attached to the mail data, the attached image data also passes through the firewall server 40. Sent to. Further, mail data including a photo / image in the mail data body as HTML mail data is surely transmitted to the propellant side mail terminal 20 because it passes through the firewall server 40. Furthermore, in the mail method such as this so-called mail magazine, it is possible to simultaneously deliver mail to a large number of specific proponent side mail terminals 20, so that the number of energy conservation activity promoters can be increased, and further promotion of energy conservation activities can be achieved. I can expect.

  First, the energy measuring device 60 functions as a collecting unit that collects energy data measured and output by the sensor 80 for energy. The collected energy data is stored in the memory 63.

Subsequently, the energy measuring device 60 functions as a first determination unit that determines whether or not a predetermined period has elapsed. When it is determined that the predetermined period has elapsed, it functions as a mail data generation unit to be described later, and starts generating mail data.
If mail data is transmitted regularly in this way, you will regularly participate in energy-saving activities, and you can prevent forgetting.

In addition to the first determination unit, the energy measuring device 60 determines whether the energy data collected by the collection unit exceeds the past maximum value data, or whether the energy data is the past minimum value data. You may make it provide the 2nd judgment means to judge. When it is determined that it exceeds or falls, the mail data generation means described later is caused to start generating mail data.
In this way, if mail data is sent immediately at the time of an abnormality exceeding the maximum value or falling below the minimum value, the abnormality will be recognized immediately.

In addition to the first and second determining means, the energy measuring device 60 determines whether the energy data collected by the collecting means exceeds preset threshold data or the energy data is preset. You may make it provide the 3rd judgment means which judges whether it is less than threshold value data. When it is determined that it exceeds or falls, the mail data generation means described later is caused to start generating mail data.
In this way, if mail data is sent immediately in the event of an abnormality that exceeds or falls below a threshold value that is considered abnormal, the abnormality is immediately recognized.

In addition to the first, second, and third determining means, the energy measuring device 60 compares the energy data collected by the collecting means with past energy data such as one year ago or one day ago. Thus, fourth determination means for determining whether or not the difference is large may be provided. When it is determined that the difference is large, the mail data generation means to be described later is started to generate mail data.
In this way, if mail data is sent immediately at the time of an abnormality that is significantly different from the past value such as one year ago, the abnormality will be recognized immediately.

Subsequently, the energy measuring device 60 functions as a mail data generating unit that generates mail data about the monitoring contents based on the energy data collected by the collecting unit.
For example, when a predetermined period of time has elapsed by the first determination means and the energy data represents a normal value, the text “No abnormality”, text data such as numerical values and symbols registered in advance in the memory 63 is selected. It is to do.
Mail data having such text data as a body or mail data having text data as an attached file is generated.

Further, for example, when the second determination means determines that the energy data exceeds the past maximum value data, the “energy data becomes XX and the past maximum value data is registered in advance in the memory 63 for each mail address. XX exceeded. △△ Please reduce the output of the device ”, select the text data of numerical values and symbols, and the energy data measured in XX, and the maximum value in XX It is to fit the data. Such text data is also optimized for each energy saving activity promoter, that is, for each mail address, and such text data is registered in the memory 63 for each energy saving activity promoter, that is, for each address.
Mail data having such text data as a body or mail data having text data as an attached file is generated.
Note that the mail data and text data set by the third and fourth determination means are generated in the same manner except that text data of the purpose of determination is prepared, and redundant description is omitted. .

  The energy measuring device 60 functions as a transmission unit that transmits the mail data generated by the mail data generation unit to the propulsion-side mail server 10. When the propulsion side mail terminal 20 is designated as an address, mail data is first stored in the measurement target mail server 50 through the firewall server 40. The firewall server 40 permits access from the energy measuring device 60 to the measurement target mail server 50 and transmission of mail data, and mail data is normally transmitted.

  The measurement target mail server 50 functions as an SMTP server, and transmits it to the propulsion side mail server 10 via the firewall server 40 and the network 30. When the promoter side mail terminal 20 accesses the promoter side mail server 10, the promoter side mail server 10 functions as a POP server, and transmits mail data to the promoter side mail terminal 20. The energy conservation activity promoter confirms the energy status and, if there is an instruction, controls the energy equipment based on the instruction to practice the energy conservation activity. As described above, since different instructions are included for each energy saving activity promoter, it is only necessary to adjust a device that consumes energy according to this instruction, and the energy monitoring system 1 that promotes highly effective energy saving activities is provided.

  According to such an energy monitoring system 1, it is possible to confirm the state of energy at the time of mail check. In addition, since the topic items are arranged and received by the self-diagnosis function, the labor of checking the entire data is saved. In addition, it is possible to grasp trends in the use of energy consuming devices that are not noticed by energy conservation activity promoters. In particular, energy conservation activities by a large number of energy conservation activity promoters can be expected, and an improvement in energy conservation effects can be expected.

  In addition, when the energy measuring device 60 functions as the WEB server 60, the WEB data having the same content as the content transmitted with the mail data or the more detailed content as the WEB content is generated and the WEB content can be browsed. good. For example, an energy conservation activity promoter who has been notified of an abnormality by e-mail at the e-mail terminal 20 on the propulsion side requests more detailed information and can access the dedicated terminal and view it in real time on a browser. is there.

  For example, if the WEB content (for example, the content shown in FIG. 3) based on the latest analysis data can be browsed by shortening the energy data readout interval (for example, every 3 minutes to 1 minute), the apparatus that consumes approximate energy You can explore the last trend. Further, after the energy saving activity promoter adjusts the device that consumes energy, if the WEB content can be browsed, the adjustment is performed and the energy saving effect of the device that consumes the energy that is currently in operation can be confirmed. In this way, the waste of energy of the organization can be easily understood visually, and each person belonging to the organization can recognize that energy saving activities are necessary. By making it possible to check not only email but also this WEB content, more detailed energy saving activities can be expected. The energy monitoring system 1 is like this.

Next, an improved form of the energy monitoring system 1 will be described. In this form, the graph data is added by the mail data generation means. Accordingly, since the components other than the mail data generating unit function in the same manner, the description of the mail data generating unit will be described in detail without redundant description.
Specifically, as the mail data generation means, first, the energy measuring device 60 selects to select text data that is a combination of sentences, numerical values, or symbols prepared in advance based on the collected energy data collected by the collecting means. Functions as a means.

  For example, when it is determined by the second determination means that the energy data exceeds the past maximum value data, “energy data becomes XX and past maximum value data XX registered in advance in the memory 63 for each mail address ×× △△ Please reduce the output of the device ”, select text data of numerical values and symbols, measure the energy data in XX, and the maximum value data in XX It is to apply.

  Subsequently, the energy measuring device 60 functions as an image data generating unit that generates image data representing a graph generated based on the energy data collected by the collecting unit. For example, graph data is generated by graphing energy data. Specifically, it is graph data in a display example as shown in FIG.

  Subsequently, the energy measuring device 60 functions as a combination generation unit that generates mail data about the monitoring contents by combining the text data selected by the selection unit and the image data generated by the image data generation unit. In this case, by using HTML mail data, it is also possible to use mail data in which both image data and text data are texts.

  Subsequently, the energy measuring device 60 functions as a transmission unit that transmits the mail data generated by the mail data generation unit to the propulsion side mail server. Since transmission is the same as the previous description, a duplicate description is omitted.

  The present embodiment has been described above. To add graph data on energy, it is expected that energy conservation activity promoters will be able to confirm the trend of energy monitored by graphs, grasp the situation securely, and promote further energy conservation activities . Even in this case, since the mail format is adopted, it is easy to pass through the firewall server 40 from the inside.

Next, another improved form of the energy monitoring system 1 will be described. In this form, the mail data generating means attaches the measurement file data to the mail body. Accordingly, since the components other than the mail data generating unit function in the same manner, the description of the mail data generating unit will be described in detail without redundant description.
Specifically, as the mail data generation means, first, the energy measuring device 60 selects to select text data that is a combination of sentences, numerical values, or symbols prepared in advance based on the collected energy data collected by the collecting means. Functions as a means.

  For example, when it is determined by the second determination means that the energy data exceeds the past maximum value data, “energy data becomes XX and past maximum value data XX registered in advance in the memory 63 for each mail address ×× △△ Please reduce the output of the device ”, select text data of numerical values and symbols, measure the energy data in XX, and the maximum value data in XX It is to apply.

  Subsequently, the energy measuring device 60 functions as an image data generating unit that generates image data representing a graph generated based on the energy data collected by the collecting unit. For example, graph data is generated by graphing energy data. Specifically, it is graph data in a display example as shown in FIG.

  Subsequently, the energy measurement device 60 functions as a measurement file data generation unit that includes the image data generated by the image data generation unit and generates measurement file data that is file data for explaining measurement based on the energy data. For example, data generated by spreadsheet software. Moreover, you may transmit the mail data which uses the measurement file data which combined image data and text data as an attached file. Further, by using HTML mail data, it is also possible to use mail data having both image data and text data as a body.

  Subsequently, the energy measuring device 60 further measures the measurement file data generating means for the body data of the monitoring content generated by combining the text data selected by the text data selecting means and a part of the file data extracted from the measurement file data. It functions as a combination generation means for generating mail data with the measurement file data generated in step 1 attached.

  Subsequently, the energy measuring device 60 functions as a transmission unit that transmits the mail data generated by the mail data generation unit to the propulsion side mail server. Since transmission is the same as the previous description, a duplicate description is omitted.

  The present embodiment has been described above. Measurement file data including energy-related graph data is attached to the body of the email and sent so that energy conservation activity promoters can check the trend of energy monitored by more detailed graphs and measurement data to ensure the situation. It is expected that we will strive to promote further energy conservation activities. Even in this case, since the mail format is adopted, it is easy to pass through the firewall server 40 from the inside.

  Next, the energy monitoring system 1 according to the embodiment will be described. In the first embodiment, the sensor 80 is specifically an electric energy sensor. The following description will be made assuming that the power amount sensor 80 is used. In this case, it is possible to individually measure the current and voltage of a feeder to which a load (not shown) is connected, and the energy data is output at every predetermined minute time interval.

  The electric energy sensor 80 includes a current sensor such as a clamp-type CT and a voltage sensor, and detects the current and voltage of the feeder and load. For this reason, it is possible to measure the effective value, instantaneous power, electric energy, and integrated electric energy of these currents and voltages. An ID number is assigned to each of the plurality of power amount sensors 80 in advance, and by sending a command including the ID number from the energy measuring device 60 at a constant cycle (for example, a cycle of 3 minutes), the power amount sensor 80 is The corresponding feeder and load energy data are transmitted to the energy measuring device 60 via the control LAN line 70.

Subsequently, the energy measuring device 60 functions as a collecting unit that collects energy data measured and output by the electric energy sensor 80 for voltage and current. The collected energy data is stored in the memory 63.
Further, based on the voltage and current detected by the power amount sensor 80 from the load or feeder, the power consumption of each feeder in the building and a plurality of loads (not shown) connected to the feeder is calculated. Is done. Or based on the voltage and electric current which the electric energy sensor 80 of the electrical room (not shown) detected from the feeder, the electric energy used of the whole building will be calculated. This calculated power consumption is also energy data. In this way, energy data of the whole tissue and each part is collected by the electric energy sensor 80.

  Subsequently, the energy measuring device 60 functions as a first determination unit that determines whether or not a predetermined period has elapsed. When it is determined that the predetermined period has elapsed, the mail data generation means described later is caused to start generating mail data.

  In addition to the first determination means, the energy measuring device 60 determines whether or not the instantaneous power consumption (power peak value) that is energy data collected by the collection means exceeds the past maximum value data, Alternatively, a second determination unit may be provided for determining whether or not the instantaneous power consumption (power peak value) that is energy data is past minimum value data. When it is determined that it exceeds or falls, the mail data generation means described later is caused to start generating mail data.

  In addition to the first and second determination means, the energy measuring device 60 is preliminarily configured to use a power amount or an instantaneous power consumption (power peak value) that is energy data collected by the collecting means. Whether it exceeds the set threshold data, or whether the amount of power used as energy data or the instantaneous power consumption (peak value of power) is below the preset threshold data You may make it provide the 3rd judgment means to judge. When it is determined that it exceeds or falls, the mail data generation means described later is caused to start generating mail data.

In addition to the first, second, and third determining means, the energy measuring device 60 uses the amount of power as the amount of power that is energy data collected by the collecting means as the amount of power that is past energy data. You may make it provide the judgment means which judges whether a difference is large compared with the usage-amount. When it is determined that the difference is large, the mail data generation means to be described later is started to generate mail data.
When these second, third, and fourth determination means determine, it is an abnormal time, and it is predicted what kind of problem will occur in the abnormal time.

  The energy measuring device 60 functions as a calculation unit that calculates electric power based on the collected energy data collected by the collecting unit and sequentially accumulates the electric power to generate the power consumption of the facility.

The energy measuring device 60 functions as a selection unit that selects text data prepared in advance based on the power calculated by the calculation unit and the amount of power used.
For example, as an alarm,
(1) When it is determined that the amount of power used exceeds the contracted capacity, (2) When it is determined that the amount of power used deviates from the threshold value that is a preset warning area, etc. The contents are combined with a prepared text and a numerical value to make a mail alert text.

In addition, as a result of energy diagnosis,
(1) If it is determined by the second determination means that the instantaneous power consumption (power peak value) has updated the maximum / minimum records so far,
(2) When it is determined by the third determining means that the usage amount or the instantaneous usage amount of power (peak value of power) is out of the threshold value,
(3) If it is determined by the fourth judging means that the amount used is significantly less or more than the same period last year,
Send a uniform email regardless of urgency. As a result, the energy conservation activity promoter notices that the measured values are different from usual.

For example, when it is determined by the second determining means (2) that the instantaneous power consumption (power peak value) generated from the energy data exceeds the past maximum value data, it is stored in the memory 63 for each mail address. Pre-registered text “Numerical power consumption (peak value of power) became XX, which exceeded past maximum value data XX. The text data of the symbol is selected, the measured energy data is applied to XX, and the maximum value data is applied to XX. Such text data is also optimized for each energy conservation activity promoter, that is, for each address, and such text data is registered in the large number of memories 63 for each energy conservation activity promoter, that is, for each address.
Mail data having such text data as a body or mail data having text data as an attached file is generated.

  The energy measuring device 60 is an analysis graph comparing the power consumption with respect to the power calculated by the calculation means and the target power calculated in advance based on the capacity and operating time of each facility based on the power consumption. It functions as image data generating means for generating image data to be represented. The image data looks like the graph data shown in FIG.

  The energy measuring device 60 functions as a combination generation unit that generates mail data about the monitoring contents by combining the text data selected by the text data selection unit and the image data generated by the image data generation unit. It becomes like the body data combining the graph data and text data of FIG. For example, the text data can be mail data in which the image data and text data are both text by using HTML mail data combining the graph data and text data of FIG.

  The energy measuring device 60 functions as a transmission unit that transmits the mail data generated by the mail data generation unit to the propulsion-side mail server 10. The processing after the transmission is the same as the above description, and a duplicate description is omitted.

  In addition, the energy measurement device 60 generates WEB data having the same content as the content transmitted by the mail data or more detailed content based on the energy data, and the WEB server 60 can view the WEB content. It is also good.

  For example, an energy conservation activity promoter who has been notified of anomalies by email data at the proponent side email terminal 20 can request more detailed information and view it in real time on a browser of a terminal connected to a private internal network That's it. For example, shorten the energy data read interval (for example, every 3 minutes to 1 minute), generate power from the current and voltage of this energy data, and generate power consumption of the equipment by sequentially integrating this power Next, it functions as an analysis unit that generates analysis graph data in which the amount of power used is compared with a target power amount calculated in advance based on the capacity and operating time of the facility. Generates graph data using bar graphs and line graphs for the predicted power consumption based on the current power consumption, visual data on energy saving effects, etc., including the power consumption for each facility, such as load or feeder, To do.

  If it is possible to browse WEB content based on the latest analysis data, it is possible to search for a trend immediately before a device that consumes approximate energy. Further, after the energy saving activity promoter adjusts the device that consumes energy, if the WEB content can be browsed, the adjustment is performed and the energy saving effect of the device that consumes the energy that is currently in operation can be confirmed. In this way, the wasteful use of electricity in the organization can be easily grasped visually, and each person belonging to the organization can recognize that energy saving activities are necessary. The energy monitoring system 1 is like this.

Prevent forgetting and contribute to energy saving.
