DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on illustrated embodiments. FIG. 1 is a system schematic diagram showing a basic embodiment of the present invention. In the figure, reference numeral 1 denotes an entrance door provided with a lock as an object to be controlled, and is provided at an appropriate place inside the entrance door 1 (not shown).
An electronic circuit including a pager is incorporated, and the electronic circuit controls an operation mechanism that opens and closes the door lock, so that the door lock opens and closes. Items equipped with locks as controlled objects are not limited to entrance doors, doors at entrances,
It includes general opening / closing means which can be opened / closed at the opening of a building such as a window, a house, an office, etc. The operating mechanism refers to a mechanism that operates the electronic circuit to open and close the lock, but the lock itself may include an operating mechanism. Further, reference numeral 2 denotes a pager base station for calling the pager, and a pager attached to the door 1 via a communication terminal such as a public telephone 3 or a portable telephone (or PHS) 4 held by each user as necessary. Call. Since the mechanism of the pager used in this system is already well known as a pager system, a detailed description thereof will be omitted. However, a unique call number is assigned to the pager in advance, and the public telephone 3 or the mobile telephone is used. Dialing the call number of the target pager from, the call number is transmitted to the pager base station 2, and the corresponding pager is called via the wireless communication medium. Also, as a conventional pager, when a call is made to the pager, a message composed of a simple character can be added and transmitted as desired, or the pager is preset in a memory in the pager. There are some which have a function of specifying and displaying any one of a plurality of stored and stored messages.

Therefore, if such a pager is diverted and applied to the present invention, a system can be constructed at low cost without designing a dedicated pager again. For example, when calling a pager attached to a door (lock) for opening and closing a lock, one of a number, a code, and a message, which are recorded in advance and corresponding to opening or closing of the lock, is designated,
Or send it directly from the telephone. The electronic circuit attached to the door or the like that receives this signal identifies what the sent message is, and opens and closes the door lock based on the result. The need to lock (close) the door lock, that is, to remotely control the locking is as described above.
Regarding unlocking, for example, when an acquaintance or friend visits an absence home, there are many cases where the user wants to open the door and guide the user to the house as necessary, and then wait for him to return home. This is often the case if the visitor is a close relative, such as a close relative. By the way, when unlocking is performed by the present system, a slight defect of the system by a third party is a serious defect of the system. For example, if the pager calling radio wave is intercepted by a third party and the ID information included in the radio wave is known, the door unlocking is performed by calling the pager using the ID information. It becomes possible. In order to prevent such inconvenience, a means for enhancing the security function is added in this embodiment.

S, Activate the mobile phone and press the required push button 24 while pressing the back speaker opening 25 of the key against the mouthpiece.
Then, the signal is transmitted to the clock unit 32 and I through the control unit 31.
The data is transmitted to the D memory unit 33 and the DTMF generation unit 35, and operates in the following order. (1) The time signal at that time is supplied to the ID memory 33. (2) The ID memory 33 stores a plurality of pieces of ID information using time information as an address. The ID information corresponding to the input time is read out and supplied to the DTMF generator 35. (3) At the same time, a signal read from the pager call number memory 34 in which the call number of the called party is stored is also supplied to the DTMF generator 35. (4) The DTMF generator 35 supplies a DTMF signal to the speaker 36 based on the signals input in a predetermined order. (5) The speaker 36 actually converts the DTMF electric signal into an audio signal and outputs it. (6) This sound reaches the telephone converter via the mouthpiece of the telephone and further to the pager of the entrance door.

Next, FIG. 3 is a block diagram showing the configuration of an electronic circuit provided on the door side. The electronic circuit on the door side for receiving radio waves transmitted from the outside in this manner is transmitted through the antenna 41 via radio waves. A receiver 42 for receiving and demodulating the call number, a memory 43 for storing the call number of the own station, and a number comparator 44 for detecting a match between the call number included in the demodulated signal and the memorized call number of the own station. Pager, a clock section 45 for generating a time signal, an ID memory 46 storing a plurality of ID information, and comparing the ID information called from the ID memory 46 with the ID information included in the output signal from the pager. ID comparator 47, a controller 48 for outputting various control signals based on the output from the comparator 47, and lock control by the controller output. The child lock (operating mechanism) 49, are those that contain. Although the above description has been made by dividing the blocks for the sake of convenience, it goes without saying that it may be configured in software by a control circuit by a CPU. The operation will be described in this configuration.
When the demodulated signal includes a call number that matches the call number of the own station, the ID added to the call number and transmitted
An information signal is supplied to the ID comparator 47. As described above, since the ID information that sequentially changes in response to time (time) is selectively transmitted as described above, the clock circuit described above corresponds to the time change ID information in the receiving side circuit. 45, and a large number of IDs stored in the ID memory 46 according to a predetermined procedure at each time.
Predetermined ID information is read out of the information and supplied to the ID comparator 47. Accordingly, different ID information is supplied to the ID comparator over time as time passes. If the ID information matches the ID information supplied from the pager, the ID comparator further outputs the demodulated output of the pager. Is supplied to the controller 48 to indicate either the locking or unlocking. The controller 48 reads this signal and controls the electronic lock 49. This electronic lock is a combination of the operating mechanism described in the claims and a lock.

[0010] As described above, if at least the ID information for unlocking the door or the like is changed and transmitted every moment, and the receiving side is configured to cope with this, the effect of preventing theft of a third party can be exhibited. it can. The change of the ID information is 2
The effect will be further enhanced if the time is changed every 5 minutes in units of 4 hours, or if the order is changed so that the order is changed every day. Of course, some kind of confidentiality or encryption is also effective. If only the door is locked by this system, no special damage will be caused even if the third party steals the door, so the above-mentioned means may not be necessary in some cases. The keys with an auto dialer shown in FIGS. 2A and 2B may be a portable auto dialer having only the function of the electronic circuit unit, or the electronic circuit unit may be a PHS or portable telephone. It may be incorporated in a telephone. That is, the PHS and the mobile phone have a memory for storing an auto dialer function and a calling number,
Since many devices have a CD display or the like, it would be convenient to realize the same function. By the way, as a lock for the entrance door or the like, a lock that is electrically opened and closed recently called an electronic lock is commercially available. This is provided with an input button such as a numeric keypad, and is unlocked when a specific ID such as a number or a character is input. Therefore, the present invention can be realized by using such an electronic lock, and the description of the structure of the lock itself is omitted. Various operation modes of the door lock system using the present invention are conceivable. Basically, as described above, if the user subscribes to the pager service for each individual and attaches the pager built-in door lock device to the target door, the pager can be called up as required and the required operation can be performed.

FIG. 4 is a system schematic diagram showing another example of the operation service using the present invention. This example is a system example in which a door lock remote control service is provided to a desired person and advertisement information from a sponsor is simultaneously delivered to a subscriber. That is, as described above, a person who desires a door lock remote control service attaches the pager built-in door lock device to the target door and attaches or fits a display such as an LCD. As is well known, a pager receiver is useful as a terminal device for receiving various information, and is therefore convenient for delivering desired information in real time. Therefore, as shown in FIG. 4, an advertisement is solicited from a department store, a supermarket, a shopping mall group, a private store, or the like at the information distribution center 50 that performs the service, and the advertisement information is distributed as desired. Although such advertisements are provided in newspaper insert advertisements and flyers, advertisement distribution using a pager receiver can be reported in real time, and the advertisement effect will be remarkable.
For example, it is good to notify the same content as a daily specialty product advertisement like a conventional flyer, but if the sold-out information of the specialty product is distributed, it will be a service for the customer. In the past, merchandise advertisements conducted by stores were based on the prospect of increasing the number of customers by feeding a small amount of eye-catching products,
Such palliative means no longer work, and reporting the sale of featured goods as they are will increase customer confidence. It is also effective to prepare a substitute eyeball product and to notify that effect, in order to increase sales. In particular, fresh food products such as fish and vegetables are often unclear as to which items arrive cheaply in the morning of the day, so they are often excluded from targets to be notified in advance by flyers, etc., according to the present invention, Utilizing the characteristics of the real-time notification, it is possible to notify the arrival information of fresh foods. Such information distribution can be reported locally, for example, by CATV or the like. However, construction costs such as cable laying increase, whereas the present invention is extremely inexpensive.
If you provide an information distribution service in addition to the door lock service, it is two birds per stone.
