Description
Technical Field
The invention belongs to the technical field of video monitoring, and particularly relates to a method for accessing IPC based on a physical port of network access equipment and NVR.
Background
Video monitoring is an important component of a safety precaution system, and is widely applied to many occasions due to intuition, accuracy, timeliness and rich information content. In recent years, with the rapid development of computers, networks, image processing and transmission technologies, the popularization trend of video monitoring is more and more obvious, and the IP video monitoring technology is more and more adopted to replace the traditional analog video monitoring technology.
In the prior art, the application of accessing the IPC through a Network Video Recorder (NVR) is more and more common, the NVR can automatically acquire the IP address of the IPC and store the IP address into IPC channel information, then the NVR automatically accesses and manages the IPC through an ONVIF protocol, and a user can subsequently modify the configuration parameters of the IPC such as video coding, video storage plans and the like and operate monitoring services.
However, after the original IPC fault is replaced, the user starts the automatic search function, and finds that the new device obtains the device information of the new device through the ONVIF, if the device serial number is not in the IPC channel record of which the NVR already exists, an IPC channel record is added, and if the device serial number already exists, the IP address in the IPC channel record of which the original device serial number is located is refreshed. However, because the device serial number of the new replaced device is not consistent with the original IPC, the NVR is considered as a new IPC access, and an IPC record is added instead of updating the original IPC channel record. At this time, if the stored video of the original IPC needs to be preserved, the channel record of the original IPC cannot be deleted, and a new video storage plan needs to be manually specified for the newly added IPC channel. If other configuration information such as the code of the original IPC is to be reserved, the original IPC channel record needs to be manually modified to be consistent with the original IPC, two channel records of the original fault IPC and the newly added IPC exist in the NVR, two video storage plans exist, and the services of live operation, playback and the like of a user are inconvenient. When the NVR storage space is not vacant, only the storage video which is still required to be reserved by the original fault IPC can be deleted, and the residual storage space can be allocated to the replaced new IPC, so that the video in the planned retention period can not be reserved.
Meanwhile, many users develop a lot of use habits from the era of analog video monitoring, if the access of the network camera IPC is expected to be associated with the physical port of the switch, and the manual configuration process is reduced as much as possible in the access process. However, in the prior art, when an IPC fault is replaced, the operation is very inconvenient, and the user experience is poor.

Detailed Description
The technical solutions of the present invention are further described in detail below with reference to the drawings and examples, which should not be construed as limiting the present invention.
The application of accessing IPC through a network video recorder NVR is more and more common, the NVR can automatically acquire the IP address of the IPC and store the IP address into an IPC channel record, then the NVR automatically accesses and manages the IPC through an ONVIF protocol, and a user can subsequently modify the configuration parameters of IPC such as video coding, video storage plan and the like and operate monitoring services. In a small video monitoring network, NVR and IPC are directly accessed to a router of a user, and the router has a DHCP function; in a video monitoring network with more IPCs, a plurality of network access devices are usually required to access the IPCs, both the network access devices and NVRs are accessed to a router, and the router is provided with a DHCP or accessed to a DHCP server.
The invention does not limit the network access equipment accessed by the IPC, and for a small video monitoring network, the network access equipment directly accessed by the IPC is the router, and the physical port information is the physical port information of the router accessed by the IPC. And when the network access device to which the IPC is directly accessed is a switch, the physical port information is the physical port information of the switch to which the IPC is accessed. In the following embodiments, a switch is taken as a network access device to which IPC directly accesses, and the description is made based on physical port information of the switch.
As shown in FIG. 1, the method for accessing IPC based on the physical port of the network access equipment of the present invention comprises the following steps:
s1, the network access device inserts the physical port information of the network access device accessed by the IPC in the received first message, and forwards the first message;
s2, after receiving the first message, NVR analyzes the physical port information, then searches for an IPC channel record according to the physical port information, if the IPC channel record corresponding to the physical port information already exists, inherits the IPC channel record as the IPC channel record of the IPC, otherwise, creates a new channel record of the IPC corresponding to the physical port information.
The method for accessing IPC based on the physical port of the network access equipment is described by two embodiments as follows:
in the first embodiment, the NVR supports IPC access in a dual-port networking mode, and the first message includes a DHCP request message and a DHCP reply message.
When the NVR supports double network ports, one network port of the NVR is connected to the switch where the IPC is located, and the other network port of the NVR is connected to the router where the DHCPServer is located. As shown in fig. 1, IPCs 1 and IPCs 2 are connected to a switch, a portal 1 of NVR1 is connected to the switch, the switch enables a DHCP Relay, and a portal 2 of NVR is connected to a router where a DHCP Server is located, and the router may be a built-in or external DHCP Server.
When a new IPC is accessed to a physical port of a switch, the IPC acquires an IP address through a DHCP Server; when the IPC sends a DHCP Request broadcast message, the switch receives the message and then adds the switch physical port information containing IPC access to the option 82 of the Request message, unicast sending is carried out to a DHCP Server, the message is forwarded to the DHCP Server through an NVR, the DHCP Server allocates IP for the IPC, unicast replies DHCP ACK, the ACK message is forwarded to the switch accessed by the IPC through the NVR, the NVR monitors the DHCP interaction message on a network card chip, and the switch physical port used by the IPC and the IP address allocated to the IPC by the DHCP Server are obtained from the DHCP ACK message; and the NVR inquires the added IPC channel record information, if the IPC channel of the physical port of the switch does not exist, an IPC channel record is newly added, the IPC channel record comprises the information of the physical port, the IP address and the like of the switch, and the IPC is automatically connected and managed through an ONVIF protocol.
When the IPC fault needs to be replaced, the new IPC is accessed to the switch physical port of the original IPC, and the process that the new IPC obtains the IP address through the DHCP is consistent with the process that the original IPC obtains the IP address through the DHCP; the DHCP Server may allocate a new IP, when the DHCP ACK response message of the DHCP Server is heard by the NVR, the physical port and IP address information of the switch are obtained, the NVR inquires the added IPC channel record information, if the IPC channel record information of the switch port exists, the new IP address is updated to the IPC channel record, the original IPC channel configuration information is inherited, and the newly accessed IPC is managed through the new IP address.
As shown in fig. 2, the switch configures a virtual interface address of 192.168.0.254, configures a next hop address of the default static route of 192.168.0.1, and starts a DHCP Relay to designate a DHCP Server of 192.168.1.254. The NVR supports double network ports, the address of the network port 1 is 192.168.0.1, the address of the network port 2 is configured to be 192.168.1.2, and the gateway of the network port 2 is set to be 192.168.1.1.
The access procedure of IPC is as follows, taking IPC1 as an example for description:
IPC1 accesses switch physical port 1, IPC1 initiates a DHCP request. The switch receives a DHCP Request broadcast message sent by IPC1 from port 1, adds option 82, and identifies the position information of IPC1 in sub-option 1 of option 82, namely, receives a two-layer port number and a vlan number of the DHCP message: node identification + frame number/Ethernet port type/slot number/subslot/port number + vlan ID, such as switch1_0/eth/1/0/1_ vlan 1.
The switch forwards the option 82 added message unicast to a DHCP Server through the NVR dual-port, the DHCPServer allocates information such as an IP address, a mask, a gateway and the like for the IPC1, and responds to a DHCP ACK unicast message to a DHCP relay device, namely the switch, wherein the message comprises DHCP network configuration information and option 82 information, for example, the address allocated to the IPC1 is 192.168.0.2/24, and the gateway is 192.168.0.1.
Because all messages of the DHCP Relay and the DHCP Server are forwarded between the network port 1 and the network port 2 of the NVR, the NVR can monitor the DHCP messages, and when discovering that the DHCP Server responds to the DHCP ACK messages of the DHCP Relay, the messages can acquire information such as the IP address of the IPC, the physical port number of the access switch and the like.
Therefore, the physical port number information of the switch is analyzed from the DHCP ACK message, and the IP address allocated by the DHCP to the IPC can be obtained from the DHCP ACK message, so that all required information can be obtained at one time. In addition, when the DHCP Request is not responded, if the switch physical port number information is analyzed from the DHCP Request message, but the DHCP does not respond, the NVR cannot normally manage the replaced IPC, so that the switch physical port number information is analyzed from the DHCP ACK message in the embodiment, and the condition that the DHCP Request is not responded and fails is prevented.
The DHCP Relay of the switch then transmits the mode of converting the unicast message into the broadcast message to the IPC1, and the IPC1 acquires the information of IP address, mask, gateway and the like to configure the network parameters.
And the NVR automatically tries to initiate connection to the obtained IPC IP address by using an ONVIF protocol, and if the connection is successful, an IPC channel is added and contains the obtained IPC IP address and the physical port number information of the switch. The user can configure parameters such as coding information, video storage plans and the like for the IPC channel, and operate monitoring services such as live performance, playback and the like.
The IPC channel information recorded in NVR is shown in Table 1:
TABLE 1
When IPC1 can not be used due to failure, the user purchases a new IPC for replacement, and if IPC1 ' is assumed, the user accesses IPC1 ' to physical port 1 of the switch, and the IPC1 ' access process is as follows:
after the IPC1 'is powered on, a DHCP process is initiated, and like the access process of the IPC1, assuming that the IP address allocated to the IPC 1' by the DHCP is 192.168.0.3, after the DHCP ACK message of the DHCP Server is intercepted by the NVR, the switch physical port number and the IP address information therein are analyzed, and then whether a channel of the switch physical port number information already exists in the existing IPC channel is searched, if so, the IP address of the IPC channel is updated to be 192.168.0.3, as shown in table 2:
TABLE 2
NVR adopts 192.168.0.3 IP address to connect and manage IPC 1' through ONVIF protocol, and keeps continuity of services such as video storage of the original IPC channel.
In the second embodiment, the first message is an ONVIF response message for IPC access in the NVR single-port networking mode.
When the NVR only has one single network port, the network port of the NVR is connected to the switch where the IPC is located, and the switch is connected with the router where the DHCP Server is located. As shown in fig. 3, IPCs 3 and IPCs 4 are connected to a switch, the network port of NVR1 is connected to the switch, and the switch is also connected to a router where a DHCP Server is located, or the switch itself is built-in or externally connected with the DHCP Server.
In this embodiment, the switch can monitor the ONVIF protocol message between the IPC and the NVR, modify the ONVIF to obtain the corresponding IPC message of the device information message, and add the physical port information of the switch to which the IPC is accessed; after receiving the ONVIF message, the NVR acquires switch physical port information in the ONVIF message, inquires added IPC channel record information, if the IPC channel record information of the switch physical port does not exist, the IPC channel record information is newly added, and the IPC channel record information comprises an IP address of IPC, an access switch physical port and other channel information; if the IPC channel record information of the switch port exists, the equipment is considered to be replaced due to failure, and the new IP address is updated into the IPC channel record.
The specific access procedure of IPC is as follows, taking IPC3 as an example for description:
after the IPC3 is accessed, network information such as IP addresses and the like is obtained and configured through a DHCP, and the NVR obtains access URL and IP address information of the IPC3 through the ONVIF existing automatic discovery technology. The NVR acquires the switch port information accessed by the IPC3, the ONVIF equipment information acquisition method is used for sending an equipment information acquisition message to the IPC3, and the IPC3 responds to the NVR with the ONVIF equipment information, wherein the contents are as follows:
<tds:GetDeviceInformationResponse><tds:Manufacturer>UNIVIEW</td s:Manufacturer><tds:Model>IPC1</tds:Model><tds:FirmwareVersion>I PC-B0002LJ01</tds:FirmwareVersion><tds:SerialNumber>210235T0AC314B000075</tds:SerialNumber><tds:HardwareId>IPC1</tds:HardwareI d></tds:GetDeviceInformationResponse>
after receiving the ONVIF response message for acquiring the device information from the port 1, the switch analyzes and adds the switch physical port information accessed by the IPC3, and then forwards the information to the NVR, wherein the added information is in italic as follows.
<tds:GetDeviceInformationResponse><tds:Manufacturer>UNIVIEW</td s:Manufacturer><tds:Model>IPC1</tds:Model><tds:FirmwareVersion>I PC-B0002LJ01</tds:FirmwareVersion><tds:SerialNumber>210235T0AC314B000075</tds:SerialNumber><tds:HardwareId>IPC1_switch1_0/eth/1/0/1_vlan1</tds:HardwareId></tds:GetDeviceInformationResponse>
The NVR acquires the IP address of the IPC3 and the physical port information of the switch from the response message, and if an IPC channel without the physical port information of the switch is found, the IPC channel is added; if the IPC channel of the physical port of the switch already exists, the IP address is refreshed into the IPC channel record, and the IPC is accessed and managed through the new IP.
The second embodiment is different from the first embodiment in that: the switch can analyze the ONVIF equipment information acquisition and response message and add IPC accessed switch physical port information in the ONVIF equipment information acquisition and response message; NVR does not need to monitor DHCP message; the NVR may parse the physical port information in the ONVIF device discovery response message sent by the switch.
After the NVR obtains the physical port information corresponding to the IPC, the subsequent operation is the same as that in the first embodiment, if there is no IPC channel record information of the physical port of the switch, the IPC channel record information is newly added, and the IPC channel record information includes the IP address of the IPC, the physical port of the access switch, and other channel information; if the IPC channel record information of the switch port exists, the equipment is considered to be replaced due to failure, the new IP address is updated into the IPC channel record, and the IPC channel record is inherited as the IPC channel record of the IPC.
In summary, the two embodiments of the present invention respectively describe: under the condition that the NVR can receive the DHCP ACK message, analyzing the DHCP ACK message to obtain physical port information; and when the NVR cannot receive the DHCP ACK message, the physical port information is acquired from the ONVIF response message. It is to be understood that, in the case of the first embodiment, the method of the second embodiment may also be adopted to obtain the physical port information from the ONVIF response message, so as to implement IPC access based on the physical port of the network access device.
As shown in fig. 4, based on the above method, the NVR of physical port access IPC based on network access device of the present invention includes:
the analysis module is used for analyzing the physical port information of the IPC accessed to the network access equipment from the received first message;
and the channel record maintenance module is used for searching the IPC channel record according to the physical port information analyzed by the analysis module, inheriting the IPC channel record as the IPC channel record of the IPC if the IPC channel record corresponding to the physical port information exists, and otherwise, newly establishing a channel record of the IPC corresponding to the physical port information.
It should be noted that the first message includes a DHCP request message and a DHCP response message, the network access device inserts physical port information of the IPC-accessed network access device into the DHCP request message, the DHCP server sends the DHCP response message after receiving the DHCP request message, the DHCP response message includes the IPC-accessed physical port information, and the parsing module parses the physical port information of the IPC-accessed network access device from the DHCP response message. Or the first message is an ONVIF response message from the IPC, the NVR sends an ONVIF acquisition device information message, the IPC sends an ONVIF response message after receiving the ONVIF acquisition device information message, the network access device inserts physical port information accessed by the IPC into the ONVIF response message, and the analysis module analyzes the physical port information accessed by the IPC to the network access device from the ONVIF response message.
The above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and those skilled in the art can make various corresponding changes and modifications according to the present invention without departing from the spirit and the essence of the present invention, but these corresponding changes and modifications should fall within the protection scope of the appended claims.
