Embodiment 1
[0034] The embodiment is basically as attached figure 1 Shown: a kind of NVR and IPC automatic wireless code connection method, including the following content:
[0035] S1. Start the wireless code pairing function of the NVR, and wait for the code pairing message to be received. The code pairing message is transmitted in an agreed data format, and the code pairing message in the data format is composed of header information and device information ;Header information includes request command type, data length and identification code ID, and device information includes device type and version number;
[0036] S2. The IPC sends the code matching message message through multicast in real time;
[0037] S3, NVR receives the code matching message message in real time, and judges whether the header information length of the code matching message message is consistent with the specified length, if not, the NVR ignores the code matching message message, and does not perform the code ...
Embodiment 2
[0044] The difference between this embodiment and Embodiment 1 is that it also includes dividing the monitoring area where the IPC is set into an important area and a non-important area, and setting up a standby IPC next to the original IPC in the important area, and the original IPC and the standby The IPC understands the same power supply.
[0045] The identification code ID of the standby IPC is the subordinate ID of the identification code ID of the original IPC, if the NVR receives the code message message sent by the original IPC, and has established a connection with the original IPC, then the NVR stores the information between the identification codes. affiliation relationship, the priority of the standby IPC is lower than that of the original IPC, and according to the affiliation of the identification ID, after identifying the standby IPC as a legal device, no connection is made, that is, S4-S7 is not performed; thus, the original IPC and the standby IPC are not connec...
Embodiment 3
[0051] The difference between this embodiment and Embodiment 1 is that if the NVR is disconnected from all connected IPCs, then enable the temporary connection authority of the NVR closest to the NVR as a test NVR, that is, the identification code ID in the NVR Send it to the test NVR, and start all IPCs to send code matching messages. If the detection NVR receives any IPC sending a code matching message with a specific logo, and establishes a connection with the IPC through S3~S7, it is judged that the NVR is faulty , if it detects that the NVR has not received any code matching message sent by any IPC, and has not established a connection with any IPC, then it is judged that the IPC is faulty. By testing the NVR, it can be judged whether the disconnection between the NVR and all connected IPCs occurs on the NVR or the IPC, so that maintenance personnel can repair the NVR or IPC. In addition, a backup server can also be set to store the identification code ID stored in the NV...
