Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Referring to fig. 1, an NVR and IPC auto-pairing method includes the following steps:
step 1: NVR starts a wireless code matching function;
the NVR has an independent wireless code matching opening interface, the interface is convenient for operating personnel to conveniently control the interface, when the NVR opens the wireless code matching, a plurality of IPC wireless code matching requests can be received, and meanwhile, the IPC which finally and effectively analyzes the ciphertext and the distance range between the IPC and the IPC can be controlled according to the signal intensity limiting information.
Step 2: the unpaired IPC sends out a wireless code matching request in a broadcasting mode;
in the practical application process, the paired IPC does not send a wireless code pairing request, unless the paired IPC is reset and restarted or the like, the wireless code pairing request is sent in a broadcast mode, and any NVR can be received (as long as the NVR is within the wireless signal coverage range of the IPC). It will be appreciated that the wireless pair code request should contain the identity flag of the corresponding IPC, etc. to facilitate that the NVR can then unicast the information to the IPC.
And step 3: NVR receives the wireless code matching request and sends a ciphertext containing SSID information, password information and signal strength limiting information to IPC in a unicast mode;
any NVR receives the wireless code matching request, a ciphertext is sent according to the request, SSID information and password information in the ciphertext are local area network information of the NVR, and signal strength limiting information refers to the minimum value of signal strength which is received by an IPC (inter-process control) end and allows code matching to the NVR; the advantage of this arrangement is that as long as the IPC is located near the NVR, the signal generated by the NVR will appear strongest at the IPC, based on this logic, it is possible to improve the pairing efficiency and avoid mis-matching binding by the NVR at a remote location during the production of the mating, and the distance range of the pairing centered on the NVR can be more flexibly shown due to signal limitation.
And 4, step 4: the IPC receives and analyzes the ciphertext, and judges whether the signal intensity of the corresponding NVR is higher than the threshold value of the signal intensity limiting information or not according to the signal intensity limiting information; if yes, performing step 5; otherwise, performing the step 2;
and 5: the IPC stops sending the wireless code matching request, configures the SSID, the password and the random IP address in the same network segment with the NVR according to the SSID information and the password information, and sends the SSID, the password and the like to the NVR to establish wireless connection.
In the embodiment, the IPC determines the NVR to be accessed by judging the signal strength of the NVR, and the signal strength limit information of ciphertext interaction in the pairing process can be selected on the NVR wireless pairing-code opening interface. By establishing the connection with the IPC by the method, the code matching range of a single wireless video monitoring suit can be limited when a plurality of sets of wireless video monitoring suits are matched, and the error matching of the code matching of the plurality of sets of wireless video monitoring suits during production is avoided; and the cost of manual participation can be reduced in large-scale IPC layout use (especially under the condition that IPC or NVR is replaced in the later period after installation is finished), and the networking difficulty is reduced.
