The lightning arrester is an electric appliance which is used for protecting electric equipment from being damaged by high transient overvoltage during lightning stroke, limiting follow current time and normally limiting follow current amplitude.
After the lightning arrester is used for a long time, the lightning arrester is easy to suffer from performance aging caused by being wetted, which is a problem of damage. Therefore, the performance state of the arrester needs to be monitored regularly to ensure the normal operation of the arrester.
The existing system for monitoring the operation data of the lightning arrester in real time generally collects the real-time operation data of the lightning arrester firstly, and then feeds the real-time operation data back to a background server in a wireless communication mode to be processed so as to analyze the performance state of the lightning arrester, thereby ensuring the normal operation of the lightning arrester. However, the lightning arrester operation data real-time monitoring system often enables the communication module to be in a working state all the time, and energy consumption is increased invisibly and needs to be improved.
Disclosure of Invention
Based on this, in order to solve the problem that the existing real-time monitoring system for the operation data of the lightning arrester causes the communication module to be always in a working state and invisibly increases energy consumption, the invention provides an online monitoring system and method for the lightning arrester based on wireless communication, and the specific technical scheme is as follows:
the utility model provides an arrester on-line monitoring system based on wireless communication, includes collection module, communication module, processing module and backend server, collection module is used for gathering the operational data of arrester. The processing module comprises a processing unit and a wake-up unit.

The awakening unit is used for awakening the communication module according to the awakening instruction and sending the packed running data to the communication module.
The communication module is used for transmitting the packed running data to the background server in a wireless communication mode.
Although the lightning arrester is aged due to the influence of external objective factors, the operation data of the lightning arrester in a normal state is usually changed slowly and maintained within a certain voltage value range. That is, the operational data of the arrester in the normal state generally has no monitoring value.
When the operation data at a certain time point is beyond the preset range value, the performance of the lightning arrester is abnormal. At the moment, the operation data of the preset time width before and after a certain time point is the operation data related to the abnormal performance problem of the lightning arrester.

Although the lightning arrester is aged due to the influence of external objective factors, the operation data of the lightning arrester in a normal state is usually changed slowly and maintained within a certain voltage value range. That is, the operational data of the arrester in the normal state generally has no monitoring value.
When the operation data at a certain time point is beyond the preset range value, the performance of the lightning arrester is abnormal.

In conclusion, the lightning arrester online monitoring system solves the problem that the existing lightning arrester operation data real-time monitoring system enables the communication module to be in a working state all the time, and energy consumption is increased invisibly, and can effectively monitor the performance state of the lightning arrester.

Particularly, the online lightning arrester monitoring system further comprises an SR trigger, the awakening unit is electrically connected with a set end of the SR trigger, and the dormancy unit is electrically connected with a reset end of the SR trigger. At any moment, only one of the wake-up instruction and the sleep instruction is effective, that is, either the set end of the SR flip-flop is at a high level or the reset end of the SR flip-flop is at a high level. And the output end of the SR trigger is electrically connected with the enabling end or the power supply input end of the communication module.
Therefore, through the awakening unit and the dormancy unit, when the performance state of the arrester is abnormal, the communication module is awakened so as to transmit the packaged arrester operation data to the background server through the communication module, and the performance state of the arrester is monitored and analyzed by the background server according to the operation data of the arrester.

And S3, waking up the communication module according to the wake-up instruction and sending the packed operation data to the communication module.
