The monitoring terminal monitors wind power, wind speed and wind direction values in real time, regularly returns data and picture information according to a defined return mechanism, and stores relevant video data locally and periodically.
For example, the alarm research trigger management may trigger an alarm if the returned wind power data exceeds a predetermined threshold value (e.g. 6-level wind power) 2 times continuously, control the micro-signal notification signal to push the alarm information, and control the micro-signal notification signal to push the alarm release information if the returned wind power data is below the predetermined threshold value (6-level wind power) 5 times continuously after the triggering. The wind sensor can adopt a high-sensitivity wind sensor device to continuously collect wind data and upload picture (rubbing wind data value) data at regular time (5 minutes/time). The monitoring terminal receives wind speed data of the wind sensor, and the wind speed data is collected once in 5 minutes.
Illustratively, the public number warning information may include: line voltage class, line name, pole position, physical address and two consecutive wind speeds.
The staff can actively select the detection point position through the APP, actively inquire the last acquired wind speed and wind direction information of the specific detection point position, actively review and watch the on-site video of the triggering alarm period, and actively select whether the video is stored or not. The camera of the monitoring terminal adopts a 500-ten-thousand-pixel wide-angle camera with starlight night vision function. The video recording function may be performed upon receiving a photographing instruction. The monitoring terminal can store video capacity of more than 3 days in a high-frequency season.
The monitoring terminal of the embodiment of the invention uploads wind power data and tower information to the cloud platform. The cloud platform displays the alarm information on the power line logic map, and sends the alarm to staff, such as patrol staff and pre-entry clients, through public numbers. The patrol personnel recognize the remote site wind damage condition according to the push information and judge whether the site maintenance is needed, so that the patrol personnel cost is saved more efficiently.
For example, the monitoring terminal may be powered by solar energy. The solar power supply system converts electric energy generated by solar energy into alternating current single-phase 220V and supplies the alternating current single-phase 220V to the monitoring terminal.
The monitoring terminal can also comprise a temperature sensor, a humidity sensor and an air pressure sensor, and detects the temperature, the humidity and the air pressure of the environment. The working environment of the monitoring terminal is-40-70 ℃. The monitoring terminal also has the advantages of small volume, light weight, quick installation, low failure rate, high precision, quick response speed and the like, and is suitable for various monitoring modes of the cloud platform and the client.
