[0025] The power module supplies power for the master module, the multi-element weather sensor, and the image monitoring module.

[0026] The tension sensor module is powered separately.

[0027] The master module allocates power supply periods according to monitoring requirements; the master module communicates with the multi-element weather sensor through RS-485, communicates with the image module through IIC, communicates with the monitoring platform through 4G, and communicates with the tension sensor through a wireless protocol; the master module controls the linkage of the tension sensor, the multi-element weather sensor, and the image monitoring module.

[0028] The tension sensor includes a sensor body, a power module, and a communication module.

[0029] The power module uses a photovoltaic panel and a lithium iron phosphate rechargeable battery to provide the energy required for the tension sensor to work.

[0031] The communication module

[0032] The multi-element weather monitoring module includes a housing assembly, a wind direction and speed sensor, a rain sensor, and a light radiation sensor.

[0033] When the environmental weather reaches the weather conditions that cause the camera in the image monitoring module to fog, the master module turns on the defogging mode (opens the lens heating and turns on the windshield wiper), ensuring the reliability of the image monitoring module.

If there is a hidden danger, the picture with hidden danger is uploaded to the monitoring platform and an alarm is given to let the monitoring personnel check and handle. If there is no hidden danger, the picture with meteorological information is uploaded to the monitoring platform for storage. If it is confirmed that it is an abnormal weather of icing, the tension sensor data information is collected and compared with the correct value to calculate the conductor icing value at that time. If the data is confirmed to exceed the set threshold value, the master control reports to the platform and an alarm is given.
