There are four warning levels, namely safety, warning, danger, and accident, and the corresponding colors are: white, yellow, red, and orange. The color will be displayed on the warning light 3.

[0062] When the alert level is safe, that is, the person is 1 meter away from the initial warning line, the warning light 3 will be white, and some tips on safe and energy-saving electricity use can be broadcast when necessary; When the alert level is warning, that is, the person is within 1M of the initial warning line, the warning light 3 will turn yellow, and the device will issue a voice message such as "Please leave, danger ahead" to drive away; When the alert level is dangerous, if someone breaks into the photovoltaic area, the warning light 3 will turn red, and the device will make a voice call to ask the other party to return along the original route, and strongly inform the dangers and consequences of the intrusion; When the alert level is accident, when someone has an accident in the photovoltaic area, the warning light 3 will be yellow, and the person will be asked to stay where he is, and the relevant power lines nearby will be shut down in time to ensure safety and power outage, and the backend will be notified to handle it as soon as possible. When the alert level is at the highest level, it is considered that someone has an accident in the photovoltaic area, and the backend administrator will send a shutdown signal to cut off the power lines near the photovoltaic safety warning device.

[0063] S3, the thermal imaging infrared sensing module 4 and the camera 7 respectively obtain the human body position information near the photovoltaic safety warning device and the image information near the photovoltaic safety warning device in real time and transmit them to the main control module.

[0064] S4, compare the acquired human body position information with the set warning distance. When the human body position information falls into the warning distance of the corresponding warning level, start the sound and light content corresponding to the warning level, and the main control module uses the voice playback module 2 and the warning light 3 to broadcast the sound and light content.
