[0078] When encountering bad weather, the target tower can use the metal rod 15 to control the large photovoltaic panel 5 to be placed close to the ground; the bad weather includes: heavy rain and typhoon.

[0079] Specifically, the model of the large photovoltaic panel 5 of this embodiment is 72HL4-BDV. The photovoltaic panel is produced by the N-type TOPCon process and has lower LID / LeTID attenuation and better weak light performance; the double-sided power generation gain increases with the back light, significantly reducing the LCOE; the overall component has passed the certification of the maximum front test static load of 5400Pa and the maximum back test static load of 2400Pa; the attenuation probability caused by the PID phenomenon is minimized through battery production technology optimization and material control. It adopts a 72*2 arrangement scheme, with a total of 144 solar cells, with a size of 2278*1134*30mm, suitable for placement in open locations; its maximum power can reach an average of 600W, which can meet the energy supplement of airport flash lights.

[0080] Optionally, a large solar photovoltaic panel 5 is set in a suitable area near the flashlight (the principle is that the flashlight pole does not block the light and is outside the flashlight's light-emitting angle) to generate electricity for a large lithium-ion battery 4. The large lithium-ion battery 4 provides DC power to the flashlight through a converter. The lamp pole adopts an aviation warning yellow fragile pole, and the connection between the pole body and the base adopts easy-to-break parts. Communication is controlled by ZigBee or 6loWPAN network technology, and the 2.4GHz frequency band with the least impact on the electromagnetic environment of the flight zone is adopted. The entire system does not require lighting station control equipment and power cables for power supply, and is green, environmentally friendly, and remotely intelligently controlled.

[0081] Preferably, the capacity of large photovoltaic panels 5 and large lithium-ion batteries 4 is calculated as follows: Assuming that the rated power of the flashing lights at an airport in a certain region is 100VA, the flashing lights have a total of three levels of dimming, calculated according to the highest level of three-level dimming at night, the power consumption of the light source electrical appliances is negligible, the lights are on for 6 hours a day, and according to the worst monthly peak sunshine hours in the region of 4.5 hours, the required battery panels are 6h×100W×1.5 (charging factor) / 4.5h / 0.9 (efficiency) / 0.8 (redundancy factor)≈300W. The battery capacity is calculated to meet the needs of three consecutive rainy days. Taking into account appropriate redundancy, the appropriate capacity is about 180AH. That is to say, at this airport, only 300W of battery panels and 180AH of batteries are needed, which can provide the manufacturer's flashing lights with the highest three-level dimming for 6 hours a day and ensure continuous power supply for three rainy days. There are three levels of dimming for sequential flash lights. The power consumption of the first level is about 5% of the third level (the power consumption is proportional to the light intensity). If the light is only dimmed at the first level, it can be used for 6 hours every night for 60 consecutive rainy days.

[0082] Furthermore, the radio frequency unit 16 adopts a high-performance industrial-grade ZigBee chip, which adopts a low-power design and supports multi-level sleep and wake-up modes, can minimize power consumption, and can directly use a solar power supply system to provide DC power input without worrying about power consumption. This embodiment selects the 2.4GHz frequency band: this frequency band has the lowest impact on the airport's electromagnetic environment, and because the transmission power is extremely low, the impact on the airport's electromagnetic environment can be ignored. The communication method usually has a transmission distance of 10 meters to 70 meters. To ensure the reliability of the system, a high-gain module can be used to increase the RF transmission power, so that the transmission distance of Zigbee can be extended to 1-3 kilometers. Even the farthest flash light signal (900 meters) can be received by the wireless base station 1 module. Because each Zigbee is similar to a base station of a mobile network, they can communicate with each other within the entire network range. Even if there is a problem with the flash unit in the middle, it will not affect the operation of the entire system, thus ensuring the reliability of the operation of the entire flash system. The Zigbee chip is designed with a WDT watchdog to ensure the stable operation of the system and realize lightning protection of the antenna interface.

[0083] The beneficial effects of the present invention are as follows:

[0084] The present invention solves the power supply source problem of the LED light-emitting unit and the light source CPU by setting a large photovoltaic panel and a small photovoltaic panel respectively; increases the risk resistance of the system by setting a dual power supply line of the LED lamp; reduces the risk of the system being struck by lightning by setting a lightning protection module; realizes the detection function of the system fault and the fault feedback function by the photosensitive unit, the input voltage detection unit and the input voltage selection unit
