An early warning will be issued intelligently when ADS-B aviation lights sensed the aircraft

   Aviation obstruction lights, as the name suggests, are a type of sign specifically designed to provide warning for aircraft flying or taking off and landing. In recent years, the altitude range of aircraft flying around the world has gradually expanded, and low altitude flight has gradually become popular. In order to prevent accidents caused by the impact of visual field on structures during low altitude flight, aviation warning balls and obstacle lights have emerged.

   According to the Convention on International Civil Aviation and relevant national regulations, aviation obstruction lights are mostly used on river crossing transmission line towers, Tower block in airport clearance protection areas, and 220 KV and above transmission towers in China. Low intensity aviation obstruction lights are always on, while medium intensity aviation obstruction lights and high intensity aviation obstruction lights are flashing. The flash rate shall not be less than 20 times per minute and shall not exceed 70 times per minute. Generally, low light intensity is used in conjunction with medium and high light intensity obstacle lights. At present, low and medium intensity aviation obstacle lights are generally powered by solar energy, while high intensity obstacle lights are extremely strong and generally powered by 220V lines.

   The main purpose of installing aviation obstacle lights is to display the contour of the structure, enabling aircraft operators to determine the height and contour of obstacles, and to serve as a warning. In general, high intensity obstacle lights will be installed on the tower of ultra-high voltage transmission lines, with three layers of sequential flashing, located at the top of the tower, the lowest point of the wire sag, and the center of both. The brightness of medium to high intensity lights is extremely bright, thus consuming a lot of electricity. The conventional method is to use solar panels and batteries for power supply. In order to ensure that the aviation obstacle light can still work normally in continuous rainy and cloudy weather for 20 days, it is necessary to equip it with super large capacity batteries and high-power solar panels, which greatly increases the cost of the system and also brings inconvenience to workers who install it at heights.

   Through ADS-B technology, aviation obstacle lights can see the "aircraft" and achieve more intelligent early warning. When the aircraft does not enter the detection set range, the obstacle light flashes at a relatively low intensity or turns off the power supply of the lamp. When the aircraft is detected to enter the set range, the light source is activated and the set brightness is used for warning. Through this method, the system power consumption can be reduced to within 10% of the original, greatly saving costs and increasing system stability and reliability.
