The centralized control station 11 controls the tower lighting and take-off and landing guidance lights based on the data.

[0083] The functions of each system in this application are as follows:

[0084] (1) ADS-B system4

[0085] ADS-B stands for Automatic Dependent Surveillance-Broadcast, a new air traffic control monitoring technology based on the global satellite positioning system and using air-to-ground and air-to-air data links to achieve traffic monitoring and information transmission. It automatically broadcasts the aircraft's position, altitude, speed, heading and other flight parameters through airborne and ground equipment. This information is transmitted between aircraft or between ground stations in a mesh or many-to-many manner through data link broadcasting.

[0086] (2) Secondary Surveillance Radar

[0087] Secondary Surveillance Radar (SSR) refers to a radar that can monitor active reflective targets in controlled airspace. Compared with the primary radar used to monitor passive reflective targets, the secondary radar can emit a certain pattern of interrogation signals and receive reply signals from the transponder of the active reflective target. After the reply signals are processed, the code, altitude, azimuth and distance of the active target equipped with the transponder can be displayed.

[0088] (3) Multi-point positioning system 3

[0089] The positioning principle of multi-point positioning technology is based on the hyperbola and hyperboloid positioning algorithm of time difference of arrival (TDOA). The arrival time TOA of the same reply signal received by different receiving stations is matched to obtain the time difference TDOA of the reply signal to different stations, which can be converted into the distance difference from the target to different receiving stations. According to the definition of hyperbola and hyperboloid, a TDOA value corresponds to a hyperbola or a hyperboloid containing the target position. The intersection of two hyperbolas is the position of the target in a two-dimensional system, and the intersection of three hyperboloids is the position of the target in a three-dimensional coordinate system.

[0090] (4) UAV detection and countermeasure system 8

[0091] As an important detection tool, the drone detection system can monitor the position and altitude of drones with high precision, long distance and comprehensiveness. It has high-precision target positioning capability, can track multiple drone targets at the same time, realize multi-target track tracking, has strong anti-interference performance, can still work normally in complex electromagnetic environments, has the characteristics of rapid response, can quickly detect the appearance of illegal drones, and issue alarms in time.

[0092] Due to the difficulty in regulating illegal drones, they have brought many hidden dangers to the aviation industry, and also brought new ways for terrorist attacks and espionage reconnaissance, causing concerns among governments. The anti-drone system can effectively solve this problem. The system consists of radar + jammer, uses low, small and slow radar technology, can detect high / low speed targets all day long, uses highly accurate horizontal and tilt azimuth indicators, automatically tracks and identifies drones, uses intelligent RF suppressors, can selectively interfere with different types of control communication links used by drones, can form drone no-fly zones, and ensure flight safety around airports.

[0093] (5) 360-degree high-definition monitoring system7

[0094] It includes multiple high-definition cameras and safe and reliable communication links, which can transmit high-definition images of the airport in real time and display them on the large-screen display of the control center, making it convenient for air traffic controllers to understand the situation in each branch airport.

[0095] (6) 5G communication system 5

[0096] The fifth generation of mobile communication technology (5G for short) is a new generation of broadband mobile communication technology with the characteristics of high speed, low latency and large connection. 5G communication facilities are the network infrastructure for realizing the interconnection of people, machines and things. When drones are operating at low altitudes, they need to maintain communication with the ground and receive instructions. The ground also needs to track and feedback the flight status of the drone and issue instructions in a timely manner. All these behaviors rely on network communication.

[0097] (7) High-power bird repellent system 9

[0098] Although birds are small in size and do not fly very fast, they are enough to pose a major threat to the flight safety of aircraft. Every year, many flight safety accidents caused by bird strikes occur, which also cause a lot of economic losses. Therefore, high-power bird repellent devices are installed around ladder-type high pole lights or airports to protect the safety of various aircraft and equipment without killing birds.

[0099] The principle of ultrasonic bird repellers is to use ultrasonic technology to drive away birds. Specifically, these devices emit high-frequency ultrasonic waves to interfere with, stimulate and damage the nervous and physiological systems of birds, causing physiological disorders, thereby achieving the purpose of driving away birds. Ultrasonic bird repellers usually have an output frequency of more than 16k-20kHz. These high-frequency sounds are in the range that birds are sensitive to, but higher than the frequency that the human ear can perceive, so they can drive away birds without harming them.

[0100] (8) Fresnel lens take-off and landing lighting guidance system 10

[0101] Small piston aircraft will encounter the influence of altitude error when landing, which may cause the pilot to misjudge the altitude control and lead to accidents. In order to solve the correction of altitude error, a guidance system based on Fresnel lens is used. The system can be set on the runway or high pole. The light is directed to the mirror and then reflected into the air, providing the pilot with a descending slope of light (with an angle of 3.5 to 4 degrees with the runway plane). The pilot follows this slope and corrects the error with the position of the aircraft in the mirror until it lands safely.

[0102] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
