Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted ATC air traffic control transponder testing, in particular to an ATC air traffic control transponder testing system. Background Art

[0002] When an aircraft is flying, air traffic controllers can understand the flight path of each aircraft and the relative positions of each aircraft by watching the flight dynamic diagram on the ground station monitor, and command and dispatch the aircraft in a timely and accurate manner, so as to control the safe and orderly flight of the aircraft. This process is called "air traffic control". The purpose of air traffic control is to supervise and control all flight activities within the national airspace, prevent collisions between aircraft and aircraft, aircraft and ground obstacles or other flying objects, coordinate the use of airspace by various departments, and ensure flight safety. The ground air traffic control radar continuously sends out air traffic control radio frequency interrogation signals. After receiving the radio frequency interrogation signals that meet the regulations of the air traffic control system, the air traffic control transponder sends out the altitude and code of the aircraft. After the ground air traffic control radar captures the information of the aircraft (aircraft) in the air, it is processed by computer calculation to form an aircraft flight dynamic diagram (the flight path composed of the flight history position points and the current instantaneous position points of each aircraft, as well as its altitude, speed and aircraft identification code, etc.), which is displayed on the ground station monitor.

[0003] When the aircraft is undergoing ground maintenance, the ATC transponder's transponder function test is performed using an ATC transponder field tester instead of an ATC radar. This only checks whether the ATC transponder code and altitude transponder functions are normal, and cannot determine whether other ATC transponder data is normal.
