Embodiment

[0019] A kind of air traffic collision early warning method based on Beidou, comprises the steps:

[0020] Step 1, the monitored aircraft and the ground monitoring station use the timing function of Beidou to synchronize the clock;

[0021] The Beidou system has the function of time service, and it is only necessary to synchronize the clock of the ground monitoring station and the clock of the collision warning system of the regulated aircraft with the clock of the Beidou system.

[0022] Step 2: The monitored aircraft obtains its own state information, and sends the state information to the ground monitoring station at fixed intervals using the synchronized clock.

[0023] The monitored aircraft obtains the status information of the current aircraft, and the status information mainly includes the aircraft identification code, speed, position, altitude, time when the status information is sent, etc.

[0024] The method of obtaining its own state information includes the posit...

Abstract

The invention discloses a Beidou-based air traffic collision early warning method, which comprises the following steps: 1. the monitored aircraft and ground monitoring station use a time service function of the Beidou to synchronize a clock; 2. the monitored aircraft acquires the state information, and transmits the state information to the ground monitoring station at fixed intervals by using the synchronized clock; and 3. the ground monitoring station continuously receives the state information transmitted by the aircraft by using the Beidou system, performs preliminary collision screening and collision time prediction according to the state information and gives an alarm according to the prediction result. The method is simple to implement and low in irradiation and does not have a blind area. According to the method, the collision early warning can be independently performed, and the method can serve as backup of a traffic collision avoidance system and other collision early warning equipment, and is a beneficial supplement.

Description

technical field [0001] The invention relates to an air traffic collision early warning method in the aviation field, in particular to a method for realizing air traffic collision early warning by using Beidou. Background technique [0002] With the urgent demand for aviation applications and the country's strong support for the aviation industry, the aviation market is booming. With the increase of aircraft, especially the increase of general aircraft, air collision warning in air traffic control becomes more and more important, although some aircraft are equipped with TCAS (Traffic Collision Avoidance System, traffic collision avoidance system) system, TCAS equipment Collision warning is carried out by communicating and coordinating with the TCAS equipment of the surrounding aircraft, but the TCAS system still has deficiencies, such as short range, large radiation, etc. In addition, the general aircraft with less people is usually not mandatory due to the fewer people it ca...
