Description

Regional Airspace Management Surveillance System Based on TCAS System

technical field

The utility model relates to a management and monitoring system, in particular to an area management and monitoring system based on a TCAS system.

Background technique

TCAS (Traffic Alert and Collision Avoidance System), air traffic warning and collision avoidance system. The function of the TCAS system is to send an interrogation signal to adjacent aircraft, and obtain the code, altitude, heading and other data of the intruder aircraft through the response of the onboard transponder system of the intrusion aircraft to the interrogation signal. The TCAS computer judges the threat level of the intruding aircraft relative to the own aircraft through data analysis. If there is a potential threat, the TCAS system will issue an advisory prompt to the pilot, or issue a vertical maneuvering instruction to guide the pilot to avoid conflict with the intruding aircraft. If there is no threat, the TCAS system will display the relative position and trajectory of the intruder aircraft.

ADS-B stands for Automatic Dependent Surveillance-Broadcast. Aircraft equipped with the ADS-B automatic broadcasting system can broadcast its own precise position and other data (such as speed, altitude, and whether the aircraft is turning, climbing or descending, etc.) through the data link. The ADS-B automatic broadcast system is combined with the air traffic control system and the airborne ADS-B automatic broadcast system of other aircraft to provide accurate and real-time conflict information in the air and ground.

The control traffic control transponder is the airborne equipment of the air traffic control radar beacon system. Its function is to cooperate with the ground secondary radar and report the identification code and air pressure altitude of the aircraft to the ground control center. There are two types of answering machines, A/C mode and S mode. The air traffic control radar beacon system has also become the secondary system of air traffic control, which is composed of primary radar and secondary radar. The secondary radar cooperates with the airborne transponder and works in an inquiry-response mode. The ground secondary radar transmitter generates an interrogation pulse signal which is radiated by its antenna, and records that the transponder generates a corresponding response transmission signal after receiving an effective interrogation signal. After receiving the response signal, the ground secondary radar receiving surface performs a series of Process to obtain the required aircraft identification code and barometric altitude and other signals. The content of the information answered by the airborne transponder depends on the interrogation signal of the ground secondary radar. The mode of the interrogation signal and the way of interrogation are determined by the control center. The information content of the A-mode transponder response is the identification code of the aircraft, and the information content of the C-mode transponder response is the aircraft altitude information. The S-mode transponder, on the basis of having the functions of the A-mode transponder and the C-mode transponder, combined with TCAS, can realize data communication and exchange between aircraft in flight.

Since the airport area ground surveillance system is mainly based on radar and secondary radar, it uses a combination of tower control, approach control and area control to monitor airspace aircraft. However, due to the complex functions of this surface surveillance system, it needs to have a terminal area control system and an area control system, and hardware facilities such as radars and towers are often bulky and heavy, which is not only difficult to carry, but also consumes a lot of energy and costs high.

Because the equipment of the existing ground monitoring system in the airport area is huge, it is not conducive to handling, and its application environment will be limited to a certain extent. For example, in the 2008 Wenchuan earthquake in my country, due to the inconvenient transportation in the earthquake area, it was difficult to transmit ground information. The helicopters performing rescue missions could only rely on airborne equipment and pilots to obtain the surrounding airspace when performing flight missions. However, the high cost of equipment and maintenance of the ground monitoring system in the existing airport area has caused some small and medium-sized airports to bear a heavy burden.

With the development of my country's civil aviation, domestic civil aviation aircraft, large, medium and small airports and flight routes are increasing, especially the expansion of my country's military aviation airports and small and medium airports in the central and western regions, and the demand for regional airspace management systems is increasing. Therefore, providing a regional airspace management system with convenient mobility, powerful functions and moderate cost can effectively manage flights and routes, so that civil aviation aircraft can fly safely and orderly in the air, so as to protect the lives and property of passengers. important issues in construction.
