[Abstract]:Avionics with ground-to-air communication function in avionics system plays an increasingly important role in the real-time monitoring of aircraft. An airborne monitoring system with ground-to-air communication function is added to the aircraft to communicate with the ground through high frequency, very high frequency or satellite, which can realize the real-time monitoring of the aircraft. This is essential to ensure the flight safety of the aircraft and to search the aircraft in time when an accident occurs. Because our country is highly dependent on foreign communication technology and satellite communication system, it is urgent for the domestic civil aviation industry to install an airborne monitoring system based on Beidou satellite navigation system. In order to improve the stability of the loading system and reduce the influence on the normal flight of the aircraft, it is also very important to study the modification scheme of the airborne monitoring system. The airborne monitoring system based on Beidou is a ground-to-air communication assistant system which uses the short message communication function of Beidou satellite navigation system to realize the aircraft monitoring and control, and realizes the function of data transmission between ground and air. According to the functional requirements of the system for real-time monitoring of aircraft, the design, implementation and loading scheme of the system are studied. The airborne monitoring system is composed of two subsystems: airborne subsystem and ground monitoring subsystem. The realization mode of the core software of the airborne system and the realization of the ground monitoring and displaying software are put forward. The operation method of Beidou communication module and the method of software development with MySQL database. On the basis of the airborne monitoring system, the modification scheme on the aircraft is studied, including the power supply scheme, the signal acquisition scheme and the determination of the modification position. In order to verify the feasibility of the system and the modification scheme, the system is tested. In the laboratory environment, by using industrial control computer, Beidou user computer and other equipment to build the whole hardware-in-the-loop simulation platform, and input flight data to the system to verify the function of the airborne monitoring system. That is, verify that each functional module can work properly, verify that all the modules can be integrated together to set the functional requirements. The test results show that the airborne monitoring system can meet the functional requirements of real-time monitoring of aircraft.
