Description

General aircraft flight status automatic broadcast monitoring system and monitoring method

technical field

The invention relates to the technical field of general aircraft, in particular to a general aircraft flight state automatic broadcast monitoring system and a monitoring method.

Background technique

General aircraft refers to civil aircraft engaged in aviation activities other than public air transport. It has the characteristics of maneuverability, speed and efficiency. industry. General aircraft can perform tasks such as aerial photography, medical rescue, meteorological detection, aerial inspection, artificial precipitation, marine monitoring, land and offshore oil services, aircraft planting, and aerial fertilization, and plays a very important role in the national economy. According to the definition of general aircraft, business jets, private jets and civilian drones all belong to the category of general aircraft.

In recent years, the number of general aviation aircraft in my country has increased significantly compared with the past. It is estimated that in the next 5-10 years, the average annual growth rate of the number of general aviation aircraft will reach 30%. With the advancement of science and technology, the development of civilian drones is rapid, and it is constantly becoming practical. Due to the low practical cost of civilian drones and less dependence on ground facilities, general aviation projects such as aerial photography, aerial inspections, and aerial fertilization have been increasingly carried out by civilian drones. Industry insiders pointed out that with the development of China's economy, general aviation projects such as business flight, commercial flight, air tour, private driver's license training, drone aerial photography, aerial inspection, and aerial fertilization are becoming more and more popular. There is a huge market demand. This will inevitably lead to a situation of rapid development in the field of providing services.

However, there are problems in air control that need to be solved urgently. At present, my country's civil aviation control means mainly based on radar control. The types of radar used are Primary Surveillance Radar and Secondary Surveillance Radar. A small portion of the radio pulses emitted by a surveillance radar is reflected back by the target and retrieved by the radar for processing and display, showing only a bright spot on the display and no other data. The secondary surveillance radar is a radar system that coordinates the detected target with a matching device in the form of a transponder, which can display signs, symbols, serial numbers, flight numbers, heights and operating tracks on the display and special number. The coverage area of radar control is limited and the cost of equipment is high. It is mainly deployed in important areas, busy airports and areas along flight routes. It cannot completely cover all areas, and there are still a large number of monitoring blind spots.

ADS-B (Automatic Dependent Information Surveillance and Broadcasting System) technology is used in air traffic control, and can provide general aircraft with virtual radar control services that are superior to radar separation standards in mainland areas where air traffic control radars cannot be deployed; in radar coverage areas, even if there is no Adding radar equipment can also enhance the surveillance capability of the radar system at a relatively low cost, and increase the flight capacity of the route and even the terminal area. It is not too late to introduce ADS-B technology into our country, but the ADS-B communication frequency is limited in use in our country, making its development slow. Ground receiving systems cannot constitute effective regulatory coverage.

In recent years, the number of general aviation flights in my country has grown "blowout", especially the flying activities of low-speed and low-altitude light aircraft and civilian drones operating near cities have posed a threat to public safety. There is an urgent need for a system that can monitor the flight status of general aircraft, especially low-speed and low-altitude light aircraft and civilian drones.
