Description
Technical Field
The invention relates to the technical field of general aircrafts, in particular to an automatic broadcast monitoring system and a monitoring method for flight states of general aircrafts.
Background
The universal aircraft is a civil aircraft engaged in aviation activities except public air transportation, has the characteristics of flexibility, rapidness, high efficiency and the like, and the operation projects cover multiple industries such as agriculture, forestry, pasturing, fishing, industry, building, scientific research, transportation, entertainment and the like. The universal aircraft can execute tasks such as aerial photography, medical rescue, meteorological detection, aerial inspection, artificial precipitation, ocean monitoring, land and offshore oil service, airplane seeding, aerial fertilization and the like, and plays an important role in national economy. By definition of a general purpose aircraft, public aircraft, private aircraft, and civilian unmanned aircraft are all in the general aircraft category.
In recent years, the number of universal aircrafts in China is greatly increased compared with the past. The annual average growth rate of the number of general aviation airplanes is expected to reach 30% in the next 5-10 years. With the progress of science and technology, the development of civil unmanned aerial vehicles is rapid and practical. Because the civil unmanned aerial vehicle is low in practical cost and small in dependence on ground facilities, general aviation projects such as aerial photography, aerial inspection, aerial fertilization and the like are increasingly executed by the civil unmanned aerial vehicle. The people in the industry point out that with the development of Chinese economy, general aviation projects such as official flight, commercial flight, air tourism, private driving license training, unmanned aerial vehicle aerial photography, air inspection, air fertilization are receiving more and more people's favor, have huge market demand. This necessarily leads to a rapidly evolving situation for the domain for which the service is provided.
However, the problems in air control are to be solved. At present, the civil aviation control means of China mainly takes radar control as the main control. The types of radar used are primary and secondary surveillance radar. A small fraction of the radio pulses emitted by a surveillance radar are reflected back by the target and are retrieved by the radar for processing and display, showing only one bright spot on the display with no other data. A secondary surveillance radar is a radar system that coordinates a measured target with a device in the form of a transponder, which displays on a display signs, symbols, numbers, flight numbers, altitude and trajectory, etc. and special numbers. The coverage area of radar control is limited, the equipment cost is high, the radar control is mainly arranged in important areas, busy airports and areas along flights, all areas cannot be completely covered, and a large number of monitoring blind areas exist.
The ADS-B (automatic relevant information monitoring and broadcasting system) technology is used for air traffic control, and can provide virtual radar control service superior to radar interval standard for general aircrafts in continental areas where navigation management radars cannot be deployed; in a radar coverage area, the monitoring capability of a radar system can be enhanced at a lower cost even if radar equipment is not added, and the flight capacity of an airway and even a terminal area is improved. The ADS-B technology is not introduced into China late, but ADS-B communication frequency is limited in use in China, so that the ADS-B communication frequency is slow to develop. The ground receiving system cannot constitute an effective control coverage.
In recent years, the increase of the number of general aviation flights in China in a blowout mode, particularly the flight activities of low-speed low-altitude light airplanes and civil unmanned planes which move near cities, threaten the public safety. A critical need arises for a system that can monitor the flight status of general-purpose aircraft, particularly low-speed low-altitude light aircraft and civilian drones.
