Description

Technical Field

[0001] The present invention belongs to the technical field of aviation radio communication, and relates to a method for sharing an air avoidance position based on satellite positioning by presenting a real-life scene of an aircraft, and in particular to a portable air avoidance warning system and method. Background Art

[0002] During the flight of an aircraft, the ground usually relies on air traffic control secondary radar, ADS-B and other systems to monitor and direct the aircraft. Each aircraft sends and receives information such as their respective locations through the ADS-B system.

[0003] The existing air traffic control secondary radar has the disadvantages of low-altitude surveillance blind spots and a small amount of information transmitted by the system. It can only be used for ground surveillance and tracking of aerial targets, and cannot be used for communication and position confirmation between aircraft.

[0004] Due to the design requirements of some aircraft and the fact that some old aircraft were not equipped with the ADS-B system when they were designed, and the high cost of installing ADS-B airborne flight monitoring equipment on board and the high cost of deploying monitoring base stations on the ground, it is impossible to use ADS-B technology to monitor and transmit information between them, and they can only rely on ground command and pilots' visual perception and avoidance. When there are many test aircraft at the same time and the density is high, there is a great risk of mid-air collision. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a portable air avoidance warning system and method, which realizes air avoidance warning of aircraft in a low-cost and fast-configuration manner.

The first high-frequency antenna, the second high-frequency antenna, the satellite antenna and the wireless antenna are plugged into the interface of the wireless self-organizing network core control host. The power supply module is connected to the wireless self-organizing network core control host and provides power.

[0008] Furthermore, the core control host of the wireless ad hoc network performs long-distance high-frequency wireless transmission and modulation and demodulation of information within the local area network and overall control of the signal wireless terminal; the first high-frequency antenna and the second high-frequency antenna receive and send 1.4GHz frequency band wireless data information to complete the satellite positioning information data transmission between multiple aircraft flight avoidance warning devices; the satellite antenna receives satellite positioning information; and the wireless antenna completes the data communication between this early warning device and the ground control terminal.

[0009] Furthermore, multiple early warning devices are set up, and one of them is selected as a ground command and monitoring device. All early warning devices use the first high-frequency antenna and the second high-frequency antenna to complete networking and send and receive information to each other; the early warning device serving as a ground command and monitoring device is placed in a tower or ground station.

[0010] Furthermore, the software of the ground control end includes a setting module, a following warning module and a display monitoring module; the setting module sets the warning device, including the landing object setting and the avoidance warning setting; the following warning module warns the aircraft's flight altitude and the flight distance between different aircraft according to the content of the avoidance warning setting; the display monitoring module provides a display interface, which displays the current position, altitude, heading, and speed of all networked aircraft against a map background. The display monitoring module also records the flight routes of all networked aircraft and can display the routes that all networked aircraft are traveling.

[0011] Furthermore, a follow button and a positioning button are provided in the display monitoring module; after pressing the follow button, the follow mode is entered. In the follow mode, the map background of the display interface cannot be dragged, the currently selected aircraft is displayed in the center, and the map background moves with the currently selected aircraft; after pressing the positioning button, the positioning mode is entered. In the positioning mode, the map background no longer moves with the currently selected aircraft.

[0012] Furthermore, a playback button is provided in the display monitoring module. After clicking the playback button, the query interface is entered. By selecting the information record of the flight code, time, pilot, and aircraft number, the flight record of the aircraft can be found, and the flight trajectory can be played back by clicking the flight record.

[0013] Furthermore, a route button is provided in the display monitoring module. After selecting an aircraft, click the route button to display the route of the selected aircraft in the display interface; after clicking the route, enter the route editing interface, enter the latitude and longitude of the waypoints and the route sequence in the route editing interface and save, and complete the setting of a new route or the change of an old route; without selecting an aircraft, directly click the route button to display the routes of all networked aircraft.
