Early warning method and system for avoiding aircraft ground collision

Abstract

The invention discloses an early warning method and system for avoiding aircraft ground collision. The early warning method comprises the steps of: collecting the steering angle of an undercarriage front wheel of an aircraft and the ground speed of the aircraft; acquiring obstacle information around the aircraft, wherein the obstacle information comprises distance information, direction information and image information; calculating the safety boundary of the aircraft based on the aircraft configuration data, the steering angle and the ground speed in combination with preset collision risk response time; generating an aircraft environment image based on the obstacle information; and adding a virtual image used for representing a safety boundary on the basis of the aircraft environment image to form an early warning image, and displaying the early warning image to a driver. According to the early warning method and system for avoiding aircraft ground collision, the surrounding environment of the ground can be automatically sensed or monitored, necessary early warning prompts are automatically sent to pilots in real time in combination with configuration data of the aircraft, and therefore, the risk of aircraft ground collision can be avoided.

Description

technical field [0001] The invention relates to aircraft airborne equipment, in particular to an early warning method and an early warning system for preventing aircraft ground collisions. Background technique [0002] At present, during the ground taxiing phase before takeoff or after landing, the aircraft mainly relies on the pilot's vision or the command of the tower to prevent the accident of the aircraft from colliding with the ground. This method relies too much on the experience and judgment of relevant personnel, and the safety and reliability are not high enough. Especially when there are unconventional situations on the airport ground, the pilot may not be able to make the best judgment and decision based on experience. [0003] Therefore, it is urgent to provide an early warning method that can automatically sense or monitor the surrounding environment on the ground, automatically send necessary early warning prompts to the pilot, and effectively assist the pilot ...
