Embodiment approach
[0059] According to some preferred embodiments of the present invention, the early warning method also includes:
[0060] In response to the landing gear system of the aircraft sending a wheel-loaded signal indicating that the aircraft is on the ground, the steering angle of the nose wheel of the landing gear of the aircraft and the ground speed of the aircraft are collected, and the obstacle information around the aircraft is collected.
[0061] According to some preferred embodiments of the present invention, the early warning method further includes: collecting the wheel speed of the front wheel of the landing gear, and replacing the ground speed with the wheel speed in the calculation process of the safety boundary in the case of failure to collect the ground speed.
[0062] The following combination Figure 2-4 For an application example of the early warning method for preventing aircraft ground collisions according to the above-mentioned preferred embodiment of the prese...

The invention discloses an early warning method and system for preventing aircraft ground collisions. The early warning method includes: collecting the steering angle of the front wheel of the landing gear of the aircraft and the ground speed of the aircraft; collecting obstacle information around the aircraft, wherein the obstacle The information includes distance information, direction information and image information; based on the aircraft configuration data, steering angle and ground speed, combined with the preset collision risk response time, calculate the safety boundary of the aircraft; generate aircraft environment images based on obstacle information; On the basis of the aircraft environment image, a virtual image used to represent the safety boundary is added to form an early warning image, and the early warning image is displayed to the driver. According to the early warning method and system for preventing aircraft ground collisions of the present invention, the surrounding environment on the ground can be automatically sensed or monitored, and combined with the aircraft's own configuration data, the necessary early warning prompts can be automatically sent to the pilot in real time, thereby avoiding aircraft ground collisions risks of.
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 ...
