Barrier information acquiring system and method of low-attitude airspace

Abstract

The invention provides a barrier information acquiring system and method of a low-attitude airspace. The system comprises a launching device, a data acquiring and handling device, a monitoring device,a maintaining device and a background, wherein the launching device is fixed close to a barrier and is used for storing the geographic data of a barrier and then regularly sending to an aircraft which flies nearby in a wireless manner; the data acquiring and handling device on the aircraft is capable of receiving the geographic data, determining the safety based on relative location, navigation direction and navigation speed, and reminding a pilot to avoid risk; the monitoring device is used for monitoring the working state of the launching device and reporting any fault of some launching device to the background through a special communication channel; the maintaining device is used for writing the geographic data of the barrier into the launching device and detecting the data accuracy.The system is not influenced by weather condition and is capable of rapidly supplying and acquiring the barrier location information; the system is high in maintaining performance, low in cost, low inenergy conservation, and environmentally friendly, and plays an important role in ensuring the flying safety in the low-attitude airspace.

Description

technical field [0001] The invention belongs to the field of aviation safety and relates to a technology for proactively providing obstacle information in low-altitude airspace, in particular to a system and method for obtaining obstacle information in low-altitude airspace. Background technique [0002] Low-altitude airspace (generally the airspace below 3000 meters) is an important part of airspace and the main space for general aviation activities. General aviation flight mainly depends on the pilot's judgment. Whether the pilot can identify the safe airspace in a timely and clear manner is very important to ensure flight safety. Unlike transport aviation with a mature system, general aviation has the characteristics of "low, small, and slow" flight, the route is not fixed, and the flight trajectory is difficult to predict. In addition, the low-altitude airspace environment is complex, the weather is changeable, and there are a large number of obstacles. The probability ...

AI Technical Summary

Problems solved by technology

In terms of equipment and facilities, the airborne equipment of general aviation aircraft is relatively simple, generally does not have radar capabilities, and mainly relies on the pilot's visual flight; the ground equipment mainly uses the method of setting aviation warning signs and warning lights to display the location of low-altitude obstacles. The method can solve certain problems, but it also has the following disadvantages: (1) The warning means using warning signs and warning lights is easily affected by the weather, and the display effect is reduced in cloudy and rainy days; Intelligent evasion strategies rely entirely on the judgment of the pilot's human brain, and the human influence factor is large; (3) The pilot must constantly observe the warning signs and warning lights, which is easily distracted and is not conducive to flight safety; (4) Currently, only civil aviation airports and nearby areas have installed The warning signs and warning lights of obstacles are far from sufficient compared with the general aviation flight requirements. If they are all installed in a wide low-altitude airspace, it will be a huge expense; (5) Regular inspections of the warning signs and warning lights are required. high maintenance cost

[0008] In short, the above patents all have problems in practical use, and are not suitable for obtaining obstacle information in low-altitude airspace
