Early warning method and system for barriers

Abstract

The invention discloses an early warning method and system for barriers. The method comprises the steps that barrier information on a flight route of an airplane is acquired; the barrier information comprises information of types of the barriers, the outlines of the barriers, the heights of the barriers and the positions of the barriers; dangerous space zones of the barriers are determined according to the barrier information; the flight states of the airplane is acquired; the flight states of the airplane comprise information of the speed of the airplane, the height of the airplane and the position of the airplane; the time needed for the airplane to enter the dangerous space zones of the barriers is calculated according to the flight states of the airplane and the dangerous space zones of the barriers, and endangered time is obtained; when the endangered time is smaller than a set threshold value, and an alarm signal is sent out. According to the method and the system, when the airplane gets close to the barriers, the alarm signal is sent out, a pilot or a control center is reminded to make reaction in time, and safe influences of the barriers on low-altitude flight of the airplane are avoided.

Description

technical field [0001] The invention relates to the technical field of aircraft safe flight, in particular to an early warning method and system for obstacles. Background technique [0002] In the prior art, in addition to being used for military affairs and carrying passengers, airplanes are also widely used in technical fields such as pesticide spraying, short-distance transportation, medical rescue, disaster relief, emergency rescue, hoisting equipment, geological exploration, forest protection and fire fighting, and aerial photography. However, when the aircraft is used in some of the above fields, such as pesticide spraying, hoisting equipment, geological exploration, forest protection and fire fighting, and aerial photography, the flying altitude of the aircraft is relatively low, and such flying altitudes are prone to encounter various problems during the flight. When the aircraft encounters an obstacle, the aircraft is vulnerable to the impact of untimely evasion and...

AI Technical Summary

Problems solved by technology

However, when the aircraft is used in some of the above-mentioned fields, such as pesticide spraying, hoisting equipment, geological exploration, forest protection and fire fighting, and aerial photography, the flying altitude of the aircraft is all low, and such flying altitudes are easy to encounter various problems during the flight. When the aircraft encounters an obstacle, the aircraft is vulnerable to the impact of untimely avoidance and causes serious flight accidents, which threatens the life safety of the pilot and affects low-altitude operations.
