Helicopters are widely used in many military and civilian applications due to their unique flight capabilities, maneuverability, and lower site requirements. The helicopter can fly in a low-altitude and complex environment and has the characteristics of vertical take-off and landing, hovering in the air and the like. The advantages of low-altitude flight capability, low site requirement and the like of the helicopter are accompanied by certain risks. For example, when working in a low-altitude and complex environment, the crane is susceptible to the influence of the geographical environment and the wires and cables, and may cause serious damage to the safety of the helicopter. Wherein, the wire collision hazard belongs to the important hidden danger of low-altitude flight safety.
Compared with a fixed wing airplane, the helicopter has more field taking-off and landing tasks, and is greatly influenced by terrain and ground objects when flying over mountainous areas, forest areas and towns. The distribution of electric wires and cables in cities, towns and rural areas in China is dense, the height of the electric wires is low and difficult to identify, and the height of the helicopter is not high, so that the probability of collision between the helicopter and low-altitude electric wires and cables is increased.
