Embodiment Construction
[0046]The technical solutions in the embodiments of the present invention will be described clearly and in detail below with reference to the drawings in the embodiments of the present invention. The described embodiments are only some of the embodiments of the invention.
[0047] The technical scheme that the present invention solves the problems of the technologies described above is:
[0048] 1. Criteria for collision avoidance warning
[0049] In order to improve the accuracy of judgment and early warning, such as figure 2 As shown, this patent proposes a three-layer progressive judgment strategy:
[0050] ① Determine whether there are power lines around the drone;
[0051] ②Judge whether the UAV is gradually approaching the power line;
[0052] ③ Judging whether the distance between the UAV and the power line has entered the dangerous area and needs to start an early warning;
[0053] For ①, it can be judged by the value of the electric field intensity E obtained by...
