Description

Bird self-adaptive expelling method for electric power tower area and bird expelling rod mechanism Technical Field The invention belongs to the technical field of power transmission equipment maintenance, and particularly relates to a bird self-adaptive expelling method and a bird rod expelling mechanism for an electric power tower area. Background In the running environment of the existing power transmission line, the residence, nesting and activity behaviors of birds on the power tower are still one of the main external factors affecting the safe and stable running of the line. Particularly, due to large size and wide range of motion, the behaviors such as wing spreading, excretion or nest carrying and the like of large-sized birds are easier to cause faults such as interphase short circuit and tripping, and the operational reliability of a power system is seriously threatened. In order to solve the above problems, various bird repellent devices and control methods have been proposed, including physical structures such as a bird repellent windmill, a bird repellent cover, and a bird repellent board, and terminal devices using bird repellent means such as sound, light, and electricity, and bird image recognition algorithms are used to implement corresponding expelling actions after specific birds are recognized. A database, a control strategy library and the like are also introduced into part of the schemes so as to match the bird repelling strategy according to the bird species or the appearance time. However, the following key problems are common in the prior art through analysis: In most of current bird repellent systems, physical structure prevents birds and has played certain anti-bird effect, but prevent bird windmill, anti-bird cover, anti-bird chopping block etc. still have certain tripping operation to take place, can't avoid bird pest tripping operation to take place completely. The bird-repellent method of the terminal equipment of the bird-repellent means such as sound, light and electricity is a preset fixed value aiming at different birds, the bird-repellent method does not dynamically change along with actual bird-repellent results, although the system can record identification results and execution instructions, an effective feedback association mechanism is lacking between bird-repellent parameters and bird-repellent effects, under the condition that a plurality of sets of terminal devices are deployed in a region, the system does not establish a linkage response strategy based on global unified scheduling, bird-repellent strategies cannot be shared or migrated, and each terminal is isolated to operate. The above-mentioned drawbacks lead to a core problem in that when birds of the same species repeatedly stay on the same tower or adjacent towers, repeated use of the same expelling parameters will cause birds to react adaptively to the bird expelling action, resulting in a decrease in expelling efficiency and even complete failure in severe cases. Disclosure of Invention Aiming at the problems in the prior art, the invention provides a bird self-adaptive expelling method and a bird expelling rod mechanism for an electric power tower area, and solves the problems that birds generate adaptive reaction to bird expelling behaviors, so that the expelling efficiency is reduced and even completely fails when birds of the same kind stay on the same tower or adjacent towers repeatedly in the prior art.
