Research Of Denoise And System Analog Of Electric Control Door

The electric control door is widely used in public security fields because of its reasonable price performance. But the noise made when the door is closed is far beyond national correlative standards , and make serious noise pollution. The article put emphases on the mechanize of the electric control door through experiments on the spot and emulation of computer, then advance that the root of noise is that the design has defects .The safe close of the door is depended on the impulsion of door normal impacts. The design hardly has denies measures so that it is convenient to use while its noise is loud'The article analysis the prime factors of noise quantitatively through the fervency spectrum, and make the ways object to noise, in that it is suggested to improve the energy storage system and raise the system control capability to the moving door so to slow the close velocity. All this can resolve the problem of noise.To have better effects of denoise, this article propose that the core of denoise is to control the noise driving source adding to develop transmission path of noise.
