Title  Application of neural network algorithm in elevator guide rail straightening system
Abstract
The elevator is an essential automation equipment of modern high-rise building, and the straightness of the elevator guide rail is an important factor in the stability of the high-speed elevator. In order to make the elevator guide rail achieve the accuracy requirements, the guide rails are generally required to go through the straightness detection and straightening before leaving the factory. In order to improve the production efficiency and the accuracy of guide rail, the artificial neural network has been introduced into the hardware and software platforms of the developed elevator guide rail straightening system. By learning a lot of straightening pressure point samples from successful experiences, the system can accurately find the mapping relation among the bend value of the pressure point, the distance between the supporting points and the pressure point and straightening stroke. 源自!六%维^论*文`网www.lwfree.cn
This paper begins with a brief overview of the hardware and software platforms of the developed elevator guide rail straightening system, Secondly this paper introduces the basic theory of neural network, LM algorithm and steps. Then this paper describes how to use neural networks based on MFC programming to calculate and predict the overvoltage. This paper focuses on realizing the training and simulation processes of the samples based on MFC program and introduces how to apply neural network algorithm into the elevator guide rail straightening system. Finally this paper introduces the application of neural networks were expanded for a particular case. The improved algorithm can not only effectively improve the guide rail accuracy but also increase the production efficiency.
