Study On Signal Acquisition And Processing Platform Of Vertical Hoisting System Driven By Permanent Magnet Linaer Synchronous Motor

In this paper, the advantages of permanent magnet linear synchronous motor vertical hoisting system in industrial production and research applications were introduced. The built industrial experimental model of vertical transportation system of single-side non-salient pole sectional permanent magnetic linear synchronous motor is the most practical model of linear motor transportation system with the height of 10 meters and the load of 1500kg. According to the industry model, the basic structure and operation principle of the vertical lift system based on permanent magnet linear synchronous motor are analyzed. Then the factors that influence the reliability and synchronism of PMLSM are found out. The factors that influence the stability of the vertical lift system. The required signals are determined. Through the analysis the signal's characteristics of the vertical lift system and the Fourier transform and the traditional wavelet transform in the signal processing. The method that use optimized Morlet wavelet in signal processing is proposed. Has determined this method feasibility through the Matlab simulation In this paper, TMS320LF2407 as a core component of signal acquisition and processing are used in hardware design. And use the chip ADS8364 achieve analog-digital conversion to the signals obtained of the vertical lift system, this chip have good matching with TMS320LF2407. Sets up the CAN communication network using TMS320LF2407 the bringing CAN Module. Through the RS323-CAN converter interface card to communicate with the Host Computer. C language and specific assembly language of TMS320LF2407 are used in software development, Play to their strengths. And also this paper use modular method for software development. The system software development is completed in the CCS2000 visual integrated development environment. Through the emulator to debug programs. In the end, through experiments to determined the feasibility of the signal acquisition and processing platform. This platform is meted to the needs of the signal acquisition and monitoring of the vertical lift system.
