Abstract


Steel strip non-contact vibration measurement has important industrial application in foreign countries have been exploring but domestic researchers unpopular . This thesis is based on the strip vibration edge detection problem targeted design a non-contact wireless data acquisition system based on FPGA, USB and linear array CCD , is mainly used in the steel strip vibration detection . Firstly, starting from the linear array CCD , a systematic analysis of the basic working principle of the CCD , the characteristics and applications of , and in accordance with the requirements of the acquisition system , the whole system is divided CCD driving circuit module acquisition module, data buffer module ARM platform and display output module . In-depth discussions on the key issues of the specific application of CCD - driven timing circuit realization . Secondly , this paper presents the implementation process based on the FPGA- line array CCD driver circuit using Verilog language description Altera Corporation , QUARTUS Ⅱ simulation software driver designed to drive timing circuit . Finally , the simulation and actual test results prove the feasibility of a data acquisition system proposed in this paper , combined with the system software needs to complete the host computer 's wireless communications test program .
