Abstract

Sensor technology is the main content of modern information technology is one of access to information and control system an important part of the overall system greatly influence the function of the sensor technology is widely used in industrial fields as well as basic science studies, many countries have sensors technology research in national research strategy important position. Photoelectric sensor has a non-contact , fast response and reliable performance characteristics,and can measure many parameters,the structure is simple,flexible and perse forms, therefore,with the development and popularization of photovoltaic technology , photoelectric sensors to detect and control applications will be very extensive.

FPGA as high-speed large -capacity low-power digital devices , can be used to control the DC motor ,and can improve system speed precision and control. This paper discusses the function of photoelectric sensors , applications , FPGA features and application of the background , foreground, introduces ACTEL company FLASH FPGA advantage. And FLASH FPGA as the core, in-depth study of the design of the system required hardware modules , designed and built with FLASH FPGA interface photoelectric sensor and motor control circuits , using Verilog hardware description language in Actel 's Libero IDE platform launched on the design, the design of a photoelectric sensor controller solution. By FLASH FPGA for voltage monitoring,gate drive functions , complete the FPGA of the sensing signal acquisition, processing and motor control procedures,and gives practical debugging results.
