摘　　要：国内目前钢板测宽仪,其结构复杂,控制繁琐,需要标定,以及及时维护,实时操作性差。本文在原有的钢板在线测宽仪的基础上,提出了一种改良型的系统。系统中采用经济的线阵CCD成像系统。在本文中介绍了测量方法,以及原理,应用CPLD与单片机结合采集与处理测量数据,和边缘细化技术提高测量精度。整套系统结构简洁,成本低廉,抗干扰性能好,调试方便。The domestic present width measuring instrument of steel plate, its structure is complex, controls tediously, needs to de-marcate, as well as prompt maintenance, real-time operation difference. This article proposed one kind of improving system base on the original width measuring instrument of steel plate. The system adopted the economical line array CCD. Introduced the measuring technique in this article, and improving the measure accuracy by subdividing the edge of CCD signal. Combed CPLD and MCU tech-nologies to gather and process the survey data. The structure of system is simple, cost low grade, anti interference ability fine, and debugging is convenient.
