摘要
介绍一种分布式微小位移精确测量系统,该系统基于网络通信技术,采用FPGA和线阵CCD实现。在系统中,通过FPGA逻辑设计实现线阵CCD的高速驱动,使线阵CCD的数据传输率达到每秒5000帧,网络通信技术实现了数据的远距离传输和支持多站能力,基于VB平台编写PC机控制程序。系统已应用在一维微小形变的测试中,可以支持32个线阵CCD测试节点,节点数据传输长度大于1000m,测量精度达到100μm。
A precise micro-displacement measurement system based on network communication is introduced.Network communication,FGPA and the linear CCD are adopted in the system.The linear CCD generates 5000 line data per second.The FPGA processes the data synchronously.The network communication is applied to implement long-distance data transmission and multi-station communication.The hardware system is controlled by the PC control program,which is developed by VB6.0.The whole system demonstrates high reliability,and it is applied in the one-dimensional micro-displacement measurement system with a precision of 100 μm.
