多路共梁式激光车辙检测仪的研究与实现

Research and development of rut detector based on multiway laser sensor

对由52路TCD1208线阵CCD、单片机W77E58、现场可编程门阵列EPF10K10和以太网芯片RTL8019AS组成的高速路面车辙检测仪的实现方案进行了研究。阐述了线阵CCD驱动信号的产生、多路CCD数据的高速采集、UDP协议的组包及通讯、上位机软件系统的编制等多个重要环节的实现方法。在此基础上搭建了具有52路激光传感器的高速车辙检测车,对我国多条高速公路以及省国道进行了车辙检测。

Research an implementation of high speed rut detector which consist 52 routes of TCD1208 linear CCD, W77E58 for singlechip microcontroller, EPF10K10 for FPGA and RTL8019AS for Ethernet.Expatiate some important implementation methods as producing of drive signal for linear CCD, multiway CCD data collecting, communication and packet composing of UDP protocol, upper computer software programming and so on.Based on that realized the project of multiway laser rut detector and detect many freeway, national highway, provincial highway.
