摘　　要：针对目前国内路面弯沉检测精度差、效率低的问题,设计了嵌入式激光弯沉测定仪.该测定仪采用ARM7处理器,并植入μC/OS-Ⅱ嵌入式操作系统,通过对新型激光位移传感器无线数据的采集,完成弯沉值的计算、存储、显示、分析等功能.实验结果表明弯沉误差可控制在0.01mm以内,一个断面的测试时间仅为60s左右.该测定仪具有体积小、携带方便、功耗低等特点.In order to improve precision and efficiency of pavement deflection testing, a test instrument based on embedded operating systemμC/OS-Ⅱ was designed with ARM7 processor. From collectingwireless data of laser displacement sensor, pavement deflection was calculated, stored, displayed and analyzed. The experiment results show that test error of pavement deflection is controlled below 0. 01mm and test time is about 60 seconds. The instrument has many other advantages, such as small volume, convenient portability, low-power consume and so on.
