摘要：

为更加精准和快速地检测路面的高程数据，设计了一种基于逐次二角法理论与ARM芯片的路面不平度测量系统。该系统通过旋转编码器采集行驶距离和角度变化，以自研发ARM采集系统采集分析数据，采用Modbus通讯协议进行上位机信息交互，通过实际测量，定点距离测量准确率达9992%，定点角度测量准确率达9967%。在路面单线测量中与水准仪所测数据相比准确率可达927%，最大偏差＜54 mm。

Abstract:

In order to detect the pavement elevation data in a more accurate and fast way, designing a new measurement system based on Two Angles method and ARM chip. The system collects traveling distance and angle change by rotary encoder, and through the ARM acquisition system acquisition and analysis data, through the Modbus communication protocol, the host computer information interaction, In actual measurement, the accuracy rate of the system is 9992%, and the accuracy of the fixed point angle measurement is 9967%. In the single line measurement of pavement and the level of the measured data compared to the accuracy rate of up to 927%, the maximum deviation is less than 54 mm

Key words: road roughness;successive two angle method;ARM chip;programmable digital filter, Modbus communication protocol
