摘　　要：为了削弱传统五轮仪法测量结果受地表情况的影响,提出了一种基于光电编码器双路测量间距的方法。结合自制的行进装置,把单片机系统采集到的位置信号作为外部中断信号,用来控制计数两路编码器脉冲信号的启停,并利用归纳出的算法得出两个位置信号间的距离。In this passage,a method has been introduced which used to measure distance based on photoelectric encoder from two routes ,In order to weaken traditionary fifth wheel method＇s influence from the earth＇s surface .with the self-made traveling device ,it needs single-chip microprocessor system collecting position signal as external interrupt, so as to control Count＇s startup and stop from two-routes pulses. Eventually ,the distance of two position signals can be get according to inductive algorithm.
