一种获取行驶速度的简易方法

A Method of Getting Tracked Vehicle′s Velocity

针对多谱勒雷达测速仪价格昂贵,而在车辆的传动部位安装传感器的测速方法需要对车辆进行解体,操作复杂等缺点,提出一种降低测量误差,间接获得车辆行驶速度的简易方法,即通过在履带车辆主动轮附近安装光电传感器,利用数字式磁带机采集车辆行驶时光电传感器拾取的脉冲信号,通过M ATLAB对脉冲信号进行数据处理,从而获得车辆行驶速度.该方法简化了测速过程,可以利用简单的操作快速获得较精确的结果.利用某履带车辆完成了该方法的测速实验,并与相关的测速方法进行了结果对比,说明此方法的实用性和可行性.通过实验结果说明该实验方法可以广泛地应用于履带式车辆的测试中,具有一定的通用性.

In view of the high cost of Doppler radar velocimeter and the complexity operauon of settng sensors at the moving parts of vehicle, a indirect method to reduce error is put forward. By setting the photoelectric sensors near the sprocket of tracked vehicle and recording the pulse signal with the taper recorder, the velocity of tracked vehicle is got after processing with Matlba. The testing procedure is simply. Through the experiment on certain tracked vehicle and comparsion with relative testing method, it is practicability and feasibility. It indicates that this method can be used in the experiments on tracked vehicles and has definite applicability.
