摘要
针对传统的测距系统精度不高,测量中长距离时偏差比较大,提出一种基于单片机的超声波测距系统的设计方法,该方法采用了温度补偿电路,提高了测距系统的精度。实验结果表明:该方法弥补了现有测量方法的不足,大大提高了测量精度,节省时间,设计简单,具有可行性。
Aiming at the shortcomings of the traditional ranging system, such as high accuracy and large deviation in long- distance measurement, a design method of ultrasonic ranging system based on single-chip microcomputer is proposed. The temperature compensation circuit is adopted to improve the accuracy of the ranging system..Experimental results show that this method can make up for the deficiencies of existing measurement methods, greatly improve the measurement accuracy, save time, design is simple and feasible.
