摘要:
传统的超声测距是基于测量超声反射回波所耗费时间的方法而进行的,该方法无法实现两个分离点目标距离的测定. 本文设计了一种利用红外同步信号控制两个分离点目标的测距系统. 文中阐述了该方法的实现原理,给出了收发分离超声测距系统的电路设计,分析了收、发两端超声波传播过程中产生的时间误差来源,并修正了超声波测距公式,以提高测量精度. 该系统电路实现简单,测距精度可达到1.5 mm左右,具有很好的实际应用价值.
Abstract:
Traditional ultrasonic ranging is based on the method of ultrasonic echo delay. This method cannot achieve two separated points for ranging. The paper designs a distance-detecting system by using an infrared synchronization signal to control two separated targets. The paper illustrates in detail the principle of the method and this circuit design of ultrasonic ranging system is given. It also analyzes the delay error of two separated points and correct the ultrasonic ranging formula,improving the accuracy of measurement. The circuit is easy to implement and the ranging accuracy is 1.5 mm. So the system has a high practical value.
