超声波测距系统中抗干扰措施的研究

Research on Anti-interference Measures for Ultrasonic Metering Distance System

在分析超声波测距原理的基础上,设计了基于单片机控制的测距系统.通过分析超声波的回波窜绕、传播速度与环境温度的关系等对测距系统的影响,提出了一些抗干扰的措施,设计了超声波接收处理电路和温度补偿电路.

On the basis of analyzing ultrasonic metering distance principle, a metering distance system based on single chip microcomputer control is designed. Some anti -interference measurements are proposed by analyzing ultrasonic echo wave interference, transmitting speed and environmental temperature working on the metering distance system. Then a ultrasonic receiving circuit and temperature compensate circuit are designed.
