基于CX20106A的超声波测距设计

摘要

文中介绍了基于CX20106A的超声波测距系统的设计与实现方案。以At89e52单片机作为中央处理器（mcu）控制协调整个设计的发射接收和数据处理，然后通过独立的R/T-16超声波发生和接受模块产生和接收超声波。以此两者之间的时间差来判断距离的大小，然后有单片机程序计算出障碍物与发射探头的距离。同时，使用DS18B20做为单片机的温度补偿来提高单片机测距中的精确度。最后使得这个设计更加精确、可靠、简便的实现现实生活中的各项测距工作。%This article introduced the ultrasonic ranging system based on CX20106A design and implementation scheme.With At89c52 microcomputer as the central processor （MCU） control coordination of the overall design of the data transmitting and receiving and processing.Then through the independent R/T-40-16 ultrasonic generating and receiving module for generating and receiving ultrasonic.Using the time between the two detector to determine the distance of the obstacle, then the MCU program calculates the obstacle and the transmitting probe distance.At the same time, the use of DS18B20 as a single chip temperature compensation to improve ranging accuracy.Finally makes the design more precise, reliable, easy to achieve real life in the distance.
