摘要
利用AT89C52单片机作为主控制器,进行系统硬件和软件的设计.通过介绍超声波测距测距仪的原理,超声波发射模块的原理及电路构成,超声波接收模块原理及电路构成,以及温度补偿电路的原理,设计出了以AT89S52单片机为核心的低成本、高精度、微型化数字显示超声波测距仪的硬件电路和软件控制系统.
Using single-chip AT89C52 as the master combined with the principle of ultrasonic distance measurement to design the hardware and software of system. It is introduces the principle of ultrasonic range finder, and the principle and circuit of an ultrasonic transmitting module and ultrasonic receiving module. The circuit of the temperature compensating, it is designed with AT89S52 MCU as the core of low cost, high precision, miniaturization digital display ultrasonic range finder hardware circuit and software control system.
