摘要
本文介绍了一种超声波导盲系统的设计,硬件电路部分包括主控芯片STC89C52单片机、LCD1602液晶显示、ISD1730语音播报、HC-SR04超声波模块和按键3软件部分由C语言编写,使用KEIL4软件完成软件设计,并进行了简单的机械结构设计。通过对硬件电路的实验测试,对比系统测量距离值和实际距离值,显示存在一定的误差,但在允许范围以内,表明该超声波导盲系统的设计方案合理可行。
It introduces the design of an ultrasonic guidance system for the blind.The hardware circuit includes STC89C52 MCU,LCD1602 LCD display,ISD1730 voice broadcast,HC-SR04 ultrasonic module and keys.The software part is written in C language and KEIL4 is used.Simple mechanical structure design is carried out.It shows that the designing scheme of ultrasonic guidance system for the blind is feasible,although there are some errors(within limits),by conducting experimental measurement for the hardware circuit and contrasting the measured distance value and actual distance value of the system.
