摘要
本文基于STC89C51单片机,设计并制作了一款视障人群安全监护系统。该系统包含光线检测模块、显示模块、语音播报模块、超声波测距模块。其中光线检测模块利用光敏电阻采集光线信号,语音播报模块采用NY3P035语音芯片,超声波测距模块采用HC-SR04超声波传感器。大量的实验测试表明该系统在很大程度上保障了视障人群出行安全,达到了无忧出行的目的。
Based on STC89C51 MCU,a safety monitoring system for visually impaired people is designed and made.It includes light detection module,display module,voice broadcast module and ultrasonic ranging module.The light detection module uses photoresistor to collect light signals,the voice broadcast module uses NY3P035 voice chip,and the ultrasonic ranging module uses HC-SR04 ultrasonic ranging sensor.A large number of experimental tests show that the system ensures the travel safety of visually impaired people to a great extent and achieves the purpose of worry-free travel.
