基于单片机的智能视力宝的设计与实现

Design and Implementation of Intelligent Vision Protector Based on Single Chip Microcomputer

以单片机STM32F103作为主控制器,采用超声波传感器HC-SR04、陀螺仪传感器GY521-MPU6050、语音模块LP-TTS、光敏电阻、若干继电器等一系列模块构成了智能视力宝。它通过检测坐姿与书本之间的距离来帮助学生纠正自己的坐姿,并通过对周遭环境的检测实时调整照明亮度,达到保护视力的目的。重点描述了超声波测距模块的设计和实现。

An intelligent vision protector is designed,which takes a single chip microcomputer STM32F103 as the main controller and uses the ultrasonic sensor HC SR04,gyroscope sensor GY521 MPU6050,voice module LP-TTS,photosensitive resistance,a number of relays and a series of modules.The detection of position and the distance between the eyes and books is achieved,to help students to correct their posture.And the brightness can be adjusted in real time through the detection of surrounding environment,to achieve the purpose of protecting eyesight.This paper describes the design and implementation of the ultrasonic ranging module in detail.
