基于单片机的多功能背包的设计

Design of Multi-functional Backpack Based on Single Chip Microcomputer

本文通过采用STC89C52单片机作为主控芯片,利用SERF GS1100 GPS接收模块对书包的UTC时间与经纬度进行分析,得到背包当前所处的经纬度与海拔高度;利用ADXL345加速度计对背包的运动状态进行分析,得到背包的运动距离。系统设计完成后,背包利用LCD1602液晶显示器显示经纬度、海拔高度等数字信息。实验结果表明,多功能背包可实现定位、监测、导航、计步等功能,定位误差在10 m以内,面对户外等复杂环境,背包的稳定性好,续航时间长,功能丰富。

In this paper,STC89C52 single chip microcomputer is used as the main control chip,and SERF GS1100 GPS receiving module is used to analyze the UTC time,latitude and longitude of the schoolbag,so as to obtain the current latitude and longitude and altitude of the backpack;using ADXL345 accelerometer to analyze the movement state of the backpack,the movement distance of the backpack is obtained.After the system design is completed,the backpack uses LCD1602 to display longitude,latitude,altitude and other digital information.The experimental results show that the multi-functional backpack can realize the functions of positioning,monitoring,navigation,step counting and so on.The positioning error is within 10 meters.Facing the complex environment such as outdoor,the backpack has good stability,long endurance time and rich functions.
