广东东软学院本科生毕业设计（论文）本科毕业设计（论文） 基于单片机的北斗定位系统的设计Design of Beidou positioning system based on single chip microcomputer 摘要现代社会空巢老人越来越多，老人因意外发生不能及时呼救给健康甚至生命安全带来威胁，因而，老人安全监护受到越来越多的关注。为了解决这一问题，本次设计使用了 STC12C5A60S2 单片机作为主处理器，以 UM220 模块作为核心，结合 LCD12864 显示模块、蜂鸣器、SIM900 模块，实现了多功能报警系统。如果老人或弱势群体发生意外情况，按下报警按键，蜂鸣器响起，液晶屏上显示病例、过敏史、药品位置等，还能通过按键切换到位置地址信息。并通过 GSM 无线通信模块将定位信息发送到家人手机中，使伤者得到及时救援。实验结果表明，本系统能够准确实现报警、定位和信息显示功能，为安全监护提供解决方案。关键词：北斗定位系统；单片机；信息采集；GSM 通信广东东软学院本科生毕业设计（论文）AbstractThere are more and more empty nesters in modern society. The elderly can't call for help in time due to accidents, which brings threats to health and even life safety. Therefore, more and more attention has been paid to the safety monitoring of the elderly. In order to solve this problem, STC12C5A60S2 single chip microcomputer is used as the main processor, um220 module as the core, LCD12864 display module, buzzer and sim900 module are combined to realize the multi-functional alarm system. If the elderly or vulnerable groups have an accident, press the alarm button, the buzzer will sound, the case, allergy history, drug location, etc. will be displayed on the LCD screen, and the location address information can also be switched through the button. And through the GSM wireless communication module, the location information is sent to the family cell phone, so that the injured can be rescued in time. The experimental results show that the system can accurately realize the functions of alarm, lo...
