基于单片机的儿童定位系统设计(含电路图,PCB图,程序代码)(任务书,开题报告,外文翻译,论文10000字,电路图,PCB图,程序代码)
摘要
由于近几年来我国老龄化的比例逐渐上升，独生子女的现象日渐普遍，作为孩子的父母的中年人工作压力与日俱增，有时候他们面对子女的安全健康以及他们的监护需求会显得力不从心。而且由于当前城市的道路日益复杂、行车安全事故频发，犯罪率也居高不下，这些问题给儿童的安全带来越来越多的不稳定因素。因此加强儿童实时的定位跟踪监控以便提高他们的出行安全就显得极为重要。
本文的核心内容主要涉及GPS的定位显示以及GPS信号的传输功能，主要应用了串口通信这一技术，将单片机接收到的GPS信号加以分析通过串口发送给GSM模块，然后通过短信的方式发送到监护人手机，以达到实时定位儿童的功能，以此来防止儿童的走失和被拐。本次硬件设计主要介绍了电源模块，单片机最小系统，液晶显示模块,GPS接收机模块，GSM/GPRS传感器模块，电平转换模块等。软件设计主要包括了主程序的设计，GPS传感器程序的设计，液晶显示模块程序的设计，串口程序的设计等。
本设计基本能够满足将儿童位置信息发送给监护人的要求，但是本设计仍需完善，希望能更好地服务于广大群众。 [资料来源：www.doc163.com]

The Design And Implementation Of Children Microcontroller-base positioning System
Abstract
     Because in recent years the proportion of population aging in our country gradually increased, the one-child phenomenon becomes more and more popular, as the parents of the children of middle-aged people working pressure increasing, sometimes they come face to face with the safety and health of children and their care needs appeared to be inadequate. And by road in the city becomes more and more complex, frequent traffic accidents, crime rate is also high, these problems to the safety of children bring more unstable factors. Therefore, to strengthen children's real-time positioning, tracking and monitoring so as to improve their travel safety is very important.
     The core content of this paper mainly involves the GPS positioning and GPS signal transmission function, the main application of the serial port communication technology, the microcontroller receives the GPS signal is analyzed through the serial port to send to the GSM module and the message will be sent to the mobile phone of a guardian, in order to achieve the function of real-time location of children, in order to prevent children from getting lost and abducted. The hardware design mainly introduces the power module, MCU minimum system, liquid crystal display module, GPS receiver module, GSM / GPRS sensor module, voltage conversion module. The software design mainly includes the main program design, G PS sensor program design, LCD module program design, the design of serial procedures.

     This design can basically meet the requirements of the child's location information sent to the guardian, but the design still need to improve, hoping to better serve the masses.
Key words: children location, GPS module, STC12C5A60S2 MCU, GSM module
