【摘要】：人口老龄化是人类社会进步的必然产物。随着老龄人口的比重不断增加,养老问题将逐步被放大。世界范围内的公共养老和医疗机构都面临着巨大压力,因此有国外学者提出“居家养老”的概念,用以提升老人的生活质量并缓解公共资源粥少僧多的现状。而使“居家养老”落实的一个重要环节正是防止老人走失,老人定位系统由此诞生。在中国,老人走失问题尤为严重,而且多发生于偏远山区。传统的老人定位系统多利用GPS进行定位,之后将定位信息通过GPRS/GSM传输至远程服务器,但在部分基站信号无法抵达的偏远山区无法适用。而且单GPS定位的精度也难以得到保证。基于上述背景,本文设计了一种基于北斗导航和Android平台的老人定位系统,该系统主要包括三个模块:手持定位终端、作为数据后台的服务器以及作为客户端的Android应用程序。对于手持定位终端部分,本文选用了BDS/GPS双模定位芯片进行定位,根据BDS/GPS联合定位原理,双模定位能在一定程度上提升定位精度。在一般情况下,手持定位终端将定位信息通过GPRS技术传输给服务器,但在移动基站信号无法到达的偏远山区,需要使用北斗导航系统独有的短报文通信方式传输信息。本文提供了一种适用于老人定位系统的短报文通信方案,并验证了方案的可行性。服务器部分,本文采用阿里云服务器作为硬件基础,My SQL作为数据库管理系统,PHPmyadmin作为远程数据库交互界面。文中对系统所需的数据库关系表进行了设计,并编写了相应的PHP脚本程序对数据库进行特定的增删改查操作。Android应用程序部分,本文根据老人定位系统的需求,设计了应用程序的主要功能模块。之后配置Android开发环境并采用Android Studio编写代码。应用程序部分主要工作包括:交互界面的设计、用户登录注册短信验证码功能实现、实时定位相关功能实现以及Android网络编程(与服务器进行数据交互)。最后本文对老人定位系统进行了整体测试,主要包括:Android应用程序与服务器端数据库交互测试,实时定位精度检验与电子地图相关功能测试,对短报文通信方案进行传输数据测试。
[Abstract]:Population aging is the inevitable outcome of the progress of human society. With the increasing proportion of the aged population, the pension problem will be magnified step by step. Worldwide public pension and medical institutions are facing great pressure, so some foreign scholars put forward the concept of "home old-age care", in order to improve the quality of life of the elderly and ease the public resources congee more than the status quo. An important link in the implementation of home-based old-age care is to prevent the elderly from losing, and the elderly positioning system is born. In China, the problem of loss of old people is especially serious, and often occurs in remote mountain areas. The traditional location system for the elderly usually uses GPS to locate, and then transmits the location information through GPRS/GSM to the remote server, but it can not be used in remote mountain areas where some base station signals can not be reached. Moreover, the accuracy of single GPS positioning is difficult to be guaranteed. Based on the above background, this paper designs an elderly positioning system based on Beidou navigation and Android platform. The system mainly includes three modules: handheld positioning terminal, server as data background and Android application as client. For the handheld positioning terminal part, the BDS/GPS dual-mode positioning chip is selected for positioning. According to the principle of BDS/GPS joint positioning, dual-mode positioning can improve the positioning accuracy to a certain extent. In general, the handheld positioning terminal transmits the location information to the server through GPRS technology, but in the remote mountainous area where the mobile base station signal can not be reached, it is necessary to use the short message communication mode which is unique to the Beidou navigation system to transmit the information. This paper provides a short message communication scheme for the elderly location system, and verifies the feasibility of the scheme. In the server part, this paper uses Ali cloud server as the hardware base, My SQL as the database management system, PHPmyadmin as the remote database interactive interface. In this paper, the database relational table required by the system is designed, and the corresponding PHP script program is written to carry out a specific add and delete operation to the database. Part of the Android application program, according to the needs of the elderly location system, The main function modules of the application program are designed. Then configure the Android development environment and use Android Studio to write code. The main work of the application program includes: the design of interactive interface, the realization of the function of user login and registration short message verification code, the realization of real-time location-related function, and the Android network programming (data interaction with server). Finally, the paper tests the elderly location system, including: Android application program and server database interactive test, real-time positioning accuracy test and electronic map related function test. The transmission data of short message communication scheme is tested.
