The Design And Implementation Of The Wearing Terminal Positioning System Based On Android

With the rapid development of the popularity of intelligent terminals and mobile Internet, " Internet + " has become a new trend of the social development. As the popularity of Wearing terminal technology with GPS function, based applications and mobile wearing terminal on " Internet + " that become the new favorite for contemporary society. Many problems remain highly concerned by parents, society and the relevant government departments, for example: getting lost of unwise people, losing of children and etc. In order to solve problems, combined with the current scientific and technological achievements as well as corresponding for the government requirement, intelligent wearable terminal positioning system came into being.This paper is based on the Android smart system development and design, the server is based on Struts2, Spring3 and Hibernate3 frameworks by Java. The terminal is composed of a GPS positioning device and GSM/GPRS module components. In background of high concurrency, compared to other papers design of Android-based positioning system, this paper uses Nginx server technology, for getting higher load-balancing capabilities with the help of Nginx's high concurrency. The wearing terminal positioning system is an Android program which is under the Apple Mac system, so this paper firstly introduced the building of Android platform under Apple Mac systems, followed by introduction of GPS technology, Baidu Maps technology, Jroo framework Google open source and data encryption key technology. Next the design and implementation of the module function is introduced. Finally, the paper takes a functional testing for the system's function in the method of test case, which contains expected results, so it's more efficient.Through the demand analysis of wearing terminal positioning system, the paper realized the following functions, like Terminal location positioning navigation; Alarm for import and export; Adding guardian at terminal; Historical footprints inquiry; Drawing the electronic fence and binding terminal. Because the system uses the terminal to support the GSM module, so you can also make a phone call. As this paper uses Nginx load balancing technology, so this paper server can theoretically support up to fifty thousand concurrency. In this paper, the server is based on SSH framework, so the back-end server development not only saves costs, but also improve the efficiency of development and progress.After a period of testing and improvement, the wearing terminal positioning system which is based on Android that has been delivered to a company. It will be placed on the market and benefit afterwards. This paper designed a wearing terminal system based on the mobile intelligent system, reflecting the trend of the current mobile era, also in response to the government's call. So we are highly believed that intelligent terminal products based on mobile intelligent systems will be better.
