The Design And Implement Of Traffic Signal Control Software Based On Android

With the unprecedented development of Computer Techology, the operating system updates rapidly. Among all operating systems, Android won the developers’ favor by the feature of openness and good compatibility. The best technology in IT industry should be fully applied to every walk of life, especially to transport industry which is closely linked with people’s life.The2000-IIB traffic signal control system in ShengMao corporation can regulate traffic signal light effectively,but the sofeware was based on Windows platform and not convenient.Therefore,develop it in Android system is very necessary.This paper put forward a designing scheme of traffic signal control system based on Android, and achieved it. Firstly, introduced the main function of2000-IIB Model Centralized Coordination Traffic Signal Controller, and Android’s framework, four component, the development platform and so on.According to the function of Signal Controller, made a detail requirement analysis of the software, include functional architecture, index and logic relation of login, road, cross, basic settings, conflict, phase, timing, day, week and holiday.Then, designed flow chart of each functional module, mostly used listview and edittext, the down key automaticly checked parameters change. Analysed multiple parser method to deal with xml file, explored the most suitable technique——Dom.In the end, expounded the implementation procedure. Read road and cross file in specified path of SD card, achieved some operation such as automatic match, add, delete, copy, upload and download. Fullfilled logic relation of each parameter interface. Read xml data and converted to interface information, amended interface data and transformed to configure information. Communicated with Signal Controller in AngDa v702, transferred the newest configure data to control traffic semaphore.
