GPS车辆定位系统监控软件的关键技术分析与设计

The Technical Analysis and Design of The GPS Vehicle Position System Software

本文以采用SMS(短消息)模块的车辆监控系统为应用背景,对GPS车辆监控系统的需求进行了分析,在需求分析的基础上,采用了一种非常适用于通信设备终端软件的设计方案———用户界面、通信服务、数据服务三层式模型。在这三层中,重点论述了有很大技术难度的通信服务层的设计方案,该方案以异步通信和多线程技术为核心,大大增强了通信部分的效率、可靠性和可控制性。

Basing on the vehicle position system using the SMS module,we analyse the requirements and bring forward a three-layered model,which is very appropriate for the communications softwareIt consists of the user interface layer,the communications services layer and the data services layerWe focus on the communications services layer that is the technical key of this modelA scheme is designed to combine the asynchronous communications and multithreading technologyIt will improve the efficiency,reliability and controllability greatly
