摘要
常见的基于GPS和GIS的车辆监控系统通常使用SMS作为通信手段,SMS不具备专用通道,难以扩展以适应其它的数据业务,因而难以在某些特殊条件下提供稳定的通信服务。相对于SMS而言,GPRS价格低廉、实时、稳定,从而更适用与这样的监控系统。给出一个基于GIS与GPRS相结合的车辆监控系统的软硬件设计方案与实现,重点介绍系统的架构、设计及软件的实现,并通过实验对系统性能进行分析。
Most of vehicle monitoring systems based on GPS and GIS technologies use SMS as their communicating means. SMS didn＇t have private channel and is difficult to extend to suit other data business, could not afford stable communicating in those systems in some special situations. Contrasting with SMS, GPRS is cheap, real time and is more stable, and more suitable for those systems. A vehicle monitoring system that using GPRS and GIS is introduced, including the architecture, design, and the implementing of software is emphasized, also.
