【摘要】 随着计算机技术和定位技术的快速发展,许多厂商都研制并生产出了适用于个人或者特殊行业的移动定位产品,这为人们的出行提供了极大的便利,尤其是一些车辆定位及管理系统,大大提高了交通的管理效率。而本课题所研究的移动定位产品,是面向中小型用户的,具有成本低、功能可靠的优点。本系统包括移动定位终端和监控中心两个部分,其中每个部分都是硬件和软件的统一体。本人的设计工作主要包括如下几个方面:参与系统架构的提出;相关硬件产品的选择;移动定位终端设备的GPS定位模块的外围接口电路板和主控模块电路板的设计、组装及调试;监控中心数据采集软件的设计与编程实现。本系统采用了GPS定位技术,可以提供全天候的定位功能,同时可以提供精确的速度信息等;移动终端的主控模块部分采用一个单独的2051单片机作为扩展串口芯片,这使得中心处理器能够同时响应GPS定位接收机和GPRS/SMS无线通讯模块的请求;移动定位终端和监控中心服务器之间的通讯采用两种方式:SMS短信和GPRS无线网络。本系统所使用的硬件、技术,都是基于性价比的考虑,使得本系统成本低、功能可靠,并且通过软件的升级,可以轻松地扩展系统的功能。更多还原

【Abstract】 With the rapid development of the computer and positioning technology, a great number of manufacture develop their products for mobile positioning. All of these give us more convenience during travel and improve the traffic management. This paper proposed a mobile positioning system made for low-end users. This system features in low cost and high stability.This system consists of mobile positioning terminal and mornitor center all of which include software and hardware implementations. My job mainly includes: system structure proposal; hardware products selection; GPS receiver peripheral circuit and main controller module circuit design; data collection software design and implementation.This system is based on GPS technique, which can offer round-the-clock positioning function; a 2051 processor is used to expand serial interface in main controller module, so that the main processor can respond to the GPS module and GPRS/SMS module simultaneously; the communication manner between mobile terminal and mornitor center include: SMS messages and GPRS.This system is suitable for low-end users because the cost was carefeully considered when we were selecting hardware products and technique. And its function can be expanded easily by software update.更多还原
