【摘要】 分析了定位监控系统的设计,该系统由信息处理模块、GSM(全球移动通信系统)模块、GPS(全球定位系统)模块以及中心台等部分组成。重点介绍利用GPS接收模块接收GPS信息,并对接收到的数据进行处理,提取经纬度等信息,通过GSM网络发送到控制台,然后在监控中心利用导航软件根据传送来的信息实行定位、调度、监控等功能。介绍了利用TI16C554实现多路串口通信,并设计了一种利用TI16C554实现多路串口通信的硬件应用电路。更多还原

【Abstract】 This paper analyses a design of long-distance locating and control system.It is composed of information-handling module,GSM module,GPS module and control center.This paper elaborates that using the GPS module to receive the GPS information,and handle the data we have received to get the information such as longitude and latitude,then send these information to control center by GSM net,so the center and catch the location through the GIS on computer according to the information and carry out the function as long-distance control.This paper introduces realization of multiple serial communication using TL16C554,and describes a hardware circuit using TL16C554 for realizing multiple serial communication.更多还原
