数字对讲型车载监控终端的设计与实现
摘要
随着国内外智能交通系统迅速发展,人们对车辆监控系统的要求也越来越高,各类车辆监控产品也不断更新发展,从传统的以GSM短消息作为数据通信方式的监控产品到现在以GPRS技术来进行实时数据通信的监控产品,在性能上有了很大改善。
本文通过对市场需求的认真分析,综合日益发展成熟的GPRS现代通信技术,利用GPS全球卫星定位系统和目前流行的GIS技术以及微计算机技术提出了一套数字对讲型监控调度终端系统方案。
本套系统在车载监控终端以MSP430单片机为核心,利用嵌入式C语言编程,充分利用单片机资源,完成GPRS网络传输所需要的适配驱动、链路控制、网络传输以及业务应用,从而实现GPRS技术在车载GPS卫星定位系统中的应用。在显示屏端利用凌阳单片机强大灵活的语音功能完成了语音的采集压缩,语音数据可通过车载监控终端的GPRS模块进行无线传输,通过监控中心的转发,实现终端与终端之间,终端与中心之间的语音对讲。
系统的功能多,可裁剪性与可扩展性强,可根据不同的客户需要进行配置,既满足用户需求,又为用户节约成本。通过GPRS无线网络来实现数字语音对讲,不受地域限制,可以在大范围进行语音对讲和语音广播,而且价格低廉。
As the rapid development of intelligent transportation systems, people want the performance of the vehicle monitoring system become more and more better. Various types of vehicle monitoring system are developping continuously, from the traditional monitoring system based on GSM short message service as the data communication mode to the new monitoring systems, which use GPRS to realize real-time data communication, and the performance is getting better and better.
This thesis analyzed the market information, used the GPS global position system, the micro computer science and integrated the modern GPRS to develop a digital walkie-talkie monitoring terminal system.
This monitoring system's terminal on car used the micro controller MSP430 as the core,and the embeded c program to accomplish the adapter driving,link control,network transmission and service application which is required by GPRS network transmission,and consequently realized using GPRS technology in GPS satellite position system on car. The sound sampling and compressing were accomplished by Sunplus micro controller's flexible sound function. Sound data can be transmitted wirelessly by monitoring terminal on car,so that transmmitting via monitoring center can realize tall-back between teminal and terminal or terminal and monitoring center.
This system has many functions, and can be clipped or extended easily, it can be customized according to different needs of customers, It can not only satisfy the customers,but also save the cost for customers. Use GPRS wireless network to realize digital sound tall-back is not confined by area,so it can accomplish sound tall-back or sound broadcast in large area,also,its cost is low.
