基于CDMA网络现代化信息采集系统的设计与实现

The Design and Realization of Modernized Message Collecting System based on CDMA Network

交通信息的采集、处理和传输是智能交通管理系统的重要构成部分.描述了一种基于CDMA网络的信息采集终端的软硬件的设计和仿真实现方法.系统由51单片机I、nsight系列仿真器、BCM-860 CDMA模块以及配套的开发板构成,终端具体功能的实现是在Medwin的软件环境下,用AT命令控制CDMA模块来实现.

The collection, processing and transmission of traffic information is an important part of intelligent traffic management systems. This paper describes a designing and emulating method of the hardware and software of CDMA network-based collecting terminals, which is composed of 51-singlechip-control system, Insight emulators, BCM - 860 CDMA module and auxiliary developing board. The terminal＇s specific functions are realized under the environment of Medwin software by using AT command to control CDMA modules. The successful development of the system is of great significance in networking message communication, establishing message communication platforms, and realizing the timely, accurate message transmission among people, cars and roads.
