摘要

目前

智能交通系统(ITS)在对高速公路可变情报板通讯稳定性和可靠性提出了更高要求的同时

也提出了情报板应具备能够根据不同环境灵活采用最为简便有效的通讯方式、适应多种复杂环境能力的需求。针对这一情况

结合嵌入式技术和网络通讯技术

提出一种嵌入式公路可变情报板通讯系统。该系统采用MC703CDMA EV-DO 3G模块和DM9000CIEP网络芯片

借助于Linux操作系统强大的网络功能

使其同时具备3G无线网络通信、10/100M自适应以太网通信、RS485串行接口通讯多种通信方式

在保证系统高效稳定通信的同时可根据具体环境选用不同的通讯方法

具有很高的灵活性。

Abstract

Currently

intelligent transportation systems (ITS) proposed a new demand that the VMS should have the ability to choose the most simple and effective means of communication according to the different environments as well as higher demands in the stability and reliability of the communication. In view of this situation

combined with the embedded technology and network communication technology

this paper proposed a communication system based on embedded highway VMS. The system uses MC703CDMA EV-DO 3G module and DM9000CIEP network chip

combined with the powerful networking capabilities of Linux operating system

has the ability of 3G wireless network

10/100M adaptive Ethernet communication and RS485 serial interface communication. The system has high effectiveness and stability in communication

at the same time it can selected different communication methods according to the specific environment.
