高速公路信息传输技术正日益成为支撑高速公路日常运营管理网络的重要手段,其主要是以通信系统为载体,用特定的传输方式实现高速公路收费或路况等信息的采集、上传和发布。该文在分析、对比高速公路信息传输技术在监控网络系统中应用的基础上,重点阐述了以太网传输模式相对于串口通信模式在高速公路信息传输中的应用优势。
Expressway information transmission technology is increasingly becoming an important means of supporting the day-to-day operation and management network of expressways. Its main purpose is to use the communication system as a carrier to realize the collection, upload and release of information such as highway tolls or road conditions by a specific transmission method. On the basis of analyzing and comparing the application of expressway information transmission technology in monitoring network system, this paper focuses on the application advantages of Ethernet transmission mode relative to serial port communication mode in highway information transmission.
