摘要
介绍了工业以太网在高速公路隧道监控中的应用。由于以太网具有应用广泛、价格低廉、通信速率高、软硬件产品丰富、应用支持技术成熟等优点,目前它已经在工业企业综合自动化系统中的资源管理层、执行制造层得到了广泛应用,并已呈向下延伸直接应用于工业控制现场的趋势。本文以泰井高速公路隧道监控为例,详细介绍了工业以太网的特点、工业以太网与现场总线的比较、高速公路隧道监控工业以太网组网以及与上位机通讯。
Because of low expense, high communication speed, abundent procduct and mature support technology,Ethernet has been aboad appplicated on resource manage layer and executive manufacture layer of enterprise automation. Furthermore, it is a trend that ethernet extends to field control. By giving an example of Taijing Expressway tunnel supervisory control, this paper introduces character of industry Ethernet in detail, comparison industrial Ethernet with Fieldbus, networking and comunnication with supervisory computer.
