摘　　要：介绍了一种基于网络的超声波车流量检测系统的设计方案,通过超声波技术实现道路交通节点流量与流速的实时检测,同时引进单片机以太网传输系统,以较低的成本将检测信息方便地接入广域网络,使信息的远程获取及设备的远程控制成为可能.系统集成度高、性能稳定,可有效获取车流信息.It is basilic to get the vehicle flow in the Intelligent Transportation System （ITS）. The paper introduces a design of ultrasonic vehicle flow detection system based on Ethernet, which measures the vehicle flow and its speed by means of ultrasonic. Moreover, this design includes a single chip communication module, which sends the information detected to a long-distance host, and receives the command from the operator on the internet. The result of testing shows that the highly integrated system performs perfect and steady, which gives a reference to the structure of minitype sensors＇ network.
