The invention discloses a traffic flow information acquisition method and system, is applied to the technical field of automobile intelligent identification, and is used for solving the technical problem that vehicle information cannot be conveniently and accurately acquired in existing road vehicle identification. The method provided by the invention comprises the following steps: detecting the dynamic state of a vehicle in a preset triggering area in real time through radar; sending a trigger signal to an ETC antenna corresponding to the radar when the detected vehicle dynamic state conformsto a preset state; awakening the working state of the ETC antenna to be a running state through the trigger signal; and when the working state of the ETC antenna is a running state, identifying the vehicle information of the vehicle through a microwave signal sent by the ETC antenna. The system comprises a power supply module, radar, an ETC antenna and a server, the power supply module is connected with the radar and the ETC antenna, the server is in communication connection with the radar and the ETC antenna, and when the traffic flow information acquisition system operates, the steps of thetraffic flow information acquisition method are realized.

    本发明公开了一种交通流信息的采集方法和系统,应用于汽车智能识别技术领域,用于解决现有的道路车辆识别存在无法便捷又准确地采集车辆信息的技术问题。本发明提供的方法包括:通过雷达实时探测位于预设的触发区域内的车辆动态;当探测的车辆动态符合预设状态时,向与该雷达对应的ETC天线发送触发信号;通过该触发信号将该ETC天线的工作状态唤醒为运行状态;当该ETC天线的工作状态为运行状态时,通过该ETC天线发送的微波信号识别该车辆的车辆信息。该系统包括电源模块、雷达、ETC天线和服务器,该电源模块分别与该雷达和该ETC天线连接,该服务器分别与该雷达和该ETC天线实现通信连接,该交通流信息的采集系统运行时实现上述交通流信息的采集方法的步骤。
