The invention relates to a traffic flow information collecting and sending device, and belongs to the field of intelligent traffic control. At present, a ground induction coil and the like are adopted for traffic flow detection of a road traffic signal machine, road surface excavation is needed for installation and maintenance of detection and acquisition equipment, construction is inconvenient, and the detection and acquisition equipment is prone to damage, and electronic police equipment used at an intersection at present has a traffic flow detection function. However, traffic flow information collected by electronic police equipment is difficult to send to a signal machine in real time, so that although the signal machine has a self-adaptive phase adjustment function, self-adaptive phase adjustment cannot be carried out. According to the traffic flow information collecting and sending device, traffic flow information collected by electronic police equipment can be collected in a network cable or bus mode, and the information is sent to the traffic flow information receiving and converting device in a wireless or bus communication mode; and the traffic flow information receiving and converting device transmits the traffic flow information to the annunciator in an IO output mode or a bus mode.
本发明是一种车流量信息采集发送装置,属智能交通管控领域。在目前的道路交通信号机,对于车流量的检测采用的是地感线圈等,这些检测采集设备安装和维护都需要开挖路面,施工不便且易损坏,而目前路口使用的电子警察设备带有车流量检测功能,但电子警察设备所收集的车流量信息却难以实时发送到信号机,造成信号机虽带有自适应相位调节功能,也不能进行自适应相位调。本发明一种车流量信息采集发送装置,可采用网线或总线方式来采集电子警察设备采集的车流量信息,并将信息通过无线或总线通信的方式发送到车流量信息接收转换装置,再由车流量信息接收转换装置通过IO输出方式或总线方式将车流量信息传到信号机。
