一、制定背景利用地感线圈的电磁感应原理,判断道路上有无机动车辆通过,对通过的机动车辆进行统计、分析和测速,是各地方的交通管理部门最常用的手段。相对应的产品有很多,如:机动车卡口监控系统、机动车超速自动监控系统、机动车闯红灯电子警察抓拍系统、机动车逆行抓拍系统、道路机动车占有率统计系统以及停车场自动管理系统等,都是利用地感线圈作为传感器进行抓拍、测速和对数据进行统
First, the development of the background The use of induction coil induction principle, to determine whether the motor vehicle on the road through the motor vehicle statistics, analysis and speed, is the most common means of traffic management at all localities. The corresponding products are many, such as: motor vehicle bayonet monitoring system, vehicle speeding automatic monitoring system, vehicle running red electronic police capture system, vehicle retrograde capture system, road vehicle occupancy statistics system and automatic parking management system Etc., are using the coil as a sensor to capture, speed and data on the system
