车牌自动识别系统高速公路收费、监控管理的应用
Application of license plate automatic recognition system in expressway toll collection and monitoring management
车辆的自动放行：此项功能针对如特种车辆（如军车、警车）、预交费车辆（如办理月、年缴费卡）以及其他授权免费通行的车辆。系统处于自动检测状态，一旦发现该类车辆经过，给出的控制信号不是驱动拦截装置，而是驱动放行装置。系统此时会自动开启道闸，达到车辆不停车过卡和减少工作人员、严化内部管理的目的。通常用于高速公路卡口专用车道。其作用是可以解决车流高峰期的堵塞问题和减少运作费用。
Automatic release of vehicles: this function is for special vehicles (such as military vehicles and police vehicles), pre paid vehicles (such as handling monthly and annual payment cards) and other vehicles authorized to pass free of charge. The system is in the state of automatic detection. Once the vehicle passes, the control signal given is not to drive the interceptor, but to drive the release device. At this time, the system will automatically open the gate, so as to achieve the purpose of not stopping the vehicle, reducing the number of staff and tightening the internal management. It is usually used for the special lane of Expressway bayonet. Its function is to solve the problem of traffic jam and reduce the operation cost.
自动检测出超速车辆：此项功能适用于在高速公路上，由于车辆的超速而进行监控。通过在路上拍摄到超速的车辆，传到指挥中心进行实时车牌照的识别，以使交管部门做出相应的处罚。
Automatic detection of overspeed vehicles: this function is applicable to the monitoring of overspeed vehicles on highways. By photographing speeding vehicles on the road, they are sent to the command center for real-time license plate recognition, so that the traffic control department can make corresponding punishment.
