一种高清道口智能补光系统设计

设计一种基于快门同步的高清道口智能补光系统。以MSP430F2272微控制器为核心，采集摄像机快门、车检器信号，控制LED灯、爆闪灯与摄像机同步工作。高清道口智能补光系统，既满足车牌识别的补光要求，又满足抓拍车辆前排驾乘人员的要求，同时显著降低功耗，延长了爆闪灯的使用周期。系统可以在Pc控制下工作，也可以在光敏电阻、实时时钟的辅助下，脱机工作。

The Design of Intelligent Lighting Supplement System Used at Grade Crossings

An intelligent lighting supplement system is designed based on high - definition cameras＇ shutter synchronization used at grade crossings. This system mainly takes MSP430F2272 microcontroller as the central controller, collects signals from camera＇s shutter and vehicle detectors, makes LED, flashing lights and camera shutter working synchronously. This system can meet the require- ments of both camera lighting supplement for license plate recognition and taking photographs of drivers, meanwhile, lower the power consumption obviously and expand the usage duration of flashing lights. The system not only can work under control of PC, but also work independently by assistant of photosensitive resistance and real - time clock without PC.
