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 requirements 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.
