The invention relates to the technical field of road indication facilities, in particular to a distributed dynamic monitoring traffic guidance screen control system. According to the invention, a distributed traffic guidance screen control module is established to control a plurality of LED display screens to display signals, so that combined release of dynamic information and static information is carried out. According to the invention, the LED display screen is controlled to display by using an independent control panel, the display and monitoring functions of the LED display screen are increased, meanwhile, only information used for displaying images in signals is intercepted in each display module, the refresh rate and the information updating frequency of the LED display screen are improved, and a dynamic road condition monitoring method based on multi-sensor fusion is established. A corresponding moving vehicle target image is obtained through difference calculation, the road monitoring accuracy and real-time performance of the traffic guidance screen processing system are improved, meanwhile, the light intensity self-adaptive adjustment algorithm is used for systematically sensing different illumination within one day, and the situation that the visual effect of a driver is affected by the brightness factor of an LED display screen is avoided.

    本发明涉及道路指示设施技术领域,具体涉及一种分布式动态监控交通诱导屏控制系统。本发明通过建立分布式交通诱导屏控制模块,控制多块LED显示屏显示信号,进行动态信息与静态信息的组合发布。本发明将LED显示屏使用单独控制板控制显示,增加LED显示屏的显示与监控功能,同时在各显示模块中只截取信号中用于显示图像的信息,提高LED显示屏的刷新率与信息更新频率,并建立了基于多传感器融合的动态路况监测方法,通过差分计算得到对应的运动车辆目标图像,提高了交通诱导屏处理系统对道路监测的准确性与实时性,同时本发明所述的光强自适应调节算法,对一天内不同的光照进行系统性的感知,避免由于LED显示屏的亮度因素影响司机的视觉效果。
