一种适应能见度的动态交通标志牌
摘要：
本发明公开了一种适应能见度的动态交通标志牌包括：主控模块、能见度检测模块、参数调整模块、通信模块、存储模块、LED显示屏和电源模块；能见度检测模块用于检测实时能见度信息，并将其传输至主控模块和参数调整模块；参数调整模块根据实时能见度信息，从预设数据库中获取对应的LED显示屏亮度和显示文字的大小、颜色，并传输至主控模块；主控模块通过内置的监控软件系统将发布的信息按上述参数指标进行调整，并输出相应的输出信号至LED显示屏。本发明可以根据检测到的大气能见度信息完成对LED显示屏亮度和显示文字的大小、颜色的调节，提高低能见度情况下驾驶员对交通标志牌内容的识认性，提高驾驶安全性。
摘要（英）：

The invention discloses a dynamic traffic signboard adapting to the visibility.The dynamic traffic signboard comprises a master control module, a visibility detection module, a parameter adjusting module, a communication module, a storage module, an LED display screen and a power supply module.The visibility detection module is used for detecting real-time visibility information and transmitting the information to the master control module and the parameter adjusting module.The parameter adjusting module obtains corresponding LED display screen brightness and sizes and colors of displayed texts from a preset database according to the real-time visibility information and transmitting the obtained information to the master control module.The master control module adjusts issued information through a built-in monitoring software system according to parameter indexes and outputting corresponding output signals to the LED display screen.The dynamic traffic signboard can complete adjustment of the LED display screen brightness and the sizes and colors of the displayed texts according to the detected atmospheric visibility information, improve the cognition of drivers to contents of the traffic signboard under the situation of low visibility and improve the driving safety.
