The invention discloses an intelligent variable sign system suitable for a highway tunnel and a working method of the intelligent variable sign system. The intelligent variable sign system comprises an illuminance sensor, a first wireless connection point, a visibility sensor, a second wireless connection point, a microwave vehicle detector, a third wireless connection point, a fourth wireless connection point, a data switch, a screen brightness instrument, a data storage server, a variable sign display system and a variable sign cleaning system. According to the invention, a plurality of dataacquisition sensors are added, and the brightness and chromaticity of the display screen of the variable sign system are adjusted by analyzing, processing and comprehensively evaluating the real-timeacquired data, so that the adaptability is improved; graded cleaning is carried out on the variable sign system display screens with different pollution degrees, so that the cleanliness of the display screens is improved; when no vehicle passes through part of road sections or part of time periods, the intelligent variable sign system enters a dormant state, and energy consumption is reduced.

    本发明公开了一种适用于公路隧道的智能可变标志系统及其工作方法,智能可变标志系统包括照度传感器、第一无线连接点、能见度传感器、第二无线连接点、微波车检器、第三无线连接点、第四无线连接点、数据交换机、屏幕亮度仪、数据存储服务器、可变标志显示系统和可变标志清洁系统。本发明增加了多种数据采集传感器,通过对实时采集数据的分析、处理和综合评定,对可变标志系统显示屏幕的亮度和色度进行调整,提高了适应性;对不同污染程度的可变标志系统显示屏幕进行分级清理,提高了显示屏幕的清洁度;当部分路段或者部分时段没有车辆经过时,智能可变标志系统进入休眠状态,降低了能耗。
