Lane speed limit sign system
The invention relates to a lane speed limit sign system which comprises an LED light panel and an environment illumination detection device. The LED light panel and the environment illumination detection device are embedded into a different lane road surface and are in communication connection with a variable speed limit traffic control system through a signal receiving and transmitting device, and the variable speed limit traffic control system controls the LED light panel to display a corresponding speed limit value. The environment illumination detection device transmits the detected illumination intensity information to the variable speed limit traffic control system so as to control the luminous intensity of the LED light panel according to the illumination intensity information; theLED light panel, the environment illumination detection device and the signal receiving and transmitting device are all connected to the self-checking device and are combined with the variable speed limit control system to monitor whether the three devices work normally or not; and the LED light panel is also connected with an alternating current power supply. Compared with the prior art, the speed limit values of different lanes can be continuously displayed in real time through the LED light panel embedded into the pavements of the different lanes in combination with an existing variable speed limit control system, and a driver can conveniently recognize the speed limit values.
本发明涉及一种车道限速标志系统，包括嵌入安装在不同车道路面的LED灯光板和环境照度检测装置，两者均通过信号收发装置与可变限速交通控制系统通信连接，由可变限速交通控制系统控制LED灯光板显示对应的限速数值；环境照度检测装置将检测的光照强度信息传输给可变限速交通控制系统，以根据光照强度信息控制LED灯光板的发光强度；LED灯光板、环境照度检测装置和信号收发装置均连接至自检装置，结合可变限速控制系统，以监测这三者是否工作正常；LED灯光板还连接有交流电源。与现有技术相比，本发明通过嵌入安装于不同车道路面的LED灯光板，结合现有的可变限速控制系统，能够连续实时显示不同车道的限速值，且便于驾驶者识别。
