The tunnel lighting control mode reflects the modernization degree of tunnel operation management to a great extent. The tunnel lighting system is provided with a lighting control truss/distribution box, can realize field manual control and automatic control, reserves a remote control module, provides a relay contact for controlling lighting facilities, and directly connects a lighting area control unit with the relay contact of the lighting control cabinet/distribution box so as to realize the remote control of the lighting facilities. The tunnel lighting control modes include the following modes:
1) and (4) manual control. The method is characterized in that tunnel managers manually select a control scheme according to parameters such as luminance outside a tunnel, traffic volume and the like. Specifically, it is based on the luminance L outside the hole20(S), traffic volume, average vehicle speed, weather conditions, and the like. The on/off of the lighting loop is manually controlled by a road tunnel manager or the lighting brightness is steplessly regulated and controlled, and the method can be subdivided into a remote manual control mode and a local manual control mode. The local manual control mode is mostly used for the highway tunnel with short length and simple operation management equipment in the early stage.
2) And (4) an automatic control mode. The method is characterized in that the illumination control system automatically regulates and controls illumination brightness according to parameters such as outdoor brightness and traffic volume collected in real time.
The automatic control of tunnel illumination is realized by using related illumination control parameters collected by a luminance detector, a vehicle detector and other devices and directly using electronic equipmentThe illumination loop is controlled to be switched on/off or illumination brightness is regulated and controlled steplessly without manual participation in the control process, and the control process can be subdivided into a remote automatic control mode and a local automatic control mode. Under the automatic control mode, the tunnel lighting control system saws the acquired outside-hole brightness L of H inches20(S), lighting control parameters such as traffic volume, average speed and the like, and automatically regulating and controlling the lighting brightness in the tunnel; tunnel managers can switch from an automatic control mode to a manual control mode to be manually operated according to actual operation management conditions. The control mode is adopted in the 80 th century abroad, and most highway tunnels in China also adopt an illumination control mode with automatic control as a main mode and manual control as an auxiliary mode.
3) And (4) an intelligent control mode. On the basis of an automatic control mode, the short-term traffic flow prediction theory is adopted, and the dynamic dimming control is carried out according to a decreasing adaptation curve of the illumination brightness of the road tunnel by applying intelligent control technologies such as artificial intelligence, a koch system, fuzzy control, a neural network and a genetic algorithm so as to achieve the safe, comfortable, efficient and economic illumination effect. The mode emphasizes the characteristic of energy-saving control, embodies the requirement of green illumination and pursues an ideal and untried target of 'illumination on demand'. With the improvement of industrial automation level, the development of lighting sources and the improvement of lighting lamps, the intelligent control mode can be more widely applied.
However, there is no solution for the car light in the current lighting optimization, and research and optimization are needed.
