A Tunnel Lighting Control System with Dynamic Configuration of Lighting Segment Structure

Abstract

The invention discloses a tunnel lighting control system with dynamic configuration of lighting segment structures. It is composed of lighting group in the tunnel, stepless dimming controller, vehicle detector, illuminance meter, and host computer. The lighting group in the tunnel is divided into the lighting group in the entrance section, the lighting group in the dynamic configuration section, the lighting group in the middle section and the lamps in the exit section. The lamps in the group of lamps in the dynamic configuration section are controlled independently by a single lamp. The host computer adjusts the brightness of different lamps in the group of lamps in the dynamic configuration section according to the ambient brightness and traffic flow outside the tunnel, so as to realize the control of the length of each lighting section in the tunnel. and dynamic configuration of brightness. The invention realizes the smooth transition of lighting brightness in tunnel lighting, solves the problem of human eye discomfort caused by sudden changes in brightness, realizes on-demand lighting at the same time, improves the energy saving, safety and comfort of tunnel operation, and can be widely used In the field of tunnel lighting control such as urban road tunnels and highway tunnels, it is especially suitable for extra-long tunnels and continuous tunnel groups in mountainous areas.

Description

technical field [0001] The invention relates to a tunnel lighting control system, in particular to a tunnel lighting control system with dynamic configuration of lighting segment structures. Background technique [0002] With the development of economy and society, highways have become one of the most important transportation carriers for people to travel. During the construction process, more and more attention is paid to safety, comfort and convenience. In mountainous areas, excavating tunnels can effectively reduce the driving mileage of highways, especially expressways, reduce damage to the surrounding environment, and improve driving safety and comfort. In order to ensure the normal operation of the tunnel, it is often necessary to use a variety of electromechanical systems, including lighting control systems, emergency alarm systems, ventilation control systems, fire protection systems, monitoring systems, etc., among which the lighting control system is the most basic...

Problems solved by technology

[0005] However, there are still some deficiencies in the above-mentioned improvement method: during the construction of the tunnel, the length of each lighting section is generally selected according to the maximum design value, but in the actual operation process, the environmental conditions and traffic flow around the tunnel have obvious time-varying characteristics, resulting in the entrance section There are redundant or insufficient lengths of the transition section and the length of the transition section, which restricts the energy saving and safety of the tunnel; The design of the transition section generally adopts the method of multi-level segmental lighting. Due to the limited number of segments, there is still a sudden change in brightness between adjacent lighting segments; although the stepless dimming control system can dynamically adjust the brightness of the lighting fixtures in the tunnel to reduce the Low energy consumption, but the length of each lighting section cannot be adjusted, especially for the entrance section, due to the high brightness of the lamps, the waste of energy consumption due to redundant lengths cannot be ignored
