Tunnel reinforcing section illumination control system and method based on vehicle real-time position monitoring

Abstract

The invention discloses a tunnel reinforcing section illumination control system and method based on vehicle real-time position monitoring. The system is characterized in that a brightness informationacquisition unit acquires the brightness information outside a tunnel; a vehicle information acquisition unit acquires the vehicle speed information, the traffic volume and the vehicle position information; a fuzzy logic calculation module calculates an illumination intensity level of a tunnel reinforcing section according to the vehicle speed information, the traffic volume and the brightness information; a control center generates a corresponding dimming instruction according to the vehicle position information and the illumination intensity level of the tunnel reinforcing section, a dimming control center issues a specific dimming level and the dimming loop information to a corresponding dimming controller, and the dimming controller converts the corresponding instruction into a corresponding pulse signal to adjust an illumination level of lamps controlled by the dimming controller. The control system is advantaged in that the lamp brightness within the vehicle sight distance rangecan be accurately adjusted and controlled according to the vehicle position, the control method can improve pertinence and accuracy of illumination on the premise that tunnel driving safety is guaranteed, and the purpose of sufficient energy saving is achieved.

Description

technical field [0001] The invention relates to the technical field of tunnel lighting, in particular to a tunnel reinforcement section lighting control system and method based on real-time vehicle position monitoring. Background technique [0002] The tunnel lighting system is of great significance to ensure the safety and smoothness of tunnel traffic. In the process of highway operation, lighting power consumption is an important part of operating expenses. According to literature [1] (Detailed Rules for Highway Tunnel Lighting, JTG / T D70 / 2-01-2014), one-way traffic tunnel lighting can be divided into five sections in the direction of driving: approach section, tunnel entrance section, transition section, middle section section and the exit section of the tunnel, in which the lighting in the middle section is not affected by the brightness outside the tunnel, while the lighting brightness in the entrance, transition and exit sections of the tunnel is affected by the bright...

Problems solved by technology

Although the above-mentioned methods can achieve energy-saving effects to varying degrees, their brightness control methods still cannot adjust the lighting brightness in time, and cannot achieve a good energy-saving effect.
