This system can on the real-time collection basis of the front-end information such as the traffic flow character to the traffic operating mode in weather condition, the luminance of outer caves, tunnel and section and tunnel, in conjunction with the historical data in database, adopt intelligent fuzzy controller, Intelligent management module and adaptive control system, intelligentized real-time decision-making is provided to highway tunnel illumination, reach the object of safety, environmental protection and energy consumption optimum on the whole, fill up the blank of existing tunnel facility in real-time energy source optimization technology.
Lighting loop 103, is connected with operating device 102, receives light modulation instruction, the brightness of adjustment lighting loop, and the brightness of illumination in hole is adapted with the brightness of extraneous natural light.Lighting loop comprises basic illuminating line and strengthens illuminating line; Wherein basic illumination refer to for ensure driving institute in tunnel must illumination, add strong illumination and refer to the illumination required for elimination gangway " white hole " and " black hole " effect. Basic illuminating line in tunnel should lay 3 loops, light fixture is divided into 1A, 1B, 1C staggered access circuit, add strong illumination and should lay 3 loops, light fixture is divided into 2A, 2B, 2C staggered access circuit, the benefit of such wiring is after a distribution line breaks down, the illumination of whole bar branch road can not be affected, but also be conducive to light modulation. Wherein basic illumination refer to for ensure driving institute in tunnel must illumination, add strong illumination and refer to the illumination required for elimination gangway " white hole " and " black hole " effect.
Tunnel Lighting control, it it is the illumination detector by arranging inside and outside tunnel, according to the light intensity inside and outside the tunnel detected, traffic flow and wagon flow speed, after fuzzy operation, control the strengthening segment near gangway, tunnel and adapt to the intensity of illumination of section, after fuzzy operation, the intensity of illumination of section and outlet section in the middle of tunnel is controlled according to traffic flow and wagon flow speed, make officer can adapt to the intensity variation inside and outside tunnel as early as possible, eliminate because of the visual angle obstacle caused by light intensity change, minimizing accident barrier occurs, reduce energy consumption, extend light fixture work-ing life.
The control mode of the tunnel illuminating system of the present invention is divided into sequential control mode that Non-follow control, segmentation carry out and the full automatic control mode three kinds according to the brightness value self-control lighting loop inside and outside hole. Total, tunnel Lighting control carries out stepped control according to weather condition, illumination, speed and volume of traffic stream.
(1) manual control mode
It is divided into local hand control mode and remote manual control mode; Local Non-follow control is realized by the operation button on on-the-spot energy saving control cabinet for lighting, just needs managerial personnel to arrive on-site manual control loop brightness when long-range upper computer or network of communication generation fault. Remote manual controls to realize on lighting system workstation.
(2) subsection timing sequence control mode
Subsection timing sequence control is each light distribution loop adopting sequential control device control tunnel illumination, opens or close corresponding lighting loop according to Different periods in a day.

6, outlet section brightness=5 �� 4.5=22.5cd/m2; Illumination=292.5lx.
The automatic control mode of tunnel illumination is then utilize luminance detector to gather the luminance parameter inside and outside hole, tunnel respectively, after contrast treatment, steering order is issued on energy saving control cabinet for lighting by lighting system workstation, energy-saving control cabinet performs the brightness regulating lighting loop, and the brightness that is bright and extraneous natural light of the illumination in hole is adapted.
In the variable of control automatically, except luminance parameter, also wagon flow amount, the speed of a motor vehicle, VI/CO parameter are incorporated in algorithm model, as the subsidiary conditions generating steering order curve, to reach not only safety but also energy-conservation best effect.
For control with an automatic light meter, the adaptation curve of officer and distance depend on difference and the speed of a motor vehicle of brightness inside and outside hole, generally take a parking sighting distance. Entrance section in tunnel entrances place and tunnel, transition section, outlet section arranges luminance detector, luminance detector sets the road being arranged on from hole, tunnel from as the safe braking distance of scanning frequency degree, namely the brightness in the 200 meters of scopes in distance center, hole, tunnel is measured, entrance section, transition section and the outlet section that remaining luminance detector is arranged on respectively in tunnel, automatically brightness values in the hole detected is sent into workstation and is analyzed by luminance detector, data are after treatment, issue light modulation instruction by workstation, form a closed-loop control. Brightness regulation scope should be provided with the upper limit and lower value, and wherein the lower value of brightness is the minimum brightness value ensureing driving safety, and the higher limit of brightness refers to eliminate " zebra effect ", the minimum brightness value of " black hole effect " and " white hole effect "; When adopting real-time control program photodetector generation fault, after monitor workstation detects trouble signal, activating sequential control strategy, system proceeds to sequential control.
In the variable of control automatically, except luminance parameter, also wagon flow amount, the speed of a motor vehicle, VI/CO parameter are incorporated in algorithm model, as the subsidiary conditions generating steering order curve, to reach not only safety but also energy-conservation best effect.
The automatic control mode of tunnel illumination utilizes luminance detector to gather the luminance parameter inside and outside hole, tunnel respectively, the required brightness value real-time luminosity value of collection and model calculated is after contrasting and carry out PID arithmetic process, steering order is issued on energy saving control cabinet for lighting by lighting system workstation, energy-saving control cabinet performs the brightness regulating lighting loop, and the brightness that is bright and extraneous natural light of the illumination in hole is adapted.
Wherein energy-saving control cabinet is to whole bar illuminating line, employing be the LED power module central current supply supporting hot plug, and reserved redundant power module, when, after certain power supply module damage, redundant power module starts to run automatically, ensures the normal operation of illuminating line. Because support hot plug, also without the need to cutting off the electricity supply when changing module.
