Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings:
The present invention provides a kind of tunnel illumination to adjust light management system, can be according to tunnel by this tunnel illumination tune light management systemSituation outside interior situation and tunnel, adjusts accordingly light intensity in tunnel at any time, thus UV light change in reducing tunnelImpact on driver, and the use minimizing energy waste of the corresponding energy can be reduced.
As an embodiment of the present invention, the present invention provides a kind of tunnel illumination to adjust light management system, including control system,Illuminator 2 ', tunnel inner sensor system 3 ', tunnel outer sensor system 4 ', described illuminator 2 ' is arranged on tunnel 1 'Top, described tunnel inner sensor system 3 ' is embedded in the lower section on ground in tunnel 1 ', and described tunnel outer sensor system 4 ' is divided intoTwo groups are separately positioned on outlet two ends, tunnel 1 ' and include control with tunnel 1 ' port distance at a distance of L rice, L >=1 meter, described control systemTerminal 1 processed, wireless router 2 and serial server 3, described illuminator 2 ' includes wireless aps node 4, dimmer 8 and light modulationLED 9, described dimmer 8 connects dimming LED lamp 9 by connecting line, and each dimmer 8 is corresponding controls 4-8 small cup dimming LED lamp 9,Dimmer of the present invention can control multiple dimming LED lamp, and concrete control is several can be selected according to practical situation, described tunnelInner sensor system 3 ' includes in tunnel illuminance sensor 6-1, described tunnel outer sensor in road conditions sensor 5-1 and tunnelSystem 4 ' includes outside tunnel illuminance sensor 6-2 and photoelectric sensor 7, described tunnel Nei Lu outside road conditions sensor 5-2, tunnelOutside condition sensor 5-1 and tunnel, the road conditions sensor of road conditions sensor 5-2 uses non-contact type road conditions sensor, road conditions sensorEffect be detection road surface freeze, the situation such as accumulated snow and hydrops uploading in real time, use the non-contact type road conditions sensor canTo reduce sensor abrasion, in described tunnel, outside road conditions sensor 5-1, tunnel, in road conditions sensor 5-2, tunnel, illuminance sensesOutside device 6-1, tunnel, illuminance sensor 6-2, photoelectric sensor 7 and dimmer 8 receive serial server 3 by RS-485 busAnd carrying out data exchange via wireless router 2 and serial server 3, control signal is issued to adjust by RS-485 bus simultaneouslyLight device carries out brightness adjustment control, and described dimmer 8 is internally embedded WIFI networking module by wireless aps node 4 and wireless router 2Directly carrying out communication, both sides, described tunnel 1 ' port is respectively arranged with a display lamp 5 ', and described display lamp 5 ' is connect by RS-485 busTo serial server 3, display lamp is set and can be easy to situation in outside display tunnel.
Fig. 1 of the present invention is that tunnel illumination dims management system network topological diagram, and system is by terminal server, wireless routingDevice, serial server, AP node, illuminance sensor, photoelectric sensor, non-contact type road conditions sensor, dimmer form.LightIlluminance transducer, photoelectric sensor, non-contact type road conditions sensor and dimmer receive serial port service by RS-485 busDevice, then carry out data exchange via router and server, control signal is issued to dimmer by RS-485 bus simultaneously, entersRow brightness adjustment control.Dimmer internal embeds WIFI networking module, can pass through AP node and wireless router, directly lead toNews, it is achieved uploading of data, and the acceptance of control command.Be combined with WIFI wireless telecommunications by RS-485 bus communication, compositionDuplex system, forms dual redundant, it is ensured that the stability of system.Illuminance sensor, photoelectric sensor and dimmer are followedModbus puppy parc, facilitates the expansion of system system later to melt.
Fig. 2 of the present invention is illuminator dimming LED lamp structure, and every dimmer can control four to eight LED.AdoptWith pwm control signal, LED is carried out brightness regulation, it is achieved non-pole light regulating.
Fig. 3 of the present invention is tunnel illuminating system functional diagram, at a certain distance from distance tunnel face (determine according to practical situation,Some factors such as including tunnel speed limit) it is provided with tunnel outer sensing system, this system includes illuminance sensor, photoelectric sensingDevice and non-contact type road conditions sensor etc., be provided with internal sensor system, including illuminance sensor, non-contact type in tunnelRoad conditions sensor.Illuminance sensor system can gather the external world and the illuminance value of tunnel internal diverse location, and sends in real timeTo server end, the effect of Electro-Optic Sensor System is collecting vehicle flow and by situation be sent to server end, road in timeThe effect of condition sensor is the situations such as detection road surface icing, accumulated snow and hydrops and uploads in real time.Server receive above respectivelyAfter the information that acquisition module collection comes up, founding mathematical models, according to concrete road conditions, weather, light situation and wagon flowThe information such as amount, the brightness of diverse location lamp in setting tunnel in real time, and tunnel face LED status.Meanwhile, Upper system is worked asWhen causing transmission control to go wrong due to various uncontrollable factors, dimmer can automatically switch into local control.
Fig. 4 of the present invention is that tunnel dims lighting curve figure, and 1 class curve is the ambient light illumination several feelings higher than appropriate illuminationCondition, 2 class curves are the ambient light illumination several situations less than the suitableeest illumination.Server of the present invention sets up mathematics according to collection informationAfter model, illuminator is controlled, closer to tunnel outer, the illuminance in tunnel closer to outside illuminance, withCar constantly deeply, illuminance is gradually adjusted to be best suitable for a brightness of eye-observation；In like manner, tunneling process is outputed when carAlso it is so, by being best suitable for the illumination of eye-observation, gradually adjusts, until closest to ambient light illumination.Driver is from entering tunnelRoad is to leaving tunnel, and illuminance all gradually changes, to adapt to the observation of human eye, it is to avoid by highlighted environment enter low-light environment withAnd being entered the visual inadaptable of highlighted environment appearance by low-light environment, the traffic information simultaneously arrived when collection of server is abnormalTime, the display lamp of tunnel face can be automatically controlled, remind the traffic information of driver's Tunnel ahead, in order to driver makes instead in advanceShould.
The above, be only presently preferred embodiments of the present invention, is not the limit that the present invention makees any other formSystem, and any amendment made according to the technical spirit of the present invention or equivalent variations, still fall within present invention model required for protectionEnclose.
