Energy saving device for illuminating vehicle passing through tunnel
Technical field
The present invention relates to a kind of energy-saving control device, relate to a kind of energy saving device for illuminating vehicle passing through tunnel or rather, belong to the control technology field.
Background technology
Freeway tunnel for the driving safety of vehicle, is typically provided with the tunnel illumination system.
Freeway tunnel must reach certain brightness according to different speed of a motor vehicle grade regulation tunnel intraoral illuminations.This is necessary for guaranteeing the vehicle safety process of passing through tunnel.
Because freeway tunnel has enforceable lighting requirement, the electric consumption on lighting expense is always to be the costs on the higher scale expense of freeway tunnel operation.Also owing to the mandatory lighting requirement of freeway tunnel, reach the randomness of vehicle process of passing through tunnel, common lighting energy saving control method just can not be used for illumination of highway tunnel control as controlling brightness of illumination on a time period.
According to the be open to traffic statistics of situation of present highway,, be less than daytime evening greatly by the vehicle number in tunnel.The tunnel, mountain area that has, the vehicle in evening is seldom, and according to Compulsory Feature, no matter how many freeway tunnel vehicles all will guarantee the brightness of illumination in the tunnel.
Therefore, illumination of highway tunnel control power saving just becomes one of concerned issue of each side researcher.
Summary of the invention
The object of the present invention is to provide a kind of illuminating vehicle passing through tunnel energy-saving control method and control device thereof, this control method and device can realize that tunnel illumination system car crosses lamp to the bright car of lamp and go out, and reach saves energy and guarantee vehicle driving safety.
For achieving the above object, technical scheme of the present invention is: at tunnel portal and inner wagon detector and lighting power supply system switch or the lighting brightness controller laid, connect with communication network between the wagon detector.According to the wagon detector testing result, the switch or the brightness degree of control tunnel illuminating lamp, no vehicle is turned off or the brightness reduction through out-of-date tunnel illuminating lamp, has vehicle to recover normal brightness through out-of-date lighting.
Wagon detector can be following kind: 1), induction coil type wagon detector 2), microwave (radar) wagon detector 3), ultra sonic vehicle detector 4), infrared vehicle detector 5), the video frequency vehicle detector.The different detector of above-mentioned various principle all can adopt.The present invention is with 1), induction coil type wagon detector is main the description.
The effect of wagon detector is to detect the vehicle process accurately.
The laying mode of wagon detector in the tunnel is that segmentation along the line is laid at tunnel portal section cloth if in the tunnel.The brilliance control of tunnel intraoral illumination lamp, switch control can be the omnidistance unified control in tunnel, also can segmentation control.
Beneficial effect of the present invention: illuminating vehicle passing through tunnel energy-saving control method and device, remove the tunnel portal section, tunnel intraoral illumination lamp is only opened the brightness of 1/3-1/5 at ordinary times.In case wagon detector detects vehicle, this section of wagon detector D and forward direction 2D section illuminating lamp recover brightness at ordinary times; Vehicle arrives next wagon detector, and this section D and forward direction 2D illuminating lamp are bright, the back segment illuminating lamp extinguishes the brightness to 1/3-1/5, or extinguish the brightness to 1/3-1/5 behind certain hour.The vehicle driver feels it is the tunnel illuminating lamp standard-sized sheet like this, both guaranteed safety, reach energy conservation object again, for differing bigger vcehicular tunnel in volume of traffic daytime and evening, this control mode can significantly reduce the tunnel illumination energy consumption, prolong lamp life, have tangible economic benefit and social benefit.
Below in conjunction with drawings and Examples to the present invention's detailed explanation of making comparisons.

Embodiment
With reference to Fig. 1, tunnel illumination vehicle pass-through energy-saving control device block diagram of the present invention.
Be coil form wagon detector theory diagram as Figure 1-1; Be depicted as brightness of illumination Principles of Regulation block diagram as Fig. 1-2.
Control device is included in tunnel portal or the inner wagon detector of laying, and switch and brightness controller in that illuminator is provided with connect with communication network between the wagon detector.Wagon detector does not detect signal when having vehicle pass-through in the tunnel, and tunnel portal section illuminating lamp is often to open, and internal link is to close or brightness is turned down; When vehicle process of passing through tunnel inlet wagon detector is arranged in the tunnel, trigger control appliance and the illuminating lamp of vehicle leading portion is opened bright entirely.
With reference to Fig. 2, this is vehicle of the present invention illuminating position schematic diagram when entering the tunnel.Wherein 1 is that control unit, 2 is that light distribution switch cubicle, 3 is wagon detector.
When vehicle process of passing through tunnel inlet wagon detector, trigger control appliance with vehicle before the illuminating lamp of 2D section open bright entirely.
With reference to Fig. 3, this is tunnel illumination situation vehicle of the present invention schematic diagram when entering the tunnel and advancing.
The expression vehicle enters the tunnel and arrives next wagon detector place, and the lighting at 1D and preceding 2D section place is opened before the vehicle.
With reference to Fig. 4, this is tunnel illumination situation vehicle of the present invention schematic diagram when entering the tunnel and advancing.
Vehicle enters into tunnel portal and plays the 3rd wagon detector place, and 1D section and preceding 2D section illuminating lamp are opened brightly entirely before the vehicle, and the illuminating lamp behind the vehicle except that entrance is turned off or reduced brightness.
With reference to Fig. 5, when vehicle continued to go, 1D section and preceding 2D section illuminating lamp were opened brightly entirely before the vehicle, and the illuminating lamp behind the vehicle except that entrance is turned off or reduced brightness.
About 100 to 200 meters of the length of above-mentioned D, light fixture control is carried out by PLC, RTU or dedicated control circuit.
Present tunnel illumination high-pressure sodium lamp commonly used, because its starting characteristic has than long time delay, inapplicable completely open and close mode is controlled, a useful luminance regulative mode control; Starting characteristic is light fixture such as electrodeless lamp or fluorescent lamp preferably, can adopt the completely open and close mode to control.
Though the present invention describes with reference to the above embodiments; but those of ordinary skill in the art; will be appreciated that above embodiment is used for illustrating the present invention; should understand and wherein can make variations and modifications and do not break away from the present invention in a broad sense; so be not as limitation of the invention; as long as in connotation scope of the present invention, to the variation of above-described embodiment, the protection range that distortion all will fall into claim of the present invention.
