A kind of intelligent transportation energy-conserving road lamp of self adaptation light intensity
Technical field
The present invention relates to intelligent transportation illuminator, be specifically related to a kind of intelligent transportation energy-conserving road lamp of self adaptation light intensity.
Background technology
Existing traffic lighting device, adopts the set time open the light and fix the street lamp of luminous light intensity usually; There is the problem of waste electric energy, as summer at dusk, when natural daylight light intensity is also enough, clocked flip is luminous, causes energy waste; Also there is the problem that can not change light intensity with surround lighting, as tunnel face street lamp, no matter driver enters tunnel or rolls tunnel away from, because human eye needs the reaction time to light intensity change, driver can produce obvious of short duration vision photoperceptivity and decline; Lack emergency power supply, as crossroad place, when block power-off occurs, illumination cannot be ensured; In open and close process, use contactor break-make, therefore the electric arc of major loop is very large, and contactor useful life is short, maintenance is large; The size adjustment of major loop tandem electric inductance amount is limited, in contactor make and break process, street lamp both end voltage from zero to fixed value, fluorescent tube preheating and cooling procedure short, therefore lamp tube service life shorten.
Summary of the invention
For above-mentioned prior art, the object of the invention is the intelligent transportation energy-conserving road lamp providing a kind of self adaptation light intensity, and it is intended to solve existing traffic lighting device, there is waste of energy, light intensity is excessively bright, excessively dark, can not adaptive environment light light intensity and the technical problem such as the lamp life-span is short.
For achieving the above object, the technical solution used in the present invention is as follows:
An intelligent transportation energy-conserving road lamp for self adaptation light intensity, comprises power line, comprises the energy-saving controller be connected with power line further; The control circuit be connected with energy-saving controller: send analog signal; The self adaptation light intensity street lamp be connected with control circuit: receive and/or send analog signal; Control circuit: receive analog signal.
In such scheme, described energy-saving controller, comprise controller power source switch, and be connected with controller power source switch respectively and the field programmable gate module be electrically connected successively, D/A converter, trigger and thyristor main controller, also change over switch is provided with between described trigger and thyristor main controller, described mains switch and major loop electricity is connected, and described thyristor main controller comprises antiparallel first thyristor and the second thyristor and is connected in major loop.The street lamp life-span is increased by improving power supply supply.
In such scheme, described control circuit, comprises digital signal processing unit: send analog pulse by linking number weighted-voltage D/A converter and/or receive feedback clock by connection mode number converter; Driver: receive analog pulse and send analog signal.
In such scheme, described self adaptation light intensity street lamp, comprises LED: the analog signal receiving driver; Light intensity detector: send analog signal to analog to digital converter.
Beneficial effect of the present invention: provide the illumination of adaptive environment light light intensity; When region power-off occurs, ensure that the street lamp work as usual in crossroad place and/or tunnel; Saves energy; The street lamp life-span is long.

Embodiment
All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Below in conjunction with accompanying drawing, the present invention will be further described:
Fig. 1 is the intelligent transportation energy-conserving road lamp of modular structure schematic diagram of the present invention, a kind of self adaptation light intensity, comprises power line, comprises the energy-saving controller be connected with power line further; The control circuit be connected with energy-saving controller: send analog signal; The self adaptation light intensity street lamp be connected with control circuit: receive and/or send analog signal; Control circuit: receive analog signal.
Embodiment 1
Fig. 2 is energy-saving controller embodiment schematic diagram of the present invention, and by the first thyristor SCR1, the second thyristor SCR2 inverse parallel connection and load in series are on mains supply.Trigger the first thyristor SCR1 when the positive half cycle of mains voltage starts, trigger the second thyristor SCR2 when negative half period starts, the same noncontacting switch of shape, allow frequent operation, without electric arc, the life-span is long.If positive-negative half-cycle triggers the first thyristor SCR1 and the second thyristor SCR2 with same phase shifting angle a, then load voltage effective value can change with a angle, realizes AC voltage adjusting.Field programmable gate module controls trigger realizes the thyristor alternating-current pressure regulation of major loop, completes the change of street lamp alternating voltage from 0% ~ 100%.Utilize self timer of field programmable gate module, by programming, the slow start-up course of stepless boosting, the slow stopped process of stepless step-down can be realized, ensure that filament has enough preheatings and cooling time.In use, by the voltage at field programmable gate module controls street lamp two ends, the artificial level of illumination that street lamp is set can be realized, reached energy-conservation object.
Embodiment 2
When entering tunnel and/or roll tunnel away from, because light intensity detector detects surround lighting very strong (daytime) and/or very weak (night), respectively to digital signal processing unit high input voltage and/or low-voltage, digital signal processing unit is to driver high input voltage and/or low-voltage, and driver adjustment is arranged on the brightness of the self adaptation light intensity street lamp of tunnel face extremely close to surround lighting; In the middle part of two ends, tunnel to tunnel, soft transitions is carried out in the brightness of all self adaptation light intensity street lamps environmentally light, and the street lamp light intensity in whole piece tunnel is being not consistent, and driver does not have strong vision light intensity reacting condition yet, reduces road accident rate.
