Description
Technical field
The present invention relates to city illumination technical field, particularly a kind of energy-saving control system for roam lamp.
Background technology
With developing rapidly for urban lighting construction, although urban lighting system is providing convenient life, construction for people
City Easy Living Envi-ronment, but we can not ignore a large amount of electric power resources that it is consumed, in order to alleviate the contradiction of both,
In the evolution of smart city, one kind will be produced and illuminated on demand, the illumination information management system of intelligent management is whole to improving
The bright light rate of city illumination, energy saving, improve the investment climate, reduce traffic accident, guarantee personal safety, stable society public security
Effectively act on etc. playing.
City illumination is the important foundation construction in a city, with the development of urban construction, urban lighting construction
Increasingly pay attention to the image in city, the monitoring degree of city street lamp illumination also becomes one of the important symbol in city.It is anti-
The mental outlook of a modern city is reflected, has been the image representative in a city.Urban public security, urban beautification, night are handed over
Pass to and city civilization construction plays an important role, for city people's lives and economic activity important guarantee is provided.Street lamp control
System operation is what is realized by controlling the power supply to road lamp, and the basic current supply circuit of street lighting is transformer, supplies to match somebody with somebody
, to lamp stand, again to the road lamp on lamp stand, control mode is opening and closing of the control for A.C. contactor in power distribution cabinet for electric cabinet, cable
Realize what switch lamp was controlled.
Street lamp, at night, serves very important effect as the chief component of city lighting engineering.Street lamp is not
Night traffic safety illumination is only provided, the necessary facility of night public security is even more maintained, from the quality of street lamp facility one is can be seen that
The level of individual urban modernization, therefore construction of each city in the world to street lamp facility pay much attention to.With the energy in recent years
Price sharp rises, and huge street lamp electricity charge spending is also born greatly into the one of local government, and short of electricity and illumination backwardness become
The bottleneck of restriction economic development.In recent years, illuminating energy-saving problem is listed in another great saving electricity item in addition to power saving,
This development undoubtedly to promoting energy-saving electricity to work, has very important significance.
City street lamp illumination is requisite communal facility in people's daily life.Street lighting power consumption accounts for total consumption
The 15% of electricity, the various problems that all parts of the country are brought in the face of power tense invariably.In the face of power shortage situation, street lamp inspection is right
It is the work for needing to expend a large amount of manpowers for municipal sector, various temporarily emergent power-saving measures are widely adopted：Night
Night closes Landscape Lighting etc. every the time of road lamp switch of turning off the light, adjust, in the date of shortage of electric power, when peak of power consumption mistake
Afterwards, these measures may just be laid aside and neglected, and the peak of power consumption in next year is arrived, and all can restart again.Such economize on electricity is arranged
Apply, while shortage of electric power is alleviated, but bring the waste and the negative effect to people's daily life of resource.Alleviate electricity consumption tight
Optimal and effective method be that intelligent management is implemented to electricity consumption, reduce and waste, make our every kilowatt-hour can thing it is most
Its use.
For intelligent road lamp system, can accurately judge in dark conditions whether someone is through critically important.
Traditional switch street lamp and acoustic control road lamp system, need manual control to switch or light street lamp by sending certain sound.
For the road lamp system of switch control rule, when pedestrian can not turn off in time after in the past, cause long-time to be lighted, generate waste；
For voice activated control, need just make street lamp point by the behavior such as loudly cough, clap hands, stamping one's foot when in the dead of night
It is bright, noise is produced, have impact on the normal rest of people around, it is seen that both approaches are all very inconvenient, and easily produce behaviour by mistake
Make, so both street lamp control systems can not effectively play a role, it is impossible to realize intelligent.
Mostly using time control or artificial control, this can bring now traditional road lamp switch in actual management process
It is many inconvenient.Due to the uncertainty of external environment, often formed when evening street lamp has already turned on by time control, day
But also do not have black, or early heaven is bright, and street lamp but also opens, and causes serious waste of energy.Sunshine-duration in winter is short, again meeting
Form the black street lamp in day still not open, early heaven does not also have the bright street lamp but to have extinguished, and affects the trip of pedestrian and vehicle.
Existing street lamp does not possess when the function of ponding depth alarm yet, i.e., easily send out place in the first-class unattended water damage of road,
Occur in time notifying that operator on duty removes the dangerous condition when ponding cannot in time discharge accident, report in real time can not be reached well
Alert effect.
