Background technology

Street lamp is the chief component of city illumination engineering, but street lamp is when playing an important role, and is also consuming a large amount of energy.In a city, except major trunk roads, also have arterial highway and little highway section many times, these streets are all smaller at the flow of the people and the vehicle flowrate at night.Particularly some suburbs and remoter highway section, after 1 o'clock of midnight, flow of the people and vehicle flowrate are generally considerably less.But even without people or car process, these street lamps also are to be in illuminating state always, and at this moment electric energy has just been wasted.The real effectively lighting hours in a lot of highway sections only accounts for the 20%-30% of whole lighting hours, that is to say that most of electric energy has been wasted.

At present, the main power-saving technology of street lamp has LED street lamp, solar LED street lamp.Wherein, the LED illumination is a kind of newer technology, and it has advantages such as efficient height, long service life.A LED street lamp if reach and common high-pressure sodium lamp and the such brightness of high-pressure mercury-vapor lamp, approximately needs the above power consumption of 40W of consumption, has only the 25%-40% of conventional road lamp.Along with the development of technology, LED has begun to replace incandescent lamp gradually, is widely used in the various illuminations, and the LED street lamp begins to have tried out in some big cities at present.But the LED street lamp has only improved the conversion efficiency of electric energy to luminous energy, and it is the same with conventional road lamp, still has the not high problem of integral illumination efficient; Solar LED street lamp utilizes the solar energy accumulators to charge by day, utilizes the illumination of storage battery driving LED lamp evening.Though this mode does not need Alternating Current Power Supply, shortcomings such as it exists the cost height, power is little, maintenance is big, battery life is short, poor reliability.Use solar energy fully, can cause the problem that street lamp can't use under the certain situation, so can not be used widely.Also have some cities night in order to save the electric energy that street lighting uses, the mode of illumination at interval of having sampled is promptly just closed one every a street lamp, just closes the street lamp of half.Can save the power consumption of half although it is so, but also bring many hidden danger, reduce, have the illumination dead angle, cause traffic accident easily as brightness of illumination.Simultaneously, still there is the problem of energy waste in the street lamp of half in addition, the inreal problem of energy saving that solves.

Summary of the invention

Defective or deficiency at above-mentioned prior art existence, the purpose of this utility model is, a kind of energy-conserving road lamp control device is provided, this energy-conserving road lamp control device is measured the ambient conditions in highway section, each LED street lamp below by multiple sensors, controls the LED street lamp in this each highway section, street by the microprocessor in every street, and communicates by letter with control centre by wireless transport module, can effectively carry out Energy Saving Control to city LED street lamp, the energy-saving efficiency height, and simple in structure, easy to implement.

In order to realize above-mentioned task, the utility model adopts following technical scheme:

A kind of energy-conserving road lamp control device, comprise a plurality of sensor groups, a plurality of microprocessor and a plurality of wireless transport module, wherein, the number of described sensor groups is identical with the number of LED lamp, and the number of described microprocessor and the wireless transport module all number with the street is identical; Each sensor groups correspondence is installed on the LED street lamp, every street microprocessor of configuration and a coupled wireless transport module; The sensor groups of installing on each LED street lamp and this LED street lamp all is connected with the microprocessor in this LED street lamp place street; Wireless transport module and control centre pass through communicating wireless signals.

The utility model also comprises following other technologies feature:

Described microprocessor adopts the MC9S08QE64 single-chip microcomputer.

Advantage of the present invention:

1, fast with the control signal of road lamp switch from each node that control centre sends to whole street lamp illumination system, can realize the accurate control of each street lamp.

2, the situation with a highway section people and vehicle is delivered to next highway section, can notify next highway section to light street lamp in advance.

3, the maintainer can just can check the working condition and the historical working condition of each street lamp rapidly to the maintenance and inspection one by one of each street lamp in Surveillance center by the Zigbee module.And utilize the transducer that has in the LED street lamp to detect in real time, can carry out fault pre-alarming, in time notice is safeguarded.
