Description

A kind of Intelligent corridor lighting system

Technical field

The invention belongs to field of intelligent control, particularly relate to a kind of Intelligent corridor lighting system.

Background technology

It is to adopt switch control that corridor illuminating system starts most, the corresponding hand switch of each corridor lamp, the pedestrian who goes downstairs from above control switch voluntarily.The advantage of this kind of control mode is that stability is higher, can accurately control the switch of single corridor lamp; But this mode needs the own switch of pedestrian, for an opening, dark corridor environment, finding the position of the switch is not sometimes an easy thing, the people who enters especially for the first time this building, known to having no way of especially for the position of the switch; , consider from the angle of energy savings meanwhile, this control mode need pedestrian open and close successively each corridor lamp of process, processing ease makes people's operation of abandoning turning off the light frequently, thereby makes corridor lamp in long-term illuminating state, causes unnecessary waste of energy.

In order to address this is that, on market, start to occur the corridor lamp control system of acousto-optic control control, integrate acoustic control, light-operated, delayed automatic control technology, built-in sound sensing element, light efficiency sensing element, its cardinal principle utilizes sound control circuit and light-operated circuit to control corridor lamp, by day or when light is brighter, control system is closed condition, lamp does not work; When night or light are darker, control system is preparation work state, and when having people through near this switch time, footsteps, voice, clapping etc. can opening control systems; After lamp is bright, automatically close through the delay saving switch of about 40 seconds, lamp goes out; The advantage of this control system is:

(1) adopt single line to come in and go out: can directly substitute former manual switch, separately wiring, is convenient to install;

(2) acoustic control: highly sensitive, footsteps, voice etc. in its vicinity all can be by switch activated;

(3) life-span is long: this control system all adopts contactless element, does not worry useful life;

(4) power consumptive province: control system self power consumption is less than 0.5W.

But also there is following defect in this control system:

(1) need Sound control, and at quiet night, holding for control lamp the sound sending can echo at corridor, can affect the rest of resident family;

(2) for control lamp open the sound sending, tend to all be collected by entire building, thus the lamp of entire building all can hold at the sound, cause unnecessary power wastage;

(3) audio-switch is easily by other sound interference, anti-environmental factor ability.For example: the sound of extraneous non-human generation, such as: automobile sound, noise of firecrackers, tucket etc., all can allow corridor illuminating system open in no one, cause unnecessary power wastage.

At present, on market in the urgent need to a kind ofly do not need Sound control, can carry out as required the lamp Intelligent corridor lighting system going out of turning on light again with a definite target in view.

Summary of the invention

In order to address the above problem, the utility model proposes does not a kind ofly need Sound control, can carry out as required the lamp Intelligent corridor lighting system going out of turning on light again with a definite target in view.

The technical scheme that the utility model adopts is: a kind of Intelligent corridor lighting system, comprising: central control module, human body infrared induction module, ambient light acquisition module and lighting module; Described human body infrared induction module, ambient light acquisition module and lighting module are all connected with described central control module; It is characterized in that: also comprise pedestrian position locating module, described pedestrian position locating module is connected with described central control module, for locating corridor pedestrian's particular location.

As preferably, described central control module is integrated with the two-dimensional digital map in entire building road, this two-dimensional digital map is according to different floors, be divided into some regions, human body infrared induction module is detected to signal framing to this corridor two-dimensional digital map, then, according to the floor position that detects signal and appear at, light the corridor lamp of different floors, when this signal is when the map of this corridor disappears, close corresponding corridor lamp.

As preferably, described human body infrared induction module comprises human body passive infrared probe, Fresnel Lenses and special chip BISS0001, when there being people to appear at its detecting area, human body infrared induction module just can detect signal and signal is passed to central control module.

As preferably, described ambient light acquisition module comprises photosensitive sensing circuit and D/A converter module, photosensitive sensing circuit is for detection of the illumination brightness of corridor, according to photodiode characteristic, while meeting illumination, resistance can obviously reduce, along with the minimizing of luminosity, the principle that the resistance of photodiode can increase gradually, the different magnitudes of voltage (being analog quantity) that so each photodiode dividing potential drop obtains, the analog quantity of their output detected by ADC0809 analog-to-digital conversion, by the IN3 mono-IN7 port of ADC0809 chip, change into digital quantity, D0 mono-D7 is as data-out port, be connected to central processing unit and carry out data processing, then, central processing unit is controlled the quantity of opening the LED lamp in corridor lighting module according to the power of the ambient light collecting, thereby reaches the effect of automatically controlling the light power of corridor lighting according to the bright degree of actual environment.

As preferably, described lighting module comprises LED lamp, energy-conserving and environment-protective.

Compared with prior art, the utlity model has following beneficial effect:

(1) signal being captured according to infrared sensing module by central control module carries out the unlatching of corridor lamp, has avoided the disturb residents generation of event of noise;

(2) accomplished the accuracy of traditional switch control, human-body infrared sensing module can precisely capture the present position of human body, thereby has accomplished point-to-point illumination control, has avoided causing because of acoustic control the state of entire building bright light, stop waste of energy, saved resource;

(3) control the quantity of opening the LED lamp in corridor lighting module by the power of the ambient light that collects, thereby reach the object of automatically controlling corridor brightness level according to environment actual conditions, energy-conserving and environment-protective.
