Description
Technical field
The utility model relates to a kind of identification controller, relates in particular to the infrared identification controller of a kind of LED illuminator.
Background technology
In the building intelligent Lighting Control Assembly, need to automatically control, realize the full-automation of building lighting.This just needs system can judge whether voluntarily the people, if the no one, lamp is not opened, if the people is arranged judge the brightness that needs lighting environment, then determines whether thrown light on.Need to realize these functions, just need the identification controller that can realize these judgements, to whether having the information judgements such as people and ambient light intensity then illumination to be controlled.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind ofly can differentiate the infrared identification controller of LED illuminator that whether people, intensity of illumination is arranged and throw light on and control.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
The infrared identification controller of a kind of LED illuminator is characterized in that:
The infrared identification controller of described LED illuminator comprises single-chip microcomputer, passive pyroelectric infrared detector, ambient noise detector, visible-light detector and remote controllers;

Adopt such technical scheme, the infrared identification controller of LED illuminator to whether the people is arranged, need the collection of the information such as ambient lighting intensity of illumination, and calculate judgement by single-chip microcomputer, control building lighting by remote controllers, realize the full-automation of building lighting, improved the building lighting environmental quality.
The accompanying drawing explanation
Fig. 1 is the module circuit diagram of the infrared identification controller of LED illuminator of the present utility model.
Fig. 2 is the control flow chart of the infrared identification controller of LED illuminator of the present utility model.
Embodiment
As shown in Figure 1, the infrared identification controller of LED illuminator of the present utility model comprises single-chip microcomputer, passive pyroelectric infrared detector, ambient noise detector, visible-light detector and remote controllers.Single-chip microcomputer is connected with remote controllers with passive pyroelectric infrared detector, ambient noise detector, visible-light detector, passive pyroelectric infrared detector, ambient noise detector and visible-light detector receive external information and flow to single-chip microcomputer, single-chip microcomputer calculates judgement, and send control information to remote controllers, control building lighting.
Passive infrared detector has three critical elements: (1) Fresnel optical filtering wafer, it,, by the Fresnel optical filtering wafer of cut-off wavelength 8～12 μ m, plays band pass filter, makes the interference of environment be subject to obvious control action.(2) Fresnel Lenses, effect has two: the one, and focussing force, be about to the hot infrared signal refraction of releasing on PIR (pyroelectric infrared sensor), second effect is the variation of infrared energy in surveying security area, and by solidification software in system, gathered data are carried out to computing processing, determine whether sending by control logic the signal of turning on light by the control software in control system.(3) pyroelectric infrared sensor (PIR) will convert the signal of telecommunication to through the variation of the infrared energy of optical filtering wafer, i.e. thermoelectricity conversion.Therefore in the security area of passive infrared detector, when moving without human body, the just ambient temperature that pyroelectric infrared sensor is sensed, when human body enters the people security area, pass through Fresnel Lenses, what pyroelectric infrared sensor was sensed is the difference of human body temperature and ambient temperature, after the collected servo system of signal, the detection data in early stage existed in data and system internal memory by software to this new collection carries out time delay relatively, to judge whether really have the people to wait infrared source to enter security area, or be environmental fluctuating, or even the impact of element self internal noise, to avoid erroneous judgement disconnected.Therefore, infrared acquisition transducing part software and hardware is mainly to change to judge whether that by the acquisition environment infrared ray someone enters the security area that needs illumination.
It is mainly that the noise produced by Human routine activities in acquisition environment is surveyed that ambient noise is surveyed; and carry out exclusive disjunction with the data of infrared ray part in internal system, insensitive and can't determine whether that someone enters the zone that needs illumination with compensation infrared acquisition when ambient temperature very approaches human body.
Visible-light detector compares by the various performances to photodetectors such as photoelectric tube, photo resistance, finds that the peak in the spectral response of photo resistance relatively approaches the wavelength of people's vision sensitizing range.Next is when intensity of illumination weakens, and its response time increases relatively, and device is when intensity of illumination changes, and output state keeps relative stability.
System adopts the core of single-chip microcomputer as illuminator, and the description of single-chip microcomputer is a lot, the principle of choosing be make that system is simple as far as possible, dependable performance, cost be low.We select 8051 single-chip microcomputers of IntEL, and it includes the RAM of 128 bytes, 32 I/o lines, 28 bit timing device/registers that 8 bit constants can be reset automatically.Single-chip microcomputer output pulse can directly be connected to the SCR control utmost point after isolation, power amplification, controls controllable silicon.
Remote controllers, MAX1473 receiver and the MAX1472 transmitter of selecting Maxim to provide, this product work exempts to authorize wave band at 300MHz to 450MHz, and under indoor environment, communication distance can reach 30m to 50m.
As shown in Figure 2, during use, at first by passive pyroelectric infrared detector and ambient noise, survey whether the people is arranged, and by the brightness of visible-light detector acquisition environment.Calculate judgement by single-chip microcomputer, if the no one, the LED lamp is not opened; If someone, be divided into two kinds of situations: (1) is if the illumination X of the environment of needs illuminations > during 200lx, the LED lighting is in closed condition; (2) if, while needing the illumination x of the environment of illumination<200lx, by remote controllers, control the LED lighting in opening.Realize the full-automation of building lighting by such technical scheme, by having judged whether the human and environment brightness, thrown light on and automatically control, improved the quality of building lighting environment.
