Description

Real time fail feedback LED lamplight control system and real-time feedback method
Technical field
The present invention relates to a kind of LED lamplight control system, be related specifically to the lamp light control system that can carry out real-time feedback information.
The invention still further relates to a kind of real-time feedback control method of LED lamplight.
Technical background
Common along with LED illumination, more and more builds, at outside or inside mounted LED lamp tool, thus heighten atmosphere, become the focus at night, reach the object promoting building added value.But LED lamp can be heterochromatic when fault, flicker etc., can produce larger impact to the whole structure of building, the night scene of building is seemed unsightly because of certain bad lamp.Therefore, on market, appearance part possesses the LED lamplight control system of feedback function, can when detecting that light fixture breaks down, by the shielding in effect, light fixture is not worked, thus reaches the object not affecting building integral effect, and be easy to search out of order light fixture.
But this reponse system on market mostly is and detects the electric property of light fixture, thus reach and judge the whether out of order object of light fixture.But some faults of LED lamp can not lead to electric parameter to judge, namely the electric parameter of LED lamp is normal, communication is also normal, but the light sent has not been control system wants LED lamp issued light (colour cast, heterochromatic), thus has an impact to the whole structure of building.
Summary of the invention
The present invention seeks to according to the problems referred to above, in measurement LED lamp electrically and while communications parameter, also by LED lamp send light color detect, thus reach the real only no abnormal situation that breaks down measured LED lamp and send, some the bad lamp making fault detect more precisely avoid pure electric measurement to feed back, detects not problem out.
For completing foregoing invention object, the present invention is achieved in that a kind of LED lamplight control system with real time fail feedback, and it comprises: LED lamp, LED lamplight controller, computer, power supply form; Described power supply is that LED lamp is powered; Described LED lamp receives from LED lamplight controller information, allows the LED on it send corresponding light, and computer provides signal source for LED lamplight controller; It is characterized in that: described LED lamp is made up of LED, LED driver, light source colour transducer, microcontroller (MCU) and color feedback circuit and communication part; Described LED is luminous by LED driver, and microcontroller receives the information of self-controller by communication part; Color feedback circuit and color sensor communication, by microprocessor controls, and feed back to LED lamplight controller by communication part; Both-way communication is carried out between LED lamplight controller and computer.Color sensor be with three phototriodes, add three primary colors filter at phototriode transducing part; Phototriode exports different current strength according to the power of light, rear class adds A/D convertor circuit, imported into light is divided into three primary colors (red, green, blue) the most at last, convert often kind of basic look to digital signal through A/D convertor circuit again to export, this transducer is common in Tansducer For Color Distiguishing, finally encapsulates with the form of IC.
LED lamplight controller can control the color of LED lamp by transmission line, receive the data of LED lamp feedback; And data are saved to computer communication the data that computer or receiving computer send over.LED lamplight controller has memory or plug-in memory.The universal serial bus of the parallel bus that described communication network adopts RS-485 bus to form and use single wire transmission formed, and wherein the universal serial bus of single wire transmission has the ability of transmitted in both directions; Two kinds of buses can be used alone or together use.Described computer and the communication of LED lamplight controller, by LED lamplight controller to LED lamp communication; Receive LED lamp institute feedack to be shown by computer software.
Device of the present invention can sense by the color sensor self installed the light that corresponding LED sends; Thus by the parameter feedback of this color value to LED controller, by the comparison spreading out of numerical value, judge whether the light sent is same color with the color originally determined; Finally send end user to, thus maintenance is entered to LED.This method, can detect LED lamp on the one hand, on the other hand can also be luminous by the corresponding LED of shielding, also avoid the generation of this mistake, and this system has carried out effective location for the position reported an error, reduce detection time and detected artificial input.
Another goal of the invention of the present invention, is to provide a kind of method of real-time detection LED lamp; Come to detect the LED lamp on building by this detection in real time.
For completing foregoing invention object, the present invention is achieved in that a kind of method of Real-time Feedback LED fault, it is characterized in that:
1) LED lamp presets address unique in whole system when mounted, and is kept in MCU;
2) draw the cloth lamp figure having corresponding whole system in a computer, through LED lamplight controller, both-way communication is carried out to each LED lamp by software; Control the parameter of the LED lamp such as the bright color of LED lamp and reading color sensor;
3) in installation, during debugging, by software, control the light of the bright often kind of primary colours of LED lamp, and said the word by computer, the color data that color sensor accepts is demarcated, and as fiducial value; This fiducial value is stored in LED lamp and upper computer software; And pass through the processing mode of the color exception of software design patterns LED lamp;
4) when normally working, computer software, through the effect files preset in LED lamplight controller or LED lamplight controller, carries out the broadcasting of effect; After LED lamp receives corresponding colouring information, show corresponding color; Meanwhile, the microcontroller of LED lamp inside, by the data of color sensor, judges the bright color correctness of LED lamp bead;
5) when LED lamp breaks down, when causing LED lamp bead color exception, the numerical value that microcontroller in LED lamp is transmitted by color sensor, judge color exception, carry out the instruction (effect of turning off the light or setting) of color according to the pattern preset, this abnormal data is sent to LED lamplight controller and computer software simultaneously;
6), as system maintenance personnel, when safeguarding, finding information computer interface having abnormal light fixture, by reading the electric parameter of LED lamp further, thus judging whether LED lamp really occurs exception; If really there is exception, then by the positional information of abnormal light fixture, find the position at abnormal light fixture place accurately, and light fixture is removed maintenance;
7) system maintenance personnel, the color control data of checking each lamp real-time by computer software and color feedback data and relevant electric parameter.
Technique scheme is further improved and limits: when LED lamplight controller and computer software receive this exception, first this abnormal information is preserved, and mask the colouring information of this light fixture when effect is play, thus reach to building overall Night Scenery Effect do not have an impact.
If be because LED lamp is subject to the impact of the random veiling glare of environment and the wrong report that produces, then by Failure elimination on inspection in the 6th step; Also by upper computer software, this abnormal light fixture is demarcated again, to adapt to extraneous new change.
Through the utilization of said method mode, the light sent effectively can be avoided not to be that control system wants LED lamp issued light (colour cast, heterochromatic), thus the whole structure of building is had an impact.
