Background technology
More and more universal along with issuing the application of diode, and the application of diode is limited only to illumination at present and uses, the light to diode is not sent a telegraph principle and is developed and utilized, and current 2 illuminators cannot be carried out communication.
Summary of the invention
It is an object of the invention to provide the illuminator and detection method thereof that can communicate with one another so that 2 use the illuminator energy intercommunication that LED lighting system becomes, and can detect whether that object is through illuminator.
The present invention is achieved through the following technical solutions:
The illuminator that can communicate with one another, including multiple illuminators, described illuminator includes LED lighting body, diode drive circuit, off state observation circuit, analyzes circuit, communication control circuit；
Diode drive circuit: for exporting the driving signal S1 of height alternating signal, diode current flow under high level state, diode turns off under low level；
Off state observation circuit: under diode off state, monitoring due to light send a telegraph principle produce signal S, signal S include signal SModulationWith signal S3,
Signal S3: have object when LED lighting body photic electric induction interface or without object when LED lighting body photic electric induction interface, send a telegraph due to light principle produce signal,
Signal SModulation: under diode off state, monitor the signal that other LED lighting body exports the light wave being loaded with modulated signal, sends a telegraph principle generation due to light；

Aggregate signal S2 includes aggregate signal SThere is thingWith aggregate signal SEmpty；
Aggregate signal SThere is thing: there is object when LED lighting body photic electric induction interface, under diode off state, send a telegraph, due to light, multiple demarcation signal S that principle producesThere is thing, by multiple demarcation signal SThere is thingSet forms aggregate signal SThere is thing；
Aggregate signal SEmpty: there is no object when LED lighting body photic electric induction interface, under diode off state, send a telegraph, due to light, multiple demarcation signal S that principle producesEmpty, by multiple demarcation signal SEmptySet forms aggregate signal SEmpty；
Use aggregate signal S2 and signal S3 to carry out fuzzy matching, when signal S3 fuzzy matching to aggregate signal SThere is thingIn certain value immediate time, then there is thing information at output diode luminous body photic electric induction interface, signal S3 fuzzy matching to aggregate signal SEmptyIn certain value immediate time, then output diode luminous body photic electric induction interface empty information；

The design principle of the present invention is: the principle that LED lighting body is converted to luminous energy mainly by electric energy realizes illumination, photoelectric characteristic due to diode, diode also can produce electric current under illumination condition, and therefore, the present invention mainly utilizes the light of diode to send a telegraph principle.Owing to the power supply of LED lighting body typically uses the height alternating signal of hyperfrequency；Therefore, the present invention can be by the power supply of collection LED lighting body signal under low level zone state, i.e. send a telegraph, due to light, the signal S that principle produces under monitoring diode off state, when diode off state, under illumination condition, diode can produce the signal of telecommunication, and the general signal gathered is to drive, with LED lighting body, the signal of telecommunication that power supply is contrary, after obtaining signal S3, owing to aggregate signal S2 includes aggregate signal SThere is thingWith aggregate signal SEmpty, due to aggregate signal SThere is thingIt is when there being object to be positioned at LED lighting body photic electric induction interface (lower section), under diode off state, sends a telegraph, due to light, multiple demarcation signal S that principle producesThere is thing, therefore aggregate signal SThere is thingRepresent LED lighting body photic electric induction interface and there is object；Due to aggregate signal SEmptyIt is when there being object to be not at LED lighting body photic electric induction interface, under diode off state, sends a telegraph, due to light, multiple demarcation signal S that principle producesEmpty, therefore aggregate signal SEmptyRepresent LED lighting body photic electric induction interface and there is not object；At this moment, the above-mentioned aggregate signal S2 for contrast is prestored in advance due to us, therefore, we have only to the contrast aggregate signal S2 and signal S3 of obfuscation, find out in aggregate signal S2 immediate signal compared with signal S3, can be by judging the state of this immediate signal, final analysis goes out whether signal S3 correspondence LED lighting body photic electric induction interface has object.Such as, it will be assumed that aggregate signal SThere is thingIt is the alternating signal of 0.5V for high level, aggregate signal SEmptyBe the alternating signal of 1V for high level, and the signal S3 that we record is high level be the alternating signal of 0.7V, signal S3 respectively with aggregate signal SThere is thingWith aggregate signal SEmptyAfter Bi compare, aggregate signal SThere is thingFor immediate signal, accordingly, because aggregate signal SThere is thingRepresenting LED lighting body photic electric induction interface and have object, we pass through aggregate signal SThere is thingJudge that signal S3 represents current light emitting diode light and sends a telegraph sensing interface and there is object.It addition, when receiving signal SModulationAfter, analyzing circuit can be to signal SModulationIt is demodulated, the signal S after final output demodulationDemodulation。
When communication control circuit receives signal SDemodulationOr after there is thing information at LED lighting body photic electric induction interface, communication control circuit output modulated signal is to drive circuit, modulated signal is modulated formation modulated signal on the driving signal of self and is exported and drive LED lighting body, so that 2 illuminators can interact with each other information by drive circuit.
Generally speaking, when the first illuminator has detected object by said structure and mode, this structure can be by analyzing circuit output result, can also be processed by communication control circuit simultaneously, use modulation system to driving signal (carrier wave) to be modulated a modulated signal, show that this device has detected object, now, this illuminator can send due to modulated light wave, principle is sent a telegraph according to light, second illuminator can be affected by modulated light wave, and we are by detection, can obtain receiving signal SModulation, by the analysis circuit realiration of the second illuminator to signal SModulationDemodulation, second illuminator is understood, and the first illuminator has been detected by object, second illuminator is also according to the result of demodulation simultaneously, make the second illuminator load-modulate signal to the driving signal of the second illuminator, form modulated signal, ultimately form the output of modulated light wave, and next illuminator then repeats the action of the second illuminator, thus forms the communication between illuminator.
Preferably, the plurality of demarcation signal SThere is thingIncluding different characteristic object by sending a telegraph, due to light, multiple demarcation signals that principle produces under LED lighting body and diode off state.
