For control information is transmitted in power line effectively, the utility model has adopted following two implementation methods that control signal is attached in the alternating current.By alternating current control signal is sent out, reach the purpose that power supply and control information transmit simultaneously.
Implementation method one:
Signal produces:
This multichannel illumination control apparatus is to have changed the method in the zero-crossing of alternating current time interval by on-off controller to come transmission information.On-off controller changes the zero-crossing timing interval of alternating current according to the control data that will send, and forms information flow and sends.Realize the transmission of data.
By artificial change zero-crossing timing interval, allow time interval value after changing and original spacing value have larger difference to come the existence of characterization information.On-off controller in the utility model can be controlled the break-make of alternating current, during photos and sending messages, disconnects alternating current, produces a voltage and be 0 volt state, zero crossing t2 of artificial generation, and the duration is 1/15th of usual zero-crossing timing interval.In the present invention, the moment that disconnects alternating current is selected in the peak value place of alternation, and time interval of the zero crossing of new generation and former zero-crossing of alternating current is only had about original half.Just directly allow alternating current pass through when not sending information.
The zero-crossing timing that the utility model is established the half period of normal alternating current is spaced apart t1, in the time will transmitting information, just produces new zero crossing, and half is shortened in the zero passage interval, is made as t0.
In the agreement communication protocol in this illumination control apparatus, definition t0 is that data 0, definition t1 are data 1, certainly can be t0, and the definition of t1 is arranged conversely.
Signal receives:
In this illumination control apparatus, lamp controller can be finished the detection of signal and control, inner zero cross detection circuit can alternating current voltage be zero state-detection out, be commonly called as zero passage detection.Detection signal is delivered to single-chip microcomputer, by software programming to the received signal, according to the method that the signal of implementation method one produces, judges the time interval of zero cross signal, demodulates the existence of information, demodulates 0 and 1 according to communication protocol again.
Implementation method two:
Signal produces:
By the zero crossing of zero crossing circuitry detection alternating current, the duration of zero crossing is very short usually.This illumination control apparatus is by the existence of the duration characterization information of change zero passage.On-off controller changes the zero passage duration of alternating current according to the control data that will send, and forms information flow and sends.Realize the transmission of data.
Per half period of alternating current produces a zero crossing when normal, and the zero-crossing timing that zero crossing circuitry detects continues very short, is made as t1, in the time will transmitting information, the zero passage duration is elongated, and duration is 1/3rd of the half period, is made as t0.
In the agreement communication protocol in this illumination control apparatus, definition t0 is that data 0, definition t1 are data 1, certainly can be t0, and the definition of t1 is arranged conversely.
On-off controller can be controlled the break-make of alternating current, and during photos and sending messages, the on-off controller that passes through that AC energy is complete does not provide electric power to lighting.
When the transmission data were 0 information, on-off controller turn-offed alternating current when alternating current is in zero crossing, allowed power line cut off the power supply, duration t0, and then connect, the artificial alternating current zero passage duration that makes is elongated, when the transmission data are 1 information, just allow alternating current direct connect.
Signal receives:
In this illumination control apparatus, lamp controller can be finished the detection of signal and control, inner zero cross detection circuit can alternating current voltage be zero state-detection out, be commonly called as zero passage detection.Detection signal is delivered to single-chip microcomputer, by software programming to the received signal, according to the method that the signal of implementation method two produces, judges the duration length of zero cross signal, demodulates the existence of information, demodulates 0 and 1 according to communication protocol again.
With embodiment one course of work of the present invention is described:
Described on-off controller, operate generation light fixture control signal according to the user, the light fixture control signal is on-off controller communication means according to a preconcerted arrangement and one group of light fixture control coding of agreement generation, and coding comprises light on and off and the address information of light fixture by 0 and 1 data sequence that forms in the coding.
Described on-off controller control alternating current break-make is according to the control data sequence that will send, and is corresponding at the voltage peak place of alternating current, disconnects moment of alternating current, produce new zero crossing, realize that stacked data is added on the alternating current, and send out by power line, form information flow.
Described lamp controller can detect and receive the zero cross signal of the inclusion information stream that transmits from power line, restore lamp control signal by decoding, demodulate corresponding light fixture control coding according to the communication means of making an appointment and agreement product, and whether the address in the analysis of encoding is identical with the set address of oneself.Identical person just controls the light on and off of this light fixture.
It should be noted that at last: obviously, above-described embodiment only is for example of the present invention clearly is described, and is not the restriction to execution mode.For those of ordinary skill in the field, slightly make an amendment on the basis of the above description to make other changes in different forms and realize communication, as calculating zero passage number of times, the method for zero-crossing pulse position etc.Here need not also can't give all execution modes exhaustive.And the apparent variation of being extended out thus or change still are among protection scope of the present invention.
