When Lamp with ceiling fan wall control unit needs a transmission Lamp with ceiling fan control signal, the waveform of a Lamp with ceiling fan control signal forms by guiding waveform+data waveform; Guide waveform by the negative half-wave of a not conducting, all wave components of an immediately complete conducting; Guiding waveform also can by the complete cycle of a not conducting, all wave components of an immediately complete conducting.
6 continuous half-wave waveforms that data waveform is formed by phase-shifting trigger form, the phase shifting angle of each half-wave can be respectively one in phase shifting angle α 1, α 0, phase shifting angle α 1, α 0 be corresponding binary number code value 1,0 respectively, and 6 continuous half-waves send 6 binary system Lamp with ceiling fan data altogether.First 3 of 6 binary system Lamp with ceiling fan data is address code, and 000,001,010,011,100,101,110,111 of address code represents 1-8 # Lamp with ceiling fan driver element respectively, and therefore, the utility model can control 8 Lamp with ceiling fan at most simultaneously; Rear 3 binary system Lamp with ceiling fan data are control codes 000,001,010,011,100,101,110,111, corresponding with state 1 to the state 8 of Lamp with ceiling fan combined running state respectively.

When single fire wire output end AC1 exports continuous whole single-phase sine wave, the voltage difference between single fire wire output end AC1 and single live wire input AC is very little, and zero passage detection module does not export zero cross signal, and zero cross signal is maintained low level state.
When single chip control module needs a transmission Lamp with ceiling fan control signal, first send guiding waveform, method comprises: the random triggering signal that stops exports; Time during stopping being engraved in AC power positive half wave when exporting triggering signal, this positive half wave bidirectional thyristor V1 conducting, ensuing negative half-wave bidirectional thyristor V1 not conducting, zero passage detection module exports zero cross signal at this negative half-wave, zero cross signal is the positive pulse that corresponding AC power bears half-wave, as shown in the pulse 1 in Fig. 5, pulse 1 width is less than 10ms; Single chip control module sends a width at the falling edge of pulse 1 and is not less than 10ms, is no more than the trigger impulse of 20ms, and control the ensuing cycle conducting of bidirectional thyristor V1, the representative value of this trigger pulse width is 15ms.

When being engraved in during AC power bears half-wave during being and stopping triggering signal exporting at random as shown in Figure 6, send the waveform example 2 of Lamp with ceiling fan control signal.The Lamp with ceiling fan control signal voltage waveform that Fig. 6 (a) exports for single fire wire output end AC1, Fig. 6 (b) is zero cross signal voltage waveform, and Fig. 6 (c) is voltage waveform after Lamp with ceiling fan control signal sampling shaping.Pulse 31 in Fig. 6 is zero cross signal positive pulse, and its width is close to 10ms.Single chip control module sends a width at the falling edge of pulse 31 and is not less than 10ms, is no more than the trigger impulse of 20ms, and control the ensuing cycle conducting of bidirectional thyristor V1, the representative value of this trigger pulse width is 15ms; Simultaneously using the falling edge of pulse 31 as time zero, 20ms place is the phase shift zero crossing of the 1st half-wave in data waveform, 30ms place is the phase shift zero crossing of the 2nd half-wave in data waveform, 40ms place is the phase shift zero crossing of the 3rd half-wave in data waveform, 50ms place is the phase shift zero crossing of the 4th half-wave in data waveform, 60ms place is the phase shift zero crossing of the 5th half-wave in data waveform, and 70ms place is the phase shift zero crossing of the 6th half-wave in data waveform.
When single chip control module sends data waveform, in the phase-shifting trigger moment of each half-wave of 6 continuous half waveforms of phase-shifting trigger, send a narrow trigger impulse.
Fig. 7 is Lamp with ceiling fan control signal sending control method, and realized by the program in single chip control module, its method is:
Steps A, judge whether Lamp with ceiling fan Setting signal changes, Lamp with ceiling fan Setting signal does not change, and maintains and does not send Lamp with ceiling fan control signal state, return steps A; Lamp with ceiling fan Setting signal changes, and enters step B;
Step B, determines Lamp with ceiling fan control signal;
Step C, sends a Lamp with ceiling fan control signal; Return steps A.
When Lamp with ceiling fan wall control unit does not send Lamp with ceiling fan control signal, when all Lamp with ceiling fan are in normal operating conditions, the voltage waveform that single fire wire output end AC1 exports is continuous whole single-phase sine wave.
When determining Lamp with ceiling fan control signal, first judge it is that the Lamp with ceiling fan Setting signal of which Lamp with ceiling fan changes, determine the address code of its correspondence, then by new Lamp with ceiling fan Setting signal according to Lamp with ceiling fan combined running state table determination Lamp with ceiling fan combined running state, and then determine its control code.If there is the Lamp with ceiling fan Setting signal of Lamp with ceiling fan corresponding to multiple address code to change, then first process one of them, send a Lamp with ceiling fan control signal; Have and untreatedly complete can enter step B again in steps A, process successively and send Lamp with ceiling fan control signal.
When judging whether Lamp with ceiling fan Setting signal changes, as long as there is more than 1, comprises 1 Lamp with ceiling fan Setting signal and change, then think that Lamp with ceiling fan Setting signal changes.
