More specifically, see Fig. 9, flash signal detecting unit 101 in the embodiment of the present invention comprises rectifier bridge D1, optocoupler U1, resistance (R1-R5), electric capacity C1 and electrochemical capacitor C2, series capacitance C1 between first ac input end of rectifier bridge D1 and live wire, resistance R1 is in parallel with electric capacity C1, resistance in series R5 between second ac input end of rectifier bridge D1 and zero line, first DC output end of rectifier bridge D1 and electrochemical capacitor C2 positive pole, resistance R2 first end is connected with resistance R3 first end, resistance R2 second end is connected with optocoupler U1 front end positive pole, second DC output end of rectifier bridge D1 and electrochemical capacitor C2 negative pole, resistance R3 second end is connected with optocoupler U1 front end negative pole, optocoupler U1 rear end negative pole is connected with resistance R4 first end and control module 104, resistance R4 second end ground connection, optocoupler U1 rear end positive pole is connected with power conversion unit 105.Wherein, civil power by rectifier bridge D1, enters optocoupler U1 by resistance R2, R3 dividing potential drop after electric capacity C1, resistance R1 resistance-capacitance depressurization after electric capacity C2 filtering.When civil power has electricity, optocoupler U1 conducting, optocoupler U1 output terminal (as figure FLASH place) perseverance is high level; When civil power flash, optocoupler U1 ends, and output terminal can export the low level pulse signal of a proportional corresponding pulsewidth according to the time of flash.Resistance R5 shields, in order to eliminate the spike of energising moment.
Wherein, normally closed touch switch in the embodiment of the present invention is can realize flash disconnection duration to be less than the normally closed switch that energy-storage travelling wave tube is the control module 104 normal power supply time, as the normally closed switch that flash disconnection duration is less than 3 seconds, comprise doorbell switch, the single-pole double-throw switch (SPDT) of two output terminal short circuits or other be closed touch switch etc. under normal circumstances, specifically can be reequiped by existing single-pole double-throw switch (SPDT), or directly customize from manufacturer.Under normal circumstances, when staff clicks once aforementioned normally closed touch switch, about about the 200ms of flash time, sustainable power supply 1-3 second after the power-off of control module 104(common power conversion unit 105 can not be affected) work.
Below in conjunction with Fig. 6 and Fig. 7 to being described based on the course of work that is manual and radio double-control system in the embodiment of the present invention: switch performance element 103 is made up of relay, and control module 104 is single-chip microcomputer.When there is flash, if the result that flash causes is to close electrical appliance, when flash is recovered, whole system has electricity, and single-chip microcomputer also can make relay disconnection electrical appliance power.Suppose that flash is sustained, because overall not power supply, electrical appliance does not have electricity naturally yet.If the result that flash causes is to open electrical appliance, so at the end of flash, whole module is all under having electricity condition, and single-chip microcomputer also can allow relay open electrical appliance.General power conversion unit, because there is electric capacity inside, in the power-off state, can support single-chip microcomputer work 1-3 second, then, during flash (about about the 200ms of flash time), when the flash of shutdown signal being detected, just allow relay disconnecting circuit.If the flash of start signal detected, then at the end of flash, just allow relay connection circuit.Particularly, suppose 0: 0: 20 Beijing time, when having carried out a flash, suppose that this flash time is 1s, following situation will be occurred:
(1) if current power device is in running order, so this flash needs wireless processing module to perform the action of closing electrical appliance, processing mode: during 20.1 seconds time, single-chip microcomputer has found this flash, and detect and to be currently out, so make relay disconnecting circuit.Relay is power-off to 20.1-21 during this period of time second, and no matter it is Chang Kai or normally closed relay, and electrical appliance does not all have electricity.During 21 seconds time, flash terminates, and power supply is normal, and single-chip microcomputer guard relay disconnects then closes electrical appliance.
(2) if current power device is in off-position, so this flash needs wireless processing module to perform the action of opening electrical appliance, processing mode: during 20.1 seconds time, single-chip microcomputer has found this flash, and detect that current is close, action is not carried out to relay, during time 20.1-21 second, relay is power-off, so electrical appliance does not have electricity; During 21 seconds time, flash terminates, and power supply is normal, and Single-chip Controlling relay closes then opens electrical appliance.
Said process is that a supposed situation illustrates, does not act on restriction of the present invention.But known by above-mentioned supposed situation: single-chip microcomputer performs and closes action, is occur in that time flash being detected.And work is started in single-chip microcomputer execution, be occur in flash to terminate, power normal that time.During whole flash, wireless communication unit and switch performance element can not work, but single-chip microcomputer must maintain electricity (being satisfiable under normal circumstances).

See Figure 11, in another embodiment that the embodiment of the present invention provides, in the actual environment itself having had double control switch control, use the present invention equally can realize wireless multi-control.As shown in figure 11, by two output terminal short circuits of any one double control switch in electrical appliance circuit, now any one double control switch all will become touch switch, can cause power supply flash during click.
This invents maximum advantage is do not need to transform former circuit, only needs to replace former switch, and install wireless processing module additional around electrical appliance, under being highly suitable for domestic environment, carry out intelligent regeneration to traditional electrical equipment.Owing to regular tap to be replaced to improved double control switch or other touch switch, all without the need to additional space, so replacement process is also very simple.
