AC power interface 206 comprises label 244 and is positioned at the below of respective threaded rod and four sockets 246-1,246-2,246-3,246-4 being marked by label 244.Socket 246-1,246-2,246-3,246-4 are used for stube cable/electric wire.The adjustment of screw rod can cause cable to be connected with electric equipment 200 or to connect disconnecting.In the embodiment shown in figure 2, AC power is carried by the neutral line 220 and live wire 218.In one embodiment, the neutral line 220 is connected to socket 246-3, and live wire 218 is connected to socket 246-2.Load device 210 is connected to socket 246-1,246-4.Load device 210 is connected to socket 246-1 by live wire 258.Socket 246-3,246-4 of being labeled as " N " and " load N " are connected with each other.Therefore, load device 210 is connected to socket 246-4 by the neutral line 260.Electric equipment 200, live wire 258, load device 200 and the neutral line 260 can form closed circuit.Therefore, electric equipment 200 may be controlled to the power supply that load device 210 is powered.
Out-put supply interface 208 be connector 106 shown in Fig. 2,112 specific implementation, comprise label 254 and be positioned at the below of respective threaded rod and three sockets 256-1,256-2,256-3 being marked by label 254.Socket 256-1,256-2,256-3 are used for stube cable/electric wire.The adjustment of screw rod can cause the connection of cable and electric equipment 200 or be connected disconnection.Ac supply signal or DC power signal can output to three-way switch 214-1 by socket 256-2, the 256-3 marked by switch symbols.In one embodiment, output signal can be the ac supply signal being sent to three-way switch 214-1 by live wire 230.Electric equipment 200, live wire 230, multipath switching system 215 and live wire 218 can form closed circuit.Therefore, the switching of two three-way switches 214-1,214-2 and DPST can affect the operation of electric equipment 200, and triggers the response from electric equipment 200.
The AC-DC converter 212 of electric equipment 200 is for being converted to the low dc voltage of other assembly for electric equipment 200 by the ac input signal carried by the neutral line 220 and live wire 218.In the embodiment shown in figure 2, AC-DC converter 212 uses needs the neutral three line designs connected.In some embodiments, AC-DC converter 212 uses two lines without neutral link to connect.AC-DC converter can use the normal voltage in country variant and area to carry out work, comprises North America, Europe, the Middle East, Central America and Caribbean area, South America, Africa, Australia and Oceania.In one embodiment, the input ac voltage of 110V/60Hz or 230V or 240V/50Hz can be converted to suitable low dc voltage by AC-DC converter.Such as, the AC power input voltage of about 120V can be converted to the internal dc voltage of the value of 5V or any appropriate by AC-DC converter.
The switch module 222 of electric equipment 200 for control load device 210, such as, for adjusting weak load device 210 (as reduced the power supply being supplied to load device 210) or opening/closing load device 210.The tune of load is weak is not limited to the luminous intensity reducing or increase electric light.In one embodiment, switch module 222 can make the rotating speed of electric fan rise or decline.Switch module can adjust weak or opening/closing load device 210 under the control of MCU module 216.Switch module 222 can comprise relay switch, exchange silicon keyholed back plate (TRIAC) circuit or other suitable switch module known in the art arbitrarily.
The MCU module 216 of electric equipment 200 is for controlling other assembly (such as, switch module 222, AC power interface 206 and/or out-put supply interface 208) of electric equipment 200.MCU module can control switch module, AC power interface 206 and/or out-put supply interface 208, to respond the d. c. voltage signal from AC-DC converter 212.MCU module can be implemented as microcontroller form, and can be powered by AC-DC converter 212.
In one embodiment, ac supply signal is outputted to three-way switch 214-1 by socket 256-2 or 256-3 and live wire 230 by MCU module 216.The voltage exchanging out-put supply signal can be identical or close with the voltage of the alternating current input power supplying signal being input to electric equipment 200 by live wire 218.In certain embodiments, AC power input signal voltage and be about 120V (such as within 120V ± 10%) or about 230V (such as within 230V ± 10%) from the voltage of the output signal of socket 256-2 or 256-3.Although provide the example voltages of alternating current output signal, the voltage of alternating current output signal can be the value of any appropriate, is not limited to the value of provided example voltages.
When in two three-way switch 214-1,214-2 and DPST 217 is switched, the movable switch contact (throwing end) of this diverter switch moves to the second fixed contact (node) from the first fixed contact (node side).At switching instant, what the node side of this diverter switch did not connect this diverter switch throws end arbitrarily, therefore produces high voltage at out-put supply interface 208 place.After switching instant, what the node side of this diverter switch was connected to this diverter switch throws end, therefore gets back to normal low level at the voltage at out-put supply interface 208 place.In certain embodiments, MCU module 216 detects the change in voltage at out-put supply interface 208 place, and correspondingly diverter switch module 222.Fig. 3 is the exemplary waveforms of voltage about switching over event at out-put supply interface 208 place.By in diverter switch 214-1,214-2,217, the waveform between time point " T0 " and " T2 " will be caused.The mechanical shaking of active service switch (active switch) will cause twice rising edge and twice trailing edge.At switching instant, what the node side of active service switch did not connect this active service switch throws end arbitrarily.Therefore, out-put supply interface 208 place will produce high level voltage, and waveform rises to high voltage " VH " from low-voltage " VL ".Due to the mechanical shaking of active service switch, voltage waveform is made to drop into low-voltage " VL " within time point T1 place's short time.Immediately after time point T1, waveform gets back to high voltage " VH ".After switching instant, what the node side of active service switch was connected to active service switch throws end, and therefore, waveform is reduced to low-voltage " VL " at time point T2 place from high voltage " VH ".MCU module 216 detects the unexpected rising (such as rising edge) of voltage waveform and declines (such as trailing edge) suddenly, switch module 222 is switched on/off, and AC power is supplied to load device 210 by start/stop.
MCU module 216 can use software program to the notice of the monitoring and switch module 222 that realize waveform.Software program can be stored in by the addressable memory module of MCU module.The example of the software program that can be used in MCU module 216 will be provided below.But the realization of operable software program is not limited to provided example in MCU module 216.
void ButtonInterrupt()interrupt INUM_INT0
