Due to the unfavorable factor of single live wire power getting, some producers develop zero live wire power getting intelligent control module, and Fig. 2 is the control principle of zero live wire power getting one way switch wireless intelligent control module.The input of control loop has (10) zero live wire power getting wireless intelligent control modules, (11) wall surface switch box, (12) intelligent object 220V live wire, the input of (13) 220V zero line, (14) intelligent object 220V control the composition such as live wire output, (15) switching signal control line, (16) one road mechanical switchs, (17) lighting load.Zero live wire power getting wireless intelligent module (10) is imbedded wall surface switch box (11), and intelligent object 220V live wire input (12) connects 220V live wire, and the input of (13) 220V zero line connects 220V zero line; Intelligent control module 220V controls live wire and exports (14) connection lighting load (17), and (15) switching signal control line connects an original road mechanical switch (16).Inside modules installs wireless transmitter, can carry out remote control by intelligent control host, and wall surface switch also realizes switch control rule by switching signal control pair intelligent object simultaneously.
Owing to needing the wiring of zero line in switch enclosure, under causing having completed at present the state not having zero line in finishing and switch enclosure, the application of zero live wire power getting scheme is limited to, need to imbed wireless intelligent control module in narrow and small switch enclosure simultaneously, all existing defects in functions of modules and heat radiation etc., so market has occurred the control mode of being connected with wireless intelligent control module by common wall surface switch, Fig. 3 has been the control principle drawing that regular tap is connected with wireless intelligent control module.Controlled live wire etc. formed by (21) regular tap, (22) wireless intelligent control module, the input of (23) 220V live wire, the input of (24) 220V zero line, (25) lighting load, (26).When regular tap closes, control live wire (26) and obtain electric, produce a power-on reset signal simultaneously, lighting load is connected when wireless intelligent control module obtains electric, when regular tap disconnects, then cut off the power supply in all loops, lighting load disconnects; When regular tap closes, wireless intelligent control module obtains electric, can accept controlled in wireless.The method remains common wall surface switch and obtains all functions, but when regular tap disconnects, wireless intelligent control module dead electricity, now wireless intelligent control module is by function out of hand.The program also exists when after power-off in addition, and the problem that when restoring electricity, load will all be opened, causes potential safety hazard.
Fig. 4 is Method And Principle figure of the present invention, constitutes single live wire control switch scheme by (31) single-pole double throw diverter switch, (32) power supply and accumulate loop, (33) single live wire control module, (34) wireless intelligent control module, (35) electronic switch, (36) lighting load etc.Power supply and accumulate loop (32) are connected to the incoming end of lighting load, single-pole double throw diverter switch (31) keeps normal closure state, and its power supply is realized by the live wire being connected to zero line in lighting load (36) and single-pole double throw diverter switch (31) UNICOM.When operation sheet dpdt double-pole double-throw (DPDT) diverter switch (31) switches, hot voltage can disconnect instantaneously in a shorter time slot, single live wire control module (33) pickup exports electronic switch (35) to after the signal that this live wire disconnects instantaneously processes, and realizes the control to lighting load (36) by electronic switch.Namely original mechanical switch action is converted to electronic switch signal and controls the opening and closing of electronic switch.If install wireless intelligent control module (34) at lighting load end, module can pass through power supply and accumulate loop (32) normal power supply, the control signal of wireless intelligent control module (34) is exported to electronic switch (35) simultaneously, single live wire Based Intelligent Control can be realized.Namely single-pole double throw diverter switch can retain the function of former wall surface switch, and newly-increased wireless intelligent control module can realize Based Intelligent Control again.
Fig. 5 is the schematic diagram of single live wire control module.Its current supply circuit is in parallel with wireless intelligent control module, is made up of (40) single-pole double throw diverter switch, (41) electric power loop, (42) power storage, (43) single live wire control module, (44) picking up signal, (45) signal shaping loop, (46) initial reset, (47) remember trigger, (48) output drives etc.Single live wire control module (43) contains picking up signal (44), signal shaping loop (45), initial reset (46) and memory trigger (47) and export driving (48).The power supply that electric power loop (41) and power storage (42) provide single live wire control module (43) normally to work, should be and be only confined to signal transacting and intelligent control module for electric loading, do not relate to the power supply of control load, so the power storage (42) maintaining power supply when disconnecting instantaneously is very easy to realize.
When pressing single-pole double throw diverter switch (40), diverter switch will switch to the other end from one end, and handoff procedure will cause 220V power supply micro breaks, but after finishing switching, 220V power supply can recover normal power supply again.Power storage (42) part guarantees that the wireless intelligent control module that single live wire control module (43) is connected with needs in instant cut-off process can normally work.The instant cut-off signal of picking up signal (44) part pickup power supply, after the shaping and stabilization process of signal shaping loop (45), deliver to memory trigger (47) make it reverse and keep, interval signal all can make trigger reverse once each time, and memory trigger (47) drives (48) to export electronic switch to by exporting.Signal shaping part is to prevent mechanical switch from causing the instability of switching signal in the shake that the process of action produces, can be automatically reset when powering up for the first time by setting initial reset (46), the problem all opened of switch during to restore electricity after preventing from having a power failure.
Fig. 6 is the control waveform figure of control method of the present invention.Waveform takes from gauge point A, B, C, D, E of Fig. 4 and Fig. 5.The waveform of two processes turned on and off for using diverter switch and the load of intelligent radio module controls respectively, (51) for pressing waveform during diverter switch connection load, (52) be waveform when wireless intelligent module control load turns off, (53) be waveform when wireless intelligent module control load is connected, waveform when load turns off when (54) are for pressing diverter switch.A is the 220V AC power waveform of single live wire control module picking up signal end input, can produce the micro breaks of 220V AC power waveform when diverter switch switches.B is the micro breaks signal by exporting after single live wire control module.C is the output waveform of wireless intelligent module, when wireless intelligent control module will output control pulse signal when receiving switch command.D is that memory trigger carries out reversing and exports the switching signal waveform of electronic switch after keeping to after receiving the trigger impulse of B or C.E is the waveform that actual loading controls on live wire.Can see, by to the monitoring of alternating current micro breaks signal and the control of electronic switch, can be implemented in gap that AC power disconnects instantaneously to complete and the break-make of load is controlled, can avoid diverter switch completely in handoff procedure because alternating current disconnects the impact to load caused instantaneously like this, ensure that the useful life of lighting load.And disconnecting the intelligent control module and single live wire control module that impact instantaneously concerning being subject to alternating current, we can overcome by the design of more protection power circuit the impact impacted and cause, and guarantee its reliability used.
The feature of the method utilizes switching over gap to cause power supply to be interrupted, by live wire, switching interruption is passed to the signal processing apparatus being connected to tail end of switch, correctly open gap is detected by circuit, using micro breaks signal as switch controlling signal, make lighting load complete break-make in interruption gap and control; Ensure the power supply of each module during instant cut-off, to guarantee that module stabilizes work simultaneously.Method this breach single live wire intelligent control scheme on complete function must the limitation of power taking in wall switch box, intelligent control module will move to the lighting load end of zero line, solve the powerup issue of module at all, remain again the controlling functions of original switch completely, be a kind of single live wire intelligent control method completely functionally simultaneously.
The method is combined with existing wireless intelligent module, and for fitting up the intellectualized reconstruction in room, switch enclosure also can realize reliable global function intelligent wireless without the need to zero line and control.
Signal processing apparatus can pick up the switching signal of switch, and control load become not have the control signal of false triggering by irregular instant cut-off signal transacting after.
Need the loop maintaining power supply to be confined to low power signal transacting and driving during instant cut-off, do not relate to control load, so be very easy to realize.
Diverter switch directly can use various brand double control switch commercially available at present and need not again develop, and remains the hobby of client completely; Also can be customized as requested by manufacturer, selectable range is broad.
Because module can move on to the incoming end of lighting apparatus above, can not consider to should be at present the restriction will imbedding the module volume brought in switch enclosure, the design for controllable lighting power and wireless receiving and dispatching antenna more can have surplus.
Be connected with existing wireless intelligent module after using single live wire control module of this control method can configure power supply and accumulate loop, the object with control load while of wireless intelligent module is reached by the switching signal control line controlling wireless intelligent control module, can mate with various intelligent object, applicability is broad.
Use single live wire control module of this control method also can be integrated into intelligent object inside, become and both controlled by wall surface switch, also by the one-piece type equipment that wireless intelligent module controls, reduce the wiring of installation process, improve installation effectiveness.
This control method also can be integrated in various lighting load with wireless intelligent control module simultaneously, becomes Based Intelligent Control load.
After using this control method, only need to be associated in live wire loop by increase double control switch and by switch series in live wire loop, multipoint wireless Based Intelligent Control can be realized by a live wire.
This control mode more can be used alone on the multiparty control to same load, and need not be connected with intelligent object.Use the present invention by realizing multiparty control after the common double control switch of live wire serial connection, the wiring requirements of complexity and the switch of special construction when realizing multiparty control at present can be avoided completely.
