Fig. 1 is the structural block diagram of two-wire power supply control panel, as shown in Figure 1, it is by sensor, controller, wireless module And power supply composition.Sensor usually can be touch key-press, and trigger signal is transmitted to controller after sensor is triggered It is interior, corresponding control signal is further generated according to trigger signal by controller, and signal will be controlled by wireless module and sent To lamp, and then lamp is made to enter corresponding state, for example, control it is bright, go out or for lamp light modulation etc..However, this control panel needs Line voltage is converted into suitable voltage by power supply and powered to controller and other parts by two-wire (firewire and zero curve) power supply, control Panel processed is to be connected in parallel with lamp.
Fig. 2 is the wiring diagram of traditional metope switch, as shown in Fig. 2, traditional metope switch is series connection with lamp, and Only string needs rewiring if the control panel powered with two-wire to substitute if traditional metope switchs, limits on firewire The use of control panel.For the ease of substitution traditional metope switch, single live wire power getting technology is become more and more important.Fig. 3 is to pass The single-fire-wire electronic switch architecture diagram of system comprising AC-DC power supply, controller communication module, relay further include turning on light to take electricity Circuit and switching tube S1.In traditional single live wire power getting, it can realize that timing takes electricity or constant voltage to take by above-mentioned device Electricity, principle are that when the lamp is switched off, relay is to disconnect, and 220V voltage is converted into low pressure to controller and led to by AC-DC power supply Believe module for power supply.When turning on light, relay closes.Power-supply circuit of turning on light is opened and is turned off by control switch pipe S1, is Controller communication module is powered, and is that price often compares by the shortcomings that conducting and shutdown of control relay circuit , there are sound in valuableness, and volume is big, when switch, and switch is limited by the service life, can not carry out zero potential switch etc., and if it is more Way switch then needs to increase corresponding relay.
A kind of alternative solution is that the function of relay is realized with transistor.Fig. 4 is single channel transistor in the prior art The architecture diagram of the single-fire-wire electronic switch of switch.As shown in figure 4, it realizes identical function with a pair of transistor.But this side The shortcomings that case, can only exactly design one-way switch, if it is multichannel it will cause electric current crossfire, cannot achieve to variable connector Control.
To solve the above-mentioned problems, the present invention provides a kind of single-fire-wire electronic switch.Fig. 5 is a reality according to the present invention The circuit diagram of the single-fire-wire electronic switch of example is applied, as shown in figure 5, the single-fire-wire electronic switch includes first switch load circuit 1 Second switch load circuit 2 in parallel, controller communication module 3 with the first switch load circuit 1, wherein first opens Closing load circuit 1 includes first switch circuit 1a, the first load L1, first switch circuit 1a and the first load L1 series connection in city Electric both ends, second switch load circuit 2 is identical as the basic structure of first switch load circuit 1, including second switch circuit 2a, At alternating current both ends, the first of controller communication module is defeated for second load L2, second switch circuit 2a and the second load L2 series connection Outlet Dr1 is connect with first switch circuit 1a, second output terminal Dr2 is connect with second switch circuit 2a, is received for basis Turn on light and signal and turn off the light signal, pass through the first output end Dr1, second output terminal Dr2 output control signal and control first switch The conducting and shutdown of circuit 1a, second switch circuit 2a.
Fig. 5 merely illustrates the structure of double switch load circuit illustratively, further includes more than two-way in actual conditions The case where paralleling switch load circuit, when there is more switching load circuits, each switching load circuit is all made of and this implementation First switch load circuit 1, the identical circuit structure of second switch load circuit 2 in example, and each switching load circuit in parallel, this Invention does not enumerate herein.
Based on single-fire-wire electronic switch proposed by the present invention, the control to variable connector load circuit may be implemented, and Variable connector load circuit works independently, and is independent of each other, is not in electric current crossfire problem.
In practical work process, when controller communication module 3 receive first switch load circuit 1 turn on light signal when, Controller communication module exports high level, first switch circuit 1a conducting by the first output end Dr1, and the first load L1 works, When controller communication module receive first switch load circuit 1 turn off the light signal when, controller communication module 3 passes through first defeated Outlet Dr1 exports low level, first switch circuit 1a shutdown, the first load L1 rest;When controller communication module receives Two switching load circuits 2 turn on light signal when, controller communication module 3 by second output terminal Dr2 export high level, second opens Powered-down road 2a conducting, the second load L2 work, when controller communication module 3 receives the letter of turning off the light of second switch load circuit 2 Number when, controller communication module by second output terminal Dr2 export low level, second switch circuit 2a shutdown, second load L2 Rest.
