Abstract
The utility model relates to a two-wire typed remote control electricity saving switch, belonging to the field of electronic remote control switch manufacture. The present remote control switch adopts a single current limiting step-down voltage power supply circuit to supply power to a low-voltage circuit; the complete machine needs to be connected with at least three wires externally, which is inconvenient for installation and use. According to the static watching or operating state of loads, the utility model adopts two corresponding circuit connection modes, namely, a low-voltage circuit is connected in series with a resistor, rectification, and the loads, or the low-voltage circuit is connected in series with the rectification, the loads after connecting in parallel with a voltage-stabilizing switch. The complete machine needs to be connected with two electric wires externally which are connected in series the loads. The utility model is mainly used for the remote control for electric appliances, for example, a light fixture.
Description
The utility model belongs to Electronic Remote Switching and makes the field
At present, various remote control switches all adopt three-wire type, power supply after electric capacity, resistance, current limliting step-down to low-voltage circuit (receiving circuit 1, flip-flop circuit 2) power supply, after receiving remote signal, receiving circuit 1 makes flip-flop circuit 2 upsets, the break-make of control main switch K, work (as shown in Figure 1) owing to adopt single current limliting step-down power supply circuit by B point control load DZ, therefore complete machine needs external three electric wires, be power line A, C control line B, the wiring complexity, simultaneously static state is waited for and all be that same circuit is powered to low-voltage circuit 1,2 during operating state, so power consumption is bigger.
The purpose of this utility model is a kind of two-wire system remote control battery-conserving switch of design, makes it as regular tap, has only two external cord, and more economizes on electricity than existing remote control switch.
The purpose of this utility model is to realize by following design
By low-voltage circuit, power supply circuits are formed, low-voltage circuit (comprises receiving circuit 1, flip-flop circuit 2) by bifurcation supply power with double circuit circuit 4 and rectification D, load DZ series connection, low-voltage circuit 1,2 and the bifurcation resistance R that supplies power with double circuit in the circuit 4 was connected and is then connected with rectification D load DZ when static state was waited for, during operating state, stabilized switch 3 conductings, low-voltage circuit 1,2 is connected with rectification D load DZ after a line and stabilized switch 3 are in parallel.
After having adopted above-mentioned design, remote control switching circuit only external two electric wire A ', B '.Wiring is simple, adopt bifurcation to supply power with double circuit simultaneously, and the low-voltage circuit static working current is lower than operating state, can reduce static state to wait for power consumption, reaches purpose of saving.
Description of drawings is as follows:
Fig. 1 is the prior art constructions block diagram
Fig. 2 is the utility model structured flowchart
Fig. 3 is the circuit diagram of the utility model embodiment
Below in conjunction with accompanying drawing principle of the present utility model is described in further detail
As seen from Figure 2, power supply A, C is after load DZ and D rectification, supply power with double circuit circuit 4 to low-voltage circuit (receiving circuit 1 through bifurcation again, flip-flop circuit 2) power supply, when circuit is static stand-by state, stabilized switch is closed, low-voltage circuit with after resistance R is connected again with rectification D, the load series connection, power supply mainly through the step-down of resistance R current limliting to low-voltage circuit 1,2 power supplies, when operating state, stabilized switch 3 conductings, load DZ work, low-voltage circuit through a line and stabilized switch 3 in parallel again with rectification D, load DZ series connection, power supply is through load DZ, stabilized switch 3, the current limliting voltage stabilizing is powered to low-voltage circuit.Be exactly in fact static state when waiting for, the high-tension electricity that A ', B ' are 2 is powered to low-voltage circuit by the R pressure limiting after the D rectification, and the low tension of 2 of A ', B ' is directly powered to low-voltage circuit after the D rectification during operating state.The static state of complete machine is waited for or operating state is determined by control of remote controller by low-voltage circuit 1,2.
Supply power with double circuit circuit 4 and stabilized switch 3 of bifurcation can be realized by 4a, 3a among Fig. 3 among Fig. 2, in Fig. 3 by controllable silicon SCR 1, SCR2 voltage stabilizing didoe DW, stabilized switch 3a is formed in photoelectricity coupling 5, form the bifurcation circuit 4a that supplies power with double circuit by stabilized switch 3a and static current-limiting resistance R, A ', B ' point-to-point transmission alternating current are direct current through the D1-D4 full-bridge rectification.After receiving remote signal, receiving circuit 1 makes flip-flop circuit 2 upsets, flip-flop circuit 2 output low levels when waiting for for static state, and Rt is high impedance SCR1, not conductings of SCR2 in the photoelectricity coupling 5, is powered to low-voltage circuit 1,2 by the step-down of R current limliting.When being operating state, flip-flop circuit output high level, make the SCR1 conducting through photoelectricity coupling 5, trigger SCR2 conducting load DZ work by DW, simultaneously, because the DC-pulse after the effect full-bridge rectification of DW, when the not triggering and conducting just conducting of SCR2 when greater than the voltage stabilizing value of DW of SCR2 during less than the voltage stabilizing value of DW of its voltage, promptly the SCR2 two ends produce the DC-pulse that voltage amplitude is about the DW voltage of voltage regulation and power through SCR1, a alignment low-voltage circuit 1,2.Also can save SCR1 when the power consumption of low-voltage circuit operating state is low is certainly directly powered to low-voltage circuit 1,2 by photoelectricity coupling 5.
This two-wire system remote control battery-conserving switch can adopt different receiving circuits 1 to make different two-wire system remote control battery-conserving switches according to different remote control modes, as infrared, radio, ultrasonic wave, inferior ultrasonic wave etc.
