Abstract
The utility model relates to a two-wire sub-ultrasonic remote control switch, which belongs to the field of sub-ultrasonic remote control switch manufacture. Because a power supply circuit and loads adopt parallel arrangement, the complete machine of the present sub-ultrasonic remote control switch needs to be connected with three wires externally which are inconvenient for installation and use. The switch of the utility model, the power supply circuit, and the loads are connected in series with a power supply; the switch and the power supply circuit supply power to a sub-ultrasonic receiving circuit and a flip-flop circuit; the sub-ultrasonic receiving circuit and the flip-flop circuit control the operation of the switch and the power supply circuit. Therefore, the complete machine of two-wire sub-ultrasonic remote control switch needs to be connected with two wires externally which are connect in series with the loads. The two-wire sub-ultrasonic remote control switch is mainly suitable for the remote control of household appliances, for example, a light fixture.
Description
The utility model belongs to inferior ultra-sonic remote control switch and makes the field.
Present inferior ultra-sonic remote control switch all adopts the three-wire type structure.Load and switch access in parallel power supply with power supply circuits.Link to each other with the power supply circuits output after inferior ultrasonic wave receiving circuit and the flip-flop circuit parallel connection, power to inferior ultrasonic wave receiving circuit and flip-flop circuit by power supply circuits, after inferior ultrasonic wave receiving circuit received inferior ultra-sonic remote control signal, the upset of control flip-flop circuit was by flip-flop circuit control switch and loaded work piece (as shown in Figure 1).
Because power supply circuits need be relation in parallel by the independent power supply of power supply and with load.Therefore complete machine (comprising power supply circuits, inferior ultrasonic wave receiving circuit, flip-flop circuit, K switch) needs external three electric wires (being power line A, B, control line C) wiring complexity to be not easy to install.
The purpose of this utility model is the inferior ultra-sonic remote control switch of a kind of two-wire system of design, makes it the use of connecting with load of only external two electric wires, is convenient to installation.
The purpose of this utility model is to realize by following design:
Remote control switching circuit by control load work is formed, and inserts power supply after switch and power supply circuits 3 are connected with load 4, links to each other with the output of switch and power supply circuits 3 after inferior ultrasonic wave receiving circuit 1 flip-flop circuit 2 parallel connections of control switch and power supply circuits work again.
After having adopted design as above, because remote control switch complete machine (comprising inferior ultrasonic wave receiving circuit 1, flip-flop circuit 2, switch and power supply circuits 3) and load 4 be series relationship, so complete machine only needs external two electric wires, is convenient to installation.
Description of drawings is as follows:
Fig. 1 is the prior art constructions block diagram
Fig. 2 is a structured flowchart of the present utility model
Fig. 3 is the circuit diagram of the utility model embodiment
Below, in conjunction with the accompanying drawings structure of the present utility model is described in further detail
As seen from Figure 2, switch of the present utility model and power supply circuits 3 are cascaded with load 4 and power supply joins, the inferior ultrasonic wave receiving circuit 1 of control switch and power supply circuits 3 work, flip-flop circuit 2 is connected in parallel and receives on the output of switch and power supply circuits 3 again.When inferior ultrasonic wave receiving circuit 1 received inferior ultra-sonic remote control signal, 2 upsets of control flip-flop circuit were by flip-flop circuit control switch and power supply circuits work.When being closed condition, switch and power supply circuits 3 not conductings, load 4 is not worked, and electric current is mainly exported low-tension current to inferior ultrasonic wave receiving circuit 1 by switch and power supply circuits 3 rectification current limliting step-downs at output after load 4, flip-flop circuit 2 power supplies.When being operating state, switch and power supply circuits 3 conductings, load 4 work, but this moment switch and power supply circuits 3 be in incomplete conducting state, promptly there is a low-voltage AC in the input at switch and power supply circuits 3.Power supply is exported low-tension current to inferior ultrasonic wave receiving circuit 1 through load 4 current limiting switches and power supply circuits 3 rectifying and voltage-stabilizings at switch and power supply circuits output at this moment, flip-flop circuit 2 power supplies.As seen remote control switch complete machine (comprising switch and power supply circuits 3, inferior ultrasonic wave receiving circuit 1, flip-flop circuit 2) is a series relationship with load 4, so complete machine only needs external two electric wires to be convenient to install and use.
Switch among Fig. 2 and power supply circuits 3, inferior ultrasonic wave receiving circuit 1, flip-flop circuit 2 can be realized by the 3a among Fig. 3,1a, 2a, work as piezoelectric ceramic piece HT and receive inferior ultra-sonic remote control signal after T in Fig. 3
