The utility model adopts the isolation of photoelectric coupling tube and the indication of an LED, and comprises a coding controlling circuit, etc., and thus the utility model has the advantages of favorable anti-interference ability, and distinct and convenient operation.

Description

A kind of appliance switch

The utility model belongs to the device that a kind of control apparatus is opened and closed.

China Patent No. is that 86200101 utility model discloses a kind of electric switch, has realized by a plurality of switches of design a lamp being opened and shut off independently.Its weak point is to be difficult to be implemented in different local a plurality of electrical equipment are carried out open and shut off.

The purpose of this utility model provides a kind of electronic installation that can control a plurality of electrical equipment in a plurality of different places.

The purpose of this utility model reaches like this: it is provided with especially by a plurality of coding circuits and a plurality of decoding circuit forms control circuit, and this control circuit contains a plurality of outputs and links to each other with a plurality of electric-controlled switchs accordingly.Above-mentioned control circuit is to constitute like this, each coding circuit comprises an integrated encoder, one group of button and corresponding peripheral cell, the output of each coding circuit interconnects, its line becomes holding wire, each decoding circuit comprises an integrated decoder and corresponding peripheral cell, and its input links to each other with holding wire by photoelectrical coupler, that is: each decoder can both receive this signal after any one encoder output control command; A plurality of outputs that each decoding circuit contains constitute the output of control circuit, and these outputs link to each other with the input of each electric-controlled switch accordingly.From the above,, link by holding wire each other when a plurality of encoders are arranged on different places as required with decoder, can be by the instruction of input switch on the different coding device, the purpose that control setting connects at different local electricity.

The purpose of this utility model can also so further reach: encoding control circuit is set, and its input signal is by introducing between encoder and the decoder, and introduces restricting signal by encoder one output, and its output links to each other with button.At decoder output display circuit is set.

From the above, each coding circuit all can be imported the switch command of each electrical appliance, receive by each decoding circuit, the output of decoding circuit is exported corresponding signal, and control the electric-controlled switch of corresponding electrical equipment, as control, promptly when ground floor is gone upstairs, can open the illuminating street lamp in each building to each interlayer illuminating street lamp in the high building, can close each floor illuminating street lamp when arriving the purpose floor, very convenient in the use, in addition, owing to be provided with encoding control circuit, make when many people input switch instruction simultaneously, decoding circuit receives only the switching signal of input at first, has avoided coding chaotic, owing to be provided with display circuit, the on off state of electrical equipment is come into plain view, and, strengthened the convenience of using because the every pair of coding circuit and decoding circuit can install in a control board, and its display light source can play the floor light effect to button.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1, the utility model principle key diagram.

The schematic diagram of Fig. 2, the utility model embodiment control board.

The schematic diagram of Fig. 3, another embodiment control board of the utility model.

Referring to Fig. 1, the utility model is in this embodiment by three control board kz1, kz2, kz3, controlling L1, L2, four electrical appliances of L3, L4, each control board all can be imported the switching signal of electrical appliance, switching signal is by output Io output, and by holding wire L transmission mutually between each control board, the signal that the control board basis receives is at each corresponding output Io1, Io2, Io3, Io4 output switching signal, and control corresponding electric switch K action, thereby can be implemented in the purpose of the different appliance switches of different local controls arbitrarily.

Referring to Fig. 2, each control board comprises coding circuit 1, decoding electrical equipment 2, photocoupler 3, encoding control circuit 4, display circuit 5, wherein: coding circuit 1 is by integrated circuit (IC) 1, K switch on its input pin, capacitor C 2, C3, resistance R 11 are formed, and comprise R1 and the switch triode BG1 that output inserts; Triode BG1 is the output of coding circuit 1; Decoding electrical equipment 2 is made up of integrated decoder IC2, photocoupler IC3, resistance R 21, capacitor C 21, trigger D, resistance R 2, switch triode BG2.IC1 LC2190 in the present embodiment, IC2 finishes with the LC2200 integrated package, its operation principle is as follows: by button K input electrical appliance switching signal, at output I11 is the 1 pin output signal of LC2190, by resistance R 1, triode BG1 is to holding wire L, each control board is on 13 pin of LC2200 by the input I111 that photoelectricity coupling platform pipe IC3 and R21 introduce decoder IC2 with the signal on the holding wire, decoder IC2 is then at corresponding output output switching signal, by d type flip flop IC4 reception and by display circuit 5 is the luminous demonstration of light-emitting diode ED, this moment, corresponding switching tube BG2 opened, relay J is closed, and electrical appliance L1 closes or be logical.Can be received by photoelectrical coupler IC3 by each control board by the signal on this figure visible signal line L, the on off state of each electrical appliance can show on the light-emitting diode ED in each control board, thereby be implemented in different local each electrical appliances of control, and can judge the on off state of corresponding electrical appliance from the state of light-emitting diode ED on the control board.Draw signal to encoding control circuit 4 from the IC3 output in addition, in the present embodiment, encoding control circuit 4 is that 5 pin of LC2190 limit button K1 jointly by NOR gate IC5 and resistance R 4, diode D1, capacitor C 1 and from the LED end of IC1, promptly after IC3 receives signal, the output C of IC5 is a low level, at this moment it is invalid to press K1, but if when pressing K1 itself its LED output high level to make C be high level, it is effective then to press K1.Thereby avoided several people's chaotic situation during input switch instruction simultaneously on the different coding device.Because each control board is different local, holding wire length outside is bigger, and photocoupler IC3 has played buffer action, makes the utility model that stronger antijamming capability be arranged, because the amplification of BG1 has strengthened the ability to bring along of IC1, the utlity model has the advantage of working stability.When electric trigger switch then can be without R2 and BG2 with can dig silicon without relay the time.

Referring to Fig. 3, control board mainly is made of single-chip microcomputer P, control command is imported by button K2, its code signal reaches on the holding wire L through R1, BG1, receive among each single-chip microcomputer P of input by the photoelectrical coupler in each control board, by the output output corresponding signal of single-chip microcomputer, the electric switch of control display and electrical appliance.Hence one can see that, and coding circuit 1 and decoding circuit 2 comprise that peripheral discrete component can be formed in the integrated circuit.

Coding circuit 1, decoding circuit 2, photocoupler 3 from the above, encoding control circuits 4 etc. can be selected different integrated circuits and peripheral cell to constitute as required, or they are designed in the integrated circuit, thereby it is more stable to reach work, the advantage that cost is lower.Electric in addition trigger switch also has multiple choices, and the d type flip flop that output connects of IC2 can have different selections according to the difference of IC2, as also can with JK flip-flop etc.
