Description

Digital multi-address controller for electrical switch

The utility model relates to a kind of switching device, particularly a kind of digital multiple-access control device of multipath electric switch.

In the prior art, when multi-use electrical is controlled respectively by one group of switch of concentrating, to its corresponding electrical appliance of controlling, the electric wire (direct current or exchange single-phase situation is analogized when heterogeneous, and is same down) of a special use need be arranged from each switch.Therefore, if will control N electrical appliance respectively, then need in the circuit with N+1 bar electric wire, wherein one is the shared ground wire of each electrical appliance.When N was big more, the construction of circuit wiring was got over complicated, and the time-consuming expense material of taking a lot of work is also got over serious.All the more so when connecting control more.

Task of the present utility model is to reform prior art, and making only needs to use two power lines, perhaps adds a control line at most, can carry out each other control to N electrical appliance in control place, thereby make the line construction of prior art simplify greatly.

Referring to Fig. 1, Fig. 2 and Fig. 3, the digital multiple-access control device of multichannel of the present utility model (being made as the N road) electric switch be by controller 1, and the switch 2(of N band address is called band location switch) and a control line 7 form.Be provided with encoder 8 in the controller 1, set the number that the button of holding 9 is controlled its outputs by N address code that is connected to it.The output of encoder 8 is received the input of buffer 10.Buffer 10-that is controller 1-output terminals A is connected to the B end of controlled each band location switch 2 by a control line 7.In each band location switch 2, the B end is connected to the signal input part of decoder 11.11 output C is connected to the trigger end (input end of clock) of bistable trigger IC12.The output D of bistable trigger 12 receives the control utmost point of bidirectional triode thyristor 14 through buffer 13.After two other utmost point of bidirectional triode thyristor 14 (negative electrode and anode) and electrical appliance 3 series connection, receive power supply 4 by power line 5 and 6.

By above-mentioned circuit structure as seen, each band location switch 2 receives the control signal that is produced by controller 1 by a shared control line 7.As its address information, when just thinking that it is identical with the inherent address sign indicating number of decoder in certain controlled switch, this switch just can move control signal with different numbers, and other has the switch of different address codes then unaffected.Therefore, controller can pass through a shared propagation ducts, and N switch carried out each other control.Further explanation to its operation principle will provide in conjunction with the embodiments hereinafter.Control signal contains more than one in season, during the address information (number) of as many as N, can do control simultaneously to a plurality of corresponding bands location switch again.

The control signal of foregoing circuit and the address of controlled switch, expressed by different number (address code).In fact, except that number, the address is the voltage available value also, and frequency is perhaps expressed by their part or all of combinations.The propagation ducts of above-mentioned control signal can be the electric wire of a special use, can be power line itself (with the control signal superposition at the power supply above-the-line promotion), also can be sound wave, ultrasonic wave, electromagnetic wave, infrared ray, light wave etc. can be so as to propagating the media of control signal.

The utility model compared with prior art has following advantage:

A. slave controller is to N switch and electrical appliance, only needs a shared control signal propagation ducts, needs the N bar to give the electric wire of each electrical appliance special use but not resemble as the prior art, thereby makes the structure of circuit simplify greatly, and overall economic benefit is very remarkable.

B. only need add one or more identical controller, need not to change original as long as the simple structure of a control signal propagation ducts and two power lines, can do multiple spot (connecting) control to multi-use electrical, if use prior art, the complexity of its circuit structure will be more more.

C. in the time of will doing the circuit expansion, the band location controlled switch and the electrical appliance that only need to increase newly are connected on the power line, and the control signal that controller can be issued additional contain appropriate address (can reequip or in controller, reserve this ability easily), and need not to install special-purpose electric wire from power supply additional to newly-increased electrical appliance.

D. use sound, ultrasonic, light, electromagnetic wave, when infrared rays etc. were propagated control signal, it is interior Anywhere that one or more controllers can be placed on certain limit, uses very convenient.

In three accompanying drawings of this specification, Fig. 1 is an overall electrical circuit diagram of the present utility model, and it is expressed from power supply 4, via controller 1, and power line 5 and 6 and control line 7 is to the annexation of controlled switch 2 and electrical appliance 3.Fig. 2 is the circuit of controller 1.Fig. 3 is the internal circuit of controlled switch 2.

In conjunction with Fig. 1, Fig. 2 and Fig. 3 provide an embodiment, with different digital as address control 20 (N=20) small cup electric light.In the circuit structure of controller shown in Figure 21, integrated circuit 8 is ternary encoders.A0-A11 is its ternary coding side, respectively can ground connection, and unsettled, or connect the button 9 that Vdd.A0-A11 is connected with N key.Press different keys, can obtain the number of the various combination of A0-A11, and with it from OUT of IC8 end and, through behind the buffer 10, the output terminals A serial of slave controller 1 output.Figure 3 shows that one of controlled switch of 20 tunnel (referring to Fig. 1 2) circuit.Behind control line 7, be input to decoder IC11 from the serial digital control signal of Fig. 2 controller output end A, carry out four comparisons continuously with the local address sign indicating number of this IC by A0-A11 determined from B end (Fig. 3, and referring to Fig. 1).During the state consistency of the A0-A11 of and if only if two integrated circuits of Code And Decode (8 and 11), positive pulse of C end output of decoder IC11.The level upset that this positive pulse is ordered the output D of the bistable trigger of being made up of CD4013 12.If the action of the odd of button 9 makes the D level point of CD4013 be uprised by low, then the action of even will make this level by high step-down.By the driver of being made up of triode and diode 13, this makes that bidirectional triode thyristor 14 1 logical is disconnected, thereby reaches the purpose that control is connected to these road electric light 3 break-makes of power supply 4.

Above we are that example has been done discussion with optional a certain road controlled switch.In its tangible above-mentioned whole process, digital controlled signal also has been added on other controlled switch by same propagation ducts (Fig. 1 7).But because the local address sign indicating number of the setting of decoder 11 and above-mentioned control signal digital different in these controlled switchs, the output perseverance that its C is ordered is a low level, and saltus step does not take place, so the break-make situation of corresponding electric light does not change.This shows, see Fig. 2 by operating different button 9(), the number of change control signal can be realized the control out of the ordinary to corresponding controlled switch.
