CN2221282Y - 2-line multiple timer - Google Patents

Abstract

The utility model relates to a 2-line multiple timer changing the traditional three lines (triggering and output) into 2 lines, having simply installation and economic practicality to control multi-floor stairs lamps. A 2-line function is converted by a timing control relay, when a button is triggered, the 2-line function is converted to 'output ' from 'trigger ' and simultaneously starts to time, an illuminating lamp is turned on, and when the timing time is over, the illuminating lamp is turned off, and a circuit is also restored to a 2-line triggering state. The circuit only changes the original output alternate current 220 volts to pulsed direct current 220 volts, and the common button is provided with a diode, and then the utility model can achieve the purpose that the three lines are combined into the two lines.

Description

The multi-joint timer in two wires

The utility model be a kind of can practical timer in multi-storey residential buildings or the control of office building stair light, it was not only easy by dress, but also economical and practical.

At present, known stair light control circuit is the series connection control load, traditional electric wiring, the control of bigeminy switch, three-way switch control or three above control circuits, three above control circuits in actual the use, cumbersome because of circuit in fact departed from actual use value.Moreover it can not reach energy-conservation timing controlled.There is single lamp timer control can not satisfy user's convenience again in addition.If use existing three-way timing controlled, will bring by the dress complexity, uneconomical again, so do not obtain promoting yet.

The purpose of this utility model provides the multi-joint timer in two wires of a kind of easier by dress, economical and practical again control multilayer stair light, and it is furnished with the button of the corresponding transformation of the way, if be extended to huge numbers of families, will bring for social each side and greatly facilitates and safety.

The purpose of this utility model is achieved in that in common timer construction, utilizes former relay control to exchange output and changes into pulsating direct current output-220V, also can make illuminating lamp work equally.Relay (1 * 1 contact structure) moving contact is pulsating direct current or control line+6V output, relay is when release condition like this, the output of control line+6V by timer external loop (promptly connecing the button loop) but incoming timing device trigger impulse control timer work, the relay adhesive, moving contact output ripple direct voltage is lighted illuminating lamp and beginning timing, at this moment if mistake touches the button, because the effect of diode in the button, will can short circuit.When being timed to setting-up time.Relay discharges, and moving contact output returns to normal again+the 6V state.

Owing to adopt such scheme, can change traditional three-way by dress for the two wires by dress illumination stair light, and in circuit, only increased in rectification circuit and the button only usefulness diode, to reach the purpose that former three-way control break becomes two line traffic controls, whole multilayer stair light illumination control circuit is oversimplified greatly, not only made things convenient for but also saved 1/3 lead of tradition by dress by dress, economical considerable.

The utility model is described in further detail below in conjunction with drawings and Examples

Figure one is circuit theory diagrams of the present utility model.

Figure two is that the circuit element printing forme is schemed by dress.

Figure three is button circuit figure

Figure four installs indicating circuit figure at night additional in the button.

In Fig. 1,1,2 ends are alternating current 220V inputs, and BX is total fuse, B is the control circuit power transformer, D1 and D8 are rectifier diodes, and C1, C3 are filter capacitors, and R1, R2 are resistance, D9 is a diode, C2 is a timing capacitor, and T is the FX555 integrated circuit, and J is a relay, L1 ... Ln is an illuminating lamp, TAN1 ... TANn is a band diode button.

Fig. 1 circuit theory: D1-D4 forms 220 volts of rectification circuits that rectification is direct current 220V of interchange.D5-D8, C1 have formed the power pack of control circuit, and R1, D9, TAN have formed the circuits for triggering that 2. T holds.Circuit R2, C2, T, C3, J have formed timing circuit.1,2 lines are that alternating current 220V is imported into end.A, b line are timer output (or triggering input) end.L1 ... Ln, TAN1 ... TANn is respectively the element in parallel on a, the b line.When normality, 2. T holds is to be higher than 2/3VCC, and 3. end output is low level, and J does not work.When pressing TAN, 2. VCC holds to the negative pulse triggering at T through R1D9, and C2 finishes by circuit instantaneous discharge in the T, timing circuit VCC through R2 to C2 begin charging 3. end work for high level output J, a, b line are output as 220 volts of direct currents, L1 ... Ln lights simultaneously.When charging to 2/3VCC on the C2,3. T holds and will recover low level, and J does not work, L1 ... Ln extinguishes, and entire circuit returns to normal again.This circuit is maximum regularly can to reach 180 seconds, so can satisfy instructions for use at common residential building.Timing calculates T=1.1R2C2.

Fig. 3 is the band diode button circuit of corresponding supporting two wires timer work, and this button can be gone here and there diode in conventional push button, and diode reverse is withstand voltage more than 500 volts.In addition, if will install night indication additional in button, also can install a resistance easily additional and a light-emitting diode gets final product, physical circuit is seen Fig. 4.

Claims (2)

1, a kind of timing controller, by being connected in series diode button trigger starting circuit, timing circuit, reaching output is the electrical connection circuit that direct current signal is formed, it is characterized in that: output signal line starts line with triggering and share the two wires, in timing circuit, the timing controlled relay is changed the electrical connection circuit of two wires function simultaneously.
