The utility model content

Problem to be solved in the utility model is how to provide a kind of multichannel to touch delay controller, this multichannel touches delay controller and adopts the many places touch manner to control a lamp simultaneously, not influenced by environment sound size, illumination power, installation wiring is convenient, can realize all street lightings of may command of many places touch sensible sheet, lamp is opened bright back and is extinguished automatically after several minutes, plays the walking along the street of turning on light night, the effect of saving electric energy again simultaneously.

The technical problem that the utility model proposed is to solve like this: construct a kind of multichannel and touch delay controller, it is characterized in that: comprise power-supply circuit, monostable circuit and illuminating lamp control circuit; Power-supply circuit is made up of transformer, bridge rectifier and filtering capacitor, transformer (T) is elementary to be connected with terminal (B) with the terminal (A) of external connection respectively, terminal (A) connects on the lighting circuit live wire (L), and terminal (B) connects on the lighting circuit zero line (N); Monostable circuit is by integrated circuit block, resistor (R1), capacitor (C4), capacitor (C2), capacitor (C3), touch sheet (P1), touch sheet (P2), touching sheet (P3) forms, touch sheet (P1), touch sheet (P2), touch sheet (P3) links to each other and is connected with capacitor (C4) end together, capacitor (C4) other end connects integrated circuit block pin (2) end, resistor (R1) is connected+9V feeder ear and integrated circuit block pin (7) end, capacitor (C2) anodal termination integrated circuit block pin (6) end, the public ground of its negative pole end connection circuit, integrated circuit block pin (4) end links to each other with pin (8) end and is connected together+the 9V feeder ear, its pin (1) termination circuit common, its pin (3) end connects the negative pole of protection diode (D5), and capacitor (C3) is connected between integrated circuit block pin (5) end and the public ground of circuit; The illuminating lamp control circuit is made up of relay (J) and protection diode (D5); contact (K) end of relay (J) is connected with external connection terminal (A), its other end is connected with external connection terminal (C); external connection terminal (C) is connected with illuminating lamp (L) end, and illuminating lamp (L) other end is connected on the zero terminal (B).

The beneficial effects of the utility model are: this multichannel touch delay controller adopt many places touch sensible sheet mode all lamp of may command open, lamp is opened after bright several minutes and is extinguished automatically, plays the effect of not only throwing light on but also saving electric energy; This product safety is reliable, stable performance, not influenced by environment sound size, illumination power, and installation wiring is all very convenient.

Description of drawings

Accompanying drawing 1 is a circuit structure diagram of the present utility model.

Embodiment

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

As shown in Figure 1, in the frame of broken lines the utility model circuit structure annexation figure, A, B, C, D is four external external connection terminals of product, the elementary end of external connection terminal A and transformer T, relay contact K one end is connected, be connected on outward on the lighting circuit live wire L, the external connection terminal B and the primary other end, illuminating lamp one end is connected, be connected on outward on the lighting circuit zero line N, external connection terminal C is connected with the relay contact K other end, the other end of external illuminating lamp, external connection terminal D is connected with capacitor C4, can pass through the external touch sheet metal of lead P (P1 respectively, P2, P3 ...) be subjected to the human-induced signal act on control street lamp open.

The utility model multichannel touches delay controller after connecting on the circuit, the direct voltage of alternating current 220V voltage output+9V after 5W transformer T transformation, rectifier D1-D4 rectification, capacitor C1 filtering uses for the monostable circuit and the relay work of compositions such as LM555.Usual sheet P (P1, P2, the P3 of touching ...) hold non-inductive voltage, capacitor C2 end is held inside discharge off over the ground by the pin (7) of LM555, pin (3) end output low level, and the coil no current of relay passes through, its contact K is in open-circuit condition, and street lamp L does not work; When needs are turned on light, touch any induction metal plate P (P1, P2, P3 are installed in the different location) with hand, human body sensing noise signal voltage is added to trigger end pin (2) end of LM555 by capacitor C4, make output pin (3) end transfer high level to by low level, relay gets electrical contact K closure, and street lamp L lights; End the pin (7) of LM555 end inside simultaneously, power supply is just given capacitor C2 charging by resistor R 1, be that street lamp is lighted and regularly begun, when powering on, capacitor C2 presses when being raised to supply power voltage 2/3, the inner conducting of integrated circuit block LM555 (7) pin, capacitor C2 discharges over the ground by (7) pin inside, makes output (3) pin transfer low level to by high level, relay electric-loss contact K open circuit, street lamp L extinguishes.Timing is by resistor R 1 and capacitor C2 decision, and this multichannel touches delay controller and is designed to 2 minutes, increases resistor R 1 resistance, can prolong the street lamp opening time.
