Description

Intelligent motor timing controller

Technical field:

The utility model relates to a kind of timing controller, particularly a kind of double circuit timing controller.

Background technology:

Now, timing controller is widely used in various household electrical appliance of control and lighting apparatus.For example, water dispenser, water heater, electric fan, electric blanket, radio-cassette player, aquarium etc., and the lighting apparatus in hall, aisle and room.Some are used for the mechanical timer of control load power supply getting up early, exist work noise big, and the control time is short, failure rate height, defective such as useful life is short.Evolution is to the electronic controller that generally uses at present gradually.The electronic controller function of use is promoted to possessing multiple function by early stage simple functions.The general controller that belongs to the single channel control output end, functions such as not fault detect voluntarily, automatic warning.

Summary of the invention:

At the defective and the deficiency of prior art, the purpose of this utility model is to provide a kind of double circuit timing controller, adopts the two-way control load in this circuit, and fault alarm function is provided.

The technical scheme that the utility model provides is:

Intelligent motor timing controller, the 220V alternating current is exported 5 volts, 12 volts voltages to control circuit C after the rectification circuit rectification, control circuit C links to each other with relay K 1, relay K 1 links to each other with A.C. contactor, and A.C. contactor links to each other with load, and load is drawn detection line and linked to each other with relay K 2, relay K 2 links to each other with rectification circuit 2, rectification circuit 2 links to each other with control circuit C, and control circuit C links to each other with relay K 3, and relay K 3 links to each other with alarm, A.C. contactor respectively.

5 volts of voltages of rectification circuit output connect 4-and 8-port and the resistance R 1 of timer NE555, and resistance R 1 connects 2 and 6 ports of timer NE555 and the common port of resistance R 2 and capacitor C 1, capacitor C 1 ground connection respectively; Resistance R 2 links to each other with the port 7 of timer NE555 by resistance R 3, the port one ground connection of timer NE555, the port 5 of timer NE555 is by capacitor C 2 ground connection, the port 3 of timer NE555 links to each other with the base stage of triode V by R4, the emitter of triode V is by resistance R 5 ground connection, the collector electrode of triode V links to each other with relay K r, diode DW is in parallel with relay K r, relay K r one end connects the 12V output port of rectification circuit, and the other end of relay K r links to each other with relay K 1 or relay K 3.

The technology that adopts the utility model to provide can realize fault detect and warning function.Double circuit can be realized automatic conversion, when the operate as normal control circuit breaks down, standby control circuit is started working, and has guaranteed the operate as normal of load, can effectively avoid the adverse effect that breaks down and cause equipment not turn round, stop production and bring because of the operate as normal control circuit.

Embodiment

In the present embodiment, the 220V alternating current is exported 5 volts, 12 volts voltages to control circuit C after the rectification circuit rectification.

5 volts of voltages of rectification circuit output connect 4-and 8-port and the resistance R 1 of timer NE555, and resistance R 1 connects 2 and 6 ports of timer NE555 and the common port of resistance R 2 and capacitor C 1, capacitor C 1 ground connection respectively; Resistance R 2 links to each other with the port 7 of timer NE555 by resistance R 3, the port one ground connection of timer NE555, the port 5 of timer NE555 is by capacitor C 2 ground connection, the port 3 of timer NE555 links to each other with the base stage of triode V by R4, the emitter of triode V is by resistance R 5 ground connection, and the collector electrode of triode V links to each other with relay K r, and diode DW is in parallel with relay K r, relay K r one end connects the 12V output port of rectification circuit, and the other end of relay K r links to each other with relay K 1.

Relay K 1 links to each other with load by A.C. contactor.

Load is drawn detection line and is linked to each other with relay K 2, and relay K 2 links to each other with rectification circuit.

Export 5 volts, 12 volts voltages to control circuit C through the rectification circuit rectification.

Control circuit C output control signal control relay K3, relay K 3 links to each other with A.C. contactor with alarm respectively.

A.C. contactor also links to each other with three-phase alternating current.

During operate as normal by intermittent time of control circuit C and relay K 1 forming control system control circuit.When the operate as normal control system breaks down cisco unity malfunction or testing circuit when detecting fault, relay K 2 conductings, standby control circuit C enters operating state automatically, the intermittent time of beginning control circuit, K3 conducting simultaneously, alarm sends alarm signal.Staff's on-call maintenance operate as normal control system simultaneously, and do not influence the load operate as normal.
