Description

Intelligence auto-cut-off type power down switch

Technical field

The utility model relates to a kind of power down switch, is specifically related to a kind of intelligent auto-cut-off type power down switch.

Background technology

At present, most of consumer is all generally that regular tap connects power supply and computer as computer etc., controls the opening and closing of computer thus.In life, computer is very universal, some are when closing computer, often only custom seldom initiatively pulls out attaching plug shut down of computer, and at this moment power transformer, display screen etc. are in a kind of state (hereinafter referred to as low power consumpting state) of low-power consumption, still at consumption electric energy." small " power consumption that the consumer being in this low power consumpting state in a large number consumes takes care of the pence, and will cause huge waste of energy, and there is potential safety hazard.Therefore, design a kind of intelligent auto-cut-off type power down switch, when the consumers such as computer are in low power consumpting state, power down switch automatically controls circuit and cuts off the electricity supply, and reaches saves energy, gets rid of the object of potential safety hazard.

Utility model content

The utility model proposes a kind of intelligent auto-cut-off type power down switch, comprise combined switch, relay, current sampling unit, control power supply, single-chip microcomputer.Accessing power supply after described combined switch, relay parallel connection, connects with current sampling unit in one end; Connect with current sampling unit after controlling power supply and computer parallel connection; The current signal of single-chip microcomputer received current sampling unit Real-time Collection.

In described current sampling unit, current transformer is installed, current sampling unit by the current signal transfer of Real-time Collection in circuit to single-chip microcomputer.

Described Single-chip Controlling relay, by mcu programming, analyzes the current signal in circuit; Current signal when computer is in low power consumpting state in circuit is more weak than current signal during its normal work, when current signal is less than certain setting value, power supply disconnects by Single-chip Controlling relay, thus completes the intelligent automatic power-off control of power down switch to circuit.

When described current sampling unit is to single-chip microcomputer transmission weak current signal, single-chip microcomputer starts timing, and continue to judge to current signal, if when the current signal within the timing stage set is less than certain setting value, now power supply disconnects by Single-chip Controlling relay always within the timing stage of setting; Otherwise, this weak current signal is considered as the dormancy of computer short time causes, this circuit state is not reacted, thus avoid the false judgment that causes power supply to disconnect because the dormancy of computer short time causes current signal to weaken.

The beneficial effects of the utility model:

1, by by relay, current sampling unit and microcontroller unit, the Intelligent Measurement to circuit state and control is achieved;

2, by designing different current critical values to mcu programming, completing the detection of different circuit current signal and the control to different circuit state, being applicable to the circuit of various consumer, practicality and strong adaptability;

3, single-chip microcomputer adopts the method work of timed process, effectively prevent the erroneous judgement of power down switch to circuit state, improves the reliability of power down switch;

4, the utility model principle is simple, can Intelligent Measurement, the auto-breaking of realizing circuit, has significant energy-saving effect.

Embodiment

Below in conjunction with accompanying drawing, intelligent auto-cut-off type power down switch of the present utility model is described in further detail.

Intelligence auto-cut-off type power down switch, comprises combined switch, relay, current sampling unit, control power supply, single-chip microcomputer.

Reset type switch is connected in circuit with after relay parallel connection; Reset type switch both can tap connection computer power, can will tap Signal transmissions to single-chip microcomputer again; Control power supply in parallel with computer, be subject to the control of reset type switch and relay simultaneously.

Manual shake-up reset type switch, connects circuit power, and computer runs; Meanwhile reset type switch taps to connect and controls power supply, and single-chip microcomputer is by controlling Power supply, and on-off control system is started working; When in circuit, computer is in low power consumpting state, current sampling unit by the weak current Signal transmissions that collects to single-chip microcomputer, single-chip microcomputer starts timing simultaneously, and continue to judge to current signal within the timing stage of setting, if the current signal within the timing stage set returns to current signal value when normally working, then single-chip microcomputer is not reacted to this circuit state, and computer normally runs; If when current signal is less than certain setting value within the timing stage set, then power supply disconnects by Single-chip Controlling relay always, thus complete the intelligent automatic power-off control of power down switch to circuit.

In addition, the manual-lock of switch is tapped by reset type switch, taps signal and reaches single-chip microcomputer, Single-chip Controlling cut-off power supply, and now computer power is closed, and controls power supply simultaneously and also closes.

After switch cuts out, reset type switch and relay all disconnect, then control system non-transformer, and now necessary manually shake-up reset type switch is connected and controlled power supply ability opening switch.
