Description

A kind of intelligent appliance stand-by energy-saving socket

Technical field

The utility model relates to a kind of socket, especially a kind of energy-saving socket for home appliances in standby state of intelligence.

Background technology

Household electrical appliance have generally been applied remote control standby function at present, and in the situation that household electrical appliance mains switch is not closed, the infrared radiation receiving circuit of household electrical appliances inside is still in running order, and therefore under holding state, household electrical appliance also will consume electric energy.Generally, the consumed power of holding state is 10% left and right of its open state consumed power, approximately 5-15 watts.The more complete town dweller of household electrical appliance is about power consumption 20-40 kilowatt hours of family appliance standby monthly on average.When especially the device standby time is far longer than service time, its waste of energy phenomenon is more serious, and the power consumption under household electrical appliance holding state is appreciable.

Summary of the invention

The utility model is for above-mentioned technical deficiency, a kind of intelligent appliance stand-by energy-saving socket is provided, when household electrical appliance use this female type, socket can detect an electrical power automatically, and household electrical appliances in working order time, guarantee the power supply of household electrical appliances normal operation, when household electrical appliances enter holding state, electrical equipment mains supply is just cut off in time delay automatically after 2 minutes, eliminate family appliance standby power consumption, plays energy-conservation object.The utility model is achieved through the following technical solutions, and intelligent appliance stand-by energy-saving socket mainly consists of voltage changing module, holding state detection module, control module, between 3 modules, all connects.The function of voltage changing module be by 220V AC voltage conversion for+5V and+direct voltage of 12V, and be that holding state detection module and control module are powered.Holding state detection module is the power detection comparison circuit of electrical equipment, power according to electrical equipment during in working order with holding state is different, when the main limit of current transformer electric current flows through electrical equipment, on its induction limit, can produce induced current, through transformation, rectification, filtering, amplification, then with reference to standby voltage comparison, output electrical equipment working state signal to control module.Meanwhile, receive the control signal of being sent here by control module, according to control signal, control the closed of LED, loudspeaker and relay or open, and then controlling household electrical appliances power supply, reach energy-conservation object.Control module is single-chip microcomputer, receives the electrical work status signal that holding state detection module sends, and judges, output relay control signal, LED control signal and loudspeaker control signal are to holding state detection module.

The utility model can cut off electric equipment by Single-chip Controlling can freely arrange cut-out time delay according to dissimilar household electrical appliances with being connected also of power supply, reduces the energy waste producing because of stand-by power consumption.The utility model can also be monitored power supply and operating voltage state, when occurring when abnormal, also can cut off being rapidly connected of electric equipment and power supply, with protective device equipment.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.

In Fig. 1, the utility model comprises voltage changing module, holding state detection module, control module.Provide+5V of voltage changing module and+direct voltage of 12V is holding state detection module and control module power supply.Holding state detection module detects and exports the working state signal of electrical equipment to control module.Control module receives the electrical work status signal that holding state detection module sends, and judges, to holding state detection module output relay control signal, LED control signal and loudspeaker control signal.Holding state detection module is controlled the closed of LED, loudspeaker and relay or opens according to control signal, and then controls household electrical appliances power supply.

Figure 2 shows that holding state detection module circuit diagram.Holding state detection module utilizes current transformer senses flow to cross main coil current, in induction coil, can produce induced current, by resistance R 1, convert the current signal of induction to voltage signal, through rectifier diode D1, ac voltage signal is converted to d. c. voltage signal, the Π type filter circuit that the dividing potential drop forming through resistance R 2, R3, R4 and capacitor C 1, C2 resistance R 5 form converts d. c. voltage signal to effective value voltage, and this signal is enlarged into faint direct current signal through operational amplifier A R1 the voltage signal being easily detected.AR1 output end voltage signal is sent into comparator AR2, compares, with characterizing the threshold voltage of household electrical appliances in holding state when being greater than threshold voltage, show that electrical equipment is in normal operating state, output output 0V magnitude of voltage, on the contrary show that electrical equipment is in holding state, output 12V magnitude of voltage.The output voltage signal access photoelectronic coupler U1 of comparator AR2, U1 is comprised of light-emitting diode and phototriode, when AR2 output 0V voltage, in diode, there is electric current to pass through, LED lighting irradiates phototriode makes triode conducting, U1 is to control module output 0V low level signal, otherwise when AR2 exports 12V voltage, U1 is to control module output 5V high level signal.

Fig. 3 is control module flow chart.Single-chip microcomputer in control module receives after the voltage signal that U1 sends here, sends the control signal of controlling buzzer, LED, relay according to program.Idiographic flow is: after system powers on, single-chip microcomputer completes initial work, exports 3 control signals: 1. LED light is lighted, 2., by the relay UNICOM of control apparatus power supply, 3. loudspeaker send prompt tone to holding state detection module.Single-chip microcomputer is opened after time delays in two minutes of electrical equipment for using the personnel of household electrical appliances to continue to employ in advance remote control, single-chip microcomputer starts the electrical work status pin signal that judges that holding state detection module is sent here, if this pin is high level, represent that electrical equipment is in holding state, output control signal disconnects the relay of control apparatus power supply, loudspeaker send prompt tone, and LED light is extinguished.If this pin is low level, represent that electrical equipment is in running order, output control signal makes LED flicker, continue repeatedly to detect this pin level, until this pin is high level, output control signal is extinguished LED light, for the misoperation that prevents that electrical equipment instant cut-off that external electrical network fluctuation causes from causing, after time delay 30 seconds, again judge this pin, as be low level, the interference that the fluctuation of expression external electrical network causes, again allow LED glimmer, and continuation detects this pin, if pin is still high level, think that electrical equipment has entered holding state, output control signal disconnects the relay of control apparatus power supply, loudspeaker send prompt tone, LED light is extinguished.

The utility model plug is connected on 220V mains supply, household electrical appliances attaching plug is inserted on socket of the present utility model.Press shift knob, household electrical appliances can normally be used.When closing household electrical appliances with remote controller, after 2 minutes, will automatically cut off household electrical appliances power supply.
