Description
Technical field
The present invention relates to the electric control technology, particularly electronic apparatus stand-by power consumption control technology.
Background technology
In recent years, along with the scarcity day by day of global energy, national governments are to energy problem's growing interest; European Union blue sky makes, the star of american energy and acceptance of the bid authentication center etc. have all worked out the standby energy consumption standard, carries out stage by stage, and the EuP instruction was implemented in full in 2010; The all electronic product standby energy consumptions of mandatory provision drop to below 1 watt; And need drop to later on below 0.5 watt in 4 years, China is electronic product big export country, this outlet industry to China will cause serious threat.Be challenge also be opportunity, must make the best use of time, clear away the obstacles for the outlet of the electronic product of China as early as possible.Though occurred the product of many reduction stand-by power consumptions on the market; Like " tubule man electricity-saving socket ", it has used single-chip microcomputer, container, amplifier Chinese patent ZL2006200757629 " air-conditioning electricity-saving socket ", and cost is high; Need study, be provided with, the user uses inconvenience.Versatility is not strong, can not supply to produce television set, air conditioner, STB, computer ... Manufacturer directly use.
Summary of the invention
In order to overcome the deficiency of prior art, the present invention proposes a kind of simple, the duty volume is little, with low cost, applicability strong, the standby automatic switch of reliable operation.
Technology side of the present invention is by being: the controlled signal of control executive circuit can be the button of standby testing circuit, infrared receiving circuit, termination power supply VS; The control executive circuit is made up of voltage comparator circuit and performance element; The present invention's power supply is got by the capacitance decompression rectification; " switch " of executive circuit is serially connected in the output loop of civil power L, and civil power zero line N is public ground GND.
When the input of voltage comparator circuit 4 obtains the high level from button 1 or infrared receiving terminal circuit 2; Voltage comparator circuit 4 output high level, at this moment the relay adhesive of executive circuit as obtain the big line current after the device power-up simultaneously; The standby testing circuit detects big electric current and flows through; Voltage comparator is got back from the high level of standby testing circuit, and the relay of executive circuit then continues to keep adhesive, and this electric current loses or when being decreased to certain value; The voltage comparator output low level, executive circuit loss signal and power cutoff.
The standby testing circuit is made up of amplifier IC1, resistance R 1-R4, capacitor C 1, diode D1; Treat that machine testing resistance R 1 is connected among the zero-power line N-NO; The end of R1 through resistance R 2 connect amplifier IC1-input, the other end of R1 through resistance R 3 connect amplifier IC1+input, zero-power line is public ground GND; The output of amplifier IC1 with its-resistance R 4 and capacitor C 1 that the input cross-over connection has parallelly connected, the output of amplifier IC1 through diode by just to the input of bearing to voltage comparator circuit 4.Amplifier IC1 output higher level when treating that machine testing resistance has bigger starup current to flow through; Amplifier IC1 output is than low level when having only less standby current to flow through.
Performance element can be relay, also can be controllable silicon, also can be optocoupler.
The invention has the beneficial effects as follows simple in structure, volume is little, cost performance is high, can make all family expenses that the standby phenomenon is arranged, office reduce to zero with stand-by power consumption dynamo-electric, electronic product, oneself power consumption is less than 0.2W.Be used for electricity-saving socket and can open the socket box outer casing mold in addition.
