Description
Affiliated technical field
The utility model relates to energy-conservation socket, especially refer to a kind of energy-conservation socket that can set power-down mode, this socket can be real-time the controlled wiring board of detection on power consumption equipment or the electricity consumption situation of electronic product, when being complementary, then cut off the power supply of controlled wiring board automatically, to reach energy-conservation purpose with the power-down mode that sets.
Background technology
Each electronic product has been the indispensable product of life; but to the utilization of power supply but is unusual waste; because a large amount of use Switching Power Supply; power transformer and various standby mode; immediately when need not using, these products also consuming electric energy endlessly; and a socket often is connected to multiple electricity consumption product in daily use; as the TV in the parlor; DVD; digital television case; game machine; power amplifiers etc. are used same power supply wiring board usually; usually close other electrical equipment when television set and just do not had necessity of energising; therefore we wish when television set enter close or during standby the power supply of other relevant electrical equipment also can be cut off; and current employed on the market supply socket or terminal block only provide simple power supply transfer function and simple hand switch function; can't identify product is to use or do not re-use; power-down mode can not be set remove to judge certain or certain the several power consumption equipments auto power off under specific electricity consumption combination that is subjected on the control socket, thereby can't realize the energy-conservation and convenient purpose of using.
Summary of the invention
The purpose of this utility model provides a kind of energy-conservation socket, can power-down mode be set according to the electricity consumption on controlled wiring board combination, and automatic disconnection power supply when the power consumption equipment on the controlled wiring board reaches set outage mould is to realize energy-conservation purpose.
Another purpose of the present utility model is self to realize energy-conservation, and no matter himself the static power consumption of the whether break-make of controlled wiring board remains in the 1mA--10mA.
For realizing above purpose, energy-conservation socket of the present utility model, it comprises, a housing, at least one socket is used to patch controlled wiring board on it, two buttons are arranged on the housing, and S1 is used to open controlled wiring board and S2 is provided with power-down mode usefulness, and indicator light LED1 is used for indication and cuts off the power supply-switch on-three states of power-down mode are set.
EEPROM (U5) is arranged in its shell by power transformer T1, voltage stabilizing circuit, current transformer T2, operational amplification circuit U2, microprocessor U4, magnetic latching relay Z1, drive circuit of magnetic latching relay U3.
Its circuit structure and operation principle are (with reference to figure 1, Fig. 2): one road civil power is through power transformer T1, voltage stabilizing circuit provides+5V voltage for operational amplification circuit U2, microprocessor U4, for drive circuit of magnetic latching relay U3, magnetic latching relay provide+driving voltage of 12V.
Another road civil power live wire is wire-wrapped in current transformer T2, receives on magnetic latching relay switch 1 pin again, and magnetic latching relay switch 2 pin are linked on the live wire of socket, and zero line and ground wire directly are linked on the zero line and ground wire on the socket.
Instrument transformer T2 changes into voltage through full-wave rectification, resistance R 3 with the magnitude of current with induced current and delivers to operational amplification circuit, voltage after operational amplification circuit will amplify is delivered to microprocessor U4, microprocessor U4 carries out the A/D conversion to the voltage of input, changes into digital quantity and handles.
This energy-conservation socket disconnects the power supply of controlled wiring board when powering on, indicator light LED1 goes out, retaining is pressed S1, and hold and continue 1 second the time, be controlled wiring board energising, this moment microprocessor U4 can every interval the current value that induces by mutual inductance receiver T2 of 1 second once sampling, and compare with the current value that when power-down mode is set, is kept among the EEPROM (U5), when the current value preserved when power-down mode is set, then compare success, and then the controlled wiring board power supply of automatic disconnection after delaying time 8 seconds.
It is (to make its energising if do not switch on then press S1) under controlled wiring board energising situation that power-down mode is set, electrical appliance on the controlled wiring board is changed to the state of wishing outage, pressing S2 again is provided with, this moment can sample the repeatedly electricity consumption current value of current controlled wiring board of microprocessor, but be saved among the EEPROM (U5), end is set when LED1 flicker 2 times.Illustrate: we expect that such one is combined into current automatically cutting off power source when television set standby, DVD standby, power amplifier start, we can be changed to standby with television set so, DVD is changed to standby, amplifier power supply is opened, connect down then power-down mode button S2 is set, success is set when LED1 flicker 2 times.
Energy-conservation socket self Design of power saving one is when controlled wiring board is in outage, this energy-conservation socket can enter into energy saver mode automatically, be that microprocessor does not carry out the A/D sampling, putting drive circuit of magnetic latching relay is energy-saving mode, and microprocessor self also enters sleep pattern.Because two kinds of patterns of magnetic latching relay switch all mustn't keep electric current, only when changing, its state need one 500 milli to claim left and right sides switching current just now, therefore this energy-conservation socket its quiescent dissipation very low all whenever.
The major advantage that the utility model can be provided with the energy-saving electric power socket of power-down mode is: 1) do not contact directly with civil power, and safe, and do not influence the electricity consumption loop of controlled electric equipment.2) energy-conservation socket oneself power consumption can both keep low-down level at any time, solves self problem of energy saving.3) power-down mode can be set arbitrarily easily, can adapt to different electrical equipment, and the combination of electrical equipment, and good generality, versatility are arranged, and better, realizes purpose of energy saving more easily.4) controlled wiring board can be the product of any producer, and the user can select according to the hobby of controlling oneself.
