Background technology

Computer is as the essential product of modern handle official bussiness and family, bring great convenience to office automation and all families, but standby in modern handle official bussiness and family's use procedure to take electricity serious, most of user is only that the shut-off function that microsystem provides is shut down computer after using microcomputer, the direct result done like this is waste electric energy, also aggravate the aging of computer power and display power supply simultaneously, also make microcomputer easily suffer in no situation from the unnecessary interference of electrical network and infringement in addition.According to investigations, China's family appliance standby phenomenon is very general, the family of nearly seventy percent is had to use after computer not powered-down, through measuring, about about 10 watts of every platform computer standby power consumption, calculated according to standby 10 hours of every day, 1 year every platform computer waste electric energy 36.5 degree, this will calculate national all computers, and only stand-by power consumption just reaches over ten billion degree.For this present situation, existing production can save the socket of the energy, and wherein a kind of is the load utilizing inspection leakage resistance test socket, when being less than certain power, close the electrical appliance on socket, but be less than the electrical appliance detecting minimum value, just can not use on this socket; Another kind is exactly the power utilizing electrical appliance in inspection convertor transformer test socket, and this exists the problems referred to above equally, simultaneously above two kinds of designs, and minimum power design allows user come, and so often causes just truly to show automatic shutdown.The jack design one-tenth Single-chip Controlling had in addition, this socket antijamming capability is more weak, simultaneously design R&D costs and cost of manufacture higher.

Utility model content

The utility model object is the deficiency overcoming prior art existence, provides a kind of microcomputer private jack with online or complete isolated control.

The technical solution of the utility model is achieved in that a kind of microcomputer private jack, comprise the socket box body be made up of panel, housing and the socket power control circuit be arranged in box body, it is characterized in that: mains supply is through transformer B1, again through rectifier BR1 rectification, electric capacity C1 filtering changes alternating current into direct voltage, and it is that socket power control circuit is powered that this direct voltage forms burning voltage through three terminal regulator IC2; Burning voltage is tied through the be of triode T1 simultaneously, resistance R3, resistance R1 charge to electric capacity C2, and the electric current in the be knot of triode T1 makes triode T1 conducting, relay J 1 adhesive, and socket CN1 starts power supply, and whole microsystem is in running order; The USB port of control circuit connects with the USB port of microcomputer, by photoelectrical coupler IC1 and through R3 make triode T1 maintain conducting state.

The complete isolated control circuit that the utility model designs on online control circuit basis: mains supply connects button AN2 by switch J1-1, button AN2 is connected in parallel on the two ends of switch J1-1, and it is that socket power control circuit is powered that button AN2 forms stable 12V voltage through transformer B1, rectifier BR1, electric capacity C1, voltage through IC2.

The control circuit of another kind of complete isolated increase accurate timing: mains supply connects button AN2 by switch J1-1, button AN2 is connected in parallel on the two ends of switch J1-1, AN2 through transformer B1, rectifier BR1, electric capacity C1, to form stable 12V voltage through three terminal regulator IC2 be again that socket power control circuit is powered; Pressurizer IC2 output voltage, through J1 and timer NE555, is respectively relay and timer is powered, and by timer NE555 direct control switch J1-1, J1-1 connection control socket CN1, NE555 contact resistance R1, electric capacity C2 realize accurate timing.

Design advantage of the present utility model: this microcomputer private jack, whether shut down by detection microcomputer and determine whether closing general supply, user or microcomputer software are after shut down of computer, this circuit cut off computer and all auxiliary device power supplys completely within 30 second time, comprise computer, display, printer, audio amplifier, modulator-demodulator, router etc., so have more advantage from economize on electricity aspect; Meanwhile, after the design's shutdown, by all devices and mains isolation, prevent from raising suddenly because of line voltage or being struck by lightning and damage equipment.In computer operation, this socket also has following characteristics: 1, need not manual-lock total power switch; 2, after user starts supply socket, after a period of time, (30 ~ 90S) be not if start microcomputer, and the circuit of socket inside will close general supply; 3, after user starts supply socket, (30 ~ 90S) start-up simulation machine at the appointed time, socket normal power supply; 4, after user finishes using microcomputer, only need Shutdown Hosts, the control circuit of socket inside can cut out general supply in certain hour (30 ~ 90S); 5, control circuit power consumption hardly in the standby state; 6, design on control circuit is simple, and failure rate is extremely low;
