Description

A kind of host computer with Based Intelligent Control peripheral hardware break-make electric work ability

Technical field

The utility model belongs to intelligent electrician's technical field of electric appliances, particularly host computer, mainframe box, host power supply production technology.

Background technology

According to internal authority mechanism statistics, the computer standby energy consumption has accounted for 3%～13% of civilian power consumption, accounts for 2% of gross generation.China's computer One's name is legion, the standby energy consumption total amount is huge, even also be a considerable numeral highly paying attention to energy-conservation western countries' idling consumption.

Computer is after the main frame shutdown mostly at present, and other auxiliary peripheral hardware (like display, sound equipment and printer etc.) is still in running order, when not using computer, needs manual work to cut off the power supply.

Through retrieval, two kinds of computer special intelligent breaker devices are arranged at present: 1, a kind of computer energy-saving socket, when host computer shuts down; Can intelligence break off the auxiliary peripheral hardware power supply of computer; Mu balanced circuit, digital operational amplification circuit are set, single-chip microcomputer treatment circuit, relay etc. in the Socket casing; Mainly through judging the size of main frame electric current, intelligence switches on and off the power supply of the auxiliary peripheral hardware (like display, sound equipment and printer etc.) of computer to this smart jack.2, also have a kind of computer energy-saving electric power connection line in addition, its principle of work and power and computer energy-saving socket are similar, mu balanced circuit, digital operational amplification circuit are arranged equally, single-chip microcomputer treatment circuit, relay etc. in the housing.

Computer energy-saving socket and computer energy-saving electric power connection line have its intrinsic defective: its independently power lead, shell and control circuit must be arranged, can not make up as a wholely with host computer, increase the complicacy and the cost of product.Host computer, display, sound equipment attaching plug must insert the jack of appointment simultaneously, otherwise circuit can not be realized normal function, make troubles to use like this.

Summary of the invention

To the problems referred to above, the purpose of the utility model provides a kind of host computer with automatic controlling computer peripheral hardware break-make electric work ability, when host computer is in standby, sleep or shutdown, can effectively cut off the peripheral equipment power supply.

The utility model comprises the controlled direct supply of the main frame that is connected with ac power plug; Low-voltage direct output terminal at the controlled direct supply of main frame connects computer main board and computer fittings; It is characterized in that on the live wire of said ac power plug, being provided with the induction by current coil; The output terminal of said induction by current coil is connected the signal input part of current rectifying and wave filtering circuit, and the signal output part of current rectifying and wave filtering circuit is connected on the voltage comparator circuit; On said ac power plug, connect the auxiliary direct current source circuit, two dc output ends of said auxiliary direct current source circuit are connected to the power input of the controlled driving circuit of a relay and the power end of voltage comparator circuit; The signal output part of said voltage comparator circuit is connected the signal input end of the controlled driving circuit of said relay; The voltage output end of the controlled driving circuit of said relay connects the drive end of a relay; One of said relay exchanges the contact and is connected on the live wire of ac power plug, exchanges at another of said relay between zero line of contact and ac power plug to connect the auxiliary peripheral hardware supply hub of computer.

At least two of the auxiliary peripheral hardware supply hubs of said computer, the auxiliary peripheral hardware supply hub of each computer is parallel with one another.

The utility model mainly utilizes the size of inductive coil induction main frame electric current; Thereby export corresponding induced voltage and behind rectifying and wave-filtering, export to voltage comparator circuit; Voltage comparator circuit judges according to the size of induced voltage whether host computer works; The output control signal is given the controlled driving circuit of relay, thus the conducting of pilot relay and closing.When host computer is worked; Inductive coil is sensed bigger electric current, exports a bigger induced voltage, behind rectifying and wave-filtering, exports to voltage comparator circuit; Voltage comparator circuit judges that main frame is in running order; Export a control signal and give the controlled driving circuit of relay, the conducting of pilot relay gets the peripheral hardware that is connected on the auxiliary peripheral hardware supply hub of computer; When computer is in standby, sleep or shutdown; Inductive coil is sensed very little electric current; Export a very little induced voltage and give voltage comparator circuit, voltage comparator circuit judges that main frame is in off-mode, exports a control signal and gives the controlled driving circuit of relay; Pilot relay breaks off; Make the peripheral hardware dead electricity that is connected on the auxiliary peripheral hardware supply hub of computer, like this can timely and effective cut-out respective perimeter device power supply (DPS) (like display, sound equipment and printer etc.), standby energy consumption is gone to zero.
