The computer host machine provided with the function of intelligently controlling power-on and power-off of the peripheral comprises a main machine controlled direct-current power supply connected with an alternating-current power plug, wherein an auxiliary direct-current power circuit is connected on the alternating-current power plug. The output end of the auxiliary direct-current power circuit is connected on the power supply input end of a relay controlled driving circuit. The host machine controlled direct-current power supply or a computer mainboard or a computer accessory is connected with a voltage sampling circuit, and the output end of the voltage sampling circuit is connected with the control signal input end of the relay controlled driving circuit. The voltage output end of the relay controlled driving circuit is connected with the driving end of a relay, one alternating-current contact of the relay is connected on the live wire of the alternating-current power plug, and a computer auxiliary external power plug is arranged between another alternating-current contact of the relay and the zero ling of the alternating-current power plug. The computer host machine provided with the function of intelligently controlling power-on and power-off of the peripheral can enable standby power consumption to tend to zero.
Description
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 said ac power plug, connecting the auxiliary direct current source circuit; Two dc output ends of said auxiliary direct current source circuit are connected the power input of the controlled driving circuit of a relay; On the controlled direct supply of main frame or computer main board or computer fittings, connect voltage sample circuit; The output terminal of said voltage sample 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 relay, and 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 auxiliary DC power supply of the utility model is that controlled driving circuit of relay and relay provide DC voltage, and the controlled driving circuit of relay is controlled by the launch computer and the shutdown signal of the controlled direct supply of main frame or computer main board or computer fittings output.When host computer startup work; Controlled direct supply of main frame or computer main board or computer fittings have WV, and its WV of voltage sample circuit sampling is exported to the controlled driving circuit of relay; The power supply that computer is assisted peripheral hardware is connected in the conducting of driving circuit pilot relay; When computer is in standby, sleep or shutdown; Controlled direct supply of main frame or computer main board or computer fittings do not have WV; The voltage sample circuit sampling is given the controlled driving circuit of relay less than its WV, and the driving circuit pilot relay breaks off, and cuts off the peripheral hardware power supply; 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.
