Abstract
The utility model provides a computer host with an intelligent control of a peripheral power on and power off function and relates to the technical field of computer host production. The computer host with the intelligent control of the peripheral power on and power off function comprises a host controlled direct current power supply which is connected with an alternating current power plug. A low voltage direct current output end of the host controlled direct current power supply is connected with the computer host and computer accessories, and the low voltage direct current output end of the host controlled direct current power supply is further connected with a drive end of a relay. A communication contact of the relay is connected on a firewire of the alternating current power plug, and computer aided peripheral power jacks are connected between another communication contact of the relay and a null line of the alternating current power plug. When the computer host is started to work, the host controlled direct current power supply outputs low voltage direct current to control the relay for breakover, so that a computer aided peripheral power supply is powered on automatically. When a computer is in standby, sleeping or shutdown, the host controlled direct current power supply does not output the low voltage direct current and the relay is disconnected, so that corresponding peripheral power supplies can be cut off timely and effectively and standby energy consumption is close to zero.
Description
Technical field
The utility model belongs to the Intelligent electrical 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 (such as display, sound equipment and printer etc.) is still in running order, when not using computer, need to manually cut off the power supply.
Through retrieval, two kinds of computer special intelligent breaker devices are arranged at present: 1, a kind of computer dedicated energy-saving socket, when host computer shuts down, can intelligence disconnect the computer-aided external power, mu balanced circuit, digital operational amplification circuit are set, single-chip microcomputer treatment circuit, relay etc. in the Socket casing, mainly by judging the size of main frame electric current, intelligence switches on and off the power supply of computer-aided peripheral hardware (such as display, sound equipment and printer etc.) to this smart jack.2, also have in addition a kind of computer dedicated energy-saving electric power connection line, 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 dedicated energy-saving socket and computer dedicated energy-saving electric power connection line have its intrinsic defective: 1, mu balanced circuit, digital operational amplification circuit are arranged in its housing, the single-chip microcomputer treatment circuit, relay etc., no matter whether computer is in the use state, these circuit must be always in running order, owing to factors such as the impact that is subjected to for a long time external voltage and components and parts life-spans itself, circuit is easy to damage.2, there are mu balanced circuit, digital operational amplification circuit in described energy-saving socket and energy-saving electric power line inside, the single-chip microcomputer treatment circuit, and relay etc., because it is in running order for a long time, circuit itself has also produced certain standby energy consumption.
Summary of the invention
For the problems referred to above, the purpose of this utility model provides a kind of host computer with automatic control electric brain peripheral hardware power on/off function, 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, the low-voltage direct output terminal of the controlled direct supply of described main frame also is connected with the drive end of a relay, one of described relay exchanges the contact and is connected on the live wire of ac power plug, exchanges at another of described relay between zero line of contact and ac power plug to connect computer-aided external power jack.
At least two of described computer-aided external power jacks, each computer-aided external power jack is parallel with one another.
The power supply access plug of the computer-aided peripheral hardwares such as former display, sound equipment and printer is directly inserted on the computer-aided external power jack that is arranged on the mainframe box.When host computer startup work, the power supply of computer-aided peripheral hardware is connected in the conducting of the controlled direct supply of main frame output 5V or 12V low-voltage direct pilot relay automatically; When computer is in standby, sleep or shutdown, the controlled direct supply of main frame is not exported 5V or 12V low-voltage direct, relay disconnects, and can in time, effectively cut off respective perimeter device power supply (DPS) (such as display, sound equipment and printer etc.) like this, and standby energy consumption is gone to zero.
The utility model is owing to taking above technical scheme, and it has the following advantages:
1, owing to utilizing conducting and the disconnection of the low-voltage direct pilot relay of the controlled direct supply of main frame output, to compare with existing computer energy-saving socket etc., circuit is simple, and is safe and reliable, long service life.
2, when computer was in standby, sleep or shutdown, the controlled direct supply of main frame is output dc voltage not, and relay is not worked, so do not consume electric energy during the standby of circuit of the present utility model own, stand-by power consumption is zero.
