Description
Affiliated technical field
The present invention be a kind of can be by the computer power socket of computer program control, be used to peg graft host computer and peripheral hardware provide the power supply control to each computer peripheral equipment.
Technical background
Along with the progress of society, it is universal day by day that computer has become, and the peripheral hardware of computer constantly increases, such as display, and multimedia loudspeaker box, printer, scanner or the like.Be used for doing the supply socket of computer and peripheral hardware thereof at present, common universal power supply socket arranged and have the automatic control socket that electricity consumption is monitored to main frame, as patent 99100821.9.
Common blanket socket only provides simply and is electrically connected, and the shortcoming of existence is:
1. each computer peripheral equipment of pegging graft all needs the hand switch power supply.When the position that computer peripheral equipment is put is far away, seem inconvenient especially.And each switch computer all will be carried out the repetition mechanical action of each computer peripheral equipment power supply of switch.
2. manual operation switch for the computer with software shutdown function, is forgotten the situation of closing other peripheral hardware power supply after closing host computer easily, causes unnecessary waste.
3. present computer has the function of software shutdown more, and computer peripheral equipment does not have this function substantially, and this causes the effect and the notion of software shutdown not to be given full play to.
Electricity consumption is monitored to main frame, come the automatic control power supply of switch computer peripheral equipment, mainly utilize and in host computer supply line, establish an inductive coil, judge that according to the size of current of inductive coil host computer is in open state or off-mode, open synchronously or the power supply of closeall computer peripheral equipment.The shortcoming of this power supply be can not according to external unit whether needs make be used for carrying out power supply respectively and control in real time.The host computer computer peripheral equipment start of also switching on of starting shooting is then used for not needing in this task; Or temporarily need not use, just need after a period of time to use; Or temporary needs use, and do not need the computer peripheral equipment that uses after a period of time again, are a kind of waste equally.
Summary of the invention
In order to address the above problem, the present invention provide a kind of can be by the computer power socket of computer program control.Host computer and peripheral hardware are plugged on the socket of the present invention, when host computer is started shooting, and the synchronous energized of the display of computer, other computer peripheral equipment keeps off-position.After computer entered operating system, the user can come other peripheral hardware is carried out random switch by Control Software.After the host computer shutdown, all computer peripheral equipments are closed power supply simultaneously.
To achieve these goals, the present invention is a kind of can be is characterized in that by the computer power socket of computer program control: by data line, power control constitutes, and data line one end connects power control, can the peg graft output port of computer of the other end.By the control of computer program, can control power control and open or close corresponding power supply supply output port.Data line can be a Serial Port Line, the serial ports of grafting computer; Or the parallel port line, the parallel port of grafting computer; Or the USB line, the USB mouth of grafting computer.The break-make that power control is controlled each switch according to the level state or the output data of the pin of above-mentioned output channel port.
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a functional-block diagram of the present invention.
Fig. 2 is the circuit theory diagrams of first embodiment of the present invention
Fig. 3 is the circuit theory diagrams of second embodiment of the present invention
Fig. 4 is the circuit theory diagrams of the 3rd embodiment of the present invention
First embodiment, the output port of computer adopts serial ports, sees Fig. 2,1. computer serial ports, 2. power control, 3. input power supply.Computer serial ports 1 is connected with power control 2 by Serial Port Line.Serial Port Line is drawn four lines from the serial ports of computer and is given power control 2, and they are respectively the TXD of serial ports, RTS, DTR, GND.Power control 2 is by optical coupling isolator V1, V2, V3, bidirectional triode thyristor V4, V5, V6, and socket P1, P2, P3 form.TXD is connected optical coupling isolator V1 input end with GND.When computer is in off-mode, there is not voltage between TXD and GND, not conducting of optical coupling isolator V1, yet not conducting of bidirectional triode thyristor V4, socket P1 outage; Work as booting computer, TXD produces negative voltage to GND, and this voltage makes optical coupling isolator V1 conducting, also conducting of bidirectional triode thyristor V4 as a result, and socket P1 gets.This socket mainly provide to need with the computer peripheral equipment of the synchronous start and stop of host computer, as display.Optical coupling isolator V2, V3 are connected with RTS, DTR respectively, simultaneously another termination GND.When computer was in off-mode, RTS, DTR GND did not over the ground have voltage.Optical coupling isolator V2, not conductings of V3, bidirectional triode thyristor V5, also not conducting of V6, socket P2, P3 outage; After booting computer enters operating system, can programme to RTS, DTR by computer, control their level state, thereby make optical coupling isolator V2, V3 conducting or end, thereby make bidirectional triode thyristor V5, V6 conducting or end, thereby control socket P2, P3 power supply or outage.These two socket P2, P3 offer those to wish can to open at any time or the computer peripheral equipment of powered-down, as multimedia loudspeaker box.Socket P4 directly is connected with the input power supply, and is uncontrolled, offers host computer and uses.
Second embodiment, the computer output port adopts the parallel port of computer, sees Fig. 3,1. computer parallel port, 2. power control, 3. input power supply.The computer parallel port is connected with power control 2 by the parallel port line, and power control 2 is by optical coupling isolator V1, V1, V3, V4, bidirectional triode thyristor V5, V6, V7, V8, socket P1, P2, P3, P4 composition.The data pin D0 of the optical coupling isolator of power control 2 and computer parallel port, D1, D2, control pin/AUTOFD links to each other, by computer program the level of these pins is controlled, can make corresponding optical coupling isolator conducting or end, thereby make corresponding bidirectional triode thyristor conducting or end, thereby control corresponding socket power supply or outage.Wherein/and the AUTOFD pin is a high level in company with booting computer always, its corresponding control socket can provide power supply to peripheral hardware in company with booting computer at once.Can offer need with the computer peripheral equipment of the synchronous start and stop of host computer, as display.Socket P5 directly is connected with the input power supply, and is uncontrolled, offers host computer and uses.
The 3rd embodiment, the computer output port adopts the USB mouth of computer, sees Fig. 4,1.USB mouth, 2. power control, 3. input power supply.Computer USB mouth 1 is connected with power control 2 by the USB line, and power control is by the single-chip microcomputer U1 that is with the USB function, optical coupling isolator V1, V2, V3, V4, bidirectional triode thyristor V5, V6, V7, V8, socket P1, P2, P3, P4 composition.Computer program passes on control command by the USB mouth to single-chip microcomputer, single-chip microcomputer is according to receiving the instruction of coming from the USB mouth, output state to its I/O port is controlled, thereby make each optical coupling isolator conducting or end, thereby make each bidirectional triode thyristor conducting or end, thereby control each corresponding socket power supply or outage.Microcontroller power supply is provided by the USB mouth, uses internal oscillator.Socket P5 directly is connected with the input power supply, and is uncontrolled, offers host computer and uses.
