Below, with embodiment the switch controlling device that is used for the remote activation computing machine of the present utility model is done further detailed description in conjunction with the accompanying drawings.
Fig. 1 is the square frame connection layout of the utility model one embodiment.
Fig. 2 is the circuit diagram of control device among Fig. 1.
Fig. 3 is the circuit diagram of control device among another embodiment of the utility model.
For make description of the present utility model more clear, understand, and be with nominal definition related in the utility model:
Main frame: the computing machine that is used to open other computing machine;
Far-end computer: the computing machine that need are opened by main frame.
In the following description, for convenience of explanation, identical parts are to represent with identical label in each accompanying drawing.
The utility model is applicable to the far-end computer with ATX power supply.Far-end computer with ATX power supply, when sending a starting impulse to the ATX power switch, the ATX power supply can start, thereby start this computing machine, the utility model then is a feature of utilizing above-mentioned ATX power supply, send an enabling signal by main frame, (a plurality of far-end computers can be arranged by being located at far-end computer, as far-end computer 1, far-end computer 2...... far-end computer n) control device on receives the enabling signal that this main frame sends, and pass through this control device and send power-on pulse for the ATX power switch, thereby realize the purpose of remote opening far-end computer.
The principle of work of this switch controlling device is as follows:
Consult Fig. 1 and Fig. 2, the signal input part 1a of this control device 111 is used to receive the enabling signal (being 12V voltage) that main frame 12 sends, and wherein, is to be connected with electric wire between main frame and the control device 111; The other end 2a of this control device 111 links to each other with the 12V voltage end of far-end computer 11, particularly, this end 2a can connect with computer motherboard on the 12V end pin of expansion slot.When far-end computer 11 started, this end 2a had 12V voltage, otherwise this end 2a does not have voltage, and triode Q1 is ended; And two ends 3a, the 4a of this control device 111 are to link to each other with the mainboard ATX power switch 112 of far-end computer 11, and this end 3a, 4a on the power switch socket, are used to start this far-end computer 11 on can insertion mainboard in parallel with computer power switch on the mainboard.
When main frame sends enabling signal (being 12V voltage), at this moment, the voltage that is added in this end 1a is 12V, but far-end computer 11 still is in the state that does not have start in the time of therefore, so end 2a does not have 12V voltage, be that triode Q1 does not have voltage because of base stage, and make the c of Q1, the e utmost point is in off state (being high impedance status), then enabling signal (12V voltage) is through the c of resistance R 2 with triode Q1, the dividing potential drop of e end, the electric current of conducting is provided for the base stage of triode Q2, make the c of triode Q2, the conducting of the e utmost point is saturated, and make ATX power switch 112 short circuits of this far-end computer 11 by rectifier 5, produce the starting impulse of far-end computer 11, make the ATX electric power starting of far-end computer, start this far-end computer 11 from face.And when far-end computer 11 started, the end 2a of this control device 111 then was added with the voltage of 12V, and this 12V voltage provides the conducting electric current for the base stage of triode Q1 through resistance R 1, makes triode Q1 conducting.When the Q1 conducting, make c, the e end of Q1 be in conducting state (being end impedance state), so make the base stage short circuit of triode Q2, triode Q2 is become by conducting end, when this far-end computer was in open state, Q1 was in conducting state always, so Q2 is in cut-off state always, even then main frame sends enabling signal for more than 12 time to this control device 111, can not make Q2 be in conducting state yet, thereby can prevent under the state of far-end computer start, to cause shutdown, the dormancy of far-end computer 11.This control device 111 can be realized instantaneous start, guaranteed can only far-end computer not open state carry out the open distal end computing machine.
Because of the socket of the mainboard ATX power switch 112 of far-end computer 11 not just, the tangible sign of negative pole, if just, negative pole connection error, to cause this device can't start far-end computer 11, therefore for making installation, easy to use, and the rectifier 5 that use is formed by four diodes, then make the two ends 3a of this control device, anyway 4a connects, the c end that can both guarantee triode Q2 is for anodal, the e end is negative pole, thereby guarantee when triode Q2 conducting, can normally start this far-end computer (principle of work of rectifier is very simple, does not repeat them here).
The voltage of above-mentioned end 1a and end 2a both can be 12V, also can be 5V or 10V, but the voltage at these two ends is when changing, and the resistance of resistance R 1 and R2 also must be done corresponding variation.
Fig. 3 is the circuit diagram of control device among another embodiment of the present utility model, and its principle of work is as follows:
In the control device of Fig. 3, be to use an integrated circuit block to replace the effect of above-mentioned two triodes and two resistance, the model of this integrated circuit block is NE555, and its menu is as follows:
The function of NE555 integrated circuit block is achieved as follows among Fig. 3: under the state of function sequence number 1, when far-end computer is not started shooting, 4 pins are low level, thus when main frame sends enabling signal, end 1b be added with 12V voltage promptly the voltage of 8 pins be 12V, 4 pins are low level, 7 pins are in on-state, make end 3b, 4b be in short-circuit condition, produce starting impulse, open the ATX power supply, thereby open far-end computer.When computing machine was opened, end 2b i.e. 4 pins was added with 12V voltage (high level), and 2 pin ground connection make the NE555 integrated circuit block be in the state of sequence number 4, so 7 pins are in off state.Thereby make this integrated circuit block reach with Fig. 2 in two triodes and two resistance identical functions.
In like manner, always be positive pole for making pin 7, and between this integrated circuit block and power switch, also be connected with a rectifier.
As mentioned above, this control device is installed respectively on many far-end computers, is then sent enabling signal, can open many far-end computers simultaneously, make remote teaching more convenient by a main frame 12.
