Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a power supply control device in an information processing device.

[Prior art and its problems]

Conventionally, this type of power supply control device is equipped with a switch that indicates whether all systems are separated or combined, and when a command to turn on/off the power is given from the control console, only the designated system is turned on according to the state of the switch. It was deciding whether to carry out the instructions or to have the instructions carried out on all systems, including the own system. However, if the switches are in the same state, it is not possible to use a different device group for a closing operation from one system and a different device group for a disconnection operation, and furthermore, it is not possible to use different combinations in a system with three or more systems. The drawback was that it could not be realized.

[Purpose of the invention]

The purpose of the present invention is to eliminate the above-mentioned drawbacks by making it possible to set separation/coupling of systems independently of each other, and to change the range of operation for each system even when inputting/disconnecting instructions from one system. The object of the present invention is to provide a power supply control device that can be combined.

[Structure of the invention]

The present invention enables a power supply control device that turns on/off the power of a desired system in response to a power on/off instruction signal from a console corresponding to a plurality of systems existing in the system to operate its own system. Equipped with a circuit that can independently set the settings for receiving power on/off instruction signals from a console and sending them to other systems, and for accepting power on/off instruction signals from consoles of other systems, allowing power to be turned on between systems. /The feature is that any interlocking format of cutting is possible.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention. This power control device includes a power-on control circuit 51 and a power-off control circuit 5 connected to a power-on instruction switch 11 and a power-off instruction switch 12 provided on an operation console, respectively.
2, and transmission/reception determining circuits 10 and 20 connected to a power-on instruction switch 11 and a power-off instruction switch 12, respectively. The power-on control circuit 51 is a circuit that turns on the power of the corresponding system in response to a power-on instruction signal from the operation console, and the power-off control circuit 52 turns off the power of the corresponding system in response to a power-off instruction signal from the operation console. This is a circuit that executes the following. The transmission/reception determining circuit 10 is a circuit that determines whether or not to send a power-on instruction signal from the operation console to another system and whether to accept a power-on instruction signal from another system. It is constituted by a parallel circuit of a series circuit of the signal transmission diode 103 and a series circuit of the signal transmission enable/disable determination switch 14 and the signal transmission diode 104. The diodes 103 and 104 are connected so that their conducting directions are opposite to each other. The transmission/reception determination circuit 20 is a circuit that determines whether to transmit a power cut-off instruction signal from the console to another system and whether to accept a power-off instruction signal from another system. It is constituted by a parallel circuit of a series circuit of a signal transmission diode 105 and a series circuit of a signal transmission enable/disable determination switch 16 and a signal transmission diode 106. The diodes 105 and 106 are connected so that their conducting directions are opposite to each other.

In such a power control device, when the power-on instruction switch 11 is pressed, a power-on instruction signal is transmitted to the power-on control circuit 51. Here, if the switch 13 of the transmission/reception determining circuit 10 is in a conductive state, a power-on instruction signal can be outputted to the terminal 301 through the diode 103. On the other hand, if the switch 13 is in an open state, the power-on instruction signal cannot be output to the terminal 301.

Further, when a power-on instruction signal from another device is input to the terminal 301, if the switch 14 is in a conductive state, the power-on instruction signal can be transmitted to the power-on control circuit 51;
If the switch 14 is in an open state, the power-on instruction signal cannot be transmitted.

The same thing as described above can be said about the power cut-off instruction switch 12, the power cut-off control circuit 52, and the transmission/reception determining circuit 20, but since the operations are exactly the same, the explanation will be omitted.

FIG. 2 shows an embodiment in which the power supply control device of FIG. 1 is applied to a two-system system. In the figure, the circuit of the first system is the same as the circuit of FIG. 1, and the same elements are denoted by the same numbers. The circuits of the second system are also the same as the circuits of FIG. 1, but are given different numbers to distinguish them from the circuits of the first system. That is, 21 is a power-on instruction switch;
2 is a power-off instruction switch; 61 is a power-on control circuit;
62 is a power cutoff control circuit, 30 and 40 are transmission/reception determining circuits, 23, 24, 25, and 26 are signal transmission enable/disable determining switches, and 203, 204, 205, and 206 are signal transmission diodes. The transmission/reception determination circuits 10 and 20 of the first system are connected to the transmission/reception determination circuits 30 and 40 of the second system, respectively.

Now, switches 13 and 24 are conductive, and switch 14.
It is assumed that 23, 15, 16, 25, and 26 are all open. When the power-on instruction switch 11 is pressed from the first system, a signal is transmitted to the power-on control circuit 51, and at the same time, the signal is transmitted to the power-on control circuit 61 of the second system through the switch 13, diode 103, and diode 204° switch 24. will also be supplied. As a result, the devices of the first system and the second system are powered on.

If this is instructed from the second system, the power-on instruction signal can be transmitted to the power-on control circuit 61 of the second system when the power-on instruction switch 21 is pressed, but the switch 23.14
Since it is in an open state, this power-on instruction signal is not supplied to the power-on control circuit 51 of the first system, and only the second system is powered on.

Next, the power-off operation will be explained.

In this case, since the switches 15, 16, 25, and 26 are open, the signals from the power cut-off instruction switches 12 and 22 are only supplied to the power cut-off control circuits 52 and 62, respectively, and do not affect other systems. . In other words, only the power of the own system is cut off. As explained above, according to this embodiment, power on/off operations from any system can be set arbitrarily.

Although two embodiments of the present invention have been described above, the present invention is not limited to these embodiments (of course, various modifications and changes can be made within the scope of the present invention).

〔Effect of the invention〕

As explained above, according to the present invention, separation/coupling between systems can be set independently of each other by the transmission/reception determining circuit, so that operation can be performed even when input/disconnection is instructed from one system. It is possible to provide a power supply control device that allows ranges to be combined on a system-by-system basis.
