[Embodiments of the invention]

FIG. 1 shows the system power-on/operation according to an embodiment of the present invention.
The configuration of the shutoff device is shown. In the figure, commands from a local power-on/shut-off command device 20 and a remote power-off command device 30 are supplied to the power-on/shut-off control section 10 at 5-. Then, the power on/off control section 1
0 sequentially controls a power control unit 40 having, for example, a group of SCR switches (not shown) for disconnecting the power supply membrane, in response to commands from the local on/off command device 20 or the remote on/off command device 30. . Power control unit 4011C
Various devices 5o, go, . . . , 50 constituting a system (for example, a computer system)
．． . . . are connected via 60. However, the power control section 40 turns on/off the power supplied to the control section 40 via the main power line 70 for the equipment designated by the power on/off control section 10 .

FIG. 2 shows a detailed configuration of the power on/off control section 10. As shown in FIG. The power on/off control section 10 includes an arithmetic control section 101, which is the central part of the control section 10, and a local on/off control section 101 shown in FIG.
Shut-off command device 20° Remote input/shut-off command device 30.
It has interfaces 102 to 104 corresponding to the power control unit 6-40, and a memory 105.

The memory 105 is, for example, a rewritable ROM that stores the on/off control table 106. The input/cutoff control table 106, as shown in FIG. 3, is a registration table of throw-off control information consisting of equipment name, line number, input delay time, cutoff order, and cutoff delay time. Here, the device name is the device 50 that is subject to power on/off control.
This is, for example, device identification information such as a device number or abbreviation. The line number indicates the number of the power line to which the corresponding device 50 is connected. Turn-on delay time, cut-off-i
! ! It shows the waiting time from the time when the power is turned on or shut off to the device 50 in the extended open time row until the time when the power is turned on or shut off to the next device 50. Further, the cutoff order indicates the order in which the power to the corresponding device 50 is cut off. Each piece of information such as the equipment name, line number, turn-on delay time, cut-off order, and cut-off delay time is defined for each piece of equipment 50, 60, . . . that constitutes the system. In this embodiment, the on/off control table 106
(corresponds to devices 5θ, 50, etc.)
The arrangement of each piece of on/off control information corresponds to the order in which the power is turned on to the corresponding device 5θ.

Next, the operation of one embodiment of the present invention will be explained using the local closing/cutting command device 20 or the remote closing/cutting command device 30.
Each type of command (request) is explained below.

a. Sequential mode operation (a-1) Power on Local on/off command device 20 or remote on/off
When a sequential mode input command is issued from the shutdown command device 30, an interrupt is generated in the calculation control unit 101 via the interface 102 or 103. As a result, the calculation control section 10 changes from the idle mode to the control operation mode PK.
The state changes, and first the type of the command (request) is determined.

In the case of a sequential mode entry command as in this example,
The arithmetic control unit 101 accesses the memory 105 and reads the on/off control table 1 stored in the memory 105.
Read the input/cutoff control information at the beginning of 06. Next, the arithmetic control unit 101 outputs the line number in the closing/cutting control information to the interface 104 together with the closing command after the closing delay time indicated by the closing/cutting control information has elapsed. Next, the arithmetic control unit 101 converts the on/off control table 1
06, and outputs the next line number and input command to the interface 104 after the shutdown delay time indicated by the information has elapsed. Below, 3
The operation similar to the above-mentioned operation is repeated for each input/cutoff control information from the th to the final input/cutoff control information, and then the arithmetic control section 10
1 returns to idle mode rVc. It should be noted that whether or not the input/interruption control information is the final input/interruption control information can be determined by, for example, whether or not the input/interruption control information added to the input/interruption control information is "1".

On the other hand, the line numbers and input commands that are sequentially output from the arithmetic control section 101 to the interface 104 are transmitted from the interface 104 to the electric power billing section 4o17c. When the power control unit 40 receives the line number and power-on command from the interface 104, the power control unit 40 controls the power supplied via the main power line 70.
The power is supplied to the corresponding device 50 via the power line 60 indicated by the line number. The timing of turning on the power is when the voltage phase of the power supply is 06. This is to prevent rush current.

(a-2) When a sequential mode shutdown command is issued from the power supply shutoff local power on/shutoff command device 20″! and remote power on/shutoff command device 30, the interface 102 or Ios
An interrupt occurs in the VC calculation control unit 101. Accordingly, the calculation control unit 101 determines the type of the command. In the case of a sequential mode shutdown command as in this example, the ON/OFF control table 1 stored in the memory 105
06 and extracts the on/off control information indicating the first cutoff order. Next, the arithmetic control unit 101 outputs the line number in the closing/cutting control information to the interface 104 together with the closing command after the 10-blocking delay time indicated by the closing/cutting control information has elapsed. Next, the arithmetic control unit 101 searches the closing/cutting control table 106 again, extracts closing/cutting control information indicating the second shutting order, and issues the next line number and shutting command after the shutting delay time indicated by the information has elapsed. is output to the interface 104. Thereafter, the same operations as those described above are repeated for the closing/cutting control information indicating the third shutting order to the closing/cutting control information indicating the Saihiragi shutting order. Hiko, whether or not it is the final closing/cutting control information can be determined by, for example, whether or not the closing end bit added to the closing/cutting control information is "1." This cutoff end bit and the input bit become unnecessary if a directory section indicating the number of input/cutoff control information (number of entries) registered in the input/cutoff control table 106 is provided.

b. Independent mode operation (b-1) Power on Local on/off command device 20 or remote on/off
When a single mode P power-on command indicating power-on of a specific device is issued from the cut-off command device 30, an interrupt is generated in the arithmetic control unit 101 by the interface 102 or 103.

As a result, the arithmetic and control unit 101 makes a state transition from the idle mode r to the control operation mode r, and first determines the type of the command (request). In the case of a single mode P power-on command as in this example, the arithmetic control unit 101 uses the pitch control table 106 stored in the memory 1ρ5 as the device name indicating the power-on target device added to the command. Search using . The arithmetic control unit 101 extracts the on/off control information corresponding to the device to be powered on from the toilet control table 106 and outputs the line number indicated by the information to the interface 104 together with the on command. The subsequent operations are performed in the same manner as a and (a-1) above.

(b-2) Power cut off Local power on/Shutdown command device 20 or remote power on/
When a single mode power cutoff command indicating power cutoff to a specific device is issued from the cutoff command device 3θ, an interrupt is generated in the arithmetic operation control unit 101 via the interface 102 or 103.

After this, the arithmetic control section 10 makes a state transition from the idle mode r to the control operation mode, and first determines the type of the above-mentioned command. In the case of an individual motor 9 power cutoff command as in this example,
The arithmetic control unit 10 searches the on/off control table 106 stored in the memory 105 using the device name indicating the device to be powered off, which is added to the command.

Therefore, the arithmetic control unit 101 uses the on/off control table 1
06, and outputs the line number indicated by the information to the interface 104 along with a shutdown command. The subsequent operations are performed in the same manner as a and (a-2) above.

Next, a description will be given of how to deal with changes or expansions in the system configuration. In this case, each piece of information such as the device name, line number, turn-on delay time, cut-off order, and cut-off delay time is defined for each device configuring the system after modification or expansion, and a new turn-on/shut-off control table 10 is created.
6 is stored in the memory 105Vc. From doing this K,
In other words, the input/cutoff control table 1 in the memory 105 (
By rewriting the contents of θ6) according to the new system configuration, flexible system power-on/off control can be performed according to the system configuration.

Furthermore, according to this embodiment, the power can be sequentially turned on/off and individually turned on/off to each device constituting the system, thereby improving maintainability. Moreover, according to this embodiment, even if the installation location of the insect system is busy,
Since the power can be turned on and off even from a distance other than the installation location, maintainability is further improved.

In addition, in the above embodiment, the arrangement of the on/off control information in the on/off control table was explained as matching the order of powering on the corresponding equipment in 14-, but this is not limited to this. .

For example, it is possible to set information indicating the order in which the power is turned on in the power-on/shut-off control information. Further, the arrangement of the on/off control information may be made to match the order of power off. In this case, it is necessary to replace (information indicating) the shutoff order in the closing/cutting control information with (information indicating) the closing order.

Further, in the embodiment described above, the on/off control information has been described as including information indicating the power cutoff order and the cutoff delay time, but these pieces of information are not necessarily necessary.

In addition, the memory that stores the on/off control table is not limited to rewritable ROM K, but also, for example, writable ROM.
, or a mask ROM. In this case, although the degree of freedom is less than when using a rewritable ROM, it is more flexible than before because it is sufficient to use a ROM that has a table according to the system configuration.

Furthermore, in the embodiment described above, a case has been described in which the power control section has the function of determining the power line indicated by the line number and identifying the on/off command, but these functions may be implemented as an interface to the power control section. It may be made to lean.

In other words, the interface to the power control section may be provided with a line number decoding P function, and an output signal from the interface may turn on/off an SCR switch or the like in the power control section to 0N10FF. It should be noted that the present invention is of course applicable not only to electronic computer systems but also to any system comprising a large number of devices.

〔Effect of the invention〕

As described in detail above, according to the present invention, it is possible to have a simple configuration and yet provide flexible power supply/on/off according to the system configuration.
Can be blocked.
