C. Conventional technology As the power system becomes larger and more complex, it is required to automatically collect and record information on substations in the power system and to improve the system to centrally monitor and control these information. Has been done.

Conventionally, in such a system, in most cases, two systems are divided into computer system systems and one computer is allocated to each system, and for example, one of the systems is monitored and controlled.
A system has been adopted in which actual online work such as recording is executed and the other system is made to stand by, and it has become a centralized system in which all the processing of online work is executed by one computer.

D. Problems to be solved by the invention The centralized system described above uses a single computer for all processing of online operations when multiple status changes occur in a short time such as when a system accident occurs. Since the processing is concentrated, the processing load of the computer increases rapidly and the responsiveness of the system deteriorates. In addition, when planning the system, we will select the model of the computer in consideration of the functions to be added in the future, but if an unexpected function addition is required after the system starts operating, the processing capacity of the computer in operation Since the memory size is limited, there is a limit to the expandability of functions. Furthermore, when changing the function, it is difficult to deal with it because the software must be changed significantly, and there is also a drawback that the degree of freedom of the system is small.

An object of the present invention is to provide a configuration control processing device for a function-distributed system, which is capable of improving responsiveness, improving function expandability, and increasing system flexibility.

Means for Solving the Problems The present invention includes an application execution unit, a plurality of functional processors that perform assigned processes in parallel with each other, and an application execution unit, and inputs to the functional processor. A plurality of input / output devices for giving data and / or outputting and displaying the data processed by the functional processor and a system management device for performing configuration control management related to the system configuration are combined into a local area network to form a system. Each of the functional processors belongs to one of the virtual systems to configure a plurality of series of computer system systems, and the system management device includes a virtual operation mode state of each computer system system and each functional processor. And the correspondence between these and the computer system to which they belong, and each input / output A table for configuration control is provided to describe the correspondence between the storage devices and the computer system to which they are connected, and the configuration control information created by the system management device is written to each functional processor and each input / output device. A table for configuration control and a data exchange control unit are provided.

F. Action The system management device determines the mode in which each computer system should operate at the configuration control state determination timing, the computer system to which each functional processor belongs, and the computer system to which each input / output device should be connected. The judgment result is written to all the tables at once, thereby executing the operation mode switching process of each computer system, the affiliation switching process of each functional processor, the connection switching process of each I / O device, and the data of each device. The exchange control unit determines the destination of the data output from the application execution unit by referring to the table for the configuration control of the device, and determines the reference result of the table for the data input from the outside. Originally, it is determined whether or not to incorporate the application into the application execution unit in the device.

In this embodiment, the respective devices such as the above-mentioned function processor are connected by a local area network, and the main part of the configuration is conceptually shown as shown in FIG. In this system, various processing tasks performed by a computer in a conventional two-series system are divided into functions, for example, 3
Processing the set of functional processor 1 ₁ to 1 ₃ are independent in parallel to adopt a method of performing various functions processor 1 ₁ to 1 ₃ have been respectively duplexing were subjected respectively subscripts X, the Y A number of feature processors. Here 1 ₁ to 1 ₃ of the code is a code corresponding to the component type that is assigned, also X,
The code of Y corresponds to the code within the component type. Considering a virtual two-series computer system A system and B system, one of the duplicated functional processors belongs to the A system and the other belongs to the B system. These computer systems A
One of the system and the system B is operated in a normal mode, and the other is operated in a non-normal mode such as a standby mode, a test mode and a simulation mode. Here, the normal mode is a mode for executing all online operations such as monitoring, control, and recording, and the standby mode is a standby mode so that you can always switch to the normal mode in case of system failure in the normal mode. Mode, the test mode is a mode in which software testing is performed independently of the regular mode, and the simulation mode is a mode in which operator training is performed using a simulation program that simulates the input / output of a distant monitoring control device, for example. Is.

The first figure 10 and 11 is an output device for displaying the processed by giving and / or function processor input data to the function processor 1 ₁ to 1 ₃ data, CRT devices specifically Figure 2 Or a video projector. These input / output devices 10 and 11 are devices common to the A system and the B system, and are connected to either the A system or the B system computer system system.

In the system management device 9, one of the redundant 9 _X and 9 _Y is virtual operation mode management of each computer system system, management of each functional processor belonging to the computer system system, computer of each input / output device. The connection management to the system system and the management of the equipment data described above are performed, and the other is on standby. Further, this system management device 9 has a table 12 for configuration control, and in this table 12, as shown in FIG.
Correspondence between the component type of the functional processor and the code within the type and the computer system to which it belongs, and the input / output device 10,
The correspondence between 11 and the computer system to which it is connected is described. In this example, the computer system system is displayed as "main system" and "slave system".
The B system is a system that is operated in the normal mode, and the slave system is the other system other than the master system.

Each feature processor (1 _1X , 1 _1Y ), (1 _2X , 1 _2Y ), (1
_3X , _13Y ) and input / output devices 10 and 11 are an application execution unit 13 that performs processing according to a predetermined program, the above-mentioned configuration control table 12, and data exchange with other devices by referring to this table 12. It has a data exchange control unit 14 for controlling.

Next, the operation of the above embodiment will be described. In each component type of the functional processor, the symbol in the type is X, that is, the functional processors 1 _1X , 1 _2X , 1 _3X belong to the A system,
The symbols with a type of Y, that is, 1 _1Y , 1 _2Y , and _13Y belong to the B system, the A system and the B system are operating in the normal mode and the standby mode, respectively, and the input / output devices 10 and 11 are It is assumed that it is connected to the A system. If the input / output device 10 is a CRT device, for example, the data set and input from the screen and displayed is output from the application execution unit 13 of the CRT device to the corresponding functional processor. The output data at this time includes the component type ( ₁₁ ,
1 _2, 1 ₃ of the sensitive) are included, the in the CRT apparatus, the table 12 of the data exchange controller 14 the configuration control
With reference to, the internal symbol of the component type of the functional processor belonging to the computer system to which the CRT device is connected among the functional processors of the relevant component type is added to the output data as the destination. For example, if the output data from the application execution unit 13 to the function processor 1 ₁ as the destination, the data exchange controller 14, is output from the CRT device functions processor 1 _1X belonging to the main system as a destination.

On the other hand, in the functional processor _11X , for the data sent from the input / output device 10, its own application execution unit
The data exchange control unit 14 determines whether or not the data is to be taken into the device 13 by referring to the table 12. In this case, since the functional processor _11X belongs to the computer system system, that is, the master system, to which the input / output device 10 is connected, the functional processor _11X determines that the above data should be taken and receives it.
By doing so, it is possible to prevent data from the input / output device 10 from being erroneously given to the functional processor on the slave side.

Here, if the functional processor 1 _1X on the main system side fails,
The system management device 9 _X recognizes the failure and switches the affiliation of the computer system system of the relevant functional processor 1 _1X from the A system to the B system, that is, from the master system to the slave system, and also assigns the affiliation of the functional processor 11 _{Y in} the standby mode. The B system is switched to the A system, that is, the slave system is switched to the master system. This switching process rewrites the contents of the table in the system management device 9 _{X as} “subordinate” for 1 _1X and “master” for 11 _Y , and similarly for the table 12 in each device. And it is done by rewriting all at once. In addition, the above switching processing is performed by the system management device 9 _X via an operation panel (not shown).
It is also performed by giving a switching instruction to.

The present invention in above, each function processor 1 ₁ to 1 ₃ and triplicated, system determines the output data have not a preparative to two output values of which, or each of the functional processor 1 _1,
Can also be applied to the system such that only duplex configuration for one of the ~ 1 _3.

H. Effect of the Invention According to the present invention, the processing load is distributed to each functional processor divided for each function, and each performs processing in parallel, so that responsiveness is improved compared to a centralized system. You can In addition, when a function is added, a new functional processor to realize that function is prepared and added to the system that is already in operation. The degree of freedom of the system can be increased, and the influence on the function of the system in operation can be reduced. A table in which each device has so-called configuration control such as virtual operation mode management of each computer system system, management of each functional processor belonging to the computer system system, and connection management of input / output devices to the computer system system It is separated from the original application by executing it by a method such as simultaneous rewriting and data exchange control based on the reference result of the description contents, so the software is built even though it is a function distributed type. It has the effect of being easy.
