DETAILED DESCRIPTION OF THE INVENTION A. Industrial Field of Application The present invention relates to a configuration control processing method for a functionally distributed system applied to centralized monitoring and control of an electric power system, for example. In systems that execute tasks such as centralized monitoring and control using
These functional processors, input/output devices, and system management devices are connected via a local area network to manage the operation mode of each virtual computer system, manage the affiliation of each functional processor to the computer system, and manage the computer of each input/output device. Connection management to the system system is performed by writing in the configuration control table provided for each device, and by making it independent from the original business, it improves responsiveness and function extensibility, and enables functionally distributed Despite this, we made the system easy to assemble.

C8 Conventional technology As power systems become larger and more complex, there is a need for more sophisticated systems to automatically aggregate and record information on substations, etc. within the power system and centrally monitor and control them. ing.

Conventionally, in most cases, such systems are divided into two computer system systems, one computer is assigned to each system, and one of the systems performs the actual online operations such as monitoring, control, and recording. However, a system was adopted in which the other system was put on standby, resulting in a centralized system in which all online business processing was executed by a single computer.

00 Problems to be solved by the invention The above-mentioned centralized system centralizes all online business processing on one computer when multiple state changes occur in a short period of time, such as when a power grid accident occurs. As a result, the processing load on the computer increases rapidly and the responsiveness of the system decreases. In addition, when planning a system, we select a computer model taking into account the functions that are planned to be added in the future. However, if it becomes necessary to add an unplanned function after the system is operational, we will consider the processing capacity of the computer that is currently in operation. Due to the limited memory size, etc., there are restrictions on functional expandability. Furthermore, when changing functions, the software must be changed significantly, which makes it difficult to handle, and this also has the disadvantage that the degree of freedom of the system is small.

An object of the present invention is to provide a functionally distributed system that can improve responsiveness, improve functional expandability, and increase the degree of freedom of the system.

93 Means for Solving the Problems The present invention includes a plurality of functional processors, each of which has an application execution unit, and each of which performs assigned processing in parallel, and each of which has an application execution unit,
A system configuration in which a plurality of input/output devices that provide input data to the functional processor and/or output and display data processed by the functional processor, and a system management device that performs configuration control management regarding the system configuration are connected via a local area network. each of the plurality of functional processors belongs to one of the virtual systems to configure a plurality of computer system systems, and the system management device has an operation mode of each virtual computer system. A configuration control table is provided that describes the status, the correspondence between each functional processor and the computer system to which it belongs, and the correspondence between each input/output device and the computer system to which it is connected. The processor and each input/output device are provided with a configuration control table into which configuration control information created by the system management device is written, and a data exchange control section.

21 Effect The system management device determines, at the configuration control state determination timing, the mode to which each computer system system should be operated, the computer system system to which each functional processor should belong, and the computer system system to which each input/output device should be connected. The judgment results are written to all the tables at the same time, 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 input/output device, and data exchange between each device. The control unit determines the destination of the data output from the application execution unit by referring to the configuration control table of the device, and also determines the destination of the data output from the application execution unit by referring to the table for externally input data. Determine whether or not to incorporate it into the application execution unit within the device.

G. Embodiment FIG. 2 is a block diagram of the entire system showing an example in which the present invention is applied to a power centralized monitoring and control system. First, the functions of each device in the figure will be briefly explained.

It will be done.

and a large screen display to notify the operator.

6 is a system monitoring board device that displays the operating status of the power system in a macroscopic manner on a system monitoring board; 7. 7n are CRT devices for displaying monitoring results and inputting setting values, and 81 to 8n are printers for printing various forms and records.

9 (9x, 9y) is a redundant system management device, which collectively manages equipment data required to realize the functions of each device, and issues commands to switch operation modes to each device as described later. , and sends out affiliation/connection switching authority commands.

In this embodiment, the functional processors and other devices described above are connected through a local area network, and the main parts of the configuration are conceptually shown in FIG. 1. In this system, the various processing tasks that were performed by computers in the conventional two-line system are divided into functions, and for example, three sets of functional processors 1. A method is adopted in which the functional processors 11 to 13 of each set execute independent processing in parallel.
3 are each duplicated and consist of functional processors numbered with suffixes X and Y, respectively. Here, the codes 11 to I3 are codes corresponding to the assigned component types, and the codes x and Y correspond to codes within the component types. And a virtual two-line computer system A
Considering a system and a system B, one of the duplicated functional processors belongs to system A and the other belongs to system B. One of these computer systems A and B operates in a regular mode, and the other operates in a non-regular operation mode, such as a standby mode, test mode, or simulation mode. Here, regular mode is a mode for executing all online operations such as monitoring, control, and recording, and standby mode is a mode in which the system is on standby so that it can switch to regular mode at any time in case of a failure in the regular mode system. The test mode is a mode in which software tests are performed independently of the regular mode.
The simulation mode is, for example, a mode in which operator training is performed using a simulation program that simulates the input and output of a remote monitoring and control device.

In FIG. 1, 10111 is an input/output device that provides input data to the functional processors 1 to 13 and/or displays data processed by the functional processors, specifically, the CRT device or video projector shown in FIG. etc. These input/output devices 10111 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.

The system management device 9 manages the operation mode of each virtual computer system, manages the affiliation of each functional processor to the computer system, and manages the computer system of each input/output device. The other side is on standby, managing the connection to and managing the equipment data mentioned above. This system management device 9 also has a table 12 for configuration control, and as shown in FIG. , and the correspondence between the input/output device 10.1 and the computer system to which it is connected. In this example, computer system systems are displayed as "main system" and "slave system." Of these, the main system is the system that is operating in the regular mode among systems A and B, and the slave system is the system that is operating in the regular mode among systems A and B. It is the other system other than the system.

Each functional processor (1, x, 1 +y), (lzx
-1ffiY), (13X, 1 ay) and the input/output device 1O1ll include the application execution unit 13 that performs processing according to a predetermined program, and the above-mentioned configuration control table! 2, and a data exchange control unit 14 that refers to this table 12 and controls data exchange with other devices.

Next, the operation of the above embodiment will be explained. Now, in each component type of the functional processor, the symbol in the type is X, that is, the functional processor 11Xs l lX5lsx is A
Those belonging to the system and whose type symbol is Y, that is, I Iv,
l tYq belongs to the 15th4B series, A series,
The B system is operated in regular mode and standby mode, respectively.
Assume that the input/output device 1O111 is connected to the A system.

For example, if the input/output device 10 is a CRT device, the data input and displayed on the screen is
It is output from the application execution unit 13 of the T device to the corresponding functional processor. The output data at this time is
The component type (1,, l
2,! , etc.), and in the CRT device, the data exchange control unit 14 refers to the configuration control table 12 and determines which of the functional processors of the corresponding component type is connected to the CRT device. The component type symbol of the functional processor belonging to the computer system system is added to the output data as the transmission destination. For example, the output data from the application execution unit 13 is a functional processor! 1 as the destination, data exchange control unit 1
4, the data is output from the CRT device with the functional processor IIX belonging to the main system as the destination.

- In the universal processor llx, the data exchange control unit 14 determines whether or not to incorporate the data sent from the input/output device IO into its own application execution unit 13.
is determined by referring to table 12. In this case, the functional processor 11X belongs to the computer system system, ie, the main system, to which the input/output device 10 is connected. Therefore, we judge that the above data should be included and accept the decision. By doing so, data from the input/output device 10 is prevented from being erroneously given to the functional processor on the slave side.

If the main function processor IIX fails,
The system management device 9X recognizes the failure and switches the computer system system of the functional processor IIX from the A system to the B system, that is, from the main system to the slave system, and changes the functional processor tty in standby mode to the B system. Switch from the system to the A system, that is, from the slave system to the main system. This switching process rewrites the contents of the table in the system management device 9 as "slave system" for IIX and "master system" for 1+y, and similarly and simultaneously for the table 12 in each device. This is done by rewriting. The above switching process is also performed by giving a switching instruction to the system management device 9x through an operation panel (not shown).

In the above description, the present invention includes each functional processor I.

~l, and a system in which output data is determined based on the output value of two of them, or a system in which only one of the functional processors 11 to l has a duplication configuration, etc. It can also be applied to

H0 Effects of the Invention According to the present invention, the processing load is distributed to each functional processor divided by function, and each performs processing in parallel, so responsiveness can be improved compared to a centralized system. can. Moreover, when a function is added, a new function processor is prepared to implement that function, and this is added to the system that is already in operation, which improves function expandability compared to a centralized system. The degree of freedom of the system can be increased, and the influence on the functioning of the system during operation can be reduced. A table is provided for each device to perform so-called configuration control, such as virtual operation mode management of each computer system, affiliation management of each functional processor to the computer system, and connection management of input/output devices to the computer system. By performing simultaneous rewriting and referencing the written contents using methods such as data exchange control, the software is separated from the original application, so it is easy to assemble the software even though the functions are distributed. It has the effect of being easy.
