A communication mode in which information is written to and read from the operation support system 1 in accordance with the telecon transmission procedure and a predetermined information area is assigned and managed in the same manner as the telecon monitoring control. Is called a virtual channel.

Next, the operation of the operation support system 1 having the above configuration will be described.
(Operation procedure data registration process)
Operation procedure data is transmitted to the operation support system 1 from any one of the host computers 81 to 83. This data is received and processed by the telecon communication processing means 25, extracted via the virtual channel data converting means 24, and stored in the operation procedure data file 31 by the operation procedure input means 21.

  FIG. 9 shows a data configuration example of the operation procedure data file 31 in the present embodiment. The scheduled operation time, the scheduled operation system, the operation device, the operation (or the work contents of the worker), the operation status, and the comment can be stored. It should be noted that information of the jurisdiction computer (or work department) may be storable although it partially overlaps with the data in the control right area allocation table.

  The contents of the file 31 are sent to each of the upper level computers 81 to 83 periodically or whenever an additional change is made. Specifically, according to the telecon transmission procedure, the operation procedure input means 21 passes the data of the file 31 to the virtual channel conversion means 24 when a fixed period or state change occurs. The virtual channel conversion unit 24 converts this into a telecon format and passes it to the telecon communication processing unit 25. The telecon communication processing means 25 determines, by the control object determination means 27, a computer that currently has a control right or may have a control right for the operation target device of the operation procedure data. To send. Note that the data of the file 31 may be transmitted to a predetermined higher-level computer without performing the determination of the control target determination unit 27. The host computer saves and updates the received data in the operation procedure data file 31 '.

(Misidentification prevention data registration process)
On the other hand, the misidentification prevention data is also sent from the higher level computers 81 to 83 to the operation support system 1, and the misidentification prevention data is transmitted via the telecon communication processing means 25, the virtual channel data conversion means 24, and the misidentification prevention treatment registration means 22. Saved in file 32. The data example of the file 32 is the same as that of FIG.

  Similarly to the operation procedure data, this misidentification prevention processing data is transmitted to the upper computers 81 to 83 in accordance with the telecon transmission procedure, and stored and updated in the misidentification prevention data file 32 '.

(Control right processing)
Next, the control right function of the operation support system 1 will be described. A control right assigns a high-order computer (or jurisdiction area) that can control each device or group of devices, and which computer currently has the control right by a control right switch (hereinafter referred to as a control right SW). This is a function to send only the control command of the computer having the control right to the operation target device.

  First, the control area allocation table 42 is registered in advance. The table 42 includes a device registration table 42a and a control source computer allocation table 42b.

  FIG. 10A shows a data configuration example of the device registration table 42a. In the device registration table 42a, the type of control right switch (SW) is stored for each operation target device, and a control source computer is assigned to each control right SW.

  FIG. 10B shows a control source computer allocation table 42b. A plurality of computers are associated with each type of control right SW.

  FIG. 11 shows a data example of the control right SW table 41. This table is associated with the control source computer allocation table 42b, and a flag is set for a computer that currently has a control right for each type of control right SW, that is, can issue a control command to the operation target device. Yes. The control right switching request can also be transmitted from the host computer. However, in the operation support system 1, if the host computer performs a failure diagnosis by an ack / nack check or the like and determines that there is a failure, the control right SW table 41. To the next highest priority computer. The change at this time is notified by the telecon state change function using the virtual channel.

(Operation execution processing)
Under the above-described control right function, a control command is output from the host computer having the control right to the operation target device based on the operation procedure data 31 ′.

  Taking FIG. 9 as an example, among the operation procedure data, those for which the own computer has a control right based on the device registration table 42a are identified and displayed, and the control to the operation target device is executed sequentially. Go.

  For example, if the sales office has the control right for 10CB in the first line in FIG. 9, the operation for 10CB is identified and displayed on the operation procedure data of the sales office by color change or the like. A cut command is output to 10CB. This control command is sent from the computer 83 at the sales office to the operation support system 1 and checked by the control target determination means 27.

  The control target determination means 27 extracts the 10 CB control right SW type from the device registration table 42a, and then uses the control right SW table to determine the computer having the control right from the flag position set for this type (this If it is confirmed that the control command is from the sales office), this control command is transmitted to the telecon slave station that operates 10CB. In addition, the status of the operation procedure data file 31 is changed to “end”. This change is transmitted as a state change to each computer via the virtual channel conversion means 24 and the telecon communication processing means 25.

(System diagram display processing)
Each of the higher-level computers 81 to 83 has a system diagram display means 23 and a system diagram DB 33, and the system 23 displays the system diagram on the display unit 12 at its own place. At this time, with reference to the operation procedure data file 31 ′, for the device scheduled to be operated, the misidentification prevention content is further extracted from the misidentification prevention data file 32 ′ and displayed on or near the symbol of the device. To do.

  The comment data in FIG. 9 is displayed based on the movement operation of the operator's cursor. For example, when the operator moves the cursor over a symbol of a certain device, the system diagram display means 23 searches the operation procedure data file 31 ′, and the device is present in the file 31 ′, and at that time When the time and the scheduled time are within a predetermined period, the comment of the device is displayed in a balloon near the symbol. For example, if a system 1 device is displayed on the control center side and the operator moves the cursor over the symbol of the device, if the status at that time is not completed, “XX: XX scheduled to be withdrawn” Is displayed.

  For the status of the operation procedure data shown in FIG. 9, the local worker connects to the communication network 5 from the mobile terminal 70, communicates with the operation support system 1, and rewrites the status of the operation procedure data file 31. For example, when the 1CB drawer operation is completed, the status is changed from “not yet” to “finished”.

(Control right takeover processing)
For example, when the operation of entering the CB of the system 4 is not performed even after the scheduled time, an abnormality notification is sent to all the computers that can own the control right for the CB through the virtual channel. As a result, even when a computer having the control right goes down due to a failure or the like, another computer outputs a control right SW switching request using the virtual channel, and the control right is switched. A series of control is continued by entering the CB and outputting a command.

  As described above, according to the present embodiment, instructions from a computer such as a control office or sales office to the operation target device are relayed through the operation support system, and the operation procedure data, work plan data, and misrecognition are performed on the operation target system side. By holding preventive action data, it is possible to thoroughly prevent false positives between departments. In addition, referring to the operation procedure data when the operation target device is specified, if there is a work plan for the specified device, the scheduled time and the details of the work are displayed as comments. Whether or not control output is possible can be determined reliably and easily.

  Furthermore, since the control right is switched by the virtual channel by the control right SW, the computer side can easily take over the control by the standard telecon communication function, perform reliable work, and erroneous control output. Can prevent

  The present invention can be applied not only to the electric power field but also to various fields in which plant monitoring control is performed.
