Abstract

PROBLEM TO BE SOLVED: To provide a message editing method where an error in accident message editing is eliminated. SOLUTION: A message editing program preserves a present measured value when the state change of an equipment is reported (S1) and executes message editing by using the measured value when the measured value is preversed at the time of a report concerning time-up and by fetching the present measured value unless the value is preserved (S3, S4, S5). Message editing and non-editing are held as a flag and message editing is executed only when message is not edited yet (S6, S7). A means for automatically executing message editing except when the message is edited at the time of the recovery of the equipment and a key state in relation to it is added.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supervisory control system for electric power equipment and the like, and a method of editing a message for notifying an operator of an accident occurrence status of equipment to be supervised or controlled, or a message for notifying a terminal in charge of the equipment. Regarding

[0002]

2. Description of the Related Art In supervisory control of electric power equipment, a message output process due to an accident takes in a state change (startup) of a device to be subject to supervisory control and a measurement value (telemeter) which changes with it as monitoring information, There are some which edit the accident message according to the combination of these monitoring information and output it.

A processing method for editing an accident message will be described with reference to FIG. The program A that detects a change in the state of the device generates a change in the state of the device (startup) and a change in the state of the key (change in the state of the upper device related to the lower device)
Of the occurrence of the state change, and when the device and the key are restored thereafter, the notice of the state change return is fetched. When the program A is notified of the state change, it notifies the message editing program B as the state change information a.

The program B sets the time period T _X of the acquisition waiting timer B1 of the measured value TM when the accident message is edited by combining the information a with the measured value related to the information a.

The time management program C for managing the timer B1 is executed, for example, in a cycle of 1 second, and when the timer B1 is set, the program B is notified of a message edit request b when the time limit is reached. .

When the message edit request b is notified, the program B confirms that the key state change necessary for the combination is changed, acquires the measured value TM, and outputs the accident message combined with the measured value. To edit. FIG.
The message edit timing is shown.

[0007]

In the supervisory control system for electric power equipment, the state change of the equipment related to the accident and the measurement value TM combined with the measurement value TM are restored within a fixed time (for example, 10 seconds) after the occurrence of the accident. System configuration.

Further, although the programs constituting this system are shown as three programs A, B and C in FIG.
It will be around 0. Between each of these heavy rain programs,
The processing priority is determined, and the message editing program B has a relatively low priority.

To edit an accident message that combines measured values, a large amount of equipment state changes are handled, and the state change detection program A and related programs perform processing. When an accidental state change combined with a measured value is included in these state change signals, the state change detection program A notifies the message editing program B of a notification a. However, since the program B has a low processing priority, it is immediately notified. Does not start the process, and sets the timer for acquiring the measured value only when the process can be started, and the message is edited when the message edit request b is notified at the time-up.

Therefore, as shown in FIG. 6, when the notification a from the program A is given, the timer is set, and when the notification b is received after the time-up T _X , the measured value TM
May already be restored (because TM changes the value at the site), and the measured value may be edited with an incorrect value when the accident message is combined with the measured value.

Further, as shown in FIG. 7, when the processing delay of the program B becomes long, a timer is set at the start of processing,
While the time management program C is counting the timer, the program B is notified that the device has returned, and the processing is performed.
When the message edit request b due to time-up is notified after that, the state change of the key is restored when the message is edited. Therefore, the program B judges that the state of the key has not changed, and an accident that combines the measured values Edit the message.

Further, when the accident message editing in which the measured values are combined is continuously generated, as shown in FIG.
The combination of the first and second state changes and the measured values may be incorrect and may be edited, such as the message being edited by combining the second state measured value with the first state change.

An object of the present invention is to provide a message editing system which eliminates an error in editing an accident message.

SUMMARY OF THE INVENTION The present invention is a state change detecting means for detecting a state change of a device to be monitored and controlled and a state change of a device related thereto as generation and restoration of a key, and a state change detecting means from this means. Message editing means for starting a related measurement value acquisition waiting timer when a notification of state change occurrence and return is received, and time management means for notifying the message editing means of the time up of the timer, the message editing In editing the accident message in which the means combines the device whose state has changed and the measured value, the message editing means stores the current measured value when receiving a notification of the state change of the device from the state change detecting means. If the measured value is saved when the time management means notifies the time-up, the measured value is used for saving. If not and performing takes in the message edit the current measured value.

When the message editing means receives the key return notification from the state change detecting means,
When the accident message has not been edited, the key state change occurrence data is held, and the data is reset after the accident message is edited.

Further, the message editing means edits the accident message only when the accident change message is returned from the state change detecting means and the accident message has not been edited.

[0017]

1 is a processing procedure of an accident message editing program B showing an embodiment of the present invention.

When the notification a of the state change of the device is received from the state change detection program A, conventionally, the measured value is acquired after the timer waiting for the acquisition of the measured value expires.
In addition, the current measurement value is acquired and saved as system data when the notification a of the state change of the device is received (S1). In addition, it is set as a flag of the system data that the editing of the accident message for importing the measured value is not edited.

After that, the timer for waiting for acquisition of measured value is set in the same manner as in the conventional case (S2).

Next, when the time-up notification b is notified from the time management program C, it is checked whether or not the measured value is stored in the system data (S3), and the measured value is stored as the system data. In that case, the measured value is taken in (S4), and if not saved, the current measured value is taken in (S5).

Then, it is checked from the flag of the system data whether or not the accident message combined with the measured value has been edited (S6), and if not edited, measurement is performed on condition that the state of the key saved as system data has changed. The accident message combined with the value is edited (S7). At the end of this editing, the flag is changed to edited. If the message has been edited, the message is not edited.

Therefore, according to the present embodiment, as shown in FIG. 6, even when the measurement value TM has already been restored when the notification b is received after the time-out T _{X of the} timer, the saving is performed at the notification a. Accident messages can be edited without error using the measured values.

FIG. 2 shows the processing of program B when a key return notification is received from state change detection program A. When this notification is received, it is checked whether the accident message has been edited by reading the flag (S11), and if it has been edited, the key state change data is reset (S1).
2) If the key state change has not been edited, the key state change data is not reset and the key state change data is held in the key state change occurrence state.

Therefore, according to the present embodiment, as shown in FIG. 7, the processing delay of the program B becomes long, and the state change of the key is restored before the message edit request b is notified due to the time-up of the timer. However, by preventing the system data from being reset, it is possible to prevent the program B from judging that there is no change in the state of the key and editing the accident message combining the measured values.

FIG. 3 shows the processing of the program B when the restoration notification of the device state change is received from the state change detection program A. When this notification is received, it is checked whether the accident message has been edited by reading the flag (S2
1) If it has not been edited, the accident message is edited and the key state change data is reset (S2).
2). If the message has been edited, the message is not edited even for notification of device restoration.

Therefore, according to this embodiment, when the device is restored before the message edit request is issued from the program C, message edit is automatically performed on the message which has not been edited. As shown in the figure, the message can be edited without invalid combination of the measured values even when the device status changes continuously. If the message has been edited, the message is not edited, but the message is edited when the edit request is made.

[0027]

As described above, according to the present invention, the message editing means saves the current measured value when it is notified of the change in the state of the device, and is notified of the time-up by the time management means. If the measured value is saved when you save it, the measured value is used, and if it is not saved, the current measured value is fetched and the message is edited. Even if there is an accident, you can edit the accident message without error using the saved measurement values.

Further, according to the present invention, when the accident message is not edited when the notification of the key return is received, the occurrence data of the key state change is held, so that the time up for the key return is delayed. You can edit the accident message without error.

Further, according to the present invention, since the accident message is edited only when the accident message is not edited when the restoration notification of the state change of the device is received, the accident is detected without error even when the continuous state change is detected. You can edit the message.
