Abstract

<P>PROBLEM TO BE SOLVED: To provide a plant monitoring device for efficiently notifying a warning to which an operator should respond out of many of generated warnings by preferentially and selectively displaying the warning to which countermeasure operation is not conducted yet. <P>SOLUTION: A process value is input from a process input device 2. When the input process value is in a warning state, a process input processing part 4 generates warning message data 8. A warning message display processing part 9 displays the warning message on a display device 3 on the basis of the generated warning message data 8. The operator conducts the countermeasure operation on the basis of this. In regards to the warning to which the countermeasure operation has been already conducted, the operator operates an operation button to inform to a countermeasure operation implementation notification processing part 10 that the countermeasure operation has been already conducted. A countermeasure operation implementation flag 11 is turned to indicate that the countermeasure operation has been conducted from the countermeasure operation implementation notification processing part 10 to reflect the countermeasure operation implementation flag 11 on a display of the warning message. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a plant monitoring apparatus that outputs an alarm state of a plant as an alarm message.

  The conventional plant monitoring device compares the measured value with a preset alarm value to determine whether an alarm condition has occurred in the plant, and outputs an alarm message in the alarm range to respond to the operator. In recent years, the number of alarm points to be monitored has become enormous, and if a large number of alarms are generated at once, the operator's response operation is delayed, and in the worst case, the equipment is damaged. It has come to interfere with plant operation. For this reason, individual alarm factors are classified in advance for each plant facility / system, the importance is set, and a means for notifying the operator of alarm messages according to the importance is provided. It can be implemented. (See Patent Document 1)

  The operator performs a corresponding operation on the output alarm message. As a result, if the process amount falls within the alarm limit, the alarm is returned and the corresponding information is deleted from the alarm state table and the alarm message data.

JP 2001-117630 A (pages 8 to 10, FIG. 1)

In the conventional plant monitoring apparatus, although display according to importance is performed, there are the following problems.
Operators perform response operations from alarms with a high level of importance.However, if a large number of alarms occur, there may be several tens of pages even with only an alarm due to restrictions on the screen area of the display device. Although it was implemented, there was a problem that it was displayed together because the alarm was not restored.
Also, depending on the alarm factor, the corresponding operation may be the same, but since the output of the alarm message is based on the system and importance, multiple alarms of the same corresponding operation will be output. Thus, it is possible for the operator to perform a faster response operation.

  The present invention has been made to solve the above-described problems, and can display alarms that have occurred in large numbers by enabling priority and selective display of alarms that have not yet been handled. The object is to obtain a plant monitoring device that can efficiently notify an alarm to be handled by an operator.

  In the plant monitoring apparatus according to the present invention, a process value from a plant input point is input, and a process input processing unit that generates alarm message data in accordance with the input process value, generated by the process input processing unit. Alarm message display processing unit that performs alarm message display processing based on the alarm message data, the corresponding operation execution flag that stores the execution state of the corresponding operation for the alarm message, and the alarm message displayed by the alarm message display processing unit The corresponding operation execution notification processing unit that receives the notification of the corresponding operation execution and sets the corresponding operation execution flag in advance, and the alarm message display processing unit reflects the state of the corresponding operation execution flag in the display of the alarm message It is.

  As described above, according to the present invention, a process value from a plant input point is input, and a process input processing unit that generates alarm message data according to the input process value is generated by the process input processing unit. Alarm message display processing unit that performs alarm message display processing based on the alarm message data, the corresponding operation execution flag that stores the execution state of the corresponding operation for the alarm message, and the alarm message displayed by the alarm message display processing unit The corresponding operation execution notification processing unit that receives the notification of the corresponding operation execution and sets the corresponding operation execution flag in advance, and the warning message display processing unit reflects the state of the corresponding operation execution flag in the display of the warning message. This makes it possible to identify alarm messages that require action. Corresponding operation delay is eliminated.

Embodiment 1 FIG.

The process input processing unit 4 inputs a process value from the plant via the process input device 2, converts the engineering value by the engineering value range stored in the input point information table 5, and has an alarm presence / absence. Is compared with the alarm limit value of the alarm limit table 6, and if the converted process value deviates from the alarm limit value as a result of this comparison, the point number stored in the input point information table 5; Alarm message data 8 including an input point name, an alarm limit value, and a current value is created, and an alarm state table 7 corresponding to the input point is set to alarming.
The alarm message display processing unit 9 displays an alarm message on the display device 3. The operator performs an operation corresponding to the alarm, and as a result, if the process value falls within the alarm limit, the alarm is restored, and the corresponding information is deleted from the alarm state table 7 and the alarm message data 8.
When an operator performs a corresponding operation for an alarm, the operator presses the operation button 30 added to the alarm message displayed on the display device 3 to receive the information via the corresponding operation execution notification processing unit 10. And the corresponding operation execution flag 11 is set to 1 based on this information. The warning message display processing unit 9 refers to the corresponding operation execution flag 11 and displays whether or not the corresponding operation has been performed by changing the button color of the alarm message screen.

  According to the first embodiment, it becomes possible to identify the most important alarm that needs to be handled at that time from the alarm message of the display device 3 that changes every moment due to the change in the situation of the plant. The response operation delay is eliminated, and stable plant monitoring operation is possible.
