Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supervisory control device and a supervisory alarm method used for supervising process automation, building management, water supply and sewerage fields, and the like. Accordingly, the present invention relates to a supervisory control device and a supervisory alarm method for the same, in which the weighting of alarms can be arbitrarily set.

[0002]

2. Description of the Related Art Conventionally, in a distributed type supervisory control device used in the fields of process automation, factory automation, building management, water supply and sewerage, etc., the input / output signals of these processes and the parameters related to the input / output signals thereof are used. -Although tags are managed by tags, monitoring of alarms such as sensor abnormalities, upper and lower limit abnormalities, change rate abnormalities, contact abnormal signals, etc., based on the contents of the tags, is carried out in the distributed supervisory controller.・
It is performed by an operator interface station for operation (hereinafter referred to as OIS).

By the way, this type of distributed supervisory control device is composed of various fields (uses), control targets, control devices, etc. When viewed from the whole of the device, each process control target, each control device The importance of the process alarm should be different depending on the situation, etc., but in the case of the conventional weighting of the process alarm by OIS (hereinafter referred to as the grade), Is determined based on the alarm type, for example, sensor abnormality of various sensors, upper / lower limit abnormality of various processes, etc., regardless of the tag type, and the tag and alarm type have a fixed relationship in advance. ing.

[0004]

Therefore, in the distributed monitoring and control apparatus as described above, when the same alarm type is a serious alarm depending on the part of the process, on the contrary, a minor alarm is generated. Or there is a case where it is not necessary to output the alarm. This means that as the target process becomes more diverse, large-scale, and complicated, it is necessary to set the alarm grade in detail. However, in the current monitoring and alerting method, an alarm obtained from a combination of different tag types and the same alarm type is used.
With regard to the grade of the system, it is set to the highest value uniformly while taking safety into consideration, so even if it is a slight alarm, it may be reported as a serious alarm depending on the tag. Therefore, it is necessary to examine the alarm contents by the operator every time it is issued.

Further, in the case of monitoring control of a special plant or process control target, there are cases where a predetermined alarm type is insufficient, but in this case, a new arbitrary special type is newly added. There is a problem that an alarm cannot be added, and in the end, the operator is notified by a method other than the alarm monitoring under the control of the tag. As another method, for example, a method in which the operator is notified by operator guidance is given as a typical example, but since it is out of tag management, the operator's burden becomes heavier. The present invention has been made in consideration of the above-mentioned circumstances, and can sufficiently cope with a large-scale and complicated control system.
It is an object of the present invention to provide a monitoring control device capable of finely setting the mode.

Another object of the present invention is to provide a special alarm.
It is an object of the present invention to provide a monitor / control device in which the grade can be easily set even in the game system, and the grade and the like of the alarm can be arbitrarily registered and changed as necessary. Still another object of the present invention is to provide a monitoring and alarm method capable of setting an arbitrary grade depending on the tag type even in the same alarm.

First, the first and second aspects are set forth.
The invention corresponding to (1) receives a transmission message including at least the tag management number and status information of the tag sent from the lower station, and the upper station side grades from the transmission message. And decide
In the supervisory control device which outputs a system, the upper station is a tag conversion table for converting the tag management number in the transmission message to the upper station tag registration number, and this tag. A tag information table storing a tag type corresponding to a registration number and an alarm grade number different for each tag type, status information of the tag in the transmission message, and a tag of the tag information table. An alarm type table for storing an alarm type determined based on the type, and an alarm grade determination information based on the alarm grade number corresponding to the alarm type and the tag registration number. And the information stored in each table in a predetermined order based on a transmission message from the lower station. A process alarm generation processing means for determining the rade, and a registration tool for registering and updating the information in each table by inputting / outputting data from the higher station. It is a configuration provided with.

Next, the invention according to claim 3 provides the alarm information such as the tag management number and the status information of the tag from the lower station side with respect to the abnormality or the failure on the lower station side. The transmission message including the transmitted transmission message is transmitted, and the upper station side specifies the tag type having a correspondence relationship with the tag management number of the transmission message in advance, and the tag type and the transmission message described above. This is a method of determining the alarm grade from the alarm type converted from the status information of the tag.

[0009]

Therefore, according to the present invention, by taking the above-mentioned means, the process alarm creation processing task can be performed based on the transmission message from the PCS which is the lower station when the process is abnormal. Of the respective tables, the tag conversion table is first called to obtain the management tag registration number in the OIS which is the higher station for the tag relating to the process abnormality.

Thereafter, the alarm type table is based on the bit number of the changed status obtained from the transmission message and the tag type held in the tag information table corresponding to the tag registration number. The alarm type is obtained by calling the line. Based on this alarm type and the alarm grade pattern number registered in the tag information table and different for each tag registration number, the alarm grade −
Since the grade of the alarm to be issued by calling the bull is determined, the grade of the alarm can be appropriately obtained by combining each tag with each number and type.

As a result, by properly setting the information in each table, the grade of the alarm can be finely determined and the alarm can be output, and a dedicated registration tool is provided. As a result, the table information can be easily set and changed not only by an optional special alarm but also by a normal alarm.

Furthermore, in another invention, an alarm grain
By determining the mode by converting the information related to individual tags in the transmission message, it is possible to set an arbitrary grade depending on the tag type even with the same alarm.

The task 3a of the OIS3 receives the transmission message from the PCS2 as shown in step ST1. At this time, the task 3a periodically judges whether or not the transmission message is received (ST).
2) If it is judged that there is a message, it is judged whether or not it is a process alarm message (ST3).

If the message is other than the process alarm, the message receiving task 3a does not perform any processing.
Another task corresponding to the contents of the transmission message will process (ST4). When it is determined that the message is a process alarm message, a mail for creating a process alarm process is created as shown in ST5, and then the process alarm is created via the process alarm creating mail box 3b.
It is passed to the task creation processing task 3c.

Here, in the process alarm processing creation mail, at least the PCS number in the transmission message from the PCS 2, the tag management number in the PCS, the status before the alarm detection and the status at the time of detection, The process value at the time of detection is included.

Next, FIGS. 4 and 5 are flowcharts for explaining the operation of the process alarm creation processing task 3c for creating a process alarm. This task 3c is
A process alarm creating mail is received from the message receiving processing task 3a via the process alarm creating mail box 3b (ST11), but after the reception of the mail is detected at this time (ST12), FIG.

Then, after confirming the conversion of the tag registration number (ST14), the status's Bit number changed based on the status before the alarm detection, which is one of the information in the received mail, and the status at the time of detection. (ST1
5). Here, if there is a change in status as shown in step ST16, an alarm as shown in FIG. 7 is generated based on the Bit number and the tag type in the tag information table 3e corresponding to the tag registration number. The type table 3f is called to obtain the alarm type (ST17). The alarm type table 3f is provided with, for example, a tag type on the vertical axis and a status bit number on the horizontal axis.
The registered alarm type is obtained from the combination of task bit numbers, that is, the intersection of the vertical axis and the horizontal axis. Therefore, after determining whether the alarm type is registered (ST18), if the alarm type is registered, the alarm grade pattern varies depending on the tag registered in the tag information table 3e. Based on the alarm number and the alarm type (alarm message), the alarm grade table 3g shown in FIG. 8 is called to determine the grade of the alarm (ST19). Then the gray of the alarm
In some cases, the status changes after confirming the registration of the grade in the alarm grade table 3g in the next step ST20. It is determined whether there is any (ST21). As a result of this determination, whether the alarm is generated (ST22) or recovered (ST23), the state of the alarm is stored in the process alarm state information file 3i (ST24), and , Used to create a representative of alarms when multiple alarms appear in the same tag (ST
25).

After that, an alarm is issued and a mail for recording is created (ST26), and the created mail is used as the process alarm mail box 3j and the process alarm.
Alarm notification via the mail recording mailbox 3k,
It is transmitted to the recording processing task 3n.

The notification / recording processing task 3n uses the mail for recording and recording of the alarm from the mail box 3k to notify the CRT display device 5 and the like and to the hard disk device 4 and the like. Record. Although not described because it is not related to the grade determination procedure, the PCS sent to the process alarm creation processing task 3c.
Of the transmission messages from 2, the information indicating the process value at the time of detection is similarly issued and recorded.

(A) Tag No. The alarm of 168 is that the upper and lower limits are abnormal and the grade is a heavy alarm. (B) Tag N
o. The alarm of 171 can read that the upper and lower limits are abnormal and the grade is a medium alarm. In addition, the alarm grade displayed here is used to arbitrarily register the contents of each table by the registration tool 3h when determining the grade.
By changing, it can be set appropriately according to the tag.

A comment "occurrence" appears on the right side of the grade displayed on the screen. This is the comment "occurrence" when it is judged that an alarm has occurred in ST21. It was done.

Therefore, according to the configuration of the above embodiment, in the process of determining the importance of the alarm to be issued, the process alarm creation processing task 3c, the tag conversion table 3d, and the tag 3d By providing the information table 3e, the alarm type table 3f, and the alarm grade table 3g, the tag type, status bit number, alarm grade pattern number, The grade of the alarm can be finely determined by using a combination of several elements such as the type of the alarm. That is, since the alarm to be issued for each tag is individually determined, the operator may carry out the alarm processing as it is without examining the contents of the alarm issued on the screen. Therefore, it is possible to take a quick response to the process alarm and perform detailed alarm monitoring.

Since the information in each table for determining the grade of the alarm can be appropriately registered and updated by using the dedicated registration tool 6e, any special alarm can be set. Moreover, even a normal alarm can be easily corrected when necessary. In addition, the present invention can be modified in various ways without departing from the scope of the invention.
