BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. In each of the following embodiments, due to space limitations, the process computer 4 does not show all the processing means, and an alarm monitoring processing unit or a performance calculation unit related to the invention is extracted and illustrated. Further, in each drawing, the same parts as those in FIG.

(First Embodiment) A first embodiment of the present invention will be described below with reference to FIGS. 1 to 5. First,
In FIG. 1, process data such as the temperature, flow rate or valve open / close state of the plant 1 is taken into the process input processing unit 5 from the process input / output device 2 or the control device 3 and is set in a state suitable for subsequent processing and alarm monitoring is performed. It is transmitted to the alarm determination unit 6-1 of the processing unit 6.

The alarm determination unit 6-1 compares the process data fetched from the process input processing unit 5 with the limit value read from the limit value database 6-2 to see if the process data is in an alarm state. Determine whether or not
When the acquired process data changes from "normal state" to "alarm state" or when "alarm state" returns to "normal state", "current value and limit value of process data", "alarm state" , "Input point number" and the like to send to the alarm processing unit 6-3.

The alarm processing unit 6-3 reads the items from the "current value of process data" to the "input point number" from the alarm determining unit 6-1 while the "input point name" and "unit" are read. And are read from the input / output point database 8.

Further, the alarm processing unit 6-3 searches the message format database 6-4 to create text-based alarm message data according to the alarm message format defined by the message format database 6-4. The output processing unit 9 and the voice tuning unit 12-2 of the voice creating unit 12
Output to.

The output processing section 9 outputs the received warning message data to the display device 10 and the printer 11 to display and print. On the other hand, the voice tuning unit 12-2, which has received the alarm message data from the alarm processing unit 6-3, makes settings for adding a chime sound, changing the volume and timbre, etc., according to the state of the plant and monitoring. The information is output to the synthesized voice creating unit 12-1 together with the warning message data.

The synthetic voice creating unit 12-1 reads the alarm message data which is text data, converts the Chinese characters and alphabets into reading kana to create voice data, and outputs the voice data via the voice output processing unit 13. The alarm message is sent to the speaker 14 and a voice warning message is sent from the speaker 14.

Next, the processing by the alarm processing unit 6-3 will be described with reference to FIGS. 2 shows a configuration example of the message format table 6-4, and FIG. 3 shows a configuration example of the input / output point database 8. As shown in FIG. 2, the alarm message differs from that at the time of alarm generation or at the time of normal recovery, and the format for the display device specifies not only the display items but also the display color.

For example, in the case of "analog input alarm occurrence", it is composed of "input point number", "name", "current value", "inequality sign </>", "limit value" and "unit", and "analog" In the case of “return to normal input”, it is composed of alarm states such as “input point number”, “name”, “current value”, “unit”, and “return to normal”. For example, when "Analog input A101" in FIG. 3 is in the alarm state, the alarm message format at that time is "input point number", "name", "current value", "inequality sign", as shown in FIG. "Limit value"
And "units". And of these, "name"
And the "unit" (turbine speed / rpm) is read from the input / output point database 8 by using the "input point number" as a key, and the input point number (A101), current value (3650),
The limit value (3600) and the inequality sign (>) are read from the alarm determination unit 6-1.

The inequality sign (>) is the result of comparing the "current value" with the "lower limit value" and the "upper limit value" in the alarm determination unit 6-1. In this case, the current value (3650)> the upper limit value. Since it is a value (3600), the inequality sign is “>”.

The alarm processing unit 6-3 combines the items thus read in accordance with the alarm message format to create alarm message data. In the case of the example of FIG. 4, “A101 turbine speed 3650
> 3600 rpm ”.

Next, an example of tuning setting in the voice tuning unit 12-2 will be described. The voice tuning unit 12-2 adds, for example, a chime sound “Pawn” to the beginning of the voice data when the plant 1 is activated, “Ping Pawn” during normal operation, and “Beep” when stopped. It is to add each chime sound.

Regarding the alarm state, a male voice is used when the process data changes from the "normal state" to the "alarm state", and a female voice is output if the "alarm state" is "when returning to the normal state". Set the voice, etc.

Next, the processing of the synthetic speech creating unit 12-1 will be described with reference to FIG. FIG. 5 shows the process from the reading of the alarm message data to the conversion into voice data in the synthesized voice creating unit 12-1. In the synthesized voice creating unit 12-1, the read warning message data (A101 turbine speed 3650> 3600 rpm) is converted into a reading kana (HZ Zeroichi Turbine Kaitensu Sanzenroppyakugoju Dynari Sanzenroppyaku ARPM). The voice data is created according to the setting of the voice tuning unit 12-2.

As described above, in the present embodiment, when the process data of the plant 1 is in the alarm state,
Since the alarm message can be reported by voice through the speaker 14 in the main control room, the operator does not have to go to the screen of the display device 10 or the print contents of the printer 11 each time an alarm is issued, so that the alarm contents can be reported. It becomes possible to grasp.

Further, since all the operators who are in a range where the voice from the speaker 14 can be heard can receive the same information at the same time, it is possible to standardize the recognition level for the plant alarm.

(Modification) Next, a so-called modification in which the configuration of the first embodiment described above is slightly modified is shown in FIG.
It will be described with reference to FIGS. In FIG. 6, the alarm monitoring processing unit 6-A has a configuration in which a voice message database 6-5 for setting an alarm message format dedicated to voice notification is added to the alarm monitoring processing unit 6 of FIG. The voice message database 6-5 has a voice message dedicated alarm message format as shown in FIG.

By the way, when the alarm processing unit 6-3 receives the judgment result of the "alarm state" from the alarm judging unit 6-1, the alarm message format corresponding to the contents of the alarm is set in the voice message database 6-5. It functions to read a message, create a message dedicated to voice notification, and output it to the synthesized voice creating unit 12-1.

As a result, a message different from the warning message output from the display device 10 or the printer 11 can be notified by voice from the synthesized voice generator 12-1. FIG. 8 shows an alarm message dedicated to voice notification when an alarm is generated in A101, for example, and this message is composed of “input point number”, “name”, and “alarm state notification”. (Turbine speed) is read from the input / output point database 8 using the input point number as a key, the input point number (A101) is read from the alarm determination unit 6-1, and the alarm status notification (the upper limit has been exceeded) is an alarm. It is read from the voice message database 6-5 together with the message format.

The alarm status notification "The upper limit has been exceeded" is
From the inequality sign determined by the alarm determination unit 6-1, it is determined whether the deviation is the upper limit or the lower limit. In the alarm processing unit 6-3, the items thus read are combined according to the audio-only alarm message format, an alarm message is created, and an audio notification is given.

In this example, "A101 turbine speed
The upper limit has been exceeded. " As a result, the voice notification message when an abnormality occurs can be made a warning message that is easier for the operator to understand.

(Second Embodiment) A second embodiment will be described with reference to FIGS. In the second embodiment, a part of the alarm monitoring processing unit 6 according to the first embodiment is modified to be an alarm monitoring processing unit 6B.

In the alarm monitoring processing unit 6-B, the alarm determination unit 6-1 reads the process data fetched from the process input processing unit 5 from the limit value database 6-2, as in the first embodiment. By comparing with the limit value, it is determined whether the process data is in the alarm state, and when the process data changes from the normal state to the alarm state or returns from the alarm state to the normal state, the "current value" of the process data , "Limit value", "alarm state" and "input point number" are transmitted to the alarm processing unit 6-3 and a newly provided alarm level determination unit 6-6.

The alarm processing unit 6-3 outputs an alarm message to the display device 10 and the printer 11 when an alarm is generated, which is the same as in the case of the first embodiment. The difference is that the output processing of is not performed.

The alarm level determination unit 6-6 reads the alarm level of the process data in the alarm state from the newly provided alarm level database 6-7, and determines whether the alarm level of the generated alarm state is important. To determine. As for the item determined by the alarm level determination unit 6-6 that the alarm level is important, data regarding the alarm is output to the newly provided alarm processing unit (for voice) 6-3 ′.

This alarm processing unit (for voice) 6-3 'is similar to the alarm processing unit 6-3 in the first embodiment,
Regarding the alarm item, “name” and “unit” are read from the input / output point database 8, and the “input point number”, “current value”, “limit value” and “alarm state” of the process data are the alarms. The warning message is read from the level determination unit 6-6, an alarm message is created according to the alarm message format of the message format table 6-4, and the alarm message is output to the synthesized voice creating unit 12-1.

In this way, the alarm level determination unit 6-6
Alarm message data is created only in the alarm items that are determined to be important by the alarm processing unit (for voice) 6-3 ', and the synthetic voice creating unit 12-receives this alarm message data.
A voice warning message is created in step 1, and this voice warning message is sent to the speaker 1 via the voice output processing unit 13.
Reported from 4.

Next, the processing of the alarm level determination unit 6-6 will be described in detail with reference to FIGS. FIG. 10 shows an example of the configuration of the alarm level database 6-7. For example, in the alarm level database 6-7, FIG.
As shown in, for example, 2 depending on the importance of the alarm for each item.
The "alarm level 2" is defined as "important" and the "alarm level 1" is defined as "general".

FIG. 11 is a flow chart for explaining a case where the level 2 alarm is issued. The alarm determination unit 6-1 is A10.
When it is determined that the alarm is generated in 1, the process data “current value”, “limit value”, “alarm state”, and “input point number” are output.

The alarm level judging unit 6-6 receives the output signal from the alarm judging unit 6-1 and refers to the alarm level database 6-7 for the alarm level of A101, whereby the alarm level is 2: important. Make sure that. In this case, the alarm level determination unit 6-6 outputs A101 as an alarm item to the alarm processing unit (for voice) 6-3 '.

In response to this, the alarm processing unit (for voice) 6-
At 3 ', an alarm message of A101 (A101 turbine speed 3650> 3600 rpm) is created, and an alarm message sound is created by the synthesized voice creating unit 12-1, and is output from the speaker 14 via the audio output processing unit 13. Warning message "A101 Turbine speed 36
"50> 3600 rpm".

Next, with reference to FIG. 12, processing when a level 1 alarm is issued will be described. Alarm determination unit 6-1
Outputs a "current value", a "limit value", an "alarm state", and an "input point number" of the process data when it is determined that an alarm occurs at the input point number A100 of the process data.

The alarm level judging unit 6-6 receives the output signal from the alarm judging unit 6-1 and refers to the alarm level database 6-7 for the alarm level of A100, whereby the alarm level is 1: general. Make sure that. In this case, the alarm level determination unit 6-6 does not output anything to the alarm processing unit (for voice) 6-3 '. As a result, the alarm message with the alarm level of 1 is not voiced.

As in the first embodiment described above, when all the alarm messages are reported by voice, there is no problem if the plant alarms are sporadic, but when the alarms occur frequently, the alarm notifications continue. There is a fear of not knowing what is important.

However, in the case of the second embodiment, the voice notification is made only when the important alarm is judged. Therefore, if the voice notification is heard, it is necessary to grasp the main cause of the plant abnormality. You can

(Third Embodiment) Next, a third embodiment will be described with reference to FIGS. 13 and 15. In the present embodiment, a re-notification request processing function is added to the first embodiment.

In FIG. 13, the alarm monitoring processing unit 6-C is provided.

The message data is read from the message history recording means 6-8, and the synthesized voice creating section 1 is read.
In 2-1 the voice data is created again, and the voice output processing unit 1
The alarm 14 is re-notified from the speaker 14 via 3.

Next, the processing of the voice re-notification request will be described in detail with reference to FIGS. FIG. 15 shows an example of the re-notification request process. For example, the message “A101 Turbine rotation speed” indicating that the input point number A101 has returned to normal.
When "3600 rpm normal return" is reported, the message history recording means 6-8 records the date and time of occurrence, the input point number, the alarm state, etc., as shown in FIG.

The voice re-report request processing section 17-1 displays the re-report request dialogue contents on the display device 10 via the dialogue processing section 16. For example, when the operator requests re-notification of the last one message via the input device 15, the voice re-notification request processing unit 17-1 sends the text data of the message from the message history recording means 6-8. The data is read and output to the synthesized voice creating unit 12-1.

As a result, the voice data created by the synthesized voice creating unit 12-1 is transmitted from the speaker 14 via the voice output processing unit 13 to "A101 turbine speed 3600.
"rpm is returned to normal" is voiced again.

As described above, according to the present embodiment, when a voice notification of alarm generation / return to normal is given in the plant,
Even if the operator fails to hear the message or cannot hear the message sufficiently, the operator can easily make a re-notification by requesting a dialogue with the process computer, whereby the alarm content can be grasped and reconfirmed.

(Fourth Embodiment) Next, a fourth embodiment will be described with reference to FIGS. Figure 1
6 is a block diagram of the present embodiment, in which an emergency call processing means for external contacts is added to the second embodiment.

It is determined whether or not the alarm level is an important alarm level. Then, the alarm level determination unit 6-6 outputs the data related to the alarm to the alarm processing unit (for voice) 6-3 ′ for the items for which the alarm level is determined to be important.

The alarm processing unit (for voice) 6-3 'creates a voice notification message and synthesizes a voice by the voice creating unit 12-1.
Output to. The synthesized voice creating unit 12-1 reports the voice data created by the synthesized voice creating unit 12-1 from the speaker 14 via the voice output processing unit 13 and also outputs it to the emergency call determination processing unit 18-1. .

Reference numeral 18-2 is a contact information database which stores the telephone number of a mobile terminal which can be received by voice such as a mobile phone or PHS of a contact person such as an operator or an engineer in case of emergency. It is to be registered in advance. FIG. 17
[Fig. 3] is a diagram showing an example of a contact database, in which the names of persons concerned and the contact telephone numbers are recorded.

When the emergency call determination processing section 18-1 receives the notification of the occurrence of the emergency warning from the synthesized voice creating section 12-1,
The telephone number of the mobile terminal of the contact is read from the contact database 18-2, the line is connected to the mobile phone 20 via the communication device 19 such as a modem, and the synthesized voice creating unit 12-1.
The alarm message voice created in step 1 is notified to the persons concerned through the mobile phone 20.

Regarding the notification of the occurrence of the emergency alarm to the emergency notification determination processing section 18-1, instead of receiving it from the synthesized voice creating section 12-1 as described above, it is directly received from the alarm processing section 6-3 '. Of course, it may be changed to. (The same applies to the fifth to seventh embodiments) As described above, according to the present embodiment, in the event of an emergency when an important alarm occurs, the process computer sends a notification to the persons concerned. In addition to being able to quickly contact those involved not in the main control room, it is also possible to reduce the work of contacting the personnel involved by the shift operator, thus reducing the load on the shift operator in an emergency. You can

(Fifth Embodiment) Next, a fifth embodiment will be described with reference to FIGS. In the present embodiment, as shown in the configuration diagram of FIG. 18, the determination content of the alarm level determination unit in the fourth embodiment is subdivided and the processing in the emergency notification determination processing unit is performed according to the alarm level and system. It was changed to specify the contact information.

In the alarm monitoring processing unit 6-E, the alarm level determination unit 6-6 'determines an alarm level such as important or general as in the second embodiment, and also classifies the plant system of alarm items. Then, the determination result is output to the alarm processing unit (for voice) 6-3 ′.

The alarm processing unit (for voice) 6-3 'creates voice notification message data and combines the above-mentioned alarm determination result with the voice notification message into the synthesized voice creation unit 1.
Output to 2-1. The synthesized voice creating unit 12-1 outputs the created voice data to the speaker 1 via the voice output processing unit 13.
In addition to reporting from No. 4, voice data and the above warning determination result are output to the emergency call determination processing unit 18-1.

The emergency call determination processing section 18-1 reads the above-mentioned alarm determination result from the synthesized voice creating means 12-1 and shows in detail the related persons who match the alarm level and system of the generated alarm item in FIG. Contact database 18-2
