DETAILED DESCRIPTION OF THE INVENTION

 [Object of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voice event reporting device for reporting an event by voice in operation monitoring of various plants such as a power plant.

[0002]

2. Description of the Related Art FIG. 9 shows a configuration example of a conventional voice event notification device.

[0003] The monitoring target 2 of the voice event notification device 1 is:
For example, power plants, chemical plants, and other plants. The console 3 inputs a human operation to the audio event notification device 1. The input unit 4 inputs a state quantity of a plant or the like in the monitoring target 2. Event determination means 5
An occurrence of an event is determined based on data from the input unit 4. Here, an event refers to an event such as a change in the state of the plant based on external conditions such as opening and closing of a valve in the plant, ON / OFF operation of a motor, and the like, for example, start or completion of a certain process.

[0004] The sound piece editing means 6 sends a message No. from the event determination means 5. Upon receiving the message, a combination of speech pieces corresponding to a message stored in the message table 7 described later is output. The message table 7 stores each message No. Is stored as the combination of the sound pieces corresponding to. The voice output control unit 8 receives the combination of the voice units output from the voice unit editing unit 6 and outputs voice data corresponding to the voice unit from the voice unit memory 9 as voice from the speaker 10.

In the above configuration, when an event occurs and the operator is notified of the occurrence, the following processing is performed.

First, the event determining means 5 determines that an event has occurred by a message No. To the sound piece editing means 6. The sound piece editing means 6 outputs the message No. of the message table 7. Is determined, and a combination of a plurality of sound pieces No. is determined. A voice output instruction is issued to the voice output control unit 8 in the form of.

[0007] The voice output control unit 8 controls the sound piece No. Are sequentially input to the speaker 10 as voice data while inputting the voice piece data corresponding to. As described above, the message is processed by the combination of the sound pieces, and the message is expressed by the combination of the sound pieces. A voice unit shared by a plurality of messages has only one voice unit data in the voice unit memory 9 to reduce the capacity of the voice unit memory 9.

[0008]

However, the above-described apparatus has the following problems.

That is, there are cases where events on plant operation occur intensively in a short period of time, and a large number of messages to be reported occur at once. Unlike the event information using a display device or the like, the event notification by voice cannot perform a plurality of notifications at the same time. Also, the report itself requires some time. Therefore, when messages to be reported are concentrated at one time, a message that is waiting to be output is generated.

[0010] This causes the following problem.
For one, the message output is processed in chronological order, so that even important messages are kept waiting until the output of the previously output message is completed. For this reason, there is a problem that the notification is delayed and the operator cannot recognize the occurrence of the important event at an appropriate time.

The other is that, even though the system has already been started, a notice of operation for the plant, for example, a message such as "Start A pump" is delayed, and the notice is given to the operator. There is a problem of misunderstanding. If the operation itself is delayed to solve this, the operation of the plant will take a long time to operate.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a voice event reporting device that eliminates delays in outputting important messages and prevents misunderstandings by operators due to delays in outputting messages. [Configuration of the Invention]

[0013]

According to the present invention, an input means for inputting plant data, an occurrence of an event is determined based on the data input by the input means, and a message No. corresponding to the generated event is determined. Event determining means for outputting the message No. , A message table in which a combination of speech pieces corresponding to each of the speech pieces is stored in advance for each message, a speech piece memory in which speech data corresponding to the speech pieces is stored for each speech piece, and a message No. output by the event determination means. From the message table based on the message No. A voice unit editing unit for extracting a voice unit combination corresponding to the voice unit; a voice output control unit for obtaining voice unit data from the voice unit memory in accordance with the voice unit combination extracted by the voice unit editing unit; Control unit 8
In the voice event notification device comprising a speaker for giving a voice notification of an event by the output of
o. And a priority table that stores in advance the priority of performing the voice notification, and a message number that is waiting for the voice notification after the occurrence of the event. , A timer for measuring the time from the occurrence of the event to the time of the voice notification, and a message No. from the event determination means. Is input from the timer and the message No. from the priority table. And this No. A voice output timing determination unit that sets a priority corresponding to the flag and an incomplete flag of the voice notification, and saves the flag in the output waiting message table.
In the message table, a notice message for notifying that the operation of the plant or the like is started or a completion message for notifying that the operation of the plant or the like has already been completed is the message No. Is provided in advance in correspondence with the message number. Means for resetting a voice report incomplete flag corresponding to the output waiting message table when voice notification is made, and voice output data selection for selecting the highest priority message stored in the output waiting message table. And the message No. selected by the voice output data selection means stored in the output waiting message table when the data of the notice message or the completion message held in the message table is the notice message. Calculating means for calculating a time difference between an event occurrence time and an output time corresponding to the event, and outputting the notice message to the voice output control unit when the time difference calculated by the calculating means does not exceed a predetermined time. And a means for outputting the completion message to the audio output control unit in place of the notice message when the time difference exceeds a predetermined time.

[0014]

With the above arrangement, the voice output timing determining means determines the message number from the priority table. And the event occurrence time are stored in the output waiting message table. The sound piece editing means searches the output waiting message table, and outputs a sound from the message waiting for output to the sound output control unit based on the message table in accordance with the message so as to output a sound from the message with the highest priority. Output. At this time, the difference between the event occurrence time and the actual message output time is calculated, and if a predetermined time has elapsed and the message is an operation notice message, the message is changed to a completion message and the sound is output. Outputs the sound piece to the control unit. Thus, when a large number of events occur at one time, messages with higher priority are sequentially output. Further, when the output of the message is delayed and the operation of the plant is completed, the notice message is not output.

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a voice event notification device according to an embodiment of the present invention. 9 denote the same or corresponding parts. 9 is different from FIG. 9 in that the priority table 11, the audio output timing determination means 12, the timer 13, and the output waiting message table 14 are provided.
This is the point that was added.

The priority table 11 indicates that each message N
o. And the priority output order. The voice output timing determining means 12 inputs the priority of the event to be generated from the priority table 11 and the event occurrence time from the timer 13, and outputs the message No. corresponding to the event. At the same time, the output message is stored in the output waiting message table 14. The timer 13 outputs the event occurrence time, and measures the time until the notification becomes possible. The output waiting message table 14 stores a message No. indicating whether the message is waiting for output. The event occurrence time and priority are stored.

Next, the operation of the present embodiment will be described.

First, the input means 4 receives an analog quantity (for example, temperature and pressure) and contact information (for example, opening and closing of a valve in the power plant, an operation switch pressed by an operator) from the power plant or the like to be monitored 2. ON / OFF) is input when a periodic or change in state is detected, and the value is output to the event determination means 5.

The event determination means 5 performs various arithmetic processing (whether or not the analog value exceeds a certain value, AND / OR operation, etc.) using these input signals, and determines the occurrence of an event based on the result. judge. Then, a message corresponding to the event is given as a message No. To notify the audio output timing determination means 12. For example, using the logic shown in FIG. 2, the pump outlet valve is opened and the control power is turned on.
And output when the pump start button is ON. As a result, the message No. “Pump starts” appears. 3 is output to the audio output timing determination means 12.

The above-described audio output timing determining means 12
Will be described with reference to FIG.

The voice output timing determining means 12 receives the message No. from the event determining means 5. Is checked as needed (101). Message No. Is input (102). Next, the time is input from the timer 13 (103). Further, as shown in FIG. 4, the priority of the message is input from the priority table 11 (104). This priority table 11
It is a data structure, and the message No. Column 11a is stored as a numerical value (the smaller the number, the higher the priority). For example, in the example of FIG. The priority “2” corresponding to “3” is stored in the priority table 11.

Next, the information is set in an output waiting message table 14 as shown in FIG. 5 (105).

The data structure of the output waiting message table 14 is as follows. Column 14b, an event occurrence time column 14c, and a priority column 14d, and a flag column 14a indicating whether or not the registered message request has been processed by the sound piece editing unit 6 described later. ing. Then, a flag indicating whether or not the message has not been processed is set in the flag field 14a. In this example, the message No. "3", priority "2",
Event occurrence time “10:24:18”, flag =
This shows a case where it is registered as “0” (unprocessed). At this time, the message No. “15” registered in the first row is registered as unprocessed (flag = “1”), and all other messages are processed (flag = “0”).

The information set in the output waiting message table 14 in this way is processed according to the flowcharts shown in FIGS.

FIG. 7 is a detailed flowchart of the audio output data selection process in FIG.

The sound piece editing means 6 searches the output waiting message table 14 and selects audio output data to be output next (201). In this selection process, as shown in FIG. 7, first, each message request on the output waiting message table 14 is sequentially read (301). Thus, it is determined whether the flag is set (302). In this determination, a flag is set, that is, an unprocessed flag is input (303). The message requests having the highest priority on the output waiting message table 14 are sequentially determined (304). As a result, the highest priority No. Message No. in order. Is stored (30
5).

On the other hand, when the flag is not set or when all the data are checked, the processing ends (30).
2) (306).

Next, returning to the processing shown in FIG. 6, when a message to be output is determined, it is determined whether or not the message processed immediately before is still outputting voice (202). After the output is completed, the output process starts. For this output,
It is determined whether the message is a notice message or a completion message by referring to the message table 7 having a data structure as shown in FIG. 8 (203). The message table 7 stores the message No. Column 7a, notice / completion column 7b, completion message No. Column 7c, voice No. Column 7d. In the case of a notice message in this determination, the difference between the event occurrence time and the output time is calculated with reference to the event occurrence time on the output waiting message table 14 (204).

As a result, if the time difference has passed the predetermined time α or more, a completion message is output instead of the notice message. That is, the completion message No. on the message table 7 is displayed. Referring to the column 7c, processing is performed to replace the completion message corresponding to the notice message, for example, "pump started" with "pump started" (207).

In the voice output control unit 8, the sound piece No. The sound is output to the speaker 10 while inputting the sound unit data from the sound unit memory 9 to the sound unit corresponding to. If the time difference is equal to or less than the predetermined time α, a notice message is output (20).
6).

In the example shown in FIG. As a process for "3", the notice / completion column 7b is checked. Here, it is "notice". Therefore, the output waiting message table 1 shown in FIG.
The difference between the event occurrence time “10:24:18” of No. 4 and the output time is calculated. In this case, the time difference is a fixed time α
If the time has elapsed, the completion message No. The completion message No. stored in the column 7c “25
8 to output the message registered in message No. "258" from speech unit No. "18".
“102” is output to the audio output control unit 8.

On the other hand, if the time difference has not passed the fixed time α, the message No. The sound piece No. registered in “3” “19” ‥‥‥‥ “101” is output. Note that, in this example, as shown in FIG. "15" (first line)
And the message No. There are two “3” (second line). Here, the message No. "3" is processed first because the order of occurrence is late but the priority is high.

As described above, when a large number of events occur at one time, voices are sequentially output in descending order of priority. In addition, if the output is delayed due to a low-priority message, there is no need to output a notice message or wait for the operation itself after the operation has already been completed.

[0035]

As described above, according to the present invention, even when events occur in a concentrated manner in a short time and a large number of messages to be reported occur at one time, the operator is important. The occurrence of an event can be recognized in a timely manner. Furthermore, there is no possibility of erroneous recognition of the message content due to a delay in output of the message.
