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

FIG. 1 is a block diagram showing a configuration of an embodiment of a plant operation support device according to the present invention.

As shown in FIG. 1, in the plant operation support device 16, the sensor 1 is for recognizing an operator, and a fingerprint sensor, a retinal sensor, an ID card sensor and the like are used. Data from the sensor 1 is input to the operator identification unit 2 to determine the operator, that is, the person who is operating. The microphone 3, the keyboard 4, and the mouse 5 are connected to an input processing unit 6, and the input processing unit 6 interprets a question or instruction from an operator based on data input from the microphone 3, the keyboard 4, and the mouse 5. Is done. The plant state monitoring unit 7 monitors the state of the plant and the state of occurrence of an alarm.

The question or instruction content interpreted by the input processing unit 6 is sent to the input language processing unit 8 and subjected to language processing. The input language processing unit 8 performs a matching process with the question or instruction template stored in the template database 9. The result is sent to the data processing unit 1
0, and if there is an ambiguous part, that is, a part missing as information in the question or instruction content in the comparison with the template, a process of compensating for the insufficiency is performed.

Data from the operator identification unit 2 or data from the plant state monitoring unit 7 is used as data for compensating for the missing part. Further, the operation database 11 stores the past questions and instructions of the operator, the answers and operation contents at that time, the equipment and business contents in charge of the operator, and the like. These data are also stored in the vague data processing unit 10. Is used as data to make up for the missing part.

The data processed by the ambiguous data processing unit 10 is sent to an answer creating / operation executing unit 12, where an answer to an operator is created and an operation for a plant is executed. The answer and the result of the operation are sent to the output processing unit 13 or the plant state monitoring unit 7 and converted into voice and output from the speaker 14 or output to the CRT 15 or operation output to the plant. ing.

Next, this operation will be described with reference to FIGS.

FIG. 2 shows an example of an unambiguous question and answer. As shown in the figure, in both questions 1 and 2, the contents of the question include all information necessary for answering, and there is no missing information in the comparison with the template. Therefore, the ambiguous data processing unit 10 does not need data for supplementing the missing part, and can answer as shown in the answer 1 and the answer 2 in FIG.

FIG. 3 shows an example of a question containing an ambiguity or a question which is answered by comparing it with a past question, and an example of an answer.

FIG. 2A shows an example in which a question is answered from a conversation flow while supplementing a lacking part of a question. That is, the anonymous data processing unit 10 analyzes the contents of the questions or instructions of the operator, stores them in the operation database 11 in chronological order, and determines the tendency of the inquiries or instructions in the annihilation data processing unit 10. Answer the entered question or instruction. Note that the tendency of the question or instruction content includes, for example, direction, magnitude, increase / decrease, date / time,
There is a context of the order of the device or device number. In this case, it is usually preferable that the operator identifying section 2 automatically recognizes who is performing the operation, and determines the tendency of the question or the instruction content for each operator. (However, if multiple operators are working together to monitor and operate on the same object,
Since different operators may input questions alternately for the same object, it may not always be necessary to determine the tendency of questions or instructions for each operator. In the case of FIG. 9A, in the question 1, as described above, there is no information that is insufficient in the content of the question, so that it is not necessary to supplement the information, and the answer can be created as the answer 1. When the question 1 is input, the contents of the question 1 are stored in the operation database 11.

Then, the same operator asks question 2
Is input, from the information "What is the next pump?", The information for identifying the device is insufficient, and the information on the type of pump is insufficient. However, since the previous question, ie, Question 1, was “water distribution pump”, it is determined from the information of “next pump” that the type of pump does not change and is “water distribution pump”. Next, although there is also a shortage of information regarding the device number, the word “next” and the device number of the previous question, ie, question 1 were “No. 112”. No. 1
13 ".

Further, although there is also a shortage of information on what the quantity to be measured is, the previous question, ie, Question 1, is "flow rate", and is determined to be "flow rate" on the assumption that it does not change.
In this way, the information missing in Question 2 can be supplemented, and an answer can be created as in Answer 2.

Next, FIG. 3B shows an example of creating an answer by compensating for the insufficiency of the content of the question by the operator authentication.

The operation database 11 stores, for each operator, equipment or business contents which each operator is in charge of. Therefore, when the operator identifying section 2 automatically recognizes the operator who is inputting the question, the ambiguity data processing section 10 relates to the equipment and the contents of the work assigned to the operator inputting the question. Information on operation database 11
, It is possible to create an appropriate answer by supplementing the information without having to say the equipment name in the question.

That is, the plant has roles of an engineer, an operator, a maintenance person, an inspector, a facility manager, and the like.
Even for the same question, an appropriate and flexible answer according to the role of the person who asked the question can be created.

In FIG. 3B, both the question of Mr. A and the question of Mr. B are questions asking "What is the current situation?", But when the operator automatically recognizes that he is A. , A is the manager of the third management facility. So, for Mr. A's question, the current situation is
There is not enough information about "what", but from the role of Mr. A, this is a "third management facility", and it is possible to supplement this information and create a reply to Mr. A. it can.

Similarly, as for the question of Mr. B, the operator is automatically recognized as Mr. B, and when it is found that Mr. B is the production manager of the product 51, the operator is referred to as Mr. B based on this information. The answer to Mr. B can be created by compensating for the missing part of the question "Production quantity of product 51".

Next, FIG. 3C shows an example in which a response is created by collating with the contents of a past question.

That is, in the annihilation data processing unit 10,
The contents of the operator's question or instruction and the answer or operation at that time are analyzed and stored in the operation database 11 in chronological order.
At 0, when a question or instruction is input, it is determined whether there is a similar question or instruction. If there is a similar question or instruction content, an answer can be created by referring to the answer at that time.

Question 3 shown in FIG. 3 (c) does not necessarily have a missing part in the content of the question, but the operator who has already been recognized as Mr. A asks a question about "state of the chemical injection valve". So, as in answer 3,
The answer was created.

Next, FIG. 3D shows an example in which an answer is created by judging the situation of the plant.

That is, even if the operator inputs a question with a lack of content, such as not specifying the equipment, regarding the plant condition and the alarm, the plant condition is checked.
It responds to the status of the device and the contents of the warning that are likely to be applicable.

The plant state monitoring section 7 monitors the state of the plant and the state of occurrence of an alarm, and sends the information to the ambiguous data processing section 10. Therefore, as in Question 4 in FIG. 3D, even if the information for specifying the generated alarm is insufficient in the content of the question, the plant status monitoring unit 7 sets the plant to the vague data processing unit 10. From the information on the state of the alarm and the state of occurrence of the alarm, "T
231, and a response can be created as in response 4.

[0037]

According to the plant operation support system of the present invention, it is automatically interpreted according to the flow or situation of the conversation at that time only by asking the minimum necessary questions and instructions.
A comfortable operation environment can be provided even for a person unfamiliar with the keyboard or in an emergency.
