Step S401: The second acquisition means 238 acquires, for example, second voice data in which conversations between users in the plant are recorded via the communication unit 21. In the second embodiment, the recording of the conversation is performed by the mobile terminal 10 of each user, but the recording is not limited to this, and is performed by an arbitrary device such as a recording device installed in the central control room of the plant. Is also possible.

Step S402: The registration means 239 detects words that are not registered in the dictionary data from conversations between users and registers them in the dictionary data based on the second voice data. Specifically, the registration means 239 performs natural language processing such as morphological analysis on the second voice data, and detects each word appearing in the conversation between users. The registration means 239 collates each detected word with a word included in the dictionary data, and detects a word not registered in the dictionary data. The registration means 239 may automatically register the detected unregistered word, or may register it according to the user operation.

As described above, according to the plant management system 1 according to the second embodiment, words that are not registered in the dictionary data are detected from conversations between users and registered in the dictionary data. Therefore, since the accuracy of voice recognition is improved by enriching the dictionary data, the technique related to voice operation in the plant is further improved.

Step S505: The determination means 241 determines whether or not to execute the operation instruction detected by the first detection means 235 in step S504 based on the authority information of the user who utters the operation instruction. Specifically, the determination means 241 determines whether or not the execution of the operation instruction is permitted by the authority of the user by referring to the authority information. When it is determined that the execution of the operation instruction is permitted, the determination means 241 determines that the execution of the operation instruction is permitted (step S505-Yes), and the process proceeds to step S506. On the other hand, if it is determined that the execution of the operation instruction is not permitted, the determination means 241 determines that the execution of the operation instruction is not permitted (step S505-No), and the process proceeds to step S507.

Step S506: The output means 236 outputs an operation instruction to the plant equipment 30 via the communication unit 21. The operation of the plant equipment 30 is controlled according to the operation instruction. Then the process ends.

Step S507: The determination means 241 discards the operation instruction for the plant equipment 30. Then, the process ends without the operation instruction being output to the plant equipment 30.

As described above, according to the plant management system 1 according to the third embodiment, whether or not to execute the operation instruction for the plant equipment 30 is determined based on the authority of the user who utters the operation instruction. Therefore, the possibility of inconvenience such as execution of an operation instruction erroneously spoken by an unauthorized user is reduced, and thus the technique related to voice operation in the plant is further improved.

The 237 and the third storage means 240 may include a memory.

Further, in the above-described embodiment, a configuration for detecting an operation instruction to the plant equipment 30 by a user's utterance has been described. However, the operation instruction is not limited to the plant equipment 30, and for example, an operation instruction to the mobile terminal 10 and / or the server 20 due to a user's utterance can be detected.

Further, in order to function as the mobile terminal 10 or the server 20 according to the above-described embodiment, a general-purpose information processing device such as a computer or a mobile phone can be used. The information processing device stores a program describing processing contents that realize each function of the mobile terminal 10 or the server 20 according to the embodiment in the memory of the information processing device, and the processor of the information processing device executes the program. This can be achieved by reading and executing.
