Is set up to suit the operator's skill level, such as "Open processing", "Start processing", and so on. "Therefore, the operator is irritated with excessive information or lacks information. It will not be impossible to judge the operation.

Similarly, a screen suitable for the operator's skill level is output in the screen output, and a message suitable for the operator's skill level is output in the message output. Can be obtained.

FIG. 7 shows the relationship between the screen association data storage unit 31 and the screen data storage unit 51 when the processing type is screen output, and the message association data storage unit 32 when the processing type is message output. FIG. 8 shows the relationship with the message data storage unit 61.

In FIG. 7, it is assumed that speaker XXX is an operator with high skill level, speakers belonging to group YYY are operators with low skill level, and unspecified speakers are visitors. When the screen output of the tank screen 1 is requested, the detailed screen A is displayed to the speaker XXX and the screen A is displayed to the speakers belonging to the group YYY.
The CRT display device 4 displays a screen B in which unnecessary information is deleted for operators with lower skill levels, and a screen C in which information that should not be disclosed to general observers to observers is deleted. As described above, the screen output processing unit 50 reads the screen data from the screen data storage unit 51 based on the screen connection data G001, G101, and G201 corresponding to the speakers stored in the screen connection data storage unit 31. And is output to the CRT display device 4.

The message output is automatically performed by the message output processing unit 60 according to each speaker according to the situation of the plant. For example, as shown in FIG. 8, when there are status changes 001 to 100 of the tank 1, the message output processing unit 60 does not require this message for the speaker XXX,
A speaker belonging to the group YYY and an unspecified speaker are required to read predetermined message data from the message data storage unit 61 with reference to the message association data stored in the message association data storage unit 32, and to perform CRT.
Output to the display device 4 and the audio output device 9.

The output request from an input device such as the keyboard 5 or the optical scanning type contact detector 6 which cannot be specified by the operator is the same as the default output request, for example, the output request from the unspecified speaker. It is possible to deal with it by setting it to output things.

On the other hand, a voice operation for device operation (eg, "device R emergency stop" as shown in FIG. 5 (step 5
01)), the processing unit 40 for giving permission / inhibition of device operation is activated by the speaker, and the information (step 502 in FIG. 5) acquired from the voice data input processing unit 20 causes the speaker to operate. Level determination processing 400
At, the speaker authority data stored in the speaker authority data storage unit 41 is referred to, and it is determined whether or not the speaker has the operation right for the device that the speaker is operating.

If it is determined in the speaker level determination processing 400 that the speaker cannot be operated, or if there is voice data that cannot be converted, a message to that effect is output by the voice output device 9 or the CRT.
It is output as a message through the display device 4.

Here, in the speaker authority data storage unit 41,
As shown in FIG. 9, each speaker is associated with whether or not each operating device can be operated.

The control information output processing unit 80 stores in the operating device data storage unit 81 the judgment as to whether or not the operation requested for the actual device is appropriate according to the device specifications and the output to the plant controller 2. Refer to the operating device data that has been set.

For a device operation request from an input device such as the keyboard 5 or the optical scanning type contact detector 6 which cannot be specified by the operator, the same control information as the device operation request from the default speaker, for example, an unspecified speaker is sent. By setting it, it becomes possible to respond.

As described above, since the operating device which can be operated by the voice operation can be changed according to the skill level of the operator, it is possible to prevent the erroneous operation of the operator having a particularly low skill level and reduce the stress caused by the fear of the erroneous operation. It will be possible.

[0073]
