TECHNICAL FIELD The present invention relates to a voice notification device that can be used in an information processing system that controls a plant such as a chemical plant, a thermal power plant, or a nuclear power plant.

"Prior Art" In plants such as a chemical plant, a thermal power plant, and a nuclear power plant, a plant automation system for automating the operation thereof has been actively adopted. In this system, the operating state of the plant, the operation guide, and the like are displayed on the CRT and announced by voice from the speaker, so that the man-machine interface is improved. Especially, the voice notification device is a CRT.
It does not require the space required for installing the display section such as, and is widely used from such a point.

[Problems to be Solved by the Invention] However, the conventional voice notification device uses a speaker arranged in the central control room to transmit voice information. For this reason, (i) in an emergency call, there is often a time conflict with the ringing of the warning buzzer, which makes it difficult to accurately transmit the content. In addition, (ii) it may be difficult for a person at a place such as an upright board where various instruments are arranged to hear voice information because of noise generated by the instruments. Especially when using this speaker, if you are reading aloud to associate the data displayed on the display in the central control room with the instruction contents of the instrument, you may hear the data incorrectly, and the device calibration may be accurate. There was a problem that I could not do it. Furthermore, (iii)
Of the voice information sent from the speaker, there is much information that only a specific person needs, and it is unnecessary and noise for other people. (Iv) Even if you want to get the necessary information immediately, you have to wait until the information that is being sent for another person is finished, and you cannot use your time efficiently. There was also.

Therefore, an object of the present invention is to provide a voice notification device that enables each person to easily and surely obtain his or her necessary information.

"Means for Solving Problems" In the present invention, (a) data processing means for measuring each state of the plant and processing the data obtained thereby,
(B) Connection terminals arranged at various places in the system for individually connecting the audio input / output devices that individually output and input audio, including a headphone-type speaker and microphone
(C) A speaker for indoor broadcasting, which is arranged so that the user can listen regardless of the use of the audio input / output device at various points in the system, and (d) audio input / output that detects the connection of the audio input / output device to the connection terminal. When the connection of the voice input / output device is detected by the device connection detection means and (e) the voice input / output device connection detection means, a plurality of predetermined questions that can be answered by affirmative or negative words can be input. Question output means for outputting a voice to the connection terminal connected to the output device, and (f) When voice responses from the voice input / output device connected to the connection terminal to the question of the question output means, those responses Connection terminal data content correspondence relation registration means for registering a predetermined one of data processed by the data processing means as data content corresponding to the connection terminal, and (g) data processing Of the data processed by the means, the data content output means for outputting the respective data content registered in the connection terminal data content correspondence relationship registration means to the corresponding connection terminals by voice, and (h) data processing means. The voice notification device is provided with a simultaneous output means for outputting a predetermined one of the data processed in (1) by voice to all of the indoor broadcast speakers and the connection terminals.

Then, the operator can connect his own voice input / output device to the connection terminal at a desired place so that he can hear only the data he needs, and if everyone does not know the urgent content. For specified data that does not occur, sound is output from both the indoor broadcast speaker and the audio input / output device so that people who are not connected to the audio input / output device can also hear the necessary data. ing.

[Examples] The present invention will be described in detail below with reference to examples.

FIG. 1 shows a main part of a main control room using a voice notification device. In this central control room, control panels 1-3
And upright boards 4-9 are arranged. Control panels 1 to 3 are for controlling the plant, and here various switches and C
RT etc. are arranged. The upright boards 4 to 9 are provided with a large number of measuring instruments for measuring information obtained from a plant (not shown). A total of 13 connection terminals 11-1 to 11 to 13 are arranged on the control panels 1 to 3. Upright boards 4-9 have a total of 20 connection terminals 11-14-1.
1-33 are arranged. FIG. 2 shows the arrangement of the connection terminals in the control panel. The connection terminal 11 is attached to the front end portion of the horizontal operation unit 12 of the control panels 1 to 3, for example. If necessary, a plug for connecting the audio input / output device will be inserted here.

FIG. 3 shows a voice input / output device used in this embodiment. The audio input / output device 14 is provided with a headband 15 for fixing the audio input / output device 14 to the operator's head, a headphone type speaker 16 is provided at one end, and a volume 17 is provided at the other end. A regulator 18 is arranged. A microphone 19 is attached to the tip of the volume controller 18.
The support tool 21 in which is disposed and the cord 23 in which the connection plug 22 is disposed at one end are attached. Speaker 16
With this voice input / output device 14 attached to the head,
The microphone 19 is placed so as to face one of the ears of the operator.
Is designed to be placed near the mouth. The reason why the two speakers 16 are not provided for both ears is to allow one ear to hear the instructions of the other operator.

FIG. 4 shows a main part of an electric circuit of the voice notification device of this embodiment. The voice notification device is equipped with a CPU (central processing unit) 25. The CPU 25 is connected to each unit via a bus 26 such as an address bus and a data bus, and is adapted to process various data necessary for voice announcement. ROM 27 is a read-only program that stores a program for enabling voice notification.
It is a memory. The RAM 28 is a random access memory for temporarily storing processed data. The first I / O 29 is an input / output port for connecting a switch or a CRT (both not shown) on the control panel and the bus 26 described above. The second I / O 31 is an input / output port for transferring data from a plant (not shown) collected in the collecting device 32 for collecting data to the bus 26 in a predetermined order. The third I / O 33 has connection terminals 11-1 to 11-1.
An input / output port for fetching data from 1-33 and outputting data to a desired connection terminal.

A method of using the voice notification device having such a configuration will be described with reference to FIG.

A person who intends to use the voice notification device prepares the voice input / output device 14 and inserts the connection plug 22 into the connection terminal 11 closest to the working place. The CPU 25 scans the connection status of each of the connection terminals 11-1 to 11-33. When the connecting plug 22 is connected,
The connection terminal, for example, the connection terminal 11-1 is stored in the RAM 28 (step). After that, it is monitored whether there is a voice input from the voice input / output device 14 (step).

By the way, the operator, after connecting the plug 22 for connection, inputs a command for causing the voice notification device to perform the desired work by voice input. This instruction includes (i) "reading process" instruction, (ii) "limit value setting" instruction, (iii)
There are four types of commands: "limit value setting cancellation" command and (iv) "end" command.

First, the "reading-out process" command is a command for uttering the data prepared for reading out of the data stored in the RAM 28 of the voice notification device by using a voice output circuit (not shown). When the operator utters "reading-out processing" to the microphone 19 and this is recognized by the CPU 25 (step; Y), the CPU 25 checks the item to be read out next (step).

If items such as (i) reactor pressure, (ii) reactor water level, (iii) feed water flow rate, (iv) generator output, etc. are listed, "is it reactor pressure?" Questions such as “yes” or “no” such as “reactor water level?” Are sequentially output from the speaker 16. In this way, the parameter for which the operator answered "Yes" is selected. Next, the CPU 25 checks whether or not the reading should be performed periodically (step). That is, when the question "is it periodic?" Is asked and the word "no" is uttered by the operator, for example, the reactor water level is read only once (step). Then, the voice notification device is in a standby state until another command is issued (step).

On the other hand, the question "is it periodic?"
If, for example, the reactor water level is read once (step), the reading is continued until the “end” work described later is executed (step). If an "end" command is issued at the time of reading,
The device returns to the initial state when the reading is finished. Of course, the operator uses the connection plug 22 for the connection terminal 11
If you withdraw from -1 etc., you will be free from the reading work at this point.

When the operator inputs a "limit value setting" command by voice (step; N ,; Y), item checking is performed for which item the limit value is to be set (step). This checking method is performed in the same manner as in the case of the "read-aloud processing" command. When the item is determined, the program for setting the limit value is executed (step). For example, when setting a limit value for the reactor water level, the numerical value is input by voice, and the numerical value recognized by the CPU 25 is output from the speaker 16 to confirm this. Then, this limit value is registered in the RAM 28. R
If the AM 28 is backed up by a battery, its value can be saved even when the power is cut off. When the setting of the limit value is completed, the voice notification device returns to the initial state.

On the other hand, when the operator inputs a "limit value setting cancellation" command by voice (step, N, Y), the already set limit value is canceled. Also in this case, an item check is performed to determine which limit value should be released (step). After that, the program for releasing the limit value is executed (step).

Unlike the above, when the operator voice-inputs the "end" command (step, ..., N, Y), a predetermined end program is executed (step), and the voice notification device returns to the initial state. The above-mentioned reading ending work (step) is based on the execution of this ending program. The termination program is executed even when the operator pulls out the connection plug 22.

On the other hand, when the voice input does not correspond to any of the commands described above (step; N), an error message is output as voice (step) assuming that there is an undecipherable input, and the voice notification device is initialized. It will return to the state.

FIG. 6 is for explaining the warning operation when the limit value is set in the voice notification device. CPU2
5 (FIG. 4) reads each parameter value from the collection device 32 and writes it in a predetermined memory area in the RAM 28 (step in FIG. 6). The reading of the parameter value is performed at a predetermined sampling cycle, whereby the data content of this memory area is updated sequentially. If there is a parameter (item) for which the limit value has been set (step), the limit value for this parameter is compared with the corresponding data in the memory (step). If the limit value is exceeded, a warning message is output by voice (step). If the limit is not exceeded, no warning message will be output. The warning message is output not only from the speakers 16 of all the audio input / output devices in the connected state, but also from a not-shown speaker for private broadcasting.

"Effects of the Invention" As described above, according to the present invention, since each individual can obtain voice information that is personalized by the voice input / output device, the information can be acquired without delay. Since the voice is listened to by the headphones, there is no fear of making a mistake even in a place where the noise is relatively large. Further, since a plurality of connection terminals are arranged, not only can the voice input / output device be set at a desired place, but also a plurality of people can use this voice notification device at the same time. In other words, each operator can listen to only the data that he or she needs, overlapping in time.
The notification by voice can be effectively performed in a relatively short time.

Further, according to the present invention, since the indoor broadcast speaker is used together with the head-type audio input / output device, an operator who does not connect his / her own audio input / output device to the connection terminal must listen to the necessary data. can do. Further, in the present invention, the operator inputs the data content required by the operator from the terminal to which the voice input / output device is connected by voice response, and the required data content is transmitted to the connection terminal.
Therefore, even when the same operator moves within the system, he or she can specify and listen to the data that he or she needs at each position. Moreover, since input by voice response is performed as a response to a plurality of predetermined questions that can be answered with a word indicating affirmation or denial,
A simple circuit can reliably recognize these responses. Further, since it is only necessary to prepare a connection terminal for the voice input / output device in the system and it is not necessary to prepare a complicated input / output device such as a keyboard and a CRT, the whole system can be made easy to operate and inexpensive. Besides, it is not necessary to interrupt the work because the voice input / output device can freely use the hand while answering a question.
