Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data reading device for reading out plant information by voice in a process instrumentation control field and informing a user of the information.

[0002]

2. Description of the Related Art In a central control room of a large-scale plant such as a nuclear power plant or a thermal power plant, a large amount of process data is collected and necessary data can be checked instantaneously. On the other hand, at a plant site or the like, the information that can be checked there is limited, and the information is often checked by calling an operator in the central control room to obtain necessary information.

For example, when operating a local operation device when process data reaches a certain value, a telephone is connected between the central control room and the site, and a local operation is performed based on data read out by an operator of the central control room. May be implemented. That is, the operator in the main control room may need to take over the provision of information different from the original work.

In order to solve such a situation, various on-site portable terminals have been proposed. However, most of them are for displaying information on the screen, and the amount of data to be transmitted increases, or it is necessary to store data on the terminal side, which may increase the burden on the terminal side and impair portability. There is something. Further, in the field work, there are many maintenance and adjustment works of the machine, and there are cases where the hands cannot be released or the work is performed at a proper timing, so that the eyes cannot be kept away, and it is often inconvenient to provide information on the screen.

[0005]

However, such a situation is the same in the operation of the central control room which provides information centered on the screen, and when monitoring the change of the process data, the operator puts on the display. It is also often observed that data changes are continuously monitored in a state of being attached. In particular, when an abnormality occurs, it is not known how long it takes to reach the target value or whether the data changes significantly, so that it may be impossible to keep an eye on it.

In order to cope with such a situation, information providing means using voice has been proposed, and most of them are provided with voice output as shown in "Text-to-speech apparatus" (Japanese Patent Application Laid-Open No. 5-260082). It emphasizes how to speak in a natural way and does not mention how to use it.

Further, as an application to plant monitoring, a "monitoring system" (Japanese Patent Application Laid-Open No. 5-79951) and a "voice notification device" (Japanese Patent Application Laid-Open No. 8-241468) have been proposed. It is only used as an expression of information provision, and only mentions how to suppress information to be output.It does not mention control methods such as wording intervals and combinations of information. It is not really easy to use.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a data reading device capable of outputting read data at a timing that is easy to use in response to a user request.

[0009]

According to a first aspect of the present invention, there is provided a data processing unit for inputting and processing process data, and request information from a user of the process data and read-out data processed by the data processing unit. And a voice output unit that generates read-out data based on the data and outputs the read-out data to the outside. Processing means and data evaluation means for evaluating the process data and attributes taken in by the process data processing means to control a data transmission cycle based on a predetermined condition of plant state change; The unit, when data is sent in the transmission cycle controlled by the data processing unit,
There is provided a read-out data creating unit that creates read-out data based on process data and an attribute, and a control unit that controls the output timing of the read-out data created by the read-out data creating unit to the outside. . According to this means, the process data in response to the request from the user is taken in, and the transmission cycle of the data evaluated based on the process data and the change condition of the plant state is controlled. When data is input to the audio output unit in a controlled transmission cycle, read-out data is created, and the read-out data is controlled and output to the outside. As a result, read-out data based on the process data corresponding to the plant change state is created, and the read-out data is controlled and output at a timing that is easy for the user to understand. Therefore, information necessary for the user can be transmitted by voice at an accurate timing.

According to a second aspect of the present invention, in the data reading device according to the first aspect, the data evaluation means includes:
A means for controlling a data transmission cycle by comparing a reference value of a process data change rate provided for each process data with a change rate of the corresponding process data and evaluating the process data in accordance with the comparison result, or One of means for evaluating the process data in accordance with the deviation between the set value and the process data value and controlling the data transmission cycle is provided. According to this means, the process data is evaluated according to the change rate of the process data and the reference value of the change rate, or each deviation between the process data value and the set value, and the data transmission cycle is controlled. By this, the change state of the plant, that is, when the plant is changing suddenly, while shortening the data transmission cycle to quickly read out the change value of the corresponding process data,
When the plant is stable, the data transmission cycle can be lengthened. Therefore, the data required by the user can be read out at an appropriate timing according to the plant state.

According to a third aspect of the present invention, in the data reading device according to the first aspect, the data evaluation means controls a transmission cycle in accordance with a deviation between a predetermined target value and a corresponding process data value, and controls the transmission period of the process data. When the data arrives at the target value, notification of arrival at the target value is made. According to this means, when the process data is far away from the target value, the trouble of outputting unnecessary read-out data is suppressed. Further, as the process data approaches the target value, the data transmission cycle is shortened, and necessary data is notified to the user by voice in a detailed manner, so that the work efficiency can be improved.

According to a fourth aspect of the present invention, in the data reading device according to the first aspect, the data evaluation means evaluates event data related to the process data to be read and controls a data transmission cycle. . According to this means, the event data is evaluated, and in the case of an important event, the read-aloud data is repeated early as a short transmission cycle to notify the user quickly and reliably. On the other hand, in the case of an unimportant event, data to be read out as a long transmission cycle is read out at long intervals.

According to a fifth aspect of the present invention, in the data reading device according to the first aspect, the control means waits for more than a predetermined time to wait for a plurality of pieces of read data to compete without reading specific read data. In such a case, the corresponding data is deleted from the file of the reading list to prevent reading at inappropriate timing, or the specific data with high priority is left unread without leaving a predetermined time. Also, the data is not deleted from the file of the reading list, and the reading data is created by adding the elapsed time. According to this means, when a plurality of pieces of read-out data compete with each other, the read-out is stopped when a time for waiting for the read-out has elapsed for a predetermined time, so that reading-out at meaningless unnecessary timing is avoided. In addition, data having a high priority to some extent is read out with a delay time added even if the reading out is slightly delayed.

According to a sixth aspect of the present invention, in the data reading device according to the first aspect, when the plurality of reading data by the process data and the event data are in a waiting state due to contention, the control means may execute the data reading in descending order of priority. Or a data configuration to be read out according to the transmission cycle of the waiting time data to be read out. According to this means, when a plurality of data are on standby, the read-aloud data is output to the outside in descending order of priority. In this case, when the transmission cycle of the data to be read out is short, a short character string is output, and when the transmission cycle is long, the data is output as a long character string. Therefore, a large amount of read-out data is output within a limited time, and the waiting time can be reduced, which is more efficient.

According to a seventh aspect of the present invention, in the data reading apparatus according to the first aspect, the control means increases the priority of the process data which has not been read out for a certain period of time and has been put into a waiting state, and during reading of the event data. And a priority control means for appropriately controlling the priority in a standby state so that the priority of the process data is restored after the process data is read out. . According to this means,
When the reading wait state of the process data is long, the priority can be increased to interrupt the reading of the event data, and the process data can be read and output as appropriate.

According to an eighth aspect of the present invention, in the data reading apparatus according to the first aspect, the control means appropriately controls the priorities so that the specific reading data can be read continuously to some extent, so that the user can easily understand. Priority control means is provided. According to this means, since the specific data is read out continuously to some extent, different data is read out alternately, thereby avoiding a situation in which it is difficult for each user to understand the data. Therefore, the user can easily acquire the data required by the user by voice.

According to a ninth aspect of the present invention, in the data reading device according to the first aspect, when reading out data, there is provided means for displaying related data in conjunction with a voice output. According to this means, since voice output and related data are displayed, necessary information is transmitted to the user. Therefore, inconvenience such as viewing the display of the related data at another timing is eliminated.

According to a tenth aspect of the present invention, in the data reading device of the first aspect, means for converting a user's voice into character string data or means for inputting the character string data to the user is provided. In addition, character string data is added to the event data and the event data is output together with voice. According to this means, since the information intended by the user is added to the process data or the event data and is read out, the read-out data can be easily grasped.

[0019]

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

FIG. 1 is a hardware configuration diagram of a data reading apparatus according to a first embodiment of the present invention.
FIG. 3 is a functional configuration diagram of a corresponding data reading device.

In FIG. 1, in the data reading device, an audio output device 101 and a data server 102 are connected by a network 103, and data is exchanged between the audio output device 101 and the data server 102. I have.

The data server 102 inputs the process data of the plant, performs data processing based on the data processed and processed and the data requested by the user from the voice output device 101, and outputs the result as voice. The data is transmitted to the device 101.

The voice output device 101 receives user input and converts data transmitted from the data server 102 into voice and outputs the voice. The user's input may be received using a normal keyboard or pointing device or may be input using a voice input.

The network connecting the data server 102 and the audio output device 101 may be any network that can be used by a computer, and may be an Ethernet cable, a telephone line, a wireless LAN, or the like. Further, the data server 102 and the audio output device 101 may be on the same computer.

The audio output device 101, which is an audio output unit,
Specifically, as shown in FIG. 2, the input data processing means 1, the data transmission means 2, the input processing database F1, the transmission data processing means 7, the reading data creation means 8, the voice conversion means 9, the voice output means 10, It comprises a voice output database F2, a process data file F3, an event data file F4, a read data file F5, and an initial data file F6.

On the other hand, the data server 1 as a data processing unit
2, specifically, includes a data processing means 3, a process data processing means 4, a data evaluation means 5, a data transmission means 6, and a processing setting database F7, as shown in FIG.

In the audio output device 101, the event data 21 of the information desired by the user is input from the input data processing means 1. This data includes the name of the process data to be read, the target value of the process data, and the like. The input data processing means 1 converts the input data into a predetermined format to be transmitted to the data server 102 with reference to the input processing database F1. This event data 2
When a voice input is used as 1, a process of converting voice into data is also performed.

FIG. 3 shows an example of the format of the transmission data 50 transmitted from the audio output device 101 to the data server 102. As shown in FIG. There is a status indicating a state such as single-speech reading, the number of process data to be read, a name number, a target value flag indicating whether or not to set a target, and a target value for each process data. The data transmission means 2 transmits the data in the above format shown in FIG.

In the data server 102, data from the audio output device 101 is received, and the data processing setting means 3 makes settings for data processing with reference to the processing setting database F7. That is, the data processing setting means 3 receives the process data number and the target value to be processed from the transmission data 50, and abbreviates the data to be transmitted from the processing setting database F7, the numerical format, the unit, and the related plant event data. And settings,
The data priority, the change rate reference value, and the like are read.

When the transmission data 50 from the audio output device 101 includes the priority of the data, the priority is used. The process data processing means 4 fetches the designated process data and the related plant event data, and determines the rate of change (difference) of the periodically fetched data and the presence or absence of an event.

Next, the data evaluation means 5, which will be described later in detail, performs processing for evaluating the process data and attributes based on the predetermined plant change state and determining the cycle of the transmission data.

Subsequently, the data transmission means 6 transmits the data to the audio output device 101 when there is data to be transmitted. The data transmission here is divided into the following three.

1. Transmission of initial data Data accompanying the data value, such as the abbreviated name and unit of the process data to be read, is transmitted only once at the start of data transmission for each process data. FIG. 4 shows an example of the format of the transmission data 51 of the initial data. The data length of the transmission data, the number of process data to be transmitted, the name of the process data, the abbreviation of the process data, the unit, and the priority at the time of reading out the process data Is included. If the priority of the process data changes while the data reading is continued, the priority for the process data is retransmitted.

2. Transmission of process data The latest process data is transmitted at the transmission cycle determined by the data evaluation means 5. FIG. 5 shows an example of the data format of the transmission data 52 of the process data. The data length of the transmission data, the number of the process data to be transmitted, the data type for identifying whether the transmission data is the process data or the event data, and the process data And the numerical data of the process data.

3. Transmission of event data Transmits event data transmission data related to process data to be read out. FIG. 6 shows an example of the format of the transmission data 53 of the event data. The data length of the transmission data, the number of process data to be transmitted, the data type for identifying whether the transmission data is the process data or the event data, and the associated process The name of the data, the content of the event data to be read, and the priority at the time of reading the process data are included.

Next, in response to data transmission from the data server 102, the audio output device 101 first sorts transmission data. That is, in the transmission data processing means 7, the transmitted initial data, process data, and event data correspond to the initial data file F6,
Each file of the process data file F3 and the event data file F4 is stored in each data.

Here, the following data is written in each file. As the file writing time of the process data file F3 and the event data file F4, the reception time of the audio output device 101 at the time of data transmission is entered.

1. 1. Initial data file F6 Name, abbreviated name, unit, priority of process data 2. Process data file F3 Process data name number, numerical data, file writing time Event data file F4 Process data name number, event data, priority,
File write time

Next, a description will be given of the processing contents in the case where one process data is read out (for example, when only the reactor water level is sent).

FIG. 7 shows the processing of the transmission data processing means 7 and the read-out data creation means 8.

The audio server 101 has a data server 1
Process data is sequentially transmitted based on the transmission cycle set from 02, and only one data is overwritten on the process data file F3 by the transmission data processing means 7 (S1). Next, data is read from the process data file F3 (S2). Process data file F
3. If there is data in S3, create read-aloud data (S
4). Here, when the process data is read out, the contents of the read out process data file are deleted (S5). That is, the process data is read out only when there is data in the process data file F3 (S6). This eliminates the need for the voice output device 101 to manage the reading interval. Next, writing of data to the process data file F3 is performed by overwriting (new when there is no data in the file) every time data is transmitted.

In step S6, a determination is made as to whether to continue or end. For example, when the reading data becomes unnecessary, when the user inputs the event data 21, “end” is added to the status of the transmission data 50 shown in FIG. 3 as the attribute of the process data. In this case, the process ends. On the other hand, when the status of the transmission data 50 is “continuation”, “continuation” is added to the attribute of the corresponding process data, and S2 to S6 are repeated.

Next, the speech data created by the speech data creation means 8 is converted into speech data by the speech conversion means 9. Then, the audio data is output from the audio output means 10 to the outside with reference to the audio output database F2.

As described above, according to the first embodiment of the present invention, process data in response to a request from a user is taken in, and transmission of data evaluated based on professional data and conditions for changing the state of a plant is performed. The period is determined. When data is input to the audio output device in the determined transmission cycle, read-out data is created, and the read-out data is controlled at a predetermined timing and output to the outside. As a result, read-out data based on the process data corresponding to the plant change state is created, and the read-out data is controlled and output at a timing that is easy for the user to understand. Therefore,
Information necessary for the user can be transmitted by voice at an appropriate timing.

Next, a second embodiment of the present invention will be described with reference to FIG.

In the data evaluation means 5 shown in FIG.
As shown in FIG. 8, the process data change rate is compared with a predetermined change rate reference value (S10). The data transmission cycle is determined based on the comparison result (S11). For example, when the data changes as shown in FIG. 9, the process data change rate is obtained by using the following equation (1).

Process data change rate = K {X (t) −X (t−1)} (1) X: Data value K: Normalized constant t: Time

At this time, it is determined whether or not the process data change rate is within the change rate reference value. If the data 54a changes as shown in the chart 54 of FIG. In the area B of FIG. 9, the transmission cycle is shortened to make the reading cycle faster. Further, in the areas A and C in FIG. 9 where the process data change rate is gradual with a change equal to or less than the change rate reference value, a long transmission cycle is determined so as to read out at intervals. L3 shown in FIG. 9 is a data reference value. This suppresses unnecessary output of sound when the change is small.

Note that a plurality of change rate reference values may be set, and the transmission cycle may be three or more steps. Further, the change rate reference value may be set uniformly or may be set for each process data.

Next, in the processing shown in FIG. 8, the priority at the time of reading out the process data is changed according to the evaluation result transmitted in a short cycle (S13). Next, the audio output device 10
If the elapsed time after transmission, which is the time difference between the previous data transmission time to 1 and the current time, is greater than the transmission cycle, transmission data is created (S14, S15). If smaller, the process returns to step 10 without performing data transmission (S14).

In the process of S 16, “end” or “continuation”, which is the status of the transmission data 50, is referred to based on the user event data 21. If the status is “end” according to the reference result, the process ends. If the status is “continue”, the process returns to the process 10 and is repeated.

When setting for each process data,
The present invention can also be implemented by comparing the deviation between the process data and the data set value.

That is, in the plant, from the viewpoints of maintaining the function of the plant and protecting the equipment, a set value as a reference for generating an alarm and a set value as a reference for automatic operation of the equipment are determined for each process data. Here, the deviation between the set value and the process data value is obtained, and when it is determined that the deviation is within the reference value and close to the set value, the data transmission cycle is shortened to shorten the reading interval.

Further, it is also possible to carry out the reference setting based on the change characteristics of the data. Process data has different change speeds and safety likelihoods depending on physical characteristics, operation characteristics of devices that are change factors, how to take units, and the like. If a uniform reference value is set, the effect may not be obtained. In such a case, it is preferable to control the data transmission cycle by setting a reference value in accordance with the change characteristics of each process data.

As described above, according to the second embodiment, the process data is evaluated in accordance with the rate of change of the process data and the reference value of the rate of change or each deviation between the process data value and the set value. The transmission cycle is controlled. Thus, when the plant is in a changing state, that is, when the plant is suddenly changing, the data transmission cycle is shortened in order to quickly read out the change value of the corresponding process data, while when the plant is stable, the data transmission cycle is changed. Can be longer. Therefore, the data required by the user is accurately read out according to the plant state.

Next, a third embodiment of the present invention will be described with reference to FIG.

First, the data evaluation means 5 compares the current value of the process data with a predetermined target value as shown in FIG. 10 (S21). Based on the comparison result, a data transmission cycle is determined according to the magnitude of the deviation (S23).

Here, when the data transmission cycle is short, the priority is changed to be higher (S24, S2).
5). Next, if the post-transmission time based on the time at which the data was transmitted to the audio output device 101 and the current time is longer than the transmission cycle, transmission data is created (S26, S2).
7). In this case, if the elapsed time after transmission is smaller than the transmission cycle, the process returns to step S21 without performing data transmission (S2).
6). On the other hand, when the process data value reaches the target value, transmission data is created as event data (S2).
2, S29).

As described above, according to the third embodiment, in the operation at the time of plant operation or maintenance, it may be desired to perform an operation when the process data reaches a certain value. Since the target value at this time differs for each operation, it must be input each time. In order to respond to this request, the user is allowed to input a target value, the same processing as the deviation comparison with the data set value is performed, and the data transmission cycle is controlled.

That is, a target value for the process data 55a is set as shown in a chart 55 in FIG.
In a region 55b surrounded by a square in which the data value approaches the target, the user needs to prepare for the operation to be performed when the target is reached, and therefore pays attention to the change in the process data.
In such a situation, the number of times of reading data is increased so that the timing is not lost.

As described above, according to the third embodiment, when the process data is far from the target value, the trouble of outputting unnecessary read-out data is reduced. Further, as the process data approaches the target value, the data transmission cycle is shortened, and the necessary data is notified to the user by voice in a detailed manner, so that the work efficiency can be improved.

Next, a fourth embodiment of the present invention will be described.

The data evaluation means 5 according to the fourth embodiment of the present invention evaluates plant event data separately from the evaluation of process data.

In the fourth embodiment, it is evaluated whether the event data such as the arrival of the set value related to the process data or the operation of the device has changed from “OFF → ON” or “ON → OFF”. Is established, the transmission data is created. Depending on the event, only the occurrence of the event may be notified, and the disappearance of the event may not be notified. This selection is set for each event or from the establishment status of the linked event (for example, the occurrence status of “low water level” and “low water level”).

As described above, according to the fourth embodiment, in the case of an important event by evaluating the event data, the user is quickly and reliably notified of the read-out data as a short-period transmission cycle by repeating the operation early. On the other hand, in the case of an unimportant event, data to be read out as a long transmission cycle is read out at long intervals.

Next, a fifth embodiment of the present invention will be described with reference to FIG.

In the process of FIG. 12, event data is additionally written into the event data file F4 sequentially (S
31). In reading data from the event data file F4, first, data with the highest priority is selected from the file (S32 to S34).

Here, the time from the transmission of the event data to the reading of the event data is managed, the event data that has passed for a predetermined time after the transmission is deleted from the event data file F4, and only the new data is read out (S35 to S35). S37). This prevents reading out of event data at an inappropriate timing while waiting for a turn.

It should be noted that, as shown in FIG.
In the same processing as in step 35, if the priority of the event data is high even if the elapsed time after writing has passed the specified time, additional data can be added to create read-out data (S35, S39, S40). . For example, for the data of "event data: pump trip, elapsed time: 10 seconds", data such as "10 seconds elapsed after pump trip" is created.

As described above, according to the fifth embodiment, when a plurality of pieces of readout data compete with each other, reading out is stopped when a waiting time for reading out has reached a predetermined time, so reading of unnecessary meaningless timing is avoided. Is done. In addition, data having a high priority to some extent is read out with a delay time added even if the reading out is slightly delayed.

Next, a sixth embodiment of the present invention will be described with reference to FIG.

First, data to be read is selected (S41, S42). In this case, when data is written to the file, the priority of the process data is compared with the priority of the event data, and the process data or the event data having the higher priority is selected (S43). Here, if the event data is the highest priority, the event data in the event data file F4 is directly converted into a character string of audio data (S43, S44). Then, after reading the data and recording the reading time, the corresponding event data is deleted from the event data file F4 (S45 to S47).

On the other hand, when the process data is selected,
First, at the time of the first reading, the data number, abbreviation, and unit are selected from the initial data file F6 (S4).
8). In this case, the name number is converted into the name of the process data used when the user inputs data (S48, S48).
49). At the time of data reading, these data are combined with the numerical data written in the process data and output. This combination depends on the data transmission cycle, and as the cycle becomes shorter, a character string in the following order is generated and converted to voice (S50 to S52).

1) Name + Numerical Data + Unit (Example: Reactor Water Level 900mm) 2) Abbreviation + Numerical Data + Unit (Example: Water Level 900mm) 3) Numerical Data + Unit (Example: 900mm) 4) Numerical Data (Example) : 900)

After reading the data, the reading time is recorded, and the data in the process data file F3 is deleted (S47). Note that a mechanism for converting character string data into speech uses a character string reading method conventionally used.

As described above, according to the sixth embodiment, when a plurality of data are on standby, the read-aloud data is output to the outside in descending order of priority. In this case, when the transmission period to be read out is short, the character string is output as a short character string, and when the transmission period is long, the character string is output as a long character string. Therefore, a large amount of read-out data is output within a limited time, and the waiting time can be reduced, which is more efficient.

Next, a seventh embodiment of the present invention will be described with reference to FIG.

In the seventh embodiment, priority control means is provided for dealing with a situation where a large amount of event data is generated and process data is skipped for a certain period of time.

More specifically, as shown in FIG. 15, when there is process data in the process data file F3, the waiting time of the process data that cannot be read out is calculated (S51, S52). At this time, when the calculated waiting time of the process data is equal to or less than the specified time, the above processing is repeatedly performed (S51 to S54). In other words, if the reading of the process data has not yet passed the specified time even if a large number of event data have occurred, the reading of the event data is prioritized.

Next, when the reading wait time of the process data exceeds the specified time in the processing S53, the priority of the target process data is changed to a higher priority (S55). In particular,
ΔP (priority)> Pm (maximum event priority). Thus, when the process data is read out during the reading of the event data, the time after the priority change in step S55 is calculated, and it is determined whether or not the elapsed time after the priority change is within the specified range (S56 to S58). . If it is determined in the processing S58 that the process data is within the specified time, the priority of the process data is restored (S59).

If the process data has not been read aloud this time in step S56, and if the number of continuous readings of the process data is equal to or greater than the specified value, the process proceeds to steps S57 and S58. On the other hand, if the value is equal to or smaller than the specified value, the process of restoring the priority of the process data is performed, and the process proceeds to S54 (S60 to S61, S59). In other words, if the process data is read out even once with a high priority, the priority of the process data is returned to the original level so that reading out of other process data or event data is not hindered. On the other hand, when it is determined that the process data is read out in S54, the waiting time of the process data is cleared (S62).

As described above, when the process data is skipped by the event data for a certain period of time, the priority of the process data is changed to be higher, and the reading of the process data is interrupted during the reading of the event data. For this reason, the priority of the process data left unread for a certain period of time is increased by ΔP as follows.

(ΔP)> Pm Pm: maximum priority of event data

When a certain period of time has elapsed after the priority change, or when the process data is read out one or more times, the priority of the higher process data is restored.

As described above, according to the seventh embodiment, when the reading wait state of the process data is long, the priority can be increased to interrupt the reading of the event data. can do.

Next, an eighth embodiment of the present invention will be described with reference to FIG.

The eighth embodiment is provided with a priority control means corresponding to a case where there are a plurality of process data to be read.

In FIG. 16, the priority control means executes the following processing.

First, when the data is read out, it is determined whether or not the change is due to a change in the priority taken in next (S65). In this determination, the priority is changed, and if the data is longer than the specified time, the priority of the data is returned to the original (S66 to S68).

On the other hand, in the case of data whose priority has not been changed, or in the case where it is shorter than the specified time in the processing of S67,
It is determined whether the previous read-out data is different target data (S67). In this determination, when the same as the previous reading data, the reading priority change elapsed time is calculated,
If the calculated elapsed time is equal to or shorter than the specified time, the process directly waits for data reading (S70, S71).

In step S69, if the data is different from the previous reading data, it is determined whether or not the reading interval is a short period. If the reading period is short, the number of continuous changes of the reading data is counted and the continuous change is defined. If the number is equal to or more than the number of times, the priority of the read-out data is changed (S73 to S7
6). Thus, when a plurality of data need to be read out, the same data is read out continuously and the next data is read out sequentially. Therefore, a situation in which different data is read aloud is prevented.

As described above, when a plurality of pieces of process data read out conflict with each other, there are a case where another data is confirmed during the reading of data and a case where a plurality of process data are confirmed simultaneously. In the former, the first data reading is temporarily interrupted to read another data, and in the latter, a plurality of data are read at the same time.

In order to cope with such a situation, process data files are prepared by the number of process data, and the data of the name number 1 is written in the file 1 and the data of the name number 2 is written in the file 2. Here, name number 1
When reading out the data of name number 2 by temporarily suspending the reading of the data of name 2, the file of name number 1 is excluded from the search target, and only the file of name number 2 is searched. It should be noted that the data transmission of the data of the name No. 1 is continuously performed so that the latest data is read at the time of resumption.

Next, when reading out a plurality of process data at the same time, it is necessary to prevent the data from being read out alternately and complicate the voice, or to prevent the reading of only one data due to the difference in priority. Also,
The importance of the process data differs depending on the change status of the process data. Therefore, the priority of each process data is controlled by the following procedure so that each process data can be read out at an appropriate data selection and reading interval.

1. The priority of the read process data is increased by Δp. 2. The priority of the process data left unread for a certain period of time is increased by ΔP. (ΔP> Δp, ΔP> P
(m Pm: maximum priority of process data to be read out) The priority of the process data is controlled in multiple stages according to the magnitude of the data change rate. 4. If a certain time has elapsed after the priority change, or if another process data is read out, the priority of the process data that has been increased is returned to the original.

The above 2. Can be used for the priority control of FIG. 1. Is performed using the processing of FIG. In addition, 3. Can be performed by selecting the priority in accordance with the transmission cycle when evaluating the change rate of the process data.

As described above, according to the eighth embodiment, since specific data is read aloud to some extent, different data are read aloud instead of each other, so that it is possible to avoid a situation where it is difficult for each user to understand the data. You. Therefore, the user can easily acquire the data required by the user by voice.

Next, a ninth embodiment of the present invention will be described with reference to FIGS.

In a central control room or on-site work of a plant, attention is often given by voice and detailed information is confirmed on a screen. In order to cope with such a case, efficient information provision is performed by linking audio output and screen output.

Here, when confirming a plurality of process data, the reading of the process data is controlled by the above-described method. In a situation where the screen output can be used, information is provided by utilizing the following advantages of the screen output.

1. The data update cycle can be shortened. 2. Multiple data can be displayed at the same time. 3. History can be displayed.

For example, as shown in FIG. 17, event data related to all of the selected process data is displayed on the screen. In FIG. 17, the reactor water level “740 m” is displayed in the process data display area 56 a on the display screen 56.
m "and the pump flow rate" 2100 "T / N are displayed, and the reactor water level" L-
4 or less ”is displayed, and“ water level 740
mm ”.

If there is room for data transmission and display capability as in the main control room, the process data may be displayed in a graphical representation such as a trend. In addition, the related information is displayed on the screen as shown in FIG. 18 by using the above-mentioned voice notification at the time of occurrence of the plant event or reaching the target value as a trigger. In the example of FIG. 18, a system diagram 56c is displayed on the right side as related information corresponding to FIG.

As described above, according to the ninth embodiment, since the voice output and the related data are displayed, necessary information is transmitted to the user. Therefore, inconvenience such as viewing the display of the related data at another timing is eliminated.
