[0023]
BEST MODE FOR CARRYING OUT THE INVENTION
A configuration example of an embodiment of the training device according to the present invention will be described with reference to FIG. The device basic unit 20 includes a scenario data storage unit 1, a reliability information setting unit 2, a training data storage unit 3, a data display unit 4, a display condition setting unit 5, a peak value determination unit 6, a display data storage unit 7, and a display. It has a data distribution unit 8 and a password registration unit 10.
[0024]
The display data distribution unit 8 is connected to the router 22, and the router 22 is connected to the terminal device 9 via a LAN or a communication network such as a network or the Internet. Functions of the display data distribution unit 8, the router 22, the terminal device 9, and the like will be described later.
[0025]
The scenario data storage unit 1 stores scenario data, and the scenario data is, for example, time-series data indicating a plant behavior created using a plant analysis code or the like. The reliability information setting unit 2 reads the scenario data, sets information indicating the reliability index of the data value according to a user's request, sets the data as training data, and stores the training data in the training data storage unit 3.
[0026]
Examples of the configuration of the scenario data and the training data are shown in FIGS. 2 and 3, respectively.
The information indicating the reliability index is the reliability information shown in FIG. 3, and is, for example, 0 (zero) in a normal state, 1 in a case where the value deviates from the upper and lower limit values, and a case in which measurement cannot be performed due to a failure of the sensor itself. Is set for the data value in the form of 2.
[0027]
The user selects, for example, on the interactive screen shown in FIG. When the setting is selected by the upper and lower limit values, as shown in FIG. 4B, the upper and lower limit values are input in the table for each parameter. If each parameter exceeds the input upper / lower limit value, the reliability information of the data value is set to 1 (deviation from upper / lower limit) and this is regarded as “bad”, otherwise, 0 (normal) ).
[0028]
When setting by a period, as shown in FIG. 4C, a start time series number and an end time series number are input in a table for each parameter. In the range between the input start time series number and end time series number, the reliability information of the data value is set to 2 (bad), and otherwise to 0 (normal).
When data conversion or the like is required between the scenario data and the training data, the trust information setting unit 2 converts the data into data suitable for display.
[0029]
In general, analysis codes output by calculation even values that cannot be measured in an actual plant. On the other hand, a situation in which a data value cannot be acquired due to equipment failure or the like cannot be simulated even in an event where equipment is not operating normally in a plant emergency. For this reason, even if a disaster prevention drill is performed using the analysis data, it may be different from the actual situation. According to the above embodiment, by adding the reliability information of the data value to the scenario data created by the analysis code, it becomes close to the process value obtained from the actual plant, and it is possible to perform more practical training. It becomes possible.
[0030]
Next, functions of the display condition setting unit 5 and the like of the embodiment of the training device shown in FIG. 1 will be described. The data display unit 4 reads the contents of the training data from the training data storage unit 3 in accordance with a command from the display condition setting unit 5 and performs display while periodically updating the data. The data display unit 4 has screens necessary for grasping the state of several types of plants. FIG. 5A is an example of a screen for selecting and displaying a main parameter of a plant as a trend graph, and FIG. 5B is an example of a screen for displaying a main parameter of a plant as a summary.
The user sets display conditions on, for example, the interactive screen shown in FIG. 6, and the data display unit 4 displays data according to the set conditions.
[0031]
First, the time condition of the training data is set on the data time condition setting screen shown in FIG. Here, the data head time is the time of the first time-series data of the training data, and the unit time indicates the data interval between the first and second data. In the example shown in FIG. 6A, the unit time is 60 seconds at the data head time 2001/10/20 00:00:00. In this case, the second data of the training data is interpreted as 2001/10/20: 00: 01: 00. The data head time is a default, and the internal clock time of the apparatus is set in advance.
[0032]
Next, a display method is selected for the data time to be displayed on the screen. Select whether to display the internal clock as it is or to display the data time according to the time set in the data time condition setting of the training data.
[0033]
Next, the specification of the data reading condition will be described with reference to FIG. Here, the range of time for setting the condition is set by the registration start time series number and the registration end time series number, and the processing method is designated from among fast-forwarding, thinning-out, skipping reading, and stopping reading.
[0034]
In the case of fast rotation, if the update speed during that time is selected, for example, from 1 to 10 times speed and the registration button is pressed (clicked), the set conditions are registered. In the selection of the double speed, the selection range is limited in consideration of the load of updating the display of the screen so that, for example, the maximum double speed is 5 seconds or more in relation to the unit time set earlier.
[0035]
In the case of thinning, each parameter is read by skipping data in the time series direction by a designated numerical value. For example, when 5 is designated, data for every five data is read such as 0, 5, 10,. If skipping is specified, data between the specified time-series numbers is skipped. When the reading stop is designated, the reading is stopped with the data designated as the registration start time series number as the last. The time is set as 1 × speed between time series numbers for which the user has not specified anything.
[0036]
The content set by designating the data reading condition can be stored in the display condition setting unit 5 for a fixed number, and the setting content can be reused from the next time. The setting of the data reading condition can be set online while the data is being read. The current time series number is displayed on the dialogue screen so that you can grasp the progress when setting online while reading data.
[0037]
Next, the data reading start request will be described with reference to FIG. The start of data reading can be selected either immediately from the request time or by specifying the reading start time as a timer.
The display condition setting unit 5 calculates an update cycle from the display conditions, and transfers the update cycle to the data display unit 4 together with the set display conditions.
[0038]
FIG. 7 shows an example of information passed to the data display unit 4. First, a data head time and a display time are specified. The display time is adjusted to the internal clock in the case of 1, for example, and to the data time in the case of 2. The read start time is passed in the form of a time when the request is executed, even if “immediately” is specified. There are a start time series number, an end time series number, a request type, a data read interval, and an update cycle. For example, when the request type is 1, the request is advanced, when the request type is 2, the skipping is performed, the reading is skipped at -1, and the reading is stopped at 99.
[0039]
The update cycle is:
Update cycle = unit time / double speed
And in the case of thinning,
Update cycle = unit time
It becomes.
The data reading interval specifies how often data is read. The data reading interval is set to 1 for fast-turning, and to the thinning-out setting value for thinning-out.
[0040]
The data display unit 4 periodically reads and displays the data in the training data storage unit 3 according to the conditions at an update cycle time. This detailed procedure will be described below with reference to FIG.
[0041]
In step S1, the display conditions input by the user passed from the display condition setting unit 5 are read, and in step S2, the data reading start time is determined. If the data reading start time is zero, the process immediately proceeds to step S5 to read the training data.
[0042]
If the data reading start time is other than zero in step S2, that is, if the data reading start time is specified as a future time, the time is periodically checked in step S3, and the time is later than the specified time. At this time, that is, when the internal time is greater than the data reading start time, the process proceeds to step S5, where the training data is read from the training data storage unit 3.
[0043]
After reading the training data, display conditions are read in step S6. Here, when the training data is completed, the process proceeds from step S7 to the end. If the training data has not been completed, a request is made by comparing the time series number of the data with the start time series number and the end time series number of the display condition data passed from the display condition setting unit 5 in steps S8 and S9. Determine the type.
[0044]
If the request type is "stop" in step S9, the process immediately ends. If the request type is "skip" in step S9, an operation of advancing the pointer to the designated time series number is performed in step S10, and thereafter, the process returns to step S5.
[0045]
If the request type is any of “thinning out”, “early turn”, and “1 × speed” in step S9, the screen is displayed in step S11. After that, the read cycle time is waited for in step S12, then the pointer is advanced in step S13, and thereafter, the process returns to step S5.
[0046]
The contents of the screen display are based on the contents set by the display condition setting unit 5, and the data time is displayed on the screen. When the data time is adjusted to the internal time, the actual time of the internal clock is displayed regardless of whether the data is skipped or turned forward. If you want to fit the data, fast turn, thin out,
Start time + unit time × serial number
Is represented by
[0047]
As a method of thinning out data, in addition to thinning out at a fixed interval for each designated number, there is also a method of using a peak value. The peak value determination unit 6 determines the peak value in this case.
[0048]
As a method of specifying the peak value, for example, a method of picking up the maximum and minimum values within a period for each parameter, and focusing on one of the parameters, indicating the maximum and minimum values within the range of the parameter. There is a method of reading all parameters according to the time series number. The peak value is determined by selecting one of the methods.
[0049]
Here, the maximum and minimum extraction methods will be described. When the thinning interval S is specified, the peak value determining unit extracts the maximum and the minimum from the S data, and the thinning rate becomes S / 2. In order to determine the maximum and minimum peak values without changing the thinning rate, the data extraction determines the maximum value and the minimum value for S × 2 data. For example, if the set value of the thinning is 5, the maximum and minimum extractions are determined in ten data periods. When the same value overlaps with a plurality of time series numbers, for example, the smaller one of the time series numbers is selected.
[0050]
An example of the processing procedure of the maximum / minimum determination method will be further described with reference to the flowchart in FIG. In step S31, a thinning interval S is set, and in step S32, training data is read. Next, the count value i is set to 1 in step S33, and the value of n + i is set to MAX and MIN in step S34. Here, n is a time series number.
[0051]
Next, i is increased by 1 in step S35, and the (n + i) th training data is read in step S36. In step S37, the value of MAX is compared with the value of the (n + i) th training data. If the former is smaller, in step S38, MAX is replaced with the (n + i) th training data, and MAXn is set to n. Next, in step S39, MIX is compared with the value of the (n + i) th training data. If the former is larger, in step S40, MIX is replaced with the value of the (n + i) th training data, and MIXn is set to n.
[0052]
Next, in step S41, i is compared with S × 2. If the former is smaller, the process returns to step S35. Otherwise, the process proceeds to step S42 to wait for the next start command.
When calculating the maximum and minimum values for all parameters, the maximum and minimum determination processing is repeated for each parameter.
[0053]
Next, a method of focusing on one of the parameters and reading all the parameters in accordance with the time series numbers indicating the maximum and minimum values within the parameter range will be described. The peak value judging unit 6 reads S (thinning-out interval) × 2 pieces of data to be read next from the training data storage unit 3 for the designated parameter, and determines a time-series number having an upper limit and a lower limit peak. Judge and notify the data display unit 4. The data display unit 4 extracts and displays all parameters according to the notified time series number.
[0054]
For example, the procedure shown in FIG. 9 is performed for one designated parameter, and the time series numbers of MAXn and MINn thus obtained are passed to the data display unit 4, and the data display unit 4 sends MAXn and MINn from the training data storage unit 3. The data at the position of is read for all parameters.
The data read and displayed by the data display unit 4 can be recorded in the data storage unit 7 and reused.
[0055]
In the display condition setting section 5, for example, a registration start time and a registration end time can be designated on a trend graph screen as shown in FIG. 10 to set a period. When the “designate by graph” button is pressed (clicked) on the data reading method designation dialogue screen of FIG. 6, the screen (window) of FIG. 10 is displayed in an overlapping manner. When the cursor of the graph is moved to a place to be registered and the start number determination or end number determination button is pressed, the period is set to the registration start time series number and the registration end time series number in FIG.
[0056]
As described above, according to this embodiment, by setting the data display speed arbitrarily in a plurality of arbitrary periods, without missing data, in accordance with the plant behavior change, a portion having a large behavior change is Since a portion having a low speed and a small change can be displayed at a high speed, even when the training time is short, the disaster prevention training can be efficiently and effectively performed.
[0057]
In addition, since the display speed of training data can be changed arbitrarily online according to the situation at the place, not only can it respond flexibly to sudden changes during training, but also training can be performed at the preparation stage before training. When confirming the display of data for use, it is also possible to efficiently confirm the preparation stage in advance while displaying and evolving a portion to be noted at a low speed and a portion with a gentle behavior at a high speed.
[0058]
Furthermore, by setting the data thinning interval arbitrarily in a plurality of arbitrary periods, the data can be thinned or skipped according to the behavior of the plant rather than uniformly, so that the unit time of the training data is, for example, 1 second. Even in the case where the data is short, by thinning out the data, it is possible to smoothly update the screen without increasing the display load.
[0059]
In addition, by thinning out according to the peak value of a specific parameter which is a point of the plant event, it is possible to thin out the data without impairing the characteristics of the event. In addition, by changing the data thinning interval online, it is possible not only to respond to sudden changes in the time of the disaster prevention drill on the fly, but also to adjust the thinning interval while looking at the display screen. The stage can be confirmed efficiently.
[0060]
Furthermore, by setting while observing the behavior of the plant in the graph, it is possible to easily perform settings such as quick rotation and thinning in accordance with changes in the behavior of the plant. Further, when thinning out data, the upper limit value and the lower limit value are extracted and thinned at twice the thinning interval, so that both the upper limit value and the lower limit value can be changed without changing the thinning rate of the entire data. Data can be decimated in consideration of.
[0061]
Also, when thinning out data, paying attention to a specific parameter that matches the characteristics of the event, extracting and thinning out the data in accordance with the time position indicating the upper limit value and the lower limit value of the parameter, the same The data can be thinned out while reflecting the characteristics of the event without impairing the mutual relationship between the parameters at the time.
[0062]
Further, the progress of the reading of the scenario data is concretely displayed on an interactive screen for setting display conditions by number, position, etc., so that it is easy to understand when changing the display conditions online.
[0063]
Next, functions of the display data distribution unit 8, the password registration unit 10, the router 22, the communication line 24, the terminal device 9, and the like shown in FIG. 1 will be described.
The display data distribution unit 8 distributes the screen displayed on the data display unit 4 to the web, and distributes the screen by a terminal device 9 having a browser function connected via a communication line 24 such as a LAN, a public line, or the Internet. The user can refer to the displayed screen and set display conditions.
[0064]
In order to connect the terminal device 9, the terminal device 9 that can be connected is limited in advance by, for example, registering the telephone number of the other party in the router 22 or the like, and the password is registered by the password registration unit 10. It is necessary to register in advance.
[0065]
Furthermore, in order to set display conditions from the terminal device 9, it is necessary to register a dedicated password, and when the display condition setting dialogue screen is opened from a menu or the like, the user ID and password must be input. Urge. The user is identified by the password, and the setting operation of the display condition is not permitted for the user whose password does not match. The registration of the password is provided with an interactive function for registration so that the deletion can be easily changed. In addition, a period is set for the password so that a password used a certain number of times in the past, for example, the past 1000 times cannot be registered.
[0066]
In this way, by displaying the data on the terminal device 9 at a remote location, the same data can be displayed using the existing line infrastructure from anywhere in the training site, and the progress of the plant behavior can be displayed at a remote location. , And effective training can be performed. In addition, since the display setting can be performed at a remote location, it is possible to use the functions of the present apparatus in various places without moving the apparatus basic unit 20 to the use place every time of training. In addition, by providing the user with the use of the training device function, the user can use the function of the present device with only the terminal device 9 without owning the device basic unit 20.
[0067]

It is possible to do.
[0068]
According to the fourth to eleventh aspects of the present invention, by arbitrarily setting the data display speed, for example, in accordance with a change in plant behavior, a portion having a large change in behavior is displayed at a low speed, and a portion having a small change in speed is displayed at a high speed. Even if the training time is short, disaster prevention training can be performed efficiently and effectively.
