Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for displaying a trend of time-varying data on various graphs,
Especially the display method is the characteristics of the input data (value, variation, etc.)
Or, based on the display state of the display device, a plurality of graph display methods are displayed in parallel, and the display is dynamically changed,
The present invention relates to a time change data display device.

[0002]

2. Description of the Related Art The display means of a conventional time-varying data display device is limited to a specific display system as described below, and has a general-purpose graph display means adaptable to various uses. There wasn't.

For example, the display device described in Japanese Patent Laid-Open No. 2-176698 uses a display system in which the graph display is enlarged or reduced by partially changing the display magnification of the already-displayed graph.

Further, in the trend graph display device described in Japanese Patent Publication No. 62-26469, a graph is displayed when the graph display reaches the end of the graph display area in order to always display the trend of the data value near the current time. A display method is adopted in which the graph display from the display area start point to the intermediate point is erased and the graph display from the intermediate point to the end point is slid to the graph display area from the graph start point to the intermediate point.

[0005]

The view of the data that changes with time changes depending on the passage of time.
Regarding the latest data, it is necessary to grasp the transition of the data value in detail, and regarding the old data in the past, it is often necessary to grasp only the rough tendency of the data value change. However, there may be cases where it is desired to grasp the change status in detail for the data section that has undergone a characteristic change even with respect to old data in the past.

On the other hand, since the above-mentioned conventional technique uses a single graph display system for each data type, it is impossible to view the same data differently at the same time. In addition, since the past data display is erased with the passage of time, there is a problem that the tendency of data change over a long period of time cannot be grasped.

Further, even if it has a plurality of display formats,
Since it is necessary to switch the display format and display again to display again according to the purpose, visibility and operability are degraded.

An object of the present invention is to provide a display device for displaying time-varying data in a suitable display format for each time section when the way of viewing time-varying data changes with the passage of time. To do. Further, by compressing and displaying a large amount of data for a long time within a limited display area, the visibility of the data is improved and the characteristic tendency of the data change is easily grasped.

[0009]

[Means for Solving the Problems] The above-mentioned object is to display data that changes with time in the form of a graph, in which time-varying data is divided into time intervals and graphs that match the purpose are displayed in juxtaposition. Display / editing means, realizing the change of each graph, the amount of data processed up to that point, the usage rate of the display area displaying the data group,
This is achieved by the display format definition data storage means for storing the conditions and the graph display change detection means, which uses the elapsed time since the first time change data is generated, the change amount of the value of the time change data, or the value itself. . Further, in displaying a large amount of data in a limited display area, it is achieved by collectively displaying a plurality of data groups and representing them by their maximum value, minimum value, and average value.

[0010]

Operation: Display format definition means for defining the display format of a graph and under what circumstances the display format is used, and display format definition data storage means for storing the defined contents. Graph display change detection means for detecting whether or not the condition defined by the user is satisfied in the process of sequentially processing the time change data, graph display edit result storage means for storing past display results, and defined display format Based on the above, the graph display editing means for re-editing and outputting the time change data in the display format including the past time change data can be realized.

(A) The graph display edit table is a table for storing direct data (X, Y coordinates, etc.) for drawing a graph. The graph display edit table is created based on the graph display content table and is updated each time the time change data is input.

A display number 601 is a unit of processing in the X-axis direction (hereinafter referred to as an entry), and an empty pointer 602 indicates that this entry has not been processed, and the graph type to be displayed for this time change data. Shows.

The graph type pointer 603 points to the corresponding change group 412 of the graph display content table and the corresponding format 407 therein.

The coordinate 604 stores an X coordinate value and a Y coordinate value to be plotted as data values. Where Y
2 and Y3 are used together with Y when the data is compressed and displayed, and Y is the maximum value, Y2 is the minimum value, and Y3 is the y coordinate of the average value.

The data table pointer 605 indicates a data section used for displaying the corresponding graph, and stores the data number of the time-series data storage table which stores the time-varying data that is sequentially input.

In this table, the required number is calculated and secured from the graph display content table which is determined to be applied. The X coordinate of the graph type pointer 603 and the coordinate 604 is also created at this time.

Next, the operation of this embodiment will be described with reference to FIG.

FIG. 7 shows the processing for one time-varying data. First, the data input processing 701
Then, the time change data from the outside obtained from the data input means 102 is fetched.

In the graph display change condition determination 702, the graph display status so far, that is, the number of displayed data, the elapsed time, the time change data value processed last time, the display position so far on the graph display area, and the current input. The graph change condition table is searched based on the obtained data. All the defined change conditions are searched, and if there is a condition term that matches the change conditions, the display content storage pointer that defines the details of the graph display is taken out, and the next step is the graph display edit table update 704. Send to.

In the graph display edit table update 704,
Reorganize the graph display edit table based on the graph display content table. Reorganization is performed by first determining the required number of groups (graphs) according to the display section defined in each format in the change group of the graph display content table indicated by the pointer sent by the graph display change condition determination and the X scale in the parameter. Calculate one line of the display edit table). The required number of sets for each format can be obtained by (display section / X scale) +1, and this is calculated for the number of display formats, and these are added to the required number of sets for the graph display edit table. Secure the graph display edit table for this number of groups,
Next, the term of the graph type pointer and the X coordinate are stored for each set. The graph display edit table created in this way is sent to the next redisplayed graph 705 of the already displayed part.

In the already-displayed part graph re-editing 705, when there is already input (past) time change data, a graph display editing table is created for these data.
The details of this processing are shown in FIG.

First, in the initialization 801 of the control pointer, a pointer (hereinafter dptr) for sequentially fetching data from the time series data storage table in which existing data is stored.
Is set to the value of the display start data in the graph display content table, and the pointer (hereinafter gptr) indicating the entry to be processed in the graph display edit table is set to 1.

In the next data acquisition 802, the data value of the data number of dptr is acquired from the time series data storage table.

In the display information fetching 803, the graph type pointer of the value whose display number is gptr is referenced from the graph display editing table, and the compression ratio is calculated from the graph display content table.
Capture Y scale.

If the compression rate is 1, the Y coordinate calculation 805
Calculate the Y coordinate. That is, since there is no data compression, Y that should be displayed based on the data value acquired in 802.
Coordinates are calculated by data value x Y scale. The obtained y coordinate is stored in the coordinate Y in the graph display edit table. If there is data compression, it is determined in block 806 whether this data is the first data in the data compression group, and if it is the first data, in block 807, the value of this time series storage table pointer dptr is displayed as a graph. Store in the data table pointer (start) in the edit table. If it is the last data, it is stored in the in-table data table pointer (end) in block 809. And block 810
And the maximum, minimum, and
Calculates the average and coordinates Y, Y in the graph display edit table
1 and Y2, respectively.

In block 811, dptr and gptr are respectively updated by +1 and the above-described processing is repeated for all existing data, that is, for the data stored in the time series data storage table. In block 706 of FIG. 7, the time-varying data obtained this time are subjected to the processing of 803 to 810, and the time-varying data obtained this time is stored in the time-series data storage table.

In the graph display processing of block 707, a graph is drawn based on the graph type in the graph display edit table and the value of each coordinate.

Next, FIG. 9C shows an embodiment in which the time-varying data display device displays the time-varying data over a long period of time by compressing past data and displaying recent data changes in detail by the time-varying data display device. Show. This is an effect that makes it easy to predict future data changes by displaying the past data changes in a compressed manner by grasping the trend of data value changes so far and displaying the behavior of recent data changes in detail. It is suitable for showing the progress of learning of neural networks and the automatic adjustment of membership functions in fuzzy inference systems, and the changes at start-up, stop-time and state changes of plant data.

An example of the graph display in this case will be described based on concrete data. First, the graph display area is shown in FIG.
As shown in (a), 30 mm in Y-axis direction and 100 mm in X-axis direction
Suppose The data display in the X direction is displayed at 5 mm intervals, and 20 time change data can be displayed in the display area. At first, the data is not compressed and displayed as a line graph as shown in FIG. When this display reaches the rightmost end of the graph area, the data so far is compressed and displayed in a range 901 which is half the display area, and the remaining area 902 is filled with the data. The line is displayed without compression. Then, when the data display reaches the rightmost end again, the data up to that point is halved.
The compression to the range 901 is repeated.

The graph display change condition table and the graph display content table for realizing the above-mentioned graph display are
10 (a) and 10 (b). Further, it is assumed that the data value input as the time change data is as shown in FIG. Further, the range of these data values is assumed to be 0.0 to 10.0.

When a condition relating to time such as elapsed time is used as the condition for changing the graph display, the generation time of the time change data is necessary, but this is omitted here.

Two conditions are required in the graph display change condition table for realizing the above-described graph display. First, one is the condition 1 when processing the first data.
The content displayed in the graph at this time is the format 1 (100) of the change group 1 indicating a line graph without data compression.
3). The other is the condition 1002 when the graph display reaches the rightmost end of the graph display area. In the graph display content table at this time, half of the display area is change group 2 showing the data compression display by the candlestick.
Format 1 (1004) of the change group 2 of which the remaining 1/2 indicates a line graph display without data compression
005).

The compression ratio in the candlestick display is 1/2
Since 10 display items can be displayed in the display area of
It is a value obtained by dividing the number of input data so far by 10.

When the first time change data is input, it matches the graph display change condition 1001.
In the graph display edit table shown in 1, the graph type pointer and the X coordinate are created. Since the number of created groups is (display area / X scale) +1, {(100-5) / 5} +
It is 20 because 1 = 20.

Next, edit processing is performed on the first time-varying data. Since the input data value is 10.0, the Y coordinate is 10.0 × Y scale, so 10.0 ×
Since 3.0 = 30.0 mm, 30.0 is stored as the Y coordinate value. Then, the graph display edit table up to this point is added to the graph display means with the information that "the required display item is the item of display number 1". In the graph display means, the graph display processing 70 for the item of display number 1
Do 7.

By repeating the above to the 20th time change data, the graph shown in FIG. 9B can be drawn.

When the 21st time-varying data is reached, as shown in FIG.
The graph display change condition 1002 of 0 matches. here,
The graph display edit table shown in FIG. 12 is created.

First, regarding the number of sets to be created, the display of format 1 (1004) of change group 2 in FIG. 10 shows {(50
-5) / 5} + 1 = 10 pairs are required, and the format 2 (10
05) is displayed as {(100-55) / 5} + 1 = 10
The number of sets is required, and a total of 20 sets are secured. And up to the first 10 sets, as a graph type pointer,
Change the graph display content table Point to format 1 of group 1. The same format 2 is pointed to for the remaining 10 entries.

Next, the time change data that has been read so far is sequentially read from the time series data storage table, and each item of the coordinate Y and the data table pointer is created. Since the number of data processed up to now is 20, the compression rate is 20/10 = 2, and the maximum value, minimum value, and average value of two data are obtained, and the Y coordinate of each is calculated and stored. For the 21st data currently being processed, it becomes the data for the graph display edit table 11 entry,
This is the same as editing a line graph without compression.

The graph display edit table so far is
Information indicating that “display required items are items having display numbers 1 to 11” is sent to the graph display processing 707. In the graph display processing, the graph display processing is performed for the items of display numbers 1 to 11. When the data display location is at the rightmost end of the graph display area again, the graph display changing condition 1002 shown in FIG. 10 is satisfied again, and the above-described processing is repeated. That is, the compression rate automatically increases, and a large amount of data can be displayed in a limited display area.

FIG. 13 shows the configuration when this display system is used to display the learning convergence state in the learning of the neural network. FIG. 1301 shows a neural network learning device. In the case of the back propagation learning algorithm, which is a widely used learning algorithm for neural networks, since it is supervised learning, the value to be output by the neural network for input data must be prepared as teacher data.
The input data and the teacher data are stored in the input data storage unit 1302 and the teacher data storage unit 1306, respectively. The neural network unit 1303 is a multi-layer network, and stores the output value calculated from the input data through the network in the output data storage unit 1304. And the output value 1 of this neural network unit
304 and the value 1306 of the teacher data corresponding to the input data
Are compared by the comparison unit 1305. If the error value is larger than the reference, it is determined that the convergence condition is not satisfied, and the weight calculation unit 1307 causes the neural network unit 1303 to
Update the weights of. Learning a neural network
With respect to all the sets of a plurality of sets of input data and the corresponding teacher data, the weights are repeatedly updated until the error value becomes smaller than the reference.

Here, the error value which is the comparison result in the comparison unit 1305 is used as the time change data display device 13 of the present invention.
08 as time-varying data, which is shown in FIG.
It is displayed in a graph display format such as.

The present embodiment can be similarly implemented when showing the progress of automatic adjustment of the membership function in the fuzzy inference system. At this time, in the configuration diagram shown in FIG. 13, the neural network unit 1303 corresponds to the fuzzy inference unit, and the weight calculation unit 1307 corresponds to the membership function adjustment unit.

According to this embodiment, the error value in the learning process can be displayed in the format shown in FIG.
In part 1, the overall tendency, that is, whether it is in the direction of convergence or not, can be judged relatively quickly and without error, and in part 902 of the figure, the error fluctuation per learning unit can be grasped in detail. This has the effect of making it easier to predict the time required until the target convergence error is reached in the direction of convergence and clarifying the standard for ending learning. If it is not in the direction of convergence, the following means for convergence, for example, changing parameters for learning, changing the structure of the neural network, and obtaining clues to confirm the rationality of input data and teacher data can be obtained. it can.

Next, an embodiment in which a plurality of types of graph formats are overlaid and displayed on the same X axis will be described. Overlapping display means displaying in a plurality of graph display formats on the same X axis, as in 1405 of FIG. This 14
In the example of 05, the candlestick display and the broken line graph display are displayed in an overlapping manner. At this time, the display sections of the graph display content table are duplicated in a plurality of display formats as shown in FIG.
As shown in FIG. 1, a duplicate pointer column 1403 is provided in the graph display edit table, and when the graph display edit table is created, overlapping entries are linked as shown in FIG. 1404. Then, the input time-varying data is changed and realized as shown in FIG. FIG. 15 differs from FIG. 8 in processes 1501 and 15 concerning duplicate pointers.
02 is added.

Further, when the display interval of the data in the X-axis direction is reduced, it is sufficient to reduce the X scale. In the example in FIG. 10, an example of the graph display content table and the output image when the X scale is set to 2.5 are shown in FIG.
16 (a) and 16 (b). 1601 in FIG. 16B
20 of 1 to 20 of the input data of FIG.
The data is displayed with double the density in the X-axis direction with respect to the display of FIG.

The expansion and contraction in the Y-axis direction can be similarly performed by changing the Y scale.

A case will be described in which the time-varying data display of the present invention is used to display data from a measuring instrument that samples data in a constant cycle or an indefinite cycle.

In the time-varying data display of the present invention, the data input destination by the data input means in FIG. 1 is set to various measuring instruments connected to the computer system for process control such as process control and monitoring. It can be used to display process data. At this time, there is an effect that it becomes easy to visually recognize fluctuations in the plant. For example,
Data from each measuring device such as "dam water level" and "sewage inflow" in water supply and sewage control system and "contamination degree in tunnel" in ventilation control system in tunnel, etc. are fetched and displayed in the present invention. By compressing and displaying past data using a time-varying data display device, long-term time-varying data can be displayed in a limited area, and plant status changes can be grasped and monitored over a long period of time. can do. In addition, it is possible to compress and display unimportant parts (parts where there is no data change) in time-varying data, and as a result, parts that have changed significantly (important parts) can be emphasized, and the effect of preventing overlooking of plant fluctuations can be achieved. Can be expected.

Next, the display format defining means will be described.

The display format is defined in advance using a pointing device such as a mouse.
FIG. 17 is an example of a screen defining a display format. The contents of the above-mentioned table can be defined, setting items can be selected in a menu format, and numerical values and the like can be directly input using a keyboard.

Further, by providing a function for executing the display format definition as shown in FIG. 18A, it is possible to define it while the time change data is displayed. The function shown in FIG. 18A operates as follows.

In the case of registration, a graph display change condition table is created with condition types and condition values indicated by parameters, and the number of display types, start data,
Create a graph display content table with display contents.

In the case of deletion, the condition having the condition type and condition value indicated by the parameter is deleted from the graph display change condition table, and the corresponding entry in the graph display content table indicated by the condition is also deleted. . In the case of deletion, other parameters such as the number of display types, start data, and display contents are unnecessary, and dummy parameters may be used.

In the case of change, the graph display content table indicated by the change condition having the condition type and condition value indicated by the parameter is replaced with the number of display types, start data, and display contents which are also parameters.

When the definition is changed while the time change data is being displayed using the above-mentioned function, it may be desired to immediately redisplay the changed graph display format. The function for this is the function 1801 in FIG.

This function gives the condition type and the condition value as parameters, searches the graph display change condition table 1802 with the condition type and the condition value, and displays the graph based on the graph content table pointed to by the matching change condition. Perform processing. Blocks 1803, 1804 in FIG.
1805 are blocks 704, 705, and 705 of FIG. 7, respectively.
The process is the same as 707.
