Abstract

PURPOSE:To dispense with the generation of a temporary data so as to improve the debugging efficiency, by causing a picture display detecting section to determine a screen image to be displayed on a CRT by using information from a picture format storing section and a temporary data storing section. CONSTITUTION:A display request to a CRT 5 is made from an external device 6 to a picture display determining section 4. The section 4 determines a picture image displayed on a CRT 5 by using the information of a picture format storing section 2 and data storing section 3 or screen format storing section 2 and temporary data storing section 7 and displays the determined screen image on the CRT 5. When the temporary data are used, whether or not the temporary data are generated in the temporary data storing section 7 is retrieve. When the temporary data are generated, data are fetched in accordance with a display information index. By previously preparing only one temporary data in such way, a screen format can be debugged any number of times without generating the temporary data individually at every picture.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a screen having a test output function that enables debugging of screen formats 1 to 1 in a process computer system in the absence of actual data to be displayed on a CRT. This relates to display methods.

[Technical Background of the Invention] In a process computer system that performs power system control, it is possible to calculate the daily total power generation capacity of each power plant, the hourly power generation amount of a certain power plant, or the total power generation capacity of a certain power plant in a certain month. It is necessary to display recorded information such as daily average power output, and instantaneous value information that changes from time to time, such as power, voltage, frequency, etc. in the power system, on a CRT in a timely manner. The number of screen images displayed on the CRT varies depending on the system, but at least 2
00 sheets are required. In order to display a screen image on a CRT, data constituting the screen image (for example, data including the amount of power generated by each power plant, etc.) and a screen format that defines the screen image output format are required.

” The output format includes the XY coordinates of the output position of the screen image on the CRT, data type (integer type, real number type, character type, etc.), number of output data digits, color information, presence or absence of blink display, and This is the location of data that stores the data that makes up the screen image (for example, the amount of power generated by each power plant).

One screen format needs to be prepared for each screen image, and it is necessary to debug the screen format to determine whether the prepared screen format matches the intended screen image.

Further, the data stores, for example, actual numerical values such as the amount of power generation among the data constituting the screen format. Numerical data such as this generated power G is updated in accordance with actual changes. In order to similarly update the screen image data on the CRT, the target data must exist at the position defined by the screen format.

When both the above screen format and data exist,
By issuing a display request to the computer, a screen image can be displayed on the CRT.

FIG. 7 is a functional block diagram illustrating a conventional screen display method, and FIG. 8 is a schematic diagram of processing, which will provide an overview of the conventional method.

In Figure 7, 1 is the screen format and data CI
An input device such as a floppy disk or a card reader that inputs data into the storage section of tT; 2.3 is a storage section for the screen format and data inputted from the input device 1; 4 is a storage section for storing the screen format and data inputted from the input device 1; A screen display determining unit 6 determines the screen image to be displayed on the CRT 5, and a screen display determining unit 6 determines the display target screen number and the display target CRT number to the screen display determining unit 4.
and an external device, such as a console CRT, that makes a display request such as specifying data to be used for display.

Then, by outputting a display request from an external device to the screen display determining section 4, the screen format and data created in advance in the screen format storage section 2 and data storage section 3 are input to the CRT 5.

[Problems with the Background Art] In the conventional method described above, at the time a request to display a screen image is sent to a computer, it is necessary that both the screen format and the data for the display request screen have been created. .

However, as a system creation procedure, screen formatting and data creation do not necessarily end at the same time, and even when an error occurs, it is difficult to determine whether the cause of the error is on the data side or the screen formatting side. It was unclear and difficult to debug. Therefore, for screen format data, each debugger prepares temporary data and issues a display request to the computer. However, in systems with a large number of screen images, this method imposes a heavy burden on creating temporary data for each screen image, which is a major cause of lower debugging efficiency.

[Object of the Invention] The present invention has been made to solve the above-mentioned problems, and provides a screen display method having a test output function with high debugging efficiency that eliminates the need to create temporary data that has been created by each debugger in the past. is intended to provide.

[Summary of the Invention] The present invention achieves the above object by providing the screen display determining section with the following functions.

A function to analyze and store each instruction item in 0 screen format.

■The ability to analyze, read out the stored information, refer to the position of data within the information, and import and edit the data.

■In the case of temporary data output, follow each output format instruction from the screen format stored in ■, create a display information index that correlates with the temporary data prepared in advance, and data according to the display information index. A function to import, process, and assign as a screen image for test output.

[Embodiments of the invention] Examples will be described below with reference to the drawings.

FIG. 1 is a functional block configuration diagram of an embodiment illustrating a screen display method according to the present invention. In Figure 1, the seventh
Components that are the same as those in the drawings are given the same reference numerals and their explanations will be omitted. 7
is a storage unit for temporary data, and when data does not exist in the data storage unit 3, or when data exists but is output as temporary data, information from the screen format storage unit 2 and temporary data storage unit 7 is used. Then, the screen display determining unit 4 selects the CRT 5.
Determine the screen image to be displayed.

8 is a display information index indicating the relationship between temporary data and screen format.

These elements operate at the following timings. First, the external device 6 issues a display request to the screen display determining section 4 on the CRT 5. The screen display determining unit 4 uses the information in the screen format storage unit 2 and the data storage unit 3, or the screen format storage unit 2 and the temporary data storage unit 7, to display the information on the CRT according to the flowchart shown in FIG. 2, which will be described later. Determine the image of the screen to be used. This determined screen image is displayed on the CRT 5.

FIG. 4 is an example of a screen image displayed in the flowchart of FIG. 2. Of the screen images in Figure 4,
The amount of power generated by each power plant is information in the data. FIG. 3 shows a schematic diagram of the screen display processing of the present invention.

Next, the flowchart shown in FIG. 2 will be explained.

The processing in the flowchart of FIG. 2 is executed in response to a display request from the external device 6. The screen display determining unit 4 first searches the screen format storage unit 2 to determine whether the screen format of the screen requested to be displayed in step 20 has already been created.

If the requested screen does not exist in this search process, the determination process in step 21 proceeds to the error process in step 213 and ends as "no display screen exists".

If the judgment in step 21 is YES, proceed to the next step 2.
In step 2, it is determined which of the temporary data and the actual data should be used as screen image data, based on the data classification flag specified at the time of the display request from the external device. The process in step 22 is determined in step 23, and if actual data is to be used as data regarding the display request screen, a search is made in step 24 to see if the data has been created in the data storage section 3.

The processing in step 24 is determined in step 25, and Y
In the case of ES, as the processing in step 26, the information necessary for the screen image among the existing data is extracted from each data according to the screen format instruction, and is associated with the screen format searched in the processing in step 20.
In step 7, the information extracted in step 26 is subjected to processing such as converting the data type, determining the number of output digits, determining color information, and determining blink display so as to match the output format in the screen format, and the screen image is determined. do.

On the other hand, if temporary data is to be used, a search is made in step 29 to see if temporary data has been created in the temporary data storage section 7. The judgment in step 29 is made in step 210, and if temporary data has been created, step 211
Then, data is extracted according to the display information index that associates the created temporary data with the output format indicated by the screen format searched in step 20.

FIG. 5 shows a schematic structure of the display information index, and FIG. 6 shows a schematic structure of temporary data. The NO at the left end of each diagram serves as a key that associates each piece of information. In other words, in FIG. 5, the information whose leftmost NO is 1 indicates the output location, color, digit, etc. as a screen image, and according to the output format indicated by this information, the information whose leftmost NO is 1 in FIG. Output the contents. This display information index is created at the same time as a screen display request is issued. After the process in step 211, the process in step 27 is performed in the same way as the actual data processing.

Also, if the temporary data does not exist as determined in steps 25 and 210, the error processing in step 212 determines that "data does not exist" and ends the process.Then, the image of the display request screen determined in step 27 is displayed in step 28.
to display on CRT 5.

Although the above embodiment has been described as a process TSM system, the system is not limited to this, but it can be used as a system that requires the display of a large number of screen images and the display of the screen images is related to data. Effective. The means for outputting to the storage section is not limited to floppy disks and card readers, but can be replaced by means having equivalent functions.

[Effects of the Invention] As detailed above, according to the present invention, by preparing only one piece of temporary data in advance, the screen format can be changed as many times as necessary without having to create temporary data individually for each screen. Debugging becomes possible. Since separate temporary data for each screen format is not required, processes such as data creation and registration are unnecessary. Therefore, it is possible to provide a screen display method that has an output function that allows debugging of screen formats that are highly effective for systems with many screen images.

Note that by outputting the display information index in LP ratio, it is possible to provide a debugging method using a visual check using a list in addition to debugging based on screen output.
