  First, the screens displayed on the terminals 9 and 10 will be described with reference to FIG. As the display screen, three screens of layer A21, layer B22, and layer C23 shown in FIG. 5 are respectively created, and these three screens are superimposed to create a superimposed display screen 20.

  In layer A21, a command list display image 24a on which a command list related to log data is displayed, and a mark for identifying a command (input from a penlight, a mouse, a keyboard, etc.) whose response characteristics or timing is appropriate are displayed. Display request check image 24b and a command content display image 24c in which the content of the command generated from the log data transmitted from the console 6 is displayed in text. Each command name in the command list display image 24a and the identification mark in the display request check image 24b are color-coded for each command.

  In the layer B22, a plurality of graph images 25a and 25b created by a plurality of telemetry data transmitted from the telemetry database server 4 are displayed. Although not shown, the name of the graph, the maximum value, the minimum value, and the unit of the graph are displayed at the top of each graph.

FIG. 5 shows a case where there are two graph images, but the present invention is not limited to this. For example, a total of 10 graph images of 2 columns and 5 rows can be created and displayed. .
The right end of the graph always shows the value at the current time, and the left end shows the past value before a predetermined time (for example, 100 seconds before).

  In the layer C23, command lines 26a, 26b, and 26c indicating a plurality of vertical command line generation time displays at positions corresponding to the transmission times of the commands transmitted from the console 6 (the right end is the current time). Is displayed. This line extends over the above-described graph images 25a and 25b. Further, the command generation time display images 26a, 26b, and 26c match the colors of the above-described color-coded commands.

Each terminal 9, 10 can use a general-purpose personal computer.
As shown in FIG. 6, each layer A, C, and layer B is created by an individual program. That is, a telemetry display program and a command display program are written on a recording medium 33 such as a CD-ROM.

  Then, the CD-ROM 33 in which the above-described program is written is inserted into each terminal 9, 10, and the telemetry display program 34 a and the command display program 37 a are installed in the hard disk 38. When the two programs are activated, the telemetry display program 34 a and the command display program 37 a in the hard disk 38 are loaded into the memory 30.

(5-1) Display of Telemetry Data The processing shown in FIG. 7 is performed by the telemetry display program 34b in the installed memory 30. The telemetry display program 34b is activated (step S30). In the telemetry display program, various information corresponding to each data identification symbol (data identification symbol, graph name, graph maximum value, minimum value, unit, graph color, and other various text data) Set as standard.

  In the program, the type of telemetry data that is displayed first when the terminal is started is set. Then, periodically (for example, every 0.5 seconds), a plurality of telemetry data transmission requests (data identification symbols are transmitted) to the telemetry database server 4 via the data relay servers 7a and 7b (steps). S31).

  The desired telemetry data (data identification symbol, latest measurement value) is received from the telemetry database server 4 (step S32), and additionally stored in the telemetry data memory 39 (step S33). A layer B shown in FIGS. 5 and 7 is created by the telemetry display program 34b based on each stored telemetry data (step S34), stored in the image memory 31, and then displayed on the display device 32 (see FIG. 5). Step S35).

  Next, it is determined whether or not the requested telemetry data has been changed (step S36), and if it has been changed, it is reset (step S37). Then, periodically (for example, every 0.5 seconds), a plurality of changed telemetry data transmission requests (data identification symbols are transmitted) to the telemetry database server 4 via the data relay servers 7a and 7b. (Step S38). The changed telemetry data (data identification symbol, latest measurement value) is received from the telemetry database server 4 (step S39), and stored at the head of the telemetry data memory 39 (step S40). The past data already stored in the telemetry data memory 39 is shifted one by one, and the old telemetry data (for example, 100 seconds before) is deleted (step S41).

  The updated data in the telemetry data memory 39 and various information corresponding to each data identification symbol set in the program (data identification symbol, graph name, graph maximum value, minimum value, unit, graph Layer B22 is created based on the image data and other text data), stored in the image memory 31, and then displayed on the display device 32 (step S42). Thereafter, it is determined whether or not to stop (step S43). If the operation is continued, the process returns to step S36.

(5-2) Display of log data In parallel with the creation and display of telemetry data, layers A and C are created by the command display program 37b of the installed memory 30. The principle will be described with reference to FIG. The command display program 37b calculates the display content at time t of each log data recorded in the log data memory 40, and creates a display image. The result is stored in the image memory 31, and command lines 26a, 26b, and 26c are displayed on the display device 32 on the layer C23a.

  In the next processing step, instead of calculating the display contents again, a display image in which the coordinates of the change in time are shifted is created. The result is stored in the image memory 31, and the event lines 26a, 26b, and 26c moved to the left are displayed on the layer C23b on the display device 32 as shown in the center row of FIG. Similarly, in the next processing step, as shown in the third row of FIG. 8, command lines 26b and 26c further moved to the left are displayed. In the third row in FIG. 8, the oldest command line 26a has been deleted because a certain time (for example, 100 seconds) has passed.

  Specifically, the process shown in FIG. 9 is performed. First, the command display program 37b is activated (step S50). In the command display program, various information (data name, line color, various text data, etc.) corresponding to each data identification symbol, command name list, etc. are set as standard.

  Periodically (for example, every 0.5 seconds), the current time of the telemetry data display function is acquired (step S51). Then, layer A is created (step S52), and layer C is created (step S53). Note that the command line is not displayed in the initial state.

  Next, the command list display image 24a of the command name list is displayed on the layer A (step S54). It is determined whether a command to be displayed has been set (or changed) (step S55). If set (or changed), a display command is set (step S56), and a command name list is displayed on layer A (step S54).

  Next, it is determined whether or not a command displayed on the command list display image 24a for command line display has been selected (clicked) (step S57). If not, it is next determined whether or not there is a selected command (step S58). If there is a selected command, it is determined whether the transmission time in each log data (data identification symbol, command type and transmission time) is within the display range of Layer B (within 100 seconds) (step S59). If not, the command line is not displayed (step S60) and the process proceeds to step 72.

  If it is within the range in step 59, a command line is displayed on layer C (step S61). At this time, the display position is shifted by the difference time as described above, and no new display position is calculated. Thereafter, the process proceeds to step 72.

  Returning to step S57, if a command is selected, it is determined whether or not the command to be selected has been selected (step S62). If not, a transmission request for the desired log data is sent to the command database server 8 via the data relay servers 7a and 7b (step S63). If there is a transmission from the requested log data (data identification symbol, command type and transmission time) from the command database server 8, it is received (step S64) and stored in the log data memory 40.

  Then, a command selection mark is displayed on the layer A display request check image 24b (step S65). Information such as command execution time and various text data is displayed on the command content display image 24c of layer A based on the transmitted command data and data in the command display program (step S66). Next, the display position of the command line is calculated (step S67). Then, the command lines 26a, 26b, and 26c are displayed on the layer C across all the telemetry graphs (step S68).

  Returning to step 62, if the selected command is clicked again, it is determined that display of the command line is unnecessary, and the command selection mark of the display request check image 24b of layer A is hidden (deleted) (step S69). . Information such as the command execution time and parameters of the command content display image 24c of layer A is also hidden (deleted) (step S70). Then, the command line 26a (or 26b, 26c) of the layer C is also hidden (step S71).

  Finally, it is determined whether or not to stop (step S72). If not stopped, the process returns to step S55.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications may be made to the specific structure within the scope of the present invention. . For example, when the Internet is used for communication between the terminal and the telemetry database server 4 and the command database 8, by assigning a storage medium such as a CD-ROM in which a telemetry display program and a command data program are stored, and password data, A general-purpose personal computer can be used for display. The command data (single data) of the layer C23 displayed on the terminals 9 and 10 can be displayed using graphs and figures.
