The plant data is fetched from a plant data storage part 10 by a CRT display processing part 4 and outputted to the display unit 5, thereby improving the operability.

Description

Detailed Description of the Invention [Object of the Invention] (Industrial Application Field) The present invention relates to a plant data display device that inputs plant data and displays the plant data on a screen display such as a CRT. (Prior Art) Generally, industrial plants are monitored by inputting plant sensor signals into a process computer and displaying the values of the plant sensor signals on a CRT display. Figure 5 shows a conventional example of a plant data display device that displays plant signals on a CRT display. The plant data display device 1 is composed of a screen selection switch 2, a screen information data section 3, a CRT display processing section 4, a CRT display 5, a keyboard 6, an interaction processing section 7, and a screen selection processing section 8. , the process data Sp and the output of the screen selection switch 2 are stored in the plant data storage section IO via the process input section 9. Plant data storage unit lO
The plant signal Sp stored in is output to the CRT display processing section 4 together with the stored information of the screen information data 3 that stores the format of the CRT display screen. The screen selection processing section 8 inputs screen selection information from the information in the plant data storage section IO, and outputs the screen number requested by the operator to the CRT display processing section 4. The CRT display processing section 4 takes out the data of the selected screen number from the screen information data section 3 and performs display processing. The screen information display section 3 stores fixed screen display data for graphically displaying the plant system and variable section display data specifying which input data in the process data Sp is to be displayed at which position. ing.

The CRT display processing section 4 outputs the fixed screen display data to the CRT display 5 to graphically display the plant system, and also displays necessary plan 1-data from the plant data storage section 10 based on the contents of the variable section display data. , and create CRT display data for numerical display. It is output to the CRT display 5 and displayed.

Additionally, if the operator wishes to monitor plant data that is not displayed on the CRT display 5, the input data display function realized by the interaction processing unit 7 can be used to display data at any input point specified by the operator. ．． Input points are specified by entering computer processing symbols. The computer processing symbol is a symbol assigned to each input point, and the computer identifies the input point from this symbol.

To monitor any plant data, press keyboard 6.
Enter the computer processing symbol corresponding to the input point of the plant data that the operator wants to monitor. The output from the keyboard is output to the dialogue processing section 7, and the dialogue processing section 7 extracts the data of the corresponding input point from the plant data storage section 10 based on the computer processing symbol corresponding to the input point, and outputs the data to the CRT for numerical display. Create display data and display CRT display I
5 and display it. In this way, the plant status was displayed on the CRT display 5 and monitored by the operator.

(Problem to be solved by the invention) However, such conventional devices can only display plant data specified in the screen information data section.
Plant data that an operator wants to monitor is not always displayed on a CRT.

Also. It is difficult to display all plant data for each system on a CRT display screen due to the area limitations of the CRT display screen.

Therefore, when an operator wants to monitor process data that is not displayed on the CRT display screen, it is necessary to check the computer processing symbol of the plant data to be monitored and input it from the keyboard 6. Most of the plant data for the entire plant is input into the process computer, and there are a huge number of input points.To find the input point that the operator needs from among these, it is necessary to use the input point list (plant data display device). It was necessary to refer to a table that lists the calculation processing symbols and input point names for the process information that is being input, which was burdensome and time-consuming.

Therefore, in order to reduce the burden on the operator and display the values of the plant data to be monitored with a simple operation, the present invention displays the values of the plant data without being aware of the computer processing symbols of the input points. The purpose is to provide a plant data display device for

[Structure of the Invention] (Means for Solving the Problems) A plant data display device of the present invention includes a touch panel that outputs the coordinates of a touch position in response to a touch operation input on a screen display, and a touch panel that outputs the coordinates of a touch position on the touch panel. a touch input processing unit that determines the processing content based on the coordinates of the touch position; and a touch input processing unit that determines the processing content based on the coordinates of the touch position, the coordinate position of the sensor of the process data on the plant system diagram display screen, the sensor type, and the input point from the plant data storage unit. A window displaying the sensor type is output to a screen display processing section based on two data: a sensor information storage section in which indexes for searching are stored, an output of the double-sided selection processing section, and the sensor information storage section. At the same time, a sensor that determines the sensor type based on the touch coordinates, creates sensor position display data of the selected type, outputs it to the screen display processing section, and outputs the sensor type and screen number to the plant data display data creation section. Create data for displaying plant data specified by a touch operation from a position display data creation unit, the output of the touch input processing unit, the output of the sensor position display data creation unit, and the data of the sensor information storage unit. By including a plant data display data creation unit that outputs to the screen display processing unit, computer processing symbols of input points can be created! This allows plant data values to be displayed without any knowledge.

(Operation) The operator operates the screen selection switch to call up the screen for the system he wishes to monitor. Thereby, sensor information data corresponding to the selected screen is retrieved from the sensor information storage section. The sensor information storage unit stores what kind of sensor is located at which position on the front screen.
X-Y coordinates on the screen, sensor type, and computer processing symbols are stored.

From these data, the type of sensor used on the CRT display screen is searched, and a window showing the type of each sensor is displayed at the bottom of the CRT display screen.

The operator selects the type to be monitored from this sensor type window by touch operation. In this device, a sensor of the same type as the selected sensor is retrieved from the sensor information storage section, and the sensor position is displayed as a symbol on the CRT display screen. When the operator touches a symbol displayed on the CRT, data from the sensor information storage unit is retrieved based on the touch coordinates, sensor type, and screen number.
The computer processing record 3 is searched, the corresponding data is retrieved from the plant data storage section, and the plant data is displayed on the CRT.

Thereby, the plant data that the operator wants to monitor can be displayed through the operator's CRT touch operation.

In addition, in the sensor position display data creation unit l2, the screen No.
．． Then, the sensor information of the corresponding screen is retrieved from the sensor information storage unit l4. The sensor information stores the X-Y coordinates of the sensor position on the display screen, the sensor type, and the computer processing symbol. From these data, the sensor type is extracted and one window is created for each sensor type at the bottom of the CRT screen. The CRT display processor 48 creates data for display on the CRT display processor 48 and displays it on the lower part of the screen of the CRT display 5.

A touch operation from the operator is performed via the touch panel 15 attached to the CRT display 5, and the x-
The Y coordinate is output to the touch input section l1.

The touch input unit 11 determines whether to select the sensor type at the bottom of the screen or request to display plant data at the top of the screen based on the Y coordinate of the touch position, and selects the sensor position display data creation unit l2 or the plant data display data depending on the request type. Creation part 1

In these figures, the sensor information storage unit 14 in FIG. 3 includes a sensor information pointer table Tp at the beginning, and coordinates 31 of the sensor position on the system diagram screen 4l shown in FIG.
, 32. A sensor information table Ts storing a sensor type 33 and a computer processing number 34 is stored. This sensor information table Ts is created for each system screen. The sensor information pointer table Tp includes a sensor information table pointer Pi (i=1.2・
...n) are stored in the order of screen number, and the sensor information table Ts corresponding to each system screen is searched.

The process will be explained below along with the flow of the process.

When the screen is first displayed, only the fixed portion of the display screen 4l is displayed, representing the plant system, depending on the contents of the screen information data section 3, as shown in FIG. 4(a).
Further, when a screen is selected, the sensor position display data creation unit 12 retrieves the sensor information 31 to 34 of the corresponding screen from the sensor information storage unit l4 according to the selected screen number, and the sensor type 33 in the data. Take out everything.

When extracting the sensor type 33, the sensor type 33 is not extracted if it is the same type as the one previously extracted, so that data of the same type is not duplicated. Data for displaying the sensor type window 42 at the bottom of the CRT screen is generated from the extracted sensor type data. This data is created by preparing display data for each sensor type in advance, extracting the data of the type to be displayed from among these, and moving the Y coordinate to be displayed in the order of display to the right by the size of the window. It is output to the display processing section 4 as shown in FIG. 4(a). Also,
The sensor position display data creation unit l2 uses this sensor type window 4.
2 and the sensor type 33 are created and stored in the sensor information storage section 14. Here, when displaying plant data at a certain position on the system screen 4l, first select the sensor type 33 from the sensor type window 42 displayed at the bottom of the screen. The selection is CR
This is performed by performing a touch operation on the T display screen, and the x-y coordinates of the touch position are input from the touch panel 15 to the touch input processing unit 11 (201).

In the touch input processing unit 11, Y in the sensor type display window 42
The coordinate position is memorized, and based on the Y coordinate of the touch position, it is determined whether to select the sensor type 33 at the bottom of the screen or the plant data display at the top of the screen (202). Sensor type 33
In the case of selection, the x-y coordinates of the touch position are output to the sensor position display data creation unit 12 (203), and in the case of a request for plant data display, the X-Y coordinates of the touch position are output to the plant data display data creation unit 13 (203). Output I mark.

When the sensor type 33 is selected, the sensor position display data creation unit 12 displays the X-Yffl mark of the touch position and the
- It is determined which sensor type 33 has been selected from the correspondence data between the Y coordinate and the sensor type, and the sensor type 33 and the currently displayed screen number are sent to the plant data display data creation section 13. 6 Next, sensor type 3 is output for each point of sensor information of the currently selected screen from the sensor information storage unit 14.

Display data for displaying 3 is created (210).

If the sensor types>1+13:11 are different, no processing is performed.

This processing is performed for the number of sensor points in the sensor information table Ts of the screen number currently displayed on 7E stored in the sensor information storage unit 14, and when the processing for all the points is completed,
The sensor symbol display data is output to the CRT display processing section 4 (211). The CRT display processing section 4 outputs sensor symbol data to the CI{T display 5, and the sensor position is displayed on the CRT screen.

A display example in which the sensor symbol 43 is displayed is shown in FIG. 4(b).

here. By touching the sensor symbol displayed on the CRT screen, the x-y coordinates of the touch position are input from the touch panel 15 to the touch input processing section 11 .

When the sensor symbol 43 is touched, the X-Y coordinates of the touch position are displayed in the plant data display data creation section 13.
Output to. The plant data display data creation unit 13 first checks whether the sensor type 33 is selected (212). ! ! If not selected, no processing is performed. When the sensor type 33 is selected, the screen number currently selected is selected from the sensor information storage unit l4.
Extract sensor type 33 and sensor position coordinate 31.32 data on the display screen, which is data for one point of sensor information in the sensor information table corresponding to (213) to (216)
. Next, it is determined whether the extracted data is the same as the sensor type 33 selected and the X-Y coordinates of the touch position are the same as the sensor position coordinate data (217). If they are different, the data for the next point is retrieved from the sensor information storage section 14, and the determination is repeated until the same data is found or until all data search is completed. If the same data exists, the plant data display data creation section 13 retrieves the computer processing symbol from the sensor information storage section 14 (218).

The CIIT display processing unit 4 decodes this plant data display data, performs processing similar to conventional variable display data processing, searches for data from the plant data storage unit 10, and displays the plant data 43 on the CRT screen. Display as shown in Figure 4 (C).

As described above, according to this embodiment, plant data can be displayed by the operator touching the CRT surface screen without being aware of the computer processing symbols of the plant data.

In the above embodiment, the method of displaying the selected plant data on the CRT display 5 has been explained, but in another embodiment, a typewriter output section is newly provided and the output of the data creation section I3 is output to this. By doing so, it is also possible to print on a typewriter.

In addition, in the above embodiment, the plant data is sent to sensor type 3.
3 and the sensor position is displayed, but other classifications,
For example, it is also possible to classify and select based on the operating status of the plant.

Furthermore, although the method of selecting one point in the plant data is used in the embodiment described in -H, the plant data display creation unit 13 does not determine the sensor position and only determines the sensor type 33, so that the displayed data is not displayed. It is also possible to display a list by type of system on the screen.

Further, in the above embodiment, plant data is selected by touch operation on the CRT display screen, but similar processing can be performed using other pointing devices, mouse, trackball, light pen, etc.

[Effects of the Invention] As described above, according to the present invention, when an operator displays plant data that he/she wants to monitor, he/she does not need to be aware of the computer processing symbols of the plant data and can do so with a simple touch operation, resulting in improved operability. and speed up plant data display operations.

Also. The present invention makes it possible to display all the plant data input into the process computer on the screen, which replaces the meter on the operation panel and eliminates the need for a meter on the operation panel, saving space. ．．
