Abstract

PURPOSE:To improve the responsiveness in terms of human engineering and to prevent a malfunction and wrong decision therefore to reduce the fatigue of an operator, by producing the hierarchical information with a plant monitoring system and retrieving and displaying said information successively on a display screen. CONSTITUTION:A pressure point position sensor 4 contains a transparent film which is put over the screen of a CRT display device 1. Thus the CRT screen can be observed through said transparent film, and the position information on the screen corresponding to the relevant part is supplied to a computer 3. For instance, an operator wants to display the data belonging to the group of the data 1.1. In this case, the pressure is applied to the part where the data 1.1 is displayed by means of the sensor 4 while the display is observed. Then the position information is supplied to the computer 3, and an item list of the 2nd tier belonging to the data 1.1 is displayed to the device 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control and monitoring device for controlling a plant process using a computer.

FIG. 1 is an explanatory diagram showing the configuration of a conventional device, in which (1) is a cathode ray tube display device, (2) is a keyboard, and (3) is a computer. The computer (3) inputs signals from the plant, monitors the state of the plant, outputs control signals to the plant, and performs process control of the plant. The cathode ray tube display device (1) is sometimes called a graphic display device or a character display device, and can display characters, figures, and other images, and together with the keyboard (2), serves as an interface between the computer (3) and the operator. It consists of

Various types of information regarding the plant status that should be displayed to the operator are stored in the computer (3), and this information is organized and edited into figures or character strings for each building and displayed on the cathode ray tube display (1). ), but
In conventional devices, a so-called ID number is assigned to each type of figure or character string to be displayed on a CRT display device.
Entification Number ) (individual number) is determined! l) A correspondence table between IDN0 and display information is stored on the system in the form of many files or as a document.

The operator checked this correspondence table to find out which information was desired to be displayed, and entered the IDN0 from the keyboard to display the information on the cathode ray tube display (11).

However, when the number of items to be collected in the correspondence table between IDN0 and display information increases, it becomes cumbersome for the operator to search for the IDN0 of the information he wants to display from this table and input that ID number from the keyboard. It had the disadvantage of becoming a thing.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and all the data to be displayed is classified in a hierarchical manner, and the first layer item table in the first layer classification and this first layer For each item in the item list, the second
In the order of classification, each second layer item table collects all item names of the hierarchical classification, each lowest layer item table stores a classification table in which information names are collected, and the item table in the upper layer classification is stored. By displaying the item list of the lower hierarchical classification for the m-th item specified by the operator from the item list, the operator can easily display desired information.

Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 2 is an explanatory diagram showing an embodiment of the present invention, in which the same reference numerals as in FIG. 1 indicate the same or corresponding parts, (4) is a pressure point position sensor, and (5) is a pressure point position sensor. This is a controller for (4). As shown in Figure 2, the pressure point position sensor (4
) has a transparent film surface that covers the display surface of the cathode ray tube display device [1>, through which the display surface of the cathode ray tube display device (1) can be observed, and a part of the film surface. By applying pressure to the area, positional information on the display surface corresponding to that area is input to the computer (3).

By the way, in this invention, the information to be displayed on the cathode ray tube display device (1) is classified in a hierarchical manner, and FIG. 3 is a drawing showing the hierarchical classification used in this invention. Contains all data, data 1.
1, 1.2, 1.3... indicate the classification of the first layer, and data 1.1.1, 1.1.2, 1.1.3- indicate the classification of the second layer of data 1.1. This indicates the classification.

In this way, the information is stored in hierarchical classifications, and the information item tables to be displayed are collected in the lowest hierarchical classification. Such a classification table is stored in the memory of the computer (11) and displayed in a predetermined display method at the request of the operator. FIG. This is the first layer item table that is displayed first when the operator requests display.It is displayed as a character string as shown in the figure.For example, (6) is the first layer data 1.1, and (7) is the same. When the operator wishes to display data belonging to the classification of data 1.1 (6), the operator uses the pressure point position sensor (4) while observing the display shown in Figure 4. , data 1.1
When pressure is applied to the area where (6) is displayed, the position information is input to the calculator (3), and the calculator (3) receives this position information and information that the currently displayed data is data 1. Therefore, Chita receives a request to display the item table belonging to data 1.1 (6), and displays the second layer item table belonging to data 1.1 as shown in Figure 5 on the cathode ray tube display device (1). to be displayed. In the example shown in FIG. 3, assuming that the items in the second layer of classification represent the types of figures to be displayed (corresponding to IDN0 in the conventional method), (8) in FIG. 5 is data 1.1. The part that represents 1, (9) is the part that represents data 1.1.2, and the operator
．． 1.1, apply pressure to the area where data 1.1.1 (8) is displayed using the pressure point position sensor (4) while observing the display shown in Figure 5. Once added, the position information is input to the computer (3) and data 1.
1.1 is displayed as shown in FIG. 6, for example.

In addition, when you want to quickly convey to the operator information that should be managed by the operator, such as a plant abnormality, the items in each hierarchy classification to which the information belongs are shown in different colors or with flickers to draw the operator's attention. The part of the graphic or character string associated with the plant abnormality can be shown in a different color or with a flicker.

As described above, according to the present invention, the information in the plant monitoring system is hierarchical and configured so that it can be sequentially searched and displayed from the display screen, thereby improving ergonomic responsiveness and preventing malfunctions and misjudgments. This has the effect of preventing plant operation and reducing operator fatigue, leading to improvements in plant operation and monitoring functions.
