Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improvement in a monitoring console for monitoring and selectively controlling plant equipment.

[Technical background of the invention and its problems]

Conventionally, in this type of plant monitoring console, input signals from the operator are processed using a node-like method using a relay circuit or a dedicated board, and a method using a dedicated arithmetic and control device. There are two ways to set up a system and process it using software, but recently there is a strong need for monitoring and control equipment to be more compact and highly functional, and there is an increasing trend of adopting the latter method because it is easier to meet these needs. .

FIG. 1 shows the system configuration of a conventional plant monitoring console using a computer control device.

In Figure 2, when an operator selects and controls plant equipment from the console, the operator presses the operation switch 8, which is a command input device, on the plant monitoring console, and the signal is digitalized. The input device t5 detects the detection and notifies the arithmetic control device 1gl device 3.The arithmetic control device 3 processes the signal according to a pre-installed program and issues an operation command to the corresponding controller 10. To output,
It executes an output command to the digital input device 6. Incidentally, the result of the operation output can be detected by the digital input device 5 detecting the status signals 9 of the plant (several devices), and can be known on the monitor 1 via the arithmetic and control device 3 in the same manner as described above.

FIG. 2 shows an example of the operating section of the plant monitoring console explained in FIG.

In the figure, the configuration of the operation section includes operation switches SSn, MSn (n21+2, . . . ) on the operation pile 20.
) and card plates CPn (n21.2 .) for grouping the operation switches. Here, the operation switches Ssn, V on the operation panel 2o
fli of lsn! The number of ifs and arrangement vary greatly depending on the number of equipment in the target plant and the operating method. That is, the operation method includes an operation switch for specifying an operation item (this is referred to as selection switch SSn), and all selection switches 5Sr.
The operation switches (referred to as master switches MS n ) which are common to the i and which determine the input command size for the operation item, the cut command, etc. are divided into 24'df MK, and the operation output signal is determined by the combination of these switches. The two-behavior method is preferable, but since at least one operation switch is required for each item (for example, one device to be operated), it is necessary to arrange them on the operation panel. The number of operation switches increases as the number of operation items increases, and the required area of the operation panel 2θ also increases. Similarly, as the number of switch groups increases, the number of CPnOs increases, which causes an increase in the area of the operation panel 20.

In addition, if the operator actually selects, for example, the group Avc
If you want to turn off the "NO, 1 pump" that is connected to i%, the operation procedure is to search for the card plate cP1 corresponding to the group AVC from among the card play CPnO displayed on the operation panel 20. 1 operation and the selection switch belonging to the corresponding group.
This consists of a second operation in which the smoke selection switch SS indicating NO, 1 pump 1 is located and pressed down, and a third operation in which the master switch tJsn is located and pressed down.

However, in the first operation of this hanging stand, it is necessary to look around the entire panel to find the card play CP, and if there are many card play CPnO or the operation panel area is large, it is difficult to quickly Processing becomes difficult. In addition, 1 Eisaku switch 6 S n +
When the number of V S n is large, the same applies to the second and third operations, respectively.

In other words, ■ the number of operation items (/?C)
(The number of Kurisaku switches changes, so the operation
．． The size of the switch 20 and the layout of the switches are outside the scope of the plant, and it is necessary to design to accommodate this.

■Operation switch S S n + 1VlS n Due to the increase in the number of card plates CPn, etc., the operation panel 2
The size 0 also has the disadvantage of being stiff and difficult to operate.

[Purpose of the invention]

The present invention has been made to solve the above-mentioned seven prior art problems, and its purpose is to make it possible for the size of the operation panel to be unaffected by an increase or decrease in the number of operation items, and to have good operability. Is to provide plant monitoring operations east.

[Details of the Invention 1] In order to achieve the above object, the present invention allows input signals from an operation unit to be input to a plant monitoring console that monitors plant equipment and controls selection through an arithmetic and control unit, without being able to handle it independently. Multiple push buttons with no fixed meaning 11
A multi-item input keyboard consisting of a multi-item input keyboard main body and a data setting booklet containing items such as operation item names that can be assigned meanings to the push buttons is used as an input device for the operation section. It is characterized by being used as 1.

[Embodiments of the invention]

Hereinafter, a detailed example of the present invention will be explained with reference to the drawings.

FIG. 3 shows an example of the outer structure of a plant monitoring console according to the present invention, which is composed of a main body section 30 containing an operation pile 20, a monitor 1, and an arithmetic and control unit.

The booklet is bound with a ring 42 and attached to the keyboard body 43.

FIG. 5 shows an example of a system configuration of a plant monitoring console in which the multi-item input keyboard is applied to the control section, and the same parts as in FIG. 1 are shown with the same symbols. In the figure, a push button 51 for operation switches provided on the multi-item input keyboard main body 43, a page discrimination key 52 for detecting the currently opened page of the booklet, and a push button 51 for operation switches included in the multi-item input keyboard main body 43, An encoder 53 that converts the pressed state of the push button 51 and the page discrimination key 52 into information that can be exchanged with a keyboard interface 50 (described later), a keyboard interface 50 that reads the output of the encoder 53 and notifies it to the computer control device Ft, 3; A calculation f5 control device/13 that processes signals from the interface 50 according to a pre-installed program, a digital output branch 6 that outputs operation commands to the corresponding device 10 according to the processing results of the arithmetic and control device 3, and a status signal 9 of the device 10. It is composed of a digital input device 5 that reads the data and notifies the arithmetic and control device 3, a monitor 1 that displays the plant status based on the processing results, and its interface Z.

Next, the operation of this configuration will be described. In the operation section shown in FIG. 4, each pushbutton on the multi-item input keyboard main body 43 does not have a fixed meaning by itself, but the pushbuttons can be pressed by writing the operation item name on the data setting mat 41. Give it meaning, or meaning. Therefore, there is no need to consider the arrangement of selection switches and master switches on the operation panel 20 according to the operation items, and it is sufficient to simply write the necessary operation items on the data setting mat 41. Recognize.

In addition, since the data setting mat 47 is bound with a ring 42 and has a booklet structure, if the operation items cannot be filled in on the data setting mat 41 within one page of the spread, the same operation items can be written on the next page of the booklet. By additionally writing , it is possible to increase the number of operation items without changing the number of push buttons.

Furthermore, when it is necessary to divide the operation switches into large groups because the target plant is divided into several pieces of equipment, etc., use 4 spread data setting mats for each group, and write the group name in a spread. By writing the names in the index section 41a of the data setting mat 41, a desired group can be quickly detected from among a large number of groups to choose from.

In the above embodiment, the data setting mat (I K f
