Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a touch operation device in which an operator operates plant equipment by touching a display screen of a display device.

(Prior art) In recent years, in the field of plant operation, instead of [panel operation] where monitoring/operation is performed using lamps, instruments, etc. on control panels and graphic panels,
``rCRT operation'' in which monitoring/operation is performed using symbols, par charts, numerical values, etc. on the CR7 screen is becoming mainstream.

Conventionally, this CRT operation has been mainly used for monitoring purposes, but recently, touch operations that also use this CRT for operation have gradually become popular. Touch operations allow monitoring and operation to be performed on the same screen, making it easy to understand the plant status.

Alternatively, many switches that were required on the panel can be replaced with touch-type switches (hereinafter referred to as touch switches) on the CRT screen.
There are advantages such as space saving by replacing it with .

FIG. 8 shows an example of a conventional touch operation device 1. As shown in FIG. The touch operation device inputs information on the control device 3 and plant equipment 4 inputted through the process input device 2 to the operation information display means 12 via the process input means 11 . The operation information input means 12 displays the input information on the display device 5. The touch sensor 6 detects the position where the operator touches the display device 5 . The touch input device 7 inputs the detected position and outputs it to the touch input means 13. The operation information processing means 14 is
Based on the position touched by the operator obtained from the touch input means 13, information necessary for operation output is processed. The operation output means 15 inputs the information processed by the operation information processing means 14 and outputs operation instructions to the process output device 8.
It is output to the control device 3 via.

The control device 3 receives operation commands, performs control processing, and outputs control signals to the plant equipment 4.

As described above, the touch operation device can easily operate plant equipment by touching the touch switch on the display device.

(Problems to be Solved by the Invention) As described above, the touch operation device is much easier to operate than the conventional hard switch operation. However, because it is easy to operate, there is a problem in that careless operations may occur that are contrary to the operator's intention.

In other words, when operating a conventional hard switch, the act of selecting the target hard switch must be followed by the act of twisting or pressing down, such as grasping and twisting the switch, or touching and depressing the button. Accompanied by the feeling of performing an operation. However, when operating a touch switch, you only need to touch it with your finger and do not have to twist or press down, so the feeling of operating it may be weaker than in the case of a hard switch.

Therefore, for example, when the operator points at the screen of the display device to explain, or when the operator carelessly touches the screen with his or her finger or clothing, an operation that the operator does not intend may occur. In particular, optical touch sensors detect positions by blocking the grid-like light rays running parallel to the display surface on the front surface of the display device, so there is no need to actually touch the display device. There is a possibility that careless operations may occur due to fingers, clothes, etc. that are outstretched and blocking the light passing through the front of the display device. FIG. 9 shows a case where an operator's carelessly put out finger inputs a position that is not intended by the operator.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above problems and provide a touch operation device that can be operated while confirming that the act of touching a touch switch is clearly based on the operator's intention to operate. do.

[Structure of the Invention] (Means for Solving Problems) In the present invention, an operation permission switch for permitting execution of a touch operation is disposed near a display device with a touch sensor, and this operation permission switch is operated. An operation command for operating the plant equipment is output only when the display operation screen is touched in the state.

(Function) The operator looks at the information displayed on the screen of the display device and
If you intend to operate, touch the screen of the display device while holding down the operation permission switch. Then, only in this case, an operation command is issued and the plant equipment can be operated. This prevents unintended operations and ensures accurate and reliable operations.

(Embodiment) An embodiment of the present invention will be described below, taking as an example a case where the present invention is realized using a digital computer.

FIG. 1 is a diagram showing an embodiment of the present invention. In the figure, No. 8
The same reference numerals as in the figure indicate the same or corresponding parts, and the touch operation device 3110 includes a process input means 11 for inputting information of the control device 3 and plant equipment 4 via the process input device 2, and a process input means 11 for inputting the information inputted. An operation information display means 12 that displays on the display device 1; and a touch input means 13 that inputs the position where the display device 5 is touched by the operator via the touch sensor 6 and the touch input device 7.
, the contact signal of the operation permission switch 21 is sent to the contact input device 2.
1, an operation information processing means 17 that identifies the device to be operated and its operation contents from the contents displayed on the display device 5 and the touched position, and creates an operation command. , an operation output determining means 18 that outputs the operation command created by the operation information processing means 17 to the operation output means 15 only when the contact signal of the operation permission switch 21 inputted from the contact input means 16 is ON;
and an operation output means 15 that outputs an operation command to the control device 3 that controls the plant equipment 4 via the process output bag M8.

Further, the operation information processing means 17 includes a touch content determination unit 171 that determines the touched content based on the touch coordinates;
Consists of an operation target specifying section 172 that specifies the operation target, an operation content specifying section 173 that specifies the operation content, an operation command specifying section 174 that specifies the operation command, and an operation command creation section 175 that creates the operation command output. .

Further, the operation permission switch 21 can be, for example, an automatic return type (spring type) button whose contact is ON only while being pressed, and can be installed, for example, in front of the left side of the display device 5 as shown in FIG. , press this operation switch 2 with your left hand.
It is conceivable that the operation displayed on the display device 5 may be performed by touching the screen part with the right hand while pressing down the button 1, but it goes without saying that this is not limited to this.

Next, the operation of the embodiment configured as above will be explained. The process input means 11 inputs information about the plant equipment 4 and the control device 3 via the process input device 2 . The operation information output means 12 displays the input information on a display device! Display output on 5. The touch input means 13 inputs the position where the display device 5 is touched via the touch sensor 6 and the touch input device 7. The operation information processing means 17 first performs a process of determining the touch content based on the position input by the touch content determination unit 171 and the displayed content. In this embodiment, the touch content is divided into the following three types and determined.

That is, among the operation screen parts, (1) when the device is touched, (2) when the operation switch is touched, (
3) This is a case where the operation command switch is touched. The operation command switch is a switch for confirming the operation content selected by the operation switch and finally outputting the operation command to the plant side.

FIG. 3 is an example of a screen when a pump is selected as the target device by touch. At this stage, the touch content determining unit 171 identifies the operation target as the pump 301 by the operation target specifying unit 172 . The operator selects an operation by touching one of the operation switches 302 and 303 on the screen. Here, the operation switch 302 is a start switch for the pump 301, and the operation switch 303 is a stop switch. When the operation is selected by touch, the touch content determination unit 17
1, the operation is specified by the operation content specifying unit 173. Further, when the operation command switch 304 is selected by touch, the operation command specifying unit 174 specifies the operation command. Based on the specified operation target and operation details,
The operation command generation unit 175 creates operation command data and outputs it to the operation output determination means 30.

In this embodiment, the operation permission switch 21 is determined to be 0N10FF for the operation command switch 304 that finally outputs the operation output to the plant side, that is, the device 301 to be selected and the operation switches 302 and 303 are touch-selected. In this case, the touch is accepted regardless of the 0N10FF of the operation permission switch 21, but when the operation command switch is selected by touch, the touch selection is not accepted only when the operation permission switch 21 is ON. wear. If an operation command is touched while the operation permission switch is OFF, the touch is considered invalid and the operation output is blocked. The above determination process is performed by the operation output determination means 18. If it is determined that the operation command is to be output, the operation output means 15 outputs the operation command to the control device 3 via the process output device 8, and the plant equipment 4 is operated.

FIG. 4 is a flowchart showing the processing contents from the touch input means 13 and the contact input means 16 to the operation output means 15. When a touch input is made on the operation screen portion of the display device 5 via the touch sensor 6 (401), the content of this touch is determined (402), the device (403), or
Specify the operation (404) or operation command (405). When the operation command is specified, an operation output command is created (40
6). At this time, the state of the contact input from the operation permission switch 21 is checked (407), and if it is ON, the operation output command is executed (408), and if the operation permission switch is OFF, the operation output is blocked. .

In the above embodiment, the operation permission switch 21 is.

Although a push-button switch is used, it goes without saying that similar effects can be obtained by using a push-button switch or a twist-type switch instead.

In addition, in the above embodiment, equipment such as a pump is the target of operation, but the target of operation is not limited to plant equipment. For example, the target of operation is an automatic operation switch or a switch of a controller. It is clear that the same applies to both.

Furthermore, in the above embodiment, the input/output between the touch operation device IO, the plant equipment 4, and the control device 3 is 1.
Although the process input/output device 2.8 uses real signal lines, an input/output device with a multiplex transmission configuration may be used instead.

Further, in the above embodiment, the operation permission switch 21 is 0N1.
Although 0FF is valid only for operation commands, it may also be valid for touch selection of the operation target and touch selection of the operation content.

Furthermore, in the above embodiment, three steps were required: touch selection of the operation target, touch selection of the operation content, and touch selection of the operation command, but in order to simplify the steps,
Eliminates the operation command switch and allows touch selection of the operation target and operation content.

It is also possible to output operation commands to the plant side.

FIG. 5, FIG. 6, and FIG. 7 are diagrams showing examples in this case. In the figure, the same reference numerals as in FIGS. 1 and 3 indicate the same or equivalent parts, and the touch content determination unit 171 classifies and determines the touch content into the following two types. That is, when the operation target 301 is touched, and when the operations 302 and 303 are touched. The selection of the operation is accepted only when the operation permission switch 21 is turned on after the operation target is selected by touch. If an operation command is touched while the operation permission switch 21 is OFF, the touch is considered invalid and the operation output is blocked.

FIG. 7 is a flowchart showing the processing contents from the touch input means 13 and contact input means 16 to the operation output means 15 at this time. When a touch input is performed on the operation screen portion of the display device 5 via the touch sensor 6 (701), the content of the touch is determined (702), and the device (702)
03) Or specify the operation (704).

When the operation is specified, an operation command is created (705), and when the operation permission switch 4 is ON (YE at 706).
S), the operation command output is not executed (707), and when the operation permission switch is OFF (NO in 706), the operation output is blocked.

(Effects of the Invention) As described above, according to the touch operation device of the present invention, it is possible to operate the touch switch while confirming that the act of touching the touch switch is clearly based on the operator's intention. As a result, accurate operations can be carried out, making it possible to operate the plant with higher safety and reliability.
