When the switch 42 is operated under such conditions, the device corresponding to the blinking symbol 11 is selected and operated. When the symbol 11 corresponding to an undesired device blinks, the touching point is moved on the panel 41 by reference to the CRT 10. Then the switch 42 is operated when the symbol 11 corresponding to a desired device blinks. As a result, the operability of an operator is improved and at the same time it is possible to flexibly cope with the change, etc., of the equipments.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a supervisory control device equipped with a display device for graphically displaying monitored objects such as factory electrical equipment and production plants.

(Prior Art) In the monitoring and control of factory electrical equipment, production plants, etc., CRTs or graphic panels are used as display devices that classify and display the status of monitored objects. In addition, since the case of a graphic panel is the same as that of a CRT,
In the following explanation, only CRT will be explained.

FIG. 4 shows an example of a conventional monitoring and control system for electrical equipment using a CRT, in which numeral 10 is a CRT, and the screen shows equipment symbols 11 and 11 indicating equipment to be monitored by the system.
are displayed, and the control computer 30 for monitoring operation is further provided with a display function 31 for displaying these symbols 11 in red, green, or the like.

That is, the control computer 30 inputs and outputs signals to and from the on-site electrical equipment 50, and also controls the display function 3 as necessary.
A display request is made to the CRT 30 via 1.

Reference numeral 40 denotes an operation panel, which operates the device symbol 11 on the CRTIO and requests the control computer 30 to perform output such as turning on/off the actual device.

Generally, in such a system, a graphical display corresponding to the target equipment is displayed on the CRTIO, and a symbol 11 indicating the equipment is displayed therein.

The control computer 30 collects information from the field equipment 50, edits the contents, and displays the information from the field equipment 50 via the display function 31.
The device symbol 11 is lit in red, green, etc. in response to the on/off status.

Through such a procedure, the status of the on-site equipment is always displayed on the CRTIO, and the operator can monitor the equipment from a monitoring room or the like that is separate from the actual equipment.

In order to perform monitoring operations, it is important to turn on and off the on-site equipment while monitoring the CRTIO, and the operation panel 40 is used to operate the on-site equipment.

Generally, the operation panel 40 is equipped with a device selection switch corresponding to the device symbol 11 on the CRTIO, and the operator selects and operates the switch corresponding to the symbol 11 of the device he or she wishes to operate from within the operation panel 40. .

In response to this operation, the corresponding device symbol 11 on the CRTIO blinks, and this blinking allows the operator to confirm that the selection of the device has been accepted by the monitoring system via the control computer 30, and to check the selected device. Operate the switch corresponding to the operation such as turning on or off.

Through this operation, an operation request is transmitted to the selected device in the field equipment 50 via the control computer 30, and actual operations such as turning on and off are performed.

(Problem to be Solved by the Invention) However, when performing a monitoring operation using the above system, the operator selects a device while alternately viewing both the operation panel 40 and the CRTIO, which are provided apart from each other. There is a problem that it is difficult to operate.

In particular, as the scale of the equipment to be monitored increases, the number of devices to be monitored and operated also increases, so operation using the operation panel not only deteriorates operability in normal times, but also makes it difficult to respond sufficiently when quick operations are required, such as in emergencies. become unable.

Furthermore, since it is necessary to provide the same number of selection switches on the operation panel 40 as there are devices to be operated, the operation panel 40 becomes large, and when the equipment to be monitored is expanded or changed, the number of selection switches in the operation panel 40 increases. It is necessary to add or change switches.

The present invention has been made in view of the above circumstances, and its purpose is to provide flexibility in the selection of target equipment using the operation panel, thereby improving operability for operators and making it possible to flexibly respond to expansions and changes of equipment. The object of the present invention is to provide a monitoring control device that can reasonably utilize a CRT or a graphic panel.

[Structure of the invention]

(Means and Effects for Solving the Problems) The supervisory control device according to the present invention has a display device that graphically displays a monitored object and displays operating devices therein in symbols.

The invention described in claim (2) uses a CRT as a display device, and a touch keyboard having a panel-shaped pressure-sensitive sensor and a key switch for operation commands is provided corresponding to the CRT, and the pressure-sensitive sensor is connected to the CRT. The device is characterized by selecting a device to be operated on a CRT according to the coordinates of a given point by touching it with a finger, and operating the selected device using a common operation command switch. be.

Next, the invention as claimed in claim (2) is based on the invention as claimed in claim (2) above, and further includes a range including a device to be operated on the CRT corresponding to the coordinates of a point given by touching the pressure-sensitive sensor with a finger. After specifying.

The feature is that the device to be operated is selected by touching the keyboard again.

The invention described in claim (2) uses a graphic panel as a display device, and corresponding to this graphic panel,
A touch keyboard having a panel-shaped pressure-sensitive sensor and a key switch for operation commands is provided, and includes equipment to be operated on a graphic panel in response to the coordinates of a point given by touching the pressure-sensitive sensor with a finger. After specifying the range, the device to be operated is selected by touching the keyboard again, and the selected device is operated using a common operation command switch.

Therefore, according to the present invention, any one of a plurality of symbols displayed on a CRT or a graphic panel is selected and blinked by a single-action or two-action touch operation on the touch panel of a touch-equipped operation panel. This system gives operation commands to the equipment corresponding to the blinking symbol, and the operator can perform operations while visually viewing only the CRT or graphic panel, improving operability. Furthermore, it is possible to improve operability when adding or changing monitoring targets. It is also possible to flexibly respond to expansions or changes in target equipment without changing the keyboard hardware.

(Example) Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a system configuration diagram of an embodiment of the present invention. In the figure, device symbols 11 indicating devices to be monitored by the system are displayed on the CRTIO as in the past, and these symbols 11 are lit in red, green, etc. by the display function 31.

That is, the control computer 30 inputs signals from the on-site electrical equipment 50 and displays the status on the CRTIO,
It accepts requests from the operation panel 20 and outputs outputs such as turning on/off to on-site equipment, and also collects information on the on-site equipment 50, edits its contents, and displays the information on the on-site equipment 50 via the display function 31. Equipment symbol 1 corresponds to the on/off status, etc.
1 lights up in red, green, etc.

With this system, the status of the on-site equipment is always displayed on the CRTIO, and this allows an operator who monitors the equipment to monitor the equipment from a monitoring room that is separate from the actual equipment.

In this case, the device is operated using the touch operation panel 40.

As shown in FIG. 2, a touch panel 41 and an operation switch 42 are attached to the touch operation panel 40.
When a finger touches the surface of the touch panel 41, movement command information is transmitted to the control computer 30 via the operation panel controller 20, and the symbol located closest to the point on the CRTIO corresponding to the touched point on the touch panel 41 is transmitted to the control computer 30 via the operation panel controller 20. 11 is blinking, and when the operation command switch 42 on the panel is operated in this state, the device corresponding to the currently blinking symbol 11 is selected and operated.

Therefore, when an operator wants to operate a certain device, he touches a point on the touch panel 41 that seems to correspond to the device he wants to operate, and if the symbol 11 that does not correspond to the desired device blinks, he touches the point on the touch panel 41 while looking at the CRTIO. After moving the touch point and confirming that the symbol 11 corresponding to the desired device has blinked, the operation command switch 42 is operated.

Through this operation, the operator's operation request is transmitted to the selected device in the field equipment 50 via the control computer 30, or a turn-off operation is performed.

In this case, the operation panel 40 with touch is the touch panel 4
The two-dimensional coordinates of the touched point are given as two numerical values to the operation panel controller 20 as output 1, and
On/off data is given to the operation panel controller 20 as the output of the operation command switch 42.

FIG. 3 shows a processing procedure performed by the operation panel controller 20 in response to a signal from the touch operation panel 40.

In FIG. 3, first, in step 101, a received signal is checked to determine whether it is an input from the touch panel 41 or an input from the operation command switch 42.

Next, in step 102, it is determined whether the received signal is due to an operation on the touch panel 41. If the received signal is due to an operation on the touch panel 41, the process proceeds to step 103; otherwise, the process branches to step 105.

In step 103, the coordinates of the touch given from the touch panel 41 are read, and the operation target device displayed at the position closest to the coordinates on the CRTIO is searched.First, in step 104, the selected object determined in step 103 is A signal for selecting a device is output to the control computer 30.

On the other hand, in step 105, the input signal is the selection command switch 4.
Out of 2, determine whether it is a switch that commands “on”, and if it is a switch that is “on”, step 1
If not, proceed to step 107.

In step 106, for the control computer 30,
The control computer 30 outputs a command signal for input ''' operation, and in response to this, the control computer 30 selects the PIO corresponding to the currently selected operation target device.
Outputs the "human" operation signal to the corresponding point (process input/output).

On the other hand, in step 107, among the selection command switches 42, "
It is determined whether the switch is for a switch that commands "off",
If the switch is "off", the process advances to step 108; otherwise, it is determined that no operation has been performed, and the process returns to step 101 to input the signal again.

In step 108, as in the case of step 106, a command signal for "off" operation is sent to the control computer 30, and in response to this, the control computer 30 outputs the PIO corresponding to the currently selected operation target device of the field equipment 50. Performs a ``cut'' operation output to the point.

The above process is repeated to select and operate the device to be operated.

In the arithmetic processing for obtaining the operation object with the shortest distance in step 103, an appropriate distance evaluation function is calculated for all the operation objects, and the one that gives the minimum value is determined as the operation object to be sought.

As a distance evaluation function, the coordinates of the touched point are expressed as (xt
d
=Cxt yn)"+ (Work t'/n)"
or d=l:ct-xnl+lyt-yn
l is used, and a decision is made to minimize it.

As a result, highly flexible monitoring control is possible by touch operations at arbitrary touch positions on the touch-equipped operation panel and operation operations of common operation switches.

FIG. 4 is a system configuration diagram of another embodiment of the present invention.

The only difference between this embodiment and the embodiment shown in FIG. 1 is that a device symbol 11 indicating a device to be monitored by the system is displayed on the CRTIO together with a selection area 12, so the parts are the same as the embodiment shown in FIG. will be described with the same reference numerals attached.

The control computer 30 inputs signals from the on-site electrical equipment 50 and displays its status on the CRTIO, accepts requests from the operation panel 20, and outputs outputs such as turning on/off the on-site equipment. Furthermore, the information on the field equipment 50 is collected, the contents are edited, and the equipment symbol 11 is displayed in red or red depending on the status of the field equipment 50, such as on/off, via the display function 31.
Light it up in green.

With this system, the status of the on-site equipment is always displayed on the CRTIO, and this allows an operator who monitors the equipment to monitor the equipment from a monitoring room that is separate from the actual equipment.

In this case, one device is operated using the touch operation panel 40A.

A touch panel and an operation switch (both not shown) are attached to the touch operation panel 40A, and when a finger touches the surface of the touch panel, area designation information is transmitted to the control computer 30 via the operation panel controller 20. , C corresponding to the touched point on the touch panel
An area of a certain size on RTIO is displayed as a selection area 12 in a frame on C:RT10.

As a next step, assuming that the selection area 12 on the CRTIO corresponds to the entire area of the touch panel, when you touch the surface of the touch panel with your finger, the operation panel controller 20
Coordinate designation information is transmitted to the control computer 30 via
CR corresponding to the touched coordinates on the touch panel 41
The corresponding symbol 11 on the selection area 12 on the TIO blinks, indicating that it is the 1 selection symbol.

Next, by operating either ON or OFF of the operation switch on the touch panel-equipped operation panel 40A, an ON or OFF output is performed for the on-site equipment corresponding to the selected symbol 11.

FIG. 5 shows a processing procedure performed by the operation panel controller 20 upon receiving the signal from the touch operation panel 40A.

In FIG. 5, first, in step 201, the received signal is checked and it is determined whether the received signal is input from the touch panel or from the operation command switch 42.

Next, in step 202, it is determined whether the received signal is due to an operation on the touch panel, and if the received signal is due to an operation on the touch panel, the process advances to step 203.

Otherwise, the process branches to step 205.

In step 203, it is determined whether the selection area 12 is before being displayed on the CRTIO based on the previous touch panel operation, and if the selection area 12 is before being displayed, it is determined that the received signal this time is a selection area designation. The process proceeds to step 204, and if not, the process proceeds to step 209.

In step 204, a request to display the selected area on the CRT is output to the control computer 30 in response to the received signal.

In step 209, the coordinates of the touch applied from the touch panel are read, and the device to be operated that is displayed at the position closest to the coordinates in the selection area 12 on the CRT 10 is searched, and then in step 210, the coordinates of the touch applied are read, and the device determined in step 209 is determined in step 210. The control computer 30 sends a signal to select the selected device.
Output for.

On the other hand, in step 205, it is determined whether the input signal is from a switch that commands 6 "people" among the selected command switches, and if it is from a switch that is "on", step 205 is performed.
If not, proceed to step 207.

In step 206, a command signal for an "input" operation is output to the control computer 30, and in response to this, the control computer 30 controls the corresponding PIO (process input/output) corresponding to the currently selected operation target device. Outputs the operation signal of "Pa input to point".

On the other hand, step 20? Now turn the selection command switch “off”
It is determined whether or not the switch is for a switch that commands the switch to turn off, and if it is for a switch for turning off the switch, the process proceeds to step 209;
If not, it is determined that no operation has been performed, and the process returns to step 201 to input a signal again.

In step 208, as in the case of step 206, a "cutting operation command signal" is sent to the control computer 30, and the control computer 30 receives this and outputs the PIO signal corresponding to the currently selected operation target device of the field equipment 50. ``Cut'' to the point of
Performs the operation output.

The above process is repeated to select and operate the equipment to be operated.

Note that in the selection area display request in step 204, a method such as specifying a rectangular area whose center of gravity is the coordinates of the touched point is used.

For example, the parameters for defining the region M, N (M, N〉
0, a constant value for each system), and calculate the coordinates of the touched point (t.

νt), 4 points (t-M, νt NL(x
t Ms yt+N)+ (r, t+M, yt+
N).

The selection area 12 can be a region connecting (t+M, yt-N) with a line segment.

In addition, in the arithmetic processing for obtaining the operation object with the shortest distance in step 209, an appropriate distance evaluation function is calculated for all the operation objects, and the one that gives the minimum value is determined as the operation object to be sought.

As a distance evaluation function, the coordinates of the touched point are expressed as (t +
yt), the coordinates of the operation target are (:Cn + νn), and d=(engine tyn)2+(xt yn)"
Or d=lxt-enginenl+I? t-ynl
is used, and a decision is made to minimize this.

As a result, highly flexible monitoring control is possible by touch operations at arbitrary touch positions on the touch-equipped operation panel and operation operations of common operation switches.

FIG. 6 is a system configuration diagram of still another embodiment of the present invention. This embodiment differs from the embodiment shown in FIG. 4 in that a graphic panel is used as a display device, and the other configurations are the same as in FIG. 4, so the same parts are given the same reference numerals. explain.

In FIG. 6, device symbols 11 indicating devices to be monitored by the system are displayed on the graphic panel IOA as in the conventional case, and these symbols 11 are lit in red, green, etc. by the display function 31.

That is, the control computer 30 inputs signals from the on-site electrical equipment 50 and displays the status on the graphic panel 10A, and also accepts requests from the operation panel 20 and controls the on-site equipment such as turning on and off. Outputs the information, further collects information on the field equipment 50, edits the contents, and displays the display function 3.
1, the equipment symbol 11 is lit in red, green, etc. in response to the on/off status of the field equipment 50.

With this arrangement, the status of the on-site equipment is always displayed on the graphic panel 10A, and this allows the operator who monitors the equipment to monitor the equipment from a monitoring room that is separate from the actual equipment.

In this case, the device is operated using the touch operation panel 40A.

A touch panel and an operation switch (both not shown) are attached to the touch operation panel 40A, and when a finger touches the surface of the touch panel, area designation information is transmitted to the control computer 30 via the operation panel controller 20. , an area of a certain size on the graphic panel 10A corresponding to the touched point on the touch panel is selected as the selection area 12 on the graphic panel IOA, and the device symbol therein is selected and displayed in the zero-order step. Assuming that the selection area 12 on the graphic panel IOA corresponds to the entire area of the touch panel 40A, when you touch the surface of the touch panel with your finger, coordinate designation information is transmitted to the control computer 30 via the operation panel controller 20, and the touch The corresponding symbol 11 in the selection area 12 on the graphic panel IOA corresponding to the coordinates on the touch panel blinks, indicating that it is the selected symbol. Next, by operating either the ON or OFF operation switch on the touch panel-equipped operation panel 40A, an ON or OFF output is performed for the on-site equipment corresponding to the selected symbol 11.

FIG. 7 shows a processing procedure performed by the operation panel controller 20 in response to a signal from the touch operation panel 40.

In FIG. 7, first, in step 301, a received signal is checked to identify whether it is an input from a touch panel or an operation command switch.

Next, in step 302, it is determined whether the received signal is due to an operation on the touch panel. If the received signal is due to an operation on the touch panel, the process proceeds to step 303; otherwise, the process branches to step 305.

In step 303, it is determined whether the selection area 12 has already been determined by the previous touch panel operation.1 If the selection area 12 has not yet been determined, it is assumed that the received signal this time is the selection area designation, and the process proceeds to step 304. , otherwise the process proceeds to step 305. In step 303, a request for selective display of symbols within the selection area of the graphic panel IOA is output to the control computer 30 in accordance with the received signal.

In step 305, the coordinates of the touch applied from the touch panel are read and the operation target device displayed at the position closest to the coordinates in the selection area 12 on the graphic panel 10A is searched. A signal for selecting the selected device determined in is output to the control computer 30.

On the other hand, in step 309, the selection command switch is turned off.
It is determined whether the switch is for a switch that commands "off", and if it is for a switch that is "off", the process proceeds to step 310;
If not, it is determined that no operation has been performed, and the process returns to step 301 to input a signal again.
