Abstract

PURPOSE: To prevent the erroneous selection or operation of a device to be controlled in a remote control mode by displaying the image of a control panel of the device on a CRT screen and operating an operating part on the image by means of a pointing device. CONSTITUTION: When an operator selects the symbol 2 of a device to be controlled by means of a pointing device, the symbol 2 is displayed with blinking to inform the operator of that the device is selected as a remote control object device. Then the image 3 of a control panel is edited by an image storage means and an image display control means according to the state of the control object device. The image 3 is shown on the screen of a CRT display device by a CRT screen display means. The on/off operations are carried out by means of the pointing device, that is, a pointing device cursor 6 is set at an operating part 5 and shifted in the inward direction, for example, in the same way as an actual device. Then the device control command data are outputted to an input/output device by a data transmission means.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control operating method in a supervisory control system using a CRT display device, and is intended to prevent erroneous selection or erroneous operation of controlled equipment.

[0002]

2. Description of the Related Art In a supervisory control system using a conventional CRT display device, when performing remote control of a device, for example, a symbol of a device to be controlled is operated by an operation input device on a facility monitor control screen of the CRT display device. Alternatively, when a pointing device is used for selection, the name of the device and the on / off operation tag are displayed on the screen of the CRT display device. After confirming the validity of the device selection by the name of the device and the characters of the on / off operation tag, the operator further selects the on / off operation tag by using the operation input device or the pointing device.

[0003]

In the above-mentioned conventional method, since it relies heavily on the identification by characters, there is a tendency that it is difficult to notice an erroneous selection or erroneous operation of the equipment to be controlled. In addition, the conventional method performs remote control operation with the same procedure for any device regardless of how to operate the field device, so when an operator who is not familiar with field devices performs field operations in an emergency, , There was a lot of trouble. Therefore, it is an object of the present invention to prevent erroneous selection or erroneous operation of equipment in a remote control in a supervisory control system using a CRT display device.

[0004]

According to the present invention, in a supervisory control system using a CRT display device, an image image of an operation panel of a device to be controlled is displayed on a CRT screen during a remote control operation of the device, and the image image is displayed. The upper operation unit is operated using a pointing device.

[0005]

In the present invention, when the symbol of the device to be controlled is selected using the pointing device on the equipment monitoring control screen of the CRT display device, the image of the operation panel of the target device is displayed on the screen of the CRT display device. . The operator confirms the validity of the device selection by this image. Further, the operation parts such as switches and levers on the image are operated with a pointing device in the same manner as an actual device. Through the above operation, it is possible to train the operator who is not familiar with the field equipment on the field operation.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an example of a supervisory control system using a CRT display device of the present invention, and FIG. 2 is a flow chart showing internal processing relating to remote control of equipment in the data processing device 20 of FIG. Is an example of a facility monitoring control screen displayed on the CRT display device 11 of FIG. In FIG.
The status signals from the equipment are input / output devices 101, 10
2 ,. ． ． , 10n are converted into data, and are stored in the data processing device 20 as monitoring data information by the data transmission means 26 and the information storage means 25. Further, the data display control means 23 and the CRT screen display means 21 of the data processing device 20 are used to monitor the CRT as equipment state monitoring data.
It is displayed on the screen of the display device 11. It should be noted that this series of processing is repeatedly executed at a certain fixed cycle, and the latest state monitoring data is always displayed on the screen of the CRT display device 11.

Now, temporarily, the operator's operation input device 1
It is assumed that the equipment monitoring control screen 1 called “electric equipment” shown in FIG. 3 is displayed on the CRT display device 11 by the operation of 2. When the operator uses the pointing device 13 to select the device symbol 2 corresponding to the "switch B", the display of the device symbol 2 blinks and notifies the operator that the device has been selected as the remote control target device. To do. Further, the image image storage unit 24 and the image image display control unit 22 edit the image image 3 of the operation panel according to the state of the controlled device, and the CRT is displayed.
It is displayed on the screen of the CRT display device 11 by the screen display means 21. In the image image 3 of the operation panel, the name of the device, the state symbol 4 showing the state of the device, and the operation unit 5 for performing the control operation are displayed. The state symbol 4 is lit only on the off side, indicating that the "switch B" is off.

The on / off operation is performed by using the pointing device 13 to move the pointing device cursor 6 to the operation unit 5 and moving it in, for example, the insertion direction (arrow direction) like an actual device. The image 3 of the operation panel is re-edited and re-displayed according to the movement of the pointing device cursor 6, and the display of the operation unit 5 is also changed to the on-state position as in the case of an actual device. Here, the device control command data is transmitted by the data transmission means 26 to the input / output device 1.
It is output to 02. When the "switch B" is actually turned on at the site, the monitoring data information is updated, and the image image 3 on the operation panel is further edited and displayed again. The state symbol 4 changes its display so that the off side is off and the on side is lit, and notifies the operator that the controlled device is in the on state.

[0009]

As described above, according to the present invention, in the supervisory control system using the CRT display device, by making the CRT display and the operating method at the time of remote control closer to the operational feeling of the field device, the device is erroneously selected. Alternatively, an erroneous operation can be prevented, and a training function for on-site operation can be added to the supervisory control system.
