Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a man-machine interface device for a power system monitoring system installed at a power supply dispatching place or the like.

[0002]

2. Description of the Related Art A man-machine interface device of a power system monitoring system is generally composed of a plurality of control consoles equipped with one to three display devices (for example, CRT devices). Multiple operation buttons (usually 30 to 8
In addition to the number (0) installed, an alarm buzzer that sounds a signal from an electronic computer is often built in. Furthermore, there are examples in which the operation button is of a lighting type, and a system monitoring board, a voice output device, and the like are combined. Under such a structure, the operation button usually has the following two functions. (1) Screen display on CRT display device

Although the type and number of screens differ depending on the scale of the power system monitoring system, a typical screen is provided with a corresponding operation button, and when the operation button is pressed, the corresponding screen is displayed.
It is configured to be displayed on the RT display device. For example, when the "voltage abnormality" button is pressed, a screen showing a history of voltage abnormality is displayed. (2) Prevention of alarm confirmation

In response to the notification of the abnormality of the power system, the system idea that the computer continues to recognize the abnormality until the operator returns a confirmation response to the system, for example, even if the abnormality is resolved, It is strongly desired from the operational aspect.
Therefore, for example, when a voltage abnormality alarm is sounded, the operator presses the “voltage abnormality” button as a confirmation response, and the system stops the alarm accordingly. Needless to say, the operator is not allowed to check without knowing the details of the abnormality, but since the corresponding screen is displayed by pressing the operation button as described in (1) above,
The operator can obtain the necessary information. This method is 2
It is widely adopted because it is superior in that one simple function makes one operation flow.

[0005]

In recent years, an approach from the field of artificial intelligence has been prosperous for monitoring / controlling technology of electric power systems. This includes the problem of weighting alarms when abnormalities are detected, but now that stable supply of power is becoming more serious, the alarm concept of notifying the operator of even minor events is a system configuration. Is reflected in. In such a system, the alarm device sounds very frequently on a daily basis, and each time the operator presses the corresponding operation button as a confirmation response, detailed information is confirmed on the CRT screen. For the sake of convenience of explanation, in the conventional technique, the voltage abnormality is taken as an example, but in the actual power system monitoring system, the alarm device is often set to sound similarly when the opening / closing of the switch is detected.

When the operation button is pressed as a confirmation response, the screen displayed on the CRT display device until then is replaced with another new screen by pressing the button, and the operation of the operator until then is interrupted. .. Since such interruptions occur frequently as described above, the conventional configuration causes a drop in the operational efficiency of the operator. On the other hand, confirming the detailed information when an alarm is issued is also an essential task for the operator, so it was desired to carry out this while continuing the operation from before.

The present invention has been made in view of the above circumstances. It is possible to confirm detailed information when an alarm is issued, as in the prior art, while the operator continues a series of operations depending on the case. It is therefore an object of the present invention to provide a man-machine interface device having excellent operability by making it possible to confirm the alarm content when an alarm is issued.

[0008]

A display device, a plurality of operation buttons, an alarm device, a process interface device for inputting and outputting signals between the operation button and the alarm device and a computer, and the computer are connected to a power system. An alarm notification unit that sounds an alarm when an abnormality is detected, a full-screen display unit that newly outputs a screen indicating abnormality information of the power system to the display device by the operator pressing a predetermined operation button, and the like. Half-screen display means for outputting a small screen summarizing abnormal information of the electric power system by pressing the operation button of the above on a part of the screen currently displayed on the display device, full-screen display means and half-screen It is constituted by an alarm stopping means which is activated by both of the display means and stops the alarm device which is currently sounding.

[0009]

The alarm notifying means is activated when the electronic computer detects an abnormality in the power system, sounds an alarm device, and notifies the operator of the occurrence of the abnormality. When the operator presses the operation button for full screen display, the full screen display means is activated, after displaying the screen showing the abnormal information on the display device, the alarm stop means is activated,
The alarm stop means stops the alarm ringing. When the operator presses the operation button for half-screen display, the half-screen display means is activated, the screen currently displayed on the display device continues to be displayed, and after a small screen showing the error information is overlaid and displayed, The alarm stop means is activated, and the alarm stop means stops the alarm ringing.
