It is a block diagram showing.

In this embodiment, when the data of each device transmitted from the remote monitoring and control device to the failure statistics data display device is stored, input signals are grouped in advance and associated with a signal which is abnormal or malfunctioning. Signals are defined as one grouped group, and when one of the signal values belonging to this group becomes abnormal or faulty, the time series data of the signal values belonging to this group are automatically displayed, and in what process The data is used to inform the operator of whether an abnormality or a failure has occurred, and to use the data for performing the abnormality or failure analysis.

First, the overall configuration of the supervisory control system will be described. In FIG. 2, a CPU 1 constitutes a central processing unit for executing various kinds of arithmetic processing, and the CPU 1 includes an auxiliary storage device 2 formed of a magnetic disk or the like for storing various data, a ROM or a RAM. CR used for editing the formed memory 3, data display, table, etc.
T display device 4, key input keyboard 5, and CRT
A light pen or a mouse 6 used for selecting symbols or measured values displayed on the display device 4 is connected, and these constitute a failure statistical data display device 10 of the present embodiment.

On the other hand, a plurality of remote monitoring and control devices 7 (7 _{1 to} 7 _{n in the} figure) for monitoring and controlling remote devices are provided, and data signals from these remote monitoring and control devices 7 are provided. Is sent to the LAN 9 through the slave station side transmission device 8 (in the figure, there are 8 ₁ to 8 _n corresponding to the distant monitoring control devices 7 _{1 to} 7 _n ), and the failure statistical data display device 10 is sent via this LAN 9. Data is transmitted to. A master station side transmission device 11 is provided between the failure statistical data display device 10 and the LAN 9.

As shown in FIG. 1, the failure statistic data display device 10 fetches a transmission signal from the distant monitoring control device 7 via the LAN 9 and the master station side transmission device 11 and sends various commands to the LAN 9 and the LAN 9 as shown in FIG. An input / output unit 12 for outputting to the distant monitoring control device 7 via the slave station side transmission device 8.
And an abnormality detection unit 13 for detecting an abnormality in the input signal taken in by the input / output unit 12, an input signal storage unit 14 for storing the input signal taken in by the input / output unit 12, and a group of input signals related to each other in advance.

And a display processing section 17 for displaying.

FIG. 3 shows an example of a screen configuration for selecting and registering a signal to be grouped as a grouping signal in advance and deleting the registered grouping signal.

For example, when registering a grouping signal on a single display screen such as an electric room, after selecting the "grouping signal registration" mode with the light pen or the mouse 6, the symbol or voltage shown on the screen is displayed. If you select the measured value shown as a value or current value,
The signal name is registered as a grouping signal. When deleting a signal registered as a grouping signal, it is deleted by selecting the “grouping signal deletion” mode and then selecting the signal name registered as a grouping signal. It is possible to display another screen by selecting the "next screen" mode or the "previous screen" mode shown on the screen, and the signal of the different screen can be registered as a grouping signal.

FIG. 4 shows a screen displayed when actually grouping the signals registered as the grouping signals as described above. When registering grouping, after selecting the "group registration" mode, the group name is entered from the keyboard 5 to register the grouping signal. For grouping signal registration, refer to "Grouping signal registration".
After the mode is selected, the signal name is selected from those registered as the grouping signal, whereby the grouping operation is completed. The grouped signal names are stored in the grouping signal registration file 16. Further, the grouping signal is deleted by selecting the "grouping signal deletion" mode and then selecting the signal name.

To delete a group registered as a group, after selecting the "group deletion" mode,
This is done by selecting the group name registered as the grouping.

As described above, when the abnormality detection unit 13 detects an abnormality in the input signal in the state where the input signals are grouped, the group related to the input signal in which the abnormality is detected by the display processing unit 17 is detected. The internal signal is searched from the grouping signal registration file 16, the searched signal is extracted from the signal storage unit 14, and these trend graphs are created.

FIG. 5 shows a display example when time series data of the signal values of this group is automatically displayed when any one of the grouped signal values becomes abnormal or malfunctions.

For example, when an abnormality occurs in the signal value of the signal name a, the signal name b, the signal name c and the signal name d registered in the group name A to which the signal name a belongs.
Each time series data of the signal value is automatically displayed, which is useful for operator's abnormality or failure analysis.

If another abnormality or failure occurs at the same time or while the operator is analyzing the abnormal data, the abnormal data that has occurred is queued as an operator unconfirmed state, and the operator waits for analysis. .
