Description

DETAILED DESCRIPTION OF THE INVENTION (Objective of the Invention) (Industrial Application Field) The present invention relates to various system monitoring devices for mining facilities, road facilities, tunnel facilities, factory facilities, energy facilities, plants, etc.

(Prior Art) A conventional system monitoring device is configured to display the state of system change, especially abnormal state, on a display device on an event-by-event basis.

(Problem to be Solved by the Invention) However, such conventional system monitoring devices have a configuration in which only one event is displayed. There are problems in that even if the abnormality is not high, an abnormality notification is made one by one, requiring excessive intervention by the operator, which may put mental pressure on the operator.

Furthermore, in recent years, it has become increasingly necessary to logically combine several signals as actual field signals to detect a change in state such as an abnormality.

In this case, it is necessary to provide a logic circuit in advance on the system side to be monitored or to incorporate a predetermined logic circuit into the monitoring device, but with conventional system monitoring devices, it is necessary to add a predetermined logic circuit. In addition, the contents of the logic circuit had to be changed in accordance with changes in logic.

It is an object of the present invention to provide a system monitoring device that can improve these problems and easily and reliably monitor the system by obtaining necessary and sufficient notifications.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention allows a system monitoring device to receive a plurality of status signals . . . a, b, A state signal input means 1 for inputting c..., a logical operation point file 2 for setting predetermined input signals a, b, c as logical operation targets A, B, C, and a manual input of the contents of the file 3. an editable logical operation point file editing means 3; the logical operation target A;
Regarding B and C, logical operation type A+B for system monitoring.

A logical operation type file 4 for setting B+C, etc., a logical operation type file editing means 5 capable of manually editing the contents of the file 4, and logical operation targets A and B set in the logical operation point file 2.

A signal a input to the state signal input means 1 regarding C
, b, 'c, and calculates predetermined monitoring data according to logic types A+B, B+C, etc. set in the logic operation type file 4.
and a monitoring data notification means 7 for notifying the monitoring data.

(Operation) In the present invention, the monitoring data logical operation means 6 refers to the logical operation point 1-file 2 and the logical operation type file 4, performs the logical operation on the input signals a, b, and c, and outputs the result. Notification is made by the monitoring data notification means 7.

Also, when it is necessary to register or change the monitoring targets A, B, C, you can edit the contents of the logical operation point file 2, and similarly, it is necessary to change the registration to the operation type A+B, B+C, etc. When this occurs, the contents of the logical operation type file 4 can be edited.

(Example) Hereinafter, the present invention will be described in detail using the accompanying drawings.

FIG. 2 is a block diagram of a system monitoring device showing an embodiment of the present invention.

In the figure, 8 is an electronic computer, and 9 is this electronic computer 8.
10 is a CRT display device, 11 is a keyboard for inputting necessary information and commands to the computer 8, and 12 is a data input device for inputting necessary monitoring data from equipment to be monitored at the site. be.

The electronic computer 8 incorporates the monitoring data logical operation means shown in FIG.

The storage device 9 stores a logic operation point file 9A and a logic calculation point file 9A that stores the contents of what kind of logic operations are to be performed. I! an operation type file 9B; an operation result storage file 9C for storing the results of logical operations from the file 9th;
Various types of processing necessary for receiving commands and data input from the keyboard 11, changing the registration of each file 9A and 9B, outputting to the CR1 display device 10, and processing actual logical operations, etc. A processing program (not shown) is stored therein.

FIG. 3 is a flowchart showing editing processing.

This process is started by a command from the keyboard 11.

In step 301, when the signal type to be displayed or edited (for example, a, b, c in the example shown in FIG. 1) is input, the logical operation point file 9A and logical operation type file 9B are searched in step 302, and the corresponding Signal calculation items (
point) and the calculation type are displayed on the CR1 display device 10.

Step 303 is for determining whether to display or edit, and in the case of confirmation display, an end code is input here, and the process ends without editing the conditions.

If an edit code is input in step 303, the process moves to step 304, where the input code selects either the i nest of the calculation point or the edit of the calculation type.

If the calculation point edit code is input, the process moves to step 305, and if the calculation type edit code is input, the process moves to step 307 via step 306.

Editing the calculation points in step 305 points to the signal types a, b, c shown in FIG. 1...A.

Symbol correspondence processing is performed to apply the symbols to B, C, and so on.

Editing the operation type in step 307 is performed in step 305.
Set logical conditions such as 10B, B+C, etc. to the point set in .

According to the editing flow shown in FIG. 2, each logical operation point and logical operation type for forming a logic circuit are registered in the logical operation point file 9A and the logical operation type file 9B, respectively.

FIG. 3 is a flowchart of logical operation processing performed by the electronic computer 8.

The process is activated based on a change in the state of a signal input to the data input device 12.

First, in step 401, a signal whose state has changed (for example, a
) related to a plurality of signals (e.g. a.

b, c), and in step 402, these signals (a, b) are retrieved from the logic operation point file 9A.

The points (A, B, C) corresponding to C) are taken out, and in step 403, the state (a, b, c) of each signal (a, b, c) is
For example, enter on, off).

Next, in step 404, the logical operation type (for example, A+
B, B+C), performs a logical operation at step 405, and stores the operation result at step 406.

Finally, the data stored in step 406 is transferred to CR7.
It is displayed on the display device 10. The display will be monitored by the operator.

As described above, in this example, the currently registered calculation points and calculation types are displayed on the CR7 display device 10 and checked, and then the logical calculation points and logical calculation types can be freely changed by operating the keyboard 11. Since it can be edited, conditions can be easily added or changed.

In addition, as a result, the condition-processed detection results are displayed on the CRT display device 11, so that the operator can observe the necessary and sufficient number of displays to determine whether mining facilities, road IM facilities, tunnel facilities, factory facilities, etc. Various systems such as energy equipment and plants can be easily and reliably monitored.

Note that the present invention is not limited to the above-mentioned embodiments, but may be implemented in other embodiments by making appropriate design changes.

〔Effect of the invention〕

As described above, according to the system monitoring device according to the present invention, necessary and sufficient notification can be obtained and system monitoring can be easily and reliably performed.
