Abstract

PURPOSE:To autonomically indicate the object to be monitored where the most serious fault occurs when faults continuously occur at a plurality of objects to be monitored by displaying the content of a screen memory containing objects to be monitored, the faults of which are the highest in level among the faults of the objects to be monitored. CONSTITUTION:A screen controlling memory is constituted of a register R2 for storing screen numbers at the time of normal mode, register R1 for storing screen numbers at the time of fault mode, and fault level storing register R3. The register R3 stores fault levels indicating the priority order for fault indication against each symbol mark stored in all screen memories G1-Gn. When faults occur, screen numbers containing the symbol mark of the faults are set in the register R1 and the fault levels of the fault symbol marks are read out from the register R3, and then, the screens are arranged in the order of the fault indicating priority from the screen containing the symbol mark of the highest fault level. Then the picture containing the highest fault level is displayed on a display 8.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of application on aluminum industrial beams) This invention relates to a supervisory control device used in a relatively large-scale system such as an electric power system. (b) Prior art In this type of supervisory control device, Normally, a single display is configured so that multiple screens can be switched and displayed.Each screen includes a system diagram that includes one or more monitoring targets, and each monitoring target can be easily viewed by the operator. It is designed to be displayed as a symbol mark.In such monitoring and control equipment, a screen memory with a predetermined number or an arbitrarily selected screen memory is displayed on the display during normal conditions. However, when a failure occurs in a certain monitoring target, the screen memory that includes the monitoring target is set as the failure screen memory and is forced to be displayed on the display.This control method is called the pop-up display method.

With conventional supervisory control equipment, when a failure occurs in a certain monitoring target, the pop-up display system automatically switches the display target screen memory to the failure screen memory and immediately informs the operator of the monitoring target where the failure has occurred. That's what I was doing.

(C1 Problem to be Solved by the Invention) However, in the conventional monitoring control device described above, when a failure occurs in a certain monitored object, the screen memory containing that monitored object is switched to, and then the screen memory that includes that monitored object is switched to. When a failure occurs, the screen memory that includes the monitoring target related to the later failure will be retained until the screen memory related to the previous failure is removed from the display state. For example, as shown in Fig. 4, when a failure occurs in the monitoring target corresponding to the symbol mark A1 in the screen memory G1, a screen memo is displayed on the display screen. IJ G 1 is displayed and the symbol mark A1 flashes, but if a failure occurs later in the monitoring target of the symbol mark B1 in the screen memory G2, the display screen still maintains the display state of the screen memory G1. , the screen memory G2 is waiting for display.In this case, if A1 is more important than 81 as a monitoring target, there is no problem in display, but B1 is more important than A1.
If it is more important than B1, B1 is in a standby state, which is not preferable.

In other words, in conventional monitoring and control equipment, when failures occur in two or more monitoring targets one after another, and a more important monitoring target fails later, the screen containing the more important monitoring target There was a drawback that it was not possible to perform pop-up display of memory.

The purpose of this invention is to assign a failure level to all monitoring targets, so that when failures occur in multiple monitoring targets consecutively, it is possible to prioritize the failure screen memory. It is an object of the present invention to provide a monitoring control device that enables pop-up display of a screen memory containing a more important monitoring target even in the above-mentioned case.

(Means for Solving Problem d1) This invention selects one screen memory from a plurality of screen memories that store symbol marks to be monitored in groups and a previous screen memory and displays it on a display screen. a display unit, a means for storing a failure level indicating a failure display priority of a monitored target corresponding to each mark for each symbol mark stored in the full-screen memory, and a means for storing a failure level representing a failure display priority of a monitored target corresponding to each mark; When there is only one faulty screen memory, the faulty screen memory is displayed, and when there are multiple faulty screen memories, the symbol mark stored in each memory is also set as a faulty screen memory. The present invention is characterized by comprising a failure display control means for displaying a failure screen memory including a level symbol mark.

(e) Effect In the monitoring system f'ill device according to the present invention, when a failure occurs, the screen memory that includes the failed monitoring target is set as the failure screen memory, and if there is only one failure screen memory, , its fault screen memory will be displayed.

On the other hand, when there are a plurality of failure screen memories, the symbol marks stored in each memory are inscribed to display failure screen memories that include symbol marks with a high failure level. Therefore, when a failure occurs in a plurality of monitored objects in succession, the screen memory that includes the monitored object with the highest failure display priority among them is displayed in a pop-up manner. For example, as shown in Fig. 3, when a failure occurs in the symbol mark A1 for the first time, the screen memory containing the symbol mark A1 is set as the failure screen memory and is displayed pop-up, but then the screen memory G2 is displayed in tn. When a failure occurs in symbol mark B1, the level of failure in A1 and 81 is determined at that time. , and when the failure level of B1 is higher than the failure level of A1, the failure screen memory containing B1 is popped up and displayed.

(f) Embodiment FIG. 1 is a block diagram of a supervisory control device according to an embodiment of the present invention.

The control unit l includes an input operation unit 22, a communication control unit 3. R0M
4. RAM5 is connected, and the memory for screen control further includes a register R2 that stores the screen number (screen #) in the normal mode, and a register R that stores the screen number in the failure mode.
1, and a fault level storage register R3. Further, a screen memory 6 consisting of n screen memories and a display control section 7 are connected to the control section 1. A display 8 is connected to the display control section 7 .

The failure level storage register R3 stores the failure level of each symbol mark stored in all the screen memories G1 to Gn. More specifically, for each symbol mark stored in the full-screen memory, a failure level representing the failure display priority of the monitoring target corresponding to each mark is stored. The normal mode screen number register R2 stores the screen memory number to be displayed in a normal state where no failure occurs. The contents of this register R2 are set to a predetermined initial value after power is turned on, but can be changed to any value by manual operation on the input operation section. The failure mode screen number register R1 stores the number of the failure screen memory that includes the symbol mark associated with the failure when a failure occurs. This register R1 is composed of a plurality of register sections, and each register is arranged in order of priority. The register with the highest priority is level O, followed by levels 1. It goes down to level 2... This prioritization work is performed by a sorting procedure as described below.

The screen memory 6 is composed of n screen memories G1 to Gn, and each screen memory stores symbol marks to be monitored for each group.

For example, in the screen memory G1, Al, A2 . The symbol mark of A3 is stored, and the screen memory G2 stores the symbol mark of B1, B2 . B
In general, these symbol marks are stored together with a system diagram and the like. The control unit 1 selects the screen memory having the screen number stored in the register R2 in the normal mode where no failure has occurred. Further, when the screen number of the failure mode is set in the register R1, the screen memory having the screen number stored in the highest level register section in the register R1 is selected.

The screen memory selected in this way is sent to the display control section 7 and displayed on the display screen of the display 8.

Note that the ROM 4 stores the operating procedures of the control unit 1, etc.
The communication control section 3 exchanges data with a monitoring target control section (not shown) through a plurality of communication channels.

FIG. 2 is a flowchart showing the general operation of the control section 1. As shown in FIG.

When the power is turned on, the normal mode screen number register R2
An initial value, that is, a predetermined screen memory number is stored in . When no failure occurs, the process progresses from n1 to n4,
At B4, it is determined whether data exists in register R1, but in normal mode, there is no data in register R1, so the process advances to B6, where the screen memory number stored in register R2 is selected and displayed. Control unit 7
send to In this way, the screen set as the initial value is displayed on the display screen of the display device 8.

On the other hand, when a failure occurs in a certain monitoring target, the process proceeds from n1 to n2, and here the screen memory number containing the failure symbol mark is set in register R1. Next, a sorting operation is performed in B3. In this sorting operation, the m screen numbers stored in the register R1 are arranged in descending order of level. In other words, when multiple fault screen memory numbers are stored, first, search the register R3 for a symbol mark with a high level of inscription of the faulty symbol mark in those fault screen memories, and select the symbol mark with the highest level. The number (screen number) of the deceased screen memory containing the symbol mark is set in the level 0 register section. Next, a high-level symbol mark corresponding to the faulty symbol mark is searched from the register R3, and the fault screen memory containing the symbol mark is set as a level 1 fault screen memory. In this way, in the register R1, the numbers of the failed screen memories are sequentially rearranged starting from level O. Note that if there is only one failed screen memory, the sorting operation of B3 is not performed. Next, in n4, it is determined whether there is a faulty screen memory number in the register R1, and if there is, the process proceeds to n5, selects the screen memory with the highest level in the register R1, and transfers that screen memory to the display control unit 7. hand over.

As mentioned above, by sorting in n3, even if multiple failures occur one after another, the failure screen memory that stores the symbol mark (monitoring target) with the highest failure level among them will be displayed in a pop-up manner. be able to.

The failure display control means of the present invention is indicated by n3 to n in FIG.
5 is compatible.

(g) Effects of the Invention According to the invention as described above, a failure level is given to each monitoring target in advance, and when a failure occurs in multiple monitoring targets in succession, the failure level of those monitoring targets is Because the system determines whether the failure level is high or low and always displays the screen memory that includes the monitoring target with the highest failure level, automatic Monitored targets with particularly important failures will be displayed pop-up.
