Abstract

PURPOSE:To monitor faults in many components with a small-scale apparatus by updating surface images even if a component corresponding to fault data are not displayed, and performing the display to which a significance is imparted corresponding to the content of the fault of said component. CONSTITUTION:At first, a central processing unit 21 forms image source information, fault information, etc., in accordance with a batch processing program beforehand. They are stored in an image source information file 4, a fault information file 5 and an image display information file 6. When, the fault data for every component are supplied from a radar system in on-line state, the data are aligned and stored in a fault data file 1. Then, a monitoring person operates a keyboard 3 and selects the image. The file matching the kind of the specified image is read out of the file 6 and displayed on a graphic display 7. The displayed fault data are read out of the file 1, and the significance of the content of the fault is imparted to the component on the displayed image in correspondence with the fault data. When a specified indication, e.g., a color, is applied for every content to which the significance is imparted, the location of the fault can be determined.

Description

[Detailed description of the invention] [Industrial application field]

This invention relates to the monitoring of failed blocks in a large-scale system such as a radar device, which is constructed by distributing many components, and in particular displays a failed block diagram screen for centrally monitoring failed blocks. It is related to the method.

[Conventional technology]

In large-scale systems constructed by distributing many components, such as radar equipment,
It is important to quickly and accurately identify faulty blocks. In such a large-scale system in which many components are distributed, monitoring efficiency is improved by centrally monitoring the system. Here, the conventional centralized monitoring of failed blocks at a central location is achieved by dividing a large-scale system into blocks by function or arrangement, and arranging a large number of display elements corresponding to each block. It constitutes a centralized monitoring device. Therefore, a supervisor monitors a large-scale system for failure by visually determining the lighting status of a large number of display elements. FIG. 5 is a block diagram for explaining a conventional failure block display method for monitoring failure blocks of a radar device as a large-scale system. In the figure, 8 is a failure data manual buffer circuit that takes in predetermined block unit failure data (BIT data) supplied from a radar device (not shown) as a non-monitoring system; This is a display processing circuit that drives display elements constituted by lamps or liquid crystals in the failure display panels 10a to 10c corresponding to the failure data in accordance with the failure data supplied by the failure data. Next, the operation will be explained. In the system failure monitoring device configured as described above, when a radar device (not shown) as a non-monitoring system fails for some reason, failure data indicating the block in which the failure has occurred is sent. This failure data is then taken in by the failure data manual buffer circuit 8 and supplied to the display processing circuit 9. In the display processing circuit 9, by identifying the contents of the failure data according to predetermined conditions, the failure display panel 10a that includes the display element in charge of the failure block indicated by the failure data is first identified.
Select ~10c. Then, by lighting the display element indicating the failed block corresponding to the failure data stored in the selected failure display panel 10a to 10c, the failed block is displayed. Therefore, a supervisor can constantly monitor a large number of display elements housed in the failure display panels 10a to 10c, and visually find a display element whose display has changed to a failure state, thereby monitoring failures in a large-scale system. − becomes.

[Problem to be solved by the invention]

Conventional failure monitoring for systems has been performed as described above, so if you apply it to failure monitoring of a large-scale system with a large number of components and display the failure status of each component in detail, failure data It is necessary to provide display elements corresponding to the number of display elements, which increases the size of the failure display panel and requires a large space to accommodate this device. Furthermore, as the failure display panel becomes larger, the number of monitors who visually monitor the failure display panel must be increased. Furthermore, when the system configuration and monitoring contents are changed, there is a problem that the hardware of the failure monitoring system must be changed accordingly. This invention was made to solve the above-mentioned problems, and although it is a small-scale device, it is possible to centrally monitor failures of a large number of components in detail, and the system configuration can be The object of the present invention is to provide a failure block diagram screen display method that can easily respond to changes in the system and monitoring contents by simply changing the software without changing the hardware configuration.

[Means to solve the problem]

In the failure block diagram screen display method according to the present invention, each time failure data is supplied from the monitored system, a central processing unit performs software processing to assign meanings to the components displayed on the graphic display according to the details of the failure. If the component corresponding to the failure data is not displayed, the display screen is updated so that the screen that includes the component is displayed, and the corresponding component is displayed according to the failure details. The corresponding meaning is what causes the display to take place.

[Effect]

The failure block diagram screen display method according to the present invention displays the corresponding components on the display screen with meaning based on the failure data representing the failed component, and if there is no corresponding component on the current display screen. In some cases, the display screen is updated, so the monitor only needs to visually monitor the contents of one display, making it easy and detailed to monitor a large system made up of a large number of components. You can do it. Additionally, since the processing is done by software, it becomes easier to respond to changes in components and monitoring content. Furthermore, even if the number of components to be monitored further increases, the number of updated screens will only increase, and the space will not increase at all.
