Abstract

PURPOSE:To simplify the operation of the maintenance personnel by generating a state change display picture automatically at the detection of a state change, displaying the content of plural state change items in a print image and selecting one of displayed state change items. CONSTITUTION:In the multi-window system, figure (a) shows a picture for normal monitor and plural windows are opened simultaneously by the operation for the monitoring. When any state change takes places, a state change display picture is automatically generated and state change items are displayed in print image as shown in figure (b). When one of the displayed state change items is selected, a relating detailed picture is displayed as shown in figure (c). Thus, the operation by the maintenance personnel is reduced and quick countermeasure on emergency is attained.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement of a centralized monitoring and control device using a CRT screen, and particularly to a system for notifying a maintenance person of changes in its status.

(Prior Art) Conventionally, in this type of state change display method, when a large number of state changes occur, only a total display indicating that a state change has occurred is displayed, and a monitoring screen including the state change items is displayed by another operation. ? It was impossible to determine what had occurred unless it occurred, and maintenance personnel had to perform many operations before finding a monitoring item that was not truly checked.

(Problems to be Solved by the Invention) In the conventional status change display method described above, the items and contents of status changes cannot be confirmed at a glance, and maintenance personnel have to perform many operations in order to know the contents of monitoring items that are not truly confirmed. This has the disadvantage of slow response to failures.

An object of the present invention is to automatically generate a status change display screen when a status change is detected, display the contents of a plurality of status change items as printed images, and select one of the displayed status change items. Another object of the present invention is to provide a state change display method that eliminates the above drawbacks and is configured to simplify operations for maintenance personnel.

(Means for Solving the Problems) The state change display method according to the present invention includes a first display means for automatically displaying a plurality of corresponding items as printed images at the same time when a state change is detected; and a second diagonal display means for displaying a related detail screen of display items by selecting one of the display items.

(Implementation row) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is an explanatory diagram showing an example of a state change display screen in an embodiment of the state change display method according to the present invention.

The status change display screen displays status change items individually as printed images, and the display contents include a number (No) indicating the order of occurrence, the time of occurrence of the status change, route name, station name, system,
and attributes related to monitoring items such as item names, monitoring item statuses (ALARMl and NORMAL), and A
This is the duration of the LARM state, and all states of the state change items can be checked just on the state change display screen.

The f4z diagram is an explanatory diagram showing the transition of screen display before and after the occurrence of a state change in the present invention.

In FIG. 2, (a) shows a screen display during normal monitoring, (b) shows a screen display when a state change is detected, and (C) shows a screen display when a state change item is selected.

In FIG. 2, a multi-window system is assumed, and in (a), multiple windows are simultaneously opened and monitored by operation on the screen during normal monitoring. When a state change occurs, a state change display screen is automatically generated and displays the state change items in (b).

When the displayed status change item is selected, a related details screen is displayed as shown in (C).

(Effects of the Invention) As explained above, the present invention automatically generates a state change display screen when a state changes, displays the contents of a plurality of legal change items as a printed image, and displays the displayed state change. By selecting one of the items, the maintainer can immediately know the occurrence and content of the status change, and can also directly display the related details screen, so that the maintenance personnel can immediately check the occurrence and contents of the status change, and can directly display the related details screen. This has the advantage that positioning and confirmation of the failure status of the entire system can be performed with a minimum of operations. This has the effect of reducing the number of operations required by maintenance personnel and enabling prompt response in the event of an emergency.
