Abstract

PURPOSE:To exactly recognize the contents of an event by speedily displaying the detailed contents of a picture selected corresponding to the contents of the event while using a CPU. CONSTITUTION:When a signal showing the generation of the event is outputted and transmitted from an equipment to be monitored to an I/O port circuit 1, a CPU 3 fetches the signal outputted from the I/O port circuit 1, judges the contents and prepares multi-picture data by accessing a ROM 4 and fetching data required for displaying a relative picture in one multi-picture based on these judged contents. In this case, the CPU 3 collects or prepares data required for displaying the contents as the respective pictures constituting the multi- picture, writes these data in a display memory circuit 6 and displays the multi- picture on a CRT 7. Next, a command to select one of small pictures displayed by the multi-picture is inputted by operating a keyboard 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a man-machine interface device used in computer systems, monitoring systems and the like.

[0002]

2. Description of the Related Art As a man-machine interface device used in a surveillance system or the like, a device for displaying information to be monitored using a CRT is conventionally known.

This man-machine interface device creates a screen to be displayed based on the information output from the device to be monitored and displays it on the CRT.
The contents displayed on the screen are scrolled based on an instruction from the keyboard, or the next display target screen is created and displayed on the CRT.

[0004]

However, in the above-mentioned conventional man-machine interface device,
Since only one screen can be displayed on the CRT, when an event occurs due to abnormality detection from the device to be monitored, the screen showing the event content can be displayed only in the preset priority order. Therefore, there is a problem that the operator cannot operate the keyboard to select a required screen depending on the situation.

In view of the above circumstances, the present invention can display an outline of an event when the event occurs, and can quickly display detailed contents of a screen selected according to the contents of the event. It is an object of the present invention to provide a man-machine interface device capable of accurately grasping the contents of an event.

[0006]

In order to achieve the above object, a man-machine interface device according to the present invention comprises:
Create a multi-screen creation unit that creates a multi-screen based on the content of the event and displays it on the screen, and a detailed screen that shows the detailed content of the selected screen among the small screens that make up the displayed multi-screen. Then, a detailed screen creating unit for displaying the screen instead of the multi-screen is provided.

[0007]

In the above configuration, after the multi-screen creating unit creates a multi-screen based on the content of the event and displays it, when any one of the small screens that compose this multi-screen is selected, the detailed screen is displayed. The creating unit creates a detailed screen showing the detailed contents of the small screen and displays it in place of the multi-screen.

1 is a block diagram showing an embodiment of a man-machine interface device according to the present invention.

The man-machine interface device shown in this figure includes an I / O port circuit 1, a keyboard 2, and a CPU.
3, ROM 4, RAM 5, display memory circuit 6,
When a signal indicating the occurrence of an event is output from a device to be monitored, which is equipped with a CRT 7, a multi-screen for displaying the contents of the event in a multifaceted manner is created in response to the signal, and this is displayed on the CRT 7. When the keyboard 2 is operated to select one small screen constituting the multi-screen, the detailed screen showing the detailed contents of the small screen is displayed on the CRT 7 to display the contents of the event. Specifically inform.

When a signal indicating an abnormal state (for example, a water pump failure) is output from the equipment to be monitored, the I / O port circuit 1 captures this signal and outputs the CP signal.
Supply to U3.

The keyboard 2 is provided with various keys such as a numeric keypad, character keys, and function keys.
When each of these keys is operated, a key signal corresponding to the operation content is generated and supplied to the CPU 3.

The ROM 4 stores a program for defining the operation of the CPU 3 and various constant data, and when a read command is supplied from the CPU 3,
The contents designated by this read command are read out and supplied to the CPU 3.

The RAM 5 is a portion used as a work area or the like of the CPU 3, and when a write command is supplied from the CPU 3, the data supplied together with the write command is stored in a designated place, and When a read command is supplied from the CPU 3, the data stored in the location designated by the read command is read and supplied to the CPU 3.

Further, the CPU 3 processes the signal output from the I / O port circuit 1 based on the program stored in the ROM 4 to create multi-screen data indicating the contents of the event and displays it in the display memory. Detailed screen data indicating detailed screen contents corresponding to a part of the multi-screen data is created in accordance with a selection command output from the keyboard 2 or supplied to the circuit 2, and the detailed screen data is created in the display memory circuit 6. To supply.

The display memory circuit 6 has a storage capacity corresponding to the screen capacity of the CRT 7, stores the multi-screen data and the detailed screen data supplied from the CPU 3, and periodically reads out the stored contents. CRT
Supply to 7.

The CRT 7 has a display capacity to some extent, and takes in the multi-screen data or the detailed screen data supplied from the display memory circuit 6 and displays the multi-screen or the detailed screen.

Next, the operation of this embodiment will be described with reference to the flow chart shown in FIG.

First, when a signal indicating the occurrence of an event is output from the device to be monitored and transmitted to the I / O port circuit 1 (step ST1), the CPU 3 outputs the signal from the I / O port circuit 1. The signal is fetched and the contents thereof are judged, and the ROM is judged based on the judgment contents.
4 is accessed to take in the data necessary for displaying the related screens in one multi-screen to create multi-screen data (steps ST2 and ST3).

In this case, the CPU 3 collects or creates data necessary for displaying the contents as shown in FIG. 3, for example, as the respective screens forming the multi-screen, and stores them in the display memory circuit 6. After writing, the multi-screen 10 shown in FIG. 4 is displayed on the CRT 7 (step ST4).

After that, the operator who sees the multi-screen 10 judges which small screen 13 is the screen that can grasp the contents of the event most accurately, and operates the keyboard 2 based on the contents of the judgment. The multi-screen 10
If a command for selecting any one of the small screens 13 displayed by is input (step ST5), the CPU 3
Accesses the ROM 4 and collects data necessary for creating a detailed screen corresponding to the screen selected by the command, or creates detailed screen data to create detailed screen data, which is displayed by the display memory circuit 6 Write to (step ST
6, ST7).

As a result, the detailed screen 12 of the small screen 13 selected by the multi screen 10 is displayed on the CRT 7 in place of the multi screen 10 as shown in FIG.
The details of the event are displayed in detail (step ST
8).

Thereafter, the keyboard 2 is operated, and the above-described processing is repeated until the processing regarding the event is completed (steps ST1 to ST9).

As described above, in this embodiment, when an event occurs, the contents of the event are displayed in a multifaceted manner on the multi-screen 10, and then the contents of the designated small screen 13 are displayed in detail. So, when an event occurs, you can display an overview of the event,
It is possible to quickly display the detailed content of the small screen 13 selected according to the content of the event, which allows the content of the event to be accurately grasped.

[0024]

As described above, according to the present invention, when an event occurs, an outline of the event can be displayed and the detailed content of the screen selected according to the content of the event can be quickly displayed. This makes it possible to accurately grasp the content of the event.
