Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to office processing using a man-machine device comprising a screen display device for displaying information on a controlled object and a command information input means for inputting commands from an operator. The present invention relates to the field of process industry, and particularly to an operator's console in the field of process instrumentation that monitors a huge number of screens in real time.

[Conventional technology]

Conventional operator's consoles store previously displayed screens as time-series screen information each time the screen is switched, and when redisplaying this time-series screen information, press 1 using the time-series screen call key.
The screen was redisplayed one by one and the target screen was taken. Additionally, if you switch the screen using a key other than the above-mentioned time-series screen call key while displaying a time-series screen, all the time-series screen information stored after the time-series screen that was being displayed before switching will be deleted. It was becoming like that. Therefore, in order to search for a desired screen from among the time-series screen information, the operator had to rely on his or her memory, and real-time operation was not possible. Further, no consideration was given to the fact that a plurality of pieces of the same screen information exist in the memory of time-series screen information, resulting in double storage and wasted memory.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology relies on the operator's memory when displaying the desired time-series screen information, and has the disadvantage of operability in that the stored time-series screen information must be searched for by re-displaying the information one screen at a time. In addition, there is a problem of performance deterioration in which multiple pieces of the same screen information exist in the stored time-series screen information, resulting in double storage and wasted memory. Ta.

An object of the present invention is to disclose an operator's console that accurately and quickly displays a target time-series screen without relying on the operator's memory, and does not waste memory.

[Means for solving problems]

The above purpose is to display screen information displayed on the CRT in chronological order in an operator's console that has a CRT as an information display device and a keyboard as a command information input means for inputting command information from the operator. It is equipped with a time-series screen information storage means for storing time-series screen information, and a means for displaying a screen code indicating the screen information stored in this storage means as a menu on a part of the CRT screen, and the screen code requested to be displayed from the keyboard is displayed in a time-series manner. If it corresponds to screen information stored in storage means,
This corresponding screen information is deleted from the storage means, screen information that is chronologically newer than this corresponding screen information is shifted in the past direction within the storage means, and the screen information of the screen that was being displayed at this time is This is achieved by storing the information in the latest storage area and displaying the contents of the corresponding screen information requested for display on the CRT screen.

[Operation] Since the chronological screen information storage means chronologically stores only the screen information of different screens displayed in the past, it is possible to store necessary screen information without using unnecessary memory. . In addition, the menu display means that uses a part of the screen displays the stored contents of the screen information storage means in chronological order, so when recalling a previously displayed screen, the operator does not have to rely on his memory and can accurately and quickly display the contents. It can be operated easily, making it easier to use.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3.

FIG. 1 is an overall configuration diagram of an embodiment of the present invention, in which a CRT viewer 1 has a menu display section 2 in its lower part that displays screen codes indicating screen information of chronological screens displayed in the past, and a keyboard. 3 has a selection key 4 that corresponds one-to-one positionally with the menu display section 2. This signal from the keyboard 3 is passed via the key code analysis section 5 to the display screen information judgment section 6 which judges the screen code of the switching screen commanded by the keyboard 3, and the CRT display is performed based on the screen code judged here. The control unit 7 calls the screen information file 8 and displays it on the CRT viewer 1.

Further, the screen code determined by the display screen information determination section 6 is also passed to the time-series screen information control section 9,
It is compared with the screen information stored in the time-series screen information storage unit 10, and if the same screen information corresponding to this screen code exists, the screen information stored in the time-series screen information storage unit 10 is deleted. Then, time-series screen information that is chronologically newer than this deleted screen information is shifted past by one screen information at a time. Furthermore, a pre-switching screen information storage unit 1 stores screen information of the screen that was displayed immediately before switching the screen information.
1 is stored in the latest screen information storage area of the time-series screen information storage section 10. The contents of this time-series screen information storage section 10 are displayed on the menu display section 2 via the CRT display control section 7, and there is a one-to-one correspondence between this interior and the plurality of selection keys 4.

FIG. 2 is a flowchart showing the above operation.

Further, FIG. 3 shows the internal movement of the time-series screen information storage section 10. When the system starts, the time-series screen information storage section 10 is completely cleared. As you switch screens, each time,
A time-series screen information storage unit 10 that stores screen information of displayed screens in a time-series screen information storage unit 10.
For example, when screen information existing in the screen information D is called, screen information D is deleted from the time-series screen information storage unit 10, and screen information C, B, and A that are newer in chronological order are deleted from the time-series screen information storage unit 10. The screen information is shifted forward one screen at a time, and the screen information X of the screen displayed before switching is stored in the latest area of the time-series screen information storage section 10.

FIG. 4 shows an example of screen information development.

〔Effect of the invention〕

According to the present invention, information on screens displayed in the past is displayed in a menu on the display screen in chronological order, and can be called up with a single action using a selection key on the keyboard, so that the operator can accurately and quickly call up chronological screens. effective. Furthermore, since the storage means that stores time-series screen information is controlled so that the same screen information does not exist, there is an effect that unnecessary memory is not used.
