Abstract

PURPOSE:To display an emergency meassage (abnormality information, etc.) from the center, when a terminal is connected with the center, in an on-line system. CONSTITUTION:At the normal time, information from the center is stored in a buffer 10 and is displayed on a CRT1 through a display part 9. When abnormality occurs in the center, a telegram message receiving part 6 detects incoming of an emergency message by a detecting part EMS and displays 2 the incoming. In this case, the regular service is discontinued at a properly punctuated part (by a discontinuing signal K1), a save processing part 11 is started, and the detecting part EMS is cleared. The save processing part saves the contents and control information of the buffer 10 into a save memory 3, transfers a display data to the buffer 10 from the telegram message receiving part, and displays the emergency message on the CRT. When the emergency message processing is ended, an operator inputs a K2 signal. In this way, restore-processing 12 is started, and the system is reset to its previous state.

Description

[Detailed Description of the Invention] (1) Technical Field of the Invention Does the present invention provide a display screen connected to a center? The present invention relates to a control method for a terminal having a terminal.

(11) Conventional technology and problems Equipped with a large-scale computer system as a center, telephone lines, etc.? There has been an online system in which terminals located in various places operate via the internet. This terminal has a certain processor a
Press t to connect to the center and start all processing operations. Entering the state of connection with this sensor is called the start of the connection, and ending the state of connection is called the end of all the connections.

Conventionally, from the start of this session until the end of 1%, the center would send an emergency message. Even if I sent it, it would not be displayed on the display screen, so I would have been able to see the emergency message.

(Song) Purpose and Structure of the Invention The purpose of the present invention is to eliminate the above-mentioned drawbacks.This purpose is to detect all arrivals of emergency messages from the center and display the arrival of emergency messages on a part of the display screen of the terminal. A processing unit, based on an instruction signal when the arrival message is displayed, saves all the screen information and processing status being processed to temporary memory, and displays the arrival message on the entire display screen, a saving processing unit, while the arrival message is being displayed. Based on the signal instructed by -
This is achieved by a terminal control system that includes a restoration processing unit that displays the contents of time memory on the display screen and restores the entire internal state of the terminal.

6v+ Embodiments of the Invention FIG. 1 is a diagram showing an overview of the present invention. In the figure, l
The display screen of the ID terminal, 2 shows the arrival of an emergency message,
3 is a save memory. The operation is as follows.

■ If a request to send an emergency message is accepted during work after the session has started, the screen control unit will display one screen to that effect.
Displayed in the system usage area above (arrival display 2).

("2', ;I:M terminal operator can perform an output request action at any time after fully recognizing the arrival display of the emergency message.
NACTI pays out money.

- The screen control unit immediately performs a Read 'f3uffer (screen data extraction) of the currently displayed business screen, stores it in the evacuation memory 3, and proceeds to display the emergency message (interrupt display).

■ When the terminal operator has finished confirming the emergency message, he raises the Axilon ACT 2 indicating completion of confirmation.

■ By restoring the Buffer data stored in the evacuation memory 3, the display screen scheduler completely restores the work screen before the emergency message was displayed, allowing the interrupted work to be resumed immediately.

FIG. 2 shows an embodiment of the present invention. In the diagram, is the item with the same symbol as the previous one the same as the previous one? 4 is a center, 5 is a terminal, 6 is a message reception unit, 7 is a display control unit, 8 is a keyboard, 9 is a display unit, 1o is a buffer, 11 is an evacuation processing unit, 12 is a restoration processing unit, 13- 15 is an AND processing section, K1
, , is an instruction signal line from the keyboard 8 by the operator, and EMS is an emergency message arrival detection unit. Next, the entire operation will be explained.

The center 4 and the terminal 5 are connected via the circuit @16f:
After the session starts, information from the center of the display control unit 7 is stored in the buffer IO by sending and receiving a new code on the line 16, and the contents of the buffer 10 are displayed on the display screen 1 of the display unit 9. Then, the display control section 7 receives the signal from the keyboard 8, sends a message to the center as necessary, and continues until the end of the session.

When the session is being executed by the terminal after the session starts as described above, there is some abnormality at the center, for example, there is some kind of error in the message from the terminal 5, or the scheduled end of the period for sending the session from the center is approaching soon. When a situation arises in which the operator is to be notified, the message reception section 6 operates as follows: When the message reception section 6 detects all emergency messages arriving from the center (the reception section 6 attaches a flag indicating ``Emergency!'' and e to the message). The emergency message arrival detecting section EMI causes the display section 1 to display an arrival indication 2t.

In this state, it is of course possible to continue normal business operations.

Then, when the operator gives an instruction signal from the keyboard at a well-defined point, the evacuation processing section 11 is activated and the emergency message arrival detection section EMS is cleared. The save processing unit 11 saves the contents of the buffer 10 and the control information [to the save memory 3], and further transfers the display data from the message receiving unit to the buffer IO. Therefore, the display section 9 has a buffer 10
Since the contents are displayed on the full display screen 1, the operator can see the emergency message.

When the processing related to the emergency message is completed, the recovery processing unit 12 is activated in response to the operator's instruction No. 1J from the keyboard 8, and the contents of the buffer 10 and the internal state of the display control unit 7 are returned to the state before the emergency message was displayed. Return. Therefore, the operator can resume full operations.

(Vl Effects of the Invention According to the present invention, when an ICC emergency memo arrives during work on a terminal, the message can be viewed by interrupting the message at a well-defined point, and the message can then be easily returned to its original state.) The terminal returns to @ and the session ends.

Since there is no need to start the process, business processing efficiency is improved.
