JPS61262841A - System for updating automatically displayed information on display device - Google Patents

Abstract

PURPOSE:To display automatically updated information without imposing a burden on a computer system by providing a means transmitting a signal which requests the computer system to transmit information from each display device at every prescribed time and activating said means according to an indication from the computer system. CONSTITUTION:When a processor 6 receives the indication activating a timer 10 from the computer system 1 through an interface circuit 8, it activates the timer 10. After the prescribed period expires, the timer 10 transmits an interrupting signal to the processor 6. According to said signal, the processor 6 transmits the signal requiring the computer system 1 to transmit updated information on a file 2 through the interface circuit 8. When a person in charge inputs an instruction and correction information through a keyboard 9 in order to correct the information on the file 2, the processor 6 transmits the information to the computer system 1 through the interface circuit 8, and updates the information on the file 2.

Description

[Detailed Description of the Invention] [Summary] In an information system for executives, a display device is provided with means for requesting that the latest information of a computer system be sent at regular intervals, and management for the computer system to send updated information is provided. This also eliminates the need for executives to operate the display device.

[Industrial application field]

The present invention relates to an information system for executives, particularly for executives.

The present invention relates to an automatic display information update method for a display device that updates the display content of the display device at predetermined time intervals to display information required by the user.

In recent years, with the development of an information society, computer systems that provide various types of information to executives have come into use.

A plurality of display devices are connected to this computer system as terminal devices, and information required by each officer is displayed separately at all times.

The information displayed by this display device includes the schedule of each officer, and the person in charge may input changed information into the computer system to update the information.

In this case, it is desirable that the information displayed on the display device for the relevant officer be able to display this changed information without requiring any special operations.

[Conventional technology]

The second part is a block diagram showing an example of an information system for executives.

The computer system 1 has a file 2 that stores information to be provided to each officer, and display devices 3 to 5 are connected thereto for displaying information successively generated from this file 2 to each officer and person in charge.

The display devices 3 and 4 exclusively display information required by executives, and although they may have the same content, they may also have different content.

Here, for example, if there is a change in the schedule of a certain executive, the updated schedule is input from the display device 5 for the person in charge to the computer system 1, and the schedule portion of the relevant executive in the file 2 is changed.

This changed schedule can be displayed on the display device 3 by sending an update request to the computer system 1 from, for example, the display device 3 displaying the schedule of the certain executive, or by the computer system 1 automatically displaying the schedule on the display device 3 based on the updated information. was being updated.

[Problem that the invention seeks to solve]

- As shown in Section F, conventionally, an officer operates the display device to request information updates, or a computer system automatically updates the display contents on the display device based on the updated information, but the former does not update the information. There are problems in that it is unclear whether information is available or not, and it is cumbersome for executives to operate the display device.

In addition, the latter requires the computer system to manage the display contents of each display device, which displays different information for each officer, and there is a problem that the load on the computer system increases as the number of display devices increases.

In view of the above-mentioned problems, the present invention provides a means for sending out a signal requesting information transmission from each display device to a computer system at predetermined intervals, and starts the means in response to an instruction from the computer system. The purpose is to automatically display updated information without forcing the system.

[Means for solving problems]

FIG. 1 is a block diagram of a circuit showing one embodiment of the present invention.

6 is a processor that controls the entire display device; 7 is a RAM that stores information; 8 is an interface circuit that exchanges information with the computer system; and 9 is a keyboard that inputs information and commands.

10 is a timer that sends an interrupt signal to the processor 6;
1 is a ROM in which a program for instructing the operation of the processor 6 is stored; 12 is a display control circuit for displaying information in the RAM 7 on a display section 13; and 13 is a display section for displaying information.

The processor 6 is configured to start a timer IO in response to an instruction from the computer system, and request the computer system to send information at predetermined intervals using an interrupt signal from the timer 10.

[Effect]

With the above configuration, the processor 6 starts the timer 10 in response to an instruction from the computer system given from the interface circuit 8, and receives an interrupt signal from the timer 10 that is generated at a predetermined time interval to start the timer 10 via the interface circuit 8. You can request the system to send the latest information.

〔Example〕

In FIG. 1, a processor 6 reads a program stored in ROMI I and operates.

In response to a command input from the keyboard 9, the processor 6 runs through the interface circuit 8 to the computer system 1 shown in FIG.
request to send the specified information of file 2.

In accordance with the above request, the specified information of the file 2 is sent from the computer system 1 via the interface circuit 8.

The processor 6 temporarily stores this information in the RAM 7, reads it out, and displays it on the display section 13 via the display control circuit 12.

Here, when the processor 6 receives an instruction to start the timer 10 from the computer system 1 via the interface circuit 8, it starts the timer 10. The timer 10 sends an interrupt signal to the processor 6 when a predetermined period of time has elapsed.

In response to this interrupt signal, the processor 6 sends a signal requesting the sending of the latest information of the file 2 to the computer system 1 via the interface circuit 8.

When a person in charge inputs a command and modification information from the keyboard 9 in order to modify the information in the file 2, the processor 6 sends it to the computer system 1 via the interface circuit 8, and updates the information in the file 2.

〔Effect of the invention〕

As explained above, the present invention is capable of automatically displaying the latest information at predetermined intervals, and the computer system can send a timer activation signal to a display device that displays information that does not require updating. Since the information is not sent, no request for sending the latest information is generated, and it is possible to prevent the load on the computer system from increasing unnecessarily.
