JPS62221720A - Control system for terminal local picture - Google Patents

Abstract

PURPOSE:To reduce the processing load of a host computer as well as the line availability of a network and to improve the picture display speed, by increasing the local pictures stored at a terminal. CONSTITUTION:A picture storing part 2 stores the local pictures and the storage of pictures is divided into 26 files (A-Z) according to the ID of pictures. Each file consists of 256 pictures. An execution key is pushed when data are supplied through a keyboard with operation of keys. Then the input data are sent to a host computer and processed there and the corresponding picture number and data are sent to a terminal. A common picture control part 4 calls the corresponding picture out of the part 2 via a picture reading control part 3 and put on the data for display at a picture display part 5. When the picture is changed by the host computer, the changed picture is transferred when connection is secured with the host computer and stored in the part 2 via a picture writing control part 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a terminal local screen control method for a double-sided terminal used in a large-scale online data registration/inquiry system.

[Conventional technology]

Like the contract management system at an insurance company, terminal devices are provided in each department and branch office, and these terminal devices are connected to a host computer at a center to perform contract management operations. In such a system, an initial screen for inquiry processing, etc. is displayed from the computer to the center's host 1 on terminals capable of displaying screens in each division and branch office, input is made on that screen, data is transmitted, and the processing results are sent to the host computer. A common method was to combine and display screen information and data from the computer. Furthermore, even in systems that use terminal local screens, the limit on the number of local screens is 256 screens [files, etc.], making it impossible to control all business operations as terminal local screen files.

[Problem that the invention seeks to solve]

By the way, according to this method of displaying the initial screen from the host computer at the center, the larger the system becomes, the easier it becomes to display the initial screen from the host computer.
This reduces the processing power of the computer and increases the line utilization rate of the network, resulting in a decrease in the speed of initial screen display. In particular, when using a packet-switched network as the network, one initial screen display can display 1 upstream packet (128 characters or less) and 20 downstream packets (250 characters or less).
0 characters), the line usage charges will also increase. Furthermore, even in systems that use terminal local screens, the number of screens is limited (256 screens per file, etc.) and the readout method is centered on center instructions, so the above problems could not be completely solved. provides a control method that solves the above problem by increasing the amount of local screen storage at the terminal.

[Means for solving problems]

The present invention includes a terminal controller and a terminal device,
A terminal local screen that reads the corresponding screen on the terminal controller based on a local screen read request from the terminal operator and displays it on the terminal device, and writes/reads it on the terminal controller based on the local screen write/read request from the host computer. In the control method, means for writing a screen based on a local screen writing request from a host computer, a screen storage file for storing the screen, and a reading means for reading the screen stored in the screen storage file;
This is a terminal local screen control system characterized by having a screen display means for visually displaying a read screen, and an input means for inputting a screen number etc. for reading the local screen from a terminal operator.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a diagram showing the configuration of an embodiment of the present invention. Part 5
and a keyboard 6. Using Figure 1,
The functions of each part will be explained. The screen writing control section 1 classifies and stores screens by screen number in the screen storage section 2 according to a screen writing instruction from the host computer of the center.

The screen storage unit 2 stores local screens. The storage is divided into 26 files from 'A' to 2' depending on the screen ID. One file consists of 256 screens.

Therefore, up to 26 x 256 (=6656) screens can be stored.

The screen reading control unit 3 reads the screen storage unit 2 according to instructions from the host computer and instructions from the terminal operator.
The corresponding screen is read out from the screen and this screen data is sent to the screen display section 5.

The screen common control unit 4 transmits instructions such as screen writing/reading and display to the terminal from the host to each control unit 1.3.5, and manages the entire local screen control unit in the TC (terminal controller).

The screen display unit 5 superimposes and displays the read local screen and data from the host in response to a screen call from the host, and also displays the screen read locally in the terminal in accordance with instructions from the terminal operator. indicate.

In addition to inputting data from the terminal operator 1 note, the keyboard 6 issues a command to display the local screen by pressing a PF (program function) key that corresponds to the local screen, and also displays the local screen by directly inputting the screen number. Issue a command to call and display.

Next, the operation will be explained based on FIGS. 1 to 3.

■As shown in Figure 2, there has been a table corresponding to the PF key in the past, but the format of this table has not been changed and the screen ID section has been classified as ``A'' to 1Z'' (No. 3), by pressing the PF key, the screen reading control section 3 reads out the screen indicated by the screen number (FIG. 3) in the corresponding file in the screen storage section 2, and displays it on the screen display section 5. .

Or after pressing the screen call key from keyboard 6,
By inputting a 4-digit screen number, for example 'A100'' and pressing the execution key, the screen reading control unit 3 reads the screen indicated by the screen number in the corresponding file in the screen storage unit 2, and displays the screen. It is displayed on the display section 5.

■After keying in data on the keyboard 6, by pressing the execution key, the input data is sent to the host 1~computer, processed within the host computer, and the corresponding screen number and data are sent to the terminal. come. In the screen common control section 4, the screen reading control section 3 calls the corresponding screen from the screen storage section 2, and displays it on the screen display section 5, superimposing it on the data.

e) Also, if the screen is changed on host 1~, the changed screen will be transferred when connecting with the host computer,
It is stored in the screen storage section 2 by the screen writing control section 1.

In addition, enter the screen ID as shown in Figure 3 with one character #, ″
Instead of dividing into 'B'' and ~1Z'', this can also be achieved by making the following correspondence. Sunawachi, 3rd
Figure teno screen ID ``A'', ``r3'', -'Z
Instead of ', shift the coat to 1 and display the hexadecimal X'
A1', X'A2', ~X'+3Δ'.

By taking this kind of response, screen fouls A-Z
can be made to correspond to In addition, by making such a response, compatibility with the conventional system can be maintained by using it in combination with the current Pl' key cover section.

In addition, although each control section is arranged in the terminal controller in Fig. 1, it can also be realized by connecting each control section and the screen storage section to the screen display section 5 and keyboard 6 without providing a terminal controller. It is.

〔Effect of the invention〕

As explained above, the present invention reduces the processing load on the host computer, reduces the line utilization rate of the network, and reduces the screen usage rate by storing and managing the screens of screen-type terminals up to 26 x 256 (=6656) screens as terminal local screens. This has the effect of improving display speed and reducing line usage charges when using a bucket 1 to switched network as a network. Furthermore, by not changing the conventional screen format, it is possible to maintain conventional compatibility on the host computer.
