Abstract

PURPOSE:To quickly display even a complicated picture and to improve the maintainability by not only reading out a command group stored in a command group storage part but also displaying a picture corresponding to the command group on a display device at the time of inputting a display command to a picture display control part. CONSTITUTION:Command groups are generated from a fixed picture source 6 and are stored in a command group storage device 4 at the time of offline, and a required command group is read out from the command group storage device 4 to generate a fixed picture on a CRT display device 7 at the time of online. Consequently, the processing to edit a command group from an execution subroutine group at the time of online is omitted, and contents of the fixed picture can be easily changed because the fixed picture source 6 is described in a descriptive language. Thus, even a complicated picture like a map picture is quickly displayed, and the maintainability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a screen creation device used when displaying a fixed screen or the like at high speed.

(Prior Art) As a high-speed screen display method for terminal devices and the like, a normalization method within the - shell is used.

This technique maximizes the communication speed of the terminal control processor and eliminates unnecessary commands (
By deleting as many redundant commands as possible, the screen can be displayed on a CRT at high speed.

(Problems to be Solved by the Invention) In this normalization method, a method is adopted in which the communication speed is increased to display the screen at high speed.

However, such a method is not a fundamental solution for shortening data processing time due to hardware limitations.

Furthermore, in the normalization method, it is necessary to carefully select commands and delete redundant commands, which poses problems in that it takes too much time and effort in the initial design and manufacturing process and is also difficult to maintain.

In order to eliminate this inconvenience, a method of creating screens using descriptive language was developed.

In this method, a fixed screen is described using a descriptive language, and then batch processing is performed to generate a group of execution subroutines for displaying the fixed screen. Then, when a display command is input, the command corresponding to this execution subroutine is edited and the CRT is
A screen is created by displaying a fixed screen corresponding to the command above and incorporating display information input online onto the fixed screen.

However, in the method of creating a screen using such a descriptive language, the operation of reading an execution subroutine and the operation of creating a command from this execution subroutine are repeated every time a display command is input, so it is difficult to create a fixed screen. There was a problem that the operation became slow.

In particular, when the fixed screen display format is complex, such as a map display, the number of execution subroutines that are generated during batch processing is large, so it takes time to edit commands from each of these execution subroutines. There was a problem that the display speed became too slow.

In view of the above circumstances, it is an object of the present invention to provide a screen creation device that can display even complex images such as map screens at high speed and that can improve maintainability.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, a screen creation device according to the present invention includes an execution subroutine creation section that creates necessary execution subroutines based on fixed screen information written in a descriptive language. , a command group creation section that creates a command group based on the execution subroutine group created by this execution subroutine creation section, a command group storage section that stores the command group created by this command group creation section, and a display command. The present invention is characterized by comprising a screen display control section that reads out a command group stored in the command group storage section when input, and displays a screen corresponding to the command group on a display device.

(Operation) In the above configuration, before the display operation, the command group creation section creates a command group from the execution subroutine group created by the execution subroutine creation section and stores it in the command group storage section. Then, when a display command is manually input, the screen display control section reads out the command group stored in the command group storage section and displays a screen corresponding to the command group on the display device.

(Embodiment) FIG. 1 is a block diagram showing an embodiment of a screen creation device according to the present invention.

The screen creation device shown in this figure includes an execution subroutine group creation device 1 that takes in a fixed screen source 6 and creates an execution subroutine group, and an execution subroutine storage that stores the execution subroutine groups created by this execution subroutine group creation device 1. device 2, a command group creation device 3 that reads the execution subroutine group stored in the execution subroutine storage device 2 and creates a command group, and a command group that stores the command group created by the command group creation device 3. It includes a storage device 4 and a command group execution device 5 that executes the command group stored in the command group storage device 4.

When offline, when a conversion command is input, the fixed screen source 6 written in descriptive language
is compiled to create a command group, which is stored in the command group storage section 4. Thereafter, when a display command (man-machine command) is input while online, the command group stored in the command group storage section 4 is read out and a fixed screen is displayed on the CRT display device 7.

The execution subroutine group creation device 1 includes a batch processing unit 10 that takes in a fixed screen source 6 written in a descriptive language and creates an execution subroutine group corresponding to this fixed screen source 6. When the screen source 6 is input, the execution subroutine corresponding to this fixed screen source 6 is edited to create an execution subroutine group, which is stored in the execution subroutine storage device 2.

The execution subroutine storage device 2 is constituted by an external storage device, etc., and stores the execution subroutine group when it is supplied from the execution subroutine group creation device 1, and stores the stored execution subroutine group when a read command is supplied. The subroutine group is read out and supplied to the command group creation device 3.

When a conversion command is input while offline, the command group creation device 3 reads out the execution subroutine group stored in the execution subroutine storage device 2 and edits the commands corresponding to the execution subroutine group to create a command group. a terminal control processor output unit 12 that takes in and outputs the command group created by the subroutine operation unit 1];
A terminal control processor human power section 13 that takes in a group of commands output from this terminal control processor output section 12, and an input-only driver that takes in a group of commands that are output from this terminal control processor input section 13 and supplies them to the command group storage device 4. It is equipped with 14.

When a conversion command is input offline, the execution subroutine storage device 2 as shown in FIG.
The execution subroutine group stored in the execution subroutine group is read out, a command group corresponding to this execution subroutine group is generated, and this is stored in the command group storage device 4.

The command group storage device 4 is constituted by an external storage device, etc., and stores a command group when it is supplied from the command group creation device 3, and stores the stored command group when a read command is supplied. is read out and supplied to the command group execution device 5.

The command group execution device 5 is an output-only device that reads out the command group specified by the conversion command from among the command groups stored in the command group storage device 4 when a man-machine command (display command) is supplied during online operation. It includes a driver 15 and a terminal control processor output unit 16 that sequentially executes each command of the command group read by the output-only driver 15 to display a fixed screen on the CRT display device 7.

When a man-machine command is input during online mode, the output-only driver ]-5 selects a command from among a plurality of command groups stored in the command group storage device 4 by the man-machine command as shown in FIG. At the same time, each command constituting the command group is sequentially executed by the terminal control processor output section 16, and a fixed screen is displayed on the CRT display device 7.

In this embodiment, a command group is created from the fixed screen source 6 when offline and stored in the command group storage device 4, and a necessary command group is generated from the command group storage device 4 when online. Since the fixed screen is read out and created on the CRT display device 7, the process of editing the command group from the execution subroutine group when online can be omitted. This allows even complex items such as map screens to be displayed at high speed.

Furthermore, in the above-described embodiment, since the fixed screen source 6 is described using a description language, the contents of the fixed screen can be easily changed, thereby improving maintainability.

Furthermore, in the embodiment described above, the fixed screen source 6 is created using a descriptive language, but a fixed screen is created on a CRT screen using a mouse, keyboard, etc., and this fixed screen is created using a descriptive language. Alternatively, the fixed screen source 6 may be created by converting it into . In this way, the fixed screen creation work can be further mechanized.

Furthermore, in the above-described embodiment, the terminal control processor output section 12.16 and the terminal control processor input section ]3 are described as being independent, but these are connected to the output and output terminals of one terminal control processor. , may be configured by input terminals.
