CONSTITUTION:The name of the movement route is specified by a movement data call device 10 and respective coordinates indicating the movement route 4 in a movement data storage device are read in a movement data holding device 11. Then when the movement indication data on the moving direction, moving speed, etc., are inputted on a screen movement indication device 12 composed of a keyboard, etc., the respective coordinates are inputted to a data editing and transfer device 6 according to the movement indication data. Consequently, an image which is moved (scrolled) in the specified direction and at the specified speed along a railroad is displayed on a display unit 5. Consequently, an operator only inputs the moving direction and moving speed to move the screen data 7 displayed on the display unit 5 automatically along the movement route 4.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a display device that moves screen data displayed on a display in an electronic computer, and particularly relates to a display device that moves screen data displayed on a display in an electronic computer, and in particular, The present invention relates to a display device that moves screen data.

(Prior art) For example, when displaying a large map or large drawing on a display device that can only display a unit amount of screen data, you can reduce the size of the map or drawing you want to display, but if you reduce the size, details cannot be identified on the display screen. It disappears. To do this, the image to be displayed is divided into several fragments, each fragment is given a screen number and screen name and stored as a database, and the database is searched using these screen numbers and screen names. The desired screen data was displayed on the display.

However, in this method of dividing one large screen data into multiple parts and storing them, when displaying an essentially seamless image such as a map, when viewing data near the border of the map, had a drawback that made it extremely difficult to use.

In order to solve this inconvenience, for example, a map etc.
For example, by reading each image with an image scanner,
The screen data read from each image is combined into one seamless large screen data using a computer, and this large screen data is stored as a database in a storage device. A display device has been developed that extracts a portion of the image and displays it on a display. Then, the screen data of the unit amount displayed on this display is continuously moved (
scroll) to display. Therefore, large screen data that cannot be displayed on one screen can be viewed smoothly and continuously by scrolling.

Note that this type of seamless screen movement is called an infinite scroll function.

If you want to search for the screen data you want to observe from among such large screen data, or if you want to follow the screen along a specific piece of equipment, you can usually use a mouse or joystick to read the screen data displayed on the display. Move it around to find the desired screen data.

However, the operation of moving (scrolling) the display screen using the mouse or joystick described above is extremely troublesome. Further, for example, if the user wants to view the screen from a certain direction with respect to a specific object such as a road or railway on a map, it is necessary to instruct the user to rotate the screen, which makes the operation extremely complicated.

In addition to the above-mentioned roads and railways, examples of such specific objects include power transmission lines, gas pipes, water pipes, sewage pipes, and the like. In such maps and drawings, it is cumbersome and inefficient to move the screen along the target equipment or route each time, resulting in a significant decrease in work efficiency.

(Problem to be Solved by the Invention) As described above, in conventional display devices, in order to move (scroll) the screen displayed on the display, it is necessary to manually move (scroll) the screen displayed on the display while observing the display screen using a mouse or joystick. Since this has to be done manually, it is very complicated for the operator and reduces work efficiency.

The present invention was made in view of these circumstances,
By pre-memorizing the movement route on the large screen data, the display screen of the display unit can be automatically moved along this movement route, greatly reducing the burden on the operator and improving work efficiency. The purpose is to provide a display device.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above problems, the present invention provides a display device that displays a unit amount of screen data, and a large screen that exceeds the screen data that can be displayed at one time on this display device. A large screen data storage device that stores data; a data storage device that stores and holds a unit amount of screen data to be displayed on a display out of the large screen data stored in the large screen data storage device; a movement data storage device that stores a predetermined movement route; a screen movement instruction device that instructs movement of screen data to be displayed on a display device along the movement route stored in the movement data storage device; data editing that sequentially updates the screen data displayed on the display by sequentially sending unit amounts of screen data centered on each coordinate on the movement route sequentially output from the screen movement instruction device to the data holding device;・It is equipped with a transfer device.

Moreover, in another invention, in each of the above-mentioned means,
The moving route of the object on the large screen data is stored in the moving data storage device, and the current state of the object is determined from the moving speed information of the object moving along the moving route stored in the moving data storage device. A current position calculation device for calculating position information is provided, and the data editing/transfer device converts a unit amount of screen data centered on each coordinate on the movement route sequentially output from the current position calculation device in large screen data into data. The screen data displayed on the display device is sequentially updated by sequentially sending the data to the holding device.

(Function) According to the display device configured in this way, the route (direction) in which the unit amount of screen data displayed on the display device is to be moved is determined.
is stored in the movement data storage device in the form of a movement route on the large screen data.

Then, when the screen movement instruction device is started, each coordinate of the movement route is output, and the data editing/transfer device converts the screen data of the unit amount centered on the coordinates out of the large screen data in the large screen data storage device into data. It is delivered to the display via a holding device. Therefore, the screen data displayed on the display automatically moves along the movement route.

In another aspect of the invention, a movement route along which an object such as a car moves on the large screen data is stored in the movement data storage device. Then, when the object moves along the movement route, the current position information of the object is obtained from the movement speed information, and the coordinates on the movement route are obtained from this current position information, so the display is displayed as described above. The displayed screen data moves. In this case, the screen data moves (scrolls) so that the current position of the object is located at the center of the display screen.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of a display device according to an embodiment. In the figure, 1 is a large-screen data storage device composed of, for example, a CD-ROM and an optical disk reader;
In the large screen data storage device 1, for example, a railway map shown in FIG. 2 is stored as large screen data 2.

Further, in the movement data storage device 3, a movement route 4 along a railway, for example, which is to be searched sequentially on the large screen data 2 shown in FIG. 2 is stored. Specifically, as shown in FIG. 3, each coordinate (X) from the movement start position to the movement end position on the movement route 4.

Y+ ), (X2.Y2), (X3.Y3)...
- (XN, YN) is stored. Note that the sampling interval of each coordinate is set in consideration of ease of viewing for the operator, smoothness of screen movement, etc.

Further, the display device 5 is composed of, for example, a CRT display device, and is a display capable of displaying only the unit amount of screen data 7 shown in FIG. 2 out of each data of the large screen data 2 at a time. It has a screen. Then, a specified unit amount of screen data 7 in the large screen data 2 of the large screen data storage device 1 is read out by the data editing/transfer device 6 and transferred to the data holding device 8. The screen data 7 stored in the data holding device 8 is sent to the display 5 via the display control device 9 and displayed.

The mobile data retrieval device 10 also includes the mobile data holding device 1.
1 stored in the mobile data storage device 3.
The route name of the moving route 4 shown in the figure is specified and a read command for each coordinate shown in FIG. 3 is sent out, so that each coordinate indicating the moving route 4 is temporarily stored. In addition, the screen movement instruction device 12
is formed by, for example, a keyboard operated by the operator, and when the operator inputs a key to input the moving direction and moving speed of the screen along the moving route 4, the screen moving direction, moving speed, etc. are transmitted to the screen movement control device 13. Sends movement instruction data. This screen movement control device 13 includes a screen movement instruction device 12.
Based on the movement direction and movement speed of the movement instruction data input from , each coordinate (X+, Y+), (X2
, Y2).

(X3.Y3)... (XN, YN) are read out sequentially and sent to the data editing/transfer device 6 via the automatic side terminal of the manual/automatic switching device 14. Therefore, the data editing/transfer device 6 has the large screen data 2 shown in FIG.
The respective coordinates of the above movement route 4 are input at time intervals and in an order according to the movement speed and movement direction specified by the screen movement instruction device 12.

The data editing/transfer device 6 is a large screen data storage bag! fl
Of the large screen data 2 stored in the large screen data 2 , a unit amount of screen data 7 centered on the sequentially input coordinates is sequentially read out and sent to the data holding device 8 . Therefore, the screen data 7 is displayed on the display 5. Furthermore, each time new coordinates are input to the data editing/transfer device 6, the screen data 7 written in the data holding device 8 is rewritten into screen data centered on the new coordinates. Therefore, the unit quantity screen data displayed on the display 5 is also updated sequentially. Therefore, to the operator, the screen data on the display 5 appears to move (scroll) along the movement route 4 at the speed and direction specified by the screen movement instruction device 12.

A screen movement manual instruction device 15 is connected to the manual side terminal of the manual/automatic switching device 14. This screen movement manual instruction device 15 is composed of, for example, a mouse or a joystick, and operates the mouse or joystick to change the movement route 4 within the screen data 7 of the unit amount displayed on the display 5. Input each coordinate on screen data 2.

That is, when the automatic/manual switching device 14 is switched to the manual side, the display screen of the display device 5 can be moved (scrolled) by manual operation as in the conventional device.

Further, the coordinate data output from the screen movement manual instruction device M15 is inputted to the movement data editing device 16 as necessary. The movement data editing device W16 edits the input coordinates into a movement route 4 based on an editing instruction from the editing instruction device 17, and writes the edited coordinates into the movement data storage device 3.

Next, a procedure for moving the display screen of the display device 5 along the railway on the map shown in FIG. 2 using the display device configured as described above will be explained. In this case, it is assumed that large-screen data 2 of a map as shown in FIG. 2 is stored in advance in the CD-ROM of the large-screen data storage device 1.

First, according to instructions from the screen movement manual instruction device 15, automatic/
When the manual switching device 14 is turned to the manual side and the power of the entire device is turned on, screen data 7 of a unit amount centered on the coordinates inputted to the data editing/transfer device 6 is displayed on the display 5. There is. Then, the operator uses an image movement manual instruction device 15 such as a mouse to move the center position of the display to the starting point of the movement route on the large screen data 2. Then, as the mouse is moved along the railway on the displayed screen data, each coordinate (X+, Yl), (X2, Y2) on the movement route 4 is obtained.

(X,, Y,)... (XN, YN) are read and written to the mobile data storage device 3 via the mobile data editing device 16 as shown in FIG. Furthermore, the movement route 4 is started using the editing instruction device 17.

Perform editing operations such as termination, suspension, deletion, addition, etc. Furthermore, the travel route name is also set in the travel data storage device 3 at the same time.

When the above preparation process is completed, the automatic/manual switching device 14
into the automatic side. And mobile data calling device 10
Specify the movement route name in the movement data storage device 3.
The above-mentioned coordinates indicating the movement route 4 are read into the movement data holding device 11. Note that it is also possible to read from an intermediate position on the movement route 4. When movement instruction data such as movement direction and movement speed is inputted using a screen movement instruction device 12 comprised of a keyboard or the like, each coordinate is inputted to the data editing/transfer device 6 in accordance with this movement instruction data. As a result, as shown in FIG. 4(a), the display 5 displays an image that moves (scrolls) along the railway serving as the travel route 4 according to the specified direction and speed.

In this way, the moving route 4 is transferred to the moving data storage device 3.
If this setting is made, the screen data 7 displayed on the display 5 will automatically move (scroll) along the moving route 4 by simply inputting the moving direction and moving speed by the operator. Therefore, the operator can observe the image displayed on the display 5 without being bothered by scrolling operations. Therefore, operability can be greatly improved.

Additionally, the data editing/transfer device 6 may be connected to a fourth
As shown in FIG.
It is possible to read out a unit amount of screen data 7 from the large screen data storage device 1 by calculating the slope of . That is,
For example, when using a map information system to investigate the installation environment of power transmission lines, or to survey and manage buildings and topography in a certain area on both sides of a railway, images of areas other than the vicinity of power transmission lines and railways are not required. . It is preferable that the power transmission line is displayed in the center of the display 5, and that the power transmission line is always displayed in the horizontal direction. Therefore, even when moving (scrolling) the screen, there is always a power line.

If you move the power line along the railway so that the railway is displayed horizontally, the screen movement operation will become extremely efficient.

In addition, by applying it to a monitoring system that maintains and manages various equipment installed in the gas piping network and monitors abnormalities such as pressure and temperature, a diagram of the pipe network including the target equipment will be automatically displayed in the event of an abnormality. At the same time, it becomes easy to move the display screen upstream or downstream. In addition, this method can be applied not only to gas piping networks, but also to water, steam, fuel, etc. piping and electric wire management in factories, and when tracing complex piping, the screen can be moved according to a preset movement route. (
scrolling).

A current position calculation device 18 is provided in place of the editing instruction device 17 and movement data editing device 16 shown in FIG. A speed signal of a car as an object is inputted to the current position calculation device 18 from the outside. Moreover, in the large screen data storage device 1, large screen data 2 of a road map is stored instead of a railway map.

Further, in the movement data storage device 3, each coordinate of a movement route 4 along a road is stored together with a movement route name indicating a road name. It is assumed that the vehicle as the object travels along the travel route 4 having the travel route name specified by the travel data retrieval device 10.

In such a display device, the start position on the travel route 4 is displayed at the center position of the display 5 before the car starts traveling, and the coordinates on the travel route 4 output from the current position calculation device 18 are used as travel data. The coordinates are made to match the coordinates output from the holding device 11.

When the above preparation work is completed, the vehicle is driven along the travel route 4. The current position calculation device 18 calculates the amount of movement along the movement route 4 using the speed signal output from the car. The screen movement control device 13 determines the current position of the car on the movement route 4 from the amount of movement, and sends the data to the data editing/transfer device 6.
Send to.

The data editing/transfer device 6 then reads out a unit amount of screen data centered on the input coordinates from the large screen data storage device 1 and sends it to the data holding device 8. As a result, the current position of the vehicle on the travel route 4 is always displayed centered on the display 5.

That is, the display screen of the display device 5 is automatically moved (scrolled) as the car moves.

[Effects of the Invention] As explained above, according to the display device of the present invention, the movement route on the large screen data is stored in advance. Then, the display screen of the display device is automatically moved along this movement route. Therefore, unlike conventional devices, there is no need to input movement position information each time using a mouse, joystick, or the like. Therefore, the burden on the operator can be significantly reduced, and the efficiency of searching display screen data can be improved.

Furthermore, when installed in a car or the like, the screen data is moved so that the current position is always displayed on the display, making it possible to provide a good navigator system.
