Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a map information screen sequential automatic switching technique, and more particularly, in a communication network connecting a center and multiple points, switching of map information on the center side is based on an incoming call from each point. It is related to the technology performed.

[0002]

2. Description of the Related Art When using a personal computer (hereinafter abbreviated as a personal computer) and a screen to display map information of an area associated with each point on the center side, a personal computer terminal is associated with each point. If you prepare it, you can display all the points, but it is not economical.

When important information is sent, it becomes more difficult to find a desired screen as the number of points increases.

From an economical point of view, it is conceivable that the display on the screen is reduced so that all the areas are displayed. However, if the reduction ratio is high, the detail portion of the screen becomes difficult to see. The desired information becomes even harder to find.

Therefore, it is conceivable to leave the display of each area in the map information as it is and switch and display the map information of the area corresponding to each point.

Conventionally, when a plurality of screens are switched and displayed, the operator of the terminal inputs the identification number of the screen to be displayed into the personal computer, and the inside of the personal computer switches to the screen corresponding to the input identification number. In the display device, the screen is displayed.

[0007]

However, the above-mentioned conventional technique has a problem that the terminal operator must eventually perform the operation of sequentially switching, that is, the input of the identification number, and the human-machine interface is low. It was

Further, there is a problem that a map of a wide area cannot be displayed on the display screen of the center so that it can be seen at a glance.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a practical and effective display screen for a personal computer having a screen display processing capability lower than that of a workstation. It is to provide a technology capable of switching and displaying map information.

Another object of the present invention is to provide a technique capable of dramatically improving the apparent screen display capability of a personal computer.

The above and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

[0012]

In order to achieve the above object, the present invention, in a communication network system connecting a center and multiple points, switches the map information on the side of the center based on an incoming call from each point. It is a method of automatically switching the map information screen sequentially, and when there is an incoming call from a certain point to the center,
The communication network interface receives, extracts the area identification information of the transmission point from the received content, temporarily stores it in a buffer, and then receives the accumulated area identification information in the predetermined order and displays the image information of the map database corresponding to the identification information. The most main feature is to automatically and sequentially switch and display.

[0013]

According to the above-mentioned means, when an incoming call arrives at the center from a certain point, the communication network interface receives it, extracts area identification information of the originating point from the received contents, and temporarily stores it in a buffer. Since the image information of the map database corresponding to the identification information received in the predetermined order is automatically switched and displayed, the physically limited PC screen display capability is improved, making it more effective and practical. Screen display can be performed. This makes it possible to dramatically improve the apparent screen display capability of the personal computer. For example, a map of a wide area can be displayed at a glance on the display screen of the center. Also, the human-machine interface can be improved.

[Table 1]

Next, the function selection of the MAVDC of this embodiment will be described.

Each area map screen has a MAVDC screen switching time designating section and an area screen direct switching designating section as common input sections which can be designated manually by a mouse of a personal computer or the like. The area screen direct switching designation unit also serves as a status display (presence or absence of information) of an area other than the map being displayed on the screen.

FIG. 6 is a diagram for explaining the screen transition of the MAVDC of this embodiment.

In FIG. 6, a telephone call is made from the location a in the A branch area to the personal computer 4 of the center, and after confirming the response of the personal computer 4, information such as a residence number and a personal number is sent by a PB signal (button signal of a touch-tone telephone). By sending, the personal computer 4 analyzes the information and outputs it to the "when, where, who, what, etc." map information screen. Less than~
The movement of is also the same.

The operator of the personal computer 4 of the center is MAVD
By using the function of C, it becomes possible to manage the whereabouts and movements of people in real time and in a wide area centrally with one personal computer. As can be seen from this example, the map screen can be effectively used by implementing MAVDC.

Next, an embodiment of the kanji compression display method used in the present invention will be described.

The present invention enables more kanji characters to be displayed on a personal computer screen having a display limit, so that 1/2, 1/4
It realizes compressed kanji display. With the current PC, text (kanji) display is 25 characters per line on a single screen.
A line can display only 1000 characters at maximum.

FIG. 7 is a diagram showing the current state of the text screen display and the graphic screen display, FIG. 8 is a flow chart of the calculation process of the algorithm of the kanji compression display method of this embodiment, and FIG. 9 is the “north” in this embodiment. 10 is a diagram showing an example of horizontal compression of half-width Chinese characters in FIG. 10, FIG. 10 is a diagram showing calculation processing results of the algorithm in FIG. 9, and FIG. 11 is a half-width Chinese character of “North” in the present embodiment. FIG. 12 is a diagram showing an example of vertical compression of squares, and FIG. 12 is a quarter of the double-byte Chinese character of “North” in the present embodiment.
It is a figure which shows the example which (longitudinal-width half-width) compressed.

In the flowchart of FIG. 8, the full-width character string to be displayed is converted into Kanji code (step 201),
Graphic screen specified in advance (G-VRAM)
Specific location (X coordinate = 0 to Y coordinate = 1 in the example of FIG. 9)
Full-width Kanji characters are output to 6 × 22 + 2) and displayed (step 204). One double-byte kanji character displayed is composed of 16 dots in the vertical direction (0 ROW to 15 ROW) and 16 dots in the horizontal direction (0 bit to 15 bits) as shown in FIG.

The dots on the graphic screen (G-VRAM) are set in the horizontal direction from 0ROW to 1ROW by variables A1 and A2.
The contents of the dot are fetched by 8 bits each. In the 0ROWth processing, the variable A1 is set to the left 8-bit value "2" (step 208), and the variable A2 is set to the right 8-bit value "32" (step 209).

The logical sum of the value of the variable A1 and the value shifted to the right by one bit is calculated and placed in the variable AL (step 2).
10). When the value of the variable A1 is "2", "1" is set at the first bit like "0010", but this is logically ORed with "0010" by shifting it by one bit to the right, and "00" is obtained.
11 "is put into the variable AL. This process is a process for preventing the dots from falling out when the compression is performed in the horizontal direction (FIG. 9). The 8 bits of this variable AL are compressed to 4 bits. The variable ALH $ replaced with the hexadecimal number is "&H1"(& H1 indicates the hexadecimal number) (step 212) (FIG. 10). The same applies to the variable on the right side. ARH $ = & H4
Is obtained (steps 213 to 215).

A character string is added to the variable ALH $ and the variable ARH $, and the result is substituted into the variable AX $ (step 216). In this case, AX $ = & H 14 is included. This variable AX
The value of $ represents the dot array for 1 ROW of the half-width half-width compressed Chinese character and the quarter (horizontal-width half-width) compressed Chinese character (FIG. 9, FIG. 11, FIG. 12). If you want to display half-width, half-compressed Chinese characters, put this 1R in any place you want to display.
The dot array for OW is displayed (step 217).
These processes are repeated for 16 ROWs, and step 207
When the loop J is displayed while being shifted by one dot in the Y direction, it is possible to display a half-width half-compressed Chinese character for one character. By repeating this for the character string to be displayed, it is possible to display the character string of half-width, half-compressed Chinese characters (steps 202, 20).
5) (Fig. 9).

In the case of 1/4 (vertical / horizontal half-width) compressed Chinese characters, when displaying the variable AX $, 2 ROW's worth of data is 1 ROW.
It becomes possible by overwriting (step 21).
8).

Further, the 0ROW variable AX $ is set to 0ROW.
By writing the variable AX $ of the 1ROW to 0ROW, the dot array of the logical sum of the dot array of the 0ROW and the array of the 1ROW can be displayed (FIG. 12).

This method can also be applied to the display of half-width, half-compressed Chinese characters (FIG. 11).

As can be seen from the above description, according to this embodiment, the following operational effects can be obtained.

.. By using the RAM-DISK, it is possible to switch and display a large area on the actual display screen (the number of areas depends on the capacity of the RAM-DISK).

.. Since a call from outside the displayed screen area can be automatically switched to a trigger, no human operation is required.

.. Automatic screen switching is possible even when there is no call trigger (switching time can be changed), so the entire screen can be displayed.

.. By combining the 1/2 and 1/4 Chinese character compression display methods, it is possible to prevent irrationalities such as unreadable characters, unlike the scaling method.

From the above, the following effects can be obtained. (1). By improving the physically limited PC screen display capability, more effective and practical screen display is possible.

(2). The added value of the personal computer can be dramatically increased, and the personal computer can be used practically and effectively.

(3). A system with improved human-machine interface can be developed.

(4). It is highly practical and versatile and can be applied to various systems.

Although the present invention has been specifically described based on the embodiments, the present invention is not limited to the above embodiments, and it goes without saying that various modifications can be made without departing from the scope of the invention. .
