(1) NEC Publication MS Windows 3.0 Programmer's Guide (2) Windows Programming Fuji Software Education Publishing Department November, 1988 Now, the movement status of a moving body is a position symbol indicating the position of the moving body and movement. The data block showing the attributes of the body, the position symbol, and the reeler connecting the data blocks are visually displayed on the display screen. Further, in order to easily grasp the position of the moving body, the geographical data of the moving space are visually displayed as background data at the same time. When a large number of moving objects are arranged on the display screen, the concealment occurs due to the overlap of the display data caused by the movement of the moving objects. Conventionally, the processing for avoiding this has mainly depended on the method of coping with by examining the display area of the individual movement status.

The conventional method will be described with reference to the flowchart of FIG.
When the display data of the position symbol and data block of a mobile object moves or changes its shape, the range of influence such as hiding the visible display of the position symbol of another mobile object and the display data of the data block due to the change and shape change. Is calculated (process procedure 40 in FIG. 4), the display data in the range is erased (process procedure 41), and the erased display data in the range is redrawn as background data (process procedure 42). Next, the position symbol of the moving body, the movement of the data block, and the shape change are drawn (processing procedure 43). Then, it is checked whether or not there are other position symbols and data blocks of the moving body that are affected (procedure 44). When there is another moving body that is affected, the position symbol and the data block are redrawn as the background data (processing procedure 45). The display data is visually displayed on the display screen by such a processing procedure.

[0005]

In the above-mentioned conventional method, it is determined whether or not there is a position symbol and a data block of the moving body which are affected each time the position symbol and the data block of the moving body move or change in shape. A large number of mobile location symbols and data blocks must be examined. Moreover, calculation of the affected range and calculation of the affected range on the background screen within that range are time-consuming and complicated processes, making it difficult to develop the application program.

An object of the present invention is to set a plurality of visible display areas (referred to as parent windows) on a display screen, and further to provide a plurality of visible display areas (referred to as child windows) within each visible display area. And a window system that can independently display display data in each of the child windows. That is, the display data is drawn by associating the spatial geographic data of the background and the position symbols and data blocks of each moving body in the parent window individually in the child window. Then, the problem of concealment due to overlapping of display data is solved by the control function of the window system, and the movement status data of the moving body can be easily visually displayed on the display screen.

[0007]

According to a visible display control method for a moving body of the present invention, in the visible display control method for a moving body, the moving status data of the moving body is displayed on a display screen. A movement status data analyzing unit that distributes to each processing of visible display of the moving body, change of the visible display shape, update of the visible display position, and display data of the spatial geographic data in the parent window and each of the display data of the movement status data. Window generation control means for drawing each in each child window and for generating the parent and child windows, and the display data hidden by the weight of the parent and child windows caused by the movement of the moving body. Display data control means for drawing in the parent and child windows as background data, and a display table for displaying the display data on the display screen. Wherein it is composed of a display data output means for outputting a window to.

Embodiments of the present invention will now be described with reference to the drawings.

Referring to FIG. 1 showing the configuration of one embodiment,
Display data consisting of a position symbol indicating the position of the moving body, a data block indicating the attribute, and a reeler that connects the position symbol and the data block is visually analyzed to analyze the movement status data to newly display the moving body. Display, position symbol and movement status data analysis unit 1 that transfers movement status data to each process that changes the position of the visible display of the data block, and display data of background geographical data in the parent window and for each moving object. The display data is concealed by allocating the display data as display data to be visually displayed in the child windows, respectively, and the window generation control unit 2 for generating the parent and child windows, and by moving the child windows, the parent and child windows overlap each other. Display data control unit 3 that eliminates the problem and display data on the display screen Constituted by a display data output unit 4 for viewing the display.

Next, referring to FIGS. 2 and 3 for explaining the operation of this embodiment together with FIG. 1, the movement status data analysis unit 1 receives the movement status data of the moving body, and according to the analysis result. The window generation unit 2 and the display data control unit 3 are activated (process procedure 21 in FIG. 2). If the movement status data is a notification of the occurrence of a new mobile unit, the window generation control unit 2 is activated and the position symbol 1 of the new mobile unit is activated.
3 (shown in FIG. 3) and a child window 12 for allocating the display data of the data block 14 (procedure 23). The display data control unit 3 has its child window 1
In order to visually display 2 on the parent window 11, the display position is calculated from the position data of the movement status data (processing procedure 24). Then, the display data of another window hidden by visually displaying the child window 12 of the new moving body is drawn as display data on the background screen 16 of the child window 12 (processing procedure 25). Further, the position symbol 13 and the data block 14 of the moving body are drawn on the child window 12 as display data (processing procedure 26). Then, the display data output unit 4 visually displays the child window 12 having the display data including the position symbol 13, the data block 14, and the captured background data of the moving body (processing procedure 27).

Next, when the movement status data is a movement notice of the position of the moving body, the window generation control unit 2 determines the new display position of the child window 12 having the position symbol 13 of the moving body and the data block 14. Calculate (processing procedure 35). Then, the display data control unit 3 takes in other display data hidden by the movement of the child window 12 as display data of the background of the child window 12 (processing procedure 36). Further, the position symbol 13 of the moving body and the data block 14 are drawn as display data on the child window 12 (procedure 37). Next, the display data output unit 4
Visually displays the child window 12 having the position symbol 13, data block 14, and background data of the moving body (procedure 38). When you move the child window 12,
In the other affected area of the child window 12 and the affected area of the parent window, the display data is hidden, so that it is necessary to redraw. The window system automatically notifies the display data control unit 3 of the information about the affected area, and the display data control unit 3 redraws the display data hidden according to the information (processing procedure 39).

When the movement status data is a notice of deletion of the visible display of the moving body (processing procedure 22), the window control unit 2 deletes the corresponding child window 12 (processing procedure 33). Then, similarly to the case where the child window 12 is moved, the window system notifies the information about the display data that needs to be redrawn, and the display data control unit 3 redraws the display data of the corresponding area according to the information (process). Step 34). When the operator makes a shape change request for the position symbol 13 of the moving body and the data block 14 (procedure 22), the window generation control unit 2
Generates the child window 12 having the position symbol 13 and the data block 14 of the corresponding moving object (procedure 28). Then, the display position of the child window 12 is calculated (processing procedure 29). Furthermore, the position symbol 13 of the moving body, the data block 14, and other display data hidden by the shape change are taken into the background data of the child window 12 (procedure 30). Further, the position symbol 13 of the moving body and the data block 14 are drawn as display data on the corresponding child window 12 (processing procedure 31). Then, the display data output unit 4 outputs the child window 12 having the position symbol 13 and the data block 14 of the corresponding moving object for visible display on the display screen (procedure 32).

[0013]

As described above, according to the present invention, when the position symbols and data blocks of a large number of independently moving mobile objects are visually displayed on the display screen, the position symbols and data of each mobile object are displayed. The block is drawn in each individual child window 12, and at that time, other hidden display data is taken into the background data and displayed visually in the child window 12. Therefore, the window system notifies the application program of the area affected by the movement request, the deletion request, and any other display shape change request for the position symbol and data block of the moving body, so that the display position of another moving body can be searched. An application program that requires complicated processing such as calculating the position symbol of the affected mobile object and the display position of the data block and obtaining the area of the display data affected by the concealment becomes unnecessary. As a result, the visual display on the display screen of the moving body can be easily realized.
