Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rainfall information display method and a rainfall information display terminal device, and particularly to a weather forecast, a weather information system, a river information system, a rainfall radar information system in a sewer system, a radar rain gauge, Information collected by surface rain gauges scattered at each point is collected,
The present invention relates to a rainfall information display method for displaying together with map information, a rainfall information display system for a rainfall information display terminal device, and a sewer system.

[0002]

2. Description of the Related Art On the terminal side of a meteorological system such as a rainfall radar or the Meteorological Agency's AMeDAS, the collected rainfall information is displayed on a CRT together with map information. For this display, a method is used in which rainfall information is superimposed on map information and displayed in a mesh color, and the amount of rainfall is expressed by changing the color according to the size of rainfall information. There is. However, in this method, when the rainfall information is displayed, the map information may be filled and may not be visible. In particular, when the range of the rainfall area is wide, it becomes difficult to associate where and how much rainfall there is with the map information. As a countermeasure against the above, when displaying these on a graphic display device such as a CRT, as shown in FIG. 7, a gap is provided between meshes so as not to completely cover the rainfall area. By doing so, map information can be seen in the gaps, and it becomes possible to correspond to the topographic map. Alternatively, there is also a method of making the map information visible by redrawing the map information after displaying the rainfall information in color.

[0003]

With the above method of filling with a gap between meshes, the topographic map is still difficult to read. In addition, in the method of redrawing the map information after displaying the rainfall information, it has to be redrawn every time the rainfall information is refreshed, which not only takes time to display, but also the map information which should originally be a fixed part. Redrawing is visually unpleasant. Further, in order to record the rain amount information displayed in a mesh color, when a hard copy of a graphic display device such as a displayed CRT screen is taken, the number of colors that can be expressed by a color hard copy is usually limited. Therefore, not all the colors used for displaying the rainfall information can be output in color hard copy, and there is a problem that correct information cannot be recorded. Furthermore, in the conventional method,
If you want to display only the heavy rainfall area, for example, "heavy rain area of 30 mm or more" from the screen displaying the rainfall of all rainfall observation points, the mesh display of the area displaying the rainfall of "less than 30 mm" There is also a problem that erasing and redrawing of topographic map information are required, and it takes time to switch the display.

The object of the present invention is to make the topographic map easy to see even when the amount of rainfall is displayed, to prevent the ability of expressing information when a hard copy is taken from decreasing, and to display only the heavy rain area. (EN) It is possible to provide a rainfall information display method, a rainfall information display terminal device, a rainfall information notification system, and a sewer system that can easily display a rain area in a specific data range.

[0005]

[Means for Solving the Problems] The above object is to display the rainfall information in a shaded or shaded group so that the topographic map of the area where the rainfall information is displayed can be read, and according to the rainfall information, the shaded or shaded areas are displayed. It is achieved by changing and displaying the group form, and a display data generating means for generating the display data for each rainfall information distinguished by the form of the shaded or shaded group is provided and generated by the means. This is achieved by selecting and displaying only designated ones of the displayed data.

[0006]

[Function] Since a display pattern such as a shaded or shaded group is designated and displayed according to the amount of rainfall or the intensity of rainfall, the visibility of map information is improved unlike the filling by color display.
Also, even when the number of colors that can be displayed by the printing means is small,
Since the rainfall amount and rainfall intensity are represented by the display pattern, it is possible to easily make a hard copy. Furthermore, because separate display data is created for each amount of rainfall or rainfall intensity, it is possible to easily specify a specific rainfall intensity by having a function to specify whether to display or hide each of these data from the man-machine interface. Alternatively, it is possible to switch between displaying only the area where rainfall is observed and displaying all areas.

FIG. 1 shows a rainfall information terminal 215 or 215.
3 is a block diagram showing the internal processing of A. FIG. The rainfall data receiving unit 11 receives rainfall amount information such as rainfall intensity and rainfall amount through the communication interface 34, and stores it in the rainfall amount data temporary storage file 12 in the main storage device 32.
There are two types of rainfall information sent, such as history information, which is sent from the rainfall terminal side upon request, and instantaneous value information, which is sent at fixed intervals. Shall have a storage area. In the case of the latter information, the rainfall data temporary storage file is updated periodically. On the other hand, the operation input unit 17 is the keyboard 3
6, accepts a request from an operator entered through a man-machine interface such as a mouse 37. Requests from the operator include designation of screen display contents. Of the received inputs, those relating to the map information to be displayed (drawing number, display contents, etc.) are passed to the graphic search unit 19 and the corresponding map information is searched from the graphic file 15. In addition, attributes (for example, sewer pipe diameter,
Information related to equipment such as length and installation time) is passed to the display attribute search unit 18, and the corresponding attribute information is searched from the attribute file 16. Information about the display location such as the drawing number of the topographic map to be displayed is passed from the graphic search unit 19 to the rainfall information display editing unit 13. The rain amount information display / editing unit 13 develops the rain amount information in the rain amount data temporary storage file 12 into display hierarchical data in accordance with the information passed from the graphic retrieval unit 19. At this time, the display pattern, the display color, and the display hierarchy are selected from the correspondence table of the magnitude of the rainfall information such as the rainfall intensity and the rainfall, which is stored in the rainfall information display pattern storage unit 14, and the display pattern, the display color, and the display hierarchy. It is decided and edited into the display hierarchy data 102. Similarly, the map information is displayed by the graphic editing unit 100, and the attribute data is displayed by the display attribute editing unit 101.
Expand to 02. On the other hand, when determining the display layer, the request relating to the display layer selection among the requests input from the man-machine interface through the operation input unit 17 is passed to the display layer selection unit 103. The display hierarchy determining unit 103 selects data of a required hierarchy from the display information expanded in the display hierarchy data 102 according to the passed information. For example, the request to “display a rainfall area with a rainfall intensity of 30 mm or more” is passed in this procedure as a display hierarchy selection instruction, and the display hierarchy determination unit 103 selects the hierarchy that stores the rainfall intensity of less than 30 mm. It can be realized by removing from the display hierarchy of. Display hierarchy determination unit 103
The display hierarchy data selected in step S1 is displayed by the display calculation unit 104.
Is passed to the drawing display device 35, and each layer is superposed and output to the graphic display device 35. The display screen 105 is an example of a rainfall amount information display screen displayed on the graphic display device 35.

FIG. 4 is a flow chart showing a schematic process of the rain amount information display editing unit 13, and FIG. 5 corresponds to the rainfall intensity of the rain amount information display pattern storage unit 14. Figure 4
In process 41, the display area is calculated according to the drawing number or the like of the topographic map to be displayed, which is passed from the figure retrieval unit 19, and in process 42 the rainfall data corresponding to this is taken out from the rainfall data temporary storage file 12. . Normally, the rainfall information from the rainfall radar has one observation data for each square area of 250 m, 500 m, etc., and covers the entire observation area, so only the data included in the range displayed this time is selected. Will be done. Next, according to the process 43 for all the selected rainfall data, the processes 44, 4
5 Execute. In process 44, the display coordinates are determined and process 4
At 5, the display pattern, the display color, and the display layer are determined according to the value of the rainfall information such as the rainfall intensity with reference to the correspondence table shown in FIG. Here, as the display pattern, a pattern is selected that does not make the map information difficult to see when it is superimposed on the map information such as shading and diagonal lines. Therefore, when the rainfall information is displayed in an overlapping manner, the map information can be easily read and redrawing of the map information is not necessary. Figure 8
Is an example of the display, and indicates that both the map information and the rainfall amount information can be easily read. Further, even if the display colors such as shaded lines and diagonal lines are the same, the rainfall information can be sufficiently expressed, and thus it becomes easy to make a hard copy.

FIG. 6 schematically shows the structure of display hierarchical data. A layer for storing topographic maps and attribute information and a layer for storing rainfall information (rainfall intensity in this example) are set as different layers, and the layer for rainfall information is set to the magnitude of rainfall intensity defined in FIG. It is separated as a separate hierarchy accordingly. Therefore, when a request to display only a specific rainfall intensity range is received from the operation input unit 17, the display layer determination unit 103 can respond by not selecting a layer that displays the rainfall intensity range outside the range, and once displayed. It is not necessary to remove unnecessary parts from the screen, and the display time can be greatly reduced.

The present embodiment can be widely used for a weather forecast, a weather information system, a river information system, a rainfall radar information system for sewers, etc., but it has a special advantage particularly when it is adopted for an urban sewer system. That is, in urban areas, the pavement ratio improves and rainwater suddenly flows into sewer pipes. As a result, unpredictable rapid changes in water volume occur at the sewage treatment plant, and emergency measures are required. In such a sewer system, by adopting this embodiment, it is possible to use it as basic data of rainwater inflow prediction and various pump operations.

[0014]

According to the present invention, since the amount of rainfall is not filled with colors but is overlaid with a pattern such as shading and diagonal lines on the map information, the rainfall information does not erase the map information. Good visibility. Further, for pattern display, even when a hard copy device having a smaller number of expression colors than the graphic display device is connected, hard copy printing of the rainfall information is possible. In addition, when displaying the rainfall amount, the data is written in different layers depending on the size of the data to be displayed, so that it is possible to quickly respond to displaying only the rainfall information in a specific range, such as when displaying only the heavy rain region. .
