Description

The present invention relates to a weather information providing system for providing information on weather on a computer network.

In recent years, computer networks represented by the Internet have become widely used, and various weather information announced by the Japan Meteorological Agency is provided to general users by the Meteorological Agency on the Internet. A private weather company processes the information and provides it to users over the Internet.

In recent years, the Japan Meteorological Agency has made it possible to make more local forecasts by improving the observation network and introducing numerical forecasts. As one of them, radar-Amedas analysis rainfall and short-term precipitation forecasts are distributed at regular intervals on the Japanese archipelago. It was announced as a live situation and forecast for the grid points.

The radar and AMeDAS analysis rainfall and short-term precipitation forecasts released by the Japan Meteorological Agency are published on the Internet in a format that displays a mark corresponding to the precipitation rank on the map, so general users need information In order to know the amount of precipitation at a point, it is necessary to estimate which part of the map the point corresponds to on the map, and it is necessary to prepare a map at hand in order to know the part accurately In addition, it is not possible to know the exact rainfall from the displayed rainfall rank. In addition, the radar and AMeDAS analysis rainfall and short-term precipitation forecasts distributed to the meteorological company by the Meteorological Agency via the Meteorological Operations Support Center correspond to latitude and longitude. It is difficult to know the amount of precipitation at the point you need. In addition, for general users, precipitation prediction is always necessary in daily life, but there is a drawback that information on the Internet cannot be obtained unless the computer screen is always viewed.

In the present invention, by inputting in advance the place name or zip code of the point where the user needs information, the actual condition / predicted value of precipitation at the point is predicted at the time when the point is predicted to have precipitation. The purpose is to obtain.

In order to achieve the above object, the present invention provides a weather information providing system including, firstly, a latitude / longitude table corresponding to a place name and a postal code from a numerical map of the Geographical Survey Institute and postal code data of the Postal Service. Secondly, a storage means for storing the table is provided, and thirdly, a threshold value of precipitation and a place name or a zip code for which information is desired to be transmitted by a user of the system are input. An input receiving means is provided, and fourthly, the place name or postal code obtained by the third input receiving means is compared with the latitude / longitude table stored in the second storage means so that the system user can The latitude and longitude of the point from which information is to be obtained is specified. Fifth, storage means for storing the latitude and longitude and the threshold value obtained by the third input receiving means is provided. From the latitude and longitude of the point where the user of the system memorized by the fifth memory means obtains the information, among the grid points in the radar and AMeDAS analysis rainfall and the precipitation short-term forecast announced by the Japan Meteorological Agency, The grid point corresponding to the latitude and longitude is calculated. Seventh, the radar-Amedas analysis rainfall at that grid point or the value of the precipitation short-term forecast or the original precipitation forecast based on the forecast is stored in the fifth storage means. It is proposed to provide a transmission means for transmitting the actual situation and forecast contents to the system user when the stored threshold value is exceeded.

According to the present invention, the user can input the precipitation threshold value and the place name or zip code in advance, and when the actual precipitation value or forecast value exceeds the set threshold value, the actual value and Forecast values can be obtained automatically and continuously.

Embodiments of the present invention will be described below with reference to FIGS. FIG. 1 shows a system configuration diagram according to an embodiment of the present invention. In the figure, reference numeral 1 denotes a server that provides weather information. Reference numerals 11 and 12 denote communication control units and data processing units that operate in the server 1, and 13 denotes a database in the server 1. Reference numeral 14 denotes a CD-ROM reader attached to the server 1, and a numerical map from the Geographical Survey Institute 3 can be input via the CD-ROM. The server 1 is connected to the postal service corporation 4 and the weather service support center 5 via the Internet 2. Reference numeral 6 denotes a personal computer used by a general user, which is connected to the server 1 via the Internet 2.

In the data processing unit 12 in the server 1, the latitude / longitude table creation means 12a corresponding to the place name and the postal code performs processing according to the flowchart shown in FIG. First, in step S01, it is determined whether or not a new numerical map has been published by the Geospatial Information Authority of Japan, and if it has been published, the digital map is read by the CD-ROM reader 14 in step S02. In step S03, the zip code data regularly distributed by the Postal Service 4 is acquired via the Internet 2. In step S04, the two data are collated to create a latitude / longitude table corresponding to the place name and zip code as shown in FIG. This table is stored in the database 13 as a latitude / longitude table 13a corresponding to the place name and postal code. Here, in recent years, place names are frequently changed due to integration of municipalities. Therefore, when the numerical map published by the Geographical Survey Institute 3 is updated, the latitude / longitude table 13a corresponding to the place name and postal code is updated as soon as possible. It is necessary to.

Next, in order for the user to use this system, it is necessary to input the precipitation threshold and the place name or postal code from the user personal computer 6 on the screen shown in FIG. The user information input receiving means 11a of the communication control unit 11 in the server 1 displays the screen of FIG. 4 on the user personal computer 6 via the Internet 2, and the user displays the precipitation threshold on the screen of FIG. When a value and a place name or a zip code are input, the contents are transferred from the user personal computer 6 to the data processing unit 12 via the Internet 2 and the communication control unit 11. In the data processing unit 12, the user information table creation unit 12b performs processing according to the flowchart shown in FIG. First, in step S01, it is determined whether or not there is an input from the user personal computer 6. If there is an input, in step S02, the input place name or zip code and the latitude and longitude table 13a corresponding to the place name and zip code are displayed. And the latitude and longitude of that point are specified. In step S03, a user information table shown in FIG. 6 is created from the specified latitude / longitude and the input threshold value, and stored in the database 13 as the user information table 13b.

Subsequently, the data receiving means 11b from the meteorological service support center of the communication control unit 11 in the server 1 transmits the radar and AMeDAS analysis rainfall and the precipitation short-term forecast data transmitted by the meteorological service support center 5 at regular intervals. 2 and pass to the data processing unit 12. The precipitation data analysis and user information matching unit 12c of the data processing unit 12 performs processing according to the flowchart of FIG. First, in step S01, it is determined whether there is data received from the meteorological service support center 5. If there is data, the data is edited in step S02, and the precipitation actual condition shown in FIG. And a forecast data table are created and stored in the database 13 as actual precipitation and forecast data table 13c. Here, the actual value and the forecast value correspond to each grid point, but the information on the latitude and longitude of each grid point is included in the data transmitted by the weather service support center 5 and is changed without notice. There is a possibility that it must be updated each time data is received.

In addition, when creating an original precipitation forecast using statistical methods or other methods based on the data of the Meteorological Agency's radar and AMeDAS analysis rainfall and short-term precipitation forecasts, the actual rainfall and forecast data table 13c In the forecast value, a forecast value based on a unique precipitation forecast is stored.

Subsequently, the precipitation data analysis and user information collating means 12c of the data processing unit 12 in the server 1 determines the latitude and longitude of each user in the user information table 13b in step S03 of the flowchart of FIG. Based on the actual precipitation amount and the latitude and longitude of the grid points in the forecast data table 13c, the corresponding grid point number is calculated for each user by the following formula. However, the grid point number, latitude, and longitude of each user are n (i), y (i), and x (i), respectively. In addition, the latitude and longitude of the start point of the grid point are y (s) and x (s), the latitude and longitude of the end point of the grid point are y (e) and x (e), the latitude and longitude of the grid point interval are Let Δy and Δx.

Then, in step S04, the actual precipitation value and the forecast value corresponding to the grid point are extracted from the actual precipitation and forecast data table 13c, and any one of the values becomes the threshold value of the user information table 13b. If they match or exceed, in step S05, a transmission text shown as an example in FIG. 9 is created and transmitted to the user.

As a transmission means in this case, there are a method in which data is transferred to the browser of the user personal computer 6 for display, and a method in which transmission is performed using electronic mail. In the latter case, the user of the system can receive the information with a mobile phone, a mobile terminal, etc., so that information can be obtained wherever the user is.
