Abstract

PURPOSE:To display a meteorological data on one and same display pattern simultaneously by combining a picture distributed from a meteorological satellite and a picture by a meteorological radio facsimile information so as to obtain the pattern. CONSTITUTION:A meteorological data signal from a meteorological satellite is acquired by an antenna 1 for receiving a meteorological satellite distribution signal and received and demodulated by a meteorological satellite distribution signal reception section 2 and stored in a meteorological satellite picture memory 6. On the other hand, a meteorological radio facsimile information signal is fetched by a meteorological radio facsimile information signal antenna 3, received and demodulated by a meteorological radio facsimile information signal reception section 4 and stored in a meteorological radio facsimile information picture memory 7 of a picture processing section 5. Both the pictures stored in the picture memories 6, 7 are constituted into the picture subject to position correction including the coordinate conversion at the synthesis section 8 with the meteorological satellite picture and and the meteorological radio facsimile information picture. Thus, it is possible to observe both the pictures simultaneously on one and same pattern and new information is obtained momentarily by combining the different pictures on the one and same pattern.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a weather image reception and display device that processes and displays weather image data received wirelessly.

[Conventional technology]

In the past, images from low-resolution facsimiles and weather radio reproduction reports were displayed or printed separately and used for weather analysis.

[Problem that the invention seeks to solve]

Images of cloud distribution and temperature information obtained by the above-mentioned low-resolution facsimile, and images of atmospheric pressure, wind direction, and wind speed obtained by weather radio reproduction notifications were displayed or printed separately and used for meteorological analysis, etc. However, it is not possible to view both images at the same time, and operations are performed by comparing the images alternately.This has the drawback that operations such as confirming the location of a weather phenomenon require judgment by the operator and are labor-intensive.

SUMMARY OF THE INVENTION An object of the present invention is to provide a weather image receiving and displaying device which eliminates such drawbacks and can simultaneously display weather data on the same display screen.

[Means for solving problems]

The meteorological image receiving and displaying device of the present invention has a first receiving means that receives a low-resolution facsimile signal transmitted from a meteorological satellite and demodulates it as an image signal, and stores the image signal from the first receiving means. a first image memory; a second receiving means for receiving a weather radio reproduction report transmitted by shortwave radio and demodulating it as an image signal; and a second image memory for storing the image signal from the second receiving means. , an image synthesizing means for positionally correcting and synthesizing each signal from the first and second image memories, and an image display means for displaying the output of the image synthesizing means on the same screen. shall be.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a weather image receiving and displaying device according to an embodiment of the present invention. A meteorological data signal from a meteorological satellite is captured by a meteorological satellite distributed signal receiving antenna 1, received and demodulated by a meteorological satellite distributed signal receiving section 2, and then stored in a meteorological satellite image memory 6 of an image processing section 5. Ru. On the other hand, the weather radio reproduction report signal is taken in by the weather radio reproduction report signal antenna 3, received and demodulated by the weather radio reproduction report signal receiving unit 4, and then used as a weather radio reproduction report image by the image processing unit 5. It is stored in the memory 7. Both images stored in the image memory 6.7 are constructed after being subjected to position correction including coordinate transformation in the meteorological satellite image and meteorological radio reproduction report image combining unit 8.

The following four methods can be used as this image synthesis means.

The first image synthesis means, as shown in the schematic diagram of FIG.
This is a method of embedding weather radio reproduction report images into meteorological satellite images. "11..." At the same position of the meteorological satellite image data 11 that cannot be expressed in the pattern "2, 2..."
If there is meteorological radio reproduction report image data 12 represented by Embedded to obtain image composition.

The second image synthesis means, as shown in the schematic diagram of FIG.
This is a method that changes the meteorological satellite image data when the information of the meteorological satellite image and the weather radio reproduction report image overlap. Meteorological satellite image data 11 expressed as "11..."
If there is weather radio reproduction report data 14 expressed as "1, 1..." at the same position as a certain position, by inverting this meteorological satellite image data 14, the weather radio reproduction report image data 11 can be expressed on the meteorological satellite image data 14, and an image composite thereof can be obtained. In addition to data inversion, this image synthesis means can perform image synthesis by changing image data by addition, subtraction, multiplication, and division of quantitative values.

As shown in the schematic diagram of FIG. 4, the third image synthesis means is a method of image synthesis of a meteorological satellite image and a weather radio reproduction report image at the stage of image display. , image data is displayed as a composite of the three primary colors consisting of red, green, and blue. In this case, the meteorological satellite image data 11 and the meteorological radio reproduction report image data 12 are input to the image display section 9 as data for different three primary colors among the three primary colors of red, green, and blue. In this case, the meteorological satellite image data 11 and the meteorological radio reproduction report data 12 are combined on the color image display section 9 and displayed in different hues, so a composite image 16 is obtained by combining these colors. It will be done.

The fourth image synthesis means, as shown in FIG. 5, is a method of creating data having information on both a weather satellite image and a weather radio reproduction report image. That is, assuming that the data per 1 pixel of the meteorological satellite image data 17 has an information amount of m bits, and the data per 1 pixel of the weather radio reproduction report image data 18 has an information amount of n bits, the data area after combining these images is can store m+n bits of information data 19 per pixel. In this case, the data area after image synthesis has an arrangement of (m + n) bits or an arrangement of (n+m) bits, and these are stored to obtain image synthesis.

The image display synthesized by the image synthesis means in this way is
This is performed in the image display section 9, and the image is printed in the image printing section 10.

〔Effect of the invention〕

As explained above, the weather image receiving device according to the present invention can simultaneously observe both images on the same screen by combining the meteorological satellite distribution image and the image from the weather radio reproduction notification to obtain a screen. By combining different images on the same screen, new information can be obtained instantly.
