Abstract

The present invention analyzes and compares the transmission of satellite images and radar images

System that informs our server of errors or modified data occurring on the network

The characteristic aspect is not to express only one persistent data

The purpose of the diagnosis is to verify the incoming data once more and inform it.

In order to do this, bidirectional Ethernet communication is required.

To check for abnormalities, and to make a call in case of absence

It is designed to enable rapid response by programming. Also server management

The program always checks the frequency of error and constructs monthly and yearly data for verification.

It's designed to be a feature.

So satellite image (512 * 512 pixels, about 104,200 bytes, GIF format) and radar image (590 * 590 pixels,

You can determine the suitability of weather information by analyzing and comparing images of about 34,500 bytes, GIF format).

It is designed to be.

Description

Satellite meteorological data comparison and analysis device {Satellite Metorologic Data Analysis}

Prior to the present invention, matters regarding the current environment and weather information

If you look at the weather bureau, you can see the aggregated data from all the regions (e.g. K-WEATER,

WEATERNEW etc ..). In this process, private operators

Provide information on weather, environment to each individual, corporation, public institution, etc.

do. As described above, in transmitting this information,

Since the suitability, validity and logic cannot be analyzed and compared, the transmitted data cannot be trusted.

It's hard to tell if you can. Therefore, the present invention is the same as the transmitted satellite image

Analyze and compare images to analyze the accuracy of the actual transmitted data.

It is displayed on the environmental status board and data due to errors or data due to loss

It also adds a function to notify the server by sending it to the management program of the server.

The present invention is a satellite image, radar image taken by the Korea Meteorological Administration to our server management program

When the data is transmitted, send the data to the environmental status board installed in each region.

The giving process is done. At this time, the image transmitted to the electronic display can be viewed in two ways.

have.

first. Original image sent by the Korea Meteorological Agency. The original image is sent to the environment board.

It is used as a data to analyze weather information of each region.

Analysis analyzes the data stored in each pixel to determine the average

The weather conditions in a certain area are divided into 16 levels and then transmitted.

If you compare it with another piece of information, it will be displayed on the status board.

If not, transfer the data to the server management program to check the data.

do.

second. The data of the original image is processed and the purpose of this image is

There is a purpose to express. The purpose of processing is generally to express color

This is because the use of LED is different from the aspect seen with CRT.

In other words, because the data applying the gamma value is represented on the electronic display board, it is processed more clearly and high quality.

In the above situation, the image is analyzed, compared and used to send it to ETHERNET.

Losing data can be read more accurately and build confidence in weather information.

Can

Hereinafter, described in detail by the accompanying drawings as follows.

The present invention provides the real-time weather and environmental information of the Meteorological Agency (FIG. 1-300)

If you send the processed data to our server management program (Fig. 1-400) every hour

The server program separates the image data from the original image (Fig. 1-401) and the processed image (Fig. 1-402).

Execute transfer to environment status board. Here, the original refers to an image sent by the Korea Meteorological Agency. This image (Figure 3) has a resolution of 512 * 512 pixels and a size of about 104,200 bytes.

The bitmap format is sent as GIF. Process files into these files,

128 * 128 pixel resolution, about 30,150 bytes in size, bitmap format is converted to JPEG

Send it. The data processed in this area is displayed on the electronic board of the environmental status board (Fig.

Express in

When data through ETHERNET 10 / 100M (Fig. 2-510) is transmitted, MCU (Fig. 2-512)

It is sequentially stored in the NAND FLASH MEMORY (Fig. 2-514) image area.

Saved data is saved separately by original or processing. After saving is completed

The MCU (Fig. 2-512) analyzes the original data. The principle of analysis is a certain area (Fig. 5-601).

If there is a value (Fig. 5-605) of the data (Fig. 5-605) based on the coordinates of the

Separating by color (Fig. 5-603), the closer to green, the "clear", white (WRITE)

Is referred to as "cloudy," and this is based on numbers like rain probability or sunny index.

By displaying the average value, more accurate information can be obtained.

The present invention is probably because it can determine the presence or absence of data transmitted from the Meteorological Agency

Data loss can be prevented in advance, and it has the characteristics to inform better weather information. In general, the boldness of the parts that represent the transmitted information

It is possible to diversify information for better analysis by comparing and analyzing in-house.

The benefits are also implied.
