Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a weather prediction device that is installed in a familiar place such as a residence and easily predicts the daily weather.

Conventional technology In recent years, weather forecasting devices that use semiconductor pressure sensors and aneroid barometers have become popular as easy-to-use forecasting devices and have become popular, but since they mainly predict pressure, the probability of their predictions being correct is low. is the current situation. For example, a conventional weather prediction device is shown in FIG. 3 and will be described with reference to FIG. 2.

The semiconductor pressure sensor 1 detects a change in atmospheric pressure, and the atmospheric pressure storage and processing means 2 stores the atmospheric pressure as it is or stores it as an index, and determines the rise and fall limits of the atmospheric pressure. do. Based on the atmospheric pressure memory and the output from the processing means 2, the weather prediction means 3 predicts what the weather will be like in the future.
The predicted weather is displayed by the weather forecasting means 4.

In the above configuration, based on the atmospheric pressure measured by the semiconductor pressure sensor 1, the weather forecasting means 3 determines whether it is clear, cloudy or cloudy.
The weather prediction display means 4 uses liquid crystals, light emitting diodes, etc. to display rain, etc. to inform the user of future weather predictions.

Problems to be Solved by the Invention In such a conventional configuration, the weather is predicted and displayed based on the amount of change or absolute value of atmospheric pressure. Weather forecasting devices can tell whether the predicted weather is in line with the actual weather or not, and the relationship between atmospheric pressure changes and weather can be corrected according to regional and seasonal characteristics. The problem was that the weather could only be predicted using the same criteria throughout the year, which often led to errors, and that it was not very effective.

The present invention is intended to solve these problems, and aims to improve the accuracy of weather prediction by using the actual weather as a criterion when detecting atmospheric pressure and predicting the weather. .

Means for Solving the Problem In order to solve this problem, the present invention includes a semiconductor pressure sensor for detecting changes in atmospheric pressure in a weather prediction device, a pressure storage and processing means, and a current weather input device for inputting the current weather. weather forecasting means for predicting the weather upon receiving signals from the atmospheric pressure storage and processing means and the current weather input means; a weather forecasting display means for displaying the weather predicted by the weather forecasting means; and the weather forecasting means. The weather data storage means is configured to include weather data storage means for storing weather data.

Function: With this configuration, the means for storing and processing the atmospheric pressure data from the semiconductor pressure sensor stores the atmospheric pressure data, determines the rise or rising trend of the atmospheric pressure, and uses the weather forecasting means to predict the weather. Afterwards, the quality of the weather prediction is determined based on the weather input from the current weather input means, and based on this determination, data on the relationship between atmospheric pressure changes and actual weather is accumulated and fed back to the weather prediction means. This will improve prediction accuracy.

EXAMPLE An example of the present invention will be described below with reference to FIG. Note that the same reference numerals used in the prior art indicate the same components, and detailed explanation will be omitted. That is, semiconductor pressure sensor 1
The change in atmospheric pressure is detected by the semiconductor pressure sensor 1, and the atmospheric pressure storage and processing means 2 stores the atmospheric pressure value as it is or converts it into an index and stores it, thereby increasing the atmospheric pressure.

Determine the rise. Based on the atmospheric pressure memory and the output from the processing means 2, the weather forecasting means 3 predicts what the weather will be like in the future. In order to improve prediction accuracy, a current weather input means 5 is connected to the weather prediction means 3, which can input the current weather, and also stores the predicted weather and the current weather. Weather data storage means 6 is provided. Weather prediction display means 4 for displaying the weather predicted by the weather prediction means 3 is provided.

In the above configuration, weather prediction is performed, and a specific example of the contents of the weather prediction will be explained using FIG.

In Figure 2, the vertical axis shows changes in atmospheric pressure and the horizontal axis shows the passage of time. Now, suppose that the pressure change detected by the semiconductor pressure sensor 1 is a solid line indicating rain, or a broken line indicating sunny weather. However, a
The change in atmospheric pressure from point to point b is during a certain period of time Δt1,
The Δpmmb atmospheric pressure changes both in the case of rain as shown by the solid line and in the case of clear weather as shown by the broken line. In this case, if no data is stored in the weather data storage means 6, the weather prediction means 3 assumes that the prediction at point b is rain for a change in atmospheric pressure Δp during Δt. However, if the weather after Δt2 has elapsed (point C) is indicated by a broken line, it will be sunny and the prediction is incorrect, whereas if it is a solid line, it will be rainy and the prediction is correct.

Therefore, in this case, if the atmospheric pressure changes as shown by the broken line of clear weather and it becomes clear at point C, the current weather input means 5 at point C
Then input weather forecasting method 3.
recognizes that the prediction was incorrect and stores this result in the weather prediction means 6 (.And if the same pattern of atmospheric pressure changes, that is, a clear pattern like the broken line, appears, only the amount of change in atmospheric pressure We predict that it will be sunny without making any judgments.

In short, the weather predicted by the weather prediction means 3 and the actual weather are input into the current weather input means 5, the input weather and the predicted weather are compared and stored in the weather data storage means 6, and the predicted weather is By sequentially accumulating correct/incorrect information and changes in atmospheric pressure, weather predictions become more accurate.

Effects of the Invention It is clear from the description of the embodiments that the present invention incorporates the current weather input means and the weather data storage means into the weather prediction means, so that the predicted weather can be compared with the actual weather. In addition to applying feedback, it is also possible to accumulate atmospheric pressure change patterns. Therefore, unlike conventional methods that display only predictions, this system has the effect of significantly improving weather forecasting functionality by applying feedback of actual weather, accumulating weather data, and incorporating a learning function. It is.
