Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic weather forecasting device capable of displaying the present outdoor weather and forecasting the weather at a specific time interval in the near future and the nearby area.

[0002]

Geographic or topographical differences are generally the main reason for regional differences in weather. However, conventional meteorological forecasts include meteorological factors such as temperature, humidity, atmospheric pressure, wind speed, wind direction, etc. sensed from each meteorological station at different positions (the distance between each meteorological station may be far). Rely on collecting or planning or obtaining atmospheric cloud distribution maps from meteorological satellites, then analyzing those data by the weather station computer,
Predict. Due to technological advances, there are now computers and other computer-aided devices that are suitable for making more accurate forecasts of future weather in a wider area. Further, each forecast area may include areas of several different topography such as mountains, hills, plains, lakes, streams, seas, and the like. This allows
There were some distinctly different weather conditions in a single forecast area. To adapt to this environment or possible weather conditions in high-rise buildings or buildings, weather forecasters broadcast in some ambiguous words, such as partial cloudy, sometimes rainy or clear, to include larger areas of change. There must be. This type of weather forecast is useful for predicting rapid weather changes affecting large areas such as typhoons, cold fronts, etc., but is meaningless for local weather in special areas. And it does not give weather trends for any particular future period in any particular area.

On the other hand, the air-conditioned environment is generally separated from the outdoor environment, so that people who live indoors usually have no knowledge of outdoor weather.

[0004]

SUMMARY OF THE INVENTION The present invention is a weather forecast that provides the ability to sense outdoor weather related factors, then analyze what the future weather will look like and forecast. This device can be installed independently or installed with other devices such as air conditioners. The present invention may notify indoor or outdoor users of current weather conditions and trends. In addition, if the weather changes quickly, the present invention may generate warning signals such as audible alarms, light flashes, etc. to inform the user in advance to take corrective actions.

[0005]

The embodiments of the present invention include a number of outdoor air conditioners that periodically sense respective weather-related factors such as outdoor temperature, humidity, atmospheric pressure, wind speed and brightness. It is to install the sensor. These factors are stored in the memory unit. The microcomputer then compares and analyzes these storage factors. The local weather conditions and their changes at each current and near future time interval at the device in which this device is installed are expected and displayed on the indoor display unit.

[0006]

The structure and function of the present invention will be apparent from the following description taken in conjunction with the accompanying drawings.

FIG. 1 is a block diagram showing the structure of an embodiment of the present invention with a future air conditioner. The air conditioner of this embodiment includes a compressor 2, a condenser 3, an evaporator 6, and a motor A,
B; Fans 4 and 7; Refrigerant 5 flowing in the tube; Further, some sensors installed on the outdoor side of the air conditioner for sensing weather-related factors such as temperature, humidity, atmospheric pressure, wind speed and brightness. 15 (each sensor is mounted in a proper position to have a more precise sensing value that is not affected by the operation of the air conditioner).

These values are periodically sensed and stored in a memory unit (not shown) of the microcomputer 16. Microcomputer 16 compares the weather-related factors sensed in the most recent period (eg, the last 12 hours) with that of the corresponding period in the previous day (eg, the past 36-24 hours). By a mathematical method, the changing tendency of each weather-related factor can be represented by a time function used for deriving a change corresponding to each time interval thereafter. By adding this change to the recorded meteorological factors for each period of the previous day, meteorological factors for a period (eg, the next 12 hours) after this sensing action can be obtained and predicted. These predictions are compared with those in the weather-related factors and weather conditions table (FIG. 4) stored as a database in the microcomputer 16 to determine the weather conditions next. The result is radio 2
Via a wired connection device to a display unit, a speaker (not shown) or a remote control device 17 placed indoors or outdoors. The remote control device 17 comprises a display unit 171 and an input key set 172; here, the display unit 1
71 is used for displaying weather forecasts and other operation messages of the air conditioner, and the input key set 172 not only selects the desired information, but can also predict the weather more accurately after that. It can also be used to input the actual weather conditions into the microcomputer 16 as data for changing / correcting. Processing forecasts and changes are further described below.

FIG. 2 is a flow chart showing the operation of the microcomputer of the present invention. In step S1, the microcomputer 16 (FIG. 1) periodically retrieves the sensed values (weather-related factors) from the outdoor sensors. Step S
At 2, the memory unit of the microcomputer 16 stores the latest sensing value, and each time a new record is added, the oldest sensing value is automatically deleted to keep the updated successive record. In step S3, the microcomputer detects whether or not there is a user asking for the weather forecast; if not, the process returns to step S1; if yes, step S4 and the subsequent procedures of calculation and judgment procedure are executed. In step S4, the microcomputer compares the change in each sensed value at each time interval starting from the most recent recording back to the change from the memory unit at each corresponding interval on the previous day, as shown in FIG. : Each sensed value D (such as temperature, hence the remaining values therefore) for each time interval of the time (curve 3) in the past on the time axis T and the past 36 hours to the past 2
The values for the period of up to 4 hours (curve 1) are compared (so that the comparison of the sensed data d-4 and d-28 yields Δd-4) yielding each corresponding difference Δd of each sensed value. Then, in step S5, the difference Δd from each sensed value is calculated and included by a numerical interpolation method to produce a weather difference time function F (T). In step S6, the future time is put into the function F (T), and the future difference of its meteorological factors (curve B) is obtained, and this predicted difference with the same interval value of the previous day (curve 2) is obtained. Calculated (added or subtracted) and the new predicted value (curve 4) corresponding to the same time interval in the near future is shown. Other meteorological factors are the same. At step S7: each value currently sensed is of a weather-related factor and a weather condition (as shown in FIG. 4, this table is a reference database which can be adapted to the most general areas for a particular position or area, and the microcomputer 16 Are self-learning and modifying this table according to the instruction steps shown below), the current weather conditions are determined and displayed, checked by the user to see if they consist of actual weather, and the table above. Can be treated as a criterion. That is, in step S8, the microcomputer 16 detects whether it is instructed to change: if the user enters the actual weather conditions, the microcomputer 16 changes the table with each current sensed and calculated value. (Step S9), then go to step S10; if no command is received, then go directly from step S8 to step S10. At step S10, the weather forecast for each future time interval can be obtained by comparing each predicted future value (curve 4 in FIG. 3) with the value in the table (FIG. 4). Finally, the weather forecast is output to and displayed on the display unit via a wireless or wired connection device.

FIG. 4 is a table showing a database of weather-related factors and weather conditions according to the embodiment of the present invention. Meteorological factors include temperature and dew point (dew point can be calculated from temperature, relative humidity and atmospheric pressure), temperature change (difference between sensed or forecast value of current interval and those of last interval), relative humidity , Relative humidity difference, absolute humidity, atmospheric pressure, atmospheric pressure difference, wind speed (wind force), brightness, etc. Meteorological conditions that can be determined include: sunny, cloudy, cloudy, fog, rainy, snowy, windy, dew, frost, etc. The following example illustrates the relationship between meteorological factors and meteorological conditions so that the decision process shown in steps S7 and S10 can be better understood: Example 1: Meteorological factors affecting the current weather or some interval in the near future. Is as follows:

[0011]

[Equation 1]

At this time, each of them is compared with a table of weather-related factors and weather conditions, and it is judged that the day is sunny and the sun shines.

Example 2: Suppose the weather-related factors at some point are as follows:

[0014]

[Equation 2]

At this time, the weather becomes windy.

Example 3: Under the following conditions:

[0017]

[Equation 3]

At this time, it is judged as a rainy day.

In the above embodiment, all calculations of forecasting and forecasting are preceded by the actual user command (step S3), or the present invention allows the values to be calculated automatically on a periodic basis (in which case It can be seen that step S3 of FIG. 2 is moved between step S6 and step S7) or after the calculation of the predicted value, the predicted value of the sensed value or its change is larger than the area. That is, the present invention predicts that there will be rapid weather changes (such as typhoons, winds, storms, cold fronts, high humidity, heat waves, etc.), and the present invention provides a sound or voice alert to alert the user to Automatically give warning signal such as flash light.

As described above, the present invention can predict weather automatically and predict local weather or its changes in the near future, at present or at certain time intervals. In addition, the forecasts for this region are communicated by wire or wireless devices via a digital transmission network to other weather forecasting devices to better determine and determine the weather difference between each region and its change over time via online data transmission. Forecasting and thus forecasting for a larger area. Moreover, the display unit can be installed outdoors for general use.

Although the present invention has been described in terms of a preferred embodiment, modifications to it will be apparent to those skilled in the art. Accordingly, the scope of the invention may be determined with reference to the claims. For example, an independently configured weather forecasting device is also within the scope of the claims.
