  Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the weather information processing apparatus 20 of the present embodiment is connected to the solar power generation apparatus 10 and the user terminal 40 in various places via the communication means 50.

  The solar power generation device 10 includes a solar power generation module (panel) 11 in which a plurality of solar cells 12 are arranged on a plane, and a power conditioner that converts DC power obtained from the solar power generation module 11 into AC power. (PCS) 13, a power measuring device 14 that measures the amount of power generation, and a power receiving / transforming facility 15 that receives the AC power of the PCS and transforms it. The power measuring device 14 communicates power generation data, which is output data from the data transmission / reception unit, with the communication means 50 (solar power generation device 10 and weather information processing) in the weather information processing device 20 that collects and manages various information in this embodiment. The data is transmitted via a communication facility including a communication line between the devices 20. The photovoltaic power generation module (panel) 11 may be a combination of a plurality of modules connected in series to form a string, or a plurality of strings connected in parallel to form an array. Further, the communication line of the communication means 50 includes a public communication line such as the Internet, PLC (power line carrier communication), and the like, and includes both wired and wireless.

  The solar power generation module 11 is installed on the roof of a general house, the roof of an office building, or the like, but it is preferable to provide a rain gauge 16 adjacent to the solar power generation module 11. Since the place where the solar power generation module 11 is installed is a sunny place where there is no obstacle at the top, it is also suitable as a place for installing the rain gauge 16. As the rain gauge 16, one that can be automatically measured is used, and for example, the volume of precipitation accumulated in the water receiver is measured. The rain gauge 16 is electrically connected to the power measuring device 14 of the solar power generation apparatus 10, and the precipitation measurement data is sent from the control unit of the rain gauge 16 to the power measuring device 14, for example, at regular intervals. It is transmitted to the weather information processing apparatus 20 together with the power generation data via the communication means 50. Further, it is preferable that a thermometer and a hygrometer (not shown) are also provided and the information is also transmitted to the weather information processing apparatus 20.

  The weather information processing apparatus 20 is connected to each photovoltaic power generation apparatus 10 installed in a plurality of general houses or office buildings via the communication means 50, and communicates with the user terminal 40 of the user who performs weather prediction, such as the Internet. Connected via means 50. The weather information processing apparatus 20 is configured by a computer, and as shown in FIG. 3, a weather related data receiving means 21, a weather condition creating / outputting means 22, a forecast weather data creating means 23, a weather condition data transmitting means, which are computer programs. 24, a predicted user data receiving unit 25, a predicted user data correction unit 26, a correction result information transmission unit 27, and the like are set.

  These computer programs can be provided by being stored in a recording medium such as a flexible disk, a hard disk, a CD-ROM, an MO (magneto-optical disk), a DVD-ROM, or transmitted through a communication line. It is. In addition, the weather information processing apparatus 20 accesses the solar power generation apparatus database (solar power generation apparatus D / B) 28 that stores the position information of the solar power generation apparatus 10 in each place, and the weather information processing apparatus 20 of the present embodiment. And a user database (user D / B) 29 that stores e-mail addresses of users who use the information.

  The weather-related data receiving means 21 receives weather-related data via the communication means 50 from the solar power generation apparatus 10 and the rain gauge 16 and the thermometer attached to the solar power generation apparatus 10. Examples of the weather-related data include power generation data of the solar power generation device 10, rainfall data of the rain gauge 16, and temperature data of the thermometer. Since the rainfall data and temperature data are directly measured by the rain gauge 16 and the thermometer, etc., the received rainfall data can be directly used. However, since the power generation data is data indicating the power generation, etc. It is not a direct capture of the situation. However, according to the present embodiment, the sunshine data calculation means 221 set in the weather condition creation output means 22 described later can obtain the sunshine data from this power generation data. Received as one of weather-related data.

  The weather condition creation output means 22 uses the weather-related data received by the weather-related data receiving means 21 and uses the position information of the photovoltaic power generation apparatus 10 (which is also the position information of the rain gauge 16) that has transmitted the weather-related data to the sun. The data is read from the photovoltaic power generation device D / B 28, and weather condition data at the position at the measured time is obtained and output. For example, “XX-3, XX Town 1-2-3, Tokyo, cloudy, precipitation 0 mm” is output. Further, a weather symbol may be displayed on the installation point of the photovoltaic power generation apparatus 10 plotted on a map, or precipitation may be displayed as a bar graph or the like. Further, a weather map including the wind direction and temperature may be created and output.

  Among weather-related data, for rain data, temperature data, wind direction and wind speed data directly measured by a rain gauge 16 or a thermometer or wind direction anemometer (not shown), the weather condition creation output means 22 These data can be output together with the position information of the photovoltaic power generation apparatus 10 without performing special processing, but the power generation data cannot be used as sunshine data as it is. Therefore, the weather condition creation output means 22 is provided with sunshine data calculation means 221.

  The sunshine data calculation means 221 obtains the theoretical output value of the solar power generation device 10 in advance by referring to, for example, the longitude and latitude of the installation point of the predetermined solar power generation device 10 in advance. This theoretical output value is compared with the actual output value received as power generation data. Assuming that the theoretical output value corresponds to the sunshine intensity at the time of fine weather at a given time, find out how much the sunshine intensity (sunshine data) is based on how much the actual output value is different from the theoretical output value . The sunshine data calculation means 221 estimates sunny, cloudy, rain, etc. from the obtained sunshine intensity, compared with the value at the time of fine weather.

  The predicted weather data creation means 23 creates future forecast weather data using the weather situation data created and output by the weather situation creation output means 22. As shown in FIG. 4, for example, the forecast weather data includes character information and symbol information such as forecast date and time, forecast district, forecast weather, forecast rainfall, and forecast temperature. In addition, you may express on a weather chart like the user prediction data mentioned later (refer FIG.5 (b)). Since only the weather condition data corresponding to a certain time affects the accuracy of the forecast weather data, the forecast weather data is preferably created by referring to time series weather condition data at two or more times.

 The weather condition data transmission unit 24 transmits the above-described weather condition data output by the weather condition creation output unit 22 to the user terminal 40 via the communication unit 50. In this case, preferably, time series weather condition data of two or more times is transmitted. The weather condition data transmission means 24 reads the user's e-mail address registered in advance from the user D / B 29 and transmits it.

  When the weather status data is received by the user terminal 40, the user predicts the weather at a predetermined time in the future using the weather status data, and transmits the predicted weather to the weather information processing apparatus 20 as user predicted data. The predicted user data receiving unit 25 receives the predicted user data. As shown in FIG. 5A, for example, the user prediction data includes character information and symbol information such as user ID, prediction date and time, prediction district, prediction weather, prediction rainfall, and prediction temperature, and a user prediction data database (user Expected data D / B) 30 is registered. Further, as shown in FIG. 5B, the user prediction data may be a weather map in which a weather symbol or character information is displayed on a map of a predicted area.

  The user forecast data correction means 26 uses the forecast weather data (see FIG. 4) created by the forecast weather data creation means 23 as a model answer, and the user forecast data (see FIG. 5) received by the user forecast data reception means 25 as a model answer. As shown in FIG. 6, correction result information as shown in FIG. 6 is obtained. The correction result information is stored in the correction result total database (correction result total D / B) 31 and is transmitted to the user terminal 40 by the correction result information transmission unit 27 via the communication unit 50.

  According to the present embodiment, the power generation data is transmitted from the power measurement device 14 of the solar power generation device 10 installed at each point via the communication means 50, for example, every 30 minutes, and the rain gauge 16 The rainfall data measured and the temperature data measured by the thermometer are transmitted to the weather information processing apparatus 20, and the weather related data receiving means 21 receives these weather related data. For example, as information of 11:00, “A point in Tokyo XX ward, power generation amount (power generation data): XX kW, precipitation amount: 40 mm, temperature 25 ° C.”, “B point in XX city, Aichi prefecture, power generation Weather-related data such as “quantity (power generation data): XX kW, precipitation: 1 mm, temperature 22 ° C.” is received by the weather-related data receiving means 21.

  Next, the sunshine data calculation means 221 calculates the sunshine intensity (sunshine data) using the power generation amount (power generation data) among the weather related data. As described above, for example, the weather (clear weather, clear weather, cloudy weather, rain, etc.) at each point is relatively determined by comparing with the sunshine intensity at the time of clear weather as a reference. Thereby, for example, “A point, rain in Tokyo XX ward”, “B point, cloudy in XX city, Aichi prefecture”, and the like are determined. Then, the weather information creation output means 22 outputs the sunshine data and the rain data and temperature data as character information, or, for example, in the above example of “A point in Tokyo ○○ ward”. If there is, the weather symbol of “rain” is displayed at the position on the map corresponding to point A, and the weather condition is displayed next to it as “40 mm” precipitation and “25 ° C.” temperature as a bar graph. Create data.

  The forecasted weather data creating means 23 creates forecasted weather data using, for example, two-hour weather condition data. For example, as the information of 16:00, “A point in Tokyo XX ward” is determined to be “cloudy”, the precipitation is reduced to 5 mm from the above 11:00 point, and “B point of XX city, Aichi prefecture” ”Is judged to be“ sunny ”, and when the precipitation is reduced to 0 mm as compared to 11:00, for example, as shown in FIG. Predicting the weather at “Point A” as “Sunny, Precipitation: 0 mm, Temperature 22 ° C.”, a “Sunny” weather symbol is displayed at the position on the map corresponding to Point A, and the precipitation “0 mm” is next to it. ”To create forecast weather data.

  On the other hand, the user who has received the weather condition data at the user terminal 40 also creates the predicted weather of 9:00 the next day as user predicted data with reference to the received weather condition data. For example, the user ID No. As shown in FIG. 5 (a), ten users change the weather of “XX month × X day 9:00” and “A point in XX city, Tokyo” to “rain, precipitation: 5 mm, temperature 18 And send it to the weather information processing apparatus 20. This information is received by the user prediction data receiving means 25. Then, the user forecast data correction means 26 operates, and the forecast weather data “exemplary weather, precipitation: 0 mm, temperature 22 ° C.” of “A point in Tokyo XX ward” created by the forecast weather data creation means 23 (example) Compared with (answer), the user ID No. The 10 answer “rain, precipitation: 5 mm, temperature 18 ° C.” is corrected.

  Here, in the weather information processing apparatus 20, for example, when sunshine data is evaluated in four stages of “clear, clear, cloudy, rain”, the same case as the model answer is set to “100 points”. The difference between the evaluation table (sunshine evaluation table) and the precipitation amount is “± 1 mm: 100 points”, “± 5 mm: 80 points”, “±” Within 15 mm: 60 points ”,“ More than that: 40 points ”evaluation table (rainfall evaluation table), or for temperature, the difference from the model solution is“ within ± 1 ° C .: 100 points ”,“ ± 3 ” An evaluation table (temperature evaluation table) or the like such as “within 80 ° C.”, “within ± 6 ° C .: 60 points”, and “above: 40 points” is prepared. The user prediction data correction means 26 corrects using each evaluation table. For example, user ID No. The answer of 10 is “rainy” for the sunshine data, while the model answer is “sunny”, so it is evaluated as “60 points” as shown in FIG. Since the difference is 5 mm, it is evaluated as “80 points”, and the temperature data is evaluated as “60 points” because the difference is 4 ° C.

  Note that the forecasted weather data created by the forecasted weather data creating unit 23 and the user forecasted data created by the user are usually forecasted weather data at a plurality of points, not just one point. As described above, the overall average point, or the average point for each sunshine data and rainfall data may be obtained as a correction result (see FIG. 6). When the correction result is obtained in this way, it is stored in the correction result totaling D / B 31 and transmitted to the user terminal 40 by the correction result information transmitting means 27.

  The user can thus predict the weather and receive a result of whether the prediction is correct. Therefore, it is useful for learning the weather, learning for obtaining the qualification of a weather forecaster, and the like. Moreover, since the information obtained from the solar power generation device is used, it is useful for learning about the relationship between the amount of power generation and sunshine, and interest in solar power generation is also increased. In addition, since solar power generation devices are rapidly spreading, by selecting the region and time of the solar power generation device used for prediction, prediction of local weather changes, for example, It can also be predicted that the thunderstorm that occurred in Chiyoda Ward will also occur in the adjacent Chuo Ward several hours later.
