Frostwecker - a modern frost warning system
The fruitweb Frostwecker is a web based fros twarning system. Waether stations at the orchards measures in short intervals the wet-bulb and dry-bulb temperature and the relative humidity. The collected data are transmitted to the fruitweb server. The transmission interval depends on the type of station, but is no longer than 15 min. At the fruitweb server the collected weather data and a lokal weather forecast are used to generate a modern frost warning.
Two hours after sunset, we predict the minimum temperature in a typical radiation night (windless and cloudless sky). This forecast is updated several times at night.
Additionally it is possible to calibrate the weather forecast with local weather data (MOS), wich improves the quality of the weather forecast.
Each participant in the frost alarm can select up to three weather stations of the pool and set a personal alarm threshold for the wet-bulb temperature, dry-bulb temperature and the dew point. The warning threshold can be continuously adapted. The ongoing monitoring of temperatures and forecasts is displayed ??in tables and graphs, which has been specially optimized for viewing with a tablet PC.
The warning indication is done in several ways:
- As text message on the mobile phone or Android tablet PC
- As email with immediate warning (acoustical and optical) on the ipad
- As a phone call to the fixed network (if the call is not answered immediately, then two more calls are made)
- Direct text message from the weather station to a mobile phone (only certain types of station)
