A weather observation method and system based on a mobile electronic device

Abstract

The invention provides a weather observation method and system based on a mobile electronic device. The method comprises the steps of: obtaining the position data and the air pressure value of the geographic position where a mobile electronic device is located through the sensor of the mobile electronic device at the unified observation time point according to the default sampling frequency; basedon a geographic grid to which the position data belongs, comparing the air pressure value with the air pressure value obtained in the same geographical grid at the last time, and when the change amount of the air pressure value exceeds a preset threshold value, uploading the position data and the air pressure variation to a central processing device through a data communication network; and analyzing the variation of the air pressure value uploaded to the central processing device through a weather analysis algorithm, generating a weather analysis result of the geographic grid to which the position data belongs, and providing the weather analysis result through a data communication network.

Description

technical field [0001] The invention relates to a meteorological data observation method and equipment, in particular to a weather observation method and system based on a mobile electronic device. Background technique [0002] The known meteorological data are generally obtained through ground weather stations, weather observation satellites and weather radars. Ground weather stations are usually equipped with passive sensors such as barometers, thermometers, rain gauges, wind vanes and anemometers to measure Various meteorological elements. The basic meteorological elements measured by general weather stations include temperature, humidity, wind direction, wind speed, air pressure and rainfall. Weather stations can regularly perform surface weather observations and then generate and send meteorological observation data for weather analysis and forecasting. At present, there are more than 40 weather stations, weather radar stations and cooperative weather stations jointly e...

Problems solved by technology

[0007] The above-mentioned 312'patented technology adopts the method of crowdsourcing, and the first terminal collects environmental information to share the task of obtaining environmental information; the device used to collect environmental information is a special device manufactured to realize the 312'patented method. Although the system side of this method reduces the labor cost of weather forecasting and shares the equipment cost, the purchase cost of this device is completely borne by the user, and it only has a single purpose, and only a few users or specific uses It is foreseeable that the penetration rate of this special device as the first terminal of the above method is extremely low, and it should not be easy to achieve the 312' patent claim that "it can improve the coverage of environmental information collection and ensure the weather forecast. timeliness, thereby improving the accuracy of weather forecasts”
