Our country is the world's largest species of meteorological disasters, activities most frequently, the most serious harm one of the countries, more than 70% of the losses caused by meteorological disasters accounted for all kinds of natural disaster losses. The various meteorological disasters affecting food production, even be able to directly affect the sustainable development of China's economic, social and ecological environment. In order to enhance the ability to improve the quantitative description of climate change and estimate the level of monitoring of global climate change and extreme weather events, there is an urgent need for good performance, high precision, long-term stable operation of the meteorological stations for long-term continuous observation of the climate system. At present, China's wired telemetry automatic weather stations more and more applications to the meteorological department. But in the harsh conditions of the mountains, deserts, islands and other areas unfit attended a large number of automatic weather stations automatic acquisition, wireless transmission (GPRS, satellite communications). With the rapid development of wireless communication technologies, especially the GPRS technology, 3G technology widely used in recent years to make the wireless transmission of meteorological data as possible. This topic is selected meteorological data collected by a GPRS wireless communication technology transfer unattended automatic weather stations. The six elements designed a GPRS-based automatic weather stations, and to achieve the meteorological elements collected automation and network. This paper first analyzes the performance and characteristics of the sensor elements such as pressure, temperature, wind direction, wind speed, humidity, rainfall, intends to develop a collection of works and various types of meteorological data sampling algorithm; details of barometric pressure, temperature, wind direction, wind speed, humidity, rainfall and signal circuit connection; final automatic weather station software system and meteorological data transmission and networking. The subject from the actual work, combined with the actual conditions of the meteorological department, the analysis of a variety of meteorological sensors collect meteorological elements principle, and through the design of data acquisition, data collection and calculation process, while taking advantage of the GPRS wireless transmission of weather data transmission to data processing center. Uniform requirements according to the China Meteorological Administration, show weather information in a standard format, processing meteorological data, so as to achieve the automatic weather station meteorological information collection, transmission and display of automation. Since the subject is able to solve the difficult conditions of the unattended areas Meteorological data acquisition, transmission problems, for the harsh conditions of high impact weather zone to solve the practical difficulties in the past, there is no meteorological information, this subject has good practicality.
