In recent years,rapid popularity of automatic weather stations has greatly promoted the development of meteorological observations in soil and water conservation. Previous observations by artificial means on duty can not meet the needs of the development of modern soil and water conservation. Remote control and wireless data transmission of meteorological observation system are the future development trend. By combining the DAVIS Vantage Pro2 automatic weather station produced by a United States company with China Unicom CDMA1X technology,wireless remote control and remote access to automatic weather station are achieved to obtain meteorological data. Results show that the system of wireless transmission automatic weather station has many advantages,such as easy installation and use,real-time online,high-speed transmission,landing quick,affordable,and safe and reliable monitoring. Particularly in the transmission of intermittent,sudden or frequent,small amounts of meteorological data,it shows a good performance. Real-time data transmission in Fangshan County,Shanxi Province erected by CDMA1X technology-based automatic weather station with remote control terminal of Beijing Forestry University has proved that the system of wireless transmission automatic weather station can be applied to soil and water conservation and other meteorological observation fields.
