In order to meet 〖JP2〗the demands of a realtime automatic ground meteorological monitoring as well as an adaption to more intensive, standardized and intelligent meteorological observation, the Meteorological Observation Centre of CMA (China Meteorological Administration) has built a business prototype station at Beijing Observatory, which represents the future development of automatic ground meteorological observation. The system uses the mature and stable technology in electronic measurement, data transmission and control technology, has high reliability and high accuracy, is easy to maintain and extend. The system supports the ground meteorological data object dictionary protocol format, and the realtime observation data is sent to the ZigBee coordinator by the ZigBee wireless data transmission module. With the employment of the integrated surface observation system, the station observation data collected by an integrated hardware controller realize the quality control and application of automatically observed data.
