According to the phenomenon of “four more” and “four low” problems in the observation stations, the surface-based meteorological observing system can’t adapt to the change of the adaptive observation equipment and reduce of business intensification. A station integrated system is proposed, which can be configured, connected and extended to all kinds of observation equipment. And the integrated processor is designed, supporting a variety of communication interface standards. Flexible configuration, connection and expansion between conventional and new type of meteorological observation equipment are supported. It is capable for online calibration and maintenance of observation equipment. The effectiveness of automatic observation equipment is totally achieved to provide basic information support for disaster prevention and mitigation and national economic development.
