The invention relates to a comprehensive judging method of the operation states of equipment in a comprehensive meteorological observation network. The method includes: collecting operation state judging data which includes state data reflecting the states of the meteorological observation equipment, the observation data of meteorological factors reflecting meteorological conditions, metadata reflecting the basic information of the meteorological observation equipment, and business data reflecting maintenance support conditions; processing the state data, the observation data, the metadata and the business data to respectively form corresponding specific state information reflecting the operation states of the meteorological observation equipment; outputting the operation state display information reflecting the current operation states of the meteorological observation equipment on the basis of the specific state information. The comprehensive judging method has the advantages that the real-time operation states of the far-end meteorological observation equipment can be really reflected through a monitoring end so as to judge whether the equipment fails or not, the specific fault parts of the equipment, the fault duration and the like, and technical support and reference are provided to the maintenance support of the equipment of the meteorological observation equipment.
