The invention relates to a central detection method of a distributed data acquisition mode of a dispatching automation system. The central detection method includes: (1) collecting using conditions of hard-disc spaces, central processing units (CPU), internal storages and various hardware of all data acquisition servers of various data acquisition areas, and judging hardware states of the data acquisition servers; (2) judging operation states of the data acquisition servers; (3) judging operation states of all channels on all the data acquisition servers of the distributed type data acquisition areas; (4) judging operation states of a plant-station-end data acquisition device according to refreshing and changing states of data transmitted by a plant station; (5) storing all the states in a database, wherein the dispatching automation system can comprehensively judge operation states of system data acquisition applications according to the states. By means of the central detection method of the distributed data acquisition mode of the dispatching automation system, a unified and complete system platform is provided for users, various operation states of distributed data acquisition can be comprehensively known about in any node of the dispatching automation system, maintenance is easy, and operation is convenient.
