The invention discloses a network model checking method. The method comprises the following steps: (1) establishing hierarchy statistics and a topology structure according to an SCADA (Supervisory Control And Data Acquisition) model; (2) analyzing hierarchy and topology, carrying out statistics on user concerned information, and giving information on change of equipment in two time periods; (3) informing applications and users about the statistics and change parts. According to the network model checking method disclosed by the invention, through arranging the hierarchy statistics and the topology structure, a system can handle data in an orderly manner, checked data are relatively complete, and data which are not checked due to omission cannot exist; on the other hand, through the topology structure, the data can be in perfect order and cannot undergo a disorder phenomenon, the normal operation of the system is guaranteed, and users can conveniently look over possible problems of equipment models and process potential risk promptly.
