A kind of electric power scheduling automatization system multi-source data check method, comprises the steps:
S01: the ID that the unique designation of each measuring point in electric power scheduling automatization system is set, parameter and the information table of each passage are set, wherein, namely the data ID of the image data of different passage same observation station is the ID of measuring point, and namely the data ID of the image data of different passage same observation station is identical;
Wherein, channel parameters comprises communication modes, communication protocol, transmission communication transmission rate etc., and information table comprises remote measurement in passage, the ID of remote signalling, title, communication period, and the base value of remote measurement process and coefficient, the polarity etc. of remote signalling process, wherein data ID is that system is automatically generated.
