According to the problems existing in the substation automation, this paper is study by data acquisition method of cycle distance transmission. First, Expounds the basic knowledge of CDT, including frame structure, information word, calibration method; Then, the design by hardware structure of the data acquisition system and the basic model; Finally, study by data acquisition control, including communicated methods and main attribute of MSComm control, CommEvent attribute, MSComm attribute to set, communication error setting. Using this paper of the research of design grid data acquisition software, can realize the data standardization management, improving work efficiency and economic benefit, meet the needs of enterprise modern managements. |
