The invention discloses a real-time acquisition and storage method for key operating parameters of frequency
converters, which belongs to the technical field of frequency
converters, and comprises the following steps: aiming at the characteristics of concurrent access of
multiple frequency converters, various data types, out-of-order arrival and continuous growth, performing acquisition,
time alignment and packaging according to the data types on the operating parameters at an edge side; and a logic storage address is constructed on the center side based on the time interval, the equipment identifier and the
data type, and mapping and ordered writing of the logic address and a physical storage position are realized through a storage positioning mechanism, so that the problem that the operation data of the plurality of frequency converters cannot be uploaded under the conditions of high
concurrency and disordered uploading is solved. The technical problems of complete acquisition,
stable storage and rapid positioning query are solved, the integrity of the original operation data is ensured, the network transmission pressure is effectively reduced, storage disorder caused by an
uncertain data arrival sequence is avoided, and the
storage efficiency and query efficiency of the operation data of the large-scale frequency converter are improved.
