The invention discloses a switch loop
data extraction method, device and equipment based on
phase locking, and the method comprises the steps: carrying out the interval
change analysis of operation data in a ring main unit, and recognizing a communication abnormal node through a
phase locking technology; associating a
mechanical vibration source based on the communication abnormal nodes, detecting a vibration conduction path, extracting current fluctuation characteristics, and determining position deviation; the operation current intensity is adjusted in combination with fluctuation characteristic parameters, and accurate off-
position control is achieved through reverse braking force; constructing a dynamic threshold reference based on
frequency domain analysis, and generating a complete operation
record according to the dynamic threshold reference and the accurate parking data; performing typed grouping and transmission optimization on the data, and controlling data switching by adopting a gradually migrated beat sequence; and finally, through
signal reconstruction and data fusion technologies, a switch loop
data set with continuous
time sequence and complete space is generated. The method can effectively cope with communication interference,
mechanical vibration and other complex environmental factors, and improves the integrity and accuracy of
data acquisition.
