The invention relates to the technical field of cooperative control, in particular to a multi-
machine cooperative control method and
system for a bridge cable hoisting device, and the method comprises the following steps: collecting tension change characteristics through a distributed
sensor array, extracting indexes through a sliding window
algorithm to generate a
response time window, and generating a cooperative time window through
time sequence overlapping and speed trend adjustment. Calculating a compensation value by combining inertial parameters and acceleration to generate a trigger window, detecting tension and displacement difference, inputting the tension and displacement difference into a dynamic
threshold function for screening and fusion, outputting a synchronous trigger condition, and generating a
synchronous control instruction by encoding a device number and a tension change rate after
timestamp alignment. According to the method, multi-node tension synchronous acquisition and normalization
processing, dynamic
response generation through a sliding window, boundary matching action triggering adjustment through an overlapping
algorithm, response
lag correction through
inertia compensation, tension and displacement difference real-time detection, dynamic threshold screening and triggering condition fusion and
timestamp alignment packaging instruction consistency are carried out; and the cooperation precision and the
system robustness are improved.
