The invention discloses an automobile
assembly line communication coordination
system and method based on an
industrial network, and relates to the technical field of communication coordination, and the method comprises the steps: calculating a single
welding quality score Q in real time for an edge calculation node located at each
welding station, generating a
welding event
fingerprint, and carrying out annular caching; determining whether to upload the high-resolution data and the original waveform to a rear end based on a threshold value and the calculated joint anomaly
score;
qoS management is carried out on the
control flow and the quality return flow; welding event fingerprints reported by the edge are received,
backtracking data are stored, a network-quality joint
causal analysis model is executed, and model updating is issued; and according to a
causal analysis result and a
historical model, implementing automatic welding parameter
fine tuning, repair welding triggering, local redundancy switching and
rollback strategies. According to the method, the problems that the
welding process is extremely sensitive to
delay jitter and intermittent welding defects and
traceability data missing are caused by high-resolution
quality data backtracking in an existing automobile
assembly production line industrial network are solved.
