The invention relates to the technical field of spraying control, and discloses a spraying process self-adaptive adjustment method and
system based on
temperature measurement, and the method comprises the steps: presetting multi-sensor parameters, calculating a dynamic weight, calibrating sensors, and solving the problems of real-time interference and cross-process sensitivity difference; acquiring
environmental data of a target spraying process, generating a
global temperature field thermodynamic diagram, associating the film thickness with an environmental interference
label, and providing a three-dimensional reference;
coating workpiece
heat flux and empty workpiece
heat flux are collected, net
heat flux and real-
time reaction enthalpy change are calculated, a three-dimensional curing degree model is constructed, and the real-time curing degree is calculated to reflect the
coating film curing progress; based on real-time curing degree fusion temperature spatial-temporal characteristics and
phase change characteristics, core characteristics are extracted, a digital twin model is established to preview a process adjustment effect, an
optimal control vector is output by constructing a spray gun three-dimensional optimization function and an improved
quantum genetic algorithm, a targeted
actuator is triggered for regulation and control, and a
coating thermodynamic parameter
library is constructed. And updating
model parameters to optimize the overall situation.
