The invention discloses an intelligent monitoring control method and
system for spraying equipment, and relates to the technical field of intelligent monitoring and
pressure control, and the method comprises the following steps: collecting
compressed air branch flow data and
pipe network node
pressure data in real time, obtaining a
pipe network topological parameter set, extracting a characteristic
frequency band energy value, and calculating a characteristic
frequency band energy value; establishing a
branch impedance model in combination with the
pipe network topological parameters, and outputting an impedance factor of each
branch through the model; if the energy value of the characteristic
frequency band is greater than the set threshold value, obtaining the position of a leakage point through a leakage
calculation algorithm, and outputting the leakage amount; and constructing a pipe network
transfer function at the output of the impedance model, predicting a pressure fluctuation envelope, and dynamically generating a
pressure control instruction according to a prediction result. According to the invention, the PID
control parameters of the
buffer tank are dynamically adjusted according to the comparison of the predicted value and the actual pressure fluctuation, so that the rapid pressure
recovery control of self-adaptive correction according to the severity of leakage is realized, and the
steady state and dynamic performance of the
system are improved.
