A closed-loop paint supply system and control method based on faster-rcnn

Abstract

The invention provides a paint closed-loop supply system based on Faster-rcnn, comprising a paint pressure tank, an air supply pipeline, a proportional valve, a pressure sensor, a liquid level sensor, a paint delivery pipe, a spraying device, a mass flow meter, a fuzzy controller and PI controller, the fuzzy controller is used to carry out model training by extracting characteristic data from the mass flow expected value, obtain the optimal solution of the characteristic data, and construct the output control table according to the characteristic data and the corresponding mass flow value, and according to the given The expected value of the mass flow is obtained by obtaining the corresponding target characteristic data to obtain the corresponding opening of the proportional valve, and the PI controller is used to adjust the opening of the proportional valve. The invention combines a fuzzy controller and a PI controller to form a double-closed-loop paint supply system, which not only improves the response speed of the system, but also maintains the high precision of the system paint supply control. Correspondingly, the present invention also provides a method for controlling the paint closed-loop supply system based on Faster-rcnn.

Description

technical field [0001] The invention relates to the technical field of automation, in particular to a Faster-rcnn-based paint closed-loop supply system and control method. Background technique [0002] At present, the existing automatic paint supply system mainly uses the screw pump as the micro-drive source, controls the paint supply through different rotation speeds, and feeds back and controls the supply through the mass flow meter at the outlet. The control mode adopted is mostly a semi-closed loop Or ordinary PID, there are problems such as low responsiveness of the whole system. [0003] After a lot of searching, some typical prior art are found, such as image 3 As shown, the patent application number 201721709944.1 discloses a quantitative supply and mixing system for high-viscosity two-component coatings, which can accurately control the coating thickness on the surface of the object being sprayed, avoiding sagging, uneven spraying, etc. Problems, improve product q...
