This invention relates to the field of industrial automatic control technology, and in particular to an intelligent control system and method for a cake production line based on machine vision feedforward and cross-process temporal decoupling. The intelligent control system for a cake production line adopts a layered architecture of industrial PC and PLC, including: a full-dimensional perception layer for collecting operating status and physical characteristic data of the controlled object, including at least a vision sensor for acquiring image data of the cake surface after baking and an infrared thermometer for acquiring surface temperature; an edge collaborative control layer, communicatively connected to the full-dimensional perception layer, including: a feature extraction unit for receiving the image data, extracting chromaticity feature values, and calculating a ripeness index in combination with the surface temperature; a temporal decoupling and compensation decision unit for comparing the ripeness index with a preset threshold and calculating the control parameter compensation amount for downstream processes based on the degree of deviation; and an instruction generation and issuance unit for superimposing the reference parameters and the compensation amount to generate control instructions.

The invention provides a real-time temperature drift compensation method and system robust to environment temperature change. The method comprises the following steps: determining N environment temperatures; the infrared temperature measuring devices are sequentially arranged in all the environment temperatures, and original temperature data are collected in real time; performing parameter fitting based on the original temperature data corresponding to each environment temperature to determine a temperature drift compensation model combination; determining the temperature excursion compensation model with the minimum fitting error average value as a temperature excursion compensation amount y16corr calculation model; a current temperature drift compensation amount y16corr is obtained based on a temperature drift compensation amount y16corr calculation model; and compensating the current infrared temperature measurement result according to the temperature drift compensation amount y16corr, and outputting a compensation result. According to the method, the temperature drift compensation amount y16corr calculation model taking the real-time shutter temperature change rate as an independent variable is constructed, so that the temperature drift compensation amount y16corr only changes along with the real-time shutter temperature, a high-precision temperature measurement result can be obtained without depending on the starting shutter temperature, and the robustness to the environment temperature change is high.
