This invention discloses a method for online monitoring of temperature field distribution and coordinated control of fan speed in a quick-freezing tunnel. It involves real-time acquisition of temperature data from multiple spatial sampling points within the quick-freezing tunnel to construct a dataset characterizing the spatiotemporal state of the temperature field. The dataset is analyzed to extract a first feature describing the current spatial distribution of the temperature field and a second feature describing the evolution trend of the temperature field over time. Based on the first and second features, a coordinated control command is generated to adjust the speed of at least one fan within the quick-freezing tunnel. This coordinated control command is then output to adjust the speed of each fan. This invention achieves precise coordinated control based on the global temperature field state, avoiding energy waste caused by excessive or ineffective air supply in traditional PID control or fixed-speed modes. By matching the fan speed with the actual temperature field requirements, the total energy consumption of the fan unit is effectively reduced while meeting the requirements of the quick-freezing process.
