Temperature field measurement and control system and method based on finite element simulation

The invention belongs to the technical field of temperature measurement and control, and particularly relates to a temperature field measurement and control system and method based on finite element simulation. The system comprises a heating unit, the heating unit comprises a metal vessel, and the metal vessel is filled with a conductive powder bed composed of conductive powder; the conductive unit comprises two groups of electrodes capable of moving oppositely or oppositely, the two groups of electrodes are wrapped in a conductive powder bed, and a sample is placed between the two groups of electrodes; and the monitoring unit monitors the global temperature of the conductive powder bed. According to the method, a real-time temperature field distribution image is obtained based on a finite element simulation model and is compared with an actually-measured conductive powder bed global real-time temperature field, and the input current or the electrode spacing of electrodes is controlled according to deviation
