The invention discloses and provides a method for online calibration of an internal temperature measurement sensor of equipment. The method is simple and accurate, and online calibration can be realized without taking down the temperature sensor on the equipment. The method comprises the following steps: (1) calibrating a verification temperature measurement sensor of an external calibration device; (2) each heat preservation temperature measurement module is provided with a verification temperature measurement module; (3) the temperatures of the upper temperature measuring box, the lower temperature measuring box and the heating sheet are set to be consistent; (4) the upper computer is in communication connection with the main control board, the upper computer continuously collects the temperature values of the upper product temperature measurement sensor and the lower product temperature measurement sensor at intervals, and the main control board also continuously collects the temperature values of the veri
