Automatic calibration system and method for temperature transmitter

The invention discloses an automatic calibration system and method for a temperature transmitter, relates to the technical field of temperature calibration, and solves the technical problems that the corresponding preset values are different due to different current values converted from different temperature parameters, and the calibrated parameters are inaccurate if a unified preset value is adopted for calibration processing. The method comprises the following steps: acquiring a temperature parameter needing to be converted, comparing the temperature parameter with a temperature reference interval in a data packet to be processed, acquiring a corresponding reference difference value according to a comparison result, and combining the reference difference value with a current parameter to obtain a calibrated calibration parameter. The calibration parameters are transmitted into the display terminal for display processing, in the conversion process, the converted current parameters generally have errors, the
