Infrared physiotherapy apparatus have been applied broadly as an adjunctive therapy to treat diseases.Burns always happened on patients’ irradiated parts due to the lack of controlling on radiation intensity and time during therapeutic time.Based on the characteristics of cryogenic burns of patients
a temperature controlling algorithm based on fuzzy PID is presented
and a temperature observing and controlling system for infrared physiotherapy apparatus is designed by using the MCU PIC16F877A.Experiment results show that this device can avoid burns of patients’ irradiated parts effectively.
