摘要
红外理疗仪在疾病的辅助治疗中已经得到了广泛的应用。在红外理疗过程中,对红外辐照强度和辐照时间控制不当,就会造成患者被照射部位发生烧伤。根据患者产生低温烧伤的特点,提出了一种基于模糊PID的温度控制方法,并设计了以PIC16F877A单片机为核心的红外理疗仪温度测控系统。实验表明:该装置能够有效地避免患者被照射部位发生烧伤。
Infrared physiotherapy apparatus have been applied broadly as an adjunctive therapy to treat diseases. Bums 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 bums of patients＇ irradiated parts effectively.
