摘　　要：随着YY 0505-2012标准的发布实施,医用电气设备的电磁兼容抗干扰试验的监测方法亟待研究。根据相关标准的要求,探讨了医用热垫类产品的基本性能,针对其在射频电磁场辐射抗干扰试验中温度监测这一核心问题搭建了试验模型,研究了热电偶测温法与光纤测温法在本项试验中的应用,通过温度测试的准确性和施加电磁场的畸变这两个方面结合试验数据对试验结果进行了评定,最终确定光纤测温法能够满足本项试验的要求。With the enforcement of YY0505 2012, the monitoring method of electromagnetic compatibility EMS testing for medical electrical equipment should be studied. Based on the requirements of relevant standards, this paper discusses the essential performance of mattresses intended for heating in medical use. And through the design experiments, study the temperature monitoring with thermocouple ＆ optical fiber methods in the radio frequency electromagnetic field immunity test, and evaluate the test result according to the temperature monitor accuracy electromagnetic distortion, determine the optical fiber temperature measurement method can meet the requirements of this test.
