A study for total automatic management of ME equipment by using passive RFID tag.

UHF频段（920MHz频段）无源RFID标签系统具有很高的性能。 通过使用该系统，可以在远离读取器天线的情况下识别医学个体。 本文通过实验分析了其在医院ME设备定位管理中的优势。 在医用电气设备维修中心、病房库存室和病房治疗室测量用于检测医用电气设备的标签的真实识别区域。 在实验结果中，它被认为是足够的识别区域，以检测在所有情况下的ME设备。 由于建筑物的结构使零点出现在特定的位置，因此可以预测零点的位置。 利用标签系统和医院网络系统实现了医用电气设备的远程跟踪系统。 并对电磁安全性进行了分析。 在实验结果中，确定了几类医用电气设备的安全等级。

UHF band ( 920MHz band ) passive RFID tag system has high performance. By using the system, medical individuals can be identified away from the reader antenna. In this study, its advantages are analyzed by some experiments for ME equipment location management in hospital. Realistic identification area of the tag to detect ME equipment are measured at ME equipment maintenance center, stock room in sick ward and treatment room in sick ward. In the results of experiments, it is considered that the identification area is enough to detect the ME equipment in all cases. It is also considered that null point location can be predicted, since the null point appeared at specific spot by structure of the building. Remote tracking system for the ME equipment is realized by using the tag system and hospital network system. Electromagnetic safety is also analyzed. In the result of experiments, the safety level for several category of the ME equipment are confirmed.
