Abstract

The electromagnetic compatibility (EMC) of 400 MHz radio communications is an issue of growing interest, especially the EMC of wireless medical telemetry (WMT) in clinical settings. Electromagnetic interference (EMI) by radiation noise emitted from switched-mode power supplies built into light-emitting diode (LED) lights is now of considerable interest for the safe operation of WMT. Moreover, the 400 MHz frequency bands that are allocated for WMT are also shared and used for other radio communication systems. In this work, we studied the EMI problem of WMT used in Japan. We experimentally investigated EMI with WMT caused by electromagnetic noise emitted from LED lights. In addition, we suggested countermeasures for these EMI issues and the management of an electromagnetic environment by a very simplified method.

摘要

400MHz 无线电通信的电磁兼容性（EMC）是一个日益受到关注的问题，特别是在临床环境中无线医疗遥测（WMT）的 EMC。现在，对于 WMT 的安全运行，人们对发光二极管（LED）灯内置的开关电源辐射噪声引起的电磁干扰（EMI）非常感兴趣。此外，分配给 WMT 的 400MHz 频段也被其他无线电通信系统共享和使用。在这项工作中，我们研究了在日本使用的 WMT 的 EMI 问题。我们通过实验研究了由 LED 灯发出的电磁噪声引起的 WMT 的 EMI 问题。此外，我们通过一种非常简化的方法提出了针对这些 EMI 问题的对策和电磁环境管理。
