摘　　要：目的:对方舱医院系统进行一系列的电磁兼容设计,用于对抗未来复杂电磁环境下的电磁干扰问题。方法:分析造成系统电磁干扰的因素,提出了分开放置干扰源与敏感设备、设置屏蔽空间隔离不同设备、利用良好接地保护敏感设备、使用滤波技术去除骚扰信号等措施,并通过电磁自兼容试验和外部射频电磁环境适应性测试对方舱医院电磁兼容性进行了检测。结果:通过电磁兼容仿真和试验检测,该方舱医院系统基本消除了由电磁干扰所引起各分系统或设备的故障及不容许的响应,达到了系统的电磁兼容要求。结论:该方舱医院系统的电磁兼容设计方案可满足野战条件下应急医疗救治机构电磁安全防护的需要。Objective To explore the electromagnetic compatibility in the shelter hospital system to adapt it to the future complex electromagnetic environment. Methods The factors for electromagnetic interference were analyzed, and some measures were put forward including separating the interference source from the sensitive device, setting up shielding space, applying grounding measures, eliminating interference signals by filtering and etc. The electromagnetic compatibility in the shelter hospital system was detected through electromagnetic self-compatibility test and electromagnetic environ-mental suitability test for external radio frequency. Results Simulations and tests proved that the failures and mal-re-sponse due to electromagnetic interference were avoided in the shelter hospital system. Conclusion The electromagnetic compatibility scheme can meet the requirements of emergency medical facilities for electromagnetic protection in field conditions.
