RESUMO
To explore the electromagnetic compatibility in the shelter hospital system to adapt it to the future complex electromagnetic environment. 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. Simulations and tests proved that the failures and mal-re-sponse due to electromagnetic interference were avoided in the shelter hospital system. The electromagnetic compatibility scheme can meet the requirements of emergency medical facilities for electromagnetic protection in field conditions.
