Research on Emergency Call System Adaptability to Actual Electromagnetic Environment

Research on the performance of emergency call system in the actual electromagnetic environment is of great significance to ensure the reliable operation of the system. Based on the analysis of the emergency call system connectivity and communication quality, the actual electromagnetic environment signal collection and playback are carried out, and the connectivity and communication quality of the emergency call system in actual electromagnetic environment are tested and verified. The test results show that some performance indicators of the emergency call system will be affected by the actual electromagnetic environment signal, which provides a reference for the electromagnetic compatibility quality assessment of emergency call system and the formulation of relevant standards.
