The core needs of emergency response work are "rapid response, efficient dispatch and real-time communication". In emergency scenarios such as earthquakes, floods and sudden accidents, communication interruption and poor information often affect emergency response efficiency and even endanger personal safety. As the core hub of emergency communication, emergency command and dispatch equipment, combined with individual soldier MESH ad hoc network equipment, UAV image transmission radio and long-distance base station type wireless transmission equipment, can build a comprehensive and full-link emergency communication system, realize real-time linkage between the emergency scene and the rear command center, and greatly improve emergency response efficiency.
