The invention belongs to the technical field of communication. The invention discloses a novel emergency communication repeater communication method and system. The novel emergency communication repeater system comprises an image acquisition module, an image analysis module, a to-be-covered area determination module, a central control module, a signal receiving module, a noise reduction module, apower measurement module, a power amplification module, a filtering module, an antenna adjustment module and a signal emission module. A receiving antenna and a transmitting antenna are used for receiving and transmitting signals respectively, and the signals are subjected to noise reduction, amplification, filtering and the like before being transmitted, so that the signal strength can be enhanced, the communication quality is improved, and the communication problem of remote/disaster/imperfect construction areas is solved; the antenna angle is adjusted through the antenna adjusting module, so that the antenna can receive a signal and transmit a target area; the system is simple in structure, signal receiving and transmitting can be achieved, and reference is provided for construction ofemergency communication repeaters.
