Fire-fighting pipe network leakage point detection system and method

The invention discloses a fire-fighting pipe network leakage point detection system and method. The method comprises the steps that a control terminal is used for responding to detection starting operation, generating a detection starting signal and sending the detection starting signal to a mobile probe attached to target detection nodes, and the target detection nodes comprise leakage point detection nodes and a plurality of environment detection points corresponding to the leakage point detection nodes; the mobile probe is used for responding to the detection starting signal, outputting vibration sound waves and receiving vibration echoes; and the server detection module is used for respectively determining target vibration data corresponding to the vibration sound waves and the vibration echoes and determining a leakage point detection result of each leakage point detection node according to the target vibration data, and the target vibration data are data representing the phase and amplitude of the sound
