The invention provides a belt conveyor abnormal sound monitoring device and method, and relates to the field of signal processing, and the device comprises a disc fiber fixing seat, a sound measurement optical fiber, an optical fiber sound measurement substation and a monitoring host. The fiber coiling fixing seats are longitudinally installed along the belt conveyor and used for collecting sound signals in the operation process of the belt conveyor in a segmented mode and transmitting the sound signals to the sound measuring optical fibers between the fiber coiling fixing seats. The optical fiber sound measurement substation is connected with the sound measurement optical fiber and is used for processing segmented sound signals on the sound measurement optical fiber and transmitting the segmented sound signals to the monitoring host; the monitoring host is connected with the optical fiber sound measurement substations and is used for automatically extracting acoustic characteristics of the segmented sound si
