The present disclosure relates to the technical field of trackside acoustic diagnosis, in particular to a bearing detection system based on trackside acoustic diagnosis. The motor bearing detection system based on trackside acoustic diagnosis includes sound sensor arrays, an automatic train number identification antenna, wheel sensors, and a data acquisition host machine, where the sound sensor arrays are used for acquiring sound signals of running motor bearings; the automatic train number identification antenna is used for reading a train number and train number information of a running train; the wheel sensors are used for locating wheels, counting shafts and measuring a velocity of the running train; and the data acquisition host machine is used for processing, analyzing, counting and storing the information. By adopting array structures including no less than 12 sound sensors, the present disclosure expands a sound acquisition range, improves the accuracy of the acquired sound signals, and improves the accuracy of determining the severity of faults by transmitting the acquired information to the data acquisition host machine for comparison and analysis. Meanwhile, precise wheel location, accurate shaft counting and precise velocity measurement are achieved with cooperation of the automatic identification antenna and the wheel sensors. El C3 11
