The invention discloses a TADS-based wheel rim defect detection system, and belongs to the field of railway safety monitoring. The system specifically comprises a rail side sound acquisition module, a wheel speed measurement positioning module, a control and protection module, a data processing fault identification module and a fault networking alarm system. The rail side sound collection module collects sound of a train bearing area and sound of a train wheel and rail contact area, and the sound is sequentially subjected to signal conditioning and demodulation and then sent to the data processing fault recognition module. The wheel speed measurement positioning module obtains a wheel position signal, conditions the signal and then transmits the signal to the data processing fault identification module, and meanwhile, the array protection mechanism is controlled to start and stop. And the data processing fault identification module performs fault mode analysis and identification in combination with the fault model after deep learning, and finally forms a vehicle fault information message and sends the vehicle fault information message to a fault networking alarm system. According to the invention, the signal-to-noise ratio and effectiveness of the bearing fault sound and the wheel fault sound are improved.
