The invention discloses an intelligent terminal for removing electrocardiosignal vehicle motion noise. The intelligent terminal comprises a processor and a Bluetooth communication unit. The processor is loaded with a signal collection module, a preprocessing module, a neural network training module and a denoising module. According to the intelligent terminal, a three-axis acceleration sensor is utilized for collecting motion data as a neural network input sample, dynamic electrocardiogram data of a human body in static and moving states is preprocessed before neural network training through a format conversion and normalization method, the difference between the dynamic electrocardiogram data in the static state and the dynamic electrocardiogram data in the moving state is used for monitoring a neural network, then an artificial neural network learning algorithm is used for establishing a noise model in a proportional conjugate gradient optimizing mode, corresponding motion noise is subtracted by the dynamic electrocardiogram data obtained by monitoring, and denoising is completed. The whole equipment is simple, convenient to use and easy to realize, the vehicle motion noise can be removed automatically and effectively in the electrocardiogram monitoring process, precise electrocardiogram data can be obtained, and a guarantee is provided for diagnosis and treatment of cardiovascular diseases by a doctor.
