The invention relates to a balance air cylinder pressure control module health monitoring method and device and electronic device.The method comprises the steps that balance air cylinder pressure curves and pressure deviation ranges of a brake working normally under multiple control working conditions are configured, and a normal pressure curve model is established based on the pressure curves and the pressure curve deviation ranges; respectively selecting two key feature points to establish an early warning judgment coordinate system corresponding to each control working condition based on the pressure feature data of the balancing air cylinder of each control working condition; judging the health state of a pressure control module of the brake to be detected under each control working condition by establishing a corresponding circular health state region and a circular state region to be detected in the early warning judgment coordinate system; if the pressure control module is in the healthy state under each control working condition, the pressure control module is in the healthy state. According to the invention, fault monitoring and early warning of the pressure control module of the balanced air cylinder of the brake are realized, and key information and parameters are provided for maintenance of the balanced air cylinder of the brake.
