Abstract
This application relates to a fault early warning method, apparatus, device, and storage medium for a pressure-controlled solenoid valve. The method includes setting an observation period during which the number of acquisition actions of the solenoid valve in both charging and venting states is counted. When the number of acquisition actions exceeds a threshold limit in the historical database, oscillation characteristic data is identified. Based on the oscillation characteristic data, pressure is detected on the solenoid valve in both charging and venting states. When a deviation is detected between the detected pressure change and the data in the historical database, and this deviation exceeds a threshold, a fault early warning is issued for the solenoid valve. This method is based on historical data as a benchmark, offering flexibility and adaptability to different thresholds under various environments. Simultaneously, effective data is continuously updated in the database, and with longer database iterations, the accuracy of the benchmark becomes higher.
