This invention discloses a high-frequency response model predictive control method for a powertrain system, relating to the field of powertrain system control technology. The method includes real-time acquisition of various powertrain system data, establishment of a powertrain system model, real-time prediction of driving range based on the powertrain system model and display of driving range data, setting a driving range warning value for a kinetic energy alarm, comparing the warning value with the predicted driving range, issuing an alarm when the predicted driving range is lower than the warning value, issuing a prompt for refueling to supplement kinetic energy when the alarm is issued, having the driver confirm the refueling method, refueling the powertrain, predicting the health of the powertrain, and generating a health prediction report. This invention utilizes a high-frequency response model predictive control method for powertrain systems, supports dual modes of total driving range percentage threshold and user-defined quota threshold, distinguishes between independent warnings for pure electric and fuel-powered driving, meets the needs of different driving scenarios, provides more timely warning response, and supports automatic triggering of the refueling mode when the electric driving range is insufficient.

The application discloses a pipeline water drainage and deslagging device with filtering and fire suppression functions, which comprises a deslagging device body, a guide rod and a sound wave detector, the middle part of the top end of the deslagging device body is connected with the guide rod, and the bottom end of the guide rod is connected with a connecting seat through a limiting hole. When the pipeline water drainage and deslagging device with filtering and fire suppression functions is used, the fixed seat is automatically moved downward, so that the sealing plug is connected with the deslagging device body, the device is sealed, the gas in the pipeline is automatically cut off, the sealing property is improved through the expansion of the sealing air bag, the pipeline is automatically closed, the telescopic rod is started to drive the movable seat to move, the sound wave detector is driven to continuously detect the pipeline and the device, the staff can timely find faults, the pipeline and the deslagging device are detected, water is sprayed through the filtering copper net and the water injection pipeline, and thus the pipeline water drainage and deslagging device has the functions of filtering and fire suppression during use.
