This invention provides a condition monitoring system and method for a converter transformer single-hydrogen device, belonging to the technical field of condition monitoring for converter transformer single-hydrogen devices. To address the technical problem that existing condition assessment instruments cannot efficiently and accurately verify the accuracy of single-hydrogen devices, a simulated pipeline is installed in the middle of the side wall of the sealed cylinder, an oil inlet is installed at the lower part of the side wall of the sealed cylinder, and an oil outlet is opened at the bottom of the sealed cylinder. An electric heater and an oil thermometer are also installed on the inner wall of the sealed cylinder. An oil pressure gauge and an air bladder are installed on the inner side of the top of the sealed cylinder. The air bladder is connected to an air pump located outside the sealed cylinder via a pipeline, and a pressure relief port is also provided on the pipeline. This invention ensures controllable oil temperature and pressure during single-hydrogen device assessment, guarantees that the standard oil concentration at the oil inlet is consistent with the oil concentration detected by the single-hydrogen device, and achieves the verification of the accuracy of the single-hydrogen device.

The application discloses a mechanical structure of a flexible power-assisted exoskeleton system and a control method thereof, and the mechanical structure comprises an actuating unit box, a driving device, a main controller, a power module, an intention detection component and a power-assisted unit; the body function of a user can be enhanced under different environments, including climbing, crawling, going upstairs and downstairs; the control method is characterized in that an inertial measurement unit is fixed on each main limb of the human body, and the real-time measured limb posture data are transmitted to the main controller; the main controller performs mean filtering and preprocessing on the data, so that the credibility of the data is enhanced; the main controller obtains the corresponding human motion phase according to the posture analysis of different human motions; finally, the main controller sends a driving signal to the driving device according to a preset power-assisted strategy, and the motor rotates according to the signal, so that power assistance is achieved. The application has the advantages of simple algorithm, high real-time performance, strong stability, low hardware cost, low hardware demand and easy engineering application implementation.
