Abstract: The invention relates to the technical field of battery swapping for electric vehicles. A control method of a smart battery swapping station includes: acquiring vehicle information of a vehicle requiring battery swapping, and retrieving a model type of a corresponding battery pack locking and unlocking hole and specific parameters from a database; when the vehicle arrives at a battery swapping operation platform, capturing an image of a vehicle chassis to determine an initial pose of the vehicle chassis; processing the initial pose to extract center coordinates of the locking and unlocking hole and a normal vector direction of the locking and unlocking hole; comparing the center coordinates of the locking and unlocking hole and the normal vector direction of the locking and unlocking hole with the retrieved model type of battery pack locking and unlocking hole and specific parameters in the database to determine if the information is consistent.

Abstract: A dynamic measurement method for spatial magnetic field of transmission lines based on two-dimensional electromagnetic sensor matrix is provided. Data measured by an electromagnetic sensor matrix parallel to the transmission lines is used to calibrate an unmanned aerial vehicle (UAV) flight status, while magnetic field distribution characteristics within a profile of the transmission lines are measured using an electromagnetic sensor matrix perpendicular to the transmission lines, thereby achieving dynamic measurement of the spatial magnetic field of the transmission lines during UAV flight. The method achieves measurement of the magnetic field distribution characteristics within the vertical profile of the transmission lines while ensuring that the UAV flies parallel to the transmission lines.

Abstract: An adaptive IGBT active drive circuit is divided into two parts: a gate drive circuit, and a feedback circuit. The gate drive circuit includes a totem pole unit, and multi-level resistance switching is achieved by using a totem pole parallel structure. The feedback circuit includes a comparison unit, and a logic unit. The comparison unit includes divided resistors, sampling resistors, and a comparator. Internal currents, after passing through the sampling resistor, are compared with current comparison thresholds of complementary transistors to output a digital signal to participate in control of the totem pole. The logic unit is responsible for logically combining a PWM signal and a signal output by the comparison unit to obtain a driving signal of the totem pole.
