The method includes: connecting a positioning line of a battery swapping van to a predetermined reference point of a battery-to-be-swapped vehicle; obtaining a distance between a coordinate origin of a hoister of the battery swapping van and the reference point of the battery-to-be-swapped vehicle, and angles of the positioning line with respect to a travel direction, a longitudinal direction, and a vertical direction, respectively, of the battery-to-be-swapped vehicle; and determining, based on the obtained distance and angles, a moving track of an end effector of the hoister. This application further relates to a battery swapping van configured to swap a vehicle battery, an electronic device, and a computer-readable storage medium.

Power supply system, slow-start circuit, and control method

This application discloses a power supply system, including: A first end of a bus capacitor is connected to a first end of a power supply, and a second end of the bus capacitor is connected to a second end of a semiconductor switch device. A first end of the semiconductor switch device is connected to a second end of the power supply. An input end of a power conversion circuit is connected to the bus capacitor. Two ends of a resistor are respectively connected to the first end and the second end of the semiconductor switch device. When the semiconductor switch device is switched off, the power supply supplies power to the bus capacitor by using the resistor. When a voltage of the bus capacitor is greater than a first preset voltage, an auxiliary power supply is powered on and the semiconductor switch device is switched off. When the voltage of the bus capacitor is greater than a second preset voltage, the controller controls the semiconductor switch device to be switched on, where the second preset voltage is greater than the first preset voltage. After the semiconductor switch device is switched on, the power supply supplies power to the bus capacitor by using the semiconductor switch device. The solutions help to select the semiconductor switch device with a smaller volume, reduce a volume of an entire soft-start circuit, and further reduce a volume of the power supply system.

Resource distribution method for throughput maximization in cooperative cognitive SIMO network

A resource distribution method for throughput maximization in a cooperative cognitive SIMO network. The primary user sends data after receiving a cooperation confirmation message, and the cognitive network keeps silent, receives the information data of the primary user and simultaneously decodes the data. The cognitive users which successfully decode the data send the data of themselves to the cognitive base station and forward the data of the primary user; the cognitive users which cannot successfully decode the data only send the data of themselves and do not forward the data of the primary user. The cognitive base station eliminates the interference of the data of primary user and performs beamforming for the signals. According to the combined adjustment the maximum throughput performance can be realized in the cognitive network.
