The embodiment of the present invention discloses a laser radar wireless power supply control method and a laser radar device. The method adjusts the capacitance or inductance in the circuit structure, so that the natural frequency and the operating frequency have a large difference, and the stability of the power supply system is improved. sex. On the other hand, in this method, the fixed module and the rotating module transmit electric energy through the primary coil and the secondary coil, and realize the feedback of the working voltage through the first communication coil transceiver unit and the second communication coil transceiver unit, and realize the rotating laser through the feedback working voltage Real-time adjustment of the voltage during the radar working process to meet the power consumption requirements under three different working conditions. The wireless power supply system effectively solves the problems of poor response to large load changes, resonance frequency fluctuations caused by rotation, and low power transfer efficiency in the practical application of the laser radar power supply system, and enhances the safety, reliability, and reliability of the laser radar wireless power supply system. ease of use.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of wireless power supply, and in particular, relate to a laser radar wireless power supply control method and a laser radar device. Background technique [0002] Wireless power supply refers to the transmission of electrical energy through non-physical contact. It is a power supply technology developed by scientists at the Massachusetts Institute of Technology. The principle is to use non-radiative wireless energy transmission to drive electrical appliances. The rotating lidar is mainly used for rotating ranging. The full-angle 360-degree rotating lidar is located in the rotating part of the equipment because the laser light-emitting device and other electrical appliances are located in the rotating part of the equipment. The fixed part of the equipment must supply power to the rotating part through no connecting wires. However, the existing power supply characteristics of rotating lida...
