Beidou third-generation-based double-frequency double-antenna time-frequency synchronous orientation device and method and shared bicycle

Abstract

The invention relates to the field of shared bicycle maintenance equipment, and in particular relates to a Beidou third-generation-based double-frequency double-antenna time-frequency synchronous orientation device and method and a shared bicycle. The device comprises a circuit board and a positioning module arranged on the circuit board; the positioning module comprises directional antennas used for receiving Beidou satellite signals to calibrate position coordinates, positioning chips connected with the directional antennas and used for capturing and tracking the position coordinates of the directional antennas, and a single-chip microcomputer connected with the positioning chips and used for converting the position coordinates. The directional antennas comprise at least two satellite directional antennas placed at different positions, each satellite directional antenna is connected with a positioning chip, and the same time frequency reference used for synchronous positioning is arranged between the positioning chips. According to the method and the shared bicycle scheme, double antennas and double modules are adopted, and the time-frequency synchronization reference is adopted for orientation, so that the application cost of satellite direction finding in a shared electric bicycle scene is reduced, the orientation stability is improved, and the travel safety of citizens is guaranteed.

Therefore, a method based on satellite positioning electronic fences has emerged in the industry to regulate parking behavior, but vehicles parked on the electronic fences still have inconsistent parking angles, resulting in problems such as uneven placement. There are also satellite-based single-antenna orientation, inertial However, these devices or methods are often costly and subject to environmental interference, especially the shortcoming of short-term electromagnetic interference, which affects their use on shared bicycles.
