Folding circuit for shared bikes

Abstract

The invention provides a folding circuit for shared bicycles, which belongs to the field of circuits and includes a power supply circuit; a positioning circuit is movably connected to the first edge of the power supply circuit; a data transceiver circuit is movably connected to the second edge of the power supply circuit; The third edge of the third edge is movably connected with a communication circuit; wherein, there is a first distance between the positioning circuit and the power supply circuit, there is a second distance between the data transceiver circuit and the power supply circuit, there is a third distance between the communication circuit and the power supply circuit, and there is a third distance between the communication circuit and the power supply circuit. The first distance, the second distance and the third distance are determined by selecting the minimum space overlapping part after performing radiation simulation model processing on the folded circuit. By improving the three-dimensional structure of the hardware folding circuit, the mutual interference of receiving antennas can be avoided, and the electromagnetic compatibility capability of the receiver in a complex electromagnetic environment can be improved.

Description

technical field [0001] The invention belongs to the field of circuits, in particular to a folding circuit for shared bicycles. Background technique [0002] In the face of the severe situation of climate warming, under the call of the country for energy conservation and emission reduction, the significance of bus travel is very important. However, in the face of some short-distance, time-sensitive travel situations, the public transport system is often unable to meet the demand. The emergence of shared bicycles just made up for this vacancy. However, as the number of shared bicycles continues to increase and the number of users continues to grow, the management and use of bicycles and the protection of user travel privacy have to be put on the agenda. [0003] At present, during the use of shared bicycles, users need to receive satellite positioning signals, send and receive NFC near-field communication signals, and send and receive NB-IOT signals at the same time during t...
