英语翻译随着社会高速发展,公交自行车在用车高峰期常常出现“车多停车位少”的尴尬局面,公交自行车辅助还车系统就解决了这一问

Along with the social high speed development,bus bicycle peak often appear "jin-wei parking cars less" awkward situation,bus bicycle auxiliary car system is solved this problem,but in no parking place of the supply of power pile into question.
This article aims to design an auxiliary for the bus bicycle to return the car,the switch power supply power system for rf card reader and electronic locks provide power supply,respectively 5V and 12 v.Through to ordinary switching power supply output voltage research,analysis of the main causes of the change output voltage,which changes of switch power supply output voltage to achieve topic design requirements.
Through the circuit production and large number of experiments,TNY278 integrated chip design using the output voltage calibration,making the output voltage can achieve the research needs,this method has indeed can adjust the feasibility of switch power supply output voltage effect.
