The design of a reminder device for placing shared bikes neatly based on attitude sensors

Bike sharing is also called “Internet Bike Rental”. The term of "sharing" implies convenience and guarantee for people with short distance commuting and low-carbon life style in every corner of the city. But what comes along is improper placement or disordered parking problem. This paper introduces a bike warning device for placement based on a jy-901 attitude sensor. The attitude judgment algorithm is used to determine the bicycle parking position and posture, and to judge whether it is properly placed. Users are reminded by a voice warning from a module to notify that the bike is not placed in order. A credit processing system is also designed to regulate random stops, dislocations and other pre-defined improper activities, and to record online simultaneously. For users whose credit is lower than the pre-set limit (e.g. 60 points), a subsequent measurements will be enacted. We are expecting that, through the direct reminder and indirect penalty mechanism development, some common parking problems for shared bikes will be alleviated.
