Design Of Intelligent Shared Bicycle System Based On Internet Of Things Technology

With the continuous development and progress of society,the way people travel has also undergone tremendous changes.As an innovative model of the sharing economy,shared bicycles have had a great impact on the way people travel.The feature of borrowing and returning has allowed more and more people to use shared bicycles,and the extensive use of shared bicycles has also played a great role in improving people’s quality of life and reducing the pressure on social public transportation.Through a large number of field and visits to investigate the status of shared bicycles,it is found that the current shared bicycle system has four shortcomings: first,most of the current shared bicycle companies are mass-produced bicycles,resulting in a certain waste of social resources;second,if If the user’s mobile phone is not carried or has no electricity,the bicycle will not be able to be used;third,the communication method mainly adopts the GSM method,which has the disadvantages of high power consumption and small number of terminals;fourth,the existing shared bicycle system often has sites "supply exceeds demand" and "Supply exceeds demand" situation.In this context,this article designs a set of shared bicycle system based on Internet technology.First of all,in response to the phenomenon of bicycle-sharing companies mass producing bicycles,this system proposes a solution for sharing individual idle bicycles.Users can share idle bicycles through mobile APP.Sharing idle bicycles can not only make full use of idle bicycle resources,but also save a lot of money for shared bicycle companies.At the same time,idle bicycle sharers can also obtain corresponding benefits,which can be described as multiple benefits.Secondly,in view of the limitation that users can only use the mobile phone to scan the code to unlock the lock,the solution of using RFID technology to swipe the card to unlock the lock is proposed.An RFID reader is installed on the shared bicycle,and then the electronic tag information read by the RFID is uploaded to the server by using NB-IoT.Swipe to unlock function.Thirdly,in view of the shortcomings of GSM,this system selects NB-IoT for data communication and realizes data transmission.Finally,Aiming at the situation of "supply exceeds demand" or "supply exceeds demand" at the site,a BP neural network algorithm is used to predict the number of bicycles to be repaid to solve the on-demand delivery and reasonable scheduling of bicycles.Set up a software and hardware test environment,and conduct a functional test of the system.Bicycle sharing function,RFID card unlocking function,mobile phone scanning code unlocking function,car return function,NB-IoT data transmission function,etc.can all run smoothly.
