| Mobile internet and public bicycles are two of the hottest topics in the world today.The Mobile Internet narrows the distance of the public and forms a huge community.People can enjoy all kinds of convenient services by using the mobile terminal to access the mobile Internet.Meanwhile,as a member of traditional public transport,public bicycles help urban inhabitants to figure out the problems of short-distance trip and become a beautiful landscape in a new environmental society.In 2016,with the introduction of "shared bicycle" into China and its rapid influx into crowded areas such as colleges and universities,living quarters and shopping centre,the new bicycle rental system based on mobile terminals has made renting bike more intelligent and convenient.Compared with swiping cards for renting bike,scanning code for bicycle rental has gradually become a trend.In addition,the traditional public bicycle system does not have a unified and reasonable management mode for the inspection,maintenance and dispatch subsystems,which will result in the disruption of information exchange and disorder of supervise among the subsystems.Therefore,for public bicycle system,it needs to build a new attitude to enter the new era of "Internet + public bicycle".This paper first analyzes the current situation and troubles faced by the traditional public bicycle system and obtains the overall plan of the new system on the basis of the business requirements and process.Moreover,based on the new system’s network architecture and interface mode,this paper designs and develops a set of high-performance server architecture that combines application server and storage server,and chooses the smart phone as the main mobile terminal device of the system.In order to facilitate the use of ordinary users and improve the efficiency of enterprise dispatchers,this paper designs a forecasting model for the storage quantity of single-site vehicles derived from the univariate linear regression model.The historical records are applied to forecast the number of bicycle storage at certain times in a day.Besides,in order to increase the efficiency of storage server,this paper designed a distributed storage server framework.The single node is decomposed into two sections: shunt forwarding and area storage,and the data is dynamically stored by identifying the area numbers of the data requests and the load capacity ofeach area server.Due to the large base of ordinary leasing users,the system uses the WeChat public platform as the mobile terminal service platform for the public bicycle rental system,and provides various leasing-related services within the platform.Considering the number of business users is relatively small,as well as the stability and convenience of the platform,the new system choose the mobile App as the mobile terminal work platform of inspection,maintenance,scheduling staff.Meanwhile,in order to ensure the normal operation of the system,the system administrator can enter the background management system through the browser to achieve data maintenance and task management.Finally,this paper tests the stability of the new system.The test results show that the new public bicycle rental management system designed in this paper performs well in stability and functionality,which can quickly response to a large number of connection requests in a short time and has a certain practicality. |
