Research And Implementation Of Public Bicycle System Based On Cloud Database

With the development of economic and social,traffic congestion is increasing serious,the environmental pollution is also increasing,in order to reduce pollution,alleviate the pressure of urban traffic,and realizing green travel,public bicycle plays increasingly more important role.At present,the public bicycle rental at emergency response speed and processing speed slow,and the information cannot be timely and effectively transmitted to the management personnel.This article designs a public bicycle management system based on cloud data,can greatly improve the speed of information transmission.This paper designs the system of public bicycle based on the cloud database,is divided into two modules: the service platform of cloud database and the system of public bicycle.The service platform of cloud database includes interface layer,service application layer and service management layer.This paper follows the concept of cloud computing "everything is service",uses the idea of "database as a service" to design cloud database.We analysis and design the service platform of cloud database from the service,service scheduling,multi-tenant and strategy of service scheduling.Through the research on data storage and data management technology in the cloud database technology,the multi-tenant mechanism is designed,combined with the user management,contract management and service quality management technology,realizes the multi-tenant mechanism,realizes the isolation of service requests and data storage.On the basis of multi-tenant research,the scheduling strategy is analyzed,and the strategy of service scheduling based on Service Web technology is realized.The system of public bicycle based on cloud database is divided into three modules,respectively,for the control terminal module,center control gateway module and backstage management system module.The terminal control module implements public bicycle rental control.Terminal management to control the user card read and write operations to complete the bicycle rental operation,rental records uploaded to the backstage management system through CAN bus via center control gateway also acceptsthe control command from backstage management system,to complete the relevant operation.The center control gateway is the intermediate layer of control terminal and backstage management system,it is not only responsible for the communication of the control terminal and the backstage management system,but also assumed the role of the backstage management system in the case of poor network to interactive for bicycle rental and other operation with control terminal.The backstage management system includes bike management module,the card management module,system management module,statistical analysis module,the backstage management system manages the business of public bicycle,facilitates statistics and analysis of data.At the same time,backstage management system can be real-time monitoring of outlets bicycle rental.Finally,the cloud database service management platform and the system of public bicycle through the interface of API provided by cloud platform to together.Testing the realization of each module in system and performance of the system,the expected effect is achieved.
