Architecture Design Of Data-Centered Smart City System And Implementation Of Android-Based Client

Under the impetus of urbanization in China,a large number of people around cities have turned into new urban residents.With the rapid growth of urban population,many problems have been exposed in cities.For example,residents feel the inconvenience caused by overpopulation in transportation,medical treatment,government affairs and other activities.The concept of "Smart City" has been put forward with the emergence of urban problems.Smart City is a new mode of urban construction and development to cope with urban management,public services and improve the efficiency of urban operation.Combined with the new generation of computer science and organically interconnecting various departments in the city,Smart City can improve the efficiency of work or operation of various departments and fields in the city.As a consequence,Smart City is conducive to the effective solution of urban problems,and it provides a new mode of urban development in the future.The core of Smart City is to realize the intelligent mode in data collection,processing,analysis and utilization,and ultimately provide intelligent information service for urban residents.At present,the theoretical research on Smart City has been relatively mature,but there are some deficiencies in the design and construction of the overall service model of Smart City.The main work of this paper is as follows:1)This paper discusses the architecture design of Smart City System,separates the data and application support layer of current Smart City System into data layer and application support layer,and designs a data-centric Smart City System architecture,expecting to provide reference for the follow-up construction of S mart City System.2)The Smart City mobile client is designed and implemented.The system mainly designs and implements the client's login registration,two-dimensional code scanning,voice recognition jump,News Center module,big data module of road condition in Smart Traffic,online medical appointment in Smart Medicine,online government information input and submission by users in Smart Government.3)This paper designs and implements some functions of the background management system of Smart City client.
