The Research And Implement Of City Mamagement And Integrated System Based On IOT

With the increase of focus of IoT, the development of IoT in China has been the high way mode.According to the requirements of IoT12th five-year development plan,Intelligent Security, Intelligent Transportation Intelligent agriculture,Smart Grid,Smart Home, Intelligent logistics and so on,will be the priority fields where IoT demonstration project is applied.In recent years,the laboratory of author has set up basic sensor network successfully,and obtain many theories and much experience in the field of IOT.Combing the existing IoT envirment of our center,this paper regards the safety monitoring,early warning, emergency response in the underground pipe network as the pointcut of demonstrate application,and realizes the function of management and safety of municipal infrastructure.In addation to this,this paper contains the description of positioning technology using current sensor network.The above two parts involve the core business functions of city management system, while all of this is based on stable,efficient,reliable data.Data collection of IOT faces the challenge of heterogeneous environment,QoS of data and semantic parsing.In order to solve these problem,this paper use a kind of middleware between business system and sensor network logically to collect data.This middleware can provide reliable semantic data for applications and is the high light of this paper. As a platform of management and monitoring,city management system contains manay valuable data,there exsit the need of using these data in department such as police, which require the city management can offer data and mutual interface to third-part system.Based on the consideration of this aspect,this paper research the application of Web Services on system integration and data mutual of city management system.Firstly, In accordance with the standard software engineering method, this paper discusses the design and implementation of city management sub-system,middle ware sub-system and information integration sub-system. Secondly,original data collecting middle ware design theory and positioning theory will be explained.Last but not least,the effect of middle ware collecting will be proved by testing.
