Design And Realization Of The Platform For Sensor Data Processing On Internet Of Things

With the development of IoT technology, all walks of life begin to use IoT technology to realize the intelligent operation of various types of information. But because of the low compatibility between different IoT platforms, a lot of unnecessary duplication may be resulted in a great waste of human and financial resources. On the other hand, for some small and micro enterprises and individual entrepreneurs with less funding, time or technology, may not be able to develop a professional IoT service platform.To addres above problems, an IoT platform is fully researched in this thesis, aiming for a unified management and configuration to achieve real-time monitoring and analysis of sensor data collection. At the same time, in order to improve the personalized service on the platform, we implement an XML language based configuration mechanism to customize the communication according to different protocols. Therefore, the main work is as follows:(1) Proposing clarifying the adavatage to integrate SSH framework with MINA server for buiding the platform. The IoT platform is divided into two major parts:web management system and data communication system,integtating the service layer to interact with the database. Through the Web management system, the user can customize communication protocols, manage device information, view the analysis of collected data, modify personal information, and publish news bulletin. Meanwhile, sensor data communication system is responsible for parsing and persisting data for Web query calls.(2) Using SSH technology to build Web management system. The Web management system is divided into five modules. A common module is achieved and designed from the perspective of MVC hierarchical. Then the five modules are detaily designed to satisfy the configuration of communication in this part. Meanwhile, the support of HTTP request is desgined in web server, in order to communicate with the device which can transfer data with HTTP protocol.(3) Using MINA technology to build sensor data communications systems. Data communication system is designed to communicate via TCP / IP protocol, focusing on the communication processing and analysis of binary sensor data as the configured communication protocol.(4) Using the asynchronous processing method of sensor data to optimizae the performance of the communication system. And the functional characteristics of the sensor data processing Io T platform is verified based on this.The IoT platform can fulfil requirements of various types of sensor data communication. And it has the ability to implement user management, device management, custom communication protocols, sensor data monitoring and analysis capabilities, with some versatility.
