Research and Implementation of Data Providing Platform Based on Internet of Things

With the development of Internet of things, multi-source heterogeneous data of a large number of sensors exist in the Internet of things. How to refine and encapsulate these heterogeneous data is one of the bottlenecks in the development of the Internet of things. In this paper, the data platform uses the SpringMVC framework as the basis. The data providing platform extracts the sensor data from the database to encapsulate and transmit, which can reduce the coupling between the application layer and the underlying layer. The data providing platform provides HTTP access interfaces for the upper layer applications, the lightweight web based server push service, and publish/subscription system for multiple types of terminals. The platform not only provides multiple dimension data interfaces for the upper layer applications, but also has a high scalability. The nginx server is used to achieve the load balance, which can expand the number of servers flexibly.
