Design And Implementation Of Application Service Subplatform Of Internet Of Things

Nowadays,the technology in the field of Internet of Things is developing rapidly,making interconnection and automation,intelligent production and life possible.Under the huge demand of various industries,the construction of the Internet of Things platform has become a hot topic.The function modules of the Internet of Things platform are complex,and the application technology is diverse.The traditional platform construction has concurrent performance bottlenecks and the data persistence efficiency is not high.Therefore,in order to create an enterprise-level platform that serves various business applications,the construction work is divided according to the Internet of Things hierarchy.The topic of this thesis is to locate the application layer in the IoT hierarchical architecture,and the purpose is to complete the design and implementation of the IoT application service sub-platform.This thesis firstly investigates the domestic and international construction achievements and the main research directions,and introduces the related technologies involved in this topic.The demand analysis of the application service sub-platform is then carried out.Focus on the demand point to complete the overall architecture design of the platform and the detailed design of each link.The design process is based on platform data aggregation,partitioning,persistence,and open interfaces.Based on Kafka message middleware,NoSQL database and other related technologies,the extension hooks,The producer consumer model,the database distributed cluster,and the RESTful Web Service interface are developed and implemented,and the platform reliability is decomposed into three aspects: data reliability,equipment reliability,and service reliability.Finally,the platform is tested for functional and performance,and the partial test is completed from the functional modules of each link,and then the system test is completed in combination with the business system.The test results show that the application service platform designed and implemented in this thesis generally meets the business requirements,and has good performance in terms of concurrent performance and platform stability.
