DISP:物联网开放式数据服务系统

DISP:Distributed Information Sharing Platform for IOT

为了使物联网中的人、机、物之间能互享数据和服务,设计并实现了DISP数据服务系统。它可以实时获取并处理数据、部署并控制设备;通过高效的稳定数据流,把系统和服务开放给所有用户,供其发布数据和共享资源,从而自由定制高级的数据组件。细述了DISP系统的架构部署、设计原理、实现机制,详细分析了实现DISP数据服务系统开放性、实时性、灵活性的关键技术,并通过实验系统验证了DISP系统的工作流程和运行效果。

For sharing data and services among human,machine and environment in the Internet of Things（IoT）,we designed a data service system,named Distributed Information Sharing Platform（DISP）.This system collects and processes a variety of data streams in real time,changing with time and location;controls devices deployed in physical environment;outputs high efficient stable data stream,serving users all over the world.Every user can either share the data stream under certain rightness,or define high-level service components as his will.This paper described the implementation mechanisms of DISP,analyzed the key techniques about real-time,openness,and scalability in detail,and verified the processes and efficiency under a prototype system.
