基于RTSJ的物联网智能网关研究

物联网网关发挥着连接传统信息网络与感知网络的重要作用,针对目前人们使用过时的开发手段实现物联网网关软件的设计,提出了一种使用实时Java技术的实现方案。系统以ARM Cortex-A57架构的AMD Opteron 1150处理器为核心构建物联网网关系统硬件平台,采用"互联网+传感网技术/现场总线"的组网方案实现有线/无线的数据交互,使用完全兼容RTSJ的WebSphere Real Time开发平台实现物联网网关协议的转换,以及三层网络间通信软件的设计,保障物联网网关的安全实时通信,最后给出了该设计的实现技术和系统验证。结果表明:RTSJ很好地保障了Java语言的实时性,整个物联网智能网关完全符合实时系统应用程序的毫秒级测量精度和所期望的服务质量要求。

Research on Intelligent Gateway of Internet of Things Based on RTSJ

The Internet of things gateway plays an important role in connecting the traditional information network and the perception network. Aiming at the current use of outdated development tools to implement the design of gateway software for the Internet of Things, an implementation scheme using real-time Java technology is proposed. The system uses the AMD Opteron 1100 processor with ARM Cortex-A57 architecture as the core to construct the IoT gateway system hardware platform. The networking scheme of "Internet + sensor network technology/field bus" is adopted to realize the data interaction of wired/wireless. The WebSphere Real Time development platform fully compatible with RTSJ implements the transformation of the iot gateway protocol, as well as the design of two layers of internetwork communication software. The security and real-time communication of the Internet of things gateway is guaranteed. Finally, the implementation technology and system verification of this design are given.
