摘要
现有无线传感器网络主要工作在分布式系统下,难于管控。为了解决无线传感器网络在工业应用中所面临的挑战,基于Wireless Hart工业无线传感器网络标准提出集中控制的思想,研究设计适合工业无线传感器网络系统控制与数据转发分离的网络架构,并且设计实现符合Wireless Hart标准的TDMA时隙调度算法。文中提出的网络构架和时隙调度算法可以根据工业应用的业务需求灵活分配通信资源。从而减轻节点设备的处理压力,提高节点的灵活快速响应能力,实现可靠实时的工业无线传感器网络。
The existing wireless sensor networks mainly work in distributed systems, which is hard to control. In order to address the challenges of wireless sensor networks in industrial applications, based on WirelessHart industrial wireless sensor networks standard, the centralized control thinking is proposed,research and design a network architecture for industrial wireless sensor network system control and data forwarding separation, and the TDMA slot scheduling algorithm is designed to achieve compliance with the standard WirelessHart. Network architecture and slot scheduling algorithm proposed in this paper can flexibly allocate the communication resources according to business needs of industrial applications, thereby relieving the pressure of node processing equipment, improving flexibility and fast re- sponse capability of nodes, achieving reliable and real-time industrial wireless sensor networks.
