基于无线HART的工业无线Mesh协议的设计与实现

Design and Implementation of Industrial Wireless Mesh Protocol Based on WirelessHART

无线传感器网络技术的发展和完善为工业应用提供了实施的可行性,但是工业现场环境复杂,无线技术在其中的应用一直备受挑战。通过剖析现今热门的、适用于工业环境的无线HART协议,依据无线HART的机理与应用需求,设计了工业无线Mesh协议。通过对原有TSMP协议的剖析及其对路由算法、TDMA调度算法的改进,以满足工业现场实时、可靠通信的要求。通过仿真实验以及硬件的部分实现,验证了协议的有效性和可实现性。

The wireless sensor network technology has continued to develop and its application in industry has grown significantly. However, it is challenged by the evil environment in industry field. This paper first analyzed the wirelessHART protocol, and then merited the mechanism of wirelessHART to design the industrial wireless mesh protocol according to application demand. Following that, the modified routing algorithm and TDMA scheduling algorithm based on TSMP were presented. Finally, the simulation results and hardware realization demonstrated that this protocol is able to satisfy the demands of application to industry.
