工业无线(无线变送器)在镇海炼化8公里乙烯运输管线项目的应用

摘要

这篇论文主要介绍了Honeywell工业无线技术在中石化镇海炼化8公里乙烯运输管线项目上的应用.该项目采用无线温度变送器实时监测管线每隔1公里的温度测点,以确保乙烯管线的正常运行.工业无线方案在管线上的应用,不仅技术先进、应用创新,而且解决了一般有线方案8公里传输的温度信号衰减的问题和安装困难的问题,也节省了大量的安装成本和调试时间,并明显降低后期维护费用,同时确保实时可靠通讯,避免因传统有线方式电缆损坏带来的通讯中断问题.本文详细阐述这个管线项目上的技术实现方案,并进一步探讨工业无线在石油炼化行业中更多的应用场合,并比较了目前无线技术应用于工业控制的2个国际标准,ISA100和WirelessHART.附件也简单介绍了霍尼韦尔公司无线架构,以及一个无线平台支持多种无线应用和多种通讯协议现场仪表的特点等.%This paper mainly focuses on the wireless application in ZhenHai Refinery 8 km enthyleve pipeline project. Wireless temperature transmitters were applied in this project to monitor the temperature measurement points every 1 kin, as a result to ensure the safe transportation operation. The advantages in installation cost saving, commission time saving, and maintenance cost reducing, and the innovative technology application brings value to this project.Two international industrial standards about wireless application in monitoring and control are compared, and in the last, explained Honeywell's OneWireless solution, which provide a multifunctional wireless network structure, that is one structure supporting multi wireless applications and multi protocol wireless instruments.
