摘　　要：国际电工委员会先后批准了三个过程自动化行业的无线通信标准:WirelessHART、WIA- PA和ISA 100.11a.用户曾寄希望这三个标准能够统一.虽然标准一时无法统一,但能够做到互相融合,比如说在单一架构下管理多个无线通信标准网络的实时数据.阐述了过程自动化行业无线通信标准融合的方式、可能性以及融合技术的发展现状.虽然由国际自动化学会及用户组织对过程自动化行业无线通信标准统一所做工作没达到预期目标,但来自制造商的下述工作可以看成是过程自动化行业无线通信标准融合技术获得突破的一个标志:美国尼维斯(Nivis)公司的双启动硬件、双栈无线通信模块和双栈接入点,爱默生过程管理公司的双模无线网关,霍尼韦尔公司的多协议、多应用、多标准现场无线网络.这些工作同时也证明在标准的融合方面,无线通信标准走在了现场总线的前面.The IEC has approved three wireless communication standards for the process automation industry: WirelessHART,WIA- PA and ISA 100.11a.Users had hoped that these three standards would be unified;if the standards could not be unified for a while,mutual convergence should also be achieved,such as managing real- time data of multiple wireless communication standard networks under a single architecture.The way,possibility and development status of wireless communication standard convergence in process automation industry are described.Although the unification of wireless communication standards in the process automation industry by the International Society of Automation and user organizations ultimately failed,the following work from manufacturers can be seen as a sign of a breakthrough in the convergence of wireless communication standards in the process automation industry: Nivis company s dual- boot hardware,dual- stack wireless communication module and dual- stack access point,Emerson process management company s dual- mode wireless gateway,Honeywell company s multi- protocol,multi- application,multi- standard field wireless network.At the same time,it proves that wireless communication standard is ahead of fieldbus in terms of standard convergence.
