摘　　要：程序总线网络(Process Field Bus,PROFIBUS)协议资产是指在PROFIBUS网络中的以可编程逻辑控制器(Programmable Logic Controller,PLC)为主的硬件设备,是PROFIBUS网络中最重要的组成部分。大型PROFIBUS网络的资产分析主要目的是帮助用户更好地感知控制网络的架构与特性,已经成为了用户愈发关注的重点。然而,目前仅有少量第三方分析设备可以通过接入控制网络,提供简单的资产分析功能,无法满足用户对业务网络实现独立自主且准确的资产分析需求。因此,提出了一种PROFIBUS协议资产分析方法,通过构建知识图谱,获取资产标识,匹配网络资产,实现安全可控无偏差的资产数据自动化收集、处理和分析。通过搭建西门子和施耐德厂商不同型号PLC的实验环境,验证了所提方法的有效性、准确性和实用性。实验结果表明,该方法可以对控制网络中的PROFIBUS协议资产进行准确的识别与分析,很好地满足用户相对更复杂的需求,并创造性地填补市场空白。This paper investigates an innovative method of Process Field Bus(PROFIBUS)asset analysis based on knowledge graph.More specifically,we construct a knowledge graph to obtain asset identification,which helps us better match network assets,and finally realize the safe,controllable and accurate automatic collection,processing,as well as analysis for asset data.PROFIBUS protocol assets are the most important component in PROFIBUS network,and usually denote the hardware equipment such as Programmable Logic Controller(PLC).In practice,the asset analysis of PROFIBUS network has attracted more and more attention,however,at present,only a few third-party analysis equipment can provide simple asset analysis through access to the control network,which cannot meet the users’requirements for independent and accurate asset analysis of the production network.Therefore,this paper proposes a new asset analysis method to help users better perceive the architecture and characteristics of control network.This paper tests the effectiveness,accuracy and practicability of the proposed method by building the corresponding experimental environment of different PLC models of Siemens and Schneider.Moreover,the experimental results show that this method can accurately identify and analyze the PROFIBUS protocol assets in the control network.As a consequence,this method can greatly meet the relatively more complex needs for users,and creatively fill the gap in the market.
