Measures for Error Avalanche and Energy Avalanche Effect in Secure Wireless fieldbus Systems

China Communications 2019年第2期16卷 202-214页

The wireless fieldbus is a vital part in present industrial automatic controls and software-defined systems. Accompanying, security is an upcoming problem determines its future leapfrog development. Wireless fieldbus systems can be made secure by encrypting the data. Unfortunately, the diffusion character of encryption brings significant vulnerabilities in terms of deteriorated error performance and energy efficiency. In this paper, we first propose an AES-dependent Hsiao(AD-Hsiao) code to improve the error correction capability, which leverages the prior information of data similarity and AES decryption to assist syndrome decoding. Then, we develop "Random Coset" scheme to reduce energy consumption. Based on mapping written data into several data candidates, this scheme lessens the number of bits written to memory and thereby boosts the write energy efficiency. Simulation results show that the AD-Hsiao code can correct majority of double errors in a single codeword with limited latency and area cost as the Hamming code. Moreover, the(72,64) AD-Hsiao code improves the reliability by 102 over the(72,64) Hamming code at 8 dB AWGN channel, and also exceeding the high cost(78,64) BCH code. In addition, the "Random Coset" improves energy efficiency by 6.6～14% than the current scheme while re-quires small ROM storage.

Networked control and supervision system based on LonWorks fieldbus and Intranet/Internet

Journal of Central South University of Technology 2007年第2期14卷 260-265页

作者：吴敏赵虹刘国平佘锦华 School of Information Science and Engineering Central South University 3. School of Bionics Tokyo University of Technology Tokyo 192-0982 Japan School of Bionics Tokyo University of Technology Tokyo 192-0982 Japan

A networked control and supervision system （NCSS） based on LonWorks fieldbus and lntranet/Intemet was designed, which was composed of the universal intelligent control nodes （ICNs）, the visual control and supervision configuration platforms （VCCP and VSCP） and an Intranet/Internet-based remote supervision platform （RSP）. The ICNs were connected to field devices, such as sensors, actuators and controllers. The VCCP and VSCP were implemented by means of a graphical programming environment and network management so as to simplify the tasks of programming and maintaining the ICNs. The RSP was employed to perform the remote supervision function, which was based on a three-layer browser/server（B/S） structure mode. The validity of the NCSS was demonstrated by laboratory experiments.

ZTE Communications 2019年第2期17卷 51-58页

作者： CHEN Jinghe ZHANG Hesheng Beijing Jiaotong University

fieldbus and industrial Ethernet standards can guide the specification andcoordinate bus optimization. The standards are the basis for the development of field-bus and industrial Ethernet. In this paper, we review complex standard systems allover the world. We discuss 18 fieldbus standards, including the International Electro-technical Commission(IEC) 61158, the IEC 61784 standard matched with IEC 61158,the controller and device interface standard IEC 62026 for low voltage distributionand control devices, and the International Organization for Standardization(ISO)11898 and ISO 11519 standards related to the controller area network(CAN) bus. Wealso introduce the standards of China, Europe, Japan and America. This paper pro-vides a reference to develop fieldbus and industrial Ethernet products for Chinese en-terprises.

第二届仪器科学与技术国际学术研讨会

作者： Shi Fuyuan Ma Xiushui Automation Department Anhui University

＜正＞ The technical characteristics and advantages of fieldbus, and the way out of its further developing are idscussed. The main technical merits of ethernt, and some of its demerits in the industry control field applications are also investigated .The paper analyses the possibilities of the technical merging of both fieldbus and ethernet in industry control applications is analysed, and the brilliant prospect for the merging of these two technologies is nointed out. Several technical routes to merge the two, such as extending ethernet to the industrial control fields, merging the two communication protocols, and developing an unified industrial ethernet standard, etc. are reviewed.
