  • Research on Safe Communication Architecture for Real-Time Ethernet Distributed Control System
    IEEE Access, 2019
    Co-Authors: Zhengyu Huang, Xianliang Jiang, Lingyu Chen
    Abstract:

    With the penetration of real-time Ethernet in industry, the mechanism of CANopen protocol based on real-time Ethernet (COE) has been widely used in various Distributed Control Systems. However, due to some defects of the existing COE mechanism, the functional integrity and security for communication could not be guaranteed. Thus, Safe-COE architecture is designed in this paper. First, safe communication problems in Systems are analyzed. Then, based on the Security and Safety Modeling (SESAMO) method, safe building blocks for communication are designed and combining these building blocks with Safe-COE mechanism, a kind of Safe-COE communication architecture is proposed. Finally, communication performance is tested based on this architecture. The results show that based on the general Ethernet MII bus interface, the minimum communication cycle could reach 125 μs , and the minimum synchronization accuracy of peripherals Control could be about 100 ns. Moreover, the formal modeling method is used to verify the safe integrity of this architecture. The results show that the architecture could meet related safe requirements of attack protection, data validation, disconnect monitoring, and state switching. Currently, there is no safe communication architecture for a Distributed Control System that could fully meet related standards and consider both functional safety and information security. It could provide a theoretical basis and solution for safe communication in the Distributed Control System.

  • Distributed Control System of humanoid robots based on real time ethernet
    Intelligent Robots and Systems, 2006
    Co-Authors: Fumio Kanehiro, Y Ishiwata, H Saito, Kazuhiko Akachi, Go Miyamori, Takakatsu Isozumi, Kenji Kaneko, Hirohisa Hirukawa
    Abstract:

    In this paper we realize a real-time communication on Ethernet and develop an onbody Distributed Control System for a humanoid robot, HRP-3P. Real-time communication on Ethernet is realized by (1) a communication method using the data link layer directly and (2) timing Control using a real-time operating System ARTLinux. This enables us to reduce the cost of embedded Systems and improve developmental efficiency. A CORBA implementation which works on this communication layer is also developed to increase compatibility with existing software. Finally a small-size Distributed robot Controller is developed for the onbody network of HRP-3P and a Distributed I/O System is developed on top of this.
