In the field of industrial automation, fieldbus is changing the traditional DCS's important position and the architecture of distributed computer control system. However, it is not the time that fieldbus is popularized widely in China because of the factors of economy, technology and industrial automatic level. Therefore, this paper presents a mixed distributed computer control system that is composed of fieldbus and RS485 communication protocol. Through fieldbus and RS485, process parameters and status information of field devices are delivered to monitoring computer. In addition, the information integration between control system and management system is achieved using ODBC technology. This system has already been implemented on the product line in one large-scale tobacco group successfully. The performance results show that the system exerts the advantages of both Fieldbus and traditional data bus adequately, and has many advantages, such as openness, reliability and high ratio of capability-to-price.

Abstract. This paper presents the AEE project (Embedded Electronic Architecture), a French cooperative research and development program whose purpose is to specify new solutions for in-vehicle embedded system development. The Architecture Implementation Language (AIL_Transport) has been defined to specify and describe precisely any vehicle electronic architecture. This language supports the AEE design process, and is used by all designers as the backbone of the architecture development. Finally it is used to define reusable architecture objects.

control ENGINEERING PRACTICE 2001年第4期9卷 439-447页

作者： Campelo, JC Yuste, P Gil, PJ Serrano, JJ Univ Politecn Valencia Dept Comp Engn Fault Tolerant Syst Grp Valencia 46022 Spain

The Fault-tolerant systems Research Group of the Technical University of Valencia has developed the distributed industrial central system (DICOS) system. This paper describes DICOS nodes. The architecture of DICOS nodes and the error detection mechanisms used are presented. These mechanisms are based on the internal capabilities of the 16-bit microcontroller used and control flow checking and deadlines control with the aid of a second 8-bit microcontroller. Experimental results about the effectiveness of those mechanisms are shown in this paper. (C) 2001 Elsevier Science Ltd. All rights reserved.

IFAC Proceedings Volumes 1998年第23期31卷 93-98页

作者： Sun Yikang National Rolling Technology Engineering Researching Center University of Science and Technology Beijing

In order to satisfy the Requirement of the Fast control Cycle and Fast Communication between controllers for the Hot Strip Mill, we accept the Fiber-Optic Reflective Memory Net to connect all the controllers in one Area to compose the “Area controller Group” structure in the Basic Automation Level. The MASIC-2000 D had been used in Lai-Wu and Cheng-De Hot Strip Mill, it will be used in the 1700mm Hot Strip Mill of An-Shan Iron & Steel Corp.

The Japanese Experiment Module Remote Manipulator system is a robot system for practical use in a manned space system, the International Space Station. It is a macro-micro system of two serial 6-dof manipulators in outside the vehicle and controlled via an operation console in inside the vehicle. Numerous networked computer systems with hierarchical software play important roles supporting its management, human interface and motion control in preprogrammed and manual operations. This paper presents its system features as a highly reliable remote space robot focusing on its telematics aspect and the tele-operation capability from the ground that NASDA has been studying.

SFC++:: a tool for developing distributed real-time control software

引用

MICROPROCESSORS AND MICROsystemS 1999年第2期23卷 75-84页

作者： Martínez, XCP García, RF Univ A Coruna Dep Elect & Sistemas La Coruna 15011 Spain

This paper describes a visual tool for developing real-time control software for distributed industrial systems. The aim of this project currently in progress, is to obtain a visual programming environment which integrates both the advantages of object-oriented modelling for the design and simulation of systems and the power of modern distributed control systems (i.e. computers with real-time operating systems interconnected by means of industrial real-time networks). To bridge the gap between the object-oriented system model and the implementation level, at which we have multiple parallel tasks running on a network, sequential function charts (SFCs) are used as a standard formalism [12,16] for the description of system dynamics and control software programming.

The Comprehensive Dispatch Automation Project of Beijing Power system and the Integrated EMS SD - 6000E

引用

IFAC Proceedings Volumes 1997年第17期30卷 521-526页

作者： Z. Jin J. Liu Y. Wang X. Lu S. Mao B. Sbu G. Zbao Nanjing Automation Research Institute (NARI) China. Beijing Electric Power Bureau (BEPB) China

The traditional EMS and DMS are in fact dispatcher - oriented. The engineers in other departments such as scheduling and planning, system analysis, protective relay, etc. work with their own independent computer tools developed by different companies. The heterogeneous DB strocture and display management tools make the system maintenance very difficult. In addition, due to the uncompletely consistent power system models, the comparison and analysis of their calculated results also become difticult. The unified support software platform, conistent power system model, coordination and reasonable distribution of functions are expected. To extend the EMS/DMS to a comprehensive automation management system used by all departments of dispatch center is a feasible way. Beijing power system is the largest district system in China. NARI has taken the job of construction of the comprehensive automation system for Beijing Electric -Power Bureau. This paper introduces the system system planning, designing, developing and project scheduling.

distributed control of a Flexible Manufacturing Line: the Way of the Leading Product

引用

IFAC Proceedings Volumes 1997年第6期30卷 1367-1372页

Decision decentralization, as it is proposed here for FMS control, makes a distributed control possible, which integrates (inside each manufacturing machine) all the ”intelligence“ needed for control and coordination with the whole system. This paper shows that the decision decentralization can be realized for the scheduling layer of the control system, improving in such a way previous results obtained by the low-level control decentralization. Two policies have been implemented and tested, based for the first one on parallelized heuristic, and for the second one on scheduling rules.

Deadlock Prevention in a distributed Real-Time system

引用

IFAC Proceedings Volumes 1995年第22期28卷 123-128页

作者： O.H. Roux P. Martineau LAN (URA n°823) ECN Université de Nantes 1 rue de la Noë 44072 Nantes Cedex 03 France LESTER/IUT de Lorient 10 rue Jean Zay 56100 Lorient France

Deadlock is a circular wait condition that can occur in any multiprogramming, multiprocessing, or distributed computer system. This article focused on the second, third and fourth models of the Knapp hierarchical model called the AND-model, the OR-model and the AND/OR model. In the last model, a task is blocked until it is granted any of the resources it has requested. The classical solution for the AND-model callled the Priority Ceiling Protocol (PCP) is extended to the AND/OR-model. In the aim to extend this solution to distributed systems, the Rajkumar solution, which consists in the utilization of a global super-priority, is chosen.
