In conventional control systems, certain send-and-receive functions are installed in the front-end processor (FEP) of the master station according to various properties of the information arriving from field terminals (FTs). The host computer reacts by sending control data to the FTs in accordance with the pre-installed optimum control algorithm, which receives transmitted information from the FEP. Our method intellectualizes a FT to be an intelligent field terminal (IFT) which judges the diverse information from devices of other FTs automatically and autonomously without depending on the host CPU or the FEP. The IFT provides multi-agent functions which can distinguish certain information conditions from other IFTs and can cooperate with the diverse functional agents of an IFT to resolve data conflicts among IFTs.","PeriodicalId":248775,"journal":{"name":"Proceedings 2000 International Workshop on Autonomous Decentralized System (Cat.

This paper shows that safety, efficiency and convenience have been improved in the areas of railway use, operations and maintenance. This is followed by a section on a new train control system for high-density lines that uses methods for transmitting information to the train about the distance to the position at which the train must stop, which is necessary for train control. This system is realized through the advanced application of information technology. Until now, it has been impossible to realize efficient operations in high-density lines due to limitations of existing signal technology. However, this has now become possible with the new train control system. The paper introduces the information technology used in this system and future developments.","PeriodicalId":248775,"journal":{"name":"Proceedings 2000 International Workshop on Autonomous Decentralized System (Cat.

Fault-tolerant protocols are used to detect faults, to mask incorrect results from faulty nodes. A task in a faulty node can he recovered through a system reconfiguration or task reallocation. A faulty node can he repaired and reintegrated into the system. This paper focuses on modelling the system under the occurrence of faults, reconfiguration and repair.

This algorithm can be used in cellular networks to estimate the mobile location from TOA information detected by several base stations (BS). The TOA number and its corresponding weight utilized in this algorithm can be dynamically adjusted according to the distance between the mobile station (MS) and serving base station. A location estimate can also be made if only the TOA and angle of arrival (AOA) are measured by the serving BS. Therefore this algorithm could be applied to most cellular networks to make the MS location estimate. Simulation results demonstrate that the location performance of this algorithm is satisfactory in three typical mobile communication channels.","PeriodicalId":248775,"journal":{"name":"Proceedings 2000 International Workshop on Autonomous Decentralized System (Cat.

ADS makes the on-line expansion fault-tolerance and on-line maintenance of the system possible. In addition, a new kind of industrial control system, the fieldbus control system (FCS) arises, which introduces the concept of communication and management in the network into the industrial control field. DeviceNet based on CAN (controller area network) was raised as one of the fieldbuses in 1998, which makes the system's integration easier and enhances the system's interoperability.
