  • This study investigates the applicability and design scheme of fieldbus network in the measurement system used for precise and safe construction as well as efficient maintenance of bridges. In order to maximize the function and performance of bridge monitoring system, this study introduces the CAN(Controller Area Network), one of the fieldbus protocols, in the measurement system of bridges. This study presents the implementation method of CAN on the monitoring system of bridge, and also proposes a bandwidth allocation scheme for the design of network. The validity of the proposed CAN design method is verified through a simulation experiment. It is shown that the CAN can be readily applicable to the measurement system of bridges.

  • Intelligent Power Switch (IPS) is a semiconductor device which contains a logic circuit in itself. It has received significant attention as a switching component to substitute the fuse and relay components in common automobile since the internal logic provides the controllability on the loads. However, a control system for the IPS status control and a network system to share the status information of IPS are required to fully exploit the capabilities of IPS. In this paper, we propose a control circuit and algorithm using IPS. Also the communication system between the control systems and IPS components using Control Area network (CAN) are proposed.

  • The growing number of electronic components used in automobiles has given rise to problems concerning the increasing number, size and weight of the wiring harnesses. As an approach to resolve these problems, multiplexed wiring systems using automotive communication protocol such as Controller Area Network(CAN), Advanced PALMNET and J1850 have been developed by many automobile companies. In order to compare these protocols quantitatively, this paper presents the performance evaluation of CAN and Advanced PALMNET via discrete event simulation. Through numerous simulation experiments, several important quantitative performance factors such as the probability of a transmission failure, average system delay(data latency), and throughput have been evaluated.

  • The load frequency control of power system is one of important subjects in view of system operation and control. That is even though the rapid load disturbances were applied to the given power system, the stable and reliable power should be supplied to the users, converging unconditionally and rapidly the frequency deviations and the tie-line power flow one on each area into allowable boundary limits. Nonetheless of such needs, if the internal parameter perturbation and the sudden load variation were given, the unstable phenomenal of power system can be often brought out because of the large frequency deviation and the unsuppressible power line one. Therefore, it is desirable to design the robust neuro-fuzzy controller which can stabilize effectively the given power system as soon as possible. In this paper the robust neuro-fuzzy controller was proposed and applied to control of load frequency over multi-area power system. The architecture and algorithm of a designed NFC(Neuro-Fuzzy Controller) were consist of fuzzy controller and neural network for auto tuning of fuzzy controller. The adaptively learned antecedent and consequent parameters of membership functions in fuzzy controller were acquired from the steepest gradient method for error-back propagation algorithm. The performances of the resultant NFC, that is, the steady-state deviations of frequency and tie-line power flow and the related dynamics, were investigated and analyzed in detail by being applied to the load frequency control of multi-area power system, when the perturbations of predetermined internal parameters. Through the simulation results tried variously in this paper for disturbances of internal parameters and external stepwise load stepwise load changes, the superiorities of the proposed NFC in robustness and adaptive rapidity to the conventional controllers were proved.

  • CAN (controller area network) suffers from data bottleneck since the number of in-vehicle electronic modules significantly increases. To mitigate this problem, CAN-FD (CAN with flexible data rate) has been proposed. Transmission speed is same with CAN in arbitration phase but much higher than CAN in data phase, which successfully achieves both compatibility and efficiency. In this paper, a CAN-FD controller was designed in Verilog HDL and it was implemented and verified in FPGA. The designed controller can perform CAN-FD version 1.0 and CAN version 2.0A, 2.0B. Synthesized in 0.18um technology, its size is about 46,300 gates.

  • Recently, the requirement of automation in the every fields of the industrial places has been increased remarkably. The shooting range systems in the Past have been designed on the basis of static circumstance. However, Various transformation of the shooting circumstances is required, since the target for real shooting situation not static. In this study we have established for targets Per one shooting line to realize the dynamic shooting circumstance, distributed shooting order into sequence and random ones. and accommodated the shooting time variably. And, we have done an efficient communication possible, using CAN(Controller Area Network) applied to a lot of the car and the building automation. The CAN can support real-time control efficiently by connecting multiple ECU(Electric Control Unit), since it provide the high data transfer rate and the stability of communication.

  • In this paper, an IEEE1588 based clock synchronization technique for CAN (Controller Area Network) is presented. Clock synchronization plays a key role to the success of a networked embedded system. Recently, the IEEE1588 algorithm making use of dedicated chipsets has been widely adopted for the synchronization of various industrial applications using Ethernet. However, there is no chipset available for CAN. This paper presents the implementation of IEEE1588 for CAN, which is implemented using only software and CAN packets without any dedicated chipset. The proposed approach is verified by the comparison between the estimated synchronization precision with a simple model and the measured precision with experimental setup.
