  • In this paper, we want to able to reduce the time effectively about the analysis of protocol and development of protocol converter in industrial network. For this purpose, we developed the user protocol converter that can be to analysing the communication protocol in the industrial network. and also that is able to converting to user protocol and transmitting to another network. The developed user protocol converter was consist of S/W and H/W, and is supporting the Modbus, the NMEA0183 and the ethernet. The hardware main processor was used the AVR128, and placed the serial communication part and the ethernet part in converter board. The experiment results, we acquired very high transmission rate and conversion rate.

  • This study aim is to effectively reduce the time that was required for the analysis on an existing communication protocol with the industrial monitoring equipment. We analyzed the collected data with the Modbus protocol and NMEA0183, which is widely used in industrial monitoring. and User will be easy converting to data for use on each devices. The main board of the protocol converter was used AVR128, and RS232C and Ethernet was configured to enable communication.

  • This paper describes design and implementation experience of SAS-G2S slotmachine accounting protocol middleware system that converts the legacy binary format SAS (Slot Accounting System) protocol with servers with recent standards G2S protocol. The paper examines the difference of two protocols such as link control, message format, and parameters. The converter architecture uses bridge and connector patterns and implemented in C++ and Python mixed language on Linux environment. The prototype system uses a 1GMHz-512MB linux machine and has passed Korean official protocol compatibility and performance test in 2015.

  • Recently, due to the variety and complexity of marine electronics communication devices, much research has been done to adopt the novel communication protocol. Among them, NMEA2000 protocol, is adopted as standardized protocol to the next generation ship. In this paper, we design and implement the conversion algorithm for sensor protocol based on NMEA2000, and analog data module which convert data format between NMEA2000, CAN, Ethernet, RS232. The present study was designed to implement user-based data monitoring system by supporting various communication protocols through the development and application of key technologies through NMEA2000.

  • In this paper, the FPGA-based SoC board (Xilinx Virtex-4 ML401 EVM) is adopted to control electrical power inverter system. For marine application, its performance is shown on PC-based system for monitoring electrical characteristics of a power inverter using by the NMEA 2000 protocol. This power inverter system is achieved in Real-Time monitoring and control by dual micro-processor operation on embedded FPGA-based SoC board. One micro processor is for control (Control processor) electrical power inverter using by PWM signal. And the other microprocessor (Communication processor) is for communication with PC-based monitoring system. The two-processor is communicating each other using by dual-port ram (DPRAM). PC-based system user can control and monitor information of the electrical power inverter via NMEA 2000 based communication processor. Control and monitoring information includes the inverter status and configuration. SoC board converts this information to Parameter Group Numbers (PGNs) in the NMEA 2000 protocol. This system can be applied to marine power electronics for distributed power generation, transmission or regulation systems on the ship.

  • Heterogeneous field sensor network between sensor to sensor is designed the CAN method to bus type structure in most using at industry. This Network is supporting a distance vector routing protocol on a characteristic structural a bus type. Also This network support to convert as making separate routing table in heterogeneous network. However distance vector routing protocol make a problem of decrease efficiency because of restriction of network expandability and low transmission process. We propose new CAN routing protocol to support network expandability and high transmission process of industry network. New CAN routing protocol structure addition priority and optional function field based on RIPv2. We established heterogeneous field sensor network, we measure data Throughput(bits/sec) for confirm new CAN routing protocol to increase efficient in industry.

  • 디지털 AVR은 동기발전기의 출력전압을 부하변동에 관계 없이 일정하게 제어하며 발전기 및 시스템 보호를 위한 각종 제어 알고리즘을 포함하고 있다. 종래의 아날로그 타입 AVR은 제어 설정이 불편하고 제어 신뢰성이 떨어지기 때문에 점차 디지털 타입으로 교체되고 있는 실정이다. 본 논문에서는 디지털 타입의 AVR에 익숙하지 않거나 심화 학습이 필요한 정비 기술자의 교육에 활용할 수 있도록 디지털 AVR 시뮬레이터를 개발하였으며 제어기와 HMI 간의 UDP 통신을 위해 프로토콜 하드웨어 컨버터, HMI, 및 EWS를 개발하였다. 추가로 스마트 단말기에서도 운전 상황을 확인할 수 있는 OIS 앱을 개발하였다.
