Abstract

The most industrial instruments for monitoring and control are occurring the extension problem and the external protocol compatibility. In this paper, we developed the boards for the industrial communication monitoring that are able to convert the protocol in various communication between devices and instruments. These are consisted the main board and several sub-board. They can have extension using the main board connection. The sub-board support the each communication method or data transfer. The main board was used the Atmega 2560 Microprocessor of AVR series, and the sub-boards are have the Atmega 256 or Atmega 128 in the AVR series. We have designed to connect the sub-board using placed the 4 RS485 serial slots in the main board. The sub-boards were developed to support the analog and digital I/O. These are able to have monitoring by CAN and Ethernet communication. The experimental results, we obtained good data transfer rate and conversion rate.

모니터링과 제어를 위한 대다수의 산업용 장비들은 항상 확장성 문제와 외부 프로토콜 호환성 문제가 발생하고 있다. 본 논문은 이기종 통신이 발생하는 산업용 통신을 위한 모니터링을 지원하기 위하여 프로토콜 변환이 가능한 보드를 개발하였다. 산업용 통신 모니터링 보드는 메인 보드와 서브 보드로 구성되며, 메인 보드들의 연결로 확장이 가능하다. 메인 보드는 AVR계열의 Atmega 2560을 사용하였고, 서브 보드는 Atmega 256, 128을 사용하였다. 메인보드에는 RS485 시리얼 슬롯 4개를 배치하여 서브 보드를 장착할 수 있게 설계하였다. 서브보드는 아날로그와 디지털 데이터 I/O를 지원하고, CAN과 Ethernet 통신을 이용한 모니터링이 가능하도록 개발하였다.
