Abstract

The remote control system, in which the remote control server and the actuator are connected and operated through a wireless network, has a great potential risk as well as its convenience. The control commands can be lost because of unreliable wireless channels. The intelligent remote control system is a system that adds a function to infer a control command to the actuator to operate even if the control command is not received. In this paper, we implemented an intelligent remote control system testbed and confirmed the problems that could occur in the remote control system through experiments and verified that the intelligent remote control system solves the problem. The intelligent remote control system can achieve the performance that can be achieved when general remote control system has high communication overhead with less communication overhead.

원격제어서버와 작동기가 무선네트워크를 통해 연결되어 동작하는 원격제어시스템은 그 편의성이 큰 만큼 잠재된 위험성도 크다. 신뢰할 수 없는 무선 채널로 인해 제어명령이 유실될 수 있기 때문이다. 지능형원격제어시스템은 작동기에 제어명령을 유추할 수 있는 기능을 추가하여 제어명령을 수신하지 못하는 경우에도 동작하도록 해주는 시스템이다. 본 논문에서는 지능형원격제어시스템 테스트베드를 구현하여 원격제어시스템에서 발생할 수 있는 문제 상황들을 실험을 통해 확인하고 지능형원격제어시스템이 문제를 해결하는 것을 검증하였다. 지능형원격제어시스템은 일반적인 원격제어시스템이 높은 통신오버헤드를 감수해야 달성할 수 있는 성능을 더 적은 통신오버헤드만으로도 달성할 수 있음을 확인하였다.
