RF 모듈 방식의 선박용 냉동 컨테이너 원격 감시시스템 개발

This paper describes a development of ship's refer-container remote monitoring system(RRMS). This system consists of Master, repeater with a switched mode power supply(SMPS) and slave terminal. Slave terminal is composed of wireless MODEM and microprocessor part, checks its conditions like temperature, humidity & etc through the interrogate port(IP) of refer-container, and transmits their data to master. Repeater's role is that connect so that signal which is transmitted from Slave Terminal by Master may not receive electric wave interference by container boxes. We verify the effectiveness of proposed system through the experimental works in container yard and ship.
