Abstract

In this paper we propose a multi-protocol gateway system based on low power wireless communications. The proposed multi-protocol gateway system was designed to allow real-time monitoring and control of the on-site situation through wired and wireless networks by gathering information for streetlight power control and environmental monitoring. The sensing data using multi-sensors with composite processing that selectively used wired or wireless communication (e.g., CDMA, Ethernet (TCP/IP), GPS, etc.) were designed to act as intermediaries that transmitted to the main server through ZigBee. Inaddition, they were designed by separating a CPU board and baseboard to ensure low maintenance cost and ease of hardware replacement. The proposed multi-protocol gateway system’s power, impact, continuous operation stability, and immunity test results obtained a normal operation success rate of over 95% and normal continuous operation results. Moreover, in the voltage drop test , instantaneous immunity test, and conductive RF electromagnetic field immunity test, it obtained an average rating result of “A. 논문 15-40-10-18 The Journal of Korean Institute of Communications and Information Sciences '15-10 Vol.40 No.10 http://dx.doi.org/10.7840/kics.2015.40.10.2006 2006 First Author : Semyung University, School of Computer, megadriver@hanmail.net, 학생회원 ° Corresponding Author : Semyung University, School of Computer, ich410@semyung.ac.kr, 정회원 논문번호:KICS2015-07-230, Received July 19, 2015; Revised September 9, 2015; Accepted September 30, 2015 논문 / 저전력 무선통신 기반 다중 프로토콜 게이트웨이 시스템 설계
