Implementation of a Real-Time Data Acquisition System Based on Wireless Communication for Urban Rail Transit Substation

Abstract

Abstract - This paper is focused on implementing a real-time data acquisition system that checks power facility status by applying network based technology to Urban Transit substation power facilities and the results of its on-field tests. This system is composed of a sensor part, a measurement part, a transceiver part, a host computer, and a power source part. The system is designed to collect, save, analyze, and display the online state power facility AI (Analog Input). This system measures voltage and current from positive feeders and negative feeders where it is possible to check abnormalities of the substation’s main power facilities. By monitoring abnormal data of the Urban Transit power facilities real-time and analyzing stored data, establishing procedures of optimized maintenance is possible.Key Words : Real-Time Data Acquisition System, Urban Rail Transit Substation, Wireless Communication ✝ 교신저자, 정회원 : 한국철도기술연구원 전철전력연구실 선임연구원․공박E-mail : hsjung@krri.re.kr * 정 회 원 : 한국철도기술연구원 전철전력연구실 선임연구원․공박
