Study on the TPMS in Rubber-tire LRT

초록

Rubber-tired LRT(light rail transit) has advantages of low noise and vibration over the steel wheel LRT. Therefore, rubber-tired LRT is operated by Busan subway line 4 and Uijeongbu LRT in UTO(unattended train operation). In the case of a rubber-tired LRT, the air pressure drop and a flat tire affect the safe driving. Unattended train operation state is monitored by the control room supervisor. Because it is mostly unmanned system, tire pressure monitoring system is required to prevent the service interruption resulting from flat tire. TPMS(Tire-pressure monitoring system) can be considered as a solution to that problem of tire in rubber-tired LRT. In this study, we have developed a TPMS that can be monitored in real-time status of a tire rubber-tired LRT.
