RAILROAD CAR STABILIZATION MANAGEMENT SYSTEM USING UHF BAND RFID TECHNIQUE

Title:

RAILROAD CAR STABILIZATION MANAGEMENT SYSTEM USING UHF BAND RFID TECHNIQUE

Document Type and Number:

WIPO Patent Application WO/2015/126110

Kind Code:

A1

Abstract:

The present invention relates to: a moving body stabilization management system using an UHF band RFID technique, capable of checking the location and stopping at a correct location and preventing the derailing of a moving body (railroad car) by using an UHF band RFID technique; and an implementation method. To this end, the RFID system, of the present invention, suitable for a railroad environment is described with respect to a car base RFID system, a safe operation zone RFID system and a platform zone RFID system. The main technique of the present invention is largely classified into three types. A first type is an RFID reader technique. The reader technique requires an RF design technique, a signal processing technique and an external interface technique for stable recognition of car speed and for information transmission to a driver. A second type is a tag technique. The main tag technique is a bottom-attached manual tag technique and an active tag technique having high efficiency performance and switching stably operating with respect to a change in a signal of a signaler so as to determine information of the signaler and transmit the information to an RFID reader. A third type is a wireless transmission technique.
