RFID READER DEVICE FOR VEHICLE, RECOGNIZING TAG FOR BOTTOM ATTACHMENT AND TAG INTERWORKING WITH SIGNAL DEVICE IN RAILROAD VEHICLE STABILIZATION MANAGEMENT SYSTEM

摘要

The present invention provides a 900 MHz RFID reader device for a vehicle manufactured as an actual product and an RFID reader device for a vehicle recognizing a tag for bottom attachment (passive tag) and a tag (active tag) interworking with a signal device in a railroad vehicle stabilization management system using a UHF band RFID technique checking the position of a moving unit (railroad vehicle), stopping the moving unit (railroad vehicle) at a predetermined position, and preventing derailment by using a 900 MHz UHF band RFID technique. Also, the present invention provides the tag (passive tag) for bottom attachment interworking with the 900 MHz RFID reader device for a vehicle and the tag (active tag) interworking with the signal device in the railroad vehicle. The RFID system corresponding to railroad environment is divided into a vehicle depot RFID system, a safety driving section RFID system, and a platform section RFID system. An RFID reader technique requires an RF design technique, a signal treatment technique, and an outer interface technique for stable recognition of a vehicle speed and information transmission of a driver. A main tag technique includes the tag (passive tag) technique for the bottom attachment and the tag (active tag) interworking with the signal device having a switch operating to be stable to a signal change of the signal device in accordance with an approach of the railroad vehicle and high efficiency performance to determine information of the railroad signal device and transmitting the information of the railroad signal device to the 900 MHz RFID reader device.;COPYRIGHT KIPO 2017
