发明名称 Method and system for position rail trolley using RFID devices
摘要 A method of determining a gauge and a tilt of a rail track at a location includes providing a rail trolley including a processor, a memory coupled to the processor, an RFID reader, a gauge sensor, and a tilt sensor and positioning the rail trolley on the rail track at the location. The method also includes interrogating one or more RFID tags positioned along the rail track and determining, using the processor, a fixed location associated with each of the one or more RFID tags. The method further includes determining, using the processor, the location of the rail trolley in relation to the fixed locations associated with each of the one or more RFID tags and determining the gauge and tilt of the rail track at the location of the rail trolley.

主权项 1. A method of determining a gauge and a tilt of a rail track at a location, the method comprising: providing a rail trolley including a processor, a memory coupled to the processor, an RFID reader, a gauge sensor, and a tilt sensor; positioning the rail trolley on the rail track at the location; interrogating one or more RFID tags positioned along the rail track; determining, using the processor, a fixed location associated the one or more RFID tags based on interrogating the one or more RFID tags; determining a distance between the location and the fixed location associated with the one or more RFID tags, wherein determining the distance between the location and the fixed location associated with the one or more RFID tags comprises using a laser; and determining the gauge and tilt of the rail track at the location of the rail trolley, wherein determining the gauge and tilt of the track includes: determining, using the gauge sensor, a distance between rails of the rail track and;determining, using the tilt sensor, an elevation difference between rails of the rail track.
