Abstract
This invention is related to an economic and practical method of using barcode systems for the management of railroad tracks. The systems consist of barcodes and device(s) which can optically read and decode the barcodes. The barcodes are permanently installed on one or both rails of a railroad track at predetermined locations along the track. The barcodes include coded contents such as track location coordinates and other railroad property information along the track. By using these novel track barcode systems, sections of problematic tracks could be accurately located either manually or automatically for repeatable monitoring, repairing or replacement purposes.
Claims10
A railroad track barcode system comprising:
- (a) a plurality of barcodes, each barcode encoding railroad track location coordinates and railroad property information;
- (b) a plurality of labels carrying said plurality of barcodes on a one-for-one basis, wherein said plurality of labels are attached firmly to a rail of the railroad track at predetermined locations along said railroad track marking said track location coordinates and railroad property information;
- (c) one or more barcode scanners capable of optically reading and decoding said plurality of barcodes, to provide said contents of said plurality of barcodes;
- and
- (d) a vehicle capable of moving on said railroad track, carrying said one or more barcode scanners
- wherein said one or more barcode scanners automatically read and decodes said plurality of barcodes when the vehicle moves by said plurality of barcodes;
- wherein each of said plurality of labels includes a cover, preventing said plurality of labels from exposure to dust and pollutants, wherein said cover includes a hinge mechanism to allow said cover to be flipped over by a device of the vehicle so that said one or more barcode scanners can scan said label.
A railroad track barcode system comprising:
- (a) a plurality of barcodes, wherein each barcodes railroad track location coordinated and railroad property information;
- (b) a plurality of labels carrying said plurality of barcodes on a one-for-one basis, wherein said plurality of labels are attached firmly to a rail of the railroad track at predetermined locations along said railroad track marking said track location coordinates and other railroad property information;
- (c) one or more barcode scanners capable optically reading and decoding said plurality of barcodes, to provide said contents of said plurality of barcodes;
- and
- (d) a vehicle capable of moving on said railroad track, carrying said one or more barcode scanners and directing said one or more barcode scanners at said plurality of barcodes;
- wherein said vehicle includes a gas or liquid nozzle, wherein said gas or liquid nozzle blows gas or injects liquid respectively to said plurality of labels to clean said plurality of labels before said one or more barcode scanners moving by said plurality of barcodes automatically reads and decodes said plurality of barcodes.
A railroad track barcode system comprising:
- (a) a plurality of barcodes, each barcode encoding railroad tracks location coordinates and railroad property information;
- (b) a plurality of labels carrying said plurality of barcodes on a one-for-one basis, wherein said plurality of labels are attached firmly to a rail of the railroad track at predetermined locations along said railroad track marking said track location coordinates and other railroad property information;
- (c) one or more barcode scanners capable of optically reading and decoding said plurality of barcodes optically, to provide said contents of said plurality of barcodes;
- and
- (d) a vehicle capable of moving on said railroad track, carrying said one or more barcode scanners and directing said one or more barcode scanners at said plurality of barcodes;
- wherein said vehicle includes both a liquid nozzle and a gas nozzle, wherein said liquid nozzle and said gas nozzle injects liquid firstly and blows gas secondly to said plurality of labels to wash, clean and dry said plurality of labels before said one or more barcode scanners moving by said plurality of barcodes automatically reads and decodes said plurality of barcodes.
