Efficient data acquisition for track databases |
摘要 |
An improved method of rail survey deploys feature identification tags along an inner edge of a train track rail. Each tag includes a unique identifier to identify a respective feature along the train track. Each tag includes a reflector to reflect light to a sensor on a track surveyor. The sensor reads track feature tags without the need for stopping at each feature. A track database is provided that is capable of storing tables that associate track features with geo-locations. As each tag is deployed or read during a rail survey, it can be paired with geo-location data and stored in the track database. |
