Abstract
The present invention is directed to the use of mobile sensors to collect temperature information used to control, inter alia, rail vehicle speed, acceleration, or scheduling.
Claims37
A system, comprising:
- at least one rail vehicle, the at least one rail vehicle comprising a sensor to measure a temperature of a rail in proximity to the at least one rail vehicle.
A central control system, comprising:
- a server operable to receive, from a plurality of consists at different parts of a rail network, rail temperature measurements and use the rail temperature measurements to determine at least one of speed restrictions, consist routes, current of traffic, traffic mode, consist schedules, timetables, number of trains per hour, consist length restrictions, and consist weight restrictions.
A method, comprising:
- determining, based on sensed data received from at least one mobile sensor, a rail temperature at a selected physical location;
- and
- generating, by a processor, a command to adjust at least one of a velocity, acceleration, and route of a train based on the rail temperature.
A method, comprising:
- receiving, from a plurality of different consists and by a server, a plurality of datasets, each dataset comprising a rail temperature, a timestamp, and a physical location;
- and
- based on the datasets, determining, by the server, at least one of a speed restriction, consist route, current of traffic, traffic mode, consist schedule, timetable, number of trains per hour, consist length restriction, consist type restriction, and consist weight restriction.
