Patent Images
1. A method of detecting and signaling a hot box condition on a rail vehicle comprising the steps of:
- acquiring temperature data from undercarriage components of the rail vehicle through temperature sensors provided in hot box detection devices arranged in a sequence leading to a data recorder; and
relaying the temperature data through a wireless network of the hot box detection devices to the data recorder by sequentially transmitting the temperature data from one of the hot box detection devices in the sequence through each of the remaining hot box detection devices in the sequence that are nearer to the data recorder.
