摘要： A process for detecting a derailment of a rail vehicle having two or more rail vehicle parts and one or more articulations through which adjacent rail vehicle parts are rotatably connected with one another includes determining an angle of rotation between adjacent rail vehicle parts, and/or a quantity derived from the angle of rotation. The process further includes comparing the angle of rotation or the derived quantity with at least one reference value or threshold, or with at least one reference value range or threshold range. A test criterion indicating whether or not there is a derailment is defined based on the at least one reference value or threshold, and/or an expected relationship of multiple angles of rotation, and/or an expected relationship of the multiple quantities derived from the angles of rotation, relative to one another. The method further includes determining whether or not the test criterion is met.

摘要： A system that can automatically control the emissions of each locomotive in a consist to reduce overall train emissions. An emissions module determines the amount of emissions emitted by a train. An emissions control module commands the locomotive, via the train control system, to operate in a predetermined state to achieve a particular amount of emissions. A location module can track the location of the locomotive of the train relative geographic locations having emission regulations so that the emissions control module can command appropriate changes in the locomotive to reduce emissions.

摘要： A wireless sensor device includes: an energy harvester configured to convert vibration generated from a broadband vibration source into electricity, an elastic member arranged to receive the vibration and a communication unit fixed by the elastic member, supplied with the converted electricity from the energy harvester, and configured to transmit sensing information obtained by sensing a measurement target. The elastic member operates as a mechanical filter configured to limit a frequency range and an acceleration magnitude of the vibration to be transferred to the communication unit for stabilizing the performance of the communication unit, and the communication unit is arranged to receive vibration passing through the elastic member.

摘要： A system for cooling a power generation system of a locomotive. The power generation system includes an alternator and an engine system. The alternator is coupled to the engine system. The engine system comprises one or more components. The system includes a fan providing air flow, a first sensing module to determine a first temperature of the alternator, a second sensing module to determine a second temperature of the one or more components of the engine system, and a controller. The controller regulates the air flow based on the first temperature and the second temperature.

摘要： According to one embodiment, an abnormality diagnosis apparatus includes processing circuitry. The processing circuitry estimates a reduction amount of a regeneration amount of a diagnosed vehicle that is a railway vehicle, based on vehicle data of the diagnosed vehicle and vehicle data of a peripheral vehicle different from the diagnosed vehicle. The processing circuitry corrects the regeneration amount of the diagnosed vehicle, based on the estimated reduction amount. The processing circuitry diagnoses abnormality of a regenerative brake of the diagnosed vehicle, based on the corrected regeneration amount.
