In one embodiment, a multiple-unit rail vehicle system includes a first rail vehicle including a first wireless network device to detect a wireless network. The wireless network is provided by a wayside device. The rail vehicle further comprises a first communication management system to send, through the wireless network, a data communication to a second rail vehicle of the multiple-unit rail vehicle system.
摘要:
Methods and systems are provided for controlling a power transfer rate in to and/or out of a vehicle energy storage device to affect a current state of charge of the energy storage device. The vehicle may be on a mission comprising a plurality of future power transfer opportunities. In one example, the method comprises adjusting the power transfer rate based on an estimated duration of a future power transfer opportunity. Further, the method may include, if the estimated duration of the future power transfer opportunity is different from a predetermined threshold, changing the power transfer rate at the future power transfer opportunity. The method allows the operating life of the energy storage device to be extended.

摘要:
A method for communicating on a train that has at least two locomotives, the method including determining when a primary communication path ceases to be available for a specific subsystem of the train, identifying at least one auxiliary communication path to transmit information for the specific subsystem, configuring a message for the specific subsystem which complies with a message format of the at least one auxiliary communication path, and transmitting the message on the at least one auxiliary communication path. A system and a computer software code are further disclosed for providing a communication system for a powered system.
摘要:
A switched capacitor narrow band pass filter includes a first switch including a first pole movable between two first switch terminals, a second switch including a second pole moveable between second switch terminals, and a third switch including additional poles movable between third switch terminals. The filter further includes an effective capacitor coupled to the first pole and a plurality of matchinq capacitors coupled respectively to the second and third switch terminals. The additional poles are coupled to the third switch terminals according to a first predetermined sequence and to the third switch terminals at a predetermined frequency. A differential amplifier assembly includes two positive and two negative terminals coupled to the additional poles in a second predetermined sequence wherein two of the additional poles are coupled to the positive terminals and two others of the additional poles are coupled to the negative terminals for signal summation.
摘要:
A control system for a refrigeration system having a refrigeration compartment and a quick chill/thaw pan. A main controller board, electrically connected to a temperature adjustment board and a dispenser board through the serial communications bus, controls the temperature of the refrigeration compartment and the quick chill/thaw pan. The control system accepts a plurality of inputs to determine a refrigeration mode and to execute a plurality of software algorithms to control the refrigeration compartment as both a chill pan to rapidly chill food and beverage items without freezing and a thaw pan to timely thaw frozen items at controlled temperature levels.
