Abstract
A system and method for automatic generation of a list of units in a train comprising multiple units use a plurality of sensors, wherein each of the plurality of sensors is configured to be mounted to a respective unit of the train and each of the plurality of sensors is configured to detect a parameter of the respective unit of the train to which it is mounted that is suitable to provide an information about the position of the unit with respect to another unit in the train. Further, the system includes a control device configured to receive the detected parameters from the plurality of sensors and to process the detected parameters for generation of the list of units.
Claims13
A system for automatic generation of a list of units in a train comprising multiple units, the system comprising:
- a plurality of sensor means, wherein each of the plurality of sensor means is configured to be mounted to a respective unit of the multiple units of the train and each of the plurality of sensor means is configured to detect a parameter and a pressure, of the respective unit of the train to which it is mounted and configured to provide an information about a position of the respective unit with respect to another unit of the multiple units in the train, and wherein each of the plurality of sensor means is configured to communicate with one or more of the plurality of sensor means, and the plurality of sensor means forms a sensor mesh network to transmit the detected parameters for processing;
- and
- a control device configured to receive the detected parameters from the sensor mesh network, to process the detected parameters, and to generate the list of units,
- wherein each of the plurality of sensor means and the control device comprises a wireless communication module to send and receive signals, and each of the plurality of sensor means is configured to detect a signal strength and identifier of the at least one neighboring sensor means from which the information about the position of the unit in the train to which the sensor means is mounted is derived,
- wherein each of the plurality of sensor means is configured to use the wireless communication module for a wireless unit-to-unit communication, and wherein the wireless communication modules of the plurality of sensor means wirelessly transmit each of the detected parameters, identifiers, pressures, and signal strengths,
- wherein the control device is configured to generate the list of units based on each of the identifiers and any of the detected parameters, pressures, and signal strengths in response to unavailability of a global navigation satellite system module.
A method for automatic generation of a list of units in a train comprising multiple units, the method comprising:
- associating each of a plurality of sensor means to a respective unit of the train
- each of the plurality of sensor means being configured to communicate with one or more of the plurality of sensor means, and the plurality of sensor means forming a sensor mesh network;
- each of the plurality of sensor means detecting a parameter and a pressure of the respective unit, to provide an information about a position of the respective unit in the train
- each of the plurality of sensor means transmitting the detected parameters via the sensor mesh network to a control device or a server;
- and
- receiving the detected parameters from the sensor mesh network at the control device and processing the detected parameters to generate the list of units;
- associating each of the plurality of sensor means with an identifier of the unit in the train the sensor means is associated with and each of the plurality of sensor means transmitting the identifier of the unit in the train to the control device for processing and generation of the list of units;
- detecting, with one or more of the plurality of sensor means, a signal strength of at least one neighboring sensor means to provide the information about the position of the unit associated with the neighboring sensor means in the train, wherein each of the plurality of sensor means and the control device comprise a wireless communication module to send and receive signals, and transmit the information about the position of the unit associated with the neighboring sensor means in the train, and wherein each of the plurality of sensor means uses the wireless communication module for a wireless unit-to-unit communication, and wherein the plurality of sensor means forms a wireless sensor mesh network;
- wirelessly transmitting each of the detected parameters, identifiers, pressures, and signal strengths, strengths;
- and
- generating the list of units based on each identifier of the identifiers and any of the detected parameters pressures, and signal strengths in response to unavailability of a global navigation satellite system module.
