Abstract
A robust system processor comprising three parallel processors, each configured to process in parallel an input and emit an output; and a reconciler that compares the three outputs, determines whether at least two of the outputs are equal, and if so validates the majority output and communicates the validated output via a network to at least one other system processor.
Claims15
A train control system comprising a robust system processor, the train control system comprising:
- a train set including at least one railway car;
- a track switch controller;
- at least one first set of two track points located along a first track switch section;
- at least one second set of two track points located along a second track switch section coupled via a track section to the first track switch section;
- at least one RFID tag having no preprogrammed data and which is located at each of at least the one first set of two track points configured to store dynamic and static characteristics of a train set as it passes the at least one first set of two track points, wherein the dynamic characteristics stored on the at least one RFID tag are configured to be updated at the at least one first set of two track points, according to characteristics of the train set passing by the at least one first set of two track points;
- the at least one second RFID tag having no preprogrammed data and which is located at each of the at least one first set of two track points and the at least one second set of two track points, the at least one RFID tag being configured to store dynamic and static characteristics of the train set as it passes the at least one second set of the at least two track switches;
- at least one RFID tag reader located on at least one railway car connected to a network, wherein the at least one railway car writes data to the at least one RFID tag such that the data is read by the at least one RFID tag reader of a following railway car, and wherein the data of the at least one RFID tag is overwritten with new data each time at least one railway car passes by the at least one first set of two track points and as it passes by the at least one second set of the two track points;
- and
- the robust system processor comprising:
- three parallel processors each configured to process in parallel an input and emit an output, wherein each of the three parallel processors includes a reconciler that is configured to:
- compare outputs of the three parallel processors;
- determine whether at least two of the outputs of the three parallel processors are equal;
- in response to a determination that the at least two of the outputs are equal,
- validate the at least two of the outputs;
- and
- communicate the at least two of the outputs as a majority output via a network to at least one second system processor;
- and
- in response to a determination that the at least two of the outputs are not equal, adjust a non-majority output of the outputs to the majority output.
