Abstract
A method and system for graphically displaying real-time system logic used for troubleshooting railroad equipment such as e.g., a grade crossing predictor. The method and system graphically display ladder logic equations used to formulate a system status output, allowing a technician or other personnel to quickly determine the cause of an anomaly reflected in the output.
Claims24
A method of displaying a railroad system status output, the system status output being a signal indicative of a status of a function associated with a gate crossing predictor device, and an underlying logic equation used to formulate the system status output, said method comprising:
- receiving, at a processor within the system, a request for real-time data associated with the gate crossing predictor device and processed by the underlying logic equation to formulate the system status output;
- retrieving, at the processor, the real-time data;
- outputting, from the processor, the real-time data;
- and
- displaying, on a user interface device, a graphic containing the underlying logic equation and comprising a logical association of the real-time data to the system status output,
- wherein the graphic is generated at the user interface device using system configuration information associating the real-time data to the system status output.
A railroad system, said system comprising:
- a gate crossing predictor device comprising a processor programmed to:
- receive a request for real-time data associated with said gate crossing predictor device and processed by a logic equation to formulate a system status output, the system status output being a signal indicative of a status of a function associated with said gate crossing predictor device;
- retrieve the real-time data;
- output the real-time data;
- and
- a user interface device connected to the processor, said device inputting and transmitting to the processor the request for real-time data, said device for receiving the real-time data from the processor and for displaying a graphic containing the underlying logic equation and comprising a logical association of the real-time data to the system status output, the graphic being generated at said user interface device using system configuration information associating the real-time data to the system status output.
