Abstract
A brake monitoring system monitors pressures in a brake system of a vehicle system at different locations in the vehicle system. Decreases in the pressures are determined at two or more of the different locations. The times at which the decreases in the pressures occurred are determined. A location of interest of a leak in the brake system is determined by comparing the times at which the decreases in the pressures occurred.
Claims20
A method comprising:
- monitoring pressures in a brake system of a vehicle system at different locations in the vehicle system;
- determining decreases in the pressures that are monitored at two or more of the different locations;
- determining times at which the decreases in the pressures occurred;
- and
- determining a location of interest of a leak in the brake system by comparing the times at which the decreases in the pressures occurred.
2 more elements
A system comprising:
- plural sensor assemblies configured to monitor pressures in a brake system of a vehicle system at different locations in the vehicle system, two or more of the sensor assemblies at the different locations configured to determine decreases in the pressures that are monitored and to determine times at which the decreases in the pressures occurred;
- and
- a system controller configured to determine a location of interest of a leak in the brake system by comparing the times at which the decreases in the pressures occurred.
A system comprising:
- plural sensor assemblies configured to be disposed onboard different non-propulsion-generating vehicles of a multi-vehicle system, the sensor assemblies including pressure sensors configured to measure air pressures in an air brake system of the vehicle system, the sensor assemblies including clock devices and assembly controllers configured to determine decreases in the pressures that are monitored and to determine times at which the decreases in the pressures occurred from the clock devices;
- and
- a system controller configured to receive the times from the sensor assemblies and to determine a location of interest of a leak in the brake system by comparing the times at which the decreases in the pressures occurred.
