Abstract
An empty-load device feedback arrangement for a train with the railcar having an air brake arrangement with an one air-operable braking assembly, the arrangement including: an empty-load device having: at least one sensor arrangement to sense a load associated with the railcar; a braking assembly input exhibiting a delivered air pressure; a regulation arrangement to regulate air pressure; and a braking assembly output exhibiting a regulated air pressure; and a pressure sensor to: sense the regulated air pressure of the air being delivered to the air-operable braking assembly; and generate a regulated air pressure signal. An air brake arrangement is also disclosed.

An empty-load device feedback arrangement for a train with at least one railcar having an air brake arrangement with at least one air-operable braking assembly, the arrangement comprising:
- (a) at least one empty-load device comprising:
- (i) at least one sensor arrangement configured to sense a load associated with the at least one railcar;
- (ii) at least one braking assembly input exhibiting a delivered air pressure;
- (iii) a regulation arrangement configured to regulate air pressure;
- and
- (iv) at least one braking assembly output exhibiting a regulated air pressure;
- and
- (b) at least one pressure sensor in communication with the regulated air pressure from the at least one braking assembly output, the at least one pressure sensor configured to:
- (i) sense the regulated air pressure of the air being delivered to the at least one air-operable braking assembly;
- and
- (ii) generate a regulated air pressure signal.
In an air brake arrangement comprising:
- at least one air-operable braking assembly for braking at least one wheel of a railcar;
- at least one empty-load device comprising:
- (i) at least one sensor arrangement configured to sense a load associated with at least one railcar;
- (ii) at least one braking assembly input exhibiting a delivered air pressure;
- (iii) a regulation arrangement configured to regulate air pressure;
- and
- (iv) at least one braking assembly output exhibiting a regulated air pressure;
- and at least one local controller configured to control at least one component of the air brake arrangement, an empty-load device feedback arrangement comprising:
- at least one pressure sensor in communication with the regulated air pressure from the at least one braking assembly output, the at least one pressure sensor configured to:
- (i) sense the regulated air pressure of the air being delivered to the at least one air-operable braking assembly;
- and
- (ii) generate a regulated air pressure signal;
- wherein the at least one local controller is further configured to:
- (i) receive the regulated air pressure signal from the at least one pressure sensor;
- and
- (ii) generate downstream air pressure data based at least partially on at least one of the following:
- the regulated air pressure signal, a delivered air pressure signal, an upstream air pressure signal, existing air pressure data, or any combination thereof.
An air brake arrangement comprising:
- at least one air-operable braking assembly for braking at least one wheel of a railcar;
- at least one empty-load device comprising:
- (i) at least one sensor arrangement configured to sense a load associated with at least one railcar;
- (ii) at least one braking assembly input exhibiting a delivered air pressure;
- (iii) a regulation arrangement configured to regulate air pressure;
- and
- (iv) at least one braking assembly output exhibiting a regulated air pressure;
- at least one pressure sensor in communication with the regulated air pressure from the at least one braking assembly output, the at least one pressure sensor configured to:
- (i) sense the regulated air pressure of the air being delivered to the at least one air-operable braking assembly;
- and
- (ii) generate a regulated air pressure signal;
- at least one local controller configured to:
- (i) control at least one component of the air brake arrangement;
- (ii) receive the regulated air pressure signal from the at least one pressure sensor;
- and
- (iii) generate downstream air pressure data based at least partially on at least one of the following:
- the regulated air pressure signal, a delivered air pressure signal, an upstream air pressure signal, existing air pressure data, or any combination thereof.
