Abstract

A solution for managing effect-generating operations is provided. Data regarding one or multiple types of effects being generated by the operations can be acquired and analyzed. When necessary, actions can be initiated to benefit affected individuals or to improve the operations, e.g., by mitigating a source of excessive effects. In an illustrative application, the effect-generating operations are train operations and the types of effects include acoustic and/or vibration effects.

Claims

1. A system for monitoring operation of a train, the system comprising:

a first set of sensors for acquiring effect data of a first type; and

means for monitoring operation of the train using the effect data acquired by the first set of sensors, wherein the means for monitoring includes;

identifying an acceptable threshold for an area of concern for effects of the first type, wherein the area of concern is a non-rail related location susceptible to being affected by the train operation;

analyzing the effect data of the first type to determine whether the acceptable threshold will be exceeded for the area of concern;

in response to determining the acceptable threshold will be exceeded, initiating an affected user action;

analyzing the effect data of the first type to determine whether a train operation action is required; and

initiating the train operation action in response to determining the train operation action is required.

2. The system of claim 1, wherein the effect data of the first type corresponds to acoustic effects.

3. The system of claim 1, wherein the effect data of the first type corresponds to vibration effects and the first set of sensors includes geophones placed in ballast and oriented to detect motion emanating away from rails used by the train.

4. The system of claim 1, wherein the effect data of the first type corresponds to vibration effects and the first set of sensors includes vibration sensing devices physically attached to at least one rail utilized by the train.

5. The system of claim 1, wherein the identifying includes receiving the acceptable threshold for the area of concern and a time frame for the acceptable threshold from an affected user associated with the area of concern.

6. The system of claim 5, wherein the affected user action includes adjusting a speed of the train.

7. The system of claim 1, wherein the affected user action includes providing information regarding the train operations for use by at least one affected user associated with the area of concern.

8. The system of claim 1, wherein the area of concern is one of:

a research institution or a manufacturing facility.

9. The system of claim 1, wherein the train operation action includes scheduling a rail vehicle on the train for servicing.

10. The system of claim 1, further comprising a second set of sensors for acquiring effect data of a second type, wherein the second type is distinct from the first type, wherein the means for monitoring further includes combining the effect data of the first type and the second type to identify a source of excessive effects of the first type.

11. A system for operating a train, the system comprising:

a first set of sensors for acquiring acoustic effect data based on acoustic effects generated by the train;

a second set of sensors for acquiring vibration effect data based on vibration effects generated by the train; and

means for managing operation of the train using the acoustic and vibration effect data, wherein the means for managing includes;

determining an acceptable threshold for an area of concern for vibration effects, wherein the area of concern is a non-rail related location susceptible to being affected by vibration effects;

analyzing the vibration effect data to determine whether the acceptable threshold will be exceeded for the area of concern;

in response to determining the acceptable threshold will be exceeded, initiating an affected user action;

analyzing the vibration and acoustic effect data to determine whether a train operation action is required; and

initiating the train operation action in response to determining the train operation action is required.

12. The system of claim 11, wherein the first set of sensors includes geophones embedded in a support structure for the rails and ties.

13. The system of claim 12, wherein the first set of sensors further includes vibration sensing devices physically attached to at least one of the rails.

14. The system of claim 11, wherein the affected user action includes adjusting a speed of the train.

15. The system of claim 11, wherein the area of concern is one of:

a research institution or a manufacturing facility.

16. A system for managing vibration-inducing operations, the system comprising:

a set of sensors for acquiring vibration effect data at a plurality of locations relating to the vibration-inducing operations and a first area of concern affected by the vibration-inducing operations; and

means for managing the vibration-inducing operations using the vibration effect data, wherein the means for managing includes;

determining a first acceptable threshold for the first area of concern for vibration effects;

analyzing the vibration effect data to determine whether the first acceptable threshold will be exceeded for the first area of concern;

in response to determining the first acceptable threshold will be exceeded, initiating an affected user action, wherein the affected user action includes at least one of;

adjusting the vibration-inducing operations to avoid exceeding the first acceptable threshold at the first area of concern or informing a first affected user associated with the first area of concern;

analyzing the vibration effect data to determine an operational status of the vibration-inducing operations; and

initiating a vibration-inducing operation action in response to determining the operational status is impaired.

17. The system of claim 16, further comprising a set of sensors for acquiring acoustic effect data at a plurality of locations relating to the vibration-inducing operations and a second area of concern affected by the acoustic effects generated by the vibration-inducing operations, wherein the means for managing further includes:
