Abstract

Systems and methods are disclosed for dynamic addressing of optical fiber sensors in fiber optic interferometry systems. Events that occur along the optical fiber span have defining attributes such as location along the optical fiber span, type, magnitude, time of occurrence, and duration. The event attributes may be used to dynamically form a unique address that fully defines and identifies the event. Other information, such as the corresponding identifier for one or more of the optical fiber span and the corresponding fiber optic interrogator may be included as part of the unique address.

Claims

1. A dynamic addressing scheme for a fiber optic interferometry system, comprising:

a fiber optic interferometer operatively configured as a fiber optic interrogator to detect an event along a fiber optic span, wherein a location of the event detected is determined based, at least in part, on a time delay of arrival of a transmitted signal to a received backscattered signal, wherein the time delay is based on the speed of light in the fiber;

a first processor operative to;

receive the backscattered signal from the fiber optic span,

determine a type of the event,

determine a magnitude of the event,

interrogate the event, wherein interrogation is for at least one of a predetermined time and an event duration,

dynamically create a unique internet address derived from at least one of the type of the event, the magnitude of the event, and a time of the event,

append a message with the unique internet address, and broadcast the message through a network, wherein the network uses the unique internet address to route the message to a predetermined address,

a second processor operative to;

use a predetermined address scheme to receive event messages from the network,

responsive to receiving one of the event messages, use the unique internet address appended to the message to determine at least one of the type of the event, the magnitude of the event, and the time of the event,

responsive to determining the at least one of the type of the event, the magnitude of the event, and the time of the event use a first application to process data contained in the message,

log the data contained in the message to a memory.

2. The system of claim 1, wherein the fiber optic span comprises at least one of a single-mode type, a multimode type, and a polarization preserving type fiber optic cable.

3. The system of claim 1, wherein the fiber optic span is configured to detect at least one type of strain, wherein the type of strain may be acoustic, electromagnetic, mechanical, or thermal.

4. The system of claim 1, wherein the backscattered signal is generated from at least one of acoustic pressure waves, electromagnetic fields, mechanical strain or pressure, and thermal strains or pressures.

5. The system of claim 1, wherein the first processor is at least one of local and remote to the fiber optic interrogator.

6. The system of claim 1, wherein the second processor is located within a remote device.

7. The system of claim 6, wherein the remote device is one of a remote server, a smart phone, a tablet, a laptop, and a personal computer.

8. The system of claim 1, wherein the memory is located within at least one of the first processor, the second processor, and a remote server.

9. The system of claim 1, wherein at least one of the first and second processor is further configured to at least one of characterize and classify the event based on the unique internet address.

10. The system of claim 1, wherein the message is routed in real-time.

11. A method for dynamically addressing events in a fiber optic interferometry system, comprising:

configuring a fiber optic interferometer operatively configured as a fiber optic interrogator to detect an event along a fiber optic span, wherein a location of the event detected is determined based, at least in part, on a time delay of arrival of a transmitted signal to a received backscattered signal, wherein the time delay is based on the speed of light in the fiber;

configuring a first processor to;

receive the backscattered signal from the fiber optic span,

determine a type of the event,

determine a magnitude of the event,

interrogate the event, wherein interrogation is for at least one of a predetermined time and an event duration,

dynamically create a unique internet address derived from at least one of the type of the event, the magnitude of the event, and the time of the event,

responsive to creating the unique internet address, append a message with the unique internet address, and broadcast the message through a network, wherein the network uses the unique internet address to route the message to a predetermined address,

configuring a second processor to;

use a predetermined address scheme to receive event messages from the network,

responsive to receiving one of the event messages use the unique internet address appended to the message to determine at least one of the type of the event, the magnitude of the event, and the time of the event,

responsive to determining the at least one of the type of the event, the magnitude of the event, and the time of the event use a first application to process data contained in the message,

log the data contained in the message to a memory.
