US 2014/0270798 A1 · HAZARDOUS LOCATION VISIBLE LIGHT COMMUNICATION NETWORKS

Abstract

A method of communicating a condition in a hazardous location. The method can include determining, using a controller of a first controller communicably coupled to a measuring device, the condition in the hazardous location, and emitting, based on the condition, a first light output from a first light source in the hazardous location. The method can also include receiving, using a second enclosure located in the hazardous location, a visible light communication (VLC) signal from the first light output, and emitting, from a second light source of the second enclosure, a second light output, where the second light output comprises the VLC signal. The method can further include receiving, using a base device, the VLC signal from the second light output, translating the VLC signal into a communication format, and sending the VLC signal in the communication format.

A method of communicating a condition in a hazardous location, the method comprising:

determining, using a controller of a first controller communicably coupled to a measuring device, the condition in the hazardous location;
emitting, based on the condition, a first light output from a first light source in the hazardous location, wherein the first light output comprises a visible light communication (VLC) signal that describes the condition;
receiving, using a second enclosure located in the hazardous location, the VLC signal from the first light output;
emitting, from a second light source of the second enclosure, a second light output, wherein the second light output comprises the VLC signal;
receiving, using a base device, the VLC signal from the second light output;
translating the VLC signal into a communication format;
and
sending the VLC signal in the communication format.

5 more elements

A visible light communication (VLC) network for a hazardous location, the VLC network comprising:

an enclosure comprising a first light source and a first modulation circuit, wherein the enclosure is located in the hazardous location and is communicably coupled to an measuring device, and wherein the first light source emits a first light output that comprises a VLC signal generated by the first modulation circuit;
a second light source comprising a first receiver and a second modulation circuit, wherein the second light source is located in the hazardous location, wherein the first receiver is within a first line of sight of the first light output emitted by the first light source, and wherein the second light source emits a second light output that comprises the VLC signal generated by the second modulation circuit;
and
a base device comprising a second receiver and a translation module, wherein the second receiver is within the second line of sight of a second light output emitted by the second light source, and wherein the translation module translates the VLC signal into a communication format.
