Hazardous location visible light communication networks
First Claim
1. A method of communicating a condition in a hazardous location, the method comprising:
- determining, using a controller of a first hazardous location electrical enclosure 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 of the first hazardous location electrical enclosure in the hazardous location, wherein the first light output comprises a visible light communication (VLC) signal that describes the condition, and wherein the first light source emits light outside the first hazardous location electrical enclosure;
receiving, using a receiver of a second hazardous location electrical enclosure located in the hazardous location, the VLC signal from the first light output, wherein the receiver receives the VLC signal in the hazardous location;
emitting, from a second light source of the second hazardous location electrical enclosure, a second light output, wherein the second light output comprises the VLC signal, and wherein the second light source emits light outside the second hazardous location electrical enclosure;
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,wherein the first hazardous location electrical enclosure, including the first light source, is located within and meets the applicable requirements for the hazardous location,wherein the second hazardous location electrical enclosure, including the receiver and the second light source, is located within and meets the applicable requirements for the hazardous location, andwherein the measuring device is located within and meets the applicable requirements for the hazardous location.

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.

10. A visible light communication (VLC) network for a hazardous location, the VLC network comprising:
-
a first hazardous location electrical enclosure comprising a first light source and a first modulation circuit, wherein the first hazardous location electrical enclosure is located in the hazardous location and is communicably coupled to a measuring device, and wherein the first light source emits a first light output that comprises a VLC signal generated by the first modulation circuit, wherein the first light source emits light outside the first hazardous location electrical enclosure, and wherein the measuring device and the first hazardous location electrical enclosure, including the first light source, meet the applicable requirements for the hazardous location; a second hazardous location electrical enclosure comprising a second light source, a first receiver, and a second modulation circuit, wherein the second hazardous location electrical enclosure 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, wherein the first receiver receives the VLC signal in the hazardous location, wherein the second light source emits the second light outside the second hazardous location electrical enclosure, and wherein the second hazardous location electrical enclosure, including the second light source and the first receiver, meet the applicable requirements for the hazardous location; 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
