Abstract

Embodiments relate generally to systems and methods for optically detecting a flame. A system may comprise an optical flame detector, wherein the optical flame detector comprises a magnetometer, an accelerometer, and a gyroscope; and an information handling system, wherein the information handling system is configured to obtain orientation data from the magnetometer, the accelerometer, and the gyroscope; wherein the orientation data comprises movement and/or vibration data; angular velocity data; and direction data.

First claim

What is claimed is:

1. An information handling system for optically detecting a flame, the information handling system comprising:
an optical flame detector, wherein the optical flame detector comprises a magnetometer, an accelerometer, a gyroscope, a memory device, and a processor,
the memory device configured to store one or more instructions; and
the processor coupled to the memory device, wherein the processor is configured to execute the one or more instructions to:
obtain a first orientation data from the magnetometer, the accelerometer, and the gyroscope, positioned within a housing in the optical flame detector, wherein the first orientation data comprises movement and/or vibration data, angular velocity data, and direction data;
obtain a reference orientation data from at least one of fire detectors, the magnetometer, the accelerometer or the gyroscope, installed on a same platform as the optical flame detector, wherein the fire detectors are different from the optical flame detector, and wherein the reference orientation data comprises movement and/or vibration data, angular velocity data, and direction data;
determine a deviation between the first orientation data and the reference orientation data based at least on a comparison between the reference orientation data and the first orientation data; and
determine whether one or more of the fire detectors or the optical flame detector has moved with respect to periodically monitored reference measurements.

2. The information handling system of claim 1 , wherein the information handling system is connected to the optical flame detector via a wireless connection or a wired connection; and wherein the information handling system is configured to detect an initial installation orientation of the optical flame detector; and to detect a deviation of the obtained first orientation data is within a predetermined limit of the initial installation orientation of the optical flame detector.

3. The information handling system of claim 1 , wherein the optical flame detector comprises at least one of an infrared sensor, a visible light sensor or an ultraviolet light sensor, positioned within the housing, wherein the at least one of the infrared sensor, the visible light sensor or the ultraviolet light sensor are configured to detect flames within a defined distance range.

4. The information handling system of claim 1 , wherein the magnetometer is configured to measure direction relative to an x-axis, a y-axis, a z-axis, or combinations thereof.

5. The information handling system of claim 1 , wherein the accelerometer is configured to measure movement and/or vibration relative to an x-axis, a y-axis, a z-axis, or combinations thereof.

6. The information handling system of claim 1 , wherein the gyroscope is configured to measure angular velocity relative to an x-axis, a y-axis, a z-axis, or combinations thereof.

7. The information handling system of claim 1 , wherein the information handling system is configured to:
recommend, via a user interface, a position of the optical flame detector based on an initial orientation data; and
indicate, via the user interface, whether the recommended position of the optical flame detector is correct or incorrect based on a deviation from the initial orientation data.

8. A method for optically detecting a flame, the method comprising:
positioning an optical flame detector, wherein the optical flame detector comprises a magnetometer, an accelerometer, and a gyroscope;
obtaining, with an information handling system, initial orientation data, corresponding to the optical flame detector, from the magnetometer, the accelerometer, and the gyroscope, wherein the initial orientation data comprises movement and/or vibration data; angular velocity data; and direction data;
obtaining a first orientation data from the optical flame detector, wherein the first orientation data is measured by the magnetometer, the accelerometer, and the gyroscope, positioned within a housing, in the optical flame detector;
obtaining a reference orientation data from fire detectors installed on a same platform as the optical flame detector, wherein the fire detectors are different from the optical flame detector;
determining a deviation between the first orientation data and the reference orientation data based at least on a comparison between the reference orientation data and the first orientation data; and
determining whether one or more of the fire detectors or the optical flame detector has moved with respect to periodically monitored reference measurements.

9. The method of claim 8 , further comprising detecting, with the information handling system, a deviation between the first orientation data from the initial orientation data.

10. The method of claim 9 , further comprising recommending, with the information handling system, a position for the optical flame detector based on the deviation from the initial orientation data.

11. The method of claim 10 , further comprising determining, with the information handling system, whether the deviation is within a predetermined limit.

12. The method of claim 8 , further comprising:
recommending, via a user interface, a position of the optical flame detector based on the initial orientation data; and
indicating, via the user interface, whether the recommended position of the optical flame detector is correct or incorrect based on the deviation from the initial orientation data.
