Abstract

A device comprises a flame detector, a camera, a mounting device, and a network connection device. The camera has a first field of view that overlaps a second field of view of the flame detector. The mounting device comprises one or more motors to change the first field of view and the second field of view, and the network connection device is configured to provide communication between an output of the flame detector, an output of the camera, and a remote device.

First claim

What is claimed is:

1. An adjustment system for a flame detector, the adjustment system comprising:
a flame detector;
a camera coupled to the flame detector, wherein the flame detector and camera are moveably mounted on a mounting device;
a mobile device, wherein the mobile device comprises a transceiver, a processor, and a memory, wherein an adjustment application is stored in the memory that, when executed upon the processor, configures the processor to:
receive an image of the environment from the camera;
determine a field of view of the flame detector based on an offset of the flame detector from the camera;
display an indicator of the field of view of the flame detector overlaid on the image;
receive an input to adjust the field of view of the flame detector;
generate a movement signal;
send the movement signal to the mounting device, wherein the flame detector and the camera a repositioned relative to the mounting device in response to the movement signal;
receiving a second image from the camera after being repositioned; and
displaying the second image with the indicator of the field of view of the flame detector overlaid on the second image.

2. The device of claim 1 , wherein the camera and the flame detector are disposed in a fixed relationship with respect to each other, and wherein the camera and the flame detector are adjustable relative to the mounting device.

3. The adjustment system of claim 1 , further comprising a second transceiver coupled to the camera, wherein the second transceiver is configured to provide wireless communication between the camera and the mobile device.

4. The adjustment system of claim 1 , further comprising a plurality of motors configured to move the flame detector and the camera relative to the mounting device, wherein the plurality of motors are configured to actuate in response to the movement signal.

5. The adjustment system of claim 1 , where the offset comprises a distance between a center of the flame detector to the center of a lens of the camera, and wherein the adjustment application determines the field of view of the flame detector based the offset, a zoom factor of the camera, and a zoom factor of the flame detector.

6. The adjustment system of claim 1 , wherein the mounting device comprises a second memory, a second processor, and a flame detection application stored in the second memory that, when executed upon the second processor, configures the second processor to receive a signal from the flame detector; determine then a flame is present in the environment; and generate an alarm when a flame is detected in the environment.

7. The adjustment system of claim 6 , wherein the flame detection application further configures the second processor to capture a third image with the camera in response to determining that the flame is present in the environment; and store the third image in the second memory.

8. A method of adjusting the field of view of a flame detector, the method comprising;
receiving, from a camera, an image of an environment;
determining a field of view of a flame detector based on an offset of the flame detector from the camera;
displaying the image of the environment with the field of view of the flame detector overlaid on the image;
receiving an input to adjust the field of view of the flame detector;
sending a movement signal to a mounting device, wherein the field of view of the flame detector is repositioned relative to the mounting device in response to the movement signal; and
displaying the image of the environment with the repositioned field of view of the flame detector overlaid on the image.

9. The method of claim 8 , wherein the camera is arranged in a fixed relationship with respect to the flame detector, and wherein the camera is repositioned with the flame detector.

10. The method of claim 9 , wherein the image of the environment with the repositioned field of view of the flame detector is a repositioned image based on the repositioning of the camera.

11. The method of claim 8 , wherein the image of the environment is received wirelessly from the camera.

12. The method of claim 8 , wherein the movement signal comprises motor movement information, and wherein the flame detector and the camera are repositioned in response to the movement of one or more motors in response to the movement signal.

13. The method of claim 8 , further comprising detecting a heat source in the image of the environment within the field of view of the flame detector, wherein the input to adjust the field of view of the flame detector positions the heat source outside of the field of view of the flame detector.

14. The method of claim 8 , further comprising:
detecting, by the flame detector, a flame in the environment within the field of view of the flame detector;
recording at least one of a still image or a video image with the camera in response to detecting the flame.

15. The method of claim 8 , wherein determining the field of view of the flame detector is based on a distance between a center of the flame detector to the center of a lens of the camera.
