Abstract
Methods and systems for identifying maintenance tasks in a building. An illustrative method may include capturing a plurality of images over time of a component of a building using an image capture device, comparing at least some of the plurality of images to a baseline image of the component to identify a physical change in the component, determining when the physical change in the component exceeds a threshold physical change, and sending a maintenance request to service the component when the physical change in the component exceeds the threshold physical change.
Claims20
A method for identifying maintenance tasks in a building, comprising:
- capturing a plurality of images over time of a component of a building using an image capture device;
- comparing at least some of the plurality of images to a baseline image of the component to identify a physical change in the component;
- determining when the physical change in the component exceeds a threshold physical change;
- and
- sending a maintenance request to service the component when the physical change in the component exceeds the threshold physical change.
A system for identifying maintenance tasks in a building, comprising:
- an input for receiving a plurality of images from an image capture device that is configured to have a field of view that includes a component of a building;
- an output;
- a memory;
- a controller operatively coupled to the image capture device via the input, the memory and the output, the controller configured to:
- storing a baseline image captured by the image capture device in the memory, the baseline image including an image of the component of the building;
- store a plurality of images from the image capture device to the memory over time, each of the plurality of images including an image of the component of the building;
- compare at least some of the plurality of images to the baseline image of the component to identify a physical change in the component;
- determining when the physical change in the component exceeds a threshold physical change;
- and
- sending via the output a maintenance request to service the component when the physical change in the component exceeds the threshold physical change.
A method for identifying maintenance tasks in a building, comprising:
- sensing one or more environmental conditions in the building;
- capturing a plurality of images over time of a component of a building using an image capture device;
- comparing at least some of the plurality of images to a baseline image of the component to identify a physical change in the component;
- determining when the physical change in the component exceeds a threshold physical change;
- determining that the component might need maintenance when the physical change in the component exceeds the threshold physical change;
- determining when one or more of the sensed environmental conditions in the building also indicate that the component might needs maintenance;
- determining that the component needs maintenance when the physical change in the component exceeds the threshold physical change and the one or more of the sensed environmental conditions in the building indicate that the component might needs maintenance;
- and
- sending a maintenance request to service the component when the need for maintenance is determined.
