Abstract

Methods and systems to commission building environmental sensors are disclosed. The system include a device that will move about the environment of a building (inside and/or outside) and detect building environmental sensor devices that are installed in the environment. For each of the sensor devices, in response to detecting the sensor device, the system will retrieve an identifier for the sensor device, and it will determine whether the sensor device is registered with a control system. If the sensor device is registered with the control system, the system will not automatically implement a commissioning process with the sensor device. If the sensor device is not registered with the control system, the system will automatically implement the commissioning process with the sensor device.

First claim

The invention claimed is:

1. A system for commissioning building environmental sensors, the system comprising:
a portable electronic device comprising a processor, a receiver, and a non-transitory computer-readable medium containing programming instructions that are configured to cause the processor to, as the portable electronic device moves about an environment:
detect, via the receiver, each of a plurality of building environmental sensor devices that are installed in the environment;
for each of the sensor devices, in response to detecting the sensor device:
determine an identifier for the sensor device,
determine whether the sensor device is registered with a control system,
if the sensor device is registered with the control system, determine whether the sensor device requires re-commissioning,
in response to determining that the sensor device requires recommissioning, implement a commissioning process with the sensor device, and
if the sensor device is not registered with the control system, automatically implement the commissioning process with the sensor device.

2. The system of claim 1 , wherein the instructions to automatically implement the commissioning process comprise instructions to:
determine a location of the sensor device; and
send the location and the identifier to the control system.

3. The system of claim 1 , wherein the instructions to implement the commissioning process further comprise instructions to:
identify a token from the control system that the sensor device can use to communicate with the control system via a wireless network; and
transfer the token to the sensor device.

4. The system of claim 1 , wherein:
the receiver comprises a camera; and
the instructions to detect each of the building environmental sensor devices comprise instructions to:
analyze images captured by the camera to recognize codes in the images, wherein the codes comprise one or more of the following: two-dimensional bar codes, three-dimensional bar codes, or alphanumeric codes, and
upon detection of one of the codes, parse the detected code to extract the identifier for the sensor device from the detected code.

5. The system of claim 1 , wherein:
the receiver comprises a camera; and
the instructions to detect each of the building environmental sensor devices comprise instructions to analyze images captured by the camera to identify an object that is a sensor device in the images.

6. The system of claim 1 , wherein:
the receiver comprises a camera;
the system comprises a wearable augmented reality device comprising a see-through display; and
the instructions to detect the building environmental sensor devices comprise instructions to:
cause the camera to capture the images to correspond to a field of view of the see-through display in real time as the wearable augmented reality device is moved through the environment, and
determine whether any of the sensor devices appear in the field of view of the see-through display in real time.

7. The system of claim 1 , wherein:
the instructions to detect each of the building environmental sensor devices comprise instructions to:
analyze signals received via the receiver, wherein the signals comprise one or more of the following: radio frequency signals, near-field communication signals, or optical signals; and
upon detection of one of the signals, parse the detected signal to extract the identifier for the device from the detected signal.

8. The system of claim 2 , wherein the instructions to determine the location of the sensor device comprise instructions to perform one or more of the following:
receive images from a camera of the system, process the images to recognize a known landmark in the images, access a map of the environment, and determine the location to correspond to a place of the known landmark in the map;
receive images from the camera, output the images on a display of the portable electronic device or of a remote control system, and receive the location via a user interface of the portable electronic device or of the remote control system; or
receive signals from a plurality of beacons in the environment in which the system is moving, and use a triangulation process to process the signals and yield the location.

9. The system of claim 1 , wherein the instructions to implement the commissioning process further comprise instructions to:
detect, via an environmental sensor of the portable electronic device, a first value of an environmental parameter;
query the sensor device for a second value of the environmental parameter as detected by a component of sensing device;
compare the first value and the second value to determine whether the first and second values match; and
in response to determining that the first and second values do not match, determining that the sensor device requires calibration.

10. The system of claim 1 , wherein the system comprises a mobile robotic device.

11. The system of claim 2 , wherein the instructions to determine the location comprise instructions to implement a simultaneous localization and mapping algorithm as the portable electronic device moves about the environment.

12. The system of claim 1 , wherein the instructions to automatically implement the commissioning process with the sensor device further comprise instructions to:
determine one or more configuration parameters for the sensor device; and
transmit the one or more configuration parameters to the sensor device.

13. The system of claim 1 , further comprising instructions to, for each of the sensor devices, in response to detecting the sensor device:
query the sensor device for a battery level report;
analyze a signal received from the sensor device in response to the query; and
when the signal indicates that a battery level of the sensor device is below a threshold, generate an alert.

14. The system of claim 1 , wherein the instructions to determine whether the sensor device requires re-commissioning comprises determining one or more of the following:
determining whether the sensor device was last commissioned more than a threshold period of time ago;
determining whether the sensor device received a software or firmware update since the sensor device was last commissioned;
determining whether the sensor device received maintenance since the sensor device was last commissioned; or
determining whether the sensor device has been moved to a new location.

15. A method of commissioning building environmental sensors, the method comprising:
by an electronic device comprising a processor and a receiver, as the electronic device moves about an environment:
detecting, via the receiver, each of a plurality of building environmental sensor devices that are installed in the environment;
for each of the sensor devices, in response to detecting the sensor device:
retrieve an identifier for the sensor device,
determine whether the sensor device is registered with a control system,
if the sensor device is registered with the control system, determine whether the sensor device requires re-commissioning,
