A building automation server may include a memory that is configured to store a log of geo-fence crossing events including one or more parameters associated with a mobile device. A communications module may be configured to communicate with the mobile device and to receive the one or more parameters associated with the mobile device. A controller may be configured to process the log to diagnose the geo-fencing functionality and, in some cases, to identify one or more corrective actions. In some cases, the controller may be configured to provide the one or more corrective actions to the communications module for output to an external device. In some cases, an external device such as a mobile device may be configured to display messages pertaining to the one or more corrective actions.

Description

TECHNICAL FIELD

The disclosure relates generally to building automation and more particularly to building automation systems with geo-fencing capabilities.

BACKGROUND

Building automation systems are often used to control safety, security and/or comfort levels within a building or other structure. Illustrative but non-limiting examples of building automation systems include Heating, Ventilation and/or Air Conditioning (HVAC) systems, security systems, lighting systems, fire suppression systems and/or the like. In some cases, a building automation system may enter an unoccupied mode when the building is expected to be unoccupied and an occupied mode when the building is expected to be occupied. For example, when the building automation system includes an HVAC system, the building automation system may set a temperature set point of the HVAC system to a more energy efficient setting when in an unoccupied mode and a more comfortable setting when in an occupied mode. In another example, when the building automation system includes a security system, the building automation system may set the security system to a locked or away state when in an unoccupied mode and an unlocked or home state when in an occupied mode. Geo-fencing may be used to inform the building automation system as to whether the building is occupied or not occupied.

SUMMARY

The present disclosure pertains generally to geo-fencing, and more particularly to building automation systems with geo-fencing capabilities. An example of the disclosure may be found in a building automation server that is configured as part of a building automation system for servicing a building. A user of the building may have a mobile device with location services. The mobile device and/or building automation server may store a geo-fence associated with the building and providing a geo-fencing functionality including identifying when the mobile device crosses the geo-fence, resulting in corresponding geo-fence crossing events, and taking corresponding actions. The building automation server may include a memory that is configured to store a log of the geo-fence crossing events. For each geo-fence crossing event, the log may include an indication of the geo-fence crossing event and one or more parameters associated with the mobile device. A communications module may be configured to communicate with the mobile device and receive the one or more parameters associated with the mobile device. A controller may be operably coupled to the memory and the communications module and may be configured to process the log to help diagnose the geo-fencing functionality and, if appropriate, to identify one or more corrective actions. In some cases, the controller may be configured to provide the one or more corrective actions to the communications module for output to an external device. In some cases, the external device may be a mobile device that is configured to display messages pertaining to the one or more corrective actions. In some cases, the external device may be tablet computer, laptop computer, a desktop computer and/or any other suitable external device. In some cases, the messages may be formatted for display in a web browser.

The present disclosure is directed generally at building automation systems. Building automation systems are systems that control one or more operations of a building. Building automation systems can include HVAC systems, security systems, fire suppression systems, energy management systems and/or any other suitable systems. While HVAC systems are used as an example below, it should be recognized that the concepts disclosed herein can be applied to building control systems more generally.

A building automation system may include a controller, computer and/or other processing equipment that is configured to control one or more features, functions, systems or sub-systems of a building. In some cases, devices that can be used by individuals to communicate with the controller, computer and/or other processing equipment. In some cases, a building automation system may include a plurality of components that, in combination, perform or otherwise provide the functionality of the building automation system. A building automation system may be fully contained within a single building, or may include components that are spread between multiple housings and/or across multiple locations. In some embodiments, a building automation system, regardless of the physical location(s) of the components within the building automation system, may control one or more building systems within a single building. In some cases, a building automation system, regardless of the physical location(s) of the components within the building automation system, may control one or more building systems within a plurality of buildings, optionally in accordance with a common operating procedure and/or distinct operating procedures for each building as desired.

FIG. 1 is a schematic view of an illustrative building automation system 10. The illustrative building automation system 10 includes a server 12 that may be configured to communicate with a mobile device 14 and with a building controller 16. It will be appreciated that for simplicity, only a single mobile device 14 is shown, while in many cases the server 12 may be configured to communicate directly or indirectly with any number of mobile devices 14. Similarly, while a single building controller 16 is illustrated, in many cases the server 12 may be configured to communicate directly or indirectly with any number of building controllers 16, located in a single building or distributed throughout a plurality of buildings. The server 12 is illustrated as a single, cloud-based server. In some cases, the server 12 may be a single server. In some instances, the server 12 may generically represent two, three or more servers commonly located or spread between two or more physical locations. In some cases, the server 12 handles communication with both the mobile device 14 and the building controller 16. In some instances, as shown for example in FIG. 2, distinct servers may carry out each communications protocol if desired.

In some cases, the mobile devices 14 may communicate with the server 12 at least partially through a network such as the Internet, sometimes using a cell phone network, WiFi network and/or any other suitable network. Likewise, it is contemplated that the building controller 16 may communicate with the server 12 at least partially through a network such as the Internet, sometimes using a cell phone network, WiFi network and/or any other suitable network.

FIG. 2 is a schematic illustration of another illustrative building automation system 20. The illustrative building automation system 20 includes a first server 22 that may be configured to communicate with a mobile device 14 (or multiple mobile devices 14) and a second server 24 that may be configured to communicate with a building controller 16 (or multiple building controllers 16). The first server 22 may be configured to receive data from the mobile device 14, process the data, and send data to the mobile device 14 and/or to the second server 24. The second server 24 may be configured to receive data from the building controller 16, process the data, and send data to the building controller 16 and/or to the first server 22. In some instances, the first server 22 may be configured to permit data from the mobile device 14 to pass directly through to the building controller 16. In some cases, the second server 24 may be configured to permit data from the building controller 16 to pass directly through to the mobile device 14. The first server 22 and the second server 24 may be configured to communicate with each other. In some cases, each of the first server 22 and the second server 24 may perform a defined function.

It will be appreciated that for simplicity, only a single mobile device 14 is shown, while in many cases the first server 22 may be configured to communicate directly or indirectly with any number of mobile devices 14. Similarly, while a single building controller 16 is illustrated, in many cases the second server 24 may be configured to communicate directly or indirectly with any number of building controllers 16, located in a single building or distributed throughout a plurality of buildings.

The first server 22 is illustrated as a single, cloud-based server. In some cases, the first server 22 may be a single server. In some instances, the first server 22 may generically represent two, three or more servers commonly located or spread between two or more physical locations. The second server 24 is illustrated as a single, cloud-based server. In some cases, the second server 24 may be a single server. In some instances, the second server 24 may generically represent two, three or more servers commonly located or spread between two or more physical locations. In some cases, the first server 22 and the second server 24 may, in combination, be considered as representing or forming a building automation server 26.

FIG. 3 is a schematic illustration of a building automation system 30 in which a building automation server 26 is configured to communicate with a plurality of buildings 32 as well as a plurality of mobile devices 34. It is contemplated that the building automation server 26 may include a single server or two or more distinct servers at one or several locations. The building automation system 30 may serve any desired number of buildings. As illustrated, the plurality of buildings 32 includes a Building One, labeled as 32A, a Building Two, labeled as 32B, and so on through a Building “N”, labeled as 32N. It will be appreciated that the building automation system 30 may include a large number of buildings, each in communication with a central (or distributed) building automation server 26. In some cases, each building may be associated with a unique customer account, as further described below.

As illustrated, each of the plurality of buildings 32 includes a building controller and one or more pieces of building equipment. The building equipment may, for example, be HVAC equipment, security equipment, lighting equipment, fire suppression equipment, and/or the like.

In particular, the building 32A includes a building controller 36A and building equipment 38A, the building 32B includes a building controller 36B and building equipment 38B, and so on through the building 32N, which includes a building controller 36N and building equipment 38N. It will be appreciated that while each building is illustrated as having a single building controller and single building equipment controlled by the single building controller, in some cases a building may have multiple related or unrelated building controllers and/or multiple pieces of related or unrelated building equipment.

The plurality of mobile devices 34 may be considered as being divided into a set of mobile devices each associated with a corresponding building. In the example shown, the plurality of mobile devices 34 may be considered as being divided into a set of mobile devices 40A that are associated with the building 32A, a set of mobile devices 40B that are associated with the building 32B, and so on through a set of mobile devices 40N that are associated with the building 32N. As illustrated, the set of mobile devices 40A includes a first mobile device 42A, a second mobile device 44A and a third mobile device 46A. The set of mobile devices 40B includes a first mobile device 42B, a second mobile device 44B and a third mobile device 46B and so on through the set of mobile devices 40N, which includes a first mobile device 42N, a second mobile device 44N and a third mobile device 46N. This is merely illustrative, as any number of mobile devices such as smartphones or tablets, may be associated with a particular building, as desired. Each user or occupant of a building may have an associated mobile device, or may have several associated mobile devices. In some cases, a user or occupant may have a mobile device associated with several different locations such as a home, a cabin or a place of work.

Associating a mobile device with a particular building generally involves the individual who uses the particular mobile device. In the example shown in FIG. 3, a mobile device can communicate with the building automation server 26, and may cause the building automation server 26 to provide instructions to the building controller that is associated with the particular mobile device. For example, and in some instances, a mobile phone with location services activated can be used to inform the building automation server 26 as to the whereabouts of the user relative to a geo-fence defined for the associated building, and in some cases an estimate of how long before the user will arrive at the associated building. The building automation server 26 may send a command to the building controller of the associated building to operate the building equipment in an energy savings manner when all of the users that are associated with a particular building are determined to be away from the building (e.g. the building is unoccupied). The building automation server 26 may send a command to the building controller of the associated building to operate the building equipment in a comfort mode when all of the users that are associated with a particular building are determined or deemed not to be away from the building (e.g. the building is occupied).

FIG. 4 is a schematic diagram of the illustrative mobile device 14, as previously referenced in FIGS. 1 and 2. The illustrative mobile device 14 has location services 53 for determining a location of the mobile device 14, and includes a user interface 48, a memory 50 and a controller 52 that is operably coupled to the user interface 48 and to the memory 50. In some cases, the memory 50 may be configured to store an executable program and information pertaining to a geo-fence assigned to a building as well as a geo-fence log for storing one or more mobile device parameters and one or more geo-fence crossing events. In some cases, the controller 52 may be configured to determine the location of the mobile device 14 via the location services 53 and to determine when a geo-fence crossing event has occurred. The controller 52 may be configured to record each of the geo-fence crossing events in the geo-fence log, which is stored in the memory 50. In some cases, the controller 52 may be configured to upload the geo-fence log to a remote server, such as the building automation server 26 (FIGS. 2 and 3) from time to time, upon request, or in response to a detected event. In some cases, the controller 52 may be configured to receive geo-fence diagnostic messages pertaining to potential geo-fencing problems ascertained from the geo-fence log from the remote server 26 and to display the geo-fence diagnostic messages on the user interface 48.

In some cases, the controller 52 may record two or more geo-fence crossings in the geo-fence log before uploading the geo-fence log to a remote server. In some instances, the geo-fence log may include a time stamp for each geo-fence crossing event, although this is not required. In some cases, the geo-fence log may also record whether each geo-fence crossing was an inbound geo-fence crossing event, with the user of the mobile device 14 returning towards home, or an outbound geo-fence crossing event, with the user of the mobile device 14 moving away from home, for example.

The geo-fence log may include any variety of information pertaining to the mobile device 14 itself, such as but not limited to a version of the geo-fence application program running on the mobile device 14, the operating system version running on the mobile device 14, the mobile device telecommunications carrier, the brand, model and version of the mobile device hardware itself, a log of geo-fence application program login events, a log of geo-fence application program logout events, a log of geo-fence application program opening events, a log of geo-fence application program closing events, and an indication of whether location services 53 of the mobile device 14 is enabled. Additional illustrative but non-limiting examples include the operating system type, such as iOS or Android; whether background application refreshing is turned on; whether a geo-fence radius or location coordinates have changed, and/or a new device has been added to the customer account. Further examples of information that may be included in a geo-fence log include whether or not background app-refresh is turned on for the geo-fence application program, or the geo-fence coordinates and radii.

In some cases, the user may need to open the geo-fence application program upon initial startup of the mobile device, or after the geo-fence application program has been closed by the user. Once opened, the user may need to log into the user's account via the geo-fence application program to gain access to the user's building automation system. In some cases, the geo-fence application program may be switched to the background by bringing another application program to the foreground. In some operating systems, the application may still be running when in the background (e.g. background app-refresh is on). This user may be able to move the geo-fence application program between the background and foreground, as desired.

In some cases, for each geo-fence event, the geo-fence log may include, for example, geo-fence event time, location ID, the geo-fence trigger type, the radius of the geo-fence and the geo-fence type. The geo-fence log may include any additional data that may be considered as being useful in diagnosing possible errors or problems with the geo-fencing service. It will be appreciated that the particular data collected in the geo-fence log may change over time, and may for example be dictated and/or controlled by the remote server such as the building automation server 26.

In some cases, the geo-fence log may include a number of parameters, including but not limited to the following:

• • ClientApplicationType: identifies iOS or Android.
  • MobileOperatingSystemVersion: operating system version.
  • MobileDeviceCarrier: carrier that mobile device is running on.
  • MobileDeviceToken: unique token generated by environment.
  • AppVersion: version of application.
  • BackgroundAppRefreshEnabled: true if background app refreshing is turned on.
  • LocationServicesEnabled: true if location services is turned on.
  • GeofenceEvents: all geo-fence events sent to cloud since last time this message was sent.
  • LoginLogoutEvents: all login or logout events since last time this message sent.
  • OpenCloseEvents: all open or close events since last time this message was sent.

In some cases, for each LoginLogoutEvent, the following geo-fence parameters are logged:

• • EventTime: time at which event occurs.
  • Type: 0, user logs out; 1, user logs in.

In some embodiments, for each geoFenceEvent, the following geo-fence parameters are logged:

• • EventTime: the time at which the event occurred.
  • LocationID: the location where the geo-fence was crossed.
  • Trigger: a string describing why the geo-fence event was triggered.
  • Radius: the size of the geo-fence radius. Type: 0 means user has entered the geo-fence, 1 means user has left the geo-fence.

Each of these may be considered as examples for the Trigger field of each GeoFenceEvent:

• • FenceCrossed: a normal geo-fence event following a fence crossing.
  • OpenedFromPoweredOff: geo-fencing application was opened after the phone was off.
  • OpenedFromForcedClose: geo-fencing application was opened after the application was forced-closed.
  • NewShortcut: a new geo-fence shortcut was created, such as on the geo-fencing application.
  • ModifiedShortcut: a geo-fence shortcut was modified, such as on the geo-fencing application.
  • ObservedShortcutChange: geo-fencing application loaded shortcut changes which may have been created by another user on another geo-fencing application.
  • GeofenceModified: geo-fencing application modified geo-fence coordinates or radius.
  • ObservedGeofenceModified: geo-fence application loaded a geo-fence change which may have been caused by another user on another geo-fencing application, for example.
  • NewLocation: geo-fencing application added a new location.
  • ObservedNewLocation: geo-fencing application loaded a new location.
  • LoggedIn: user logged in.It will be appreciated that these examples are illustrative only.

In some embodiments, the controller 52 of the mobile device 14 may upload the geo-fence log to a remote server, such as the building automation server 26, in accordance with a particular time frame. For example, the geo-fence log may be uploaded if a predetermined period of time has expired since the last upload. In some cases, the predetermined period of time may be a period that is less than 24 hours, 12 hours, 6 hours or less. In some cases, the predetermined period of time may not be a set length of time, but may instead be determined by the length of time for a particular number of geo-fence crossings to occur. For example, the controller 52 may upload the geo-fence log after every two geo-fence crossings, after every three geo-fence crossings, or any number of other geo-fence crossings. In some cases, the controller 52 may upload the geo-fence log in response to a trigger, which may include something done at or on the mobile device 14, and/or a remote event that is communicated to the mobile device 14.

In one example, a trigger may be the detection of a user logging into the geo-fence application program on the mobile device 14 via a physical login, in which the user enters their username and password, or an auto-login in which the application remembers and fills in the user's username and password. Another example trigger may be the detection of a user logging into the geo-fence application program after a forced close of the geo-fence application program, or the detection of a user logging out of the geo-fence application program. In some cases, a geo-fence crossing may function as a trigger. In some instances, the mobile device 14 may receive a request from a remote server, such as the building automation server 26, to upload the geo-fence log. This may be considered an external trigger.

FIG. 5 is a schematic view of an illustrative building automation server 26, as previously referenced in FIGS. 2 and 3. The building automation server 26 may be configured for servicing a user's building and, in some cases, other buildings as well. The building automation server 26 may include a memory 54, a communications module 56 and a controller 58 that is operably coupled to the memory 54 and to the communications module 56. The memory 54 may be configured for storing a geo-fence that defines a region about the user's building, as well as a log describing mobile device conditions and/or executable program conditions that correspond to geo-fence cross events. The memory may be RAM memory, optical storage, hard disk storage, and/or any other suitable memory.

In some cases, the communications module 56 is configured to communicate with an HVAC controller controlling an HVAC system within the user's building, and the HVAC controller controls the HVAC system at least in part in accordance with information corresponding to geo-fence crossing events. In some cases, an indication of the geo-fence crossing event includes a geo-fence crossing type of inbound or outbound. Sometimes, an indication of the geo-fence crossing event includes a timestamp.

In some cases, the geo-fence log stored in the memory 54 provides a geo-fencing functionality that includes, for example, identifying when the mobile device 14 crosses the geo-fence. The memory 54 may be configured to store a log that includes, for each geo-fence crossing event, an indication of the geo-fence crossing event and one or more parameters that may be associated with the mobile device 14. The memory 54 may be considered as storing the geo-fence log(s) uploaded from one or more mobile devices 14 via the communications module 56. The communications module 56 may be configured to communicate with the user's mobile device 14 and receive the information including the geo fence log describing mobile device conditions and/or executable program conditions that correspond to geo-fence crossing events. The communications module 56 may, for example, be configured to communicate with the mobile device 14 and receive one or more parameters that are associated with the mobile device 14.

In some cases, the one or more parameters that are associated with the mobile device 14 may include one or more of a mobile device type, the brand, model and version of the mobile device hardware itself, a mobile operating system version, one or more programmable operating system settings, a mobile device carrier, an indication of whether the location services of the mobile device 14 is enabled, a current location of the mobile device 14 reported by the location services of the mobile device 14, a connection status of the mobile device 14 to a network, a signal strength indicator, a battery status indicator, a memory usage indicator, a processor usage indicator, and a timestamp.

In some cases, the executable program may be a geo-fence application program running on the mobile device 14 in order to facilitate geo-fencing functionality. In some cases, the one or more parameters that are associated with the mobile device 14 include one or more of a version of the application program, one or more programmable settings of the application program, and one or more errors recorded by the application program. In some cases, the geo-fencing log stored by the memory 54 includes one or more of login events associated with logging into the application program, logout events associated with logging out of the application program, application opening events associated with opening the application program, closing events associated with force closing the application program, foreground events associated with bringing the application program to the foreground, and background events associated with bringing the application program to the background.

In some cases, the log may also include, for each geo-fence cross event, one or more parameters associated with the building automation server 26 itself. For example, the one or more parameters associated with the building automation server 26 may include one or more of a building automation server type, a building automation server operating system version, a connection status of the building automation server 26 with a network, a memory usage indicator, a processor usage indicator, one or more errors recorded by the building automation server 26, a timestamp, a user account associated with the external device, and a number of external devices currently associated with the user account.

In some cases, the controller 58 may be configured to communicate with a building controller located within the building (such as one or more of the building controller 36a, 36b through 36n as shown in FIG. 3), and for each geo-fence crossing event, the log may further include one or more parameters associated with the building controller. For example, the one or more parameters associated with the building controller may include one or more of a building controller type, a building controller operating system version, a building controller application program version, one or more programmable settings of the building controller, a connection status of the a building controller to a network, a signal strength indicator, a battery status indicator, a memory usage indicator, a processor usage indicator, a timestamp, a current state of equipment controlled by the building controller, and one or more sensor readings of the building controller.

In some cases, the mobile device 14 may be configured to store the geo-fence associated with the building and to identify when the mobile device 14 crosses the geo-fence and the communications module 56 may be configured to receive the indications of the geo-fence crossing events from the mobile device 14 and store them in the memory 54. In some cases, the memory 54 may be configured to store a plurality of logs each associated with a corresponding mobile device 14 and the controller 58 may be configured to process the plurality of logs to identify the one or more corrective actions. In some cases, at least two of the plurality of logs relate to different buildings and/or different user accounts.

In some embodiments, the controller 58 may be configured to process the information including the log describing mobile device conditions and executable program conditions that correspond to geo-fence crossing events and to output, via the communications module, diagnostic data pertaining to the processed information. The diagnostic data may be useful in diagnosing geo-fence problems and may help improve geo-fence reliability, accuracy and performance. In some cases, the controller 58 may be configured to identify one or more corrective actions that may be carried out to correct a potential geo-fencing problem.

In some cases, depending on the possible corrective actions determined, emails may be sent out to users of particular applications. For example, certain issues may affect iPhones® (running iOS) but not impact Android™ users while other issues may affect Android users but not impact iOS users. In some cases, it may be determined, for example, that a user has more than one phone set up for geo-fencing on a single account, and they may proactively be notified (e.g. by email, SMS message, etc.) suggesting that this be corrected (e.g. by creating a user account for each phone). If a user does not have geo-fencing set up correctly, such as if they have the wrong number of shortcuts set up, they may be proactively contacted. The system may analyze data in order to measure system performance at different parts of the system. Data may be analyzed to determine how many users have correctly setup geo-fencing and perhaps to look for trends in situations where geo-fencing is not set up correctly. If particular features are especially problematic, the system may determine future development and/or enhancements to the geo-fencing functionality.

In some cases, diagnosing the geo-fencing functionality includes determining if one or more settings of the mobile device 14 are setup correctly. If a determination is made that there is an incorrect setting on the mobile device, the building automation server 26 may send the mobile device 14, via the communications module 56, a message such as a text message, an email or other image or icon suggesting to a user of the mobile device 14 that they manually change the incorrect setting on the mobile device 14 to a correct setting. In some cases, the building automation server 26 may send a communication to the mobile device 14 via the communications module 56 that causes the mobile device 14 and/or the geo-fence application running on the mobile device 14 to automatically correct the incorrect setting on the mobile device 14. In some instances, diagnosing the geo-fencing functionality may, for example, include determining if the building automation server 26 is operating correctly.

In some cases, the controller 58 may be configured to process information contained within the log and to output at least some of the processed information via the communications module 56. In some cases, the controller 58 may be configured to output the processed information in graphical or tabular form for display on a display. FIGS. 6-9 provide illustrative but non-limiting examples of the how processed log information may be displayed. In some cases, the processed log information may be displayed on a computer monitor operably coupled to the building automation server 26, for example, or printed on a similarly connected printer.

FIG. 6 graphically represents, over time, a percentage of communication failures between individual mobile devices (such as smartphones) and a building automation server identified by the nickname Server1. If the communication failures are particularly high at the same time geo-fence errors are detected and logged by the mobile devices, the source of the geo-fence errors may be attributed to the communication failures. FIG. 7 provides some statistical information in tabular form, including total number of users serviced by the building automation server during a two week time period, the number of different locations, the percent of registered thermostats that were offline, the percent of locations with improper geo-fence shortcuts, the percent of locations with the HVAC controller in the hold mode (and thus Geo-fencing is inactive), the percent of users that have multiple geo-fence phones assigned to the same user (which in some cases is not allowed), the percent of errors for communications between iOS phones and the building automation server, and the percent of errors for communications between Android phones and the building automation server. As can be seen, in this example, the displayed data are derived from logs obtained from many mobile devices across many user accounts, and can help identify and/or diagnose sources of geo-fence problems on a global basis. In some cases, the information that is displayed may be tailored to a specific mobile device and/or specific user account, as desired.

A shortcut may be programmed into the thermostat that enables a user to quickly and easily, by selecting a single button on the thermostat or their smartphone, instruct the thermostat to carry out one or more instructions.
