Description:
SUPPORT SYSTEM FOR AUTOMATED BUILDING MANAGEMENT ASSISTANCE

FIELD OF THE INV ENTION

[0001] This application relates to the field of building management and, more particularly, to support systems for automated building management assistance.

BACKGROUND

[0002] Building automation systems encompass a wide variety of systems that aid in the monitoring and control of various aspects of building operation for a facility. A building automation system may also control equipment for multiple facilities or subsystems, such as security systems, fire safety systems, lighting systems, and heating, ventilation, and air conditioning (HVAC) systems. Lighting systems and HVAC systems are sometimes referred to as “environmental control systems” to control the environmental conditions within a building or facility.

[0003] The elements of a building automation system may be widely dispersed throughout a facility. For example, an HVAC system may include temperature sensors and ventilation damper controls as well as other elements that are located in virtually every area of a facility or campus. Similarly, a security system may have intrusion detection, motion sensors and alarm actuators dispersed throughout an entire building or campus. Likewise, fire safety systems include smoke alarms and pull stations dispersed throughout the facility or campus. The different areas of a building automation system may have different environmental settings based upon the use and personal likes of people in those areas, such as offices and conference rooms.

[0004] A service organization may send a technician to a building when equipment at the building experiences an issue or needs maintenance. The technician is present at the buildings to maintain or repair the equipment needing attention. For advanced issues, the on-site technician may solicit the assistance of a human staff member at a remote support facility to consult with the technician via a mobile phone. The support staff provides guidance and technical information about the building to assist the on- site technician. Even so, resolution of maintenance or advanced issues may be time- consuming and expensive, particularly when the issues are complex and extensive or when multiple issues need to be addressed.

SUMMARY

[0005] In accordance with one embodiment of the disclosure, there is provided an automated support approach for building automation systems. A facility with a building automation system installed may provide access to an enormous amount of data. Thus, a support system for automated building management assistance may have access to the full state of the facility at any time, which amounts to a large volume of data points. The support system may also be provided access to the historical or trend data for the data points, the alarm and fault detection and diagnostics (FDD) status of various systems and subsystems, the maintenance history of the facility via to the building automation system or other related systems, and access to third party or external data, such as weather or traffic data. The support system may further command the building automation system to actuate controls (such as VAV dampers), change HVAC set points, change schedules, override control strategies, actuate lighting contactors, and other functions of the building automation system and its associated building equipment.

[0006] One aspect is a system for automated building management assistance comprising a mobile device, a building automation system, and a support system. The mobile device is configured to provide a first message identifying a maintenance event for equipment at a particular building and receive a second message identifying completion of the maintenance event for the equipment at the particular building. The building automation system is configured to provide fault detection and diagnostics relating to the maintenance event in response to receiving the first message. The support system is configured to identify a status of the maintenance event as a basic issue or an advanced issue based on the fault detection and diagnostics. The support system also provides manual tasks to the mobile device to address the maintenance event in response to identifying the status as the basic issue and provides semi- automated tasks to the mobile device to address the maintenance event in response to identifying the status as the advanced issue. The manual tasks include manual actions to be executed at the equipment at the particular building based on interactions between the automated support system and the mobile device. The semi-automated tasks include one or more manual actions and one or more automated actions determined by the automated support system for execution by the building automation system.

[0007] Another aspect is a support system for automated building management assistance comprising a first communication component, a second communication component, and a processor. The first communication component is configured to communicate with a mobile device. The first communication component receives a first message identifying a maintenance event for equipment at a particular building and transmits a second message identifying completion of the maintenance event for the equipment at the particular building. The second communication component configured to communicate with a building automation system. The second communication component collects fault detection and diagnostics relating to the maintenance event in response to receiving the first message. The processor is configured to identify a status of the maintenance event as a basic issue or an advanced issue based on the fault detection and diagnostics. The processor also provides manual tasks to the mobile device to address the maintenance event in response to identifying the status as the basic issue and provide semi-automated tasks to the mobile device to address the maintenance event in response to identifying the status as the advanced issue. The manual tasks include manual actions to be executed at the equipment at the particular building based on interactions between the automated support system and the mobile device. The semi-automated tasks include one or more manual actions and one or more automated actions determined by the automated support system for execution by the building automation system.

[0008] Yet another aspect is a method of a support system for automated building management assistance. A first message is received, from a mobile device, identifying a maintenance event for equipment at a particular building. Fault detection and diagnostics relating to the maintenance event is collected from a building automation system in response to receiving the first message. A status of the maintenance event is identified based on the fault detection and diagnostics, in which the status being one of a basic issue or an advanced issue. Manual tasks are provided to the mobile device to address the maintenance event in response to identifying the status as the basic issue. The manual tasks include manual actions to be executed at the equipment at the particular building based on interactions between the automated support system and the mobile device. Semi-automated tasks are provided to the mobile device to address the maintenance event in response to identifying the status as the advanced issue. The semi-automated tasks include one or more manual actions and one or more automated actions determined by the automated support system for execution by the building automation system. A second message is transmitted, to the mobile device, identifying completion of the maintenance event for the equipment at the particular building.

[0009] The above described features and advantages, as well as others, will become more readily apparent to those of ordinary skill in the art by reference to the following detailed description and accompanying drawings.

PET ATT EP DESCRIPTION

[0018] Various technologies that pertain to systems and methods that facilitate support system for automated building management assistance will now be described with reference to the drawings, where like reference numerals represent like elements throughout. The drawings discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged apparatus. It is to be understood that functionality that is described as being carried out by certain system elements may be performed by multiple elements. Similarly, for instance, an element may be configured to perform functionality that is described as being carried out by multiple elements. The numerous innovative teachings of the present application will be described with reference to exemplary non-limiting embodiments.

[0019] The support system for automated building management assistance cooperates with a building automation system to assist human maintenance technician. Expert systems may guide a maintenance technician through maintenance tasks by following decision trees. More importantly, the support system automatically provides guidance about common maintenance tasks and makes automated decisions for addressing technical issues based on real-time access to the state of the building including alarms, historical data about the state of the building including fault detection and diagnostics (FDD) and analytical results and maintenance history, and external data such as weather and traffic information. In addition, the support system may have the capability of commanding the building automation system of the facility to change its state as needed. Examples of such commands include, but are not limited to, changing the state of dampers, valves and lighting contactors; changing the building configuration, such as set points or schedules; and commanding various systems, such as HVACs, to alter their behavior.

[0020] Referring to the FIG. 1, there is shown an example environment 100 that is operable to employ techniques described herein. The environment 100 comprises a facility 102 managed by a building automation system (BAS) 104, which may be co located in part or entirely with the facility. The BAS 104 is configured to provide fault detection and diagnostics relating to maintenance events to remote devices and control the building systems, such as HVAC and lighting, and collects data relating to the performance of the facility 102. Maintenance events include, but are not limited to, maintenance or advanced issues that need to be addressed for proper or optimal operation of the facility 102 and the BAS 104. The environment 100 also comprises an external network or cloud 106, external to the facility 102 and the BAS 104, communicating with the BAS 104 and one or more mobile devices 108. The external network 106 communicating with the BAS 104 collects and stores data relating to the operation of the facility 102 and the BAS 104, identifies trends from the data, and performs analytics on the data, such as FDD. For some embodiments, each mobile device 108 may include a mobile app 110 that may communicate with the external network 106 via a communication component of the mobile device 108.

[0021] The external network 106 comprises an automated support system 112 and a technical support system 114. The automated support system 112 provides automated building management assistance for a maintenance event, and the technical support system 114 is configured to provide manual tasks and/or semi-automated tasks to address the maintenance event. The technical support system 114 may be coupled to, or include, an activity tracking system 116 that queues and tracks tasks and calls assigned to the technical support system 114. The information in the activity tracking system 116 may also be accessed by the automated support system 112 in full or on a limited basis.

[0022] The external network 106 may also comprise a computerized maintenance management system (CMMS) 118 and/or wireless infrastructure 120. The CMMS 118 communicates with the automated support system 112 and manages the scheduling and tracking of maintenance events by assigning a ticket to each event and tracking the status of each event overtime. The wireless infrastructure 120 provides wireless communication capabilities to the external network 106, if not otherwise available via another device of the external network, for communication with one or more mobile devices 108. The wireless infrastructure 120 may provide a communication link between the automated support system 112 and a mobile device 108 and/or the technical support system 114 and the mobile device.

[0023] The interaction and operation of the devices of the environment 110 may be explained by the following example. A technician may receive, or otherwise be aware of, a ticket associated with a maintenance event for repair or maintenance of a building issue of the facility 102. When the technician arrives at the location associated with the maintenance event, the technician begins communications with the automated support system 112 by logging-in to the system via a mobile device 108, such as a laptop, tablet, phone, or other type of wireless communication device. The technician may receive assistance from the automated support system 112 via a mobile device 108, such as a laptop, tablet, phone, or other type of wireless communication device. The automated support system 112 may query the CMMS 118 for open tickets. Where there is more than one possible open ticket associated with the facility 102 or area of the facility, the automated support system 112 may then query the mobile device 108 to determine the appropriate ticket among the multiple possible open tickets.

[0024] During the above operation, the technician may be supported by live human technical support staff, via telephone, such as links between the technical support system 114 and the mobile device 108 through wireless infrastructure 120. The technical support staff also has access to the automated support system 112 via a link within the external network 106 while assisting the on-site technician. For example, when the technician arrives on-site at the facility 102, the technician may use the mobile app 110 of the mobile device 108 to request access to control the automated support system 112 via the mobile app 110. Once that access is granted, the technician may also optionally use the mobile app 110 to request a call from the technical support staff of the technical support system 114. Whether the technician asks for live assistance from a technical support staff or not, the technician may use the mobile app 110 to assist with her or his repair tasks.

[0025] The mobile device 108 may know from the location of the technician which facility 102, or area of the facility, is associated with the maintenance event. For some embodiments, a location determining component of the mobile device 108, such as a sensor for a Global Positioning System (GPS), may determine the location coordinates of the mobile device. The mobile device 108 may also have access to the records of the automated support system 112, or the BAS 104 via the automated support system, the reason dispatching the technician to the site. The automated support system 112 may then proceed to assist the technician with her or his task, using a variety of techniques such as control algorithms and/or machine learning techniques, without requiring the involvement of the technical support staff.

[0026] For example, the automated support system 112 may note that the technician has been dispatched to repair a particular HVAC or lighting system. The mobile device 108 may then proceed to prompt the technician through standard steps to begin repair, such as checking that the system has power, the system is in communication with the automated support system 112, and so on. As needed, the automated support system 112 may also perform other automated tasks to assist the technician. If the system under repair is an HVAC system, the automated support system 112, for example, may run an automated hot/cold test on the HVAC unit and present the results to the technician.

[0027] As the automated support system 112 is assisting the technician, the system may record some or all interactions and data gathered as part of the dispatch to the facility 102. Once technical support staff associated with the technical support system 114 becomes available to assist the on-site technician, the data is available to set the context for the voice or text conversation. After the repair or maintenance task is completed, some or all records are stored at the automated support system 112 to be made available the next time a technician is on-site at the facility 102.

[0028] Referring to FIG. 2, there is shown an example operation of the environment 100. A maintenance event, such as an equipment issue or maintenance task, may be identified 202. The maintenance event may be identified by a person or automated fault detection device at the BAS 104, the automated support system 112 or the CMMS 118. A reference identifier, used for tracking the maintenance event, may be generated 204 in response to identifying the maintenance event. The reference identifier may be generated by a person or automated system at the BAS 104, the automated support system 112 or the CMMS 118. An authentication code may be generated and provided to an on-site technician for interrogation of the maintenance event 206 in response to identifying the maintenance event 202 or generating the reference identifier 204. The authentication code may include a reference to a location and/or an equipment associated with the maintenance event. The authentication code may also include a description relating to the nature of the required on-site visit. For example, the CMMS 118 may receive the authentication code from the automated support system 112 and adds the authentication code to the ticket corresponding to the maintenance event. The CMMS system 118 then schedules a technician to visit the site, supplying some or all of the information identified by the ticket.

[0029] A technician may arrive at the facility associated with the maintenance event as a result of the scheduled visit identified by the ticket of the CMMS system 118. Upon arrival, the technician may use the authentication code provided by the ticket to operate the mobile device 108, 208, such as accessing or logging-in to the mobile app 110. For some embodiments, the mobile device 108 may use a location determining component, such as a sensor for a Global Positioning System (GPS), to confirm that the technician is at the site.

[0030] The mobile device 108 may determine whether there is any meta data 210 available to the mobile device in response to receiving the authentication code. For some embodiments, the mobile device 108 may retrieve meta data from a memory component of the mobile device that relates to the equipment referenced by the authentication code. For some embodiments, the mobile device 108 may retrieve information from a relevant open ticket at the CMMS 118, directly or via the automated support system 112, and provide information about the maintenance event to the mobile device. If meta data is available, then the mobile device 108 may display or otherwise provide information about the maintenance event to an output component of the mobile device 212. For example, the mobile device 108 may display information about the location of the equipment associated with the maintenance event and/or unique identification associated with the equipment. If the meta data is not available, then the mobile device 108 may prompt the technician for a location or other information about the equipment at an input component of the mobile device 214. Examples of prompted information include, but are not limited to, model number, serial number, manufacturer identification, and label names. The mobile device 108 may further store prompted information at the memory component of the mobile device or at a remote database such as one at the automated support system 112 or the CMMS 118. The mobile device 108 may further query about other information, such as a confirmation that the current visit to the site corresponds to the maintenance event. In such case, when the technician confirms, the automated support system 112 may retrieve the other information, such as a document created when the site was commissioned, showing the layout of the equipment, the building layout information, associated wiring, associated panels, and the like, and utilize the mobile device 108 to present (such as display) the other information to the technician. Examples of the building layout information include, but are not limited to, structure, equipment, venting, plumbing, and/or wiring layout associated with the particular building.

[0031] The automated support system 112 may also collect data about the equipment associated with the maintenance event via the BAS 104, such as fault detection and diagnostics data. Examples of the fault detection and diagnostics data include, but are not limited to, a current operating state of at least one unit of the building maintenance system, a current communication states between at least two units of the building maintenance system (for example, whether all units are in communication with the BAS 104), a previous maintenance event of the equipment (for example, when the equipment was last maintained), or a recent maintenance event of the building maintenance system (for example, whether there other support tickets at the CMMS 118 currently outstanding for other equipment and what other faults have been revealed recently).

[0032] The automated support system 112 may consolidate the meta data and any other collected data and determine the approach for troubleshooting the maintenance event 216, 218. After confirming that the technician is ready to begin diagnosing the problem referenced by the authentication code, the automated support system 112 may direct the technician, via the mobile device 108, to perform defined troubleshooting steps 216. For some embodiments, the troubleshooting steps directed by the automated support system 112 may be based on a decision tree corresponding to a type of task associated with the maintenance event. For some embodiments, the automated support system 112 may consolidate the data into a concise report for display by the mobile device 108. Some equipment of the facility 102 may experience basic issues, such as units that perform nominally and require only routine preventative maintenance and units that may perform poorly due to clearly identifiable problems. Other equipment of the facility 102 may experience nominal issues that do not require immediate attention. For example, some equipment may operate comparatively since their last maintenance and may be ignored for the current visit. Still other equipment may experience advanced issues that require further investigation. An example of an advanced issue a unit of an HVAC system that creates cool air but is not able to reduce the temperature within a particular area to a desired set point of the unit.

[0033] For some embodiments, the automated support system 112 may distill the consolidated data into a tree of tasks. For example, for well-performing units, tasks may be sequentially linear and based on a standard HVAC technician handbook, such as changing a filter, cleaning a coil, checking a fan belt, and the like. The mobile device 108, operated by the technician, may acknowledge each task as it is performed or completed, and the acknowledgment may be logged by the automated support system 112 and/or the mobile device 108. For this example, for units that are not performing well, tasks may be tailored based on the problem. For example, if a unit seems ineffective, the automated support system 112 may provide instructions at the mobile device 108 to check the fan, check the coils for possible problems (e.g., an iced condition), check the diffuser for possible blockage, and the like.

[0034] During the course of defined troubleshooting 216, the automated support system 112 may prompt the technician, via the mobile device 108, to perform troubleshooting steps and respond with results observed or received by the technician 218. The troubleshooting steps may include manual actions directly applied to equipment such as controlling a panel or disassembling equipment, and the troubleshooting steps may also include manual actions indirectly applied to equipment such as prompting the technician to capture an image, sound, or multimedia of one or more components of the equipment. Also, during the course of defined troubleshooting 216, the automated support system 112 may command the BAS 104 to run diagnostics and/or test results of attempted troubleshooting steps 220. For example, may command the BAS 104 to order the HVAC to execute a cooling or heating operation and gather information about the supply, zone, duct and outside air temperature. The automated support system 112 may initiate the command automatically in response to a condition or status of the defined troubleshooting 216 or in response to an input by a technician at the mobile device 108. The gathered information may then be presented to the technician and drive the next item in the tree of possibilities. For some embodiments, the automated support system 112 may provide data to the technician, such as displaying information at the mobile device 108, corresponding to the performance of the equipment associated with the maintenance event, in response to and as a result of commanding the BAS 104. The automated support system 112 may further provide historical data associated with the maintenance event, or one or more steps, during the defined troubleshooting 222.

[0035] While directing the technician through tasks, the automated support system 112 may further log each task, gathering associated data from the building and the technician's responses. Also, the automated support system 112 may detect situations indicative of insufficient checking by a technician, i.e., "pencil-whipping" through one or more tasks, based on insufficient time spent on a particular task or group of tasks. In addition, the automated support system 112 may create a record of on-going activities in the activity tracking system 116 of, or associated with, the technical support system 114. As the automated support system 112 records the technician's progress, the automated support system may identify a particular task requiring non- automated assistance. In response to identifying the particular task, the automated support system 112 instructs the technical support system 114 to connect with the mobile device 108 or add the mobile device to its queue. For example, the automated support system 112 may receive the phone number of the mobile device 108 from the mobile device and forward the phone number to the technical support system 114 for a callback. Also, the technical support system 114 may familiarize itself with and/or display information to associated support staff relating to the situation of the technician, including all the work performed, before contacting the technician via the mobile device 108.

[0036] The automated support system 112 may determine whether the equipment issues or maintenance tasks of the maintenance event are resolved or require additional assistance 224 in response to completion of troubleshooting steps and associated actions 216-222. If the issues and tasks are resolved, then a record of the technician's visit is stored at the automated support system 112, the activity tracking system 116, and/or the CMMS 118 (226). The record may include steps performed during the visit as well as the results of the steps. The record may be referenced by the technician, or future technicians, along with any images, sounds, and/or multimedia captured during the visit. For example, after the mobile device 108 communicates to the automated support system 112 that tasks of the maintenance event have been completed, the automated support system make record information associated with the visit, including the resulting performance of the BAS 104. The automated support system 112 may then create automatically an activity in the activity tracking system 116 for the technical support system 114 to review the record and assess the technician's performance. The automated support system 112 may also update the ticket at the CMMS 118 and mark it as complete. If the issues and tasks are not yet resolved, then a record of the technician's progress as provided by the mobile device 108 may be stored at the automated support system 112, the activity tracking system 116, and/or the CMMS 118 (228). In addition, the automated support system 112 may determine that the technician requires assistance, if not previously already determined, and place the technician in a queue for a callback by the technical support system 114 (228).
