Managing multiple devices within a security ecosystem can be a time-consuming and challenging task. This task typically requires an in-depth knowledge of each type of device within the security ecosystem in order to produce a desired workflow when a security event is detected. For example, consider a school system that employs a security ecosystem comprising a radio communication system, a video security system, and a door access control system. Assume that an administrator wishes to implement a first workflow that notifies particular radios if a door breach is detected. Assume that the administrator also wishes to implement a second workflow that also notifies the particular radios when a security camera detects loitering. In order to implement these two workflows, the access control system will have to be configured to provide the notifications to the radios and the video security system will have to be configured to provide the notifications to the radios. Thus, both the access control system and the video security system will need to be configured separately in order to implement the two workflows. As is evident, this requires the administrator to have an in-depth knowledge of both the video security system and the access control system. Thus, the lack of continuity across systems is a burden to administrators since an in-depth knowledge of all systems within the ecosystem will be needed in order to properly configure workflows within the ecosystem.
In order to reduce the burden on administrators and enhance their efficiency, a need exists for a user-friendly interface tool that gives administrators the ability to configure and automate workflows that control their integrated security ecosystem. It would also be beneficial if such a tool equips administrators with the capabilities they need to detect triggers across a number of installed devices/systems and quickly take actions (execute workflows) to reduce the risk of breaches and downtime by automatically alerting the appropriate teams and executing the proper procedures.
The accompanying figures where like reference numerals refer to identical or functionally similar elements throughout the separate views, and which together with the detailed description below are incorporated in and form part of the specification, serve to further illustrate various embodiments and to explain various principles and advantages all in accordance with the present invention.
Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions and/or relative positioning of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of various embodiments of the present invention. Also, common but well-understood elements that are useful or necessary in a commercially feasible embodiment are often not depicted in order to facilitate a less obstructed view of these various embodiments of the present invention. It will further be appreciated that certain actions and/or steps may be described or depicted in a particular order of occurrence while those skilled in the art will understand that such specificity with respect to sequence is not actually required.
In order to address the above-mentioned need, a system, method, and apparatus for implementing workflows across multiple differing systems and devices is provided herein. During operation a workflow is automatically modified, or a new workflow generated, based upon an indication that the workflow was falsely triggered. In particular, a workstation (or server) will receive an indication that the workflow was falsely triggered. The workstation (or server) then determines alternate triggers whose correlated presence or consistent absence can be predicted to reduce the chances that the workflow will again be falsely triggered. The alternate trigger(s) can then be implemented or suggested as a newly-created workflow.
Turning now to the drawings, wherein like numerals designate like components,
Workstation 101 is preferably a computer configured to execute Motorola Solutions' Orchestrate™ and Ally™ dispatch and incident management software. As will be discussed in more detail below, workstation 101 is configured to present a user with a plurality of triggers capable of being detected by systems 130-160 as well as present the user with a plurality of actions capable of being executed by systems 130-160. The user will be able to create workflows and upload these workflows to workflow server 102 based on the presented triggers and actions.
Workflow server 102 is preferably a server running Motorola Solutions' Command Central™ software suite comprising the Orchestrate™ platform. Workflow server 102 is configured to receive workflows created by workstation 101 and implement the workflows. Particularly, the workflows are implemented by analyzing events detected by systems 130-160 and executing appropriate triggers. For example, assume a user creates a workflow on workstation 101 that has a trigger comprising surveillance system 140 detecting a loitering event, and has an action comprising notifying radios within public-safety network 130. When this workflow is uploaded to workflow server 102, workflow server 102 will notify the radios of any loitering event detected by surveillance system 140.
Public-safety network 130 is configured to detect various triggers and report the detected triggers to workflow server 102. Public-safety network 130 is also configured to receive action commands from workflow server 102 and execute the actions. In one embodiment of the present invention, public-safety network 130 comprises includes typical radio-access network (RAN) elements such as base stations, base station controllers (BSCs), routers, switches, and the like, arranged, connected, and programmed to provide wireless service to user equipment, report detected events, and execute actions received from workflow server 102.
Video surveillance system 140 is configured to detect various triggers and report the detected triggers to workflow server 102. Video surveillance system 140 is also configured to receive action commands from workflow server 102 and execute the actions. In one embodiment of the present invention, video surveillance system 140 comprises a plurality of video cameras that may be configured to automatically change their field of views over time. Video surveillance system 140 is configured with a recognition engine/video analysis engine (VAE) that comprises a software engine that analyzes any video captured by the cameras. Using the VAE, the video surveillance system 140 is capable of “watching” video or a live feed to detect any triggers and report the detected triggers to workflow server 102. In a similar manner, video surveillance system 140 is configured to execute action commands received from workflow server 102. In one embodiment of the present invention, video surveillance system 140 comprises an Avigilon™ Control Center (ACC) server having Motorola Solutions' Access Control Management (ACM)™ software suite.
Radio system 150 preferably comprises a private enterprise radio system that is configured to detect various triggers and report the detected triggers to workflow server 102. Radio system 150 is also configured to receive action commands from workflow server 102 and execute the actions. In one embodiment of the present invention, radio system 150 comprises a MOTOTRBO™ communication system having radio devices that operate in the CBRS spectrum and combines broadband data with voice communications.
Finally, access control system 160 comprises an IoT network. IoT system 160 serves to connect every-day devices to the Internet. Devices such as cars, kitchen appliances, medical devices, sensors, doors, windows, HVAC systems, drones, . . . , etc. can all be connected through the IoT. Basically, anything that can be powered can be connected to the internet to control its functionality. Access control system 160 allows objects to be sensed or controlled remotely across existing network infrastructure. For example, access control system 160 may be configured to provide access control to various doors and windows. With this in mind, access control system 160 is configured to detect various triggers (e.g., door opened/closed) and report the detected triggers to workflow server 102. Access control system 160 is also configured to receive action commands from workflow server 102 and execute the action received from workflow server 102. The action commands may take the form of instructions to lock, open, and/or close a door or window.
As is evident, the above security ecosystem 100 allows an administrator using workstation 101 to create rule-based, automated workflows between technologies to enhance efficiency, and improve response times, effectiveness, and overall safety. The above ecosystem 100 has the capabilities to detect triggers across a number of devices within network and systems 130-160 quickly take actions by automatically executing the proper procedure (i.e., executing the appropriate action once a trigger is detected).
IoT devices 163 preferably comprise devices that control objects, doors, windows, sensors, . . . , etc. As is known in the art, a particular communication protocol (IoT protocol) may be used for each IoT device. For example, various proprietary protocols such as DNP, Various IEC**** protocols (IEC 61850 etc. . . . ), bacnet, EtherCat, CANOpen, Modbus/Modbus TCP, EtherNet/IP, PROFIBUS, PROFINET, DeviceNet, . . . , etc. can be used. Also a more generic protocol such as Coap, Mqtt, and RESTfull may also be used.
Gateway 162 preferably comprises an Avigilon™ Control Center running Avigilon's Access Control Management software. Gateway 162 is configured to run the necessary Application Program Interface (API) to provide communications between any IoT device 163 and workflow server 102.
Network 161 preferably comprises one of many networks used to transmit data, such as but not limited to a network employing one of the following protocols: a Long Term Evolution (LTE) protocol, LTE-Advance protocol, or 5G protocol including multimedia broadcast multicast services (MBMS) or single site point-to-multipoint (SC-PTM) protocol over which an open mobile alliance (OMA) push to talk (PTT) over cellular protocol (OMA-PoC), a voice over IP (VoIP) protocol, an LTE Direct or LTE Device to Device protocol, or a PTT over IP (PoIP) protocol, a Wi-Fi protocol perhaps in accordance with an IEEE 802.11 standard (e.g., 802.11a, 802.11b, 802.11g) or a WiMAX protocol perhaps operating in accordance with an IEEE 802.16 standard.
Gateway 151 preferably comprises an Avigilon™ Control Center running Avigilon's Access Control Management software. Gateway 151 is configured to run the necessary Application Program Interface (API) to provide communications between any infrastructure 152 and workflow server 102.
Infrastructure 152 comprises the necessary equipment to provide wireless communications to and from radio 153. Preferably, infrastructure 152 comprises Motorola Solutions MOTOTRBO™ equipment, such as an SLR Series Repeater (e.g., SLR 1000, SLR 5000, or SLR8000 repeater) configured to provide two-way radio service to radio 153.
Although only a single radio 153 is shown in
Cameras 142 may be fixed or mobile, and may have pan/tilt/zoom (PTZ) capabilities to change their field of view. Cameras 142 may also comprise circuitry configured to serve as a video analysis engine (VAE) which comprises a software engine that analyzes analog and/or digital video. The engine is configured to “watch” video and detect pre-selected objects such as license plates, people, faces, automobiles. The software engine may also be configured to detect certain actions of individuals, such as fighting, loitering, crimes being committed, . . . , etc. The VAE may contain any of several object/action detectors. Each object/action detector “watches” the video (which may include a live feed) for a particular type of object or action. Object and action detectors can be mixed and matched depending upon what is trying to be detected. For example, an automobile object detector VAE may be utilized to detect automobiles, while a fire detector VAE may be utilized to detect fires.
Gateway 141 preferably comprises an Avigilon™ Control Center running Avigilon's Access Control Management software. Gateway 141 is configured to run the necessary Application Program Interface (API) to provide communications between any cameras 142 and workflow server 102.
Gateway 133 preferably comprises an Avigilon™ Control Center running Avigilon's Access Control Management software. Gateway 133 is configured to run the necessary Application Program Interface (API) to provide communications between public-safety core network 132 and workflow server 102.
A public safety officer (not shown in
It is envisioned that the public-safety officer will have an array of these shelved devices 112 available to the officer at the beginning of a shift. The officer will select devices 112 off the shelf, and form a personal area network (PAN) with the devices that will accompany the officer on their shift. For example, the officer may pull a gun-draw sensor, a body-worn camera, a wireless microphone, a smart watch, a police radio, smart handcuffs, a man-down sensor, a bio-sensor, . . . , etc. All devices 112 pulled by the officer will be configured to form a PAN by associating (pairing) with each other and communicating wirelessly among the devices. At least one device may be configured with a digital assistant. In a preferred embodiment, the PAN comprises more than two devices, so that many devices may be connected via the PAN simultaneously.
A method called bonding is typically used for recognizing specific devices 112 and thus enabling control over which devices are allowed to connect to each other when forming the PAN. Once bonded, devices then can establish a connection without user intervention. A bond is created through a process called “pairing”. The pairing process is typically triggered by a specific request by the user to create a bond from a user via a user interface on the device. Thus, as shown, public-safety communication system 130 incorporates PANs 136 created as described above. In a preferred embodiment of the present invention, radios 137 and devices 112 form PAN 136, with communication links 138 between devices 112 and radios 137 taking place utilizing a short-range communication system protocol such as a Bluetooth communication system protocol. In this particular embodiment, a pan will be associated with a single officer. Thus,
RAN 135 includes typical RAN elements such as base stations, base station controllers (BSCs), routers, switches, and the like, arranged, connected, and programmed to provide wireless service to user equipment (e.g., radios 137, and the like) in a manner known to those of skill in the relevant art. RAN 135 may implement a direct-mode, conventional, or trunked land mobile radio (LMR) standard or protocol such as European Telecommunications Standards Institute (ETSI) Digital Mobile Radio (DMR), a Project 25 (P25) standard defined by the Association of Public Safety Communications Officials International (APCO), Terrestrial Trunked Radio (TETRA), or other LMR radio protocols or standards. In other embodiments, RAN 135 may implement a Long Term Evolution (LTE), LTE-Advance, or 5G protocol including multimedia broadcast multicast services (MBMS) or single site point-to-multipoint (SC-PTM) over which an open mobile alliance (OMA) push to talk (PTT) over cellular (OMA-PoC), a voice over IP (VoIP), an LTE Direct or LTE Device to Device, or a PTT over IP (PoIP) application may be implemented. In still further embodiments, RAN 135 may implement a Wi-Fi protocol perhaps in accordance with an IEEE 802.11 standard (e.g., 802.11a, 802.11b, 802.11g) or a WiMAX protocol perhaps operating in accordance with an IEEE 802.16 standard.
Public-safety core network 132 may include one or more packet-switched networks and/or one or more circuit-switched networks, and in general provides one or more public-safety agencies with any necessary computing and communication needs, transmitting any necessary public-safety-related data and communications.
For narrowband LMR wireless systems, core network 132 operates in either a conventional or trunked configuration. In either configuration, a plurality of communication devices is partitioned into separate groups (talkgroups) of communication devices. In a conventional narrowband system, each communication device in a group is selected to a particular radio channel (frequency or frequency & time slot) for communications associated with that communication device's group. Thus, each group is served by one channel, and multiple groups may share the same single frequency (in which case, in some embodiments, group IDs may be present in the group data to distinguish between groups using the same shared frequency).
In contrast, a trunked radio system and its communication devices use a pool of traffic channels for virtually an unlimited number of groups of communication devices (e.g., talkgroups). Thus, all groups are served by all channels. The trunked radio system works to take advantage of the probability that not all groups need a traffic channel for communication at the same time.
Group calls may be made between radios 137 and other devices via wireless transmissions in accordance with either a narrowband or a broadband protocol or standard. Group members for group calls may be statically or dynamically defined. That is, in a first example, a user or administrator may indicate to the switching and/or radio network (perhaps at a call controller, PTT server, zone controller, or mobile management entity (MME), base station controller (BSC), mobile switching center (MSC), site controller, Push-to-Talk controller, or other network device) a list of participants of a group at the time of the call or in advance of the call. The group members (e.g., communication devices) could be provisioned in the network by the user or an agent, and then provided some form of group identity or identifier, for example. Then, at a future time, an originating user in a group may cause some signaling to be transmitted indicating that he or she wishes to establish a communication session (e.g., join a group call having a particular talkgroup ID) with each of the pre-designated participants in the defined group. In another example, communication devices may dynamically affiliate with a group (and also disassociate with the group) perhaps based on user input, and the switching and/or radio network may track group membership and route new group calls according to the current group membership.
Radios 137 serves as a PAN main device, and may be any suitable computing and communication device configured to engage in wireless communication with the RAN 135 over the air interface as is known to those in the relevant art. Moreover, one or more radios 137 are further configured to engage in wired and/or wireless communication with one or more local device 112 via the communication link 138. Radios 137 will be configured to determine when to forward information received from PAN devices to, for example, a dispatch center or workflow server 102.
Some examples follow of devices 112 follow:
A sensor-enabled holster 112 may be provided that maintains and/or provides state information regarding a weapon or other item normally disposed within the user's sensor-enabled holster 112. The sensor-enabled holster 112 may detect a change in state (presence to absence) and/or an action (removal) relative to the weapon normally disposed within the sensor-enabled holster 112. The detected change in state and/or action may be reported to portable radio 137 via its short-range transceiver, which may forward the state change to dispatch center 131 or workflow server 102. In some embodiments, the sensor-enabled holster may also detect whether the first responder's hand is resting on the weapon even if it has not yet been removed from the holster and provide such information to portable radio 137.
A biometric sensor 112 (e.g., a biometric wristband) may be provided for tracking an activity of the user or a health status of a user, and may include one or more movement sensors (such as an accelerometer, magnetometer, and/or gyroscope) that may periodically or intermittently provide to the portable radio 137 indications of orientation, direction, steps, acceleration, and/or speed, and indications of health such as one or more of a captured heart rate, a captured breathing rate, and a captured body temperature of the user, perhaps accompanying other information. This information may be reported to radio 137 which may forward the information to dispatch center 131 and/or workflow server 102.
An accelerometer 112 may be provided to measure acceleration. Single and multi-axis models are available to detect magnitude and direction of the acceleration as a vector quantity, and may be used to sense orientation, acceleration, vibration shock, and falling. The accelerometer 112 may determine if an officer is running. A gyroscope is a device for measuring or maintaining orientation, based on the principles of conservation of angular momentum. One type of gyroscope, a microelectromechanical system (MEMS) based gyroscope, uses lithographically constructed versions of one or more of a tuning fork, a vibrating wheel, or resonant solid to measure orientation. Other types of gyroscopes could be used as well. A magnetometer is a device used to measure the strength and/or direction of the magnetic field in the vicinity of the device, and may be used to determine a direction in which a person or device is facing. This information may be reported to radio 137 which may forward the information to dispatch center 131 and/or workflow server 102.
A heart rate sensor 112 may be provided and use electrical contacts with the skin to monitor an electrocardiography (EKG) signal of its wearer, or may use infrared light and imaging device to optically detect a pulse rate of its wearer, among other possibilities. This information may be reported to radio 137 which may forward the information to dispatch center 131 and/or workflow server 102.
A breathing rate sensor 112 may be provided to monitor breathing rate. The breathing rate sensor may include use of a differential capacitive circuits or capacitive transducers to measure chest displacement and thus breathing rates. In other embodiments, a breathing sensor may monitor a periodicity of mouth and/or nose-exhaled air (e.g., using a humidity sensor, temperature sensor, capnometer or spirometer) to detect a respiration rate. Other possibilities exist as well. This information may be reported to radio 137 which may forward the information to dispatch center 131 and/or workflow server 102.
Dispatch center 131 comprises, or is part of, a computer-aided-dispatch center (sometimes referred to as an emergency-call center, Security Operations Center (SOC), or public-safety answering point), that may be manned by an operator providing necessary dispatch operations. For example, dispatch center 131 typically comprises a graphical-user interface that provides the dispatch operator necessary information about public-safety officers. As discussed above, some of this information originates from devices 112 providing information to radios 137, which forwards the information to RAN 135 and ultimately to dispatch center 131.
In a similar manner information about public-safety officers may be provided to workflow server 102. This information originates from devices 112 providing information to radios 137, which forwards the information to RAN 135 and ultimately to workflow server 102 via core network 132 and gateway 133. For example, a gun-draw sensor 112 may send an indication to workflow server 102 that a gun has been drawn. This may serve as a “trigger” for workflow server 102 to initiate a particular “action”, for example, notifying surrounding officers (for example on a particular talkgroup) by having their radios 137 provide an alarm indicating the triggering event. Thus, workflow server 102 may provide instructions to any device 112 or radio 137 by sending an “action” to devices 112 in response to a trigger being received.
Network interface 201 includes elements including processing, modulating, and transceiver elements that are operable in accordance with any one or more standard or proprietary wireless interfaces, wherein some of the functionality of the processing, modulating, and transceiver elements may be performed by means of processor 203 through programmed logic such as software applications or firmware stored on the storage component 202 (e.g., standard random access memory) or through hardware. Examples of network interfaces (wired or wireless) include Ethernet, T1, USB interfaces, IEEE 802.11b, IEEE 802.11g, etc.
Logic circuitry 203 comprises a digital signal processor (DSP), general purpose microprocessor, a programmable logic device, or application specific integrated circuit (ASIC) and is configured to receive triggers from various gateways, systems, and networks. Once a trigger is received, logic circuitry 203 is configured to execute (or cause to be executed) a particular action associated with the trigger. More particularly, when logic circuitry 203 receives a trigger from any attached network or system, logic circuitry will access database 202 to determine an action (if any) for the particular trigger. If an action has been determined that is associated with the trigger, logic circuitry 203 will execute the action, or cause the action to be executed. In order to perform the above, logic circuitry executes an instruction set/software (e.g., Motorola Solutions' Command Central™ software suite comprising the Orchestrate™ platform) stored in database 202.
Database 202 comprises standard memory (such as RAM, ROM, . . . , etc) and serves to store associations between triggers and actions. This is illustrated in Table 1, below.
Network interface 305 includes elements including processing, modulating, and transceiver elements that are operable in accordance with any one or more standard or proprietary wireless interfaces, wherein some of the functionality of the processing, modulating, and transceiver elements may be performed by means of processor 302 through programmed logic such as software applications or firmware stored on the storage component 301 (e.g., standard random access memory) or through hardware. Examples of network interfaces (wired or wireless) include Ethernet, T1, USB interfaces, IEEE 802.11b, IEEE 802.11g, etc.
Logic circuitry 302 comprises a digital signal processor (DSP), general purpose microprocessor, a programmable logic device, or application specific integrated circuit (ASIC) and is configured to execute Motorola Solutions' Orchestrate™ and Ally™ dispatch and incident management software from storage 301. The execution of such software will allow users of GUI 304 to create workflows (i.e., actions and their associated responses) by receiving user inputs from GUI 304 that define various triggers and their associated actions, which will ultimately be uploaded to workflow server 102 and stored in database 202.
Database 301 comprises standard memory (such as RAM, ROM, . . . , etc) and serves to store instructions as software. Particularly, Motorola Solutions' Orchestrate™ and Ally™ dispatch and incident management software is stored in database 301.
GUI 304 provides a man/machine interface for receiving an input from a user and displaying information. For example, GUI 304 provides a way of conveying (e.g., displaying) user-created workflows. Thus, GUI 304 also provides means for a user to input workflows into a displayed form. In order to provide the above features (and additional features), GUI 304 may comprise any combination of monitor 303 (e.g., touch screen, a computer screen, . . . , etc.) and keyboard/mouse combination 306.
Triggers 408 represent the detected events originating from various sensors, software, and devices within security ecosystem 100. Actions 409 represent the possible responses to the triggers. A workflow comprises at least one trigger and at least one action.
After a workflow is deployed (i.e., uploaded to workflow server 102), its actions activate when the triggers occur (are detected). Triggers and actions appear on the workspace after they are dragged and dropped from the triggers 408 and actions 409 areas respectively. Connecting the triggers and actions on the workspace (as described below) will create a workflow.
All triggers 408 and actions 409 are stored in database 301 and represent integrations across multiple products. In other words, triggers and actions comprise triggers and actions for all of the components available in security ecosystem 100. This includes cameras, sensors, IoT devices, radios, . . . , etc. As administrators add additional technology pieces to security ecosystem 100, those pieces are automatically made available for workflow creation as discussed herein.
In order to associate a trigger with an action, a user selects a trigger from all possible triggers 406, and drags and drops it onto workspace area 402. The user then selects an action for the trigger, and drags and drops it onto workspace area 402. In order to associate the trigger with the action, they are connected. To connect the trigger and actions, a user will click the end of one of the node, and drag a line to the other node.
As shown in
As illustrated in
In a similar manner a workflow may comprise multiple triggers associated with a single action. Thus, both the triggers “elevated body tem SAM 12” 604 or “loitering NW staircase” will cause the action of “notify dispatch” 606. Thus, when officer SAM 12 has an elevated body temperature dispatch is notified, and when loitering is detected in the NW staircase, dispatch is notified.
In a similar manner, if one trigger is dragged and dropped onto another trigger, a new trigger is created that defaults to a logical “AND” and comprises both triggers connected with the logical “AND”. For example, if a user places a trigger “door ajar” onto the workspace, and the trigger of “loitering detected” is dragged over the trigger of “door ajar” then a single trigger of “loitering detected AND door ajar” is created. The user can then change the logical AND to a logical OR, AND NOT, WHILE, . . . , etc.
As mentioned above, users can create and implement a workflow by associating a trigger with a particular action, or multiple triggers with an action. Once one of the triggers are detected, the associated action is executed. A workflow being “executed” is considered at least one trigger triggering an action.
When a user (for example, a person constructing a workflow) is trying to create or edit a workflow, the workflow created or edited may lead to many unnecessary false alarms. For example, a user may select a trigger for a workflow as “loitering detected at door A” but is not aware that it is common for workers to gather at door A for coffee during a certain time period. Having the security guard attend to these triggers may be a waste of time and effort for security personnel and potentially overload the security personnel. Another example of the above, consider a trigger of a door vibration sensor used to indicate an attempted intrusion. A single trigger for door vibration would suffice for most instances, however, on a windy day where the door is rattled by the wind, the system would trigger even though it is the wind is making the door vibrate, and not an intruder.
In order to help reduce these workflow “false alarms”, historical data of positive and negative correlation between triggers will be analyzed to determine any pattern that exists when the false alarms happen. (In this case a “false alarm” would be considered the unnecessary execution of a workflow). In order aide in determining patterns of triggers for executed workflows, all workflow executions are monitored, and a table is created of all trigger states within ecosystem 100 during a time period surrounding the time when all workflows are executed (e.g., within five minutes of a workflow being executed). More specifically, a table is created of all triggers within ecosystem 100 and whether or not they have been detected (triggered) within a predetermined time period of a workflow being executed. (An executed workflow comprises at least one trigger of the workflow being detected and an action of the workflow being implemented).
A user can indicate that an executed workflow was a false alarm. When the user indicates that any particular workflow execution was a false alarm, workstation 101 or server 102 will (i) access the table to use the learned historical trigger patterns to identify any relevant trigger pattern for this real-time event; and (ii) suggest to the user a modified workflow that would have correctly suppressed the false alarm. In particular, a workstation (or server) will receive an indication that a workflow was falsely triggered. The workstation (or server) then determines alternate triggers or removal of triggers to reduce the chances that the workflow will again be falsely triggered. The alternate trigger(s) can then be implemented or suggested as a newly-created workflow.
Consider the above example of a workflow named “WORKFLOW 1” comprising a door vibration as a trigger and “alert security” as an action. The creator of the workflow is unaware that the door vibrates when the wind blows above 10 mph. On a windy day, the workflow would be executed even though the wind is making the door vibrate and there is no one attempting to open the door. If a user of workstation 101 identifies the executed workflow as a false alarm, workstation 101 (or server 102) can then determine any correlation between other triggers and the false alarm. As more and more false alarms and true alarms are detected, more sensor data is obtained for the false alarms and the true alarms. Other triggers or trigger patterns (i.e. the addition of, or removal of triggers from the existing workflow) may be suggested that reduce the chances of a false alarm. This is illustrated in
As shown in
As shown in
As shown in
In a similar manner, the system described above can suggest removal of a trigger from a workflow if the removal of the trigger will reduce a number of false alarms by a predetermined percentage over a time period. This is shown in
As shown in
With the above in mind, workstation 101 comprises graphical-user interface 304, database 301, and logic circuitry configured 302. Logic circuitry 302 is configured to monitor executions of an existing workflow, the existing workflow comprising one or more triggers from a plurality of triggers, and an action, the one or more triggers representing a first condition being detected from one or more sensors that cause the execution of the action. Logic circuitry 302 is also configured to receive an input representative of an indication of whether an execution of the workflow was a false alarm, and store data in the database, the data comprising a state of the plurality of triggers during a time period surrounding the executions of the existing workflow, and whether or not each of the executions of the existing workflow was a false alarm. Logic circuitry 302 is also configured to use the stored data to identify a modification to the existing workflow that would have reduced a number of the false alarms if the existing workflow contained the modifications and perform at least one of (i) implement the modification to the existing workflow, (ii) display, on the graphical-user interface the modification to the existing workflow, or (iii) transmit an electronic notification of the modification to the existing workflow to a workflow manager.
The electronic notification may be sent via email, text, or any other electronic means to a person responsible for creating, modifying, or monitoring the workflow. Additionally, the modification to the existing workflow may be implemented by server 102 (or by sending the new workflow to server 102).
As discussed above, the modification to the existing workflow comprises an addition of at least one new trigger to the existing workflow, or a removal of at least one existing trigger to the existing workflow.
Additionally, the modification to the existing workflow can be displayed on the graphical-user interface by displaying the addition of the at least one new trigger to the existing workflow, or displaying a removal of an existing trigger from the workflow.
As discussed, the modification to the existing workflow would have reduced a number of the false alarms by at least a predetermined amount if implemented in the past.
Finally, the input representative of the indication of whether an execution of the workflow was a false alarm is received from a user via the graphical-user interface 304, and in particular, from the keyboard/mouse 306.
In the foregoing specification, specific embodiments have been described. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the invention as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of present teachings.
Those skilled in the art will further recognize that references to specific implementation embodiments such as “circuitry” may equally be accomplished via either on general purpose computing apparatus (e.g., CPU) or specialized processing apparatus (e.g., DSP) executing software instructions stored in non-transitory computer-readable memory. It will also be understood that the terms and expressions used herein have the ordinary technical meaning as is accorded to such terms and expressions by persons skilled in the technical field as set forth above except where different specific meanings have otherwise been set forth herein.
The benefits, advantages, solutions to problems, and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential features or elements of any or all the claims. The invention is defined solely by the appended claims including any amendments made during the pendency of this application and all equivalents of those claims as issued.
Moreover in this document, relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” “has”, “having,” “includes”, “including,” “contains”, “containing” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises, has, includes, contains a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a”, “has . . . a”, “includes . . . a”, “contains . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises, has, includes, contains the element. The terms “a” and “an” are defined as one or more unless explicitly stated otherwise herein. The terms “substantially”, “essentially”, “approximately”, “about” or any other version thereof, are defined as being close to as understood by one of ordinary skill in the art, and in one non-limiting embodiment the term is defined to be within 10%, in another embodiment within 5%, in another embodiment within 1% and in another embodiment within 0.5%. The term “coupled” as used herein is defined as connected, although not necessarily directly and not necessarily mechanically. A device or structure that is “configured” in a certain way is configured in at least that way, but may also be configured in ways that are not listed.
It will be appreciated that some embodiments may be comprised of one or more generic or specialized processors (or “processing devices”) such as microprocessors, digital signal processors, customized processors and field programmable gate arrays (FPGAs) and unique stored program instructions (including both software and firmware) that control the one or more processors to implement, in conjunction with certain non-processor circuits, some, most, or all of the functions of the method and/or apparatus described herein. Alternatively, some or all functions could be implemented by a state machine that has no stored program instructions, or in one or more application specific integrated circuits (ASICs), in which each function or some combinations of certain of the functions are implemented as custom logic. Of course, a combination of the two approaches could be used.
Moreover, an embodiment can be implemented as a computer-readable storage medium having computer readable code stored thereon for programming a computer (e.g., comprising a processor) to perform a method as described and claimed herein. Examples of such computer-readable storage mediums include, but are not limited to, a hard disk, a CD-ROM, an optical storage device, a magnetic storage device, a ROM (Read Only Memory), a PROM (Programmable Read Only Memory), an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory) and a Flash memory. Further, it is expected that one of ordinary skill, notwithstanding possibly significant effort and many design choices motivated by, for example, available time, current technology, and economic considerations, when guided by the concepts and principles disclosed herein will be readily capable of generating such software instructions and programs and ICs with minimal experimentation.
The Abstract of the Disclosure is provided to allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in various embodiments for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separately claimed subject matter.
