Description
FIELD OF THE INVENTION

The disclosure relates to the field of electronic lock systems. In particular, the disclosure relates to an electronic locking method and system for providing an automatic real-time notification to at least one user using one or more communication mediums.


BACKGROUND

In electronic lock systems where an electronic lock is securing a storage space, once a tenant accesses the electronic lock, it is desirable to ensure that the tenant leaves the space secured with a door closed and the latch bolt of the electronic lock physically re-locked.


The electronic lock may not be physically locked unless and until the tenant moves the latch trigger from left to right to engage the latch bolt with the door frame. The challenge is sometimes when the tenant may forget to move the latch trigger from left to right. Also, the tenant may leave the storage area (for e.g., 5 miles away, etc.), and thereafter the tenant may realize that the electronic lock is not physically locked. It may cause a security risk to the storage space.

FIG. 1 illustrates an example block diagram of electronic locking system 100 for providing automatic real-time notification to at least one user ensuring the security of the storage space, according to one or more embodiments of the disclosure.


The electronic locking system 100 is only one example of the electronic locking system and is not intended to suggest any limitation as to the scope of use or operability of embodiments of the invention described herein (indeed additional or alternative components and/or implementations may be used).


The electronic locking system 100 includes an electronic lock 101 including a latch 101A and a latch status indicator 101B, a user mobile device 105 associated with a user 103 shown at multiple different positions within the electronic locking system 100, a communication gateway 107, a geo-fence environment represented by a geo-fence 109, an environment 111 outside the geo-fence 109, an administrator 113, and a cloud device 115. As a non-limiting example, the environment 111 may include an elevator area 111A, a parking area 111B, or any other area outside the geofence 109.


The electronic locking system 100 may also include a computing device including at least one processor and/or controller that may perform communication between the user device 105 and the electronic lock 101 and the communication gateway 107. The at least one processor may monitor other components and subcomponents of the electronic locking system 100 or communicate with other components and subcomponents of the electronic locking system 100 through any network communication technologies that can monitor the geofence environment and environment outside the geofence 109. Examples of other systems and subsystems may include security systems, home automation systems, car service systems, travel indication systems, etc. Examples of automatic real-time notifications and/or signals may include generating emails, generating text messages, providing a report to the user, providing real-time status of the latch 101A of the electronic lock 101, etc.


The user device 105 may be an electronic device having short and/or long range communication and location services. As a non-limiting example, the user device 105 may be a smartphone with short and/or long range communication and location services enabled. The user device 105 may also communicate with other systems and sub-systems through any network communication technologies that can monitor the geo-fence environment and may provide automatic notifications to the user 103 (E.g., tenant, etc.). The user device 105 may include a sensing unit to capture the user movements within an environment and a notification application stored on a memory of the user device that provides computer readable instructions to monitor the geo-fence 109 and acquire data parameters therefor. The sensing unit may include an accelerometer sensor, motion sensor, magnetic sensor, positioning and tracking sensors, and other sensors that are capable of tracking and monitoring the movements of a user within an indoor or an outdoor environment. Note that the user device 105 may be representative of a plurality of user devices communicating with the electronic locking system 100, the electronic lock 101, and/or the geo-fence 109.


The electronic lock 101 is a device that has an electronically controlled latch that can be actuated directly to a locked position to prevent or unlocked position to allow communal access for the user 103 to a secure storage in order to keep the user belongings secure. The electronic lock 101 may include the computing device including the processor for communicating with other systems and sub-systems through any network communication technologies, such that the automatic notifications are generated and provided to the user 103. The electronic lock 101 may alternately be a type of electronic lock that can hold a traditional mechanical key to be used in a mechanical lock and where the latch movement of locked and unlocked is related to a key container position. The electronic lock 101 also may be in the form of a device or system associated with a real property of the user 103. The electronic lock 101 is installed in a storage space of the real property belonging to or rented by the user.


The geofence environment is a proximity system, virtual perimeter, and/or geo-fence threshold. The geo-fence environment can be temporarily or dynamically generated around a geographic location and/or be a predefined set of boundaries, as in a radius around the electronic lock 101 (e.g., geo-fence 109) or as in property and municipal boundaries. The geo-fence may be a set of latitude and longitude coordinates that in combination describe a boundary around the real property. The geo-fence may be contiguous, or it may cover only the exit points from the real property. The geo-fence may also be defined by structural metadata (e.g., data regarding the design and specification of the geo-fence) and/or descriptive metadata (e.g., data particular to individual property). Note that the geo-fence 109 is only one example of a geo-fence environment and is not intended to suggest any limitation as to the scope of use or operability of embodiments of the invention described herein (indeed additional or alternative components and/or implementations may be used). Geo-fences can be generated and monitored by any detection, communication, and/or location technology, such as global positioning systems (“GPS”), radio frequency identification (“RFID”), near field communication (“NFC”), short wave radio, proximity systems, Bluetooth Low Energy (BLE) beacons, Ultra-wideband (UWB) systems, etc.


Further, the geo-fence environment is utilized by the user device 105 to detect actions and/or movements of the user device 105. For example, at some distance from the property or the electronic lock 101 defined by the geo-fence environment (e.g., 150 meters), the electronic locking system 100 can initiate an automatic real-time notification to the user 103, without the need for the user 103 of the user device 105 to interact with the electronic lock 101. Further, the real-time notification can also indicate the current location of the user as determined by the user device 105, or it may simply indicate that the user has left the property.


The communication gateway 107 may comprise a single, local network, a large network, or a plurality of small or large networks interconnected together. The communication gateway 107 may also comprise any type or number of local area networks (LANs) broadband networks, wide area networks (WANs), and a Long Range Wide Area Network (LoRaWAN), etc. Further, the communication gateway 107 may incorporate one or more LANs, and wireless portions and may incorporate one or more of various protocols and architectures such as TCP/IP, Ethernet, etc. The communication gateway 107 may also incorporate other types of public networks, such as the public switch telephone network (PSTN) or the like. The communication gateway 107 may further include a network interface to communicate via offline and online wireless communication with networks, such as the Internet, an Intranet, and/or a wireless network, such as a cellular telephone network, a wireless local area network (WLAN), personal area network, and/or a metropolitan area network (MAN). The wireless communication may use any of a plurality of communication standards, protocols, and technologies, such as LTE, 5G, beyond 5G networks, Wireless Fidelity (Wi-Fi) (such as IEEE 802.11, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, and/or any other IEEE 802.11 protocol), voice over Internet Protocol (VoIP), Wi-MAX, Internet-of-Things (IoT) technology, Machine-Type-Communication (MTC) technology, a protocol for email, instant messaging, and/or Short Message Service (SMS) and LoRaWAN.


An example of a set of operations performed by the electronic locking system 100 for providing real-time notifications will be described with reference to FIG. 2 of the drawings. FIG. 2 illustrates a flowchart of method steps performed by the electronic locking system 100 for providing automatic real-time notifications to the user 103 ensuring the security of the storage space or the real property, according to one or more embodiments. The method 200 begins at the step 201.


At step 201, the electronic locking system 100 detects whether a user 103 is leaving a storage space secured by the electronic lock 101. The electronic locking system 100 detects a change in position of the user 103 based on sensor data of a sensing unit associated with a user device 105. As a non-limiting example, the sensing unit such as, but not limited to, an accelerometer sensor starts monitoring movements of the user device 105. Once the user 103 pulls down the storage space shutter, the accelerometer sensor captures the movement of the user device 105. The sensed movement of the user can be referred as the sensor data without any deviation from the scope of the invention. The flow of the method 200 now proceeds to (step 203).


At step 203, the electronic locking system 100 determines whether the latch 101A of the electronic lock 101 is showing an open status. The current state or status of the latch is determined by the electronic locking system 100 by the electronic lock 101 sensor that senses the latch as open or closed. The current state is physically displayed by a latch status indicator 101B. The latch status indicator 101B has two colors. The first color of the latch status indicator 101B indicates an unlocked state of the latch 101A, and the second color of the latch status indicator 101B indicates a locked state of the latch 101A. Additionally, the current state is also electronically advertised by the electronic lock 101 by the latch status indicator 101B sending a Bluetooth or Ultra-Wideband (UWB) message or advertisement with data indicating the current status of the latch. The flow of the method 200 now proceeds to (step 205).


At step 205, the electronic locking system 100 monitors a change in location of the device 105 with respect to the electronic lock 101 when it is determined the latch 101A of the electronic lock 101 is in the open status. A first monitoring process detects whether the location of the device 105 is within or at a threshold level of a communication range of the electronic lock 101. The communication range of the electronic lock 101 corresponds to a Bluetooth range or an Ultra-Wideband (UWB) range of the electronic lock 101. The first detection process is performed based on a received Signal Strength Indicator (RSSI) by the mobile device 105. The first detection process also includes determining the last known state of the electronic lock 101 latch as still being unlocked or open.


According to an embodiment of the disclosure, when it is determined the latch 101A of the electronic lock 101 is closed the electronic locking system 100 disables or stops the monitoring of the change in location of the device 105 with respect to the electronic lock. The flow of the method 200 now proceeds to (step 207).


At step 207, the electronic locking system 100 displays a first alert notification on an application of the user device 105 based on a result of the first monitoring process, when it is determined that the location of the device is at a threshold level of the communication range. The first alert notification indicates a last known status of the latch 101A. As a non-limiting example, the last known state of the latch 101A may correspond to the unlocked or open state of the latch 101A. The flow of the method 200 now proceeds to (step 209).


At step 209, the processor or controller of the electronic locking system 100 detects whether any user response is received from the user device 105 in response to the sent first alert notification. The flow of the method 200 now proceeds to (step 211). The processor or controller of the electronic locking system 100 may corresponds to one of a processor or controller of the electronic lock 101 or a processor or controller of the user device 105.


At step 211, the electronic locking system 100 determines, in a case where it is detected that any user response is not received from the user device 105 in response to the sent first alert notification, a second monitoring process to re-determine whether the location of the device is within or out of a geofence. The detection of the geofence may be done by the user device 105. The flow of the method 200 now proceeds to (step 213).


At step 213, the electronic locking system 100 displays a second alert notification to the application of the user device 105 based on a result of the second detection process that indicates that the location of the device is out of geofence. The second alert notification also indicates the last known status of the latch 101A. As a non-limiting example, the last known state of the latch 101A may correspond to the unlocked or open state of the latch 101A.


In one or more embodiments, the electronic locking system 100 may also determine a time period for which the latch status is still open and sends a message to a cloud server and the cloud server sends a third notification alert to the user device 105 indicating that the electronic lock is still unlocked. It is to be noted that the third notification alert may be sent to user device 105 before the first alert and second alert notifications, in between the first alert and second alert notifications, or after the first alert and second alert notifications.


Referring now to FIG. 3 illustrates a detailed flowchart of the method steps that are performed by the electronic locking system for providing the automatic real-time notifications to the at least one user, according to one or more embodiments of the disclosure. FIG. 3 depicts a method 300 depicting a stepwise explanation for providing the automatic real-time notifications to the at least one user. The method 300 begins at the step 301.


At step 301, the electronic lock 101 detects whether the user 103 (tenant) enters the storage space by accessing the electronic lock 101 based on a current status of an engagement or disengagement of the latch 101A of the electronic lock 101. The flow of the method 300 now proceeds to (step 303).


At step 303, the electronic lock 101 advertises the status of the latch 101A to the user device 105 and the user device 105 starts monitoring movements of the user 103 using the accelerometer sensor. Additionally, based on the movements, the electronic lock 101 provides advertisement status of the latch to the user 103. The flow of the method 300 now proceeds to (step 305).


At step 305, the user device 105 detects whether the user 103 is leaving the storage space based on sensor data of the sensing unit associated with a user device 105. Then the user device 105 monitors the change in its location with respect to the electronic lock 101 based on the result of the detection indicating the user 103 is leaving the storage space. As a non-limiting example, the sensing unit such as, but not limited to, an accelerometer sensor starts monitoring movements of the user device 105. Once the user 103 pulls down the storage space shutter, the accelerometer sensor captures the movement of the user device 105. The sensed movement of the user can be referred as the sensor data without any deviation from the scope of the invention. Accordingly, the user device 105 starts monitoring the change in its location with respect to the electronic lock 101. The flow of the method 300 now proceeds to (step 307).


At step 307, the user device 105 determines whether the user device 105 is at the threshold level of the communication range based on the monitoring of the user's location with respect to the electronic lock 101. The threshold level of the communication range corresponds to a very low level of Bluetooth range or a very low level of the UWB range. In particular, the user device 105 keeps monitoring the user's location with respect to the location of the electronic lock 101 once it is detected that the storage space shutter is pulled down by the user. The user device 105 monitors whether the user device 105 is at the threshold level of the communication range (e.g., whether the user is leaving the door, walking to the elevator 111A for down to the floor, to the parking area 111B, etc.) by tracking the location of the user 103 with respect to the electronic lock 101. As a non-limiting example, when a distance between the user 103 keeps on increasing i.e., (e.g., 15 meters→30 meters→50 meters, etc. and when it increases beyond the threshold distance range of the communication range, the user device 105 determines that the user 103 is moving out of the threshold level of the communication range. Moreover, the user device 105 determines whether the user is moving outside the communication range based on a decreasing signal strength indicator (RSSI) that correlates to a distance of the user device 105 away from the electronic lock 101. Once, the user device 105 detects whether the location of the user device 103 is within or at the threshold level of the communication range of the electronic lock 101. In case a result of the detection at step 307 is NO, then the flow of the method 300 now proceeds to (step 309).


At step 309, the user device 105 keeps tracking status of the latch 101A of the electronic lock 101 via advertisements. In particular, the user device 105 may keep monitoring the current state of the latch 101A periodically based on the result of the detection process that indicates that the location of the user device 105 is within the threshold level of the communication range. However, in case a result of the detection at step 307 is Yes, then the flow of the method 300 now proceeds to (step 311).


At step 311, the user device 105 displays the first alert notification to the user 103 via the application if the last known state of the latch 101A was open or unlocked and the user 103 is at the threshold level of the communication range, i.e., the very low level of the Bluetooth range and the very low level of the UWB range. The flow of the method 300 now proceeds to (step 313).


At step 313, the user device 105 detects whether any user response is received in response to the sent first alert notification. The user device 105 monitors the geofence 109 and checks the status of the latch 101A and display the current status of the latch to the user 103 on the application of the user device 105. The geofence 109 corresponds to a GPS-enabled communication range. The flow of the method 300 now proceeds to (step 315).


At step 315, the user device 105 detects whether the user 103 intends to close the electronic lock 101 by engaging the latch 101A or intends to leave it open on purpose by detecting whether any user response is received in response to the displayed first alert notification. In case a result of the detection at step 315 is NO, then the flow of the method 300 now proceeds to (step 317).


At step 317, the user device 105 further continuously monitors the geofence 109 of the electronic lock 101 in absence of any user response in response to the displayed first alert notification. The flow of the method 300 now proceeds to (step 319).


At step 319, the user device 105 again determines whether the user 103 is moving away from the geofence 109 based on the monitoring of the user location with respect to the electronic lock 101 using any detection, communication, and/or location technology, such as global positioning systems (“GPS”), radio frequency identification (“RFID”), near field communication (“NFC”), short wave radio, proximity systems, Bluetooth Low Energy (BLE) beacons, etc. In case the result of the determination at step 319 is NO, then the electronic lock 101 keeps monitoring the geofence 109 until the result of the determination at step 319 becomes Yes. However, in case a result of the determination at step 319 is Yes, then the flow of the method 300 now proceeds to (step 321).


At step 321, the user device 105 displays a second alert notification to the user 103 on the application of the user device 105 indicating the last known status of the latch 101A. As a non-limiting example, the second alert notification may indicate that the latch of the electronic lock is still open. The flow of the method 300 now proceeds to (step 323).


At step 323, the user device 105 again detects whether the user 103 intends to close the electronic lock 101 by engaging the latch 101A or intends to leave it open on purpose by detecting whether any user response is received in response to the displayed second alert notification.


Further, in case a result of the detection at step 315 or step 323 is yes, then the flow of the method 300 now proceeds to (step 325). At step 325, the user device 105 may send the indication of the user to the cloud device 115 to be stored in the cloud along with other audit information. The electronic lock 101 may also send indication to the cloud device 115 when the latch 101A is opened or closed. The electronic lock 101 send the indication to the cloud device 115 using an established LoRaWAN connection with the cloud device. The electronic lock 101 may also send the indication as a message over LoRaWAN protocol to a gateway which then sends the message to the cloud device 115. The user device 105 may send the indications of the user when it displays alert notifications to the user indicating the latch 101A is open, closed, or has an error. The user device may also send the user response received in response to any of the displayed first alert notification or the displayed second alert notification to the cloud device 115.


The cloud device 115 may include a database that has a unified audit log. The unified audit log may indicate one or more events including, but are not limited to, the user device 105 has requested to open the latch 101A, the electronic lock 101 is actually opened, the user device 105 is at the threshold level of the communication range, the user device prompted the user 103 for the second time indicating the status of the latch 101A, no user response is received in response to the prompted attempt, the user 103 has provided a response to leave the electronic lock 101 open on purpose, the user 103 has provided a response close the electronic lock 101, or the electronic lock 101 sends a notification message indicating that it is still open or closed.


According to an embodiment of the disclosure, when the cloud device 115 receives the indication regarding the status of the latch 101A from the electronic lock that it is closed. Then the cloud device 115 may also send a message to the user device 105 indicating the updated status of the latch 101A, or the cloud device 115 may simply record the status of the latch 101A indicated in the received indication. At some point of time, the cloud device 115 may send the message to the user device 105 indicating the updated status of the latch 101A to the user device when a request to know the latest status of the latch 101A is received from the user device 105. Further, when the user device 105 receives the message having indication that the latest or updated status of the latch 101A is now closed, then the user device 105 may also decide to stop or disable the monitoring of the change of location or the geofence 109.


Also, the user device 105 may also stop monitoring the geofence 109 of the electronic lock 101 when it receives a user response in response to the displayed first alert notification indicating that the user 103 intends to leave the electronic lock 101 open on purpose.


According to some embodiment, the processor or controller of the electronic lock 101 or the user device 105 may also store the second alert notification in the cloud device 115 as a second event. Also, each time when the status of the latch 101A is changed by the user 103, the processor or controller of the electronic lock 101 stores the changed status of the latch in the cloud device 115 as the last known status of the latch 101A.


According to some embodiment, the processor or controller of the electronic lock 101 may also send the second alert notification to a device of the administrator 113 indicating the last known status of the latch 101A.


In one or more embodiments, the processor or controller of the electronic lock 101 may also notify the device of the administrator 113 indicating which door of the facility or the real property of the user 103 is left open when the door shutter is pulled but latch 101A of the electronic lock 101 is not engaged.


In one or more embodiments, the first, second, and third alert notification may correspond to a push alert notification without any deviation from the scope of the invention disclosed herein.


According to the one or more embodiments disclosed herein, based on the results of the detection processes that indicate that the location of the device is at the threshold level of the Bluetooth range or the UWB range and in absence of the user response to the previous alert notifications, the processor or controller of the electronic lock 101 may keep sending the alert notifications to the application of the user device 105 until the current status of the latch 101A changes from the unlocked state to the locked state.

Thus, the electronic locking system and/or elements thereof may be implemented as computer-readable program instructions on one or more computing devices, stored on a computer-readable storage medium associated therewith. A computer program product may comprise such computer-readable program instructions stored on the computer-readable storage medium for carrying and/or causing a processor to carry out the operations of the electronic locking system. The electronic locking system, as implemented and/or claimed, improves the functioning of a computer and/or the processor itself by enabling a seamless user experience between the user property (i.e., secure storage), the electronic lock, and the user device system through direct computations of user positions and directions that are further utilized to deliver faster and more automatic real-time notifications.


The technical effects and benefits include providing notifications to the users if they left the door unlocked before they leave the real property or secure storage facility.


Further, the technical effects and benefits include securing the storage space by providing automatic real-time notification reminders indicating the last known status of the latch 101A of the electronic lock. For example, the automatic real-time notification reminders may indicate “Last time I saw your lock is unlocked, are you sure you locked it?” In this way, it helps in securing the storage space by reminding the users each time they leave the real property or secure storage unlocked. Those skilled in the art will appreciate that the aforementioned example of the automatic real-time notification reminders is merely exemplary and is not intended to limit the scope of the invention.


Further, the technical effects and benefits include enabling more accurate notification reminders. The electronic lock 101 keeps reminding the user periodically until it receives a response from the user indicating that he/she intends to leave the secure storage facility open on purpose. In this way, an improvement in the enabling of more accurate notification reminders to the user is performed by the electronic locking system.


The technical effects and benefits also include feeding each of the alert notification into the cloud device 115 as an event for the record which is specifically helpful in cases like user want to check at which time these facilities were accessed and also helps in knowing the last events at which the secure storage facility or the real property left open.
