DESC:Field of the Invention
[0001] The present disclosure relates to systems and methods for notifying about an anomaly or hazard within an environment.

Background
[0002] Typically, notification systems implemented for the security of environments, such as, for example, a home, an office, a laboratory, and the like, notify a pre-registered user terminal about the occurrence of an anomaly, hazard, or emergency. For instance, a house owner may implement such a system and may register his mobile with the notification system to receive such alerts. On detection of the occurrence of an anomaly, a message or a call may be placed to the mobile.
[0003] However, such a system may not be efficient for varied reasons. As an example, there may be a situation where the house owner is not having his/her mobile in his vicinity. In such a case, in case an emergency, hazard, or anomaly has occurred in a distant room, the house owner may not learn about the same in time. This may prove to be fatal for the house owner.
[0004] Therefore, there is a need for a solution to address at least one of the aforementioned deficiencies.

Summary
[0005] This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the invention. This summary is neither intended to identify key or essential inventive concepts of the invention and nor is it intended for determining the scope of the invention.

[0025] Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
[0026] Fig. 1 illustrates a notification system 100 configured to alert users about anomaly events occurring within an environment, according to an embodiment of the present disclosure. In an example, the notification system 100 includes a gateway 102, at least one sensor 104, and at least one electrical controller 106. According to aspects of the present disclosure, the notification system 100 may be implemented within an environment, such as, for example, a home, an office space, a lab, and the like. In an example embodiment, the notification system 100 may be operable to provide a notification in case an anomaly within the environment is detected.
[0027] In an example, the gateway 102 may include one or more of a microprocessor, a processor, a microcontroller, and a state machine. As would be appreciated, one or more of the aforementioned entities may operate together to realize the functions of the gateway 102, as described herein. Furthermore, the gateway 102 may also include a wireless communication unit (not shown) for transmitting and receiving data from other devices, or the internet.
[0028] Examples of the at least one sensor 104 may include, but are not limited to, a gas sensor, a fire sensor, a smoke sensor, and a motion sensor. Examples of the electrical controller 106 may include, but are not limited to, an electrical adapter and an electrical switch. In an example, the at least one electrical controller 106 may be coupled to an electrical appliance 108. Examples of the electrical appliance 108 may include, but are not limited to, a Television (TV), a fridge, an Air Conditioner (AC), a music system, a ceiling lamp, a floor lamp, an air purifier, a blender, and the like, and an alarm.
[0029] In an example, the at least one electrical controller 106 may include a wireless communication unit (not shown in the figure), a processor (not shown in the figure), and one or more electrical circuitry (not shown in the figure). The one or more electrical circuitry is configured to supply electrical power from mains to the corresponding electrical appliance 108 that is coupled to the at least one electrical controller 106. In an example, the controller is configured to control the operation of the one or more electrical circuitry, for example, using a relay, to control the switch ON/OFF of the electrical appliance 108. Furthermore, in an example, the wireless communication unit may be configured to receive and send wireless communication messages that may include control signals, operational signals, data, etc.
[0030] As is further shown in the figure, the gateway 102 may be communicatively coupled to a storage 110. The storage 110 may include one or more of non-volatile memories, such as flash memory, read-only memory (ROM), ferroelectric RAM, most types of magnetic computer storage devices (e.g. hard disk drives, floppy disks, and magnetic tape), and optical discs. Although shown external to the gateway 102, but in an example, the gateway 102 may include the storage 110.
[0031] The storage 110, in an example, may include a sensor database and an electrical controller database. In an example, the sensor database may include a sensor ID and location information corresponding to the at least one sensor 104. Furthermore, in an example, the electrical controller database may include location information corresponding to each of a plurality of electrical controllers, such as the at least one electrical controller 106.
[0032] In an example embodiment, the sensor database may be populated with said information during an initial registration process. In said process, a user may use a user terminal 112 that is coupled to the storage 110, to register the at least one sensor 104. For instance, an app may be used wherein the user may select a location where a given sensor is deployed. Accordingly, the information about the location of the sensor may be mapped with a sensor identity (ID), and this mapped information may be stored in the sensor database of the storage 110. Likewise, all the electrical controllers 106 that are deployed in the environment may be mapped with their locations and stored in the electrical controller database of the storage 110. As an example, the user may install the electrical controllers 106 at different locations and may register the locations using an app of the user terminal 112. This mapped relationship of the electrical controllers 106 and their location is stored as the electrical controller database in the storage 110.
[0033] In an example, the user may install a plurality of sensors, such as the sensor 104 in the environment. As may be understood, the sensors 104 may be installed as per the operation of the sensor. For example, a fire sensor may be installed near a kitchen area and so on. According to an example embodiment, at least one sensor 104 may be configured to detect an anomaly event within the environment. Without limitation, the term anomaly event may be understood as occurrence of an anomaly, such as unexpected fire, smoke, movement, noise, etc. For example, the fire alarm may detect fire around its location within the environment, the gas sensor may detect the presence of a gas around its location within the environment, and so on and so forth. On detecting the anomaly, the at least one sensor 104 may be configured to transmit a status message to the gateway102. The status message may be understood as being indicative of the occurrence of the anomaly event. In an example, the status message may include a sensor ID of the at least one sensor 104.
[0034] In an example embodiment, the status message may be received by the gateway 102. In an example, the gateway 102 may be configured to ascertain a location of the at least one sensor 104. To that end, the gateway 102 may query the sensor database stored in the storage 110. In the query, the gateway 102 may include a sensor ID of the sensor 104, as identified by the gateway 102 from the status message. As explained above, the sensor database may include the sensor IDs and corresponding locations of the sensors deployed within the environment. Thus, by querying the storage 110, the gateway 102 may determine the location of the sensor 104.
[0035] Once the location of the at least one sensor 104 is ascertained by querying the storage 110, the gateway 102 may be configured to identify at least one electrical controller 106. In an example embodiment, the at least one electrical controller 106 may be identified based on a location of the at least one electrical controller 106. In an example, the at least one electrical controller 106 which has the same location as that of the at least one sensor 104 may be identified. In other words, in an example, if a sensor detects fire in room A, then an electrical controller present in room A would be identified.
[0036] In another example, the at least one electrical controller 106 which has the same location as that of the user terminal 112 may be identified. In other words, in an example, if a sensor detects fire in room A and the user is in room B, then an electrical controller present in room B would be identified. In said example, the gateway 102 may be operable to obtain the location of the user terminal 112. In an example, the gateway 102 may be operable to obtain the location of the user terminal 112 periodically.
[0037] In yet another example, both, the at least one electrical controller 106 present at the location of the at least one sensor 104 and the at least one electrical controller 106 present at the location of the user terminal 112 may be identified. For instance, both, the electrical controller of room A and the electrical controller of room B may be identified.
[0038] The determination as to corresponding to which location the at least one electrical controller 106 is to be identified may be user selectable. For instance, the user may choose to get notified via the electrical appliance 108 which may be present at the location of the anomaly. In such a case, the user may select an option whereby the electrical controller 106 present at the location of the at least one sensor 104 is selected. In another case, the user may choose to get notified via the electrical appliance 108 which may be present at the location of the user terminal 112. In such a case, the user may select an option whereby the electrical controller 106 present at the location of the user terminal 112 is selected. In yet another example, the user may choose to get notified via the electrical appliance 108 which may be present at the location of the anomaly and the electrical appliance 108 which may be present at the location of the user terminal 112. In such a case, the user may select an option whereby the at least one electrical controller 106 present at the location of the at least one sensor 104 and the at least one electrical controller 106 present at the location of the user terminal 112 is selected.
[0039] Continuing with the above, for identification of the at least one electrical sensor 106, the gateway 102 may query the electrical controller database stored in the storage 110. In an example, the querying may be based on the user-selected option as described above. Accordingly, the at least one electrical controller 106 may be identified based on the location of the at least one electrical controller 106. In a further example, the gateway 102 may learn about the location of the user terminal 112, based on conventional positioning techniques. For instance, Wi-fi triangulation or GPS positioning based methods may be implemented and the location of the user terminal 112 may also be stored in the storage 110 by the gateway. Thus, in the above embodiments, the gateway 102 learns about the location of the user terminal 112 from the information stored in the storage 110.
[0040] Once the at least one electrical controller 106 is identified, the gateway 102 may be operable to transmit a control signal to the at least one electrical controller 106 to control the operation of the electrical appliance 108 connected to the at least one electrical controller 106. In an example, the gateway 102 may transmit the control signal wirelessly to the electrical controller 106. On receiving the control signal, the at least one electrical controller 106 may switch ON the electrical appliance 108. This, abrupt switching ON of the electrical appliance 108 may serve as a notification and accordingly, the user may be made aware of the anomaly or hazard. In an example, the control signal may be of a type such that the electrical appliance 108 is only switched ON. In another example, the control signal may be of a type, such that repeated switching ON-OFF of the electrical appliance 108 may be performed by the at least one electrical controller 106.
[0041] In an example embodiment, if the gateway 102 ascertains that the location of the user terminal 112 is more than a predetermined distance away from the at least one sensor 104, the gateway 102 may not transmit the control signal to the at least one electrical controller 106. For instance, it may be determined that the user terminal is more than 50 meters away from the at least one sensor104. In such a case, it may be presumed that the user is not in the house and accordingly, the gateway 102 does not transmit any control signal to the at least one electrical controller 106.
[0042] Fig. 2 illustrates a method 200 of alerting users about anomaly events occurring within an environment, according to an embodiment of the present disclosure. In an example, the method 200 may be implemented in an environment using components as described above in Fig. 1 and further illustrated in Fig. 3.
[0043] At step 202, the method 200 comprises detecting an anomaly event within an environment. In an example, at least one sensor, such as the sensor 104, may detect the anomaly. The environment may include, for example, a home, an office, a lab, and the like. The anomaly may be, for example, a fire, a smoke, a gas leak, an abrupt motion, and the like.
[0044] At step 204, the method comprises receiving, by a gateway, a status message indicative of the occurrence of the anomaly event from the at least one sensor. In an example, the at least one sensor may transmit the status message to the gateway present within the environment. In an example, the status message may include a sensor identity (ID). The gateway, in an example, is communicatively coupled to the at least one sensor and at least one electrical controller present within the environment. The at least one electrical controller is furthermore operable to control operation, i.e., switching ON/OFF, of an electrical appliance.
[0045] At step 206, at least one electrical controller from a plurality of electrical controllers present within the environment is selected by the gateway. In an example, the selection of the at least one electrical controller may be based on the location of the sensor, or the location of a user terminal of a user, or both.
[0046] In an example, the selection of the at least one controller may be performed in a first manner. Herein, in an example, the method includes identifying the sensor ID of the at least one sensor based on the status message. Furthermore, the method includes determining a location of the at least one sensor using a sensor database. The sensor database includes a sensor ID and location information corresponding to the at least one sensor. The method further includes identifying at least one electrical controller from the plurality of electrical controller whose corresponding location matches the location of the at least one sensor, based on an electrical controller database. The electrical controller database includes location information corresponding to each of the plurality of electrical controllers. Subsequently, the method includes selecting the identified at least one electrical controller.
[0047] In an example, the selection of the at least one controller may be performed in a second manner. Herein, in an example, the method includes determining a location of a user terminal of a user. The method further includes identifying at least one electrical controller from the plurality of electrical controller whose corresponding location matches the location of the user terminal, based on an electrical controller database. The electrical controller database including location information corresponding to each of the plurality of electrical controllers. Furthermore, the method includes selecting the identified at least one electrical controller.
[0048] In an example, the selection of the at least one controller may be performed in a third manner, which is a combination of the first manner and the second manner. In said third manner, an electrical controller present at the sensor location and an electrical controller present at the location of the user terminal may be selected, as explained above in Fig. 1.
[0049] At step 208, a control signal is transmitted to at least one electrical controller to trigger operation of an electrical appliance coupled to the selected at least one electrical controller. In an example, the gateway may transmit the control signal. In an example, the control signal is such that the electrical appliance is only switched ON. In another example, the control signal is such that the electrical appliance is switched ON-OFF, as per a predetermined pattern.
[0050] At step 210, the electrical controller controls switching ON/OFF of the electrical appliance. Herein, the switching ON/OFF of the electrical appliance is a notification relative to the occurrence of the anomaly or hazard. In an example, where the at least one electrical controller is an electrical adapter, a relay thereof may be controlled. Accordingly, the electrical appliance may be switched ON or switched OFF. This, in turn, serves as a notification and the user may be made aware of the occurrence of the anomaly. In an example embodiment, the method 200 further includes identifying the sensor ID of the at least one sensor based on the status message. Furthermore, the method includes determining a location of the at least one sensor using the sensor database. Furthermore, the method includes transmitting an alert message including the determined location of the at least one sensor to a user device of a user.
[0051] Furthermore, in an example embodiment, the method 200 includes, determining a location of a user device of a user. Furthermore, the method includes determining whether the location of the user device is more than a threshold distance away from the at least one sensor. Furthermore, the method includes discarding transmission of the control signal when the location of the user terminal from the at least one sensor is more than the threshold distance. The method further includes determining a location of the at least one sensor using the sensor database. Furthermore, the method includes transmitting an alert message including the determined location of the at least one sensor to the user device of the user.
[0052] Fig. 3(a) illustrates a schematic block diagram of the gateway 102, according to an embodiment of the present disclosure. Fig. 3(b) illustrates a schematic block diagram of the electrical controller 106, according to an embodiment of the present disclosure. As is shown, both, the gateway 102 and the electrical controller 106 may include a processor 302, a wireless communication unit 304, and data 306. Furthermore, the electrical controller 106 includes electrical circuitry 308, as well. In an example, the aforementioned components of the gateway 102 and the electrical controller 106 may be configured to perform the associated operations and functions as described above in Fig. 1 and Fig. 2.
[0053] Figs. 4(a)-(b) illustrates a plurality of use cases, according to embodiments of the present disclosure. As shown in the use case of Fig. 4(a), a user 404 and corresponding user terminal 406 are within a house comprising three rooms. Accordingly, in the event that the sensor 104 may detect an anomaly event, the gateway 102 may raise an alert as described above by transmitting control signals to at least one electrical controller 106 (not shown). Suppose, the anomaly occurs in Room 1. As described herein, the at least one electrical controller that is selected may be an electrical controller coupled to lamp 402-1 of room 1, or may be an electrical controller coupled to television 402-3 of room 3, or both. In a further embodiment, referring to fig. 4(b), in case the user is more than a predefined threshold distance away, then only a notification may be sent to the user terminal 406. In an example, the user terminal 406 may be registered by the user with the gateway 102. For instance, an application may be installed by the user and using a common Wi-Fi connection, the user terminal 406 may be registered. Without limitation, notifications to the user terminal 406 may be provided to the user over the internet.
[0054] While specific language has been used to describe the present subject matter, any limitations arising on account thereto, are not intended. As would be apparent to a person in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein.
