This disclosure relates generally to security systems and, more specifically, to security systems configured to detect earthquakes and provide appropriate warnings.
Security systems are widely used to protect property and provide personal safety. Security systems generally include a control unit that controls the overall operation of the system, one or more keypads providing user access to the system, and various detectors and sensors.
Security systems may generate an alarm in response to any number of events, such as an unauthorized entry, fire, medical emergency, or manual alarm activation. The security system may be associated with a service that remotely monitors the status of the security system. Thus, if the security system generates an alarm, a notification signal may be transmitted via a wired and/or wireless communications link to a monitoring system. Upon receiving the notification, security service personnel for the monitoring system may attempt to contact the property owner or other party at the facility to verify the alarm. If it is appropriate to do so, a security service representative may, upon confirmation of the alarm, contact an emergency response agency such as the police department, the fire department, an emergency medical team, or other appropriate entity.
For those living in earthquake zones, the threat of an earthquake is a frequent source of worry. While some dangerous natural events, such as hurricanes, can be forecast with some accuracy, earthquakes remain alarmingly unpredictable. It would be desirable to have a security system that can detect and provide notification of an earthquake to users of the security system.
Disclosed herein are devices and approaches to notifying persons of an imminent earthquake. In one embodiment, a security system includes a control unit that is communicatively coupled to a plurality of sensors and is configured to receive alarm condition messages from those sensors. The sensors may send the alarm condition messages to the control unit if the sensors sense one or more alarm conditions. The system may also include an earthquake sensor that senses earthquake conditions and sends an earthquake condition message to the control unit in response. The earthquake sensor may, for example, sense the primary waves that precede the more destructive waves in an earthquake. The earthquake sensor may be installed at the same location as the control panel.
The control panel may cause an alarm module for the security system to generate an alarm when the control panel receives the earthquake condition message from the earthquake sensor. The alarm may include an audio component (such as a siren, audio instructions, etc.) and a visual component (such as flashing lights, text warning, etc).
The security system may also include a remote earthquake module that is configured to receive earthquake condition notifications from a number of control units. The remote earthquake module may be implemented as part of a monitoring system that is associated with the control unit and that communicates with the control unit over a cellular network. The control unit may transmit earthquake condition notifications to the remote earthquake module when the control unit receives an earthquake condition message from the earthquake sensor. The control unit may also receive earthquake alert messages from the remote earthquake module and generate an alarm in response.
In certain embodiments, the control unit may be communicatively connected to other, additional control units for separate security systems. The control unit may send an earthquake alert message to addresses for the additional control units if the earthquake sensor associated with the control unit senses an earthquake. The control unit may also be configured to receive earthquake alert messages from the additional control units and to generate an alarm in response.
In one embodiment, the present systems and methods may be embodied as a control unit. The control unit may include a sensor module that is communicatively coupled to sensors and configured to receive alarm condition messages from those sensors if the sensors detect an alarm condition. The control unit may also include an earthquake response module that is communicatively coupled to an earthquake sensor installed at the same facility as the control unit. The earthquake response module may be configured to receive an earthquake condition message from the earthquake sensor if the earthquake sensor detects an earthquake condition. An alarm module of the control panel may generate an alarm if the earthquake response module receives the earthquake condition message.
The earthquake response module may be communicatively coupled to a remote earthquake module implemented within a monitoring system by a cellular network, the Internet, or other appropriate communication link. The earthquake response module may receive earthquake alert messages from the remote earthquake module, and the alarm module may generate an alarm in response. The earthquake response module may send earthquake alert messages to the remote earthquake module if it receives an earthquake condition message from the earthquake sensor.
In certain embodiments, the control unit may include a network module that maintains the control unit as a node in a network of control units. The earthquake response module may be configured to receive earthquake alert messages from at least one of the control units in the network, and the alarm module may be configured to generate an alarm in response to the earthquake response module receiving such a message. The earthquake response module may also be configured to send earthquake alert messages to one or more of the control units in the network when the earthquake sensor associated with the earthquake response module detects an earthquake condition.
Also disclosed is a method for sensing an earthquake condition. The method may involve monitoring the sensors in the security system for alarm condition messages and monitoring an earthquake sensor installed at the location of the security system for earthquake condition messages. The method may also involve generating an audible alarm in response to receiving the earthquake condition message, and sending an earthquake condition notification to a remote server. The method may further involve sending the earthquake alert message to a separate control unit over a network of control units. Similarly, the method may involve receiving an earthquake alert message from a separate control unit over a network of control units. The method may also involve receiving an earthquake alert message from the remote server and generating a visual alarm in response.
A security system is also described. The system may include means for monitoring one or more sensors in a security system for alarm condition messages, means for monitoring an earthquake sensor installed at a location of the security system, means for generating an audible alarm in response to the earthquake sensor detecting an earthquake condition, and means for sending an earthquake condition notification to a separate control unit over a network of control units.

However, the exemplary embodiments described herein are not intended to be limited to the particular forms disclosed. Rather, the instant disclosure covers all modifications, equivalents, and alternatives falling within the scope of the appended claims.
Referring in general to the accompanying drawings, various embodiments of the present systems and methods are illustrated to show the structure and methods for installing a component within a system, such as a security system. Common elements of the illustrated embodiments are designated with like numerals. It should be understood that the figures presented are not meant to be illustrative of actual views of any particular portion of the actual device structure, but are merely schematic representations, which are employed to more clearly and fully depict embodiments of the present systems and methods.
The following provides a more detailed description of ways to implement the present systems and methods and various representative embodiments thereof. In this description, functions may be shown in block diagram form in order not to obscure the present disclosure in unnecessary detail. Additionally, block definitions and partitioning of logic between various blocks is exemplary of a specific implementation. It will be readily apparent to one of ordinary skill in the art that the present systems and methods may be practiced by numerous other solutions. For the most part, details concerning timing considerations and the like have been omitted where such details are not necessary to obtain a complete understanding of the present systems and methods and are within the abilities of persons of ordinary skill in the relevant art.
In this description, some drawings may illustrate signals as a single signal for clarity of presentation and description. It will be understood by a person of ordinary skill in the art that the signal may represent a bus of signals, wherein the bus may have a variety of bit widths and the present systems and methods may be implemented on any number of data signals including a single data signal.
Sensors 101 monitor for certain events and report relevant events to the control unit 102. Sensors 101 may include any of a variety of different types of sensors, such as door and window sensors, motion sensors, glass break sensors (e.g., sensors that detect a physical break or detecting the sound of a glass break), etc. The control unit 102 may be configured to monitor sensors 101 for alarm conditions via communication links 104 and to relay alarms to the monitoring system 103 via communication link 106. The sensors 101 may, in response to detecting an alarm condition, send an alarm condition message to the control unit 102.
Control unit 102 may include sensor monitoring module 111, user interface 112, and alarm module 113. Sensor monitoring module 111 is configured to monitor sensors 101. Sensors 101 can sense and/or indicate a change in their physical surroundings (e.g., a normally closed connection becomes open, a signal indicating that the sound of breaking glass was detected, etc.) which may be indicative of an unauthorized access, fire, or other event. The sensors 101 may communicate messages on communication links 104. For example, a circuit connected to a door sensor 101 can transition from closed to open (or to a resistance exceeding a pre-determined resistance threshold) indicating that a door has been opened. A motion sensor 101 can send an electrical signal indicative of detected motion. Sensor monitoring module 111 may monitor communication links 104 for alarm condition messages sent from sensors 101. Upon sensor monitoring module 111 receiving an alarm condition message signaling occurrence of an alarm condition, sensor monitoring module 111 may send a signal to alarm module 113.
The alarm module 113 may validate the alarm condition has occurred before communicating with the monitoring system 103 or generating an alarm using the alarm 116. For example, the alarm module 113 may validate an alarm condition indicating that a window is open when the security system is on, but may not validate the same alarm condition when the security system is off.
The alarm module 113 may cause an alarm 116 to generate an alarm in response to validating the alarm condition has occurred. The alarm 116 may provide an audio signal (such as beeping, audio instructions, or other suitable audio), a visual signal (such as a flashing light) or a combination thereof to alert a user to the alarm condition. Where the control unit 102 is associated with one or more controllers providing home automation features, the control unit 102 may also use those features to provide an alarm. For example, the control unit 102 may flash one or more interior lights as part of the alarm.
User interface 112 can include an input interface and an output interface. The input interface can include a physical input interface or virtual input interface that may include a numeric key pad (e.g., for entering a disarm code, etc.), sensor activation buttons, physical duress buttons, or other input/output devices. The input interface can include a condenser for receiving audio input and/or communicating with monitoring system 103. The output interface may include an output display device that displays system status, such as armed and disarmed, sensors/zones that have detected change in physical surroundings, and other relevant information. The output interface can also include a speaker that audibly outputs information similar to that displayed on the output display device. The speaker can also be used by monitoring system 103 to communicate with a user of control unit 102. Other input/output approaches may also be implemented as part of the user interface 112.
The control unit 102 may also communicate over a communication link 133 with a remote activation system 131. The remote activation system 131 may allow a user to interact with the control unit 102 remotely. For example, the user may be able to arm and disarm the system 100 from a mobile device such as a cellular phone using the remote activation system 131.
Generally, control unit 102 may operate under control of an operating system stored in memory 124, and interface with a user to accept inputs and commands and to present outputs through user interface 112. Control unit 102 may also implement a compiler (not shown), which allows one or more application programs (not shown) written in a programming language to be translated into processor 122 readable code. Instructions implementing an application program may be tangibly embodied in a non-transitory computer-readable medium. Further, an application program may include instructions which, when read and executed by processor 122, cause processor 122 to perform the steps necessary to implement and/or use embodiments of the present disclosure. It is noted that an application program and/or operating instructions may also be tangibly embodied in memory 140 and/or data communications devices, thereby making a computer program product or article of manufacture according to an embodiment the present disclosure. As a result, the term “application program” as used herein is intended to encompass a computer program accessible from any computer readable device or media. Furthermore, portions of the application program may be distributed such that some of the application program may be included on a computer readable media within control unit 102, and some of the application program may be included in a remote device, such as a remote computer.
The control unit 102 may thus be a component in a security system and/or a building automation system. The control unit 102 may provide security and/or automation functionality for a residence, an office, a building, or other appropriate space.
In many embodiments, the control unit 102 may be realized as a control panel. As used herein, the term “control panel” refers to a standalone, dedicated unit for providing security and/or building automation functionality. The term “control panel” does not include a general purpose computer, smart phone, tablet, or other general purpose device that may run an application providing some security/automation functionality.
The control unit 102 may further include an earthquake response module 200. The earthquake response module 200 may be software, firmware, hardware, or a combination thereof. The earthquake response module 200 communicatively couples with an earthquake sensor that is installed at the same facility as the control unit 102. The earthquake response module 200 receives an earthquake condition message from the earthquake sensor, and provides an appropriate alarm to warn those at the facility of the earthquake.
The earthquake sensor 302 detects one or more earthquake conditions 312 that indicate that an earthquake is occurring. In response to detecting an earthquake condition 312, the earthquake sensor 302 sends an earthquake condition message 320 to the control unit 102 in response to detecting the earthquake condition 312. The earthquake condition message 320 is a message that at least indicates that the earthquake sensor 302 has sensed an earthquake condition 312.
The earthquake sensor 302 may, for example, detect waves generated by an earthquake. An earthquake generates primary waves (also known as pressure waves or P waves), secondary waves (also known as shear waves or S waves), Love waves (also known as Q waves or L waves), and Rayleigh waves (also known as R waves). The P waves are the fastest waves generated by an earthquake, and are generally non-destructive. In one embodiment, the presence of P waves, sensed by the earthquake sensor 302, is an earthquake condition 312. The earthquake sensor 302 senses the P waves and generates the earthquake condition message 320 in response. It is typical that such an embodiment would provide approximately one second of warning time for every five miles of distance between the earthquake sensor 302 and the epicenter of the earthquake.
The earthquake sensor 302 may include a seismometer for measuring the motion of the ground such that the earthquake sensor 302 can detect earthquakes. The seismometer may use electronic sensors and be configured to measure motions over a wide range of frequencies. The earthquake sensor 302 may, in one embodiment, measure motion with frequencies of between 0.001 Hz and 500 Hz. The seismometer may include a small mass that is maintained substantially stationary by electrical forces. The amount of force necessary to maintain the mass in a substantially stationary position is then used to determine information about the seismic event. The earthquake sensor 302 may include a geophone, a broadband seismograph, an accelerograph, or other suitable device for detecting seismic events.
In certain embodiments, the earthquake sensor 302 and/or the earthquake response module 200 may be configured to filter out smaller earthquakes such that no alarm is generated in response. For example, the earthquake sensor 302 may be configured to send the earthquake condition message 320 only in response to an earthquake of a magnitude of approximately 4.0 on the Richter scale. Such an approach may prevent an alarm from sounding for earthquakes that are unlikely to cause damage or to require action on the part of people in the facility associated with the earthquake sensor 302.
The earthquake response module 200, in response to receiving the earthquake condition message 320, may cause the alarm module 113 to generate an alarm. The alarm module 113 may generate an alarm with an audio component. For example, the alarm may include an audible beep or siren. The alarm may provide audible instructions or other verbal warning; for example, the alarm may state that an earthquake is imminent and instruct users to seek cover. The alarm may also have a visual component. For example, the alarm may include flashing lights, a message displayed on a display panel for the control unit 102, a message on a television in communication with the alarm module 113, or other suitable visual alert.
The system 300 may also include a remote earthquake module 330. The remote earthquake module 330 may, in one embodiment, be implemented as part of the monitoring system 103. The monitoring system 103 may connect to the control unit 102 through one or more networks; for example, the control unit 102 and the monitoring system 103 may be connected through the Internet, a wireless cellular network, or other type of network. In one embodiment, the monitoring system 103 and the control unit 102 may be connected through more than one network; such an implementation may provide additional redundancy and help guard against network failure and network congestion.
The remote earthquake module 330 may be software executing on a remote server in communication with the control unit 102. In certain embodiments, the earthquake response module 200 is configured to send an earthquake condition notification 322 to the remote earthquake module 330. An earthquake condition notification 322 refers to a communication indicating the occurrence of an earthquake condition 312 detected by an earthquake sensor 302. In certain embodiments, the earthquake condition message 320 and the earthquake condition notification 322 contain the same substantive information. The formatting and content of the earthquake condition notification 322 may be different in order to account for different protocols. For example, the earthquake sensor 302 may send the earthquake condition message 320 using the Z-Wave wireless communications protocol. The control unit 102 may send the earthquake condition notification 322 using the hypertext transfer protocol (HTTP), and may include additional and/or different information than the earthquake condition message 320.
In one embodiment, the earthquake condition message 320 sent by the earthquake sensor 302 includes one or more readings by the earthquake sensor 302 that caused the earthquake sensor 302 to determine that an earthquake condition 312 had occurred. The earthquake condition message 320 sent by the earthquake sensor 302 may also include additional information, such as the times at which the readings were made. The control unit 102 may add additional information to the earthquake condition notification 322 sent to the remote earthquake module 330. For example, the control unit 102 may provide an identifier that uniquely identifies the control unit 102, location information that identifies the location of the control unit 102 (such as geographic information system (GIS) data), and other information in addition to the readings by the earthquake sensor 302.
In certain embodiments, the earthquake response module 200 may be configured to also send the earthquake condition notification 322 to one or more mobile devices. For example, the earthquake response module 200 may send an earthquake condition notification 322 to one or more cellular phones or other devices registered with the control unit 102. The earthquake response module 200 may send an earthquake condition notification 322 to any device registered with the remote activation system 131 shown in
Similarly, alerts to mobile devices (whether for an earthquake or a tsunami) may be valuable for remote individuals even if the alert is not received prior to the event. An individual responsible for a particular facility may want to be aware of a significant event such as an earthquake or tsunami immediately before or after. For example, a manager for a company with a large data center may want to be alerted to earthquakes, and related events, at the data center facility even if the manager is situated in another part of the country.
The earthquake sensor 302 may detect an earthquake condition 312 and send an earthquake condition message 320 to the control unit 102, as described above in connection with
The remote earthquake module 330 may be configured to generate one or more earthquake alert messages 410 that are sent from the monitoring system 103 to one or more control units (such as control unit 402) that are separate from the control unit (in
The remote earthquake module 330 may further implement a model to predict the scope and character of the earthquake based on the earthquake condition notifications 322 received from multiple control units. The model may determine which control units 102 receive earthquake alert messages 410. The model may account for the geographic conditions of the areas where the control units are located. For example, the model may take into account the locations of faults, historic patterns of seismic activity in a particular area, and other factors. In this manner, the remote earthquake module 330 may make intelligent predictions about an anticipated size and scope of an earthquake detected by one or more earthquake sensors providing seismic information to the remote earthquake module 330, and provide an earthquake alert message to all control units within a geographic area that the model predicts will be affected by the earthquake.
In certain embodiments, the remote earthquake module 330 may be further configured to communicate with a public earthquake early warning system. A public earthquake early warning system generally makes use of a system of seismic motion sensors arranged throughout a particular region and use high-speed communications systems to collect readings from those motion sensors. The public earthquake early warning system may also include one or more computers that estimate the size, scope, and/or progression of an earthquake, as well as such local factors as the type of soil in the area. Based on such calculations, the public earthquake early warning system may send warnings to people in the anticipated affected areas. For example, the public earthquake warning system may send warnings using television, radio, mobile devices, and other appropriate devices to communicate with users.
The remote earthquake module 330 may receive warnings from the public earthquake early warning system and send earthquake alert messages to control units (such as control units 402 and 102) in communication with the monitoring system 103. The control units 402 and 102 that receive such an earthquake alert message may generate an alarm to warn persons at the facility as described above. In other embodiments, the control units are configured to receive the warnings from the public earthquake early warning system directly from the public earthquake early warning systems itself.
In certain embodiments, the public earthquake early warning system sends warnings about the earthquake event itself; in other embodiments, the public earthquake early warning system also sends warnings about earthquake-related events. For example, the public earthquake early warning system may send a warning of a possible tsunami. In certain situations, the earthquake itself may pose little risk while the tsunami it causes poses a large risk. In such embodiments, the control units may thus receive and warn of an incoming tsunami.
In certain areas where tsunamis are a risk, the earthquake response module 200 may be configured to behave differently than an earthquake response module 200 in an area where a tsunami is not a risk. For example, the earthquake response module 200 may be configured to provide a warning even for those earthquakes that are too far away to pose a serious threat to the facility if the earthquake occurred in a location, and with sufficient magnitude, that a tsunami is a risk.
The remote earthquake module 330 may be further configured to send data derived from earthquake condition notifications 322 to the public earthquake early warning system. The public earthquake early warning system may use such data in order to further refine the predictions of the affected area and other information related to the earthquake.
In certain embodiments, the nature of the alarm may vary based on the entity communicating with the control unit 402. In one embodiment, the earthquake response module 402 generates a first message indicating that the warning has been generated based on measurements of the earthquake sensor 404 if an earthquake condition message 450 is received. A second message may be provided if the earthquake response module 402 receives an earthquake alert message 410 due to a warning provided by a public earthquake early warning system. For example, the second message may state “Your public earthquake early warning system is providing an earthquake warning. Please prepare for a powerful earthquake.”
The earthquake sensor 404 may be configured to provide the earthquake condition message 450 when the earthquake condition 312 is detected even if an earthquake alert message 410 has already been received by the control unit 402. The earthquake response module 402 may still send an earthquake condition notification to the remote earthquake module 330 even if the earthquake response module 402 has already received the earthquake alert message 410. Such an embodiment may allow the remote earthquake module 330 to gather additional data about the earthquake. For example, if the remote earthquake module 330 generates an earthquake alert message 410 based on an earthquake condition notification 322, but the earthquake sensor 404 never reports an earthquake condition 312, the earthquake alert message 410 may have been a false alert. Configuring the earthquake response module 402 in the manner described above may help the remote earthquake module 330 detect false alarms. The model used by the remote earthquake module 330 may be further refined in order to reduce the likelihood of future false alerts.
Similarly, the remote earthquake module 330 may be able to gather information about the earthquake in real time from the various earthquake sensors deployed throughout the system 400 and dynamically predict the strength and direction of the earthquake and adjust which control units are to be sent earthquake alert messages 410 appropriately. The remote earthquake module 330 may further be configured to provide the data received in the earthquake condition notifications 322 to the public earthquake early warning system. Sharing this data may further benefit the community by providing data that may be helpful in refining earthquake models and the public earthquake early warning system. Such an embodiment may also allow the individual earthquake sensors in various facilities to act as an extension of the public earthquake early warning system to the benefit of the community as a whole.
The control units 502, 512, and 522 may be associated with separate security systems installed at separate facilities. In one embodiment, the control units 502, 512, and 522 are installed at unrelated facilities; for example, each of the control units 502, 512, and 522 may be for a separate residence within a geographic area.
In the embodiment shown in
In one embodiment, each control unit in the system 500 is associated with a unique address. The control units in the system 500 may be configured to send an earthquake alert message directly to one or more of the control units within the system 500. For example, in
In one embodiment, the control unit 502 is configured to send an earthquake condition message 502 to all other control units within a specified range of the control unit 502. The control unit 502 may, for example, send an earthquake alert message 520 to all control units within three miles of the control unit 502. In one embodiment, the control units (such as control unit 516) that receive the earthquake alert message 520 send an earthquake alert message 504 to other control units (such as control unit 522). The control unit 512 may be configured to send the earthquake alert message 504 only when the earthquake sensor 518 also detects the earthquake condition 530. Such an embodiment may prevent the earthquake alert message 520 from being passed to those control units that are too far from the earthquake condition 530 to feel the effects of the earthquake.
The earthquake response module 506 may generate and send the earthquake alert message 520 to the earthquake response module 516 of the control unit 512. The earthquake response module 516 may send the earthquake alert message 504 to the earthquake response module 526 of the control unit 522. In certain embodiments, the earthquake alert message 520 contains information about the earthquake condition 530 and the control unit 502. For example, the earthquake alert message 520 may contain data indicating the strength of the earthquake condition 530 and an identifier for the control unit 502. The earthquake response module 516 may be configured to determine the distance between the control unit 512 and the control unit 502. Based on the distance and the strength of the earthquake condition 530, the earthquake response module 516 may determine whether to send the earthquake alert message 504 to the control unit 522 before the earthquake condition 530 is independently detected by the earthquake sensor 518 associated with the control unit 512. For example, if the distance is less than two miles, and the earthquake alert message 520 indicates an intense earthquake, the earthquake response module 516 may send the earthquake alert message 504 without awaiting confirmation by the earthquake sensor 518.
The earthquake response module 526 may similarly examine the earthquake alert message 504. The earthquake response module 526 may determine, for example, that the distance between the control unit 522 and the earthquake sensor 508 that detected the earthquake condition 530 is ten miles. The earthquake response module 526 may determine, based on the distance separating the control unit 522 and the earthquake sensor 508, not to send a further earthquake alert message to another control unit at that time.
When the earthquake sensor 518 detects the earthquake condition 530, it may send a second earthquake alert message to the control unit 522. This second earthquake alert message may include data about the intensity of the earthquake condition 530 as measured by the earthquake sensor 518. The control unit 522 may then re-evaluate whether to send an earthquake alert message to other control units.
Similarly, the earthquake sensors may provide additional earthquake condition messages providing additional information as the earthquake event unfolds. For example, the earthquake sensor 508 may send the earthquake condition message 540 when it detects P waves. A second earthquake condition message may be sent when the earthquake sensor 508 senses the S waves. Additional earthquake condition messages may be sent describing the L waves and/or the R waves. The control unit 502 may send additional earthquake alert messages containing this additional information to other control units and/or the remote earthquake module 330 discussed in
In certain embodiments, the system 500 and the system 400 may be combined such that control units are communicatively coupled with one or more additional control units, as described in
The control units may be configured to send earthquake alert messages (directly and/or indirectly) to all control units within a given geographic region in response to any one control unit detecting an earthquake condition 530. For example, all control units along a fault line may be configured to send earthquake alert messages to other control units along the fault line.
For example, in
The control units may have rules for determining whether to send an earthquake alert message in response to receiving an earthquake alert message from another control unit. For example, the control unit 608 may be configured to send an earthquake alert message to only the control unit 616 in response to receiving an earthquake alert message from the control unit 602 since the control unit 608 may assume that the control unit 606 was alerted by the control unit 602, and that the control unit 602 (which detected the earthquake condition) does not require an earthquake alert message. Other rules for providing an appropriate flow of earthquake alert messages through the network 600 may also be implemented.
The control units 602-626 may each implement network modules as shown in
The method may also include, at reference numeral 706, monitoring a remote server implementing a remote earthquake module for earthquake alert messages. The remote earthquake module may generate the earthquake alert message if a control unit sends the remote earthquake module an earthquake condition notification as discussed in connection with
The method may include, at reference numeral 708, generating an audible alarm in response to receiving the earthquake condition message from the earthquake sensor. In one embodiment, a control unit may receive the earthquake condition message and generates the audible alarm that includes a verbal warning and instructions in anticipation of the earthquake. The control unit may also provide a visual alarm, such as flashing lights, in response to receiving the earthquake condition message. The method may also involve generating an audible alarm in response to receiving an earthquake alert message from the remote earthquake module or from another control unit that is in communication with the control unit implementing the method.
The method may further involve, at reference numeral 710, sending an earthquake condition notification to the remote server implementing the remote earthquake module. The method may also involve, at reference numeral 712, sending an earthquake alert message to a separate control unit over a network of control units, as described in connection with
While the foregoing disclosure sets forth various embodiments using specific block diagrams, flowcharts, and examples, each block diagram component, flowchart step, operation, and/or component described and/or illustrated herein may be implemented, individually and/or collectively, using a wide range of hardware, software, or firmware (or any combination thereof) configurations. In addition, any disclosure of components contained within other components should be considered exemplary in nature since many other architectures can be implemented to achieve the same functionality.
