The disclosure generally relates to hazardous condition detectors, and more particularly relates a portable fire alarm device for unconditional spaces and a method of operation thereof.
Fire alarm systems are safety devices designed to detect smoke, heat, or flames and alert occupants of a potential fire hazard. The fire alarm systems typically consist of smoke detectors, heat sensors, alarms, and control panels, enabling timely response to prevent loss of life and property. Currently, there are various fire alarm systems that are good solutions for fire detection in conditional spaces like a house or an office. However, such fire alarm systems fail to effectively detect a potential fire hazard in unconditional spaces like garages, remote storage sheds with battery-based devices, covered electric vehicle charging stations, workshops with battery-based devices, remote manufacturing facilities with battery-based devices, and/or any other covered space including battery-based devices, where factors like dust, pollution, and space impact the accuracy of such fire alarm systems. For instance, the surge in Electric Vehicles (EVs) adoption in sustainable transportation, has also brought about a new concern regarding fire hazards within confined spaces, such as garages used to park the EVs. The substantial energy stored in EV batteries (for example, Lithium Ion (Li-Ions) batteries) makes the EV batteries susceptible to overheating, especially in such confined spaces.
Further, the conventional fire alarm systems are complex and require extensive human efforts in installation and maintenance. Also, the conventional fire alarm systems are based on a limited number of sensors, majorly based on temperature sensors neglecting the other possible scenarios that can lead to potential fire hazards. Furthermore, the installation costs of the conventional fire alarm systems tend to be high due to factors, such as their size, design, and power requirements. Also, the power management within the conventional fire alarm systems is suboptimal.
Additionally, due to complex structure and high power requirements at the conventional fire alarm systems, it is difficult to install and/or relocate the fire alarm systems.
Therefore, in view of the above-mentioned problems, there is a need to provide an improved fire alarm system.
This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the disclosure. This summary is neither intended to identify key or essential inventive concepts of the disclosure and nor is it intended for determining the scope of the disclosure.

Embodiments of the disclosure will be described below in detail with reference to the accompanying drawings.
The device 100 may correspond to a compact and easily transportable device designed to detect a presence of fire or smoke and generate alerts to warn individuals of potential fire danger. The device 100 may generate alarms that are intended to provide timely notifications in various settings, promoting rapid evacuation and response to fire emergencies. The device 100 may be a light-weight device that has a small form factor. Further, the device 100 may support a variety of layouts and/or configurations to be suitably installed at different deployment sites. For instance, the device 100 may be installed over a vehicle, a ceiling of a garage/building, a door lock of a garage/building, a door of the garage/building, and so forth.
The sensing unit 102 of the device 100 may be configured to receive a plurality of signals from one or more sensors. The one or more sensors include, but are not limited to, one or more on-board sensors 104 and one or more remotely located sensor devices 116 (interchangeably referred to as “the remote sensor devices 116”). Examples of the one or more sensors include, but are not limited to, temperature sensors, gas sensors, smoke sensors, and flame sensors. The temperature sensors may be configured to determine a value of temperature in the environment. The temperature sensors are configured to monitor and measure changes in temperature within the environment. Based on different types of technologies used in such temperature sensors, the temperature sensors may be classified as thermal detectors, thermocouples, Resistance Temperature Detectors (RTDs), infrared temperature sensors, and so forth. A temperature sensor is configured to generate an output signal corresponding to the change in temperature when the temperature of the environment rises beyond a specific threshold or at a rapid rate. The smoke sensors, which may also be referred to as the smoke detectors, are devices that are configured to detect the presence of smoke in the environment. The smoke detectors are configured to sense particulate matter and/or aerosols produced by combustion process to identify an initial sign of fire. The smoke detectors may be based on various technologies such as, but not limited to, ionization methods, photoelectric methods, or a combination thereof. The smoke detectors are configured to generate an output signal in response to detection of smoke in the environment. The gas sensors are configured to detect the presence of potentially hazardous gases in the environment, specifically gases that indicate a fire or other hazardous situation. The gas sensors for fire alarms are designed to detect gases such as, but not limited to, Carbon Monoxide (CO), Carbon Dioxide (CO2), methane (CH4), hydrogen (H2), Hydrogen Fluoride (HF), and so forth. When a gas sensor detects the presence of a target gas, the gas sensor generates an output signal corresponding to said detection of the target gas. The flame sensors detect the presence of flames or fires by sensing specific wavelengths of light emitted by flames. The flame sensors operate based on optical sensing technologies and are designed to differentiate between unique characteristics of light emitted by flames and other sources of light, such as sunlight or artificial lighting. Based on the above, a flame sensor generates an output signal corresponding to the detection of flame in the environment.
In one embodiment, the temperature sensors, the gas sensors, the smoke sensors, and the flame sensors discussed above may be implemented as the one or more on-board sensors 104. Further, the one or more remote sensor devices 116 may also include the temperature sensors, the gas sensors, the smoke sensors, and the flame sensors. The one or more on-board sensors 104 may be located within a housing of the device 100. The one or more on-board sensors 104 may be integrated with other components of the device 100. The one or more remote sensor devices 116 may be located remotely to the device 100. Non-limiting examples of different locations of the one or more remote sensor devices 116 may be a battery source of a vehicle, a fuel tank of a vehicle, a ceiling of a garage, and/or near to any flammable object/substance. Embodiments are exemplary in nature, and the one or more on-board sensors 104 or the one or more remote sensor devices 116 may correspond to any suitable sensing device configured to detect fire, smoke, or gases. The sensing unit 102 may be configured to receive the various output signals from each of the above-mentioned sensors to generate sensor-related data corresponding to an environment. The sensor-related data may indicate information such as, but not limited to, a change in temperature, a detection of flame, a detection of a target gas, and/or a detection of smoke in the environment.
The processing unit 106 may be communicably coupled with the sensing unit 102. The processing unit 106 may include specialized processing units such as, but not limited to, integrated system (bus) controllers, memory management control units, floating point units, digital signal processing units, etc. In one embodiment, the processing unit 106 may include a central processing unit (CPU), a Graphics Processing Unit (GPU), or both. The processing unit 106 may be one or more general processors, Digital Signal Processors (DSPs), Application-Specific Integrated Circuits (ASIC), Field-Programmable Gate Arrays (FPGA), servers, networks, digital circuits, analog circuits, combinations thereof, or other now known or later developed devices for analyzing and processing data. In an embodiment, the processing unit 106 may execute a software program, such as code generated manually (i.e., programmed) to perform the desired operation.
The processing unit 106 may be configured to receive the sensor-related data indicating the at least one of the change in the temperature, the detection of flame, the detection of the target gas, or the detection of smoke in the environment, from the sensing unit 102. The processing unit 106 may further be configured to compare the at least one of the change in the temperature, the detection of flame, the detection of the target gas, or the detection of smoke in the environment with corresponding predefined criteria to determine whether the received sensor-data corresponds to a potential fire hazard. The processing unit 106 may be configured to eliminate a chance of false positives by effectively utilizing the sensor-related data generated based on the signals from multiple sensors. The processing unit 106 may validate signals from multiple sensors before utilizing such signals for determination of potential fire hazard. In some embodiments, the processing unit 106 may utilize sensor-related data from at least two sensors to reduce the chances of false positive. For example, the processing unit 106 may compare temperature change against predetermined threshold (e.g. 40 F) designated as primary alarm criterion with change in signal from gas/particulate/smoke sensors (e.g. 10% change against baseline) to confirm whether alarm is due to fire, or it is a false positive. Alternatively, the reverse strategy may be employed where a gas/particulate/smoke sensor signal is monitored as the primary alarm criterion with the change in temperature used to confirm the event as fire or a false positive. Analogously, rather than using change of signal as the appropriate alert criterion, the rate of change of signal in time may be used instead. For example, if the temperature rises 40 F in 10 minutes this may be classified as a false positive, but if that same 40 F rise occurs in 1 minute it may be signifying fire event.
The device 100 includes the alert generation unit 108 that is communicably coupled to the processing unit 106. The alert generation unit 108 may be configured to generate an alert based on the sensor-related data corresponding to the environment. Examples of alerts generated by the alert generation unit 108 may include, but are not limited to, an activation of one or more visual indicators, an activation of a sound signal, or a combination thereof. In some embodiments, the alert generation unit 108 may also be configured to generate sensory alerts to notify the individuals/users within the environment or associated with the device 100, about the potential fire hazard. In an embodiment, the alert generation unit 108 may generate alarm signals such as, but not limited to, sirens, bells, horns, recorded voice messages or other loud audible sounds, to notify the users about the potential fire hazard. In another embodiment, the alert generation unit 108 may generate visible alarm signals such as, but not limited to, bright strobe lights, flashing lights, or other visual indicators that provide a visual indication to the users about the potential fire hazard. The alert generation unit 108 may include and/or be coupled to any suitable device such as, audio speaker, Light Emitting Diodes (LEDs), etc., to generate the above-mentioned alarm signals.
The interface module 110 may be communicably coupled to the processing unit 106 and/or the alert generation unit 108. In an exemplary embodiment, the interface module 110 may be configured to establish a connection with a communication module of another device 118 to send the generated alert to one or more external electronic devices 121. Further, the another device 118 may include, but not limited to, a smart lock device, an Internet of Thing (IoT) home device, or an external alarm system. Examples of the external electronic devices 121 may include, but are not limited to, smartphones, tablets, laptops, personal computers, server computers, building management systems, building security systems, and so forth. The interface module 110 may include a connection port to establish a connection with a communication module of the another device 118 and/or the one or more external electronic devices 121. The interface module 110 may connect to the another device 118 and/or the one or more external electronic devices 121 via any suitable connection means such as, a wired connection and/or a wireless connection. Thus, the alarm may be further relayed through another device containing means of amplifying and furthering the fire warning signal as appropriate. For example, relaying fire signal to a thermostat in a home would allow that thermostat to emit beeping sounds if equipped with a speaker and/or flash a warning message if equipped with a display screen and/or flash a light if equipped with an LED light or other illumination light. Analogously, the alarm signal may be relayed to a smart home device that may initiate a mitigation action in response to the fire alarm. For example, alarm signal at a smart lock could be pre-programmed to open the door facilitating easier egress from the residence. Similarly, alarm signal arriving at an automatic/smart garage opener could be used to open the garage doors to facilitate egress and alert passers by of the fire event.
In some embodiments, the interface module 110 may include interfaces that may employ communication techniques such as, but not limited to, code-division multiple access (CDMA), high-speed packet access (HSPA+), global system for mobile communications (GSM), long-term evolution (LTE), WiMax, etc. In an embodiment, the interface module 110 may include a network interface to employ connection protocols including, without limitation, direct connect, Ethernet (e.g., twisted pair 10/100/1000 Base T), transmission control protocol/internet protocol (TCP/IP), token ring, IEEE 802.11a/b/g/n/x, etc. In some embodiments, the interface module 110 may be communicably coupled with the one or more external devices 121 via a communication network that may include, without limitation, a direct interconnection, local area network (LAN), wide area network (WAN), wireless network (e.g., using Wireless Application Protocol), the Internet, etc.
The power unit 111 may be configured to supply power to the sensing unit 102, the processing unit 106, the alert generation unit 108, and/or the interface module 110 via an Alternating Current (AC) power supply 120, an external Direct Current (DC) power source 122, or a DC power source 115 (also referred to as the internal DC power source 115).

In a non-limiting example, the external DC power source 122 may include a battery powered device. Moreover, the power unit 111 may include the DC power source 115 to supply power to the sensing unit 102, the processing unit 106, the alert generation unit 108, and/or the interface module 110 to generate the alert.

Further, the device 100 may include a memory (not shown) configured to store data and/or instructions for the processing unit 106 and/or the alert generation unit 108 to perform the desired functions of the device 100. The memory may include, but is not limited to, a non-transitory computer-readable storage media, such as various types of volatile and non-volatile storage media including, but not limited to, random access memory, read-only memory, programmable read-only memory, electrically programmable read-only memory, electrically erasable read-only memory, flash memory, magnetic tape or disk, optical media and the like.
