<CIT> discloses a detector system which includes an active unit, such as a detector unit, which has a processor, a network port for connection to a central control unit, and an optical data input port. The processor is arranged to enable the optical data input port on receipt of an enable signal received by the active unit from the central control unit via a network.

The present invention is defined in the independent claims, to which reference should now be made. Optional features are defined in the dependent claims.

The components illustrated in the figures represent components that may or may not be present in various embodiments of the present disclosure described herein such that embodiments may include fewer or more components than those shown in the figures while not departing from the scope of the present disclosure. Some components may be omitted from one or more figures or shown in dashed line for visibility of the underlying components.

The phrases "in an example embodiment," "some embodiments," "various embodiments," and the like generally mean that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure, and may be included in more than one embodiment of the present disclosure (importantly, such phrases do not necessarily refer to the same embodiment).

If the specification states a component or feature "can," "could," "should," "would," "preferably," "possibly," "typically," "optionally," "for example," "often," or "might" (or other such language) be included or have a characteristic, that a specific component or feature is not required to be included or to have the characteristic. Such components or features may be optionally included in some embodiments, or may be excluded.

The terms "electronically coupled" or "in electronic communication with" in the present disclosure refer to two or more electrical elements (for example, but not limited to, an example processing circuitry, communication module, input/output module, memory, flame detecting component) and/or electric circuit(s) being connected through wired means (for example but not limited to, conductive wires or traces) and/or wireless means (for example but not limited to, wireless network, electromagnetic field), such that data and/or information (for example, electronic indications, signals) may be transmitted to and/or received from the electrical elements and/or electric circuit(s) that are electronically coupled.

The term "electromagnetic radiation" or "radiation" may refer to various kinds of electromagnetic radiant energy that exhibits properties of waves and particles including visible light, radio waves, microwaves, infrared (IR), ultraviolet (UV), X-rays and gamma rays. Visible light may refer to electromagnetic radiation that can be detected by a human eye. The electromagnetic spectrum comprises a range of all known types of electromagnetic radiation, including electromagnetic radiation that cannot be detected by the human eye. Various portions of the electromagnetic spectrum are associated with electromagnetic radiation that has certain characteristics (e.g., certain wavelengths and frequencies). For example, visible light emits electromagnetic radiation with wavelengths ranging between <NUM> and <NUM> nanometers (nm). In contrast, IR electromagnetic radiation may comprise wavelengths ranging between <NUM> and <NUM> microns.

A fire source produces electromagnetic radiation with certain characteristics. For example, flames associated with a fire source may emit electromagnetic radiation with particular IR, visible light and UV characteristics/properties (e.g., wavelengths, frequencies, and/or the like). These characteristics and properties may depend on characteristics of the fire source (e.g., fuel type). By way of example, flames generated by a hydrocarbon fuel source may emit IR radiation with a frequency between <NUM> microns and <NUM> microns and a UV signal with a frequency of <NUM> microns. While the visible light radiation produced by a fire can be perceived visually (e.g., as red and yellow flames), the IR and UV radiation cannot be detected by the human eye.

Flame detection apparatuses are configured to monitor a field of view and generate alerts or alarms and/or activate a fire suppression system based on detected environmental conditions. An example flame detection apparatus are configured to detect radiation (e.g., visible light, UV and/or IR), smoke, temperature, combinations thereof, and/or the like within an environment. In some embodiments, flame detection apparatuses may be required and/or installed in environments where there is a high likelihood of a fire and/or where certain types of combustible materials are utilized or stored. For example, flame detection apparatuses may be required at power plants, chemical storage and production facilities, hydrocarbon facilities or the like.

In general, a flame detection apparatus comprises at least one flame detecting component for detecting radiation (e.g., flames) within a field of view of the flame detection apparatus. An example field of view may be or define a coverage area, range and/or angle of view in a vicinity of the flame detection apparatus. In various embodiments, the field of view of a flame detection apparatus may be manually and/or programmatically adjustable. For example, the field of view may be manually adjustable by directing (e.g., pointing) the flame detecting component in a direction of a likely source of fire within an environment. Additionally and/or alternatively, the field of view may be a programmatically selected distance or range (e.g., <NUM> meters, <NUM> meters, <NUM> meters or <NUM> meters). The example flame detection apparatus may be configured to identify radiation characteristics (e.g., a modulation rate or flicker rate) associated with a fire source. The flame detection apparatus may store information (e.g., algorithms) such that it can process received information in order to identify radiation associated with fire sources. An example flame detecting component may be or comprise an optical component, for example, without limitation, an IR sensor, UV sensor, and/or the like. In some embodiments, the flame detection apparatus may comprise combinations of flame detecting components. An example flame detection apparatus may comprise a UV sensor and an IR sensor. Another example flame detection apparatus may comprise a plurality of IR sensors (e.g., multispectrum IR sensors). In response to detecting radiation with particular characteristics (i.e., indicating the presence of flames) within the field of view, a flame detection apparatus may trigger activating an alarm/alert and/or a fire suppression system.

In various embodiments, a flame detection apparatus may periodically require service, testing and/or recalibration after being installed in the field. For example, the flame detection apparatus may require periodic (e.g., semi-annual, annual) testing in order to satisfy safety regulations. Additionally, the performance of a flame detection apparatus may be affected by dirt and debris incident on flame detecting components. In some cases, one or more components of a flame detection apparatus may malfunction such that the flame detection apparatus will not be able to detect radiation and may in some cases fail to trigger an alert. In order to ensure proper functioning in high-risk environments, it is therefore necessary that a flame detection apparatus can routinely provide operational status information and also be periodically tested and/or updated. By way of example, a flame detecting component may require replacement/cleaning, a power source (e.g., battery) may need to be replaced or the like. Although some existing flame detection apparatuses may be configured to communicate status information via indication elements (e.g., light emitting diodes (LEDs)), detected faults and issues may not be readily apparent particularly in an instance in which the flame detection apparatus is located out of reach such that a wired connection cannot easily be established. Accordingly, it may be necessary to completely remove the flame detection apparatus in order to properly diagnose and remediate any exiting faults. In another example, if there is more that one fault present, indication elements may indicate a fault condition without actually specifying the types or faults.

In some embodiments, it may be necessary to modify flame detection apparatus configuration settings in response to environmental changes and/or changes in safety requirements associated with an environment. For instance, a flame detection apparatus may require reconfiguration in response to environmental modifications. By way of example, in a hydrocarbon storage environment, relocation of a storage tank may necessitate physical relocation and/or programmatic reconfiguration of a flame detection apparatus in an area corresponding with the location of the storage tank. In another example, a flame detection apparatus may need to be reconfigured in an instance in which changes to an associated fire detection system have been made (e.g., removal or addition of new apparatuses). Additionally and/or alternatively, operational parameters (e.g., sensitivity) of a flame detecting component may need to be adjusted based at least in part on characteristics of the potential fire sources (e.g., fuel types) in an environment. Accordingly, if a fuel type present within an environment is removed or replaced, the operational parameters of one or more flame detecting components may also need to be modified.

In general, flame detection apparatuses may be configured in the field using wired communication protocols such as Modbus, HART, RS485 and/or the like which require a cable to provide a communication channel between the flame detection apparatus and a specialized control device. Additionally, end users are often unable to operate such control devices and may require a skilled technician in order to make even minor changes to configuration settings. As noted above, existing flame detection apparatuses are not configured to wirelessly receive and transmit data/information and typically have no wireless functionalities such as Wi-Fi, Bluetooth, ZigBee or the like. Wireless functionalities are generally foregone due to technical challenges such as design limitations and difficulty meeting various safety and certification standards when such wireless functionalities are introduced. In some cases, for security reasons, regulations do no permit wireless functionality for flame detection apparatuses due to safety concerns. Additionally, incorporating wireless functionalities in flame detection apparatuses increases overall production costs and production complexity.

In accordance with various embodiments of the present disclosure, example methods, apparatuses and systems are provided.

In various embodiments, the present disclosure may provide an apparatus comprising a controller component and at least one flame detecting component. The at least one flame detecting component is configured to detect infrared radiation associated with a fire in an environment and receive and transmit communication signals.

Additionally, the flame detecting component <NUM> may be configured to receive and transmit communication signals (e.g., IR control signals). An example flame detecting component <NUM> may be or comprise an optical-based sensing component, for example, without limitation, a photodiode, a photosensor, an IR sensor, a UV sensor, and/or the like. In various embodiments, the flame detecting component <NUM> may include a light filter and/or lens to restrict the frequency of radiation receivable by the flame detecting component <NUM>. As noted above, a flame detecting component <NUM> may be associated with a particular field of view based at least in part on the location of the flame detection apparatus <NUM>, the positioning of the flame detecting component <NUM>, and/or flame detection apparatus configuration settings. As such, a flame detection apparatus <NUM> field of view can by modified by physically changing the location of the flame detection apparatus <NUM> and/or pointing the flame detecting component in a particular direction. Additionally, the flame detection apparatus <NUM> field of view may also be programmatically adjusted by changing one or more flame detection apparatus <NUM> configuration settings. For example, the flame detecting component <NUM> of a flame detection apparatus <NUM> may be programmatically configured to operate up to a certain distance from the flame detecting component <NUM> (e.g., up to <NUM> meters, <NUM> meters, <NUM> meters or <NUM> meters) corresponding with characteristics of the potential fire source (e.g., a location and/or fuel type).

In various embodiments, the information/pulses provided by the flame detection apparatus <NUM> may describe information regarding a condition or status of the flame detection apparatus <NUM>. For example, the information/pulses may describe a battery status, a fire detecting component operational status, other current settings associated with the flame detection apparatus <NUM>, and/or the like. Additionally and/or alternatively the IR control signals generated and transmitted and by the flame detection apparatus may contain information (e.g., messages) indicating whether or not received configuration instructions were successfully executed. In some embodiments, the flame detection apparatus <NUM> may cause generation of an IR control signal in order to provide information in response to a request for information received from the IR configurator apparatus <NUM>. In other examples, the flame detection apparatus <NUM> may automatically generate an IR control signal in order to transmit information in response to detected conditions that satisfy one or more stored parameters.

In some examples, the flame detection apparatus may execute the instruction/command and generate an IR control signal comprising a message acknowledging that the flame detection apparatus is in testing mode. In some examples, subsequent to receiving a control signal comprising the acknowledgement from the flame detection apparatus, the IR configurator may transmit a control signal comprising a message (e.g., instruction or command) to test a system component (e.g., relay outputs). In some examples, subsequent to receiving the command, the flame detection apparatus may execute the instruction/command and generate a control signal comprising a message describing the results of the executed testing. In some examples, subsequent to receiving the control signal comprising the results of the executed testing, the IR configurator apparatus may generate a control signal comprising a message (e.g., instruction or command) for the flame detection apparatus to come out of testing mode and resume normal operations.

The example method <NUM> begins with step/operation <NUM>. At step/operation <NUM>, a processing circuitry (such as, but not limited to, the processing circuity of IR configurator apparatus <NUM> illustrated above in regard to <FIG>) causes generation of a first IR control signal, for example, by a IR source element of the IR configurator apparatus. As noted above, the IR control signal may comprise a carrier signal containing information/messages (e.g., pulses). The pulses may describe a request for status information, configuration instructions and/or the like. The IR configurator apparatus may be caused to generate the IR control signal in response to a user actuating or selecting an input/output element (e.g., buttons, a display element/circuitry and/or the like) of the IR configurator apparatus. The IR configurator apparatus may comprise a plurality of input/output elements, each corresponding with information and/or actions in accordance with the stored communication protocol. By way of example, a first button may be selected to request status information from a flame detection apparatus and a second button may be selected to cause transmission of a particular set of instructions to the flame detection apparatus. In some embodiments, the IR configurator apparatus may display information received from the flame detection apparatus via the display element/circuitry. As noted, in some embodiments, the IR configurator apparatus may be configured to encode information prior to generating the first IR control signal such that secured encoded information (e.g., messages) is provided to the flame detection apparatus.

Subsequent to step/operation <NUM>, the example method <NUM> proceeds to step/operation <NUM>. At step/operation <NUM>, the processing circuitry receives an indication of a second IR control signal. In various embodiments, the second IR control signal may be detected by an IR transceiver of the IR configurator apparatus. The second IR control signal may be generated by a flame detecting component of a flame detection apparatus in electronic communication with the IR configurator apparatus. The second IR control signal may similarly comprise a carrier signal containing information/messages (e.g., pulses). The pulses may describe requested status information, confirmation of executed instructions and/or the like. As noted, in some embodiments, the IR configurator apparatus may be configured to decode information received from the flame detection apparatus (e.g., using stored encryption information/keys) in order to ensure communication security.

Referring now to <FIG>, in some examples, the method <NUM> may be performed by a processing circuitry (for example, but not limited to, an application-specific integrated circuit (ASIC), a central processing unit (CPU)). In some examples, the processing circuitry may be electrically coupled to and/or in electronic communication with other circuitries of the example apparatus, such as, but not limited to, a flame detecting component, an indication element, a IR source element, a memory (such as, for example, random access memory (RAM) for storing computer program instructions), and/or a display circuitry (for rendering information on a display).

The example method <NUM> begins at step/operation <NUM>. At step/operation <NUM>, a processing circuitry (such as, but not limited to, the processing circuitry <NUM> of the controller component <NUM> illustrated in connection with <FIG>, discussed above) receives an indication of the first IR control signal. As noted, the first IR control signal may be generated by an IR configurator apparatus and detected by the flame detecting component of the flame detection apparatus. In some embodiments, a flame detecting component (such as, but not limited to, the flame detecting component <NUM> illustrated in connection with <FIG>) may detect the first IR control signal and provide an indication associated therewith to the processing circuitry.

Subsequent to step/operation <NUM>, the example method <NUM> proceeds to step/operation <NUM>. At step/operation <NUM>, the processing circuitry analyzes the first IR control signal (e.g., information/pulses) based on stored communication protocol information in order to identify one or more instructions contained therein. As noted above, in some embodiments, analyzing the first IR control signal and information/pulses contained therein comprises decrypting the information based at least in part on encryption keys stored in memory (such as, but not limited to, the memory <NUM> of the controller component <NUM> illustrated in connection with <FIG>, discussed above).

In some embodiments, the processing circuitry may determine that the first IR control signal does not contain any instructions or did not originate from the IR configurator apparatus. In such examples, the processing circuitry may determine not to take any further action in relation to the detected IR control signal. In another example, the processing circuitry may determine that the IR control signal contains an information request and cause generation of a second IR control signal containing the requested information. Causing generation of a second IR control signal may comprise transmitting a control indication to a IR source element (such as, but not limited to, the IR source element <NUM> illustrated in connection with <FIG>, discussed above). Causing generation of the second IR control signal may comprise causing a switch or relay connected to the IR source element (e.g., heating element) to be turned on in response to receiving the control indication.

Subsequent to step/operation <NUM>, the method <NUM> proceeds to step/operation <NUM>. At step/operation <NUM>, the processing circuitry causes configuration of at least one configuration setting associated with the flame detection apparatus. In various embodiments, causing configuration of the at least one configuration setting associated with the flame detection apparatus may comprise programmatically modifying one or more settings of a flame detecting component such as adjusting a field of view or adjusting a flame detecting component sensitivity setting. By way of example, causing modification of one or more settings of the flame detecting component may comprise increasing or decreasing a sensitivity setting. Additionally and/or alternatively, any flame detection apparatus configuration that can be adjusted using wired communication protocols as described above can also be adjusted using techniques described in the present disclosure. These settings may include, for example, without limitation fire detection apparatus output relay settings, verification time settings, false alarm rejection threshold settings, and/or the like.

Subsequent to step/operation <NUM>, the method proceeds to step/operation <NUM>. At step/operation <NUM>, the processing circuitry causes generation of a second IR control signal. In some embodiments, the second IR control signal may comprise flame detection apparatus identification information and/or metadata such that another apparatus (e.g., the IR configurator apparatus) can associate received information with a particular flame detection apparatus from a plurality of flame detection apparatuses within a network. In some embodiments, causing generation of a second IR control signal may comprise transmitting a control indication to a IR source element (such as, but not limited to, the IR source element <NUM> illustrated in connection with <FIG>, discussed above). In some examples, causing generation of the second IR control signal may comprise transmitting a control indication to an IR source element (such as, but not limited to, the IR source element <NUM> illustrated in connection with <FIG>, discussed above). Causing activation of the IR source element may comprise causing a switch or relay connected to the IR source element (e.g., heating element) to be turned on in response to receiving the control indication.

Subsequent to step/operation <NUM>, the method proceeds to step/operation <NUM>. At step/operation <NUM>, in addition to causing generation of the second IR control signal, in some embodiments, the processing circuitry causes activation of indication element(s) (such as, but not limited to, the indication elements 106A and 106B described above in connection with <FIG>). Causing activation of the indication elements may comprise causing a switch or relay connected to the indication element(s) to be turned on in response to receiving the control indication. For example, subsequent to successfully executing received instructions, the processing circuitry may cause a green LED to be turned on. In another example, in an instance in which detected conditions necessitate a status update that has not been requested, the processing circuitry may cause one or more LEDs to execute a recognizable pattern in order to notify a user to use an IR configurator apparatus to request or obtain information from the flame detection apparatus.
