FIELD OF TECHNOLOGY

This disclosure relates generally to emergency systems and, more particularly, to methods and/or a system of automatic switching between sources of breathable air within a safety system in accordance with air parameter based automatic purging of a compromised form thereof.

BACKGROUND

A structure (e.g., a vertical building, a horizontal building, a tunnel, marine craft, a mine) may have a Firefighter Air Replenishment System (FARS) implemented therein. The FARS may be employed to provide pure and safe breathable air to emergency personnel and/or maintenance personnel associated therewith. During contamination of the breathable air through the FARS and/or anomalous levels of components (e.g., carbon monoxide, carbon dioxide) thereof, the emergency and/or the maintenance personnel may be exposed to adverse health and/or life hazards thereto. Further, restoration of clean breathable air supply through the FARS may involve replacing a current source of the breathable air. The aforementioned process of the restoration of the clean breathable air supply through the FARS may prove to be fraught with hazards and/or cumbersome.

In one aspect, a method of a safety system of a structure having a fixed piping system installed therewithin to supply breathable air from a source across the safety system is disclosed. The method includes automatically purging the safety system of the breathable air based on sensing that a parameter of the breathable air is outside a predetermined threshold value. The method also includes automatically switching to another source of the breathable air following the automatic purging to enable a continued supply of the breathable air via the fixed piping system of the safety system.

In another aspect, a method of a safety system of a structure having a fixed piping system installed therewithin to supply breathable air from a source across the safety system is disclosed. The method includes, based on sensing that a parameter of the breathable air is outside a predetermined threshold, automatically triggering a shutdown of the source of the breathable air with respect to the supply of the breathable air across the safety system, and automatically purging the safety system of the breathable air. The method also includes automatically switching to another source of the breathable air following the automatic purging to enable a continued supply of the breathable air via the fixed piping system of the safety system.

In yet another aspect, a safety system of a structure includes an air storage system having a source of breathable air and another source of the breathable air, and a fixed piping system installed within the structure to supply the breathable air from the source across the safety system.

DETAILED DESCRIPTION

Example embodiments, as described below, may be used to provide methods and/or a system of automatic switching between sources of breathable air within a safety system in accordance with air parameter based automatic purging of a compromised form thereof. Although the present embodiments have been described with reference to specific example embodiments, it will be evident that various modifications and changes may be made to these embodiments without departing from the broader spirit and scope of the various embodiments.

FIG. 1A shows a safety system 100 associated with a structure 102, according to one or more embodiments. In one or more embodiments, safety system 100 may be a Firefighter Air Replenishment System (FARS) to enable firefighters entering structure 102 in times of fire-related emergencies to gain access to breathable (e.g., human breathable) air (e.g., breathable air 103) in-house without the need of bringing in air bottles/cylinders to be transported up several flights of stairs of structure 102 or deep thereinto, or to refill depleted air bottles/cylinders that are brought into structure 102. In one or more embodiments, safety system 100 may supply breathable air provided from a supply of air tanks (to be discussed) stored in structure 102. When a fire department vehicle arrives at structure 102 during an emergency, breathable air supply typically may be provided through a source of air connected to said vehicle. In one or more embodiments, safety system 100 may enable firefighters to refill air bottles/cylinders thereof at emergency air fill stations (to be discussed) located throughout structure 102. Specifically, in some embodiments, firefighters may be able to fill air bottles/cylinders thereof at emergency air fill stations within structure 102 under full respiration in less than one to two minutes.

In one or more embodiments, structure 102 may encompass vertical building structures, horizontal building structures (e.g., shopping malls, hypermarts, extended shopping, storage and/or warehousing related structures), tunnels, marine craft (e.g., large marine vessels such as cruise ships, cargo ships, submarines and large naval craft, which may be “floating” versions of buildings and horizontal structures) and mines. Other structures are within the scope of the exemplary embodiments discussed herein. In one or more embodiments, safety system 100 may include a fixed piping system 104 permanently installed within structure 102 serving as a constant source of replenishment of breathable air 103. Fixed piping system 104 may be regarded as being analogous to a water piping system within structure 102 or another structure analogous thereto for the sake of imaginative convenience.

As shown in FIG. 1A, fixed piping system 104 may distribute breathable air 103 across floors/levels of structure 102. For the aforementioned purpose, fixed piping system 104 may distribute breathable air 103 from an air storage system 106 (e.g., within structure 102) including a number of air storage tanks 108_1-N that serve as sources of pressurized/compressed air (e.g., breathable air 103). Additionally, in one or more embodiments, fixed piping system 104 may interconnect with a mobile air unit 110 (e.g., a fire vehicle) through an External Mobile Air Connection (EMAC) panel 112.

In one or more embodiments, EMAC panel 112 may be a boxed structure (e.g., exterior to structure 102) to enable the interconnection between mobile air unit 110 and safety system 100. For example, mobile air unit 110 may include an on-board air compressor to store and replenish pressurized/compressed air (e.g., breathable air analogous to breathable air 103) in air bottles/cylinders (e.g., utilizable with Self-Contained Breathing Apparatuses (SCBAs) carried by firefighters). Mobile air unit 110 may also include other pieces of air supply/distribution equipment (e.g., piping and/or air cylinders/bottles) that may be able to leverage the sources of breathable air 103 within safety system 100 through EMAC panel 112. Firefighters, for example, may be able to fill breathable air (e.g., breathable air 103, breathable air analogous to breathable air 103) into air bottles/cylinders (e.g., spare bottles, bottles requiring replenishment of breathable air) carried on mobile air unit 110 through safety system 100.

In FIG. 1A, EMAC panel 112 is shown at two locations merely for the sake of illustrative convenience. In one or more embodiments, an air monitoring system 150 may be installed as part of safety system 100 to automatically track and monitor a parameter (e.g., pressure) and/or a quality (e.g., indicated by moisture levels, carbon monoxide levels) of breathable air 103 within safety system 100. FIG. 1A shows air monitoring system 150 as communicatively coupled to air storage system 106 and EMAC panel 112 merely for the sake of example. It should be noted that EMAC panel 112 may be at a remote location associated with (e.g., internal to, external to) structure 102. In one or more embodiments, for monitoring the parameters and/or the quality of breathable air within safety system 100, air monitoring system 150 include appropriate sensors and circuitries therein. For example, a pressure sensor (to be discussed) within air monitoring system 150 may automatically sense and record a pressure of breathable air 103 of safety system 100. Said pressure sensor may communicate with an alarm system that is triggered when the sensed pressure is outside a safety range. Also, in one or more embodiments, air monitoring system 150 may automatically trigger a shutdown of breathable air distribution through safety system 100 in case of impurity/contaminant (e.g., carbon monoxide) detection therethrough yielding levels above a safety/predetermined threshold.

In one or more embodiments, fixed piping system 104 may include pipes (e.g., constituted out of stainless steel tubing) that distribute breathable air 103 to a number of emergency air fill stations 120_1-P within structure 102. In one example implementation, each emergency air fill station 120_1-P may be located at a specific level of structure 102. If structure 102 is regarded as a vertical building structure, an emergency air fill station 120_1-P may be located at each of a basement level, a first floor level, a second floor level and so on. For example, emergency air fill station 120_1-P may be located at the end of the flight of stairs that emergency fighting personnel (e.g., firefighting personnel) need to climb to reach a specific floor level within the vertical building structure.

In one or more embodiments, an emergency air fill station 120_1-P may be a static location within a level of structure 102 that provides emergency personnel 122 (e.g., firefighters, emergency responders) with the ability to rapidly fill air bottles/cylinders (e.g., SCBA cylinders). In one or more embodiments, emergency air fill station 120_1-P may be an emergency air fill panel or a rupture containment air fill station. In one or more embodiments, proximate each emergency air fill station 120_1-P, safety system 100 may include an isolation valve 160_1-P to isolate a corresponding emergency air fill station 120_1-P from a rest of safety system 100. For example, said isolation may be achieved through the manual turning of isolation valve 160_1-P proximate the corresponding emergency air fill station 120_1-P or remotely (e.g., based on automatic turning) from air monitoring system 150. In one example implementation, air monitoring system 150 may maintain breathable air supply to a subset of emergency air fill stations 120_1-P through control of a corresponding subset of isolation valves 160_1-P and may isolate the other emergency air fill stations 120_1-P from the breathable air supply. It should be noted that configurations and components of safety system 100 may vary from the example safety system 100 of FIG. 1A.

FIG. 1B shows safety system 100 of FIG. 1A integrated with and/or including other components, according to one or more embodiments. In one or more embodiments, safety system 100 shows air storage system 106 discussed above as including air storage tanks 108_1-N (example pressurized/compressed air source shown as compressed air source 108) and air compressor 130. In some embodiments, air compressor 130 may be regarded as another compressed air source 109 internal to or external to structure 102, as will be discussed below. In one or more embodiments, air monitoring system 150 discussed above may include an air quality analysis device 105 (e.g., a programmable electromechanical device) to determine quality of breathable air 103 within safety system 100. In order to do this, in one or more embodiments, air quality analysis device 105 may be communicatively coupled to air storage system 106.

In one or more embodiments, air quality analysis device 105 may continuously and/or intermittently measure and analyze components of breathable air 103 within safety system 100. Further, in one or more embodiments, air quality analysis device 105 may compare the results of the analyses to standard fire safety guidelines 152 pertaining to the breathable air (e.g., breathable air 103) programmed therewithin, as shown in FIG. 1B. Alternatively or additionally, in some embodiments, standard fire safety guidelines 152 may exist on an external device (e.g., data processing device 136 to be discussed below/server) and accessed through air quality analysis device 105.

In one or more embodiments, air quality analysis device 105 may include a set of sensors 172_1-Q to monitor parameters associated with quality of breathable air 103 and components thereof within safety system 100. In one or more embodiments, sensors 172_1-Q may continuously (and automatically be programmed to) monitor the quality of breathable air 103 from air storage system 106 that is being supplied to the various emergency air fill stations 120_1-P within structure 102. In one or more embodiments, once a deviation in an air parameter (e.g., temperature, pressure, contamination, carbon monoxide component, carbon dioxide component etc.) is detected by sensors 172_1-Q, air quality analysis device 105 may automatically activate a bypass controller device 140 (e.g., another programmable/controllable electromechanical device) to automatically switch off supply of breathable air 103 from compressed air source 108.

For example, bypass controller device 140 may control isolation valves 160_1-P associated with emergency air fill stations 120_1-P to automatically bypass compressed air source 108 (e.g., air storage tanks 108_1-N) with respect to breathable air 103 within safety system 100; appropriate control (e.g., closing) of isolation valves 160_1-P may shut down breathable air 103 from compressed air source 108 to emergency air fill stations 120_1-P. Further, in response to the automatic bypass of compressed air source 108, bypass controller device 140 may automatically connect emergency air fill stations 120_1-P to another compressed air source 109 of air storage system 106 as the source of breathable air 103 within safety system 100. Here, in one or more embodiments, isolation valves 160_1-P may, again, be controlled to be, for example, opened to let another compressed air source 109 supply breathable air 103 within safety system 100. Thus, in one or more embodiments, the automatic switching between compressed air sources within safety system 100 may be accomplished through sensing/monitoring of parameters of breathable air 103 therewithin; such a switch may ensure a continuous, uninterrupted supply of breathable air 103 within safety system 100.

In one or more embodiments, the automatic switching between compressed air sources within safety system 100 may occur based on controlling isolation valves 192 associated with compressed air source 108 and another compressed air source 109 within air storage system 106. For example, automatic closing of an isolation valve 192 associated with compressed air source 108 within air storage system 106 and automatic opening of another isolation valve 192 associated with another compressed air source 109 based on detection of deviation in parameters of components of breathable air 103 may result in the automatic switching between compressed air sources within safety system 100. Another compressed air source 109 (e.g., air compressor 130) may be internal to structure 102 or external (e.g., mobile air unit 110 connected to safety system 100 through EMAC panel 112) thereto.

In one or more embodiments, emergency personnel 122 (e.g., firefighters, emergency responders, maintenance personnel, control room personnel) at data processing device 136 (e.g., a mobile phone, a tablet, a server, a laptop, a computing device) may request one or more air quality tests on breathable air 103 through air quality analysis device 105. In one or more embodiments, said request 176 may activate (e.g., automatically) air quality analysis device 105 to obtain an air sample 178 of breathable air 103. For example, air quality analysis device 105 may allow a predetermined quantity/volume of breathable air 103 pass through a chamber (not shown) thereof to enable air sample 178 to be procured for said one or more quality tests. Alternatively or additionally, air quality analysis device 105 may allow breathable air 103 to pass through the chamber for a predetermined duration to enable air sample 178 to be procured for the one or more quality tests.

FIG. 2 shows air quality analysis device 105, according to one or more embodiments. In some embodiments, air quality analysis device 105 may be integrated with fixed piping system 104 to be along the path of flow of breathable air 103. In other embodiments, air quality analysis device 105 may be part of air monitoring device 150 or even air storage system 106. In some other embodiments, air quality analysis device 105 may merely be along a flow path of breathable air 103 of safety system 100. In one or more embodiments, air quality analysis device 105 may include an intake pump 206 to ingest a quantity/volume of breathable air 103 through fixed piping system 104 into an air sequestration chamber 214, thereby segregating air sample 178 of breathable air 103 for analysis. In one or more embodiments, air sequestration chamber 214 may be communicatively coupled to sensors 172_1-Q that analyze air sample 178 therewithin and perform operations and functionalities related to monitoring and/or sensing parameters related to air quality and components of breathable air 103 within safety system 100.

In one or more embodiments, a chipset 212 coupled to a memory 208 (e.g., a volatile and/or a non-volatile memory) may, in turn, be electrically coupled to sensors 172_1-Q to convert results of the sensing and/or monitoring into machine (e.g., a data processing device such as data processing device 136) readable/interpretatable air quality data 128 (e.g., stored in memory 208); said air quality data 128 may be communicable to a remote certification laboratory 118 (referring back to FIG. 1B) through a computing network (e.g., cloud computing network 114). Thus, in one or more embodiments, analysis and/or certification of breathable air 103 through safety system 100 by professionals may be enabled through safety system 100. As shown in FIG. 2, memory 208 and chipset 212 may be communicatively coupled to a processor 218 (e.g., a microcontroller) that executes instructions associated with the abovementioned operations and/or functionalities. For this purpose, in one or more embodiments, memory 208 may include instructions associated with an analysis module 220 stored therein that are executable through processor 218.

In one or more embodiments, remote certification laboratory 118 may analyze air quality data 128 of air sample 178 and automatically generate an alert signal 194 to activate bypass controller device 140 if anomalies (e.g., due to air contamination, particulates, pollutants, etc.) and/or faults (e.g., deviation from predefined parameters such as temperature, pressure, a proportion of air components, etc.) are detected in air quality data 128. In one or more embodiments, for the aforementioned purpose, bypass controller device 140 may automatically generate signals to control isolation valves 160_1-P/isolation valves 192, as discussed above. In addition, in one or more embodiments, air quality data 128 may be communicated to a fire command center 115 (e.g., a remote center with data processing capabilities), a fire control room 113 (e.g., a control room internal to or external to structure 102) and/or emergency personnel 122 at data processing device 136 through cloud computing network 114.

In one or more embodiments, remote certification laboratory 118 alone may not generate alert signal 194. In one or more embodiments, based on monitoring and/or sensing of breathable air 103 and components thereof through air quality analysis device 105 as discussed above, alert signal 194 may be directly generated through air quality analysis device 105, for example, based on an alert system shown) implemented therein. As discussed above, in accordance therewith, bypass controller device 140 coupled to air monitoring system 150 may generate signals to automatically bypass air storage system 106 (e.g., compressed air source 108) with respect to supply of breathable air 103 within safety system 100 and/or automatically switch between compressed air sources (e.g., between compressed air source 108 and another compressed air source 109 and/or vice versa).

In one or lore embodiments, air quality analysis device 105 may be permanently affixed (or, along a path of breathable air 103 within fixed piping system 104) to fixed piping system 104 to avoid logistical issues related to building an analogous sensing/monitoring mechanism offsite, and/or to reduce the risk of breathing contaminated air causing harm to emergency personnel 122 during an emergency (e.g., air contamination, air pollution, fire, smoke).

In one or more embodiments, as shown in FIG. 2, memory 208 of air quality analysis device 105 may include known calibration data 210 stored therein that is used by processor 218 (e.g., by analysis module 220) to compare a characteristic/parameter of breathable air 103 therewith based on results of analysis through remote certification laboratory 118 and/or air quality analysis device 105. In one or more embodiments, in response to determining through processor 218 that the characteristic/parameter is dissimilar to one car more of known calibration data 210, control parameters 222 (e.g., stored in memory 208) of air quality analysis device 105 may be adjusted to account for said dissimilarities. Also, in one or more embodiments, air quality analysis device 105 may include appropriate circuitry to receive instructions from fire command center 115, fire control room 113 and/or data processing device 136 (emergency personnel 122) to mark/alert safety system 100 for transitioning thereof into an emergency state and/or generate trigger signals to activate bypass controller device 140 for automatic bypass of air storage system 106/compressed air source 108/another compressed air source 109 discussed above. Again, in one or more embodiments, the same functionalities may be provided to air quality analysis device 105 itself.

In one or more embodiments, as shown in FIG. 1B, remote certification laboratory 118 may include an analysis unit 124 (e.g., a data processing device such as a server) including a processor 182 (e.g., a processor core, a network of processors, a processor) communicatively coupled to a memory 184 (e.g., a volatile and/or a non-volatile memory and/or a database). In one or more embodiments, memory 184 may have historical data 186 (e.g., relevant to safety system 100 and breathable air 103 therein) and predefined air quality parameters/thresholds 188 (e.g., as per National Fire Protection Association (NFPA) standards, as per general and/or custom safety standards) for breathable air 103. In one or more embodiments, analysis unit 124 may measure air quality parameters 190 (also shown as part of memory 208 of air quality analysis device 105 to account for air quality analysis device 105 performing operations analogous to analysis unit 124 including triggering bypass controller device 140 to automatic bypass air storage system 106/compressed air source 108/another compressed air source 109 discussed above) using air quality data 128. In some embodiments, analysis unit 124 may execute one or more artificial intelligence algorithms 191 (e.g., stored in memory 184 and executable through processor 182) for advanced profiling and/or testing of breathable air 103 through safety system 100.

In some embodiments, the profiling and/or testing through analysis unit 124 of remote certification laboratory 118 may provide for accreditation of air quality of breathable air 103 within safety system 100 when the results of the profiling/testing yield that air quality parameters 190 are within the predefined air quality parameters/thresholds 188; the aforementioned accreditation may be provided in the form of a certificate to fire command center 115, fire control room 113 and/or data processing device 136 (emergency personnel 122). In some embodiments, each time safety system 100 is certified, the corresponding certification generated may be written permanently into a distributed ledger and/or a blockchain (e.g., Ethereum™ blockchain, Solana™ blockchain; part of memory 184 or a cloud version thereof) for redundant and secondary record-keeping. In addition, advanced reporting, analytics, control and/or test functions may be enabled through a mobile and/or a desktop application (e.g., executing on data processing device 136).

In one or more embodiments, when the results of the profiling/testing yield that air quality parameters 190 are not within predefined air quality parameters/thresholds 188, remote certification laboratory 118/analysis unit 124 may generate alert signal 194 to notify fire command center 115, fire control room 113 and/or data processing device 136 (emergency personnel 122) of an emergency state of safety system 100. In some implementations, alert signal 194 may automatically activate bypass controller device 140 to switch off supply of breathable air 103 from compressed air source 108/another compressed air source 109/air storage system 106 and, thereby, isolate compressed air source 108/another compressed air source 109/air storage system 106 from safety system 100. Alert signal 194 additionally may activate bypass controller device 140 to automatically connect a different compressed air source (e.g., another compressed air source 109) to safety system 100/emergency air fill stations 120_1-P to ensure a continuous supply of breathable air 103 within safety system 100, according to one or more embodiments.

FIG. 3 shows constituent sensors of sensors 172_1-Q, according to one or more embodiments. In one or more embodiments, sensors 172_1-Q may include a hydrocarbon sensor 302 to measure a hydrocarbon level to an accuracy of, say, 0.02-0.3% absolute, an oxygen sensor 304 to measure an oxygen level to an accuracy of, say, 0.1% absolute, a nitrogen sensor 306, a nitric oxide sensor 310, a carbon monoxide sensor 314, a carbon dioxide sensor 316, a moisture sensor 318, an oil and particle sensor 320 to measure a level of oil and/or particle to an accuracy of, say, ±2% relative, a sulfur dioxide sensor 312, a pressure sensor 324, an odor sensor 322 and/or a leakage sensor 326. In one or more embodiments, the automatic bypassing of air storage system 106/compressed air source 106/another compressed air source 109 through bypass controller device 140 may be initiated when one or more of the following conditions are detected through the corresponding sensors 172_1-Q:

• • 1. carbon monoxide sensor 314 detects a level of carbon monoxide in breathable air 103 in excess of a first predetermined threshold value (e.g., 4.5 parts per million; part of predefined air quality parameters/thresholds 188 shown as stored in both memory 184 and memory 208),
  • 2. carbon dioxide sensor 316 detects a level of carbon dioxide in breathable air 103 in excess of a second predetermined threshold value (e.g., 1,000 parts per million; part of predefined air quality parameters/thresholds 188),
  • 3. oxygen sensor 304 detects a level of oxygen in breathable air 103 outside a predetermined range of values (e.g., between 19.5% and 23.5; part of predefined air quality parameters/thresholds 188),
  • 4. nitrogen sensor 306 detects a level of nitrogen in breathable air 103 less than a third predetermined threshold value (e.g., below 75%; part of predefined air quality parameters/thresholds 188) and/or in excess of a fourth predetermined threshold value (e.g., above 81%; part of predefined air quality parameters/thresholds 188),
  • 5. hydrocarbon sensor 302 detects a condensed hydrocarbon content in breathable air 103 in excess of a fifth predetermined threshold value (e.g., 5 milligrams per cubic meter of breathable air 103; part of predefined air quality parameters/thresholds 188),
  • 6. moisture sensor 318 detects a moisture concentration in breathable air 103 in excess of a sixth predetermined threshold value (e.g., 24 parts per million by volume; part of predefined air quality parameters/thresholds 188), and
  • 7. pressure sensor 324 detects a pressure of breathable air 103 less than a seventh predetermined threshold value (e.g., below 90% of a maintenance pressure specified in a fire code; part of predefined air quality parameters/thresholds 188).

Other types of sensors that are part of sensors 172_1-Q have analogous predetermined threshold values/ranges (e.g., part of predefined air quality parameters/thresholds 188) associated with air quality parameters 190 sensed therethrough; such sensors 172_1-Q are shown in FIG. 3 and are self-explanatory. It should be noted that parameters sensed through sensors 172_1-Q may not be limited to air quality parameters 190; even characteristics such as pressure (e.g., through pressure sensor 324) may be sensed through sensors 172_1-Q. Also, in one or more embodiments, leakage of breathable air 103 from safety system 100 (e.g., fixed piping system 104, at emergency air fill stations 120_1-P, isolation valves 160_1-P, air storage system 106 such as compressed air source 108/air storage tanks 108_1-N/another compressed air source 109) may also be sensed through appropriate sensors 172_1-Q (e.g., leakage sensor 326). In one example implementation, leakage sensor 326 may be an ultrasound sensor that senses high sound frequencies of leaks of breathable air 103. Said leaks, if not addressed appropriately, may result in catastrophic loss of breathable air 103 from safety system 100. In one or more embodiments, once sensors 172_1-Q detect the leakage of breathable air 103, again, bypass controller device 140 may automatically be triggered to bypass air storage system 106/compressed air source 108/another compressed air source 109, as discussed above.

Thus, in one or more embodiments, the capabilities of air quality analysis device 105 and/or remote certification laboratory 118 may be extended to accommodate detection of parameters such as pressure and leakage of breathable air 103. All reasonable variations are within the scope of the exemplary embodiments discussed herein.

FIG. 4 shows air monitoring system 150 discussed above in an example implementation form. Here, air monitoring system 150 may be a collection of units and/or components put together to check and record quality (and/or pressure/leakage) of breathable air 103 and components thereof within safety system 100. Air quality analysis device 105 may include a display unit 402 associated therewith (e.g., part of or external to air quality analysis device 105). to exhibit air quality parameters 190 captured and/or analyzed through air quality analysis device 105.

A video camera (not shown) installed on or integrated with display unit 402 may capture visual incidents at the key locations that are accessible at fire command center 115, fire control room 113 and/or data processing device 136 through cloud computing network 114. Air quality parameters 190 may be monitored in accordance with standard fire safety guidelines (e.g., NFPA guidelines, Occupational Safety and Health Administration (OSHA) and/or Compressed Gas Association (CGA) standards).

FIG. 5 shows an example display unit 402 associated with air quality analysis device 105 of FIG. 4. Display unit 402 may include various indicator fields to exhibit air quality parameters 190 captured and/or analyzed by air quality analysis device 105 in real-time. For example, indicator field 502 may be associated with carbon monoxide content in breathable air 103 (e.g., from air storage system 106/compressed air source 108), indicator field 504 may be associated with carbon dioxide content in breathable air 103, indicator field 510 may be associated with nitrogen content in breathable air 103, indicator field 506 may be associated with moisture content breathable air 103, indicator field 508 may be associated with oxygen content in breathable air 103, and indicator field 512 may be associated with hydrocarbon content in breathable air 103. In addition, display unit 402 may include a pressure indicator 514 to exhibit air pressure of breathable air 103 (e.g., air sample 178).

Further, display unit 402 may include indicator lights (not shown) to indicate changes in air quality parameters 190 through changes in colors of lights emitted therefrom. Still further, display unit 402 may include, for example, a Quick Response (QR) scanner (not shown) to enable emergency personnel 122 to scan and check statuses of air quality parameters 190.

FIG. 6 shows an example air quality analysis device 105. Air quality analysis device 105 may include a flow sensor 602 (e.g., an electronic device) that measures and/or regulates a flow rate of breathable air 103 (e.g., from compressed air source 108, another compressed air source 109) within fixed piping system 104. A photoionization detector (PID) sensor 604 of air quality analysis device 105 may detect low concentrations of volatile organic compounds (VOCs)/hazardous substances in breathable air 103. In one example implementation, PID sensor 604 may utilize ultraviolet (UV) light to break down said VOCs in breathable air 103 into positive and negative ions, following which a charge of the ionized gas as a function of concentration of the VOCs in breathable air 103 is detected and/or measured.

A Metal Oxide Semiconductor (MOS) sensor 606 of air quality analysis device 105 may detect concentrations of various types of gases in breathable air 103/air sample 178 by measuring a change in resistance of a metal oxide due to adsorption of gases in breathable air 103/air sample 178. An infrared (IR) sensor 608 of air quality analysis device 105 may measure and/or detect infrared radiation in a surrounding environment of air quality analysis device 105. All sensors discussed herein may be part of sensors 172_1-Q discussed above.

Outputs 610 may be in the form of electrical signals used to identify air components of breathable air 103/air sample 178. The electrical signals may be generated by sensors 172_1-Q including the sensors discussed herein. An input 612 may be an intake of breathable air 103/air sample 178 (e.g., through a hose) from compressed air source 108/another compressed air source 109/air storage system 106.

An electromechanical gas sensor 616 of air quality analysis device 105 may be operated based on a diffusion of a gas of interest (e.g., air components of breathable air 103/air sample 178) thereinto. Said diffusion may result in generation of an electrical signal proportional to a concentration of the gas of interest. A dew point sensor 618 of air quality analysis device 105 may be used to measure and/or monitor a dew point temperature of breathable air 103/air sample 178. An audio alarm 620 may be a transducer device to emit an audible alert once an emergency state is detected by sensors 172_1-Q. A power input 622 may be an input corresponding to an amount of energy put into and/or consumed by air quality analysis device 105.

In one or more embodiments, air monitoring system 150 may be made of fire-rated material to protect safety system 100 from physical damage during hazardous situations. Further, in one or more embodiments, air monitoring system 150 may be made of weather-resistant and/or UV/solar/infrared radiation-resistant material/material(s) to prevent corrosion and/or deterioration of components thereof due to prolonged exposure to harsh environmental and/or weather conditions.

FIG. 7 shows safety system 100 implemented in a horizontal configuration of structure 102 and communication therewithin, according to one or more embodiments. All concepts discussed in this Application may also be applicable to FIG. 7. FIG. 8 shows an example user interface 852 of an air safety application 850 executing on data processing device 136 (e.g., on a processor communicatively coupled to a memory thereof). As shown in ‘(a)’, user interface 852 may display user authentication tabs of air safety application 850. Example user authentication tabs may include an identification number tab 802, a username tab 804, and a password tab 806. Emergency personnel 122 (e.g., authorized users, firefighters, emergency responses) may need to enter a corresponding identification number, username and password to access features provided through air safety application 850.

As shown in ‘(b)’, upon authentication, example user interface 854 may display a remote Human-Machine Interface (HMI) tab 808, a mobile dashboard tab 810, a test tab 812, and a maintenance tab 814. Remote HMI tab 808 may help emergency personnel 122 to remotely control safety system 100. Mobile dashboard tab 810 may help show a real-time graphical display of an entirety of safety system 100. Test tab 812 may help emergency personnel 122 to request analysis of breathable air 103 through remote certification laboratory 118 and generate custom reports. Maintenance tab 814 may help provide a proactive dimension to view upcoming and/or current maintenance requirements of safety system 100.

As shown in ‘(c)’, remote HMI tab 808 may display an emergency air fill station tab 816, an air monitoring system tab 818, an air storage system tab 820, an isolation tab 822, a bypass control system tab 824, and an EMAC panel tab 826. Remote HMI tab 808 may enable emergency personnel 122 to control components associated with the aforementioned tabs to effect automatic bypass of air storage system 106/compressed air source 108/another compressed air source 109, as discussed above, and obtain air quality parameters 190. Based on zeroing in on specific tabs discussed herein, more detailed operations such as controlling relay devices, requesting certification through remote certification laboratory 118, purging breathable air 103 from safety system 100, isolating compressed air source 108/another compressed air source 109/air storage system 106 and so on are within the scope of the exemplary embodiments discussed herein.

In one or more embodiments, based on detection of emergency state(s) of safety system 100 and/or anomalous air quality parameters 190 through sensors 172_1-Q via data processing device 136, fire command center 115 and/or fire control room 113, emergency personnel 122 may be able to purge safety system 100 of contaminated/bad/anomalous breathable air 103 prior to switching from one compressed air source (e.g., compressed air source 108) to another compressed air source (e.g., another compressed air source 109). In some other embodiments, leakage (e.g., detected through leakage sensor 326) of breathable air 103 may require plugging in of leak(s) in components of safety system 100 and/or fixing said components prior to reuse of the same compressed air source (e.g., air storage system 106, compressed air source 108, another compressed air source 109). The aforementioned tasks are instantaneously notified to emergency personnel 122 in accordance with one or more implementations of safety system 100 discussed herein. All reasonable variations are within the scope of the exemplary embodiments discussed herein.

It should be noted that, in one or more embodiments, in the case of another compressed air source 109 being mobile air unit 110 with air compressor 130, bypass controller device 140 may be implemented with one or more check valves and/or one or more automatic actuator selector valves remotely operable from EMAC panel 112 readily accessible by emergency personnel 122. FIG. 9 shows control of valves 902 (e.g., check valves, automatic actuator selector valves) implemented in conjunction with bypass controller device 140/isolation valve 192/isolation valves 160_1-P remotely from EMAC panel 112 by emergency personnel 122, according to one or more embodiments. In one or more embodiments, in response to an electrical signal 904 from EMAC panel 112 (e.g., following detection of anomalies/faults in air quality parameters 190), valves 902/isolation valve 192/isolation valves 160_1-P may be controlled to enable automatic bypass/isolation of compressed air source 108 with respect to breathable air 103 within safety system 100 and automatic switching to another compressed air source 109 (e.g., air compressor 130 on mobile air unit 110) to ensure direct and continued supply of breathable air 103 from another compressed air source 109 within safety system 100. In the case of control of isolation valve 192/isolation valves 160_1-P through electrical signal 904, isolation valve 192 and/or isolation valves 160_1-P may also be implemented with check valves and/or automatic actuator selector valves. All reasonable variations are within the scope of the exemplary embodiments discussed herein.

FIG. 10 shows automatic purging of breathable air 103 within safety system 100, according to one or more embodiments. In one or more embodiments, as seen above, alert signal 194 (or even electrical signal 904) to activate bypass controller device 140 may further activate a breathable air purging system 1002 coupled to fixed piping system 104. It should be noted that, as discussed above, in one or more embodiments, alert signal 194 may be transmitted from remote certification laboratory 118 and air quality analysis device 105. In some embodiments, alert signal 194 may even be transmitted from data processing device 136 (e.g., a mobile device) of authorized emergency personnel 122 to activate bypass controller device 140 and/or breathable air purging system 1002. Here, in one or more embodiments, bypass controller device 140 and breathable air purging system 1002 may be wirelessly controllable based on coupling (e.g., via a computer network such as cloud computing network 114 or a computer network 1004 (e.g., a Wide Area Network (WAN), a Local Area Network (LAN), a short-range communication network)) thereof to data processing device 136, remote certification laboratory 118 and/or air quality analysis device 105.

Thus, in one or more embodiments, all discussions relevant to automatically bypassing the source (e.g., compressed air source 108, another compressed air source 109) of breathable air 103 based on sensing (e.g., the predetermined threshold based sensing through sensors 172_1-Q discussed above) one or more parameter(s) (e.g., air quality parameters 190) of breathable air 103 may also be applicable to automatically purging breathable air 103 within safety system 100 or at least a portion thereof and switching from compressed air source 108 to another compressed air source 109. In one or more embodiments breathable air purging system 1002 may include a vacuum pump 1006 that is electronically controllable (e.g., operable based on alert signal 194). In one or more embodiments, vacuum pump 1006 may have an inlet section 1008 to take in breathable air 103 compromised in quality (e.g., detected based on air quality parameters 190) from safety system 100 and an exhaust outlet section 1010 from which the compromised breathable air 103 is let out (e.g., as waste; in a controlled manner). In one or more embodiments, exhaust outlet section 1010 may be part of fixed piping system 104 as shown in FIG. 10.

In one or more embodiments, in response to detecting that one or more air quality parameters 190 is outside one or more predetermined threshold values (e.g., predefined air quality parameters/thresholds 188) based on the sensing discussed above through one or more sensors 172_1-Q, alert signal 194 may be transmitted to breathable air purging system 1002; said alert signal 194 may trigger the switching on of vacuum pump 1006 automatically. In one or more embodiments, as breathable air 103 may be input to vacuum pump 1006 based on coupling of breathable air purging system 1002 to fixed piping system 104, the switching on of vacuum pump 1006 may suck in breathable air 103 through vacuum pump 1006 via inlet section 1008.

In one or more embodiments, vacuum pump 1006 may be coupled across a low-pressure point of safety system 100 and a high-pressure point associated with fixed piping system 104 representing a system pressure of breathable air 103 within safety system 100. In one or more embodiments, the purging of breathable air 103 out of safety system 100 (or at least a portion thereof) may enable the automatic switching from one source (e.g., compressed air source 108) to another (e.g., another compressed air source 109) as a new source of clean breathable air 103, as discussed above.

In some other embodiments, in response to alert signal 194, bypass controller device 140 may automatically bypass compressed air source 108 with respect to breathable air 103 within safety system 100, following which bypass controller device 140 may transmit another alert signal (e.g., alert signal 1012 of FIG. 10) to activate breathable air purging system 1002/vacuum pump 1006 instead of alert signal 194.

FIG. 11 shows air storage system 106 with compressed air source 108 and another compressed air source 109 communicating with bypass controller device 140 and breathable air purging system 1002, according to one or more embodiments. In one or more embodiments, compressed air source 108 and another compressed air source 109 may have an air compressor 1102 and air compressor 130 associated therewith respectively. Alternately, in some implementations, air compressor 1102 and air compressor 130 may be regarded as compressed air source 108 and another compressed air source 109 respectively.

Air compressor 1102 and air compressor 130 may both operate based on pressurizing air forced thereinto and then releasing breathable air 103 through fixed piping system 104, according to one or more embodiments. In one or more embodiments, as discussed above, bypass controller device 140 may automatically transmit an alert signal (e.g., alert signal 1012 analogous to alert signal 194 to breathable air purging system 1002 or air storage system 106) to switch from compressed air source 108 to another compressed air source 109. For the aforementioned purpose, in one or more embodiments, air storage system 106 may include an electronically controllable/operable switch 1104 that, in response to an alert signal (e.g., response signal 1152 analogous to alert signal 194/alert signal 1012 to be discussed below), shuts down or turns on compressed air source 108 and/or another compressed air source 109.

In one or more embodiments, in a state of operation of compressed air source 108 (and, thereby, air compressor 1102), a switch element 1106 of switch 1104 may be ON. In one or more embodiment, based on air quality analysis device 105/remote certification laboratory 118/data processing device 136 detecting or initiating the detection that one or more air quality parameters 190 is outside one or more predetermined threshold values (e.g., predefined air quality parameters/thresholds 188) based on the sensing thereof through sensors 172_1-Q of air quality analysis device 105, an alert signal (e.g., alert signal 194/alert signal 1012/an alert signal analogous to response signal 1152 or another analogous alert signal) may be transmitted to air storage system 106 to trigger a shutdown of compressed air source 108 by way of turning OFF switch element 1106. In one or more embodiments, automatic purging of breathable air 103 (e.g., compromised based on the detection above) out of safety system 100 may then be accomplished utilizing breathable air purging system 1002 as discussed above.

In one or more embodiments, following the purging, breathable air purging system 1002 (or bypass controller device 140 based on electronic detection of the completion of purging) may automatically trigger the switching ON/turning ON of another compressed air source 109 (air compressor 130) by way of another switch element 1108 of switch 1104. In one or more embodiments, the activation of another compressed air source 109 may cause clean breathable air 103 to be supplied through fixed piping system 104 across safety system 100. For example, the condition of vacuum pump 1006 of breathable air purging system 1002 not being able to suck more of the compromised breathable air 103 in may be sensed through a sensor 1150 (e.g., a pressure sensor that detects a drop in pressure at inlet section 1008 due to the compromised breathable air 103 being completely sucked in and let out through exhaust outlet section 1010) that transmits an appropriate signal (e.g., response signal 1152) back to bypass controller device 140 or to air storage system 106 that also includes control circuitry 1170 (FIG. 11 shows both bypass controller device 140 and air storage system 106 as including the same control circuitry 1170 for example purposes) therein to interpret said response signal 1152 to automatically trigger switching between the sources through switch 1104.

In one or more embodiments, alert signal 1012 (or analogous alert signals such as alert signal 194/response signal 1152) may additionally trigger shutdown of supply of the compromised breathable air 103 to one or more components (e.g., emergency air fill stations 120_1-P) of safety system 100 to ensure that the compromised breathable air 103 is not accessed by emergency personnel 122 and/or other authorized personnel. As discussed above, for example, in response to alert signal 194/1012 or an alert signal analogous to response signal 1152, bypass controller device 140 may control isolation valves 160_1-P associated with emergency air fill stations 120_1-P to automatically bypass compressed air source 108 (e.g., air storage tanks 108_1-N) with respect to breathable air 103 within safety system 100; appropriate control (e.g., closing) of isolation valves 160_1-P may shut down breathable air 103 from compressed air source 108 to emergency air fill stations 120_1-P. Thus, in one or more embodiments, the automatic purging of the compromised breathable air 103 out of safety system 100 may occur in conditions of emergency air fill stations 120_1-P bypassing the source (e.g., compressed air source 108) of the compromised breathable air 103 or not receiving the compromised breathable air 103.

Variations in implementations of vacuum pump 1006 (e.g., a two-chamber vacuum pump may be employed), breathable air purging system 1002, air storage system 106, air compressor 1102, air compressor 130 and control mechanisms discussed herein are also within the scope of the exemplary embodiments discussed herein. Similarly, FIG. 12 shows control of air storage system 106 through bypass controller device 140 (e.g., via alert signal 1012) and/or response signal 1152 from breathable air purging system 1002 discussed above to enable switching from compressed air source 108 to another compressed air source 109 based on activation of another compressed air source 102 through switch 1104, according to one or more embodiments. In one or more embodiments, air storage system 106 may also be wirelessly controllable based on coupling (e.g., via cloud computing network 114 or a computer network 1004) thereof to data processing device 136, remote certification laboratory 118 and/or air quality analysis device 105/air monitoring system 150.

It should be noted that, in some implementations, another compressed air source 109 may be operating while compressed air source 108 supplies breathable air 103 to safety system 100. Here, detection of compromised breathable air 103 from compressed air source 108 may cause switching to another compressed air source 109 through switch 1104. Last but not the least, it should be noted that, in some implementations, the automatic switching between compressed air source 108 and another compressed air source 109 to ensure continued supply of breathable air 103 across safety system 100 may be initiated following a certification of clearance with regard to the compromised form of breathable air 103 having been completely purged from safety system 100. All reasonable variations are within the scope of the exemplary embodiments discussed herein.

FIG. 13 shows a process flow diagram detailing the operations involved in automatic switching between sources of breathable air (e.g., breathable air 103) within a safety system (e.g., safety system 100) in accordance with air parameter based automatic purging of a compromised form thereof, according to one or more embodiments. In one or more embodiments, the breathable air may be supplied across the safety system from a source (e.g., compressed air source 108) thereof via a fixed piping system (e.g., fixed piping system 104) implemented therein. In accordance therewith, in one or more embodiments, operation 1302 may involve automatically purging (e.g., using purge valve 1402 (discussed below) and/or vacuum pump 1006 of breathable air purging system 1002) the safety system of the breathable air based on sensing (e.g., through sensors 172_1-Q of air quality analysis device 105) that a parameter (e.g., one or more of air quality parameters 190) of the breathable air is outside a predetermined threshold value (e.g., one or more predefined air quality parameters/thresholds 188). In one or more embodiments, operation 1304 may then involve automatically switching (e.g., utilizing bypass controller device 140) to another source (e.g., another compressed air source 109) of the breathable air following the automatic purging to enable a continued supply of the breathable air via the fixed piping system of the safety system.

It should be noted that the automatic purging of breathable air 103 from safety system 100 discussed above may not be limited to utilization of vacuum pump 1006 therefor. FIG. 14 shows utilization of a purge valve 1402 instead of vacuum pump 1006 in breathable air purging system 1002 of FIGS. 10-12, according to one or more embodiments. In one or more embodiments, purge valve 1402 may be an isolation valve 192, a valve 902, an isolation valve 160_1-P and/or another valve. In one or more embodiments, purge valve 1402 may be electronically controllable (e.g., operable based on alert signal 194) in the same manner as vacuum pump 1006 discussed above. In one or more embodiments, inlet section 1008 and exhaust outlet section 1010 (e.g., part of fixed piping system 104) may also be associated with purge valve 1402 analogous to the vacuum pump 1006 implementation. Thus, all discussions relevant to the vacuum pump 1006 based purging above may also be applicable to the purge valve 1402 based implementation of FIG. 14. Further, other kinds of automatic purging based on utilization of system air (or another gas) within safety system 100 and/or continuous point-to-point flows are also within the scope of the exemplary embodiments discussed herein. All reasonable variations are within the scope of the exemplary embodiments discussed herein.
