The present invention relates generally to the field of detecting a fire event. More specifically, the present invention relates to response options during a fire event.
The application of monitoring equipment to detect anomalous or dangers activity, and the application of robotically controlled nozzles to provide fire-fighting capabilities is well documented in large systems such as buildings, fire trucks, and fire boats. In these systems the interpretation of the monitored activity and control of the response actions such as the use of robotic firefighting nozzles is provided by personnel operators who detect and locate the fire, and manually direct the stream of the firefighting agent, which is normally water, to the location of the fire, for the purpose of extinguishing it.
The standard methodologies of providing space monitoring and firefighting protection to a space prior to the arrival of the fire department, is through either, generally, personalized manual systems, or automated untargeted systems. For example, a personalized manual system may have the use of special purpose sensors to detect a fire event, cameras for providing visual information to an operator, and the manual employment of portable fire-fighting agents in a bottle by an operator.
Alternatively, automated systems may have the use of automatically triggered fixed systems providing water, foam, CO2, powder, water mist and wet chemical agents. These systems act by cooling, smothering, starving, or interrupting the combustion process to extinguish the fire. Fixed firefighting systems are typically comprised of large reservoirs of fire-fighting agent, a delivery system comprised of pipes, nozzles, pumps, and/or pressurized bottles, and an activation system that detects and releases the fire-fighting agent.
The present invention is similar to the prior art systems in that it is a system that is designed to be reactionary to the detection of an actual fire event. However, the present invention seeks to overcome the disadvantages of the fixed systems which are intended to protect an overall space and operation from the damage of a fire but result in a certain level of consequential damage themselves. For example, the application of large amounts of water, chemical, or foam agents into a space can irreversibly damage electronic equipment, paper supplies, and food inventories, and in general, anything stored in that space.
Table 1 provides an amended listing of fixed firefighting systems from the International Journal of Information Technology ISSN (2413-2950) Volume 1, 12 Dec. 2019 (amended by inventor with noted potential collateral damage sought to be overcome by the present invention).
The same is true for other fire suppressing chemical agents as these systems are an essential fire safety tool, protecting the loss of property that results from a fire—but in the prior art usage there is no provision to prevent the loss of property that results from indiscriminate deployment of the agents themselves. Other approaches to evaluative threat prediction, detection, and response include the autonomous deployment of threat reduction actions and agents, including, but not limited to closure of doors, securing of fuel supplies, reduction of air flows, deployment of selected suppression agents, etc.
The present invention relates generally to equipping spaces with sensor packages, computational resources, and threat response equipment including firefighting extinguisher equipment, comprised of but not limited to firefighting agent bottles with controlled valves, robotic nozzle assemblies, communication capability, and sensor electronics that are able to predict, detect, classify and localize an emergent threat, including but not limited to an emergent/impending or actual fire event, and through the use of a suite of autonomously controlled equipment including but not limited to robotic nozzle positioning mechanisms, fire agent valves, firefighting agents, fire preventive agents, targeting software and control mechanisms, and related equipment control systems, autonomously predict, and respond to an impending or existing threat with the engagement and disbursement of a selected threat response agent, including but not limited to fire-fighting agent(s) onto a fire to extinguish it, or a preventive agent onto an enabling event, such as a fuel spill, oil spill, or other unintended flammable agent dispersant, to prevent the enabling event from developing into a more serious threat. The invention includes sophisticated software such as machine learning software to characterize normal space activity to be used to detect anomalous activity, and artificial intelligence software, to assess probability outcomes stemming from sensed space activities and provide and/or determine appropriate responses. It includes multiple communication capabilities to notify a receiver of detected anomalous activity in a space, provision of recommended response activities, and the activation of preventive measures, including the engagement of the automatic fire-fighting activity.
In all the circumstances of the prior art that the present invention seeks to overcome, the methodology for the detection and identification of anomalous activity in a space has been solely performed by the employment of sensors, including cameras, either actively monitored by an operator, or that trigger an operator intervention through the use of alarming. In most cases the identification of a fire and the activation of the fire-fighting response has been the triggering of an installed fixed fire suppression system via passive methods following the detection of an actual fire, or the sounding of an alarm following the detection and classification of a threat. Examples of these fire response methods are the increase in the temperature on a sprinkler head that causes a liquid in a glass bowl to shatter, and in doing so, to release the water into a space, in a wet system, or nitrogen in a dry system that then fills with water and sprinkles the area.
Other systems use a detector separate from the sprinkler head, that then causes the piping to the sprinkler head to fill with water and sprinkle the affected space. Other more integrated systems combine space sprinkling systems with dry chemical space suppression technologies, or clean agent extinguishing systems. Clean agent systems are designed to remove either the heat, the fuel source, or the oxygen from a fire. The most common agents for this purpose are inert gases, such as nitrogen, argon, or carbon dioxide, which remove the oxygen from the location of the fire; or FM-200 which is a gas that employs heat absorption to remove the heat element of a fire, or agents such as 3M Novec 1230, that is often used to suppress a fire with a colorless, non-toxic fluid that does not damage sensitive electronic equipment.
Each agent employed has advantages and disadvantages. The most general disadvantage is the application method utilized, which is typically the employment of a whole space flooding approach to extinguishing the fire. More specific disadvantages are related to the tendency to apply a single agent to an entire space, combined with other items such as dissipation time for some gaseous agents, oxygen displacement hazards to personnel from inert gas agents, and the incompatibility between agents.
Therefore, an apparatus and method according to the present invention, of pre-emptively detecting an anomalous activity, and specifically activities or events that lead to an active fire event, including a means of conducting pre-emptive deterrence, and active threat response, specifically for fire events, is needed. In the case of a fire event, the active threat response required is able to specifically target the exact location and cause of a fire, classify the type of fire, and respond with the most advantageous extinguishing agent that minimizes the amount of collateral damage to equipment and materials in the area of the fire, notify an operator, and take pre-emptive actions to limit the spread or growth of the fire, until additional response activities can be brought to bear.
Accordingly, it is an objective of the present invention to provide a system and methods for autonomous space monitoring, characterization, and situational evaluation, specifically directed to pre-emptive and event driven autonomous therapies including firefighting activities utilizing robotically controlled firefighting equipment, sensor packages, autonomous selection and release of firefighting agent, and the autonomous detection, classification, and location of existing and impending fire events and other threat events.

It is an objective of the present invention to locate the fire, or threat in 3-D space.
It is an objective of the present invention to employ threat prediction, evaluation, assessment, and incident response actions, and probabilities of success employing those actions utilizing advanced software programs such as artificial intelligence methodologies, and to report those predictions, evaluations, assessments and incident response actions with probabilities of success to a supervisory system and or operator.

It is an object of the present invention to know the pressures of the firefighting agents left in the storage reservoir to make adjustments as nozzle pressure decreases to maintain firefighting agent stream delivered to the location of the fire event.
It is another object of the present invention to provide a communication link to notify a fire department or other responding agent of the activation of the fire-fighting response, with detailed information on the type of agent selected, the classification of the type of fire, the time of activation, the current status of the fire, and any other information on the character of the fire as determined by the sensor package.

This facilitates the supervisory computer and operator interface with coordinating operations of each of the pre-existing system and the new subsystems. It also allows the system to provide communications regarding each of the pre-existing system and the new subsystems to the designated reporting authority, such as an operator.
A further embodiment of the invention is an autonomous continuous fire-fighting system for monitoring and reacting to threat events within a designated space, the designated space having precious cargo and a designated reporting authority. This autonomous continuous fire-fighting system has an agent delivery assembly with a nozzle module having a nozzle.

Characterizing the space may further involve the steps of: obtaining an item data set containing data regarding the sensitivity of items, and the potential threat of items within the space; populating an item database with the item data set; obtaining a firefighting equipment data set containing data regarding the firefighting equipment within the space; populating a firefighting equipment database with the firefighting equipment data set; obtaining a variable data set containing data regarding variables within the space which alter according to a time of day and an operational tempo; populating a variable database with the variable data set; obtaining a tolerance data set containing data of predetermined tolerance levels; populating a tolerance level database with predetermined tolerance levels; and creating the standard space characterization profile from each of the item database, the firefighting equipment database, the variable database, and the tolerance database.
The steps of assessing the new sensor data, and initiating preventative action, may further involve: assessing the new sensor data provided by the sensor assembly by comparing the space characterization profile with the new sensor data; comparing a degree of difference between the space characterization profile and the new sensor data with the predetermined tolerance level; and initiating preventative action if the degree of difference is greater than the predetermined tolerance level.
The step of assessing the new sensor data may further include: continuously analyzing the data by evaluating the data received to detect deviance from the space characterization profile; continually providing a probability of a hazardous activity based on the space characterization profile; continuously providing a hazard probability assessment by evaluating the potential deviance between the new sensor data from the space characterization profile with respect to the probability of that hazardous activity; and providing an assessment of a preferred incident response action by determining the best courses of response for any deviance detected.
The step of locating the threat event may further include comparing the location of the existing fire event with a first location of the first agent delivery assembly and a second location of the second agent delivery assembly.
The preferred embodiments of the present invention are illustrated in
Together this module and assembly make up the automated firefighting system 40 that provide the ability to perform space characterization, data analysis, anomaly detection, hazard probability assessment, profile deviance assessment, and incident response action, and autonomously predict, detect, classify, and respond to a threat including a fire or incipient fire event; and provide threat and fire type classification, and threat and fire-fighting status information to a supervisory system.
Note that while the system is designed to operate fully-automatically, the system includes the ability to be manually operated in all modes of operation if circumstances warrant operator intervention.
The control module 50 contains a sensor assembly 51, a processor module 52, a telerobotic position control module 53, an agent valve control module 54, a communication interface module 55, and an uninterruptible power supply battery 57. These are each discussed in greater detail below.
The sensor assembly 51 includes several sensor items, or any combination of sensors, including, but not limited to a flame sensor 51a, a thermal sensor 51b, combustible gas sensor 51c, photoelectric and/or ionization smoke sensor 51d, infrared spectrum or optical sensor 51e, image sensor/camera 51f, firefighting agent reservoir pressure sensor 51g, and a range sensor 51h.
The sensors included in the sensor assembly 51 are used to perform a number of functions, including, but not limited to:
The tasks performed by these sensors included in the sensor assembly 51 include, but are not limited to:
Essentially, the fire control module 50, contains a sensor assembly 51 that provides the sensory data required by the processor module 52, to perform program processing of algorithms 56a, 56b, 56c, 56d, 56e, 56f, 56g, 56h, 56i, 56j, 56k, 56l, 56m, 56n, 56o consisting of first characterizing the space, and subsequently identifying and assessing the risk potential of anomalous events, and subsequently to predict, detect, classify, and locate a threat and fire event in 3-d space, then to actively respond to the threat and fire event with the application of therapies, including firefighting agent to the location of a fire event, provide threat and fire event alert information to a supervisory system, and subsequently to evaluate the results of the active response efforts, and then, modify and control the active response as necessary as a function of the evaluation.
In the embodiment shown here, these sensors are portrayed as separate entities for ease of reference and clarity. However, in some embodiments, a single device acts as multiple sensors, performing the operation of more than one sensor. In some embodiments, video image data mining is employed for sensor data collection along with other sensors. A combination of video image mining and alternative sensor data collection is employed in yet other embodiments.
The processor module 52, interfaces to the sensor assembly 51, to the telerobotic position control module 53, the fire agent valve control module 54, and to the communication interface module 55.
The processor module 52 contains embedded software/firmware programs, 52a, that contain the machine learning and similar space characterization software, the artificial intelligence and similar decision-making subprocesses, which are facilitated by various algorithms, to analyze the information received from the sensor assembly 51, to predict, detect, localize, and determine the size, and type of fire or hazard 5, 6, 7, 8.
The processor module 52 also contains the control programs to position the pan and tilt drivers in the telerobotic position control module 53, to position the nozzle to the proper attitude necessary to place the fire agent onto the fire. It contains the control programs to open and close the valves using the agent valve control module 54, for the selection of the proper fire agent, and to open and close the valves on the fire agent bottles 64, in the fire-fighting activity.
In some embodiments, the processor module 52 also contains the messaging programs to the communication interface module 55, to report on the type, location, size, and status of the fire and the fire-fighting effort to a remote operator. It also contains the messaging programs to the communication interface module 55, to coordinate the synchronous operation of other telerobotic firefighting systems 20, in the fire-fighting effort, and to share information with other telerobotic firefighting systems 20 that may be useful in the fire-fighting effort (see for example,
The processor module 52 is loaded with a series of proprietary software algorithms 56a, 56b, 56c, 56d, 56e, 56f, 56g, 56h, 56i, 56j, 56k, 56l, 56m, 56n, 56o. Specifically, these algorithms include:
While different embodiments may employ a different number of sensors, regardless of the number of sensors employed, the processor module 52 receives the data from the sensors, and performs all the computational algorithms as necessary to:
As otherwise stated, the processor module 52 performs the following operations:
In summary then, the control module 52 receives continuous data from the sensor assembly 51, to assess the progress of the threat response action. In addition, the control module 52 provides continuous control commands to the telerobotic position control module 53, and the valve control module 54, to continue the threat response assessment and action to a successful conclusion. The processor module 52 also provides status and activity information to the communication module 55 for uploading to a supervisory computer system 80. Finally, the control module 52 also receives command information from a supervisory system 80 via the communication module 55, for manual operation of the system 40, as may be required.
The telerobotic position control module 53 is employed by the processor module 52 to drive the pan assembly 62 and the tilt (or azimuth) assembly 60 to properly position the nozzle 61, in the performance of the threat response to a threat, fire, or pre-threat or pre-fire event 5, 6, 7, 8.
The control module 50 is generally powered from local power. However, the control module 50 is also provided with an uninterruptible power supply 57 (such as a battery) which can provide emergency power in the case of an interruption of normal local power.
The valve control module 54, is utilized by the processor module 52 to select, open, and close the agent control valves 63a, 63b, 63c. In this manner, the processor module 52 can selectively control the release of a selected agent from a respective one of a series of firefighting agent bottles 64a, 64b, 64c. After selecting the selected agent, a respective one of the agent control valves 63a, 63b, 63c is opened so that the selected agent can travel via the appropriate hose 65 to the nozzle 61. A respective one of the agent sensors 69a, 69b, 69c is then instructed to provide agent reservoir pressure information, so that the valve control module 54 can evaluate the amount of selected response agent available.
If the remaining amount of selected response agent becomes insufficient to meet the remaining needs, a different agent may then be selected. The valve control module may in this way modify the selected agent as necessary to maintain agent on the threat or fire location. When the selected response agent is no longer needed or desired, the valve control module will then give instructions to close that selected valve.
A control cable assembly 66 connects the control module 50 to the delivery assembly 70. Specifically, in the embodiment illustrated in
The control cable assembly 66 may be a control wiring harness. One appropriate control wiring harness may be the Elkhart Brass RC10 Control Sensor Harness. The Elkhart Brass RC10 Control Handle Sensor Harness is a wiring harness designed to connect a sensor or switch to the Elkhart Brass RC10 Slow Closing Valve Control Handle. The harness allows the sensor or switch to communicate with the control handle, providing information on the status or position of the valve. The RC10 Control Handle Sensor Harness is typically used in applications where remote monitoring or automation of the valve is required. For example, in a fire protection system, a sensor could be installed to detect the presence of smoke or heat, triggering the valve to close automatically via the RC10 control handle. The sensor harness would transmit the signal from the sensor to the control handle, ensuring the valve closes quickly and safely.
The delivery assembly 70 has a nozzle module 72, and three agent modules 74. The nozzle module 72 includes a nozzle tilt assembly 60, a nozzle 61, a pan assembly 62, a manifold assembly 67, a camera 68, and a range sensor 71. Each agent module 74 has a firefighting agent valve 63, a firefighting agent bottles 64, a firefighting agent hose assembly 65, a control cable assembly 66, and a firefighting agent bottle pressure sensor 69. This embodiment has three agent modules 74, so the delivery assembly 70 as a whole has a series of firefighting agent valves 63a, 63b, 63c, a series of firefighting agent bottles 64a, 64b, 64c, a firefighting agent hose assembly 65, and a series of firefighting agent bottle pressure sensor 69a, 69b, 69c. 63, 63a, 63b, 63c,
In the preferred embodiment as illustrated in
The agent delivery assembly 70 provides position and range information for the nozzle assembly 61 to the control module 50. Once properly positioned, the agent control valves 63a, 63b, 63c receive commands from the valve control module 54 to open, providing a path for the selected agent to exit the agent bottles, 64a, 64b, 64c through the connecting piping 65 to the manifold 67, and from there to the nozzle assembly 61.
In the embodiment shown here, the camera 68 is mounted onto the pan assembly 60 and the tilt assembly 62. This enables the camera 68 to rotate with the nozzle 61, so that the field of view of the camera 68 changes with the field of spray of the nozzle 61.
The camera 68, along with the information from the sensor assembly 51, is used by the control module 50, to locate a threat, or impending threat event location, in 3D space. Then, the camera 68, again along with the information from the sensor assembly 51, provides visual and sensor feedback to the control module 50 that is utilized by the processor module 52, to assess the action of the agent on the threat and/or fire. While a camera 68 is shown here, it is to be understood that in other embodiments, this could be any comparable type of sensor, capable of providing sensor data, visual or otherwise, about the space in relationship to the agent delivery assembly for providing feedback to the control module 50 for evaluation.
In some embodiments, the camera 68 is not provided as part of the pan and tilt assembly 60, 62. Instead, cameras are only provided in the sensor package of 51e, 51f. In yet other assemblies, cameras 68 are provided as part of the pan and tilt assembly 60, 62, as well as being provided in the sensor package of 51e, 51f. This enables system 40 to have a firefighting nozzle 70 placed in a location where it is desirable to have a camera that can both pan and tilt. The sensor package 50 is intended to be fixed in a permanent location and located away from the nozzle to keep the view of the space clear. The sensor package 50 may or may not likewise be fixed onto a further pan and tilt assembly and therefore may or may not have a pan and tilt capability.
The firefighting agent hose assembly 65 may have one or more flexible hoses. Hoses appropriate for this might include those tested and listed for use with ANSUL® R-102 and PIRANHA Restaurant Fire Suppression Systems through Underwriters Laboratories (UL/ULC), and LPCB (Loss Prevention Certification Board). Typical hose diameter might be between 1 in. and ¼ in., and more typically about ½ in. (13 mm) and a length of between 10 ft and 0.5 ft, and more typically about 5 ft (1.5 m). For NPT/NPTF hose fittings, male NPT/NPTF swivels might be provided at hose ends for easy installation. NPSM swivel adapters may add versatility. May include 3 ft (0.9 m) long restraining cable, or other restraining cable hardware kit for various mounting options. Offers convenience of moving portion of delivery assembly for cleaning without disconnecting agent piping.
Each agent module 74 has a firefighting agent valve 63, a firefighting agent bottle 64, a firefighting agent hose assembly 65, and a firefighting agent bottle pressure sensor 69. This means that each of the series of fire agent control valves 63a, 63b, 63c, corresponds to a specific respective one of the series of firefighting agent bottles 64a, 64b, 64c. Likewise, each of the series of firefighting agent bottle pressure sensor 69a, 69b, 69c, corresponds to a specific respective one of the series of firefighting agent bottles 64a, 64b, 64c. Finally, each of the series of hoses 65a, 65b, 65c, corresponds to a specific respective one of the series of firefighting agent bottles 64a, 64b, 64c.
Although this embodiment shows only three firefighting agent containers 64a, 64b, 64c, it is to be understood that there could be any number of containers. In this embodiment each of the three firefighting agent containers are understood to contain a different type of firefighting agent. The processor module 52 identifies each of the types of agents contained, as well as the class of fire present, and uses the database of recognized hazards to identify and employ the correct agent for each class of fire. Using the incorrect agent can create additional hazards or allow the fire to re-ignite after apparently being extinguished successfully.
Information regarding possible firefighting agents contained within firefighting agent bottles 64 of the present invention are provided below. The firefighting agent bottles 64 may contain both a water and a foam agent. This agent extinguishes fire by taking away the heat element of the fire triangle. Foam also separates the oxygen element from the other elements. The processor module 52 recognizes the potential hazards, i.e., as the discharge stream could spread the flammable liquid in a class B fire or could create a shock hazard on a class C fire, and so recognizes that water and foam agents are preferred for class A fires.
Firefighting agent bottles 64 may contain carbon dioxide which extinguishes fire by taking away the oxygen element of the fire triangle and also be removing the heat with a very cold discharge. The processor module 52 recognizes that this agent is usually ineffective on class A fires, so recognizes that this agent is preferred for class B & C fires.
Dry chemical fire agents are also possibly contained in firefighting agent bottles 64. These agents extinguish the fire primarily by interrupting the chemical reaction of the fire triangle and creating a barrier between the oxygen element and the fuel element on class A fires. Multipurpose dry chemical agent is effective on class A, B, and C fires. Ordinary dry chemical is for class B & C fires only.
Firefighting agent bottles 64 may contain wet chemical agents that extinguish the fire by removing the heat of the fire triangle and prevents re-ignition by creating a barrier between the oxygen and fuel elements. Wet chemical agents are preferred for class K fires and may also be used on class A fires.
Halogenated or clean agent are also possibly contained in firefighting agent bottles 64. These agents include the halon agents as well as the newer and less ozone depleting halocarbon agents. They extinguish the fire by interrupting the chemical reaction of the fire triangle. Clean agents are primarily preferred for class B & C fires.
Firefighting agent bottles 64 may contain dry powder agents, which are similar to dry chemicals. However, dry powder agents work by separating the fuel from the oxygen element or by removing the heat element of the fire triangle. This means that dry powder agents are ineffective on most classes of fires, and preferred for class D or combustible metal fires, only.
The traditional firefighting agent, water mist, is also a possibility. Though the use of this agent in firefighting agent bottles 64 is new, water mist works by taking away the heat element of the fire triangle. This is an alternative to the clean agent extinguishers where contamination is a concern. Water mist agents are primarily for class A fires, although they are safe for use on class C fires as well.
Firefighting agent bottles 64 may contain cartridge operated dry chemical agents which extinguish the fire primarily by interrupting the chemical reaction of the fire triangle. Like the stored pressure dry chemical agents, the multipurpose dry chemical is effective on class A, B, and C fires. This agent also works by creating a barrier between the oxygen element and the fuel element on class A fires.
Agents that are ABC rated means that the chemical agent inside of it will work on ordinary combustibles, flammable liquids, and objects which are electrically energized. Other chemical agents that would not work on ordinary combustibles (wood, paper, cloth) are less “corrosive” than that of the ABC agent and often better suited for a marine application in an emergency.
In some embodiments, the range determination sensor 71 is incorporated into the function of the camera. Using a subprocess to gather location data pinpointing two locations: the location of the nozzle and location of the sensor package. These locations can be utilized to determine the range from the nozzle to the location of a fire in the space.
In this embodiment, a range detector 71 is mounted on the nozzle pan 62 and nozzle tilt 60 assemblies. The range detector 71, as well as the camera 68 mounted on the nozzle pan 62 and nozzle tilt 60 assemblies, as well as the information from the sensor assembly 51, provides information to the processor module 52 to determine the range (or distance) to a location of a threat, fire event, potential fire event, or other anomaly detected.
Ships 10 often have multiple spaces 12a, 12b, 12c, 12d, 12e, 12f, 12g.
As before, this embodiment has a range detector 71 and camera 68 mounted on a nozzle assembly 61. The nozzle assembly 61 in turn is mounted on a pan assembly 62, and a tilt assembly 61. In alternative embodiments, this may be a combined pan and tilt assembly. Each of these: the nozzle pan assembly 62, the nozzle tilt assembly 61, the camera 68, and the range detector 71, provides information to the processor module 52 of the fire control module 50 to determine the range to a location of a threat, fire event, potential fire event, or other anomaly detected.
As before, the tele-robotic firefighting nozzle agent delivery assembly 70 provides image, position, and range information for the nozzle assembly 61 to the fire control module 50. Once properly positioned, the agent control valve 63 receives commands from the valve control module 54 to open. Once opened, control valve 63 provides a path for the selected firefighting agent to exit the fire agent bottles 64 through the connecting piping 65 to the nozzle assembly 61. However, in this embodiment, because there is only a single firefighting agent bottle 64, there is no need for a manifold 67, and there are a reduced number of hoses 65a, 65b, 65c in the overall hose assembly 65.
Each subsystem 40′ may have a further supervisory computer and operator interface 80′. Each further supervisory computer and operator interface 80′ may have a further three control modules 50 communicating with each other and with the further supervisory computer and operator interface 80′. With each of the further three control modules 50′ connected and communicating with further agent delivery assemblies 70′.
The supervisory computer and operator interface 80 according to the present invention is capable of interacting with each of the subsystems 20, 40′ and facilitates communication with each of the pre-existing system subcomponents 22, 24, 26 with the new subsystems 40′. In order to facilitate this, the associated data of each of the multiple subcomponents 22, 24, 26 of the pre-existing system 20 must be identified, categorized, and integrated into the present system methodology assessments.
While this figure illustrates one supervisory computer and operator interface 80, and a single pre-existing system 20, it is to be understood that any number of supervisory computer and operator interfaces can be communicated to and with each other, and any number of pre-existing systems and pre-existing subcomponents.
As graphically illustrated, in this embodiment, different distances (20 ft, 30 ft) exist between the supervisory computer and operator interface 80 and the control module 50 and the pre-existing system 20. This enables system 40 to have various control modules 50 placed in position for optimal sensor collection, while the delivery assembly 70 is placed in the optimal position for distribution of firefighting agents—to best compliment the pre-existing system weak points. The supervisory computer and operator interface 80 is thus capable of interacting with each of the subsystems and facilitates communication with each of the pre-existing system subcomponents.
This system 40 shows multiple subsystems 40′ fully integrated and incorporated, with a subsystem 40′ for larger spaces in space 12d. A subsystem 40′ is provided in contained smaller spaces 12a, 12b. A subsystem 40′ is provided for overcoming occlusions in a first part of space 12c. Each of these subsystems 40′ are hardline connected to the supervisory computer and operator interface 80. A temporary subsystem 40′ is capable of being moved about the ship 10 from a first space 12f to a second space 12c. The temporary subsystem 40′ is capable of connecting and communicating with the supervisory computer via Bluetooth or other communications array provided in control module 50. The supervisory computer and operator interface 80 is thus capable of interacting with each of the subsystems and facilitates communication with each of the pre-existing system subcomponents.
Of course, the apparatus and method 40 according to the present invention, has the increased advantage of being able to pre-emptively detect an anomalous activity, which may otherwise lead to an active fire event, and employing a means of conducting pre-emptive deterrence, thereby avoiding the hazards 5, 7 shown in
If hazards 5, 7 were to develop into full fire events, the active threat response analysis is able to specifically target the exact locations with respect to the space within 12a, 12d and relative causes of the fire (hazards 5, 7). The active threat response then classifies the type of fire and responds with the most advantageous extinguishing agent that minimizes the amount of collateral damage to equipment and materials 1, 2, 3, 4 in the areas of the fire. The system is also capable of notifying an operator and taking pre-emptive actions to limit the spread or growth of the fire 5, 7 until additional response activities can be brought to bear (if necessary).
Further details regarding the method of operation of the present invention are discussed with particular reference to
Additional steps performed by the inventive method of the present system include anomaly assessment 120, threat assessment 130, threat location 140, threat classification 150, agent selection 160, nozzle positioning 170, valve assessment 180, delivery assessment 190, and finalization 200 (which could also include reinitialization). It is to be understood that while these are shown and discussed as occurring in a sequential order, many of these steps are actually occurring concurrently. Indeed the outcome from many of these steps are coincidently employed by other steps of the methodology in a reiterative and recursive process.
Before the method of the present invention can be initialized, 110, the system components must first be present.
Moving on to
The processor module 52 then determines whether to proceed with the automated process 117 or to turn over control 114 to a manual operator. The method 100 begins the process to turn over control to a manual operator 114 by initiating manual control 220. Then the processor module 52 receives and sends control commands 222 to nozzle position controller subprocess, and agent valve controller subprocess.
Most often, the system will continue to operate automatically 117 and will proceed to characterize the space 118 and then to assess any potential anomalies 120. Regardless, each of these options are discussed in greater detail below.
When manual operation is initiated 220, the processor module 52 receives a manual tilt command 220. The processor module 52 sends the tilt command to the nozzle position controller subprocess, which is facilitated by the algorithm 56f. The processor module 52 receives a manual pan command 220. The processor module 52 sends the pan command to the nozzle position controller subprocess, which is facilitated by the algorithm 56f. The processor module 52 receives a manual agent valve command. The processor module 52 sends the agent valve command to the agent valve controller subprocess, which is facilitated by the algorithm 56e.
The processor module 52 loads the data provided from the space characterization database 58p in part of the initialization process 110. However, space characterization 118 is a subprocess of the present inventive method by itself. The processor module 52 characterizes the space for the inventive system for normal operation in various operating conditions using inputs from the sensor assembly 51 and the space characterization algorithm 56j.
This subprocess continuously employs the space characterization algorithm 56j to locate the position of the agent delivery assembly 70 and the sensor assembly 51 in the space, along with various items of significant equipment. The space characterization algorithm 56j utilizes information provided from a space characterization database which can also include information obtained from space drawings and manufacturers data and entered into the space characterization database by an operator.
The space characterization database 58p will have the positions of the agent delivery assembly 70 and the sensor assembly 51 in the space, and significant items of equipment in the space. As part of the space characterization step, the processor module 52 assigns a risk factor to the equipment related to its potential as a source of fire, and the classification of the class type of potential fire likely to be associated with the equipment. For example, if there is a significant amount of electrical equipment, an electrical fire (Class C) might be more likely. Whereas in an area with a significant amount of solvents, fuels, or cleaning fluids, a Class B type of fire might be more likely. In a space with multiple types of potential hazards, there might be multiple types of likely hazards 5, 6, 7, 8.
The space characterization subprocess, which is facilitated by the algorithm 56j, is used to characterize the space by recognizing fixed items in the space, as may be identified by radio frequency identification (RFID) tags, by camera image recognition, by manual input, or other means. The space characterization subprocess, which is facilitated by the algorithm 56j, additionally performs the computations to define nominal space characteristics for 1 or more operating conditions. The space characterization algorithm employs machine learning and other software programs to accomplish the characterization functions. This information is utilized by the processor module 52 to improve the fidelity of locating and characterizing a detected fire event in the space, and in assisting in computing the agent range and targeting subprocess, which is facilitated by the algorithm 56g.
Data entries of the table are entered by an external operation and provided to the processor module as a populated database table. Each equipment item id location is provided a location that is referenced to an established space datum point. Each equipment id is assigned a primary fire threat classification type that specifies the likely type of fire threat the equipment id represents. Each equipment id is assigned a secondary fire threat classification type that specifies the second likely type of fire threat the equipment id represents.
The space characterization database subprocess identifies the firefighting equipment in the space and identifies each sensor assembly 51 id number and the location of the sensor assembly 51 in the space in relationship to the datum point. The space characterization database subprocess identifies telerobotic fire nozzle assembly 61 id number and the location of the fire nozzle assembly 61 in the space in relationship to the datum point. The space characterization database subprocess stores images of the space that are classified according to an operational tempo and time of day database. These tables are loaded 118b into processor module 52 memory for use in further processing functions.
If an action is indicated, the processor module 52 initiates the process to determine the preventive action indicated and notifies the supervisory computer utilizing the communication algorithm 56l.
The communication algorithm 56l is used by the processor module 52 to assemble and format outgoing messages to the supervisory computer, and to interpret received messages from the supervisory computer. The processor module 52 continuously analyzes the data received from the sensor assembly 51 using the data analysis, anomaly detection, hazard probability assessment, and profile deviance assessment and incident response action algorithm, 56k.
If there are differences identified between the two sets of images, then the process determines the degree of difference. This degree of difference is then compared to a predetermined tolerance level. If the degree of difference does not exceed the predetermined tolerance level then the process simply reinitiates and continues the reiterative process of determining the degrees of difference, comparing the difference with the tolerance levels, and then determining if the degree of difference exceeds the predetermined tolerance level. If the degree of difference ever exceeds the predetermined tolerance level then the data is sent on to be further evaluated by the threat and fire classification subprocess, and then sent on to the communications subprocess.
The fire prediction subprocess of the processor module 52 continuously monitors and assesses conditions relative to a probable fire event.

The processor module 52 loads the data from the data message 212 into format a message. The processor module 52 loads the formatted message to the communication buffer. The processor module 52 sends the formatted message to the supervisory computer 80.

The processor module 52 processes the data received from multiple sources to determine the probability of fire or threat, facilitated by the threat and fire detection algorithm 56a. Note that while the present invention description sometimes differentiates between an impending threat event, an impending fire event, an existing threat event, and an existing fire event, the term threat event is also used generally to refer generally to each of these, and is distinguished only by circumstances from when the event is a nonthreat event, aka, the sensor picked up an event that was neither a threat, nor a fire, and is thus disregarded by the anomaly assessment subprocess 130.

The processor module 52 loads the threat and fire classification subprocess 150 to determine the type of threat and or the class of fire detected. The processor module 52 processes the threat and fire classification algorithm 56b if the threat and fire detection algorithm 56a detects an event. The threat and fire classification algorithm 56b is employed by the processor module 52 which receives input from the infrared spectrum sensors 51e, and the camera sensors 51f, and the camera 68, to determine the type of threat or fire event. This threat and fire classification algorithm 56b will also use information from the threat and fire location algorithm 56c, and the space characterization algorithm 56j to aid in this classification.
As an example, if a fire event is detected, and the information from the threat and fire location algorithm 56c locates the fire in the area surrounding an electrical switchboard, the threat and fire classification algorithm 56b will use this information along with information from the infrared spectrum sensors 51e, and the camera sensors 51f and camera 68 in classifying the type of fire, and to determine the probability the fire event is a Class C (electrical) fire. This information will be employed by the processor module 52 to determine which agent to utilize in the threat response action.
It is noted that the US classification schema is adhered to in this description so that the other classification categories include: Class A (combustibles); Class B (flammable gases and liquids, fuels); Class C (electrical); Class D (combustible metals); and Class K (cooking oils).
