DETAILED DESCRIPTION OF THE INVENTION
The invention comprises a communication method, comprising the steps of: sending a communication from a sender; routing the communication to a receiver through a routing method selector, the routing method selector routing the communication through a member of a set of communication methods based upon cost; and receiving the communication. Optionally the communication method is used for updating a location of a wildfire with the communication(s), such as via multiple firefighters and/or field deployable firefighting position indicators updating a fire location in graphical software based application. Optional message passers optionally relay the communication, such as in remote areas with poor communications.
For clarity of presentation and without loss of generality, the graphical communication link is described using a wildfire fighting/suppression example. More particularly, the invention is described as a system facilitating resource identification and resource communication using a command and control communication system, such as used in firefighting. However, generally the graphical communication link apparatus, system, and/or method of use relates to establishing communication using a graphical selection method between two or more communicators. The established communication is optionally and preferably supplemented with a local representation of the environment, such as terrain, natural resources, available man-made resources, identification of teams, weather, visibility, and/or competing elements.
In one example, a method and apparatus is used to establish a communication link via selection of a graphic of a person or group overlaid on a map, such as via use of a communication aircraft or satellite without timely knowledge by a caller of the called person's or group's identity and/or phone number. Communication is aided by personal communicators worn and/or carried by the caller and person or group called. The established communication is optionally and preferably supplemented with a local representation of the environment, such as terrain, natural resources, available man-made resources, identification of teams, weather, visibility, and/or competing elements. The communication link is optionally integrated into a firefighting command and control system, a friend network, a company group, and/or for a team so time is not spent looking up a phone number.
In yet another embodiment, an integrated and distributed wildfire fighting system is used in gathering information related to firefighting resources, developing a strategic plan, and/or communicating directions to and/or between resources. Communicators linked to positions of natural resources, personnel, and/or equipment are used to communicate identification, position, capability, and/or status of individual resources to a main controller via satellite and/or aircraft. The communicators additionally facilitate communication between personnel, teams of personnel, levels in a firefighting hierarchy, and/or with automated equipment. Further, drop ball communicators are used to transmit localized information, such as weather, a fire-retardant drop request, and/or a call for emergency aid to nearby resources, an aircraft, and/or to a main controller.
In another embodiment, a controller is used to communicate information, such as a plan and/or information about a first resource, to another resource, such as a firefighter. Several non-limiting examples are provided to further clarify the first embodiment. In a first example, information on a large number of resources is gathered by a controller and subsequently subsets of the gathered information are distributed to one or more groups, such as to a chief, manager, leader, strike team, and/or individual firefighter. In a second example, individual resources are provided with a corresponding individual identifier and/or a corresponding individual communicator, where the individual communicator communicates status and/or capability of the individual resource to additional local resources, to a local controller, and/or to the main controller using a local communication link, via an aircraft, and/or via a satellite. In a third example, a group of resources is provided with a corresponding group identifier and/or a corresponding group communicator, where the group communicator communicates status and/or capability of the group to the main controller, to a higher level of a hierarchy, to a lower level of a hierarchy, and/or to a second localized group. In a fourth example, any permutation and/or combination of elements of the wild land fire resource organization and/or distribution of the wildfire resources described herein is optionally used.
In still another embodiment, a drop locator, also referred to as a drop ball, is used to communicate a position, a fire status, a need level, and/or a vector related to a local setting to a controller, such as via aircraft communication and/or via satellite communication.
In yet another embodiment, an integrated and distributed wildfire fighting system is used in gathering information related to firefighting resources, developing a strategic plan, and/or communicating directions to and/or between resources. Communicators linked to positions of natural resources, personnel, and/or equipment are used to communicate identification, position, capability, and/or status of individual resources to a main controller via satellite and/or aircraft. The communicators additionally facilitate communication between personnel, teams of personnel, levels in a firefighting hierarchy, and/or with automated equipment. Further, drop ball communicators are used to transmit localized information, such as weather, a fire-retardant drop request, and/or a call for emergency aid to nearby resources, an aircraft, and/or to a main controller.
Herein, firefighting command and control is the exercise of authority and/or direction by a properly designated leader, such as an incident commander, over assigned firefighting resources in the process and accomplishment of wildfire suppression and/or wildfire control.
Referring now and throughout to FIG. 1, a wildfire fighting system 100, such as an integrated and distributed command and control firefighting communication system is described. In the wildfire fighting system 100, a controller, such as a main controller 110 or local controller, gathers resource information 112 and distributes the resource information 112. Herein, resource information 112 includes:
- (1) any location information 120 related to a fire, such as a coordinate on a map 121, information about localized weather 123, such as wind speed or weather radar information; information on a high value structure 125; information about a local water source 127; and/or information about on a firebreak 129;
- (2) any information related to personnel 200 used to fight the fire; and/or
- (3) any information related to equipment 300 used to fight the fire.
Information about one or more resource and/or directions to the one or more resource is optionally and preferably communicated to a receiving resource via an airborne communication system, vehicle, satellite, and/or spacecraft. Herein, for clarity of presentation and without loss of generality, a satellite 130, such as a low earth orbiting satellite, is used to refer to the communication medium, such as a helicopter, airplane, communication balloon, and/or communication satellite. Further, wireless communication 132, for clarity of presentation and without loss of generality, between the main controller 110 and a resource and/or between two or more resources is used to refer to any electromagnetic signal sent through the atmosphere, such as a radio-wave. Elements of the wildfire fighting system 100 are further described, infra.
Still referring to FIG. 1, in one embodiment the wildfire fighting system 100 is an analog or species of the Distributed Common Ground System—Army (DCGS-A) used by the military, for command and control of the military, where the wildfire fighting system is used to facilitate communication of the resource information 112 and/or firefighting plan between the main controller 110 and a receiving resource. However, the wildfire fighting system 100 uses a different wavelength, encryption method, software package, authority, personnel, and/or satellite than the DCGS-A system. In one example, one or more existing military satellites are used in the wildfire fighting system 100. In a second example, a dedicated satellite and/or a dedicated subsystem of a satellite is used in the wildfire fighting system 100.
Communication System
Still referring to FIG. 1, the main controller 110/satellite 130 communication of the wildfire system 100 is optionally a cloud-type interface for sending and/or receiving resource information 112, such as information about personnel 200 and/or information about equipment 300. For example, the personnel 200 and/or the equipment 300 optionally transmit position, such as a global positioning system (GPS) position obtained with a global positioning system receiver, plan, and/or status to the main controller 110 via the satellite 130. Similarly, the main controller 110 and satellite 130 are optionally used to transmit instructions to one or more of the personnel 200 and/or to one or more pieces of the equipment 300. Communication between elements of the wildfire fighting system 100 is further described, infra.
Still referring to FIG. 1, the location information 120, information about the personnel 200, and/or information about the equipment 300 is communicated to the main controller 110. In a first example, a map 121, such as a local terrain map, is provided to the main controller 110. In a second example, weather 123, such as local rainfall, wind, and/or cloud cover is provided to the main controller 110. In a third example, information about a high value structure 125, such as a house, bridge, historical site, and/or a utility is provided to the main controller 110. In a fourth example, location of a local water source 127, and/or information about a firebreak 129 is provided to the main controller 110. In a fifth example, information about the personnel 200 is provided to the main controller 110. In one case, the main controller 110 is maintained with pre-existing information about the personnel 200. For instance, the name, rank, home organization, experience, specific training associated with each individual is optionally pre-loaded in the main controller 110 and/or sent via a communicator 400, described infra, to the main controller 110, such as via the satellite 130. In a second case, dynamic information about the personnel 200, such as current position and/or status is provided to the main controller 110. Optionally and preferably the dynamic information is provided to the main controller 110 using the wildfire fighting system 110. More particularly, optionally and preferably continuous, periodic, and/or on demand personnel activated status and/or position of one or more of the personnel 200 is provided to the main controller 110 via communication passed to and relayed by the satellite 130. In a sixth example, information about the equipment 300 is provided to the main controller 110, where the information about the equipment 300 is generic to the equipment 300, such as a capability of the equipment 300, and/or is dynamic equipment information about the status and/or location of the equipment 300. The status/location of the equipment is optionally sent via an uplink to the satellite 130 and relayed to the main controller 110 on a continuous, periodic, and/or on an as needed basis. Generally, information deemed pertinent to fighting a wildfire is provided to the controller. The provided information is received by the controller directly, through use of a database, and/or via use of a communication system.
Still referring to FIG. 1, the controller or main controller 110 is optionally any hardware/software package used by at least one member of the personnel 200, such as a commander, in strategic and/or tactical distribution and control of the personnel 200 and/or the equipment 300. The main controller 110 is optionally and preferably a full-sized computer equipped with one or more display screens. The display(s) are optionally configured with computer code implemented options to: view terrain, view a fire perimeter, view all or any subset of the personnel 200, view all or any subset of the equipment 300, view all or any subset of the location information 120, view local and/or regional weather, view any resource or subset thereof contained with the main controller, allow multiple command center access points to simultaneously view specialty subset information for a given operator, equipped with zoom functions, is linked to other command centers, and/or is equipped with communication links to a higher level authority and/or to any of the personnel 200 and/or to any automated equipment, such as a firefighting drone or robot. Additionally, the main controller 110 facilitates communication related to fires on private land to state and/or federal authorities, such as the National Interagency Fire Center (NIFC).
Still referring to FIG. 1, information and/or instructions are communicated from the main controller 110 to the personnel 200 and/or to the equipment 300 or vise-versa, such as via the wireless communication 132, via an aircraft, and/or via the satellite 130. In a first example, local information related to the map 121, the weather 123, the high value structure 125, the water source 127, and/or the firebreak 129 is provided to one or more of the personnel 200 via the satellite 130. In a second example, information about a first resource is communicated to a second resource using the main controller 110, the wireless communication 132, and the satellite 130. In one case, the location information 120 is provided to the personnel 200. In a second case, information about the equipment 300 is provided to the personnel 200. In a third case, information about a first sub-group of the personnel 200 is provided to a second sub-group of the personnel 200. Generally, any element known to the main controller 110, any of the location information 120, any information about member of the personnel 200, and/or any information about an element of the equipment 300 is optionally and preferably communicated with any other element of the main controller 110, member of the personnel 200, and/or element of the equipment 300 via the satellite 130 and/or via an aircraft.
Personnel
Referring now to FIG. 2, the personnel 200 are further described. Optionally and preferably the personnel 200 are organized in a hierarchical structure, such as through 2, 3, 4, 5 or more levels including an incident commander 210, an operations chief 220, a division manager 230, a branch manager 240, a task force leader 250, a strike team 260, and/or a firefighter 270, each level optionally containing many people. Additional levels in the hierarchy and/or fewer levels in the hierarchy are optionally used, such as dependent upon a size of a given wildfire. Any of the personnel 200 optionally communicate with the main controller 110 via the satellite 130 or aircraft or vise-versa. Further, any member or group of the personnel 200 optionally communicate directly with any other member or group of the personnel 200 via the satellite 130 or aircraft.
Equipment
Referring now to FIG. 3, the equipment 300 is further described. Generally, the equipment 300 includes any physical item used by at least one member of the personnel 200. However, for clarity of presentation and without loss of generality multiple examples of the equipment are provided in FIG. 3, including an engine 310; a tender/tanker 320; heavy equipment 330, such as a bulldozer; a command center 340; an emergency system 350; and/or a drop ball 360. The drop ball 360 is further described infra. The drop ball 360 is optionally of any geometry and is optionally referred to as a drop block. Optionally and preferably, any element of the equipment 300, such as a the drop block, dozer, and/or drone, is configured with a communicator that communicates an identifier, a position, and/or a status of the member of the equipment 300 to the main controller 110, to one or more members of the personnel 200, and/or to another member of the equipment 300, such as an automated member of the equipment 300, via the satellite 130. Optionally a drone aircraft is equipped with an environmental sensor, such as for sensing any of wind speed/direction, visibility, and temperature for use by a weather model, such as sent via the main controller 110.
Communicator
Referring now to FIG. 4, a communicator 400 is illustrated. Any member of the personnel 200 and/or any element of the equipment 300 is optionally equipped with an individual communicator. Similarly, any group of members of the personnel 200 and/or any group of elements of the equipment 300 are optionally equipped with a group communicator. For clarity of presentation, individual communicators and group communicators are referred to herein as a communicator. The communicator 400 is any means of communicating identity, location, and/or status of the personnel 200/equipment 300 to the satellite 130 for relaying to the main controller 110 and/or to another communicator. The communicator 400 is configured to send a unique identifier address and position information associated with each resource to the main controller and/or to filed deployed tablets, such as via the satellite 130. Each communicator is optionally equipped with any feature of a smart phone, such as voice, text, and/or graphics communication. Each communicator is optionally configured with a satellite uplink system and/or a satellite communications receiver.
Still referring to FIG. 4, an example of the communicator 400 is provided. Optionally, the communicator 400 contains an emergency activation element 410, such as an emergency activation switch/button. The emergency activation element is linked to at least one of a beacon 412, such as a flashing light, and a transceiver 420 used to communicate with the satellite 130 and/or an aircraft 131. The transceiver optionally and preferably sends to the satellite information about the personnel 200 contained in memory 430, a GPS 440 location of a member of the personnel associated with a given communicator, and/or any information entered by a member of the personnel 200 via an input/output system 450 to the communicator. For instance, a firefighter 270 optionally indicates distress and/or need of rescue to the main controller 110 by activating the emergency activation element 410. Optionally, the firefighter 270 enters additional information via the input/output system 450, such as need level. An optional central processing unit (CPU) 460 and power supply 470 are optionally electrically linked to any of the aforementioned elements of the communicator 400.
Still referring to FIG. 4, the communicator 400 is optionally in the form of a tablet. For example, the input/output system is optionally of a touch screen form factor the size of a cell phone, phablet, or tablet intended to be carried and/or worn by the firefighter, such as on a forearm or wrist. In this example, the communicator is optionally configured with a screen showing surrounding terrain, weather, smoke, personnel 200, and/or equipment 300 where dynamic fire-related elements displayed on the screen are provided to the communicator by the main controller 110 via the satellite 130 on a continual, periodic, and/or on demand basis. In this manner, a first firefighter may see his/her position relative to other firefighters, the personnel 200, the equipment 300, and/or the location information 120.
Still referring to FIG. 4, the communicator 400 is optionally and preferably water resistant, waterproof, shock resistant, and/or ruggedized for field deployment.
Still referring to FIG. 4, an example of use of the communicator 400 by a firefighter 270 is provided. After the firefighter 270 activates the emergency activation element 410, the communicator sends information to the main controller 110 via the satellite 130. Optionally and preferably, the main controller 110 provides an audible and/or visual alert to a user of the main controller 110 of the received distress signal. The main controller 110 automatically and/or at the control of a user of the main controller 110 relays the distress signal and associated information, such as number of personnel affected and GPS site, to a rescue team, such as a nearby strike team 260, aircraft 121, and/or outside search and rescue team. Optionally, the distress signal is sent with priority directly to one or more nearby support units by the communicator 400. Optionally, a response from the main controller 110 is provided to the firefighter 270, such as what resources are dispatched, estimated time of arrival of the dispatched resources, capabilities of the dispatched resources, location of arrival of the dispatched resources, and/or instructions to the firefighter 270, such as a direction to move, a coordinate to move to, and/or a lifesaving strategy.
Still referring to FIG. 4, the communicator 400 optionally operates passively without interaction of the personnel 200. For example, a given communicator 400 periodically and/or on demand sends to the main controller 110 identity information, skills/capabilities, and/or location of the personnel 200 or equipment 300 associated with the given communicator. Accordingly, the main controller is continually updated with position/status of the personnel 200 and/or equipment 300 in the field, in reserve, or even in route from a remote area.
Still referring to FIG. 4, the communicator 400 is optionally configured with text/voice capabilities. For example, the display screen of the communicator 450 showing nearby resources is optionally coded to allow a visual distinction between personnel types in the hierarchy. For example, a firefighter 270 might appear in blue, a strike team encircled by a graphical perimeter, and/or a task force leader in red. One firefighter 270 may optionally select another firefighter by touching the communicator icon representing the second firefighter and either call the second firefighter or message (voice or text) the second firefighter through a connection established using the satellite 130 or aircraft 131. Similarly, the second firefighter receiving the call or message optionally observes on the second firefighter's communicator a graphical representation of the caller on his/her communicator, which is optionally overlaid with the tactical situation, such as smoke, terrain, and/or other resources. In this way, a first leader or commander may call/contact a second leader or commander based upon position without necessarily knowing the second leader or commander's name or phone number by merely selecting the icon on the touch screen of the communicator. Further, the two personnel in contact know where each other are relative to the terrain and/or resources displayed on their individual communicator, which facilitates ease, speed, and accuracy of communication in a time critical firefighting scenario. Generally, any firefighter 270 or any personnel 200 may contact in this manner any other firefighter 270 or personnel 200. The software optionally allows groups of personnel to be simultaneously contacted, such as all members of a strike team, all leaders, and/or all managers. Notably, since each communicator 400 is optionally and preferably individually coded, communications optionally occur simultaneously without being interrupted by other conversations as is the case with existing VHF and/or radio communications. Further, optionally a first firefighter can enter directions or draw on a first communicator and the graphically entered plan is transferred to a second communicator, or any number of communicating communicators, where the first firefighters drawing, sketch, entered line, and/or symbol appears on the communicating communicators after being relayed via the VHF, aircraft, and/or satellite system. The ability to draw on the map of the local terrain and have other firefighters observe the drawing on their communicators facilitates communication and/or action in the field.
Still referring to FIG. 4, the communicator 400 is optionally installed using a quick connect/disconnect system. In one case, a magnet is used to connect the communicator to each piece of equipment. In a second case, the communicator 400 is integrated into each piece of equipment. In a third case, the communicator 400 is a wearable item. However, in a preferred case, a docking station is installed on each potential piece of equipment and the communicator is attached to the docking station or docking port when deployed. Upon mobilizing equipment at a standard check-in to a fire incident, the communicator 400 is attached to the docking port by ground-support. Upon demobilizing from the incident, each vehicle or piece of equipment goes through a standard vehicle inspection prior to being let go from the incident. At this demobilizing inspection, the ground support mechanic optionally recovers the GPS transceiver device from the vehicle and secures the device for use in the next fire incident.
Still referring to FIG. 4, the communicator 400 is optionally used to track progress of fighting a wildfire, referred to in the art as bread crumb trails. For example, historical information on position of a dozer, with or without status of use of a blade of the dozer, are provided by a communicator attached to the dozer allows a firebreak path to be established. This allows the commander at a glance to make sure that dozers are not directed to a previously developed path. Similarly, progress of a strike team is optionally recorded and shared with progress of another strike team to ensure that efforts are coordinated, such as forming a single perimeter as opposed to parallel paths.
Still referring to FIG. 4, the communicator 400 is optionally used to locate an individual even in the event of a battery and/or transceiver failure by recording a history of location signals; using the signals to learn a last know path and/or last known vector; and/or by using a software option to immediately retrieving/displaying to the commander, rescue personnel, and/or the firefighter in need a rescue a last direction from the main controller 110 and/or last communication(s) to the main controller 110. The battery itself is preferably backup up, such as with standard AA batteries. Further, one or more support vehicles is optionally configured with a battery charging/battery swap system.
Still referring to FIG. 4, the wildfire fighting system 100 is optionally used in conjunction with a traditional VHF system. For instance, communications between personnel 200 is optionally line-of-sight communication. The communicator 400 is optionally configured to first try to establish a line-of-sight communication between personnel 200. In the event of inability to communicate directly or in the event of poor reception quality, the communicator 400 is optionally configured with software that automatically or manually switched to communication via the satellite 120 and/or the aircraft 121.
Location Information
Referring now to FIG. 5, the location information 120 sent and/or relayed to the main controller 110 is further described.
In a first example, information about the water source 127 is further described. The water source 127 is optionally a natural dip site 412, such as: (1) a known lake dip site or (2) an identified dip site, such as a deep area of a river. The firefighter 270 optionally relays information on the natural dip site 412 to the main controller 110 via the satellite 130 using the wildfire fighting system 100.
Optionally, the firefighter 270 marks a discovered or located natural dip site location with a drop ball 360. The drop ball 360, described in additional detail infra, optionally sends a GPS location of the natural dip site 412 to the main controller 110 via the satellite 130 and the main controller 110 relays the natural dip site GPS location to a helicopter for refilling a water container for later deployment on the fire.
In a second example, information about the water source 127 is further described. The water source is optionally a created dip site 414. For instance, the main controller 110 contains and/or is provided information on a hydrant and/or pump location 416, dispatches equipment 300, such as a dozer and/or pump to the pump location 416, personnel 200 to create and fill a water basin using the dozer, and dispatches the newly created dip site location 414 to additional personnel 200, such as a helicopter crew for water refilling a bucket carrying helicopter or helitanker.
In a third example, information about the firebreak 129 is further described. Information on one or more firebreaks 129 is optionally maintained in the main controller 110 or is supplied to the main controller 110 as a firebreak 129 is created in the field. More particularly, the type 422, direction 424, and/or condition 426 of a firebreak 129 is communicated to the main controller 110. For instance, firebreak type 129 is natural, such as a ridge or river; maintained; a burned out area; or temporary. For the natural river firebreak or the temporary firebreak, the condition 426 of the break, such as river width or percent construction completed, is optionally and preferably relayed to the main controller 110.
Generally, location information 120 includes location and/or status information of non-personnel information and non-equipment information.
Drop Ball
Referring now to FIG. 6A and FIG. 6B, the drop ball 360 is further described. The drop ball 360 is any portable/deployable device positioned by any member of the personnel 200 used to relay information about a location to the aircraft 121, satellite 130, and/or main controller 110 for use in firefighting tactics. Optionally and preferably, the drop ball 360 weighs less than 1, 2, 4, 8, or 16 pounds and is designed to be carried by a firefighter to a deployment site or dropped by a helicopter or drone at the deployment site. For clarity of presentation and without loss of generality, four examples are provided prior to detailing options of the drop ball 360. In a first example, the drop ball 360 is positioned by a firefighter 270 where the firefighter 270 wants an aircraft 121 to drop a fire retardant. The drop ball 270 directly and/or indirectly provides the aircraft 121 with drop zone information. In a second example, the drop ball 360 is positioned by a firefighter 270 by a dip site, such as a natural dip site 412 or a created dip site 414. Again, the drop ball, directly or indirectly, provides an aircraft 121, such as a bucket carrying helicopter with a location and/or status of a dip site. In a third example, the drop ball 360 marks an emergency extraction location. In a fourth example, the drop ball 360 marks a resource distribution location. In a fifth example, a connect-the-dot line is marked with a set of 2, 4, 8, 16, 32, 64, or more drop balls to form a requested firebreak line and to communicate the firebreak line to the main controller. The drop ball 360 is further described, infra.
Still referring to FIG. 6A and FIG. 6B, the drop ball 360 is of any geometric size and/or shape. As illustrated in FIG. 6A, the drop ball is a unit with a flat side, such as a side contacting the ground during use. As illustrated in FIG. 6B, the drop ball 360 optionally has at least one rounded surface 364 and/or is composed of two or more separated units.
Still referring to FIG. 6A and FIG. 6B, the drop ball 360 communicates: (1) with the main controller 110 via the satellite 120 and via the main controller 110 to any of the personnel 200 and/or resources 300 and/or (2) directly with nearby personnel 200. The drop ball 360 is optionally equipped with any element of the communicator 400, such as a drop ball: transceiver, memory, GPS, input/output system, CPU, power supply, and/or emergency activation element. However, the drop ball 360 is designed to be left by the firefighter 270 at a site, whereas the communicator 400 is designed to be worn: (1) by the personnel, such as on a belt, in a backpack, or within a helmet of the firefighter, or attached to the equipment 300, such as an engine 310, tanker 320, or a piece of heavy equipment. Preferably, the drop ball 360 has one or more operator controls 362, described infra.
Still referring to FIG. 6A and FIG. 6B, the operator controls 362 of the drop ball 360 are further described. The operator controls 362 optionally include any of: (1) an activation switch used to initiate operation of at least a transmitter of the drop ball 360 or to shut off the drop ball 360; (2) a personnel selectable switch, such as selector to program the drop ball 360 to transmit a signal indicating presence of: (a) a dip site, (b) a drop zone, and (c) an emergency pickup site; (3) a magnitude selector for indicating any of: (a) magnitude of a fire, (b) size of a dip site, (c) need for extraction; and/or (4) a vector selector for indicating direction and/or length of a fire retardant drop. Optionally, means for firefighter input to the drop ball 360 include use of a computer interface, such as a touch screen, a voice control, a keyboard entry, and/or a graphical user interface input.
Still referring to FIG. 6A and FIG. 6B, the drop ball is optionally a single unit, such as illustrated in FIG. 6A or a multi-piece unit, such as illustrated in FIG. 6B. Indicating direction of a fire retardant drop requires the firefighter 270 deploying the drop ball 360 to take time to orientate relative to a map and/or a compass. Hence, the drop ball 360 optionally includes a base unit 364 and a direction unit 366, optionally tethered by a length indicator 368. In use, the base unit 364 is deployed and the firefighter indicates direction of drop by positioning the direction unit 366 away from the base unit 364 in a direction. In this case, both the base unit 364 and the direction unit 366 send to the main controller 110 or aircraft 121 the unit type, base or direction, and GPS location allowing a crew of the aircraft or a fire retardant drone to know a start position and direction of a fire retardant drop. Optionally, the length indicator 368 is marked with a scale to indicate a desired magnitude of the drop and/or a desired length of a vector of a drop of the fire retardant. Again, the markings on the length indicator 368, which optionally unwinds from a coil during use, allows the firefighter 270 to provide location, magnitude, and/or vector of a desired drop of flame retardant without spending undo time in the field proximate a fire. As illustrated in FIG. 6B, the base unit 364 is optionally the shape of a ball; has an element intended to resist movement on the ground, such as an anchor shape; has a ground gripping element, such as a rough surface; and/or is labeled base and the direction unit 366 is optionally in the shape of an arrow and/or is labeled direction for immediate recognition by a well-trained fire fighter and/or recollection by a novice fire fighter. Generally, any element of the communicator 400 or the operator controls 362 are optionally integrated into any element of the multi-element drop ball.
Still referring to FIG. 6A and FIG. 6B, the drop ball 360 is optionally equipped with one or more sensors, where data from the one or more sensors is sent to the main controller 110, such as via the satellite 130. For example, the drop ball 360 optionally contains a temperature sensor, a wind speed sensor, a wind direction sensor, and/or a hygrometer. Relaying the sensor data to the main controller 110 allows localized input to a weather model and/or accurate timing/tracking of a front of a fire. For example, when a fire passes over the drop ball, the temperature sensor would see a spike in temperature, which is optionally automatically relayed to the main controller 110 along with a GPS coordinate and/or time. Thus, a set of drop balls 360 yields input data to tracking movement of a fire through wild land. In another example, wind speed, wind direction, and/or water moisture readings from the sensors is relayed to the main controller 110, such as for use in fire tracking and/or as inputs to a local weather map, where the local inputs provide highly valuable real time localized input to weather tracking/prediction models, which is in turn useful to the personnel 200 in fighting a wild fire.
Communication Routing
Referring now to FIGS. 7-13 a communication system, such as for firefighters, the military, the government, and/or the public is described. Referring now to FIG. 7, a communication routing system 700 is illustrated. In one process, a call is placed 710. Subsequently, a routing method selector 830 routes the call, such as via a least cost routing selector 831, to a receiver, that receives the call 730. Optionally, the routing method selector 830 routes that call based on quality/clarity 832 of the link and/or speed of connecting 833 the link.
Referring now to FIG. 8, a least cost routing selection method 800 is illustrated, such as a method implementing the least cost routing selector 831. Generally, a calling device 715, such as a phone, drop block, and/or drop ball 360, is equipped with UHF, cellular, satellite, and/or land mobile radio. As illustrated, the placed call 710 is optionally a sender 810, such as a first person, group, or unit and/or is optionally a sensor 820, such as in the drop ball 360. Similarly, the received call 730 is optionally a receiver 840, such as a second person, and/or a program, such as in the cloud 850. The routing method selector 830 routes the call based on a preference, which is optionally selectable by the user, such as least cost, clarity, or connection speed. The routing method selector 830 optionally and preferably routes that call through a choice of communication means and/or a set of communication methods, such as via UHF 832, cellular 834, satellite 130, and/or land mobile radio (LMR) 836. Herein, UHF 832 is in a range of 300 MHz to 3 GHZ, such as 900 MHZ. Herein, LMR 836 is 25-50 MHZ, 138-174 MHZ, 406-420 MHZ, 450-512 MHz, and/or in 800 MHz & 900 MHZ (929 MHz) bands. In one example, the calling device 715 makes, the a receiving device 735, a least expensive call preferably using the least expensive UHF 832, then the more expensive cellular 834 if needed, and finally chooses the satellite 130 when the other call mediums are not available. Any device, when offline, optionally records an intended communication. When the device is again online, the communication is optionally automatically sent again with a new time stamp and optionally the original time stamp of the unsent communication(s). Optionally, any of the devices described herein, such as a firefighter application, maintains a database, such as local geology and/or equipment and automatically sends out chirps of current location, such as every 1, 5, or 15 minutes and receives chirps from other users, such as location and/or status. Any communication described herein is optionally encrypted.
Referring now to FIG. 9 a message passer system 900 is illustrated, where at least one message passer 720 acts as an intermediary between the placed call 710 and the received call 730, described supra. As illustrated, a least cost routing 835, such as determined by the routing method selector 830, is used to link the call from the caller to a message passer 720, between message passers, and/or from the message passer 720 to a receiver. Multiple message passers and multiple differing communication linkages between message passers and/or between the caller and receiver are further described, infra.
Referring now to FIG. 10, a multi-routing method and multi-passer system, 1000 is illustrated to link the sender 810 to the receiver 840/end user. As illustrated, a message is sent along a sent message path 1010 from the sender 810 to the receiver 840. Similarly, a return message path 1020 links the receiver 840 to the sender 810. Notably, the sent message path 1010 optionally differs from the return message path 1020, as further described infra.
Example I
Still referring to FIG. 10, an example of the sent message path 1010 is provided. Generally, a set of communication linkages 1030 are used to pass a message to/from the sender 810 and the receiver 840. As illustrated, a first communication linkage 1031, in this case UHF, is used/selected by the routing method selector 830 to route the message from the sender 810 to a first message passer 722. Similarly, a second communication linkage 1031, of the communication linkages 1030, in this case cellular, is used/selected by the routing method selector 830 to route the message from the first message passer 722 to a second message passer 724. As illustrated, the message continues from the second message passer 724 to the third message passer 726 using a third communication linkage 1033, in this case satellite, and from the third message passer 726 to the receiver 840, such as via a fourth communication linkage 1034. The return message path 1020 uses the same, similar, or differing message passers and/or communication linkages, as further described in a second example.
Example II
Still referring to FIG. 10, an example of the return message path 1020 is provided. Generally, the set of communication linkages 1030 are used to pass a message to/from the receiver 840 and the sender 810. As illustrated, a first communication linkage 1035, in this case cellular, is used/selected by the routing method selector 830 to route the message from the receiver to the third message passer 726 or a new first return message passer. Similarly, a sixth communication linkage 1036, of the communication linkages 1030, in this case UHF, is used/selected by the routing method selector 830 to route the message from the third message passer 726 to the second message passer 724 (which is optionally from a first return message passer to a second return message passer). As illustrated, the message continues from the second message passer 724 to the first message passer 722 using a seventh communication linkage 1037, in this case satellite, and from the first message passer 722 to the sender 810, such as via an eighth communication linkage 1038. Again, the routing method selector 830 optionally selects any member of the set of communication linkages 1030 to carry a message from any message passer to any other message passer, such as determined by cost, connection time, and/or transmission quality, as described supra. As messages are passed from user to user, transmitting power from the original sender is reduced as power, such as battery power, is only required to send the original communication. Communication from device to device is optionally communication from International Mobile Equipment Identity (IMEI) number to number. Optionally, one or more of the devices are assigned unique short alphanumeric identifiers, in place of IMEI numbers, to reduce airtime, transmission power, and bandwidth times, such as when communicating through a satellite.
Example III
Referring now to FIG. 11, a third example is used to further describe the multi-routing method and multi-passer system 1000. In this example, the sent message path 1010 is further described between n users 1110, such as an nth user 1112, an n+1 user 1114, and an n+2 user 1116, where n is a positive integer greater than 1, 2, 3, 4, or 5. Here a user represents the sender, the receiver, and/or any one or more of the message passers, described infra. As illustrated, the routing method selector 830 makes a first routing method selection to carry the communication from the nth user 1112 to the n+1 user 1114 and optionally makes a second routing method selection to carry the communication from the n+1 user 1114 to the n+2 user 1116. Similarly, the routing method selector 830 makes a third routing method selection to carry the communication from the n+2 user 1116 to the n+1 user 1114 and optionally makes a fourth routing method selection to carry the communication from the n+1 user 1114 to the nth user 1111. The number of intermediary users, or message passers, is any positive number n. A first number of intermediary users and/or message passers in a sent message direction is optionally more or less than a second number of intermediary users and/or message passers in a return message direction.
FIG. 12 illustrates that the routing method selector 830 optionally and preferably picks any intermediary carrying system, such as UHF 832, cellular 834, and/or satellite 130, to carry the message between any number of users and/or message carriers.
Common Message Area
Referring now to FIG. 13, the communication systems, described supra, are optionally used to update a common area 1310, such as an application in the cloud 1312, on one or more servers 1314, and/or in an application 1316. The common area 1310 optionally includes messages and/or graphics with the ability of many, optionally in a restricted manner, users to update the material, such as a fire area in a firefighting zone.
Still referring to FIG. 13, the sender 810 optionally communicates with a set of users 1110, such as n users, at once through at least one and preferably two routes, where n is a positive integer of greater than 1, 2, 3, 4, or 5. First, the sender 810 sends to the routing method selector 830 a communication. The routing method selector 830 routes the communication to the n users. As above, the routing method selector 830 optionally communicates with each of the n users through a least costly method and/or a fastest method. For instance, the routing selector optionally communicates with a first user 1111 and a second user 1113, of the set of users 1110, through UHF and communicates with a third user 1115 via satellite. Second, the sender 810 communicates the communication to the common area 1310. One or more of the set of users 1110 also communicate with the common area 1310 either directly and/or though another application of the routing method selector 830. Redundant messages are possible with the dual communication; however, many mechanisms allow for only one of the messages to be sent/displayed, such as a simple parity bit identifying an already received communication. Each member of the set of users 1110, such as the first user 1111 is optionally another sender at a common or a second period of time. In this manner, each of the users/senders can update the common area, such as the application at any time. For instance, any firefighter can update a map of a current fire at any time and each of the other user/firefighters receive the update through more than one route in a communication manner available to each firefighter, as further described supra.
Communication in Firefighting
Referring now to FIGS. 14, 15A, and 15B, use of the above described communication system in the application of firefighting is described.
Example I
Referring now to FIG. 14, circuitous communication 1400 between a first firefighter 271 and a second firefighter 272 is illustrated, with an intervening obstacle to communication, such as a mountain 1420, ravine, and/or dense smoke. As illustrated, the firefighters 270 optionally communicate around the mountain through a set of message passers, as described supra. In this case, the message passers are a set of vehicles 1440, such as a first vehicle 1442, a second vehicle 1444, and a third vehicle 1446. Each vehicle and/or a user therein has configured their vehicle and/or personal communication device, to function as a message passer. Optionally and preferably, the message passer is any system set up for passing the messages, as described supra, where the message passer is optionally not even dynamically aware that a message is being passed between the sender and the receiver (the first firefighter 271 and the second firefighter 272), but may have set up a preference to be a message passer as needed. As illustrated, a communication from the first firefighter 271 is sent via a first relay 1432 to the first vehicle 1442; from the first vehicle 1442 to the second vehicle 1444 via a second relay 1434; from the second vehicle 1444 to the third vehicle 1446 via a third relay 1436; and from the fourth vehicle 1446 to the second firefighter 272 via a fourth relay. Here the vehicle are examples of message passers and/or users as describe supra. Here, the first firefighter 271 is an example of a sender as described supra and the second firefighter 272 is an example of a cloud recipient, other users, and/or the common area 1310, such as the application 1316. In this manner and/or a similar manner, a group or groups of firefighters communicate with one another and/or with a common application through local hikers, passing cars, drop blocks, or any communication device configured to relay communications for the firefighters.
Example II
Referring now to FIG. 15A, an example of a firefighter application 1500 is illustrated. The firefighter application 1500 includes a screen 1510 of a firefighter communication device with optional links to multiple screens, such as through a menu 1540. In this example, firefighters 270 each have a quick display of a fire region, which is optionally zoomable/scrollable to each firefighter's specific location or nearby locations, such as support vehicles/equipment 300, a command center, roads 1515, water tanks, and/or anything of interest to a firefighter. In this example, contour lines 1520 are illustrated, such as a first contour line 1522 and a second contour line 1524, which aids a skilled firefighter in understanding a future path of a fire. Additionally, a current best position of a front/lead of a wildfire 1530 is illustrated along with an optional historical position of the fire 1532, such as less than or about 0.25, 0.5, 1, 2, 3, 4 or more hours ago. Also illustrated are drop balls 360, such as a first drop ball 361 and a second drop ball 363, which optionally transmit information, such as by any of the mean presented herein, such as: wind direction, wind speed, and/or humidity. One firefighter is optionally and preferably able to call another firefighter and/or resource, such as the bulldozer, through touch screen calling, such as by merely selecting an icon representing a receiver. Referring now to FIG. 15B, an optional message area 1570 and digital keyboard 1580 accessible through the menu 1520 are illustrated.
Example III
Still referring to FIG. 15A, the firefighter application 1500 is optionally and preferably linked to any of the communication systems described herein. For instance, a first firefighter 271 or group of firefighters is an optional sender 810 and/or user, such as a first user 1111, and a second firefighter or group of firefighters is an optional receiver 840 and/or user, such as a second user 1113. Each firefighter can optionally update a location of the first 1530, such as by touching the application screen 1510 and pulling the fire front to a new location. Similarly, the firefighter application is optionally and preferably able to sense a user dragging a finger and/or a stylus across the application, such as using a touchscreen, to update a current and/or a preferred fire retardant line 1534 position. Similarly, the drop ball 363, may optionally update a fire location, such as by sensing a large temperature increase, such as greater than 50, 100, 200, or 300 degrees fahrenheit, at the drop ball location at a known time. The application 1500 optionally uses keyhole markup language (KML) to display geographic data in an Earth browser, while optionally transmitting communication in Java script notation (JSON). Optionally, JSON is used with and/or in place of hypertext markup language (HTML).
Optionally drone data and drop sensor data are combined/concatenated/fused at the main controller 110.
Optionally, the main controller 110 communicates any and/or all of the collected information to a regional and/or national controller.
In addition to saving firefighter lives, the wildfire fighting system 100 will save state and federal tax dollars by decreasing injury probability and increasing efficiency of wild land firefighting. Further, the wildfire fighting system 100 will save state and federal dollars by phasing out very high frequency (VHF) radios and radio-repeaters, which have high equipment, setup, and maintenance costs. Still further, the wildfire fighting system 100 would eliminate the need of a lead aircraft to guide a fire retardant dropping airplane to a drop zone.
Still yet another embodiment includes any combination and/or permutation of any of the elements described herein.
Herein, a set of fixed numbers, such as 1, 2, 3, 4, 5, 10, or 20 optionally means at least any number in the set of fixed number and/or less than any number in the set of fixed numbers.
