Description

Technical Field

[0001] Embodiments of the present disclosure generally relate to systems and methods for managing and predicting power usage for ultraviolet (UV) lamps used for sterilization of structures and areas, etc. in environments such as the interior cabin of vehicles including commercial aircraft.

Background Art

[0002] Vehicles such as commercial aircraft are used to transport passengers between various regions. Currently, various systems for disinfecting or sterilizing the surfaces inside the aircraft have been developed, for example, there is a sterilization system using ultraviolet (UV) light.

[0003] However, the power available for use in the vehicle is limited. Vehicles such as commercial aircraft include many powered sub-systems, and a UV sterilization system will be additionally provided thereto. When the UV lamp operates at full capacity, it consumes a predetermined amount of power.

Summary of the Invention

[0004] There is a need for systems and methods for managing the power between the UV lamp and other powered sub-systems in a vehicle. Further, there is a need for systems and methods for efficiently and effectively allocating and predicting the power usage related to various powered sub-systems and the UV lamp in a vehicle.

[0017] The above-described outline of the invention and the details of the embodiments described later will be more clearly understood by referring to the accompanying drawings. Note that in this specification, elements or steps described in the singular form do not necessarily exclude multiple elements or steps. Furthermore, the reference to "one embodiment" is not intended to exclude the existence of other embodiments that incorporate the features described in that embodiment. In addition, unless otherwise specified, embodiments that "comprising" or "having" one or more elements in a particular state may additionally include other elements that are not in that state.

[0018] As described herein, embodiments of the present disclosure provide power management systems and methods for a given environment, such as the interior cabin of a vehicle. In at least one embodiment, a power forecasting and data management system and method for an ultraviolet (UV) subsystem including a UV lamp allows many UV light subsystems contained in the environment to adjust power distribution in accordance with power needs and / or demand. Embodiments of the present disclosure provide systems and methods for eliminating, minimizing, or at least reducing inappropriate, ineffective, and inefficient use of power supplied to UV light subsystems.

[0019] For example, there are times during a flight when it is not necessary to operate UV lamps at maximum capacity. For instance, during takeoff and landing, certain areas of the interior cabin are assumed to be unoccupied, and therefore, it is not necessary to operate the UV lamps in those areas at maximum capacity. To give a more specific example, the lavatory is assumed to be unoccupied during takeoff and landing. Therefore, UV disinfection is not necessary during that flight phase. However, even when surface sterilization is not necessary, the UV lamps installed in the lavatory continue to consume power. It is desirable that the power supplied to the UV lamps in this case be used for other equipment or subsystems of the aircraft.

[0020] FIG. 1 is a schematic block diagram of a power management system 100 for a vehicle 102 according to an embodiment of the present disclosure. This example shows use in a vehicle, but the power management system 100 system can be used in a variety of other environments, such as, for example, an enclosed space (a space in a residential or commercial building) or an outdoor facility (e.g., a stadium). For example, environments such as a vehicle, a building, or an outdoor stadium are provided with one or more ultraviolet (UV) light subsystems for sterilizing areas in the environment.

[0021] Environments such as the interior cabin 104 of the vehicle 102 include various areas 106. The interior cabin 104 includes, for example, a dressing room 106a, a galley 106b, a passenger area 106c (e.g., an area where passenger seats are provided), a control area 106d (e.g., a cockpit, a flight deck), and the like. The areas 106 included in the interior cabin 104 may be more or less than those shown in the figure.

[0022] One or more of the areas 106 include one or more UV light subsystems 108 configured to irradiate UV light for sterilizing various components and airflows in the area. Each UV light subsystem 108 includes a UV lamp 110 configured to irradiate UV light that sterilizes at least a portion of the corresponding area 106. The UV lamp 110 is configured to irradiate UV light in the far ultraviolet region, such as, for example, 222 nm. In other examples, the UV lamp 110 is configured to irradiate UV light in the UVC region, such as, for example, 254 nm.

[0023] In at least one embodiment, one area 106 can include a plurality of UV light subsystems 108. That is, each of the plurality of areas 106 can include one or more UV light subsystems 108. In other embodiments, the interior cabin 104 has only one area 106 that includes a plurality of UV light subsystems 108.

[0024] The UV lamp 110 can be fixed at a predetermined position. For example, the UV lamp 110 can be fixedly attached to a wall, ceiling, cabinet, etc. Optionally, the UV lamp 110 may be configured to be position - adjustable. For example, the UV lamp 110 can be attached to a structure so that its position can be adjusted by pivoting, rotating, moving a joint part, etc. In other embodiments, the UV lamp 110 can be configured as part of a portable device, for example, it can be included in a wand assembly connected to a backpack assembly, a case assembly, a cart assembly, etc.

[0025] The UV lamp 110 in the area 106 is connected to a power source 112. The power source 112 is a main power source or an auxiliary power source in an environment such as the interior cabin 104 of a vehicle. The power source 112 is, for example, an alternating current (AC) power source.

[0026] In at least one embodiment, the power source 112 is also connected to one or more other power - receiving subsystems 114 in the interior cabin 104. Examples of other power - receiving subsystems 114 include cooking appliances such as ovens, heating and cooling devices, audio / video systems (e.g., in - flight entertainment systems), power seats, etc. The power - receiving subsystems 114 can be distributed and arranged throughout the interior cabin 104, such as in various different areas 106.

[0027] The power management control unit 116 communicates with the power source 112 via, for example, one or more wired or wireless connections. The power management control unit 116 is configured to control the power source 112 (or control the output power of the power source 112) to supply power to the UV light subsystem 108 and the power - receiving subsystems 114 included in the interior cabin 104.

[0028] In at least one embodiment, the power management control unit 116 is configured to allocate power supplied from the power supply 112 to the UV light subsystem 108 based on power requests and / or demand. For example, each UV lamp 110 has a predetermined full-capacity power draw. The power management control unit 116 allocates the power supply to each UV lamp 110 between zero and the full-capacity power draw based on the power requests and / or demand of the UV lamps 110 at a particular time and in a particular area 106. For example, during one or more stages of a flight (e.g., takeoff or landing of a commercial aircraft), it is not necessary to operate the UV lamps 110 in a particular area 106, such as a restroom 106a, at maximum power. Therefore, the power management control unit 116 can reduce the power supply to the UV lamps 110 in the restroom 106a at a particular time as the power requests and / or demand for the UV lamps 110 in the restroom 106a decreases. This allows the power management control unit 116 to transfer the saved power (i.e., the reduced power to the UV lamp 110 in the restroom 106a) to other UV lamps 110 in other areas 106, such as the galley 106b, passenger area 106c, or cockpit area 106d, and / or to one or more other power receiving subsystems 114.

[0029] The power usage data 120 is, for example, information regarding power requests and / or demands of UV lamps 110 and power receiving subsystems 114 located in different areas 106, and can be stored in memory 118 by program. Memory 118 is included, for example, in a power management control unit 116. Optionally, the power management control unit 116 may be configured to communicate with memory 118 via one or more wired or wireless connections. In other embodiments, the power usage data 120 is transmitted from a data bus 122 of the vehicle 102 (e.g., an avionics data bus). For example, the power usage data 120 may include information regarding the current flight phase of a commercial aircraft, and information regarding power requests and / or demands of various UV lamps 110 and power receiving subsystems 114 during that flight phase. In at least one embodiment, the power management control unit 116 communicates with data bus 122 via one or more wired or wireless connections.

[0030] The power management control unit 116 adaptively controls (e.g., selectively allocate, distribute, or change) the power supply to the UV light subsystem 108 and / or the power receiving subsystem 114 based on the power usage data 120. In at least one embodiment, the power usage data 120 allows the power management control unit 116 to identify the power requirements of the UV light subsystem 108 and the power receiving subsystem 114 at any given time and in various regions 106, and to manage the power supply to the UV light subsystem 108 and the power receiving subsystem 114.

[0031] In at least one embodiment, one or more regions 106 include a motion sensor 124 that detects the presence of a person in the region 106. Examples of motion sensors 124 include light sensors (e.g., cameras, infrared sensors, etc.), weight sensors (e.g., electronic scales), heat sensors, and door lock sensors (e.g., sensors that detect the locking and unlocking of doors). The motion sensor 124 communicates with the power management control unit 116 via one or more wired or wireless connections. In at least one embodiment, the motion sensor 124 is a smart sensor. The motion sensor 124 communicates with the power management control unit 116 via one or more wired or wireless connections.

[0032] The power management control unit 116 receives a presence signal 126 output from the motion sensor 124. The presence signal 126 includes data indicating the presence status of people in area 106. Based on the presence signal 126 received from the motion sensor 124, the power management control unit 116 can determine whether people are present or absent in area 106 (for example, whether a particular area is unoccupied). The power management control unit 116 compares the presence status of people in area 106 with power usage data 120. For example, if an area 106 is unoccupied for a specific or predetermined period of time, the power management control unit 116 decides to reduce the power supply to the UV lamp 110 in that area 106 based on the power usage data 120.

[0033] It is not necessary to install motion sensors in all areas 106. In addition, it is possible to omit motion sensors from any area 106 at all. Alternatively, the power management control unit 116 does not need to be able to communicate with the motion sensor 124.

[0034] As described herein, the power management control unit 116 selectively and adaptively controls the amount of power supplied to the UV lamps 110 included in the UV light subsystems 108 of various regions 106 based on power usage data 120. The power usage data 120 includes information indicating the power requests and / or demands of the UV lamps 110 in various regions 106 at specific times. Specific times include, for example, a given flight phase and the occurrence of events requiring UV disinfection (such as the movement of people in region 106, or the detection of sneezing, coughing, or droplet dispersion in region 106). The power management control unit 116 distributes power to the UV lamps 110 (and optionally one or more power receiving subsystems 114) included in region 106 based on the power usage data 120 for each UV lamp 110 (and optionally, power receiving subsystem 114).

[0035] In at least one embodiment, the power management control unit 116 can transmit power management data 130 for various UV lamps 110 (and optionally the power receiving subsystem 114) over a predetermined time frame (e.g., one or more flights within a day, a week, or a month). Such power management data 130 may include information about different destinations (e.g., different airports) or flights at different times of the year.

[0036] The power management data 130 is received by a predictive power usage control unit 140 located away from the vehicle 102 (for example, at a central control station). Optionally, the predictive power usage control unit 140 may be mounted on the vehicle 102.

[0037] The predictive power usage control unit 140 can receive power management data 130 from various other vehicles in addition to vehicle 102. The predictive power usage control unit 140 can analyze the power management data 130 to identify locations and times where power requirements differ, such as different locations and times of the year. This allows the predictive power usage control unit 140 to refine the power usage data 120 for a particular flight to suit the destination and time of year. In other words, the predictive power usage control unit 140 can integrate power management data 130 from various vehicles and adjust or adapt the power usage data 120 to suit, for example, a specific flight or itinerary (if vehicle 102 is a train or bus).

[0038] As described herein, the power management system 100 in an environment such as the interior cabin 104 of a vehicle 102 includes a plurality of ultraviolet (UV) light subsystems 108 (each having at least one UV lamp 110) located in a plurality of different areas 106 of the interior cabin 104. A power management control unit 116 communicates with the plurality of UV light subsystems 108. The power management control unit 116 adaptively controls the power supply to the plurality of UV light subsystems 108 based on power usage data 120. The power supplied to the plurality of UV light subsystems 108 is variable. The power usage data 120 includes information on the adaptable power requirements for the plurality of UV light subsystems 108. For example, the adaptable power requirements include the amount of power required by the UV light subsystems 108 that changes over time.

[0039] In at least one embodiment, the power management control unit 116 supplies different amounts of power to at least two of the multiple UV light subsystems at a given time. For example, the power management control unit 116 adaptively controls the power supply to the multiple UV light subsystems 108 by reducing the power supply to a first system of the multiple UV light subsystems 108 and / or increasing the power supply to a second system of the multiple UV light subsystems 108.

[0040] In at least one embodiment, the power management control unit 116 communicates with a maintenance control unit via one or more wired or wireless connections. The maintenance control unit is configured to perform maintenance operations on the power management control unit 116. In other embodiments, the power management control unit 116 is configured to perform maintenance operations on the UV lamp 110 and / or the motion sensor 124, regardless of whether the maintenance control unit is configured to communicate with the power management control unit 116.

[0041] Figure 2 is a flowchart of a power management method in a given environment (e.g., the interior cabin of a vehicle) according to an embodiment of the present disclosure. Referring to Figures 1 and 2, the method first supplies power from a power supply 112 to UV lamps 110 located in different regions 106 in the environment 200.

[0042] In step 202, the power management control unit 116 determines whether the power demands of the UV lamps 110 in region 106 are different from each other. In at least one embodiment, the power management control unit 116 identifies different power demands from the power usage data 120. If there is no difference in power demand, the method returns to step 200, distributing the power supplied from the power source 112 equally to the UV lamps 110 (and / or the power receiving subsystem 114).

[0043] On the other hand, if it is determined in 202 that the power demands are different, the power management control unit 116 adjusts the amount of power supplied to the UV lamps 110 in 204 to match the respective power demands. By selectively and adaptively supplying power based on different power demands, power can be efficiently distributed among the UV lamps 110 in various regions 106.

[0044] In at least one arbitrary embodiment, the method proceeds from 204 to 206, in which step the power management control unit 116 outputs power management data 130 (representing the power management applied to each UV lamp 110 and / or power receiving subsystem 114 within a given time frame) to the predictive power usage control unit 140. In 208, the predictive power usage control unit 140 adjusts the power usage data 120 based on the power management data 130. Optionally, the method may omit steps 206 and 208.

[0045] As used herein, terms such as “control unit,” “central processing unit,” “unit,” “CPU,” and “computer” include any system based on a processor or microprocessor, such as a microcontroller, a reduced instruction set computer (RISC), an application-specific integrated circuit (ASIC), a system using logic circuits, and any other circuit or processor having hardware, software, or a combination thereof capable of performing the functions described herein. However, these are merely examples and do not limit the definition and / or meaning of such terms. For example, the power management control unit 116 and the predictive power usage control unit 140 may include one or more processors that control the operation of these units as described above.

[0046] The power management control unit 116 and the predictive power usage control unit 140 are configured to process data by executing a set of instructions stored in one or more data storage devices or elements (e.g., one or more memories). For example, the power management control unit 116 and the predictive power usage control unit 140 include one or more memories or are connected to one or more memories. If necessary, data or other information can also be stored in the data storage device. The data storage device may be in the form of an information source or a physical memory element included in the processor device. One or more data storage devices or elements may be volatile memory, non-volatile memory, or may include both volatile and non-volatile memory. For example, non-volatile memory includes read-only memory (ROM), programmable ROM (PROM), electrically writable ROM (EPROM), electrically erasable PROM (EEPROM), and / or flash memory. A volatile memory is random access memory (RAM) that functions as an external cache memory. In addition to the storage devices described above, any suitable type of memory is envisioned as the data storage unit of the system and method of this disclosure, but is not limited to the above-described storage unit.

[0047] A set of instructions may include a variety of commands that instruct the processor device, which functions as a power management control unit 116 and a predictive power usage control unit 140, to perform specific operations such as methods and processes according to various embodiments of the gist of this specification. Such a set of instructions may be in the form of a software program. Software programs can take various forms, such as system software or application software. Furthermore, software may be a collection of multiple individual programs, a subprogram included in a larger program, or a part of a program. Program modules based on object-oriented programming are also included in software. Processing of input data can be performed by the processor device in response to user commands, in response to the results of previous processing, or in response to requests from other processing machines.

[0048] The accompanying drawings illustrating embodiments show one or more control units or processing units, such as a power management control unit 116 and a predictive power usage control unit 140. Such processing units or control units represent circuits or parts thereof, which can be realized by associating instructions for performing the operations described herein (e.g., software stored in a tangible, non-temporary computer-readable storage medium, such as a computer hard drive, ROM, or RAM) with hardware. Such hardware also includes state mechanical circuits physically wired to perform the functions described herein. Optionally, such hardware may include one or more logic devices, such as a microprocessor, processor, or controller, or electronic circuits connected to such logic circuits. Optionally, the power management control unit 116 and the predictive power usage control unit 140 may be processing circuits, such as field-programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), and / or microprocessors. Circuits in various embodiments may be configured to execute one or more algorithms for performing the functions described herein. One or more of these algorithms, whether or not they are explicitly shown in the flowcharts or methods, may constitute several embodiments of the embodiments of this disclosure.

[0049] In this specification, the terms “software” and “firmware” are used synonymously and include any computer program stored in a data storage device (e.g., one or more memories) and executed by a computer. Examples of memory include RAM memory, ROM memory, EPROM memory, EEPROM memory, and non-volatile RAM (NVRAM) memory. However, the types of data storage devices mentioned above are merely examples and do not limit the types of memory that can be used to store computer programs.

[0050] As described herein, embodiments of this disclosure provide a system and method for dynamically controlling the power supply level to one or more UV light subsystems 108 contained in a vehicle 102 or other environment, based on various aspects contained in power usage data 120, such as human behavior, available power, load shedding, flight path data, aircraft status, and external factors. In other words, power usage data 120 contains information about such various aspects.

[0051] The UV light subsystem 108 can be installed in various locations within different areas 106 of the interior cabin 104. Areas 106 include restrooms, flight decks, cargo areas, crew rest areas, galleys, assembly areas, and passenger seating areas. As mentioned above, the available power in the interior cabin 104 is limited, so it may not be possible to operate multiple UV light subsystems 108 simultaneously at more than 100% power capacity.

[0052] Therefore, the power management control unit 116 is configured to control the power supply to the various UV light subsystems 108 based on the power demand (e.g., required for UV disinfection) and available power. In at least one embodiment, the power management control unit 116 manages the power supply to the UV light subsystems 108 based on power usage data 120, which may include information predicting when and how each individual UV light subsystem 108 will need power within a given time frame.

[0053] As a predictable aspect, power usage data 120 may include historical and predictive aircraft condition. For example, when the seatbelt sign is illuminated (e.g., during takeoff), UV disinfection of the lavatory 106a (and other shared passenger areas) is not required.

[0054] Another example is that the power usage data 120 may include information about a specific type of vehicle, such as a specific aircraft model. Since aircraft differ by model, and the load on an aircraft also differs between the ground and during flight, the power management control unit 116 can adaptively manage the power supply to the UV light subsystem 108 based on classifications and hierarchies such as location within the aircraft and available power. Information such as location within the aircraft and available power can be obtained from known or sensed data for each area 106.

[0055] In at least one embodiment, the power management control unit 116 can communicate with various other subsystems in the vehicle 102 (e.g., a lighting subsystem) via a data bus 122. Based on other power loads (e.g., if it is known or predicted that the microwave ovens in the galley 106b will be used simultaneously), the power management control unit 116 can predict when and how to control the power supply to the UV light subsystem 108 in order to distribute power to the UV light subsystem 108 more evenly. This prediction can be made dynamically based on external factors such as the status of an infectious disease outbreak, flight paths, and changes thereto. By utilizing such predictions, the power management control unit 116 can proactively control the UV light subsystem 108, for example, by controlling whether it is necessary to accelerate disinfection by the UV lamps 110 before reducing the power supply to those UV lamps in a particular area 106.

[0056] In at least one embodiment, the power management control unit 116, and / or other control units communicating with the power management control unit 116 via the data bus 122, can monitor the generator load of the vehicle 102. By monitoring the generator load, the power management control unit 116 can determine when power is supplied to and when power supply is interrupted to various subsystems of the vehicle 102. For example, one or more UV light subsystems 108 can use some or all of the remaining generator load before being released from the aircraft. Such use can be achieved, for example, by adjusting the power supplied to one or more UV light subsystems 108 that require all available power at a particular time (e.g., immediately after the crew has finished serving in-flight meals and drinks) to match the remaining generator load. The power management control unit 116 (or other control units communicating with the power management control unit 116) can predict the generator load and adjust the UV light subsystems 108 so as not to exceed the predicted generator load. This adjustment can be performed according to the hierarchical relationship of the UV light subsystem 108, where (for example, at a first point in time such as during cruising or after in-flight meal service) the UV light subsystem 108 of the lavatory 106a is positioned at the top of the hierarchy list, followed by the cabin, galley, crew rest area, flight deck, etc. This hierarchical relationship can be stored in memory 118 or included as part of the power usage data 120, and can be dynamically changed based on various factors such as flight conditions, route, time of day, and season. Furthermore, if there is a predictable correlation linked to the passage of time (e.g., lavatory use, galley use), control can be performed accordingly.

[0057] In at least one embodiment, the UV light subsystem 108 is configured to negotiate with the power management control unit 116. For example, the UV light subsystem 108 may include a control unit that negotiates with the power management control unit 116 regarding the power to be supplied based on known or predicted power loads. For example, all UV light subsystems 108 and power receiving subsystems 114 can communicate with each other via one or more wired or wireless connections. This allows these subsystems 108 and 114 to identify the power they need from each other and negotiate with the power management control unit 116 accordingly. For example, each subsystem 108 and 114 can negotiate by outputting signals regarding overall power need or a predetermined lower power backup request. The power management control unit 116 can evaluate the negotiation and allocate power based on the total available power, the order of requests, preferred areas, etc. Since the power management control unit 116 can predict when various loads and subsystems will be used, the power management control unit 116 can control the UV light subsystem 108 according to that prediction.

[0058] In at least one embodiment, the power usage data 120 includes a priority list for subsystems that require power and subsystems that do not. The priority list may be a pre-created, fixed list. Optionally, the priority list may be changeable over time. This allows the priority of non-essential subsystems to be changed based on predetermined conditions. For example, the power management control unit 116 can change the power supply priority list for various non-essential subsystems, such as a UV light subsystem 108, a cooking subsystem, and an entertainment subsystem located in different areas.

[0059] Depending on the specific UV light subsystem 108 and its installation location, the minimum power required at various times may be lower than at other times. Power usage data 120 can also include this information, and power can be allocated accordingly. For example, the UV lamp 110 can be operated with a power supply exceeding or falling below 100% of its preferred capacity, depending on the circumstances. For instance, such operation is possible when the power management control unit 116 detects that a person has entered or exited the restroom 106a via the motion sensor 124 and determines that the restroom 106a needs to be disinfected. In this way, the power management control unit 116 can quickly supply a large amount of power to the UV lamp 110 in the restroom 106a, taking into account the lamp's temperature limit or predicted temperature limit (in addition to known past usage), so that disinfection can be performed quickly before the next user arrives in the restroom 106a.

[0060] A light sensor located in region 106 can measure the UV light emitted by the UV lamp 110 and transmit the measured data to the power management control unit 116 and / or to other control units in the vehicle for analysis by an artificial intelligence / machine learning system. Such a system can analyze information such as delays, turn times, flight paths, and the use of the UV system during flight.

[0061] Predictive maintenance involves data from other aspects that can be obtained inside or outside the aircraft. The power management control unit 116 can analyze data on scheduled events to control the UV light subsystem 108 (and other power receiving subsystems 114), and can analyze any number of events, such as seat belt signs and meal service. For example, the power management control unit 116 can selectively operate and shut down the UV lamp 110 at high load after meal service (which can be identified, for example, based on oven use).

[0062] In general, the power management control unit 116 is configured to adaptively control the power supply to the UV light subsystem 108 and the power receiving subsystem 114 based on various aspects, characteristics, and predictions.
