Description

Intelligent ventilation control system and ventilation method thereof

[0001] The present invention relates to an intelligent ventilation control system and a ventilation method thereof that can intelligently perform ventilation and air purification in residential spaces, communal living spaces, etc.

[0002] Fine dust and ultrafine dust have recently become a serious problem. These fine dust particles are emitted into the atmosphere by various activities, including industrial activities, transportation, building combustion, and agriculture, and have a negative impact on human health. As the concentration of fine dust and ultrafine dust increases each year, people are limiting outdoor activities and spending more time indoors. Because indoor spaces are often enclosed and difficult to ventilate, the need to purify harmful substances and maintain clean indoor air quality is growing.

[0003] Until recently, indoor air quality management relied solely on air purifiers to address indoor and outdoor fine dust issues. While research and attempts to manage indoor air quality are ongoing, air purification is largely achieved through devices such as air purifiers, window-mounted ventilation systems, and fine dust screens. However, these products are mostly manually controlled, making them insufficient for indoor air purification when occupants are absent or inattentive. Furthermore, most systems rely on individual room monitoring, making them insufficient for comprehensive control of indoor air quality based on lifestyle patterns. Furthermore, while recently built apartment complexes are equipped with ventilation systems, these systems must be operated manually, and many apartment residents are unaware of their presence and often fail to utilize them effectively.

[0004] Therefore, research is needed on intelligent control technologies for each space, enabling automatic control without separate control commands, based on occupant patterns and regular monitoring of air pollutants. Furthermore, research is needed on coordinated control methods tailored to individual space air quality.

[0005] Meanwhile, various infectious diseases have recently been spreading through the respiratory system, significantly impacting society. While restrictions on outdoor activities and indoor self-quarantine are encouraged in the event of an outbreak, isolating family members within a single household is not realistically feasible. Therefore, securing separate negative pressure spaces within a single household is essential. Therefore, a system is needed to secure negative (or positive) pressure spaces as needed within a single family living space, thereby preventing the spread of infectious diseases among family members.

[0006] Accordingly, the problem that the present invention seeks to solve is to provide an intelligent ventilation control system for each space that can be automatically controlled without a separate control command, that is, without a separate manual operation or control by an occupant or user in an indoor residential space.

[0007] In addition, the goal is to provide an intelligent ventilation control system that can comprehensively consider the number of occupants, movement, and circumstances in indoor living spaces, and can control the air quality of individual spaces through regular monitoring.

[0008] Additionally, the goal is to provide an intelligent ventilation control system that can stably secure a separate negative pressure space within a household.

[0009] The tasks of the present invention are not limited to the technical tasks mentioned above, and other technical tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0010] According to an embodiment of the present invention for solving the above problem, an intelligent ventilation control system is provided, in an indoor residential space including multiple spaces, including an air exchange device including an air exhaust unit for collecting inside air in the indoor residential space and exhausting it to the outside, and an air supply unit for purifying outside air and introducing it into the indoor space, an exhaust unit including a first exhaust unit for exhausting air in a bathroom to the outside and a second exhaust unit for exhausting air in a kitchen to the outside, a plurality of diffusers arranged in a plurality of spaces for supplying air from the air exchange unit and introducing air into the indoor space or for sucking air from the indoor space and exhausting it to the outside through the air exchange unit, a motion sensor for detecting the location and movement of an occupant within the indoor residential space, and a control unit for controlling the amount of air movement in the air exchange unit, the exhaust unit, and the diffuser based on information from the motion sensor, wherein the control unit is characterized in that, when an occupant detected by the motion sensor reaches a specific first location and stays at the first location for more than a preset first time, the amount of ventilation at the first location is controlled to be further increased.

[0011] In addition, the control unit may be characterized in that, when the number of occupants detected from the motion sensor exceeds a first value range, the ventilation amount at the location of the occupants is controlled to be further increased, and when the number of occupants exceeds a second value range, which is a value for a specific number of people per unit area (㎡) set in advance, the ventilation amount at the location is controlled to be further increased.

[0012] In addition, the control unit may be characterized in that it stops the operation of the exhaust unit when a preset bedtime is reached and no movement is detected by the motion sensor at a specific location in the indoor living space for a preset second time period.

[0013] In addition, the control unit may be characterized in that it determines the time of entry of the occupant after going out through repeated learning, determines the time of entry every 24 hours, every week, or every month, and ventilates the indoor living space in advance three hours before the preset time based on the determined time of entry, and if the occupant does not enter the room at the time of entry, it may be characterized in that it inquires about the expected time of entry of the user into the indoor living space through the user mobile phone, and proceeds with re-ventilation based on the expected time of entry entered by the user through the user mobile phone.

[0014] In addition, the indoor living space may further include a window sensor unit that checks whether a window leading to the outside is open or closed, and the control unit may be characterized in that, when the window sensor unit detects that the window is open, the control unit controls the ventilation amount to increase as the distance from the window increases.

[0015] In addition, the indoor living space may further include a plurality of doors that open and close for each of a plurality of rooms in the room, and a door sensor unit that checks whether the doors are open and closed, and the control unit may increase the air intake amount of a first diffuser arranged in a specific first room according to a command input by an occupant to set the first room to a negative pressure that is relatively lower than other spaces, or increase the air supply amount of the first diffuser to set the first room to a positive pressure that is relatively higher than other spaces, and when the first door sensor unit of the first door arranged in the first room is open for a preset 4 hours or more, information about the fact that the first door is opened may be transmitted to a user terminal.

[0016] In addition, the control unit may receive power usage information located within the indoor living space, and, based on the power usage information, control to further increase the ventilation volume in a location with high power usage, and when power usage in the kitchen is detected, increase the air exhaust volume of the second exhaust unit at a higher rate than the degree of increasing the ventilation volume in other locations.

[0052] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0053] FIG. 1 is a schematic diagram showing an indoor living space according to one embodiment and the application of components of an intelligent ventilation control system according to one embodiment of the present invention to the indoor living space, and FIG. 2 is a schematic diagram showing an air exchange device according to one embodiment of the present invention. In addition, FIG. 3 is a schematic conceptual diagram showing an intelligent ventilation control system according to one embodiment of the present invention, and FIG. 4 is a schematic diagram showing the application of components of an intelligent ventilation control system according to one embodiment of the present invention.

[0054] Referring to FIGS. 1 to 4, an intelligent ventilation control system according to an embodiment of the present invention comprises an air exchange device (100) including an air discharge unit (110) for collecting internal air in an indoor living space and discharging it to the outside, and an air supply unit (120) for purifying external air and introducing it into the indoor space, an exhaust unit including a first exhaust unit (200) for discharging air from a bathroom (15) to the outside and a second exhaust unit (300) for discharging air from a kitchen (12) to the outside, a plurality of diffusers (401, 402, 403, 404, 405, 406, 411, 412, 421, 431) arranged in a plurality of spaces, for identifying the location and movement of an occupant within the indoor living space. The present invention comprises a motion sensor (451 to 481) and a control unit (600) for controlling the amount of air movement in the air exchange device (100), the exhaust unit (200, 300) and the diffuser (401, 402, 403, 404, 405, 406, 411, 412, 421, 431) based on information from the motion sensor (451 to 481), wherein the control unit (600) is characterized in that it controls to further increase the amount of ventilation in the first position when an occupant identified by the motion sensor (451 to 481) reaches a specific first position and stays in the first position for longer than a preset first time range.

[0055] The above air exchange device (100) includes an air discharge unit (110) that collects indoor air in an indoor living space and discharges it to the outside, and an air supply unit (120) that purifies the outside air and introduces it into the indoor space, and includes a heat exchange element (130) so as to purify polluted air when air is sucked in or exhausted between the indoor and outdoor spaces. In addition, although not separately illustrated, a dust collecting filter may be provided so as to purify polluted air when outside air is sucked in, or so as to purify polluted air when only inside air is circulated. Meanwhile, the air exchange device (100) may use various devices widely known in the art for exchanging air between the inside and outside of an indoor living space, or circulating indoor air. In addition, the air may be connected to these components by piping for the movement of air delivered from a diffuser or an exhaust unit, which are components for sucking and exhausting various types of air to be described later, or delivered to the diffuser or the exhaust unit. However, without limitation, the exhaust may be discharged to the outside by a separate external fan without being integrated into and connected to the air purification device.

[0056] Meanwhile, to control the intake and exhaust of each air, a blower fan or an outdoor fan can be combined to control the intake and exhaust volumes of each component, and these can operate in conjunction with a control unit. Furthermore, the blower fan or outdoor fan can control the airflow and ventilation volume by adjusting the power applied according to commands transmitted from the control unit.

[0057] The above exhaust unit includes a first exhaust unit (200) for discharging air from the bathroom (15) to the outside and a second exhaust unit (300) for discharging air from the kitchen (12) to the outside. Typically, an indoor living space includes a bathroom (15) and a kitchen (12). The first exhaust unit (200) disposed in the bathroom (15) may have a blower fan formed at a location adjacent to the indoor space of the bathroom (15) to discharge odors, moisture, etc. inside the bathroom, thereby facilitating smooth exhaust. In addition, a blower fan may be formed at a location adjacent to the space of the kitchen (12) to quickly remove smoke or food odors generated by cooking, thereby facilitating smooth exhaust. However, in the case of these exhaust units, the blower fan may rotate strongly, generating louder noise than a diffuser. The exhaust unit is primarily intended to discharge internal air to the outside and may, without limitation, form an air movement path separate from the air purification device (100). The first exhaust unit (200) and the second exhaust unit (3000) forming the exhaust unit of the present invention can operate in conjunction with the control unit (600) and can operate according to the spatial situation of the indoor living space measured by various sensors.

[0058] The plurality of diffusers (401, 402, 403, 404, 405, 406, 411, 412, 421, 431) may be spaced apart from each other in a plurality of spaces of an indoor living space to supply air from the air exchange device (100) to the room or to discharge air to the outside through the air exchange device (100). The plurality of diffusers (401, 402, 403, 404, 405, 406, 411, 412, 421, 431) may be formed by separate pipes to supply air provided from the air exchange device (100) to the room or to supply indoor air to the air exchange device (100) and exhaust it, but the present invention is not limited thereto, and may be formed by integrated pipes as needed. The above plurality of diffusers (401, 402, 403, 404, 405, 406, 411, 412, 421, 431) can control the ventilation amount by controlling the air movement amount of each of them by the control unit (600), and thereby the air purification of the space in which each of the plurality of diffusers (401, 402, 403, 404, 405, 406, 411, 412, 421, 431) is arranged can be performed differently.

[0059] The above motion sensors (451 to 481) can be placed at various locations in an indoor living space to detect the location and movement of an occupant within the indoor living space. For example, a plurality of the motion sensors can be placed adjacent to the locations where the diffusers (401, 402, 403, 404, 405, 406, 411, 412, 421, 431) are placed. Without limitation, the motion sensors can be formed integrally with the diffusers (401, 402, 403, 404, 405, 406, 411, 412, 421, 431). The above motion sensors (451 to 481) can detect the presence or absence of occupants, the number of occupants, and whether occupants are moving, and transmit the detected information to the control unit (600), so that the control unit (600) can detect the movements of occupants and control the ventilation amount.

[0060] The above control unit (600) can control the air movement of the air exchange device (100), the exhaust unit (200, 300), and the diffuser (401, 402, 403, 404, 405, 406, 411, 412, 421, 431) based on the information of the motion sensors (451 to 481), and for this purpose, can be linked with factors that control the air movement of each component. That is, it can control the air movement, ventilation amount, air purification amount, etc. by being linked with the blower fan, damper, outside fan, air exchange device, etc. that control the air movement amount, or the heat exchange element of the air exchange device. As described above, in order to control the air movement amount differently, the opening and closing of the damper, the opening degree, the rotation speed of each fan, etc. can be controlled.

[0061] Meanwhile, the control unit (600) is characterized in that, when an occupant detected by the motion sensor (451 to 481) reaches a specific first location and stays at the first location for longer than a first time period set in advance, the control unit (600) controls the ventilation amount at the first location to be increased. As described above, the motion sensors (451 to 481) are placed at various locations in an indoor living space and can detect whether an occupant exists, how many occupants there are, and whether the occupants are moving, and transmit the information to the control unit (600), and the control unit (600) can adjust the ventilation amount based on this. When an occupant reaches a specific first location and stays at the first location for longer than a first time period set in advance, the ventilation amount at the first location is considered to be relatively increased compared to other spaces, so that the ventilation amount can be controlled according to the location and behavior of the occupant.

[0062] For example, as shown in FIG. 4, when an occupant moves from bedroom 2 (14) to the living room (10), the motion sensor may not operate to control the ventilation volume in a space where the occupant stays for less than the first hour while moving. That is, when the occupant stays in the space for less than the first hour, the ventilation volume may not be controlled because the occupant is simply moving. On the other hand, when the occupant stays in the living room (10) for more than a specific first hour, the control unit (600) may predict that the occupant will stay in the living room (10) for a long time and may control the ventilation volume of the living room (10) to be relatively larger. In other words, if the occupant is watching TV in the living room (10), the occupant can move from bedroom 2 (14) to the living room (10), and in the spaces existing during the movement, the occupant can stay for less than 1 hour without adjusting the ventilation amount, and if the occupant reaches the living room (10) and sits on the sofa and stays for longer than 1 hour, the control unit can control the ventilation amount of the space in the living room (10) to increase.

[0063] Meanwhile, although not shown separately, in indoor living spaces, a specific partitioned space may be set based on a floor plan, and information transmitted from a motion sensor (451 to 481) to a control unit (600) to determine the movement of occupants and other dynamics may be calculated based on the partitioned space.

[0064] In the present invention, rather than simply controlling ventilation volume based on the movement or presence of occupants, ventilation volume is controlled by setting a first time range during which occupants remain at a specific first location, thereby enabling optimal air quality control based on the occupants' behavior (whether they are simply moving or staying at a specific location to engage in indoor activities, etc.). Furthermore, by controlling ventilation volume based on the occupants' behavior in this way, unnecessary power waste can be reduced.

[0065] Meanwhile, FIG. 5 is a schematic diagram illustrating the application of configurations of an intelligent ventilation control system according to another embodiment of the present invention. Furthermore, FIG. 6 illustrates, for convenience of explanation, an exemplary diagram illustrating the number of occupants per unit area.

[0066] Referring to FIGS. 5 and 6, in an intelligent ventilation control system according to another embodiment of the present invention, the control unit (600) may be characterized in that, when the number of occupants detected by the motion sensor (451 to 481) exceeds a first value range, the ventilation amount at the location of the occupants is further increased, and when the number of occupants exceeds a second value range, which is a value for a specific number of people per square meter set in advance, the ventilation amount at the location is further increased.

[0067] That is, when the number of occupants is small, the ventilation volume control operation is not performed, and when the number of occupants is greater than a certain first value, the ventilation volume can be increased. For example, when the first value is 3 or more, the ventilation volume is not controlled for up to 2 people, and when 3 people are identified, the ventilation volume can be controlled.

[0068] In addition, if the second value for the specific number of people per square meter (㎡) set in a preset area exceeds the range, the ventilation volume at that location can be controlled to increase. This is to create a more comfortable air quality environment by controlling the ventilation volume more precisely depending on the location of multiple occupants. If the number of occupants per square meter in a preset area is less than 3, ventilation volume control is not performed, and if it is 3 or more, ventilation volume control is performed at that location, then in the case on the left in Fig. 6, ventilation volume control is not performed, and in the case on the right, ventilation volume control is performed. This is because ventilation volume control may not be particularly necessary when the number of people does not exceed a specific number, and unnecessary ventilation volume control can be reduced, thereby reducing power consumption. In the present invention, by setting the second value for the specific number of people per square meter set in a preset location and controlling the ventilation volume at that location to increase when a large number of people are located in a specific narrow space, ventilation and air quality optimization can be automatically performed in locations and situations where it is absolutely necessary.

[0069] For example, as shown in Fig. 5, when a family stays in the living room (10), the control unit can determine that a large number of people are located per square meter and control the ventilation volume of the living room (10) to increase further. Conversely, when the same number of family members are scattered throughout bedroom 1 (13), bedroom 2 (14), and the master bedroom (11), the control unit can control the ventilation volume not to be controlled separately in a specific location. This can optimize power usage and reduce power waste.

[0070] Meanwhile, FIG. 7 is a drawing schematically showing the application of configurations of an intelligent ventilation control system according to another embodiment of the present invention.

[0071] Referring to FIG. 7, in an intelligent ventilation control system according to another embodiment of the present invention, the control unit (600) may be characterized in that when a preset bedtime is reached and no movement of the occupant is detected by the motion sensor (451 to 481) at a specific location in the indoor living space for a preset second time period, the operation of the exhaust unit (200, 300) is stopped. In the case of the first exhaust unit (200) of the bathroom (15) or the second exhaust unit (300) of the kitchen (12), the blower fan is generally operated at a location closer to the room for greater ventilation control compared to diffusers (401, 402, 403, 404, 405, 406, 411, 412, 421, 431) that control ventilation in other locations, and relatively more noise is generated. If the preset bedtime is reached and the motion sensor (451 to 481) detects no movement of the occupant at a specific location in the indoor living space for a preset second time period, the occupant is recognized as sleeping, and the exhaust unit (200, 300) that generates a lot of noise is stopped from operating when controlling the indoor air quality, so that the indoor air quality can be controlled in a more comfortable manner and optimized for the user's behavior (sleeping).

[0072] For example, as shown in Fig. 7, when the preset bedtime is reached and the occupants in the living room (11) and bedroom 1 (13) are asleep and no movement is detected, the operation of the exhaust unit (200, 300) can be stopped to prevent noise from disturbing the occupants' sleep when controlling the indoor air quality.

[0073] Meanwhile, referring back to FIGS. 1 to 4, the control unit (600) is characterized in that it determines the time of return of the occupant after going out through repeated learning, determines the time of return for the occupant by 24 hours, week, or month, and ventilates the indoor living space in advance 3 hours before the predetermined time based on the determined time of return, and if the occupant does not enter the room at the time of return, it inquires about the expected time of return of the user to the indoor living space through the user mobile phone, and performs re-ventilation based on the expected time of return entered by the user through the user mobile phone.

[0074] That is, the control unit (600) can determine the expected entry time of the occupant returning from going out through repeated learning, and ventilate the indoor living space in advance a specific three hours before the determined expected entry time, so that the occupant can have a more comfortable environment when entering the room. In addition, if the occupant does not enter the room at the expected entry time, the control unit (600) can inquire about the expected entry time from the user's mobile phone and allow the user to input the expected entry time through the user's mobile phone (not shown). The expected entry time entered through the user's mobile phone (not shown) is transmitted to the control unit (600), and the control unit can perform re-ventilation based on the expected entry time entered by the user, so that even if the occupant's entry time changes, the user can enter the room in a comfortable environment.

[0075] Meanwhile, the indoor living space may further include a window sensor unit (550) that checks whether a window leading to the outside is open or closed, and the control unit (600) may be characterized in that, when the window sensor unit (550) detects that the window is open, the amount of ventilation is controlled to increase as the distance from the window increases.

[0076] For example, when a window in which a window sensor unit (550) is arranged as shown in FIG. 1 is opened, the window sensor unit (550) confirms that the window is open, and the control unit (600) can control the ventilation amount of the diffusers (403, 404) located further away from the window to be greater than the ventilation amount of the diffusers (401, 402) adjacent to the window by a command, and can control the ventilation amount of the diffusers (405, 406) located further away to be the greatest, so that air brought in from the outside can evenly reach distant spaces indoors, and so that indoor air and outdoor air can be smoothly mixed to achieve forced ventilation.

[0077] Meanwhile, the indoor living space further includes a plurality of doors that open and close for each of a plurality of rooms in the room, and a door sensor unit (510, 520, 530, 540) that checks whether the doors are opened and closed, and the control unit (600) can increase the air intake amount of the first diffuser (411, 412) arranged in a specific first room (11) according to a command input by an occupant, thereby setting the first room (11) to a negative pressure, which is a relatively low pressure compared to other spaces, or can increase the air supply amount of the first diffuser (411, 412), thereby setting the first room (11) to a positive pressure, which is a relatively high pressure compared to other spaces. For example, if the first room is a bedroom (11), the air intake of the diffusers (411, 412) in the bedroom can be increased to configure the entire bedroom (11) with negative pressure, while the sum of the air pressures in the rest of the room can be maintained at positive pressure, so that the entire indoor space can be maintained at positive pressure, while only the bedroom (11) can be maintained at negative pressure. In addition, the air supply of the diffusers (411, 412) in the bedroom can be increased to configure the entire bedroom (11) with positive pressure, while the sum of the air pressures in the rest of the room can be maintained at positive pressure, so that the entire indoor space can be maintained at positive pressure, while only the bedroom (11) can be maintained at positive pressure.

[0078] When setting a specific space to negative pressure, for example, but not limited to, a separate filter may be formed in the pipe moving from the diffuser (411, 412) of the living room (11) to the air exchange device (100), and the air exchange device (100) may have a pipe line formed for each diffuser so that the air is purified and discharged separately from other diffusers. Accordingly, only a specific space in an indoor space can be set to negative pressure, and if a specific person among the occupants contracts an infectious disease, only the specific occupant can be isolated.

[0079] In addition, it may be characterized in that, when the first door sensor unit (510) of the first door arranged in the first room (11) is open for a specific preset 4 hours or longer, information about the fact that the first door is opened is transmitted to the user terminal. For example, when the door opening detected by the first door sensor unit (510) of the first door arranged in the bedroom (11) exceeds a specific 4 hours (e.g., 1 minute), it is determined that an occupant using a space in a negative or positive pressure state has forgotten to close the door, and an alarm may be generated or transmitted to the user terminal to induce the user to close the first door. Accordingly, the first room (11) in which a negative or positive pressure state is set can smoothly maintain the negative pressure.

[0080] Meanwhile, the control unit (600) receives power usage information located within the indoor residential space, and based on the power usage information, controls to further increase the ventilation volume of a location with high power usage. However, when power usage in the kitchen (12) is detected, the air exhaust volume of the second exhaust unit (300) is increased at a higher rate than the degree of increasing the ventilation volume of other locations. As described in various embodiments above, when an occupant is located at a specific location, the ventilation volume of the location can be increased. When power usage in the kitchen (12) is detected, it is recognized that food is being prepared in the kitchen (12), and the air exhaust volume of the second exhaust unit (300) is operated at a higher rate than the degree of increasing the ventilation volume of other locations, thereby allowing rapid ventilation.

[0081] In the case of the kitchen, compared to other spaces where occupants stay, occupants are more likely to engage in specific actions such as cooking, and this can be especially presumed to be cooking actions if lights are turned on or electrical appliances such as induction cooktops or rice cookers are used in the kitchen. In this case, more ventilation is required compared to other spaces where occupants stay, and ventilation can be achieved very effectively by increasing the air exhaust rate at a higher rate than the amount of ventilation in other spaces. In other words, in the kitchen, compared to other spaces where occupants stay still, occupants are more likely to engage in specific “actions” that generate odors (such as cooking), and especially if electricity use is detected, this can be strongly presumed to be cooking actions. Therefore, ventilation in the kitchen can be controlled to ensure smooth operation.

[0082] The control of air quality by automatically controlling the indoor ventilation volume through the control unit of the present invention described above can be controlled manually through the control wall pad (700) or the control unit (600) (or by sending a command to the control unit through the user's mobile phone).

[0083] Meanwhile, the user terminal (not shown) and the control unit (600) may include program modules that are implemented in various forms of languages ​​such as C, C++, Java, Visual Basic, Visual C, etc. and perform various functions.

For example, the recording medium may include magnetic media such as hard disks, floppy disks, and magnetic tapes, optical media such as CD-ROMs (Compact Disk Read Only Memory) and DVDs (Digital Video Disk), magneto-optical media such as floptical disks, and hardware devices specially configured to store and perform program commands such as ROMs, RAMs, and flash memories. Examples of program instructions may include not only machine language code, such as that generated by a compiler, but also high-level language code that can be executed by a computer using an interpreter or the like. Such hardware devices may be configured to operate as one or more software programs to perform the operations of the present invention, and vice versa.

[0085] In addition, a processor and memory may be provided to control the overall operation of each of the above components, and may perform operations for at least one application or program for executing a system according to an embodiment of the present invention. The processor may be configured to include a CPU (Central Processing Unit), an MPU (Micro Processor Unit), an MCU (Micro Controller Unit), or any other type of processor known in the art. In addition, the memory may be located inside or outside the processor, and may be connected to the processor by various well-known means. The memory may include a ROM (Read-Only Memory), a RAM (Random Access Memory), a flash memory, a memory card, a storage medium, and / or other storage devices.

[0086] Meanwhile, the user terminal (not shown), control unit (600), control wall pad (700), and other sensors or components may transmit and receive information through a communication network (not shown) or may be electrically connected separately. The communication network may be an infrastructure that provides wired and / or wireless communication for transmitting and receiving information between these components. In addition, the operation of the user terminal (not shown), control unit (600), and other components may enable transmission and reception between different components as needed.
