Thus, the space control system according to the present embodiment provides a free and creative new living environment that is completely different from the conventional statically fixed living environment.

  FIG. 1 schematically shows an overview of the spatial control system. The space control system 10 is acquired from a suspension device 20 provided so as to sandwich the ceiling 90, various job units 50 that can be suspended from the suspension device 20, a sensor 40 that detects various information, and the sensor 40. The control device 100 that controls the suspension device 20 according to various information and the like, and the terminal device 300 that can transmit an instruction from the user to the control device 100 are provided. The suspending device 20 does not move on a straight line or a curved line defined by a moving mechanism such as a rail, but can freely move in an arbitrary direction along the ceiling 90. As will be described later, the suspension device 20 includes an upper worker provided on the upper side of the ceiling 90 and a lower worker provided on the lower side of the ceiling. The upper worker and the lower worker are configured to attract each other through the ceiling by an attractive force such as magnetic force, so that the lower worker is fixed so as not to fall from the ceiling surface, and is integrated with the upper worker. It is movable. A suspension mechanism is provided on the lower surface of the lower worker, and the job unit 50 for providing various functions can be suspended.

[Job Unit]
The job unit 50 is suspended by the suspension device 20 and provides various functions. For example, the partition 60, the curtain 62, and the like provide a function of partitioning a space. Other examples of the job unit 50 that provides such a function include a vertical louver, a horizontal louver, a panel curtain, a vertical blind, a horizontal blind, and a door. These job units 50 may be made of a material that blocks light, or may be made of a material that transmits a certain amount of light, depending on the application. Further, these job units 50 may be made of cloth, woven fabric, or the like in order to partition the space with a free curved surface. By making these job units 50 movable, it is possible to freely change the section of the space according to the position or situation where a person is present.

  Home appliances such as the lighting 70 and the blower 72 may be provided as the job unit 50. Other examples of the job unit 50 that provides such a function include an air conditioner, a fan, an air cleaner, a humidifier / dehumidifier, an AV audio device, a television receiver, and a heavy electrical device. As will be described later, electric power may be supplied to these electric devices from the suspension device 20. In addition, an accessory store 80 for placing an accessory, a delivery device 82 for transporting an item from a storage furniture or the like to a user's position, and the like may be provided as the job unit 50. By making these job units 50 movable, it is possible to arrange necessary objects at necessary positions in accordance with the position or situation where a person is present.

  A bar-shaped baton for manually moving the suspending device 20 may be provided as the job unit 50. The user can manually move the suspension device 20 while the baton is suspended from the suspension device 20. When the movement is finished, the baton can be removed from the suspension device 20 and stored.

[Sensor]
The sensor 40 detects various information in the room. For example, the sensor 40 is a camera, an infrared camera, a microphone, an ultrasonic sensor, a temperature sensor, a person for detecting whether or not there is a person in the room and, if there is a person in the room, the position and state of the person. It may be a sensation sensor or the like. Accordingly, the position of the job unit 50 such as the partition 60 and the curtain 62 can be changed according to whether or not there is a person in the room, and the compartment in the room can be changed. Further, depending on the position of the person in the room, the lighting 70, the blower 72, the accessory stand 80, etc. are arranged around the person, or when a plurality of persons are in the room, the partition 60 or the like A curtain 62 or the like can be arranged.

[Ceiling structure]
In order to allow the suspension device 20 to move freely along the ceiling 90, the upper surface and the lower surface of the ceiling 90 are at least partially constituted by smooth planes or curved surfaces. The presence of unevenness that allows the upper worker and the lower worker to get over and move is allowed. Even if there are irregularities that the upper worker and the lower worker cannot get over, if such irregularities can be moved, the existence of such irregularities is allowed. Since the upper worker and the lower worker move integrally, in order for the suspension device 20 to move, both the upper surface and the lower surface of the ceiling need to be flat enough to allow the upper worker and the lower worker to move. is there. A region surrounded by a barrier that one of the upper worker and the lower worker cannot get over is a region in which the suspension device 20 can move.

  In general dwellings and buildings, the lower surface of the ceiling of a room is often composed of a flat surface, but joists, electrical wiring, hot and cold water ducts, exhaust ducts, piping, etc. are arranged on the upper surface, that is, the back surface. In this case, the range in which the upper worker can freely move is limited. In the space control system 10 according to the present embodiment, in order that the upper worker can freely move over a wide range of the ceiling, building materials such as joists are not arranged on the top surface of the ceiling as much as possible. However, it should not be placed near the center of the ceiling, but near the outer periphery or corner. A ceiling is good also as a structure which suspends a ceiling surface material from the member in the upper part. In addition, the electrical wiring, hot / cold water duct, exhaust duct, piping, and the like may be provided so as to be suspended from a member above and suspended from the ceiling 90 instead of being placed directly on the upper surface of the ceiling 90. When the space control system 10 of the present embodiment is introduced into an existing residence or building, a new ceiling for installing and moving the suspension device 20 may be provided below the existing ceiling. .

  The thickness of the ceiling surface should be thinner than the maximum value, which is the thickness at which the lower worker and the job unit 50 suspended by the lower worker do not fall, so that the attractive force works between the lower worker and the upper worker. is there. Conversely, a magnet or the like may be selected so that the attractive force acting between the lower worker and the upper worker is sufficiently strong with respect to the thickness of the ceiling surface. Note that the thickness of the ceiling surface does not have to be constant in the entire region in which the suspension device 20 can move, and may vary within a range not exceeding the above maximum value.

  The ceiling surface material needs to be strong enough to support the weight of the suspension device 20 and the job unit 50. In order to prevent the ceiling surface material from being greatly bent even when the suspending device 20 is concentrated near the center of the ceiling, it is desirable that the ceiling surface material is made of a material having an appropriate rigidity. The ceiling surface material may be, for example, a composite panel of metal and resin (upper and lower metal plates such as aluminum and stainless steel, and a core material is a resin plate), a metal honeycomb panel (a metal honeycomb structure such as aluminum and stainless steel), and the like. .

[Power supply mechanism]
Since the upper worker of the suspension device 20 needs electric power for movement, a mechanism for supplying power to the upper worker is necessary. In addition, when the lower worker or the job unit 50 suspended by the lower worker needs electric power for movement or various functions, the lower worker or the job unit 50 needs to be supplied with power. As an example of such a power supply mechanism, on the upper side of the ceiling 90, the upper worker is always supplied with power by a wiring or non-wiring technique, and the lower worker is supplied from the supplied upper worker by a non-contact power supply technique, and jobs such as lighting and home appliances The unit 50 may be powered. A part or all of the upper surface of the ceiling 90 may be configured by a conductive member, and power may be supplied to the upper worker via the conductive member. When only a part of the upper surface of the ceiling 90 is configured by the conductive member, the position of the upper worker after the movement may be limited to the conductive member.

  A battery for charging the required amount of power may be provided in the upper worker or the lower worker, and power may be supplied to the job unit 50 from the battery. In this case, a charging pit for charging the battery may be provided on the ceiling 90, and power may be supplied from the charging pit to the battery. The upper worker's battery may be charged in the charging pit, and the lower worker and the job unit 50 may be supplied with power from the upper worker by a non-contact power feeding technique. Both the lower worker's batteries may be rechargeable. The upper worker or the lower worker carrying the battery may move to the charging pit autonomously or charge the battery when the amount of charge of the battery falls below a predetermined value, or by an instruction from the control device 100. Good.

[Hanging device]
FIG. 2 schematically shows the external appearance of the suspension device according to the embodiment. The suspension device 20 includes an upper worker 200 provided on the upper side of the ceiling 90 and a lower worker 30 provided on the lower side of the ceiling 90. The upper worker 200 includes a permanent magnet 22, a moving mechanism 24, and a coil 26. The lower worker 30 includes a permanent magnet 32, a moving mechanism 34, a coil 36, a suspension mechanism 38, and a charging lamp 39.

  The permanent magnet 22 and the permanent magnet 32 are each magnetized to be weaker than the saturation magnetization, and are arranged in such a direction that they attract each other. The moving mechanism 24 and the moving mechanism 34 are mechanisms for the upper worker 200 and the lower worker 30 to move in any direction along the ceiling 90, and may be wheels, a rotating ball, or the like, for example. The permanent magnet 22 is provided at a position higher than the ground plane of the moving mechanism 24 so as not to contact the ceiling 90. The same applies to the permanent magnet 32. The suspension mechanism 38 is a mechanism for detachably suspending the job unit 50, and may be a magnet, a hook, a screw, or the like. Alternatively, a mechanism for hanging may be used. In the example of this figure, the suspension mechanism 38 is a magnet, and the job unit 50 is suspended by a magnetic force between the suspension unit 38 and a magnet provided on the upper part of the job unit 50.

  The coil 26 is wound around the permanent magnet 22 so that the center position thereof matches the center position of the permanent magnet 22. The coil 36 is wound around the permanent magnet 32 so that the center position thereof coincides with the center position of the permanent magnet 32. The coil 26 and the coil 36 function as an electromagnet, and also function as a power receiving coil when charging the battery.

  When the lower worker 30 is removed from the ceiling 90, a magnetic field is generated in a direction that cancels the magnetic force acting between the permanent magnet 22 and the permanent magnet 32, that is, a direction opposite to the magnetic field between the permanent magnet 22 and the permanent magnet 32. Then, one or both of the coil 26 and the coil 36 are energized. Thereby, the lower worker 30 fixed to the ceiling 90 by the attractive force between the permanent magnet 22 and the permanent magnet 32 can be easily removed.

  When the upper worker 200 and the lower worker 30 are moved, one or both of the coil 26 and the coil 36 are generated so as to generate a magnetic field in a direction that cancels the magnetic force acting between the permanent magnet 22 and the permanent magnet 32, that is, a reverse direction. Energize to. At this time, a weaker current is applied than when the lower worker 30 is removed. Thereby, the attractive force between the permanent magnet 22 and the permanent magnet 32 pressing the moving mechanism 24 and the moving mechanism 34 against the ceiling 90 is weakened, and the frictional force between the moving mechanism 24 and the lower surface of the ceiling 90 and the moving mechanism 34 are reduced. Since the friction force between the upper surface of the ceiling 90 can be weakened, the upper worker 200 and the lower worker 30 can be moved smoothly.

  When the lower worker 30 and the job unit 50 cannot be fixed to the ceiling 90 only by the magnetic force between the permanent magnet 22 and the permanent magnet 32, such as when the job unit 50 heavier than the predetermined value is suspended by the lower worker 30 The coil 26 and the coil 36 are energized so that a magnetic force acting between the permanent magnet 22 and the permanent magnet 32 is generated, that is, a magnetic field in the same direction is generated. Thereby, the lower worker 30 can be fixed to the ceiling 90 more reliably.

  In the example of this figure, a power transmission coil 92 as a charging pit is provided inside the ceiling surface material. When the charge amount of the battery of the upper worker 200 or the lower worker 30 falls below a predetermined value, the suspension device 20 moves to the position where the power transmission coil 92 is provided, and the center position of the coil 26 and the coil 36 and the power transmission coil 92 Align so that it matches the center position. When a current flows through the power transmission coil 92, a current flows through the coil 26 and the coil 36 due to the generated magnetic field, and the battery is charged. The direction of the current flowing through the power transmission coil 92, the winding direction of the coil 26 and the coil 36, and the polarity of the battery so that the batteries of both the upper worker 200 and the lower worker 30 are charged when the power transmission coil 92 is energized. May be set.

  Electric power may be supplied from the upper worker 200 to the lower worker 30. In this case, the coil 26 functions as a power transmission coil, and the coil 36 functions as a power reception coil. The lower worker 30 may charge the battery with the received power. Alternatively, the battery may not be mounted and power may be supplied from the upper worker 200 whenever power is used. The winding direction of the coil 26 and the coil 36 so that a magnetic field in a direction in which the upper worker 200 and the lower worker 30 attract each other is generated when a current is passed through the coil 26 to supply power to the lower worker 30 from the upper worker 200. , And the direction of the current flowing through the coil 26 may be set.

  The charge lamp 39 notifies the charge amount of the battery of the upper worker 200 or the lower worker 30. For example, when the charge amount is greater than or equal to a predetermined value, light is emitted in green, and when the charge amount is less than the predetermined value, light is emitted in red.

  The worker management unit 118 manages the suspension device 20 based on information stored in the storage device 150 and instructions from the user. The worker management unit 118 determines a position where the suspension device 20 should be moved in accordance with the indoor situation or an instruction from the user. The worker management unit 118 refers to the map held in the environment information holding unit 154 and confirms whether or not the determined position is within an area where the suspension device 20 can move, and the movable area If it is within, a movement instruction is transmitted to the suspension device 20. If it is not within the movable area, the position to be moved so as to be within the movable area is determined again. Alternatively, the terminal device 300 is notified that the area is not movable.

  The worker management unit 118 may determine a movement route from the current position of the suspension device 20 to a position to be moved with reference to a map or the like held in the environment information holding unit 154.

[Upper worker]
FIG. 4 shows functional blocks of the upper worker according to the embodiment. The upper worker 200 includes a communication unit 202, a control unit 210, and a storage device 250. The communication unit 202 controls communication among the control device 100, the lower worker 30, and the terminal device 300. The communication unit 202 may communicate with the control device 100, the lower worker 30, and the terminal device 300 using any wired or wireless communication technology.

  The storage device 250 includes a worker information holding unit 252. The worker information holding unit 252 holds information about the own device and information about the job unit 50 suspended by the lower worker 30 that moves integrally with the own device. The worker information holding unit 252 includes the type of the job unit 50 suspended from the lower worker 30, the current position of the upper worker 200, the elapsed time since the upper worker 200 was moved to the current position, the amount of charge of the battery, and the like. Keep information. These pieces of information may be acquired from the lower worker 30, may be acquired from the control device 100, or may be acquired from the terminal device 300.

  The control unit 210 includes an instruction receiving unit 212, a job unit information acquisition unit 214, a user instruction acquisition unit 216, and a worker control unit 218.

  The instruction receiving unit 212 receives an instruction transmitted from the control device 100. The job unit information acquisition unit 214 acquires information about the job unit 50 suspended from the lower worker 30 from the lower worker 30, the control device 100, or the terminal device 300 and records it in the storage device 250. The user instruction acquisition unit 216 acquires a user instruction from the terminal device 300.

  The worker control unit 218 controls the upper worker 200, the lower worker 30, and the job unit 50 based on an instruction from the control device 100 or an instruction from the user. When the worker control unit 218 acquires a position to be moved or a movement route to the position to be moved from the control device 100 or the terminal device 300, the worker control unit 218 controls the moving mechanism 24 to move the upper worker 200. The worker control unit 218 may control the speed or acceleration of movement by the moving mechanism 24 according to the type of the job unit 50 suspended from the lower worker 30. For example, when a job unit 50 that is heavy and easily shakes, or a job unit 50 that should not be shaken, such as home appliances, is suspended, a job unit that can be shaken such as a curtain while suppressing the speed and acceleration to be small. If 50 is suspended, the speed and acceleration may be increased.

  The worker control unit 218 may calculate the moving distance and moving direction of the own device from the rotation amount of the rotating ball that is the moving mechanism 24, and may further calculate the current position. The upper worker 200 may be provided with an acceleration sensor or a GPS receiver, and the current position of the own device may be calculated from the information. The worker control unit 218 calculates the movement direction from the current position and the position to be moved at a predetermined timing during movement, and controls the movement mechanism 24.

  When the upper worker 200 or the lower worker is provided with a proximity sensor and the suspension device 20 is moved, it approaches an obstacle such as a building material disposed on the upper surface or the lower surface of the ceiling 90 or another suspension device 20. When it is detected, the worker control unit 218 may change the moving direction of the upper worker 200 and move the upper worker 200 so as to avoid the detected object.

  As described above, when the worker control unit 218 obtains an instruction to remove the lower worker 30 from the terminal device 300, a magnetic field opposite to the magnetic field between the permanent magnet 22 and the permanent magnet 32 is generated. The lower worker 30 is instructed to energize the coil 26 and energize the coil 36. When the worker control unit 218 moves the upper worker 200 and the lower worker 30, the worker control unit 218 energizes the coil 26 so that a magnetic field opposite to the magnetic field between the permanent magnet 22 and the permanent magnet 32 is generated. The lower worker 30 is instructed to be energized. In this case, since it is not necessary to generate a magnetic field in the reverse direction so strong that the lower worker 30 falls from the ceiling 90, the magnitude of the current to be energized may be smaller than when the lower worker 30 is removed. When the worker control unit 218 is notified from the lower worker 30 or the terminal device 300 that the job unit 50 heavier than the predetermined value is suspended from the lower worker 30, the worker control unit 218 determines between the permanent magnet 22 and the permanent magnet 32. The lower worker 30 is instructed to energize the coil 26 and energize the coil 36 so that a magnetic field having the same direction as the magnetic field is generated.
