Description

The present invention relates to an air conditioning system including an unmanned aerial vehicle provided with temperature measuring means.

The role of the air-conditioning system is to uniformly create a comfortable temperature/humidity space in an air-conditioned space such as a room, or to create a comfortable temperature/humidity space according to the position of the human body in the air-conditioned space. Here, the comfortable temperature/humidity space is a space in which the comfort based on the temperature and humidity of the air is equal to or higher than the setting reference.

For example, when the shape of the room is not rectangular, or when the room has a heat source, temperature unevenness often occurs depending on the location, and thus the temperature and humidity are often not uniform. BACKGROUND ART Conventionally, various sensors are mounted on an indoor unit that constitutes an air conditioning system in order to measure temperature and humidity of air. For example, an indoor unit in which an infrared sensor is mounted on a main body is known (for example, see Patent Document 1), and such an outdoor unit detects a temperature in a range directly visible by the infrared sensor.

The remote controller 80 and the indoor unit 10 may be connected wirelessly or by wire.

FIG. 3 is a block diagram illustrating the functional configuration of the unmanned aerial vehicle and the indoor unit of FIG. As shown in FIG. 3, the unmanned aerial vehicle 30 includes a power supply receiving unit 31, a sensor unit 32, a flying body control unit 33, a flying body communication unit 34, a motor 35, a propeller 36, and an operating unit 37. ,have. The control unit 40 includes a power supply unit 41, an air conditioner control unit 43, and an air conditioner communication unit 44. In addition, the indoor unit 10 includes, for example, a thermistor, and has an air temperature sensor 42 that measures the temperature of the air in the air-conditioned space S. In the first embodiment, the air temperature sensor 42 is provided in the vicinity of the suction port 11 and detects the temperature of the air sucked through the suction port 11.

The power supply receiving unit 31 receives power from the power supply unit 41, and has a power receiving coil 31a and a rechargeable battery 31b. The power supply receiving unit 31 is configured to store the power received by the power receiving coil 31a in the rechargeable battery 31b. The motor 35 is driven by the flight body control unit 33. The propeller 36 rotates using the motor 35 as a power source.

The sensor unit 32 has position detecting means 32a for detecting information indicating the position in the air-conditioned space S as position information, and temperature detecting means 32b for detecting the temperature of air as temperature information. In the first embodiment, the position detecting means 32a includes an infrared sensor 38 and a gyro sensor 39. That is, the position detecting means 32a detects, as position information, information on the distance from the wall or the like detected by the infrared sensor 38 and information on the change in the orientation of the unmanned aerial vehicle 30 detected by the gyro sensor 39. The position detection unit 32a transmits the detected position information to the air conditioner control unit 43 via the flight body communication unit 34.

The temperature detecting means 32b includes a thermistor and detects the temperature in the vicinity of the unmanned aerial vehicle 30 as temperature information. The temperature detecting means 32b transmits the detected temperature information to the air conditioner control unit 43 via the flight body communication unit 34. The temperature information may be detected at intervals of about 50 [cm] to 200 [cm] in both the horizontal and vertical directions. When detecting temperature information with the thermistor mounted on the drone, the wind blows downward from the drone in flight, so the upper part of the drone has less turbulence in the air flow, so the upper part from the bottom It is preferable to detect the temperature information toward the head.

Here, the infrared sensor 38 may function as "temperature detecting means" that detects the temperature of the air as temperature information and transmits the detected temperature information to the air conditioner controller 43. In this case, the thermistor as the temperature detecting means 32b may be omitted, or the infrared sensor 38 and the thermistor as the temperature detecting means 32b may be used together. That is, the temperature information is transmitted from both the infrared sensor 38 and the temperature detecting means 32b to the air conditioner controller 43, and the air conditioner controller 43 is transmitted from each of the infrared sensor 38 and the temperature detecting means 32b. The temperature information obtained may be used for air conditioning control. When the temperature information is detected by the infrared sensor 38, the unmanned aerial vehicle 30 can be kept at a position higher than the human body H, so that contact or collision between the human body H and the unmanned aerial vehicle 30 can be avoided. The safety can be improved.

The operation unit 37 receives an operation or the like for instructing adjustment of the temperature environment around the unmanned aerial vehicle 30. FIG. 3 shows an example in which the operation unit 37 has a decrease button 37a for instructing a decrease in the ambient temperature and an increase button 37b for instructing an increase in the ambient temperature. When the user presses the lowering button 37a, the operation unit 37 transmits a lowering request signal requesting the lowering of the temperature to the air conditioner control unit 43. When the user presses the rise button 37b, the operation unit 37 transmits an increase request signal requesting an increase in temperature to the air conditioner control unit 43.

In the example of FIG. 3, the letters "hot" are attached to the lower button 37a and the letters "cold" are attached to the up button 37b so that the user can perform an intuitive operation, but the present invention is not limited to this. Not done. The down button 37a and the up button 37b may be given other arbitrary characters, or the down button 37a may be marked with "▽" and the up button 37b may be marked with "△". May be attached.

Further, the unmanned aerial vehicle 30 has a function of detecting and avoiding obstacles and the like. That is, the flying body control unit 33 detects the distance from a wall or an obstacle based on the detection data from the infrared sensor 38, and the unmanned flying body prevents the flying body 30A from hitting the wall or obstacle. Control 30 flights. Then, the aircraft control unit 33 executes the processing in the detection mode in which the position information, the temperature information, and the like are detected while the flight and the stop are performed in response to the operation command from the air conditioner control unit 43. The detection modes of the aircraft control unit 33 include an installation mode, a patrol mode, a personal mode, and a combined mode.

In any detection mode, the flying body control unit 33 leaves enough power to return to the power feeding base unit 15 and causes the unmanned aerial vehicle 30 to return to the power feeding base unit 15 before the power is used up. .. That is, the flying body control unit 33 has a function of returning the unmanned flying vehicle 30 to the power feeding base unit 15 when the remaining power falls below the threshold value. This threshold is set according to the characteristics of the unmanned aerial vehicle 30 and the like, and can be changed as appropriate.

However, the flying body control unit 33 may manage the timing of returning the unmanned flying body 30 by the elapsed time or the flight time. For example, the flying vehicle control unit 33 may cause the unmanned aerial vehicle 30 to return to the power feeding base unit 15 when the elapsed time after leaving the power feeding base unit 15 reaches the elapsed upper limit time. Further, the flying body control unit 33 may cause the unmanned aerial vehicle 30 to return to the power feeding base unit 15 when the flight time after leaving the power feeding base unit 15 reaches the flight upper limit time. Further, the flying body control unit 33 has a weighting coefficient corresponding to at least one of the flight time and the stop time in the internal memory or the like, and the conversion time obtained by converting the flight time and the stop time by the weighting coefficient becomes the conversion upper limit time. When reaching, the unmanned aerial vehicle 30 may return to the power feeding base portion 15. The elapsed upper limit time, the flight upper limit time, and the conversion upper limit time are set based on the characteristics of the unmanned aerial vehicle 30 and can be changed as appropriate.

The installation mode is a mode of initial operation performed when the air conditioning system 100 is installed. That is, the flight control unit 33 drives the motor 35 in order to grasp the shape and size of the air-conditioned space S at the time of first activation, and causes the unmanned flight vehicle 30 to fly on a flight route based on the set conditions. .. As a result, the aircraft control unit 33 collects ambient environment information including information such as the shape and size of the air-conditioned space S and the configuration of obstacles, and stores it in an internal memory or the like.

The patrol mode, the personal mode, and the combined mode are detection modes executed after the installation mode. In the patrol mode, the unmanned aerial vehicle 30 is caused to periodically fly toward a corner of a room or the vicinity of a human body, and the temperature of each place and the temperature of the human body are detected and transmitted to the air conditioner controller 43. The flying body control unit 33 may obtain the temperature information from the temperature detection unit 32b as the temperature of each place, or may obtain the temperature information from the infrared sensor 38. In addition, the flying body control unit 33 acquires the detection data detected by the infrared sensor 38 as the temperature of the human body.

The drone as the unmanned aerial vehicle 30 has a predetermined flight time with one charge. Therefore, in the patrol mode, the aircraft control unit 33 repeatedly executes the patrol process in which the unmanned aerial vehicle 30 is caused to fly for a set time and then returns to the power feeding base unit 15 to be charged. The flying body control unit 33 acquires data detected by the position detecting unit 32a and the temperature detecting unit 32b over time while the unmanned flying vehicle 30 is flying. In the first embodiment, the aircraft control unit 33 sequentially transmits the position information and the temperature information acquired during the flight to the air conditioner control unit 43. The set time is preset according to the characteristics of the unmanned aerial vehicle 30 and the size of the air-conditioned space S, and can be changed as appropriate. Note that the time for keeping the unmanned aerial vehicle 30 on the power feeding base portion 15 may be longer than the time until the charging is completed.

The personal mode is a mode in which the temperature detecting means 32b or the infrared sensor 38 is used as a temperature sensor for personal air conditioning. The unmanned aerial vehicle 30 of the first embodiment can acquire the position information and the temperature information by the position detecting means 32a and the temperature detecting means 32b even when the unmanned aerial vehicle 30 is stopped. In the personal mode, the aircraft control unit 33 lands the unmanned aerial vehicle 30 near a specific user, that is, on the desk used by the specific user or on the bedside of the bedroom, and the temperature information around the user. Is transmitted to the air conditioner control unit 43 every management time. The management time is set to 5 minutes, for example, and can be changed as appropriate.

Thus, even when the unmanned aerial vehicle 30 is at rest, that is, when it is landing in a space near the user or the like, the position detecting means 32a and the temperature detecting means 32b periodically detect the position information and the temperature information. It has the function of detecting. Then, the unmanned aerial vehicle 30 of the first embodiment sequentially transmits the position information and the temperature information detected when the vehicle is stopped to the air conditioner control unit 43.

For example, when it is desired to adjust only the air environment around a specific user, it is not necessary to fly the unmanned aerial vehicle 30 over the entire air-conditioned space S. Therefore, in such a case, it is advisable to land the unmanned aerial vehicle 30 that has taken off the power feeding base unit 15 at a specific point from the beginning and continuously detect the air environment of the place by the personal mode.

The personal mode may be executed for a plurality of users. For example, when a plurality of users are detected from the detection data of the infrared sensor 38, the air vehicle control unit 33 causes the unmanned air vehicle 30 to move around in a position near each user for each set individual air conditioning time. You may control. By doing so, it is possible to improve the comfort of each of the plurality of users.

The composite mode is a mode in which a part of the traveling mode and the personal mode are combined. That is, in the combined mode, the flying body control unit 33 firstly flies the unmanned flying body 30 along the set flight route, and acquires the position information and the temperature information acquired by the position detecting unit 32a and the temperature detecting unit 32b over time. To the air conditioner controller 43. After that, the aircraft control unit 33 lands the unmanned aerial vehicle 30 near a specific user without returning to the home, uses the remaining power, and acquires the temperature information of the place for each management time to air-condition. It is transmitted to the machine control unit 43.

When the unmanned aerial vehicle 30 returns to the power feeding base unit 15, the flight control unit 33 transmits a return signal to the air conditioner control unit 43. Further, when the charging of the unmanned aerial vehicle 30 is completed, the flight body control unit 33 transmits a completion signal to the air conditioner control unit 43. The air vehicle communication unit 34 can perform wireless communication with the indoor unit 10 by a wireless LAN such as WiFi (registered trademark: the same applies below) or any communication standard such as Bluetooth (registered trademark: the same applies below). it can.

The power supply unit 41 includes a power supply coil 41 a for supplying power to the power supply receiving unit 31. The air conditioner communication unit 44 communicates with the outdoor unit 20 and the unmanned aerial vehicle 30. The air conditioner communication unit 44 can perform wireless communication with the unmanned aerial vehicle 30 by a wireless LAN such as WiFi or any communication standard such as Bluetooth.

The air conditioner control unit 43 controls the power supply control unit 43a that controls the power supply process by the power supply unit 41, the flight body processing unit 43b that controls the unmanned air vehicle 30, and the operation that controls the actuator such as the indoor blower of the indoor unit 10. And a control unit 43c. Here, the outdoor unit 20 has an outdoor control unit (not shown) that controls various actuators provided inside the outdoor unit 20, and the operation control unit 43c cooperates with the outdoor control unit. The control of the air conditioning system 100 is executed.

When the power feeding control unit 43a receives the homing signal from the flying body control unit 33, the power feeding control unit 43a transmits power to the power feeding coil 41a and performs power feeding to the power receiving coil 31a. Further, when the power feeding control unit 43a receives the completion signal from the flying body control unit 33, the power feeding to the power feeding coil 41a is stopped by stopping the power feeding to the power feeding coil 41a.

The operation control unit 43c acquires the position information transmitted from the position detection unit 32a and the temperature information transmitted from the temperature detection unit 32b as a pair of information. That is, the position information and the temperature information are associated with each other on a one-to-one basis. When the infrared sensor 38 is caused to function as the temperature detecting unit, the operation control unit 43c acquires the position information transmitted from the position detecting unit 32a and the temperature information transmitted from the infrared sensor 38 as a pair of information.

The operation control unit 43c uses, as operation modes, a basic mode in which air conditioning is performed using measurement data from the air temperature sensor 42 provided in the indoor unit 10, and a flight in which air conditioning is performed by utilizing detection data from the unmanned air vehicle 30. And a body mode.

Here, the remote controller 80 has a function of accepting an operation for designating and switching the operation mode. When the remote controller 80 receives the operation of designating the basic mode or instructing the switching to the basic mode, the remote controller 80 transmits a basic command signal instructing the operation in the basic mode to the operation control unit 43c. Further, when the remote controller 80 receives an operation for designating the flight object mode or for instructing switching to the flight object mode, the remote controller 80 transmits a flight object command signal instructing the operation in the flight object mode to the operation control unit 43c.

When the basic command signal is transmitted from the remote controller 80, the operation control unit 43c does not operate the unmanned aerial vehicle 30 and executes the air conditioning of the air conditioning space S in the basic mode. That is, the operation control unit 43c cooperates with the outdoor control unit based on the measurement data obtained by the air temperature sensor 42 provided in the indoor unit 10 and the pressure sensor provided in the outdoor unit 20, and the like. It controls various actuators of the outdoor unit 20.

The operation control unit 43c requests the operation of the unmanned air vehicle 30 from the air vehicle processing unit 43b when the air vehicle command signal is transmitted from the remote controller 80. The flying body processing unit 43b transmits an operation command to the flying body control unit 33 of the unmanned aerial vehicle 30 in response to a request from the movement control unit 43c. Here, the remote controller 80 may have a function of accepting a detection mode selection operation, and in this case, the flying body processing unit 43b issues an operation command including information on the selected detection mode to the flying body control unit. 33.

The operation control unit 43c controls the actuators of the indoor unit 10 and the outdoor unit 20 according to the decrease request signal from the operation unit 37. For example, during the cooling operation, the operation control unit 43c controls the angles of the upper and lower flaps and the left and right louvers of the indoor unit 10 and adjusts the wind toward the unmanned air vehicle 30. The operation control unit 43c controls the actuators of the indoor unit 10 and the outdoor unit 20 according to the rising request signal from the operation unit 37. For example, during the cooling operation, the operation control unit 43c controls the angles of the upper and lower flaps and the left and right louvers of the indoor unit 10 and adjusts so that the wind does not blow toward the unmanned air vehicle 30.

Here, the flying body control unit 33 and the air conditioner control unit 43 can be configured by a computing device such as a microcomputer and software that cooperates with such a computing device to realize the above-described functions. The aircraft control unit 33 and the air conditioner control unit 43 may include hardware such as a circuit device that realizes a part of the functions described above.

FIG. 4 is an enlarged perspective view showing the unmanned aerial vehicle of FIG. FIG. 5 is a plan view of the unmanned aerial vehicle of FIG. 2 and its surroundings as viewed from above. FIG. 6 is a schematic cross-sectional view of the unmanned aerial vehicle, the power feeding base portion, and the upper portion of the control unit extracted from the cross-section taken along the line AA of FIG. 5. With reference to Drawing 4-Drawing 6, composition of unmanned air vehicle 30 and its circumference is explained roughly.

As shown in FIGS. 4 and 5, the unmanned aerial vehicle 30 of the first embodiment has four propellers 36 and four motors 35 that drive each propeller 36 (not shown in FIGS. 4 and 5 ). Have). In addition, in the first embodiment, the sensor unit 32 is provided in the center of the inside of the flying body 30A. The power receiving coil 31a is arranged around the aircraft body 30A. The rechargeable battery 31b is connected to the power receiving coil 31a, and is provided between two adjacent propellers 36 inside the aircraft body 30A. Although not shown in FIGS. 4 and 5, the unmanned aerial vehicle 30 is provided with four rechargeable batteries 31b, and each rechargeable battery 31b is provided between two adjacent propellers 36, respectively. Has been.

As shown in FIG. 6, the power feeding coil 41a has a shape corresponding to the power receiving coil 31a arranged around the aircraft body 30A. Therefore, when the unmanned aerial vehicle 30 returns to the power feeding base portion 15, the power receiving coil 31a and the power feeding coil 41a are arranged to face each other. As a result, power can be efficiently supplied from the power feeding coil 41a to the power receiving coil 31a.

As described above, the air conditioning system 100 according to the first embodiment performs the air conditioning of the air conditioning space S using the position information and the temperature information acquired as a pair of information from the unmanned air vehicle 30. Therefore, since the three-dimensional temperature state of the air-conditioned space S can be grasped, the comfort of the air-conditioned space S can be improved. That is, since the position information and the temperature information acquired by the air conditioner control unit 43 are linked as a pair of information, it is possible to grasp the detailed temperature distribution of the air conditioning space S. Therefore, even when the air conditioning system 100 targets a room with a high ceiling, for example, it is possible to realize highly accurate air conditioning control.

That is, according to the air conditioning system 100, it is possible to detect the state in which the temperature unevenness occurs in the air-conditioned space S in association with the position of the unmanned air vehicle 30. Therefore, the temperature of the air-conditioned space S can be made uniform by blowing cool air or warm air to the portion where the temperature unevenness occurs. Further, the unmanned aerial vehicle 30 can acquire temperature information for each position during flight. Therefore, the air conditioner control unit 43 can individually adjust the air environment for each position based on the temperature information acquired from the unmanned air vehicle 30, so that more detailed air conditioning control can be realized.

Further, the unmanned aerial vehicle 30 detects the position information and the temperature information by the position detecting means 32a and the temperature detecting means 32b not only during the flight but also during the stop. Then, the air conditioner control unit 43 air-conditions the air-conditioned space S using the position information and the temperature information while the unmanned aerial vehicle 30 is stopped. Therefore, on the indoor unit 10 side, the temperature environment around a specific position can be continuously managed and can be utilized for the air conditioning of the air conditioning space S, so that the air conditioning efficiency can be improved. In particular, in the personal mode or the like, the unmanned aerial vehicle 30, which lands near the user's hand or at the bedside of the bedroom, transmits the temperature information around the user to the air conditioner control unit 43 every management time. Therefore, it is possible to realize more accurate air conditioning control than when the temperature sensor built in the indoor unit 10 or the remote controller 80 is used, and thus it is possible to further improve comfort. Although the flight time of the drone as the unmanned aerial vehicle 30 is relatively short, the electric power required for sensing is very small, so that it is possible to realize personal air conditioning for a relatively long time such as during work or sleep.

Further, the indoor unit 10 has a power supply base portion 15 for the homeless charging of the unmanned aerial vehicle 30. Therefore, it is not necessary to separately provide a charging device for the unmanned aerial vehicle 30. Here, in general, the indoor unit 10 is provided at a position higher than the user's head, but the power feeding base portion 15 of the first embodiment is formed on the upper surface of the main body portion 10A. As described above, by providing the power feeding base 15 on the upper part of the indoor unit 10 and returning the unmanned aerial vehicle 30 from the space between the ceiling and the indoor unit 10, contact between the unmanned aerial vehicle 30 and the user at the time of returning home. Etc. can be avoided.

Here, when the unmanned aerial vehicle 30 is a drone, although its control technology is improving year by year, many propellers are exposed for weight reduction, and the drone can fly within the operating range of the human body. There are risks to safety. Therefore, it is desirable to limit the flight range of the drone to a range from the ceiling to a height of about 2 [m]. In this respect, the power supply base portion 15 on which the unmanned aerial vehicle 30 takes off and land even when the flight range of the unmanned aerial vehicle 30 is limited as described above is provided in the indoor unit 10 mounted above the room. Therefore, the unmanned aerial vehicle 30 can always be arranged above the living space, including when taking off and landing on the power feeding base portion 15, so that a safer and more comfortable air-conditioned space S can be created. However, the flight range of the drone may be a range from the lower limit height set to 2 [m] or less to the ceiling according to the height of the air-conditioned space S.

By the way, in reality, the gap above the indoor unit 10 is often very narrow. Therefore, it is assumed that the unmanned aerial vehicle 30 cannot smoothly return to the power feeding base unit 15. Therefore, the front panel of the main body 10A may be provided with an openable storage part, and the power supply base part 15 may be provided in this storage part. Further, the power supply base portion 15 formed of a material to which a magnet is attached may be provided in a part of the main body portion 10A, and an electromagnet may be mounted on the unmanned aerial vehicle 30. Then, when the unmanned aerial vehicle 30 returns home, the flying vehicle control unit 33 may energize the electromagnet to fix the unmanned aerial vehicle 30 to the power feeding base unit 15. With this configuration, the power supply base portion 15 can be provided not only on the upper surface of the main body portion 10A but also on the side surface or the bottom surface. In addition, when the air conditioning system 100 has a plurality of unmanned aerial vehicles 30, the number of variations in the location where the power feeding base unit 15 is provided increases, so that each unmanned aerial vehicle 30 can be homed and charged in a timely manner.

Further, the unmanned aerial vehicle 30 of the first embodiment returns to the power feeding base unit 15 when a predetermined condition based on the threshold value or each upper limit time is satisfied. For example, the unmanned aerial vehicle 30 may return to the power feeding base unit 15 when the remaining power falls below the threshold value. Further, the unmanned aerial vehicle 30 may return to the power feeding base unit 15 when the elapsed time after leaving the power feeding base unit 15 reaches the elapsed upper limit time. Then, the unmanned aerial vehicle 30 can be charged in the power supply base portion 15 of the indoor unit 10 by a non-contact method such as Qi. Therefore, it is possible to eliminate the troublesomeness of the charging work by the user and to continuously obtain the sensing data by the regular flight of the unmanned aerial vehicle 30.

Embodiment 2.
Since the overall configuration of the air conditioning system in the present Second Embodiment is the same as that in First Embodiment, the same components as those in First Embodiment will be designated by the same reference numerals and description thereof will be omitted. The air conditioning system 100 according to the second embodiment uses the data detected by the infrared sensor 38 mounted on the unmanned aerial vehicle 30 for personal air conditioning.

In the second embodiment, as the infrared sensor 38, an infrared camera that takes a temperature distribution of the air-conditioned space S as an image and outputs the taken image to the flight control unit 33 is adopted. This infrared camera has a changeable angle and a variable imaging direction. The image captured by this infrared camera is a matrix-shaped thermal image or an array-shaped thermal image in a direction perpendicular to the traveling direction. However, the unmanned aerial vehicle 30 may be equipped with an infrared camera that captures the temperature distribution of the air-conditioned space S as an image, separately from the infrared sensor 38. Then, the air conditioner control unit 43 uses the image captured by the infrared camera for air conditioning of the air conditioned space S.

FIG. 7 is an explanatory diagram illustrating the visual field range and sensor angle of the infrared sensor provided in the unmanned aerial vehicle according to Embodiment 2 of the present invention. FIG. 8 is an explanatory diagram showing an example of a state in which a human body enters the visual field range of the infrared sensor of FIG. Position control of the unmanned aerial vehicle 30 will be described with reference to FIGS. 7 and 8. The white arrows in FIGS. 7 and 8 indicate the flight direction of the unmanned aerial vehicle 30. The same applies to the following figures.

The unmanned aerial vehicle 30 according to the second embodiment detects the temperature of a region obliquely below in the traveling direction by the infrared sensor 38 during flight. Then, when the infrared sensor 38 detects an area where the temperature is relatively high, the unmanned aerial vehicle 30 temporarily stops above the area. The suspension of the unmanned aerial vehicle 30 is included in the flight of the unmanned aerial vehicle 30. When the unmanned aerial vehicle 30 is a drone, the pause means hovering.

As shown in FIG. 7, the infrared sensor 38 has a predetermined visual field range W, which is a range in which an image can be captured, and a planar view of the visual field range W is a viewing angle θw. In addition, the angle formed by the straight line drawn from the position of the infrared sensor 38 of the unmanned aerial vehicle 30 directly below and the optical axis direction O which is the direction of the center of the visual field range W is defined as a sensor angle θd. The infrared sensor 38 can measure the distance between itself and a heat source such as the human body H along the optical axis direction O. Here, if the distance between the infrared sensor 38 and the human body H along the optical axis direction O is “P”, the distance D between the infrared sensor 38 and the human body H can be represented by the product of the distance P and sin θd.

The aircraft control unit 33 of the second embodiment holds information on the sensor angle θd and acquires the distance P from the infrared sensor 38. Then, the aircraft control unit 33 obtains the distance D using the obtained distance P and the sensor angle θd. In addition, the flying body control unit 33 knows the moving speed of the unmanned aerial vehicle 30, and from the relationship between the moving speed of the unmanned aerial vehicle 30 and the distance D, until the unmanned aerial vehicle 30 is directly above the human body H. Time t is calculated. That is, when the flying body control unit 33 detects a place where the temperature is relatively high such as the human body H in the optical axis direction O, the time t is obtained using the distance P and the sensor angle θd, and the obtained time t is When the time has elapsed, the unmanned aerial vehicle 30 is suspended.

By the way, when temporarily stopping during flight, the flight control unit 33 becomes unstable due to the influence of inertial force, and thus it may be difficult to stop the flight control section 33 right above the human body H with high accuracy. Therefore, for example, when the aircraft control unit 33 detects a place having a relatively high temperature in the optical axis direction O as shown in FIG. 7 or a place having a relatively high temperature as shown in FIG. When entering the range W, the unmanned aerial vehicle 30 may be decelerated. However, the flying body control unit 33 may gradually decelerate the unmanned aerial vehicle 30 or may gradually decelerate it.

The method of temporarily stopping the unmanned aerial vehicle 30 just above a place where the temperature is relatively high, such as the human body H, is not limited to the above example. FIG. 9 is an explanatory diagram showing another example of a state in which a human body is within the visual field range of the infrared sensor provided in the unmanned aerial vehicle according to the second embodiment of the present invention. FIG. 10 is an explanatory diagram showing an example of a state in which a human body is out of the visual field range of the infrared sensor of FIG.

By adjusting the angle of the infrared sensor 38, the visual field range W of the infrared sensor 38 may be adjusted as shown in FIGS. 9 and 10. That is, the visual field range W and the sensor angle θd may be adjusted so that when the human body H or the like comes out of the visual field range W, the unmanned aerial vehicle 30 is located right above the human body H or the like. In this case, the flying body control unit 33 may decelerate the unmanned aerial vehicle 30 when the human body H enters the visual field range W and temporarily stop the unmanned aerial vehicle 30 when the human body H exits from the visual field range W. Good.

FIG. 11 is an explanatory diagram illustrating a case where a human body exists in the optical axis direction of the infrared sensor provided in the unmanned aerial vehicle according to the second embodiment of the present invention. FIG. 12 is an explanatory diagram illustrating a state in which the optical axis direction of the infrared sensor of FIG. 11 is directed right below.

When a relatively high temperature place such as the human body H exists in the optical axis direction O, the flying body control unit 33 matches the moving speed of the unmanned aerial vehicle 30 with the direction opposite to the moving direction of the unmanned aerial vehicle 30. Alternatively, the infrared sensor 38 may be moved in the optical axis direction O. In this way, as shown in FIGS. 11 and 12, the optical axis direction O of the infrared sensor 38 follows the human body H and the like. Therefore, if the flying body control unit 33 temporarily stops the unmanned aerial vehicle 30 when the optical axis direction O of the infrared sensor 38 is directed downward, the unmanned aerial vehicle 30 is temporarily stopped immediately above the human body H or the like. It will be. Of course, in this case, the flying body control unit 33 also detects the human body H or the like in the optical axis direction O of the infrared sensor 38, or when the human body H or the like enters the visual field range W, the unmanned flying body 30. May be slowed down.

By the way, in the above description, the case where the unmanned aerial vehicle 30 in flight detects the temperature of the region obliquely below in the traveling direction by the infrared sensor 38 is exemplified, but the present invention is not limited to this. If the unmanned aerial vehicle 30 can temporarily stop when the human body H or the like is detected in the optical axis direction O, the unmanned aerial vehicle 30 detects the temperature of the region directly below by the infrared sensor 38. Good.

Also in the second embodiment, it is possible to combine the temporary stop of the unmanned aerial vehicle 30 and the air conditioning control such as the angle control of the upper and lower flaps and the left and right louvers of the indoor unit 10. For example, the air conditioning system 100 can be adjusted so that air is blown from the indoor unit 10 toward the unmanned air vehicle 30 that is temporarily stopped. With this configuration, the airflow from the indoor unit 10 toward the unmanned aerial vehicle 30 can be bent downward at a right angle at the position of the unmanned aerial vehicle 30, so that the air blown from the indoor unit 10 is sent to a target location. be able to. During the heating operation, a relatively low temperature region may be detected, and relatively warm air may be sent to the detected region by temporarily stopping the unmanned aerial vehicle 30 or controlling the wind direction of the indoor unit 10. Other configurations and operations are the same as those in the first embodiment.

As described above, the air conditioning system 100 according to the second embodiment performs the air conditioning of the air conditioning space S using the position information and the temperature information acquired from the unmanned air vehicle 30 as a pair of information. Therefore, since the three-dimensional temperature state of the air-conditioned space S can be grasped, the comfort of the air-conditioned space S can be improved. Further, the unmanned aerial vehicle 30 of the second embodiment is provided with an infrared camera, and the air conditioner control unit 43 uses the image captured by the infrared camera for air conditioning of the air conditioning space S. Therefore, a location having a relatively high temperature such as the human body H can be detected from a position higher than the human body H, and the detected data can be used for the air conditioning of the air conditioning space S. Furthermore, if an infrared camera is used to detect temperature information, the unmanned aerial vehicle 30 can be kept at a position higher than the human body H. Therefore, contact or collision between the human body H and the unmanned aerial vehicle 30 can be avoided, so that a failure of the unmanned aerial vehicle 30 can be avoided and safety can be improved.

Then, the unmanned aerial vehicle 30 of the second embodiment detects the temperature of the lower or diagonally lower region by the infrared camera, and when it detects the region of relatively high temperature, pauses above the region. It's a drone. Here, due to its characteristics, the drone has its body floated by blowing downward air, so that a downward airflow is generated just below the drone. Therefore, the wind can be sent to a place where the temperature is relatively high, such as the human body H, and the air can be circulated, so that the occurrence of temperature unevenness can be suppressed and the comfort of the user can be improved. In other words, by continuing to blow the air above to the lower side by hovering the drone, the drone can function as a mobile circulation, so that the temperature uniformity of the air-conditioned space S can be improved.

In addition, the air conditioner control unit 43 controls the indoor unit 10 to blow air toward the unmanned aerial vehicle 30 that is temporarily stopped. Therefore, air suitable for alleviating the temperature unevenness can be sent below the unmanned aerial vehicle 30. Other effects are similar to those of the first embodiment described above.

Here, the air conditioning system 100 uses the temperature detected by the temperature detection unit 32b provided in the aircraft body 30A and the image captured by the infrared camera that captures the lower portion of the aircraft body 30A, and temporarily operates the unmanned aircraft 30. You may judge the necessity of stop. For example, the flying body control unit 33 obtains a temperature difference between the temperature detected by the temperature detecting unit 32b and the temperature below the flying body 30A included in the image captured by the infrared camera, and the temperature difference is larger than the determination temperature. Alternatively, the unmanned aerial vehicle 30 may be suspended. With this configuration, a temperature difference in a range wider than the visual field range W in the vertical direction can be used for the determination regarding the level of the temperature, so that a more three-dimensional air state is reflected in the air conditioning of the air conditioning space S. be able to.

<Modification 2-1>
In the above description, the process in which the unmanned aerial vehicle 30 pauses immediately above a place where the temperature is relatively high has been described. However, in general, the cold air collects downward and the warm air collects upward, so that the temporary suspension of the unmanned aerial vehicle 30 directly above the human body H or the like does not always improve comfort. Therefore, the air conditioning system 100 of the present modification 2-1 suspends the unmanned aerial vehicle 30 at a position that is horizontally deviated by a set distance from directly above the human body H or the like.

That is, since the unmanned aerial vehicle 30 flies at a position higher than that of the human body H, when the unmanned aerial vehicle 30 is temporarily stopped, a wind that is warmer than that around the human body H is blown below the unmanned aerial vehicle 30. Therefore, the unmanned aerial vehicle 30 that is temporarily stopped may give the human body H discomfort. Further, when relatively warm air is sent from the sky to a place where the temperature is relatively high, the temperature at that place cannot always be lowered.

From such a viewpoint, the flying body control unit 33 of the present modification 2-1 decelerates the unmanned flying body 30 when the human body H or the like enters the visual field range W, as shown in FIG. In addition, when the human body H or the like is detected in the optical axis direction O, the unmanned aerial vehicle 30 is temporarily stopped. In this way, the wind blown downward from the unmanned aerial vehicle 30 hits the floor or the like to generate an updraft, and air having a relatively low temperature near the floor or the like is sent to the human body H or the like from below. become. Therefore, the comfort of the human body H can be improved. Further, the air in the place having the relatively high temperature can be pushed by the air having the relatively low temperature and circulated in the air-conditioned space S.

As described above, the unmanned aerial vehicle 30 of the present modification 2-1 detects the temperature of the lower or diagonally lower region with the infrared camera, and when detecting the region of relatively high temperature, moves above the region. It is a drone that pauses horizontally at a set distance from. Here, the set distance is set according to the field of view W of the infrared camera, the optical axis direction O, and the like. Therefore, it is possible to send air having a relatively low temperature to a place having a relatively high temperature, so that temperature unevenness can be mitigated.

Embodiment 3.
FIG. 13 is a block diagram illustrating a functional configuration and the like of the indoor unit according to Embodiment 3 of the present invention. Since the overall configuration of the air conditioning system in the present third embodiment is the same as in the first and second embodiments, the same components as those in the first and second embodiments will be designated by the same reference numerals and description thereof will be omitted. ..

In the air conditioning system 100 according to the third embodiment, the infrared sensor 420 is mounted on the indoor unit 10. The infrared sensor 420 captures the temperature distribution of the air-conditioned space S as an image, and outputs the captured image to the air conditioner control unit 43 as first image data. The air conditioner control unit 43 analyzes the first image data acquired from the infrared sensor 420 and extracts the human body H and an object that may be the human body H.

For example, when a part of the human body H is hidden by a chair or the like when viewed from the indoor unit 10 side, in the first image data by the infrared sensor 420, the element for distinguishing from the human body H is missing, and It cannot be specified that there is. Therefore, the air conditioner control unit 43 extracts, as an object that may be the human body H, an element including an element for identifying the human body H. The condition for extracting as an object with a possibility of the human body H may be determined by the number of elements for distinguishing from the human body H, or each element is weighted and determined by the size of the converted numerical value. May be.

When the air-conditioner control unit 43 extracts an object that may be the human body H, the air-conditioner control unit 43 sends a survey command to the aircraft control unit 33 of the unmanned aerial vehicle 30 to inspect the extracted object. The survey command includes data on the position of the extracted object. When a plurality of objects that may be the human body H are extracted, the air conditioner control unit 43 instructs the flight object control unit 33 to investigate each object by the investigation command. In this case, the survey command includes data on the positions of the extracted objects.

In response to the investigation command, the flying body control unit 33 takes an image of an object having a possibility of the human body H from the angle different from the indoor unit 10 side by the infrared sensor 38, and sets it as the second image data as the air conditioner control unit 43. Send to. The second image data may be one or plural. The air conditioner control unit 43 analyzes the second image data and determines whether or not an object that may be the human body H is the human body H.

Here, when the human body H is extracted from the first image data, the air conditioner control unit 43 executes the air conditioning control based on the preset control content. For example, when the wind is set to be sent directly to the human body H, the air conditioner control unit 43 controls the angles of the upper and lower flaps and the left and right louvers of the indoor unit 10 so that the human body H is exposed to the wind. Adjust to. On the other hand, when the setting is such that the wind is not directly applied to the human body H, the air conditioner control unit 43 controls the vertical flaps of the indoor unit 10 and the angles of the left and right louvers, and the human body H is exposed to the wind. Adjust so that it does not exist. When it is determined from the second image data that the object that may be the human body H is the human body H, the air conditioner control unit 43 performs the same process as when the human body H is extracted from the first image data.

Other configurations and operations are the same as those in the first embodiment. Further, the structure of the third embodiment can be combined with the structure of the second embodiment. That is, when the human body H is extracted from the first image data and the second image data, the air conditioner control unit 43 may suspend the unmanned aerial vehicle 30 immediately above the human body H or near the human body H.

As described above, the air conditioning system 100 according to the third embodiment performs the air conditioning of the air conditioning space S using the position information and the temperature information acquired from the unmanned air vehicle 30 as a pair of information. Therefore, since the three-dimensional temperature state of the air-conditioned space S can be grasped, the comfort of the air-conditioned space S can be improved. The indoor unit 10 also includes an infrared sensor 420 that captures the temperature distribution of the air-conditioned space S as an image and sends the captured image as first image data to the air conditioner control unit 43. When extracting an object that may be the human body H from the first image data, the air conditioner control unit 43 causes the unmanned aerial vehicle 30 to fly to the position of the extracted object, and displays the image captured by the infrared camera at that position. It is acquired as the second image data. Then, the air conditioner control unit 43 determines from the second image data whether or not the object that may be the human body H is the human body H. Therefore, the air conditioner control unit 43 can send air that meets the needs to the position of the human body H by temporarily stopping the unmanned aerial vehicle 30 or controlling the wind direction of the indoor unit 10.

The above-described respective embodiments are preferable specific examples in the air conditioning system, and the technical scope of the present invention is not limited to these aspects. For example, in each of the above embodiments, the case where the position information is detected by the infrared sensor 38 and the gyro sensor 39 is illustrated, but the present invention is not limited to this. The air conditioning system 100 may acquire position information indicating the position of the unmanned aerial vehicle 30 using GPS (Global Positioning System) or the like. In this case, the unmanned aerial vehicle 30 may be provided with a GPS transmitter as the position detecting means 32a. Further, the position detection means 32a may employ a communication means that performs wireless communication according to a communication standard such as RFID (Radio Frequency IDentifier) or Bluetooth. Further, the position detecting means 32a may detect the position information by using the marker (mark) and the image captured by the camera. In this case, for example, the markers may be arranged at the corners, walls, or the ceiling of the air-conditioned space S, and the position detection unit 32a may detect the position information from the positions of the markers in the image captured by the camera. In addition, the position detection unit 32a may be one that connects the images picked up by the cameras and uses them. Further, the position detection means 32a may be one that detects position information by combining a pressure sensor and a Hall effect sensor that picks up magnetic flux. In this case, the position detecting means 32a detects the difference in atmospheric pressure from the measurement data of the pressure sensor and estimates the height. In each of the above embodiments, the infrared sensor is illustrated as the sensor for detecting the human body H, but the sensor is not limited to this, and a sensor for detecting the human body by ultrasonic waves or visible light may be used.

Although the case where the unmanned aerial vehicle 30 communicates with the indoor unit 10 each time the position information and the temperature information are detected has been described in each of the above embodiments, the present invention is not limited to this. For example, the flight control unit 33 causes the internal memory or the like to store position information and temperature information at each position in one flight process in association with each other, and when the unmanned air vehicle 30 returns to the power feeding base unit 15, The accumulated data may be collectively transmitted to the air conditioner control unit 43. By doing so, it is possible to reduce power consumption due to communication. If the unmanned aerial vehicle 30 is separated from the power feeding base unit 15 for a relatively short period of time, there is little demerit from the viewpoint of reflecting the accumulated data on the air conditioning. When such a configuration is adopted, communication between the unmanned aerial vehicle 30 and the indoor unit 10 may be performed by short-range wireless communication such as NFC (Near Field Communication).

Here, the indoor unit 10 in each of the above embodiments corresponds to an "air conditioner". By the way, when the air conditioning system 100 is configured to include a plurality of indoor units 10 and one or a plurality of outdoor units 20 and has a system controller that comprehensively manages the entire system, the system controller is referred to as a remote controller 80. You may make it function similarly. In addition, in each of the above-described embodiments, the air conditioning system 100 in which the indoor unit 10 and the outdoor unit 20 are provided as separate bodies has been illustrated, but the present invention is not limited to this, and the air conditioning system 100 includes the function of the indoor unit 10 and the outdoor unit. You may have the "air conditioner" which has the function of the machine 20 together.

Although the indoor unit 10 for home use is illustrated in FIG. 1, the indoor unit 10 is not limited to this, and the indoor unit 10 is a ceiling-embedded cassette type 4-direction indoor unit or a ceiling-embedded cassette type 2 that constitutes a packaged air conditioner (PAC). Direction indoor unit, or a ceiling-embedded cassette type one-way indoor unit. In this case, since the indoor unit 10 is embedded in the ceiling, the unmanned aerial vehicle 30 may return to the home using, for example, an automatic filter cleaning unit provided on the suction grill of the suction port. That is, the power feeding base portion 15 capable of returning to the home when the filter descends may be provided inside the main body 10A and outside the filter, and the unmanned air vehicle 30 may return to the home by lowering the filter. In addition, the power supply base 15 made of a material with a magnet is provided in a part of the main body 10A, an electromagnet is mounted on the unmanned aerial vehicle 30, and when the unmanned aerial vehicle 30 returns home, the electromagnet is energized so that the unmanned aerial vehicle 30 is It may be fixed to the power feeding base portion 15. Further, an opening/closing type storage door may be provided below the main body 10A, and the power feeding base 15 may be provided inside the main body 10A and adjacent to the storage door.

By the way, in each of the above-described embodiments, the case where the unmanned aerial vehicle 30 is charged only by the power feeding base unit 15 is illustrated, but the present invention is not limited to this. For example, a charging station capable of non-contact charging may be provided on the desk or at the bedside of the bedroom so that the unmanned aerial vehicle 30 can be charged at a place other than the power feeding base unit 15.

In each of the above embodiments, the drone including the four motors 35 and the propellers 36 is illustrated as the unmanned aerial vehicle 30, but not limited to this, the unmanned aerial vehicle 30 includes five or more motors 35 and the propellers 36. It can be a drone. In the above description, the drone is illustrated as the unmanned aerial vehicle 30, but the drone is not limited to this. For example, the unmanned aerial vehicle 30 may be an airship. Here, the airship levitates the airframe by an air bag filled with a gas having a smaller specific gravity than air, and flies by a power unit. Then, the airship changes the amount of air in the air chambers provided in the front and rear of the air bag to maintain the balance in the front-rear direction. In addition, the airship moves vertically by adjusting the amount of air in each air chamber. Therefore, when an airship is adopted as the unmanned air vehicle 30, the air vehicle control unit 33 controls the power unit, the air chamber, and the like. However, the unmanned aerial vehicle 30 may have a helicopter shape or a balloon shape.

The unmanned aerial vehicle 30 may have a homing function of returning to a fixed position such as the power feeding base portion 15 at the time of contact with an obstacle, dropping, or part replacement. For example, the flying body control unit 33 may detect contact or fall with an obstacle from the information acquired from the gyro sensor 39. In addition, the flight control unit 33 records information such as a manufacturing date, a continuous drive time, and the number of times of charging in an internal memory or the like, and predicts a component replacement time, that is, a replacement time of each component from the recorded data. Good to do.

In each of the above embodiments, the case where the air conditioning system 100 has one unmanned aerial vehicle 30 has been exemplified, but the present invention is not limited to this, and the air conditioning system 100 may have a plurality of unmanned aerial vehicles 30. .. With this configuration, the temperature information at many positions can be collected quickly, so that the efficiency of air conditioning control can be improved. In particular, if the air-conditioned space S is a large venue, the merit will be greater. In addition, since it is possible to reduce the time when three-dimensional temperature information cannot be acquired, such as when another unmanned aerial vehicle 30 is flying while one unmanned aerial vehicle 30 is being charged, each air-conditioned space S or each user can be reduced. The comfort of can be further enhanced. It should be noted that the plurality of unmanned aerial vehicles 30 may return to the power feeding base section 15 in order, or the power feeding base section 15 and the control unit 40 may be configured so that the plurality of unmanned aerial vehicles 30 can return to the home. Good. Here, in each of the above-described embodiments, an example in which the power feeding base portion 15 and the power supply portion 41 are separately configured has been shown, but the present invention is not limited to this, and the power feeding base portion 15 may be a part of the main body portion 10A. It may be configured by the power supply unit 41.

The unmanned aerial vehicle 30 may have a homing function of returning to a fixed position such as the power feeding base portion 15 at the time of contact with an obstacle, dropping, or part replacement. For example, the flying body control unit 33 may detect contact or fall with an obstacle from the information acquired from the gyro sensor 39. In addition, the flight control unit 33 records information such as a manufacturing date, a continuous drive time, and the number of times of charging in an internal memory or the like, and predicts a component replacement time, that is, a replacement time of each component from the recorded data. Good to do.

In each of the above-described embodiments, the temperature detecting means 32b and the infrared sensor are used to exemplify the sensors for detecting the temperature. However, the present invention is not limited to this. May be By doing so, information on the humidity in the vicinity of the unmanned aerial vehicle 30 can also be transmitted to the air conditioner control unit 43. Therefore, the air conditioner control unit 43 can perform air conditioning in consideration of the humidity of the air-conditioned space S, and can improve comfort. However, the sensor unit 32 may include a CO ₂ sensor that detects the carbon dioxide concentration. As described above, by using the measurement data from the humidity sensor or the CO ₂ sensor, it is possible to accurately improve the stagnation of the air generated in the air-conditioned space S.

In FIG. 3, the lower button 37a and the upper button 37b are illustrated as the operation buttons of the operation unit 37, but the operation buttons are not limited thereto. The operation unit 37 may have, for example, a selection button for instructing selection of the detection mode. Further, the unmanned aerial vehicle 30 may be provided with a display unit including, for example, a liquid crystal display (LCD), and may have a function of remotely operating the air conditioning system 100, like the remote controller 80. However, the unmanned aerial vehicle 30 may be configured to have a touch panel, and the touch panel may function similarly to the operation unit 37 and the display unit.

Note that in wireless communication between the unmanned aerial vehicle 30 and the indoor unit 10, WiFi or Bluetooth, which is a standard for wireless communication, can be used. What kind of standard is used depends on the size of the air-conditioned space S. It may be decided by the following. For example, when the air conditioning system 100 is installed in a relatively large place such as a large-scale hall, it is possible to exceed the transmittable distance in Bluetooth, so it is preferable to mainly use WiFi.
