The control server 10, the wind speed sensor 20, and the ventilation device 50 are communicatively connected to each other by wireless communication or wired communication. For example, the control server 10, the wind sensor 20, and the ventilation device 50 may be communicatively connected via a network (not shown).

In this embodiment, the function of one control server 10 may be realized by a set of multiple pieces of hardware. The method of distributing a plurality of functions required to implement the control server 10 according to this embodiment to one or a plurality of pieces of hardware depends on the processing capability of each piece of hardware and/or the specifications required for the control server 10. can be determined as appropriate in view of the above.

The control server 10 shown in FIG. 1 is a device that controls a ventilation device 50, which will be described later. The control server 10 receives an input of an operation instruction from a user or an input of sensing data from various sensors, and determines the control amount of the ventilation device 50 .
The control server 10 generates a control signal according to the determined control amount of the ventilation device 50 and transmits the control signal to the ventilation device 50 .
The control server 10 may be realized by, for example, a stationary PC (Personal Computer) or a laptop PC.

As shown in FIG. 1, the control server 10 includes a communication IF (Interface) 12, an input device 13, an output device 14, a memory 15, a storage 16, and a processor 19.
The input device 13 is a device (for example, a remote controller, etc.) for receiving an input operation from a user.

The output device 14 is a device that outputs information from the control server 10 to the outside.
The output device 14 includes a display device (display, speaker, etc.) for displaying the operating state of the ventilation system 1 to the user.

The control server 10 is configured by a computer having an arithmetic device and a storage device. The basic hardware configuration of the computer and the basic functional configuration of the computer realized by the hardware configuration will be described later. Regarding the control server 10, description overlapping with the basic hardware configuration of the computer and the basic functional configuration of the computer, which will be described later, will be omitted.

The wind sensor 20 is a sensor that senses the strength of airflow (wind). For the wind speed sensor 20, for example, various anemometers listed below can be adopted.
・Hot-wire anemometer: A structure that converts the change in heat by receiving wind into wind speed by using a resistor that changes its resistance value with heat, which is built into the tip of the sensor ・Vane-type anemometer: Vane ( A structure that receives wind from a windmill) and converts the number of rotations of the vanes into wind speed ・Pitot tube type anemometer: A structure that converts the differential pressure generated in the pitot tube into wind speed In this explanation, the vane type anemometer is taken as an example. to explain.

The wind sensor 20 transmits sensing data to the control server 10 using a communication standard such as short-range wireless communication. At this time, the wind sensor 20 may transmit sensing data to the control server 10 via the network.
The wind speed sensor 20 senses the wind speed based on a predetermined measurement frequency such as every few seconds. The wind sensor 20 transmits the data to the control server 10 every time it acquires new sensing data. The measurement frequency of the wind speed sensor 20 can be set arbitrarily.

The ventilation device 50 is a device that is installed in a building and takes in outside air into the building. Ventilation device 50 serves as an air inlet or outlet. Ventilation device 50 is positioned over a vent formed through the wall of the building. The vent may be formed in the ceiling or floor of the building. Activation of the vent device 50 controls the amount of air flow through the vent. The operation of the ventilation device 50 refers to the opening and closing of the ventilation device 50 accompanying the operation of the louver 51, which will be described later.

The ventilation device 50 mainly includes a plurality of louvers 51 and actuators 52 .
The louver 51 has a blade shape. A plurality of louvers 51 are arranged side by side so as to cover the vent, thereby shielding the vent.
The louver 51 operates as the actuator 52 is driven. As each of the louvers 51 moves, a gap is formed between adjacent louvers 51 . This opens the vent device 50 and allows air flow between the exterior and interior of the building through the vents. The size of the gap formed in the entire ventilation device 50 due to the operation of the louver 51 is referred to as the opening degree of the ventilation device 50 .
A specific mode of operation of the louver 51 will be described later.

The actuator 52 is a driving device that operates the louver 51 based on control signals sent from the control server 10 .
The actuator 52 mainly includes a drive section that operates the louver 51 and a guide section that supports the louver 51 and guides the movement of the louver 51 as the motor drives.

FIG. 2 is a schematic diagram showing the interior of a house 100 in which the ventilation system 1 is actually used. In addition, in FIG. 2, the appearance of the house 100 is simplified.
As shown in FIG. 2, the wall of the house 100 is provided with a window 40 and a pair of ventilation devices 50A, 50B. A pair of ventilation devices 50A, 50B are provided on a pair of opposing walls, respectively. Thus, the pair of venting devices 50A, 50B act as an air inlet and an air outlet. That is, by opening the pair of ventilation devices 50A and 50B together, an air flow path is formed in the living room of the house 100 even if the window 40 is closed.

In the illustrated example, the supplied air As enters the living room from the ventilation device 50A on the left side, flows mainly along the flow path Fc in the living room, and then is discharged from the ventilation device 50B on the right side toward the buying section as exhaust Ex. exhausted. Thus, it is desirable to have a pair of ventilation devices 50 . This facilitates formation of an air flow in the living room.

Two wind speed sensors 20 are provided inside the house 100 . Wind sensor 20 is arranged on the ceiling of house 100 . The wind speed sensors 20 are arranged side by side along the flow path Fc inside the flow path Fc formed in the living room of the house 100 . That is, the wind speed sensor 20 is arranged at intervals along the flow path Fc between one and the other of the pair of ventilation devices 50 in the room of the house 100 . In addition, the place where the wind speed sensor 20 is arranged can be arbitrarily changed in the living room.

FIG. 3 is a view of the ventilation device 50A viewed from the inside of the house 100 (as viewed in the X direction in FIG. 2).
As shown in FIG. 3, above the window 40 in the wall surface, a vent K is formed through the wall. In the illustrated example, the vent K has a rectangular shape that is longer in the horizontal direction than in the vertical direction. The shape of the vent can be changed arbitrarily. For example, the vent K may have a rectangular shape that is longer in the vertical direction than in the horizontal direction. Also, the vent K may be provided below or on the side of the window 40 .

The vent device 50A is arranged to cover the vent K. A plurality of louvers 51 in the ventilation device 50A are arranged side by side in the vertical direction so as to cover the ventilation opening K. As shown in FIG.
Actuator 52 is provided inside the wall near louver 51 .
The shape and position of the louver 51 can be changed according to the shape and position of the vent K.

FIG. 4 is a diagram (as viewed in the Y direction in FIG. 2) for explaining the opening and closing operation of the louver 51 in the ventilation device 50A. Note that illustration of the actuator 52 is omitted in this figure. Also, in this description, the X direction shown in FIG. 4 is referred to as the front-rear direction.

In the example shown in FIG. 4, the plurality of louvers 51, which are louvers 51, are arranged such that adjacent ones in the vertical direction are arranged at different positions in the front-rear direction. When the actuator 52 is driven, the louver 51 positioned on one side in the front-rear direction among the louvers 51 adjacent to each other slides upward, thereby forming a gap between the louvers 51 . Outside air enters the living room through this gap as supplied air As. The same is true when the ventilation device 50 functions as an exhaust port.

FIG. 5 is a diagram (as viewed in the Y direction in FIG. 2) explaining another example of the opening/closing operation of the louver 51. As shown in FIG. Note that illustration of the actuator 52 is omitted in this figure. Also, in this description, the X direction shown in FIG. 4 is referred to as the front-rear direction.

In the example shown in FIG. 5, all the louvers 51 are arranged at the same position in the front-rear direction X. As shown in FIG. As the actuators 52 are driven, the louvers 51 are rotated about their ends (upper ends) to form gaps between the louvers 51 . Outside air enters the living room through this gap as supplied air As. The same is true when the ventilation device 50 functions as an exhaust port.
The opening and closing operation of the louvers 51 described above is merely an example, and can be arbitrarily changed as long as a gap is formed between the plurality of louvers 51 as the actuators 52 are driven.

<1.1 Configuration of Control Server 10>
FIG. 6 is a block diagram showing the functional configuration of the control server 10 shown in FIG. 1. As shown in FIG.
As shown in FIG. 6 , the control server 10 includes a communication section 120 , an input device 13 , an output device 14 , a storage section 180 and a control module 190 . Each block included in the control server 10 is electrically connected by, for example, a bus.

The communication unit 120 performs processing such as modulation/demodulation processing for the control server 10 to communicate with other devices. The communication unit 120 performs transmission processing on the signal generated by the control module 190 and transmits the signal to the outside (for example, the ventilation device 50). The communication unit 120 performs reception processing on signals (eg, various sensing data) received from the outside, and outputs the signals to the control module 190 .

The input device 13 is a device for a user who operates the control server 10 to input instructions. The input device 13 is implemented by, for example, a remote controller 131 or the like through which instructions are input by operating input keys. As the input device 13, other equipment such as a touch-sensitive device that inputs an instruction by touching the operation surface may be provided.

The input device 13 converts an instruction input by the user into an electrical signal and outputs the electrical signal to the control module 190 . Note that the input device 13 may include, for example, a receiving port for receiving an electrical signal input from an external input device.

The output device 14 is a device for presenting information to the user who operates the control server 10 . The output device 14 is implemented by, for example, the display 141 or the like. The display 141 displays data indicating the operational status of the control module 190 . The display 141 is implemented by, for example, an LCD (Liquid Crystal Display) or an organic EL (Electro-Luminescence) display.

The storage unit 180 is implemented by, for example, the memory 15 and the storage 16, and stores data and programs used by the control server 10. FIG. Storage unit 180 further stores control model 181 .

The control model 181 is a model used when determining the control amount of the ventilation device 50 . The control model 181 is obtained by causing a machine learning model to perform machine learning according to a model learning program based on learning data.

For example, the control model 181 is learned to output the opening degree (control amount) of the ventilation device 50 with respect to input sensing data regarding the wind speed. Here, the amount of movement of the louver 51 can be set based on the degree of opening of the ventilation device 50 .
At this time, the data for learning uses, for example, the wind speed in the living room as input data, and the opening degree of the ventilation device 50 with respect to the input value as the correct output data.

The control model 181 is allowed to input a plurality of wind speed sensing data. At this time, the control model 181 determines that all the sensing data (that is, the wind speed in the living room) obtained after this control from each of the plurality of wind speed sensors 20 as the degree of opening of the ventilation device 50 is within a predetermined range. Output the opening. Here, it is desirable that the "within a predetermined range" is, for example, a strength that is higher than the minimum strength at which a person in the living room can perceive the wind and that does not interfere with the person in the living room.

In addition, the control model 181 determines that the average value of the sensing data (that is, the wind speed in the living room) acquired from each of the plurality of wind speed sensors 20 after this control as the degree of opening of the ventilation device 50 is within a predetermined range. The degree of opening may be output. In this case, it is permissible for the living room to have a localized location where the wind is weak or strong.

The control model 181 according to the present embodiment is, for example, a synthetic function with parameters obtained by synthesizing a plurality of functions. A parameterized composite function is defined by a combination of multiple tunable functions and parameters. The control model 181 according to this embodiment may be any parameterized composite function that satisfies the above requirements, but is assumed to be a multi-layered network model (hereinafter referred to as a multi-layered network). A control model 181 using a multi-layered network has an input layer, an output layer, and at least one intermediate layer or hidden layer provided between the input layer and the output layer. Control model 181 is envisioned for use as a program module that is part of artificial intelligence software.

As the multi-layered network according to the present embodiment, for example, a deep neural network (DNN), which is a multi-layered neural network targeted for deep learning, can be used. As the DNN, for example, a convolution neural network (CNN) targeting images may be used.
Moreover, the above is merely an example of the control model 181, and the control model 181 may have other configurations. For example, the control model 181 may be a rule-based model described by a function in which the wind speed in the living room is set as a variable and each variable is assigned a coefficient derived from past performance.

Control module 190 is implemented by processor 19 reading a program stored in storage unit 180 and executing instructions included in the program. The control module 190 controls operations of the control server 10 . The control module 190 functions as a reception module 191, a control amount determination module 192, a signal generation module 193, and an output module 194 by operating according to a program.

The receiving module 191 performs processing for acquiring instructions input from the input device 13 or sensing data input from various sensors. Specifically, for example, the receiving module 191 acquires an instruction input by the user to the remote controller 131 . The receiving module 191 also acquires sensing data transmitted from the wind speed sensor 20 .

The control amount determination module 192 determines the control amount of the ventilation device 50 (the operation amount of the louver 51). Specifically, the control amount determination module 192 determines the control amount from the opening degree of the ventilation device 50 output from the control model 181 by inputting sensing data relating to the wind speed to the control model 181 . The controlled variable determination module 192 outputs the determined controlled variable to the signal generation module 193 .

The signal generation module 193 generates a control signal to be input to the ventilation device 50 based on the control amount input from the control amount determination module 192 .

The output module 194 outputs the control signal generated by the signal generation module 193 to the ventilation device 50 .
The output module 194 outputs data indicating the operating state of the control module 190 to the display 141 .

<2 System 1 processing>
Next, processing of the ventilation system 1 will be described.
FIG. 7 is a flow chart showing an example of processing of the ventilation system 1 .
In this description, the processing is started with the ventilation device 50 opened according to an operation instruction input from the user to the remote controller 131 .

First, the wind speed sensor 20 senses the wind speed in the living room (step S101).
Specifically, each of the plurality of wind speed sensors 20 senses the wind speed in the living room. Wind speed sensing is repeatedly performed according to a preset measurement frequency. Therefore, the subsequent processing is also repeatedly performed according to acquisition of new sensing data.

After step S101, the wind sensor 20 transmits the acquired sensing data to the control server 10 (step S102).
Specifically, each of the plurality of wind speed sensors 20 transmits the acquired sensing data to the control server 10 .

After step S102, the control server 10 acquires sensing data transmitted from the wind speed sensor 20 (step S201).
Specifically, the receiving module 191 of the control server 10 receives the sensing data transmitted from the plurality of wind speed sensors 20 respectively.

After step S201, the control server 10 generates a control signal (step S202).
Specifically, the control amount determination module 192 of the control server 10 inputs the sensing data regarding the wind speed to the control model 181, and determines the control amount from the opening degree of the ventilation device 50 output from the control model 181. .
Then, the signal generation module 193 of the control server 10 generates a control signal to be input to the ventilation device 50 based on the control amount input from the control amount determination module 192 . This control signal controls the opening of the ventilation device 50 .

After step S202, the control server 10 transmits a control signal to the ventilation device 50 (step S203).
Specifically, the output module 194 of the control server 10 outputs the control signal generated by the signal generation module 193 to the ventilation device 50 .

After step S203, the ventilation device 50 receives the control signal sent from the control server 10 (step S301).

After step S301, the ventilation device 50 performs control based on the control signal (step S302).
Specifically, the ventilation device 50 is opened by driving the actuator 52 of the ventilation device 50 based on the control signal to operate the louver 51 . As a result, flow paths for supply air and exhaust air are generated in the living room.
With the above, the processing of the system 1 ends.

It should be noted that the control of the ventilation device 50 is desirably performed continuously so as to respond to changes in wind speed in the living room. That is, when the wind speed in the living room temporarily increases, such as when a gust of wind from the outside enters the living room, the ventilation device 50 is controlled to close. Moreover, when the wind speed in the living room becomes smaller than the predetermined range, the ventilation device 50 opens again, and the outside air enters the living room. By repeating this process, a wind having a strength within a predetermined range is maintained in the living room as much as possible, except when there is no wind outside.

<3. Summary>
As described above, in the system 1 according to the above embodiment, the control server 10 controls the opening degree of the ventilation device 50 using sensing data from the wind speed sensor 20 that senses the wind speed in the living room. Therefore, it is possible to always control the ventilation device 50 in consideration of the strength of the wind in the living room, and it is possible to maintain a comfortable air flow in the living room.

In addition, it is possible to smoothly ventilate a building in which the opening of windows is restricted, such as a residence in a high-rise apartment building or a room in a high-rise hotel. In addition, since an air flow is formed in the living room simply by opening and closing the ventilation device 50, power consumption can be suppressed compared to a general ventilation or air conditioning system.

Further, in the system 1, the opening degree is controlled so that the sensing data acquired after control from each of the plurality of wind speed sensors 20 is within a predetermined range. Therefore, it is possible to maintain a comfortable air flow everywhere in the living room where the wind speed sensor 20 is arranged.

Further, in the system 1, the opening degree may be controlled so that the average value of sensing data acquired after control from each of the plurality of wind speed sensors 20 is within a predetermined range. In this case, it is possible to easily control the ventilation device 50 by allowing variations in local wind strength such as in the vicinity of the ventilation device 50 .

<4. Variation>
Next, a system 2 according to a modification will be described. This modification differs from the previous embodiment in the part where the presence of a person in the living room is detected and the ventilation device 50 is opened.
In the following description, the same reference numerals are given to the same parts as in the above-described embodiment. Their names and functions are also the same. Therefore, detailed descriptions of common configurations and processes will not be repeated.

<4.1 Overall Configuration of System 2>
FIG. 8 is a block diagram showing the overall configuration of a ventilation system 2 according to a modification.
As shown in FIG. 8, the system 2 according to the modification includes a human sensor 30. As shown in FIG. A human sensor 30 is provided in the living room and detects the presence of a person in the living room. The occupant sensor 30 may be configured to detect the presence of a person entering the flow path formed between the pair of ventilation devices 50 . Also, a plurality of motion sensors 30 may be arranged in the living room.

As the human sensor 30, sensors using various principles such as an infrared method, an electrostatic method, and an ultrasonic method can be adopted as long as they can detect the presence of a person. In this description, the human sensor 30 using ultrasonic waves will be described as an example. The human detection sensor 30 emits ultrasonic waves and detects changes in the propagation path by detecting changes in the time transmitted by reflecting off the walls, floors, and ceilings in the living room, thereby detecting changes in the propagation paths of people who are obstacles. Detect the presence in
The human sensor 30 is communicatively connected to the control server 10 by priority or wireless communication. Note that the human sensor 30 may be connected for communication with the control server 10 via a network.

FIG. 9 is a schematic diagram showing the inside of a house 100 in which the ventilation system 2 is actually used.
As shown in FIG. 9 , the human sensor 30 is provided on the ceiling of the house 100 . The position where the human sensor 30 is arranged can be changed arbitrarily. In the illustrated example, the human sensor 30 emits ultrasonic waves in multiple directions so as to detect the presence of people at multiple locations in the living room.
Moreover, in the system 2, one wind speed sensor 20 is provided in the living room.

<4.2 Processing of System 2>
Next, processing of the ventilation system 2 will be described.
FIG. 10 is a flow chart showing an example of processing of the ventilation system 2 .
In this description, the process begins with the ventilation device 50 closed.

First, the human sensor 30 senses the presence of a person in the living room (step S111).
Specifically, the human detection sensor 30 senses the presence of a person by radiating an ultrasonic wave into the living room and detecting a change in time transmitted by reflection in the living room. Sensing by the human sensor 30 is always performed.

After step S111, the human sensor 30 transmits the acquired sensing data to the control server 10 (step S112).

After step S112, the control server 10 acquires sensing data transmitted from the human sensor 30 (step S211).
Specifically, the reception module 191 of the control server 10 receives sensing data transmitted from the human sensor 30 .

After step S211, the control server 10 generates a control signal (step S212).
Specifically, the signal generation module 193 of the control server 10 generates a control signal for controlling the degree of opening of the ventilation device 50 . The opening degree of the ventilation device 50 at this time can be set arbitrarily.

After step S212, the control server 10 transmits a control signal to the ventilation device 50 (step S213).
Specifically, the output module 194 of the control server 10 outputs the control signal generated by the signal generation module 193 to the ventilation device 50 .

After step S213, the ventilation device 50 receives the control signal sent from the control server 10 (step S311).

After step S311, the ventilation device 50 performs control based on the control signal (step S312).
Specifically, the ventilation device 50 is opened by the actuator 52 of the ventilation device 50 operating the louver 51 based on the control signal. As a result, flow paths for supply air and exhaust air are generated in the living room.
With the above, the unique processing of the system 2 ends.
Thereafter, the above-described wind speed sensing process (step S101 in FIG. 7) is performed by the wind speed sensor 20 so as to respond to the flow of air generated in the living room due to the opening of the ventilation device 50, and the subsequent processes. are repeated in sequence.

<4.3 Summary>
As described above, in the system 2 according to the modified example, the step of opening the ventilation device 50 is executed when the presence of a person is detected by the human sensor 30 . Therefore, it is not necessary for a person in the living room to open the ventilation device 50 according to an operation instruction, and user convenience can be improved.

In addition, when the human sensor 30 detects the presence of a person who has entered the flow path formed in the living room, the person who has entered between the pair of ventilation devices 50 in the living room is supplied with comfortable air. can provide a flow of

Moreover, in the system 2, the ventilation device 50 may be closed when the human sensor 30 no longer detects the presence of a person in the living room, similarly to the process described above. In this case, when a person in the living room leaves the room, there is no need to close the ventilation device 50 by an operation instruction, which can further enhance user convenience.

<5. Other modified examples>
The system 1 may also include various other sensors installed inside the living room or outside the building. Examples of sensors include the following.
・Temperature sensor ・Humidity sensor ・Sunlight sensor ・Radiant heat sensor ・Dust sensor ・Wind speed sensor (installed outside the building)
In this case, the control model 181 is learned to output the optimum opening of the ventilation device 50 for each item value of the input sensing data.

In addition, the system 1 may have different degrees of opening in each of the pair of ventilation devices 50A and 50B.
Thereby, the flow of air in the living room can be more actively controlled.

Also, the system 1 may vary the ease of air flow depending on the area of the ventilation device 50 .
Specifically, when the ventilation device 50 includes, for example, a plurality of louvers 51 arranged side by side in the vertical direction, the amount of movement of the louvers 51 may differ depending on the position thereof. As a result, for example, the upper half of the ventilation device 50 and the lower half of the ventilation device 50 have different sizes of gaps between adjacent louvers 51. flowability will be different. As a result, in comparison with a configuration in which the operation amounts of the plurality of louvers 51 are set uniformly over the entire area of the ventilation device 50, it is possible to give a degree of freedom to the air flow generated in the living room.

Further, when the ventilation device 50 includes a plurality of louvers 51 arranged side by side in the vertical direction and the horizontal direction, the louvers 51 may be operated only in a part of the area to locally circulate the air. . For example, in one ventilation device 50A arranged near the floor among the wall surfaces, only the plurality of louvers 51 occupying the lower left area as seen from the living room are operated. Then, in the other ventilation device 50B arranged near the ceiling on the wall surface, only the plurality of louvers 51 occupying the upper left area as viewed from the living room are operated. As a result, the circulation of air is ensured at the opposite position to the living room, so that the air can be efficiently exchanged in the entire living room.

In addition, the system 1 may weight the sensing data of the wind speed sensor 20 according to its position. For example, among the plurality of wind speed sensors 20, the sensing data from the wind speed sensor 20 positioned outside or inside the living room in plan view may not be used for control. In addition, the system 1 performs mathematical processing such as multiplying each of the sensing data acquired from the plurality of wind speed sensors 20 by a coefficient set according to the position of the corresponding wind speed sensor 20, and the obtained living room The control amount of the ventilation device 50 may be determined based on the evaluation index related to the wind speed. In this case, the control model 181 is learned to output the optimum opening of the ventilation device 50 with the value of the evaluation index as input data.

Also, the configuration of the system 1 can be changed.
For example, as shown in FIG. 12 , in a system 3 according to a first example of another modified example, the ventilation device 50 further includes a control device 53 . In this case, the control device 53B in the ventilation device 50 has the same configuration as the control server 10 in FIG. 1 and implements the same functions.

Further, as shown in FIG. 13 , in the system 4 according to the second example of another modified example, the wind speed sensor 20 includes a sensing module 21 and a control device 22 . In this case, the control device 22 in the wind speed sensor 20 has the same configuration as the control server 10 in FIG. 1 and implements the same functions. Also, the sensing module 21 corresponds to a hardware resource in which a sensor unit for detecting wind speed is mounted.
Further, each of the ventilation device 50 and the wind speed sensor 20 may have a control device, and the respective control devices may cooperate to realize the function as the control server 10 in FIG. 1 .
