Description

The present disclosure relates to programs, methods, systems, and devices.

BACKGROUND ART Conventionally, devices that take in air from outside have been widely used for ventilation inside buildings.
For example, Patent Document 1 discloses a device that automatically adjusts the opening degree of a ventilation port depending on the strength of wind that passes through a louver and enters an air supply duct inside a building.

JP2000-179906

However, the device described in Prior Document 1 adjusts the opening degree of the ventilation port depending on the strength of the wind that has entered the air supply duct inside the building. For this reason, in the process of the wind entering the air supply duct reaching the living room, the airflow is attenuated, so that a sufficient flow of air may not be generated within the living room. In other words, with this device, there is room for improvement in maintaining a comfortable air flow for people in the living room.

An object of the present disclosure is to provide a system that can maintain comfortable air flow within a living room.

This is a program used in a computer that has a processor. The program includes the steps of: acquiring sensing data from one or more wind speed sensors that sense the wind speed inside the living room; and creating a flow path for air flowing inside the living room using the acquired sensing data; and controlling the opening degree of a plurality of ventilation devices provided as air supply ports and exhaust ports.

According to the present disclosure, it is possible to maintain a comfortable flow of air within a living room.

<Embodiment>
Embodiments of the present disclosure will be described below with reference to the drawings. In the following description, the same parts are given the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

<Summary>

Specifically, the system 1 has a function of automatically adjusting the opening degree of a ventilation device 50, which will be described later, which functions as an air supply port or an exhaust port, depending on the wind speed in a living room provided inside a building.

In the following description, the configuration of the system 1 will be explained by taking as an example a configuration applied to a general residence, but the configuration is not limited to this.
In other words, the buildings to which System 1 can be applied are not limited to general residences, but can be applied to various types of facilities such as office buildings and large commercial facilities that require internal ventilation by drawing in outside air. Can be done.

<1 Overall system configuration>
FIG. 1 is a block diagram showing the overall configuration of the system 1. As shown in FIG. A system 1 shown in FIG. 1 includes a control server 10, a wind speed sensor 20, and a ventilation device 50, and is installed in a house 100.
The control server 10, the wind speed sensor 20, and the ventilation device 50 are communicatively connected to each other by wireless or wired communication. For example, the control server 10, the wind speed sensor 20, and the ventilation device 50 may be communicatively connected via a network (not shown).

In this embodiment, the functions of one control server 10 may be realized by a collection of a plurality of hardware. How to allocate a plurality of functions required to realize the control server 10 according to this embodiment to one or more pieces of hardware depends on the processing capacity of each piece of hardware and/or the specifications required for the control server 10, etc. It 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 input of operation instructions from the user or 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 it 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 accepting input operations 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 status of the ventilation system 1 to the user.

The control server 10 is composed of a computer including a calculation 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, a description that overlaps 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 speed sensor 20 is a sensor that senses the strength of air flow (wind). For example, various anemometers listed below can be employed as the wind speed sensor 20.
・Hot-wire anemometer: A structure that uses a resistor built into the tip of the sensor whose resistance changes with heat to convert the change in heat caused by receiving wind into wind speed ・Vane-type anemometer: A vane ( Pitot tube anemometer: A structure that converts the differential pressure generated in the pitot tube into wind speed.In this explanation, we will use a vane anemometer as an example. I will explain.

The wind speed 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 speed 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 speed sensor 20 transmits new sensing 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 installed in a building to draw outside air into the building. The ventilation device 50 functions as an air supply or exhaust port. The ventilation device 50 is arranged to cover a ventilation hole formed through a wall of a building. Note that the vent may be formed in the ceiling or floor of the building. Operation of the ventilation device 50 controls the amount of air flow through the vent. The operation of the ventilation device 50 refers to opening and closing of the ventilation device 50 in conjunction with the operation of the louver 51, which will be described later.

The ventilation device 50 mainly includes a plurality of louvers 51 and an actuator 52.
The louver 51 has a wing-like shape. The plurality of louvers 51 are arranged side by side to cover the vent, thereby shielding the vent.
The louver 51 operates as the actuator 52 is driven. As each of the plurality of louvers 51 moves, a gap is formed between adjacent louvers 51. This causes the ventilation device 50 to be in an open position, creating a flow of air between the exterior and interior of the building through the vents. Note that 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 aspect of the operation of the louver 51 will be described later.

The actuator 52 is a drive device that operates the louver 51 based on a control signal transmitted 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 operation of the louver 51 as the motor is driven.

FIG. 2 is a schematic diagram showing the inside of a house 100 in which the ventilation system 1 is actually used. Note that 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 and 50B. The pair of ventilation devices 50A, 50B are provided on a pair of opposing walls, respectively. Therefore, the pair of ventilation devices 50A, 50B function as an air supply port and an air exhaust port. That is, by opening both of the pair of ventilation devices 50A and 50B, an air flow path is formed within the living room of the house 100 even if the window 40 is closed.

In the illustrated example, supply 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 flows 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 the formation of airflow within the living room.

Two wind speed sensors 20 are provided inside the house 100. Wind speed sensor 20 is placed on the ceiling of house 100. The wind speed sensors 20 are arranged 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 disposed within the living room of the house 100 between one and the other of the pair of ventilation devices 50 along the flow path Fc at intervals. Note that the location of the wind speed sensor 20 within the living room can be arbitrarily changed.

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

The ventilation device 50A is arranged to cover the ventilation hole K. A plurality of louvers 51 in the ventilation device 50A are arranged in the vertical direction so as to cover the ventilation hole K.
The actuator 52 is provided inside the wall near the louver 51.
Note that the shape and position of the louver 51 can be changed depending on the shape and position of the vent K.

FIG. 4 is a diagram (viewed from the Y direction arrow in FIG. 2) for explaining the opening/closing operation of the louver 51 in the ventilation device 50A. Note that in this figure, illustration of the actuator 52 is omitted. In addition, 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 wing-shaped members, are arranged such that those adjacent to each other in the vertical direction are located at different positions in the front-back direction. As the actuator 52 is driven, the louver 51 located on one side in the front-rear direction among the adjacent louvers 51 slides upward, thereby forming a gap between the louvers 51 . External air enters the living room through this gap as supply air As. The same applies when the ventilation device 50 functions as an exhaust port.

FIG. 5 is a diagram (viewed from the Y direction arrow in FIG. 2) for explaining another example of the opening/closing operation of the louver 51. Note that in this figure, illustration of the actuator 52 is omitted. In addition, 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. Then, as the actuator 52 is driven, each louver 51 rotates around its end (upper end), thereby forming a gap between the louvers 51. External air enters the living room through this gap as supply air As. The same applies when the ventilation device 50 functions as an exhaust port.
The opening/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 actuator 52 is 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. 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 or the like.

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 received from the outside (for example, various sensing data), and outputs the signals to the control module 190.

The input device 13 is a device for a user operating the control server 10 to input instructions. The input device 13 is realized, for example, by a remote controller 131 or the like to which an instruction is input by operating an input key. Note that the input device 13 may include other equipment such as a touch-sensitive device that inputs instructions by touching the operation surface.

The input device 13 converts an instruction input from a 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 reception port that receives electrical signals input from an external input device.

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

The storage unit 180 is realized by, for example, the memory 15, the storage 16, etc., and stores data and programs used by the control server 10. The storage unit 180 further stores a 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 in accordance with a model learning program based on learning data.

For example, the control model 181 is trained to output the opening degree (control amount) of the ventilation device 50 in response to input sensing data regarding wind speed. Here, the amount of operation of the louver 51 can be set based on the opening degree of the ventilation device 50.
At this time, the learning data 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 correct output data.

The control model 181 allows input of sensing data of a plurality of wind speeds. At this time, the control model 181 determines that all of the sensing data (i.e., the wind speed in the living room) acquired after this control from each of the plurality of wind speed sensors 20 is within a predetermined range as the opening degree of the ventilation device 50. Outputs the opening degree. Here, the term "within a predetermined range" preferably means, for example, a strength that is stronger than the minimum intensity at which a person in a living room can sense the wind and does not cause any trouble to a person in a living room.

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

The control model 181 according to this embodiment is, for example, a composite function with parameters that is a composite of 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 multilayer network model (hereinafter referred to as a multilayer network). The control model 181 using a multilayer 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 assumed to be used as a program module that is part of artificial intelligence software.

As the multilayer network according to this embodiment, for example, a deep neural network (DNN), which is a multilayer neural network that is a target of deep learning, can be used. As the DNN, for example, a convolutional neural network (CNN) that targets images may be used.
Further, the above is just 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 that uses the wind speed in the living room as a variable and is described by a function in which each variable is assigned a coefficient derived from past performance.

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

The reception module 191 performs processing for acquiring instructions input from the input device 13 or sensing data input from various sensors. Specifically, for example, the reception module 191 acquires an instruction input into the remote controller 131 from the user. Further, the reception module 191 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 amount of operation 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 regarding the wind speed to the control model 181. The control amount determination module 192 outputs the determined control amount 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.

Output module 194 outputs the control signal generated by signal generation module 193 to 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, the processing of the ventilation system 1 will be explained.
FIG. 7 is a flowchart showing an example of processing of the ventilation system 1.
In this description, the process is started with the ventilation device 50 open in response to an operation instruction inputted by 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 within the living room. Sensing of wind speed is repeatedly performed according to a preset measurement frequency. Therefore, subsequent processing is also repeatedly performed in accordance with the acquisition of new sensing data.

After step S101, the wind speed 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 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 determines the control amount from the opening degree of the ventilation device 50 output from the control model 181 by inputting sensing data regarding wind speed to 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. The opening degree of the ventilation device 50 is controlled by this control signal.

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 transmitted 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 actuator 52 of the ventilation device 50 is driven based on the control signal to operate the louver 51, thereby opening the ventilation device 50. This creates air supply and exhaust flow paths within the living room.
With the above steps, the processing of the system 1 ends.

Note that it is desirable that the ventilation device 50 be continuously controlled in response to changes in wind speed within the living room. That is, when the wind speed inside the living room temporarily increases, such as when a gust of wind from outside enters the living room, the ventilation device 50 is controlled to close. Further, when the wind speed in the living room becomes smaller than a predetermined range, the ventilation device 50 opens again and outside air enters the living room. By repeating this, the wind within the predetermined range of strength 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 control the ventilation device 50 always taking into consideration the strength of the wind inside the living room, and it is possible to maintain a comfortable flow of air within the living room.

Furthermore, ventilation can be smoothly performed in buildings where opening of windows is restricted, such as residences in tower apartments or rooms in high-rise hotels. Moreover, since an air flow is created in the living room simply by opening and closing the ventilation device 50, power consumption can be reduced compared to a general ventilation device or air conditioner.

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

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 falls within a predetermined range. In this case, the ventilation device 50 can be easily controlled by allowing local variations in wind strength such as in the vicinity of the ventilation device 50.

<4. Modified example>
Next, a system 2 according to a modified example will be explained. This modification differs from the previous embodiment in the part where the ventilation device 50 opens upon detecting the presence of a person in the living room.
In the following description, the same parts as in the embodiment described above are given the same reference numerals. 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. The human sensor 30 is a sensor that is provided in a living room and detects the presence of a person in the living room. The human sensor 30 may be configured to detect the presence of a person who has entered the flow path formed between the pair of ventilation devices 50. Further, a plurality of human sensors 30 may be arranged in the living room.

The human sensor 30 may be a sensor using various principles such as an infrared method, an electrostatic method, or an ultrasonic method as long as it can detect the presence of a person. In this description, a human sensor 30 using ultrasonic waves will be exemplified. The human sensor 30 detects changes in the propagation path by emitting ultrasonic waves, detecting changes in the propagation time by reflecting off the walls, floors, and ceilings of the living room, and detecting changes in the propagation path of the person who is an obstacle. Detect the presence within.
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 communicatively connected to 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. Note that the position where the human sensor 30 is arranged can be arbitrarily changed. 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 within the living room.
Furthermore, in the system 2, one wind speed sensor 20 is provided in the living room.

<4.2 System 2 processing>
Next, the processing of the ventilation system 2 will be explained.
FIG. 10 is a flowchart showing an example of processing of the ventilation system 2.
In this description, the process starts 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 sensor 30 senses the presence of a person by emitting ultrasonic waves into the living room and detecting changes in the time during which they are reflected and transmitted within 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 receiving 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 that controls the opening degree of the ventilation device 50 to open it. 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 transmitted 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 actuator 52 of the ventilation device 50 operates the louver 51 based on the control signal, so that the ventilation device 50 opens. This creates air supply and exhaust flow paths within the living room.
With the above, the unique processing of the system 2 is completed.
Thereafter, the above-described wind speed sensing process (step S101 in FIG. 7) by the wind speed sensor 20 is performed so as to respond to the air flow generated in the living room due to the opening of the ventilation device 50, and subsequent processes are performed. are performed repeatedly in sequence.

<4.3 Summary>
As described above, in the system 2 according to the modified example, when the human sensor 30 detects the presence of a person, the step of opening the ventilation device 50 is executed. Therefore, there is no need for a person in the room to open the ventilation device 50 according to an operational instruction, and convenience for the user 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 provided with comfortable air. can provide a flow of

Further, 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, similar to the process described above. In this case, when a person in the room leaves the room, there is no need to close the ventilation device 50 according to an operational instruction, which further improves convenience for the user.

<5. Other variations>
The system 1 may include various other sensors installed inside the living room or outside the building. Examples of the sensor 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 trained to output the optimal opening degree of the ventilation device 50 for each item value of the input sensing data.

Further, in the system 1, the opening degree of each of the pair of ventilation devices 50A and 50B may be made different from each other.
Thereby, the flow of air within the living room can be controlled more actively.

Additionally, the system 1 may vary the ease with which air flows depending on the area of the ventilation device 50.
Specifically, when the ventilation device 50 includes, for example, a plurality of louvers 51 arranged in a line in the vertical direction, the amount of operation thereof may be varied depending on the position of the louvers 51. As a result, for example, the size of the gap between adjacent louvers 51 is different between the upper half region and the lower half region of the ventilation device 50, so that air is The ease of flow will be different. Thereby, in comparison with a configuration in which the operating amount of the plurality of louvers 51 is set uniformly over the entire area of the ventilation device 50, a degree of freedom can be given to the flow of air generated in the living room.

Furthermore, in the case where the ventilation device 50 includes a plurality of louvers 51 arranged side by side in the vertical and horizontal directions, the louvers 51 may be operated only in a part of the area to locally circulate air. . For example, in one of the ventilation devices 50A disposed near the floor on the wall surface, only the plurality of louvers 51 occupying an area located on the lower left side when viewed from the living room are operated. Then, in the other ventilation device 50B disposed near the ceiling on the wall surface, only the plurality of louvers 51 occupying an area located above the left side when viewed from the living room are operated. As a result, air circulation is ensured at a position opposite to the living room, so that air can be exchanged efficiently throughout the living room.

Further, the system 1 may weight sensing data of the wind speed sensor 20 according to the position where the wind speed sensor 20 is placed. For example, among the plurality of wind speed sensors 20, sensing data from a wind speed sensor 20 located 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 relevant wind speed sensor 20, and The control amount of the ventilation device 50 may be determined based on the evaluation index regarding the wind speed. In this case, the control model 181 is trained to use the value of the evaluation index as input data and output the optimal opening degree of the ventilation device 50.

Further, 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 modification, 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 realizes the same functions.

Further, as shown in FIG. 13, in a system 4 according to a second example of another modification, 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 realizes the same functions. Furthermore, the sensing module 21 corresponds to a hardware resource equipped with a sensor unit that detects wind speed.
Furthermore, 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 of the control server 10 in FIG. 1.
