[motion]
Next, the operation of the airflow control system 1 will be described with reference to FIGS. 2 to 4.

FIG. 2 is a flowchart showing an example of the operation of the airflow control system 1 according to the embodiment.

First, the acquisition unit 11 acquires the existence information regarding the presence and absence of a person in the space and the attribute information of the person existing in the space (step S11). The existence information and the attribute information are information based on an image obtained by photographing the space with the camera 30. Specifically, the acquisition unit 11 acquires existence information and attribute information by analyzing an image captured in space by the camera 30 (that is, an image obtained by photographing) using existing image recognition or the like. To do. At this time, the acquisition unit 11 acquires the existence information and the attribute information by analyzing the image group obtained by repeatedly photographing the space with the camera 30 at regular intervals such as several seconds and several minutes. Further, the acquisition unit 11 acquires the attribute information by receiving the input by the user (facility manager, user, etc.) via the input device, for example. The existence information includes not only the presence and absence of a person in the space, but also information such as, for example, the number of existing people and the position of the person in the space. The attribute information includes information indicating whether the person existing in the space is a child or an adult (information indicating the age (age)). In addition, the attribute information may include gender, height, weight, hospital visit history, lifestyle, genetic information, and the like. For example, the acquisition unit 11 acquires the age (age), gender, height, weight, etc. of the attribute information by analyzing an image taken in space by the camera 30. Further, for example, the acquisition unit 11 acquires the hospital visit history, lifestyle, genetic information, and the like among the attribute information by inputting to the input device. Further, the acquisition unit 11 further acquires information indicating the number of times the door or window provided in the space is opened and closed by analyzing an image taken in the space by the camera 30.

Next, the determination unit 12 determines a target value of the concentration of the drug in the space based on the existence information and the attribute information (step S12). For example, when the existence information is information indicating that a person exists in the space, the determination unit 12 determines a target value of the concentration of the drug around the position where the person exists in the space. Further, for example, when the existence information is information indicating that no person exists in the space, the target value of the concentration of the drug in the entire space is determined. Here, a method of determining the target value by the determination unit 12 will be described.

FIG. 3 is a flowchart showing an example of the operation of determining the target value of the determination unit 12 according to the embodiment.

The determination unit 12 determines whether or not a person exists in the space (step S21). Specifically, the determination unit 12 makes the determination depending on whether or not the acquisition unit 11 has acquired information indicating that a person exists as existence information.

When the acquisition unit 11 acquires information indicating that a person exists in the space (Yes in step S21), the determination unit 12 sets the target value as information indicating that no person exists in the space. Determine a lower target value than when the is obtained. Specifically, the determination unit 12 determines a target value lower than the first threshold value (step S22). The first threshold value is a threshold value predetermined based on experience, experiment, theory, etc., and is a threshold value that causes less harm even if a person inhales a drug having a concentration lower than the first threshold value. In addition, less harm means, for example, less influence on a person's mind and body.

Next, the determination unit 12 determines whether or not the person existing in the space is a child (step S23). Specifically, the determination unit 12 makes the determination depending on whether or not the acquisition unit 11 has acquired the information indicating that the person existing in the space is a child as the attribute information. When there are a plurality of people in the space, it is determined whether or not the plurality of people include children.

When the acquisition unit 11 acquires information indicating that the person existing in the space is a child (Yes in step S23), the determination unit 12 determines that the person existing in the space is an adult as a target value. Determine a lower target value than when the information shown is obtained. Specifically, the determination unit 12 determines a target value lower than the second threshold value (step S24). The second threshold is a threshold lower than the first threshold. Further, the second threshold value is a threshold value predetermined based on experience, experiment, theory, etc., and is a threshold value such that even if a child inhales a drug having a concentration lower than the second threshold value, there is little harm. In step S24, for example, a target value lower than the target value determined in step S22 is determined.

When the acquisition unit 11 acquires information indicating that the person existing in the space is not a child (in other words, information indicating that the person is an adult) (No in step S23), the determination unit 12 sets the target value as a target value. Determine a higher target value than when acquiring information indicating that the person existing in the space is a child. Specifically, the determination unit 12 determines a target value that is equal to or higher than the second threshold value and lower than the first threshold value (step S25). In step S25, for example, the same target value as the target value determined in step S22 is determined.

On the other hand, when the acquisition unit 11 acquires information indicating that no person exists in the space (No in step S21), the determination unit 12 determines that a person exists in the space as a target value. Determine a higher target value than when the information shown is acquired. Specifically, the determination unit 12 determines a target value equal to or higher than the first threshold value (step S26).

Next, the determination unit 12 determines whether or not a person has existed in the space during a predetermined period (step S27). Specifically, the determination unit 12 makes the determination depending on whether or not the acquisition unit 11 has acquired information indicating that a person has existed in the space during a predetermined period as existence information. The predetermined period is, for example, a period from the present to a few minutes, a few hours, or the like.

When the acquisition unit 11 acquires information indicating that a person was present in the space during the predetermined period (Yes in step S27), the determination unit 12 sets the target value as a person in the space during the predetermined period. Determine a higher target value than when obtaining information indicating that it did not exist. Specifically, the determination unit 12 determines a target value equal to or higher than the third threshold value (step S28). The third threshold value is a threshold value higher than the first threshold value. Further, the third threshold value is a threshold value predetermined based on experience, experiment, theory, etc., and is a value that enables more effective cleaning or sterilization. In step S28, for example, a target value higher than the target value determined in step S26 is determined.

When the acquisition unit 11 acquires information indicating that no person was present in the space during the predetermined period (No in step S27), the determination unit 12 sets the target value as a person in the space during the predetermined period. Determine a lower target value than when obtaining information indicating that was present. Specifically, the determination unit 12 determines a target value that is equal to or higher than the first threshold value and lower than the third threshold value (step S29). In step S29, for example, the same target value as the target value determined in step S26 is determined.

In this way, the target value of the concentration of the drug in the space is determined.

Further, the target value of the concentration of the drug in the space may be determined according to the number of times the door or window provided in the space is opened and closed. The operation when the target value is determined according to the number of times the door or window provided in the space is opened and closed will be described with reference to FIG.

FIG. 4 is a flowchart showing another example of the operation of determining the target value of the determination unit 12 according to the embodiment. The processing in steps S31 to S33 is performed after the processing in steps S24, S25 and S28 is performed, for example.

First, the operation when the process in step S24 is performed will be described.

The determination unit 12 determines whether or not the number of times the door or window is opened and closed is equal to or less than a predetermined number of times (step S31). Specifically, the determination unit 12 makes the determination depending on whether or not the acquisition unit 11 has acquired information indicating that the number of times the door or window is opened / closed is equal to or less than a predetermined number of times. For example, the number of times the door or window is opened or closed when the process in step S24 is performed is the total number of times the door or window is opened or closed during the period when a person (child) is present in the space.

When the acquisition unit 11 acquires information indicating that the number of times the door or window is opened / closed is equal to or less than a predetermined number of times (Yes in step S31), the determination unit 12 sets the number of times of opening / closing a predetermined number of times as a target value. A lower target value is determined as compared with the case where the information indicating that the value is larger than is acquired (step S32).

When the acquisition unit 11 acquires information indicating that the number of times the door or window is opened / closed is greater than the predetermined number of times (No in step S31), the determination unit 12 sets the number of times of opening / closing a predetermined number of times as a target value. A higher target value is determined as compared with the case where the information indicating the following is acquired (step S33). For example, in step S33, a target value higher than the target value determined in step S24 is determined, and in step S32, the same target value as the target value determined in step S24 is determined. The target value determined in steps S32 and S33 is a target value lower than the second threshold value.

Further, the operation when the process in step S25 is performed will be described.

The determination unit 12 determines whether or not the number of times the door or window is opened and closed is equal to or less than a predetermined number of times (step S31). Specifically, the determination unit 12 makes the determination depending on whether or not the acquisition unit 11 has acquired information indicating that the number of times the door or window is opened / closed is equal to or less than a predetermined number of times. For example, the number of times the door or window is opened or closed when the process in step S25 is performed is the total number of times the door or window is opened or closed during the period when a person (adult) is present in the space. The predetermined number of times is a predetermined number of times based on experience, experiment, theory, and the like.

When the acquisition unit 11 acquires information indicating that the number of times the door or window is opened / closed is equal to or less than a predetermined number of times (Yes in step S31), the determination unit 12 sets the number of times of opening / closing a predetermined number of times as a target value. A lower target value is determined as compared with the case where the information indicating that the value is larger than is acquired (step S32).

When the acquisition unit 11 acquires information indicating that the number of times the door or window is opened / closed is greater than the predetermined number of times (No in step S31), the determination unit 12 sets the number of times of opening / closing a predetermined number of times as a target value. A higher target value is determined as compared with the case where the information indicating the following is acquired (step S33). For example, in step S33, a target value higher than the target value determined in step S25 is determined, and in step S32, the same target value as the target value determined in step S25 is determined. The target values determined in steps S32 and S33 are target values that are equal to or higher than the second threshold value and lower than the first threshold value.

Further, the operation when the process in step S28 is performed will be described.

The determination unit 12 determines whether or not the number of times the door or window is opened and closed is equal to or less than a predetermined number of times (step S31). Specifically, the determination unit 12 makes the determination depending on whether or not the acquisition unit 11 has acquired information indicating that the number of times the door or window is opened / closed is equal to or less than a predetermined number of times. For example, the number of times the door or window is opened or closed when the process in step S28 is performed is the total number of times the door or window is opened or closed during the period when a person is present in the space.

When the acquisition unit 11 acquires information indicating that the number of times the door or window is opened / closed is equal to or less than a predetermined number of times (Yes in step S31), the determination unit 12 sets the number of times of opening / closing a predetermined number of times as a target value. A lower target value is determined as compared with the case where the information indicating that the value is larger than is acquired (step S32).

When the acquisition unit 11 acquires information indicating that the number of times the door or window is opened / closed is greater than the predetermined number of times (No in step S31), the determination unit 12 sets the number of times of opening / closing a predetermined number of times as a target value. A higher target value is determined as compared with the case where the information indicating the following is acquired (step S33). For example, in step S33, a target value higher than the target value determined in step S28 is determined, and in step S32, the same target value as the target value determined in step S28 is determined. The target values determined in steps S32 and S33 are target values equal to or higher than the third threshold value.

In this way, the target value of the concentration of the drug in the space may be further determined according to the number of times the door or window provided in the space is opened and closed.

Then, the control unit 13 controls the air flow output from the blower 20 so that the concentration of the drug in the space becomes the target value determined by the determination unit 12 (step S13). Specifically, the control unit 13 controls at least one of the concentration of the drug contained in the airflow, the wind force of the airflow, and the wind direction of the airflow so that the concentration of the drug in the space becomes the target value. For example, information (for example, a table) in which the concentration of the chemical contained in the airflow, the wind force of the airflow, and the wind direction of the airflow are associated with each position in space and each target value is stored in the memory included in the airflow control device 10. The control unit 13 collates the target value determined by the determination unit 12 and the position of a person in the space acquired by the acquisition unit 11 with the information (for example, a table) to obtain the medicine contained in the air flow. Controls concentration, airflow wind, and airflow direction. By the control, the control unit 13 can set the concentration of the drug in the vicinity of the position where a person exists in the space or the entire space as a target value.

[Effects, etc.]
As described above, the airflow control system 1 according to the present embodiment is a system that cleans or sterilizes the space by controlling the airflow containing a substance having a cleaning function or a sterilizing function output from the blower 20. is there. The airflow control system 1 is based on the existence information regarding the presence and absence of a person in the space and the acquisition unit 11 that acquires the attribute information of the person existing in the space, and the existence information and the attribute information of the substance A determination unit 12 for determining a target value of the concentration and a control unit 13 for controlling the air flow so that the concentration becomes the target value are provided.

As a result, the target value of the concentration of the substance having a cleaning function or a bactericidal function in the space is determined based on not only the existence information regarding the presence and absence of a person in the space but also the attribute information of the person existing in the space. Therefore, the concentration of the substance in the space can be adjusted according to the attributes of the person existing in the space.

Further, when the acquisition unit 11 acquires the information indicating that the person exists, the determination unit 12 is lower than the case where the acquisition unit 11 acquires the information indicating that the person does not exist as the target value. The target value may be determined.

As a result, when a person is present in the space, the inside of the space can be cleaned or sterilized with the substance having a low concentration that has little effect on the mind and body of the person, and when there is no person in the space. The space can be effectively cleaned or sterilized by the substance at a high concentration.

Further, the attribute information is information indicating whether the person existing in the space is a child or an adult, and the determination unit 12 provides information indicating that the person existing in the space is a child by the acquisition unit 11. When acquired, a lower target value may be determined as the target value as compared with the case where the information indicating that the person existing in the space is an adult is acquired.

In general, children are more susceptible to the substance than adults, so when the person in the space is a child, the concentration of the substance in the space is higher than when the person in the space is an adult. It is preferable to lower the value. Therefore, when the person present in the space is a child, the space can be cleaned or sterilized by the substance having a lower concentration that has less influence on the mind and body of the person (child).

Further, when the acquisition unit 11 acquires information indicating that a person has existed in a predetermined period, the determination unit 12 indicates that the person did not exist in the predetermined period as a target value. A higher target value may be determined as compared with the case where the information is acquired.

For example, a person (especially a person infected with a virus or the like) can be a source of pollution. Therefore, a space that may be contaminated by the presence of a person can be cleaned or sterilized with a high concentration of the substance.

Further, the acquisition unit 11 further acquires information indicating the number of times of opening and closing of the door or window provided in the space, and the determination unit 12 indicates that the acquisition unit 11 indicates that the number of times of opening and closing is equal to or less than a predetermined number of times. When the information is acquired, a lower target value may be determined as the target value as compared with the case where the information indicating that the number of times of opening / closing is larger than a predetermined number of times is acquired.

For example, a door or window is a place where pollutants such as viruses can invade, and as the number of times of opening and closing increases, the space may become more contaminated. Therefore, a space in which doors or windows are frequently opened and closed can be cleaned or sterilized with a high concentration of the substance.

Further, the control unit 13 has at least one of the concentration of the substance contained in the airflow, the wind force of the airflow, and the wind direction of the airflow so that the concentration of the substance in the space becomes the target value determined by the determination unit 12. May be controlled.

Thereby, the concentration of the substance in the vicinity of the position where the person exists in the space or the entire space can be set to the target value.

Further, the existence information and the attribute information may be information based on an image obtained by photographing the space with the camera 30.

As a result, by analyzing the image obtained by the camera 30, it becomes easy to recognize the presence or absence of a person in the space and the state of the person, the door, and the window existing in the space.

(Other embodiments)
Although the airflow control system 1 according to the embodiment has been described above, the present invention is not limited to the above embodiment.

For example, in the above embodiment, the airflow control system 1 is provided with the camera 30, but a motion sensor or the like may be provided instead of the camera 30. Even in this case, the acquisition unit 11 can acquire information regarding the presence or absence of a person and the number of people.

The time during which the airflow containing the substance (drug, etc.) is output is not particularly limited, but for example, when there is no person in the space, the airflow containing the substance at a high concentration is output in a short time. , When a person is present in the space, the output of the airflow containing the substance at a low concentration may be performed for a long time.

Further, for example, in the above embodiment, the target value is determined based on the information on the presence and absence of a person in the space and the information on the age (age) of the person as the existence information and the attribute information. Not limited to. For example, the target value may be determined based on the number of people existing in the space, the gender, height, weight, hospital visit history, lifestyle, genetic information, etc. of the people existing in the space. For example, a high target value may be determined when the number of people existing in the space is large, the height is high, the weight is heavy, or there is a history of hospital visits such as a cold.

Further, for example, the determination unit 12 may determine the target value based on the epidemiological model in addition to the existence information and the attribute information. The epidemiological model can accurately estimate the distribution of pollution levels in space (risk of pollution by pollutants, discomfort, etc.). For example, target values in highly polluted areas in space can be set in other areas. Can be determined to be higher than.

Further, for example, the determination unit 12 may determine the target value based on the genomic information (microbiota information) of the pollutant existing in the space in addition to the existence information and the attribute information. Since the type of pollutant existing in the space can be known from the genomic information, for example, when the type of pollutant is a high-risk virus or the like, the target value can be determined to be a higher value.

Further, for example, the determination unit 12 may determine the target value based on the operation of other blowers existing in the space in addition to the existence information and the attribute information. Since the concentration of a substance (drug, etc.) in the space can change immediately depending on the airflow output by another blower, the target value can be set to a higher value or a lower value in advance so that the concentration may change immediately. ..

Further, for example, the airflow control device 10 (airflow control system 1) shown in the above embodiment may share a part of the functions with an external device (for example, a server or the like) capable of communicating with the airflow control device 10. However, the airflow control device 10 (airflow control system 1) may be an external device.

Further, the present invention can be realized not only as an airflow control system but also as a method including steps (processes) performed by each component constituting the airflow control system.

Specifically, the airflow control method is a method of cleaning or sterilizing the space by controlling the airflow containing a substance having a cleaning function or a sterilizing function output from the blower 20. The airflow control method is based on the acquisition step of acquiring the existence information regarding the presence and absence of a person in the space and the attribute information of the person existing in the space, and the existence information and the attribute information, and the concentration of the substance in the space. It includes a determination step of determining a target value and a control step of controlling the air flow so that the concentration reaches the target value.

This makes it possible to provide an airflow control method capable of adjusting the concentration of the substance in the space to a concentration according to the attribute of a person existing in the space.

For example, those steps may be performed by a computer (computer system). Then, the present invention can be realized as a program for causing a computer to execute the steps included in those methods. Further, the present invention can be realized as a non-temporary computer-readable recording medium such as a CD-ROM on which the program is recorded.

For example, when the present invention is realized by a program (software), each step is executed by executing the program using hardware resources such as a computer CPU, memory, and input / output circuits. .. That is, each step is executed when the CPU acquires data from the memory or the input / output circuit or the like and performs an operation, or outputs the calculation result to the memory or the input / output circuit or the like.

Further, each component included in the airflow control system of the above embodiment may be realized as a dedicated or general-purpose circuit.

Further, each component included in the airflow control system of the above embodiment may be realized as an LSI (Large Scale Integration) which is an integrated circuit (IC: Integrated Circuit).

Further, the integrated circuit is not limited to the LSI, and may be realized by a dedicated circuit or a general-purpose processor. A programmable FPGA (Field Programmable Gate Array) or a reconfigurable processor in which the connection and settings of circuit cells inside the LSI can be reconfigured may be utilized.

Furthermore, if an integrated circuit technology that replaces an LSI appears due to advances in semiconductor technology or another technology derived from it, it is natural that the technology will be used to create an integrated circuit for each component included in the airflow control system. May be good.
