(Embodiment 1)
Hereinafter, a contamination amount estimation system 10 according to an embodiment of the present invention will be described.

(Constitution)
FIG. 1 is a schematic configuration diagram showing a contamination amount estimation system 10 according to the present embodiment.

The contamination amount estimation system 10 is a contamination amount estimation method for estimating the amount of contamination in each region (at least one region) indoors in a facility (house, office, store, hospital, factory, etc.), that is, inside a building (building, etc.). The system to execute. In other words, the contamination amount estimation system 10 estimates the degree of contamination by air pollutants in the air in an indoor area, and outputs an estimation result. Here, an indoor area | region is spatial areas, such as a room, a hallway, and a front door, for example. Pollutants are harmful substances (heavy metals, asbestos, etc.), dust, pathogens (viruses, bacteria, etc.), pollen, PM2.5, mold, aromatic compounds and other various particles (powder, molecules, atoms, etc.) , Particulate matter, etc.). Here, description will be made using an example in which pathogens (microorganisms such as bacteria, viruses, etc.) are mainly assumed as pollutants.

As shown in FIG. 1, the contamination amount estimation system 10 includes a sensor 101 installed in a region 11 in a facility and a contamination amount estimation device 100.

The region 11 is a spatial region that is a target of estimation of the contamination amount by the contamination amount estimation device 100. The region 11 may be the entire facility or a part thereof.

The sensor 101 is a sensor used for detecting the number of people located in the area 11, and is, for example, an image sensor (camera), a radar, or the like. For example, the number of people located in the area 11 is detected by analyzing an image captured in the area 11 by the image sensor (that is, an image generated by the imaging) using an existing human recognition technique or the like. It becomes possible.

The contamination amount estimation apparatus 100 is a computer including a processor (microprocessor), a memory, a communication interface (communication circuit, etc.), a user interface, and the like. The user interface includes, for example, a display such as an LCD (Liquid Crystal Display) and an input device such as a keyboard and a touch panel. The memory is ROM, RAM, or the like, and may include, for example, a nonvolatile memory. The processor performs processing for controlling a communication interface, a display, and the like by executing a program stored in the memory. The memory stores a program for causing the processor to execute the process. The contamination amount estimation device 100 may include a hard disk device or the like.

As shown in FIG. 1, the contamination amount estimation apparatus 100 including the hardware configuration described above includes a storage unit 110, an acquisition unit 120, and a functional block (components in terms of functions) for performing contamination amount estimation. An estimation unit 130 and an output unit 140 are provided. Hereinafter, each of these components will be described.

The storage unit 110 is realized by a storage medium such as a memory or a hard disk, and stores relationship information 22 indicating the relationship between the characteristics of the indoor area and the amount of contamination in the area due to contaminants (for example, pathogens). The relationship information 22 is information determined in advance on the basis of experience, experiment, theory, etc. regarding the relationship between the characteristics of indoor areas and the amount of contamination, and is information expressed in a table, mathematical formula, or any other form. There may be. FIG. 2 shows an example of the relationship information 22. It is useful to include, as the relationship information 22, user relationship information indicating a relationship between characteristics regarding the use of an indoor area by a person (for example, characteristics regarding how the area is used by a person) and the amount of contamination. The relationship information A and the relationship information B shown in FIG. 2 are examples of user relationship information. In the example of FIG. 2, the contamination amount is represented by a contamination level that takes a level (value) from 0 to 10, with 0 indicating no contamination and 10 indicating the maximum degree of contamination.

The relationship information A in FIG. 2 indicates the relationship between the area application (that is, the purpose of use by people in the indoor area) and the contamination level. In the example of the figure, for example, the contamination level is 5 when the indoor area is a waiting room of a hospital, the contamination level is 3 when it is an office, and the contamination level is when it is a toilet. 8.

Further, the relationship information B in FIG. 2 indicates the relationship between the area user density and the contamination level. The area user density is, for example, the density of people staying in an indoor area per unit time (for example, 1 hour) (a value obtained by dividing the number of people staying in the area by the area of the area or the volume of the area). . The example of FIG. 2 is an example in which the area user density is a value obtained by dividing the number of people staying in an indoor area per hour by the area (square m) of the area. In this example, for example, when the area user density (person / square m) is less than 0.5, the contamination level is 1, and the area user density (person / square m) is 0.5 or more and 1.0. If the area density is less than 1.5, the contamination level is 2, and if the area user density (person / square m) is 1.0 or more and less than 1.5, the contamination level is 4. For example, in view of the fact that pathogens (bacteria, viruses, etc.) as pollutants can infect and propagate from person to person, related information B indicates that the contamination level is high when the area user density is high. It is defined to show the relationship of the tendency to increase.

In FIG. 2, the relationship information A and B is illustrated, but various other relationship information (user relationship information or other relationship information) may be defined and stored as the relationship information 22 in the storage unit 110. it can. Examples of user-related information include information indicating the relationship between the level of contamination and the level of the person using the indoor area and whether it is an adult or a child, the body temperature of the person using the indoor area, the calorific value, etc. And information indicating the relationship between the contamination level and the contamination level. In addition, as other related information, information indicating the relationship between the degree of dust rising in an indoor area and the contamination level, physical properties of the floor of an indoor area, the surface of a desk or the like installed in the area ( For example, information indicating the relationship between the contamination level and the presence of antibacterial effect, the degree of retention of contaminants, and the like.

The acquisition unit 120 is realized by an input device as a user interface, a processor that executes a program, and the like, and acquires input information 21 including characteristics of an indoor area. FIG. 3 shows an example of the input information 21 acquired by the acquisition unit 120. The input information 21 in the figure shows the characteristics of the area, such as the area usage, the area user number, the area floor area, and the like. In the example of FIG. 3, the input information 21 indicates that the area use (use of the indoor area 11) is a waiting room in a hospital, the area use number (number of people staying in the area 11) is 12, and the area floor area Is 20 square meters. It is useful for the estimation of the amount of contamination in the area that the input information 21 includes user characteristics related to the use of the area by a person, such as the area usage and the number of people using the area. The number of people using the area is an example of a characteristic related to the number of people who use the area, but any manner of expressing the characteristic related to the number of people using the area may be used. For example, the number of people staying per unit time, the number of people and the staying time per person, the statistical processing results (maximum number of people, median, etc.) of the number of staying people over multiple unit times, etc. It may be. Each characteristic of the area acquired by the acquisition unit 120 as the input information 21 is not limited to the above-described area use, the number of area users, and the area floor area, and may include any characteristic corresponding to the above-described relation information. In addition, the acquisition unit 120 may not be able to acquire all the characteristics of the area such as the area usage, the number of people using the area, the area floor area, and the like. Then, the amount of contamination in the area will be estimated.

The acquisition unit 120 uses some of the characteristics of the input information 21 (for example, area usage, area floor area, etc. in the example of FIG. 3) via the input device as a user interface (facility manager, worker, usage). Obtained by receiving an input from the user. Further, the acquisition unit 120 acquires some characteristics (for example, the number of people using the area in the example of FIG. 3) in the input information 21 by sensing with the sensor 101 in the indoor area 11 that is a target for estimating the amount of contamination. . Specifically, for example, an image sensor is used as the sensor 101, and the acquisition unit 120 analyzes an image group obtained by repeatedly imaging the area 11 every predetermined period such as several minutes or several hours with the image sensor, and analyzes the area. By detecting the number of persons in the area 11, the number of people using the area is acquired.

The estimation unit 130 is realized by a processor or the like that executes a program. Based on the input information 21 acquired by the acquisition unit 120 and the relationship information 22 stored in the storage unit 110, the estimation unit 130 is a target region (here, the region 11). ). The estimation of the contamination amount by the estimation unit 130 is realized by, for example, identifying the contamination level according to the input information 21 by referring to the relationship information 22 and writing the contamination level in a storage medium such as a memory or a hard disk. The The result of estimation by the estimation unit 130 is used by the output unit 140.

As a specific example, the estimation unit 130 determines the contamination level from the relationship information 22 (specifically, the relationship information A related to the region usage) according to the region usage which is one characteristic in the input information 21 acquired by the acquisition unit 120. Is identified. According to the example of FIGS. 2 and 3, the contamination level is specified as 5. In addition, the contamination level is identified from the relationship information 22 (specifically, the relationship information B related to the area user density) according to the area use number and the area floor area as characteristics in the input information 21 acquired by the acquisition unit 120. To do. According to the example of FIGS. 2 and 3, the density (person / square m) of the person calculated from the input information 21 is 0.6, so the contamination level is specified as 2. For example, when the contamination level is specified based on a plurality of pieces of relation information, the estimation unit 130 multiplies or adds a predetermined calculation F (eg, multiplies or adds each contamination level) based on each contamination level specified by all the pieces of relation information. The total contamination level is specified by a calculation to be performed). For example, depending on the multiplication of one contamination level in the range from 0 to 10 specified based on certain relationship information to one contamination level in the range from 0 to 10 specified based on another relationship information, , One contamination level ranging from 0 to 100 can be specified. Note that the contamination level in each relational information may be normalized so as to be expressed in the range of 0 to 1. The predetermined calculation F may be an operation for averaging the contamination levels specified corresponding to the respective pieces of related information. In addition, a calculation for obtaining a weighted average of each contamination level specified based on each relationship information and defining a weight corresponding to each relationship information may be a predetermined calculation F, or specified based on each relationship information The calculation for obtaining the maximum value of each contamination level may be the predetermined calculation F.

The estimation unit 130 performs the predetermined calculation F based on each contamination level specified by each related information, so that as the information amount of the input information 21 acquired by the acquisition unit 120 is larger, the estimation of the contamination level is generally performed. Estimation with high accuracy is possible. When the total contamination level is specified, the total contamination level is used for the output unit 140.

Note that the estimation unit 130 may use any calculation to identify the contamination level based on the relationship information 22 according to the input information 21. For example, the estimation unit 130 identifies the contamination level as 5 from the relationship information A in FIG. 2 according to the area usage of the input information 21 in FIG. The total contamination level may be specified by multiplying the human density calculated from the area. Further, the estimation unit 130 may represent the contamination amount in a format other than the contamination level, for example, the contamination amount may be represented by a BSA (bovine serum albumin) concentration.

The output unit 140 is realized by a user interface such as a display, a processor that executes a program, and the like, and outputs the contamination amount information indicating the contamination amount (for example, the contamination level) estimated by the estimation unit 130. For example, the output of the contamination amount information by the output unit 140 is performed by presentation to the user (for example, display on a display). The output unit 140 may output the contamination amount information including information on prevention or countermeasure of the contamination according to the estimated contamination amount (contamination level or the like). For example, the output unit 140 shows a correspondence relationship between the amount of contamination and the concentration of a drug (for example, hypochlorous acid) to be sprayed in the region for reducing the contaminant (for example, inactivating the pathogen). Based on the information, the concentration of the medicine may be calculated from the contamination amount, and the concentration information may be included in the contamination amount information and output.

In addition, the contamination amount estimation apparatus 100 uses the acquisition unit 120 as a part of the input information 21 based on the number of people using the area (the number of people staying in the unit 11 in the unit time) by sensing with the sensor 101 installed in the indoor area 11. Obtain (see FIG. 3).

Subsequently, the contamination amount estimation apparatus 100 estimates the contamination amount (for example, contamination level) for the region 11 based on the input information 21 and the relationship information 22 by the estimation unit 130 (step S12). For example, the estimation unit 130 specifies a contamination level corresponding to each of the relationship information A and the relationship information B (see FIG. 2) described above, and then performs a predetermined calculation F that reflects each contamination level in the result. Is specified (estimated).

Next, the contamination amount estimation device 100 outputs contamination amount information indicating the contamination amount (for example, the overall contamination level specified by the estimation unit 130) (step S13). In step S13, for example, the contamination amount information can be displayed on a display or the like.

Thereby, the user can know the amount of contamination in the region 11 that is the estimation target of the contamination amount by visually checking the contamination amount information. The contamination amount estimation apparatus 100 may include, for example, information such as the concentration of a medicine to be sprayed on the region 11 in order to reduce the contaminants in the contamination amount information. By confirming, it becomes possible to spray an appropriate drug. In addition, since the contamination amount estimation system 10 estimates the contamination amount without using a contamination detection sensor (such as an air quality sensor), the estimation result of the contamination amount is also used for preventing future contamination. it can.

The amount of contamination (here, the region 11a) is estimated. The estimation unit 130a identifies one or more contamination levels according to the input information 21 by referring to the relationship information 22 in the same manner as the estimation unit 130 described in the first embodiment, for example. Furthermore, the estimation unit 130a performs a predetermined calculation F that adds or multiplies a larger numerical value as the influenza epidemic level represented by the epidemic information 23 is higher than the result of multiplying or adding the identified contamination levels. The correct contamination level. The estimation by the estimation unit 130a is realized by specifying the total contamination level and writing the total contamination level in a storage medium such as a memory or a hard disk.

That is, the acquisition unit 120 or the like receives information indicating the power usage corresponding to the area 11 or the like, and the user of the area 11 or the like is based on an estimation criterion or the like determined that the power usage increases as the number of people increases. By estimating the number of people, the number of people using the area may be acquired.

Moreover, although the said embodiment demonstrated the example which estimates the amount of pollution targeting one area | region 11 (or area | region 11a) in a facility, the object of estimation of the amount of pollution by the pollution amount estimation apparatuses 100 and 100a is considered. A plurality of areas may exist in a certain facility. Further, one or a plurality of regions for which the amount of contamination is to be estimated may exist in each of a plurality of facilities. Note that the contamination amount estimation apparatus 100 may be located in a region that is an estimation target of the contamination amount.

In the above embodiment, the acquisition unit 120a has acquired an example in which the acquisition unit 120a acquires the epidemic information 23 related to the epidemic level of a disease (influenza) caused by a pathogen as a pollutant. However, in view of the tendency of the influenza epidemic level to increase in the winter according to the estimation time (season) of the contamination amount without using the server 30, the contamination amount estimation device 100a determines the epidemic level of the disease caused by the pathogen. The fashion information 23 may be generated by estimation. In addition, the contamination amount estimation devices 100 and 100a store relationship information indicating the relationship between the season and the contamination amount (contamination level, etc.), and estimate the contamination amount according to the estimation time (season) of the contamination amount. Also good.

Moreover, the contamination amount estimation apparatuses 100 and 100a shown in the above embodiment may share a part of functions with an external device (for example, the server 30) that can communicate with the contamination amount estimation apparatuses 100 and 100a.

Further, the execution order of the processing procedures (the procedures shown in FIGS. 4 and 7) in the contamination

amount estimation systems

10 and 10a described above is not necessarily limited to the order described above, and deviates from the gist of the invention. The execution order can be changed or a part of the execution order can be omitted as long as it is not. Further, all or part of the processing procedure (the procedure shown in FIGS. 4 and 7 and the like) may be realized by hardware or may be realized by using software. For example, the contamination amount estimation apparatuses 100 and 100a may be configured only by hardware that does not include software (program). Moreover, the contamination amount estimation apparatuses 100 and 100a may record a program executed by a processor on a recording medium and distribute or distribute the program. For example, by installing the distributed program in a computer and causing the processor to execute the program, it is possible to cause the computer to perform all or part of the processing procedures illustrated in FIGS. 4 and 7.

Further, embodiments realized by arbitrarily combining the constituent elements and functions shown in the above-described embodiment, modification, etc. are also included in the scope of the present invention.

The comprehensive or specific various aspects of the present invention include one or a plurality of combinations such as an apparatus, a system, a method, an integrated circuit, a computer program, and a computer-readable recording medium.

Hereinafter, the configuration, deformation mode, effects, and the like of the contamination amount estimation system, the contamination amount estimation method, and the program according to one aspect of the present invention will be described.

(1) A contamination amount estimation system according to an aspect of the present invention includes a storage unit (for example, storage unit 110) that stores relationship information indicating a relationship between characteristics of an indoor region and the amount of contamination of the region due to a contaminant. Based on the acquisition unit (for example, the

acquisition unit

120, 120a) that acquires input information including characteristics of an indoor region (for example, the

region

11, 11a), the input information acquired by the acquisition unit, and the relationship information An estimation unit (e.g.,

estimation units

130 and 130a) that estimates the amount of contamination in the region. The relationship information can be defined based on experience, experiment, theory, and the like. This makes it possible to appropriately estimate the amount of contamination in an indoor area used by a person. In addition, the estimation of the amount of contamination in this contamination amount estimation system does not require a sensor for detecting contamination (such as an air quality sensor). The amount of contamination can be estimated predictively prior to beginning. As described above, the contamination amount estimation system can cope with the case where the contamination detection sensor cannot detect, and the estimation result by the contamination amount estimation system is also used for the prevention of contamination in the area where the contamination amount is estimated. Be available.

(2) For example, the contamination amount estimation system may include an output unit (for example, the output units 140 and 140a) that outputs the contamination amount information indicating the contamination amount estimated by the estimation unit (for example, the

estimation units

130 and 130a). Good. Thereby, the administrator, user, etc. of the area | region used as the estimation object of pollution amount can confirm the estimated pollution amount.

(3) For example, the relationship information stored in the storage unit includes user relationship information indicating the relationship between the characteristics related to the use of the indoor area by the person and the amount of contamination, and the input information acquired by the acquisition unit is determined by the person. It is good also as including the user characteristic regarding utilization of one field (for

example field

11, 11a). In this way, by defining the relationship information based on the correlation between the amount of contamination in the indoor area and the characteristics related to use by the person in the area (for example, the number of people staying in the area, the usage of the area, etc.) Therefore, it is possible to appropriately estimate the amount of contamination for one area used by a person.

(4) For example, the above-described user relationship information indicates the relationship between the usage of the indoor area and the amount of contamination, and the above-described user characteristic may indicate the usage of one region that is the estimation target of the contamination amount. Good. As a result, the amount of contamination can be appropriately estimated according to the use of one area that is the target of estimation of the amount of contamination.

(5) For example, the above-mentioned user relationship information indicates the relationship between the characteristic regarding the number of people staying in an indoor area and the amount of contamination, and the above-mentioned user characteristic is in one area that is the target of estimation of the contamination amount. It is good also as including the characteristic regarding the number of people who stay. As a result, the amount of contamination can be estimated appropriately based on the fact that the number of users in one area to be estimated for the amount of contamination increases as the number of contaminants such as infectious viruses increases.

(6) For example, the pollutant that causes the contamination related to the contamination amount estimated by the contamination amount estimation system may be a pathogen. As a result, the amount of contamination in one area (for example, the

areas

11 and 11a) due to the pollutant that infects people from person to person is appropriately estimated based on the characteristics related to the use of the person in that area.

(7) For example, the acquisition unit (for example, the acquisition unit 120a) further acquires epidemic information related to the epidemic level of the pathogen (that is, the epidemic level of the disease caused by the pathogen), and the estimation unit (for example, the estimation unit 130a) acquires It is good also as estimating the pollution amount of 1 area | region based also on the fashion information acquired by the part. As a result, for example, the amount of contamination in one area due to influenza virus or the like can be appropriately estimated based on the level of influenza epidemic in the location area of one area.

(8) For example, the acquisition unit may acquire at least one characteristic in the above-described input information by sensing a region that is a target for estimating the amount of contamination with a sensor. As a result, for example, the number of users in one area, which dynamically changes with the passage of time, can be obtained relatively easily (for example, without requiring sequential user input). Based on the result, it becomes possible to appropriately estimate the amount of contamination in the one area.

(9) For example, the acquisition unit receives at least one characteristic in the above-described input information from a device (for example, a computer constituting an arbitrary system such as an accounting system) in one area that is an estimation target of the contamination amount. It is good also as acquiring by. This can reduce the labor and burden of manually inputting the characteristics of the input information.

(10) For example, the acquisition unit acquires at least one characteristic in the above-described input information by receiving an input by a user (for example, an administrator or a user of the contamination amount estimation target area) via the user interface. It is good to do. As a result, it is possible to appropriately estimate the contamination amount by utilizing information that the user knows about the contamination amount estimation target region.

(11) For example, the contamination amount estimation system estimates a device (for example, the contamination countermeasure device 102) having a contamination countermeasure function installed in one area that is a target of contamination amount estimation by the estimation unit (for example, the estimation unit 130a). It is also possible to transmit a control signal corresponding to the contamination amount. For example, the control unit 141 transmits this control signal. Thereby, the pollution control equipment 102 etc. can be controlled based on the estimated pollution amount. For this reason, it becomes possible to prevent or deal with contamination according to the amount of contamination.

(12) The contamination amount estimation method according to an aspect of the present invention includes an acquisition step (for example, steps S11 and S21) for acquiring input information including characteristics of an indoor region (for example, the

regions

11 and 11a), and an acquisition step. Estimation based on the input information acquired in step 1 and the predetermined relationship information indicating the relationship between the characteristics of the indoor area and the amount of contamination of the area due to the pollutant. Steps (for example, steps S12 and S23). This makes it possible to appropriately estimate the amount of contamination in an indoor area used by a person.

(13) A program according to an aspect of the present invention is a program for causing a device including a processor (microprocessor) to perform a contamination amount estimation process, and the contamination amount estimation process has characteristics of an indoor area. The acquisition step (for example, steps S11 and S21) for acquiring the input information including the relationship between the input information acquired in the acquisition step and the predetermined characteristics of the indoor area and the amount of contamination of the area due to the pollutant And an estimation step (e.g., steps S12 and S23) for estimating the contamination amount of the one region based on the relationship information indicating By installing this program in an apparatus including a processor and causing the processor to execute the program, it is possible to appropriately estimate the amount of contamination in an indoor area used by a person.
