[0026] The environmental information processing system, terminal device, and program according to the present embodiment will be described in detail below with reference to the accompanying drawings, showing preferred embodiments. Note that the present embodiment is not limited to these embodiments, and includes various modifications or improvements. In other words, the components described below include those that a person skilled in the art can easily imagine, and those that are substantially the same, and the components described below can be combined as appropriate. Furthermore, in the present embodiment, various omissions, substitutions, or modifications of the components can be made without departing from the gist of the present invention.

[0027] [overview] In recent years, the concept of "living environment disease" which is a disease caused by the living environment (indoor environment) has been proposed. Examples of living environment disease include circulatory diseases such as high blood pressure, heat shock, and heat stroke caused by temperature and humidity. Therefore, a technology for measuring the indoor environment of a building is required. By measuring the indoor environment of a building, for example, it is possible to evaluate the value of a newly built or renovated building, and to determine the need for renovation of an existing building (such as a house, a hospital, or an elderly care facility). In addition, based on the measured indoor environment, it is possible to make proposals to improve the living environment, such as installing or replacing air conditioning equipment and renovating the insulation of a building. However, according to conventional measurement techniques, it may take a huge amount of energy and effort to measure the indoor environment of a building, or the system for measurement may be complicated. According to an environmental information processing system described later, it is possible to measure and evaluate the indoor environment with low energy and simply based on at least three environmental information acquisition devices installed in the building.

[0028] The environmental information acquisition device is a device that acquires at least two kinds of environmental information. The environmental information is information that changes with time and indicates values ​​of indices related to the indoor environment. The indices related to the indoor environment include, for example, indices that tend to be factors that make people feel comfortable, such as temperature, humidity, sound, illuminance, and airflow, indices that tend to affect people's health (physical condition), such as volatile organic compounds concentration, cleanliness, and air pressure, and indices that serve as a guide for whether ventilation is being performed appropriately, such as carbon dioxide concentration. Here, the cleanliness is an index that indicates the degree of pollutants contained in a certain volume. The cleanliness may be indicated, for example, by the mass, ratio (concentration), dimensions, and quantity of pollutants such as dust, dirt, and airborne microorganisms that are suspended particles in the room. The environmental information acquisition device may be composed of a plurality of devices. For example, the environmental information acquisition device may be configured by a device that acquires certain environmental information (first environmental information), a device that acquires environmental information (second environmental information) whose type of index is different from that of the first environmental information, and a device that transmits the acquired environmental information.

[0029] In the above, it has been explained that the carbon dioxide concentration is an index that serves as a guide for whether ventilation is being performed appropriately. However, for example, a high carbon dioxide concentration of 1500 [ppm] or more may cause drowsiness, and the carbon dioxide concentration may also be an index that is likely to affect health. In this manner, in this embodiment, one type of environmental information may serve as an index for each of a plurality of indices (for example, health and ventilation) that are evaluated differently.

[0030] [Present embodiment] First, an example of the installation position of an environmental information acquisition device installed in a building will be described with reference to Figs. 1 and 2.

[0031] FIG. 1 is a floor plan of a building for explaining the installation position of an environmental information acquisition device. The building (house) shown in FIG. 1 has a first bedroom BER1, a second bedroom BER2, a living room LR, a toilet WC, a washroom DR, a bathroom BAR, a closet CL, a corridor C connecting these rooms, and an entrance E. The first device 1, the second device 2, and the third device 3 shown in FIG. 1 are environmental information acquisition devices installed in the house. When measuring the indoor environment of the building, two environmental information acquisition devices are installed in a specific room (first room), and one is installed in a room (second room) of a different type from the first room. Note that the different types of rooms refer to rooms with different uses or sizes, for example. FIG. 1 shows an example in which two environmental information acquisition devices (first device 1, second device 2) are installed in the first bedroom BER1 and one (third device 3) is installed in the corridor C. That is, two environmental information acquisition devices are installed in a room where a person stays for a long time, and one is installed in a room where a person stays for a short time or passes through without staying. By installing more environmental information acquisition devices in rooms where people stay for a longer time, the indoor environment of the room where people stay for a longer time can be measured more accurately.

[0032] FIG. 1 shows an example in which a combination of a first room (first bedroom BER1) and a second room (corridor C) is a living room and a non-living room. Here, a living room is a room that is continuously used for purposes such as living, working, and entertainment. Examples of living rooms include a living room, a bedroom, and a kitchen. A non-living room is a room that is not a living room, that is, a room that is not continuously used for purposes such as living, working, and entertainment. Examples of non-living rooms include an entrance E, a toilet WC, a corridor C, a bathroom BAR, a washroom DR, a closet CL, a storeroom, and the like. In general, people in a building often move between living rooms and non-living rooms. When the indoor environments of living rooms and non-living rooms are different (for example, the difference in the amount of dust, temperature, etc. is large), moving between rooms with different indoor environments may be harmful to the health of the person moving between them. Therefore, the environmental information processing system 10 described below can measure the indoor environments of the two rooms by installing environmental information acquisition devices in a living room (first bedroom BER1) and a non-living room (corridor C), and evaluate whether the indoor environments diverge.

[0033] In FIG. 1, the first room in which two environmental information acquisition devices are installed and the second room in which one environmental information acquisition device is installed are shown as an example in which it is not necessary to go through other rooms when moving between the rooms, such as the first bedroom BER1 and the corridor C (they are adjacent to each other through a door). However, this embodiment is not limited to this example. The first room and the second room may be a combination of rooms in which it is necessary to go through other rooms when moving between the first room and the second room. The first room and the second room may be a combination in which one room is passed through to move between the two rooms, such as the first bedroom BER1 and the living room LR, the living room LR and the toilet WC, etc. In addition, the first room and the second room may be a combination in which multiple rooms are passed through to move between the two rooms, such as the first bedroom BER1 and the bathroom BAR, the living room LR and the bathroom BAR, etc.

[0034] FIG. 2 is a perspective view of a room for explaining the installation positions of the environmental information acquisition devices. With reference to the same figure, an example of the positions of the environmental information acquisition devices (first device 1, second device 2, third device 3) installed in the house shown in FIG. 1 will be explained. FIG. 2 shows a part of the first bedroom BER1 and the corridor C shown in FIG. 1. The first device 1 is installed in the first bedroom BER1 at a first position, which is a position of a first height L1 (for example, 0.1 [m]) from the floor of the first bedroom BER1. The second device 2 is installed in the first bedroom BER1 at a second position, which is a position of a second height L2 (for example, 1.1 [m]) from the floor of the first bedroom BER1. The third device 3 is installed in the corridor C at a third position, which is a position of a third height L3 from the floor of the corridor C. Here, the floor is a horizontal, flat, plate-like structure located on the lower surface of each floor of the internal space (room) of a building. In addition, when the floor position serving as the reference for height cannot be determined due to a step or a slope on the floor, the position (height) at which the environmental information acquisition device is installed may be based on, for example, the place in the room where a person stays the longest (for example, the floor where bedding is placed in a bedroom). The first device 1 is installed so that the center of the first device 1 is at a position of a first height L1 from the floor. The center of the first device 1 may be, for example, the position of the center of gravity of the first device 1, or may be a position where the height from the bottom of the first device 1 is half the total height of the first device 1. The same applies to the second device 2 and the third device 3. Hereinafter, an example in which the first height L1 is lower than the second height L2 will be described. That is, a case in which the first device 1 is installed at a position closer to the floor than the second device 2 will be described.

[0035] According to ISO 7726 "Ergonomics of the thermal environment - Instruments for measuring physical quantities" published in 1998, when measuring and evaluating the thermal environment, the recommended measurement heights are 1.1 m (for a standing human body) and 0.6 m (for a seated human body), which correspond to the height of the abdomen. When evaluating the distribution characteristics (the nature and state of distribution), it is recommended to measure 0.1 m and 1.7 m (for a standing human body) and 0.1 m and 1.1 m (for a seated human body), which correspond to the heights of the ankles and head. Based on these heights, the first height L1, the second height L2, and the third height L3 may be determined.

[0036] The first device 1 and the second device 2 installed in the first room may be installed at positions that are apart from each other by a predetermined distance or more. By installing the environmental information acquisition devices at a predetermined distance or more in the room, the indoor environment can be measured efficiently and easily. The predetermined distance may be, for example, 50 cm, which is a distance at which a significant difference may occur in the environmental information acquired by the environmental information acquisition devices.

[0037] In FIG. 2, the third device 3 is shown as being installed in the corridor C (second room) at a third height L3 from the floor of the corridor C. However, this embodiment is not limited to this example. The third device 3 may be installed, for example, at a first height L1 or a second height L2 from the floor of the corridor C. That is, the third device 3 may be installed at the same height from the floor as the first device 1 or the second device 2. The environment information processing system 10 described later can measure the difference in environment between rooms by comparing the environment information acquired by the first device 1 installed at the first height L1 with the environment information acquired by the second device 2 installed at the second height L2.

[0038] The third device 3 is preferably installed at the same height from the floor as the second device 2. That is, the third device 3 is preferably installed at the second height L2 from the floor of the corridor C. When the first height L1 is close to the ankles, the second height L2 is higher than the first height, and is often close to parts that are easily affected by the indoor environment, such as the head and abdomen. By installing the third device 3 at the second height L2 from the floor, the difference between the environments of the first room and the second room can be measured based on the indoor environment (environmental information) felt by the occupant of the building. Since a height of 1.1 [m] from the floor corresponds to the height of the head when sitting on a chair and the height of the abdomen when standing, and a height of 1.7 [m] from the floor corresponds to the height of the head when standing, it is more preferable that the third device 3 is installed at a height of 1.1 [m] or 1.7 [m] from the floor.

[0039] Next, the environmental information processing system 10 according to this embodiment will be described with reference to FIGS.

[0040] FIG. 3 is an example of a block diagram of an environmental information processing system according to this embodiment. With reference to the figure, an example of an environmental information processing system 10 according to this embodiment will be described. The environmental information processing system 10 includes a first device 1, a second device 2, a third device 3, an environmental information processing device 30, and a presentation device 40. The first device 1, the second device 2, the third device 3, the environmental information processing device 30, and the presentation device 40 are connected via a network NW. When the first device 1, the second device 2, and the third device 3 are not distinguished from each other, they may be simply referred to as environmental information acquisition devices hereinafter. The network NW is a predetermined communication network configured using lines. An example of the network NW is the Internet. The predetermined communication network is an open network, and devices connected to the communication network can communicate with each other using a predetermined protocol. In the Internet layer of the communication network, communication is performed using the Internet Protocol (IP) or the like. The network NW includes a short-range communication network (PAN: Personal Area Network), a short-range communication network (WAN: Wide Area Network), LoRa (Long Range), etc. Furthermore, the network NW can use one or more of any communication methods such as infrared, wireless, Wi-Fi (registered trademark), a point-to-point (P2P) network, a telecommunication network, LTE (Long Term Evolution), Bluetooth (registered trademark), and BLE (Bluetooth Low Energy).

[0041] The first device 1 is an environmental information acquisition device installed in a first room at a first position at a first height L1 from the floor of the first room. The second device 2 is an environmental information acquisition device installed in a second position at a second height L2 from the floor of the first room. The third device 3 is an environmental information acquisition device installed in a third position at a third height L3 from the floor of the second room. Each environmental information acquisition device acquires at least two types of environmental information (hereinafter, may be referred to as first environmental information EI1 and second environmental information EI2). Each environmental information acquisition device transmits the acquired first environmental information EI1 and second environmental information EI2 to the environmental information processing device 30 via the network NW.

[0042] The environmental information processing device 30 acquires first environmental information EI1 and second environmental information EI2 from each of the environmental information acquisition devices. The environmental information processing device 30 performs calculations based on the values ​​of the first environmental information EI1 and the second environmental information EI2 acquired by the environmental information acquisition devices. The environmental information processing device 30 transmits calculation information CRI relating to the calculation results to the presentation device 40.

[0043] The presentation device 40 acquires the calculated information CRI from the environmental information processing device 30. The presentation device 40 presents the acquired calculated information CRI to a user. Here, the user may be, for example, a business entity that measures or evaluates the indoor environment of a building, or an owner or resident of the building.

[0044] 3 shows an example in which the environmental information processing device 30 and the presentation device 40 are connected via a network NW in the environmental information processing system 10. However, the present embodiment is not limited to this example. In the environmental information processing system 10, the environmental information processing device 30 may transmit the calculated information CRI to the presentation device 40 without going through the network NW (for example, the presentation device 40 is a display). Also, in the environmental information processing system 10, the environmental information processing device 30 and the presentation device 40 may be configured as a single device.

[0045] FIG. 4 is a functional configuration diagram for explaining an example of the functional configuration of the environmental information processing device according to the present embodiment. With reference to the same figure, an example of the functional configuration of the environmental information processing device 30 according to the embodiment will be described. The environmental information processing device 30 includes a first acquisition unit 31, a first association unit 32, a second acquisition unit 33, a second association unit 34, a third acquisition unit 35, a third association unit 36, a calculation unit 37, and a transmission unit 38. Each of these functional units is realized, for example, by using a computer and software. In addition, each functional unit may be realized by using an electronic circuit as necessary. Furthermore, each functional unit does not have to be included in a single device, and the environmental information processing device 30 may be configured by a plurality of devices.

[0046] The first acquisition unit 31 acquires the first environmental information EI1 and the second environmental information EI2 from the first device 1. The first acquisition unit 31 transmits the acquired first environmental information EI1 and second environmental information EI2 to the first association unit 32.

[0047] The first association unit 32 acquires the first environmental information EI1 and the second environmental information EI2 acquired by the first device 1 from the first acquisition unit 31. The first association unit 32 generates first correspondence information CI1 in which the acquired first environmental information EI1 and the second environmental information EI2 are associated with each other. The first correspondence information CI1 has, for example, an index indicated by the first environmental information EI1 as a first axis and an index indicated by the second environmental information EI2 as a second axis, and is information indicating a mutual correspondence relationship. The first association unit 32 transmits the generated first correspondence information CI1 to the calculation unit 37. Note that the first correspondence information CI1 may be in a format such as CSV (Comma Separated Value) as long as the first environmental information EI1 and the second environmental information EI2 are associated with each other. The second correspondence information CI2 and the third correspondence information CI3 described later are similar to the first correspondence information CI1.

[0048] The second acquisition unit 33 acquires the first environmental information EI1 and the second environmental information EI2 from the second device 2. The second acquisition unit 33 transmits the acquired first environmental information EI1 and second environmental information EI2 to the second association unit .

[0049] The second association unit 34 acquires the first environmental information EI1 and the second environmental information EI2 acquired by the second device 2 from the second acquisition unit 33. The second association unit 34 generates second correspondence information CI2 in which the acquired first environmental information EI1 and second environmental information EI2 are associated with each other. The second association unit 34 transmits the generated second correspondence information CI2 to the calculation unit 37.

[0050] The third acquisition unit 35 acquires the first environmental information EI1 and the second environmental information EI2 from the third device 3. The third acquisition unit 35 transmits the acquired first environmental information EI1 and second environmental information EI2 to the third association unit 36.

[0051] The third associating unit 36 ​​acquires the first environmental information EI1 and the second environmental information EI2 acquired by the third device 3 from the third acquiring unit 35. The third associating unit 36 ​​generates third association information CI3 in which the acquired first environmental information EI1 and second environmental information EI2 are associated with each other. The third associating unit 36 ​​transmits the generated third association information CI3 to the calculating unit 37.

[0052] The calculation unit 37 has a first calculation unit 371 and a second calculation unit 372 as components. The calculation unit 37 performs calculations using the first calculation unit 371 and the second calculation unit 372. The calculation unit 37 acquires first correspondence information CI1 from the first association unit 32. The calculation unit 37 acquires second correspondence information CI2 from the second association unit 34. The calculation unit 37 acquires third correspondence information CI3 from the third association unit 36. Note that when the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 are not to be distinguished from one another, they may be simply referred to as correspondence information CI hereinafter.

[0053] The first calculation unit 371 calculates a representative value from the value indicated by the first environmental information EI1 included in the corresponding information CI. Furthermore, the first calculation unit 371 calculates a representative value from the value indicated by the second environmental information EI2 included in the corresponding information CI. Note that the representative value is a value calculated by a predetermined algorithm for use in the second calculation unit 372. The representative value may include, for example, an average value, a median, a mode, a minimum value, a maximum value, etc. calculated by an arithmetic mean, a harmonic mean, etc.

[0054] The second calculation unit 372 performs calculations using the representative value calculated by the first calculation unit 371. First, in the information in which the index indicated by the first environmental information EI1 is the first axis and the index indicated by the second environmental information EI2 is the second axis, the representative point is a point indicated by the representative value of the value indicated by the first environmental information EI1 and the representative value of the value indicated by the second environmental information EI2 included in the correspondence information CI. In addition, in the information in which the index indicated by the first environmental information EI1 is the first axis and the index indicated by the second environmental information EI2 is the second axis, the representative point is a point determined or set in advance by the second calculation unit 372 (for example, a point indicating an ideal environment). The second calculation unit 372 calculates the value of the straight-line distance (Euclidean distance) connecting the representative point and the reference point for the correspondence information CI.

[0055] The calculation unit 37 transmits information on the result calculated by the second calculation unit 372 (hereinafter, may be referred to as calculation information CRI) to the transmission unit .

[0056] The transmission unit 38 acquires the calculation information CRI from the calculation unit 37. The transmission unit 38 transmits the acquired calculation information CRI to the presentation device 40.

[0057] The second calculation unit 372 calculates the value of the straight-line distance (Euclidean distance) connecting the representative point based on the corresponding information CI and the reference point. That is, the second calculation unit 372 can calculate a value indicating the degree of deviation between the environment on which the corresponding information CI is based (the environment around the environmental information acquisition device that acquired the environmental information on which the corresponding information CI is based) and an ideal environment. When the first calculation unit 371 calculates the representative point by the average value, median value, mode, or the like indicating the center of the distribution of the environmental information, the second calculation unit 372 can calculate a value indicating the degree of steady deviation between the current indoor environment and the ideal indoor environment. Specifically, when the environmental information acquisition device acquires environmental information on temperature, the environmental information processing system 10 can evaluate, for example, the insulation performance, etc. of the room in which the environmental information acquisition device is installed, according to the value calculated by the second calculation unit 372. When the environmental information acquisition device acquires environmental information on cleanliness, the environmental information processing system 10 can evaluate, for example, the ventilation rate of the room in which the environmental information acquisition device is installed, the ventilation performance of air conditioning equipment, etc., according to the value calculated by the second calculation unit 372. When the first calculation unit 371 calculates the representative point by the maximum or minimum value located at the end of the distribution of the environmental information, the second calculation unit 372 can calculate a value indicating the difference when the current indoor environment and the ideal indoor environment are most different. Specifically, when the environmental information acquisition device acquires environmental information on temperature, the environmental information processing system 10 can evaluate, for example, the risk of health damage such as heat shock or heat stroke in the room in which the environmental information acquisition device is installed, according to the value calculated by the second calculation unit 372. When the environmental information acquisition device acquires environmental information on carbon dioxide concentration, the environmental information processing system 10 can evaluate, for example, whether the room in which the environmental information acquisition device is installed is properly ventilated, according to the value calculated by the second calculation unit 372.

[0058] 5 is a flowchart for explaining an example of the flow of processing by the environmental information processing device 30 according to the present embodiment. With reference to the same figure, an example of the flow of processing by the environmental information processing device 30 according to the present embodiment will be described.

[0059] The environmental information processing device 30 acquires the first environmental information EI1 and the second environmental information EI2 from the environmental information acquisition devices (the first device 1, the second device 2, and the third device 3) installed in the first room and the second room, respectively (step S301). The environmental information processing device 30 generates corresponding information CI for each environmental information acquisition device based on the first environmental information EI1 and the second environmental information EI2 acquired by each environmental information acquisition device (step S302). The environmental information processing device 30 performs calculations using a predetermined calculation method based on the values ​​included in the corresponding information CI (step S303). The environmental information processing device 30 transmits calculation information CRI related to the calculation results to the presentation device 40 (step S304).

[0060] In this embodiment, an example is shown in which the second calculation unit 372 calculates the Euclidean distance between the representative point of the correspondence information CI and the reference point. However, this embodiment is not limited to this example. The second calculation unit 372 may calculate the value of the Euclidean distance between the representative value based on the first correspondence information CI1 and the representative value based on the second correspondence information CI2. It is known that people feel uncomfortable when the temperature in the vertical direction in a room is different, such as "the head is warm but the feet are cold" or "it is comfortable when sitting but it is muggy when standing". The first correspondence information CI1 and the second correspondence information CI2 are acquired by two environmental information acquisition devices installed at different heights from the floor in the same room. The second calculation unit 372 calculates the value of the Euclidean distance between the representative value based on the first correspondence information CI1 and the representative value based on the second correspondence information CI2, so that the environmental information processing system 10 can evaluate the difference in the vertical environment in the same room.

[0061] The second calculation unit 372 may calculate a value of the Euclidean distance between a representative value based on the first correspondence information CI1 or the second correspondence information CI2 and a representative value based on the third correspondence information CI3. The first correspondence information CI1 and the second correspondence information CI2 are acquired by an environmental information acquisition device installed in the first room. The third correspondence information CI3 is acquired by an environmental information acquisition device installed in the second room. When a person feels a sudden temperature difference, the risk of health damage such as heat shock increases, so caution is required when moving between an air-conditioned room and an unair-conditioned room. The second calculation unit 372 can calculate a value indicating the difference in environment between the two rooms by calculating a value of the Euclidean distance between the representative value based on the first correspondence information CI1 and the representative value based on the second correspondence information CI2. When the environmental information acquisition device acquires environmental information on temperature, the environmental information processing system 10 can evaluate the risk of health damage such as heat shock and heat stroke between the two rooms according to the value calculated by the second calculation unit 372.

[0062] The second calculation unit 372 may calculate a value according to the degree of dispersion of points (hereinafter, may be referred to as corresponding points) obtained by the correspondence relationship between the first environmental information EI1 and the second environmental information EI2 of a certain correspondence information CI. Here, the degree of dispersion is the degree of change in the environmental information acquired by the environmental information acquisition device. The degree of dispersion includes, for example, the moving distance of the corresponding points in a predetermined time (the integrated value of the difference when the corresponding points move) and the dispersion of the corresponding points in a predetermined time. When the environmental information acquisition device acquires environmental information on temperature, the environmental information processing system 10 can evaluate, for example, the usage status of the air conditioner according to the value calculated by the second calculation unit 372. Note that the predetermined time is, for example, 24 hours or more and 72 hours or less. When the predetermined time is 24 hours or more, the environmental information processing system 10 can measure the change in the environmental information caused by a series of actions taken by a person in a day. If it were possible to measure changes in environmental information that occur as a person performs a series of actions in a day, the reliability of the information presented by the environmental information processing system 10 would improve. If the specified time is 48 hours or more, the environmental information processing system 10 can ensure the reproducibility of changes in environmental information in a day by performing measurements for several days. If the specified time is 72 hours or less, the environmental information processing system 10 can reduce the energy consumed by measurements, reduce the processing burden associated with an increase in the amount of data, and reduce the psychological burden on residents caused by long-term measurements.

[0063] In the present embodiment, an example is shown in which the calculation unit 37 performs calculation based on the correspondence information CI acquired from the first association unit 32, the second association unit 34, and the third association unit 36. However, the present embodiment is not limited to this example, and the calculation unit 37 does not necessarily need to perform calculation based on the correspondence information CI. When the calculation unit 37 does not perform calculation based on the correspondence information CI, the first association unit 32, the second association unit 34, and the third association unit 36 ​​transmit the correspondence information CI to the transmission unit 38 without going through the calculation unit 37. The transmission unit 38 transmits the acquired correspondence information CI to the presentation device 40. The presentation device 40 presents the acquired correspondence information CI to the user.

[0064] Next, an example of a combination of environmental information will be described with reference to Fig. 6 to Fig. 10. In the description with reference to Fig. 6 to Fig. 10, the third correspondence information CI3 is information in which two types of environmental information acquired by an environmental information acquisition device installed at a second height L2 (the same height as the second device 2) from the floor of the second room are associated with each other.

[0065] FIG. 6 is a first diagram for explaining a combination of environmental information. The diagrams shown in FIG. 6(A) and FIG. 6(B) are information acquired by environmental information acquisition devices installed in two different buildings in summer. FIG. 6(A) and FIG. 6(B) are information in which the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3, which show the mutual correspondence, are combined, with the first axis (vertical axis) being room temperature [°C] and the second axis (horizontal axis) being relative humidity [%]. The plots of the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 shown in FIG. 6(A) are distributed over a wider range than the plots of the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 shown in FIG. 6(B). Since the plots are distributed over a wider range, it can be seen that the building from which the information shown in FIG. 6(A) is acquired is more susceptible to changes in room temperature and humidity than the building from which the information shown in FIG. 6(B) is acquired.

[0066] It is known that a comfortable room temperature is 25 to 28°C and a comfortable relative humidity is 60% or less in summer. Therefore, based on the combined environmental information of the room temperature and the relative humidity, the environmental information processing system 10 can, for example, evaluate the comfort of the room.

[0067] In FIG. 6(A), the room temperature is around 25-29°C, and the plot distributions of the first correspondence information CI1 and the second correspondence information CI2 overlap, so it can be seen that the first room has a small temperature difference in the vertical direction and a comfortable room temperature. In addition, in FIG. 6(A), the plots of relative humidity are widely distributed around 55-80%. This shows that the humidity is prone to change in the first and second rooms, that is, dehumidification or humidification is not performed appropriately. Furthermore, in FIG. 6(A), the room temperature indicated by the third correspondence information CI3 is at most 5°C different from the room temperature indicated by the first correspondence information CI1 and the second correspondence information CI2. Therefore, when moving between the first and second rooms, it is necessary to be careful of health hazards such as heat shock.

[0068] In Fig. 6(B), the room temperature values ​​are around 21-25°C, and the plot distribution is tight, so it can be seen that the first and second rooms have high insulation performance but are chilly due to reasons such as the air conditioning being too effective. Also, in Fig. 6(B), the relative humidity values ​​are 57-63%, and are around 60%, so it can be seen that the first and second rooms are dehumidified or humidified, and the humidity is appropriate.

[0069] FIG. 7 is a second diagram for explaining the combination of environmental information. The diagrams shown in FIG. 7(A) and FIG. 7(B) are information acquired by environmental information acquisition devices installed in two different buildings in winter. FIG. 7(A) and FIG. 7(B) are information in which the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3, which have room temperature [°C] as the first axis (vertical axis) and carbon dioxide concentration [ppm] as the second axis (horizontal axis), are combined, and the mutual correspondence relationship is shown. The plots of the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 shown in FIG. 7(A) are distributed over a wider range than the plots of the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 shown in FIG. 7(B). Since the plots are distributed over a wider range, it can be seen that the room temperature and carbon dioxide concentration are more likely to change in the building from which the information shown in FIG. 7(A) is acquired than in the building from which the information shown in FIG. 7(B) is acquired.

[0070] It is known that a comfortable room temperature in winter is 20 to 24°C. Carbon dioxide concentration is used as a guide to whether ventilation is being performed appropriately, and is preferably 1000 ppm or less. Therefore, based on information combining room temperature and carbon dioxide concentration, the environmental information processing system 10 can evaluate, for example, the ventilation performance and usage status of air conditioners.

[0071] In FIG. 7(A), the room temperature is low, about 7 to 20° C., so that the first and second rooms have low insulation performance or low air conditioner (heating) performance. In addition, in FIG. 7(A), the maximum carbon dioxide concentration is about 2500 to 5500 ppm, so that the first and second rooms have low ventilation performance of the air conditioner or the number of ventilations is insufficient. In addition, in FIG. 7(A), the room temperature indicated by the third correspondence information CI3 is about 7° C. different from the room temperature indicated by the first correspondence information CI1 and the second correspondence information CI2. Therefore, when moving between the first and second rooms, attention should be paid to health hazards such as heat shock.

[0072] In Fig. 7(B), the room temperature values ​​are around 22 to 26°C, and the plot distribution is tight, so it can be seen that the first and second rooms have high insulation performance and the performance of the installed air conditioners is high. Also, in Fig. 7(B), the maximum value of the carbon dioxide concentration value is around 1800 ppm, so it can be seen that the first and second rooms are more ventilated than the building in Fig. 7(A), but the ventilation is insufficient.

[0073] FIG. 8 is a third diagram for explaining the combination of environmental information. The diagrams shown in FIG. 8(A) and FIG. 8(B) are information acquired by environmental information acquisition devices installed in two different buildings. FIG. 8(A) and FIG. 8(B) are information in which the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3, which have illuminance [lx] as the first axis (vertical axis) and relative humidity [%] as the second axis (horizontal axis), and which show the mutual correspondence, are combined. The plots of the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 shown in FIG. 8(A) are distributed over a wider range than the plots of the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 shown in FIG. 8(B). Since the plots are distributed over a wider range, it can be seen that the building from which the information shown in FIG. 8(A) is acquired is more susceptible to changes in illuminance and humidity than the building from which the information shown in FIG. 8(B) is acquired.

[0074] It is known that the illuminance required for normal life is 150 to 300 [lx], the illuminance required for reading and general office work is 300 to 750 [lx], and the illuminance required for work that requires careful attention, such as handicrafts, is 1000 [lx] or more. Therefore, according to information including illuminance, the environmental information processing system 10 can evaluate, for example, the effects on health, such as eye strain and decreased eyesight, caused by working in an environment with insufficient brightness, and safety, such as operational mistakes and overlooking signs.

[0075] In FIG. 8(A), the illuminance value of the second correspondence information CI2 (second height L2 of the first room) is 750 [lx] or less, so it can be seen that the first room is an environment where general office work can be performed. Also, in FIG. 8(A), the illuminance value of the third correspondence information CI3 (second height L2 of the second room) is 1700 [lx] or less, so it can be seen that the second room is an environment where work that requires squinting can be performed. Furthermore, in FIG. 8(A), the relative humidity values ​​of the second correspondence information CI2 and the third correspondence information CI3 are 60 to 80 [%], so it can be seen that the humidity is high in the first room and the second room. Note that in FIG. 8(A), the plots of the second correspondence information CI2 and the third correspondence information CI3 are distributed over a wide range, so it can be seen that the first room and the second room are environments where the illuminance changes greatly.

[0076] In Fig. 8(B), the distribution of the plots of the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 is concentrated, so it can be seen that the first room and the second room are environments with little environmental change. Also, in Fig. 8(B), the illuminance value is 200 [lx] or less, so it can be seen that the brightness (lighting) of the first room and the second room may be insufficient. Furthermore, in Fig. 8(B), the humidity values ​​of the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 are about 50 to 60 [%], so it can be seen that the first room and the second room are dehumidified or humidified, and the humidity is appropriate.

[0077] FIG. 9 is a fourth diagram for explaining the combination of environmental information. The diagrams shown in FIG. 9(A) and FIG. 9(B) are information acquired by environmental information acquisition devices installed in two different buildings. FIG. 8(A) and FIG. 8(B) are information in which the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3, which have room temperature [°C] as the first axis (vertical axis) and illuminance [lx] as the second axis (horizontal axis), are combined, and the mutual correspondence relationship is shown. The plots of the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 shown in FIG. 9(A) are distributed over a wider range than the plots of the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 shown in FIG. 9(B). Since the plots are distributed over a wider range, it can be seen that the room temperature and illuminance of the building from which the information shown in FIG. 9(A) is acquired are more likely to change than the building from which the information shown in FIG. 9(B) is acquired. Therefore, based on the information combining room temperature and illuminance, the environmental information processing system 10 can evaluate the comfort of the room by taking into account not only the room temperature but also the radiant heat from the sun, for example, when the environmental information acquisition device is installed near a window.

[0078] Fig. 10 is a fifth diagram for explaining the combination of environmental information. Fig. 10(A) has carbon dioxide concentration [ppm] as the first axis (vertical axis) and illuminance [lx] as the second axis (horizontal axis), and is information showing the correspondence between them. According to the information in which the carbon dioxide concentration and illuminance are combined, the environmental information processing system 10 can, for example, evaluate whether the space in which the environmental information acquisition device is installed is suitable for plant growth.

[0079] 10B shows information showing the relationship between the average volume [dB] on the first axis (vertical axis) and the carbon dioxide concentration [ppm] on the second axis (horizontal axis). Using information combining volume and carbon dioxide concentration, the environmental information processing system 10 can evaluate, for example, the soundproofing of a recording studio, and the ventilation and noise reduction performance of air conditioning equipment installed in the recording studio.

[0080] FIG. 10(C) shows information indicating the correspondence between the atmospheric pressure [hPa] as the first axis (vertical axis) and the room temperature [°C] as the second axis (horizontal axis). It is generally known that changes in atmospheric pressure can affect physical conditions, such as causing migraines when the atmospheric pressure is low. Based on information combining the atmospheric pressure and the room temperature, the environmental information processing system 10 can, for example, evaluate the comfort of the space in which the environmental information acquisition device is installed.

[0081] FIG. 10(D) shows the room temperature [℃] on the first axis (vertical axis) and the total volatile organic compounds [μg / m 3 ] and the correspondence between them is shown. The total volatile organic compounds is a value obtained by the sum of all volatile organic compounds. Volatile organic compounds (e.g., formaldehyde, etc.) that are sometimes used in synthetic resin raw materials, building materials, adhesives, paints, surfactants, shrink-proofing of fibers, etc., may cause symptoms such as fatigue, dizziness, headache, eczema, sore throat, and respiratory diseases when inhaled in a certain amount or more. For this reason, there is a method (bake-out) in which the volatile organic compounds contained in building materials, furniture, etc. are diffused (volatilized) in the air by heating the room with a heating device, etc., and then ventilated and released outside, thereby reducing the volatile organic compounds contained in building materials, furniture, etc. According to the information in which the room temperature and the total volatile organic compounds are combined, the environmental information processing system 10 can, for example, evaluate the impact on health based on the amount of volatile organic compounds contained in the indoor air, observe the implementation status of bake-out, and evaluate the indoor environment after the implementation. In this way, according to the information in which any environmental information is combined, the indoor environment can be measured and evaluated according to the purpose.

[0082] FIG. 11 is a diagram for explaining an example of the correspondence information presented by the presentation device. FIG. 11 shows an example in which the presentation device 40 presents the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3, which have a first axis (vertical axis) of room temperature [°C] and a second axis (horizontal axis) of relative humidity [%] and show a mutual correspondence relationship. The ideal range IR is a range showing an ideal indoor environment (for example, a range of room temperature and relative humidity values ​​that are comfortable for people). From FIG. 11, it can be seen that the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 are shifted to the left of the ideal range IR. That is, it can be seen that the indoor environment shown in FIG. 11 is in a state of lower humidity than the ideal environment. The presentation device 40 may present a reference point, which is a point showing the ideal environment, instead of or in addition to the ideal range IR.

[0083] Also, from FIG. 11, it can be seen that the difference between the maximum temperature value of the first correspondence information CI1 and the maximum temperature value of the second correspondence information CI2 is 3° C. or less. When the temperature difference in the vertical direction is 3° C. or more, people tend to feel uncomfortable. Therefore, since the temperature difference between the top and bottom of the first room in which the first device 1 and the second device 2 are installed is 3° C. or less, it can be seen that the first room is a comfortable room in terms of temperature. By the presentation device 40 displaying a scatter diagram (two-dimensional information) as shown in FIG. 11, the user can easily evaluate the indoor environment using the difference in distribution of the correspondence information CI, the ideal range IR, the reference point, etc.

[0084] 11, the temperature values ​​in the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 vary widely from 16 to 24° C. Therefore, it can be seen that the building from which the information shown in FIG. 11 was obtained is in an environment where the room temperature is prone to change (for example, the insulation performance is low).

[0085] In this embodiment, an example is shown in which three environmental information acquisition devices are installed in a building. However, this embodiment is not limited to this example, and any number of environmental information acquisition devices may be installed in a building. By installing more environmental information acquisition devices, that is, by acquiring indoor environmental information in more detail, the environmental information processing system 10 can measure the indoor environment more accurately.

[0086] In this embodiment, an example is shown in which the environmental information acquisition device acquires two types of environmental information. However, this embodiment is not limited to this example. The environmental information acquisition device may acquire three or more types of environmental information. When the environmental information acquisition device acquires three or more types of environmental information, the association unit may generate correspondence information CI in which all of the acquired environmental information is associated with each other, or may generate correspondence information CI in which two or more types of environmental information are associated with each other among the acquired environmental information. By acquiring three or more types of environmental information, the environmental information processing system 10 can more accurately measure the indoor environment.

[0087] [Summary of this embodiment] According to the above-described embodiment, the environmental information processing system 10 is an environmental information acquisition device that acquires at least first environmental information EI1, which is information indicating values ​​of indices related to an indoor environment that changes over time, and second environmental information EI2, which is a type of index different from that of the first environmental information EI1, and includes a first device 1 that is installed at a first position in a first room, an environmental information acquisition device that is installed at a second position in the first room that is different in height from the first position from the height from the floor of the first room, an environmental information acquisition device that is installed at a third position in the second room that is a type different from that of the first room, and an environmental information acquisition device that is installed at a third position in the second room that is a type different from that of the first room. The environment information processing device 30 generates first correspondence information CI1 having an axis of an index indicated by the first environment information EI1 and an index indicated by the second environment information EI2 acquired by the second device 2, second correspondence information CI2 having an axis of an index indicated by the first environment information EI1 and an index indicated by the second environment information EI2 acquired by the second device 2, and third correspondence information CI3 having an axis of an index indicated by the first environment information EI1 and an index indicated by the second environment information EI2 acquired by the third device 3, and a presentation device 40 presenting a result based on at least one of the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 generated by the environment information processing device 30. According to this embodiment, the environment information processing system 10 acquires environment information by at least two environment information acquisition devices installed in the first room and at least one environment information processing device installed in the second room, and measures the indoor environment based on the acquired environment information. That is, two environmental information acquisition devices are installed in a room where a person stays for a long period of time, and one is installed in a room where a person stays for a short period of time or passes through without staying. By installing more environmental information acquisition devices in rooms where a person stays for a long period of time, the environmental information processing system 10 can more accurately measure the indoor environment of the room where a person stays for a long period of time. Furthermore, since the environmental information processing system 10 acquires environmental information by installing the environmental information acquisition devices in the first room and the second room, it does not require a huge amount of energy or complicated procedures to measure the indoor environment. Therefore, the environmental information processing system 10 according to this embodiment can measure the indoor environment with low energy and in a simple manner.

[0088] Furthermore, according to the above-described embodiment, in the environment information processing system 10, the environment information processing device 30 calculates the distance between a point obtained from one or more correspondence relationships between a value indicated by the first environment information EI1 and a value indicated by the second environment information EI2 included in any one of the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3, and an arbitrarily determined point (reference point). That is, the second calculation unit 372 can calculate a value indicating the degree of deviation between the environment on which the correspondence information CI is based (the environment around the environment information acquisition device that has acquired the environment information on which the correspondence information CI is based) and an ideal environment. Specifically, when the first calculation unit 371 calculates a representative point by an average value, a median value, a mode value, or the like indicating the center of the distribution of the environmental information, the second calculation unit 372 can calculate a value indicating the degree of steady deviation between the current indoor environment and the ideal indoor environment. Specifically, when the environmental information acquisition device acquires environmental information on temperature, the environmental information processing system 10 can evaluate, for example, the insulation performance, etc. of the room in which the environmental information acquisition device is installed, according to the value calculated by the second calculation unit 372. When the environmental information acquisition device acquires environmental information on cleanliness, the environmental information processing system 10 can evaluate, for example, the ventilation rate of the room in which the environmental information acquisition device is installed, the ventilation performance of air conditioning equipment, etc., according to the value calculated by the second calculation unit 372. Furthermore, when the first calculation unit 371 calculates the representative point by the maximum or minimum value located at the end of the distribution of the environmental information, the second calculation unit 372 can calculate a value indicating the difference when the current indoor environment and the ideal indoor environment are most different. Specifically, when the environmental information acquisition device acquires environmental information on temperature, the environmental information processing system 10 can evaluate, for example, the risk of health damage such as heat shock or heat stroke in the room in which the environmental information acquisition device is installed, according to the value calculated by the second calculation unit 372. When the environmental information acquisition device acquires environmental information on carbon dioxide concentration, the environmental information processing system 10 can evaluate, for example, whether the room in which the environmental information acquisition device is installed is properly ventilated, according to the value calculated by the second calculation unit 372. Therefore, the environmental information processing system 10 according to this embodiment can easily measure the indoor environment.

[0089] According to the above-described embodiment, in the environmental information processing system 10, the environmental information processing device 30 calculates a value according to the degree of dispersion of points within a predetermined time period, which is obtained from one or more correspondence relationships between a value indicated by the first environmental information EI1 and a value indicated by the second environmental information EI2 included in any one of the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3. When the environmental information acquisition device acquires environmental information on temperature, the environmental information processing system 10 can evaluate, for example, the performance and usage status of an air conditioner, according to the value calculated by the second calculation unit 372. Therefore, the environmental information processing system 10 according to this embodiment can easily measure the indoor environment.

[0090] According to the above-described embodiment, in the environment information processing system 10, the environment information processing device 30 calculates the distance between a point obtained from one or more correspondence relationships between the value indicated by the first environment information EI1 and the value indicated by the second environment information EI2 contained in the first correspondence information CI1, and a point obtained from one or more correspondence relationships between the value indicated by the first environment information EI1 and the value indicated by the second environment information EI2 contained in the second correspondence information CI2. It is known that people feel uncomfortable when the temperature in the vertical direction in a room is different, such as "the head is warm but the feet are cold" or "it is comfortable when sitting but it is muggy when standing". According to this embodiment, the first correspondence information CI1 and the second correspondence information CI2 are acquired by two environment information acquisition devices installed at different heights from the floor in the same room. The second calculation unit 372 calculates the Euclidean distance value between the representative value based on the first correspondence information CI1 and the representative value based on the second correspondence information CI2, so that the environment information processing system 10 can evaluate the difference in the environment in the vertical direction in the same room. Therefore, the environmental information processing system 10 according to this embodiment can easily measure the indoor environment.

[0091] According to the above-described embodiment, in the environmental information processing system 10, the environmental information processing device 30 calculates the distance between a point obtained from one or more correspondence relationships between the value indicated by the first environmental information EI1 and the value indicated by the second environmental information EI2 included in the first correspondence information CI1 or the second correspondence information CI2, and a point obtained from one or more correspondence relationships between the value indicated by the first environmental information EI1 and the value indicated by the second environmental information EI2 included in the third correspondence information CI3. When a person feels a sudden temperature difference, the risk of health damage such as heat shock increases, so caution is required when moving between an air-conditioned room and a non-air-conditioned room. According to this embodiment, the first correspondence information CI1 and the second correspondence information CI2 are acquired by an environmental information acquisition device installed in the first room. Moreover, the third correspondence information CI3 is acquired by an environmental information acquisition device installed in the second room. When the environmental information acquisition device acquires environmental information on temperature, the environmental information processing system 10 can evaluate the risk of health damage, such as heat shock or heat stroke, between two rooms in which the environmental information acquisition device is installed, based on the value calculated by the second calculation unit 372. Therefore, the environmental information processing system 10 according to this embodiment can easily measure the indoor environment.

[0092] According to the embodiment described above, the first correspondence information CI1, the second correspondence information CI2, and the third correspondence information CI3 are two-dimensional information in the environment information processing system 10. According to the environment information processing system 10 according to the embodiment, the presentation device 40 presents the two-dimensional correspondence information CI, so that the user can easily evaluate the indoor environment.

[0093] Furthermore, according to the above-described embodiment, in the environmental information processing system 10, the presentation device 40 presents information combining at least two pieces of information among the first corresponding information CI1, the second corresponding information CI2, and the third corresponding information CI3. By the environmental information processing system 10 according to the present embodiment presenting information combining a plurality of pieces of corresponding information CI, the user can easily compare the environmental information acquired by each environmental information acquisition device, i.e., the environment for each position in the building.

[0094] Furthermore, according to the above-described embodiment, in the environment information processing system 10, the third device 3 is installed at a position where the height from the floor of the second room is the same as the height from the floor of the first room of the first device 1 or the second device 2. According to this embodiment, the environment information processing system 10 can measure the difference in the environment between the rooms by comparing the environment information acquired by the first device 1 installed at the first height L1 with the environment information acquired by the second device 2 installed at the second height L2. Therefore, the environment information processing system 10 according to this embodiment can easily measure the indoor environment.

[0095] According to the above-described embodiment, in the environment information processing system 10, the first room is an occupied room, and the second room is a non-occupied room. In general, people in a building often move between occupied and non-occupied rooms. When the indoor environments of the occupied and non-occupied rooms are different (for example, the difference in the amount of dust, temperature, etc. is large), moving between the rooms with different indoor environments may be harmful to the health of the person moving between them. According to this embodiment, the environment information processing system 10 can measure the indoor environments of the two rooms and evaluate whether the indoor environments are different by installing the environment information acquisition device in the occupied and non-occupied rooms. Therefore, the environment information processing system 10 according to this embodiment can evaluate the risk of health damage to people in the building by comparing the indoor environments of the occupied and non-occupied rooms and measuring whether the indoor environments of the two rooms are different.

[0096] According to the above-described embodiment, in the environment information processing system 10, the index indicated by the first environment information EI1 is any one of the following types of index: temperature, humidity, carbon dioxide concentration, illuminance, cleanliness, volatile organic compound concentration, sound, and air pressure, and the index indicated by the second environment information EI2 is a different type of index from the first environment information: temperature, humidity, carbon dioxide concentration, illuminance, cleanliness, volatile organic compound concentration, sound, and air pressure. There are various types of indexes related to the indoor environment that change over time. According to this embodiment, the environment information processing system 10 can measure the indoor environment using environmental information of various types of indexes.

[0097] According to the above-described embodiment, the predetermined time is 24 hours or more and 72 hours or less in the environmental information processing system 10. When the predetermined time is 24 hours or more, the environmental information processing system 10 can measure changes in environmental information caused by a person's daily routine. If changes in environmental information caused by a person's daily routine can be measured, the reliability of the information presented by the environmental information processing system 10 can be improved. When the predetermined time is 48 hours or more, the environmental information processing system 10 can ensure reproducibility of changes in daily environmental information by performing measurements for several days. When the predetermined time is 72 hours or less, the environmental information processing system 10 can reduce the energy consumed by the measurement, reduce the processing load associated with an increase in the amount of data, and reduce the psychological burden on the resident due to long-term measurement. Therefore, the environmental information processing system 10 according to this embodiment can measure the indoor environment with low energy and easily while taking into account changes in environmental information caused by daily life.

[0098] In the above description, an example of the environmental information processing system 10 evaluating an indoor environment using three or more environmental information acquisition devices (the first device 1, the second device 2, and the third device 3) is shown. However, the environmental information processing system 10 according to the present embodiment is not limited to this example, and may evaluate an indoor environment using two environmental information processing devices. For example, the environmental information processing system 10 may evaluate an indoor environment using two environmental information acquisition devices installed in one room (e.g., a living room), or may evaluate an indoor environment using a total of two environmental information acquisition devices installed in two rooms (e.g., a living room and a non-living room). When installing a total of two environmental information acquisition devices, one in each of the two rooms, it is preferable that the environmental information acquisition devices are installed so that their heights from the floor are approximately the same. It is more preferable to use three or more environmental information acquisition devices in order to more accurately evaluate the indoor environment.

[0099] In the above description, the environmental information acquisition devices are shown as being installed as separate devices, such as the first device 1, the second device 2, and the third device 3. However, the present embodiment is not limited to this example, and functions realized by two or more environmental information acquisition devices may be realized by one environmental information acquisition device. That is, the environmental information processing system 10 according to the embodiment may realize the functions of two or more environmental information acquisition devices among the first device 1, the second device 2, and the third device 3 by one environmental information acquisition device.

[0100] In the above description, an example is shown in which the first position where the first device 1 is installed and the second position where the second device 2 is installed are different in height from the floor of the room. Here, "different heights from the floor" is an example of positions where the environments in the room are different from each other. That is, the first device 1 and the second device 2 only need to be installed in different environments, and the first position where the first device 1 is installed and the second position where the second device 2 is installed may be the same in height from the floor. For example, the first position and the second position may be different in positions in the horizontal direction. Furthermore, for example, if the room is a living room, the first position may be near the center of the room and the second position may be near a window or near an entrance of the room, or if the room is a non-living room, the first position may be in the bathroom and the second position may be in the dressing room.

[0101] In addition, all or part of the functions of each unit of the environmental information processing system 10 in the above-mentioned embodiment may be realized by recording a program for realizing these functions on a computer-readable recording medium, reading the program recorded on the recording medium into a computer system, and executing it. Note that the "computer system" referred to here includes hardware such as an OS and peripheral devices.

[0102] Furthermore, the term "computer-readable recording medium" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, and recording units such as hard disks built into computer systems. Furthermore, the term "computer-readable recording medium" may also include those that dynamically hold a program for a short period of time, such as a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line, and those that hold a program for a certain period of time, such as a volatile memory inside a computer system that serves as a server or client in such cases. Furthermore, the above-mentioned program may be one that realizes part of the above-mentioned functions, or may be one that can realize the above-mentioned functions in combination with a program already recorded in the computer system.

[0103] Although one embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to the above, and various design changes and the like are possible without departing from the scope of the present invention. In addition, the configurations described in the above-mentioned embodiments and examples may be combined. [Explanation of symbols]
