Abstract
Description
[Technical Field]
[0001] This invention relates to a device control system. [Background technology]
[0002] With the increasing airtightness and insulation of homes, and furthermore, the increase in time spent at home since the spring of 2020, changes in lifestyles are demanding changes in the way we live, as well as in the desired plans and performance levels of our homes.
[0003] The air conditioning system described in Patent Document 1 includes a heat source unit configured to generate thermal energy to be supplied to a controlled area, a plurality of air conditioning units configured to distribute the thermal energy generated by the heat source unit to a plurality of areas within the controlled area, and a predictive control unit configured to control the starting and stopping of the heat source unit and the starting and stopping of each air conditioning unit in order to improve comfort while people are in each room, based on association information that associates each of the partitioned rooms in the controlled area with the air conditioning units, weather information, information on the occupants of each room, and the set temperature of each air conditioning unit (see Patent Document 1). [Prior art documents] [Patent Documents]
[0004] [Patent Document 1] Japanese Patent Publication No. 2020-070945 [Overview of the Initiative] [Problems that the invention aims to solve]
[0005] However, in the technology described in Patent Document 1, there were cases where the indoor environment was not sufficiently reflected in the air conditioning control. For example, in buildings such as detached houses, the room temperature and indoor illumination change over time due to changes in the amount of solar radiation (solar heat) received from the sun. Furthermore, because each building has different insulation performance, window size, shape, and layout, the amount of solar radiation and indoor illumination that changes over time also differs from building to building.
[0006] For example, when predictive control was performed based solely on resident information and set temperatures, it was difficult to improve comfort while suppressing power consumption. Furthermore, when environmental control equipment was operated after a change in the indoor environment, it was difficult to suppress changes in the indoor thermal environment. Furthermore, in order to control equipment while suppressing power consumption, it was necessary to optimize conflicting parameters.
[0007] This invention was made in consideration of these circumstances, and aims to provide an equipment control system that can control equipment to create a comfortable indoor environment while suppressing power consumption. [Means for solving the problem]
[0008] As an example configuration, the device control system comprises a detection unit that detects one or more of the following for a room to be controlled: humidity, brightness, sound level, odor component concentration, chemical substance concentration, amount of clothing worn by the user, or the user's activity level, as well as control content specified by the user to be executed with the highest priority, control content specified by the user not to be executed, room temperature, and outside temperature; and a control unit that controls equipment affecting the room temperature based on the detection results of the detection unit. [Effects of the Invention]
[0009] According to the equipment control system of the present invention, it is possible to control equipment in a way that makes the indoor environment comfortable while suppressing power consumption. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention
[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012] [Device Control System] FIG. 1 is a diagram showing an example of the configuration of a device control system 1 according to the embodiment. The device control system 1 includes a detection unit 11, a device unit 12, a device control device 13, a management device 31, and an information providing unit 51.
[0013] In the present embodiment, the detection unit 11, the device unit 12, and the device control device 13 are provided in the indoor area R1. Also, the management device 31 and the information providing unit 51 are provided outside the indoor area R1. In the present embodiment, the device control system 1 controls devices for adjusting the environment of the indoor area R1.
[0014] Here, interior R1 represents part or all of the interior of a given building. For example, interior R1 may be the interior of one room in a given building, the interiors of two or more rooms in the same building, or the entire interior of a given building. The designated building may be any building, for example, a private house, an apartment building, or a commercial building.
[0015] Furthermore, in this embodiment, the occupant of room R1 is assumed to be the user of the equipment control system 1. In other words, in this embodiment, the equipment control system 1 controls the system to create a comfortable living environment for the resident. Furthermore, depending on the room R1 to which the equipment control system 1 is applied, various individuals may be set as users.
[0016] In this embodiment, the management device 31 is a server device installed on the internet or elsewhere, and is a so-called cloud device. In another configuration example, some or all of the functions of the management device 31 may be provided in room R1. In this embodiment, if the management device 31 is configured as a cloud device, for example, the communication environment between the equipment control device 13 and the management device 31 may be a communication environment independent of other communication environments in the room R1 (e.g., the internet environment). Furthermore, if the management device 31 is configured as a cloud device, the management device 31 may perform processes to monitor the operation of the equipment control device 13 (processing of the operation monitoring service). The management device 31 may, for example, manage the status of the equipment control device 13, or perform controls to restart or update the equipment control device 13.
[0017] In this embodiment, the information provision unit 51 is installed in an organization that provides predetermined information, such as the Japan Meteorological Agency, which provides weather information. The information provision unit 51 may, for example, communicate with one or both of the equipment control device 13 and the management device 31 via an API (Application Programming Interface). As an alternative configuration, some or all of the functions of the information provision unit 51 may be provided in the room R1.
[0018] As in this embodiment, when the equipment control system 1 is composed of multiple devices, communication is performed between one device and other devices as needed. For example, this communication may be wired or wireless.
[0019] Note that the example in Figure 1 shows one configuration example illustrating the location where each function of the equipment control system 1 is provided, and other arbitrary configurations may be used.
[0020] For example, the management device 31 may be considered an external functional unit of the equipment control system 1, in which case the equipment control system 1 may be considered not to include the management device 31. For example, the information provision unit 51 may be considered an external functional unit of the equipment control system 1, in which case the equipment control system 1 may be considered not to have the information provision unit 51. In this embodiment, we show a case where information provided by the information provision unit 51 is used, but there may be cases where such information is not used.
[0021] <Detection Unit> The detection unit 11 detects predetermined information. In this embodiment, the predetermined information is information referenced to adjust the environment of indoor R1, and is, for example, information representing the state of the environment of indoor R1, or information representing the external state (external to indoor R1) that affects the environment of indoor R1.
[0022] Specific examples of the information to be detected include temperature information, humidity information, brightness information, sound level information, odor component concentration information, chemical substance concentration information, solar radiation gain information, ventilation rate information, power consumption information (which may also be called energy consumption), gas usage information, and water usage information.
[0023] The temperature information used will include the indoor temperature of room R1 and the outdoor temperature. The unit of temperature may be [°C] (Celsius). The humidity information used is that of the indoor R1. Alternatively, the humidity information may be in the form of relative humidity [%], or absolute humidity [g / m³]. 3 The information in ] may be used.
[0024] For brightness information, the brightness information of the room R1 is used. For brightness information, for example, illuminance [lx] information may be used, or luminance [cd / m²]. 2 The information in ] may be used. The sound intensity information used is that of the sound in room R1 (which may include sounds arriving from outside). The unit of sound intensity may be [dB] or [sone]. In addition, the sound intensity information may be expressed as sound strength [W / m 2 Information in the format [Pa] may be used, or information in the format [Pa] may be used.
[0025] The information used for odor component concentration is the odor component concentration of indoor R1. The unit for odor component concentration may be [ppm] or similar. The information used for chemical substance concentrations is that of indoor R1. Units such as [ppm] may be used for chemical substance concentrations. Carbon dioxide concentration may be used as an example of a chemical substance concentration.
[0026] The information used for solar radiation gain is the amount of solar radiation gained in room R1. The amount of solar radiation gained in room R1 is, for example, the amount of solar radiation entering room R1 through a window or other opening in room R1. The unit of solar radiation gain is [W / m²]. 2 ] may be used. Furthermore, information on the amount of solar heat gain may be used as the information on the amount of solar radiation gained.
[0027] The ventilation rate information used is that of indoor R1. The unit of ventilation rate is [m 3 / h] may also be used. The power consumption information used is that of one or more predetermined devices used in room R1. These devices may be, for example, devices controlled by the device control unit 115, or other devices (referred to as uncontrolled devices for convenience of explanation). Alternatively, the total power consumption for room R1 may be used as the power consumption. The unit of power consumption may be [Wh] or similar.
[0028] The gas usage information used is the amount of gas used indoors with R1. The unit of gas usage is [m³ 3 ] and other similar terms may also be used. The water usage information used will be the amount of water used in indoor R1. The unit of water usage will be [m³] 3 ] and other similar terms may also be used.
[0029] Furthermore, as a specific example, the predetermined information to be detected may include information on the amount of clothing worn by the resident, information on the amount of exercise (which may also be called activity level), information on the resident's biological information, information on the resident's daily activities (behavior), information on the resident's daily rhythm, and information on the resident's location.
[0030] Information on the amount of clothing a resident is wearing may be, for example, information detected by a sensor attached to the resident. Specifically, information on the amount of clothing a resident is wearing may be information detected by a sensor that detects identification information attached to the resident's clothing. Specifically, information on the amount of clothing a resident is wearing may be information corresponding to the weight of the clothing attached to the resident, or information corresponding to the number of pieces of clothing attached to the resident. As another example, information on the amount of clothing a resident is wearing may be detected based on imaging results from a camera (an example of a sensor) that images the resident or other locations. As another example, information on the amount of clothing a resident is wearing may be detected based on information manually entered by the resident or another person (for example, a caregiver for the resident).
[0031] Information on the residents' movement may be obtained, for example, from a sensor that detects the residents' movements. This sensor may be attached to the residents, or it may be a camera (an example of a sensor) that images the residents.
[0032] The resident's biological information may be detected, for example, by sensors attached to the resident. This biological information may include, for example, body temperature, heart rate, and respiratory rate. Information about the resident's daily activities may be detected, for example, by a sensor installed in room R1. This information may include, for example, information about bathing, using the toilet, and washing up. Information about the resident's daily rhythm may be detected, for example, by sensors worn by the resident or by sensors installed in room R1. Information about the resident's daily rhythm may include, for example, information about waking up, going to bed, eating, bathing, using the toilet, and washing face.
[0033] Here, information on the residents' physical activity levels may be detected (e.g., estimated) based on one or more of the following: information on the residents' biological activity, information on the residents' daily activities, information on the residents' daily rhythms, etc.
[0034] Information about the resident's location may be detected, for example, by a sensor installed in room R1. This sensor may be a camera (an example of a sensor). As a specific example, the predetermined information to be detected may be information indicating whether or not a resident is present in room R1 (presence / absence information).
[0035] Here, whether or not an occupant is present in room R1 may be detected by any method. For example, a method may be used to detect (determine) whether or not a person (in this case, a resident) is present in room R1 using a motion sensor installed in room R1.
[0036] As another example, a method may be used in which an operating unit such as a button operated by the resident is provided in room R1, and whether or not a resident is present in room R1 is detected (determined) based on the signal output in response to the operation of the operating unit. In this case, the control unit has, for example, an operating state that indicates that a resident is present in room R1, and an operating state that indicates that a resident is not present in room R1. The resident operates the control unit when leaving room R1 to the outside, and when entering room R1 from the outside, etc.
[0037] As another example, a method may be used to detect (determine) whether or not there is an occupant in room R1 based on the power consumption of one or more devices that are expected to be used by the occupant. In this case, for example, if the power consumption of the equipment exceeds a predetermined threshold during a predetermined period, it may be determined that there is an occupant in room R1.
[0038] Furthermore, as a specific example, the information to be detected may be information relating to the residents' preferences (which may also be called tastes, etc.). Resident preferences include, for example, the content that residents desire, and specific examples may include control actions they wish to be performed with the highest priority, control actions they wish not to be performed, desired values for any physical quantity such as temperature or humidity, and the effective range of various parameters. Furthermore, as a detection unit for detecting such information, for example, an operating unit that is operated by the resident and accepts the resident's preferences may be used. This operating unit may be, for example, a button, key, mouse, touch panel, voice input unit, etc.
[0039] Furthermore, as a specific example, the predetermined information to be detected may be the settings configured by the resident. The settings set by the resident may include, for example, temperature or humidity settings for equipment such as air conditioners. The settings may include, for example, a set value, or other settings. Furthermore, as a detection unit for detecting such information, a sensor that detects settings for equipment such as an air conditioner may be used.
[0040] Furthermore, as a specific example, the predetermined information to be detected may be information representing the content of tasks related to the living environment that were performed manually by the residents. Examples of such tasks may include opening and closing windows (opening windows, closing windows), opening and closing blinds, opening and closing shutters, and turning lights on and off (turning lights on, turning lights off). For example, a sensor that detects the details of work performed on a window or the like may be used as the detection unit for detecting such information.
[0041] Here, the detection unit 11 is equipped with, for example, a sensor for detecting each piece of information to be detected. Furthermore, for the same type of physical quantity (for example, a physical quantity of the type room temperature, or another type of physical quantity), a sensor for detecting that physical quantity may be provided at one location in the room R1 (i.e., a total of one sensor), or sensors for detecting that physical quantity may be provided at two or more different locations in the room R1 (two or more different measurement points) (i.e., a total of two or more sensors). The detection unit 11 may also be equipped with a multi-sensor that detects two or more types of information.
[0042] <Control device> The device control device 13 may be configured, for example, as a gateway device. The device control device 13 includes a detection information acquisition unit 111, an external information acquisition unit 112, an information transmission unit 113, an information reception unit 114, and a device control unit 115. The detection information acquisition unit 111 acquires the information detected by the detection unit 11. The external information acquisition unit 112 acquires information provided by the information provision unit 51.
[0043] Here, the timing for the detection information acquisition unit 111 to acquire the information detected by the detection unit 11 and the timing for the external information acquisition unit 112 to acquire the information provided by the information provision unit 51 can be any timing, for example, periodic timings may be used. Furthermore, these timings may be the same, or they may be different.
[0044] The information transmission unit 113 transmits predetermined information to the management device 31. In this embodiment, the predetermined information may include some or all of the information detected by the detection unit 11, and may also include some or all of the information representing the control status of the device unit 12 (which may also be called the control status). The information representing the control status of the device unit 12 may include information on the control values set for the device unit 12, and may also include information representing the history of control performed on the device unit 12. Furthermore, the information representing the control status of the device unit 12 may also include information representing the state of the device unit 12 (the state resulting from the control). Note that the information representing the control status of the device unit 12 may also be information for each device included in the device unit 12.
[0045] The information receiving unit 114 receives information transmitted from the management device 31. The device control unit 115 has the function of controlling the device unit 12. The device control unit 115 controls the device unit 12 based on predetermined information. In this embodiment, the device control unit 115 controls the device unit 12 by outputting a value (control value) for controlling the device unit 12 to the device unit 12. In this embodiment, the predetermined information may include some or all of the information received by the information receiving unit 114. Furthermore, in this embodiment, the predetermined information may include some or all of the information detected by the detection unit 11. Furthermore, in this embodiment, the predetermined information may include some or all of the information acquired by the external information acquisition unit 112, and may also include information inferred from such information.
[0046] Furthermore, the specified information may also include information that serves as a reference for controlling the equipment unit 12 (referred to as equipment control reference information for convenience of explanation). As equipment control reference information, for example, generally known information may be used, or information uniquely set for each equipment control system 1 may be used.
[0047] Generally known information, such as thermal or illuminance-related indicators for determining a comfortable temperature range, may be used. As a specific example, the standard effective temperature (SET) such as the comfortable temperature and humidity range according to ASHRAE 55-2004. * ) may be used as a comfort zone determination index. Standard effective temperature (SET* ) is an index for judging comfort zones based on a mathematical model that simulates the relationship between the amount of heat dissipation from the human body, environmental factors, and physiological factors, as well as the physiological body temperature regulation function. There are comfort zone judgment indicators for summer, winter, etc.
[0048] In addition, the comfort zone judgment index for illuminance may be switched so that different comfort zone judgment indexes are used depending on whether the occupant is present in the indoor area R1 (while in the room) or not present in the indoor area R1 (absent).
[0049] Note that the comfort zone judgment index is not limited to the above. For example, as a thermal comfort judgment index, Predicted Mean Vote (PMV), operative temperature, or room temperature may be used. In addition, as a comfort judgment index for illuminance, the illuminance standard defined in JIS Z9110, brightness perception, etc. may be used. In addition, as other comfort judgment indexes, humidity, discomfort index, sound pressure level of noise, or CO2 concentration may be used.
[0050] In addition, the device control unit 115 manages information representing the control state of the device unit 12. The device control unit 115 has a function of acquiring information representing the state of the device unit 12 from the device unit 12.
[0051] Here, the device control unit 115 may be configured using a processor such as a CPU (Central Processing Unit). In this case, the device control unit 115 controls the device unit 12 by executing a control program by the processor. Note that the device control unit 115 may include a storage unit for storing various types of information. The information may be, for example, a control program, information representing the control state of the device unit 12, information serving as a reference for controlling the device unit 12, etc.
[0052] Furthermore, the device control unit 115 may determine a value (control value) for controlling the device unit 12 based, for example, on the results of machine learning that has already been performed. In this case, the results of the machine learning may be stored in any memory unit, for example, in the memory unit of the device control unit 115 if the device control unit 115 is equipped with a memory unit.
[0053] <Equipment section> The equipment unit 12 includes one or more pieces of equipment. In this embodiment, the device has a function that affects the room temperature of the room R1, and is installed, for example, in the room R1 or outside the room R1.
[0054] As a specific example, the equipment included in the equipment section 12 includes air conditioning equipment such as air conditioners for adjusting lighting, temperature, or humidity, floor heating equipment, ventilation equipment for adjusting humidity, electric blinds (e.g., external electric blinds, internal electric blinds), electric roller screens (e.g., external electric roller screens, internal electric roller screens), electric shutters, etc. Furthermore, the equipment unit 12 may also include household appliances that generate heat or humidity, in addition to those mentioned above. Such household appliances may be dishwashers or hair dryers, etc.
[0055] Lighting control methods include, for example, turning the lights on and off, and further, controlling the brightness when the lights are on. Control modes for air conditioning equipment include, for example, cooling, heating, ventilation, and dehumidification, as well as set temperature, set humidity, wind direction, and wind speed. The control modes for underfloor heating include, for example, on and off, and further, the areas in which the underfloor heating is turned on, the power level, etc. One way to control the blinds is by adjusting the opening and closing angle. Examples of opening and closing angles include fully open, half-open, or fully closed. One control method for a roller screen is the degree of opening or closing. The degree of opening or closing may include fully open, half-open, or fully closed. One example of a shutter control method is the degree of opening or closing. The degree of opening or closing may include fully open, half-open, or fully closed.
[0056] Furthermore, multiple devices of the same type (for example, lighting or air conditioners) may be included in the device section 12. Each piece of equipment may, for example, be equipment that is already installed in the building where Room R1 is located, or it may be equipment purchased by a resident of the building or someone similar. Furthermore, each piece of equipment may be, for example, exclusively installed in room R1, or it may be installed in room R1 and other rooms in common, or it may be installed throughout the entire building where room R1 is located (for use throughout the entire building).
[0057] Each device in the equipment unit 12 operates based on instructions (control values in this embodiment) from the equipment control unit 115. Here, the equipment control unit 115 can control one or more of the devices included in the equipment unit 12. The device control unit 115 can, for example, control two or more devices in coordination, or it can also control two or more devices independently.
[0058] <Management device> The management device 31 includes an information receiving unit 211, an external information acquisition unit 212, a storage unit 213, a control target value determination unit 214, and an information transmission unit 215. The information receiving unit 211 receives information transmitted from the equipment control device 13. The external information acquisition unit 212 receives information provided by the information provision unit 51.
[0059] Here, the timing for receiving information transmitted from the device control unit 13 by the information receiving unit 211 (i.e., the timing for transmitting information from the device control unit 113) and the timing for receiving information provided by the information providing unit 51 by the external information acquisition unit 212 can be any timing, for example, periodic timings may be used. Furthermore, these timings may be the same, or they may be different.
[0060] The memory unit 213 stores predetermined information. In this embodiment, the predetermined information may include, for example, information received by the information receiving unit 211. Furthermore, in this embodiment, the predetermined information may include, for example, information acquired by the external information acquisition unit 212.
[0061] In this embodiment, the storage unit 213 stores sensor information detected by the detection unit 11 (for example, information such as the indoor environment), equipment operation logs (equipment operation logs) related to the equipment of the equipment unit 12, and information provided by the information provision unit 51. This information pertains to the living environment state of the controlled indoor space R1, and will be used to perform living environment prediction simulations.
[0062] The control target value determination unit 214 determines the control target value based on the information stored in the storage unit 213. In this embodiment, the information is, for example, information stored in the storage unit 213, and may include information received by the information receiving unit 211, information acquired by the external information acquisition unit 212, or information inferred from the information acquired by the external information acquisition unit 212.
[0063] Here, the control target value determination unit 214 may include information that serves as a criterion for determining the control target value (for convenience of explanation, this will be called control target value determination criterion information). As the control target value determination criterion information, for example, generally known information may be used, or information uniquely set for each equipment control system 1 may be used. Generally known information, such as information that serves as a comfort zone determination index related to thermal or illuminance, may be used. This information may be similar to the information described with respect to the equipment control unit 115.
[0064] In this embodiment, the comfort zone judgment index may be used in either the control target value determination unit 214 or the equipment control unit 115, or it may be used in both.
[0065] In this embodiment, the control target value determined by the control target value determination unit 214 is a target value for controlling the equipment included in the equipment unit 12. As a specific example, the control target value may be a control target value such as temperature (room temperature in this embodiment), humidity, illuminance (indoor illuminance in this embodiment), or power consumption.
[0066] In this embodiment, the control target value determination unit 214 has a function to perform a living environment prediction simulation. Based on the information stored in the storage unit 213, it performs a living environment prediction simulation and determines a control target value for controlling the living environment based on the results. In this case, the target of prediction using the living environment prediction simulation is, for example, the change in indoor temperature R1.
[0067] Here, the control target value determination unit 214 may be configured using a processor such as a CPU. In this case, the control target value determination unit 214 determines the control target value by executing a control program using the processor. The control target value determination unit 214 may also include a storage unit for storing various types of information. This information may include, for example, a control program or control target value determination criterion information. The storage unit 213 may be used as the storage unit.
[0068] Furthermore, the control target value determination unit 214 may determine the control target value based, for example, on the results of machine learning that has already been performed. In this case, the results of the machine learning may be stored in any memory unit, for example, in the memory unit 213, or in the memory unit if the control target value determination unit 214 is equipped with a memory unit.
[0069] In this embodiment, in the default state of the equipment control system 1 (in this case, the management device 31), the control target value is set to fall within a predetermined comfort standard range (i.e., within that comfort standard range). As the predetermined comfort standard range, for example, one or more generally known comfort standard indicators may be used, or a comfort standard range that is uniquely set for each equipment control system 1 (in this case, each management device 31) may be used.
[0070] Furthermore, in this embodiment, the default predetermined comfort standard range can be changed. In this embodiment, the reference range after the default predetermined comfort reference range has been changed will be referred to as the comfort range. This comfort range is used as the reference range within which the target value should fall, and is used after being modified from the default comfort reference range.
[0071] This comfort zone can be set based on the preferences of the residents. As an example, the equipment control system 1 includes an input function unit for manually inputting information for setting the comfort zone (which may also be information about the comfort zone itself) by the resident or their representative (for example, a caregiver for the resident). This input function unit may be configured using, for example, a keyboard, mouse, buttons, or a touch panel. The functions of this input function unit may be configured, for example, as part of the functions of a computer. In this embodiment, the comfort zone, which is manually entered by the resident or their representative, is based on the resident's preferences.
[0072] Furthermore, the device control system 1 includes a setting function unit that sets the comfort zone based on the information input by the input function unit. In the example shown in Figure 1, the input function unit is located in room R1. For example, the input function unit may be included in the detection unit 11, or it may be included in the equipment control device 13. The information transmission unit 113 of the equipment control device 13 transmits the information input by the input function unit to the information receiving unit 211 of the management device 31. In the example shown in Figure 1, the setting function unit is provided in the management device 31. The setting function unit may store information about the set comfort range in the storage unit 213. For example, the setting function unit may be included in the control target value determination unit 214. The control target value determination unit 214 may, by default, determine the control target value by referring to the comfort standard range, and if the default comfort standard range is changed to a comfort range, it may determine the control target value by referring to that comfort range.
[0073] As another example, the equipment control system 1 may acquire information for setting the comfort zone based on the detection results of a sensor that detects information about the resident's preferences (rather than direct input from the resident, etc.). The sensor may be included in the detection unit 11. For example, the sensor may be one that detects information about the resident's clothing, food, or daily rhythm. Furthermore, as another example, the equipment control system 1 may set a comfort zone based on both the information input by the input function unit and the information detected by the sensor.
[0074] In this embodiment, the control target value can be set based on the preferences of the residents. For example, if the control target value is set based on the comfort zone, then by setting the comfort zone based on the residents' preferences, the control target value is effectively set based on the residents' preferences.
[0075] Furthermore, the control target value may be set based on the comfort zone, as described above, or, as another example, not based on the comfort zone but based on the residents' preferences. As an example, the equipment control system 1 includes an input function unit that allows a resident or their representative (for example, a caregiver for the resident) to manually input information for setting the control target value (which may also be information about the control target value itself). Furthermore, the device control system 1 includes a setting function unit that sets the control target value based on the information input by the input function unit. As another example, the equipment control system 1 may acquire information for setting the control target value based on the detection results of a sensor that detects information about the resident's preferences (rather than direct input from the resident, etc.). The sensor may be included in the detection unit 11. Furthermore, as another example, the device control system 1 may set a control target value based on both the information input by the input function unit and the information detected by the sensor.
[0076] Furthermore, the details of the input function unit and setting function unit related to the control target value may be the same as those described for the input function unit and setting function unit for the comfort range, or other configurations may be used.
[0077] The information transmission unit 215 transmits predetermined information to the device control device 13. In this embodiment, the predetermined information may include information on the control target value determined by the control target value determination unit 214.
[0078] <Information Department> The information provision unit 51 has the function of providing predetermined information. The information provision unit 51 may be configured using, for example, a database. In this embodiment, the predetermined information may include meteorological information. Meteorological information may include, for example, outside temperature, weather (cloud cover, etc.), solar radiation, or solar altitude and azimuth angle. Weather information may include, for example, any one or more of the following: future weather information (weather forecast information), current weather information, and past weather information.
[0079] For example, the functions of the management device 31 and the equipment control device 13 may be integrated. In this case, the information transmission unit 113 of the equipment control device 13 and the information receiving unit 211 of the management device 31, and the information transmission unit 215 of the management device 31 and the information receiving unit 114 of the equipment control device 13 may not be provided. Also in this case, the external information acquisition unit 112 of the equipment control device 13 and the external information acquisition unit 212 of the management device 31 may be shared into a single functional unit (external information acquisition unit).
[0080] [Examples of operation in equipment control systems] An example of the operations performed in the equipment control system 1 is shown. In room R1, the equipment control device 13 acquires detection information, which is the detection result of the detection unit 11, using the detection information acquisition unit 111. The device control unit 13 then transmits the detection information to the management device 31 via the information transmission unit 113. At this time, the device control unit 13 also transmits information representing the control status of the device unit 12 to the management device 31 via the information transmission unit 113.
[0081] The management device 31 receives information transmitted from the equipment control device 13 via the information receiving unit 211. The management device 31 also receives and acquires information provided by the information providing unit 51 via the external information acquisition unit 212. Based on this received information, the control device 31 determines the control target value using the control target value determination unit 214. In this embodiment, the control target value determination unit 214 determines the control target value using the past history of the received information (information stored in the storage unit 213). The management device 31 then transmits information about the control target value to the equipment control device 13 via the information transmission unit 215.
[0082] The device control unit 13 receives information transmitted from the management device 31 via the information receiving unit 114. The device control unit 13 also receives and acquires information provided by the information providing unit 51 via the external information acquisition unit 112. Then, based on this received information, the device control device 13, with the device control unit 115, determines a value (control value) for controlling the device unit 12 and controls the device unit 12.
[0083] Thus, the equipment control device 13 has the function of controlling the equipment unit 12 according to the predicted values of the indoor living environment prediction simulation R1. The device control unit 13 has, for example, a function to optimize the control content of the device unit 12 (a function of the device optimization control engine), and a function to find the optimal solution for multidimensional control parameters.
[0084] In this embodiment, an algorithm for predicting changes in the residential thermal environment is used as the control logic for the residential environment prediction simulation. This algorithm may be, for example, an algorithm that uses linear regression. This algorithm may be constructed based on the characteristics of each indoor R1 to be controlled, or several patterns of indoor R1 may be set and the algorithm may be constructed based on the characteristics of each pattern. Furthermore, in this embodiment, a function is used to optimize the control mode of the equipment unit 12, which is energy-saving and optimizes the control of the equipment toward the target thermal environment. As an optimization of the control mode of multiple devices, optimization may be performed to adjust the trade-off relationship between the effects of these multiple devices.
[0085] [Overall control in equipment control systems] In this embodiment, the control functions of the control unit in the equipment control system 1 are distributed to an equipment control device 13 that acquires measured values (detected values of the detection unit 11) and controls the equipment unit 12 in the room R1, and a management device 31 that communicates with the equipment control device 13 to store and analyze various types of information. However, as an example of other configurations, the control functions of the control unit in the equipment control system 1 may be distributed to three or more devices, or they may be integrated into a single device. If the control function of the control unit in the equipment control system 1 is distributed across two or more devices, it is sufficient that the control function is realized as a whole, and the manner in which the control function is distributed is arbitrary.
[0086] If the functions of the management device 31 are integrated into the equipment control device 13, for example, communication between the management device 31 and the equipment control device 13 in this embodiment becomes unnecessary, and the information stored in both devices is stored in the equipment control device 13. Also, the functions of the external information acquisition unit 212 of the management device 31 become unnecessary because they are integrated into the external information acquisition unit 112 of the equipment control device 13. Furthermore, the functions of the control target value determination unit 214 of the management device 31 are integrated into the functions of the equipment control unit 115 of the equipment control device 13. In this case, the equipment control unit 115 of the equipment control device 13 has all the control functions in the equipment control system 1.
[0087] The control functions in the equipment control system 1 shown in this embodiment (a combination of the control functions in the management device 31 and the control functions in the equipment control device 13) are merely examples and are not limited to the control configuration of this embodiment. For example, various types of information may be used as information for acquiring measured values (detected values from the detection unit 11), reference information other than measured values, information for acquiring predicted values, information for determining control target values, and control values for controlling each device. Furthermore, various forms may be used for the parameters used for control, the methods for predicting each parameter, the methods for determining each control target value, and the methods for controlling each device. Furthermore, various forms may be used for the granularity of control or the unit of control. The unit of control may be one or more rooms in a building, or the entire building (whole building unit), or even a unit for each person.
[0088] As described above, in the equipment control system 1 according to this embodiment, the detection unit 11 detects one or more of the following for the room R1 to be controlled: humidity, brightness, sound level, odor component concentration, chemical substance concentration, amount of clothing worn by the user (in this embodiment, the amount of clothing worn by the resident), or the amount of exercise of the user (in this embodiment, the amount of exercise of the resident), as well as the room temperature and the outside temperature. Then, in the equipment control system 1 according to this embodiment, the control unit (in this embodiment, the control function of the equipment control device 13 and the control function of the management device 31) controls the equipment that affects the room temperature (in this embodiment, the equipment of the equipment unit 12) based on the detection results of the detection unit 11. Therefore, in the equipment control system 1 according to this embodiment, the equipment can be controlled in a controlled room R1 based on one or more of the following: humidity, brightness, sound level, odor component concentration, chemical substance concentration, amount of clothing worn (in this embodiment, the amount of clothing worn by the occupants), or amount of physical activity (in this embodiment, the amount of physical activity of the occupants) in order to make the indoor environment comfortable while suppressing power consumption.
[0089] Furthermore, in the equipment control system 1 according to this embodiment, the detection unit 11 further detects one or more of the following for the room R1 to be controlled: solar radiation gain, power consumption of equipment controlled by the control unit, power consumption of equipment not controlled by the control unit (uncontrolled equipment), indoor ventilation rate, whether or not a user (in this embodiment, an occupant) is present in room R1, the user's biometric information, or preferences specified by the user. Then, in the equipment control system 1 according to this embodiment, the control unit controls the equipment that affects the room temperature based on the detection results of the detection unit 11. Therefore, in the equipment control system 1 according to this embodiment, by controlling the equipment in the indoor room R1 to be controlled based on further information, it is possible to enhance the effect of making the indoor environment comfortable while suppressing power consumption.
[0090] Furthermore, the device control system 1 according to this embodiment includes an external information acquisition unit (in this embodiment, the external information acquisition unit 112 of the device control device 13 and the external information acquisition unit 212 of the management device 31) that acquires predetermined information provided from an external source. Then, in the device control system 1 according to this embodiment, the control unit controls the device based on the detection results from the detection unit 11 and the acquisition results from the external information acquisition unit. Therefore, in the equipment control system 1 according to this embodiment, by controlling the equipment based on the detection results of the detection unit 11 as well as weather information provided from an external source, it is possible to enhance the effect of making the indoor environment comfortable while suppressing power consumption.
[0091] Furthermore, in the device control system 1 according to this embodiment, the control unit controls the device based on the control state, along with the detection result from the detection unit 11 (or together with the detection result from the detection unit 11 and externally provided information). Therefore, in the equipment control system 1 according to this embodiment, by controlling the equipment based on the control state along with the detection result of the detection unit 11 (or together with the detection result of the detection unit 11 and externally provided information), it is possible to enhance the effect of making the indoor environment comfortable while suppressing power consumption.
[0092] Furthermore, in the equipment control system 1 according to this embodiment, the target value (also referred to as the control target value in this embodiment) is set by default to fall within a predetermined comfort standard range. Therefore, in the equipment control system 1 according to this embodiment, even if, for example, the resident or others do not perform the task of setting such a reference range, it is possible to enhance the effect of making the indoor environment comfortable while suppressing power consumption by using a general indicator or a unique indicator. Furthermore, the equipment control system 1 according to this embodiment has a function in the control unit to set (customize) a comfort range (a comfort range that is modified from the comfort reference range and used as a reference range within which the target value should fall) based on the user's preferences. Therefore, in the equipment control system 1 according to this embodiment, the effect of making the indoor environment comfortable while suppressing power consumption can be enhanced by using a comfort range based on the user's preferences.
[0093] Furthermore, the device control system 1 according to this embodiment has a control unit that has a function to set (customize) target values based on the user's preferences. Therefore, in the equipment control system 1 according to this embodiment, the effect of making the indoor environment comfortable while suppressing power consumption can be enhanced by setting target values based on user preferences. Furthermore, the device control system 1 may include either a function to set a comfort range based on the user's preferences or a function to set a target value based on the user's preferences, or it may be configured in a way that does not include either of these functions.
[0094] [Predicted values and control target values for the living environment] Figure 2 shows an example of the relationship between predicted values and control target values for the living environment according to the embodiment. In the graph shown in Figure 2, the horizontal axis represents time, and the vertical axis represents the room temperature R1. The graph shows three measured values (311, 312, and 313) and one predicted value (331) for room temperature. For example, in a living environment prediction simulation, a predicted value 331 for the future is calculated based on three past measured values 311, 312, and 313. Additionally, a target room temperature Q1 is set, and the difference 371 between the predicted value 331 and the target value Q1 is determined.
[0095] Here, any timing can be used to acquire the measured values; for example, every 30 minutes may be used. Furthermore, any timing can be used to acquire weather forecasts; for example, every 30 minutes or every hour may be used. Here, the timing of obtaining the measured values and the timing of obtaining the weather forecast may be the same, or they may be different.
[0096] In the example shown in Figure 2, room temperature is used as the physical quantity; however, other physical quantities may also be used. For example, in a living environment prediction simulation, information other than room temperature may be referenced. For example, in a residential environment prediction simulation, predictions may be made based on various information such as the history of room temperature, the history of outside temperature, the forecast of outside temperature (weather forecast), and the history of power consumption of specified equipment such as air conditioners. Furthermore, the control target value is not limited to temperature (in this case, room temperature), but may also be various other control target values such as humidity, illuminance, and power consumption.
[0097] [Specific examples of predicting living environments] Figure 3 shows a specific example of predicting the living environment according to this embodiment. In the graph shown in Figure 3, the horizontal axis represents time, the left vertical axis represents the power consumption [Wh] of the indoor air conditioner R1, and the right vertical axis represents temperature [°C]. The graph shows the temporal changes in the indoor room temperature (R1) (1101), the outside temperature (1102), the predicted room temperature (1103), and the AC power consumption (1121) by the air conditioner. In the example in Figure 3, the time progression from time t1 to time t6 is shown. Here, the values for room temperature (1101), outside temperature (1102), and predicted room temperature (1103) are determined by the vertical axis on the right. The value for power consumption (1121) is determined by the vertical axis on the left.
[0098] In the example in Figure 3, room temperature is used as a physical quantity, and the power consumption of an air conditioner was used as an example, but this is not the only example. For example, other physical quantities may be used as physical quantities. Furthermore, the power consumption of other devices may be used as the power consumption amount. For example, the power consumption of two or more devices (separate values for each device, or the sum of the values for these two or more devices) may be used.
[0099] [Example of a table] Refer to Figures 4 to 8 to illustrate examples of the use of various tables in the equipment control system 1. Figure 4 shows an example of an indoor environment measurement table 2011 according to the embodiment. In this embodiment, the measurement value table 2011 is stored in the storage unit 213. The measurement value table 2011 stores various measurement values (in this embodiment, the detected values of the detection unit 11) for one or more measurement points. In this embodiment, one or more measurement points are set in the room R1.
[0100] Figure 4 shows information for one measurement point. "No" represents the number of one measurement point set in room R1. "Room temperature" represents the temperature detection result at the measurement point. "Humidity" represents the detected humidity at the measurement point. "Illuminance" represents the detected illuminance at the measurement point. "Solar radiation gain" represents the detection result of solar radiation gain at the measurement point. "CO2 concentration" represents the detected CO2 concentration (carbon dioxide concentration) at the measurement point. "AC power" represents the detected AC power at the measurement point.
[0101] In the example in Figure 4, one or more measurement times (for example, year, month, day, and time) are entered in the Measurement Point No. column, and various detected values are entered for each measurement time. As a specific example, the measurement results for "2020 / 2 / 10 9:30" show room temperature "15.3℃", humidity "40%", illuminance "200lx", and solar radiation gain "100W / m²". 2 The following information is provided: CO2 concentration "500 ppm", AC power consumption "500 Wh".
[0102] Figure 5 shows an example of a predicted indoor environment table 2012 according to the embodiment. In this embodiment, the predicted value table 2012 is stored in the storage unit 213. The Prediction Value Table 2012 stores various predicted values for one or more measurement points. Figure 5 shows information for one measurement point.
[0103] In the example in Figure 5, one or more predicted times are entered in the Measurement Point No. column, and various predicted values are entered for each predicted time. As a specific example, the predicted results for "2020 / 2 / 10 9:30" are: room temperature "15.0℃", humidity "20%", illuminance "220lx", and solar radiation gain "120W / m²". 2 The CO2 concentration is listed as "350 ppm".
[0104] Figure 6 shows an example of a target value table 2013 for the indoor environment according to the embodiment. In this embodiment, the target value table 2013 is stored in the storage unit 213. The target value table 2013 stores various target values for one or more measurement points. Figure 6 shows information for one measurement point.
[0105] In the example in Figure 6, the "Measurement Point No." column contains a time value of 1 or more, and various target values are listed for each time value. Both lower and upper limits are set for these target values. As a specific example, the target values for "2020 / 2 / 10 9:30" are: lower limit of room temperature "20.0℃" and upper limit "25.0℃", lower limit of humidity "50%" and upper limit "60%", lower limit of illuminance "520lx" and upper limit "~(no upper limit)", and lower limit of solar radiation gain "320W / m 2 The document describes the upper limit "~(no upper limit)", the lower limit "400ppm", and the upper limit "800ppm" for CO2 concentration.
[0106] Figure 7 shows an example of a controlled device-measurement point table 2014 according to this embodiment. In this embodiment, the controlled device-measurement point table 2014 is stored in the storage unit 213. The Controlled Devices-Measurement Point Table 2014 identifies the controlled devices for one or more measurement points.
[0107] In the example shown in Figure 7, a number greater than or equal to 1 is entered in the Measurement Point No. column, and each number specifies the controlled device. As a specific example, for measurement point number "01-1," the controlled devices identified are blinds, shutters, screens, air conditioners, underfloor heating, ventilation fans, and lighting. Note that the symbols used to describe each controlled device are abbreviations for convenience.
[0108] Figure 8 shows an example of a controlled device-state table 2015 according to this embodiment. In this embodiment, the controlled device-state table 2015 is stored in the storage unit 213. The Controlled Devices-Status Table 2015 stores the status for each controlled device.
[0109] In the example in Figure 8, the state of the controlled device is described for each time period. As a specific example, the state for "2020 / 2 / 10 9:30" includes: blinds "0", shutters "0", screens "0", air conditioner "22-1-9", floor heating "2", ventilation fan "1", and lighting "0".
[0110] Here, for the blinds, "0" represents fully open, and "1" represents a blind angle of 45 degrees. Regarding the shutter, "0" represents the fully open state, and "1" represents the closed state. For the screen, "0" represents the fully open state, and "1" represents the closed state. Regarding the air conditioner, "22" indicates a set temperature of 22 degrees, "1" indicates a low fan speed, and "9" indicates automatic airflow direction. Regarding underfloor heating, "2" indicates full heating, "1" indicates half heating, and "0" indicates the system is off. For ventilation fans, "1" indicates the "on" state, and "0" indicates the "off" state. Regarding lighting, "1" represents the "on" state, and "0" represents the "off" state.
[0111] Here, any abbreviation may be used for each controlled device, and any number may be used to represent the possible states of the device.
[0112] The combinations of multiple physical quantities and multiple controlled devices shown in Figures 3 to 8 are merely examples and are not limited to these. For example, when a combination of multiple physical quantities is used, any number of different physical quantities may be used in combination. Furthermore, when multiple controlled devices are used, any number of different devices may be combined and used. Furthermore, any combination of one or more physical quantities and one or more controlled devices may be used.
[0113] [Example of a measurement, prediction, and control flow] Figure 9 shows an example of the relationship between measured values, predicted values, and controlled values according to the embodiment. The horizontal axis in Figure 9 represents time. In the example in Figure 9, times (t-1), t, and (t+1) are shown. These times are equally spaced. The same applies to times before (t-1) and times after (t+1).
[0114] The measured value X(i) represents the measurement taken at time i (=t-1, t, t+1). The measured value X(i) represents the actual temperature in the indoor environment R1. The predicted value Y(i) represents the predicted value at time i (=t-1, t, t+1). The predicted value Y(i) represents the predicted temperature according to the living environment prediction simulation algorithm. The control value Z(i) represents the control value at time i (=t-1, t, t+1). The control value Z(i) represents the control content by the algorithm of the equipment optimization control engine.
[0115] Referring to Figure 9, the time evolution of the control logic due to the flow from residential environment prediction simulation to equipment control will be explained. Here, we will explain the measured value X(t) at time i=t, but the same applies to other times.
[0116] Based on the measured value X(t) at time t, the predicted value (t+1) at time (t+1) is calculated using a living environment prediction simulation. Based on the predicted value (t+1) at time (t+1), the device optimization control engine controls the control value Z(t), which is the control content for time t. As a result, the measured value X(t+1) at time (t+1) changes depending on the control value Z(t) at time t.
[0117] In this demonstration experiment, the accuracy of the control is improved by collecting data that shows how much the measured value X(t+1) changes depending on the control value Z(t), in order to generate coefficients that depend on the individual environment (for example, the performance of the building structure or the surrounding environment).
[0118] In the example shown in Figure 9, temperature is used as the physical quantity, and an example of the relationship between the measured value, predicted value, and control settings is explained. However, other physical quantities may be used as the physical quantity. Furthermore, the measured value and predicted value may each be determined according to, for example, two or more different physical quantities.
[0119] Thus, in the device control system 1 according to this embodiment, the control unit determines the control content of the device according to a predetermined algorithm. The algorithm includes a measured value (detected value by the detection unit 11) related to a predetermined physical quantity, a predicted value related to the physical quantity, and the control content as parameters. Therefore, in the equipment control system 1 according to this embodiment, for example, by using such an algorithm to control the equipment, it is possible to enhance the effect of making the indoor environment comfortable while suppressing power consumption.
[0120] In this embodiment, the equipment control unit 115 of the equipment control device 13 may determine the control content of the equipment unit 12 so as to bring the predicted value closer to the target value for one or more predetermined physical quantities, and control the equipment unit 12 based on the determined control content. In this case, as shown in the example in Figure 1, for example, the control target value determination unit 214 of the management device 31 transmits information on the target value (control target value) and the predicted value for the predetermined physical quantity to the information receiving unit 114 of the equipment control device 13 via the information transmission unit 215. Based on the information received by the information receiving unit 114, the equipment control unit 115 of the equipment control device 13 controls the equipment unit 12 so that the predicted value approaches the target value.
[0121] Thus, in the equipment control system 1 according to this embodiment, the control unit controls the equipment to bring the predicted value closer to the target value. Therefore, in the equipment control system 1 according to this embodiment, by controlling the equipment to bring the predicted value of one or more predetermined physical quantities closer to the target value, it is possible to enhance the effect of making the indoor environment comfortable while suppressing power consumption.
[0122] [Examples of operation in equipment control systems] Figure 10 shows an example of the processing procedure performed in the equipment control system 1 according to this embodiment. In the example in Figure 10, for the sake of simplicity, indoor temperature, indoor illumination, electric blinds, and air conditioning are specifically used as examples, but the explanation is not limited to these.
[0123] (Step S1) The control device 31 acquires measurement data regarding the environment of the room R1. In this embodiment, the measurement data is the detected value of the detection unit 11 regarding the environment of the room R1. The management device 31 also acquires equipment operation logs.
[0124] (Step S2) The management device 31 acquires weather forecast data and actual measurement data. In this embodiment, the weather forecast data is weather forecast information provided by the information provision unit 51. In this embodiment, the actual measurement data is the detected value of the weather detection unit 11.
[0125] (Step S3) The control device 31 predicts changes in the indoor R1 environment based on measurement data related to the indoor R1 environment, equipment operation logs, weather forecast data, and actual measurement data.
[0126] (Step S4) The control device 31 obtains predicted values regarding the indoor environment R1 through prediction calculations. In this example, the control device 31 obtains a predicted value P1 for the temperature (room temperature) of room R1 and a predicted value P2 for the illuminance of room R1.
[0127] (Step S5) The control device 31 acquires the target value of the room temperature (room temperature) of room R1.
[0128] (Step S6) The control device 31 acquires the target value for the illuminance of room R1.
[0129] Here, each target value may be set as a fixed value, or as a variable value. For example, fixed target values may be set by residents or other relevant parties. As another example, the management device 31 may determine a variable target value each time based on predetermined information. This predetermined information may include the preferences of the residents. The management device 31 may also determine the target value using machine learning based on past data.
[0130] (Step S7) The control device 31 compares the predicted value with the target value. In this example, the control device 31 compares the predicted value with the target value for the temperature (room temperature) of room R1, and also compares the predicted value with the target value for the illuminance of room R1.
[0131] As a result, if the management device 31 determines that there is a difference of more than a predetermined threshold between the predicted value and the target value, it controls the equipment unit 12. In the example in Figure 1, the management device 31 transmits the control target value to the equipment control device 13, which then controls the equipment unit 12. The equipment control device 13 controls the equipment unit 12 based on the control target value from the management device 31. On the other hand, if the control device 31 does not determine that there is a difference of more than a predetermined threshold between the predicted value and the target value (i.e., the difference is less than the threshold), it returns to the initial processing of this flow (processing in step S1) without controlling the equipment unit 12. In this example, if there is a difference in at least one of the temperature and illuminance, the equipment unit 12 is controlled.
[0132] (Step S8) The equipment control device 13 controls the equipment unit 12. In this example, the device control unit 13 first operates the electric blinds that affect room R1.
[0133] (Step S9) The equipment control device 13 further controls the equipment unit 12. In this example, the equipment control device 13 performs operations on the air conditioner that affect the indoor R1.
[0134] (Step S10) The device control unit 13 stores the device operation log data. In the example shown in Figure 1, the device control unit 13 transmits the device operation log data to the management device 31, and the data is stored in the storage unit 213 of the management device 31. In this example, the equipment operation logs are the operation logs (details of operation) for the electric blinds and the operation logs (details of operation) for the air conditioner. Then, we return to the initial processing of this flow (processing in step S1).
[0135] In this example, the equipment control system 1 predicts the indoor temperature and illuminance that change over time, and adjusts the degree to which solar radiation is suppressed by the electric blinds, which are environmental control devices, thereby suppressing changes in the indoor environment. As a result, the indoor environment changes less, the number of times the air conditioner needs to be operated can be reduced, and overall, the power consumption by the air conditioner is reduced. Thus, the equipment control system 1 can operate appropriate environmental control equipment to suppress changes in the indoor environment and reduce power consumption.
[0136] In the example shown in Figure 10, indoor temperature, indoor illuminance, electric blinds, and air conditioner were specifically illustrated, but similar control methods may be applied to various physical quantities, various devices, etc.
[0137] [Regarding the above embodiments] As described above, the equipment control system 1 according to this embodiment makes it possible to control equipment in a way that makes the indoor environment comfortable while suppressing power consumption.
[0138] In the equipment control system 1 according to this embodiment, measured values related to the living environment are acquired, predicted values representing moment-to-moment changes in the living environment are acquired based on these measured values, and the equipment to be controlled is optimally controlled based on these predicted values. As a result, the equipment control system 1 according to this embodiment can optimize the control of residential equipment to achieve, for example, energy conservation and an environment desired by the residents, thereby achieving both low power consumption and the provision of a rich indoor environment. Information related to energy conservation may include, for example, information on power consumption, solar radiation gain, or ventilation rate.
[0139] In the equipment control system 1 according to this embodiment, for example, an active control system that optimizes the indoor environment for each individual residence using IoT (Internet of Things) technology makes it possible to respond to changes in lifestyle while making maximum use of the blessings of nature through passive design, in order to pursue energy conservation and comfort while at home, which are social demands. Furthermore, the equipment control system 1 according to this embodiment can control commonly installed equipment, thereby reducing installation costs. It also allows residents to choose whether or not to use the services of the equipment control system 1.
[0140] This section provides a concrete example of control using the equipment control system 1. Here, electric blinds and an air conditioner are used as examples of the controlled equipment. During the summer, the equipment control system 1 controls the electric blinds outside the window based on the sun's altitude and azimuth, weather forecasts, and predictions of whether or not residents are present. One control method for electric blinds is to prioritize blocking as much sunlight as possible to suppress the rise in room temperature and heat buildup. Another control method is to let in only the necessary and sufficient light, and use a small amount of air conditioning in conjunction to prevent the room from becoming too dark. The equipment control system 1 can selectively adopt the operation of these control methods. For example, depending on the occupant's preferences, the equipment control system 1 can control the amount of light entering the room to be sufficient when the occupant is present, and control the amount of sunlight blocked as much as possible when the occupant is absent (not present). As a result, the equipment control system 1 operates while taking into account the residents' preferences, aiming to maintain an optimal environment when residents are in their rooms, returning home, or going to sleep.
[0141] Furthermore, during the autumn season, the equipment control system 1 controls the skylight with electric blinds according to the sun's altitude and azimuth, as well as the weather forecast for that day, even when the residents are away. This control method involves adjusting and executing actions such as actively taking in sunlight, ventilating, and closing blinds at night to prevent cold air from entering. This allows the equipment control system 1 to maintain the room temperature at a predetermined level when residents return home, and to enable residents to spend their time without using (or with reduced usage of) heating or cooling.
[0142] Thus, in the equipment control system 1 according to this embodiment, when there are multiple devices (e.g., blinds, air conditioners, etc.) that can adjust the room temperature (e.g., raise the room temperature, lower the room temperature, or maintain the room temperature), the system controls one or more devices (e.g., blinds only, air conditioner only, or both) in such a way that the conditions of other living environments affected by each device (e.g., brightness in the case of blinds, etc.) are met. As a result, when adjusting the room temperature, the equipment control system 1 determines appropriate control settings as an overall control of multiple devices to satisfy other living environment conditions such as brightness, thereby providing residents with overall living environment comfort, including room temperature.
[0143] Here, the other living environment is not limited to brightness, but may be any living environment, and may be two or more living environments. Specifically, other living environment factors may include humidity, brightness, sound level, odor component concentration, chemical substance concentration, solar radiation gain, power consumption of all or specific equipment, or indoor R1 ventilation rate. For example, since different equipment may have different effects on these living environment factors, it is preferable to consider these other living environment factors along with room temperature when deciding which equipment to control, when, and how. Furthermore, since the comfort of the living environment also depends on the condition of the residents, it is preferable to consider factors such as the amount of clothing the residents are wearing, their activity level, whether or not residents are in room R1, the residents' biometric information, and the residents' preferences when deciding which devices to control, when, and how.
[0144] Furthermore, a program to realize the function of any component in any of the devices described above may be recorded on a computer-readable recording medium, and that program may be loaded into a computer system and executed. Here, "computer system" includes hardware such as an operating system (OS) or peripheral devices. "Computer-readable recording medium" refers to portable media such as flexible disks, magneto-optical disks, ROMs, CD (Compact Disc)-ROMs, and storage devices such as hard disks built into computer systems. Moreover, "computer-readable recording medium" also includes volatile memory (RAM) inside computer systems that act as servers or clients when a program is transmitted via a network such as the Internet or a communication line such as a telephone line, which retains the program for a certain period of time.
[0145] Furthermore, the above program may be transmitted from a computer system that stores the program in a memory device or the like to another computer system via a transmission medium or by transmission waves within the transmission medium. Here, the "transmission medium" used to transmit the program refers to a medium that has the function of transmitting information, such as a network like the Internet or a communication line like a telephone line. Furthermore, the above program may be intended to implement only a portion of the functions described above. Moreover, the above program may be a so-called differential file, capable of implementing the aforementioned functions in combination with programs already recorded in the computer system. A differential file may also be called a differential program.
[0146] The functions of any component in any device described above may be implemented by a processor. For example, each process in the embodiment may be implemented by a processor that operates based on information such as a program, and a computer-readable recording medium that stores information such as a program. Here, the processor may be implemented by having the functions of each part implemented by separate hardware, or by having the functions of each part implemented by integrated hardware. For example, the processor includes hardware, and the hardware may include at least one of a circuit that processes digital signals and a circuit that processes analog signals. For example, the processor may be configured using one or more circuit devices or one or both of one or more circuit elements mounted on a circuit board. An IC (Integrated Circuit) may be used as the circuit device, and a resistor or capacitor may be used as the circuit element.
[0147] Here, the processor may be, for example, a CPU. However, the processor is not limited to a CPU; various types of processors may be used, such as a GPU (Graphics Processing Unit) or a DSP (Digital Signal Processor). The processor may also be, for example, a hardware circuit using an ASIC (Application Specific Integrated Circuit). Furthermore, the processor may be composed of, for example, multiple CPUs, or multiple hardware circuits using ASICs. The processor may also be composed of, for example, a combination of multiple CPUs and multiple hardware circuits using ASICs. The processor may also include, for example, one or more amplifier circuits or filter circuits that process analog signals.
[0148] While embodiments of this invention have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments and includes designs and the like that do not depart from the spirit of this invention. [Explanation of symbols]
