Description

[Technical field]

[0001] The present disclosure relates to buildings and control systems. [Background technology]

[0002] In a building, a system is known that controls devices arranged in a room depending on the presence or absence of a person in the room. Patent Document 1 discloses a device control system that stops the operation of load devices in a room when a human presence sensor detects no human in the room. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2010-205673 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, there are cases where it is preferable not to stop the operation of a device even when no one is in the room. For example, if a device is stopped when a person temporarily leaves the room, the device needs to be started again when the person returns to the room, which may be annoying for the person. [Means for solving the problem]

[0005] (1) A building that solves the above problem is a building having a control system that controls equipment placed in a room, the control system comprising a human presence sensor configured to detect people in the room, and a control device, the control device having an indoor state determination unit configured to determine an indoor activity state indicating the presence or absence and activity of the person in the room based on detection information detected by the human presence sensor, and an equipment control unit configured to switch the operating state of the equipment between an operating state and a stopped state based on the indoor activity state, the indoor activity state including an entry state in which the person moves into the room from outside the room, an activity state in which the person is active within the room, a resting state in which the person is resting in the room, an exit state in which the person moves from inside the room to outside the room, and an absent state in which the person is outside the room.

[0006] According to this configuration, the indoor activity state includes a plurality of states related to the presence or absence of people in the room and their activities, so that the control device can finely control the appliances based on the people's activities.

[0007] (2) In the building described in (1) above, the control system further includes a lock sensor configured to detect locking information of the front door, the indoor state determination unit is configured to determine the presence or absence of a person in the building based on the locking information, and the equipment control unit is configured to switch the operation state of the equipment between an operating state and a stopped state based on the indoor behavior state and the presence or absence of the person in the building.

[0008] According to this configuration, the indoor state determination unit can more accurately determine the presence or absence of a person in the room based on the presence or absence of a person in the building, which allows the control device to more precisely control the device based on the behavior of the person.

[0009] (3) In the building described in (1) or (2) above, the equipment includes a first equipment and a second equipment whose starting and stopping of operation has a greater impact on the people than the first equipment, and the equipment control unit is configured to control the first equipment and the second equipment so that an operating state of the first equipment differs from an operating state of the second equipment in at least one of the indoor behavior states.

[0010] According to this configuration, the first appliance and the second appliance can be controlled in different modes. For example, the first appliance and the second appliance can be controlled so that they start or stop operating at different times. In addition, the first appliance and the second appliance, which have different functions, can be operated in a detailed manner based on the presence or absence of people in the room and their actions.

[0011] (4) In the building described in (3) above, the equipment control unit is configured to set the operating state of the first equipment to a stopped state and the operating state of the second equipment to an operating state based on the indoor state determination unit determining that the indoor behavior state is the resting state.

[0012] According to this configuration, the first device is in a stopped state when a person is resting in the room, so that the power consumption of the first device can be reduced.

[0013] (5) In the building described in (3) or (4) above, the equipment control unit is configured to set the operation state of the first equipment to a stopped state and the operation state of the second equipment to an operating state based on a determination by the indoor state determination unit that the indoor behavior state is the left-behind state, and to maintain the operation state of the first equipment to a stopped state and set the operation state of the second equipment to a stopped state based on a determination by the indoor state determination unit that the indoor behavior state has changed from the left-behind state to the absent state.

[0014] According to this configuration, the second device is maintained in an operating state even if a person moves from inside the room to outside the room, so there is no need to switch the operation state of the second device from a stopped state to an operating state when the person returns to the room from outside the room. This makes it possible to suppress the impact on people caused by the second device being stopped. In addition, when the indoor behavior state changes from a left state to an absent state, such as when a person moves from inside the room to outside the room and does not return to the room, the second device is stopped, so it is possible to suppress an increase in power consumption of the second device.

[0015] (6) In the building described in any one of (1) to (5) above, the control system further includes an environmental sensor configured to detect environmental information in the room, the indoor state determination unit is configured to determine the environmental state of the room from the environmental information, and the equipment control unit is configured to suspend switching of the operation state of the equipment based on the indoor activity state when the environmental state satisfies a predetermined environmental condition.

[0016] According to this configuration, when the environmental state satisfies a predetermined environmental condition, switching of the operation state of the device is suspended, so that an increase in power consumption of the device can be suppressed.

[0017] (7) A control system that solves the above problem is a control system that controls equipment placed in a room of a building, and includes a human presence sensor configured to detect a person in the room, and a control device. The control device has an indoor state determination unit configured to determine an indoor activity state indicating the presence or absence and activity of the person in the room based on detection information detected by the human presence sensor, and an equipment control unit configured to switch the operating state of the equipment between an operating state and a stopped state based on the indoor activity state, and the indoor activity state includes an entry state in which the person moves into the room from outside the room, an activity state in which the person is active in the room, a resting state in which the person is resting in the room, an exit state in which the person moves from inside the room to outside the room, and an absent state in which the person is outside the room.

[0018] According to this configuration, the indoor activity state includes a plurality of states related to the presence or absence of people in the room and their activities, so that the control device can finely control the appliances based on the people's activities. Effect of the Invention

[0019] The building and control system disclosed herein can precisely control equipment based on the presence and behavior of people in a room. [Brief description of the drawings]

[0021] <Embodiment> A building 10 and a control system 20 according to this embodiment will be described with reference to FIGS.

[0022] <Buildings> As shown in Fig. 1, the building 10 of this embodiment is a detached house. Fig. 1 illustrates a one-story detached house, but the detached house may have two or more floors. The building 10 may be a residential facility such as an apartment building, a lodging facility, a medical facility, or a nursing home. The building 10 may be a commercial facility such as a shopping mall, an office building, or an indoor amusement park.

[0023] The building 10 includes rooms 11. The rooms 11 include a first room 11a, a second room 11b, a third room 11c, a fourth room 11d, and a fifth room 11e. For example, the first room 11a is a living room, the second room 11b is a kitchen, the third room 11c is a private room, the fourth room 11d is a dressing room, and the fifth room 11e is a bathroom. The building 10 includes an entrance 12. The entrance 12 is connected to each of the first room 11a, the second room 11b, the third room 11c, the fourth room 11d, and the fifth room 11e via a corridor 13.

[0024] The room 11 is provided with devices 14. The devices 14 are devices that change the environment of the room 11, such as brightness, temperature, room temperature, odor, and sound. The devices 14 are configured to be able to communicate with the control system 20 via a communication network such as the Internet. The devices 14 include a first device 14a and a second device 14b. FIG. 1 illustrates an example in which the device 14 is provided in the first room 11a, but the devices 14 may be provided in each of the first room 11a, the second room 11b, the third room 11c, the fourth room 11d, and the fifth room 11e.

[0025] The second device 14b has a larger impact on people when it starts and stops operating than the first device 14a. The impact on people when it starts and stops operating is, for example, the time it takes for the device 14 to change the environment of the room 11. The first device 14a is, for example, a light or an audio speaker. The second device 14b is, for example, an air conditioner, a ventilation device, or a heating device. The air conditioner is, for example, a device that performs cooling or heating. The air conditioner may be a device such as a humidifier, an air purifier, or a diffuser. The ventilation device is, for example, a ventilation fan. The heating device is, for example, an electric heater or a gas fan heater.

[0026] The second device 14b may be an automatic water faucet or a cooking heater. An automatic water faucet is, for example, a device in which the main valve of the faucet is electrically operated. With an automatic water faucet, for example, when a person goes out, the main valve is closed, thereby preventing water from being left running. An example of a cooking heater is a gas stove or an electric stove.

[0027] In the following, the first room 11a will be described as an example of the room 11. Both the first device 14a and the second device 14b are provided in the first room 11a. The first device 14a in the first room 11a is a light, and the second device 14b in the first room 11a is an air conditioner.

[0028] <Control system> As shown in FIG. 1 and FIG. 2, the building 10 has a control system 20. The control system 20 constitutes a Home Energy Management System (HEMS). Devices 14 are connected to the HEMS. The control system 20 controls the devices 14 arranged in a room 11 of the building 10. The control system 20 controls the devices 14 based on the presence or absence and behavior of a person in the room 11. The person is a person who uses the room 11. The person may be a person who is temporarily staying in the building 10 or a person who is temporarily using the building 10.

[0029] The control system 20 includes a human presence sensor 21 and a control device 30. The control system 20 further includes a lock sensor 22. The control system 20 further includes an environmental sensor 23. The human presence sensor 21, the lock sensor 22, and the environmental sensor 23 are communicatively connected to the control device 30 by wire or wirelessly. The human presence sensor 21, the lock sensor 22, and the environmental sensor 23 may be connected to the control device 30 via a communication network such as a wireless LAN or the Internet.

[0030] The control system 20 may include a plurality of human presence sensors 21. Each of the plurality of human presence sensors 21 may be provided in the first room 11a, the second room 11b, the third room 11c, the fourth room 11d, and the fifth room 11e. The control system 20 may include a plurality of environmental sensors 23. Each of the plurality of environmental sensors 23 may be provided in the first room 11a, the second room 11b, the third room 11c, the fourth room 11d, and the fifth room 11e.

[0031] <Sensor> The human presence sensor 21 is configured to detect a person in the room 11. The human presence sensor 21 is, for example, a pyroelectric sensor. The pyroelectric sensor detects a person in the room 11 by detecting the movement of the person in the room 11. The human presence sensor 21 is attached to a ceiling or a wall surface of the room 11. When the human presence sensor 21 detects a person in the room 11, it outputs detection information indicating that a person has been detected in the room 11 to the control device 30.

[0032] The locking sensor 22 is configured to detect locking information of the entrance 12. The locking information is, for example, information regarding the locking of the key at the entrance 12. The locking information includes, for example, that the entrance 12 has been locked from outside the building 10. The locking information may further include at least one of that the entrance 12 has been locked from inside the building 10, that the entrance 12 has been unlocked from outside the building 10, and that the entrance 12 has been unlocked from inside the building 10. When the locking sensor 22 detects the locking information of the entrance 12, it transmits the locking information to the control device 30. When the locking sensor 22 of this embodiment is locked from outside the building 10, it outputs the locking information to the control device 30.

[0033] The environmental sensor 23 is configured to detect environmental information in the room 11. The environmental sensor 23 transmits the environmental information detected in the room 11 to the control device 30. The environmental state in this embodiment includes the temperature of the room 11. The environmental sensor 23 in this embodiment includes a temperature sensor. The temperature sensor is configured to detect the temperature of the room 11. In this embodiment, when the environmental sensor 23 detects the temperature of the room 11, it outputs a signal related to the temperature of the room 11 to the control device 30.

[0034] <Control device> The control device 30 is, for example, a computer including a CPU (Central Processing Unit), a memory, a display, a communication circuit, and an input device. The control device 30 is configured as, for example, a home server. The control device 30 of this embodiment is disposed in the second room 11b. The control device 30 may be disposed in another room 11. In this embodiment, the control device 30 is disposed in the building 10, but the control device 30 may be configured by an external server such as a cloud server. The control device 30 may be mounted on one of the devices 14. The control device 30 may be configured to be capable of data communication with a terminal device outside the building 10 via a communication network such as the Internet. The control device 30 controls the devices 14 by executing a control program.

[0035] The control device 30 has an indoor condition determination unit 31 and an equipment control unit 32. The indoor condition determination unit 31 and the equipment control unit 32 include one or more CPUs or one or more MPUs (Micro Processing Units) that operate according to a program. The indoor condition determination unit 31 and the equipment control unit 32 may be configured as a circuit including a CPU or MPU, a circuit including an application specific integrated circuit (ASIC), or a combination of these circuits. The indoor condition determination unit 31 and the equipment control unit 32 may include memories such as a RAM (Random Access Memory) and a ROM (Read Only Memory). The memory stores a program configured to cause the CPU to execute processing.

[0036] The control device 30 may further include a room information storage unit 33 and a device information storage unit 34. The room information storage unit 33 and the device information storage unit 34 are configured by semiconductor memories such as RAM and ROM, a hard disk, a magnetic tape, or an optical disk.

[0037] <Indoor condition determination section> 2, the indoor state determination unit 31 is configured to determine an indoor activity state based on detection information detected by the human presence sensor 21. The detection information is output from the human presence sensor 21 to the control device 30. The indoor state determination unit 31 determines the presence or absence and activity of a person in the room 11 based on the detection information. The indoor state determination unit 31 may be configured to determine whether a person has entered or left the room 11 based on the detection information by arranging the human presence sensor 21 at an entrance or exit of the room 11.

[0038] The indoor activity state is a state indicating the presence or absence and behavior of a person in room 11. The indoor activity state includes an entry state, an active state, a resting state, an exit state, and an absent state. The entry state is a state in which a person moves from outside room 11 into room 11. The active state is a state in which a person is active in room 11. The resting state is a state in which a person is resting in room 11. The exit state is a state in which a person moves from inside room 11 to outside the room. The absent state is a state in which a person is outside room 11.

[0039] The indoor state determination unit 31 is configured to be able to determine, for example, whether a person is in the room 11 or outside the room 11. When detection information is output from the human presence sensor 21 in the room 11 to the control device 30, the indoor state determination unit 31 determines that a person is in the room 11. When detection information is output from a human presence sensor 21 provided in a location different from the room 11 in a state in which detection information is not output from the human presence sensor 21 in the room 11, the indoor state determination unit 31 determines that a person is outside the room 11. For example, after determining that a person is in the room 11, the indoor state determination unit 31 may determine that a person has moved from inside the room 11 to outside the room 11 when the human presence sensor 21 arranged at the entrance of the room 11 detects a person. For example, after determining that a person is outside the room 11, the indoor state determination unit 31 may determine that a person has moved from outside the room 11 to inside the room 11 when the human presence sensor 21 arranged at the entrance of the room 11 detects a person.

[0040] The following describes the determination of the indoor activity state by the indoor state determination unit 31. The indoor state determination unit 31 determines the indoor activity state based on the detection or non-detection of a person in the room 11. When a person is detected in the room 11, the human presence sensor 21 in the room 11 is in a state where it outputs detection information. When a person is not detected in the room 11, the human presence sensor 21 in the room 11 is in a state where it does not output detection information.

[0041] When a person is detected in the room 11 in a case where the indoor activity state is an unoccupied state, the indoor state determination unit 31 determines that the indoor activity state has changed from an unoccupied state to an entered state.

[0042] When the indoor activity state is the absent state, if the human presence sensor 21 detects a person when a first period T1 has elapsed since the human presence sensor 21 detected a person in the room 11, the indoor state determination unit 31 determines that the indoor activity state is the active state. When a person is detected in the room 11, the indoor state determination unit 31 determines that the indoor activity state is the active state.

[0043] When the period during which no person is detected in the room 11 continues for a second period T2 and the indoor state determination unit 31 determines that a person is present in the room 11, the indoor state determination unit 31 determines that the indoor activity state is a resting state. Note that the determination that a person is present in the room 11 when determining that the indoor activity state is a resting state is made based on the determination that a person is not present outside the room 11.

[0044] When the period during which no person is detected in the room 11 continues for a second period T2 and the indoor state determiner 31 determines that a person is outside the room 11, it determines that the indoor activity state is a leaving state.

[0045] When the indoor state determination unit 31 determines that the indoor behavior state is a leaving state, and then a period of non-detection of a person in the room 11 continues for a third period T3, and determines that a person is outside the room 11, it determines that the indoor behavior state is a not-in-the-room state.

[0046] When the indoor activity state is the resting state, the indoor state determination unit 31 may determine that the indoor activity state is the active state if a person is detected in the room 11. When the indoor activity state is the leaving state, the indoor state determination unit 31 may determine that the indoor activity state is the active state if a person is detected in the room 11.

[0047] The indoor state determination unit 31 may determine the indoor activity state not only in the predetermined room 11 but also in each of the first room 11a, the second room 11b, the third room 11c, the fourth room 11d, and the fifth room 11e. The indoor state determination unit 31 stores the indoor activity state of each room in the room information storage unit 33.

[0048] The indoor state determination unit 31 is configured to determine whether or not a person is present in the building 10 based on the locking information. The locking information is output from the locking sensor 22 to the control device 30. For example, when locking information that the entrance 12 has been locked from outside the building 10 is output from the locking sensor 22 to the control device 30, the indoor state determination unit 31 determines that no person is present in the building 10. Preferably, the indoor state determination unit 31 determines that no person is present in the building 10 when, for example, a period in which the human sensor 21 does not detect a person in the building 10 continues for a fourth period T4 after the entrance 12 has been locked from outside the building 10. For example, when there is only one person using the building 10, the indoor state determination unit 31 may determine that no person is present in the building 10 when the entrance 12 is locked from outside the building 10. When the indoor state determination unit 31 determines that no person is present in the building 10, the indoor state determination unit 31 may determine that the indoor behavior state of the room 11 is an absent state.

[0049] The indoor state determination unit 31 is configured to determine the environmental state of the room 11 from the environmental information. The environmental information is output from the environmental sensor 23 to the control device 30. In this embodiment, the indoor state determination unit 31 determines the temperature of the room 11 from the temperature detected by the temperature sensor. The indoor state determination unit 31 may determine the environmental state not only in the predetermined room 11, but also in each of the first room 11a, the second room 11b, the third room 11c, the fourth room 11d, and the fifth room 11e. The indoor state determination unit 31 stores the environmental state of each room in the room information storage unit 33.

[0050] <Room information storage unit> As shown in FIG. 2 and FIG. 3, the room information storage unit 33 is configured to store room information related to the room 11. The room information storage unit 33 may be configured to store room information related to each of the first room 11a, the second room 11b, the third room 11c, the fourth room 11d, and the fifth room 11e. FIG. 3 shows an example of room information stored in the room information storage unit 33. The room information includes a room type, an indoor behavior state, and an environmental state for each room identification information. The room type is the purpose of each room, such as a living room, a kitchen, a private room, a dressing room, and a bathroom. The indoor behavior state is a state determined by the indoor state determination unit 31. The environmental state is a state determined by the indoor state determination unit 31 in each room. In this embodiment, the temperature of each room is stored as the environmental state.

[0051] <Device information storage section> As shown in FIG. 2 and FIG. 4, the device information storage unit 34 is configured to store device information related to the device 14. The device information storage unit 34 may be configured to store device information related to all devices 14 arranged in the building 10. FIG. 4 shows an example of device information stored in the device information storage unit 34. The device information includes, for each device identification number, a device type, an identification number of the room in which the device is arranged, an operating state, and a predetermined environmental condition. The device type is the type of each device. The identification number of the room in which the device is arranged is the identification number of the room 11 in which the device is arranged. The operating state is the current operating state of the device 14 that is switched by the device control unit 32. The predetermined environmental condition is a condition set for each device in order for the device control unit 32 to control the device 14.

[0052] <Device control section> 2, the appliance control unit 32 is configured to control the appliance 14. The appliance control unit 32 is configured to switch the operation state of the appliance 14 between an operating state and a stopped state based on the indoor activity state. The operating state is a state in which the appliance 14 operates. The stopped state is a state in which the appliance 14 stops operating.

[0053] The device control unit 32 is configured to control the first device 14a and the second device 14b so that the operation state of the first device 14a and the operation state of the second device 14b are the same operation state in at least one state of the indoor activity states. The device control unit 32 is configured to control the first device 14a and the second device 14b so that the operation state of the first device 14a and the operation state of the second device 14b are different in at least one state of the indoor activity states. For example, when the indoor state determination unit 31 determines that the indoor activity state is an entry state, a rest state, or an exit state, the device control unit 32 is configured to make the operation state of the first device 14a and the operation state of the second device 14b different.

[0054] The device control unit 32 is configured to set the operation state of the first device 14a to an operating state and the operation state of the second device 14b to a stopped state based on the indoor state determination unit 31 determining that the indoor behavior state is an entry state.

[0055] The device control unit 32 is configured to set the operating state of the first device 14a to an operating state and the operating state of the second device 14b to an operating state based on the indoor state determination unit 31 determining that the indoor activity state is an active state.

[0056] The device control unit 32 is configured to set the operation state of the first device 14a to a stopped state and the operation state of the second device 14b to an operating state based on the indoor state determination unit 31 determining that the indoor activity state is a resting state.

[0057] The device control unit 32 is configured to set the operation state of the first device 14a to a stopped state and the operation state of the second device 14b to an operating state based on the indoor state determination unit 31 determining that the indoor behavior state is an exit state.

[0058] The device control unit 32 is configured to stop the operation state of the first device 14a and stop the operation state of the second device 14b based on the indoor state determination unit 31 determining that the indoor activity state is an occupancy state.

[0059] The switching of the operation state of the device 14 by the device control unit 32 based on the indoor activity state will be described. The device control unit 32 sets the operation state of the first device 14a to the stopped state and the operation state of the second device 14b to the stopped state based on the indoor state determination unit 31 determining that the indoor activity state is the unoccupied state. When the indoor activity state is the unoccupied state and detection information is output from the human presence sensor 21 in the room 11 to the control device 30, the indoor state determination unit 31 determines that the indoor activity state is the entered state. Based on the indoor state determination unit 31 determining that the indoor activity state has changed from the unoccupied state to the entered state, the device control unit 32 sets the operation state of the first device 14a to the running state and maintains the operation state of the second device 14b in the stopped state.

[0060] Based on the indoor state determination unit 31 determining that the indoor behavior state has changed from the entry state to the activity state, the device control unit 32 maintains the operating state of the first device 14a in the operating state and sets the operating state of the second device 14b to the operating state.

[0061] The device control unit 32 sets the operation state of the first device 14a to a stopped state and maintains the operation state of the second device 14b in an operating state based on the indoor state determination unit 31 determining that the indoor activity state has changed from an active state to a resting state. The device control unit 32 may set the operation state of the first device 14a to an operating state and maintain the operation state of the second device 14b in an operating state based on the indoor state determination unit 31 determining that the indoor activity state has changed from a resting state to an active state.

[0062] The device control unit 32 sets the operation state of the first device 14a to a stopped state and maintains the operation state of the second device 14b in an operating state based on the indoor state determination unit 31 determining that the indoor activity state has changed from an active state to an exiting state. The device control unit 32 may set the operation state of the first device 14a to an operating state and maintain the operation state of the second device 14b in an operating state based on the indoor state determination unit 31 determining that the indoor activity state has changed from an exiting state to an active state.

[0063] The device control unit 32 is configured to maintain the operation state of the first device 14a in the stopped state and to stop the operation state of the second device 14b based on the indoor state determination unit 31 determining that the indoor behavior state has changed from the leaving state to the absent state. After the operation state of the first device 14a is stopped and the operation state of the second device 14b is stopped, when detection information is output from the human presence sensor 21 in the room 11 to the control device 30, the indoor state determination unit 31 determines that the indoor behavior state is the entering state.

[0064] The device control unit 32 may control the devices 14 as follows, based on the presence or absence of people in the building 10. The device control unit 32 is configured to switch the operation state of the devices 14 between an operating state and a stopped state, based on the indoor activity state and the presence or absence of people in the building 10. The device control unit 32 is configured to set the operation state of the first device 14a to a stopped state and the operation state of the second device 14b to a stopped state, regardless of the indoor activity state, based on the indoor activity state determination unit 31 determining that no people are present in the building 10.

[0065] The appliance control unit 32 may control the appliance 14 based on the environmental state of the room 11 as follows. The appliance control unit 32 is configured to suspend switching of the operation state of the appliance 14 based on the indoor activity state when the environmental state satisfies a predetermined environmental condition. The predetermined environmental condition in this embodiment includes a condition related to the temperature of the room 11. When switching the operation state of the air conditioner, which is the appliance 14, from a stopped state to an operating state based on the indoor activity state, the appliance control unit 32 suspends switching of the operation state of the heating appliance if the temperature of the room 11 is appropriate. When switching the operation state of the air conditioner, which is the appliance 14, from a stopped state to an operating state based on the indoor activity state, the appliance control unit 32 executes switching of the operation state of the second appliance 14b if the temperature of the room 11 is not appropriate.

[0066] The device control unit 32 determines that the temperature of the room 11 is appropriate when the difference between the temperature of the room 11 and the predetermined temperature is within a predetermined threshold. The predetermined temperature is set to, for example, 28 degrees in summer and 20 degrees in winter. The predetermined threshold is set to, for example, 3 degrees. The predetermined temperature and the predetermined threshold can be changed as appropriate depending on the type of room, the season, etc.

[0067] Fig. 5 shows a process related to the control of the device 14 by the device control unit 32. The process shown in Fig. 5 is executed at predetermined time intervals.

[0068] In step S11, the device control unit 32 acquires the indoor activity state of the room 11, and proceeds to step S12. The device control unit 32 acquires the indoor activity state of the room 11 from the room information storage unit 33, for example.

[0069] In step S12, the device control unit 32 determines whether or not to switch the operation state of the device 14. For example, when the operation state of the device 14 does not correspond to the operation state of the device 14 based on the indoor activity state of the room 11, the device control unit 32 determines to switch the operation state of the device 14. When the operation state of the device 14 is to be switched, the device control unit 32 proceeds to step S13.

[0070] In step S13, the device control unit 32 determines whether the environmental state of the room 11 satisfies a predetermined environmental condition. The device control unit 32 acquires the environmental state of the room 11 from, for example, the room information storage unit 33. The device control unit 32 acquires the predetermined environmental condition of the device 14 from, for example, the device information storage unit 34. If the environmental state of the room 11 satisfies the predetermined environmental condition, the device control unit 32 ends the processing of FIG. 5 without switching the operation state of the device 14. If the environmental state of the room 11 does not satisfy the predetermined environmental condition, the device control unit 32 proceeds to step S14. In step S14, the device control unit 32 switches the operation state of the device 14 based on the indoor activity state.

[0071] The operation of the device 14 in the room 11 by the control system 20 will be described with reference to Figures 6 and 7. In Figures 6 and 7, (a) motion sensor detection indicates a state in which the motion sensor 21 detects human movement in the room 11. (a) motion sensor non-detection indicates a state in which the motion sensor 21 does not detect human movement in the room 11. (b) lock sensor detection indicates a state in which the lock sensor 22 detects locking from outside the front door 12. (b) lock sensor non-detection indicates a state in which the lock sensor 22 does not detect locking from outside the front door 12. (c) The operating state and stop state of the first device indicate the operating state of the first device 14a. (d) The operating state and stop state of the second device indicate the operating state of the second device 14b.

[0072] 6 shows a first example of the operation of the device 14 by the control system 20 in the room 11. At time t10, the indoor state determiner 31 determines that the indoor activity state of the room 11 is an absent state.

[0073] Time t11 is the time when the human presence sensor 21 detects a person in the room 11. At time t11, the indoor state determination unit 31 determines that the indoor activity state of the room 11 has changed from an absent state to an entered state. At time t11, the device control unit 32 switches the operation state of the first device 14a from a stopped state to an operating state.

[0074] Time t12 is the time when the first period T1 has elapsed since time t11. At time t12, the indoor state determination unit 31 determines that the indoor activity state of the room 11 has changed from the entry state to the activity state. At time t12, the device control unit 32 switches the operation state of the second device 14b to the operating state.

[0075] Time t13 is the time when the human presence sensor 21 stops detecting a human in the room 11. In other words, time t13 is the time when the human presence sensor 21 stops detecting human movement in the room 11.

[0076] Time t14 is the time when the second period T2 has elapsed since time t13 without the human presence sensor 21 detecting anything. If the indoor state determination unit 31 determines that no person is present in the room 11 at time t14, it determines that the indoor behavior state of the room 11 has changed from an active state to a leaving state. If the indoor state determination unit 31 determines that a person is present in the room 11 at time t14, it determines that the indoor behavior state of the room 11 has changed from an active state to a resting state. At time t14, the device control unit 32 switches the operation state of the first device 14a to a stopped state.

[0077] Time t15 is the time when the third period T3 has elapsed since time t14 while the human presence sensor 21 remains in non-detection. When the indoor state determination unit 31 determines that there is no person in the room 11 at time t15, it determines that the indoor activity state of the room 11 has changed to an absent state. At time t15, the device control unit 32 switches the operation state of the first device 14a to a stopped state. The indoor state determination unit 31 may determine that there is no person in the room 11 because the human presence sensor 21 has not detected a person in the room 11 at time t15.

[0078] Fig. 7 shows a second example of the operation of the device 14 by the control system 20 in the room 11. The states of the human sensor 21, the first device 14a, and the second device 14b in Fig. 7 are the same as those in Fig. 7. Time t20 to time t23 corresponds to time t10 to time t13 in Fig. 7, and therefore a duplicated description will be omitted.

[0079] Time t24 is the time when the lock sensor 22 detects that the front door 12 has been locked from the outside.

[0080] Time t25 is the time when the fourth period T4 has elapsed since time t24 while the human presence sensor 21 of the building 10 remains non-detected. At time t25, the indoor state determination unit 31 determines that no one is present in the building 10. At time t25, the device control unit 32 switches the operation state of the first device 14a to a stopped state. At time t25, the device control unit 32 switches the operation state of the second device 14b to a stopped state. At time t24, the indoor state determination unit 31 may determine that no one is present in the building 10 without waiting for the passage of the fourth period T4.

[0081] The first period T1, the second period T2, the third period T3, and the fourth period T4 are configured to be changeable. For example, by setting the first period T1 to a short period, the period until the indoor state determination unit 31 determines that the indoor behavior state has changed from the entry state to the active state is shortened. For example, by setting the second period T2 to a short period, the period until the indoor state determination unit 31 determines that the indoor behavior state has changed from the active state to the resting state or the leaving state is shortened. For example, by setting the third period T3 to a long period, the period until the indoor state determination unit 31 determines that the indoor behavior state has changed from the leaving state to the absent state is lengthened. For example, by setting the fourth period T4 to a short period, the determination until the indoor state determination unit 31 determines that no person is present in the building 10 is quickened.

[0082] <Operation of the embodiment> A first effect of this embodiment will be described. If the device 14 continues to operate when no one is present in the room 11, there is a risk of unnecessary power consumption. Such forgetting to turn off the device 14 occurs when a person leaves the room 11, for example. In the building 10, the control system 20 switches the operation state of the device 14 to a stopped state when the indoor activity state is an unoccupied state. Therefore, even if the device 14 is forgotten to be turned off, the control system 20 suppresses an increase in unnecessary power consumption.

[0083] A second effect of this embodiment will be described. On the other hand, when a person returns to the room 11 immediately after leaving the room 11, the device 14 may be left on. In such a case, if the operation state of the device 14 is switched to a stopped state, the person may feel annoyed by restarting the device 14. When the control system 20 determines that the indoor activity state is the leaving state, it switches the operation state of the first device 14a to a stopped state and maintains the operation state of the second device 14b in an operating state. When the person returns to the room 11, it is determined that the indoor activity state has changed from the leaving state to the active state, so only the first device 14a is restarted. Since it is not necessary to restart the second device 14b, the person is less likely to feel annoyed.

[0084] A third function of this embodiment will be described. The control system 20 is configured to perform different controls between the first device 14a and the second device 14b. In the control system 20, the second device 14b is controlled so that it is less likely to start or stop operation than the first device 14a. Since the second device 14b has a greater impact on people when it starts or stops operation than the first device 14a, the impact on people can be reduced compared to when the first device 14a and the second device 14b are controlled in the same way.

[0085] A fourth effect of this embodiment will be described. By setting the first period T1, the responsiveness of the second device 14b to start operation when a person enters the room 11 can be changed. By setting the second period T2, the responsiveness of the first device 14a to stop operation when a person leaves the room 11 or takes a break in the room 11 can be changed. By setting the third period T3, the responsiveness of the second device 14b to stop operation when a person leaves the room 11 can be changed. By setting the fourth period T4, the responsiveness of the device 14 to stop operation when a person leaves the building 10 can be changed. By setting the first period T1, the second period T2, the third period T3, and the fourth period T4, it is possible to balance the responsiveness of the device 14 to start and stop operation and the increase in unnecessary power consumption of the device 14 in accordance with the life of the person.

[0086] The fifth effect of this embodiment will be described. The indoor state determination unit 31 determines whether or not a person is present in the building 10 based on the locking information. After the person leaves the building, a warning can be issued to the person via an external terminal such as a smartphone, for example, to warn that the device 14 has been left on. By appropriately setting the fourth period T4, the warning can be issued early to facilitate the person's return to the building 10 after leaving the building.

[0087] The sixth effect of this embodiment will be described. The control system 20 is configured not to switch the operation state of the device 14 when the environmental state of the room 11 satisfies a predetermined environmental condition. For example, when the device 14 is an air conditioner, if the temperature of the room 11 is comfortable for people, the control system 20 can suppress an increase in power consumption by postponing the start of operation of the device 14.

[0088] <Effects of the embodiment> The effects of this embodiment will be described. (1) The building 10 has a control system 20. The control system 20 includes a human presence sensor 21 and a control device 30. The control device 30 has an indoor state determination unit 31 and an equipment control unit 32. The indoor state determination unit 31 is configured to determine an indoor behavior state based on detection information detected by the human presence sensor 21. The indoor behavior state includes an entry state, an active state, a resting state, an exit state, and an absent state. The equipment control unit 32 is configured to switch the operation state of the equipment 14 between an active state and a stopped state based on the indoor behavior state.

[0089] According to this configuration, the indoor behavior state includes a plurality of states related to the presence or absence of people in the room 11 and their behavior, so that the control device 30 can finely control the device 14 based on the behavior of people.

[0090] (2) The control system 20 further includes a lock sensor 22. The indoor state determination unit 31 is configured to determine the presence or absence of a person in the building 10 based on the lock information detected by the lock sensor 22. The device control unit 32 is configured to switch the operation state of the device 14 between an active state and a stopped state based on the indoor activity state and the presence or absence of a person in the building 10.

[0091] According to this configuration, the indoor state determination unit 31 can more accurately determine the presence or absence of a person in the room 11 based on the presence or absence of a person in the building 10. This allows the control device 30 to control the device 14 more precisely based on the actions of the person. For example, when there is no person in the building 10, the indoor state determination unit 31 can more accurately determine that there is no person in the room 11.

[0092] (3) The devices 14 include a first device 14a and a second device 14b. The second device 14b has a greater impact on people when it starts or stops operating than the first device 14a. The device control unit 32 is configured to control the first device 14a and the second device 14b such that the operating state of the first device 14a and the operating state of the second device 14b are different from each other in at least one of the indoor activity states.

[0093] According to this configuration, the first device 14a and the second device 14b can be controlled in different modes. For example, the device 14 can be controlled so that the first device 14a and the second device 14b start or stop operating at different times. The first device 14a and the second device 14b, which have different functions, can be operated in a detailed manner based on the presence or absence of people in the room 11 and their actions.

[0094] (4) The device control unit 32 is configured to set the operation state of the first device 14a to a stopped state and the operation state of the second device 14b to an operating state based on the indoor state determination unit 31 determining that the indoor activity state is a resting state.

[0095] According to this configuration, when a person is resting in the room 11, the first device 14a is in a stopped state, so that the power consumption of the first device 14a can be reduced.

[0096] (5) The device control unit 32 is configured to set the operation state of the first device 14a to the stopped state and the operation state of the second device 14b to the running state based on the indoor state determination unit 31 determining that the indoor activity state is the leaving state. The device control unit 32 is configured to maintain the operation state of the first device 14a in the stopped state and set the operation state of the second device 14b to the stopped state based on the indoor state determination unit 31 determining that the indoor activity state has changed from the leaving state to the not-in-the-room state.

[0097] According to this configuration, the operating state of the second device 14b is maintained even if a person moves from inside the room 11 to outside the room 11, so when a person returns to the room 11 from outside the room 11, it is not necessary to switch the operation state of the second device 14b from a stopped state to an operating state. This makes it possible to suppress the impact on the person caused by the stop of the operation of the second device 14b. Also, when the indoor behavior state changes from a left state to a not-in state, such as when a person moves from inside the room 11 to outside the room 11 and then does not return to the room 11, the second device 14b is in a stopped state, so that an increase in power consumption of the second device 14b can be suppressed.

[0098] (6) The control system 20 further includes an environmental sensor 23. The indoor state determination unit 31 is further configured to determine the environmental state of the room 11 from the environmental information detected by the environmental sensor 23. The device control unit 32 is configured to suspend switching of the operation state of the device 14 based on the indoor activity state when the environmental state satisfies a predetermined environmental condition.

[0099] According to this configuration, when the environmental state satisfies a predetermined environmental condition, switching of the operation state of the device 14 is suspended, so that an increase in power consumption of the device 14 can be suppressed.

[0100] (7) The control system 20 controls the devices 14 arranged in the rooms 11 of the building 10. The control system 20 includes a human presence sensor 21 and a control device 30. The control device 30 has an indoor state determination unit 31 and an equipment control unit 32. The indoor state determination unit 31 is configured to determine an indoor activity state based on detection information detected by the human presence sensor 21. The equipment control unit 32 is configured to switch the operation state of the devices 14 between an operating state and a stopped state based on the indoor activity state.

[0101] According to this configuration, the indoor behavior state includes a plurality of states related to the presence or absence of people in the room 11 and their behavior, so that the control device 30 can finely control the device 14 based on the behavior of people.

[0102] <Modification> The above-described embodiment is an example of the form that the building 10 and the control system 20 can take, and is not intended to limit the form. The building 10 and the control system 20 can take a form different from the form exemplified in the above-described embodiment. Examples of such a form include a form in which part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. Modified examples of the embodiment are shown below.

[0103] <First Modification> The environmental information may include, for example, information regarding at least one of the temperature, brightness, humidity, carbon dioxide concentration, and odor of the room 11. The environmental sensor 23 of this modification includes at least one of a temperature sensor, a light meter, a humidity sensor, a carbon dioxide concentration sensor, and an odor sensor. The predetermined environmental condition of this modification includes a condition regarding at least one of the temperature, brightness, humidity, carbon dioxide concentration, and odor of the room 11.

[0104] When the device 14 is a light, the predetermined environmental condition includes a condition related to the brightness of the room 11. When switching the operation state of the light from a stopped state to an operating state based on the indoor activity state, the device control unit 32 suspends switching of the operation state of the light if the room 11 is bright.

[0105] If the device 14 is an air conditioner having a dehumidifying function, the predetermined environmental condition may include a condition related to the humidity of the room 11. When switching the operation state of the dehumidifying function of the air conditioner from a stopped state to an operating state based on the indoor activity state, if the humidity of the room 11 is low, the device control unit 32 suspends switching of the operation state of the dehumidifying function of the air conditioner.

[0106] When the device 14 is a ventilation device, the predetermined environmental conditions may include conditions related to at least one of the humidity, carbon dioxide concentration, and odor of the room 11. When switching the operation state of the ventilation device from a stopped state to an operating state based on the indoor activity state, the device control unit 32 suspends switching of the operation state of the ventilation device if the humidity in the room 11 is low. When switching the operation state of the ventilation device from an operating state to a stopped state based on the indoor activity state, the device control unit 32 suspends switching of the operation state of the ventilation device until the carbon dioxide concentration in the room 11 becomes sufficiently low if the carbon dioxide concentration in the room 11 is high. When switching the operation state of the ventilation device from an operating state to a stopped state based on the indoor activity state, the device control unit 32 suspends switching of the operation state of the ventilation device until the odor in the room 11 becomes sufficiently weak if the odor in the room 11 is strong.

[0107] When the device 14 is a heating device, the predetermined environmental condition may include a condition related to temperature. When switching the operation state of the heating device from a stopped state to an operating state, if the temperature of the room 11 is sufficiently high, the device control unit 32 suspends switching of the operation state of the heating device.

[0108] <Other Modifications> One of an air conditioner, a ventilation device, a heating device, an automatic water faucet, and a cooking heater may be the first device 14a, and another device other than the first device 14a may be the second device 14b.

[0109] The human presence sensor 21 may be a carbon dioxide sensor. When there is a person in the room 11, the carbon dioxide concentration is higher than when there is no person. The indoor condition determination unit 31 of this modified example determines that there is a person in the room 11 when the carbon dioxide concentration detected by the carbon dioxide sensor is equal to or higher than a predetermined threshold. The indoor condition determination unit 31 of this modified example may determine whether there is a person in the room 11 or not based on the carbon dioxide concentration detected by the carbon dioxide sensor.

[0110] The human presence sensor 21 may include, for example, a camera. The indoor state determination unit 31 may be configured to be able to determine whether a person is inside or outside the room 11 from an image captured by the camera. When multiple people use the building 10, the indoor state determination unit 31 may determine where each of the multiple people is located in the building 10 from the image captured by the camera.

[0111] The control device 30 may be configured to input a user's operation via an external terminal. The user may be a person who uses the room 11, or may be a person outside the building 10. The external terminal is a terminal device such as a smartphone, a tablet terminal, or a PC. The device control unit 32 may be configured to control the device 14 based on the user's operation. The device control unit 32 may switch the operation state of the device 14 between an operating state and a stopped state based on the user's operation. The device control unit 32 may be configured to notify the user of the operation state of the device 14 when controlling the device 14 based on the indoor activity state.

[0112] The lock sensor 22 may be omitted from the control system 20. In this modification, the indoor state determination unit 31 does not need to determine whether or not a person is present in the building 10.

[0113] The environmental sensor 23 may be omitted from the control system 20. In this modification, step S14 may be omitted from the process of FIG.

[0114] The device 14 may include only one of the first device 14a and the second device 14b.

[0115] The first period T1, the second period T2, the third period T3, and the fourth period T4 may be set to different periods for each of the multiple devices 14.
