  The sensor module 2a (2) is an independent detection device, and the sensor module 2b (2) is a detection device provided inside the electric device 3 or as a part of the electric device 3. The area (space) 5 is divided into a plurality of areas. The inside of the area 5 composed of a plurality of areas is also referred to as “home”. In the present application, the house means a predetermined area (space) such as a certain site or a certain building. FIG. 1 shows four area Nos. Obtained by dividing the house into four areas. 1, No. 2, No. 3, No. Although four is shown, the number of areas may be plural, and is not limited to four. Also, FIG. 1, No. 2, one electric device 3 (including the sensor module 2 b) is arranged, and 3, No. 4 shows a case where one electric device 3 (not including the sensor module) and one sensor module 2a are arranged, but the present invention is not limited to such a form. Area No. 1, No. 2, No. 3, No. Two or more electric devices 3 may be arranged in each of the four, and two or more sensor modules 2 may be arranged.

  The controller 1 is connected to the plurality of sensor modules 2 via the communication network 4, can communicate with the plurality of sensor modules 2, and can acquire sensor data indicating a state detected by the plurality of sensor modules 2. The controller 1 is connected to the plurality of electric devices 3 via the communication network 4, can communicate with the plurality of electric devices 3, and transmits device data indicating operation states of the plurality of electric devices 3 and contents of user operations. It can be obtained and can control a plurality of electric devices 3. The electric device 3 is, for example, a home appliance. The plurality of electric devices 3 can include at least one of a heating device, a cooling device, an air conditioner, a video device, an audio device, and a lighting device. The communication network 4 used for communication between the plurality of sensor modules 2 and the controller 1 and for communication between the plurality of electric devices 3 and the controller 1 may be wired or wireless. The method of wired communication is, for example, Ethernet (registered trademark) which is a wired LAN (Local Area Network) or serial communication. The method of wireless communication is, for example, WiFi as a wireless LAN, WiSUN (Wireless Smart Utility Network), iBeacon, or the like.

  The controller 1 can acquire sensor data from the sensor module 2 and use it. The sensor data acquired from the plurality of sensor modules 2 includes, for example, a plurality of area Nos. 1, No. 2, No. 3, No. 4, data (human detection data) indicating the presence of the movement of the user 6 (movement of an object), data indicating that the user 6 has performed an operation on a plurality of electric devices 3 (for example, a power switch of a lighting device). Signal indicating that the operation state of the plurality of electric devices 3 has been changed (for example, a signal indicating a change in the volume of the audio device). Specifically, the controller 1 can acquire operation state data indicating the operation state of the electric device 3 and operation content data indicating the content of the user operation of the electric device 3. Data can also be used as sensor data. For example, when an on / off operation of a power switch of an electric device (for example, a heating device) in a certain area is performed, it can be determined that a person (user) exists in this area. The operation content data can be used as human detection data in the same manner as the sensor data of the sensor module 2. Further, for example, when the volume level of an electric device (for example, an audio device) in a certain area is equal to or higher than a predetermined level, it is determined that there is a high possibility that a user exists in this area. Since it is possible, the operating state data can be used as human detection data in the same manner as the sensor data of the sensor module 2. Therefore, the human detection data as the sensor data in the present application includes not only the sensor data of the sensor module 2 but also the operation state data of the electric device 3 and the operation content data of the electric device 3.

  FIG. 2 is a block diagram showing a schematic configuration of the sensor module 2 and the controller 1 shown in FIG. As illustrated in FIG. 2, the sensor module 2 detects a state (for example, a physical quantity) in each area and outputs a detection signal (sensor data) according to a detection result (for example, detects a moving object). A human sensor 21, a sensor control unit (for example, a control circuit) 22 that controls the entire operation of the sensor module 2, a communication unit (for example, a communication circuit) 23 such as a network interface, and the like, and sensor data is stored. (For example, a semiconductor memory) 24. The sensor control unit 22 can communicate with the communication unit 11 of the controller 1 via the communication unit 23 and the communication network 4. The sensor control unit 22 can receive sensor data acquisition timing information from the controller 1. The communication unit 23 of the sensor control unit 22 communicates with the communication unit 11 of the controller 1 via the communication network 4. In addition, the sensor control unit 22 may transmit the sensor data stored in the sensor storage unit 24 to the controller 1 via the communication unit 23 at each time interval (at a constant cycle) based on the acquisition timing information. it can. However, the configuration of the sensor module 2 is not limited to that shown in FIG. For example, when the sensor module 2 b is a part of the electric device 3, the communication unit of the electric device 3 may be used instead of the communication unit 23, and the storage unit of the electric device 3 may be used instead of the sensor storage unit 24. May be used.

  As shown in FIG. 2, the controller 1 includes a communication unit 11, a control unit 12, a storage unit 13, an operation unit 14 into which a user instruction is input, and a display unit 15 for displaying information. . The operation unit 14 is, for example, a keyboard or a mouse. The display unit 15 is a display device such as a liquid crystal display. The operation unit 14 and the display unit 15 may be a touch panel type display input device formed integrally. The control unit 12 includes an area management unit 121, a history management unit 122, a presence detection unit 123, a behavior estimation unit 124, and a device control unit 125. “Present” is an area (place) where a person (user) exists. “Presence detection” refers to specifying an area where a user is present. The storage unit 13 includes a data history storage unit 132 and an area data storage unit 131. The data history storage unit 132 and the area data storage unit 131 may be separate storage units (for example, semiconductor memories) or different storage areas of the same storage unit (for example, semiconductor memories). The history management unit 122 causes the data history storage unit 132 to store one or more sensor data received by the communication unit 11 as a data history. The data history is sensor data for a predetermined period (for example, data of the past year, etc.).

  Sensor module 2 are known or are installed in advance in which area. The controller 1 can acquire the installation position of the sensor module 2 using, for example, installation information according to the ECHONET Lite protocol (a communication protocol formulated by the Echonet Consortium), or use the sensor module 2 to provide a latitude and longitude sensor. The information can be obtained by providing the information or by inputting the position information to the storage unit 13 of the controller 1 when the sensor module 2 is installed. In addition, for example, when the communication unit 23 uses wireless communication, the controller 1 determines the radio wave intensity at the time of communication with an access point (not shown) whose installation location is known (the stronger the radio wave intensity, the more the access point becomes. Close), area data can be obtained. Furthermore, the controller 1 can calculate the location of the communication unit 23 by using the difference in the radio wave intensity at the time of communication with an access point whose two or more set positions are known. Further, it is also possible to determine the position of the sensor module in the house based on the illuminance sensor provided in the sensor module 2 and the time. For example, obtaining (estimating) the installation position of the sensor module by comparing the data history indicating the relationship between the in-house time and the illuminance measured in advance and the data of the illuminance sensor acquired from the sensor module 2. Becomes possible. The association between the sensor module 2 and the installation area is stored in the area data storage unit 131.

  The presence detection unit 123 detects an area (location area) where a person (user) is present from the sensor data received by the communication unit 11. The sensor data used for detecting the area where the user is present may be, for example, human detection data output from a human sensor that is the sensor unit 21 that detects a motion. The sensor data used to detect the area where the user is present includes a human sensor using an infrared sensor, a sensor that detects a user by analyzing image data obtained by camera shooting, and a power switch of the electric device 3. Operation content data based on ON and OFF and operation content data based on an operation input by a user of the electric device 3 may be used. Further, the presence detection unit 123 may determine whether or not the area is where the user is present, by combining two or more of these sensor data.

  For example, even when the motion sensor as the sensor module 2 that detects the motion of the user detects the motion (when outputting sensor data), when the motion of the user stops, the motion sensor detects the user. Disappears (outputs no sensor data). After the detection of the user by the human sensor, the operation button of the lighting device as the electric device 3 is operated. For example, if the lighting device is turned on, the lighting device is installed while the lighting device is turned on. There is a high possibility that the user exists in the area where the user exists, and it can be determined that the user exists. However, there is a case where the user who performs the lighting operation moves to another area while the lighting device as the electric device 3 is turned on. For this reason, when the detection of the user by the human sensor as the sensor module 2 does not continue for a predetermined period of time or longer (for example, when the motion detection is not repeated for a period of time or longer), the illumination is performed. Even when the device is on, there is a high possibility that the user does not exist in the area where the lighting device is set (that is, it can be estimated that the user does not exist). In addition, the operation of another electric device can be considered in detecting that a user is present in a certain area. For example, information of an infrared sensor by a remote controller, such as an operation of turning on and off a television, which is a video device serving as the electric device 3, and an operation of switching a channel of the television, is used as data for presence detection. can do. As described above, by using a plurality of sensor data in combination, more accurate presence detection can be performed.

  Further, the presence detection unit 123 stores, in the area data storage unit 131, for each area (existing area) where the detected user is present, a history indicating that the user is present in that area (existence history). Save. “Presence history” is the presence time and presence time for each area. “Presence time” is the time at which the user is present in the area. The presence time is the time when the user entered the area (entry time), the time when the user left the area (exit time), or both. “Presence time” is the time (period) during which the user exists in the area. The presence history stored in the area data storage unit 131 is read out at the time of the next presence detection and used for the presence detection. For example, when there is a presence history indicating that the user was present in the same area at the same time in the past (for example, the past five weeks), the presence detection unit 123 determines that the user is present in that area. If there is no presence history, the user makes a determination such as reducing the certainty (presence probability) that the user is present in the area. You may. By performing the presence detection in consideration of the calculated probability from these presence histories, the accuracy of the presence detection can be further improved.

  The behavior estimation unit 124 detects (estimates) the behavior of the user who has moved across the area (that is, has moved beyond the boundary of the area) from the value indicated by the sensor data acquired from the sensor module 2. For example, area No. 1 is activated (that is, a moving user is detected), and immediately after that, the area No. 1 is detected. No. 1 adjacent to area No. 1 When the sensor module 2 of No. 2 is activated (that is, the user is detected), the user inputs the area number. 1 to area No. It is highly probable that the user has moved to area No. 2. 1 to area No. It is determined (estimated) that it has moved to 2.

  In addition, the behavior estimating unit 124 sets the area No. Area No. as the sensor module 2 of No. 1 When the user is reflected in a captured image output from the camera (imaging device) that captures the area No. 1 (that is, the presence of the user is detected from the captured image), The user is no longer shown in the captured image output from the camera that captures the area No. 1 (that is, the presence of the user is no longer detected from the captured image). No. 1 adjacent to area No. 1 Assuming that the user is reflected in the captured image output from the camera as the sensor module 2 of the second (that is, the presence of the user is detected from the captured image), the user is notified of the area No. 2. 1 to area No. It is highly probable that the user has moved to area No. 2. 1 to area No. It is determined (estimated) that it has moved to 2.

  In addition, the behavior estimating unit 124 can determine (estimate) behavior involving the movement of the user with higher accuracy by combining the values indicated by the plurality of sensor data (that is, increase the reliability of the estimation result). it can. For example, the behavior estimating unit 124 sets the area No. No. 1 sensor module 2 detects the user and the area No. 1 is detected. 1 is turned off, and immediately after that, the area No. 1 is turned off. No. 1 adjacent to area No. 1 The sensor module 2 of No. 2 detects the user and the area No. When it is detected that the lighting device of No. 2 is turned on, the area No. 2 is detected. 1 to area No. 2 can be determined (estimated) with higher accuracy that the user has moved to 2.

  The area management unit 121 manages information (area data) relating to a plurality of areas used by the behavior estimation unit 124, stores the area data in the area data storage unit 131, reads the area data from the area data storage unit 131, The area data stored in the data storage unit 131 is updated. The area management unit 121 considers, for example, the entire range of the house as a range to which the user can move, and divides the entire range of the house into a plurality of areas (that is, determines the arrangement and boundaries of the plurality of areas). In addition, the area management unit 121 determines that the user stays in the area for a certain period of time after moving into the certain area, and that the user does not stay in the certain area for more than the certain time, and passes through the area (ie, the certain time). The area type can also be classified by regarding the area (which moves to another area within this area) as an area of a different type. The type of area is, for example, a living room, a bedroom, a kitchen, a children's room, a corridor, an entrance, a bathroom, a toilet, and the like. The type of area includes an area in which the user is expected to stay for a long time (eg, a room), an area in which the user is not expected to stay for a long time (eg, a corridor, an entrance), and the user stays but moves within one hour. It may be an area (bathroom, toilet, etc.). The device control unit 125 can determine a default value of the sensor data acquisition frequency (the number of times of acquisition of sensor data per unit time) for each type of area determined by the area management unit 121. In addition, the area management unit 121 classifies, for each of the plurality of areas, the type of the plurality of areas based on the data history of the time period in which the user stays for a certain time or more in a day and the number of people who stay for a certain time or more. You can also.

  The area data storage unit 131 stores area data. The area data can include, for example, an area name, an area ID (identifier), an area type classified by the area management unit 121, a sensor data acquisition frequency determined for each area type, and the like. In addition, the area data storage unit 131 can also store, for each of the plurality of areas, a detection result as to whether or not the area is an area where the user is present (existing area). The area data stored in the area data storage unit 131 is input in advance and is updated by the area management unit 121. The plurality of areas in the house include, for example, a living room, a kitchen, a corridor, a bathroom, and the like. Of the plurality of areas, entrances, corridors, and the like can be classified into areas that are passed by the user when the user moves, but that cannot be stopped by the user. In a plurality of areas, such as a washroom, a bathroom, a toilet, etc., the type of the area can be classified into an area in which the user stays for less than a certain time. Among a plurality of areas, such as a living room, a dining room, and a bedroom, the type of the area can be classified into an area where the user stays for a long time. The area data storage unit 131 stores the type of area together with the area data.

  The area management unit 121 can update the area data stored in the area data storage unit 131 by a user input from the operation unit 14. For example, when providing a partition in one room and changing the room to two rooms, the area management unit 121 changes the room that was one area into two areas corresponding to the room (1) and the room (2). The area data stored in the area data storage unit 131 can be updated so as to be separately managed. In this way, by appropriately setting the area, it is possible to acquire only the sensor data of the necessary area and efficiently control only the electric device 3 in the area where the user exists.

  Further, the area management unit 121 may add, delete, or update the area data based on the history of the sensor data and the history of the area data. For example, if the living dining room is integrated and there is a user in the living room, the history that there is always a user in the dining room is detected a certain number of times or more (or over a certain period of time). The management unit 121 can update the living area and the dining area as the same area.

  The device control unit 125 stores the electric devices in the presence area detected by the presence detection unit 123 and the destination area (predicted destination area) of the user estimated by the behavior estimation unit 124 in the presence area. Control is performed to make the user comfortable and comfortable for the user who has moved to the destination area. Here, the "comfortable state" refers to a comfortable state in which the predetermined fixed values of temperature and humidity are changed to other values that the user feels comfortable. The device control unit 125 can set the fixed value to, for example, a value obtained by calculating the temperature and the humidity from a value in a range that is generally pleasant with the discomfort index. Further, the device control unit 125 can set the fixed value to a value indicating a state in which the user feels comfortable in consideration of a PMV (Predicted Mean Vote) value. Further, the device control unit 125 can determine the fixed value by a different method depending on the purpose. For example, the device control unit 125 can set the fixed values to values where the temperature and the humidity are equal to or less than certain values in order to achieve the purpose of avoiding heat stroke. In addition, the device control unit 125 can set the fixed value to a value where the humidity is equal to or less than a certain value in order to prevent the propagation of bacteria or viruses. Further, the device control unit 125 can set the fixed value to a value at which the humidity is equal to or less than a certain value in order to prevent the propagation of mites. Furthermore, the device control unit 125 can set the fixed value in accordance with an outdoor environment value such as an outdoor temperature and humidity so that a difference between the outdoor temperature and the humidity does not become too large.

  The “comfortable state” can also be determined according to the presence time in the area where the user was before moving. If the user's presence time in the area that existed immediately before is longer than a certain length, the user regards the temperature and humidity of the area as a comfortable state and moves to the temperature and humidity. The device can be controlled so as to reduce the difference between the temperature and the humidity in the preceding area.

  Further, the "comfortable state" includes automatically controlling the electric device 3 which is a necessary controlled device in the area. For example, the lighting device that is the electric device 3 in the destination area is turned on, the air conditioner that is the electric device 3 in the destination area is controlled so that the wind direction is directed to the user, and the TV that is the electric device 3 in the destination area is turned on. For example, adjusting the volume.

  The user's input is, for example, input from the operation unit 14 provided in the controller 1. Further, the user's input may be performed by an operation in which an option is displayed on the display unit 15 as a button (operation button on a touch panel) and the user selects it with a finger. Further, the user's input may be performed by wireless communication from a mobile terminal (for example, a smartphone, a mobile phone, or the like) connected to the communication network 4.

<< 1-2 >> Operation of First Embodiment FIG. 3 is a flowchart showing an area update process of the controller 1 included in the device control system according to the first embodiment. As shown in FIG. 3, first, the area management unit 121 in the control unit 12 determines whether there is a user input (for example, an input from the operation unit 14) for instructing an area update (step S30). When determining that there is a user input instructing an area update (YES in step S30), area management section 121 updates area data indicating an area in the house (step S31).

  Next, the area management unit 121 sets the area number. N (N is a positive integer) indicating the time zone in which the user is present (presence data) and area No. N is compared with the data indicating the time zone in which the user is present (existence data) in the comparison target area other than the area No. N (step S32). It is determined whether or not the presence data of N is equal to the presence data of the comparison target area (step S33). Also, if the determination in step S30 is NO, the process proceeds to steps S32 and S33. The area management unit 121 stores the area No. N, the presence data in the comparison target area is equal to the presence data in the comparison target area (YES in step S33). N and the comparison target area are integrated (step S34). In determining whether or not the presence data is equal (Step S33), the area management unit 121 determines that the data match when the data matching rate is equal to or more than a certain value (a certain reference value). , Or a method of judging a match when the data mismatch rate is equal to or less than a certain value, or when the match rate is equal to or more than a certain value (a certain reference value) for a certain period or more in the history of the presence data. And a method of determining that they match.

  FIG. 1 to No. FIG. 8 is a diagram illustrating an example of whether or not a person (user) exists in 8 (present state). In the example of FIG. 5 and the area No. 5 6 are recorded in exactly the same time zone. For example, when such a pattern continues for a certain period (for example, one week) or more, the area No. 5 and area No. 6 can be determined to be the same.

  Next, as shown in FIG. When the presence data of N and the presence data of the comparison target area (for example, the adjacent area) are equal, these areas are integrated (step S34). For example, in the example shown in FIG. 4, the area management unit 121 determines that the area No. where the same presence data pattern has continued for a certain period or more. 5 and area No. 6 can be integrated as the same area to form a new area.

  Next, the area management unit 121 performs a loop process so that the presence data is compared for all the areas (steps S35 and S36).

  Next, the area management unit 121 stores the updated area data in the area data storage unit 131 (Step S37). The area management unit 121 updates the area data stored in the area data storage unit 131, so that the device control unit 125 in the control unit 12 eliminates duplication of processing for each area and performs sensor It is possible to efficiently acquire data and control the electric equipment 3 in a necessary area at an appropriate timing. Further, the area management unit 121 updates the area according to the user's specification or data history, so that the device control unit 125 can perform efficient control of electric devices suitable for the user's behavior for each area. it can.

  FIG. 5 is a flowchart showing an operation of the sensor module 2 in the device control system according to the first embodiment. First, the sensor control unit 22 determines whether or not it is time to acquire sensor data based on the sensor acquisition cycle (for example, a time for each fixed period) (step S1). The sensor control unit 22 can determine that the time based on the sensor acquisition cycle has been reached when the elapsed time from the previous acquisition (detection) of the sensor data has reached a predetermined reference time. If the time based on the sensor acquisition cycle has been reached (YES in step S1), the sensor control unit 22 causes the sensor unit 21 to detect the state of the detection target and acquire sensor data, and stores the sensor data in the sensor storage unit 24. It is stored (step S2). If the time based on the sensor acquisition cycle has not been reached (NO in step S1), the sensor control unit 22 determines whether a data request has been made from the controller 1 (step S3). When there is a data request from the controller (YES in step S3), the sensor control unit 22 causes the sensor unit 21 to acquire sensor data (perform state detection), and the acquired sensor The data is transmitted from the communication unit 23 to the controller 1. If there is no data request from controller 1 (NO in step S3), the process returns to step S1. The cycle of the data request from the controller 1 may be, for example, a predetermined cycle.

  FIG. 6 is a flowchart illustrating an operation of the controller 1 in the device control system according to the first embodiment. As shown in FIG. 6, first, the presence detection unit 123 in the control unit 12 detects in which area the user is present (location detection) based on the sensor data. An existing area is specified (step S10). The sensor data used for the presence detection is read from the data history storage unit 132 via the history management unit 122, and the area data used for the presence detection is read from the area data storage unit 131.

  Next, the behavior estimating unit 124 in the control unit 12 acquires sensor data in the presence area specified as having a user (step S11). The behavior estimating unit 124 acquires sensor data in the presence area from the data history storage unit 132 in order to estimate the behavior of a user existing in the presence area. However, when the data stored in the data history storage unit 132 is data older than a predetermined threshold period, the behavior estimation unit 124 acquires the latest sensor data from the sensor module 2.

  Next, the behavior estimating unit 124 estimates the destination area of the user (predicted destination area) based on the data stored in the data history storage unit 132 (step S13).

  The device control unit 125 acquires the sensor data of the destination area (Step S14). The device control unit 125 acquires the sensor data in the movement destination area from the data history storage unit 132. If the data stored in the data history storage unit 132 is older than a predetermined threshold period, the device control unit 125 Get the latest sensor data.

  Next, the device control unit 125 controls the electric device 3 in the presence area (Step S15). For example, the device control unit 125 controls devices necessary for the user to spend comfortably based on information indicated by the sensor data in the presence area.

  Next, the device control unit 125 controls the electric device for the destination area acquired in step S14 (step S16). The device control unit 125 controls, for example, devices necessary for a user to spend comfortably based on information indicated by sensor data in the area.

  Next, the device control unit 125 updates the acquisition cycle of the sensor data in the area (Step S17). The device control unit 125 can change the acquisition cycle in these areas in a short period of time so that the acquisition frequency of sensor data in the presence area and the destination area increases, for example. In addition, the device control unit 125 updates the presence area as the presence area changes with the movement of the user, and also updates the sensor data acquisition cycle for the area.

  FIG. 7 is a flowchart illustrating the presence detection process (step S10) in the controller 1 of the device control system according to the first embodiment. As shown in FIG. 7, first, the presence detection section 123 determines whether or not the presence detection processing is the first time (step S100). The presence detection unit 123 reads whether or not the presence detection result for each area is stored from the area data storage unit 131. If the result is not stored, the presence detection unit 123 performs the presence detection for all areas because it is the first time. Execute.

  If it is the first presence detection process (YES in step S100), presence detection section 123 sets an area ID to N, which is an area number (step S101).

  In the next step S102, the presence detection unit 123 reads data from the data history storage unit 132, and reads the area No. This is a step of determining whether a user exists in N. The determination is made as to whether or not the motion sensor has responded (that is, whether or not motion has been detected), whether or not the user is reflected in the camera image, and the user's body temperature (above the reference temperature) with the infrared sensor. It is performed by combining a plurality of these pieces of sensor information, such as whether or not the operation has been performed, whether or not the electric device has been turned on, whether or not the electric device has been operated, and the like.

  In the next step S103, the presence detection unit 123 sets the area number. When it is detected that the user exists in N, the presence state is saved. The presence status is stored in the area data storage unit 131.

  In the next step S104, the presence detection unit 123 updates N to the number of the next area ID.

  In the next step S105, the presence detection unit 123 is a step for determining whether or not N has performed presence detection for all areas. If there is an area to be subjected to the presence detection, the presence detection unit 123 returns to step S102 and updates the area N for the updated N. The presence detection of whether a user exists in N is performed.

  FIG. 8 is a flowchart illustrating the operation (step S12) of the behavior estimation unit 124 of the controller 1. As shown in FIG. 8, the action estimating unit 124 determines in step S111 that the area No. Reading of the N presence data is performed. The presence data is stored together with the area data in the area data storage unit 131 by the presence detection processing in step S10. Therefore, there is no need to receive sensor data from the sensor module 2 of the behavior estimating unit 124 or perform another process for detecting presence using the data in the data history storage unit 132. The presence data can include not only whether or not the user is present, but also the time during which the user is present.

  In the next step S112, the action estimating unit 124 sets the area No. The N sensor data is read. As a result of step S111, the area No. When the user exists in the area No. N, the behavior estimating unit 124 sets the area No. The sensor data in N is read. At this time, first, the sensor data is read out from the data history storage unit 132, and if a time equal to or longer than the threshold time has elapsed since the acquisition of the latest stored data, the latest data is acquired from the sensor module and updated. . The threshold time is predetermined for each sensor module, and is stored in the data history storage unit 132 together with the sensor data.

  In the next step S113, the behavior estimating unit 124 sets the area No. The destination area from N is estimated. The behavior estimating unit 124 estimates the destination area by using the area No. This can be performed using a camera installed in the camera N or a user's movement using an infrared sensor. In addition, the behavior estimation unit 124 can also estimate the destination area using the area movement history stored in the data history storage unit 132 (that is, determining that the area moves in the same manner as this history). In addition, the behavior estimating unit 124 sets the area No. The destination area can also be specified from the power states and operation histories of the electric devices other than N.

  In the next step S114, the action estimating unit 124 sets the area No. It is determined whether or not the user exists at the destination (for example, area No. X) from N. This can be determined by reading data from the area data storage unit 131.

  In the next step S115, the action estimating unit 124 sets the area No. Read the sensor data of X. First, the behavior estimation unit 124 reads the sensor data from the data history storage unit 132, and acquires the latest data from the sensor module when the time that is equal to or longer than the threshold time has elapsed since the acquisition of the latest saved data. ,Update. The threshold time is predetermined for each sensor module, and is stored in the data history storage unit 132 together with the sensor data.

  In the next step S116, the action estimating unit 124 sets the presence area No. of the movement source. N and the destination area No. The difference between the values indicated by the X sensor data is calculated. The behavior estimating unit 124 detects, for example, a difference in environmental data such as temperature, humidity, and illuminance.

  In the next step S15, the action estimating unit 124 sets the area No. N, and in the next step S16, the action estimating unit 124 sets the area No. X device control is performed. Details of the device control process will be described with reference to FIG.

  In the next step S118, the behavior estimating unit 124 sets the area No. in the area data storage unit 131. N and area No. X's presence data is updated. If the user sets the area No. N to area No. X by moving to area No. X N, the user of area No. The presence data of N is updated to information indicating that there is no user. In addition, area No. If there is no user in advance, the area No. X, it is determined that a user exists in area No. X. X is updated to field data indicating that a user exists.

  FIG. 9 is a flowchart illustrating the operation (steps S15 and S16) of the device control unit 125 of the controller 1.

  In step S121, the device control unit 125 sets the area No. The N electric devices 3 are controlled. Area No. N to area No. X, the user moves to area No. X. If the user no longer exists in area No. The power of the device operating at N is turned off or the set temperature is changed to reduce the power consumption.

  In the next step S122, the device controller 125 sets the area No. It is determined whether or not the presence time of N is equal to or greater than a certain value. Area No. If there is a user in N for a certain period of time or more, the environment can be considered to be in a state suitable for the presence of the user. Also, by taking into account the burden on the user due to the difference from the environment before the movement, the difference between the environment at the source area and the environment at the destination area can be reduced. Therefore, in step S123, the device control unit 125 sets the area No. N and area No. Calculate the difference of X. In this step, the area No. N and area No. The values indicated by the sensor data such as the temperature and humidity of X are compared.

  In the next step S124, the device control unit 125 sets the area No. X by controlling the device of area No. X according to the result of step S123. X environment as area No. Approach N environment.

  In the next step S125, the device control unit 125 sets the area No. X area No. As a result of the comparison with N, other devices different from the device to be controlled are controlled. The device control unit 125, for example, stores the area No. X by moving to area No. X. X lighting equipment is turned on, and area No. X is turned on. N when the attendance time of the area No. N is less than a predetermined time. N regardless of the environment of area No. X by controlling an air conditioner, a dehumidifier and the like. Make X's environment more comfortable.

  The device control in the device control (steps S15 and S16 in FIG. 8) shown in FIG. 9 is, for example, temperature and humidity and airflow control for realizing a comfortable indoor thermal environment in consideration of a PMV (Predicted Mean Vote) value. is there. In addition, in consideration of the behavior estimation, it is also possible to perform temperature and humidity and airflow control for bringing the environment of the presence area where the user is currently located closer to the environment of the destination. For example, when it is estimated to move to the entrance, when there is a great difference between the outdoor and indoor environments, or when suddenly moving to a hot place or moving to a cold place, a heavy burden is imposed on the body. Therefore, it is possible to control the indoor environment to be as close to the outdoor state as possible. In such a case, the PMV value is taken into consideration, and the comfort can be controlled while maintaining the comfort. Further, the control may be such that the state of the device such as the power supply of the device in consideration of the behavior estimation is changed. The control to change the state of the device is, for example, a control to increase the volume of the television or to decrease the volume of the television when moving from the living room to the kitchen.

<< 1-3 >> Effects of First Embodiment As described above, according to the first embodiment, the area where the user is present and the destination area are specified by the presence detection unit 123 and the behavior estimation unit 124. By acquiring sensor data for each specified area, controlling the frequency of acquisition of sensor data, and controlling devices for each area according to the information indicated by the acquired sensor data, devices in the required area can be identified. It becomes possible to control efficiently.

  Conventionally, when all sensor data in a house is acquired, if acquisition is performed sequentially by time-division processing, it takes a long time to acquire sensor data necessary for controlling devices in an area where a user is present. In some cases, it takes time, and the processing load for acquiring and analyzing the sensor data increases, and the processing for controlling the device may take time. On the other hand, in the first embodiment, by specifying an area to be subjected to device control, sensor data of a necessary area is efficiently obtained, and device control for realizing an optimal environment is performed at an appropriate timing. It is possible to do with.

  Furthermore, the sensor data acquisition frequency of the area that only passes when the user moves is increased, the sensor data acquisition frequency of the area that stays only for a certain time is set slightly lower, and the sensor data acquisition frequency of the area that stays for a long time is set even lower By doing so, it is possible to appropriately adjust the acquisition frequency of the sensor data depending on the stay time of the user in the movement. For this reason, unnecessary acquisition of sensor data can be suppressed, the load on the controller due to acquisition and analysis of sensor data can be suppressed, and electric devices can be controlled at appropriate timing.

<< 2 >> Embodiment 2
<< 2-1 >> Configuration of Second Embodiment FIG. 10 is a block diagram showing a schematic configuration of a device control system according to a second embodiment of the present invention. 10, the same or corresponding components as those shown in FIG. 1 are denoted by the same reference numerals as those shown in FIG. FIG. 11 is a block diagram illustrating a schematic configuration of the sensor module 2 and the controller 1a of the device control system according to the second embodiment. 11, the same or corresponding components as those shown in FIG. 2 are denoted by the same reference numerals as those shown in FIG. As shown in FIGS. 10 and 11, the controller 1 a acquires a user's request, and based on the request, information for specifying a request target sensor module that is a request target among the plurality of sensor modules 2. And a data request control unit 201 for determining a sensor data acquisition cycle in the requested sensor module 2. Further, the controller 1a acquires an individual profile which is individual information of the user (for example, information on tastes), and identifies the sensor module corresponding to the individual profile among the plurality of sensor modules 2 based on the individual profile. And an individual profile control unit 202 that determines an acquisition cycle of the sensor data in the sensor module corresponding to the individual profile. As shown in FIGS. 10 and 11, the controller 1a of the device control system according to the second embodiment differs from the controller 1a in that the control unit 12a includes a data request control unit 201 and an individual profile control unit 202. This is different from the controller 1 of the device control system according to the first embodiment. However, the controller 1a according to the second embodiment may include only one of the data request control unit 201 and the individual profile control unit 202.

  The data request control unit 201 performs the necessary sensor data type, sensing cycle, and sensing accuracy according to a data request profile indicating the type of sensor data and the sensing cycle (acquisition cycle of sensor data) according to the function and condition of the service. Is determined, and sensor data is acquired from the sensor module via the communication unit 11. This data request profile may be generated from an information table held in the storage unit 13 of the controller 1a, or may be obtained from an external storage device (not shown). The data request profile is determined by a service profile including service conditions and service functions changed based on individual factors such as a user's request, a user's age, and a user's gender.

  The function of the service specified by the service profile is, for example, the type of service to be provided, such as whether the function of the electric device in the house is a comfort control service, a health promotion service, or an online home delivery service. It is. Which service is requested is determined by, for example, a user input operation from the operation unit 14.

  The individual profile control unit 202 determines a service condition based on individual factors such as a user request, a user age, and a user gender. The individual profile is generated based on a user's request, age, gender, and the like registered in advance (for example, input by the user in advance). The user's request is, for example, a comfort control service, a health promotion service, or a home delivery service. When the user selects and requests these provided services, the service conditions of the individual profile become different. For example, if the required service function is a comfort control service for home appliances, and one of the service conditions is a comfortable temperature, the service condition of a comfortable temperature is, for example, a user who does not like heat. A condition indicating whether the user is a (hot person) or a user who does not like the cold (a cold person), and whether the user is a user (elderly person) of a first age or more that is determined. The required comfort varies depending on the condition indicating whether the user is a user (infant) under the age of 2, or the condition indicating whether the user is a woman or a man. For this reason, the service condition can be controlled by the individual profile control unit 202 so as to match the personality of the user.

  Fixed conditions such as the age and gender of the user are input in advance (for example, input by the user himself). The input is performed, for example, from the operation unit 14 provided in the controller. In addition, the input may be performed by displaying an option on the display unit 15 and selecting the option. In addition, the input may be performed from a mobile terminal via the communication unit 11 when a mobile terminal (not shown) is connected to the network.

  User preferences can also be used as user information for determining an individual profile. This is based on the search keyword used by the user on the mobile terminal connected to the communication network 4, the word used in the mail, or the word based on the result of voice recognition performed by the cloud server on the word used by the user input from the microphone. It becomes possible by extracting words related to the service. For example, whether the user is hot or cold depends on how many times the outside air temperature is high, or how often the user uses the word “hot” or how often the word related to “hot” is used. , Or use the word "cold" or how often to use the word related to "cold" in the individual profile to determine the user's preference for temperature. It can be reflected in service conditions.

  As described above, it is possible to determine the comfortable temperature setting as a service condition from the user's preference obtained by analyzing the information input by the user and the data history. For example, if the user is a male in his 20s who does not like heat (is hot) and the season is summer, the initial value of the comfortable temperature can be set to 23 ° C. Furthermore, for the temperature determined as the initial value, the word “hot” or “cold” is obtained from the input information of the remote controller when the user changes the set temperature of the air conditioner and the voice input from the microphone input of the mobile terminal. By reflecting the history information recognized by voice, it is also possible to change the comfortable temperature setting for the user. The changed comfortable temperature setting is stored in the storage unit 13 by the individual profile control unit 202.

  As described above, the service condition is determined by the individual profile control unit 202, and the data request profile is determined by the service profile. According to the determined data request profile, the data request control unit 201 controls data acquisition. For example, when the comfort control service of the electrical equipment in the house is indicated in the service profile, the data request profile should acquire the room temperature, the room humidity, the amount of the user's activity, the user's body temperature, the user's clothing state, and the like. Specified as data. The data to be acquired corresponding to the service can be stored in the controller 1a in advance in a fixed value depending on the service, or can be provided in advance as a file by a service provider, or can be provided via the communication network 4. It can also be set by downloading the information disclosed by the provider. The data acquisition cycle is also determined by the cycle at which the data to be acquired changes. For example, in the case of the comfort control service, the data acquisition acquires temperature and humidity once every 10 minutes, the user's activity amount acquires once every minute, and the user's body temperature and clothing state. Can be determined to be acquired at a timing when the amount of activity changes by a predetermined threshold or more. In addition, if the required data accuracy is a comfort control service, the accuracy is within a range required for the comfort control. For example, the temperature is 0.1 [° C.] unit, the humidity is 1% unit, the activity amount is 1 [cal] unit, the body temperature is 0.1 [° C.] unit, and the clothing state is 1 [clo] unit. , Etc. The data acquisition cycle, the data acquisition cycle and the accuracy can also be fixed in the controller in advance for each service, or can be provided by a service provider in a file or data, Can be set by downloading information disclosed by the service provider via the Internet.

  The individual profile control unit 202 can determine a service condition as an individual element of the user and change the data request profile based on the presence detection result indicating that a user detected by a human sensor or the like is present, for example. . By changing the data request profile, the data request control unit 201 can increase the frequency of acquiring sensor data in the area where the user exists, or acquire the latest value. For example, when a user is present in the living room, the control of the devices installed in the living room, the air conditioner, the air purifier, the ventilation fan, the lighting device, etc. is performed in order to make the state in the living area comfortable. At this time, the sensor data in the living room is reacquired to detect the latest state in the living room, but the data acquisition cycle is changed depending on the service function.

  The sensor control unit 22 of the sensor module receives a request for a data acquisition cycle from the data request control unit 201 via the communication unit 23 via the communication unit 23, and transmits sensor data.

<< 2-2 >> Operation of Second Embodiment FIG. 12 is a flowchart showing the operation of the controller 1a of the device control system according to the second embodiment. 12, processes that are the same as or correspond to the processes shown in FIG. 6 are assigned the same step numbers as the step numbers shown in FIG.

  As shown in FIG. 12, in step S9, the controller 1a reads a data request profile. The data request profile may be input from the outside, or may be read from a table held in the controller 1a (for example, the storage unit 13) according to the service profile. The controller 1a acquires sensor data according to the read data request profile. Further, compression according to data accuracy according to the data request profile is also performed.

  As shown in FIG. 12, the presence detection unit 123 in the control unit 12a detects in which area the user is present (location detection) based on the sensor data, and detects the presence of the user. The specified area is specified (step S10). The sensor data used for the presence detection is read from the data history storage unit 132 via the history management unit 122, and the area data used for the presence detection is read from the area data storage unit 131. Next, the behavior estimating unit 124 in the control unit 12a acquires sensor data in the presence area specified as having a user (step S11). The behavior estimating unit 124 acquires sensor data in the presence area from the data history storage unit 132 in order to estimate the behavior of a user existing in the presence area.

  Next, the behavior estimating unit 124 estimates the destination area of the user (predicted destination area) based on the data stored in the data history storage unit 132 (step S13). The device control unit 125 acquires the sensor data of the destination area (Step S14). Next, the device control unit 125 controls the electric device 3 in the presence area (Step S15). For example, the device control unit 125 controls devices necessary for the user to spend comfortably based on information indicated by the sensor data in the presence area. Next, the device control unit 125 controls the electric device for the destination area acquired in step S14 (step S16). The device control unit 125 controls, for example, devices necessary for a user to spend comfortably based on information indicated by sensor data in the area.

  Next, the device control unit 125 updates the acquisition cycle of the sensor data in the area (Step S17). The device control unit 125 can change the acquisition cycle in these areas in a short period of time so that the acquisition frequency of sensor data in the presence area and the destination area increases, for example. In addition, the device control unit 125 updates the presence area as the presence area changes with the movement of the user, and also updates the sensor data acquisition cycle for the area.

  The sensor control unit 22 of the sensor module receives a request for a data acquisition cycle from the data request control unit 201 via the communication unit 23 via the communication unit 23, and transmits sensor data. Except for the above, the configuration and operation of the second embodiment are the same as those of the first embodiment.

<< 2-3 >> Effects of Second Embodiment As described above, according to the second embodiment, in addition to the effects described in the first embodiment, a request from a user is taken into consideration, and More appropriate content control can be performed in consideration of user preferences.

  In addition, since the processing load for the acquisition and analysis of sensor data is reduced, device control can be performed at appropriate timing.

<< 3 >> Modification The sensor module 2 may be a wearable sensor worn by a user. The wearable sensor may have a function of measuring a user's body temperature, heart rate, and activity amount. The position of the wearable sensor may be such that position information can be acquired by a latitude and longitude sensor. In addition, the position of the wearable sensor can be determined (estimated) from the service data acquisition time and the illuminance at the position where the user is present.
