  Inside the room, 18 people are carrying out specific business activities, and the entrance to and exit from the room is done with two doors. In the present embodiment, the layout, devices, number of people, and the like are limited, but the present invention can be applied to a wider variety of layouts and devices. Furthermore, the present invention can be widely expanded and applied to the arbitraryness in the scalability of the space scale and the number of people and the arbitraryness in the user attribute and the type of work involved when viewed in individual units or group units. Moreover, this embodiment may be applied not only to indoor spaces as shown in FIGS.

  Note that the positioning server device 100 and the control server device 200 of this embodiment are installed outside the room shown in FIGS. In the present embodiment, the positioning server device 100 and the control server device 200 are not subject to power control, but these may be subject to power control.

  In this embodiment, network devices such as Wi-Fi access points, switching hubs, and routers constituting the communication network system are excluded from power control. However, these devices may be subject to power control. Is possible.

  The amount of power consumed by these network devices can be calculated as the amount of power obtained by dividing the total power in the LED lighting device 500, the air conditioner 700, and the tap 600 from the total system power.

  Each of the plurality of LED lighting devices 500, the plurality of taps 600, and the plurality of air conditioners 700 is remotely controlled by the control server device 200 via a network.

  That is, the LED lighting device 500 is remotely controlled by the control server device 200 with respect to the illumination range and illuminance. Specifically, the LED lighting device 500 is provided with an on / off switch that can be individually controlled remotely, and the on / off control is performed by the control server device 200 by a wireless control method using Wi-Fi. The LED lighting device 500 uses an LED lamp with a dimming function in consideration of low power consumption, and the dimming function is configured to be capable of remote control via Wi-Fi.

  The tap 600 is provided with a plurality of tap openings, and power supply on / off of each tap opening is remotely controlled by the control server device 200. That is, the tap 600 is provided with an on / off switch that can be remotely controlled individually for each tap opening. The on / off control is performed by the control server device 200 using a Wi-Fi wireless control scheme. Although the number of tap openings included in one tap 600 can be any number, an example in which one tap 600 is configured by four tap openings can be used.

  As shown in FIG. 6, one tap 600 is installed on each desk. The tap 600 can be connected to an electrical device (not shown), specifically, a desktop PC, a display device, a notebook PC, a printer device, and chargers. Further, the tap 600 has a function of measuring the power consumption of the electric device connected to the tap 600 and transmitting it to the control server device 200.

  In the present embodiment, a power source of a display device, which is a device in which a direct relationship with a person is important, is connected to the tap opening of the tap 600. The display device is a device that can be controlled by turning on / off the power supplied to the tap port by the control server device 200.

  Even when a desktop PC main body or printer device is connected to the tap 600, the control server device 200 cannot control the power supplied to the tap port by on / off due to the configuration of the device. For this reason, for desktop PCs, control software can be controlled by installing control software that can shift to the power saving mode or shutdown via the network, and return from the power saving mode or shutdown state. Is a manual operation by the user himself.

  Further, when a charger or a notebook PC at the time of charging is connected to the tap 600, it is always turned on for convenience. Note that devices connected to the tap opening of the tap 600 are not limited to these.

  Returning to FIG. 1, the positioning server device 100 receives the detection data of each sensor described above from each smartphone 300 or sensor group 301 possessed by a person in the room that is the control target area, and detects the position of each person in the room. The operating status is detected, and the position and operating status are transmitted to the control server device 200.

  FIG. 7 is a block diagram showing a functional configuration of the positioning server device 100. As shown in FIG. 7, the positioning server device 100 mainly includes a communication unit 101, a position specifying unit 102, an operation state detection unit 103, a correction unit 104, and a storage unit 110.

  The storage unit 110 is a storage medium such as a hard disk drive (HDD) or a memory, and stores various information necessary for processing of the positioning server device 100 such as indoor map data that is a control target area.

  The communication unit 101 detects each of the acceleration sensor, the angular velocity sensor, and the geomagnetic sensor mounted on the smartphone 300 or the acceleration sensor, the angular velocity sensor, and the geomagnetic sensor of the sensor group 301 separate from the smartphone 300 at regular intervals. Receive data. That is, the communication unit 101 receives an acceleration vector from the acceleration sensor, receives an angular velocity vector from the angular velocity sensor, and receives a magnetic orientation vector from the geomagnetic sensor.

  In addition, the communication unit 101 receives a captured image from the monitoring camera 400. Furthermore, the communication unit 101 transmits an operation state such as an absolute position of a human, which will be described later, a direction, and a posture, to the control server device 200.

  The position specifying unit 102 analyzes the received detection data and specifies the absolute position of the person in the room with the accuracy of the human shoulder width or stride. Details of the method of specifying the absolute position of the human by the position specifying unit 102 will be described later.

  The operation state detection unit 103 analyzes the received detection data and detects a human operation state. In the present embodiment, the movement state detection unit 103 detects whether the human is in a stationary state or a walking state as the movement state. Further, when the operation state is a stationary state, the operation state detection unit 103 indicates the operation state of the human direction with respect to the device in the control target area and whether the human posture is a standing state or a seating state based on the detection data. To detect.

  That is, when it is detected from the captured image from the monitoring camera 400 that the person has entered the room through the door, the operation state detection unit 103 detects the acceleration sensor, the angular velocity sensor, and the geomagnetic sensor of the smartphone 300 attached to the person who has entered the room. Or, using the time series data of the acceleration vector and the angular velocity vector among the detection data sequentially received from the acceleration sensor, the angular velocity sensor, and the geomagnetic sensor of the sensor group 301 separate from the smartphone 300, the human operating situation is Sequentially determine whether walking or standing. Here, the method of determining whether the human motion state is the walking state using the acceleration vector and the angular velocity vector is realized by the processing by the dead reckoning device disclosed in Japanese Patent No. 4243684. Then, when it is determined that the person is not in a walking state by this method, the operation state detection unit 103 determines that the person is in a stationary state.

  More specifically, the operation state detection unit 103 detects a human operation state as follows, similarly to the processing by the dead reckoning device disclosed in Japanese Patent No. 4243684.

  That is, the operation state detection unit 103 obtains a gravitational acceleration vector from the acceleration vector received from the acceleration sensor and the angular velocity vector received from the angular velocity sensor, subtracts the gravitational acceleration vector from the acceleration vector, and removes the vertical acceleration. Obtain time-series data of residual acceleration components. Then, the motion state detection unit 103 performs principal component analysis on the time-series data of the residual acceleration component to obtain the traveling direction of the walking motion. Furthermore, the motion state detection unit 103 searches for a pair of peak and valley peaks of the acceleration component in the vertical direction, and searches for a pair of valley peak and peak of the acceleration component in the traveling direction. Then, the operation state detection unit 103 calculates the gradient of the acceleration component in the traveling direction.

  Furthermore, the operation state detection unit 103 determines whether or not the gradient of the acceleration component in the traveling direction is equal to or greater than a predetermined value at the detection time of the valley peak at which the vertical acceleration component changes from the peak to the peak. If it is equal to or greater than the predetermined value, it is determined that the human motion state is a walking state.

  On the other hand, in the above processing, a peak-to-valley peak pair in the vertical acceleration component is not searched, or a trough peak-to-peak peak pair in the traveling acceleration component is not searched, or a vertical acceleration is detected. When the gradient of the acceleration component in the traveling direction is less than a predetermined value at the time of detection of the valley peak at which the component changes from the peak to the valley peak, the motion status detection unit 103 indicates that the human motion status is stationary. It is determined that

  If it is determined that the person is in a stationary state, the position specifying unit 102 determines that the position of the door is a stationary state from the reference position using the acceleration vector, the angular velocity vector, and the magnetic orientation vector as the reference position. The relative movement vector to the specified position is obtained. Here, as a method of calculating the relative movement vector using the acceleration vector, the angular velocity vector, and the magnetic azimuth vector, the method disclosed in the processing of the dead reckoning device disclosed in JP 2011-47950 A is used.

  More specifically, the position specifying unit 102 obtains a relative movement vector as follows, similarly to the processing of the dead reckoning device disclosed in JP 2011-47950 A.

  That is, the position specifying unit 102 obtains a gravity azimuth vector from the acceleration vector received from the acceleration sensor and the angular velocity vector received from the angular velocity sensor, and from the gravity azimuth vector and the magnetic azimuth vector received from the angular velocity vector or the geomagnetic sensor, The attitude angle is calculated as the moving direction. The position specifying unit 102 obtains a gravitational acceleration vector from the acceleration vector and the angular velocity vector, and calculates an acceleration vector generated by the walking motion from the gravitational acceleration vector and the acceleration vector. Then, the position specifying unit 102 analyzes and detects the walking motion from the gravitational acceleration vector and the acceleration vector generated by the walking motion, and determines the magnitude of the walking motion based on the detection result. And the acceleration vector generated by the walking motion, and the measurement result is used as a stride. Then, the position specifying unit 102 obtains a relative movement vector from the reference position by integrating the movement direction and the stride thus obtained. That is, the human position is detected in real time with an accuracy of human stride or shoulder width, for example, approximately 60 cm or less (more specifically, approximately 40 cm or less).

  When the relative movement vector is calculated in this way, the position specifying unit 102 specifies the absolute position after the movement of the person from the relative movement vector from the door and the indoor map data stored in the storage unit 110. To do.

  As a result, the position specifying unit 102 can specify up to which desk the person is located in the room. As a result, the shoulder width of the person, for example, approximately 60 cm or less (more specifically, approximately 40 cm). It is possible to specify the position of a person with an accuracy of less than about).

  The higher the position accuracy, the better. For example, assuming a scene in which two or more people are having a conversation, it is rare that they talk in contact with each other, and they are separated by a certain distance. Accordingly, when considering accuracy, the accuracy corresponding to the shoulder width or stride of a person, whether standing or sitting, is equivalent to the length from the waist to the knee.

  According to the anthropometric data published by the Ministry of Health, Labor and Welfare (Makiko Kawachi, Masaaki Mochimaru, Hiroshi Iwasawa, Seiji Mitani (2000): Japanese Human Body Size Database 1997-98, Ministry of International Trade and Industry, Industrial Technology Institute and JIS Center) The data (shoulder width) corresponding to the shoulder width of adolescents and elderly men and women is about 35 cm (34.8 cm) for the elderly women with the lowest average value, and about 40 cm (39.7 cm) for the highest adolescent men It has become. Similarly, the difference between the length from the waist to the knee (pubic bone joint upper edge height−femoral outer epicondyle height) is about 34 cm to about 38 cm. On the other hand, the stride when a person moves is 95 steps when walking 50 m, and is about 53 cm (50 ÷ 95 × 10) from now on, and the position detection method used in the present invention can have an accuracy equivalent to the stride. Therefore, the present embodiment is configured based on the above data on the assumption that the accuracy is 60 cm or less, preferably 40 cm or less. These data serve as a standard for considering accuracy, but are based on the Japanese and are not limited to these values.

  Further, when the absolute position of the person is specified and the person is stationary at the seat in front of the desk, the operation state detection unit 103 determines whether the human display device is in accordance with the direction of the magnetic direction vector received from the geomagnetic sensor. Determine the direction (orientation). In addition, when the person is stationary at the seat in front of the desk, the operation state detection unit 103 determines the posture of the person, that is, whether the person is standing or sitting from the acceleration component in the vertical direction of the acceleration vector.

  Here, as in the dead reckoning device disclosed in Japanese Patent No. 4243684, the gravitational acceleration vector is determined from the acceleration vector received from the acceleration sensor and the angular velocity vector received from the angular velocity sensor. Obtain the acceleration component in the vertical direction. Then, similarly to the dead reckoning device disclosed in Japanese Patent No. 4243684, the operation state detection unit 103 obtains peaks of peaks and valleys of acceleration components in the vertical direction.

  FIG. 8 is a diagram illustrating waveforms of acceleration components in the vertical direction when the sitting operation and the standing operation are performed. As shown in FIG. 8, in the case of the seating operation, the interval from the peak of the peak of the acceleration component in the vertical direction to the peak of the valley is about 0.5 seconds. On the other hand, in the standing motion, the interval from the peak of the vertical acceleration component to the peak of the peak is about 0.5 seconds. For this reason, the operation state detection unit 103 determines whether the person is in a sitting state or a standing state based on the interval between the peaks. That is, when the interval from the peak of the peak of the acceleration component in the vertical direction to the peak of the valley is within a predetermined range from 0.5 seconds, the motion state detection unit 103 determines that the human motion state is the sitting state. judge. Further, when the interval between the peak of the vertical acceleration component valley and the peak of the mountain is within a predetermined range from 0.5 seconds, the motion state detection unit 103 determines that the human motion state is the standing state. judge.

  As described above, when the motion state detection unit 103 determines whether the human motion state is the standing state or the seated state, the position in the height direction of the human is approximately 50 cm or less (more specifically, approximately 40 cm or less). It means that it was detected with the accuracy of.

  Further, as in the example shown in FIG. 3, a smartphone 300 equipped with information devices for detecting human motion such as an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor is worn on the waist, and further, the acceleration sensor, the angular velocity sensor, and the geomagnetism are mounted. When a small headset-type sensor group 301 including sensors is mounted on the head, the operation state detection unit 103 can further detect the following human postures and movements.

  FIG. 9 is a diagram showing waveforms of angular velocity components in the horizontal direction when the squatting operation and the standing operation are performed. From the acceleration data from the acceleration sensor, waveforms similar to those of the seating motion and the standing motion shown in FIG. 8 are detected, but it is difficult to discriminate the squatting motion and the standing motion only from the acceleration data.

  For this reason, the motion state detection unit 103 uses the above-described method for discriminating between the sitting motion and the standing motion based on the waveform of FIG. 8, and the temporal change in the angular velocity data in the horizontal direction received from the angular velocity sensor becomes the waveform of FIG. By judging whether or not they match, a squatting action and a standing action are discriminated.

  Specifically, the operation state detection unit 103 first has an interval from the peak of the vertical acceleration component to the peak of the valley based on the acceleration vector received from the acceleration sensor within a predetermined range from 0.5 seconds. Determine whether or not.

  When the interval from the peak of the peak of the acceleration component in the vertical direction to the peak of the valley is within a predetermined range from 0.5 seconds, the motion state detection unit 103 detects the horizontal direction of the angular velocity vector received from the angular velocity sensor. As shown in the waveform of FIG. 9, the angular velocity component of gradually increases from 0, then reaches a peak of the mountain with a rapid increase, gradually decreases from the peak of the mountain, then gradually returns to 0, and the time between Is about 2 seconds, it is determined that the human action is a squatting action.

  In addition, the operation state detection unit 103 determines whether or not the interval from the peak of the valley of the acceleration component in the vertical direction to the peak of the peak is within a predetermined range from 0.5 seconds. When the interval from the peak of the valley of the acceleration component in the vertical direction to the peak of the mountain is within a predetermined range from 0.5 seconds, the motion state detection unit 103 performs the horizontal direction of the angular velocity vector received from the angular velocity sensor. When the angular velocity component of the peak reaches the valley peak stepwise from 0, gradually returns to 0 from the valley peak, and the time between them is about 1.5 seconds, as shown in the waveform of FIG. It is determined that the human motion is a standing motion.

  As the angular velocity vector used in the determination of the squatting motion and the standing motion in the motion state detection unit 103 as described above, it is preferable to use an angular velocity vector received from an angular velocity sensor mounted on the head. This is because the angular velocity component in the horizontal direction based on the angular velocity vector from the angular velocity sensor worn on the head shows the waveform shown in FIG.

  FIG. 10 is a diagram illustrating a waveform of an angular velocity component in the vertical direction when a human performs an operation of changing the direction by approximately 90 degrees in a stationary state. If the angular velocity component in the vertical direction is positive, the direction is changed to the right side, and if it is negative, the direction is changed to the left side.

  The operation state detection unit 103 gradually changes the angular velocity component in the vertical direction of the angular velocity vector received from the angular velocity sensor from 0 to gradually reaching the peak of the mountain as shown in FIG. When it returns and the time between these is about 3 seconds, it determines with the operation | movement changing a direction to the right.

  Further, the operation state detection unit 103 gradually returns to 0 after the time-dependent change in the angular velocity component in the vertical direction reaches the peak of the valley gradually from 0 as shown in the waveform of FIG. Is about 1.5 seconds, it is determined that the direction changes to the left.

  The motion state detection unit 103 is similar to the waveform of FIG. 10 according to the above-described determination in terms of the vertical angular velocity component of the angular velocity vector received from both the angular velocity sensor of the head and the angular velocity sensor of the hip smartphone 300. When the change over time is indicated, it is determined that the movement of the whole body changes to the right or left.

  On the other hand, the motion state detection unit 103 shows that the vertical angular velocity component of the angular velocity vector received from the angular velocity sensor of the head shows a temporal change similar to the waveform of FIG. When the angular velocity component in the vertical direction of the angular velocity vector from the angular velocity sensor shows a temporal change that is completely different from the waveform of FIG. 10, it is determined that the direction of the head is changed to the right or left. As such an operation, for example, a posture operation in the case of communicating with an adjacent user while the user is seated can be considered.

  FIG. 11 is a diagram showing the waveform of the angular velocity component in the horizontal direction of the angular velocity vector received from the angular velocity sensor of the head when the line of sight is removed from the display in the sitting state.

  Consider a case where the position specifying unit 102 determines that the absolute position of a person is in front of a desk, and the operation state detecting unit 103 detects that a person in front of the desk is in a sitting state. In such a case, the motion state detection unit 103 gradually reduces the angular velocity component in the horizontal direction of the angular velocity vector received from the angular velocity sensor of the human head from 0 like the waveform shown in FIG. And then suddenly returns to 0, and the time between them is about 1 second, it is determined that the action is to remove the line of sight from the display in the seated state (the action to look up). Further, the operation state detection unit 103 reaches the peak of the mountain while the angular velocity component in the horizontal direction gradually increases from 0 as in the waveform shown in FIG. 11, and then gradually returns to 0. When the time is about 1.5 seconds, it is determined that the operation is to return the line of sight to the display from the state where the line of sight is removed from the display in the sitting state.

  FIG. 12 is a diagram showing the waveform of the angular velocity component in the horizontal direction of the angular velocity vector received from the angular velocity sensor of the head when the line of sight is removed from the display in the sitting state.

  Consider a case where the position specifying unit 102 determines that the absolute position of a person is in front of a desk, and the operation state detecting unit 103 detects that a person in front of the desk is in a sitting state. In such a case, the motion state detection unit 103 causes the angular velocity component in the horizontal direction of the angular velocity vector received from the angular velocity sensor of the human head to rapidly increase from 0 as shown in the waveform shown in FIG. If it returns to 0 rapidly after that, and the time between them is about 0.5 seconds, it is determined that the action is to take the line of sight down from the display in the seated state (looking down) .

  Further, the operation state detection unit 103 reaches the peak of the valley while the angular velocity component in the horizontal direction decreases rapidly from 0 as in the waveform shown in FIG. 12, and then suddenly returns to 0. When the time is about 1 second, it is determined that the operation is to return the line of sight to the display from the state where the line of sight is removed from the display in the sitting state.

  As described above, the motion state detection unit 103 is a posture and motion that an office worker can take on a daily basis, that is, walking (standing state), standing (stationary state), sitting on a chair, squatting during work, sitting state Alternatively, it is possible to determine by the above-described method whether the direction (direction) is changed in the standing state, looking up at the heaven in the sitting state or the standing state, whispering in the sitting state or the standing state, and the like.

  In addition, when using the technique of the dead reckoning device of patent 4243684, as disclosed in patent 4243684, the lifting and lowering motion of a human by an elevator is also determined using the acceleration component in the vertical direction. .

  For this reason, in the present embodiment, the operation state detection unit 103 uses the function of the map matching device disclosed in Japanese Patent Application Laid-Open No. 2009-14713, and the vertical acceleration component in FIG. When the detected waveform is detected, it is possible to determine with high accuracy whether it is a standing motion or a seating motion, unlike the elevator lifting / lowering motion of the dead reckoning device disclosed in Japanese Patent No. 4243684.

  The correction unit 104 corrects the specified absolute position and operation status (direction and posture) based on the captured image from the monitoring camera 400 and the map data stored in the storage unit 110. More specifically, the correction unit 104 determines whether or not the absolute position, direction, and posture of the human determined as described above are correct by image analysis of a captured image of the monitoring camera 400 or the like, And the function of the map matching device disclosed in Japanese Patent Application Laid-Open No. 2009-14713. If it is incorrect, the correction unit 104 corrects the correct absolute position, direction, and orientation obtained from the captured image and the map matching function.

  The correction unit 104 is configured to perform correction using limited means such as short-range wireless and optical communication such as RFID and Bluetooth (registered trademark) as well as a captured image from the monitoring camera 400. Also good.

  In this embodiment, the same technology as the dead reckoning device disclosed in Japanese Patent No. 4243684 and Japanese Patent Application Laid-Open No. 2011-47950, and the same technology as the map matching device disclosed in Japanese Patent Application Laid-Open No. 2009-14713. Is used to detect a human motion state, a relative movement vector from a reference position, and a posture (whether standing or sitting), but the detection method is not limited to these techniques. Further, in the above description, when it is determined that the human movement state is stationary, the human position is identified and the movement state such as direction and posture is detected. Similarly, when the is in a walking state, the absolute position in the room of the person may be specified and the operation status such as the direction and the posture may be detected.

  In addition, as a technique capable of detecting a human position, in addition to the method described above performed by the positioning server device 100 based on detection data of an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor, for example, entrance / exit management using an IC card or the like , Human detection by a human sensor, a method using a wireless LAN, a method using an indoor GPS (IMES), a method for processing an image captured by a camera, a method using an active RFID, and visible light communication Methods are known.

  In the entrance / exit management using an IC card or the like, personal identification is possible, but the positioning accuracy is extremely low for the entire management target area. Therefore, although it is possible to know who is in the area, it is not possible to grasp the human activity status in the area.

  Human detection by a human sensor can obtain a positioning accuracy of about 1 to 2 m which is a detection range of the human sensor, but individual identification cannot be performed. In addition, in order to grasp the human activity state in the area, it is necessary to disperse and arrange a large number of human sensors in the area.

  In the method using a wireless LAN, the distance between one wireless LAN terminal possessed by a human and a plurality of LAN access points installed in the area is measured, and the position of the human in the area is determined by the principle of triangulation. Is identified. Although this method enables individual identification, the positioning accuracy is highly dependent on the environment, and the positioning accuracy is generally as low as 3 m or more.

  In the method using indoor GPS, a dedicated transmitter that emits radio waves in the same frequency band as GPS satellites is installed indoors. Send. Then, the signal is received by a receiving terminal possessed by an indoor person, thereby specifying the position of the person inside. Although this method can identify individuals, the positioning accuracy is as low as about 3 to 5 m. In addition, it is necessary to install a dedicated transmitter, which increases the introduction cost.

  Although the method for image processing of the captured image of the camera can obtain a relatively high positioning accuracy of about several tens of centimeters, it is difficult to perform individual identification. For this reason, in the positioning server device 100 of this embodiment, the captured image of the monitoring camera 400 is used only when correcting the absolute position, direction, and posture of the employee.

  In the method using active RFID, a person has an RFID tag with a built-in battery, and the position of the person is specified by reading information of the RFID tag with a tag reader. Although this method enables individual identification, the positioning accuracy is highly dependent on the environment, and the positioning accuracy is generally as low as 3 m or more.

  The method using visible light communication enables individual identification and relatively high positioning accuracy of about several tens of centimeters. However, humans cannot be detected in places where the visible light is blocked, and natural light and other Since there are many noise sources and interference sources such as visible light, it is difficult to maintain the stability of detection accuracy.

  In contrast to these technologies, the method performed by the positioning server device 100 according to the present embodiment is capable of individual identification, and obtains high positioning accuracy equivalent to a human shoulder width or stride. , Can detect human operating situation. Specifically, according to the method performed by the positioning server device 100 according to the present embodiment, the posture and motion that an office employee can take on a daily basis, that is, walking (standing state) or standing up as a human operating state. (Stationary state), sitting on a chair, squatting during work, changing direction (direction) when sitting or standing, looking up to the heavens when sitting or standing, and detecting whispering while sitting or standing it can.

  For this reason, in this embodiment, the positioning server device 100 uses the above-described method based on the detection data of the acceleration sensor, the angular velocity sensor, and the geomagnetic sensor of the smartphone 300 and the sensor group 301, and the employee in the office that is the control target area. The absolute position of the worker and the operation status of the employee are detected. However, the method for detecting the absolute position of the employee in the office, which is the control target area, and the operation status of the employee is not limited to the method described above performed by the positioning server device 100. One or more of the other methods described above may be used in the above-described method performed by the positioning server device 100. The absolute position and the operation status of the employee may be detected by a combination of one or more methods. May be combined to detect the absolute position and operational status of the employee.

  Next, details of the control server device 200 will be described. The control server device 200 includes a plurality of LED lighting devices 500, a plurality of taps 600, and a plurality of air conditioners installed in the room based on the position and operation state (direction, posture) of the person in the room that is the control target area. Each of the 700s is remotely controlled via a network. In addition, the control server device 200 has a function as an automatic registration device of the present embodiment.

  FIG. 13 is a block diagram illustrating a functional configuration of the control server device 200 according to the present embodiment. As illustrated in FIG. 13, the control server device 200 according to the present embodiment corresponds to a communication unit 201, a power consumption management unit 202, a device control unit 210, a first determination unit 231, and a second determination unit 232. An attachment unit 233, an output unit 234, and a storage unit 220 are mainly provided.

  The storage unit 220 is a storage medium such as an HDD or a memory, and stores various kinds of information necessary for processing of the positioning server device 100 such as position data of a room that is a control target area. In addition, the storage unit 220 stores information on the result of association between the person and the tap 600 by the association unit 233 described later, that is, registration information indicating the correspondence between the person and the tap 600.

  The communication unit 201 receives the absolute position and motion information (direction, posture) of the person from the positioning server device 100. Further, the communication unit 201 receives power consumption from the plurality of LED lighting devices 500, the electric devices connected to the plurality of taps 600, and the plurality of air conditioners 700. In addition, the communication unit 201 transmits a control signal for performing power control to the plurality of LED lighting devices 500, the plurality of taps 600, and the plurality of air conditioners 700. The power consumption acquisition (reception) method by the communication unit 201 may be any method as long as the power consumption consumed by each electrical device (including the LED lighting device 500 and the air conditioner 700) can be acquired in time series. . For example, as described above, the tap 600 has a function of measuring and transmitting the power consumption of the electrical device connected to the tap 600. Therefore, the communication unit 201 can acquire the power consumption of the electrical device connected to the tap 600 from the tap 600.

  The power consumption management unit 202 manages the power consumption received from the plurality of LED lighting devices 500, the electric devices connected to the plurality of taps 600, and the plurality of air conditioners 700. For example, the power consumption management unit 202 stores the power consumption acquired in time series in the storage unit 220 or the like by distinguishing each device.

  The device control unit 210 includes a lighting device control unit 211, an outlet control unit 213, and an air conditioner control unit 215. The lighting device control unit 211 controls the LED lighting device 500 based on the absolute position and motion information (direction, posture) of the person. More specifically, the lighting device control unit 211 sets the lighting range to be narrower than a predetermined range if the person is seated on the LED lighting device 500 disposed in the vicinity of the received absolute position, A control signal for setting the illuminance higher than a predetermined threshold is transmitted via the communication unit 201. As a result, it is possible to control the illumination range and illuminance suitable for fine work for a user who is working in a sitting state.

  On the other hand, the lighting device control unit 211 communicates a control signal for setting the illumination range wider than the predetermined range and setting the illuminance lower than the predetermined threshold if the person is standing up to the LED lighting device 500. The data is transmitted via the unit 201. This makes it possible to control the illumination range and illuminance so that a standing user can look over the entire room.

  The outlet control unit 213 controls power on / off of the tap opening of the tap 600 based on the absolute position of the person and the operation information (direction and posture). More specifically, the outlet control unit 213 is, for example, that a person is seated with respect to the display device connected to the tap 600 arranged in the vicinity of the received absolute position, and the direction with respect to the display device is forward. In the case of, the control signal for turning on the switch of the tap port to which the display device is connected in the tap 600 is transmitted via the communication unit 201.

  On the other hand, the outlet control unit 213 is connected to the display device connected to the tap 600 when a person is standing or the direction toward the display device is backward. A control signal for turning off the switch of the tap opening is transmitted via the communication unit 201.

  As described above, the power control is performed according to the direction of the person with respect to the display device, and the display device is an important device in the direct relationship with the person, and it is determined that the display device is used when the direction is forward. Because it can be done. Further, when the human posture is also in the sitting state, it can be determined that the display device is being used. As described above, in the present embodiment, power control is performed in consideration of the actual use of the device, and finer control can be performed as compared with the case where the power control is simply performed based on the distance from the device. It becomes.

  Furthermore, the outlet control unit 213 according to the present embodiment can perform power control of electrical devices such as a desktop PC main body and a display device in conjunction with human personal recognition information. For example, the personal authentication information is transmitted from the smartphone 300 possessed by a person in the room to the positioning server device 100 and transmitted from the positioning server device 100 to the control server device 200. Using the personal authentication information, the outlet control unit 213 can perform power control on an electrical device associated with each person in the room. The correspondence relationship between each person and the electrical device may be stored in the storage unit 220 as a part of the registration information described above, for example.

  The air conditioner control unit 215 controls on / off of the power supply of the air conditioner 700 based on the absolute position of the person. More specifically, the air conditioner control unit 215 transmits, via the communication unit 201, a control signal for turning on the power of the air conditioner 700 set in the group in which the received seat at the absolute position exists.

  The first determination unit 231 determines whether or not a person in the room that is the control target area is in a predetermined specific state. In the present embodiment, for example, it is effective to set a stationary state, which is a state where a human has stopped walking, as a specific state. In this case, the first determination unit 231 determines whether or not a person in a walking state is in a stationary state, and determines whether or not the person in a walking state is in a stationary state. Then, when the first determination unit 231 detects a person who has entered a stationary state, the first determination unit 231 detects information indicating that the person has entered a stationary state (the time when the person has entered a stationary state if necessary) and the person who has entered the stationary state. Information to be specified (personal authentication information) is notified to the associating unit 233.

  In the present embodiment, for example, it is also effective to set a seating state in which a person is sitting on a chair as a specific state. In this case, the first determination unit 231 determines whether or not a person who is in a walking state indoors is a target of determination and whether or not the person in the walking state is in a sitting state. And if the 1st determination part 231 detects the person who became the seated state, the information (the time when it became seated if necessary) and the person who became the seated state will be detected. Information to be specified (personal authentication information) is notified to the associating unit 233.

  For example, the first determination unit 231 can be configured to determine whether or not a person in the room, which is the control target area, has entered a specific state based on detection result data acquired from the positioning server device 100. The first determination unit 231 acquires detection data (at least one of an acceleration vector, an angular velocity vector, and a magnetic orientation vector) from the smartphone 300 possessed by a person in the room, and the control server device 200 based on the detection data. The human motion may be detected by a method similar to that described above, and it may be determined whether or not the indoor human has entered a specific state. In addition, the first determination unit 231 acquires a captured image captured by the monitoring camera 400 directly or via the positioning server device 100, analyzes the captured image, and determines whether or not a person in the room is in a specific state. You may comprise so that it may determine.

  The second determination unit 232 determines whether or not the power consumption of the electrical device connected to the tap 600 has changed. As described above, the power consumption of the electrical device connected to the tap 600 is acquired from the tap 600 in time series by the communication unit 201. The second determination unit 232 monitors the power consumption acquired in this time series, and determines whether or not the power consumption of the electrical device connected to the tap 600 has changed. Then, the second determination unit 232 includes information indicating that the power consumption of the electrical device has changed (time when the power consumption has changed if necessary) and information for identifying the tap 600 to which the electrical device is connected. The association unit 233 is notified.

  In the present embodiment, for example, the second determination unit 232 determines whether or not the power consumption of the electrical device connected to the tap 600 has changed by a predetermined change amount as the change amount associated with the activation of the electrical device. It is desirable to be configured to determine. The second determination unit 232, for example, for an electric device having a normal operation mode and a low power mode with low power consumption such as a desktop PC, the power consumption of the electric device is changed from the low power mode. It may be configured to determine whether or not a change amount determined in advance as a change amount associated with the return to the normal operation mode has changed.

  The association unit 233 associates the person with the tap 600 based on the determination result of the first determination unit 231 and the determination result of the second determination unit 232. That is, when the power consumption of the electrical device changes after the person enters the specific state, the associating unit 233 associates the person in the specific state with the tap 600 to which the electrical device whose power consumption has changed is connected. .

  In the present embodiment, one tap 600 is provided on each desk where a person works in a room. These taps 600 are exclusively used by persons who work with their corresponding desks as their seats. A person who works in his / her seat generally moves in the room, stops in front of his / her seat, sits in his / her seat, and then works by activating an electrical device such as a desktop PC connected to the tap 600. Therefore, when the power consumption of an electrical device changes after a person enters a stationary state or a seated state, the electrical device is connected to a tap 600 that is exclusively used by the person in the stationary state or the seated state. There is a high possibility that it is a device. In the present embodiment, based on such a tendency, for example, a stationary state or a seating state is determined as the specific state, and the associating unit 233 is connected to an electrical device whose power consumption has changed after the person enters the specific state. The tap 600 is associated with a human being in a specific state. Then, the associating unit 233 causes the storage unit 220 to store the result of associating the person with the tap 600 as registration information representing the correspondence between the person and the tap 600. Thereby, automatic registration of the correspondence between the tap 600 and the person using the tap 600 can be realized. Details of a specific example of processing by the associating unit 233 will be described later.

  The output unit 234 outputs registration information stored in the storage unit 220 in accordance with a user operation using the control server device 200 or a user operation of an external device that has accessed the control server device 200. Here, the output includes, for example, display on a display, data transmission to an external terminal, print output, and the like. When the output unit 234 outputs the registration information, it is possible to confirm the correspondence between the tap 600 automatically registered in the control server device 200 and a human.

  Next, the detection process by the positioning server device 100 of the present embodiment configured as described above will be described. FIG. 14 is a flowchart illustrating the procedure of the detection process performed by the positioning server device 100 according to the present embodiment. The detection process according to the flowchart is executed for each of the plurality of smartphones 300.

  In addition to the detection process according to this flowchart, the positioning server device 100 includes an acceleration sensor, an angular velocity sensor, a geomagnetic sensor, or an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor mounted on the plurality of smartphones 300. Detection data (acceleration vector, angular velocity vector, magnetic direction vector) is received from each sensor at regular intervals, and captured images are received from a plurality of monitoring cameras 400.

  First, it is determined whether or not a person has entered a room, which is a control target area, based on a captured image of a door to be opened and closed (step S11). If the user has not entered the room (step S11: No), the positioning server device 100 determines whether or not the person has left the room (step S20). If the user has not left the room (step S20: No), the process returns to step S11 and is repeated. If the user leaves the room (step S20: Yes), the detection process is terminated. When the user enters the room (step S11: Yes), the operation state detection unit 103 detects the operation state of the person who has entered the room using the method described above (step S12). Then, the operation state detection unit 103 determines whether or not the human operation state is a walking state (step S13), and repeats detection of the operation state while it is a walking state (step S13: Yes).

  On the other hand, when the human motion state is not the walking state in step S13 (step S13: No), the motion state detection unit 103 determines that the human motion state is the stationary state. And the position specific | specification part 102 calculates a relative movement vector from a door by the above-mentioned method by making a reference | standard position into a door (step S14).

  Then, the position specifying unit 102 specifies the absolute position of the human being in a stationary state based on the map data of the room stored in the storage unit 110 and the relative movement vector from the door (step S15). As a result, the position specifying unit 102 can specify up to which desk the person is placed in the room, and as a result, the shoulder width of the person (approximately 60 cm or less, more specifically approximately 40 cm or less). The position of the person is specified with the accuracy of.

  Next, the operation state detection unit 103 further detects the direction (orientation) of the human display device from the magnetic direction vector received from the geomagnetic sensor as the operation state of the human being in a stationary state (step S16).

  Next, the motion state detection unit 103 detects the posture of whether the human body is sitting or standing by the above-described method (step S17). As a result, the operation state detection unit 103 detects the position in the height direction of the human with an accuracy of approximately 50 cm or less (more specifically, approximately 40 cm or less).

  In addition, the operation state detection unit 103 may determine whether the human operation state is a squatting operation or a standing operation, an operation for changing the orientation in the sitting state, an operation for returning the direction, an operation for raising the line of sight in the sitting state, or an operation for returning the line of sight. Whether the action of lowering the line of sight or the action of returning the line of sight may be detected.

  Next, the correction unit 104 determines whether or not correction is necessary for the specified absolute position, detected direction, and posture as described above, and corrects if necessary (step S18).

  Then, the communication unit 101 transmits the absolute position, the detected direction and orientation (if corrected, the corrected absolute position, the detected direction and orientation) to the control server device 200 as detection result data. (Step S19). In the above description, when it is determined that a human motion state is stationary, the absolute position, direction, and posture of the human being are transmitted to the control server device 200 as detection result data. Similarly, when the motion state is the walking state, the absolute position, direction, and posture of the person may be transmitted to the control server device 200 as detection result data.

  Next, device control processing by the control server device 200 will be described. FIG. 15 is a flowchart illustrating a procedure of device control processing according to the present embodiment.

  First, the communication unit 201 receives the absolute position, direction, and posture of a person as detection result data from the positioning server device 100 (step S31). Next, each control unit 211, 213, 215 of the device control unit 210 specifies the LED lighting device 500, the tap 600, and the air conditioner 700 to be controlled from the absolute position of the received detection result data (step S32).

  More specifically, the lighting device control unit 211 refers to the position data stored in the storage unit 220 and specifies the LED lighting device 500 installed on the desk corresponding to the absolute position as a control target. Further, the outlet control unit 213 refers to the position data stored in the storage unit 220 and specifies the tap 600 installed near the desk corresponding to the absolute position as a control target. The air conditioner control unit 215 refers to the position data stored in the storage unit 220 and specifies the air conditioner 700 installed corresponding to a group having a desk corresponding to the absolute position as a control target.

  Next, the air conditioner control unit 215 performs control to turn on the power of the identified air conditioner 700 (step S33).

  Next, the outlet control unit 213 determines whether or not the direction of the received detection result data is forward and whether or not the posture of the detection result data is a seated state (step S34). When the direction is the front and the posture is the seating state (step S34: Yes), the outlet control unit 213 switches the switch of the tap mouth to which the display device is connected in the tap 600 specified in step S32. Control to turn on is performed (step S35).

  On the other hand, when the direction is rearward or the posture is standing in step S34 (step S34: No), the outlet control unit 213 connects the display device at the tap 600 specified in step S32. Control is performed to turn off the switch of the tapped port (step S36).

  Next, the lighting device control unit 211 determines again whether or not the posture of the received detection result data is the seating state (step S37). When the posture is the seated state (step S37: Yes), the lighting device control unit 211 sets the illumination range of the LED lighting device 500 specified in step S32 to be narrower than the predetermined range, and sets the illuminance to a predetermined threshold value. Control to set higher is performed (step S38).

  On the other hand, when the posture is in the standing state in step S37 (step S37: No), the illumination device control unit 211 sets the illumination range of the LED illumination device 500 specified in step S32 to be wider than the predetermined range, and the illuminance Is set to be lower than a predetermined threshold value (step S39).

  In addition, you may comprise each control part 211,213,215 of the apparatus control part 210 so that control other than the control mentioned above may be performed with respect to each control object apparatus.

  In addition, the human movement status is squatting or standing, changing the orientation in the sitting state, returning it, raising the line of sight in the sitting state (looking up), returning the line of sight, or looking in the sitting state. The control units 211, 213, and 215 of the device control unit 210 may be configured to control each control target device depending on whether the operation is to lower (look down) or return the eye.

  Examples of each operation, control target device and control method in such a case are as follows. These operations are operations that can occur when it is assumed that an operator is sitting in front of a desk, and the controlled device is a desktop fan corresponding to a PC or a display device of a PC, a desk lamp, and individual air conditioning. Etc.

  For example, when it is determined that the operation of squatting continues for a certain time or more from the received detection result data when the worker is at the desk, the switch of the tap port to which the power source of the PC is connected is turned off. Thus, the outlet control unit 213 can be configured. In addition, the mode control unit can be configured so that the device control unit 210 is provided with a mode control unit that controls the mode of the device, and the display device of the PC is shifted to the standby mode.

  In addition, when the standing operation is detected from the sitting state and the standing state continues for a certain time or more, the mode control unit is configured to shift the PC to the standby mode, or the power supply of the display device is connected at the same time. The outlet control unit 213 can be configured to turn off the switch of the tapped port.

  The following control is given as an example for the operation of changing the direction. If a change in the orientation of the face or upper body is detected from the state of sitting at the desk, and this state continues for a certain period of time, the situation may be such as a conversation with another worker in an adjacent seat. If the lighting device such as a PC, a display device, or a desk lamp is set to standby or off, and it is detected that the orientation of the worker has returned to the original state, the lighting device such as a PC, a display device, or a desk lamp is turned on. The outlet control unit 213 and the mode control unit can be configured so as to be turned on.

  Further, it is conceivable to perform an operation of looking down when the worker reads a document at a desk, and to perform an operation of looking up at the ceiling when the worker comes up with or thinks of an idea. For this reason, when an operation of looking up or looking down for a certain time or longer is continuously detected, the outlet control unit 213 performs control to shift the PC to the standby mode or to turn off the display device. A mode control unit can be configured. Further, in the case of an operation to look down, the outlet control unit 213 may be configured to perform control without turning off the desk lamp.

  As described above, in the present embodiment, the position of the person is specified with the accuracy of the shoulder width, the direction and posture of the person is detected, and the power control of the equipment is performed. Therefore, the power control of the equipment with finer precision is possible. Thus, it is possible to realize further power saving and energy saving while maintaining worker comfort and high work efficiency.

  In other words, in this embodiment, not only can a person be detected, but the equipment owned by the person, the lighting equipment directly above the desk on which the person sits, the air conditioner, and the office equipment can be individually controlled, and each person can be controlled. It is possible to simultaneously grasp the amount of power used.

  In the prior art, even if the power of buildings, offices, factories, and offices can be realized so-called "visualization", it is unclear how individuals can save power, and the overall target value If the situation is not tight, such as exceeding the power supply amount or exceeding the amount of power supplied, it is difficult to proceed continuously because it is difficult to be aware of power savings. It is possible to realize further power saving and energy saving while maintaining efficiency.

  Further, according to the present embodiment, even in automatic device control, power saving can be further improved by performing cooperative control between devices as well as people and devices.

  Next, a specific example of a method in which the associating unit 233 of the control server device 200 associates the person with the tap 600 will be described in detail.

(First method)
The first method is an example of associating the tap 600 to which the electric device whose power consumption has changed first after the person enters the specific state is connected to the person who has entered the specific state. In this method, the processing of the associating unit 233 is extremely simple, but the accuracy of the associating is poor in a scene where a large number of people activate their electric devices toward their seats in the same time zone. For this reason, the first method is particularly effective in an environment where it is assumed that a relatively small number of people start up electrical devices in different time zones.

  FIG. 16 is a diagram for explaining the association between the person and the tap 600 according to the first method. In the first method, as shown in FIG. 16, after it is determined by the first determination unit 231 that the person has entered a specific state at time Tw, the power consumption of the electrical device is first determined by the second determination unit 232 at time Tq. Is determined to have changed, the associating unit 233 associates the person who has entered the specific state at time Tw with the tap 600 to which the electrical device whose power consumption has changed at time Tq is connected. The correspondence between the associated person and the tap 600 is stored in the storage unit 220 as registration information, and is excluded from processing by the subsequent association unit 233.

  FIG. 17 is a flowchart illustrating a processing procedure according to the first method. First, the associating unit 233 monitors the notification from the first determination unit 231 and receives a notification from the first determination unit 231 as to whether or not the person has entered a specific state, that is, a notification that the person has entered the specific state. It is determined whether or not it has arrived (step S101). Then, the associating unit 233 repeats the process of step S101 while the first determination unit 231 does not receive a notification that a person has entered a specific state (step S101: No). On the other hand, upon receiving a notification that the person has entered the specific state (step S101: Yes), the associating unit 233 next monitors the notification from the second determining unit 232, and the power consumption of the electrical device changes. It is determined whether or not a notification that the power consumption of the electrical device has changed is received from the second determination unit 232 (step S102). Then, the association unit 233 repeats the process of step S102 while the second determination unit 232 has not received a notification that the power consumption of the electrical device has changed (No in step S102). On the other hand, upon receiving a notification that the power consumption of the electrical device has changed (step S102: Yes), the associating unit 233 selects the tap 600 to which the electrical device whose power consumption has changed in step S102 is connected in step S101. In association with the person in the specific state, the correspondence is stored as registration information in the storage unit 220 (step S103).

  As described above, in the first method, the tap 600 to which the electrical device that has changed in power consumption first after the person enters the specific state is associated with the person in the specific state. In the process, automatic registration of the correspondence between the tap 600 and the person using the tap 600 can be realized.

(Second method)
In the second method, a tap 600 to which an electrical device having a change in power consumption is connected for the first time after a predetermined time elapses from the time when the human enters the specific state is connected to the human who enters the specific state. This is an example of association. In other words, in the first method, the tap 600 connected to the electric device that first changed in power consumption after the person entered the specific state is associated with the person in the specific state. Then, when the power consumption of the electrical device has changed between the time when the human has entered the specific state and the elapse of a predetermined time, the tap 600 to which the electrical device having the first change in power consumption is connected, Correspond to a person in a specific state. The predetermined time may be determined, for example, by adding a predetermined margin to the average time from when a person reaches his / her seat until the electric device such as the desktop PC of his / her seat is activated.

  FIG. 18 is a diagram for explaining the association between the person and the tap 600 according to the second method. In the second method, as shown in FIG. 18A, after the first determination unit 231 determines that the person has entered a specific state at time Tw, the second determination unit 232 first performs electrical equipment at time Tq. If the time Tq is earlier than the time Tw + S when the predetermined time S has elapsed from the time Tw when it is determined that the power consumption has changed, the associating unit 233 determines that the human being in the specific state at the time Tw The tap 600 to which the electrical device whose power consumption has changed at time Tq is connected is associated. On the other hand, as shown in FIG. 18B, after the first determination unit 231 determines that the person has entered the specific state at time Tw, the second determination unit 232 first determines the power consumption of the electrical device at time Tq. If it is determined that the time Tq is later than the time Tw + S when it is determined that the change has occurred, the associating unit 233 connects the person who has entered the specific state at the time Tw and the electric device whose power consumption has changed at the time Tq. The association with the performed tap 600 is not performed, and the association is put on hold. The correspondence between the associated person and the tap 600 is stored in the storage unit 220 as registration information, and is excluded from processing by the subsequent association unit 233. On the other hand, the person who has been put on hold and the tap 600 are subjected to processing by the corresponding unit 233 thereafter.

  FIG. 19 is a flowchart illustrating a processing procedure according to the second method. First, the associating unit 233 monitors the notification from the first determination unit 231 and receives a notification from the first determination unit 231 as to whether or not the person has entered a specific state, that is, a notification that the person has entered the specific state. It is determined whether or not it has arrived (step S201). Then, the associating unit 233 repeats the process of step S201 while the first determination unit 231 does not receive a notification that the person has entered a specific state (step S201: No). On the other hand, upon receiving a notification that the person has entered a specific state (step S201: Yes), the associating unit 233 starts a timer that counts a predetermined time (step S202).

  Next, the associating unit 233 monitors the timer and the notification from the second determining unit 232, and whether the power consumption of the electrical device has changed before a predetermined time has elapsed since the time when the human entered a specific state. It is determined whether or not (steps S203 and S204). That is, the associating unit 233 checks the count of the timer started in step S202 to determine whether or not a predetermined time has elapsed (step S203). If the predetermined time has not elapsed (step S203: No) ), It is determined whether or not a notification that the power consumption of the electrical device has changed has arrived from the second determination unit 232 (step S204). The associating unit 233 repeats the processing of step S203 and step S204 while the notification that the power consumption of the electrical device has changed has not arrived from the second determining unit 232 (step S204: No). When the predetermined time has elapsed without receiving a notification that the power consumption of the electrical device has changed from the determination unit 232 (step S203: Yes), the process ends. On the other hand, when the notification that the power consumption of the electrical device has changed before the predetermined time has elapsed (step S204: Yes), the associating unit 233 connects the electrical device whose power consumption has changed in step S204. The performed tap 600 is associated with the person who is in the specific state in step S201, and the correspondence is stored in the storage unit 220 as registration information (step S205).

  As described above, in the second method, the tap 600 to which the electrical device whose power consumption has changed for the first time from when the human enters the specific state until the predetermined time has elapsed is connected to the specific state. In order to associate with the person who has become, the accuracy of the association between the person and the tap 600 can be improved as compared with the first method.

(Third method)
The third method is to specify a tap 600 when there is only one tap 600 connected to an electric device whose power consumption has changed between the time when a human enters a specific state and a predetermined time elapses. This is an example of associating with a human being in a state. That is, in the second method, when the power consumption of the electrical device changes between the time when the person enters the specific state and the predetermined time elapses, the electrical device that first changed the power consumption is connected. In the third method, each tap 600 is connected to a plurality of taps 600 until a predetermined time elapses from the time when the person enters the specific state. When the power consumption of the plurality of electric devices changed, the association between the person and the tap 600 is put on hold.

  FIG. 20 is a diagram for explaining the association between the person and the tap 600 according to the third method. In the third method, as shown in FIG. 20A, after the first determination unit 231 determines that the person is in a specific state at the time Tw, the second determination unit 232 first performs the electrical device at the time Tq1. When it is determined that the power consumption has changed, the time Tq1 is before the time Tw + S when the predetermined time S has elapsed from the time Tw, and the electric device whose power consumption has changed before the time Tw + S is connected If the other tap 600 is not present, the associating unit 233 associates the person who is in the specific state at time Tw with the tap 600 to which the electrical device whose power consumption has changed at time Tq1 is connected. That is, even if the power consumption of the electrical device connected to another tap 600 other than the tap 600 to which the electrical device whose power consumption has changed at time Tq1 changes at time Tq2, time Tq2 is later than time Tw + S. Then, the person who is in the specific state at time Tw is associated with the tap 600 to which the electric device whose power consumption has changed at time Tq1 is connected.

  On the other hand, as shown in FIG. 20B, after the first determination unit 231 determines that the person has entered the specific state at time Tw, the second determination unit 232 first determines the power consumption of the electrical device at time Tq1. Even if the time Tq1 is before the time Tw + S when it is determined that it has changed, if the time Tq2 at which the power consumption of the electrical device connected to the other tap 600 has changed is before the time Tw + S, The association between the person who has entered the specific state at time Tw and the tap 600 connected to the electric device whose power consumption has changed at time Tq1 is not performed. The correspondence between the associated person and the tap 600 is stored in the storage unit 220 as registration information, and is excluded from processing by the subsequent association unit 233. On the other hand, the person who has been put on hold and the tap 600 are subjected to processing by the corresponding unit 233 thereafter.

  FIG. 21 is a flowchart showing a processing procedure according to the third method. First, the associating unit 233 monitors the notification from the first determination unit 231 and receives a notification from the first determination unit 231 as to whether or not the person has entered a specific state, that is, a notification that the person has entered the specific state. It is determined whether it has arrived (step S301). Then, the associating unit 233 repeats the process of step S301 while the first determining unit 231 does not receive a notification that the person has entered the specific state (step S301: No). On the other hand, when receiving a notification that the person has entered the specific state (step S301: Yes), the associating unit 233 starts a timer that counts a predetermined time (step S302).

  Next, the associating unit 233 monitors the timer and the notification from the second determining unit 232, and the power consumption of the electric device has changed before the predetermined time S has elapsed since the time when the human entered the specific state. Whether or not (steps S303 and S304). That is, the associating unit 233 confirms the count of the timer started in step S302 to determine whether or not a predetermined time has elapsed (step S303), and if the predetermined time has not elapsed (step S303: No) ), It is determined whether or not a notification that the power consumption of the electrical device has changed has arrived from the second determination unit 232 (step S304). Then, as long as the notification that the power consumption of the electric device has changed has not arrived from the second determination unit 232 (step S304: No), the associating unit 233 repeats the processing of step S303 and step S304, If a predetermined time has elapsed without receiving a notification that the power consumption of the device has changed (step S303: Yes), the processing is terminated.

  On the other hand, when the notification that the power consumption of the electrical device has changed is received before the predetermined time has elapsed (step S304: Yes), the associating unit 233 further receives a notification from the timer and the second determining unit 232. Whether or not the power consumption of the electrical device connected to another tap 600 other than the tap 600 connected to the electrical device whose power consumption has changed in step S304 has changed before the predetermined time has elapsed. Is determined (steps S305 and S306). That is, the associating unit 233 checks the count of the timer started in step S302 to determine whether a predetermined time has elapsed (step S305), and if the predetermined time has not elapsed (step S305: No) ), It is determined whether or not a notification that the power consumption of the electrical device connected to the other tap 600 has changed has arrived from the second determination unit 232 (step S306). Then, the associating unit 233 receives the notification that the power consumption of the electrical device connected to the other tap 600 has not changed from the second determining unit 232 (step S306: No), step S305 and step When the process of S306 is repeated and a notification that the power consumption of the electrical device connected to another tap 600 has changed before the predetermined time has elapsed (step S306: Yes), the process ends.

  On the other hand, when a predetermined time has elapsed without receiving a notification that the power consumption of the electrical device connected to another tap 600 has changed (step S305: Yes), the electrical device whose power consumption has changed in step S304. The connected tap 600 is associated with the person who has entered the specific state in step S301, and the correspondence is stored in the storage unit 220 as registration information (step S307).

  As described above, in the third method, when there is only one tap 600 to which an electric device whose power consumption has changed from the time when a human enters a specific state until a predetermined time has elapsed, Since the tap 600 is associated with the human being in the specific state, the accuracy of the association between the human and the tap 600 can be improved as compared with the second method.

(Fourth method)
According to the fourth method, when there are a plurality of persons who have entered a specific state before the power consumption of the electrical equipment has changed, the power consumption of the person who has finally entered the specific state among the plurality of persons has changed. This is an example of associating with a tap 600 to which an electrical device is connected. In the fourth method, when the power consumption of the electrical device changes, the time when the person enters the specific state is compared before the time when the person enters the specific state.

  FIG. 22 is a diagram illustrating the association between the person and the tap 600 according to the fourth method. In the fourth method, as shown in FIG. 22, at the time Tw1 and the time Tw2, it is determined by the first determination unit 231 that the person has entered a specific state, and then at the time Tq, the second determination unit 232 first When it is determined that the power consumption of the electrical device has changed, the associating unit 233 identifies the person who last entered the specific state before time Tq, that is, the person who finally entered the specific state, that is, the time Tw2. The person who has entered the state is associated with the tap 600 to which the electrical device whose power consumption has changed at time Tq is connected. The correspondence between the associated person and the tap 600 is stored in the storage unit 220 as registration information, and is excluded from processing by the subsequent association unit 233.

  FIG. 23 is a flowchart illustrating a processing procedure according to the fourth method. First, the associating unit 233 monitors the notification from the first determination unit 231 and receives a notification from the first determination unit 231 as to whether or not the person has entered a specific state, that is, a notification that the person has entered the specific state. It is determined whether it has arrived (step S401). When the association unit 233 receives notification from the first determination unit 231 that the person has entered the specific state (step S401: Yes), the association unit 233 temporarily stores the time when the person has entered the specific state (step S401: Yes). Step S402). On the other hand, if the notification that the person has entered the specific state has not arrived (step S401: No), the process of step S402 is not performed.

  Next, the associating unit 233 monitors the notification from the second determining unit 232, and the second notification is whether or not the power consumption of the electrical device has changed, that is, the power consumption of the electrical device has changed. It is determined whether it has arrived from the determination unit 232 (step S403). If the notification that the power consumption of the electrical device has changed has not arrived from the second determination unit 232 (step S403: No), the associating unit 233 returns to step S401 and repeats the subsequent processing. On the other hand, upon receiving a notification that the power consumption of the electrical device has changed (step S403: Yes), the associating unit 233 refers to the time temporarily stored in step S402, and among the humans in a specific state The person who finally entered the specific state is identified, the person is associated with the tap 600 connected to the electric device whose power consumption has changed, and the correspondence is stored in the storage unit 220 as registration information (step S40). S404).

  As described above, in the fourth method, the person who has finally entered the specific state before the power consumption of the electric device changes is associated with the tap 600 to which the electric device that has changed the power consumption is connected. Similar to the first method, automatic registration of the correspondence relationship between the tap 600 and the person using the tap 600 can be realized by extremely simple processing.

(Fifth method)
In the fifth method, the time when the last person who entered the specific state among the plurality of persons who entered the specific state before the power consumption of the electric device changed becomes the specific state. This is an example in which the person who has finally entered a specific state when the time after the time that has changed is a predetermined time later is associated with the tap 600 to which the electric device whose power consumption has changed is connected. That is, in the fourth method, among the plurality of persons who have entered the specific state before the power consumption of the electric device has changed, the person who has finally entered the specific state is connected to the electric device whose power consumption has changed. In the fifth method, when the time when the specific state was last reached is later than the time that is a predetermined time after the time when the power consumption of the electrical device has changed, The person who has finally entered the specific state is associated with the tap 600 to which the electric device whose power consumption has changed is connected. The predetermined time may be the same time as the predetermined time used in the second method or the third method, or may be a different time.

  FIG. 24 is a diagram for explaining the association between the person and the tap 600 according to the fifth method. In the fifth method, as shown in FIG. 24 (a), the first determination unit 231 determines that the person has entered a specific state at each of time Tw1 and time Tw2, and then the second determination unit 232 at time Tq. When it is first determined that the power consumption of the electrical device has changed, if the time Tw2 is later than the time Tq-S that is a predetermined time S later than the time Tq, the associating unit 233 specifies the time Tw2. The person who has entered the state is associated with the tap 600 to which the electrical device whose power consumption has changed at time Tq is connected.

  On the other hand, as shown in FIG. 24B, at the time Tw1 and the time Tw2, it is determined by the first determination unit 231 that the person has entered the specific state, and then at the time Tq, the second determination unit 232 first performs the electrical operation. When it is determined that the power consumption of the device has changed, if the time Tw2 is before the time Tq-S that is a predetermined time S backward from the time Tq, the associating unit 233 is in a specific state at the time Tw2. The association between the person and the tap 600 connected to the electric device whose power consumption has changed at time Tq is not performed, and the association is suspended. The correspondence between the associated person and the tap 600 is stored in the storage unit 220 as registration information, and is excluded from processing by the subsequent association unit 233. On the other hand, the person who has been put on hold and the tap 600 are subjected to processing by the corresponding unit 233 thereafter.

  FIG. 25 is a flowchart illustrating a processing procedure according to the fifth method. First, the associating unit 233 monitors the notification from the first determination unit 231 and receives a notification from the first determination unit 231 as to whether or not the person has entered a specific state, that is, a notification that the person has entered the specific state. It is determined whether it has arrived (step S501). When the association unit 233 receives notification from the first determination unit 231 that the person has entered the specific state (step S501: Yes), the association unit 233 temporarily stores the time when the person has entered the specific state (step S501: Yes). Step S502). On the other hand, if the notification that the person has entered the specific state has not arrived (step S501: No), the process of step S502 is not performed.

  Next, the associating unit 233 monitors the notification from the second determining unit 232, and the second notification is whether or not the power consumption of the electrical device has changed, that is, the power consumption of the electrical device has changed. It is determined whether or not it has arrived from the determination unit 232 (step S503). If the notification that the power consumption of the electric device has changed has not arrived from the second determination unit 232 (step S503: No), the associating unit 233 returns to step S501 and repeats the subsequent processing. On the other hand, upon receiving a notification that the power consumption of the electrical device has changed (step S503: Yes), the associating unit 233 temporarily stores the time when the power consumption of the electrical device has changed (step S504). Then, the associating unit 233 refers to the time temporarily stored in step S502, identifies the person who has finally entered the specific state among the persons who have entered the specific state, and the person enters the specific state. It is determined whether or not the current time is later than the time temporarily stored in step S504 and a predetermined time later than the time when the power consumption of the electrical device has changed (step S505).

  If the time at which the specific state was last reached is later than the time at which the power consumption of the electrical device has changed by a predetermined time (step S505: Yes), the associating unit 233 finally has the specific state. The corresponding person is associated with the tap 600 connected to the electric device whose power consumption has changed, and the correspondence relationship is stored as registration information in the storage unit 220 (step S506). On the other hand, if the time when the specific state was last reached is earlier than the time that is a predetermined time later than the time when the power consumption of the electrical device has changed (step S505: No), the person is associated with the tap 600. The process ends.

  As described above, in the fifth method, the time when the person who finally entered the specific state has entered the specific state is later than the time that is a predetermined time after the time when the power consumption of the electrical device has changed. Since the person who has finally entered the specific state is associated with the tap 600 to which the electric device whose power consumption has changed is connected, the accuracy of the association between the person and the tap 600 is improved as compared to the fourth method. be able to.

(Sixth method)
In the sixth method, when only one person is in a specific state after a time that is a predetermined time after the time when the power consumption of the electrical device changes, the power consumption of the person in the specific state changes. This is an example of associating with the tap 600 to which the electrical device is connected. That is, in the fifth method, an electric device whose power consumption has changed is connected to a person who has finally entered a specific state after a time that is a predetermined time after the time when the power consumption of the electric device has changed. Although it is associated with the tap 600, in the sixth method, when there are a plurality of persons who have entered a specific state after a time that is a predetermined time after the time when the power consumption of the electrical device has changed, the person and the tap 600 The correspondence with is put on hold.

  FIG. 26 is a diagram for explaining the association between the person and the tap 600 according to the sixth method. In the sixth method, as shown in FIG. 26 (a), the first determination unit 231 determines that the person has entered a specific state at each of time Tw1 and time Tw2, and then the second determination unit 232 at time Tq. When it is first determined that the power consumption of the electrical device has changed, time Tw2 is later than time Tq-S, which is a predetermined time S later than time Tq, and time Tw1 is later than time Tq-S. If it is before, the associating unit 233 associates the person who is in the specific state at the time Tw2 with the tap 600 to which the electric device whose power consumption has changed at the time Tq is connected.

  On the other hand, as shown in FIG. 26 (b), the first determination unit 231 determines that the person has entered a specific state at each of time Tw1 and time Tw2, and then the second determination unit 232 first performs electrical operation at time Tq. When it is determined that the power consumption of the device has changed, even if the time Tw2 is later than the time Tq-S that is a predetermined time S earlier than the time Tq, the time Tq that is the time Tw1 is a predetermined time S later than the time Tq If it is later than -S, the person who has entered the specific state at time Tw2 and the tap 600 to which the electric device whose power consumption has changed at time Tq is not associated, and the association is suspended. . The correspondence between the associated person and the tap 600 is stored in the storage unit 220 as registration information, and is excluded from processing by the subsequent association unit 233. On the other hand, the person who has been put on hold and the tap 600 are subjected to processing by the corresponding unit 233 thereafter.

  FIG. 27 is a flowchart illustrating a processing procedure according to the sixth method. First, the associating unit 233 monitors the notification from the first determination unit 231 and receives a notification from the first determination unit 231 as to whether or not the person has entered a specific state, that is, a notification that the person has entered the specific state. It is determined whether it has arrived (step S601). When the association unit 233 receives notification from the first determination unit 231 that the person has entered the specific state (step S601: Yes), the association unit 233 temporarily stores the time when the person has entered the specific state (step S601: Yes). Step S602). On the other hand, when the notification that the person has entered the specific state has not arrived (step S601: No), the process of step S602 is not performed.

  Next, the associating unit 233 monitors the notification from the second determining unit 232, and the second notification is whether or not the power consumption of the electrical device has changed, that is, the power consumption of the electrical device has changed. It is determined whether it has arrived from the determination unit 232 (step S603). Then, when the notification that the power consumption of the electrical device has changed has not arrived from the second determination unit 232 (step S603: No), the associating unit 233 returns to step S601 and repeats the subsequent processing. On the other hand, upon receiving a notification that the power consumption of the electrical device has changed (step S603: Yes), the associating unit 233 temporarily stores the time when the power consumption of the electrical device has changed (step S604). Then, the associating unit 233 refers to the time temporarily stored in step S602, identifies the person who has finally entered the specific state among the persons who have entered the specific state, and the person has entered the specific state. It is determined whether or not the current time is later than the time temporarily stored in step S604 and a predetermined time later than the time when the power consumption of the electrical device has changed (step S605).

  Then, if the time when the last state is the specific state is later than the time that is a predetermined time after the time when the power consumption of the electrical device changes (step S605: Yes), the associating unit 233 consumes the electrical device. It is determined whether or not another person other than the person who has finally entered the specific state is in the specific state after a time that is a predetermined time after the time when the power has changed (step S606). And associating part 233 will be in a specific state at the end, if there is no other person who is in a specific state after the time which went back for the predetermined time from the time when the power consumption of the electric equipment changed (Step S606: No). The corresponding person is associated with the tap 600 connected to the electric device whose power consumption has changed, and the correspondence is stored as registration information in the storage unit 220 (step S607). On the other hand, when the time when the power consumption of the electric device last changed is earlier than the time when the power consumption of the electric device has changed by a predetermined time (step S605: No), or when the power consumption of the electric device has changed. If a person other than the person who has finally entered the specific state is in the specific state after a time that is a predetermined time later than the predetermined time (step S606: Yes), the person is associated with the tap 600. The process ends.

  As described above, in the sixth method, when only one person is in a specific state after a time that is a predetermined time after the time when the power consumption of the electrical device changes, Since the electric device whose power consumption has changed is associated with the tap 600 to which the electric device is connected, the accuracy of the association between the person and the tap 600 can be improved as compared with the fifth method.
