  Hereinafter, embodiments of a power management apparatus, a power management system, a power management method, and a program will be described in detail with reference to the accompanying drawings. FIG. 1 is a diagram illustrating an overall configuration of a power management system 1 according to the embodiment. The power management system 1 manages the power consumption of a power device installed in a target area that is a target of power management. Specifically, the power management system 1 includes a power management device 100, a positioning server device 200, a plurality of smartphones 300, a plurality of monitoring cameras 400, and a plurality of PCs 500.

  The power management apparatus 100, the positioning server apparatus 200, the smartphone 300, and the PC 500 are connected to a network such as the Internet or a LAN (Local Area Network).

  The positioning server device 200 and the smartphone 300 and the positioning server 200 and the monitoring camera 400 are connected by a wireless communication network such as Wi-Fi (Wireless Fidelity), for example. Note that the wireless communication method is not limited to Wi-Fi. Further, the positioning server device 200 and the monitoring camera 400 may be connected by wire.

  The smartphone 300 is possessed by a user who uses the power device in the target area. Smartphone 300 communicates with power management apparatus 100 and positioning server apparatus 200 via a network. The smartphone 300 further functions as an information device that detects the operation of the user who owns the smartphone 300. The smartphone 300 is equipped with an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor, and transmits detection data of each sensor to the positioning server device 200 at regular intervals such as 1 second. Here, the detection data of the acceleration sensor is an acceleration vector. The detection data of the angular velocity sensor is an angular velocity vector. The detection data of the geomagnetic sensor is a magnetic orientation vector. The PC 500 is installed on each user's desk.

  The monitoring camera 400 images the target area. For example, the monitoring camera 400 is installed in the vicinity of the upper part of the room as the target area or in the vicinity of the door of the entrance / exit of the room. The monitoring camera 400 only needs to be able to image the target area, and the installation location is arbitrary.

  The positioning server device 200 receives detection data of each sensor included in the smartphone 300 and imaged image data obtained by the monitoring camera 400, and specifies the position of each user in the room based on these data. The positioning server device 200 generates user situation data in which the identified position is associated with the time when the position is detected. That is, the user status data in the present embodiment is information indicating the position of the user at each time. The positioning server device 200 transmits the generated user status data to the power management device 100.

  The power management apparatus 100 manages the power consumption of a power device installed in a target area to be managed by the power management system 1. In FIG. 1, a plurality of LED (Light Emitting Diode) lighting devices 600, a plurality of taps 700, and a plurality of air conditioners 800 are shown as power devices. In addition, the kind and number of electric power devices are not limited to the embodiments.

  Specifically, the power management apparatus 100 appropriately saves energy on the smartphone 300 possessed by each user or the PC 500 used by the user based on the power consumption of the device used by each user and the user's behavior. Send an energy saving message to encourage.

  The power management apparatus 100 and the power device are connected via a wireless communication network such as Wi-Fi, for example. Note that the communication method between the power management apparatus 100 and the power device is not limited to Wi-Fi, other wireless communication methods may be used, and an Ethernet (registered trademark) cable or PLC (Power Line Communications). ) Etc. can also be used.

  FIG. 2 is a block diagram illustrating a functional configuration of the power management apparatus 100. The power management apparatus 100 includes a communication unit 101, a power consumption management unit 102, an integrated data generation unit 103, a comparison unit 104, an action identification unit 105, a transmission condition determination unit 106, a transmission message determination unit 107, And a storage unit 110.

  The storage unit 110 stores various information. Specifically, the storage unit 110 stores a device management table 111, a transmission rule table 112, schedule data 113, and integrated data 114.

  The device management table 111, the transmission rule table 112, and the schedule data 113 are stored in the storage unit 110 in advance by a designer or the like. The integrated data 114 is generated by the integrated data generating unit 103 and written to the sequential storage unit 110.

  FIG. 3 is a diagram schematically illustrating the data configuration of the device management table 111. The crisis management table 111 is data that is referred to in order to specify a user who uses a power device installed in the target area. Specifically, the device management table 111 stores a power device ID that identifies a power device and a user ID that identifies a user who uses the power device in association with each other. Therefore, by referring to the device management table 111, the power device used by each user can be specified.

  The transmission rule table 112 will be described later. The schedule data 113 is data indicating a schedule for each user. The integrated data 114 is data generated by an integrated data generation unit 103 described later. The integrated data 114 will be described later.

  Returning to FIG. 2, the communication unit 101 transmits and receives information to and from other devices via the network. For example, the communication unit 101 receives user situation data from the positioning server device 200. The communication unit 101 also transmits an energy saving message to the smartphone 300 or the PC 500.

  The power consumption management unit 102 manages the power consumption amount of the power device to be managed for each user. Specifically, the power consumption management unit 102 refers to the device management table 111 of the storage unit 110 and identifies the power device used by each user. The power consumption management unit 102 further receives power consumption data indicating the amount of power consumption at each time from each power device to be managed. Based on the received power consumption data, the power consumption management unit 102 obtains total power consumption data indicating the total value of the power consumption amount at each time of the power equipment used by each user. That is, when there are a plurality of power devices used by the user, the total power consumption data indicates the total value of the power consumption amounts of the plurality of power devices, and there is only one power device used by the user. In this case, the total power consumption data indicates the power consumption amount of one power device.

  The integrated data generation unit 103 integrates the user status data received by the communication unit 101 and the total power consumption data generated by the power consumption management unit 102 to obtain integrated data for each user. That is, the integrated data is data indicating the total power consumption amount of the user and the position of the user at each time. The integrated data generation unit 103 accumulates the generated integrated data in the storage unit 110.

  The comparison unit 104 refers to the integrated data 114 generated by the integrated data generation unit 103 and accumulated in the storage unit 110, and periodically compares the total power consumption of each user with a preset threshold value. To do. In the present embodiment, the first threshold value and the second threshold value are set as threshold values to be compared with the total power consumption amount, and the comparison unit 104 determines the total consumption amount with each of the first threshold value and the second threshold value. Compare the amount of power.

  FIG. 4 is a diagram illustrating an example of the first threshold value and the second threshold value. Here, the first threshold is an upper limit value of the total power consumption allowed for the individual, and if the total power consumption exceeding the first threshold is continuously used, the power reduction target set in the target region is set. It is a value that cannot be achieved. The second threshold is a value that is smaller than the upper limit by a predetermined amount, and is a value that is used to determine the timing to notify the user before exceeding the first threshold so as not to exceed the first threshold. The first threshold value and the second threshold value are set in advance by a designer or the like.

  Returning to FIG. 2, based on the comparison result of the comparison unit 104, the behavior specifying unit 105, when the total power consumption of the predetermined target user is equal to or greater than the first threshold, With reference to the data 113, the action of the target user at the timing when the total power consumption equal to or greater than the first threshold is detected is specified.

  It should be noted that the action specifying unit 105 in the present embodiment refers to the schedule data 113 to be in the office without desk work or self-seat (experiment, internal meeting, etc.), or outside the office without self-seat (business trip, sales, vacation) Etc.). The action specifying unit 105 further specifies whether the user is seated or away from the desk at the time of desk work by referring to the integrated data 114.

  FIG. 5 is a diagram schematically illustrating the data configuration of the transmission rule table 112. The transmission rule table 112 stores a rule for transmitting an energy saving message. As shown in FIG. 5, the transmission rule table 112 includes a first table that is referred to when a total power consumption equal to or greater than a first threshold (hereinafter referred to as a first threshold value) is detected, and a second threshold. And a second table that is referred to when the total power consumption less than the first threshold value (hereinafter referred to as a second threshold value exceeding value) is detected. Since the data configuration of the first table and the second table is the same, the first table will be described below.

  The first table stores the user's behavior at the timing when the first threshold value is detected, the first notification related to the transmission of the energy saving message, and the second notification in association with each other. The first notification notifies the user as soon as possible that the first threshold value is detected. The second notification notifies the user proactively in order to prevent a similar situation from occurring in the future based on the detection of the first threshold value. The first notification and the second notification include information indicating the transmission timing and the transmission destination. The transmission destination is a user terminal used by the user, specifically, the smartphone 300 or the PC 500.

  In the first table shown in FIG. 5, for example, the user's action at the time of detection “desk work at his / her seat (sitting)” is associated with the transmission timing “immediately after detection” and the transmission destination “PC”. The transmission timing “immediately after detection” and the transmission destination “smartphone” are associated with the operation “desk work at own seat (away from desk)”.

  If the user's schedule at the timing at which the first threshold value is detected is deskwork and the user is seated at his / her seat, an energy saving message is transmitted to the smartphone at the timing immediately after detection. Is shown.

  Also, for example, the user's action “absence (in-house)” at the time of detection is associated with the transmission timing “immediately after detection” of the first notification and the transmission destination “smartphone” of the first notification. The transmission timing of “2 notification” “30 minutes before the event” and the transmission destination of the second notification are associated with “PC” when seated at the time of transmission, and “smartphone” when seated at the time of transmission. The “event” is a schedule related to the same action as the action of the corresponding user. For example, the “event” at the transmission timing associated with the user action “absent (in-house)” is a schedule of “absent (in-house)”.

  The second notification indicates that, for example, an energy saving message is sent 30 minutes before the start of an “absent (in-house)” schedule such as an experiment or an in-house meeting, and the user is seated at his / her seat at this timing. In some cases, the transmission destination is “PC”, and when the user is away from the seat, the transmission destination is “smart phone”.

  Thus, the first table not only notifies when the total power consumption exceeds the threshold, but also transmits the energy saving message at the timing before the start of the event that may exceed the threshold. A transmission rule related to the notification is stored.

  In the example shown in FIG. 5, the transmission timing in the second notification, which is associated with “absent (in-house)”, is different between the first table and the second table.

  As described above, in the present embodiment, since the first table and the second table are provided separately, the case where the first threshold value is detected and the case where the second value is detected. In, the rules for transmitting the energy saving message can be made different. That is, the energy saving message can be transmitted to different transmission destinations at different timings when the first threshold value is detected and when the second threshold value is detected.

  Returning to FIG. 2, the transmission condition determination unit 106 refers to the transmission rule table 112 based on the user behavior identified by the behavior identification unit 105 and the future user schedule identified from the schedule data 113. The transmission timing for transmitting the energy saving message and the transmission destination of the energy saving message are determined.

  For example, when the first threshold value is detected and the action of the user at the time of detection is desk work at his / her own seat, the transmission condition determination unit 106 refers to the first table shown in FIG. Determine as timing.

  For example, if the first threshold value is detected and the user's behavior at the time of detection is absent (in-house), the transmission condition determination unit 106 determines immediately after the detection as the transmission timing, and further schedule data 113 30 minutes before the user's future absence (in-house) schedule shown in FIG. That is, the transmission condition determining unit 106 according to the present embodiment functions as a transmission timing determining unit.

  The transmission message determination unit 107 determines the content of the energy saving message based on the comparison result between the total power consumption and the first threshold value and the second threshold value. The power management apparatus 100 according to the present embodiment transmits different energy saving messages when the first threshold value is detected and when the second threshold value is detected. When the first threshold value exceeding the first threshold value is detected, the transmission message determining unit 107 determines a caution message that alerts energy saving as the energy saving message to be transmitted to the user terminal, and the second threshold value is detected. In such a case, a warning message that can be recognized by the user as a more serious problem is determined as an energy saving message to be transmitted to the user terminal.

  The caution message is, for example, a message “Power consumption has exceeded peak I at X month X day X time. This may be because the power of the unused device A is not turned off.” The warning message is, for example, “When X month X day X, the power consumption has exceeded the peak 2. It may be because the power of the unused devices A and B is not turned off.” Message. In this way, the message may be a message that notifies the user of the time when the power consumption exceeds a predetermined threshold and the expected cause.

  As yet another example, the content of each message may be different between the first notification and the second notification.

  For example, as described above, the caution message in the first notification is as follows: “When X month X day X, the power consumption has exceeded the peak 1. The cause may be that the power of the unused device A is not turned off. "There is a message" and the caution message in the second notification is "The power consumption has exceeded peak 1 at X month X day X hour. The cause may be that the power of the unused device A is not turned off." The message may be “Please turn off the power of the device A before leaving for a long period of time.

  Similarly, as described above, the warning message in the first notification is as follows: “When X month X day X, the power consumption exceeded the peak 2. This is because the unused devices A and B are not turned off. The message “There is a possibility.” And the warning message in the second notification is “When X month X day X hour, power consumption exceeded peak 2. The power of unused devices A and B has not been turned off. Oita power is being used excessively when leaving for a long time, and it may adversely affect the achievement of the power reduction target. Please turn it off. "

  Note that the template of each message is stored in advance in the storage unit 110, and the transmission message determination unit 107 determines a transmission message to be actually transmitted based on the template stored in the storage unit 110.

  FIG. 6 is a block diagram showing a functional configuration of the positioning server device 200. The positioning server device 200 mainly includes a communication unit 201, a position specifying unit 202, a correction unit 203, and a storage unit 210.

  The storage unit 210 is a storage medium such as a hard disk drive (HDD) or a memory, and stores indoor map data in the control target area.

  The communication unit 201 receives detection data from each of an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor mounted on the smartphone 300 at regular time intervals. That is, the communication unit 201 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 201 receives a captured image from the monitoring camera 400. Further, the communication unit 201 transmits user status data to the power management apparatus 100.

  The position specifying unit 202 specifies the position of each user based on the received detection data. Specifically, the position specifying unit 202 uses the acceleration vector, the angular velocity vector, and the magnetic azimuth vector as the reference position, and the relative movement vector from the reference position to the position determined to be stationary. Ask for. 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 202 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 202 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. In addition, the position specifying unit 202 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 202 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 202 calculates 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 202 uses the relative movement vector from the door and the indoor map data that is the target area stored in the storage unit 210, after the user has moved. Specify the absolute position.

  As a result, the position specifying unit 202 can specify up to which desk the user is placed in the room. As a result, the shoulder width of a person, for example, approximately 60 cm or less (more specifically, approximately 40 cm). It becomes possible to specify the position of the user with an accuracy of less than about). As a result, it is possible to specify whether the user is sitting at his / her own seat or away from his / her seat.

  The correction unit 203 corrects the specified absolute position based on the captured image from the monitoring camera 400 and the map data stored in the storage unit 210. More specifically, the correction unit 203 determines whether 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, map data, or the like. And using the function of the map matching device disclosed in Japanese Patent Application Laid-Open No. 2009-14713, it is determined whether or not it is correct. If it is incorrect, the correction unit 203 corrects the correct absolute position, direction, and orientation obtained from the captured image and the map matching function.

  The correction unit 203 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.

  FIG. 7 is a diagram illustrating a wearing state of the smartphone 300. The smartphone 300 may be worn on the user's waist as shown in FIG. In the present embodiment, the smartphone 300 is used as an information device for detecting a human motion. However, if the information device includes an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor, the smartphone 300 can be used. It is not limited to portable terminals such as.

  In addition, the smartphone 300 includes information devices that detect human movements such as an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor, and the information devices that detect human movements may be mounted separately from the smartphone 300. Good.

  For example, FIG. 8 is a diagram illustrating an example in which an information device capable of detecting human movement is mounted separately from the smartphone 300. As shown in FIG. 8, separately from the smartphone 300, a small headset type sensor group 301 including an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor can be mounted on the head. In this case, the detection data detected by the sensor group 301 is transmitted directly to the positioning server device 200 by the sensor group 301. That is, the positioning server device 200 detects detection data from each of the acceleration sensor, angular velocity sensor, and geomagnetic sensor of the sensor group 301. As another example, each sensor of the sensor group 301 may transmit detection data to the positioning server device 200 via the smartphone 300. As described above, by attaching the sensor group 301 to the human head separately from each sensor of the smartphone 300, various posture detections can be performed.

  FIG. 9 is a flowchart showing power management processing by the power management apparatus 100. In the power management process, the communication unit 101 receives user status data from the positioning server 200 (step S100). Further, the power consumption management unit 102 receives power consumption data from the power device to be managed (step S101). Note that the communication unit 101 and the power consumption management unit 102 continuously receive user status data and power consumption data, respectively.

  Next, the integrated data generation unit 103 integrates the user status data received by the communication unit 101 and the power consumption data received by the power consumption management unit 102 to generate integrated data (step S102). The integrated data generation unit 103 further accumulates the generated integrated data in the storage unit 110 as appropriate.

  Next, the comparison unit 104 compares the total power consumption indicated in the integrated data of the target user with the first threshold value and the second threshold value (step S103). When the total power consumption is greater than or equal to the first threshold (step S104, Yes), the behavior specifying unit 105 determines the total power consumption greater than or equal to the first threshold based on the schedule data 113 and the integrated data 114 of the target user. The user's action is specified at the timing when the amount (first threshold value) is detected (step S105). In step S104, when the total power consumption is less than the first threshold (No in step S104), the process returns to step S103, and the comparison process between the total power consumption and the threshold is continued.

  Next, the transmission condition determination unit 106 refers to the transmission rule table 112 and determines a transmission condition including a transmission timing and a transmission destination based on the total power consumption of the target user and the behavior of the target user (step S106). ).

  At this time, based on the comparison result between the total power consumption of the target user and the first threshold value and the second threshold value, when the first threshold value is obtained and when the second threshold value is obtained. The transmission timing and the transmission destination are determined based on different transmission rules (first table and second table).

  Furthermore, the transmission message determination unit 107 determines an energy saving message based on the total power consumption of the target user and the behavior of the target user (step S107). The communication unit 101 transmits the energy saving message determined by the transmission message determination unit 107 to the transmission destination determined by the transmission condition determination unit 106 at the transmission timing determined by the transmission condition determination unit 106 (step S108). This completes the power management process.

  Thus, according to the power management system 1 according to the present embodiment, the total power consumption of the power devices used by each user is managed, and when the total power consumption exceeds the threshold, energy is saved in the user terminal. A message prompting the user can be transmitted, so that each person can refrain from using the power device according to the announcement. In other words, each person's awareness of energy saving can be improved and wasteful power consumption can be reduced.

  Further, according to the power management system 1, since a message for proactively saving energy can be transmitted to the user terminal at a timing when power consumption exceeding the threshold is predicted in the future, the energy saving awareness of each person is improved. , Wasteful power consumption can be prevented in advance.

  As described above, the present invention has been described using the embodiment, but various changes or improvements can be added to the above embodiment.

  As such a first modification example, other units included in the power management system 1 may include each unit other than the power consumption management unit 102 among the units included in the power management apparatus 100.

  As a second modification, the transmission rule table may store transmission conditions for each action in association with more detailed user actions.

  For example, the transmission rule table may store an experiment and an in-house meeting that are subdivided instead of absent (in-house) user behavior, and store different transmission conditions in association with these. Also, for example, the transmission rule table stores outings, domestic business trips, overseas business trips, and vacations that are subdivided into user actions that are absent (outside), and different transmission conditions are associated with these. You may remember.

  For example, the transmission timing of the second notification for a domestic business trip may be the sunrise company before the business trip, and as an exception, when the day before the business trip is a holiday, it may be the day before the holiday. In addition, for example, the transmission timing of the second notification for the vacation may be the sunrise company before the vacation, and as an exception, when the day before the vacation is an outside event such as a business trip, it may be the day before the outside event.

  As a third modification example, in the present embodiment, the user situation data is information indicating the position of the user, but the user situation data includes, in addition to this, stationary and walking, standing and sitting, Information indicating the operation state of the user, such as whether or not the user's line of sight faces the display device, may be included.

  In this case, the positioning server device 200 further includes an operation specifying unit that specifies these operation states. Furthermore, the action specifying unit 105 of the power management apparatus 100 specifies a more detailed user action based on the user operation situation included in the user situation data. And the memory | storage part 110 of the power management apparatus 100 memorize | stores the transmission rule table which matched different transmission conditions with each specified user's action. Thereby, the transmission process of the energy-saving message according to a user's action can be performed.

  In this case, the operation specifying unit of the positioning server device 200 determines the direction (orientation) of the human display device based on the direction of the magnetic orientation vector received from the geomagnetic sensor of the smartphone 300. In addition, when the person is stationary at the seat in front of the desk, the action identifying unit 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, the motion specifying unit obtains peaks of peaks and valleys of the acceleration component in the vertical direction, as in the dead reckoning device disclosed in Japanese Patent No. 4243684.

  FIG. 10 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. 10, in the case of the sitting 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 action specifying unit determines whether the person is in a sitting state or a standing state based on the peak interval. 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 specifying unit determines that the human motion state is the seated state. . In addition, when the interval from the peak of the trough of the vertical acceleration component to the peak of the peak is within a predetermined range from 0.5 seconds, the motion specifying unit determines that the human motion state is a standing state. .

  In this way, the motion specifying unit determines whether the human motion state is a standing state or a seated state, so that the position in the height direction of the human is approximately 50 cm or less (more specifically, approximately 40 cm or less). Means that it was detected in

  Further, as in the example shown in FIG. 8, 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 attached to the head, the action specifying unit can further detect the following human postures and actions.

  FIG. 11 is a diagram illustrating a waveform of the angular velocity data in the horizontal direction when the squatting operation and the standing operation are performed, respectively. From the acceleration data from the acceleration sensor, a waveform similar to the sitting motion and standing shown in FIG. 10 is detected, but it is difficult to discriminate between the squatting motion and the standing motion only by the acceleration data.

  For this reason, the motion specifying unit, together with the above-described method for discriminating between the sitting motion and the standing motion based on the waveform of FIG. By judging whether or not, a squatting action and a standing action are discriminated.

  Specifically, the motion identification unit first determines whether the 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 is within a predetermined range from 0.5 seconds. Determine whether.

  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 specifying unit determines the angular velocity vector in the horizontal direction of the angular velocity vector received from the angular velocity sensor. As shown in the waveform of FIG. 11, the component gradually increases from 0 and then reaches a peak of the mountain with a rapid increase. After suddenly decreasing from the peak of the mountain, the component gradually returns to 0. If it is 2 seconds, it is determined that the human action is a squatting action.

  Further, the action specifying unit 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. Then, when 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, the motion specifying unit determines the angular velocity in the horizontal direction of the angular velocity vector received from the angular velocity sensor. When the component reaches the peak of the valley stepwise from 0, gradually returns to 0 from the peak of the valley, and the time between them is about 1.5 seconds, as in the waveform shown in FIG. It is determined that the operation is a standing operation.

  As the angular velocity vector used in the determination of the squatting motion and the standing motion in the motion specifying unit, 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. 12 is a diagram illustrating a waveform of the 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 motion specifying unit gradually returns to 0 after the temporal change of the angular velocity component in the vertical direction of the angular velocity vector received from the angular velocity sensor gradually reaches the peak of the mountain from 0, as shown in the waveform of FIG. If the time between them is 3 seconds, it is determined that the direction changes to the right.

  In addition, the motion specifying unit gradually changes the angular velocity component in the vertical direction to 0 after gradually reaching the peak of the valley from 0 as shown in the waveform of FIG. When the time is 1.5 seconds, it is determined that the operation changes to the left.

  The motion specifying unit determines that 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 is similar to the waveform of FIG. If the change is indicated, it is determined that the direction of the whole body changes to the right or left.

  On the other hand, the motion specifying unit shows that the angular velocity component in the vertical direction 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 No. 1 shows a temporal change that is completely different from the waveform of FIG. 12, 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. 13 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 202 specifies the absolute position of a person in front of a desk and the action specifying unit detects that a person in front of the desk is seated. Then, in such a case, the motion identifying unit gradually increases the peak of the valley from 0 as the horizontal angular velocity component of the angular velocity vector received from the angular velocity sensor of the human head becomes like the waveform shown in FIG. Is reached 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 (an action to look up). Further, the motion specifying unit 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. 13, and then gradually returns to 0. When it 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. 14 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 seated state. Consider a case where the position specifying unit 202 specifies the absolute position of a person in front of a desk and the action specifying unit detects that a person in front of the desk is seated. Then, in such a case, the motion specifying unit determines that the angular velocity component in the horizontal direction of the angular velocity vector received from the angular velocity sensor of the human head suddenly peaks from 0 like the waveform shown in FIG. Is reached, then suddenly returns to 0, and the time between them is about 0.5 seconds, it is determined that the action is to remove the line of sight from the display in the seated state (looking down).

  Further, the action specifying unit reaches the valley peak while the angular velocity component in the horizontal direction rapidly decreases from 0 as shown in the waveform of FIG. 14, and then returns rapidly to 0. When it is about 1 second, it is determined that the operation is to return the line of sight to the display from a state where the line of sight is removed from the display in the sitting state.

  In this way, the action specifying unit is a posture and action that an office worker can take every day, that is, walking (standing state), standing (stationary state), sitting on a chair, squatting during work, sitting state or standing. It is possible to determine by the above-described method whether the direction (direction) is changed depending on the state, looking up at the sky in the seated state or standing state, or hitting in the seated state or standing state.

  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 motion specifying unit uses the function of the map matching device disclosed in Japanese Patent Laid-Open No. 2009-14713, and the vertical acceleration component is shown in FIG. When detected by the waveform, unlike the elevator lifting / lowering operation by the dead reckoning device of Japanese Patent No. 4243684, it can be determined with high accuracy whether the operation is a standing operation or a seating operation.
