When the electric lock 3 communicates with the key device 4, the state (locked state, unlocked state) of the electric lock 3 changes. Therefore, the resident of the customer facility 2 can change the state of the electric lock 3 using the key device 4. The electric lock 3 outputs information D1 regarding the change in the state of the electric lock 3. The key device 4 outputs information D2 for specifying the individual whose state of the electric lock 3 is changed. The electric lock 3 is connected to the gateway 7.

  The distribution board 8 has a main breaker and a plurality of branch breakers, and is configured to distribute the power supplied from the power supply 22 to the plurality of individual circuits 91, 92, 93. The plurality of individual circuits 91, 92, 93 are associated one-to-one with a plurality of people using the customer facility 2.

  Each of the plurality of individual circuits 91, 92, 93 here is a circuit having, for example, each of a plurality of branch circuits connected to the secondary terminal of the branch breaker as a unit. That is, each of the plurality of individual circuits 91, 92, 93 is composed of one or more branch circuits. Each of the branch circuits includes a wiring path connected to the secondary terminal of the branch breaker, a wiring device (outlet, wall switch, etc.), and various electrical loads (lighting device, air conditioner, etc.). ing. For example, when the person (resident) who uses the customer facility 2 is a family of three persons including a father, a mother, and a child, the plurality of individual circuits 91, 92, and 93 are associated with the father, the mother, and the child, respectively. In this case, the individual circuit including the lighting equipment and the air conditioner in the child room is associated with the child.

  The measuring device 5 is attached to the distribution board 8 and measures power consumption for each of the plurality of individual circuits 91, 92, 93. The measuring device 5 outputs the measurement result (measurement value) of the power consumption as information D3 regarding the power consumption in the customer facility 2.

  Hereinafter, the information D1 output from the electric lock 3 is referred to as “locking / unlocking information”, the information D2 output from the key device 4 is referred to as “specific information”, and the information D3 output from the measuring device 5 is referred to as “power”. It is called “information”. FIG. 1 schematically shows how the first acquisition unit 11, the second acquisition unit 12, and the third acquisition unit 13 acquire the locking / unlocking information D1, the specific information D2, and the power information D3, respectively.

  The first acquisition unit 11 acquires the lock / unlock information D <b> 1 output from the electric lock 3. A communication path including the network 21 and the gateway 7 is formed between the server 101 and the electric lock 3. Therefore, the first acquisition unit 11 acquires the locking / unlocking information D1 from the electric lock 3 via the network 21 and the gateway 7. The first acquisition unit 11 is configured to acquire the locking / unlocking information D1 from the electric lock 3 each time the locking state and the unlocking state of the electric lock 3 are switched. The first acquisition unit 11 is electrically connected to the estimation unit 14. The first acquisition unit 11 outputs the acquired locking / unlocking information D1 to the estimation unit 14.

  The locking / unlocking information D1 acquired by the first acquisition unit 11 is information indicating which of a plurality of change patterns including a first pattern and a second pattern is a change in the state of the electric lock 3. The first pattern is a pattern representing a change of the electric lock 3 from the locked state to the unlocked state. The second pattern is a pattern representing the change of the electric lock 3 from the unlocked state to the locked state.

  The second acquisition unit 12 acquires the specific information D2 output from the key device 4. A communication path including the network 21, the gateway 7, and the electric lock 3 is formed between the server 101 and the key device 4. Therefore, the second acquisition unit 12 acquires the specific information D2 from the key device 4 via the network 21, the gateway 7, and the electric lock 3. The second acquisition unit 12 specifies the specific information from the key device 4 every time the locked state and the unlocked state of the electric lock 3 are switched, that is, every time the first acquisition unit 11 acquires the unlocking information D1 from the electric lock 3. It is configured to obtain D2. The second acquisition unit 12 is electrically connected to the estimation unit 14. The second acquisition unit 12 outputs the acquired specific information D2 to the estimation unit 14.

  The third acquisition unit 13 acquires the power information D3 output from the measurement device 5. A communication path including the network 21 and the gateway 7 is formed between the server 101 and the measuring device 5. Therefore, the third acquisition unit 13 acquires power information D3 from the measurement device 5 via the network 21 and the gateway 7. The third acquisition unit 13 is configured to acquire power information D3 from the measurement device 5 periodically. The third acquisition unit 13 is electrically connected to the estimation unit 14. The third acquisition unit 13 outputs the acquired power information D3 to the estimation unit 14.

  Based on the information acquired by the first acquisition unit 11, the second acquisition unit 12, and the third acquisition unit 13 (locking / unlocking information D1, specific information D2, and power information D3), the estimation unit 14 performs the behavior of the estimation target person. Is estimated. At this time, the estimation unit 14 estimates the behavior of the estimation target person using the individual specified from the specific information D2 as the estimation target person. The estimation part 14 estimates a presumed person's action based on the locking / unlocking information D1, the specific information D2, and the electric power information D3 by using a predetermined estimation condition. Examples of the behavior of the estimation target person that can be estimated by the estimation unit 14 include return of the estimation target person, going out, and going to bed.

  As a basic process, the estimation unit 14 uses the first determination process for determining whether or not a person exists in the customer facility 2 and the determination result of the first determination process to determine the behavior of the estimation target person. A second determination process for determining is performed. The first determination process is a process in which the estimation unit 14 determines whether there is a person in the customer facility 2 based on the power information D3 acquired by the third acquisition unit 13. For example, if the power consumption of the customer facility 2 exceeds a predetermined threshold, the estimation unit 14 determines that there is a person in the customer facility 2, and if the power consumption of the customer facility 2 is equal to or less than the threshold, It is determined that there is no person in the customer facility 2. The second determination process is performed by the estimation unit 14 based on the determination result of the first determination process and the locking / unlocking information D1 acquired by the first acquisition unit 11 and the specific information D2 acquired by the second acquisition unit 12. This is processing for specifying the target person and the action. Specific processing for estimating the behavior of the estimation target person in the estimation unit 14 will be described in the section “(2.2) Operation”. The estimation unit 14 outputs the estimation result (the behavior of the estimation target person) to the output unit 15.

  The output unit 15 is configured to present (notify) the estimation result of the estimation unit 14 to the resident of the customer facility 2. Here, the output unit 15 outputs the estimation result of the estimation unit 14 to the information terminal 6 possessed by the resident of the customer facility 2. That is, since the server 101 is connected to the network 21, the output unit 15 can output the estimation result of the estimation unit 14 to the information terminal 6 connected to the network 21.

  Here, the information terminal 6 that is the output destination of the estimation result of the estimation unit 14 by the output unit 15 can be registered in advance. Specifically, in the storage unit 16, identification information (address or the like) unique to the information terminal 6 is stored as output destination information, and the output unit 15 is an information terminal in which the identification information is stored in the storage unit 16. 6, the estimation result of the estimation unit 14 is output. Furthermore, a plurality of information terminals 6 can be registered as output destinations of the estimation results of the estimation unit 14. Therefore, if there are a plurality of information terminals 6 associated one-to-one with a plurality of residents of the customer facility 2, the estimation result of the estimation unit 14 can be output to the plurality of information terminals 6. .

  In the present embodiment, the output unit 15 sends the estimation unit to at least one information terminal 6 corresponding to an individual other than the person to be estimated among a plurality of information terminals 6 to which the estimation result of the estimation unit 14 is output. It is configured to output 14 estimation results. For example, when the resident of the customer facility 2 is a family of three of a father, a mother and a child, and the estimation target person is a child, the output unit 15 sends an estimation unit to at least one information terminal 6 of the father and the mother. 14 estimation results are output.

  The information terminal 6 includes, for example, a smartphone, a tablet terminal, or a personal computer, and is configured to be able to communicate with the server 101 via the network 21. That is, the information terminal 6 is mainly configured by a computer having a processor and a memory. The information terminal 6 acquires (receives) the estimation result of the estimation unit 14 from the server 101, and presents the estimation result of the estimation unit 14 to the resident who owns the information terminal 6 by displaying the estimation result. The information terminal 6 receives the push notification from the server 101 and acquires the estimation result of the estimation unit 14. The resident who has the information terminal 6 can check the estimation result of the estimation unit 14 not only when in the customer facility 2 but also when he is out.

  Here, the information terminal 6 has a display unit 61. The information terminal 6 receives the estimation result of the estimation unit 14 and creates a screen to be displayed on the display unit 61. The information terminal 6 presents the estimation result of the estimation unit 14 to the resident who holds the information terminal 6 by displaying the created screen on the display unit 61.

  The storage unit 16 stores an estimation condition used when the estimation unit 14 estimates the behavior of the estimation target person. Furthermore, the storage unit 16 stores the locking / unlocking information D1 acquired from the electric lock 3 by the first acquisition unit 11 in time series. Here, the storage unit 16 stores the specific information D2 acquired by the second acquisition unit 12 from the key device 4 in association with the locking / unlocking information D1. In addition, the power information D3 acquired by the third acquisition unit 13 from the measurement device 5 is stored in the storage unit 16 according to a time series.

  In the present embodiment, as an example, the network 21 is the Internet. A communication method between the electric lock 3 and the key device 4 is wireless communication using radio waves as a medium, such as Bluetooth (registered trademark). On the other hand, the communication method between the electric lock 3 and the gateway 7 and the communication method between the measuring device 5 and the gateway 7 are wired communication. However, the communication method between the electric lock 3 and the key device 4, the communication method between the electric lock 3 and the gateway 7, and the communication method between the measuring device 5 and the gateway 7 are wireless communication and wired communication. Any communication method may be used.

  Furthermore, the gateway 7 is a HEMS (Home Energy Management System) controller, and displays the power information D3 on a monitor, or controls a device (compatible with HEMS) based on the power information D3. The gateway 7 is mainly composed of a computer having a processor and a memory. The gateway 7 may be connected to the network 21 via a network device such as a router.

  Hereinafter, the configuration of each of the electric lock 3, the key device 4, and the measuring device 5 will be described in more detail with reference to FIG. FIG. 2 schematically illustrates how the first acquisition unit 11, the second acquisition unit 12, and the third acquisition unit 13 acquire the locking / unlocking information D1, the specific information D2, and the power information D3, respectively. 2, illustrations other than the first acquisition unit 11, the second acquisition unit 12, the third acquisition unit 13, the electric lock 3, the key device 4, and the measurement device 5 are omitted.

  The electric lock 3 includes a detection unit 31, a (first) control unit 32, a drive unit 33, a (first) communication interface (hereinafter referred to as “I / F”) 34, ( 1st) wireless I / F35.

  The detection unit 31 is a sensor whose electrical state (for example, contact ON / OFF) changes between when the electric lock 3 is in the locked state and when it is in the unlocked state. The control unit 32 generates locking / unlocking information D <b> 1 based on a change in the electrical state of the detection unit 31. For example, the control unit 32 determines that the electric lock 3 has changed from the locked state to the unlocked state by changing the output voltage of the detection unit 31 from less than a predetermined determination threshold value to greater than or equal to the determination threshold value. D1 is generated. When the electric lock 3 changes from the locked state to the unlocked state, the control unit 32 generates locking / unlocking information D1 indicating that the change in the state of the electric lock 3 is the first pattern. When the electric lock 3 changes from the unlocked state to the locked state, the control unit 32 generates the unlocking information D1 indicating that the change in the state of the electric lock 3 is the second pattern.

  However, only information obtained together with the specific information D2 in the locking / unlocking information D1 is used for the estimation of the action in the estimation unit 14. Here, the specific information D2 is information output from the key device 4. Therefore, only when the resident of the customer facility 2 changes the state of the electric lock 3 using the key device 4, the locking / unlocking information D1 necessary for estimating the behavior in the estimation unit 14 is generated. . Therefore, in the present embodiment, only when the state of the electric lock 3 is changed by the key device 4, the control unit 32 generates the locking / unlocking information D1.

  For example, depending on the specification of the electric lock 3, the electric lock 3 may be automatically locked within a certain time after the electric lock 3 changes from the locked state to the unlocked state. Further, depending on the residents of the customer facility 2, the electric lock 3 may be always locked while at home. In these cases, for example, when the resident of the customer facility 2 returns home, the electric lock 3 is locked immediately after the electric lock 3 changes from the locked state to the unlocked state. The key device 4 is not used for locking. Therefore, the control unit 32 does not generate the locking / unlocking information D1. Thereby, even if the electric lock 3 is locked without using the key device 4 after the electric lock 3 is changed from the locked state to the unlocked state, the state of the electric lock 3 in the unlocking information D1 remains in the unlocked state. It becomes.

  Further, the control unit 32 controls the drive unit 33 to drive the electric lock 3 so as to switch between the locked state and the unlocked state. The communication I / F 34 has a communication function with the gateway 7. The wireless I / F 35 has a wireless communication function with the key device 4.

  Therefore, the locking / unlocking information D1 related to the change in the state of the electric lock 3 is generated by the control unit 32 and transmitted from the communication I / F 34 to the server 101 via the gateway 7. Thereby, in the 1st acquisition part 11, it becomes possible to acquire locking / unlocking information D1.

  The key device 4 includes a memory 41, a (second) control unit 42, and a (second) wireless I / F 43. The key device 4 is composed of, for example, a smartphone or an IC card, and is carried by a resident of the customer facility 2. If there are a plurality of residents of the customer facility 2, each of the plurality of residents possesses the key device 4.

  The memory 41 stores identification information (ID) unique to the key device 4. The control unit 42 reads identification information from the memory 41, and generates specific information D2 based on the identification information. The wireless I / F 43 has a wireless communication function with the wireless I / F 35 of the electric lock 3. When the resident of the customer facility 2 operates the key device 4, wireless communication is performed between the key device 4 and the electric lock 3, and an operation signal including specific information D <b> 2 is transmitted from the key device 4 to the electric lock 3. Is done. When the authentication of the specific information D2 is successful with the electric lock 3, the state of the electric lock 3 changes.

  Therefore, the specific information D2 for specifying the individual who has changed the state of the electric lock 3 is generated by the control unit 42, transmitted from the wireless I / F 43 to the electric lock 3, and further from the electric lock 3 to the gateway 7 Via the server 101. As a result, the second acquisition unit 12 can acquire the specific information D2.

  The measurement device 5 includes a measurement unit 51, a (third) control unit 52, and a (second) communication I / F 53. The measuring device 5 is housed in a cabinet of the distribution board 8.

  The measuring unit 51 measures the power consumption for each of the plurality of branch circuits using the output of the current sensor that measures the current flowing through each of the plurality of branch breakers. As the current sensor, a Rogowski coil is used that is composed of an air-core coil that does not use a core (coreless) and generates an output corresponding to the current passing through the through hole. The current sensor may be, for example, a CT (Current Transformer) sensor, a Hall element, a magnetoresistive element such as a GMR (Giant Magnetic Resistances) element, or a shunt resistance.

  The control unit 52 obtains the power consumption for each of the plurality of individual circuits 91, 92, 93 using the measurement value (power consumption) by the measurement unit 51. The control unit 52 generates power information D3 based on the power consumption for each of the plurality of individual circuits 91, 92, 93. The communication I / F 53 has a communication function with the gateway 7.

  Therefore, the power information D3 related to the power consumption in the customer facility 2 is generated by the control unit 52 and transmitted from the communication I / F 53 to the server 101 via the gateway 7. As a result, the third acquisition unit 13 can acquire the power information D3.

(2.2) Operation Next, the operation of the behavior estimation system 1 will be described with reference to FIGS. 3 to 6 show the action estimation results in the locking / unlocking information D1, the power information D3, and the estimation unit 14 in order from the top, with the horizontal axis as the time axis. Here, whether the electric lock 3 is in the locked state or the unlocked state is shown as the unlocking information D1, and the power consumption is shown in a graph format as the power information D3. The behavior estimation result in the estimation unit 14 shows a signal that changes from the L (Low) level to the H (High) level when the estimation target person takes the behavior to be detected. In the following, when the person (resident) who uses the customer facility 2 is a family of three persons, a father, a mother and a child, and the child operates the electric lock 3 with the key device 4, that is, the estimation target person The case where is a child is illustrated.

(2.2.1) Estimation of return home First, when the estimation target person returns, that is, the estimation target person has moved from outside the customer facility 2 into the customer facility 2 as the behavior of the estimation target person. The operation of the behavior estimation system 1 will be described with reference to FIG. FIG. 3 illustrates a case where the child (estimation target person) returns home at time t1.

  In the estimation unit 14, the first acquisition unit 11 acquires the locking / unlocking information D1 representing the first pattern, and the power consumption of the customer facility 2 exceeds a predetermined threshold (first threshold) P1 in the first monitoring period T1. Then, it is estimated that the estimation target person has moved from outside the customer facility 2 into the customer facility 2. The 1st monitoring period T1 here is a period from the time t1 when the 1st acquisition part 11 acquired the locking / unlocking information D1 showing a 1st pattern to the time t3 when predetermined time (for example, 10 minutes) passed.

  That is, when the child returns at time t1, the electric lock 3 is operated by the key device 4 possessed by the child, so that the state of the electric lock 3 changes from the locked state to the unlocked state at time t1. At this time, the 1st acquisition part 11 acquires locking / unlocking information D1 showing that the change of the state of electric lock 3 is the 1st pattern. Furthermore, the 2nd acquisition part 12 acquires specific information D2 showing that the individual who changed the state of the electric lock 3 is a child.

  Thereafter, since the child moves into the customer facility 2 and uses the electric equipment in the customer facility 2, the power consumption of the customer facility 2 increases after time t1. In the example of FIG. 3, since the power consumption of the customer facility 2 exceeds the first threshold value P1 at time t2 within the first monitoring period T1, the estimation unit 14 performs the behavior of the child (estimation target person) at time t2. Detecting the action of returning home. That is, the estimation unit 14 estimates that the child has returned home.

  The output unit 15 outputs (transmits) the estimation result of the estimation unit 14 that the child has returned to the information terminal 6 possessed by at least one of the father and the mother. Thereby, at least one of the father and mother holding the information terminal 6 can know that the child has come home.

  The first monitoring period T1 may end when the estimation unit 14 estimates that the child has returned home (time t2). In this case, the length of the first monitoring period T1 is variable.

  The estimation part 14 is not restricted to the structure which judges whether the power consumption of the consumer facility 2 exceeds 1st threshold value P1 continuously from the start time of 1st monitoring period T1. For example, the estimation unit 14 may determine whether the power consumption of the customer facility 2 exceeds the first threshold P1 at the end of the first monitoring period T1. In this case, even if the power consumption of the customer facility 2 exceeds the first threshold value P1 during the first monitoring period T1, the estimation unit 14 estimates the behavior of returning home at the end of the first monitoring period T1. Alternatively, the estimation unit 14 first monitors whether or not the representative value (average value, median value, mode value, minimum value, or maximum value) of power consumption in the first monitoring period T1 exceeds the first threshold value P1. The determination may be made at the end of the period T1.

(2.2.2) Bedtime Estimation Next, the operation of the behavior estimation system 1 in the case where the bedtime of the estimation target person is estimated as the behavior of the estimation target person will be described with reference to FIG. FIG. 4 illustrates a case where the child (estimation target person) who came home at time t1 goes to bed at time t4.

  The estimation unit 14 determines that the power consumption of the customer facility 2 is a predetermined threshold (second threshold) during the second monitoring period T2 after the estimation that the estimation target person has moved from outside the customer facility 2 into the customer facility 2. When P2 or less, the estimation target person is estimated to have gone to bed. The second monitoring period T2 here is, for example, a period from the time t3 when the first monitoring period T1 ends until a predetermined time (for example, 6 hours) elapses.

  That is, since it is estimated that the child has returned home as described in the section “(2.2.1) Estimation of return home”, since the child is active in the customer facility 2, the consumer is active after time t 1. The power consumption of the facility 2 increases. Thereafter, when the child goes to bed, the power of various electric loads is turned off, so that the power consumption of the customer facility 2 is reduced. In the example of FIG. 4, since the power consumption of the customer facility 2 becomes equal to or less than the second threshold value P2 (= first threshold value P1) at time t4 within the second monitoring period T2, the estimation unit 14 at time t4 The behavior of going to bed is detected as the behavior of the child (estimated person). That is, the estimation unit 14 estimates that the child has gone to bed.

  The output unit 15 outputs (transmits) the estimation result of the estimation unit 14 that the child has gone to bed to the information terminal 6 possessed by at least one of the father and the mother. Thereby, at least one of the father and mother holding the information terminal 6 can know that the child has gone to bed.

  Note that the second monitoring period T2 may be a period after the end of the first monitoring period T1, for example, a period after the end of the first monitoring period T1 and from 20:00 to 23:00. It may be limited by the belt.

  When the first monitoring period T1 ends at time t2 when the estimation unit 14 estimates that the child has returned home, the second monitoring period T2 may start from time t2. In addition, the second monitoring period T2 may end when the estimation unit 14 estimates that the child has gone to bed (time t4). In this case, the length of the second monitoring period T2 is variable.

  The estimation part 14 is not restricted to the structure which judges whether the power consumption of the consumer facility 2 is below 2nd threshold value P2 continuously from the start time of 2nd monitoring period T2. For example, the estimation unit 14 may determine whether the power consumption of the customer facility 2 is equal to or less than the second threshold P2 at the end of the second monitoring period T2. In this case, even if the power consumption of the customer facility 2 becomes equal to or less than the second threshold value P2 during the second monitoring period T2, the estimation unit 14 estimates the action of going to bed at the end of the second monitoring period T2. Alternatively, the estimation unit 14 determines whether the representative value (average value, median value, mode value, minimum value, or maximum value) of power consumption in the second monitoring period T2 is equal to or less than the second threshold value P2. The determination may be made at the end of the monitoring period T2.

(2.2.3) Estimation of going out Next, when the estimation target person's outing, that is, the estimation target person's movement from the customer facility 2 to the outside of the customer facility 2 is estimated as the behavior of the estimation target person The operation of the behavior estimation system 1 will be described with reference to FIG. FIG. 5 illustrates a case where the child (estimation target person) goes out at time t12.

  In the estimation unit 14, the first acquisition unit 11 acquires the locking / unlocking information D1 representing the second pattern, and the power consumption of the customer facility 2 falls below a predetermined threshold (third threshold) P3 in the third monitoring period T3. Then, it is estimated that the estimation target person has moved from the customer facility 2 to the outside of the customer facility 2. The third monitoring period T3 here is a period from time t12 when the first acquisition unit 11 acquires the locking / unlocking information D1 representing the second pattern to time t13 when a predetermined time (for example, 10 minutes) has elapsed.

  That is, when the child goes out at time t12, since the electric lock 3 is operated by the key device 4 possessed by the child, the state of the electric lock 3 changes from the unlocked state to the locked state at time t12. At this time, the 1st acquisition part 11 acquires locking / unlocking information D1 showing that the change of the state of electric lock 3 is the 2nd pattern. Furthermore, the 2nd acquisition part 12 acquires specific information D2 showing that the individual who changed the state of the electric lock 3 is a child.

  Further, in this case, since the power of the electric load in the customer facility 2 is turned off before the child moves out of the customer facility 2, the power consumption of the customer facility 2 is reduced. In the example of FIG. 5, since the power consumption of the customer facility 2 becomes equal to or less than the third threshold value P3 at time t11 immediately before time t12, the power consumption of the customer facility 2 is continuously continued in the third monitoring period T3. Is less than or equal to the third threshold value P3. Therefore, at time t13, which is the end point of the third monitoring period T3, the estimation unit 14 detects the behavior of going out as the behavior of the child (estimation target person). That is, the estimation unit 14 estimates that the child has gone out.

  The output unit 15 outputs (transmits) the estimation result of the estimation unit 14 that the child has gone out to the information terminal 6 possessed by at least one of the father and the mother. Thereby, at least one of the father and mother holding the information terminal 6 can know that the child has gone out.

  The timing at which the estimation unit 14 determines whether the power consumption of the customer facility 2 is equal to or less than the third threshold value P3 is not limited to the end point of the third monitoring period T3. For example, the estimation unit 14 may continuously determine whether or not the power consumption of the customer facility 2 is equal to or less than the third threshold P3 from the start of the third monitoring period T3. In this case, even in the middle of the third monitoring period T3, when the power consumption of the customer facility 2 becomes equal to or less than the third threshold value P3, the estimation unit 14 estimates an action of going out. In this case, the third monitoring period T3 may end when the estimation unit 14 estimates the action of going out. Alternatively, the estimation unit 14 determines whether the representative value (average value, median value, mode value, minimum value, or maximum value) of power consumption in the third monitoring period T3 is equal to or less than the third threshold value P3. The determination may be made at the end of the monitoring period T3.

(2.2.4) Estimation of Temporary Return Next, the operation of the behavior estimation system 1 in the case of estimating the temporary return of the estimation target person as the behavior of the estimation target person will be described with reference to FIG. The temporary return here means an action in which the estimation target person who has gone out leaves the house once (for example, within 3 minutes), for example, in order to take forgotten things. FIG. 6 illustrates a case where the child (estimation target person) returns home temporarily at time t21.

  When the first acquisition unit 11 acquires the information representing the first pattern and the information representing the second pattern within a certain time, the estimation unit 14 is information D3 regarding the power consumption of the customer facility 2 in the fourth monitoring period T4. Based on the above, it is estimated whether or not the estimation target person exists in the customer facility 2. The fourth monitoring period T4 here is a time at which a predetermined time (for example, 10 minutes) has elapsed from the time t22 when the first acquisition unit 11 finishes acquiring both information representing the first pattern and information representing the second pattern. This is the period up to t23.

  That is, when the child comes home temporarily at time t21, the electric lock 3 is operated by the key device 4 possessed by the child, so that the state of the electric lock 3 changes from the locked state to the unlocked state at time t21. . At this time, the 1st acquisition part 11 acquires locking / unlocking information D1 showing that the change of the state of electric lock 3 is the 1st pattern. Furthermore, the 2nd acquisition part 12 acquires specific information D2 showing that the individual who changed the state of the electric lock 3 is a child.

  Thereafter, when the child goes out at time t22, since the electric lock 3 is operated by the key device 4 possessed by the child, the state of the electric lock 3 changes from the unlocked state to the locked state at time t22. At this time, the 1st acquisition part 11 acquires locking / unlocking information D1 showing that the change of the state of electric lock 3 is the 2nd pattern. Furthermore, the 2nd acquisition part 12 acquires specific information D2 showing that the individual who changed the state of the electric lock 3 is a child.

  Here, if the time from when the child returns home to when he / she goes out (from time t21 to time t22) is within a certain time (for example, 3 minutes), the first acquisition unit 11 displays the unlocking information representing the first pattern. D1 and the locking / unlocking information D1 representing the second pattern are acquired within a certain time. And in the example of FIG. 6, after the time t22 when the 1st acquisition part 11 acquired the locking / unlocking information D1 (locking / unlocking information D1 showing a 2nd pattern) at the end, the big raise of the power consumption of the consumer facility 2 is Absent. Therefore, in the fourth monitoring period T4, the power consumption of the customer facility 2 does not exceed the predetermined threshold (fourth threshold) P4. Therefore, the estimation unit 14 estimates that the estimation target person does not exist in the customer facility 2 based on the information related to the power consumption of the customer facility 2 in the fourth monitoring period T4.

  As a result, at time t23 which is the end point of the fourth monitoring period T4, the estimation unit 14 detects the behavior of returning home temporarily as the behavior of the child (estimation target person). That is, the estimating unit 14 estimates that the child has returned home temporarily (going out of the house immediately after returning home).

  The output unit 15 outputs (transmits) the estimation result of the estimation unit 14 that the child has returned home to the information terminal 6 possessed by at least one of the father and the mother. Thereby, at least one of the father and mother holding the information terminal 6 can know that the child has returned home temporarily.

  Here, when the estimation unit 14 also performs the home return described in the section “(2.2.1) Home return estimation”, the output unit 15 may notify the temporary home after the home return notification. Alternatively, the return home and the temporary return home may be alternatively selected and notified. In the former case, the output unit 15 outputs an estimation result that the estimation target person has returned when the estimation unit 14 estimates that he / she is going home, and then, when the estimation unit 14 estimates that he / she is going home temporarily, The estimated result that the person has returned home is output. Accordingly, it is possible to shorten the time until the information terminal 6 is notified of the estimation target person returning home after the estimation target person returns home. On the other hand, in the latter case, the output unit 15 does not output the estimation result when the estimation unit 14 estimates that the user is going home, and the estimation is performed when the fourth monitoring period T4 has elapsed and it is determined whether the home is temporarily returned. An estimation result that the subject has returned home or has returned home is output.

  The timing at which the estimation unit 14 determines whether the power consumption of the customer facility 2 is equal to or less than the fourth threshold value P4 is not limited to the end point of the fourth monitoring period T4. For example, the estimation unit 14 may continuously determine whether or not the power consumption of the customer facility 2 is equal to or less than the fourth threshold value P4 from the start point of the fourth monitoring period T4. In this case, even in the middle of the fourth monitoring period T4, when the power consumption of the customer facility 2 becomes equal to or lower than the fourth threshold value P4, the estimation unit 14 estimates the behavior of returning home temporarily. In this case, the fourth monitoring period T4 may end when the estimation unit 14 estimates that the estimation target person has temporarily returned home. Alternatively, the estimation unit 14 determines whether the representative value (average value, median value, mode value, minimum value, or maximum value) of power consumption in the fourth monitoring period T4 is equal to or less than the fourth threshold value P4. The determination may be made at the end of the monitoring period T4.

  In addition, the behavior estimation system 1 can detect (estimate) the estimation target person's temporary outing in the same procedure as the temporary return home. The temporary going out here means an action in which the estimation target person goes home immediately after going out (for example, within 3 minutes), for example, for taking out garbage. In this case, the 1st acquisition part 11 will acquire the locking / unlocking information D1 showing a 2nd pattern, and the locking / unlocking information D1 showing a 1st pattern within a fixed time. And after the time when the 1st acquisition part 11 acquired locking / unlocking information D1 (locking / unlocking information D1 showing the 1st pattern) at the end, the power consumption of consumer facility 2 becomes large. Therefore, the estimation unit 14 estimates that the estimation target person exists in the customer facility 2 based on the information regarding the power consumption of the customer facility 2 in the fourth monitoring period T4. As a result, at the end point of the fourth monitoring period T4, the estimation unit 14 detects the behavior of going out temporarily as the behavior of the estimation target person. That is, the estimation unit 14 estimates that the estimation target person has temporarily left the house (goes out and returns home immediately).

  Here, when the estimation unit 14 also performs the outing estimation described in the section “(2.2.3) Outgoing estimation”, the output unit 15 may notify the temporary outing after the outing notification. Alternatively, the user may alternatively select to go out and temporarily go out. This is the same as in the case of temporary return home.

(2.2.5) Estimation of Home or Absence The estimation unit 14 determines whether the estimation target person exists in the customer facility 2 and the absence state in which the estimation target person does not exist in the customer facility 2. It may be estimated as an action of the estimation target person. That is, the estimation unit 14 estimates that the estimation target person is at home after estimating that the estimation target person has returned home. After estimating that the estimation target person has gone out, the estimation unit 14 estimates that the estimation target person is in an absent state. Moreover, the estimation part 14 estimates that an estimation object person exists in an absence state after estimating that the estimation object person came home temporarily. The estimation unit 14 estimates that the estimation target person is at home after estimating that the estimation target person has temporarily left.

  Here, when it is estimated that the estimation target person has temporarily returned home, the estimation unit 14 may continue the estimation result (that is, the absence state) before the estimation target person has temporarily returned home. In short, when the estimation target person temporarily returns home, the estimation unit 14 continuously estimates that the estimation target person is absent from before the estimation target person returns home. Similarly, even when it is estimated that the estimation target person has temporarily left, the estimation unit 14 may continue the estimation result (that is, the home state) before the estimation target person has temporarily left. In short, when the estimation target person goes out temporarily, the estimation unit 14 continuously estimates the home state from before the estimation target person goes out to after returning home.

(2.2.6) Others The third acquisition unit 13 may acquire information (power information D3) regarding power consumption for each of the plurality of individual circuits 91, 92, and 93. In this case, the estimation unit 14 estimates the behavior of the estimation target person based on the information on the power consumption of the individual circuit corresponding to the estimation target person among the power information D3 acquired by the third acquisition unit 13. Composed. Thereby, for example, when the resident of the customer facility 2 is a family of three of a father, a mother, and a child, and the estimation target person is a child, the estimation unit 14 selects an individual corresponding to the child in the power information D3. The child's behavior is estimated based on the information about the power consumption of the circuit.

  The first threshold value P1, the second threshold value P2, the third threshold value P3, and the fourth threshold value P4 may be the same value or different values. The first monitoring period T1, the third monitoring period T3, and the fourth monitoring period T4 may have the same or different length of time.

(2.3) Method and Program By adopting the following behavior estimation method, functions equivalent to the behavior estimation system 1 of the present embodiment can be realized without using the dedicated server 101 or the like.

  That is, the behavior estimation method has a first step, a second step, a third step, and a fourth step. A 1st step is a step which acquires the information (locking / unlocking information D1) regarding the change of the state of the electric lock 3 which locks the opening part of the consumer facility 2. As shown in FIG. The second step is a step of acquiring information (specific information D2) for specifying an individual who has changed the state of the electric lock 3. The third step is a step of acquiring information related to power consumption (power information D3) in the customer facility 2. The fourth step is a step of estimating the behavior of the estimation target person who is an individual identified from the information acquired in the second step based on the information acquired in the first step, the second step, and the third step. is there.

  Also, according to the predetermined program, the behavior estimation method can be executed by a computer. In other words, the program here is a program for causing a computer to execute the behavior estimation method. That is, the behavior estimation method is a method for causing a computer to perform the first step, the second step, the third step, and the fourth step. The program may be recorded in advance in the memory of the computer, but is not limited to this example, and may be provided through an electric communication line or may be provided by being recorded on a recording medium such as a memory card.

  Next, a control method of the information terminal 6 that is used in the behavior estimation system 1 and receives the estimation result of the estimation unit 14 from the output unit 15 will be described. That is, the control method of the information terminal 6 includes a step of receiving the estimation result of the estimation unit 14 (reception step) and a step of displaying the estimation result of the estimation unit 14 on the display unit 61 of the information terminal 6 (display step). Have. Thereby, the information terminal 6 can receive the estimation result of the estimation unit 14 and present the estimation result of the estimation unit 14 to the resident who has the information terminal 6 by the display of the display unit 61.

  Moreover, it is preferable that the control method of the information terminal 6 further includes a step (contact step) of displaying information for contacting the estimation target person on the display unit 61. For example, the information terminal 6 displays on the display unit 61 an icon for making a call to a mobile phone possessed by the person to be estimated or a telephone number of the mobile telephone possessed by the person to be estimated. Thereby, the resident who has the information terminal 6 can contact an estimation object person easily. The information for contacting the estimation target person displayed on the display unit 61 may be an icon for transmitting a standard message such as “Return” or “There is a snack”. However, the information terminal 6 can only display information for contacting the estimation target person on the display unit 61, and can execute the contact to the estimation target person by using the operation of the resident who holds the information terminal 6 as a trigger. preferable. Thereby, in an estimation object person, it can confirm that the resident who has the information terminal 6 saw notification.

  The information terminal 6 is controlled by the above control method by installing dedicated application software and starting the application software. That is, according to the predetermined program, the computer can execute the control method of the information terminal 6. In other words, the program here is a program for causing a computer to execute the control method of the information terminal 6. The control method of the information terminal 6 is a method for causing a computer to perform a reception step, a display step, and a contact step. The program may be recorded in advance in the memory of the computer, but is not limited to this example, and may be provided through an electric communication line or may be provided by being recorded on a recording medium such as a memory card.

(3) Effect According to the behavior estimation system 1 described above, the estimation unit 14 estimates the behavior of the estimation target person based on the three types of information D1, D2, and D3. Since the estimation target person is an individual specified from the specific information D2 acquired by the second acquisition unit 12, it is an individual who has changed the state of the electric lock 3, that is, an individual who has locked or unlocked the electric lock 3. . Therefore, the estimation unit 14 targets an individual who locks or unlocks the electric lock 3 (a person to be estimated), and further lock / unlock information D1 regarding the change in the state of the electric lock 3 and power related to the power consumption of the customer facility 2. Using the information D3, it is possible to estimate the behavior of the estimation target person. Therefore, in the behavior estimation system 1, it is possible to estimate the behavior of a specific person, for example, in the home where the child is present, such as the child returning home or the mother going out. Therefore, according to the behavior estimation system 1, there is an advantage that the situation of the target person (estimation target person) can be estimated in more detail than the configuration in which the resident's home, absence, or abnormality is simply determined. is there.

  Moreover, in the behavior estimation system 1, since the estimation part 14 judges whether a person exists in the consumer facility 2 based on the electric power information D3 which the 3rd acquisition part 13 acquired, an estimation object person is It is possible to estimate whether or not the customer facility 2 exists. Therefore, for example, when the communication method between the electric lock 3 and the key device 4 is Bluetooth (registered trademark) or the like, the behavior estimation system 1 is particularly useful. That is, in such a case, it may not be possible to determine whether the electric lock 3 has been operated from within the customer facility 2 or from outside the customer facility 2 only by the locking / unlocking information D1. The estimation unit 14 can accurately estimate whether the estimation target person has entered the customer facility 2 or the customer facility 2 by combining the locking / unlocking information D1 and the power information D3.

  Further, as in the present embodiment, the information D1 acquired by the first acquisition unit 11 is any of a plurality of change patterns in which the change in the state of the electric lock 3 includes the first pattern and the second pattern. It is preferable that the information represents. The first pattern is a pattern representing a change of the electric lock 3 from the locked state to the unlocked state. The second pattern is a pattern representing the change of the electric lock 3 from the unlocked state to the locked state. According to this configuration, the change from the locked state of the electric lock 3 to the unlocked state and the change of the electric lock 3 from the unlocked state to the locked state are estimated from the information D1 acquired by the first acquisition unit 11. The part 14 is distinguishable. Therefore, the estimation accuracy of the estimation target person's action in the estimation unit 14 is improved. However, this configuration is not essential for the behavior estimation system 1 and may be omitted as appropriate.

  Further, as in the present embodiment, the estimation unit 14 acquires the information D1 representing the first pattern by the first acquisition unit 11, and the power consumption of the customer facility 2 exceeds a predetermined threshold during the first monitoring period. It is preferable to estimate that the estimation target person has moved from outside the customer facility 2 into the customer facility 2. The first monitoring period here is a period from when the information D1 representing the first pattern is acquired until a predetermined time elapses. According to this configuration, the estimation unit 14 can estimate, as an estimation target person's action, that the estimation target person returns home, that is, that the estimation target person has moved from outside the customer facility 2 into the customer facility 2. . However, this configuration is not an essential configuration for the behavior estimation system 1, and the function of estimating the estimation subject's return home as the behavior of the estimation subject may be omitted as appropriate.

  In this case, as in the present embodiment, the estimation unit 14 is configured to estimate that the estimation target person has gone to bed when the power consumption of the customer facility 2 falls below a predetermined threshold during the second monitoring period. It is preferable. The second monitoring period here is a period after estimation that the estimation target person has moved from outside the customer facility 2 into the customer facility 2. According to this configuration, the estimation unit 14 can estimate the sleep of the estimation target person as the behavior of the estimation target person. However, this configuration is not essential for the behavior estimation system 1, and the function of estimating the estimated subject's sleep as the behavior of the estimation subject may be omitted as appropriate.

  Further, as in the present embodiment, the estimation unit 14 acquires information indicating the second pattern by the first acquisition unit 11 and when the power consumption of the customer facility 2 is equal to or less than a predetermined threshold during the third monitoring period. It is preferable to estimate that the estimation target person has moved from the customer facility 2 to the outside of the customer facility 2. The third monitoring period here is a period from when the information D1 representing the second pattern is acquired until a predetermined time elapses. According to this configuration, the estimation unit 14 can estimate, as the estimation target person's behavior, that the estimation target person has gone out, that is, that the estimation target person has moved from the customer facility 2 to the outside of the customer facility 2. . However, this configuration is not an essential configuration for the behavior estimation system 1, and the function of estimating the estimation subject person's going out as the behavior of the estimation subject person may be omitted as appropriate.

  When the first acquisition unit 11 acquires the information representing the first pattern and the information D1 representing the second pattern within a certain time, the estimation unit 14 is information D3 regarding the power consumption of the customer facility 2 in the fourth monitoring period. Based on the above, it may be estimated whether or not the estimation target person exists in the customer facility 2. The fourth monitoring period here is a period from when the information representing the first pattern and the information representing the second pattern are acquired until a predetermined time elapses. According to this configuration, the estimation unit 14 can estimate the temporary return of the estimation target person and the primary outing as the behavior of the estimation target person. However, this configuration is not essential for the behavior estimation system 1, and the function of estimating the estimation target person's temporary return and primary outing as the estimation target person's behavior may be omitted as appropriate.

  Moreover, like this embodiment, the 3rd acquisition part 13 is related with power consumption about each of the some individual circuit 91,92,93 matched with the some person who uses the consumer facility 2 on a one-to-one basis. It is preferable to acquire information D3. In this case, the estimation unit 14 may estimate the behavior of the estimation target person based on information on the power consumption of the individual circuit corresponding to the estimation target person among the information D3 acquired by the third acquisition unit 13. preferable. According to this configuration, the estimation unit 14 can identify not only the individual who operates the electric lock 3 but also the individual who uses the electrical load in the customer facility 2. The estimation accuracy of is improved. For example, even when a plurality of residents go home with a time interval, the estimation unit 14 can distinguish each person who first came home from the second person who came home and estimate each action. However, this configuration is not an essential configuration for the behavior estimation system 1, and the third acquisition unit 13 acquires information D <b> 3 related to power consumption in the entire customer facility 2, not for each of the plurality of individual circuits 91, 92, 93. May be.

  Moreover, it is preferable that the action estimation system 1 is further provided with the output part 15 which outputs the estimation result of the estimation part 14 like this embodiment. According to this configuration, the estimation result of the estimation unit 14 can be confirmed on the information terminal 6, for example. However, this configuration is not essential for the behavior estimation system 1, and the output unit 15 may be omitted as appropriate.

  In this case, as in the present embodiment, the output unit 15 corresponds to an individual other than the person to be estimated among the plurality of information terminals 6 associated one-to-one with a plurality of people who use the customer facility 2. It is preferable to output the estimation result of the estimation unit 14 to at least one information terminal 6 that performs. According to this configuration, the behavior of the estimation target person estimated by the estimation unit 14 is notified to an individual other than the estimation target person, not the estimation target person himself. It becomes possible to do. However, this configuration is not essential for the behavior estimation system 1, and the output unit 15 may output the estimation result of the estimation unit 14 to the information terminal 6 corresponding to the estimation target person.

  Moreover, like this embodiment, it is preferable that the control method of the information terminal 6 that is used in the behavior estimation system 1 and receives the estimation result of the estimation unit 14 from the output unit 15 includes a reception step and a display step. . The reception step is a step of receiving the estimation result of the estimation unit 14. The display step is a step of displaying the estimation result of the estimation unit 14 on the display unit 61 of the information terminal 6. According to this method, the information terminal 6 can receive the estimation result of the estimation unit 14 and present the estimation result of the estimation unit 14 to the resident who has the information terminal 6 by the display of the display unit 61.

  In this case, it is preferable that the control method of the information terminal 6 further includes a step of causing the display unit 61 to display information for contacting the estimation target person. According to this method, the resident having the information terminal 6 can easily contact the estimation target person.

  The behavior estimation method has a first step, a second step, a third step, and a fourth step. The first step is a step of acquiring information D1 relating to a change in the state of the electric lock 3 that locks the opening of the customer facility 2.
