<Composition of event information>
In the present embodiment, event information 90 having user behavior information 92 is used to determine whether the user is at home or away. FIG. 4 is a diagram illustrating an example of the event information 90 according to the first embodiment.

  Referring to FIG. 4, event information 90 includes, for each user, a name 91 that is an identifier of the user and action information 92.

  The behavior information 92 includes behavior content 93 indicating the content of the user's behavior (including scheduled behavior content) and time data 94 associated with the behavior content 93. The time data 94 indicates the date and time when the action indicated by the action content 93 is performed (or scheduled to be performed).

  Desirably, the time data 94 represents a time divided into units of one hour, and the action content 93 corresponds to each time (one hour) of the associated time data 94 (or an action (or time) performed at the time. , The action scheduled for implementation). The action content 93 is indicated by a character string (character string such as at-home, commuting, school attendance, etc.) representing the action content. The action content 93 may be indicated by a pattern (for example, a train pattern, a school pattern, etc.) representing the content of the action instead of the character string or together with the character string.

  In the present embodiment, the event information 90 is stored in a rewritable nonvolatile storage area in the storage unit (RAM 73 or HDD 74) of the server device 70, but the storage location is not limited to the storage unit. Further, the user operates a terminal (for example, the smartphone 63 or the tablet terminal 40) in order to read information from the event information 90 or to change (rewrite) information to the event information 90. The terminal communicates with the server device 70 in accordance with a user operation.

  The event information 90 is not limited to the format shown in FIG. 4 as long as the behavior information 92 is registered in association with each user. Further, although the behavior information 92 for three people is registered in the “good” in FIG. 4, the behavior information 92 to be registered may be for four or more people.

<Functional configuration>
FIG. 5 is a diagram illustrating a configuration of functions for managing behavior information according to the first embodiment. Referring to FIG. 5, server device 70 has information acquisition unit 81 that acquires user behavior information, behavior determination unit 82, power determination unit 83, and results of each determination by behavior determination unit 82 and power determination unit 83. A coincidence determination unit 84, a detection unit 85, and an output unit 86 are provided for determining whether or not they match.

  The information acquisition unit 81 searches the event information 90 based on the time data from the timer 87, and reads the user behavior information 92 based on the search result.

  The behavior determination unit 82 determines whether or not the user is in the home based on the behavior content 93 at a predetermined time in the behavior information 92 read by the information acquisition unit 81. Specifically, when the action content 93 is indicated by a character string, a word is extracted from the character string, and based on the extracted word, first dictionary data (not shown) stored in the HDD 74 and Second dictionary data (not shown) is searched. Here, a plurality of words associated with “at home” (for example, “at home” and “sleeping”) are registered in the first dictionary data, and “absence” is associated with the second dictionary data. Words (for example, “attendance”, “shopping”, “school”, etc.) are registered. If the action determination unit 82 determines that the extracted word is registered in the first dictionary data based on the search result, the action determination unit 82 determines that the user is “at home”, and the second If it is determined that it is registered in the dictionary data, it is determined that it is “absent”. Note that the home / absence determination method by the behavior determination unit 82 is not limited to this.

  The detection unit 85 detects the amount of power consumption in the user home 20. Specifically, the detection unit 85 receives data of power consumption (unit: kW) measured at the user's home 20 from the HEMS controller 30 and performs the above-described integration process on the received power consumption data. .

  The power determination unit 83 compares the power consumption amount for a predetermined time detected by the detection unit 85 with a threshold value, and acquires a change in power consumption from the comparison result. The power determination unit 83 determines whether the user is at home or not at the predetermined time based on the change in power consumption.

  The coincidence determination unit 84 determines whether or not the determination result by the behavior determination unit 82 matches the determination result by the power determination unit 83.

  The output unit 86 transmits information based on the above-described determination result (match or mismatch) of the match determination unit 84 to the terminal of the user or the sharer (smart phone 63 or tablet terminal 40). In the present embodiment, the “sharer” is a person who can share the behavior information 92 of the user. More specifically, the “sharer” is a person who is permitted to read the user behavior information 92 from the event information 90.

  For example, when the above-described determination result of the coincidence determination unit 84 indicates “non-coincidence”, the output unit 86 determines that the action determination unit 82 is “absent” based on the user action content 93, and the power determination unit If 83 is determined to be “at home” based on a change in power consumption, it outputs information for prompting confirmation of whether or not the behavior information 92 needs to be changed. For example, the output unit 86 outputs a message (hereinafter also referred to as a confirmation request message) “The user's action content is different from the registered action information. Please check the registered action information”. . As a case corresponding to this case, for example, there is a case where the user sets the behavior information 92 for a certain time to “absent”, but the user actually watches the television at home at that time.

  Further, as another case where the above-described determination result of the coincidence determining unit 84 indicates “non-coincidence”, the behavior determining unit 82 determines “at home” based on the user's behavior content 93, and the power determining unit 83 uses the power consumption. In some cases, it may be judged “absent” based on changes in Also in this case, the output unit 86 outputs a confirmation request message to prompt confirmation of whether or not the behavior information 92 needs to be changed. In this case, for example, the user has set the behavior information 92 for a certain time to “at home”, but the user is actually going out with the TV turned off at that time.

  Thus, when the determination result of the match determination unit 84 indicates “mismatch”, the server device 70 can prompt the user to change the action information 92 to match the actual action content. .

  On the other hand, when the above-described determination result of the coincidence determination unit 84 indicates “coincidence”, that is, the behavior determination unit 82 determines “at home” based on the user's behavior content 93, and the power determination unit 83 changes the power consumption. If it is determined that the user is “at home” based on the information, the output unit 86 outputs information indicating that the behavior information 92 matches the actual behavior content of the user. When the above-described determination result of the coincidence determining unit 84 indicates “match”, the output unit 86 can omit the output of the information.

  The output part 86 transmits the said information to the user's or a sharer's smart phone 63 or the tablet terminal 40 via communication IF77 as an aspect of output of said information. The smartphone 63 or the tablet terminal 40 displays the information received from the output unit 86 on the display or outputs the information by voice. Moreover, the smart phone 63 or the tablet terminal 40 changes the output mode of information according to the content of the received information.

  Note that the output of information by the output unit 86 is not limited to transmission to a terminal such as the smartphone 63 or the tablet terminal 40, and information may be stored in a storage unit such as the HDD 74.

Further, the information output by the output unit 86 is not limited to the above message.
The function of each unit of the server device 70 in FIG. 5 is realized by each hardware and software (program and data) executed by the CPU 71. Such software may be stored in the HDD 74 in advance. The software may be stored in other storage media and distributed as a program product. Alternatively, the software may be provided as a program and data that can be downloaded by an information provider connected to the so-called Internet. Such software is read from the storage medium by the reading device or downloaded via the communication IF 77 and the like, and then temporarily stored in the HDD 74. The software is read from the HDD 74 by the CPU 71 and stored in the RAM 73 in the form of an executable program. The CPU 71 executes the program.

<Processing>
FIG. 6 is a flowchart of information processing according to the first embodiment. With reference to FIG. 6, information processing based on user behavior information and in-home power consumption will be described. The program according to the flowchart of FIG. 6 is stored in advance in the storage unit (ROM 72, HDD 74, etc.) of the server device 70. The CPU 71 reads the program from the storage unit and executes the read program to realize information processing.

  Here, information as shown in FIG. 4 is registered in the event information 90. In addition, the HEMS controller 30 transmits data of power consumption (unit: kW) of the electric device 10 </ b> B (television) measured by the power measuring instrument 20 </ b> B to the server device 70. In the process of FIG. 6, the user is “Taro” in FIG. 4, and the sharers of Taro's behavior information 92 are “Hanako” and “Jiro” in FIG. 4.

  Referring to FIG. 6, first, CPU 71 determines whether or not an operation for setting information on a sharer is performed by a user (step S <b> 5). If it is determined that the operation is not performed (NO in step S5), the process ends. On the other hand, when the CPU 71 determines that the user has performed an operation for setting information of the sharer (YES in step S5), the CPU 71 sets information based on the operation content. Specifically, the user operates the smartphone 63 to transmit the address information of the user's terminal and the address information of each sharer's terminal to the server device 70. The CPU 71 stores the received address information in a non-volatile area of the storage unit (RAM 73, HDD 74). Thereby, information (address information of the user's terminal and address information of each sharer's terminal) specifying the output destination of information by the output unit 86 is set.

  The CPU 71 starts measuring a predetermined time based on the time data of the timer 87 (step S13). The predetermined time indicates the length of time for which the power consumption in the user home 20 is integrated. Here, the predetermined time is, for example, 2 hours.

  The CPU 71 performs the calculation of the power consumption and the determination of “at home” or “absence” based on the calculated power consumption during the two hours (during the period until NO is determined in Step S19) (Step S19). S15 to S23). Here, the predetermined time is divided into unit times (for example, one hour) shorter than the predetermined time, and the power consumption is calculated for each unit time.

  Specifically, the CPU 71 integrates the power consumption indicated by the data received from the HEMS controller 30 over a unit time (1 hour) as the detection unit 85, and stores the integrated value in the RAM 73 (steps S15 and S17). When the CPU 71 determines that a predetermined time (2 hours) has elapsed based on the time data of the timer 87 (YES in step S19), the CPU 71 ends the measurement of the elapse of the predetermined time (step S20). . At this time, the RAM 73 stores the power consumption data (this is also referred to as first power consumption data), which is an integrated value of the first unit time (for one hour), and the next unit time (for the next one hour). ), Which is an integrated value of the power consumption (which is also referred to as second power consumption data).

  The power determining unit 83 compares the power consumption amount indicated by the first power consumption data in the RAM 73 with the first threshold value, and based on the comparison result, whether the television is in the on state or the off state in the first hour period. Judging. Similarly, the power consumption amount indicated by the second power consumption data in the RAM 73 is compared with the first threshold value, and based on the comparison result, whether the television is in the on state or the off state in the next one hour period is determined. to decide. Further, the power determining unit 83 determines “at home” or “absent” based on the change in the state (step S21).

  Here, the background of the present embodiment will be described. For example, when a TV power switch is turned ON / OFF by a user operation, the power consumption of the TV changes. In other words, if the power consumption of the TV changes between 1 hour from 6:00 to 7:00 and the next hour from 7:00 to 8:00, the user at home turns on / off the TV. By doing so, it can be determined that the state of the television has been switched. Based on such a background, when the power determining unit 83 determines that the state of the television has changed, that is, there is a change in the power consumption, the user determines that the user is “at home” and the state of the television changes. If it is determined that there is no change in power consumption, the user determines that the user is “absent”.

  The first threshold value represents the standby power consumption of the television, and is stored in a non-volatile storage area or the like of the server device 70. In addition, the above “OFF state” indicates that the TV is turned off (power switch OFF) but is in a standby state that consumes power, and the “ON state” indicates that the TV is turned on (power switch ON). ), Indicating a non-standby state that requires more power than standby power consumption.

  Thus, the power determination unit 83 determines “at home” or “absence” based on the change between the on state and the off state of the television, that is, based on the change in power consumption (step S21).

  Based on the information from the information acquisition unit 81, the behavior determination unit 82 determines whether the user is “at home” or “absent” at the predetermined time (step S23). Specifically, the information acquisition unit 81 reads the action content 93 associated with the time data 94 indicating the predetermined time of the user action information 92 from the event information 90. Based on the read action content 93, the action determination unit 82 determines whether or not the user is in the house, that is, “at home” or “absent”. The determination result is stored in the RAM 73.

  The coincidence determination unit 84 determines whether or not the determination result of step S21 by the power determination unit 83 matches the determination result of step S23 by the behavior determination unit 82 (whether or not they are contradictory) (step S25). .

  If coincidence determination unit 84 determines that the determination results of power determination unit 83 and action determination unit 82 match (no contradiction) (YES in step S25), the process returns to step S13, and the following predetermined determination is made. For the given time (for the next two hours), the processing after step S13 is repeated in the same manner as described above.

  On the other hand, when the coincidence determination unit 84 determines that the determination results of the power determination unit 83 and the behavior determination unit 82 do not match (there is a contradiction) (NO in step S25), the output unit 86 displays the user in step S5. Using the address information set based on the operation, the above confirmation request message is transmitted to the user terminal (step S27).

  The user (Taro) can confirm the received confirmation request message with the terminal. The user operates the terminal according to the confirmation request message. The terminal communicates with the server device 70 according to the operation content. Based on data from the terminal, the CPU 71 of the server device 70 changes (rewrites) the user behavior information 92 in the event information 90 to represent the actual behavior content of the user.

  After the process of step S27, the CPU 71 of the server device 70 reads the behavior information 92 corresponding to the user's predetermined time from the event information 90 (step S29). The CPU 71 compares the read action information 92 with the determination result (“at home” or “absent”) in step S23. Based on the comparison result, the CPU 71 determines whether or not the behavior information 92 has been changed to indicate the determination result (“at home” or “absence”) in step S23 (step S31). If the CPU 71 determines that the action information 92 has been changed (YES in step S31), the process returns to step S13, and the process after step S13 is performed for the next predetermined time (for the next two hours). Is repeated in the same manner as described above.

  On the other hand, when the CPU 71 determines that the behavior information 92 read in step S29 has not been changed to indicate the result of determination in step S23 ("at home" or "absent") (NO in step S31). ), CPU 71 outputs information to each sharer's terminal (step S33).

  Specifically, the CPU 71 uses the address information of each sharer set based on the user operation in step S5 as the output unit 86 to register the action content of the above confirmation request message “user (Taro)”. "Please check the registered behavior information." Is sent to each sharer's terminal (step S33). Thereafter, the CPU 71 ends the process of FIG.

  Each sharer's smartphone 63 receives the confirmation request message transmitted from the server device 70 in step S33, and displays the received confirmation request message. Each sharer (Hanako, Jiro) can prompt the user (Taro) to change the behavior information 92 verbally or through communication between terminals based on the displayed confirmation request message.

  Therefore, when a confirmation request message is transmitted from the server device 70 to the user's terminal in step S27, even if the user does not change the behavior information 92 according to the confirmation request message (not rewritten), the user can share The person is prompted to change the action information 92.

  As described above, according to the processing of FIG. 6, the server device 70 can manage the user behavior information 92 so as to indicate the actual behavior content of the user.

  In FIG. 6, after the server device 70 outputs a confirmation request message to each sharer in step S <b> 33, a series of processing is terminated. However, the termination method is not limited to this. For example, after the process of step S33, the process returns to step S13, and the process after step S13 may be repeated in the same manner as described above for the next predetermined time (for the next two hours).

  Alternatively, the process of FIG. 6 may be repeatedly executed at regular time intervals (a period longer than a predetermined time). For example, when the fixed time is 48 hours, the process of FIG. 6 is repeatedly executed during the period from the start of the process of FIG. 6 to the lapse of 48 hours. The fixed time is variably set by the user.

(Processing of coincidence determination unit 84 and output unit 86)
A specific example of each process of the coincidence determination unit 84 and the output unit 86 will be described.

  Here, the process will be described separately when the coincidence determination unit 84 determines that the determination results of the action determination unit 82 and the power determination unit 83 match each other and when it determines “disagreement”. For the sake of explanation, the above-mentioned predetermined time is a period of 2 hours in total, which is 1 hour from 6 o'clock to 7 o'clock and the next hour from 7 o'clock to 8 o'clock. Further, it is assumed that the user (Taro), the sharer (Hanako), and another sharer (Jiro) live in different houses.

  (1) First, a case where the coincidence determination unit 84 determines that the determination results of the behavior determination unit 82 and the power determination unit 83 match each other will be described.

  (1-1) In this case, as an example, the behavior information 92 of the user at a predetermined time indicates “at home”, and the power determination unit 83 indicates that the power consumption has changed during the predetermined time. Yes, that is, the case where the user determines “at home” is included.

  (1-2) Also, in this case, as another example, the user rewrites the behavior information 92 in the order of “at home” → “absent” → “at home” in accordance with actual behavior at a predetermined time, The power determination unit 83 includes a case where there is a change in power consumption at a predetermined time, that is, the user determines “at home”. In addition, when the user rewrites the behavior information 92 in the order of “at home” → “absent” → “at home” as described above within a predetermined time, for example, sharing during the action with the user The case where the user rewrites the behavior information 92 by prompting the user to rewrite the behavior information 92 is included.

  In the cases (1-1) and (1-2) above, the determination results (“at home”) of the behavior determination unit 82 and the power determination unit 83 match, so that the behavior information 92 need not be changed. Therefore, the confirmation request message is not output.

  (2) Next, a case will be described in which the coincidence determination unit 84 determines that the determination results of the action determination unit 82 and the power determination unit 83 do not match.

  (2-1) This case includes, as an example, a case where the behavior information 92 cannot be changed so as to indicate the actual behavior of the user because the user has lost the smartphone 63.

  (2-2) In this case, as another example, the user's state is such that the smartphone 63 cannot be operated (that is, the behavior information 92 cannot be changed to indicate the actual content of the user's behavior). ) In case of emergency. The emergency state includes, for example, that the user is sick or the user is dead.

  In the cases (2-1) and (2-2) above, the determination results of the behavior determination unit 82 and the power determination unit 83 do not match, so the user behavior information 92 is changed to indicate the actual behavior content. There is a need to. Therefore, the output unit 86 transmits the confirmation request message to the user terminal or each sharer terminal.

  In the present embodiment, the server device 70 performs the power consumption integration process. However, instead of the server device 70, the HEMS controller 30 may execute the integration document. In that case, the detection unit 85 receives power consumption data from the HEMS controller 30, and stores the power consumption data in the RAM 73 in association with the time data from the timer 87.

  6 is performed in the server device 70, so even if the power plug of the HEMS controller 30 is disconnected from the outlet 30A, the information from the output unit 86 is transmitted to the server device 70 → the network 60 → It can be transmitted via the route of MME 61 → base station device 62 → smart phone 63.

  6 may be performed in a relay device between the HEMS controller 30 and the server device 70 of the communication system 1 instead of the server device 70.

  The output unit 86 may transmit a confirmation request signal together with the confirmation request message to the user or the sharer's terminal instead of the confirmation request message. Upon receiving the confirmation request signal from the output unit 86, the user or the sharer terminal may display a predetermined icon on the screen or output a predetermined sound based on the received confirmation request signal. .

[Embodiment 2]
The second embodiment shows a modification of the process of FIG. In the process of the first embodiment, when the match determination unit 84 determines that the determination results of the behavior determination unit 82 and the power determination unit 83 do not match (NO in step S25 in FIG. 6), the user or the share A confirmation request message has been sent to the user's terminal. In the second embodiment, instead of the method of uniformly transmitting the confirmation request message as in the first embodiment, a method in which the case of transmitting the confirmation request message is limited will be described.

  In the second embodiment, the output unit 86 needs to change the behavior information 92 only when the determination result of the behavior determination unit 82 indicates “absent” and the determination result of the power determination unit 83 indicates “at home”. A confirmation request message for prompting confirmation of whether or not is transmitted to the terminal of the user or the sharer.

  Thereby, only when a change in power consumption in the home is detected at the time when it is determined from the behavior information 92 that the user is absent, that is, an abnormality that power is consumed in the home when the user is absent. Only when a state is detected, a confirmation request message for prompting confirmation of the behavior information 92 can be transmitted to the user terminal.

[Embodiment 3]
The third embodiment shows a modification of the second embodiment. Also in the third embodiment, the confirmation request message is transmitted to the user or the sharer's terminal in a case where a change in power consumption is detected when the user is away from home. In the third embodiment, after the terminal receives the confirmation request message, when the CPU 71 determines that the user behavior information 92 is not changed, the CPU 71 determines that there is an abnormality in the absence. Based on this determination, the CPU 71 uses the output unit 86 to display a message for alerting the user, “I should be absent, but the power consumption is changing. Send to sharer's device.

  Thus, in a case where a change in power consumption is detected when the user is away from the home, for example, in a case where a suspicious person is assumed to have entered the home, the CPU 71 may Send a message to call attention. The user confirms the message for calling attention through the terminal. Thereby, it can prevent that a user overlooks the abnormal state in a house.

[Embodiment 4]
The fourth embodiment shows a modification of the first to third embodiments. In each of the above embodiments, the behavior determination unit 82 determines “at home” or “absence” at a predetermined time from the behavior information 92 acquired by the information acquisition unit 81. The method of acquiring behavior information is not limited to this.

  That is, for example, information based on the user operating a physical switch may be used as the user behavior information. Specifically, the user switch 20 is provided with a physical switch 65 (see FIG. 1) including a switch configured with an electric circuit. The user operates the switch 65 to turn off (open) when going out, and turns the switch 65 on (closed) when returning from going out. Alternatively, the reverse operation may be performed. The HEMS controller 30 detects a change in the state (open, closed) of the switch 65 and transmits information including the detection result to the server device 70. This information includes user operation content indicating a change in the state (open, closed) of the switch 65 and time data indicating a time when the user operation content is detected. This time data is indicated by time data from the timer 34. The switch 65 is an example of an “operation receiving unit” that receives user operation content.

  The information acquisition unit 81 of the server device 70 includes information based on the user operation content of the switch 65 from the HEMS controller 30 (that is, the user operation content indicating a change in the state (open, closed) of the switch 65 and the user operation content). Based on the information including the time data indicating the detected time), the action content 93 associated with the time data indicating the predetermined time is generated. This action content 93 is information indicating either “at home” corresponding to the open state of the switch 65 of the user or “absence” corresponding to the closed state.

  More specifically, when the user switches the switch 65 to OFF (open) when going out, the switch 65 outputs an absence start signal indicating the absence start. Further, when the user switches the return switch 65 on (closed) after going out, the switch 65 outputs an absence end signal indicating the absence end. The CPU 71 of the server device 70 measures the time when the absence start signal is received and the time when the absence end signal is received via the HEMS controller 30 by the timer 87, and based on the measured time, the user's home time and absence time are measured. calculate.

  The CPU 71 generates, as the information acquisition unit 81, action content 93 from home or absence information based on the user operation content of the switch 65 from the HEMS controller 30, and generates time data 94 from the calculated home time and absence time. Generate. Then, action information 92 including the generated action content 93 and the time data 94 associated with the action content 93 is generated. Then, the CPU 71 registers the generated behavior information 92 in the event information 90.

  In the fourth embodiment, the determination result indicating “at home” or “absence” based on the user operation content received by the home operation reception unit (switch 65), and “at home” or “absence” based on the change in power consumption in the home Based on the determination result indicating “”, the output unit 86 transmits the confirmation request message to the user terminal or each sharer terminal.

  Further, when the switch 65 is operated according to the confirmation request message received by the user, the CPU 71 operates as the information acquisition unit 81 from information based on the operation content of the switch 65 from the HEMS controller 30 as described above. Action content 93 and time data 94 associated with the action content are generated. Then, the CPU 71 registers the generated behavior information 92 in the event information 90.

  As a result, even when “at home” or “absent” is determined based on the user operation content received by the in-home operation accepting unit (switch 65), the server device 70 stores the user behavior information 92 The action information 92 can be managed so as to indicate the actual action content.

[Embodiment 5]
The fifth embodiment shows a modification of the first to fourth embodiments. In each of the above embodiments, the power consumption of an electrical device (television) is measured in order to determine the state of the house, but the target for measuring the power consumption is not limited to the electrical device. For example, the power consumption may be measured for the entire user home 20 or for each room of the user home 20.

  Also in the fifth embodiment, as in the first to fourth embodiments, the output unit 86 determines the determination result “at home” or “absence” based on the user behavior information 92, the power consumption of the entire home, or the room unit. The confirmation request message is transmitted to the user terminal or each sharer terminal based on the determination result of “at home” or “absent” based on the change in power consumption.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
