  Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram showing an example of a building 100 provided with a message reproduction system 10 according to an embodiment of the present invention. As shown in FIG. 1, the message reproduction system 10 includes reproduction terminals 40A, 40B, 40C, and 40D having speakers for reproducing messages in the entrance 30, the living room 34, the child room 36, and the bedroom 38, respectively. ing.

  The reproduction terminals 40A, 40B, 40C, and 40D are connected to a HEMS (Home Energy Management System) 50 that can monitor the power consumption from the distribution board 52 to the building 100 and control the devices in the building 100, respectively. Yes. The connection between the playback terminals 40A, 40B, 40C, and 40D and the HEMS 50 may be wired connection using a LAN cable or the like, but may be connection using wireless communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark).

  The HEMS 50 controls the electric lock 32 </ b> A provided on the door 32 of the entrance 30. The electric lock 32A is a lock that can be locked and unlocked by the power of an electric actuator (not shown), and the operation of locking and unlocking stores ID information that is identification information of a resident who is a user. The electronic key 42 is used to transmit the ID information to the electric lock by wireless communication in response to communication from the communication unit of the electric lock 32A provided on the entrance door 32. The electric lock 32A is provided with a sensor (not shown) that detects that the door 32 has been opened and closed.

  The HEMS 50 locks and unlocks the electric lock 32A when the ID information received by the electric lock 32A from the electronic key 42 corresponds to a registered user such as a resident.

  The HEMS 50 is connected to a distribution board 52 to which system power that is commercial power is supplied from the outside. The HEMS 50 detects the amount of power supplied from the distribution board 52 to each of the living room 34, the child room 36, and the bedroom 38. The amount of electric power is, for example, a current sensor that detects an induced current generated in a power line from the distribution board 52 to each of the living room 34, the child room 36, and the bedroom 38, and detects a current of each power line based on the detected induced current. (Not shown). Electric power supplied from the distribution board 52 to each of the living room 34, the child room 36, and the bedroom 38 by multiplying the current value detected by the current sensor by a voltage value (for example, AC 100V) on the power line in the building 100. Calculate the amount. The HEMS 50 is connected to the cloud server 80 via the network 70.

  The cloud server 80 receives and registers the message transmitted by the resident who is the user using the portable information terminal 60 via the network 70. The message transmitted to the cloud server 80 includes ID information of the user who is the sender and ID information of the user who is the recipient of the message, in addition to the voice data which is the message. The ID information of each of the sender and the receiver may be typed directly from the portable information terminal 60, but it is desirable to simplify the message transmission work by using a dedicated application for message transmission.

  For example, when the name and ID information of a user such as a resident of the building 100 is stored in advance in the portable information terminal 60 and the above-described dedicated application is activated, the stored list of users is stored in the portable information terminal 60. A message displayed on the screen and registered for the user selected from the displayed list (a plurality of users can be simultaneously selected) may be registered in the cloud server 80.

  In the cloud server, the sender's ID information and the receiver's ID information are extracted from the message transmitted using the dedicated application, and registered in association with the voice data of the message. The message may be stored in the storage device of the HEMS 50 from the input unit of the HEMS 50 or may be registered in the cloud server 80 from the HEMS 50 via the network 70.

  The HEMS 50 acquires the message registered in the cloud server 80 via the network 70 when the returnee, who is the user who receives the message, unlocks the electric lock 32A and opens and closes the door 32, and reproduces the entrance 30 Play once on terminal 40A.

  Further, the HEMS 50 determines whether the returnee has heard the message reproduced on the reproduction terminal 40A of the entrance 30 based on the time from the unlocking to the locking of the electric lock 32A by the electronic key 42. For example, after the unlocking of the electric lock 32A by the electronic key 42, when the electric lock 32A is locked from the indoor side after a lapse of a specified time obtained by adding a certain time to the message reproduction time, the reproduction terminal 40A of the entrance 30 A response check is performed to determine that the returnee has heard the message reproduced in step 1. The fixed time in such a case is 30 to 60 seconds as an example.

  If the electric lock 32A is locked from the indoor side after the unlocking of the electric lock 32A with the electronic key 42 before the specified time has passed, the HEMS 50 returns a message reproduced by the reproduction terminal 40A of the entrance 30 to the homecoming person. Determine that you are not listening.

  When the HEMS 50 determines that the returnee has not heard the message reproduced at the reproduction terminal 40A of the entrance 30, the location of the returnee from the change in the power consumption of each of the living room 34, the child room 36, and the bedroom 38. And playback of the message is started at the playback terminal existing at the estimated location.

  FIG. 2 is a schematic diagram showing one aspect of a change in the power consumption of one place in the building 100 in the message reproduction system 10 according to the present embodiment. One place is one of the living room 34, the child room 36, and the bedroom 38 in FIG.

  As shown in FIG. 2, when the returnee comes home and turns on the lighting in any of the living room 34, the child room 36, and the bedroom 38, the power consumption at that place increases.

  In the HEMS 50, the place where the returnee is located in the living room 34, the child room 36, and the bedroom 38 where the power consumption increases and the increased power consumption exceeds the predetermined power consumption W for a predetermined time Δt. Estimated. The predetermined power amount W is, for example, the power consumption amount of the main lighting at each location or the total power consumption amount including the lighting at each location. The predetermined time Δt is about 5 to 10 seconds.

  The reproduction of the message at the reproduction terminal existing in the estimated location is terminated after being repeated a predetermined number of times, for example, three times. Alternatively, when a response confirmation indicating that the returnee has heard the message is made, the message reproduction is stopped before the prescribed number of reproductions.

  The response confirmation is determined from the estimated power consumption at the location of the returnee. For example, if the power consumption increases and becomes equal to or greater than the predetermined power amount W and then decreases to the predetermined power amount W or less after the lapse of the specified time ΔT, the returnee confirms the message and then turns off and leaves. Make a decision. The specified time ΔT is longer than the message playback time, and is 3 to 5 minutes as an example. Alternatively, the specified time ΔT may be a time obtained by adding a certain time to the message reproduction time, similar to the time required for confirming the message response at the entrance 30. The fixed time in such a case is 30 to 60 seconds as an example.

  Or, after the power consumption increases and becomes equal to or greater than the predetermined power amount W, if the state where the power consumption amount is equal to or greater than the predetermined power amount W continues for a specified time ΔT, then the power consumption amount is equal to the predetermined power amount. Even if the amount does not drop below the amount W, it may be determined that the returnee has confirmed the message.

  The response confirmation based on the timing of locking at the entrance 30 or the response confirmation based on the estimated change in the amount of power consumption at the home of the returnee is transmitted from the HEMS 50 to the cloud server 80 via the network 70, and the cloud server 80 Registered in The response confirmation registered in the cloud server 80 is transmitted to the portable information terminal 60 of the user who registered the message in the cloud server 80 using e-mail or the like.

  The CPU 12 governs the overall operation of the HEMS 50. The HDD 14 is a program for controlling the playback terminals 40A to 40D, a program for calculating power consumption, a program for estimating the whereabouts of the returnee based on the power consumption, an authentication program, a program for controlling the electric lock 32A, a cloud server 80 This is a non-volatile storage device in which a communication program, an OS (Operating System), data for execution of each program, and the like are recorded. The HDD 14 also stores identification information of a user such as a resident who is a registrant. The RAM 16 is a volatile storage device in which an OS, a program, or data is expanded. The network I / F unit 18 is for connecting to the network 70, and includes a NIC (Network Interface Card) and its driver. The ROM 20 is a nonvolatile storage device that stores a boot program that operates when the HEMS 50 is started. The display unit 22 displays information related to the message reproduction system 10 to the user. The operation input unit 24 is used when a user inputs an operation or information of the message reproduction system 10. As an example, an input device such as a touch panel and a keyboard and a pointing device such as a trackball, a pen tablet or a mouse, Includes a microphone for voice input. The bus 26 is used when information is exchanged.

  FIG. 4 is a flowchart showing an example of processing of the message reproduction system 10 according to the present exemplary embodiment. In step 300, the returnee unlocks the electric lock 32 </ b> A of the door 32 of the entrance 30 using the electronic key 42, and it is estimated that the returnee has entered the interior of the entrance 30 by opening and closing the door 32. .

  In step 302, the cloud server 80 is inquired to determine whether there is a message for the returnee. If the determination is affirmative, the message is reproduced on the reproduction terminal 40A of the entrance 30 in step 304. If the determination in step 302 is negative, the process ends.

  In step 306, it is determined whether the returnee has responded to the message. When the message is reproduced at the entrance 30, as described above, after the electric lock 32A is unlocked by the electronic key 42, the electric lock 32A is taken from the indoor side after a lapse of a specified time obtained by adding a certain time to the message reproduction time. When the message is locked, a response confirmation is made to determine that the returnee has heard the message.

  If the determination in step 306 is affirmative, the result of the response confirmation is stored in the HDD 14 of the HEMS 50, and the result of the response confirmation is transmitted to the cloud server 80, and the process ends.

  If a negative determination is made in step 306, it is determined in step 310 whether or not the number of message reproductions is within a specified number. If an affirmative determination is made, a place where the amount of power consumption has increased is searched in step 312. The prescribed number of times is 3 times as an example. If the determination in step 310 is negative, the process ends. In step 310, the message reproduction at the entrance 30 is not counted as the specified number of times.

  In step 314, it is determined whether or not the location of the returnee has been estimated. If the determination is affirmative, the message is reproduced at the location estimated in step 316. If the determination in step 314 is negative, the procedure returns to step 312.

  After playing the message in step 316, the procedure returns to step 306 to determine whether the returnee has responded to the message. As described above, the response confirmation in the message reproduction other than the entrance 30 increases rapidly after the specified time ΔT has elapsed after the estimated power consumption at the returnee's whereabouts increases and exceeds the predetermined power consumption W. This is the case when it falls.

  If the determination in step 306 is affirmative, the result of the response confirmation is stored in the HDD 14 of the HEMS 50, and the result of the response confirmation is transmitted to the cloud server 80, and the process ends.

  In the case of negative determination in step 306, the procedure is shifted to step 310, and it is determined again whether or not the number of message reproductions other than the entrance 30 is within the specified number of times. Play the message again.

  As described above, according to the present embodiment, whether or not the returnee has heard the message reproduced at the reproduction terminal 40A of the entrance 30 after unlocking the electrical lock 32A of the entrance 30 is determined. Is determined at the timing of re-locking. If the timing of re-locking is earlier than the reference, the returnee determines that he has left the entrance without listening to the message sufficiently.

  After that, a place where the amount of power consumption in the building 100 has increased is estimated as the place where the returnee is, and a message playback system capable of reliably transmitting the message to the returnee is provided by repeating the playback of the message at that place. It becomes possible.

  In the present embodiment, it is determined whether or not the returnee has heard the message based on the change in the power consumption at the place estimated to be the returnee's whereabouts, but each of the playback terminals 40A to 40D has the returnee's A microphone for detecting voice may be provided. Further, the HEMS 50 may have a voice recognition function, and may confirm the response based on the voices such as “OK” and “I understand” of the returnees detected by the microphones of the playback terminals 40A to 40D.
