  FIG. 1 shows the overall configuration of the present embodiment. In the figure, a controller, an operation terminal (display, audio output terminal), home electric appliances, sensors, and the like are connected by a home network. Each home appliance can be remotely operated by an operation terminal (display, audio output terminal) and a controller.

  The controller sequentially collects information regarding the operating state of each home appliance, output information of each sensor, and the like. Based on the collected information, the current status of the members (users) in the home is recognized, and for example, it is grasped whether the current status is sleeping or going out.

  Further, the controller is connected to the Internet or a telephone network, and when a mail is transmitted from outside the house, the controller notifies the operation terminal (display, voice output terminal) that the mail has been received.

  In the present embodiment, the mail sender adds information regarding the intention of the sender to the mail at the time of mail transmission. For example, (1) normal, (2) urgent, (3) not particularly urgent is selected, and this is added to the mail as intention information. On the other hand, as described above, the in-home controller grasps the receiver's situation, that is, (1) normal, (2) absent, (3) temporarily unable to respond (during cooking, etc.), (4) sleeping, etc. ing.

  When the controller receives the mail, the controller automatically selects an optimal notification method according to the intention information added to the mail and the current situation of the recipient, and transmits the message to the operation terminal. For example, if the sender's intention is urgent, the voice notification that makes the most attention is given regardless of the situation of the receiver. Alternatively, when the intention of the sender is not particularly urgent and the receiver is sleeping, the display terminal displays only so as not to disturb the bedtime.

  On the other hand, in a situation where the recipient is absent and it is unknown when the message is transmitted, the controller automatically notifies the sender of this situation. By such a reply notification, the sender can take measures such as changing the setting of the intention and transmitting again, or contacting other places by other communication means such as a telephone.

  An example of what kind of notification operation is performed according to the combination of the intention of the sender and the situation of the receiver is shown in FIG.

The output data holding unit 245 holds data necessary for audio output or the like.

  FIG. 5 shows a processing flow of notification processing executed by the controller 100 when a message is received.

  When the controller 100 receives a message (mail) via the Internet or the like (S101: YES), the sender setting identifying unit 122 analyzes the intention information included in the mail, and the setting of the mail is ( It is identified which one of (1) normal, (2) urgent, and (3) not particularly urgent (S102). Then, the receiver data collection unit 123 collects status information from each device (S103), and based on this, the recipient status recognition unit 124 recognizes the current status of the mail recipient (S104). Further, the controller 100 compares the table shown in FIG. 2 with the intention information identified in S102 and the recipient status recognized in S104, and selects a corresponding processing method in the controller 121 (S105). . Then, according to the selected processing method, notification to the operation terminal 200 or reply to the message transmission source is performed (S106 to S110).

  That is, if the selected processing method is notification to the operation terminal (S106: transmission) and this is a notification by voice (S107: voice notification), the communication interface 140 sends the operation terminal 200 corresponding to the recipient to the operation terminal 200. A message and a notification command by voice notification are transmitted (S108).

  If the selected processing method is notification to the operation terminal (S106: transmission) and this is notification by display (image) (S107: display), the communication interface 140 sends the operation terminal 200 corresponding to the recipient. On the other hand, a message and a notification command by display notification are transmitted (S109).

  If the selected processing method is a reply to the message sender (S106: reply notice), a reply notice indicating the recipient status (sleeping / absent) is sent from the communication interface 130 to the message sender ( S110).

  FIG. 6 shows a processing flow of processing executed on the operation terminal 200 when a message and a notification command are received from the controller 100.

  When the operation terminal 200 receives the message and the notification command via the home network (S201: YES), the notification command received together with the message is analyzed by the notification method identification unit 232 (S202), and the notification method is (1 It is identified which one of (2) notification by voice and (2) notification by display (S203).

  If the notification method is notification by voice (S203: voice notification), the corresponding incoming notification sound data is read from the output data holding unit 245, and the incoming voice is output from the voice output unit 244 (S204). If the notification method is notification by display (S203: display), the corresponding image data is read from the output data holding unit 245, and the incoming image is output from the display unit 243 (S205).

  Thereafter, when the user inputs opening of the message, the operation terminal 200 displays the received message on the display unit 243 (S206). If the operation terminal 200 is not turned off (S207: NO), the process returns to S201 and waits for reception of the next message.

  As described above, according to this embodiment, it is possible to transmit a message by an optimal notification method according to the intention on the message (mail) sender side and the situation on the receiver side. In addition, when the receiver cannot receive the message, the receiver's status is returned to the sender side, so that the sender side can smoothly grasp the status of the receiver side.

  In addition, in the said Example, each user hold | maintains RFID which transmits ID for identifying each person separately, and the human sensitive sensor distribute | arranged to each room detects RFID, Each user's Although the occupancy status is ascertained, the status of each user is predicted from the information on which room has people and the attribute information of the user such as age, gender, etc. without holding RFID individually. May be.

  For example, if the family consists of three mothers, fathers, and children, the presence sensor detects that there are people in the kitchen, and if the kitchen equipment is operating, the mother is cooking Recognize that At this time, if the human sensor detects that there is a person in the child's room and the clock is 7:00 pm, then the child will recognize that he is studying and that the person will be in the living room. If the sense sensor detects and the television is in operation, the remaining member, the father, recognizes that the television is being watched.

  In this way, when predicting the situation of each user from the information on which room the person is in and the attribute information of the user such as age, sex, etc., for example, the attribute information of the person (age, sex, Etc.), and an intelligent database that statistically determines who is in the room and what the person is doing from the room, day of the week, time zone, etc. Or it is necessary to equip the controller 100 with a processing algorithm. In this case, family members and their attribute information need to be registered in advance in the controller 100.

  Also, when only one member is present, specify the person who is present, and information (for example, information on the day of the week, the time zone, the room where each user resides, the operated equipment / lighting, etc.) By collecting and accumulating data, and calculating the correlation between each item and each user using a statistical method (multivariate analysis, etc.), the current situation of the user when a message arrives is predicted. Anyway. In this case, it is necessary to equip the controller 100 with an algorithm for predicting the user situation.

In the above, the received message and the notification command are transmitted to the operation terminal of the receiver. Instead, the room where the receiver is present is recognized from the detection result by the human sensor, A message and a notification command may be transmitted to the operation terminal in this room. In addition, when the transmission destination operation terminal for the message and the notification command is installed in a sleeping room, the transmission destination operation terminal may be changed to an operation terminal in a room where a person is present.

  The above embodiment is a case where message transmission by mail is performed, but in the present embodiment, the present invention is applied to message transmission using a telephone. That is, when the user who is sending a message makes a telephone call at home, if the user is sleeping, the user does not sound a ringing tone and returns a voice message to the calling telephone that is sleeping. Or at the time of an emergency call, a ringing tone is changed into emergency. With such a configuration, the same effect as the above-described message transmission by mail can be obtained in the telephone system.

  FIG. 7 shows functional blocks of the controller (IP telephone) 100 in such a case. Note that the functions in each functional block can be realized by, for example, mounting a program or database for causing the CPU in the controller 100 to execute these functions in the controller 100, as in the first embodiment.

  In the figure, the functions of the main processing unit 110 and the message processing unit 120 are the same as those in the first embodiment. In this embodiment, the intention information (emergency / normal / not particularly urgent) is set in accordance with, for example, a button operation after call control, and is transferred from the calling telephone to the controller 100. The sender setting identification unit 122 analyzes the information and recognizes the intention of the caller. Further, for example, a processing table shown in FIG. 8 is set in the control unit 121. The “reception side status” shown in the table indicates the status of all members. For example, the “reception side situation” is absent only when all members are absent, and is not absent if even one person is at home.

  The voice processing unit 150 performs voice processing during telephone communication. The control unit 151 performs main control during voice processing. The call control unit 152 performs control processing during call control. The voice input / output unit 153 performs voice input / output processing for the reception speaker, the speech microphone, and the ringing tone speaker. The audio codec unit 154 performs codec processing on the audio data according to the codec method set at the time of call control. The voice response unit 155 makes a voice response to the calling telephone.

  In this embodiment, when the controller 100 receives an incoming call and a call connection is established with the other party's telephone, the controller 100 first prompts the user to set intention information before outputting a ringing tone. The response is transmitted from the voice response unit 155 to the caller telephone. In response to this, when the caller user performs a button operation according to the intention information to be set, the intention information according to the button operation is transmitted from the caller telephone to the controller 100.

  The controller 100 analyzes the received intention information by the sender setting identification unit 122, and identifies whether the intention information is emergency / normal / particularly urgent. Furthermore, the receiver data collection unit 123 collects status information from each device, and based on this, the receiver status recognition unit 124 recognizes the current status of each member in the home. Further, the controller 100 uses the control unit 121 to check the intention information, the current status of each member in the home, and the processing table (FIG. 8), and selects a corresponding processing method. Then, according to the selected processing method, a ringing tone is output from the voice input / output unit 153, or a reply notification regarding the situation is transmitted from the voice response unit 155 to the caller telephone.

  As described above, according to the present embodiment, it is possible to make a call at an optimal call volume according to the intention of the calling party and the situation of the called party. Also, when the caller is unable to receive the call, the caller's status is sent back to the caller, so the caller can grasp the status of the caller smoothly. be able to.

  In the present embodiment, the urgency level is notified by changing the call volume, but the urgency level may be notified by other methods such as voice notification. In addition, a voice response that prompts the user to set intention information is sent to the caller only when a call is made from a pre-registered phone number. On the other hand, it is good also as calling at a normal volume similarly to the time of a normal telephone call, without receiving intention information.

As mentioned above, although embodiment which concerns on this invention was described, it cannot be overemphasized that this invention is not limited to this embodiment, and various changes are possible. The embodiments of the present invention can be appropriately modified in various ways within the scope of the technical idea shown in the claims.
