  The user may give the child device 300 a voice instruction for remotely operating the home appliance APL. The voice instruction is transmitted from the child device 300 to the parent device 200. Thereafter, the voice instruction is transmitted from the parent device 200 to the home appliance APL through the server SVR. The home appliance APL operates in response to a voice instruction. Therefore, the cordless telephone device 100 can function as a part of a system that executes a remote operation on the home appliance APL.

  The subunit | mobile_unit 300 contains the sound receiving part 310, the production | generation part 320, and the transmission part 330. FIG. The user emits sound toward the sound receiving unit 310. The sound receiving unit 310 receives sound and converts it into an electrical signal. The sound receiving unit 310 may be a microphone built in a general telephone. Alternatively, the sound receiving unit 310 may be another device that can convert a user's voice into an electrical signal. The principle of the present embodiment is not limited to a specific device used for the sound receiving unit 310.

  The electrical signal is output from the sound receiving unit 310 to the generation unit 320. The generation unit 320 performs an encoding process on the electrical signal and generates a stream representing the user's voice. In the present embodiment, the first generation unit is exemplified by the generation unit 320. The first stream is exemplified by the stream generated by the generation unit 320.

The transmission of the instruction bit information and the instruction stream from the transmission unit 330 to the parent device 200 uses a multiplexing scheme that is common to the stream generated by the generation unit 320 when the user does not give a trigger to the child device 300. The Therefore, an overly complicated design of the control system for controlling the home appliance APL is not required.

  The common multiplexing method established between the slave device 300 and the master device 200 may be a TDD-TDMA method compliant with the DECT standard. Alternatively, another multiplexing scheme may be established between the child device 300 and the parent device 200. The principle of this embodiment is not limited to a specific multiplexing method.

The telephone cordless handset described in connection with the fifth embodiment includes an operation mode between a first operation mode for talking with a call partner and a second operation mode for remotely operating a home appliance. Can be switched. Since the telephone handset transmits the call stream and the instruction stream to the base unit through a common multiplexing method, the user can perform the first operation while maintaining communication between the telephone of the other party and the telephone handset. The operation mode can be switched between the mode and the second operation mode. In the sixth embodiment, switching of the operation mode between the first operation mode and the second operation mode will be described.

  FIG. 6 is a schematic timing chart showing an exemplary operation of the telephone handset 300B. With reference to FIGS. 5 and 6, the operation of the telephone handset 300B will be described.

As a result, power is supplied from the power supply unit 350 to the signal conversion unit 310B and the integrated circuit 320B. Thereafter, the user operates the input key 311 to input the telephone number of the communication partner. As a result, the telephone of the communication partner is called from the telephone handset 300B. When the communication partner picks up the handset in response to the call, communication is established between the telephone handset 300B and the communication partner telephone. Thereafter, the telephone handset 300B operates in the first operation mode. While the telephone handset 300B is operating in the first operation mode, the user has a conversation with the other party. In the present embodiment, the call mode is exemplified by the first operation mode.

  At time T1 after time T0, the user presses power button 340B for a short period of time. As a result, a trigger signal is output from the power button 340B to the control unit 321.

The alternative stream may be transmitted from the control unit 321 to the parent device through the multiplexing method used for transmitting the instruction stream and the call stream.

  At time T2 after time T1, the user presses the power button 340B for a short period of time to request a return to the first operation mode. As a result, a new trigger signal is output from the power button 340B to the control unit 321. Therefore, when the encoding unit 322 is performing processing for generating an instruction stream, the control unit 321 receives a new trigger signal. The control unit 321 generates call bit information in response to a new trigger signal. In synchronization with the generation of the call bit information, the second operation mode (mute mode) ends, and the operation mode of the telephone handset 300B is switched from the second operation mode to the first operation mode. In the present embodiment, the second trigger is exemplified by a new trigger signal.

  The call bit information is output from the control unit 321 to the encoding unit 322. The encoding unit 322 starts an encoding process for generating a call stream according to the call bit information.

  As described in relation to the sixth embodiment, at time T1, the user operates the power button 340B. As a result, the operation mode of the telephone handset 300C is switched from the first operation mode to the second operation mode. The timer 324 is set with a predetermined setting period STL. The set period STL is long enough for the user to give a voice instruction to the home appliance.

  The telephone handset 300C operates in the second operation mode (mute mode) from the time T1 until the set period STL elapses. At time T2 after the set period STL from time T1, the timer 324 generates a notification signal that notifies the end of the set period STL. The notification signal is output from the timer 324 to the control unit 321C.

  The control unit 321C generates call bit information according to the notification signal. In synchronization with the generation of the call bit information, the second operation mode (mute mode) ends, and the operation mode of the telephone handset 300C is switched from the second operation mode to the first operation mode. The call bit information is output from the control unit 321C to the encoding unit 322. The encoding unit 322 starts an encoding process for generating a call stream according to the call bit information.

<Eighth Embodiment>
The technology described in relation to the various embodiments described above can be suitably used for a control system for controlling a home appliance. In the eighth embodiment, an exemplary control system is described.

  FIG. 8 is a conceptual diagram of a control system 400 according to the eighth embodiment. The control system 400 is described with reference to FIGS. 1, 4, 5 to 8.

  The control system 400 includes a cordless telephone device 101, a WiFi router 410, and a cloud server 420. The cordless telephone device 101 corresponds to the cordless telephone device 100 described with reference to FIG.

  The cordless telephone device 101 includes a master unit 201 and two telephone slave units 301 and 302. Each of the telephone slave units 301 and 302 may be designed based on the design principle of the telephone slave units 300B and 300C described with reference to FIGS.

  The call bit information, the call stream, the instruction bit information, and the instruction stream are transmitted from the telephone slave units 301 and 302 to the base unit 201 by the TDD-TDMA method conforming to the DECT standard. Base unit 201 has not only a function as a base unit of a general cordless telephone device but also a function as a home gateway. Therefore, base unit 201 is connected not only to fixed telephone line network FTN (general fixed telephone line network) but also to household appliance group APG including WiFi router 410 and various household appliances.

  The home appliance group APG includes a plurality of home appliances that are remotely operated according to a user's voice instruction. In the present embodiment, the home appliance group APG includes two lighting fixtures AP1, AP2, two air conditioners AP3, AP4, a television device AP5, a video device AP6, a refrigerator AP7, an electronic lens AP8, and a washing machine AP9. The household appliance group APG may include other household appliances. The principle of this embodiment is not limited at all by the household electric appliance group APG.

  The WiFi router 410 is communicably connected to the parent device 201 via Ethernet (registered trademark), and is communicably connected to the cloud server 420 via an Internet line. When one of the telephone slave units 301 and 302 is operating in the first operation mode (see FIG. 6), the call bit information and the call stream are transmitted from one of the telephone slave units 301 and 302 to the master unit 201. Sent. Master device 201 refers to the call bit information and determines to send the call stream to the call partner through the fixed telephone network. When one of the telephone slave units 301 and 302 is operating in the second operation mode (see FIG. 6), the instruction bit information and the instruction stream are transmitted from one of the telephone slave units 301 and 302 to the master unit 201. Sent. The base unit 201 refers to the instruction bit information and determines to send the instruction stream to the cloud server 420 through the WiFi router 410 and the Internet line.

  The cloud server 420 includes an authentication unit 421, a voice recognition unit 422, a dialogue unit 423, an operation command generation unit 424, a target device database 425, and an operation history database 426. The cloud server 420 stores information related to the cordless telephone device 101 in advance. When the cloud server 420 receives the instruction stream, the authentication unit 421 determines whether the instruction stream is transmitted from a legitimate cordless telephone device. Therefore, unauthorized remote operation with respect to the home appliance group APG is less likely to occur.

  Thereafter, the voice recognition unit 422 decodes the instruction stream and analyzes the voice instruction from the user. The target device database 425 stores in advance information about the lighting fixtures AP1 and AP2, air conditioning devices AP3 and AP4, the television device AP5, the video device AP6, the refrigerator AP7, the electronic lens AP8, and the washing machine AP9. The voice recognition unit 422 refers to the target device database 425 and finds the home appliance specified by the voice instruction. In addition, the voice recognition unit 422 finds out the operation content requested by the user from the voice instruction.

  When the user's voice instruction is unclear, the voice recognition unit 422 may activate the dialogue unit 423. For example, when the voice recognition unit 422 determines “startup” as the operation content, but the home appliance to be activated cannot be determined, the voice recognition unit 422 causes the dialogue unit to display “which home appliance to start. Message data representing the message “Do you want?” May be generated. The message data is transmitted to the telephone handset used by the user (one of the telephone handset units 301 and 302) through the Internet line, the WiFi router 410, and the base unit 201. As a result, the speaker 312 (see FIG. 5 or FIG. 7) outputs a message sound “Which home appliance will be activated?”. When the user thereafter inputs a voice instruction for designating the home appliance through the microphone 313, the voice recognition unit 422 can appropriately grasp the content of the remote operation requested by the user.

  The user may operate the telephone handsets 301 and 302 and request the cloud server 420 for interactive input. Also in this case, the voice recognition unit 422 can appropriately grasp the user's voice instruction in cooperation with the dialogue unit 423.

  The voice recognition unit 422 outputs the result of the voice recognition process described above to the operation command generation unit 424. The operation command generation unit 424 generates an operation command based on the result of the voice recognition process.

  The operation command generation unit 424 may refer to the operation history database 426 in order to generate an operation command. When the user operates the home appliances of the home appliance group APG, the content of the operation is delivered from the operated home appliances to the cloud server 420 through the parent device 201, the WiFi router 410, and the Internet line. As a result, the operation history database 426 can store the contents of the operation. The operation command generated by the operation command generation unit 424 may be output to the operation history database 426. As a result, the operation history database 426 can store the contents of the operation.

  When the result of the voice recognition processing indicates that “the user is requesting the operation of the air conditioner AP3 at the temperature setting of 28 ° C.”, the operation command generation unit 424 refers to the operation history database 426. It may be determined whether or not the air conditioner AP3 is in an activated state. When the air conditioner AP3 is in the activated state, the operation command generation unit 424 generates an operation command for setting the temperature to 28 ° C. When the air conditioner AP3 is not in the activated state, the operation command generating unit 424 generates an operation command for setting the air conditioner AP3 in the activated state and an operation command for setting the temperature to 28 ° C.

  The operation command is output from the operation command generation unit 424 to the WiFi router 410. Thereafter, the operation command is output from the WiFi router 410 to the home appliance specified by the user's voice instruction through the parent device 201. The household electric appliance that has received the operation command executes an operation designated by the user's voice instruction.

<Ninth Embodiment>
The operation mode of the telephone handset described in connection with the fifth to seventh embodiments can be switched by a simple operation on the telephone handset. Therefore, a person (for example, a young child) who does not have the ability to remotely control home appliances appropriately may operate the home appliances by mistake.

  Based on the principles of the above-described various embodiments, the designer can design a child device that is communicably connected to the parent device as a wearable terminal. In this case, the user can remove the wearable terminal from the body part. When the user leaves the wearable terminal removed from the body part, a third party may pick up the wearable terminal. When a third party operates the wearable terminal, the home appliance may perform an undesirable operation.

  FIG. 9 is a schematic block diagram of the wearable terminal 300D of the ninth embodiment. With reference to FIG. 9, wearable terminal 300D will be described. The code | symbol used in common between 7th Embodiment and 9th Embodiment means that the element to which the said common code | symbol was attached | subjected has the same function as 7th Embodiment. Therefore, description of 7th Embodiment is used for these elements.

  The designer may design the wearable terminal 300D so that the wearable terminal 300D is worn on the user's wrist. In this case, the designer may determine the design of the wearable terminal 300D so that the wearable terminal 300D looks like a wristwatch or a bangle. The designer may design the wearable terminal 300D so that the wearable terminal 300D is worn on the user's finger. In this case, the designer may determine the design of the wearable terminal 300D so that the wearable terminal 300D looks like a ring. The designer may design the wearable terminal 300D so that the wearable terminal 300D can be lowered from the user's neck. In this case, the designer may determine the design of the wearable terminal 300D so that the wearable terminal 300D looks like a pendant or a necklace. The principle of this embodiment is not limited to a specific wearing position or a specific design of the wearable terminal 300D.

  Similar to the seventh embodiment, the wearable terminal 300D includes an antenna unit 331, a power button 340B, and a power supply unit 350. The description of the seventh embodiment is incorporated in these elements.

  Wearable terminal 300D further includes a signal conversion unit 310D and an integrated circuit 320D. Similar to the seventh embodiment, the integrated circuit 320D performs signal processing for connection with the telephone of the other party, signal processing for switching the operation mode between the first operation mode and the second operation mode, It manages various signal processing such as bit information and signal processing for stream generation. The signal processing technique described in relation to the seventh embodiment is applied to the integrated circuit 320D.

  The signal converter 310D converts the signal output from the integrated circuit 320D into sound or an image. In addition, the signal conversion unit 310D converts user operations and voices into electrical signals.

  Similar to the seventh embodiment, the signal conversion unit 310 </ b> D includes a microphone 313 and a speaker 312. The description of the seventh embodiment is incorporated in these elements.

  The speaker 312 and the microphone 313 may be replaced by a device (for example, a headphone, a Bluetooth (registered trademark) hands-free microphone, or a Bluetooth (registered trademark) headset) different from the wearable terminal 300D. Therefore, the speaker 312 and the microphone 313 may be excluded from the signal conversion unit 310D.

  The signal conversion unit 310D further includes a touch panel 311D and a display 314. The user may operate the touch panel 311D and input the telephone number of the other party. The input telephone number is output to the integrated circuit 320D as an electrical signal. The integrated circuit 320D processes an electric signal representing a telephone number and transmits a radio wave representing the telephone number from the antenna unit 331 to the parent device.

  The display 314 displays various images according to the signal from the integrated circuit 320D. When the user operates the touch panel 311D and inputs the telephone number of the other party, the integrated circuit 320D may generate image data representing the input number. The image data is output from the integrated circuit 320D to the display 314. The display 314 displays numbers input by the user on the touch panel 311D according to the image data. As a result, the user can visually confirm whether or not the input telephone number is correct.

  Similar to the seventh embodiment, the integrated circuit 320 </ b> D includes an encoding unit 322, an I / O section 323, a timer 324, and a communication unit 332. The description of the seventh embodiment is incorporated in these elements.

  The integrated circuit 320D further includes a control unit 321D, a storage unit 325, and an authentication unit 326. The control unit 321D generally performs control related to data processing in the integrated circuit 320D. Therefore, the I / O section 323, the timer 324, the storage unit 325, the authentication unit 326, the encoding unit 322, and the communication unit 332 operate under the control of the control unit 321D.

  The control unit 321D may generate image data for requesting input of a password. The image data is output from the control unit 321D to the display 314 through the I / O section 323. As a result, the display 314 displays an image for requesting input of a password.

  The user operates the touch panel 311D according to the password request image on the display 314, and inputs the password. The authentication information indicating the input password is output from the touch panel 311D to the I / O section 323. The I / O section 323 outputs authentication information to the authentication unit 326 under the control of the control unit 321D.

  The storage unit 325 stores a password set in advance by the user. The authentication unit 326 that has received the authentication information reads the password from the storage unit 325. The authentication unit 326 then compares the authentication information with the read password.

  When the authentication information matches the read password, the authentication unit 326 notifies the control unit 321D that the authentication has been successfully completed. Thereafter, the control unit 321D may generate image data indicating that the authentication has been completed. The image data is output from the control unit 321D to the display 314 through the I / O section 323. As a result, the display 314 displays an image indicating that the authentication process has been completed successfully.

  When the authentication information does not match the read password, the authentication unit 326 notifies the control unit 321D that the authentication has failed. Thereafter, the control unit 321D may generate image data for prompting re-input of a password and / or interruption of authentication. The image data is output from the control unit 321D to the display 314 through the I / O section 323. As a result, the display 314 displays an image that prompts the user to re-enter the password and / or interrupt the authentication. The user operates the touch panel 311D according to the displayed image, and inputs the password again. Alternatively, the user operates touch panel 311D according to the displayed image, and requests wearable terminal 300D to interrupt the authentication process. The interruption processing request input through the touch panel 311D is output from the touch panel 311D to the control unit 321D through the I / O section 323. The control unit 321D that has received the request for the interruption process may cause the I / O section 323 to block the electrical signal from the microphone 313. As a result, remote operation by a person who does not know the password is prevented.

  When the authentication process is successfully completed, the authentication result may be held until the wearable terminal 300D is removed. Alternatively, the authentication process described above may be executed every time wearable terminal 300D is operated. Further alternatively, the above-described authentication process may be executed at another timing. The principle of the present embodiment is not limited to a specific timing when the authentication process is executed.

Wearable terminal 300S may be worn on the user's wrist. Alternatively, wearable terminal 300S may be worn on the user's finger. The principle of this embodiment is not limited to a specific mounting position of the wearable terminal 300S.

  When wearable terminal 300S is worn on the user's wrist, wearable terminal 300S may look like a wristwatch. When wearable terminal 300S is worn on the user's finger, wearable terminal 300S may look like a ring.

Unlike the ninth embodiment, the trigger signal for requesting generation of the instruction bit information and the instruction stream is generated not by the power button 340S but by the gesture detection circuit 360.

  The gesture detection circuit 360 includes a motion sensor 361 and a gesture determination unit 362. The motion sensor 361 detects the motion of the upper limb. The motion sensor 361 outputs motion data representing the motion of the upper limb. The motion sensor 361 may be an acceleration sensor. Alternatively, the motion sensor 361 may be an angular velocity sensor. The gesture determination unit 362 determines whether the user requests generation of instruction bit information and an instruction stream based on the exercise data. The gesture determination unit 362 that has determined that the user has requested generation of the instruction bit information and the instruction stream generates a trigger signal.

  FIG. 37 is a conceptual diagram of a three-dimensional coordinate system set in the upper limbs. A motion detection technique of the motion sensor 361 will be described with reference to FIGS.

  The detection unit 300 detects the movement of the upper limb portion in the first axis DVX direction. The coordinate axis extending straight from the vertically downward shoulder of the upper limb to the fingertip is referred to as a second axis PDX in the following description. A coordinate axis that is orthogonal to the second axis PDX and extends in the direction of movement of the user is referred to as a third axis FBX in the following description. The first axis DVX is orthogonal to the coordinate plane defined by the second axis PDX and the third axis FBX.

  The motion sensor 361 detects the motion of the upper limb in the extending direction of the first axis orthogonal to the coordinate plane defined by the second axis PDX and the third axis FBX. A detection axis of a sensor used as the motion sensor 361 may be orthogonal to a coordinate plane defined by the second axis PDX and the third axis FBX. In this case, the motion sensor 361 can accurately detect the motion (for example, acceleration and / or angular velocity) in the direction along the first axis DVX. Alternatively, the detection axis of the sensor used as the motion sensor 361 is inclined at an angle greater than 0 ° and less than 90 ° with respect to the coordinate plane defined by the second axis PDX and the third axis FBX. May be. In this case, the motion sensor 361 can detect not only the motion in the direction along the first axis DVX but also the motion in the direction along the coordinate plane defined by the second axis PDX and the third axis FBX. The gesture determination unit 362 performs a predetermined vector operation on the motion data output from the motion sensor 361, and is defined by the motion in the direction along the first axis DVX, the second axis PDX, and the third axis FBX. The movement in the direction along the coordinate plane may be evaluated individually. The principle of the present embodiment is not limited to a specific intersection angle of the detection axis of the sensor with respect to the coordinate plane defined by the second axis PDX and the third axis FBX.

  While the user is walking, the upper limb is frequently moved in the direction represented by the third axis FBX. When the user is trying to take an object that exists far away, the upper limb is extended, and thus the wearable terminal 300S is easily moved in the direction represented by the second axis PDX. When the user is trying to take an object that is present at a position close to the upper body, the upper limb is bent, so that the wearable terminal 300S is easily moved in the direction represented by the second axis PDX. These user actions occur frequently. However, the movement of the upper limb in the direction represented by the first axis DVX is rare compared to the movement in the direction represented by the third axis FBX and the second axis PDX. That is, the user rarely moves the upper limb at high speed and / or greatly in the direction represented by the first axis DVX.

  When the motion sensor 361 detects the motion of the upper limb (that is, the wearable terminal 300S) in the direction represented by the first axis DVX, the instruction bit information and the instruction stream are generated under the control of the control unit 321D. Remote operation on home appliances is unlikely to be initiated by the user's unconscious exercise. Therefore, the home appliance is difficult to operate unintentionally.

  FIG. 38 is a table showing an exemplary relationship between an operation requested by the user and an operation on wearable terminal 300S. With reference to FIGS. 36 to 38, an exemplary relationship between an operation requested by the user and an operation on the wearable terminal 300S will be described.

  When the user wants to remotely control the home appliance, the user may move the upper limb on which the wearable terminal 300S is worn in the direction represented by the first axis DVX. When the user requests a call through the wearable terminal 300S, the user may press the power button 340S. When the user wants to respond using the wearable terminal 300S when an incoming call is received by the smart phone, the user may touch the touch panel 311D.

  The principles of the various embodiments described above may be combined to meet the requirements for home appliance control.

  The principle of the above-described embodiment is suitably used for control of home appliances.
