The WIFI network remote control requires the user to manually perform the networking operation, and the remote controller and the controlled device are connected under the same WIFI network. At the same time, the security is not high, and it is easy for the third party to invade the WIFI network to control the controlled device. Bluetooth matching remote control and infrared matching remote control are point-to-point communication, which has high security, but also requires manual user to perform matching operation, and Bluetooth signal and infrared signal are easily interfered or interfere with other electromagnetic signals, affecting the stability of remote control, and infrared The matching remote control mode also needs to align the remote controller with the controlled device, which is inconvenient to operate.
综上所述，现有的遥控方式的遥控性能较差，用户体验不佳。In summary, the remote control performance of the existing remote control mode is poor, and the user experience is not good.

The terminal device may be a mobile terminal such as a mobile phone or a tablet, and the smart home device may be a smart speaker, a smart refrigerator, a smart air conditioner, a smart TV, and the like. The following is a detailed description of the application to the smart speaker.
参照图1，提出本发明的语音遥控方法第一实施例，所述方法包括以下步骤：Referring to Figure 1, a first embodiment of a voice remote control method of the present invention is presented. The method includes the following steps:
S11、接收语音指令。S11. Receive a voice instruction.
可选地，智能音箱包括声音采集单元，通过声音采集单元接收语音指令。声音采集单元可以是单个麦克风，也可以是由至少两个麦克风组成的麦克风阵列。智能音箱通过单个麦克风或麦克风阵列采集语音信号（语音指令），并对语音信号进行滤波放大、降噪、模数转换等一系列处理，将语音信号从模拟信号形式后转换为数字信号形式。Optionally, the smart speaker includes a sound collection unit that receives voice commands through the sound collection unit. The sound collection unit may be a single microphone or a microphone array composed of at least two microphones. The intelligent speaker collects voice signals (voice commands) through a single microphone or microphone array, and performs a series of processing such as filtering amplification, noise reduction, analog-to-digital conversion on the voice signals, and converts the voice signals from the analog signal form to the digital signal form.
可选地，智能音箱包括无线通信单元，通过无线通信单元接收外部设备发送的语音指令。无线通信单元可以为蓝牙单元、WIFI单元或蜂窝网络单元等任意一种，智能音箱通过蓝牙单元、WIFI单元或蜂窝网络单元与手机、平板等移动终端建立无线连接，接收移动终端发送的语音指令，从而使得用户可以远距离甚至在外面也可以借助移动终端控制家电设备。Optionally, the smart speaker includes a wireless communication unit that receives a voice command sent by the external device through the wireless communication unit. The wireless communication unit may be any one of a Bluetooth unit, a WIFI unit or a cellular network unit. The smart speaker establishes a wireless connection with a mobile terminal such as a mobile phone or a tablet through a Bluetooth unit, a WIFI unit or a cellular network unit, and receives a voice command sent by the mobile terminal. Thereby, the user can control the household electrical appliance by means of the mobile terminal even at a distance or even outside.
进一步地，为了防止误操作，还可以设置唤醒关键词，只有在语音控制时加入唤醒关键词时，才能对家电设备进行控制。具体的，智能音箱接收语音信息，判断语音信息中是否包含唤醒关键词；当语音信息中包含唤醒关键词时，智能音箱则确定该语音信息为语音指令；当语音信箱中不包含唤醒关键词时，智能音箱则确定该语音信息不是语音指令，丢弃该语音信息。Further, in order to prevent erroneous operation, a wake-up keyword can also be set, and the home appliance can be controlled only when a wake-up keyword is added during voice control. Specifically, the smart speaker receives the voice information, and determines whether the voice message includes the wake-up keyword; when the voice message includes the wake-up keyword, the smart speaker determines that the voice message is a voice command; when the voice mailbox does not include the wake-up keyword The smart speaker determines that the voice message is not a voice command and discards the voice message.
智能音箱可以对每次采集的语音信息都进行唤醒关键词的检测，即用户每次进行语音控制时都需要说出唤醒关键词。也可以在一定时间内进行一次唤醒关键词的检测，即当智能音箱被唤醒后，在一定时间内用户再次进行语音控制时无需再说出唤醒关键词，只当超过预设时间没有接收到下一条语音指令时，智能音箱才再次进入休眠状态，需要用户再次通过唤醒关键词唤醒，从而提高语音控制的便捷性。The smart speaker can detect the wake-up keyword for each collected voice information, that is, the user needs to speak the wake-up keyword every time the user performs voice control. It is also possible to perform a wake-up keyword detection within a certain period of time, that is, when the smart speaker is woken up, the user does not need to say the wake-up keyword again when the user performs voice control again within a certain period of time, and the next one is not received when the preset time is exceeded. When the voice command is issued, the smart speaker enters the sleep state again, and the user needs to wake up again by waking up the keyword, thereby improving the convenience of voice control.
S12、对语音指令进行语音识别，获取控制命令。S12. Perform voice recognition on the voice command to obtain a control command.
智能音箱对语音指令进行语音识别，将语音指令转换为文本信息，从而获取该语音指令中包含的控制命令。The intelligent speaker performs voice recognition on the voice command, converts the voice command into text information, and acquires the control command included in the voice command.
智能音箱可以在本地对语音指令进行语音识别，也可以将语音指令发送给云端的服务器，由服务器对语音指令进行语音识别，接收服务器返回的文本信息，从而获取控制命令。The smart speaker can perform voice recognition on the voice command locally, or send the voice command to the server in the cloud, and the server performs voice recognition on the voice command, and receives the text information returned by the server, thereby acquiring the control command.
S13、对控制命令进行超声波编码，生成超声波遥控信号。S13: Ultrasonic coding the control command to generate an ultrasonic remote control signal.
本发明实施例中，智能音箱可以只遥控一个家电设备，也可以遥控至少两个家电设备。当遥控至少两个家电设备时，控制命令则需要包括控制对象和控制指令，其中：控制对象即需要控制的家电设备，如电视机、空调、风扇、冰箱等；控制指令即需要控制对象执行的动作，如开启、关闭、升高/降低音量/温度、切换到上一个/下一个等等。In the embodiment of the invention, the smart speaker can remotely control only one household electrical appliance, and can also remotely control at least two household electrical appliances. When remotely controlling at least two home appliances, the control command needs to include a control object and a control command, wherein: the control object is a home appliance that needs to be controlled, such as a television, an air conditioner, a fan, a refrigerator, etc.; the control command needs to control the execution of the object. Actions such as turning on, off, raising/lowering the volume/temperature, switching to the previous/next, and so on.
例如：控制命令为“开启空调”，则控制对象为“空调”，控制指令为“开启”；控制命令为“调高电视音量”，则控制对象为“电视”，控制指令为“调高音量”。For example, if the control command is “turn on the air conditioner”, the control object is “air conditioner”, the control command is “on”; if the control command is “teleten the TV volume”, the control object is “television”, and the control command is “turn up the volume”. ".
可选地，可以为不同的受控设备（如家电设备）分配不同的超声波频段，智能音箱向不同的家电设备发送不同频段的超声波，而各个家电设备也只接收特定频段的超声波。Optionally, different ultrasonic frequency bands may be allocated to different controlled devices (such as home electric appliances), and the smart speakers send ultrasonic waves of different frequency bands to different home electric devices, and each household electrical device only receives ultrasonic waves of a specific frequency band.
具体的，智能音箱根据控制对象确定与该控制对象相对应的超声波频段，然后在对应的超声波频段内对控制指令进行超声波编码，生成超声波遥控信号。后续只有该控制命令指定的控制对象才能接收到该超声波遥控信号，并对该超声波遥控信号进行解码后获取对应的控制指令，并执行该控制指令。Specifically, the smart speaker determines an ultrasonic frequency band corresponding to the control object according to the control object, and then ultrasonically encodes the control command in the corresponding ultrasonic frequency band to generate an ultrasonic remote control signal. Only the control object specified by the control command can receive the ultrasonic remote control signal, and decode the ultrasonic remote control signal to obtain a corresponding control command, and execute the control command.
可选地，智能音箱可以为不同的家电设备分配不同的识别码，而家电设备通过识别码来识别接收到的超声波是否为发给自己的超声波遥控信号。Optionally, the smart speaker can assign different identification codes to different home appliances, and the home appliance uses the identification code to identify whether the received ultrasonic wave is an ultrasonic remote control signal sent to itself.
具体的，智能音箱根据控制对象确定与该控制对象对应的识别码，并在预设的超声波频段内对控制指令进行超声波编码，然后将识别码添加到超声波编码的头部，当然也可以添加到尾部等其它部位，生成超声波遥控信号。后续该控制命令指定的控制对象接收到该超声波遥控信号时，通过识别码识别出该超声波遥控信号是发送给自己的，然后对该超声波遥控信号进行解码后获取控制指令，并执行该控制指令。Specifically, the smart speaker determines an identification code corresponding to the control object according to the control object, and ultrasonically encodes the control command in a preset ultrasonic frequency band, and then adds the identification code to the head of the ultrasonic code, which may of course be added to An ultrasonic remote control signal is generated at other parts such as the tail. When the control object specified by the control command receives the ultrasonic remote control signal, the identification signal identifies that the ultrasonic remote control signal is transmitted to itself, and then decodes the ultrasonic remote control signal to obtain a control command, and executes the control command.
S14、向外发射超声波遥控信号。S14. Transmitting an ultrasonic remote control signal.
智能音箱生成超声波遥控信号后，通过超声波发射器向外发射超声波遥控信号。受控设备（如家电设备）接收到超声波遥控信号后，对该超声波遥控信号进行解析，获取控制指令，并执行该控制指令。After the intelligent speaker generates the ultrasonic remote control signal, the ultrasonic remote control signal is transmitted through the ultrasonic transmitter. After receiving the ultrasonic remote control signal, the controlled device (such as the household electrical appliance) parses the ultrasonic remote control signal, acquires a control command, and executes the control command.
进一步地，如图2所示，在本发明的语音遥控方法第二实施例中，步骤S15之后还包括以下步骤：Further, as shown in FIG. 2, in the second embodiment of the voice remote control method of the present invention, after step S15, the following steps are further included:
S15、接收超声波反馈信号。S15. Receive an ultrasonic feedback signal.
本实施例中，受控设备执行完控制指令后，还将执行结果以超声波反馈信号的形式发送给智能音箱，智能音箱通过超声波接收器接收受控设备发送的超声波反馈信号。In this embodiment, after the controlled device executes the control instruction, the execution result is sent to the smart speaker in the form of an ultrasonic feedback signal, and the smart speaker receives the ultrasonic feedback signal sent by the controlled device through the ultrasonic receiver.
S16、对超声波反馈信号进行超声波解码，获取反馈信息。S16. Perform ultrasonic decoding on the ultrasonic feedback signal to obtain feedback information.
智能音箱对超声波反馈信号进行超声波解码，获取受控设备反馈的执行结果，即反馈信息。所述反馈信息如：执行成功、执行失败、空调启动成功、电视音量调节成功、风扇关闭失败等。The intelligent speaker ultrasonically decodes the ultrasonic feedback signal to obtain the execution result of the feedback of the controlled device, that is, the feedback information. The feedback information is as follows: execution success, execution failure, air conditioner startup success, TV volume adjustment success, fan shutdown failure, and the like.
S17、输出反馈信息。S17. Output feedback information.
智能音箱可以通过发声装置（如喇叭）输出反馈信息，还也可以通过显示屏显示反馈信息，或者通过灯光亮灭、闪烁的方式示意反馈信息。The smart speaker can output feedback information through a sounding device (such as a speaker), or display feedback information through the display screen, or indicate the feedback information by means of the light being turned on and off.
智能音箱可以只在遥控失败时才输出反馈信息提醒用户，也可以在无论遥控失败还是遥控成功时都输出反馈信息提醒用户。The smart speaker can only output feedback information to remind the user when the remote control fails, and can also output feedback information to remind the user whether the remote control fails or the remote control succeeds.
从而，通过输出反馈信息，使得用户可以及时的知道遥控结果，提升了用户体验。Therefore, by outputting the feedback information, the user can know the remote control result in time and improve the user experience.
本发明实施例的语音遥控方法，通过将语音指令转换为超声波遥控信号，并向控受控设备发射超声波遥控信号，实现了通过超声波进行语音遥控，解放了用户的双手。并且，无需用户手动进行组网操作或匹配操作，提高了操作的便捷性；超声波通信属于点对点通信，安全性较高；超声波与其它电磁信号的重合率较低，不容易被其它电磁信号干扰，故遥控稳定性较高；超声波在空间中发散传播，无需对准受控设备，既提高了操作的便捷性，又可以方便的遥控多个受控设备。从而提高了遥控操作的安全性、稳定性和便捷性，极大的提高了遥控性能，提升了用户体验。The voice remote control method of the embodiment of the present invention liberates the hands of the user by converting the voice command into an ultrasonic remote control signal and transmitting the ultrasonic remote control signal to the controlled controlled device, thereby realizing the voice remote control by the ultrasonic wave. Moreover, the user does not need to manually perform the networking operation or the matching operation, thereby improving the convenience of operation; the ultrasonic communication belongs to the point-to-point communication, and the security is high; the coincidence rate of the ultrasonic wave with other electromagnetic signals is low, and is not easily interfered by other electromagnetic signals. Therefore, the remote control stability is high; the ultrasonic wave spreads and spreads in the space, and it is not necessary to align the controlled equipment, thereby improving the convenience of operation and conveniently controlling a plurality of controlled devices.
