Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.

With the continuous development of the AIot technology, more and more electric appliances are connected to the Internet. The user can control the intelligent device through voice commands, and the commands can be transmitted between the devices for indirect control. All the devices in the space can be controlled in a single sentence without configuring a remote controller for each device, so that the life and the work of a user are more rapid and convenient. For example, the user may wake up the sound box each time he shouts "love classmates", and perform voice control on the sound box after waking up, or control other devices through the sound box. For example, after the sound box is awakened, the sound box says "turn on the television" with the sound box, then the sound box can send an instruction to the television through the WIFI, and the television completes the power-on operation.

The inventor researches and discovers that in the scene, instruction transmission among all devices is through WIFI. However, due to factors such as poor router performance, excessive router connection devices, channel interference and the like, instructions sent by the devices are unstable, for example, a large time delay exists, so that the devices cannot respond in time, and user experience is affected.

In view of this, the present disclosure provides an apparatus communication method, which may transmit a control instruction between apparatuses in an ultrasonic communication manner, thereby reducing transmission delay caused by an obstructed WIFI network and improving a response speed of apparatus control.

Fig. 1 is a flow chart illustrating a method of device communication in accordance with an example embodiment. As shown in fig. 1, the device communication method may be applied to a first device, which may be any type of electronic device, such as a smart home device including a sound box, a television, an air conditioner, or other smart devices including a mobile phone, a computer, or the like, and the disclosure is not limited thereto.

Referring to fig. 1, the device communication method may include the steps of:

in step 11, a voice control command of a user is received and analyzed to obtain control information, where the control information includes a control action and a control object.

In step 12, if the control object in the control information is the second device, it is determined whether the first device and the second device are in the same space.

In step 13, if the first device and the second device are in the same space, an ultrasonic control command is generated based on the control information, and the ultrasonic control command is played in the same space by means of ultrasonic waves.

It should be understood that WIFI is unobstructed, and the transmission of information between devices may only require tens of milliseconds, but obstructed, and the transmission delay between devices may reach several seconds, and the response is unstable and may be slow. And the propagation speed of sound stabilizes to around 340 m/s. Taking 10 meters as an example, the transmission time of the ultrasonic wave is less than 30 milliseconds, so that the control instruction is stably and quickly transmitted.

Therefore, in the embodiment of the present disclosure, the ultrasonic wave playing control instruction is adopted in the same space, and compared with a mode in which the WIFI network is used to send the control instruction in the related art, transmission delay caused by unsmooth WIFI network can be reduced, and the mode of playing the control instruction through the ultrasonic wave has no influence of factors such as channel interference, so that the condition that the control instruction is sent unstably is avoided, and the device can respond to the instruction of the user at a higher speed.

In order to make those skilled in the art understand the device communication method provided by the embodiments of the present disclosure, the following detailed description illustrates the above steps.

For example, the voice control instructions may include device wake-up instructions for the first device and/or specific control instructions for the first device or other devices. For example, the user may first issue a device wake-up command, the first device responds, and then the user gives a specific device control command to the first device. Or, the user may give the device wake-up instruction and the specific control instruction to the first device at the same time. For example, the voice control command is: the young lovely classmates please turn on the television. Wherein, the "love classmates" is a wake-up instruction, and the control information obtained by analysis includes: the control action is on and the control object is a television.

For example, the first device may be located in the same local area network as the plurality of second devices and communicatively connected to each other. If the control information analyzed by the first device indicates to control the second device, the first device may send the control information to the second device, so as to control the second device to perform a corresponding control action. In the related art, the control information is transmitted in a WIFI manner, and a large transmission delay may be caused due to an obstructed WIFI network, so that the response speed of the second device is low, and user experience is affected. In the embodiment of the disclosure, it may be determined whether the first device and the second device are in the same space, and if the first device and the second device are in the same space, the control information may be transmitted in an ultrasonic manner, so as to reduce transmission delay and improve device response speed.

In a possible manner, determining whether the first device and the second device are in the same space includes: determining whether the first equipment and the second equipment are in the same space or not according to the identification of the second equipment and a pre-stored same space identification list; and the same space identification list comprises the identification of the equipment in the same space with the first equipment.

That is to say, the first device may add and store the identifier of the device in the same space as the first device in the same space identifier list in advance, so that the subsequent first device may determine whether another device (for example, the second device) is in the same space as the first device through the same space identifier list.

In a possible manner, the same spatial identifier list may be obtained and stored in any one of the following manners:

playing a target ultrasonic signal to other equipment around the first equipment, and adding the identification of the other equipment into the same space identification list if receiving a feedback signal which is returned by the other equipment and aims at the target ultrasonic signal; and acquiring configuration information input by a user, wherein the configuration information comprises an identifier of a target device in the same space with the first device, and adding the identifier of the target device into the same space identifier list.

That is, the space can be divided in two ways, namely, automatic sensing and user configuration, so as to obtain the same space identifier list.

For example, user configuration requires the user to select the space in which the device is located each time the network is configured. For example, a living room is selected for the television and the sound box, and a master bedroom is selected for the air conditioner and the smart alarm, then the television and the sound box know that they are in a subspace, and the air conditioner and the alarm know that they are in a subspace. It should be understood that, in the embodiments of the present disclosure, the division of the same space may be performed according to a large-area completely-blocked object, such as a wall, a wardrobe in contact with a ceiling, goods stacked on the ceiling, and the like, and the embodiments of the present disclosure are not limited thereto. In specific implementation, a user can select different modes to divide the space according to actual conditions.

Illustratively, the automatic sensing is performed by ultrasonic waves between devices. For example, the automatic sensing may be that the first device plays an ultrasonic signal to peripheral devices, where the first device and the plurality of second devices are respectively in the same local area network and may be in communication connection with each other. And if a feedback signal of the second equipment for the target ultrasonic signal is received, the second equipment is in the same space with the first equipment, and the second equipment identifier is added into the same space identifier list. For example, the ultrasonic information played by the sound box can only be received by the television, and the television knows that the sound box and the television are in the same subspace because the wall obstructs the air conditioner and the alarm clock cannot receive the ultrasonic information. And each device senses in sequence, and finally, the space where all the devices are located can be divided. Each device stores the IP addresses or other identification IDs of other devices in the same space identification list. Thus, the same spatial identification list may include identifications of other respective devices that are within the same space as the first device. The identifier may be a name of the device or a number customized by the user, which is not limited in this disclosure.

The first device may then query the identity of the second device in the same spatial identity list of the first device to determine whether the second device is in the same space as the first device. If the identifier of the second device is inquired in the same space identifier list of the first device, it is determined that the second device and the first device are in the same space, so that the ultrasonic control instruction can be played in the same space in an ultrasonic mode to control the second device. Otherwise, if the identifier of the second device is not queried in the same space identifier list of the first device, it is determined that the second device and the first device are not in the same space.

For example, if the first device and the second device are in the same space, the first device may encode the IP address or other identification ID information of the second device into ultrasonic information by Frequency Shift Keying (FSK) technology, and then encode the control command into ultrasonic information and append the ultrasonic information to the IP address to obtain a complete encoded ultrasonic signal. Then, the ultrasonic signal is played in the space through the voice playing component of the first device, and a microphone of other devices including the second device in the same space with the first device can pick up and analyze sound fields in the space. If the device receiving the ultrasonic signal recognizes that the identifier (such as an IP address or other identification ID information) in the ultrasonic signal matches its own identifier, the parsed control information is executed.

In other possible manners, if the first device and the second device are not in the same space, a WIFI control instruction may be generated based on the control information, and the WIFI control instruction may be sent to the second device.

Therefore, ultrasonic communication can be adopted in the same space, and WIFI communication can be adopted in the cross-space mode, so that the communication requirements under different scenes can be met while the transmission delay is reduced.

In other possible manners, if the first device and the second device are not in the same space, a WIFI control instruction may also be generated based on the control information, and the WIFI control instruction is sent to the second device, and the following steps are executed at the same time: and generating an ultrasonic control instruction based on the control information, and playing the ultrasonic control instruction in the same space in an ultrasonic mode.

That is to say, under the condition of crossing the space, namely first equipment and second equipment are not in same space, then first equipment also sends control command through WIFI through ultrasonic wave broadcast control command simultaneously, so the second equipment will receive two control commands that are sent through ultrasonic wave and WIFI. In this case, the second device may respond upon receipt of a first control instruction, and discard the control instruction when a second identical control instruction arrives. Therefore, repeated response can be avoided, and unnecessary control operation can be reduced.

In other possible manners, if the first device and the second device are not in the same space, a third device may be determined, where the third device is in the same space as the first device and can perform ultrasonic communication with the second device, and then the ultrasonic control command is played in the same space in an ultrasonic manner, so that the third device plays the ultrasonic control command in a space around the third device after receiving and determining the control command for controlling the second device.

That is, the third device may be selected as the relay communication of the ultrasonic wave in the embodiment of the present disclosure.

For example, the number of the third devices may be one or more, which is not limited in this disclosure, and in a specific implementation, a corresponding number of the third devices may be set as the relay station according to an actual situation.

In a possible approach, determining the third device may be: acquiring equipment configuration information input by a user, wherein the configuration information comprises equipment for playing an ultrasonic control instruction played by first equipment; determining a third device according to the device configuration information; or playing the ultrasonic signal to each device which is in the same space with the first device and can perform ultrasonic communication with the second device, so that each device plays the received ultrasonic information in the surrounding space, receiving a feedback signal which is returned by each device and is aimed at the ultrasonic signal by the second device, and determining the device with the maximum feedback signal strength as the third device.

That is, the third device may be determined in a user-configured and auto-aware manner.

For example, the user configuration means that a device previously designated by the user may be determined as the third device.

For example, for the automatic sensing mode, on the basis of dividing the space, the detection sensing may be performed by using ultrasonic waves at intervals, that is, the first device plays an ultrasonic wave signal in the space where the first device is located, then a feedback signal for the ultrasonic wave signal played by the first device returned by each device in the same space is received, and finally the device with the highest feedback signal strength is determined as the third device. It should be understood that, when the ultrasonic wave propagates in the air, the ultrasonic intensity gradually decreases with the increase of the propagation distance, and the energy is gradually consumed, so that the intensity of the feedback signal is maximum, which indicates that the transmission distance of the device is minimum, the time required for transmission is shortest, and the transmission effect is better, so in the embodiment of the present disclosure, the device with the maximum intensity of the feedback signal may be determined as the third device.

It should be understood that if the second device is not in the same space as the first device, but the space in which the first device is located and the space in which the second device is located are communicable, the first device and the second device may be considered to be in a temporarily communicable general subspace when the space in which the first device is located and the space in which the second device is located are communicated. For example, in a home scenario, when all doors are closed, the ultrasonic signals between different spaces are not reachable. Many times the door is open as shown in figure 2. When the door is closed, the equipment A and the equipment B are in a space, and the equipment C and the equipment D are in a space. However, when the door is opened, the ultrasonic waves emitted by the device B can reach the device C and the device D at a high probability, and the device B, the device C and the device D can be considered to be in a general subspace.

In this case, since the communication distance exceeds the line of sight, the signal is attenuated quickly, and the communication quality cannot be ensured. In order to solve the problem and improve the communication quality, a third device may be determined as a relay station between the first device and the second device, the third device receives and recognizes the ultrasonic control command played by the first device, and when the third device recognizes that the ultrasonic control command is used for controlling the command of the second device, the third device plays the ultrasonic control command in the surrounding space of the third device. For example, referring to fig. 2, if the device a is awakened and the device C or the device D is to be controlled, the device a may play the ultrasonic control command in the surrounding space. When the device B receives the ultrasonic control command and recognizes that the device C or the device D is to be controlled, the ultrasonic control command is played in the surrounding space of the device B. And because the room where the device B is located and the doors between the room where the device C and the device D are located are in an open state, the ultrasonic control instruction played by the device B may reach the device C or the device D.

Therefore, in the communication process of the first equipment and the second equipment, the third equipment can be used for carrying out ultrasonic relay communication, so that better communication quality is ensured, and the transmission delay of control instructions between the equipment is reduced.

Fig. 3 is a flow chart illustrating a method of device communication according to another exemplary embodiment. As shown in fig. 3, the device communication method may be applied to a second device, where the second device may be any type of electronic device, such as a smart home device including a sound box, a television, an air conditioner, or other smart devices including a mobile phone, a computer, and the like, and the disclosure is not limited thereto.

Referring to fig. 3, the device communication method includes the steps of:

in step 31, an ultrasonic control command played by the first device is received.

In step 32, the ultrasonic control command is analyzed to obtain control information including a control action and a control target.

In step 33, it is determined whether the current device is a control target according to the control information.

In step 34, if the current device is the control object, the control action indicated by the control information is executed, and if the current device is not the control object, the received ultrasonic control command is played.

For example, it has been described above that the first device may be respectively located in the same local area network as the plurality of second devices and communicatively connected to each other. Therefore, after the first device plays the ultrasonic control command in the space, a plurality of second devices can receive the ultrasonic control command. After receiving the ultrasonic control instruction, a certain second device firstly analyzes the ultrasonic control instruction to obtain control information, and then confirms whether the second device is a control object corresponding to the control information according to the control information. If so, the second device executes the control action indicated by the control information, otherwise, the second device can play the received ultrasonic control instruction so as to transmit the corresponding control information to other devices in an ultrasonic mode.

It should be understood that, the content of the above description about the first device may be referred to for the execution process of the second device after receiving the ultrasonic control instruction, and details are not described here again.

Based on the same concept, the present disclosure also provides a device communication method, which may be applied to a second device, where the second device may be any type of electronic device, such as smart home devices including a sound box, a television, an air conditioner, and the like, or other smart devices including a mobile phone, a computer, and the like, and the present disclosure is not limited thereto.

The device communication method comprises the following steps:

if the WIFI control instruction is received after the ultrasonic control instruction played by the first device is received, the WIFI control instruction is discarded.

If the ultrasonic control instruction is received after the WIFI control instruction sent by the first device is received, discarding the ultrasonic control instruction;

the ultrasonic control command and the WIFI control command contain the same control information, and the control information comprises a control action and a control object.

It should be understood that, in the case of crossing the space, that is, the first device and the second device are not in the same space, the first device also sends the control instruction through the WIFI while playing the control instruction through the ultrasonic wave, so the second device will receive the two control instructions sent through the ultrasonic wave and the WIFI. In this case, the second device may respond upon receipt of a first control instruction, and discard the control instruction when a second identical control instruction arrives. Therefore, repeated response can be avoided, and unnecessary control operation can be reduced.

The following describes a communication procedure between the first device, the second device and the third device by means of another exemplary embodiment. As shown in fig. 4, the device communication method may include the steps of:

and step 41, the first device receives and analyzes the voice control instruction of the user to obtain control information, and determines the voice control instruction to be used for controlling the second device according to the control information. It should be understood that the control information includes a control action and a control object, so that the first device can determine whether the voice control instruction is used to control the second device by whether the control object included in the control information is the second device.

In step 42, the first device queries the identifier of the second device in the same spatial identifier list device list, if so, step 43 is executed, otherwise, step 44 is executed.

And 43, the first equipment plays the ultrasonic control command in the same space in an ultrasonic mode.

Step 44, the first device determines the third device by means of ultrasonic automatic sensing.

And step 45, the third equipment identifies and analyzes the received ultrasonic control command, and plays the ultrasonic control command in the surrounding space after determining that the ultrasonic control command is used for controlling the second equipment.

And step 46, the second equipment responds to the received ultrasonic control command and controls the equipment based on the ultrasonic control command.

Through the mode, the cross-space WIFI is used for sending the control command, the control command is transmitted in the same space by an ultrasonic mode, the transmission time delay caused by the fact that a WIFI network is not smooth can be reduced, the influence of factors such as channel interference does not exist in the ultrasonic mode, the condition that the control command is sent unstably is avoided, and the device can respond to the command of the user at a higher speed.
