[0115] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0116] Reference Figure 1 , shows a flowchart of a first embodiment of an interaction method of a smart device of the present application, wherein the smart device is provided with a first LoRa ranging device, and the interaction object is provided with a second LoRa ranging device, and the method may specifically include the following steps:

[0117] Step 101, the smart device communicates with the second LoRa ranging device of the interactive object through the first LoRa ranging device, and determines the interactive object information according to the communication information, wherein the interactive object information includes ranging information for the interactive object;

[0118] In the embodiment of the present application, the smart device may be a device having the function of interacting with the user, such as a smart speaker and a smart phone. The interactive object may be a person or a pet. The interactive object may wear one second LoRa ranging device or multiple second LoRa ranging devices to enhance the accuracy of ranging information.

[0119] The Internet of Things technology is the third information technology revolution after computers and the Internet. It has the advantages of real-time and interactivity, and has been widely used in many fields such as urban management, digital home, positioning navigation, logistics management, security systems, etc. Among them, LoRa is an ultra-long-distance transmission solution based on spread spectrum technology in the Internet of Things, with the characteristics of long transmission distance, low power consumption, multiple nodes and low cost.

[0120] In an embodiment of the present application, the smart device may be provided with a first LoRa ranging device, and the interactive object may be provided with a second LoRa ranging device. The first LoRa ranging device and the second LoRa ranging device may communicate with each other. The smart device may determine the interactive object information based on the communication information between the two. The interactive object information may include ranging information for the interactive object.

[0121] The ranging information may include distance and signal characteristics (such as signal strength), and the ranging information may also include information calculated based on the distance or signal characteristics, for example, "long distance", "short distance", "signal strength: strong", "signal strength: medium", "signal strength: weak".

[0122] In an embodiment of the present application, the interactive object information may further include identification information of the interactive object. The identification information of the interactive object is information used to identify the identity of the interactive object, and may include the name, age, gender, etc. of the interactive object.

[0123] In the embodiment of the present application, the smart device receives the first wireless frame sent by the second LoRa ranging device of the interactive object through the first LoRa ranging device, and the smart device can calculate the distance between the smart device and the interactive object according to the flight time of the first wireless frame, and determine the RSSI (Received Signal Strength Indication) of the first wireless frame. The first wireless frame may include identification information of the interactive object, and the smart device may extract the identification information therein after receiving the first wireless frame.

[0124] In an example of an embodiment of the present application, the smart device sends a second wireless frame to the second LoRa ranging device of the interactive object through the first LoRa ranging device, and the second LoRa ranging device of the interactive object is used to send the first wireless frame after receiving the second wireless frame.

[0125] In this example, the second wireless frame may be a ranging request wireless frame, and the first wireless frame may be a ranging response wireless frame. The first LoRa ranging device may broadcast the second wireless frame, and after receiving the second wireless frame, the second LoRa ranging device may send (may be broadcast or unicast) the first wireless frame to the first LoRa ranging device.

[0126] In an embodiment of the present application, the smart device can communicate with a control device, and the control device can be deployed on a cloud server or on the smart device. The control device can send a search instruction to the smart device, and when the smart device receives the search instruction, the smart device transmits a second wireless frame through the first LoRa ranging device to search for surrounding interactive objects.

[0127] In the embodiment of the present application, the smart device may also be provided with a biometric information sensor, such as an infrared sensor. When the biometric information sensor detects biometric information of an interactive object around, the smart device transmits a second wireless frame through the first LoRa ranging device to search for the interactive object around.

[0128] In another example of the present application, the interactive object may be provided with a motion sensor, and the motion sensor may detect whether the interactive object is moving. When the interactive object is detected to be moving, the second LoRa ranging device sends the first wireless frame to the first LoRa ranging device. When the interactive object does not move, the second LoRa ranging device does not send the first wireless frame to save power.

[0129] Step 102: the smart device sends a voice message according to the interaction object information.

[0130] In the embodiment of the present application, the smart device can actively send out voice information based on the interaction object information, thereby actively guiding the interaction object to establish voice interaction with the smart device.

[0131] Specifically, it can be determined based on the distance measurement information whether an interactive object is within a preset distance range relative to the smart device. If an interactive object is within the preset distance range, the smart device can send a voice message.

[0132] Furthermore, if the interaction object information also includes identification information of the interaction object, the smart device can perform voice communication based on the identification information of the interaction object. For example, if the name of the interaction object is "Xiao Ming" based on the identification information of the interaction object, the smart device can send a voice message of "Hello Xiao Ming" to greet the interaction object.

[0133] If the interaction object information does not include identification information of the interaction object, the smart device may send a voice message to inquire about the identity, such as “Who are you?”.

[0134] The method of the embodiment of the present application can realize active voice interaction with children. For example, when the smart device determines that a child is approaching based on the interaction object information, the smart device can actively send a voice message to greet the child.

[0135] The method of the embodiment of the present application can also realize the function of child care. For example, when the smart device determines that a child is walking farther and farther away and the distance exceeds the preset safety distance threshold based on the information of the interaction object, the smart device can actively send a voice message to call the child back or call the parents, thereby realizing the function of child care.

[0136] The method of the embodiment of the present application can also realize the pet training function. For example, the smart device determines that there is a pet dog nearby based on the interactive object information, and the smart device can issue a voice message of the command. The motion detection module set on the pet dog can detect the motion information of the pet dog, and the second LoRa ranging device set on the pet dog sends the motion information to the first LoRa ranging device. Therefore, the smart device can judge whether the pet dog moves according to the command based on the motion information, and emit a specific sound to reward or punish the pet according to the judgment result, thereby realizing the pet training function.

[0137] In an embodiment of the present application, the second LoRa ranging device may be provided with a reminder device, which may remind the interactive object by emitting light, flashing, vibrating, etc., to inform the interactive object that voice interaction is being performed with the smart device.

[0138] In an embodiment of the present application, step 102 may specifically include the following sub-steps:

[0139] Sub-step S11, the smart device acquires reference feature information;

[0140] Specifically, the reference feature information may include: a reference distance, a reference signal strength, a reference volume, and a reference voice content. The reference feature information may be stored in a preset feature database.

[0141] The interactive object has corresponding reference feature information. If the interactive object information includes the identification information of the interactive object, the smart device can obtain the corresponding reference feature information from the feature database according to the identification information of the interactive object. If the interactive object information does not include the identification information of the interactive object, the smart device can obtain general reference feature information.

[0142] Sub-step S12, the smart device compares the reference feature information with the distance measurement information;

[0143] The smart device can compare the distance in the current ranging information with the reference distance, and / or compare the signal strength in the current ranging information with the reference signal strength; the smart device determines whether the preset requirements are met based on the comparison result. For example, if the distance of the current ranging information is greater than or equal to the reference distance, and the signal strength of the current ranging information is greater than or equal to the reference signal strength, the smart device determines that the preset requirements are met. For another example, as long as the distance of the current ranging information is greater than or equal to the reference distance, the smart device determines that the preset requirements are met. For another example, as long as the signal strength of the current ranging information is greater than or equal to the reference signal strength, the smart device determines that the preset requirements are met. Of course, the technology in the field can also set other preset requirements according to actual needs, and the embodiments of the present application are not limited to this.

[0144] Sub-step S13, if the comparison result meets the preset requirement, the smart device sends a voice message;

[0145] In an embodiment of the present application, the smart device can send voice information based on the reference feature information.

[0146] Furthermore, the smart device can adjust the voice volume and voice content according to parameters such as reference feature information, current distance measurement information, identification information of the interactive object, etc., so as to flexibly and appropriately send out voice information.

[0147] In the embodiment of the present application, it is also possible to further determine whether to send a voice message through voiceprint judgment processing. Specifically, the step of sending a voice message by a smart device may include: the smart device sends a first voice message; the smart device receives a second voice message of the interactive object; the smart device determines whether the second voice message matches the identification information of the interactive object through the voiceprint; if the voiceprint matches successfully, the smart device initiates a voice interaction process. The interactive object is further determined through voiceprint matching.

[0148] The first voice message may be a greeting voice message, for example, “Hello! Xiao Ming! Do you want to hear a story?” The smart device may send multiple first voice messages and try different volumes.

[0149] The second voice message is the voice message replied by the interaction object, for example, "OK, thank you!", "Please speak a little more quietly!".

[0150] The smart device determines whether the voiceprint of the second voice information matches the identification information voiceprint of the interaction object through the voiceprint. If the voiceprint matches, the smart device initiates the voice interaction process. The interaction object is further determined through voiceprint matching.

[0151] The voice interaction process may include multiple interaction scenarios such as chatting, question-and-answer consultation, and song ordering. Specifically, smart devices can implement the voice interaction process through multiple language models.

[0152] In an embodiment of the present application, if the smart device does not receive the second voice message within a preset time period after sending the first voice message, the smart device can adjust the volume and / or voice content of the first voice message to provoke the interactive object to feedback the voice.

[0153] In another embodiment of the present application, step 102 may specifically include the following sub-steps:

[0154] Sub-step S21, the smart device sends the interactive object information to the control device; the control device is used to obtain reference feature information, and use the reference feature information to compare with the distance measurement information; if the comparison result meets the preset requirements, a voice interaction instruction is generated;

[0155] Specifically, the reference feature information may include: a reference distance, a reference signal strength, a reference volume, and a reference voice content. The reference feature information may be stored in a preset feature database.

[0156] The interactive object has corresponding reference feature information. If the interactive object information includes the identification information of the interactive object, the control device can obtain the corresponding reference feature information from the feature database according to the identification information of the interactive object. If the interactive object information does not include the identification information of the interactive object, the smart device can obtain general reference feature information.

[0157] The control device compares the distance in the current ranging information with the reference distance, and / or compares the signal strength in the current ranging information with the reference signal strength; and determines whether the preset requirements are met based on the comparison result. For example, if the distance of the current ranging information is greater than or equal to the reference distance, and the signal strength of the current ranging information is greater than or equal to the reference signal strength, the control device determines that the preset requirements are met. For another example, as long as the distance of the current ranging information is greater than or equal to the reference distance, the smart device determines that the preset requirements are met. For another example, as long as the signal strength of the current ranging information is greater than or equal to the reference signal strength, the smart device determines that the preset requirements are met. Of course, the technology in the field can also set other preset requirements according to actual needs, and the embodiments of the present application are not limited to this.

[0158] In sub-step S22, the smart device sends a voice message after receiving the voice interaction instruction sent by the control device.

[0159] In the embodiment of the present application, the voice interaction instruction may include reference feature information. The smart device may send voice information according to the reference feature information in the voice interaction instruction.

[0160] Furthermore, the smart device can adjust the voice volume and voice content according to parameters such as reference feature information, current distance measurement information, identification information of the interactive object, etc., so as to flexibly and appropriately send out voice information.

[0161] In an embodiment of the present application, the smart device can also determine the volume, distance measurement information, and voice quality information of the interactive object used in the voice interaction process; the smart device uses the volume, distance measurement information, and voice quality information to update the feature database. The voice quality information can be information that measures the voice quality of the interactive object, such as the signal-to-noise ratio.

[0162] Specifically, smart devices can iterate the feature database through deep learning, continuously optimize the reference feature information, and thus optimize the voice interaction process.

[0172] In the embodiment of the present application, the smart device may also be provided with a biometric information sensor, such as an infrared sensor. When the biometric information sensor detects biometric information of an interactive object around, the smart device transmits a second wireless frame through a wireless ranging communication device to search for the interactive object around.

[0173] In another example of the present application, the interactive object may be provided with a motion sensor, and the motion sensor may detect whether the interactive object is moving. When the movement of the interactive object is detected, the wireless ranging communication device of the interactive object sends a first wireless frame to the wireless ranging communication device of the smart device. When the interactive object does not move, the wireless ranging communication device of the interactive object does not send the first wireless frame to save power.

[0174] Step 202: Send out a voice message according to the interaction object information.

[0175] In the embodiment of the present application, voice information can be actively sent out according to the interaction object information, so that voice interaction can be actively established with the interaction object.

[0176] Specifically, it can be determined based on the distance measurement information whether an interactive object is within a preset distance range relative to the smart device. If an interactive object is within the preset distance range, a voice message can be sent.

[0177] Furthermore, if the interaction object information also includes the identification information of the interaction object, the smart device can make a voice call based on the identification information of the interaction object. If the communication information does not include the identification information of the interaction object, the smart device can send a voice message to inquire about the identity.

[0178] In an embodiment of the present application, the wireless ranging communication device of the smart device can communicate with the wireless ranging communication device of the interactive object, and the interactive object information can be determined based on the communication information; based on the interactive object information, voice information can be actively sent out, so as to actively guide the interactive object to establish voice interaction with the smart device.

[0179] In an embodiment of the present application, the wireless ranging communication device of the interactive object may be provided with a reminder device, which may remind the interactive object by emitting light, flashing, vibrating, etc., to inform the interactive object that voice interaction is being performed with the smart device.

If the interactive object information includes the identification information of the interactive object, the corresponding reference feature information can be obtained from the feature database according to the identification information of the interactive object. If the interactive object information does not include the identification information of the interactive object, the general reference feature information can be obtained.

[0183] Sub-step S32, comparing the reference feature information with the distance measurement information;

[0184] The distance in the current ranging information can be compared with the reference distance, and / or the signal strength in the current ranging information can be compared with the reference signal strength; and whether the preset requirements are met can be determined based on the comparison results. For example, if the distance of the current ranging information is greater than or equal to the reference distance, and the signal strength of the current ranging information is greater than or equal to the reference signal strength, it is determined to meet the preset requirements. For another example, as long as the distance of the current ranging information is greater than or equal to the reference distance, it is determined to meet the preset requirements. For another example, as long as the signal strength of the current ranging information is greater than or equal to the reference signal strength, it is determined to meet the preset requirements. Of course, the technology in the field can also set other preset requirements according to actual needs, and the embodiments of the present application are not limited to this.

[0185] Sub-step S33: if the comparison result meets the preset requirement, a voice message is sent.

[0186] In the embodiment of the present application, voice information can be issued based on the reference feature information.

[0187] Furthermore, the smart device can adjust the voice volume and voice content according to parameters such as reference feature information, current distance measurement information, identification information of the interactive object, etc., so as to flexibly and appropriately send out voice information.

[0188] In the embodiment of the present application, it is also possible to further determine whether to send a voice message through voiceprint judgment processing. Specifically, the step of sending a voice message by a smart device may include: the smart device sends a first voice message; the smart device receives a second voice message of the interactive object; the smart device determines whether the second voice message matches the identification information of the interactive object through the voiceprint; if the voiceprint matches successfully, the smart device initiates a voice interaction process. The interactive object is further determined through voiceprint matching.

[0189] In an embodiment of the present application, if the second voice message is not received within a preset time period after the first voice message is sent, the volume and / or voice content of the first voice message can be adjusted to provoke the interactive object to feedback the voice.

[0190] In another embodiment of the present application, step 202 may include the following sub-steps:

[0191] Sub-step S41, sending the interactive object information to a control device; the control device is used to obtain reference feature information, and use the reference feature information to compare with the distance measurement information; if the comparison result meets the preset requirements, a voice interaction instruction is generated;

[0192] Sub-step S42, receiving the voice interaction instruction sent by the control device, and issuing voice information according to the voice interaction instruction.

[0193] In the embodiment of the present application, the voice interaction instruction may include reference feature information. The voice information may be issued according to the reference feature information in the voice interaction instruction.

[0194] Furthermore, the voice volume and voice content can be adjusted according to parameters such as reference feature information, current distance measurement information, identification information of the interactive object, etc., so as to flexibly and appropriately send out voice information.

[0195] In an embodiment of the present application, the volume, ranging information, and voice quality information of the interactive object used in the voice interaction process can also be determined; the volume, ranging information, and voice quality information are used to update the feature database.

[0196] Specifically, smart devices can iterate the feature database through deep learning, continuously optimize the reference feature information, and thus optimize the voice interaction process.
