Moreover, the present application may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

Augmented Reality (AR) technology refers to a display technology that applies virtual information to a real world so that the real world and a virtual world are superimposed on the same screen in real time or coexist in a space. Currently, AR technology may be implemented through AR glasses.

In the related art, the AR glasses can communicate with the server through the network, thereby enabling other mobile terminals, such as AR glasses, a mobile phone, or a watch, to communicate with the server. Communication between the AR glasses and the mobile terminal can also be achieved through Wi-Fi or Bluetooth connection. However, in the process of communication between the AR glasses and other mobile terminals, the strength of the network signal is relied on, and if the network signal is not good at the position where one of the AR glasses is located. It is easy to cause the AR glasses to fail to effectively communicate with other mobile terminals. And the communication can be realized in a short-distance range of several meters or dozens of meters only by adopting Bluetooth, Wi-Fi and the like.

Referring to fig. 1, the present application provides AR glasses 100, where the AR glasses 100 include a glasses body 10 and a Lora module 20. The Lora module 20 is installed in the glasses body 10, and the AR glasses 100 communicate with a mobile terminal (not shown) through the Lora module 20. The Lora module 20 is capable of directly transmitting and receiving data to and from the mobile terminal.

As can be understood by those skilled in the relevant art, the Lora technology is a long-distance wireless transmission technology based on a spread spectrum technology, and belongs to one of Low-Power Wide-Area Network (LPWAN) technologies. The low-power-consumption wide area network technology is a wireless communication technology for the communication requirements of long distance and low power consumption in the Internet of things, and has the characteristics of low cost, low power consumption, wide coverage and large connection.

Specifically, the eyeglass body 10 includes a frame 11, lenses 12, and a frame 13. The lens 12 is used as a viewing window of the AR glasses 100 and is fixedly mounted in the frame 11, and the mounting manner is not limited, for example, the lens can be fastened, snapped, or bonded. The lens 12 can display the display image generated by the AR glasses 100 to the user, and the lens 12 may be made of glass, plastic, or the like. The frame 13 includes two frame legs 131 extending from two ends of the frame 11, the frame legs 131 are substantially elongated, the two frame legs 131 can be symmetrically disposed, and in some examples, the frame legs 131 can rotate a certain angle around a connection point where the frame legs 131 are connected to the frame 11. The AR glasses 100 may be worn on the user's head by the frame feet 131.

The Lora module 10 is mounted in the frame 13 and may operate at 433 mhz, 868 mhz, 915 mhz, etc. It should be noted that the communication rate of the Lora module 10 is positively correlated with the operating frequency, and the communication distance of the Lora module 10 is negatively correlated with the operating frequency. That is, the higher the operating frequency of the Lora module 10 is, the faster the transmission rate of the Lora module 10 is, and accordingly, the shorter the transmission distance that the Lora module 10 can effectively transmit.

Further, the Lora module 10 includes a first Lora sub-module 21 and a second Lora sub-module 22. The first Lora sub-module 21 and the second sub-frame are symmetrically arranged in the frame legs 131 at the two ends of the frame 11. The AR glasses 100 may wirelessly communicate with other smart wearable devices such as a smart band and a smart watch or mobile terminals such as a mobile phone through the first Lora sub-module 21 or the second Lora sub-module 22. In this application, the working frequency of the first Lora sub-module 21 is different from the working frequency of the second Lora sub-module 22, and the working frequency of the first Lora sub-module 21 is smaller than the working frequency of the second Lora sub-module 22, that is, the communication rate of the first Lora sub-module 21 is lower than that of the second Lora sub-module 22, but the communication distance of the first Lora sub-module 21 is higher than that of the second Lora sub-module 22. The specific operating frequency of the first Lora sub-module 21 and the second Lora sub-module 22 is not limited, for example, the operating frequency of the first Lora sub-module 21 may be 433 mhz, and the operating frequency of the second Lora sub-module 22 may be 915 mhz. So, through setting up first Lora submodule 21 and second Lora submodule 22 for AR glasses can select different Lora submodule to communicate with mobile terminal according to the distance of difference.

Referring to fig. 2, for example, in some examples, both mobile terminal 1 and mobile terminal 2 may be communicatively coupled to Lora module 10 of the AR glasses, where mobile terminal 1 is 500 meters away from the AR glasses and mobile terminal 2 is 5000 meters away from the AR glasses. The AR glasses 100 may communicate with the mobile terminal 2 through the first Lora sub-module 21 and the AR glasses 100 may communicate with the mobile terminal 1 through the second Lora sub-module 22.

Further, the first Lora sub-module 21 includes a first data transceiver module 211 and a second antenna 212 extending from the first data transceiver module 211 to a side away from the frame 11, and the second Lora sub-module 22 includes a second data transceiver module 221 and a second antenna 222 extending from the second data transceiver module 221 to a side away from the frame 11. The first data transceiver module 211 and the second data transceiver module 221 are configured to receive and transmit communication data. The first antenna 212 and the second antenna 222 are used to convert a guided wave of communication data propagated by the data transceiver module on the transmission line into an electromagnetic wave propagated in an unbounded medium (free space), or convert an electromagnetic wave propagated in an unbounded medium into a guided wave propagated on the transmission line to be received by the data transceiver module on the transmission line.

It can be understood that first Lora submodule 21 and second Lora submodule 22 are installed respectively in the mirror holder foot 131 at picture frame 11 both ends, because AR glasses 100 is worn on the user head through mirror holder foot 131, mirror holder foot 131 is usually longer, can make first Lora submodule 21 and second Lora submodule 22 hold the battery of bigger capacity, and make first Lora submodule 21 and second Lora submodule 22 transmission power increase, have improved the communication distance and the communication rate of first Lora submodule 21 and second Lora submodule 22. In addition, in the mirror holder leg 131, the first antenna 212 and the second antenna 222 can be extended, and the transmission efficiency of the first Lora sub-module 21 and the second Lora sub-module 22 can be improved, so that the communication distance and the communication rate of the first Lora sub-module 21 and the second Lora sub-module 22 are further improved. Thus, the AR glasses realize remote communication through the Lora module 20 and can ensure communication efficiency.

Referring to fig. 3 and 4, the first data Transceiver module 211 includes a first Transceiver (Transceiver1) and a first RF switch (RF switch 1) connected to the Transceiver 1. The second Lora submodule 22 includes a second Transceiver (Transceiver2) and a second rf switch (rfswitch 2) connected to the Transceiver 2. The RF switch 1 is connected to the first antenna 212 and the RF switch 2 is connected to the second antenna 222. The transmitter is a radio transmitter and a receiver which are mounted on one component and share a part of the same circuit, and the data Transceiver module can receive or transmit data through the transmitter. The RF switch is used for controlling the operating state of a Transceiver, and the operating state of the Transceiver comprises a receiving state and a transmitting state.

Referring to fig. 5, the present application provides a control method for AR glasses 100, the control method includes the steps of:

s12: pairing the mobile terminal corresponding to the pairing signal according to the received pairing signal;

s14: calculating the distance between the mobile terminal and the pairing signal;

s16: judging whether the distance value of the mobile terminal is larger than a first preset value or not; and

s18: and when the distance value of the mobile terminal is greater than a first preset value, controlling the first Lora submodule to send data to the mobile terminal.

Referring to fig. 6, the present embodiment provides a control device 200. The control device 200 includes a pairing module 12, a calculation module 14, a determination module 16, and a first control module 18.

The determining module 16 may be configured to determine whether the distance value of the mobile terminal is greater than a first preset value.

Referring to fig. 7, the control method of the present application may be implemented by the AR glasses 100, and the AR glasses 100 include a processor 30 connected to the Lora module.

The processor 30 may be configured to pair the mobile terminal corresponding to the pairing signal according to the received pairing signal and calculate a distance to the mobile terminal according to the pairing signal. The processor 30 may be further configured to determine whether the distance value of the mobile terminal is greater than a first preset value, and control the first Lora sub-module 21 to send data to the mobile terminal when the distance value of the mobile terminal is greater than the first preset value.

Referring to fig. 8, AR glasses 100 provided herein include one or more processors 30, a memory 40, and one or more programs 42, where the one or more programs 42 are stored in the memory 40 and executed by the one or more processors 30, and where the program 42 is executed by the processor 30 to perform the instructions of the control method.

Referring to fig. 9, the present application provides one or more non-transitory computer-readable storage media 50 containing computer-executable instructions that, when executed by one or more processors 30, cause the processors 30 to perform a control method.

In the AR glasses 100, the control method, the control device 200, and the computer-readable storage medium 40 according to the embodiments, the distance between the AR glasses 100 and the mobile terminal may be calculated according to the pairing signal of the mobile terminal, the first Lora sub-module 21 may be controlled to transmit data to the mobile terminal at a long distance, so as to ensure that data can be normally transmitted to the mobile terminal, and the second Lora sub-module 22 may be controlled to transmit data to the mobile terminal at a short distance, so as to improve data transmission efficiency. Thus, the AR glasses 100 can communicate with other mobile terminals without a server, avoiding that the AR glasses 100 cannot effectively communicate with other mobile terminals due to poor network signals.

The control device 200 may be hardware or software preinstalled on the AR glasses 100 and may perform a control method when the runtime is started on the AR glasses 100. For example, the control device 200 may be an underlying software code segment on the AR glasses 100 or part of an operating system. In this way, when the AR glasses 100 generate data, the first Lora sub-module 21 may be controlled or the second Lora sub-module 22 may be controlled to transmit the data to the mobile terminal.

In some embodiments, the control device 200 may be part of the AR glasses 100. Alternatively, the AR glasses 100 include a control device 200.

In some embodiments, the control device 200 may be a discrete component assembled in such a way as to have the aforementioned functions, or a chip having the aforementioned functions in the form of an integrated circuit, or a piece of computer software code that causes a computer to have the aforementioned functions when run on the computer.

In some embodiments, the control device 200 may be a stand-alone or add-on peripheral component to a computer or computer system as hardware. The control device 200 may also be integrated into a computer or computer system, for example, the control device 200 may be integrated into the processor 30 when the control device 200 is part of the AR glasses 100.

In some embodiments where the control device 200 is part of the AR glasses 100, as software, code segments corresponding to the control device 200 may be stored on the memory 40 and executed on the processor 30 to implement the aforementioned functions. Or the control device 200 includes one or more programs described above, or the one or more programs described above include the control device 200.

In some embodiments, computer-readable storage medium 50 may be a storage medium built into AR glasses 100, such as memory 40, or a storage medium that is removably inserted into AR glasses 100, such as an SD card.

The first preset value is a predefined value, and the first preset value may be set when the AR glasses 100 leave a factory from a manufacturer, or may be set by a user. The first preset value may be stored in the computer-readable storage medium 50, and called by the processor 30 or the control device 200.

The data may include content generated when the user interacts with the AR glasses 100, such as user speech, text, or captured 3D images, video, etc. recorded by the AR glasses 100.

Referring to fig. 7 and 10, in particular, the processor 30 includes a wireless Access Point (AP) and a Microcontroller Unit (MCU) connected to the AP. The processor 30 is connected to the first and second Lora sub-modules 21 and 22 through the MCU. The AP is used as a wireless switch of the wireless network, and is also a core of the wireless network, and the processor 30 is connected with the mobile terminal corresponding to the pairing signal through the AP. The processor 30 processes the pairing signal, other data, or data to be transmitted received by the first and second Lora sub-modules 21 and 22 through the AP. The MCU is used to control the switching of the operation between the first Lora sub-module 21 and the second Lora sub-module 22.

Further, the MCU is connected to Transceiver1 and Transceiver2, respectively. When the AR glasses 100 are not paired with the mobile terminal, the MCU may control the driver 1 and the driver 2 to be turned on, and control the RF switch 1 and the rfswitch 2 so that the driver 1 and the driver 2 are both in a receiving state. The first Lora sub-module 21 and the second Lora sub-module 22 are enabled to receive the pairing signal transmitted from the mobile terminal. When the first Lora sub-module 21 or the second Lora sub-module 22 receives the pairing signal, the AP may perform signal processing on the pairing signal, and the name of the mobile terminal corresponding to the pairing signal may be displayed on the lens 12 according to the pairing signal. The specific display form is not limited, and for example, the display form may be a list. The user may select the mobile terminal to be paired. The selection mode can be voice selection, key selection or eyeball sight track selection, and the like, so that communication with the selected mobile terminal is realized.

For example, in some examples, if the first Lora sub-module 21 and the second Lora sub-module 22 receive three pairing signals, A, B and C respectively, names of mobile terminals corresponding to the three pairing signals may be displayed in the lens 12 in a list form, and if the user selects to pair with B by voice, the AR glasses 100 establish communication with the mobile terminal corresponding to B, so that the AR glasses 100 may transmit data to the mobile terminal corresponding to B or receive data transmitted from the mobile terminal corresponding to B.

The AP may also process data to be transmitted by the AR glasses 100 in the course of the AR glasses 100 communicating with the paired mobile terminal. The MCU may calculate a distance from the mobile terminal according to the attenuation degree of the pairing signal, compare the calculated distance value with a first preset value, determine that the Transceiver1 is in a working state if the distance value between the AR glasses 100 and the paired mobile terminal is greater than the first preset value, and control the RF switch 1 so that the Transceiver1 is in a transmission state, so that the first Lora submodule 21 may transmit the data processed by the AP to the paired mobile terminal. If the distance value between the AR glasses 100 and the paired mobile terminal is less than or equal to the first preset value, it is determined that the Transceiver2 is in the working state, and the switch 2 is controlled so that the Transceiver2 is in the sending state, so that the second Lora sub-module 22 can send the data processed by the AP to the mobile terminal.

It can be understood that the effective communication distance of the first Lora sub-module 21 is greater than the effective communication distance of the second Lora sub-module 22, and the second Lora sub-module 22 is higher than the transmission rate of the first Lora sub-module 21, when the distance value is greater than a first preset value, the reliable communication with the mobile terminal can be effectively guaranteed through the first Lora sub-module 21, and when the distance value is less than or equal to the first preset value, the data transmission efficiency can be improved through the second Lora sub-module 22. For example, the first preset value is 10, the effective communication distance of the first Lora sub-module 21 is 25 km, the transmission speed is up to 5 million per second, the effective communication distance of the second Lora sub-module 22 is 10 km, and the transmission speed is up to 50 million per second. If the distance value between the AR glasses 100 and the paired mobile terminal is greater than 10 thousand, the first Lora submodule 21 is used for communication, and if not, the second Lora submodule 22 is used for communication.

Referring to fig. 11, in some embodiments, the control method further includes the steps of:

s20: judging the type of the data when the distance value of the mobile terminal is smaller than or equal to a first preset value;

s22: if the data is the first type data, controlling the first Lora sub-module to send the data to the mobile terminal;

s24: and if the data is the second type data, controlling the second Lora sub-module to send the data to the mobile terminal.

Referring further to fig. 6, in some embodiments, the control apparatus 100 further includes a second determining module 20 and a second control module 22. The step S20 may be implemented by the second determination module 20, the step S22 may be implemented by the first control module 18, and the step S24 may be implemented by the second control module 22.

Or, the second determining module 20 is configured to determine the type of the data when the distance value of the mobile terminal is smaller than or equal to the first preset value.

The first control module 18 is further configured to control the first Lora sub-module 21 to send data to the mobile terminal if the data is the first type data.

The second control module 22 is configured to control the second Lora sub-module 22 to send data to the mobile terminal if the data is the second type data.

In some embodiments, the processor 30 is configured to determine the type of the data when the distance value of the mobile terminal is less than or equal to a first preset value, and the processor 30 is further configured to control the first Lora sub-module 21 to send the data to the mobile terminal if the data is the first type of data and control the second Lora sub-module 22 to send the data to the mobile terminal if the data is the second type of data.

The first type of data may be text format, voice format, etc. type of data. The second type of data may be data of a video format or the like.

It is understood that the AR glasses 100 may interact in a variety of forms when interacting with the paired mobile terminal. For example, the form of interaction may be voice, text, or video, among others. Because different interaction forms generate different data types and different content sizes of different types of data, different interaction forms have different requirements on transmission rates, for example, text and voice interaction can be normally interacted only within 300 bytes per second, and video interaction can require a transmission rate of 2 million per second to realize normal interaction. And when the distance value between the AR glasses 100 and the paired mobile terminal is less than or equal to the first preset value, both the first Lora sub-module 21 and the second Lora sub-module 22 can implement communication with the paired mobile terminal, and the transmission power of the first Lora sub-module 21 is less than that of the second Lora sub-module 22 under the same distance transmission.

Therefore, if the distance value from the mobile terminal is less than or equal to the first preset value, the processor 30 determines the interaction mode adopted when the AR glasses 100 interact with the paired mobile terminal, and determines the type of data to be sent by the AR glasses 100, if the data is the first type of data, the processor 30 may control the first Lora sub-module 21 to transmit the data to the paired mobile terminal, and if the data is the second type of data, the processor 30 may control the second Lora sub-module 22 to transmit the data to the paired mobile terminal. Therefore, the AR glasses 100 can be normally interacted with the matched mobile terminal, power consumption is reduced, and cruising ability of the AR glasses 100 is improved.

For example, in some examples, the first Lora sub-module 21 and the second Lora sub-module 22 of the AR glasses 100 are both enabled to transmit data to the mobile terminal a while the AR glasses 100 are in communication with the mobile terminal a. When the AR glasses 100 make a voice call with the mobile terminal a, the processor 30 controls the first Lora sub-module 21 to transmit voice data to the mobile terminal a. When the AR glasses 100 make a video call with the mobile terminal a, the processor 30 controls the second Lora sub-module 22 to transmit video data to the mobile terminal a.

In other examples, the processor 30 may directly determine whether the size of the transmission data is smaller than or equal to a predetermined value, control the first Lora sub-module 21 to transmit the data to the mobile terminal when the size of the data is smaller than or equal to the predetermined value, and control the second Lora sub-module 22 to transmit the data to the mobile terminal when the size of the data is larger than the predetermined value.

Referring to fig. 12, in some embodiments, after step S24, the method further includes the steps of:

s242: comparing the data transmission speed value of the second Lora sub-module with a second preset value;

s244: and controlling the first Lora sub-module to send data to the mobile terminal when the data transmission speed value of the second Lora sub-module is smaller than a second preset value.

Referring further to fig. 6, in some embodiments, the control device 200 further includes the comparing module 24, and the step S20 can be implemented by the comparing module 24, and the step S244 can be implemented by the first control module 18.

Alternatively, the comparing module 24 is used for comparing the data transmission speed value of the second Lora sub-module 22 with a second preset value.

The first control module 18 is further configured to control the first Lora sub-module 21 to send data to the mobile terminal when the data transmission speed value of the second Lora sub-module 22 is smaller than or equal to a second preset value.

In some embodiments, the processor 30 may be configured to compare the data transmission speed value of the second Lora sub-module 22 with a second preset value. The processor 30 may be further configured to control the first Lora sub-module 21 to send data to the mobile terminal when the data transmission speed value of the second Lora sub-module 22 is smaller than or equal to a second preset value.

Specifically, since the operating frequency of the second Lora sub-module 22 is higher than that of the first Lora sub-module 21, the higher the frequency, the shorter the wavelength, the weaker the diffraction (diffraction effect) capability, but the stronger the penetration capability (invariable direction), the larger the energy loss of the signal penetration. When an obstacle exists between the AR glasses 100 and the mobile terminal, the energy lost when the second Lora sub-module 22 propagates data is larger than the energy lost when the first Lora sub-module 21 propagates data, the transmission rate is in positive correlation with the energy, and the second Lora sub-module 22 is more prone to communication blockage than the first Lora sub-module 21. Therefore, when the processor 30 controls the second Lora sub-module 22 to transmit data to the mobile terminal, the processor 30 may further record a data transmission speed value of the second Lora sub-module 22 and compare the data transmission speed value with a second preset value. When the data transmission speed value of the second Lora sub-module 22 is less than or equal to the second preset value, it can be said that the communication of the second Lora sub-module 22 is blocked or the propagation rate of the second Lora sub-module 22 is less than the transmission rate of the first Lora sub-module 21, the second Lora sub-module 22 is controlled to stop sending data, and the first Lora sub-module 21 is controlled to send data to the paired mobile terminal. And if the data transmission speed value of the second Lora submodule 22 is greater than a second preset value, continuing to control the second Lora submodule to send data to the mobile terminal. Therefore, the processor 30 may control the first Lora sub-module 21 to send data to the mobile terminal, which ensures that the AR glasses 100 can communicate normally.

The above examples only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
