DETAILED DESCRIPTION

[0016] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0018] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Example like Figures 1 to 3 As shown, in one embodiment of the present invention, an outdoor communication method of the present invention includes a Bluetooth headset and a relay device, the relay device includes a communication unit and a Bluetooth unit, Bluetooth wireless communication is established between the Bluetooth headset and the relay device through a first connection, the Bluetooth wireless communication includes sending uplink and downlink data, and control data, and communication is established between the communication unit and the Bluetooth unit through a second connection.

[0022] Bluetooth headsets can be TWS, OWS, neck-worn headsets, head-worn headsets, etc. The full name of TWS is True Wireless Stereo. TWS technology is developed based on Bluetooth chip technology. Its working principle is that the left and right earphones are divided into main earphones and auxiliary earphones. The mobile phone or other electronic devices are connected to the main earphone, and then the main earphone is quickly connected to the auxiliary earphone wirelessly to achieve true Bluetooth left and right channel wireless separation. OWS earphones are Open Wearable Stereo open wearable stereo earphones. Compared with TWS earphones, the main difference is that they adopt an open structure design, which does not need to be put into the ears when used, ensuring the comfort of long-term wearing.

[0023] The main function of the relay device is to extend the distance of network transmission by resending or forwarding data signals. The relay device can be, but is not limited to, an earphone box, a smart bracelet, a smart watch, etc.

[0024] A Bluetooth module refers to an independent functional module in the application of Bluetooth technology. It can realize the reception and transmission and processing of Bluetooth data. The main function of the Bluetooth module is to transmit and communicate data between different devices, thereby realizing the interconnection between devices. In this solution, the Bluetooth module is connected to the Bluetooth headset. The Bluetooth module can also be used as a unit for bridging with other brands of headsets. After bridging, the Bluetooth module receives Bluetooth signals from different headset products, and then transmits them to the communication unit, which then sends them to other devices.

[0025] The communication unit can adopt traditional Bluetooth / WIFI / Zigbee / Lora / LTE CAT1, etc. to adapt to different application scenarios and frequency restrictions of different countries, and is used to receive encoded or decoded data. Communication units using different communication methods can adapt to different application scenarios. By dynamically controlling the Bluetooth unit and the communication unit, communication units using different communication methods can communicate with each other.

[0026] The method comprises: S101, after the Bluetooth headset is triggered (the triggering method is, for example, opening the headset cover, turning on the headset, or pressing a button, or voice triggering), a first connection and a second connection are established, and the order of the first connection and the second connection is not limited; This solution uses LE Audio technology to complete the first connection. Establishing the first connection through LE Audio technology can reduce the transmission delay of the first connection. However, it is not limited to LE Audio connection. Any BT connection can be used. The BT connection can send uplink and downlink data, as well as control data.

[0027] LE Audio is an audio technology standard of the Bluetooth Special Interest Group (SIG). It is based on low-power Bluetooth 5.2, adopts the ISOC (isochronous) architecture, and introduces the innovative LC3 audio coding algorithm. It has lower latency and higher transmission quality. It also supports functions such as multi-device connection and audio sharing.

[0028] S201, after the first connection and the second connection are established, the Bluetooth headset or the relay device triggers a networking command, and the networking command is sent to the Bluetooth unit through the first connection; S301, after receiving the networking command information, the Bluetooth unit determines and selects a networking mode according to the current number of networking devices, the networking mode at least includes the Bluetooth unit independently completing the networking command, the communication unit independently completing the networking command, and the Bluetooth unit and the communication unit jointly completing the networking command, and starts to build a network after determining the networking mode; S401, when the network is established, the Bluetooth unit or the communication unit transmits the network establishment completion instruction to the Bluetooth headset through the Bluetooth unit. In the case of distributed networking, the Bluetooth unit or the communication unit selects a master node to confirm the network establishment completion, and then sends the network establishment completion command to the Bluetooth headset through the Bluetooth unit.

[0029] S501, after the Bluetooth headset receives the information that the networking is completed, the microphone starts to collect data, and processes and encodes the voice data and sends it to the Bluetooth unit; at the same time, the Bluetooth headset receives the encoded data sent by the Bluetooth unit for decoding and playback; S601, the Bluetooth unit receives the voice data sent by the Bluetooth headset and sends it to the communication unit, and the communication unit transmits it to other surrounding nodes in the established network through the wireless network.

[0030] Further, in one embodiment, the networking method in step S301 is specifically: When the number of networking devices is small, the Bluetooth unit independently completes the networking command, turns off the communication unit, puts it into a low-power state, and starts networking. The Bluetooth unit is responsible for completing the self-organizing network function and the Bluetooth unit function, and is responsible for communicating with the Bluetooth headset. This solution has the advantage of reducing the power consumption of the entire device; When the number of networking devices is greater than the maximum number of devices that the Bluetooth unit can network, or the communication unit is non-Bluetooth communication, the communication unit independently completes the networking command, that is, sends the networking command to the communication unit. After receiving the networking command, the communication unit starts to build a network according to the surrounding devices. The communication unit is responsible for completing the self-organizing network function; When the communication unit adopts Bluetooth communication, the Bluetooth unit and the communication unit jointly complete the networking command, that is, after the Bluetooth unit receives the networking command from the Bluetooth headset, it completes the establishment of the self-organizing network together with the communication unit through distributed networking, in which the communication unit is responsible for receiving data from some peripheral devices, and the Bluetooth unit completes the reception of some peripheral device data and the transmission of its own data. The communication unit and the Bluetooth unit complete the distributed networking through internal coordination. The distributed here means that there are two Bluetooth chips to complete a network. Two Bluetooth chips can achieve more networking people, breaking through the number limit and distance limit of a single Bluetooth chip.

[0031] Furthermore, in one embodiment, when the communication unit adopts the Bluetooth communication mode, the communication unit extends the communication transmission distance through the first power amplifier.

[0032] When the communication unit adopts Bluetooth communication, a distributed self-organizing network can be used to realize multi-person Bluetooth communication. Due to the limitation of Bluetooth bandwidth, the self-organizing network realized through Bluetooth cannot break through the number of people and distance limitations. Therefore, PA (power amplifier) ​​is added during Bluetooth communication to achieve long-distance transmission. In this solution, the communication unit acts as RX (receive), and the Bluetooth unit acts as the TX (send) and RX (receive) of the communication unit to jointly complete the establishment of a self-organizing network. According to this distributed networking method, the communication bandwidth limitation of a single Bluetooth chip can be broken.

[0033] Furthermore, in one of the embodiments, the Bluetooth unit extends the communication transmission distance through a second power amplifier.

[0034] Furthermore, in one embodiment, when networking, the power of the Bluetooth unit is adaptively adjusted according to different networking modes, that is: When the Bluetooth unit completes the networking command independently, the communication unit is turned off and the second power amplifier of the Bluetooth unit is enabled at the same time, which can reduce the power consumption of the whole device on the basis of completing the networking function and the communication function with the Bluetooth headset; When the communication unit completes the networking command independently, the Bluetooth unit sends the networking command to the communication unit after receiving the networking command from the Bluetooth headset, and turns off the second power amplifier of the Bluetooth unit; (since the communication distance between the Bluetooth unit and the Bluetooth headset is short, the second power amplifier is not needed).

[0035] When the Bluetooth unit and the communication unit jointly complete the networking command, the second power amplifier of the Bluetooth unit can be optionally turned off or enabled; when the second power amplifier is turned off, the power consumption is reduced, and when the second power amplifier is enabled, the communication distance is extended. There is no restriction here.

[0036] Furthermore, in one of the embodiments, in step S101, when establishing the first connection, the Bluetooth unit establishes Bluetooth connections with the Bluetooth left earphone and the Bluetooth right earphone respectively, and in step S501, when the voice data is processed and encoded and then sent to the Bluetooth unit, the Bluetooth left earphone and the Bluetooth right earphone both upload the voice data, or, in order to reduce power consumption, the Bluetooth left earphone and the Bluetooth right earphone select one to upload the voice data. That is, there are at least two implementation schemes here, one is that the Bluetooth left earphone and the Bluetooth right earphone can both upload voice data, and the other is that in order to further reduce power consumption, one of the Bluetooth left earphone and the Bluetooth right earphone can be selected to upload voice data.

[0037] The above describes an outdoor communication method in an embodiment of the present application. The following describes an outdoor communication device and system in an embodiment of the present application. Figure 2 and Figure 3 An embodiment of an outdoor communication device of the present application includes a relay device, wherein the relay device includes a communication unit and a Bluetooth unit. The communication unit is used to receive the encoded or decoded data and send it to the Bluetooth unit via a wired method such as a serial port / USB / I2C; the communication unit also includes a wireless transmitter, receiver or transceiver that can send and receive wireless communication signals.

[0038] The Bluetooth unit is used to send the encoded and decoded data to the Bluetooth headset and communicate with the Bluetooth headset; Also includes a memory and at least one processor, wherein the memory stores instructions; The at least one processor calls the instructions in the memory to enable the outdoor communication device to execute an outdoor communication method as described in any one of the above embodiments.

[0039] The relay device can be used as a bridge device alone. After entering the bridge mode, the relay device can be bridged with any headset with a bridge function. After the bridge mode is established, the relay device sends out the voice data information of the headset and can also receive information from other relay devices.

[0040] In another embodiment of an outdoor communication device, the communication unit is connected to a first power amplifier, and the Bluetooth unit is connected to a second power amplifier.

[0041] When different communication units need to be networked, the functions of the communication unit and the Bluetooth unit are dynamically adjusted. The communication unit can be turned off, and the Bluetooth unit can be used to build an ad hoc network for communication, or both the communication unit and the Bluetooth unit can enable the power amplifier (PA) for communication. There is no restriction here, and the final choice needs to be made according to the definition of the product.

[0042] As an embodiment of an outdoor communication system, the system further includes a Bluetooth headset, a mobile terminal or a smart wearable device, and an outdoor communication device as described above. The mobile terminal is such as a mobile phone, a tablet, etc., and the smart wearable device is such as a smart bracelet, a smart watch, smart glasses, etc.
