As shown in fig. 1, in one embodiment, the method includes:

step 101: the first device and the second device initiate a communication channel.

In the technical solution of this embodiment, the first device and the second device both provide a communication channel, so as to implement data transmission between different devices. The data channels refer to different communication modes, such as a Universal Serial Bus (USB) channel, a bluetooth channel, a wireless local area network (WIFI) channel, and the like, and may also be communication channels such as Near Field Communication (NFC) and serial ports.

In some of these embodiments, where the communication channel comprises a WIFI channel, this step 101 comprises:

in the case where the communication channel includes a USB channel, the enabling the communication channel includes:

and initializing Bluetooth service, starting Gatt host service, and sending advertisement information.

It should be noted that in this embodiment, the number of devices in the communication system may be more, and the plurality of devices may be connected by networking in a similar manner, and in this embodiment, only the first device and the second device are described as an example.

As shown in fig. 2, WIFI may implement data transmission based on a UDP (User Datagram Protocol ) protocol and TCP (Transmission Control Protocol, transmission control protocol), where the two are mainly different in that the UDP protocol supports one-to-many or many-to-one data transmission, while the TCP protocol only supports one-to-one data transmission, and the WIFI channel is responsible for setting up a network server and a client, which may be exemplified by using the UDP protocol to issue and receive broadcast messages, implement device discovery, and may be used for file and information transceiving by using the TCP protocol, and may also set up a CoAP (Costrained Application Protocal, constraint application protocol) protocol for low power devices (generally, internet of things devices), and implement transmission, reception and subscription of files and messages.

The Bluetooth channel can provide SPP (Serial Port Profile, serial port configuration) and Gatt (Generic Attribute Profile, general attribute configuration file) protocols, is responsible for the establishment of a slave and a host of the Bluetooth Gatt protocol, performs service function distribution and search, realizes device discovery, reads and writes simple messages, and establishes a server and a client of the Bluetooth SPP protocol, thereby realizing file and information transceiving.

The USB channel provides an AOA (Android Open Accessory Protocol, an Zhuokai source Accessory) protocol and is responsible for constructing and realizing file and information transceiving of an access (slave) and a Host.

As shown in fig. 2, in the technical solution of this embodiment, in order to conveniently and quickly implement communication connection between the first device and the second device, a networking core needs to be set in the device. The networking core of the embodiment mainly comprises a service starting module, a scheduling management module and an information management module.

The service starting module is mainly used for initializing each communication channel, starting the communication channel service of the equipment, monitoring the equipment, discovering the equipment and the like.

The dispatching management module is mainly used for realizing the functions of equipment networking registration, application networking registration, equipment distribution and channel switching.

The networking registration is mainly used for realizing the interactive processing function of identifying the information of the channels such as WIFI, bluetooth, USB and the like and permitting to join the networking.

The application networking registration is mainly used for realizing functions such as a distributed input method, a distributed file manager, a distributed information display application and the like, and the permission authentication using the distributed core function.

The equipment allocation is mainly used for realizing the selection and the scheduling of the equipment registered by networking before the transmission of information and files so as to optimize the completion of tasks. The channel switching is used for automatically adjusting channels according to different transmission types in the classified communication of WIFI, bluetooth and USB channels according to requirements, and task completion is guaranteed.

The information management module is mainly responsible for information collection, fusion, access and update, and more particularly, the information management module can realize networking registration of equipment and networking registration applied in the equipment by fusing equipment information.

Step 102: the first device and the second device exchange device information according to the communication channel.

After the first device and the second device start the communication channel, the first device and the second device need to complete the automatic networking.

In this embodiment, the device that needs networking starts the service, and then starts scheduling management and information management to implement information collection of the local device and the peripheral device.

After the communication channel is started, starting scheduling management, specifically, starting networking registration, starting application networking registration, starting equipment distribution and starting channel switching. Next, information of the local and peripheral devices is collected.

In some of these embodiments, the step of information gathering includes:

as shown in fig. 3, the local information is collected during the initialization phase of the communication channel, and the local information includes one or more of the following: WIFI ssid (Service Set Identifier, service set identification), WIFI mac (physical address), IP address (Internet Protocol ), bluetooth name, bluetooth mac, USB vendor name, mac address;

the peripheral device includes one or more of the following:

bluetooth name, bluetooth mac and universal unique identification code UUID (Universally Unique Identifier, universal unique identification code) of the peripheral equipment obtained through Bluetooth scanning;

More specifically, in one embodiment, the information collected by each device may be presented in the following manner: { deviceID (device number), IP, WIFI-ssid, WIFI-mac, bt-name, bt-mac, WIFI-state, bt-state, usb-state, app-info }.

The deviceID is the device number of the device, bt is the abbreviation of Bluetooth, bluetooth is referred to, WIFI-state and bt-state are referred to as WIFI state and Bluetooth state respectively, and app-info is the application state of the device.

The intra-group information for each device group may be presented in the following manner: { first device information, second device information, … }.

The relay information may be presented in the following manner: { Start device name: x1, channel type: x2, information: x3} { destination device name: y1, channel type: y2}.

The discovery information includes { device ID, channel type, channel status }; the hardware information comprises { WIFI information, bluetooth information and Usb information }; the connection information includes { channel type, channel state }; the peripheral equipment information comprises { Bluetooth name, bluetooth mac, WIFI name, WIFI mac }; the hotspot information includes { hotspot name, hotspot password, hotspot IP }.

It will be appreciated that the format of the information and the content of the information may be adjusted according to the need in the implementation, which is not further limited in this embodiment.

In some of these embodiments, the first device and the second device exchange device information according to the communication channel, including:

As shown in fig. 4, as the first device and the second device to be networked, both the discovered end and the discovered end are in the networking process. Discovery may be achieved or discovered in different ways when networking is performed over different communication channels.

The operation of the device as a discovery terminal will be further described.

the local machine sends a control request to the connected peripheral USB equipment through an AOA protocol;

If the USB channel is accessed, specifically, a USB interface is inserted, the host enters host mode, and sends a control request to the connected peripheral USB device through the AOA protocol, so as to determine whether the peripheral USB device supports the Android Accessory protocol.

If the peripheral USB equipment supports the protocol, a non-zero number can be returned to represent the protocol version supported by the peripheral USB equipment, connection is opened, access manufacturer information is obtained, port information is read and written, local information is sent, and a USB Host channel between the local and the peripheral USB equipment is established.

If the peripheral USB device does not support the protocol, returning to zero, and entering an Access (slave) mode by the peripheral USB device.

under the condition that the peripheral equipment is CoAP WIFI equipment, local information is sent to the peripheral equipment, and a CoAP channel of the WIFI is established;

In this embodiment, if the device is used as a hotspot, UDP multicast is started, a server is established, and a discovery information protocol is sent. Multicast refers to a one-to-many transmission scheme, where a transmitting end transmits data into one group. The local machine is in a multicast mode, and can efficiently send as many packets as possible to different, possibly even unknown devices.

If the local machine is not used as a hot spot, starting UDP broadcasting, establishing a server and sending a discovery information protocol. Here, broadcasting refers to a communication mode of "one-to-all" between hosts, and a broadcaster can send information to all devices in a network.

If the local receives the receipt of the UDP transmission discovery protocol, the client is established, the local information is transmitted, and UDP and TCP channels of the WIFI are established.

If the local is low-power-consumption equipment, a CoAP protocol client is built, a CoAP protocol server is connected, local information is sent, and a WIFI CoAP channel is built.

CoAP is established on the UDP protocol, and a binary encapsulation protocol packet is adopted, so that the CoAP simulates the HTTP protocol (Hyper Text Transfer Protocol ) in terms of user visibility, and is beneficial to use, and the connection establishment method is the same as UDP, a server is established through an IP address and a port, and a client is connected with the server through the port to establish connection.

If the host can be searched, the host can obtain the Bluetooth name of the host, manufacturer data and service UUID, and an information read-write Bluetooth Gatt channel is established.

The local machine can start the client of the SPP protocol according to the searched Bluetooth name, connect with the server, send the local information and establish the Bluetooth SPP channel, and can be understood that the server does not actively disconnect, waits for other clients to connect, and the client actively searches for the server and establishes connection with the server.

If the host is not searched by the host, a Gatt protocol host end is established, advertisement information including Bluetooth names, manufacturer data and service UUIDs is sent, the slave is waited for searching, and specifically, a server end of an SPP protocol can be started, and the client is waited for searching.

The local device receives a discovery information protocol if it is a discovered terminal, and typically, the discovery information protocol is sent in a broadcast information manner to indicate the characteristics of the device itself, so that other similar devices can find the discovered terminal based on the broadcast information and start a discovery service.

If the local machine is a USB device and a USB interface is inserted, the local machine enters an Access mode.

Specifically, if the local machine receives a control request sent by the USB device connected with the AOA protocol, the receipt sends the supported protocol version, confirms the connection, sends the information of the Access manufacturer, reads and writes the port information, establishes a USB Access channel, and receives the discovery information.

And if the local machine does not receive the USB equipment (equipment connected with the USB line) connected with the AOA protocol, sending a control request, and entering a Host mode.

The process is similar to the working process that the local USB device is used as the discovery end, and the description is omitted here.

If the local machine is the WIFI equipment with the WIFI module, a network server is established and information is ready to be received. If the local receives the information of the UDP transmission discovery protocol, the receipt transmits the local information, establishes a client, and establishes UDP and TCP channels of the WIFI.

If the local is a low-power-consumption device, a CoAP protocol client is built, a CoAP protocol server is connected, local information is sent, and a WIFI CoAP channel is built.

If the local machine is a Bluetooth device with a Bluetooth module, the local machine can establish a Gatt protocol host end.

Next, the local machine issues advertisement information including information of bluetooth name, vendor data, service UUID, etc. to wait for the slave machine to search. Specifically, a server of the SPP protocol may be started, waiting for a client to search; the local machine can update the local machine and the information in the group according to the received information and the condition of establishing the channel.

It should be understood that, in this embodiment, the local device, the slave device, the host device, and the peripheral device may refer to devices that need to be added to the device group, such as the first device and the second device, to implement automatic networking, and when implementing, the first device and the second device may be added to the device group in different manners, such as the host device, the slave device, and the peripheral device, so as to improve the networking efficiency.

Step 103: the first device and the second device establish a device group according to the exchanged device information.

In this embodiment, the networking core of each device starts a channel service, issues local information, acquires peripheral device information from different channels, merges the local information and the peripheral information, updates built intra-group information of the device group according to channel state changes, shares the intra-group information, and completes the construction of the distributed framework.

After connection is established based on the communication channel, each device can add channel information into shared intra-group information, when the name of the communication channel changes or the connection state changes, the changed information can be updated to the latest state to correct old information in the device group, so that the intra-group devices form a virtual group, the intra-group information is shared, and the establishment of the distributed framework is completed.

In implementation, one or more communication channels may be used as needed, for example, if the first device supports a WIFI channel and a USB channel, and the second device supports a WIFI channel and a bluetooth channel, data transmission may be implemented only through the WIFI channel; if the first equipment and the second equipment both support the WIFI channel and the USB channel, data transmission can be performed through the WIFI channel and the USB channel at the same time, and the integrity of the data channel is guaranteed.

As shown in fig. 3, each device can complete the establishment of a device group and complete the fusion of multi-channel information, in this embodiment, the fusion of multi-channel information refers to that the response piece information acquired by UDP broadcast, gatt advertisement information and USB control command are all different, but are all networking information, and are uniformly converted into networking information, and the networking information is fused in an information management module, including different communication protocols and different transmission channels, but the fusion of protocol packets of a formulated standard is then sent.

Step 104: the first device and the second device exchange data information in the device group.

After the networking convergence is completed, the first device and the second device can exchange data information such as files, information, stream communication and the like.

In this embodiment, the first device and the second device may perform direct transmission of information, that is, realize transmission of data such as a file and information through a certain communication channel therein.

In some embodiments, if the size of the file to be transmitted is larger, the transmission efficiency may be improved by parallel transmission.

As shown in fig. 5, in this embodiment, the first device and the second device have completed networking and have WIFI, bluetooth, and USB channels.

When the method is implemented, the first device reads the file stream, reads the first data block of the data with the Buf1 size and sends the data through the USB channel, reads the second data block with the Buf2 size and sends the data through the WIFI channel, reads the third data block with the Buf3 size and sends the data through the Bluetooth channel, and all the data channels send the corresponding data blocks to the second device in parallel.

The second device receives the first data block with the Buf1 size through the USB channel, the second data block with the Buf2 size through the WIFI channel, the third data block with the Buf3 size through the Bluetooth channel, and the second device creates a file stream and writes data.

And then, the first equipment and the second equipment circularly process according to the process, namely, the first equipment continuously reads the first data block through the USB channel and sends the first data block to the second equipment, the second data block is continuously read through the WIFI channel and sent to the second equipment, the third data block is continuously read through the Bluetooth channel and sent to the second equipment, and the second equipment continuously circularly writes until the file transmission is completed.

In this way, by simultaneously performing data transmission using a plurality of communication channels, the data transmission speed can be increased.

In another embodiment, the corresponding communication channel is selected for data transmission according to the data type.

As shown in fig. 6, in an exemplary embodiment, the first device reads the file stream, and the first data block with the read Buf size is sent to the second device through the USB channel, and the read message data is sent to the second device through the WIFI channel, and the read command data is sent to the second device through the bluetooth channel, where the above sending processes are also performed in parallel. The second device receives the data through the corresponding communication channel and then executes corresponding processing outflow.

As shown in fig. 7, in some embodiments, the two modes may be combined with each other, i.e. data transmission, command execution, message splitting may be performed using different types of communication channels and parallel channels as needed, which are not further defined and described herein.

In some of these embodiments, in the case where the number of devices is plural, and where there is no direct communication channel between two devices, data transfer between the two devices may be achieved by way of transfer.

In some of these embodiments, the communication system further comprises a third device communicatively coupled to the first device;

As shown in fig. 8A and 8B, in this embodiment, the first device is a tablet computer, the second device is a large-sized integrated machine, the third device is a mobile phone, and the three devices are already networked, where the large-sized integrated machine device and the tablet computer have established USB connection, and the mobile phone and the tablet computer have established WIFI or bluetooth connection.

If the mobile phone is expected to send information to the large-size integrated machine, the mobile phone connection information is searched for the channel information of the large-size integrated machine, and if the available through channel information is obtained, the equipment and the channel can be switched by referring to the mode, and the information is sent.

In this embodiment, the mobile phone and the large-sized integrated machine are not directly connected through the communication channel, that is, no available through channel information is obtained, so that a transit channel search is performed, and a heterogeneous communication flow is started.

Specifically, in this embodiment, WIFI and bluetooth channels are searched in the channel information of the mobile phone, the connection device is a tablet computer, and a USB channel exists between the tablet computer and the large-size integrated machine is searched in the group information.

The mobile phone sends target data information to be transferred, including the name and the channel type of the initial equipment and the name and the channel type of the target equipment to the tablet personal computer. When the scheduling management module is automatically selected by the system, the initial equipment name and the channel type can be processed by equipment allocation and channel switching according to equipment conditions and channel conditions, and the destination equipment name and the channel type can be given to the tablet personal computer. In one embodiment, the format of the initiator information carried by the target data information is { initiator name: cell phone, channel type: WIFI }, the format of the carried destination device information is { destination device name: large-size all-in-one, channel type: USB }.

In some of these embodiments, in order to ensure reliability and stability of data transmission when the target data information is streamed between different devices, a generic data transmission protocol may be set.

In one embodiment of the invention, the data transfer protocol is defined in the following manner.

And the local equipment encapsulates the original data into transmission data according to a certain protocol rule, transmits the transmission data to other equipment through a networking channel, receives the transmission data by the other equipment, and unpacks the transmission data according to the protocol rule to obtain the original data.

As shown in fig. 9, in this embodiment, the definition and composition of the overall protocol packet are as follows:

the initiator (2 bytes) uses 0x7b 0x5b as the initiator of the protocol packet, i.e., "{ [".

Packet length (2 bytes), packet length = initiator occupied byte + packet length occupied byte + message type occupied byte + data length occupied byte + data stream number occupied byte + data occupied byte + check code occupied byte + terminator occupied byte.

Through the packet length, the broken packets and the sticky packets can be effectively processed, and the integrity of data is ensured. The received data length is longer than the packet length, which indicates that the data packet is incomplete, the broken packet is needed to be spliced after the next reading, the received data length is longer than the packet length, which indicates that the data packet is sticky, and after the actual data is read, the rest part is cached to wait for the next splicing.

Message type (2 bytes) including 0x01 message, 0x02 file, 0x03 command.

Data type (2 bytes) including 0x01 text, 0x02 binary, 0x03 json.

Data length (2 bytes), data length=data type occupied byte+data length occupied byte+data stream number occupied byte+data occupied byte.

And the number of the data stream (2 bytes), the accumulated integer number, and no packet re-package and packet loss are ensured.

The data (dynamic bytes) are different in packet format, and the multi-packet and single-packet are different according to the type of data.
