Referring to fig. 2, fig. 2 is a schematic flow chart of a data transmission method provided in an embodiment of the present application, and the data transmission method is applied to an electronic device, where the electronic device includes a wireless transceiver module, and as shown in the figure, the data transmission method includes:
s201, an electronic device obtains at least one data transmission task that needs to be sent to a target node, where the target node is a device in a first local area network to which the electronic device accesses through the wireless transceiver module, and the first local area network includes the electronic device, the target node, and at least one relay device;
wherein the at least one data transmission task is one or more data types. The wireless transceiver module includes, but is not limited to, a LORA module.
S202, when detecting that a first transmission link cannot meet a transmission requirement of the at least one data transmission task, the electronic device obtains link information of at least one relay link and each relay link in the first local area network, where the first transmission link is a direct connection communication link between the electronic device and the target node;
the link information is a link information parameter capable of reflecting the load transmission capability of each relay link. The direct communication link cannot meet the transmission requirement, and may be limited in transmission distance or poor in quality of the transmission link.
S203, the electronic equipment selects a plurality of relay links for transmitting the at least one data transmission task according to the at least one data transmission task and the link information of each relay link;

S204, the electronic equipment transmits the at least one data transmission task through the plurality of relay links.
In a specific implementation, the transmission of the at least one data transmission task may be a single transmission or multiple repeated transmissions according to the selected relay link.
It can be seen that, in this embodiment of the present application, an electronic device obtains at least one data transmission task that needs to be sent to a target node, where the target node is a device in a first local area network that the electronic device accesses through the wireless transceiver module, and the first local area network includes the electronic device, the target node, and at least one relay device; when detecting that a first transmission link cannot meet the transmission requirement of the at least one data transmission task, acquiring link information of at least one relay link and each relay link in the first local area network, wherein the first transmission link is a direct connection communication link between the electronic device and the target node; selecting a plurality of relay links for transmitting the at least one data transmission task according to the at least one data transmission task and the link information of each relay link; transmitting the at least one data transmission task over the plurality of relay links. Therefore, the electronic equipment can acquire the plurality of relay links according to the condition that the direct connection communication link does not meet the transmission requirement, and select the relay link for transmission according to the link information of the plurality of relay links and the data transmission task to be transmitted, so that the success rate and the stability of data transmission are improved.

The bandwidth (band width) refers to the amount of data that can be transmitted in a fixed time, i.e. the capacity of transmitting data in the transmission pipeline. The Data rate is the Data transfer rate. In the spread spectrum system, the bandwidth is increased as the spreading factor is increased, but the data rate may be decreased instead of being increased in the LoRa modulation. The packet loss rate is a ratio of the number of lost data packets in the test to the number of transmitted data packets, and generally, the higher the data rate is, the larger the packet loss rate is. The delay refers to the time from data transmission to reception and successful processing.
The at least one data transmission task may include transmission data and preset parameters, where the preset parameters may be parameters such as transmission requirements of the transmission data. When the preset parameter is a data type, acquiring the data rate of each relay link; when the preset parameter is the data volume, acquiring the data rate or the current bandwidth of each relay link; when the preset parameter is data importance, acquiring the packet loss rate of each relay link; and when the preset parameter is a real-time requirement, acquiring the time delay of each relay link. The link information of each relay link may be acquired as one link information or multiple link information, for example, when the preset parameter is a data amount and a real-time requirement, the data rate and the time delay of each relay link are acquired.

As can be seen, in this example, the electronic device can obtain the link information corresponding to each relay link based on the preset parameter of the at least one data transmission task that needs to be sent, so that the time for obtaining and processing the link information is saved, and the data transmission rate is improved.
In one possible example, the selecting, according to the at least one data transmission task and the link information of each relay link, a plurality of relay links for transmitting the at least one data transmission task includes: performing priority sequencing on each relay link according to the at least one link information to obtain a first priority sequence corresponding to the at least one link information; grouping and sequencing the at least one data transmission task according to the at least one link information to obtain a first data transmission task group; and selecting a plurality of relay links for transmitting the at least one data transmission task according to the first priority sequence and the first data transmission task group.
And comparing at least one link information of each relay link, wherein the link information comprises current bandwidth, data rate, time delay, packet loss rate and the like, so as to obtain the link transmission capability of each relay link, and sequencing each relay link from good to bad according to the link transmission capability.
In a specific implementation, when the link information is the current bandwidth, comparing the bandwidth information from each relay device to a target node, and sorting the bandwidth information from large to small according to the current bandwidth, wherein if the current bandwidth is larger and the priority is higher, the priority sequence of the relay link corresponding to the current bandwidth is relay a-terminal B, relay B-terminal B, relay c-terminal B and the like in sequence; grouping the at least one data transmission task according to the data importance according to the current bandwidth to obtain a first data transmission task group with data importance of data 1, data 2, data 3 and the like from high to low; the plurality of relay links for transmission are selected according to relay a-terminal B, relay B-terminal B, relay c-terminal B, etc., and data 1, data 2, data 3, etc. Specifically, the data transmission tasks may be classified according to characteristics of a communication system, for example, in a lora modulation system, the wider the bandwidth is, the higher the reliability is, and the at least one data transmission task may be classified into data 1, data 2, data 3, and the like according to data importance; in a common FSK modulation system, the wider the bandwidth is, the higher the data rate is, and the at least one data transmission task can be divided into data 1, data 2, data 3 and the like from large to small according to the size of data volume; the multiple relay links for transmission are then selected based on relay a-terminal B, relay B-terminal B, relay c-terminal B, etc., as well as data 1, data 2, data 3, etc.
When the link information is the data rate, comparing the data rate information from each relay device to the target node, and sequencing the data rates from large to small, wherein the higher the data rate is, the higher the priority is, the priority sequence of the relay link corresponding to the data rate is relay a-terminal B, relay B-terminal B, relay c-terminal B and the like in sequence; and grouping the at least one data transmission task according to the data volume according to the data rate information to obtain a data transmission task group with the data volume from large to small of data 1, data 2, data 3 and the like, and then selecting a plurality of relay links for transmission according to the relay a-terminal B, the relay B-terminal B, the relay c-terminal B and the like, the data 1, the data 2, the data 3 and the like.
When the link information is the packet loss rate, comparing the packet loss rate information from each relay device to the target node, and sorting the packet loss rates from small to large, wherein the smaller the packet loss rate is, the higher the priority is, and the link priority sequences corresponding to the packet loss rate are relay a-terminal B, relay B-terminal B, relay c-terminal B and the like in sequence; and grouping the at least one data transmission task according to the data importance according to the packet loss rate to obtain a data transmission task group with the data importance from large to small of data 1, data 2, data 3 and the like, and then selecting a plurality of relay links for transmission according to the relay a-terminal B, the relay B-terminal B, the relay c-terminal B and the like, the data 1, the data 2, the data 3 and the like.
And the link information is time delay, the time delay information from each relay device to the target node is compared, the time delay is sequenced from small to large, the smaller the time delay is, the higher the priority is, and the link priority sequence corresponding to the time delay is relay a-terminal B, relay B-terminal B, relay c-terminal B and the like in sequence. And grouping the at least one data transmission task according to the time delay and the real-time requirement to obtain a data transmission task group with the real-time requirement from large to small of data 1, data 2, data 3 and the like, and then selecting a plurality of relay links for transmission according to the relay a-terminal B, the relay B-terminal B, the relay c-terminal B and the like, the data 1, the data 2, the data 3 and the like.
In a specific implementation, the link information is a combination of multiple link information, for example, the link information may be a time delay and a packet loss rate, a data rate and a time delay, or a packet loss rate and a time delay. And when the link information is time delay and packet loss rate, grouping the at least one data transmission task according to the data importance and real-time requirements by the at least one data transmission task according to the data importance and real-time requirements, and selecting a relay link for transmission according to the link priority sequence and the grouping.
As can be seen, in this example, since the electronic device can perform priority ordering of the relay links and group the at least one data transmission task based on the link information, and then select multiple relay links for transmitting the at least one data transmission task according to the priority ordering and the grouping, accurate transmission of data is ensured, and success rate and stability of data transmission are improved.
In one possible example, the selecting, according to the at least one data transmission task and the link information of each relay link, a plurality of relay links for transmitting the at least one data transmission task includes: performing priority sequencing on each relay link according to the at least one link information to obtain a second priority sequence corresponding to the at least one link information; grouping and sequencing the at least one data transmission task according to the second priority sequence and the data volume of the at least one data transmission task to obtain a second data transmission task group with the data volume from large to small; time stamping the second data transmission task packets and link stamping the second data transmission task packets according to the second priority sequence; selecting a plurality of relay links for transmitting the at least one data transmission task according to the time stamp and the link label.
In a specific implementation, when the link information is a data rate, the data rates from the relay devices to the target node are compared, and the data rates are sorted from large to small, for example, a relay a-terminal B, a relay B-terminal B, a relay c-terminal B, and the like are sequentially performed. Classifying at least one data transmission task to be transmitted, stamping a time stamp, for example, classifying the data transmission task into data 1, data 2, data 3 and the like, wherein the data amount of the data 1 is more than or equal to that of the data 2 is more than or equal to that of the data 3, marking the data 1 with a link mark of a relay a-terminal B, marking the data 2 with a link mark of a relay B-terminal B, marking the data 3 with a link mark of a relay c-terminal B and the like, then transmitting the data 1 according to a relay link of the relay a-terminal B, transmitting the data 2 according to the relay link of the relay B-terminal B, transmitting the data 3 according to the relay link of the relay c-terminal B and the like. For example, in a point-to-point LORA connection scenario between a device a and a target node B, the device a initiates a video call request, the AB determines that the current video function needs to transmit data through a relay link based on a position relationship, and the like, the device a acquires the relay link, and when data rates of multiple relay links are insufficient, that is, data transmission cannot be supported through a certain relay link, the device a groups video stream data packets, stamps link marks and timestamps, and performs packet transmission and aggregation reassembly through different relay links. The grouping of video stream data packets includes, but is not limited to, an equal proportion distribution according to the link bandwidth.
The link information may further include a time delay and the like. Sorting according to time delay from small to large, for example, sequentially sorting at least one data transmission task to be transmitted for a relay a-terminal B, a relay B-terminal B, a relay c-terminal B and the like, and stamping a timestamp, for example, dividing the data transmission task into data 1, data 2, data 3 and the like, wherein the data quantity of the data 1 is more than or equal to the data quantity of the data 2 and more than or equal to the data quantity of the data 3, marking the data 1 with a link label of the relay a-terminal B, marking the data 2 with a link label of the relay B-terminal B, marking the data 3 with a link label of the relay c-terminal B and the like, then transmitting the data 1 according to a relay link of the relay a-terminal B, transmitting the data 2 according to a relay link of the relay B-terminal B, transmitting the data 3 according to a relay link of the relay c-terminal B and the like.
As can be seen, in this example, the electronic device may group the at least one data transmission task according to the link information, mark the group with a link label and a timestamp, and transmit the corresponding data group according to the relay link corresponding to the link label, thereby improving reliability and stability of data transmission.
In one possible example, the performing packet ordering on the at least one data transmission task according to the at least one link information to obtain a first data transmission task packet includes: acquiring a preset grouping condition corresponding to the at least one data transmission task according to the at least one link information, wherein the preset grouping condition comprises a grouping number and a grouping type; and performing grouping sequencing on the at least one data transmission task according to the preset grouping condition to obtain a first data transmission task group.
The corresponding relationship between the link information and the preset packet type includes that when the link information is the current bandwidth, the packet type is data importance or data volume, when the link information is the data rate, the packet type is data type or data volume, when the link information is the packet loss rate, the packet type is data importance, and when the link information is time delay, the packet type is the data real-time requirement. The packet number may be grouped according to the link priority sequence, for example, the packet number may be divided into 4 corresponding groups of first data transmission task packets according to 4 link data with a high priority of the link priority; several relay links meeting the transmission requirements can be selected to group data, and at least one data transmission task can be grouped according to each relay link.
In one possible example, the transmitting the at least one data transmission task over the plurality of relay links includes: and sequentially transmitting the plurality of data transmission task packets through a plurality of relay links from high priority to low priority in the priority sequence.
In a specific implementation, the multiple data transmission task packets are sequentially transmitted through the relay link with higher priority, for example, the priority in the first sequence is sequentially from high to low, namely relay a-terminal B, relay B-terminal B, relay c-terminal B, and the like, and the data importance of the first data transmission task packet is data 1, data 2, data 3, and the like from high to low; data 1 is transmitted over the relay link of relay a-terminal B, data 2 is transmitted over the relay link of relay B-terminal B, and data 3 is transmitted over the relay link of relay c-terminal B.
In one possible example, the transmitting the at least one data transmission task over the plurality of relay links includes: and when each relay link does not meet the transmission requirement, transmitting each data transmission task group through the plurality of relay links.
And when the transmission condition of each relay link is not good, each data transmission task group of the at least one data transmission task is sequentially sent through a plurality of relay links.
In a specific implementation, when it is detected that the transmission condition of each relay link is relatively poor, for example, when the current bandwidth is smaller than the preset bandwidth, priority ordering can be performed according to the link information from each current relay terminal to the target node B, for example, the link condition is relay a-terminal B, relay B-terminal B, relay c-terminal and the like in sequence from good to bad, the data transmission task packet data 1 is transmitted according to the relay a-terminal B, the relay B-terminal B, the relay c-terminal B and the like, the data 2 is transmitted … … according to the relay a-terminal B, the relay B-terminal B, the relay c-terminal B and the like, after the target node receives the data, and comparing the received data, discarding the same data, and recovering the data into the data of the at least one data transmission task.
