Please refer to FIG. 2. FIG. 2 is a schematic flowchart of a data transmission method provided by an embodiment of the present application, which is applied to an electronic device. The electronic device includes a wireless transceiver module. As shown in the figure, the data transmission method includes:

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 the first transmission link cannot meet the transmission requirement of the at least one data transmission task, the electronic device acquires at least one relay link and each relay link in the first local area network The link information, the first transmission link is a direct communication link between the electronic device and the target node;

The link information is a link information parameter that can reflect the load transmission capability of each relay link. The directly connected communication link cannot meet the transmission requirements, which may be due to limited transmission distance or poor quality of the transmission link.

S203, the electronic device selects, according to the at least one data transmission task and the link information of each relay link, multiple relay links for transmitting the at least one data transmission task;

The electronic device can divide the data to be transmitted according to the bandwidth load capacity of each relay link, or multiplex multiple relay links for concurrent transmission of the same data, or group the transmitted data and mark the Link tag and time stamp, and then select the link corresponding to the link tag for transmission.

S204, the electronic device transmits the at least one data transmission task through the multiple 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, etc. according to the selected relay link.

It can be seen that, in this embodiment of the present application, the electronic device acquires at least one data transmission task that needs to be sent to a target node, and the target node is a device in the first local area network to which the electronic device accesses through the wireless transceiver module , the first local area network includes the electronic device, the target node and at least one relay device; when it is detected that the first transmission link cannot meet the transmission requirement of the at least one data transmission task, obtain the first At least one relay link in a local area network and link information of each relay link, the first transmission link is a direct communication link between the electronic device and the target node; according to For the at least one data transmission task and the link information of each relay link, select multiple relay links for transmitting the at least one data transmission task; and transmit the data through the multiple relay links the at least one data transfer task. It can be seen that the electronic device can obtain multiple relay links when the direct communication link does not meet the transmission requirements, and select the medium for transmission according to the link information of the multiple relay links and the data transmission task to be transmitted. Following the link, the success rate and stability of data transmission are improved.

The bandwidth is also called bandwidth, which refers to the amount of data that can be transmitted at a fixed time, that is, the ability to transmit data in a transmission pipeline. The data rate is the data transfer rate. In a system with spread spectrum, the larger the spreading factor, the larger the bandwidth, but in LoRa modulation, the data rate is not higher, but may become lower. The packet loss rate refers to the ratio of the number of lost data packets to the transmitted data packets in the test. Generally speaking, the higher the data rate, the greater the packet loss rate. The latency 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, and the preset parameters may be parameters such as transmission requirements of the transmission data. When the preset parameter is the data type, obtain the data rate of each relay link; when the preset parameter is the data amount, obtain the data rate or current bandwidth of each relay link ; When the preset parameter is data importance, obtain the packet loss rate of each relay link; when the preset parameter is a real-time requirement, obtain the time of each relay link extension. The link information obtained for each relay link may be one type of link information or multiple types of link information. For example, when the preset parameters are data volume and real-time requirements, obtain the link information. data rate and delay of each trunk link.

In the specific implementation, the electronic device obtains the relay link information corresponding to the preset parameters, and can also query the link information that has been obtained the most times in history when the user has no preset parameters for the data transmission task, that is, when there are no parameters such as transmission requirements. Acquire; acquire link information according to the acquisition strategy preset by the user. The preset acquisition strategy can be to acquire one kind of link information, or a combination of multiple link information, such as acquiring each relay link All link information, and then compare and process all link information.

It can be seen that in this example, the electronic device can obtain the link information corresponding to each relay link based on the preset parameters of at least one data transmission task to be sent, which saves the time for obtaining and processing link information and improves the efficiency of data transmission. rate.

In a possible example, selecting multiple 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, The method includes: prioritizing each relay link according to the at least one type of link information to obtain a first priority sequence corresponding to the at least one type of link information; The information performs grouping sorting on the at least one data transmission task to obtain a first data transmission task group; according to the first priority sequence and the first data transmission task grouping, a Multiple trunk links.

Wherein, at least one link information of each relay link is compared, and the link information includes current bandwidth, data rate, delay, packet loss rate, etc., to obtain the link transmission of each relay link Each relay link is ranked from good to bad according to the link transmission capacity.

In the specific implementation, when the link information is the current bandwidth, the bandwidth information from each relay device to the target node is compared, and the current bandwidth is sorted in descending order. The priority sequence of the relay link is relay a-terminal B, relay b-terminal B, relay c-terminal B, etc.; according to the current bandwidth, the at least one data transmission task is grouped according to data importance, Obtain the first data transmission task grouping of data 1, data 2, data 3, etc. from high to low data importance; according to relay a-terminal B, relay b-terminal B, relay c-terminal B, etc. and data 1. Data 2, Data 3, etc. select multiple relay links for transmission. Specifically, it can also be classified according to the characteristics of the communication system. For example, in a Lora-modulated system, the wider the bandwidth, the higher the reliability. The at least one data transmission task can be classified into data 1, Data 2, Data 3, etc.; in a common FSK modulation system, the wider the bandwidth, the higher the data rate, and the at least one data transmission task can be divided into data 1, data 2, and data 3 from large to small according to the amount of data. etc.; then multiple 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.

When the link information is the data rate, compare the data rate information from each relay device to the target node, and sort them in descending order of the data rate. The priority sequence of the route is relay a-terminal B, relay b-terminal B, relay c-terminal B, etc.; according to the data rate information, the at least one data transmission task is grouped according to the data volume to obtain the data volume The size is from large to small as data transmission task grouping of data 1, data 2, data 3, etc., and then according to relay a-terminal B, relay b-terminal B and relay c-terminal B, etc. and data 1, data 2 , Data3, etc. to select multiple relay links for transmission.

When the link information is the packet loss rate, compare the packet loss rate information from each relay device to the target node, and sort the packet loss rate from small to large. The smaller the packet loss rate, the higher the priority, and the corresponding packet loss rate. The link priority sequence is relay a-terminal B, relay b-terminal B, relay c-terminal B, etc.; according to the packet loss rate, the at least one data transmission task is grouped according to data importance, Obtain the data transmission task groupings of data importance from large to small as data 1, data 2, data 3, etc., and then according to relay a-terminal B, relay b-terminal B and relay c-terminal B, etc. and data 1 , Data 2, Data 3, etc. to select multiple relay links for transmission.

The link information is the time delay, compare the delay information from each relay device to the target node, and sort the delay from the smallest to the largest. Relay a-terminal B, relay b-terminal B, relay c-terminal B, etc. According to the delay, the at least one data transmission task is grouped according to the real-time requirements, and the data transmission task groups with the real-time requirements from large to small are data 1, data 2, data 3, etc., and then according to the relay a- Terminal B, relay b-terminal B, relay c-terminal B, etc., and data 1, data 2, data 3, etc., select multiple relay links for transmission.

In specific implementation, the link information is a combination of multiple types of link information, for example, the link information may be delay and packet loss rate, data rate and delay, or packet loss rate and delay. When the link information is delay and packet loss rate, the at least one data transmission task groups the at least one data transmission task according to the data importance and real-time requirements according to the data importance and real-time requirements. The link priority sequence and packet selects the relay link for transmission.

It can be seen that, in this example, since the electronic device can prioritize the relay links and group the at least one data transmission task based on the link information, and then select and transmit the at least one data transmission task according to the priority ordering and grouping. Multiple relay links for tasks ensure accurate data transmission and improve the success rate and stability of data transmission.

In a possible example, selecting multiple 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, The method includes: prioritizing each relay link according to the at least one type of link information to obtain a second priority sequence corresponding to the at least one type of link information; according to the second priority sequence grouping and sorting the at least one data transmission task with the data volume of the at least one data transmission task to obtain a second data transmission task grouping from large to small data volume; marking the second data transmission task grouping with a timestamp , and marking the second data transmission task grouping with a link mark according to the second priority sequence; selecting a plurality of links for transmitting the at least one data transmission task according to the time stamp and the link mark follow the link.

In the specific implementation, when the link information is the data rate, the data rates from each relay device to the target node are compared, and the data rates are sorted in descending order, for example, relay a-terminal B, relay b-terminal B. Relay c-terminal B, etc. At least one data transmission task to be sent is classified and time stamped, such as data 1, data 2, data 3, etc., where the data volume of data 1 ≥ the data volume of data 2 ≥ the data volume of data 3, the data 1 is marked with the link mark of relay a-terminal B, data 2 is marked with the link mark of relay b-terminal B, data 3 is marked with the link mark of relay c terminal B, etc., and then the data 1 is marked Send according to the relay link of relay a-terminal B, send data 2 according to the relay link of relay b-terminal B, send data 3 according to the relay link of relay c-terminal B Wait. For example, in the point-to-point LORA connection scenario between device A and target node B, device A initiates a video call request, AB determines that the current video function needs to transmit data through the relay link based on the location relationship, and device A obtains the relay link. The data rate of the relay link is insufficient, that is, the data transmission cannot be supported through a certain relay link, then the video stream data packets are grouped, marked with link marks and time stamps, and transmitted through different relay links respectively. and aggregate reorganization. The grouping of video stream data packets includes, but is not limited to, allocation in equal proportions according to link bandwidth.

Wherein, the link information may further include time delay and the like. Sort by delay from small to large, for example, relay a-terminal B, relay b-terminal B, relay c-terminal B, etc., at least one data transmission task to be sent is classified, and timestamped, such as For data 1, data 2, data 3, etc., where the data amount of data 1 ≥ the data amount of data 2 ≥ the data amount of data 3, mark data 1 on the link mark of relay a-terminal B, mark data 2 On the link label of relay b-terminal B, mark data 3 on the link label of relay c terminal B, etc., and then send data 1 according to the relay link of relay a-terminal B, and send data 2 It transmits by the relay link of relay b-terminal B, and transmits the data 3 by the relay link of relay c-terminal B, etc.

It can be seen that in this example, the electronic device can group the at least one data transmission task based on the link information, mark the packet with a link mark and a time stamp, and transmit the corresponding data packet according to the relay link corresponding to the link mark , which improves the reliability and stability of data transmission.

In a possible example, the performing grouping sorting on the at least one data transmission task according to the at least one type of link information to obtain a first data transmission task group includes: acquiring according to the at least one type of link information a preset grouping condition corresponding to the at least one data transmission task, where the preset grouping condition includes a number of groups and a grouping type; the at least one data transmission task is grouped and sorted according to the preset grouping condition to obtain the first data Transfer task groupings.

Wherein, the correspondence between the link information and the preset packet type includes: when the link information is the current bandwidth, the packet type is the data importance or the size of the data volume; when the link information is the data rate, the packet type is the data type or The size of the data volume. When the link information is the packet loss rate, the packet type is the data importance. When the link information is the time delay, the packet type is the data real-time requirement. The number of groups can be grouped according to the link priority sequence. For example, it can be divided into corresponding 4 groups of first data transmission task groups according to the data of the 4 links with high priority of the link priority; it is also possible to select the ones that meet the transmission requirements. Several relay links group data, and at least one data transmission task may also be grouped according to each relay link.

In a possible example, the transmitting the at least one data transmission task through the multiple relay links includes: passing through multiple relay links with descending priorities in the priority sequence The plurality of data transmission task packets are sequentially transmitted.

In a specific implementation, the multiple data transmission task packets are sequentially transmitted through a relay link with a higher priority. For example, in the first sequence, the priority from high to low is relay a-terminal B, relay b-terminal B. Relay c-terminal B, etc. The data importance of the first data transmission task grouping from high to low is data 1, data 2, data 3, etc.; For transmission, the data 2 is transmitted on the relay link of the relay b-terminal B, the data 3 is transmitted on the relay link of the relay c-terminal B, and the like.

In a possible example, the transmitting the at least one data transmission task through the multiple relay links includes: when each of the relay links does not meet the transmission requirement, transferring each data The transmission task packet is transmitted through the plurality of relay links.

Wherein, 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 sent sequentially through multiple relay links.

In the specific implementation, when it is detected that the transmission status of each relay link is relatively poor, for example, when the current bandwidth is less than the preset bandwidth, the priority can be determined according to the current link information from each relay terminal to the target node B. Sort, for example, the link conditions from good to bad are relay a-terminal B, relay b-terminal B, relay c-terminal, etc. The data transmission task is to be grouped into data 1 according to relay a-terminal B, middle Relay b-terminal B is sent, relay c-terminal B, etc. are sent, and data 2 is sent according to relay a-terminal B, relay b-terminal B, relay c-terminal B, etc... The target node After the data is received, a comparison process is performed on the received data, the same data is discarded, and the data is restored to the data of the at least one data transmission task.
