As shown in fig. 3, in an embodiment, when it is detected that the transmission index does not meet the criterion, a specific implementation manner of selecting an adaptive transmission channel from a plurality of standby transmission channels based on a preset adaptation model includes:
step S302, when the first QoS is smaller than the quality threshold value, the transmission index is determined not to reach the standard, and the second QoS of the standby transmission channels is calculated based on a preset adaptive model.
The second QoS may be calculated with reference to the first QoS.
Step S304, sorting the second QoS of the plurality of standby transmission channels based on a preset adaptation model, and determining an adaptation transmission channel based on a sorting result.
In the embodiment, based on a preset adaptation model, second QoS detection of a plurality of standby transmission channels is realized, the standby transmission channels are sequenced based on the second QoS of each standby transmission channel, the standby transmission channels of the second QoS are determined as adaptation transmission channels, so that selection of the transmission channel with the optimal transmission quality in a multilink is realized, the adaptation transmission channel is adopted to replace an initial transmission channel to transmit a message to be transmitted, and reliable communication and management of data between an internet of things node and an internet of things application platform are realized.
In an embodiment, in step S106, the matching and adjusting the transmission parameter of the packet to be transmitted based on the channel characteristic of the adaptive transmission channel specifically includes:

As shown in fig. 4, in an embodiment, specifically, the adjusting at least one of a sequence, a code length, and a code rate of the message to be transmitted based on the channel characteristic of the adaptive transmission channel to generate a specific implementation manner of the adjustment result includes:
step S402, determining the corresponding code rate and code length based on the channel characteristics.
And step S404, determining a corresponding base map according to the code rate and the code length.
Step S406, determines the corresponding maximum code block bit number based on the base map.
Step S408, adding CRC attachment to the message to be transmitted.
Step S410, when the message to be transmitted added with the CRC attachment is detected to be larger than the maximum code block bit number, the message to be transmitted is segmented to obtain segmented code blocks.
Step S412, when it is detected that the to-be-transmitted message with CRC attachment added is less than or equal to the maximum code block bit number, the to-be-transmitted message with CRC attachment added is used as a code block to be encoded.
Step S414, add CRC attachment to the segmented code block, and use the segmented code block with CRC attachment as the code block to be encoded.
Step S416, low-density parity check (LDPC) coding is carried out on the code block to be coded to obtain a coded code block, and the coded code block is used as a regulation result.

Further, in one embodiment, a specific implementation of performing rate matching and/or hybrid automatic repeat request HARQ based on the adjustment result includes:
step S418, perform rate matching, HARQ processing, and interleaving on the encoded code block to obtain an adjusted message to be transmitted.
Specifically, taking NR data channel as an example, after determining a corresponding code rate and a corresponding code length based on channel characteristics, one of 2 Base Graphs (BG) is selected according to the code rate and the code length to perform LDPC encoding, where the size of BG1 is 46x68, the lowest supported code rate is 1/3, and the size of BG2 is 42x 52.
After the physical layer of the industrial gateway receives a transport block of the medium access control layer (MAC), it is added with a (16 or 24 bit) CRC. After the CRC is added, if the number of bits included in the CRC exceeds a certain value, the CRC needs to be divided into two or more code blocks having the same length, and the whole certain value is the maximum code block amount Kcb.
The principle of code block segmentation is that when BG1 is used, the largest code block Kcb is 8448, and when BG2 is used, Kcb is 3840. After LDPC coding, Rate Matching (RM) is performed for each code block bit stream. Bit selection is performed first, and then bit interleaving is performed to form a redundancy version number (RV), that is, each coded code block is subjected to rate matching, hybrid automatic repeat request (HARQ) processing, and interleaving, respectively.

Step S510, if the first transmission quality QoS does not meet the standard, the gateway triggers the enabling discovery module to select a transmission channel with the best transmission quality in the backup multilink.
And S512, the data is retransmitted after redesigning according to the selected channel characteristics, wherein the redesign comprises a sequence, a code length, a code rate, a rate matching, an HARQ and the like.
And step S514, the application platform receives and processes the data with the shortest transmission time delay and the highest reliability.
Step S516, judging whether communication and management such as mutual translation conversion, display, storage and control of different protocols of various terminal node data in the 5G Internet of things exit, if yes, entering step S518, if no, returning to step S506.
And S518, closing various terminal node devices and interfaces in the 5G Internet of things, and finishing the work of the multilink backup high-reliability industrial gateway.
