Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of tunnels and underground engineering, and particularly relates to a data interaction method based on adaptive redundant transmission. BACKGROUND

[0002] In the fields of industrial automation, process control, Internet of Things, etc., the reliability of wireless communication is crucial. Due to the complexity and variability of industrial environments (such as large metal equipment, motor interference, temperature changes), wireless channels often face severe fading, interference and multipath effects, leading to data transmission errors or interruptions.

[0003] To combat unstable channels, existing technologies usually employ multiple redundancy mechanisms to improve reliability. One common method is time redundancy, i.e., multiple retransmissions of the same data packet (ARQ mechanism), but this introduces unpredictable delays, which is not suitable for industrial control scenarios that require high real-time performance. Another method is frequency redundancy, such as frequency hopping spread spectrum (FHSS) or transmitting the same data packet simultaneously on multiple preset frequency bands. This "static redundancy" or "fixed redundancy" strategy, i.e., regardless of channel quality, uses a fixed number of frequency bands and transmission times.

[0004] However, the static redundancy method has significant shortcomings: resource waste: when the wireless channel quality is good, multiple frequency band, multiple times of redundant transmission will cause serious waste of spectrum resources and energy, especially for power-sensitive terminal devices; insufficient reliability: when the wireless environment deteriorates sharply, the quality of all preset frequency bands becomes poor, and the fixed number of redundancies may still be insufficient to ensure successful reception of data packets, leading to communication interruption; poor adaptability: the quality of wireless channels in industrial environments is dynamically changing, and static strategies cannot adjust according to real-time channel conditions, lacking flexibility and intelligence.

[0005] In addition, some adaptive technologies (such as adaptive modulation and coding AMC) mainly focus on adjusting data transmission rates and coding methods on a single channel, and cannot intelligently utilize multiple frequency band resources for redundant transmission. SUMMARY

[0047] It should be understood that the following embodiments are merely further elaborations on the present invention and not limitations thereof. Various modifications and variations can be made by those skilled in the art without departing from the spirit of the present invention, and all such modifications and variations should fall within the protection scope of the present invention.

[0048] The following is in conjunction with the appendix Figure 1 The following describes typical embodiments of the present invention and their specific steps.

[0049] As attached Figure 1 As shown, a data interaction method based on adaptive redundancy transmission includes:

[0050] S110. The frequency band used for data transmission between the data transmitter and the data receiver is taken as the target frequency band. The current quality information of the target frequency band is obtained through the data receiver. When the current quality information triggers the feedback condition, the data receiver is called to feed back the current quality information to the data transmitter through the target feedback channel according to the preset protection mechanism.

[0051] In one possible implementation, the method further includes:

[0052] When there are at least three nodes in the data interaction process, the data interaction process data is obtained, and the node roles are determined based on the data interaction process data. The node roles include data sender and data receiver.

[0053] When the target node in the data interaction process is the data sending end, a frequency band used for data transmission between the target node and the data receiving end corresponding to the target node is taken as a target frequency band, and the step of continuing to acquire current quality information of the target frequency band by the data receiving end and feeding back the current quality information to the data sending end through a target feedback channel according to a preset protection mechanism is continued.

[0054] When the target node in the data interaction process is the data receiving end, a frequency band used for data transmission between the data sending end corresponding to the target node and the target node is taken as a target frequency band, and the step of continuing to acquire current quality information of the target frequency band by the data receiving end and feeding back the current quality information to the data sending end through a target feedback channel according to a preset protection mechanism is continued.

[0055] For example, when there are at least three nodes in the data interaction process, such as a data transmission system in a master-slave architecture or a data transmission system in a peer-to-peer architecture, the same node plays different roles in different data transmission stages, that is, the node has the functions of the data sending end and the data receiving end.

[0056] S120, controlling the data sending end to generate a redundancy strategy for the current quality information according to a preset dynamic adjustment rule based on the current quality information, and controlling the data sending end to send data to the data receiving end according to the redundancy strategy, so as to complete data interaction.

[0057] By taking the frequency band used for data transmission between the data sending end and the data receiving end as the target frequency band, acquiring the current quality information of the target frequency band by the data receiving end, when the current quality information triggers a feedback condition, calling the data receiving end to feed back the current quality information to the data sending end through a target feedback channel according to a preset protection mechanism, controlling the data sending end to generate a redundancy strategy for the current quality information according to a preset dynamic adjustment rule based on the current quality information, and controlling the data sending end to send data to the data receiving end according to the redundancy strategy, so as to complete data interaction. By dynamically adjusting the redundancy strategy, unnecessary redundant transmission is reduced when the channel condition is good, the spectrum utilization rate is improved, and the device power consumption is reduced. At the same time, intelligent frequency band selection and redundancy number adjustment are adopted, and a higher transmission success rate can still be maintained in a poor channel environment. Through the special feedback channel protection and redundancy feedback mechanism, reliable transmission of control information is ensured.

[0058] In a possible implementation, the preset protection mechanism includes a first mechanism of feeding back in a frequency band with optimal channel quality, a second mechanism of redundantly sending the current quality information in at least two frequency bands, and a third mechanism of transmitting the current quality information by using a transmission scheme with a lower modulation order and a higher coding redundancy than a data channel; and the step of calling the data receiving end to feed back the current quality information to the data sending end through a target feedback channel according to the preset protection mechanism includes:

[0059] When the preset protection mechanism is the first mechanism of feeding back in a frequency band with optimal channel quality, the data receiving end is called to determine a frequency band with optimal channel quality in the target frequency band according to the current quality information, and the frequency band with optimal channel quality in the target frequency band is taken as the target feedback channel to feed back the current quality information to the data sending end through the target feedback channel.

[0060] When the preset protection mechanism is the second mechanism of redundantly sending the current quality information in at least two frequency bands, the data receiving end is called to filter out a candidate frequency band set satisfying a preset transmission condition in the target frequency band according to the current quality information, randomly select at least two frequency bands in the candidate frequency band set, and take the selected frequency bands as the target feedback channels to feed back the current quality information to the data sending end through the target feedback channels.

[0061] When the preset protection mechanism is the third mechanism of transmitting the current quality information by using a transmission scheme with a lower modulation order and a higher coding redundancy than a data channel, the data receiving end is called to obtain a target data channel modulation order when the data sending end and the data receiving end perform data transmission and a target coding redundancy when the data sending end and the data receiving end perform data transmission, and formulate a target transmission scheme according to the target data channel modulation order and the target coding redundancy, the target transmission scheme being lower than the data channel modulation order and higher than the coding redundancy.

[0062] A target feedback channel is determined in the target frequency band according to the target transmission scheme to feed back the current quality information to the data sending end through the target feedback channel.

[0063] For example, the feedback channel uses one of the following protection mechanisms: selecting a frequency band with optimal current channel quality as a dedicated feedback channel; redundantly sending the channel state report in multiple frequency bands; and using a transmission scheme with a lower modulation order and a higher coding redundancy than a data channel.

[0064] In a possible implementation, the step of controlling the data sending end to generate the redundancy strategy for the current quality information according to the current quality information and the preset dynamic adjustment rule comprises:

[0065] controlling the data sending end to classify the target frequency bands according to the current quality information and the preset dynamic adjustment rule, to obtain a first type of frequency band with channel quality greater than or equal to a first boundary value, a second type of frequency band with channel quality greater than or equal to a second boundary value and less than the first boundary value, and a third type of frequency band with channel quality less than the second boundary value;

[0066] controlling the data sending end to set a first target redundancy number for the first type of frequency band according to the current quality information of the first type of frequency band and the preset dynamic adjustment rule;

[0067] controlling the data sending end to set a second target redundancy number for the second type of frequency band according to the current quality information of the second type of frequency band and the preset dynamic adjustment rule, or keeping the redundancy number of the second type of frequency band unchanged and taking the historical redundancy number of the second type of frequency band as the second target redundancy number;

[0068] controlling the data sending end to set a third target redundancy number greater than or equal to 1 for the third type of frequency band according to the current quality information of the third type of frequency band and the preset dynamic adjustment rule;

[0069] generating the redundancy strategy for the current quality information according to the first target redundancy number, the second target redundancy number and the third target redundancy number.

[0070] For example, the redundancy sending numbers of the frequency bands are set differentially according to the relative quality differences of the frequency bands, and the redundancy numbers are adjusted based on different signal quality evaluation criteria, such as setting multiple thresholds from high to low, taking three thresholds (Th1-Th3) as an example, reducing the redundancy number for the frequency band with very good channel quality (CQI>=Th1), keeping or increasing the redundancy number for the frequency band with moderate channel quality (Th1>CQI>=Th2), and reducing the redundancy number for the frequency band with very poor channel quality (CQI<Th2) to reduce channel occupation and power consumption, but keeping at least one sending number to continuously monitor the channel quality.

[0071] In a possible implementation, the step of controlling the data sending end to generate the redundancy strategy for the current quality information according to the current quality information and the preset dynamic adjustment rule further comprises:

[0072] controlling the data sending end to select a target frequency band with optimal quality information according to the current quality information and the preset dynamic adjustment rule, and generating the redundancy strategy for the current quality information based on the target frequency band with optimal quality information.

[0073] For example, the target frequency band based on the quality information is optimal, and the redundancy strategy for the current quality information is generated, i.e., only the quality information optimal target frequency band is occupied, which can avoid excessive occupation of the frequency band and save resources.

[0074] In a possible implementation, the step of generating the redundancy strategy for the current quality information based on the quality information optimal target frequency band further includes:

[0075] Obtaining data transmission requirements between a data sending end and a data receiving end;

[0076] Taking the quality information optimal target frequency band as a data transmission frequency band, calculating a transmission power of the data transmission frequency band based on the data transmission requirements and current quality information of the data transmission frequency band;

[0077] Generating a redundancy strategy for the current quality information based on the identification information of the data transmission frequency band and the transmission power.

[0078] For example, the data transmission requirements are taken as standard data, the transmission power meeting the data transmission requirements is calculated according to the current quality information of the data transmission frequency band, and then resource waste is avoided.

[0079] In a possible implementation, when the current quality information triggers the feedback condition, the step of calling the data receiving end to feed back the current quality information to the data sending end through a target feedback channel according to a preset protection mechanism includes:

[0080] Comparing the current quality information with historical quality information to obtain a change amount of the current quality information;

[0081] When the change amount is greater than or equal to a threshold value in the feedback condition, it is determined that the current quality information triggers the feedback condition, and the current quality information is fed back to the data sending end through the target feedback channel according to the preset protection mechanism.

[0082] For example, the current quality information is periodically obtained, and when it is detected that a channel quality indicator of any frequency band changes by more than a preset threshold value, a sending event report is triggered, and invalid feedback is avoided.

[0083] In a possible implementation, the present application provides a data interaction device based on adaptive redundancy transmission, as shown in Figure 2 The device includes:

[0085] The policy generation module 202 is configured to control the data sending end to generate a redundancy policy for the current quality information according to a preset dynamic adjustment rule according to the current quality information, and control the data sending end to send data to the data receiving end according to the redundancy policy, so as to complete data interaction.

[0086] In a possible implementation, as shown in Figure 3 The embodiment of the present application provides a terminal device 300, which comprises a memory 310, a processor 320, and a first computer program 311 stored in the memory 310 and capable of running on the processor 320. When the processor 320 executes the first computer program 311, the steps of the data interaction method based on adaptive redundancy transmission are implemented.

When the second computer program 411 is executed by a processor, the steps of the data interaction method based on adaptive redundancy transmission are implemented.
