[0037] A single-chip microcomputer data transmission method and a single-chip microcomputer according to some embodiments of the present application are described below with reference to the accompanying drawings.

[0038] As shown in Figure 1 A first aspect of the present application proposes a single-chip microcomputer data transmission method, comprising:

[0039] Obtaining the discrete data sequence of each data transmission channel in the plurality of data transmission channels to obtain the basic load of each data transmission channel;

[0040] Obtaining the conflict data sequence of each data transmission channel to obtain the load gain of each data transmission channel caused by the conflict transaction;

[0041] determining a channel delay of each of the data transmission channels;

[0042] constructing a channel load model of the multiple data transmission channels;

[0043] calculating a scheduling weight of each of the data transmission channels in a load balancing mode;

[0044] scheduling data transmission transactions of the multiple data transmission channels according to the scheduling weight.

[0045] Specifically, one data transmission of any data transmission channel is defined as a transaction, and each transaction is bound with a time point t as the execution time of the transaction. When transactions executed by two or more data transmission channels at the same time point t are written to the same target, the transactions executed by the two or more data transmission channels are determined as conflict transactions. When a transaction is determined as a conflict transaction, the submission of a subsequent conflict transaction is rejected at the data collection server side, and the corresponding conflict transaction is rolled back, so that the corresponding data collection device re-submits the transaction after waiting for a certain time. In the technical solution of the above embodiment, the channel delay of the data transmission channel is used to construct a channel load model, so that the scheduling weight of each data transmission channel in a load balancing mode is calculated based on the load model, thereby realizing efficient transmission of multiple-channel data and guaranteeing the stability and security of data transmission.

[0046] Further, in the above single-chip data transmission method, the step of obtaining a discrete data sequence of each data transmission channel in the multiple data transmission channels to obtain the basic load of each transmission channel specifically includes:

[0047] obtaining a discrete data sequence x it of each data transmission channel in the multiple data transmission channels, where 1≤i≤n, 1≤t≤T, n is the number of data transmission channels, and T is the time point corresponding to the end value in the discrete data sequence;

[0048] calculating a basic load P

[0049] In the above embodiment, it is assumed that the ith data transmission channel submits T data transmission transactions in a period of time, each data transmission transaction is bound with a time point t, and the amount of data transmitted is x it , so that the basic load P iT of the ith data transmission channel from time point 1 to time point T can be calculated.

[0050] Further, in the above single-chip data transmission method, the step of obtaining a conflict data sequence of each of the data transmission channels to obtain the load gain of each of the data transmission channels caused by conflict transactions specifically includes:

[0051] obtaining a conflict data sequence x' of each data transmission channel in the multiple data transmission channels it′ , wherein 1≤i≤n, 0≤t'≤T', n is the number of data transmission channels, T' is the time corresponding to the end value in the conflict data sequence;

[0052] calculating the load gain of the data transmission channel

[0053] The occurrence of the conflict transaction is random, and in an extreme case, the T data transmission transactions are all non-conflict transactions or all conflict transactions, so the value range of T' is 0≤T'≤T, and the conflict data sequence x' it′ is a subset of the discrete data sequence x it .

[0054] Further, in the single-chip microcomputer data transmission method, the step of determining the channel delay of each data transmission channel specifically comprises:

[0055] determining the average value of the discrete data sequence of each data transmission channel

[0056] Further, in the single-chip microcomputer data transmission method, the step of determining the channel delay of each data transmission channel specifically comprises:

[0057] determining the data dispersion of each data transmission channel

[0058] Further, in the single-chip microcomputer data transmission method, the step of determining the channel delay of each data transmission channel specifically comprises:

[0059] determining the channel delay of the corresponding data transmission channel according to the basic load, the load gain and the data dispersion of each data transmission channel

[0060] Further, in the single-chip microcomputer data transmission method, the step of constructing the channel load model of the multiple data transmission channels specifically comprises:

[0061] constructing the channel load model according to the channel delay

[0062] In the technical solution of the above embodiment, the channel delay of each data transmission channel is calculated by using the discrete data sequence not containing conflict transactions, and the channel load model is constructed by using the channel delay. For a business scenario without conflict transactions or with a small number of conflict transactions, the above embodiment can simplify the data processing steps and save the computing resources of the device.

[0063] In another embodiment of the present application, the step of determining the channel latency of each of the data transmission channels specifically comprises:

[0064] determining the average value of the discrete data sequence of each of the data transmission channels

[0065] determining the data dispersion of each of the data transmission channels

[0066] determining the channel latency of the corresponding data transmission channel according to the base load, the load gain and the data dispersion of each of the data transmission channels

[0067] Further, in the above-mentioned single-chip data transmission method, the step of constructing the channel load model of the multiple data transmission channels specifically comprises:

[0068] constructing the channel load model according to the channel latency

[0069] The technical solution of the above-mentioned embodiment can truly reflect the real load of each data transmission channel, and can more accurately realize the scheduling of each data transmission channel in a service scenario where the channel load gain is high due to conflict services.

[0070] Further, in the above-mentioned single-chip data transmission method, the step of calculating the scheduling weight of each of the data transmission channels in the load balancing mode specifically comprises:

[0071] determining the total system load at T time

[0072] Further, in the above-mentioned single-chip data transmission method, the step of calculating the scheduling weight of each of the data transmission channels in the load balancing mode specifically comprises:

[0073] calculating the scheduling weight of each of the data transmission channels at T time according to the channel load model

[0074] Further, in the above-mentioned single-chip data transmission method, before the step of scheduling the data transmission transactions of the multiple data transmission channels according to the scheduling weight, it further comprises:

[0075] according to the load gain ΔP of the data transmission channel iT′ configuring the scheduling offset compensation of each data transmission channel wherein τ is the load gain pre-coefficient, and 0<τ<1, t0 is the preset offset compensation base.

[0076] The transaction submission time of each data channel is dynamically offset by using the scheduling offset compensation, and when the load gain of a certain data transmission channel is greater than the preset proportion of the basic load, the scheduling offset compensation value is negative, so that the transaction submission time of the data transmission channel is advanced, thereby reducing the probability of conflict transactions.

[0078] The application provides a single-chip microcomputer data transmission method and a single-chip microcomputer, which acquires discrete data sequences of each data transmission channel in a plurality of data transmission channels to obtain the basic load of each data transmission channel, acquires conflict data sequences of each data transmission channel to obtain the load gain of each data transmission channel caused by conflict transactions, determines the channel time delay of each data transmission channel, constructs a channel load model of the plurality of data transmission channels, calculates the scheduling weight of each data transmission channel in a load balancing mode, and schedules data transmission transactions of the plurality of data transmission channels according to the scheduling weight, so that the data transmission efficiency is high, and the stability and security of multi-channel data transmission are guaranteed.
