Background
The smart grid analyzes massive electric power metering data through technologies such as big data, the Internet of things, data communication and artificial intelligence, and obtains the maximum value of the data, so that the performance of the electric power system is improved, and the diversified demands of electric power users are met. Along with the promotion of smart grid business and the exponential growth of power metering terminals such as low-voltage power consumption smart metering terminals, the power metering terminals generate a huge amount of power metering data at the end (user side) of a power line, including smart meter data of residential users and industrial and commercial users, low-voltage station area energy data and the like. In order to obtain the maximum value of these metering data, they need to be subjected to a fast and high-performance calculation process. The traditional mode is to access the metering terminal to a 3G/4G communication module, and transmit mass data to a remote cloud computing center for data processing through a cellular communication network. However, on one hand, the 3G/4G communication manner makes the data transmission rate dynamically change along with the change of the wireless transmission environment, so that it is difficult to ensure that all data can be quickly and reliably transmitted to the cloud computing center; on the other hand, the manner of transmitting mass data to the cloud computing center can cause the data to experience long network transmission delay, and the maximum value of the data is difficult to acquire quickly.

Data convergence delay is a major technical factor affecting model training duration and efficiency. In addition, the electric power metering terminal users have the heterogeneity of the size of the data set due to the different positions and the different data acquisition objects.

Detailed Description
In order to make the present application solution better understood by those skilled in the art, the following description will clearly and completely describe the technical solution in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
For easy understanding, referring to fig. 1, an embodiment of a channel allocation method for power carrier communication provided in the present application includes:
When a plurality of users send user request information at the same time, the power carrier communication controller needs to reasonably allocate channels, fully utilizes the transmission rates of different transmission channels, and can meet the data transmission requirements of the users. The data set size is used for the analysis of the transmission channel assignment, while the user identification is used to assign the corresponding transmission channel to a specific user.
After descending order, the queue heads of the descending user sequence and the descending channel sequence are respectively the largest data set and the channel with the fastest transmission rate. Let the descending user sequence be denoted u= { U 1 ,U 2 ,......,U M-1 ,U M M is the number of users sending the request, and U m ={S m ,u,n},S m The data set size of the mth user is represented, u is a user identifier, n is an allocation channel, and the initial value is null; s is S 1 ≥S 2 ≥...S M-1 ≥S M 。
The descending channel sequence is denoted as ch= { Ch 1 ,Ch 2 ,......,Ch N-1 ,Ch N N is the number of transmission channels, each transmission channel including a transmission rate, a channel identification and an assigned identification, denoted Ch n ={V n ,c,r},V n C is a channel identifier for the transmission rate of the nth transmission channel, r is whether the transmission channel is already allocated with an identifier, and the initial value of the identifier is F, namely, whether the identifier is not; v (V) 1 ≥V 2 ≥...≥V N-1 ≥V N . In a multi-user multi-channel transmission system, the relationship among the channels, users and the power carrier communication controller is shown in fig. 5.
No matter what relation is between the number of transmission channels N and the number of requested users M, channel allocation can be performed once in a descending order; if the number of the transmission channels is smaller than the number N < M of the users, the users without the allocation channels exist, the users do not do allocation operation, and the value of the allocation channel N is always null; if the number of the transmission channels is greater than or equal to the number of users N and is greater than or equal to M, each requesting user can be guaranteed to obtain one transmission channel in the first channel allocation process, and the transmission rate of the first allocation channel allocated by the user with the larger data set is faster, so that the data transmission efficiency is guaranteed, and the time delay is reduced.
And 104, judging whether unallocated residual transmission channels exist in the descending channel sequence, and if yes, descending the descending order of all users according to the predicted data transmission delay to obtain a descending order delay sequence.
If the number of the transmission channels is greater than or equal to the number of users N.gtoreq.M, after the first channel allocation is completed, unallocated residual transmission channels necessarily exist in the descending channel sequence, namely, the residual transmission channels are from the (M+1) th transmission channel to the N transmission channels. In order to further reduce the aggregate delay, a plurality of channels can be allocated to users with heavy transmission load, so the basis in the second channel allocation process is to predict the data transmission delay, and the prediction refers to the delay condition of the data transmission process of each user on the basis of the first allocation channel. All users are subjected to one-time descending arrangement according to the predicted data transmission delay, and a descending delay sequence is obtained; for use in the analysis of the second channel allocation.
Further, step 104 includes:
judging whether unallocated residual transmission channels exist in the descending order channel sequence, if yes, calculating predicted data transmission delay according to the size of the data set and the channel transmission rate of the first allocation channel.
And descending order arrangement is carried out on all users according to the predicted data transmission delay, so as to obtain a descending order delay sequence.
The expected data transmission delay is not estimated but calculated from the size of each user data set and the first allocated channel that has been allocated. And analyzing again according to the result of the first channel allocation, and performing targeted second channel allocation operation, so that the channel allocation process is more reliable and reasonable.
In the second channel allocation process, the user with larger data transmission delay is expected to be allocated to the channel which is earlier in the descending channel sequence, namely the channel with faster transmission rate; after the distribution is finished, whether the rest transmission channels exist in the descending channel sequence can be judged again, if so, the predicted data transmission delay is calculated continuously, and then the channel distribution is carried out until all the channels in the descending channel sequence are distributed completely.
According to the channel allocation method for power carrier communication, when channels are allocated to each user sending a request, the data set size of each user is analyzed in a targeted mode, descending order is carried out according to the data set sizes, then the transmission channels in the descending order are allocated to the users in sequence, and therefore the users with larger data sets can be guaranteed to be allocated to the transmission channels with faster transmission rates, and convergence delay is relieved from the root; under the condition of more transmission channels, a plurality of transmission channels can be allocated for users, the basis of secondary allocation of the channels is data transmission delay, the users with data transmission delay and larger delay can be preferentially allocated with the transmission channels with faster transmission rate, and the reasonable utilization of the high-rate transmission channels is ensured by the allocation of the transmission channels for two times, so that the data transmission efficiency of the users is also ensured, and the delay problem caused by heterogeneous data sets or different channel rates can be overcome. Therefore, the embodiment of the application can solve the technical problem that the data value cannot be obtained quickly because the prior art has obvious convergence time delay due to the influence of different factors.
