Description

Technical Field

[0001] The present invention relates to the field of communications, and in particular to an idle state performance evaluation method and system based on power grid data transmission. Background Art

[0002] In the current field of power grid data transmission, with the rapid development of smart grids, the requirements for data transmission reliability and efficiency are increasing. However, existing power grid data transmission performance evaluation methods have some shortcomings. Many existing performance evaluation methods focus solely on single metrics such as data transmission throughput or latency, while ignoring key parameters such as packet loss rate, concurrency, and error correction, resulting in incomplete and inaccurate evaluation results. During data transmission, the integrity and reliability of critical data are crucial to the security and stability of power grid operations. However, existing evaluation methods often fail to provide special processing and protection for critical data, which can easily lead to loss or corruption of critical data during transmission. Traditional evaluation methods typically treat data packets as a whole for transmission and evaluation, lacking detailed processing and analysis of the data fields within the packets. This approach makes it difficult to accurately reflect the specific performance of the data transmission channel when transmitting different types of data, thus affecting the accuracy of the evaluation results. The power grid data transmission environment is complex and changing, and the performance of the transmission channel is also affected by various factors and changes. Existing evaluation methods often lack dynamic adaptability and cannot adjust evaluation strategies and parameters in real time to cope with these changes.

[0003] To address the above issues, the present invention proposes a method and system for evaluating idle-state performance of power grid data transmission. This method marks and separates key data fields within data packets to form data sets, which are then transmitted separately into transmission channels. At the receiving end, key parameters such as packet loss rate and transmission efficiency are calculated to comprehensively and accurately evaluate the performance of the transmission channel. This evaluation method not only improves the accuracy and comprehensiveness of the evaluation but also facilitates the development of more optimized transmission strategies for specific transmission channels, further enhancing the efficiency and reliability of data transmission. Summary of the Invention

[0004] In order to solve the above-mentioned problems in the prior art, the first purpose of the present invention is to provide an idle state performance evaluation method based on power grid data transmission, by marking the key data in the data packet and splitting it into data sets, and transmitting it to the transmission channel, calculating the packet loss rate and transmission efficiency of the transmission channel, so as to achieve the effect of measuring the idle state performance of power grid data transmission and evaluating the data transmission performance.

[0005] In order to solve the above problems in the prior art, a second object of the present invention is to provide an idle state performance evaluation system based on power grid data transmission, which is used to implement the above performance evaluation method.

[0006] To achieve the above objectives, the present invention provides a method for evaluating idle state performance based on power grid data transmission, comprising: S1: Obtain the data packet to be tested in the network to be tested, confirm the key data fields that need to be split by analyzing the data fields in the data packet to be tested, and obtain key data confirmation information. The key data confirmation information can avoid the problem of data corruption and unreadable due to damage to key data during splitting, and ensure the integrity of key data during the data packet splitting process.

[0007] S2: splitting the data packet to be tested, extracting key data from the data packet to be tested according to key data confirmation information, and retaining other data as data a for normal transmission; by separating the key data from the original data packet, independently analyzing and transmitting it.

[0008] S3: Split the key data into data sets [a1, a n ], where a1 to a n The data set [a1, a n ] are all equipped with identification features; by dividing key data fields into several data, the data accuracy in data tracking can be refined and the bandwidth pressure during transmission can be reduced.

[0009] S4: The data a and the data set [a1, a n ] is transmitted through the transmission channel, and the transmitted data is received at the receiving end to obtain the working information of the transmission channel; through the actual transmission process, the performance of the transmission channel when transmitting critical data and non-critical data is obtained, and subsequent performance evaluation parameters are obtained.

[0010] S5: According to the working information of the transmission channel and the identification information in the data, calculate the relationship between data a and the data set [a1, a n ]The performance evaluation results are obtained by measuring the packet loss rate and transmission efficiency of the transmission channel.

[0011] As a further improvement of the present invention, the key data is a number of data fields with obvious identification features, the data set [a1, a n ] contains complete data information, and the data set [a1, a n ], and the data set [a1, a n] is identical to the data fields contained in the key data. By identifying data fields with distinct identification features in the key data fields, key data can be accurately located and extracted when the data packet is split, reducing the risk of data damage and data loss. By splitting the key data into non-intersecting data elements, the thoroughness and independence of the data splitting are guaranteed, avoiding data redundancy and statistical errors caused by data splitting. And by ensuring that the union of each data in the data set is consistent with the key data, it is ensured that no key data is lost during the transmission process.

[0012] As a further improvement of the present invention, in S5, calculating the packet loss rate of the transmission channel includes: comparing the number of transmission data fields received by the receiving end of the transmission channel with the number of original transmission data fields, and obtaining the packet loss rate of the data transmission channel by comparing the proportion of the difference between the number of original transmission data fields and the number of transmission data fields received by the receiving end in the original transmission data.

[0013] By comparing the difference between the number of original transmission data fields and the number of transmission data fields received by the receiving end, and calculating the proportion of this difference in the original transmission data, the packet loss rate of the data transmission channel can be accurately obtained, ensuring the accuracy of the evaluation results.

[0014] As a further improvement of the present invention, the packet loss rate is calculated as follows: ; Where P is the packet loss rate of the transmission channel, R is the number of original transmission data fields, and R0 is the number of transmission data fields received by the receiving end.

[0015] As a further improvement to the present invention, the transmission efficiency of the S5 transmission channel is calculated by calculating the amount of data passing through the transmission channel per unit time based on the transmission data received by the receiving end, and calculating the amount of data retransmitted due to transmission errors in the transmission channel to obtain an error adjustment factor. Furthermore, the concurrency adjustment factor is calculated by calculating the data concurrency rate of the transmission channel. The use of the error adjustment factor and the concurrency adjustment factor can improve the comprehensiveness and accuracy of performance evaluation.

[0016] As a further improvement of the present invention, the transmission efficiency is calculated as follows: ; Wherein, bps is the transmission efficiency of the transmission channel, D is the amount of data passing through the transmission channel, T is the transmission time of the data transmitted through the channel, ER is the data transmission error adjustment factor in the transmission channel, and C is the concurrency adjustment factor of the data transmission in the transmission channel.

[0017] As a further improvement of the present invention, the S5 identifies the data set [a1, an ] and calculate the amount of data transmitted in the transmission channel.

[0018] The present invention also proposes an idle state performance evaluation system based on power grid data transmission, comprising: A data acquisition module is used to capture the data packets to be tested from the network to be tested; The data processing module is used to analyze the data fields in the data packet to be tested, identify and confirm the key data fields that need to be split, and split the data packet to be tested, extract the key data, split it into data sets containing several data fields, and retain other data as normal transmission data a; Data transmission module is used to transmit the processed data a and the dataset [a1, a n ] Transmitting data through a power grid data transmission channel and receiving the transmitted data at a receiving end; The performance evaluation module is used to calculate the packet loss rate and transmission efficiency of the transmission channel and generate performance evaluation results.

[0019] As a further improvement of the present invention, the data acquisition module captures data packets in the network in real time, and extracts key information from the data packets by performing network communication protocol analysis on the data packets to determine key data.

[0020] By using the data acquisition module to collect data in real time and ensuring the consistency of data types according to the network communication protocol, data transmission errors are avoided.

[0021] The beneficial effects of the present invention are: (1) By using the idle state performance evaluation method of power grid data transmission of the present invention, by marking and splitting the key data fields in the data packet, the integrity and traceability of the data during the transmission process are ensured, and the overall accuracy of the performance evaluation is improved.

[0022] (2) By using the performance evaluation method of data transmission, based on the performance evaluation results, a more optimized transmission strategy can be formulated for a specific transmission channel, such as adjusting the packet size, transmission frequency, etc., to further improve the efficiency and reliability of data transmission.
