Aiming at the poor real-time performance of single-channel grouping power consumption data acquisition, an intelligent data acquisition method based on symmetric mathematics is proposed. SM4, AES, DES, and RC6 are selected as the objects to design the top-level architecture of the symmetric key algorithm to ensure the integrity and confidentiality of the power consumption data of single channel grouping in the smart grid communication logic structure. Based on the microprocessor STM32F103RBT6, the power consumption data of single channel grouping collector is designed. The collector uses the data balance-based data acquisition routing mechanism to automatically adjust the sampling period, the adjustment factor, and the matching ratio of the reconstructed output of the single-channel packet data. Finally, the power consumption data of single channel grouping is completed. The experimental results show that the long-distance transmission time and important telemetry transmission time obtained by this method are 1.51 s and 1.47 s respectively, which are only about 50% of the standard requirements. The CPU load is 6.40%, which is only 23.7% of the standard CPU load demand, and the transmission failure rate and delay of power consumption data are relatively low. [ABSTRACT FROM AUTHOR] |
