Method and system for sampling monitoring data of energy internet and electronic equipment

The invention discloses a sampling method and system for monitoring data of an energy internet and electronic equipment, and relates to the field of data processing, and the method comprises the steps: obtaining a monitoring signal of the energy internet; performing sparse representation on the monitoring signals by applying a sparse representation method based on dictionary learning; carrying out compression measurement on the monitoring signal after sparse representation based on a chaotic cyclic measurement matrix of Cat mapping; and reconstructing the monitoring signal after compression measurement to obtain sampling data of the monitoring signal. According to the invention, on the premise of ensuring the information amount, the sampling data amount can be reduced fundamentally. 本发明公开一种能源互联网的监测数据的采样方法、系统及电子设备，涉及数据处理领域，该方法包括：获取能源互联网的监测信号；应用基于字典学习的稀疏表示方法对监测信号进行稀疏表示；基于Cat映射的混沌循环测量矩阵对稀疏表示后的监测信号进行压缩测量；对压缩测量后的监测信号进行重构，得到监测信号的采样数据。本发明能够在保证信息量的前提下，从根本上减少采样的数据量。
