| description | The invention relates to the technical field of power data transmission, and discloses a low-voltage power grid data compression transmission method and device based on frequency domain transformation, and the method comprises the steps: responding to a pre-input data sampling task instruction through a master station, and transmitting power data compression transmission information to an electric energy meter through a concentrator; the method comprises the following steps: performing compression preprocessing on pre-collected original power data by an electric energy meter according to power data compression transmission information so as to perform frequency domain transformation, quantitative sampling and compression processing, then collecting the compressed and preprocessed original power data by a concentrator, transmitting the data to a master station, performing inverse transformation on the data, and finally obtaining the power data. According to the method, the original power data is reconstructed, |
