Research on Design and Implementation of Terminal Multi-loop Power Monitoring Module

To address the core challenges of traditional terminal power distribution systems-such as redundant sampling, bulky size, high costs, and installation difficulties-the present study presents an end-terminal multi-circuit power monitoring module. This module features a core innovation of voltage-current sampling separation, utilizing a distributed architecture with one voltage acquisition module and multiple current acquisition modules to achieve precise collection and statistical analysis of all power parameters across multiple circuits. The research details the hardware architecture design, core circuit implementation, software layering structure, and key algorithm development. Product performance was validated through multi-signal-point and multi-condition tests.
