2019 Electric Competition Question C National First Code (Line Load Is Fault Detection Device)

Outstanding works of e-sports competition in 2019

Overview

The topic was Question C: line load or fault detection device, which won the first prize in the country. Using DDS frequency sweep technology, AD9851 is used to output sine waves of different frequencies through STM32 using IIC protocol. After passing through a series of signal modulation circuits, it is detected on the two-port network of the line, voltage and frequency values are collected, and signal processing is performed through STM32 to obtain different Port load information and network identification.
