Abstract

This invention provides a multi-channel spectrum analysis system, method, electronic device, and storage medium, relating to the field of AC power supply technology. The system includes an ARM control unit and an FPGA control unit. The ARM control unit determines the current channel to be analyzed from preset channels and generates identification information. The FPGA control unit samples the channel to be analyzed based on the identification information, writes the sampled data into a buffer of preset size, and generates a data ready indication signal when the buffer is full. The ARM control unit reads the sampled data from the buffer based on this signal, analyzes it, and generates identification information for the next channel to be analyzed after obtaining the spectrum analysis result, until the spectrum analysis of all preset channels is completed. This invention achieves low-cost, high-precision, and high-efficiency multi-channel synchronous spectrum analysis through heterogeneous collaboration between ARM and FPGA, eliminating the need for an external synchronization clock. It solves the problems of low integration, complex synchronization, and poor phase accuracy in existing technologies.
