AI Technical Summary

Technical Problem

Existing Raman distributed fiber optic sensing data acquisition systems suffer from problems such as bulky equipment size, high power consumption, poor real-time performance, and poor reliability. Furthermore, they suffer from high data processing latency, making it difficult to meet the requirements for real-time performance and reliability.

Method used

A data acquisition, processing, and transmission system based on ZYNQ is adopted. By deploying an LVDS data acquisition module, a first DMA module, a wavelet threshold denoising module, and a data demodulation module at the PL end of the ZYNQ module, and setting an AXI_MASTER control module in the first DMA module, the data interaction mechanism between modules is optimized to achieve fast response and data transmission.

Benefits of technology

The system size has been reduced, the response speed has been improved, and the requirements of distributed fiber optic sensing for multi-task real-time performance and data integrity have been met.
