AI Technical Summary

Technical Problem

Traditional monitoring nodes struggle to achieve reliable monitoring in the extreme environments of nuclear fusion control devices. They suffer from reduced time synchronization accuracy, difficulties in data alignment, and insufficient self-testing capabilities, which limits the expansion of the monitoring network and reduces diagnostic accuracy.

Method used

The system employs an FPGA-based transparent transmission module, a synchronization monitoring module, and a self-test module, combined with a local clock, to achieve high coupling at the hardware level. Time synchronization and data acquisition are performed through a hardware timestamp unit, and closed-loop self-testing is conducted to ensure the accuracy of timestamps and the precision of signal processing.

Benefits of technology

Achieving high-precision time synchronization, data alignment, and self-testing in the extreme environment of nuclear fusion control devices improves the reliability and stability of the monitoring system, and supports high-parameter operation and accurate analysis of transient events.

Abstract

The application relates to a monitoring node and a monitoring system of a nuclear fusion control device. The node comprises a transparent transmission module, a synchronization monitoring module, a self-checking module and a local clock; the transparent transmission module is used for locking the inbound and outbound time stamps of a time synchronization message by using a hardware time stamp unit, obtaining a residence time increment and accumulating the residence time increment to a time synchronization message correction field; the synchronization monitoring module is used for triggering a monitoring sensor to collect data when the current time is consistent with a trigger time, obtaining a data collection result according to the incoming monitoring data and the incoming time stamp locked when the monitoring data is incoming; the self-checking module is used for locking an instruction issuing time stamp in response to a self-checking instruction, outputting a self-checking signal to a feedback transmission unit; waveform fitting is performed on the received feedback data to obtain waveform features and waveform feature time stamps; and a node self-checking result is obtained according to the instruction issuing time stamp, the waveform feature time stamps and the waveform features. The node can improve the monitoring reliability of the nuclear fusion control device.
