摘要: 介绍了FAIR项目Super-FRS超导二极磁铁样机的基于FPGA的失超探测系统。该失超探测系统采用平衡桥路法，并通过两组独立桥路以消除失超探测死区。通过NI PXI7830R FPGA模块实现平滑滤波和失超判断算法，并给出失超触发信号。失超数据采集模块采用预采样技术，将失超前后一段时间内的数据采集下来，以便进行后续分析。通过测试，失超探测模块准确检测到了失超的发生，并触发失超保护电路和失超数据采集模块工作，有效地保护了超导二极磁铁。： The quench detection system for SuperFRS superferric dipole prototype magnet of FAIR has been designed and built. The balance bridge was used to detect quench signal. In order to avoid blind zone of quench detection， two independent bridges were used. NI PXI7830R FPGA was used to implement filter to quench signal and algorithm of quench decision and to produce quench trigger signal. Presample technique was used in quench data acquisition. The data before and after quench could be recorded for analysis later. The test result indicated that the quench of the dipole’s superconducting coil could be reliably detected by the quench detection module.
