为使北京正负电子对撞机（BEPCⅡ）在运行时能快速找到磁铁电源引起的加速器束流不稳定或丢束的原因，研制了磁铁电源快速检测系统。该检测系统主要采用PXI系统，其8 h稳定度达0.005％，最快可在0.33 ms内采集一遍近500套磁铁电源电流值，所有历史数据均通过TCP／IP传输并实时写入远程MySQL数据库，从而可通过数据库的数据分析比对迅速排查电源电流稳定度问题。

To quickly find the causes of the accelerator unstable or lost beam caused by magnet power supply in Beijing Electron Positron Collider (BEPCⅡ) running ,the rapid detection system for magnet power supply was developed .The stability of the system in 8 h is about 0.005% ,and it can acquire over nearly 500 sets of magnet pow er supply current values most quickly in 0.33 ms .All data were written to the MySQL database in real time , so as to be able to quickly troubleshoot magnet power supply problem through historical data analysis and comparison .
