摘　　要：在加速器中对磁场的控制实际上就是对磁场电源的控制。随着环中粒子能量的增加,偏转磁场将同步增加。这将要求电源控制器对磁场电源提供给定电压波形,已产生相应的加速磁场维持粒子在固定轨道上的谐振加速。为此,基于ARM,DSP,FPGA等硬件平台,采用Linux编程技术、双Buffer缓存机制和DSP编程,实现对磁铁电源波形数据的同步更新和实时监测。系统运行正常、性能稳定。The magnetic field control in the accelerator is in fact the power - supply control of the magnetic field. As the particle energy increase in ring, the deflection magnetic field will simultaneously increase. In order to realize the particles can be resonance accelerated in a fixed orbit, it will require that power - supply controller provides corresponding given voltage waveform to the power - supply of the magnetic field. Therefore, we adopt Linux programming, double buffer cache mechanism and DSP programming to achieve the power supply of magnet waveform data synchronous updates and real -time monitoring. The software system work stably and reliably based on the ARM, DSP, FPGA and other hardware platform.
