Abstract: In order to remotely monitor and access physics experiment equipment in the power-supply controlling system of the magnetic field in the Heavy Ion Research Facility at Lanzhou Cooler Storage Ring, the 32 bit kernel chip combining with CPLD logic time sequence programming is adopted to design the eVME bus system. The control structure that ARM network control panel combines with data processing DSP board is also adopted to realize the synchronous control to power system of the magnetic field in the ion acceleration process. This system can stably achieves the dependable access and rapid acquirement of data.
