摘要: 为监测离子源加速器故障短路电流和电压波形,给出了一种无人值守数字示波器的方案,其硬件上基于FPGA和单片机,软件上基于LABVIEW。相比于使用泰克示波器的传统方法,该方案有性价比高、轻便、抗强电磁干扰、基于PC远距离监控故障、自动存储故障波形等优点,能良好地模拟数字示波器波形,达到无人值守的效果。Abstract: The fault current and voltage waveforms are required to be monitored by oscilloscopes when shorting occurs in developing ITER 1 MV ion source accelerators. Therefore, it is necessary to design an automatic digital oscilloscope compatible with strong electromagnetic interference environments. Its hardware is based on FPGA and MCU, while its software is based on LABVIEW. Compared with the traditional method of using the Tektronix oscilloscope, it is cheap, small, of anti-electromagnetic interference, and can automatically store waveforms with remote monitoring.
