摘　　要：在强电磁脉冲环境下,通信对系统的稳定工作、监控具有至关重要的作用。针对PFN系统中对B探针信号检测、网靶信号检测及触发放电时序控制问题,从安全性,可靠性出发,基于DSP给出了一种由光纤通信、RS485和RS232的混合通信设计方法。通过现场试验结果表明,在PFN放电强脉冲电磁干扰下,数据收发正常,系统运行稳定,得到良好的通信效果。Communication is very important for the stability and the monitor of system in the environment of a strong electromagnetic pulse. A hybrid communication design approach which is composed of optical fiber communication,RS485 and RS232 is proposed based on DSP. In this approach,the signal detection on capacitor B probe and net target and the sequential control of trigger discharge are discussed from a security and reliability point of view. Field tests have shown the transfer of data is normal in the presence of the electromagnetic interference of PFN discharge pulse; meanwhile the system is stable and achieves effective communication results.
