摘要
为适应各种工业现场 ,必须进一步提高无纸记录仪的抗干扰能力。文章设计的无纸记录仪从硬件和软件上作了一些改进 ,采用了集成看门狗电路、V/ F转换、光耦隔离技术、数字滤波等关键技术 ,使系统的稳定性与可靠性得到了较大提高。文章的研究成果已经得以在工业现场推广应用。
To adapt to many kinds of industry fields,we must improve the no-paper recorder's anti-jamming performances. In this paper,some mending methods through modifying in hardware & software are provided.It applies the watchdog circuit,V/F conversion circuit,photoelectric coupling isolation technology,digital filtering technology and etc. To make the system stability and reliability better, the research result in this paper has applied to industry field.
