摘要
针对pNa检测过程自动化水平低、快速性差、检测精度不高的难题,以16位单片机80C196KB为控制核心,实现了pNa的自动检测与控制。介绍了在线式pNa检测仪的系统结构、工作原理、硬件电路和软件编程。结果表明该检测仪具有精度高,可靠性好,使用方便等特点,可广泛应用于工业锅炉的水质测定、高纯水的水质监督、天然水水质分析等场合。
For the problems of low level automation, slow rapidity and bad accuracy in pNa measurement, an automatic detecting and control system based on 16-bit microcontroller 80C196KB was developed.The construction, operating principle, hardware circuits and software programming of the system were described.Application results show that the measuring instrument has good performances and high reliability. It can be used widely in the fields such as water-quality determination for industrial boiler, water-quality monitor for high-purity water, water-quality analysis for natural water, etc.
