本文介绍了一种智能化环境中子、γ监测系统的结构和性能。它们的特点是:中子监测器的体积小、重量轻、灵敏度高;γ监测器的测量电路采用电荷泵电路构成的I-F变换电路;本地数据采集器是由高速低功耗CMOS单片计算机为核心组成的;远端中心计算机采用了FLEX微计算机系统对数据进行处理,并以绘图的方式输出,给出直观、便于分析的结果。整个系统连续运行一年以上,工作稳定可靠。
This paper presents the structure and performance of a neutron and gamma monitoring system in an intelligent environment. Their characteristics are: neutron detector, small size, light weight, high sensitivity; γ monitor measuring circuit using charge pump circuit IF conversion circuit; local data acquisition by the high-speed low-power CMOS single-chip computer Core; the remote central computer uses the FLEX microcomputer system to process the data and output it graphically, giving an intuitive, easy-to-analyze result. Continuous operation of the entire system more than one year, the work is stable and reliable.
