便携式核材料中子测量系统,采用热中子探测器对核材料进行非破坏性分析（NDA）,适用于核保障领域核材料现场测量等方面。针对核材料现场测量方便、快捷等特点,需要研制测量系统专用的智能定标器。 本工作研制的专用智能定标器,采用MCS51系列单片机控制,通过键盘输入测髦时间（1～60 000s）、报警阈值（1～60 000 cps）等参数,采用低功耗的液晶显示模块进行参数及测量数据的显示,系统最大计数为999 999,且具有限值报警功能。同时带有串行接口,可以
The portable nuclear material neutron measurement system uses the thermal neutron detector to conduct non-destructive analysis (NDA) on the nuclear material and is suitable for on-site measurement of nuclear material in the field of nuclear protection. For nuclear materials on-site measurement convenient, fast and other characteristics, the need to develop measurement system-specific smart scaler. This work developed a dedicated intelligent scaler, using MCS51 series of single-chip control, through the keyboard input vogue time (1 ~ 60 000s), the alarm threshold (1 ~ 60 000 cps) and other parameters, the use of low-power liquid crystal display module Parameters and measurement data display, the system maximum count 999 999, and has a limit alarm. At the same time with a serial interface, you can
