桶装核废物分段伽马扫描和层析伽马扫描自动检测系统设计

摘要

ABSTRACT A segmented gamma scanning and tomographic gamma scanning automatic detection system was designed to make the process of nuclear waste barrel detection more standardized and convenient. A motion control system was designed based on a Siemens S7-1200 programmable logic controller, and PC control and analysis software was developed based on the C#language. The accurate control of a mechanical motion device and orderly detection in a non-destructive assay system were realized. A human interface was designed to allow a user to control the experimental platform. Automatic mechanical control execution, data collection, and energy spectrum analysis were realized, while simultaneously providing auxiliary functions such as mode switching and security monitoring. This detection system promotes the synergy and integration of motion control, energy spectrum detection, and data analysis in an automatic detection process for barreled nuclear waste.%为了使核废物桶检测过程更加规范、便捷,设计了分段γ扫描和层析γ扫描自动检测系统.基于西门子S7-1200可编程逻辑控制器设计运动控制系统,基于C#语言开发上位机控制分析软件.实现无损检测系统中机械运动装置的精确控制、运动检测的有序进行;设计人性化界面以便于用户操控实验平台,实现机械控制、数据采集、能谱分析的自动执行;同时提供了模式切换、安全监测等辅助功能.促成了桶装核废物多种自动检测方式过程中运动控制、能谱探测与数据分析的协同化、一体化.
