回取分类系统α废物在线检测实验装置是废物库退役示范工程中的一个重要环节。它利用3He中子计数管测量传送带上废物中Pu同位素发射的中子数,从而确定废物中的含Pu量,达到检测α废物的目的。 针对系统在线检测的需求和测量系统输出信号的特点,数据获取及处理系统采用了两个ISA总线的标准PC插件、IPC5387计数/定时板和IPC5375功放输出板。通过软件编程完成了中子计数、处理、报警及与主控制台的报警联动控制功能,满足系统的实时控制需求。 经现场应用表明:该系统实现了测量数据的自动获取、处理及图形化显示;实现了废物
Recycling classification system α waste on-line testing experimental device is an important part of the waste retired demonstration project. It uses the 3He neutron counter to measure the number of neutron emitted by Pu isotopes in the waste on the conveyor so as to determine the amount of Pu contained in the waste so as to achieve the purpose of detecting α waste. According to the demand of system online detection and the characteristic of the output signal of the measurement system, the data acquisition and processing system uses two ISA bus standard PC plug-ins, IPC5387 count / timer board and IPC5375 amplifier output board. Through software programming completed neutron counting, processing, alarm and alarm linkage with the main console control functions to meet the system’s real-time control needs. The field application shows that the system realizes the automatic acquisition, processing and graphical display of the measured data, realizes the waste
