中试厂核临界安全实验装置主要用于研究乏燃料后处理工艺中关键设备的核临界安全问题。在以往的实验运行中发现:对该装置运行期间的部分数据信息缺乏必要的监测和控制,给运行人员对状态信息采集与工况判断带来了一定的不便。因此,设计研制了辅助监测控制系统,对提高实验装置运行安全具有显著作用。该系统包括多个传感器、数据采集卡USB-6210、针孔摄像头、视频采集棒UV200、计算机以 The pilot plant nuclear criticality safety test device is mainly used to study the nuclear criticality safety of key equipment in the spent fuel reprocessing process. In the past experiments, it was found that the lack of necessary monitoring and control of part of the data during the operation of the device brought some inconvenience to the operators in collecting status information and judging the working conditions. Therefore, the design and development of auxiliary monitoring and control system has a significant effect on improving the operational safety of the experimental device. The system includes multiple sensors, data acquisition card USB-6210, pinhole camera, video capture stick UV200, the computer to
