【摘要】 设计采用 PHIUPS 公司具有 ISP 功能的单片机 P89C669作为控制核心,对反应堆中子活化系统的辐照时间实现自动检测与控制,通过气动传输装置控制样品进入反应堆和离开反应堆。安装在反应堆堆口处的光电传感器检测管道内的样品,精确控制样品的辐照时间并计算样品的冷却时间,通过串行接口实时向计算机传输样品辐照的信息,单片机驱动液晶显示器完成辐照时间、冷却时间的动态数据显示。更多还原

【Abstract】 The system,which chooses the MCU P89C669 with ISP function produced by PHIL- IPS company as the control core,examines the radiation time of the reactor neutron activation a- nalysis automatically and controls the sample getting in or leaving the reactor by the pneumatic- transmission device.The photoelectric transducer installed in the entrance of the reactor examines the sample in the pipeline,so that the system controls the sample radiation time,counts the sam- pie cooling time,and transmits the sample radiation information to the computer by serial inter- face.The radiation and cooling time are displayed dynamicly on the LCD drived by MCU.更多还原
