摘要
设计采用PHILIPS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。
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 analysis automatically and controls the sample getting in or leaving the reactor by the pneumatictransmission 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 sampie cooling time, and transmits the sample radiation information to the computer by serial interface. The radiation and cooling time are displayed dynamicly on the LCD drived by MCU.
