摘要
为满足便携测量γ能谱并识别核素的功能要求,设计了一种基于Windows CE的手持便携式γ能谱核素识别仪。为了达到快速、准确识别核素的目的,根据Windows CE系统的轻便、性能稳定及功能丰富的特点,采用了基于RISC微处理器(Advanced RISC Machine Cortex-A8,ARM)的S5PV210嵌入式核心板作为主控板,定制底板、外扩通讯接口等,使得仪器轻巧便携、操作方便以及低功耗。在整机平台测试中,对处理程序中运用萨维茨基第一类滤波器的谱线光滑,对称零面积法寻峰以及核素识别等效果进行了评估。实验结果表明:仪器能快速、准确识别基本核素。
[Background] Nuclide identification plays an important role in applications of nuclear technology.[Purpose] This study aims to design a handheld radio gamma spectrometer radionuclide recognizer based on Windows CE to meet the functional requirements of portable radionuclide measurement and identification.[Methods] In order to achieve the purpose of quickly and accurately identifying the nuclide, the embedded ARM(advanced RISC machine Cortex-A8) core board of S5PV210 is used as the main control board which has the characteristics of light, easy to operate and low power consumption. The stable performance and rich function of the Windows CE system make it easy to implement data acquisition and processing algorithms. The smoothing effect of Sawicki's first filter, the effect of symmetrical zero area method and nuclide identification were evaluated during the platform testing of the whole system. [Results] The experimental results show that the instrument can identify the basic nuclide quickly and accurately. [Conclusions] The design improves the efficiency of the whole machine and meets the basic requirements.
