摘　　要：提出了一种基于Raspberry Pi计算机的嵌入式α能谱测量装置的设计方案,基于Linux操作系统和Python语言编写程序,并利用无线网络远程控制,实现了远程α能谱测量、实时显示和数据保存等功能,软件设计过程避免了操作系统迁移、驱动开发等工作,具有开发周期短,通用于PC机的特点。内容包括α能谱仪的硬件电路、数据传输和跨平台多线程能谱软件的设计。使用^(241)Am源对测量系统主要性能进行了测试,重复性及稳定性符合要求。The paper proposed a design progrtun of α embedded alpha spectrum measurement device based on Raspberry Pi computer. Based on Linux operating system and the Python program, the device realized the re- mote α spectral measurement, real - time display and data storage. Avoiding the operating system migration and driver development in general embedded system development, this design shortens the development period, and the software is compatible with the personal computer and windows operating system. The content includes hard- ware circuit scheme, alpha spectral acquisition board,data transmission and cross platform multithreading spec- trum software design. Tested through the Am -241 source, the repeatability and stability of the measurement equipment meet the requirements.
