嵌入式穆斯堡尔谱数据采集系统

The embedded data acquisition system for Mossbauer spectrum

尝试引入嵌入式 Linux技术 ,构建了以嵌入式实时 Linux为平台的穆斯堡尔谱实验数据采集与远程监控系统 .定制了基于实时 Linux的嵌入式实时操作系统 ,并在其上实现远程穆斯堡尔谱实时数据采集、存储、图谱显示以及数据拟合分析的嵌入式穆斯堡尔谱数据采集系统 .用户可通过互联网在远端利用浏览器或使用 Java应用程序实现实验过程跨平台的实时监控 .该系统具有使用简便、抗干扰力强、制作简便等特点 .提出一种对现有旧实验仪器进行智能化。

With the great development of the embedded and real time operating system,it becomes practical to design the hardware based on PC architecture in high end embedded applications.Especially,the research on embedded Linux is a hots pot in this area.In this thesis,we had built a remote data acquisition and monitor system for Mossbauer spectrum based on the RTLinux.This system could be accessed by the Internet browser or the Java application program specially designed for this purpose.Extensive consideration was given to the design of the system to achieve the most advantageous balance between hardware and software,i.e.,to maintain the ease of handling and full capability of hardware system without employing sophisticated hardware.The concept of the design may be applied to other experiments requiring real time data collection and online data processing facilities.
