ER-200D-SRC型EPR谱仪微机系统的改造

详细叙述了德国BRUKER分析仪器公司ER-200D-SRC型EPR谱仪与IBM PC/386微机联机的软硬件系统,该系统综合了仪器的自动磁场扫描控制,数据采集累加和数据分析处理及数据绘图、打印等各项功能。其硬件由IBMPC/386微机及二大接口模块组成。一块为商品化的12位A/D、D/A接口卡,另一块为自行设计的以INTEL-8255可编程通用接口电路为主体的数字量输入输出控制接口卡,可分别独立地插入PC机的扩展槽中,其软件采用C语言编写,具有菜单式、结构化、模块化、汉字工作提示、实验数据实时屏幕绘图、实验参数实时显示等特点,用户界面良好,该系统恢复并提高了原谱仪的整体性能,具有一定的推广价值。

THE IMPROVEMENT OF MICROCOMPUTER SYSTEM FRO A BRUKER ER-200D-SRC SPECTROMETER

The software and hardware system was developed for use with the German BRUKER ANALYTISCHE MESSTECHNIK COMPANY'S EPR Spectrometer model ER-200D-SRC. The system was used to control spectrometer during magnetic sweeping,collect data from spectral scans in single-scan and multiscan modes, data analysis and manipulation, output data to the spectrometer x-y recorder and print data to printer,The hardware is based on IBM PC/386 computer and two interface modules, one of which is commercialized 12-bit A/D and D/A interfaced, and the other a designed digital I/O control card with a general programable interface IC INTEL 8255 being it's main body.The two cards can be inserted into PC's extension socket respectively. The software,written in C language, is characterized by chinese character menu display,structured and modularized program and real-time working.It has good user's interface and easy operation, The system has recovered and im-proved the whole funtion of the original spectrometer and has certain value for development.
