【摘要】 本文根据中国散裂中子源(China Spallation Neutron Source, CSNS)小角散射谱仪(Small Angle Neutron Spectrometer,SANS)探测器与电子学的最新设计方案,以Centos 7为软件开发平台,采用C++编写了小角散射谱仪的数据获取系统(DAQ)软件,实现了电子学配置、运行控制、数据读出、数据存储、状态检测和错误报警等DAQ软件基本功能;采用Qt编写了DAQ图形用户界面和在线数据库操作界面;采用MySQL实现了CSNS SANS DAQ在线数据库,用于电子学配置信息和DAQ运行状态信息的存储和查询;并根据电子学和离线数据分析系统的需求,对在线数据进行处理与显示,以监测实验进程。更多还原

【Abstract】 Based on the latest schema of the detector and electronics prototype of China Spallation Neutron Source(CSNS) Small Angle Neutron Spectrometer(SANS), this paper uses CentOS 7 as development platform and C++ as programming language to accomplish the DAQ system of SANS, which can realize functions such as electronic configuration, run control, data readout, data storage, status monitor, error warning. Qt technology is adopted to develop DAQ Graphic User Interface(GUI) and online database management interface. The CSNS SANS DAQ online database is based on MySQL, which is used to store and search the electronics configure information and DAQ running status information. Monitoring experiment progress by displaying and processing data online according to the demand of electronics and data analyze system.更多还原
