摘　　要：脉冲星是旋转的中子星,它的平均周期非常稳定。脉冲星观测是射电天文一个非常重要的领域。文章针对东南大学研制的射电脉冲星观测系统提出了一种控制软件的设计方案,包括需求分析和实现,基于CFITSIO库,用C++开发。它运行在主控机上,用户在软件界面可以设置参数,通过PCI总线,对整个观测系统进行控制,软件界面上会实时显示频谱图,软件实时存储频谱数据为FITS格式。系统在上海天文台进行测试,测试结果满足观测要求。Pulsars are rotating neutron stars,which have stable average cycles.Pulsar observation is an important area of radio astronomy.This paper illustrates design of control software for the radio pulsar observation system developed by Southeast University.It contains analysis of demands and implementation.It is developed in C++,based on CFITSIO library.It runs on the industrial PC,whose interface that user can set parameters on through PCI bus to control the observation system,while the software displays real-time spectrum diagrams and stores real-time spectrum data in FITS format.Tests in Shanghai Astronomical Observatory show the results meet the requirements of observation.
