【摘要】 核辐射探测信号波形的数字化采集与处理方法是目前核信息获取与处理领域中的重要研究课题之一。为了给基于高速ADC和DSP的新型核信号波形采集硬件系统提供软件支持,本文专就系统软件的设计进行了讨论。 文章概述了核信号采集与分析系统的基本原理,分析了在核物理实验中对信号处理的基本要求,提出了特定的新型核信号采集系统的软件设计方案,并根据常规核测量实验要求提出了系统软件设计的主要思想。 系统以数据流程为线建立软件结构框架,从类结构的角度出发,对软件中各部分的算法进行了具体设计。采用层次模型,对整个系统进行分层设计,便于功能的扩展和软件的修改。 概述了Windows驱动程序设计的原理和一般步骤,通过接口程序的设计阐述了应用程序与硬件通信的具体实现。作为系统原型设计,文章在应用功能的设计上重点阐述了波形显示以及多道分析功能的实现。 整个软件系统在Visual C++6.0平台上调试成功。配合硬件系统,既可以作为通用的数字示波器使用,也可以作为专门的核信号测量数据处理、分析系统使用,具有实际的工程应用价值。更多还原

【Abstract】 Surveying the digitization of the signal wave form gathering with processing method in nuclear radiation is one of the most important subjects in the nuclear information obtained and dealt with search field at present. In order to support the new type system of nuclear signal wave form gathered basic on high speed ADC and DSP with software system, this text has been discussed on the design of the systems software specially.The paper has summarily introduced the basic principle with nuclear signal gathering and the analyticle system, has analysed the basic demand dealing with the signal in the nuclear physical experiment, has put forward the design plan of the specific new-type nuclear signal gathering system and has also put forward the main thought of system software design according to the requests of the general nuclear measuring experiments.The system has set up the structure frame of software with the line of the procedure of data, proceed from the point view of the kind of structure, has concretly designed the algorithm of every part in the software. It adopt the level model, divide the whole system into several layers and partly design, convenient for the expansion of the function and modification of the software. It has summarized the principle and general step of designing drive program of Windows, has explained the concretly realizing of application program and hardware communication through the design of the meeting programm. Designed as the systematic prototype, The paper explain thedesign of application function especially on wave form show and the realization of multilane analyzing function.The whole software system debug succeeding at Visual C++ 6.0 platform. Cooperate with the hardware system, it can used as the universal digital oscillograph , also used as specific processing and analyzing system of nuclear signal measureing data . have real project using value.更多还原
