【摘要】 随着测控领域不断提高的测试要求以及电子技术、计算机技术的迅猛发展，传统的测控仪器己越来越不能满足时代的要求(传统仪器价格昂贵、功能单一、适应面窄、自动化程度低，而且不能对被测系统综合分析和评估，直接影响着测试水平和质量的提高)，微机化、自动化、柔性化的虚拟仪器系统是当今测控仪器的发展方向。 本文研究了虚拟仪器系统的设计思想，在分析虚拟仪器系统的特点及其体系结构的基础上，提出了基于面向对象技术的虚拟仪器系统开发方法；阐述了windows环境下实现虚拟仪器的技术要点；实现了一个典型的虚拟仪器系统“VIS—1信号示波分析系统”，该系统集普通示波器、超低频示波器、存储示波器、瞬态信号记录仪、波形及频谱分析仪等多种仪器功能于一身，并具有许多传统仪器难以达到的优越功能和性能。该系统自动化程度高、可靠性高、升级容易、人机界面友好、具有宽适应范围的柔性结构、功能开发潜力大、可维护性好，具有广阔的应用前景，可广泛应用于科研、教学、生产、医学检测等需要对信号进行监测和分析的部门。更多还原

【Abstract】 With the ever-advancing testing requirement in the checking and controlling field and the development in both the electronical techique area and the computer techquice area, the traditional testing instrument increasing cann’t meet the demand of the computer time. The traditional instrument is expensive, single-functioned, inadaptable, and low-automationed, and cann’t conduct comprehensive analysis and evaluation on the system that is examined, which has:a direct effect on the improvement of testing quality as well as the testing standard. The apparatus, with the specialities such as miniature, automation, flexibility, and individual-computer managing has become the developing trendof the testing equipment today.Based on analysis of the characteristic and the system structure of the visual instrument, the paper has studied the design idea of it, put forward the exploiting methods of the visual instrument based on the object-oriented technique, exoatiated on the technique kernel of design the visual instrument under windows environment, designed a typical visual instrument "VIS-1 signal-analyzing and wave-displaying system", which integrates multi-function instruments such as general oscillograph and ULF oscillograph real-time signal recorder wave and frequency-pedigree analysis instrument .The system has more excellent functions and characteristics than traditional instruments. It has high automation and reliability, a friendly interface. It has better adaptable soft-structure, huge development potential, good maintainability, wide application prospect. It can be applied to many departments which need detect and analyze signals such as science research, teaching, production and medical detecting.更多还原
