虚拟仪器技术是计算机技术与仪器技术相结合的产物，代表了仪器的最新发展方向，它把传统仪器中的某些硬件乃至整个仪器都用计算机软件替代，这样不仅可以节省硬件开支，而且缩短了研发时间，减小了设计难度。本文正是基于NI公司LabVIEW的虚拟仪器软件开发环境，探讨以LabVIEW图形化软件编程方法和集成开发环境来实现计算机测控平台的技术和方法，并将其应用在链条炉测控系统平台的设计中。 本文首先分析虚拟仪器的构成以及分类与应用，选择图形化软件LabVIEW作为测控系统的开发环境。然后，在此基础上重点研究了在虚拟仪器集成开发环境中的测控系统开发优势，提出了基于LabVIEW的测控系统设计方案，包括系统结构、功能和性能特性以及设计流程和设计方法。 通过基于优先级的设置和执行系统的选择，结合固定时间间隔调度和时间片调度以及事件驱动机制，设计实现了基于LabVIEW测控平台的三种多任务调度策略: 通过采用循环缓冲技术、高速磁盘流技术、异步读取DAQ事件技术解决了高速数据采集过程中涉及到的问题。 将利用虚拟仪器技术开发的测控平台应用于链条炉测控系统中，设计了简洁、友好的人机交互界面，实现了基于虚拟仪器集成开发环境中控制策略生成、画面监控、参数设置、参数趋势显示、报警处理以及数据库访问和网络通讯等功能。在控制算法上，研究PID参数整定方法，提出自调整模糊PID控制算法，设计的基于LabVIEW自调整模糊PID控制器，应用于链条炉测控系统平台中；在控制方案上，研究了基于LabVIEW的测控系统平台多冗余、多策略控制系统的构建方法，采用了常规控制与智能控制并存的控制方案，解决了控制方案的优化问题。

Virtual Instrument is the combine outcome between the computer and the instrument technology. It is the new development aspect of the instrument. The computer can replace the parts of the hardware, even the whole instrument. It lead to save hardware expenditure, reduce the research time and weaken the design difficult. The LabVIEW Virtual Instrument software exploder circumstance is involved based on the NI Co. in the paper. The technology and the way of the computer test and control is achieved based on the LabVIEW graphics mode programmed way and the integration exploder circumstance. Firstly, the Virtual Instrument is briefed introduced in the paper, include the form and the application of it. Then the graphics mode software exploder circumstance, the merits and the powerful functions of the LabVIEW language are showed in the paper. It is important that the computer test and control system design scheme in the Virtual Instrument exploder circumstance based on the LabVIEW is given. It include the system frame, function, performance characteristic, design flow and design way. The 3 multitasking dispatch strategies based on LabVIEW test and control flat via setting priority and the select perform system. It is connected with the changeless time interval and the time block drive machine-made. It solved the met questions during high-speed data acquisition via circle buffer storage, high-speed disk storage technology, asynchronism read DAQ incidents. A LabVIEW test and control flat, namely, grate-fired furnace is designed. A brief and friendly interface between the computer and man is realized. The process control, the picture supervise, the parameter setup, the parameter trend, given an alarm, database visit and the network communication etc are implemented based on LabVIEW the Virtual Instrument exploder circumstance in the paper.The multi-redundancy and multi-strategy control system form way based on the LabVIEW test and control flat is researched on the control project. A universality PID parameter line up and the self-regulate fuzzy PID control arithmetic is designed. And then the self-regulate fuzzy PID controller is realized based on the LabVIEW. The material application is materialized in the test system plat.
