为满足防火试验室高精度、实时性和多任务测控的需求，设计了一种基于Labview的测控系统。防火试验室测控系统由采集测试、灭火剂浓度测试、航电仿真、试验室模拟电源、试验室监视和总控台组成。提出了系统的总体设计方案，并对各个功能模块进行介绍。采用Labview软件编制测控软件，大大提高了测控系统的运行效率。合理配置Labview 软件的实时引擎，使测控系统的任务循环周期达到高精度，提高了系统的实时性。该系统具有多功能、高精度、实时性、运行稳定、界面友好的特点，能够满足防火试验的测控需求，并具有很好的应用前景，可广泛应用于各种试验之中。%To meet the high-precision, real-time, and multi-task measurement and control requirements of the fire laboratory, a kind of measurement and control system based on Labview is designed. The measurement and control system of fire laboratory is composed of acquisition testing, fire extinguishing agent concentration testing, a-vionics simulation, laboratory power supply simulation, laboratory surveillance, total control table. This paper puts forward the design scheme of the whole system, and each functional module is introduced. The software of measure-ment and control using Labview greatly improves the operating efficiency of the measurement and control system. The reasonable configuration of Labview real-time engine makes the task cycle of the measurement and control sys-tem achieve millisecond level, which improves the real-time performance of the system. This system has the fea-tures of multi-function, high precision, good real-time performance, stable operation, and friendly interface, which can be satisfy measurement and control requirements of the fire test. The system has a good application pros-pect, which can be widely applied in all kinds of tests.
