摘要LabVIEW 是最具代表性的图形化编程平台,也是目前国际上应用最广的数据采集和控制开发环境之一。结合THJ-3 型为实验平台。介绍了一种基于 LabVIEW8.2.1 软件开发平台和CFP 构建热工对象自动检测控制系统的方法,将这种方法应用于水箱温度-液位控制系统,对该系统进行一系列的研究测试。对运行时的水箱液位、锅炉的温度等热工参数进行监测,并把监测到的数据显示、保存和读取。并介绍了系统所采用的硬件如压力变送器、模拟传换器、CFP 控制器的功能及特点;对硬件 CFP 通道与系统软件设计如LabVIEW 程序的交互以及数据的处理方法都有一些介绍。 27547 毕业论文关键词: LabVIEW 温度液位控制 CFP 控制器
Title Research on Temperature Liquid Level Control System of CFP Tank
Abstract LabVIEW is the most representative graphical programming platform, and is currently one of the most widely used data acquisition and control development environment. Combined with the experimental platform of THJ-3. Introduces a kind of based on LabVIEW8.2.1 software development platform and CFP construct thermal object automatic detection method of control system. This method is applied to the temperature of the water tank liquid level control system, the system carried out a series of research and testing. The water level of the water tank, the boiler temperature and other thermal parameters are monitored, and the monitoring data is displayed, saved and read.. And introduced the system using hardware such as pressure transmitter, analog conversion device, CFP controller function and the characteristic, the CFP channel hardware and system software design such as LabVIEW program interaction and data processing method are introduced。 Keywords : LabVIEW Temperature level control CFP controller
