毕业设计论文 基于LabVIEW的智能温度压力控制系统 摘 要 LabVIEW设计的温度压力控制系统,采用了现在国际上比较先进的技术---虚拟仪器。虚拟仪器是指通过应用程序将计算机、软件的功能模块和仪器硬件结合起来，用户可以通过友好的图形界面（简称前面板）来操作这台计算机就像在操作自己定义、自己设计的一台个人仪器一样，从而完成对被测信号的采集、分析、判断、显示、数据存储等。 本文简要介绍了实心轮胎硫化生产过程，主要阐述了一种实心轮胎硫化控制系统的控制方法及其实现。硫化是轮胎生产中影响轮胎质量的一个重要环节。硫化过程受多种因素的影响，其中，温度力时间被称为硫化的三要素较复杂关键 关键词：PID控制；LabVIEW；虚拟仪器 The Intellelctual Temperature Pressure Control System Based On LabVIEW Abstract The design is the temperature pressure control system based on labview design, which uses a more advanced technology today-imitative instrument .The imitative instrument means that to conjuncte the function module of computer and software with the hardware of the instrument through the applied program，so that the user can operate the computer through a friendly figure face (short for front board) as that the user operates a personal instrument ,which is definited and designed by the user himself ,then to complete the gathering、analysing、judging、showing and data store of the measured signal. This article is a brief introduction about the solid tyre vulcanization production, mainly elaborates the control method and the implementation of one kind of solid tyre vulcanization control system. The vulcanization is a mid-production influence about tire quality in the tyre production. Vulcanization process is affected by a many factors，Among that, temperature, pressure and time was called the three elements of vulcanization. In the three essential factors, because the temperature control is more complicated in the solid tire vulcanization control system, it is taken as the key. The control system ,including the setting of the given signal of the temperature pressure 、the gathering of the signal of field temperature pressure and the control of temperature pressure and so on. To drive the executive mechanism the control the range of the valve through the output control signal of the computer, in the end, realizing the control of the field temperature pressure. Key words: solid ty
