基于LabVIEW的智能温度压力控制系统

摘 要

本设计是基于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、压力、时间被称为硫化的三要素。影响轮胎硫化的三要素中由于对温度的控制比较复杂，所以在实心轮胎硫化控制系统中，它就成为系统控制的关键。该控制系统，包括温度压力给定信号的设定、现场温度压力信号的采集以及温度压力的调节等等。最终通过计算机输出的控制信号去驱动执行机构来控制阀门的开度，进而实现现场温度压力的控制。

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 essential 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.
