【摘要】：真空鍍膜機是典型的真空應用裝置，是機電儀結合的杰出代表。當今的真空鍍膜裝置都配備了良好的自動控制系統(tǒng)。隨著真空裝置對數據采集的速度和精度的要求越來越高，為之配備性能優(yōu)良的數據采集系統(tǒng)也提上了議事日程。研究和開發(fā)高速度、高精度數據采集系統(tǒng)對于真空裝置安全生產、穩(wěn)定運行、提高效率、降低勞動強度等，都具有積極的意義。 本文介紹了鍍膜機的總體結構、發(fā)展趨勢，結合鍍膜工藝流程，討論了鍍膜機數據采集系統(tǒng)的基本框架；介紹了虛擬儀器數據采集系統(tǒng)及LabVIEW的相關概念、組成結構、性能特點、發(fā)展趨勢；分析了LabVIEW數據采集技術在鍍膜機系統(tǒng)中的應用；設計了鍍膜機運行中溫度、真空度和流量的信號獲取和變送電路；選用MP420數據采集卡作為被采集量與個人計算機的接口，構成了一個數據采集系統(tǒng)，實現了10通道數據采集；設計了基于LabVIEW的鍍膜機運行過程數據采集系統(tǒng)監(jiān)測程序，它包括：溫度、真空度與流量的監(jiān)測主模塊，系統(tǒng)面板參數設定、控制按鈕、結果顯示等輔助模塊。該程序具有多路采集、實時顯示、存儲管理等功能，，從而實現對鍍膜機運行過程的實時監(jiān)測，其采樣速率可調，歷史數據可查詢。 本文設計的虛擬儀器系統(tǒng)已經通過模擬運行。由于虛擬儀器的模塊化、開放性、靈活性的特點以及關鍵在軟件，所以其修改、更新或重置都是非常方便的，無需從頭做起。
[Abstract]:The vacuum coating machine is a typical vacuum application device and an outstanding representative of the combination of machine and electricity. Nowadays, the vacuum coating device is equipped with a good automatic control system. The research and development of high speed and high precision data acquisition system for vacuum device safety production, stable operation, improve efficiency, reduce labor intensity, etc. Are of positive significance. This paper introduces the general structure and development trend of the coating machine, discusses the basic frame of the data acquisition system of the coating machine combined with the coating process, and introduces the related concepts and structure of the virtual instrument data acquisition system and LabVIEW. The application of LabVIEW data acquisition technology in the coating machine system is analyzed, and the signal acquisition and transmission circuit of temperature, vacuum and flow rate in the operation of the coating machine is designed. The MP420 data acquisition card is selected as the interface between the collected data and the personal computer, and a data acquisition system is constructed, which realizes the data acquisition of 10 channels, and designs the monitoring program of the data acquisition system of the film plating machine running process based on LabVIEW. It includes: temperature, vacuum and flow monitoring main module, system panel parameter setting, control button, result display and other auxiliary modules. The program has the functions of multi-channel acquisition, real-time display, storage management, etc. Thus the real-time monitoring of the operation process of the coating machine is realized. The sampling rate is adjustable and the historical data can be queried. The virtual instrument system designed in this paper has been running through simulation. Because of its modularization, openness, flexibility and the key to software, it is very convenient to modify, update or reset the virtual instrument without having to start from scratch.
