摘要

本文為針對高速沖床設備建立一套資料擷取與監控系統，主要是使用可程式控制器控制機台之動作，並將狀態等相關資訊透過嵌入式人機介面系統的通訊傳輸介面傳送到資料庫上。當得到機台狀態資料後，將這些資料輸出於遠端之介面，故本系統架構較一般監控系統架構簡單且降低成本。藉由此遠端監控系統之建置而能縮短機器故障時的平均修復時間，同時可方便管理階層了解目前公司所有機器運作與生產情形。特別是故障排除部分，監控系統會將設備之異常訊號傳送至人機介面上，配合畫面上的故障排除說明，使操作者可立即排除簡單之異常，有些甚至不需要專業維修工程師即可自行進行故障排除動作，如此將可降低機器之故障時間與額外的維修費用。此外，系統中會顯示目前加工總計數量，當數量到達時自動停機並送出加工完成之訊號，使管理者了解目前機器工作是否完成，通知現場操作者準備進行下一筆料件之備料或進行換模及工作參數調整等作業。故經由網路監控，可大幅減輕操作人員的工作負擔、降低公司的人事成本，並提昇廠商的市場競爭力。

This thesis aims to design a data acquisition and dynamic monitoring and control system for high speed press machines. A PLC is used to control the actions of the machine and the states are transmitted to the database via the communication interface of the embedded human machine interface system. These data are then output to a terminal PC. We hope that the proposed system can shorten the mean time to repair. At the same time, the supervisor can know the operations of the machine and the situation of the productions. The monitoring and control system shows the failure status on the HMI. Therefore, the operator can easily execute the troubleshooting for the simple extraordinariness. It does not need the professional engineers to do the troubleshooting. Hence the cost and the mean time to repair can be effectively reduced. Furthermore, the system also shows the amount of the machining. When the amount reaching the setting quantity, the machine will stop automatically and send a finishing signal to the HMI. This method let the operators know to prepare the workpieces for the next machining, change the die and molds, or execute the parameter adjustment. By this monitoring approach, operator effort can be reduced. The payload and the cost of machines also can be decreased. Thus, this system improves the market competitiveness of companies.
