摘 要
隨著科學技術的發展，對數據的準確度有越來越高的要求。以前的拉力測試主要是用人來測量。但是在測量當中經常會出現受力的不均衡，次數計算的錯誤等問題。這些導致數據的結果出現很大的誤差，使產品質量出現很大的問題。目前國內相應的測試設備智能化、自動化程度不高，為此需要一體化智能型拉力測量試驗儀。
論文討論了拉力檢測的原理，設計了拉力測試系統。設計出基于松下(Fp∑-c32)PLC，Proface觸摸屏(GP37W2)，壓力傳感器，步進電機的拉力測試系統，只要把待測繩索裝上測試臺，就能自動進行拉力測試試驗。系統可以根據不同要求，改動實驗參數，從而達到不同的目的。本設計還采用了觸摸屏作為人機界面，通過觸摸屏的操作可進行參數設置，實現對各種功能的控制，同時還能通過觸摸屏顯示測試結果和對系統當前運行狀態進行實時的監控。
關鍵詞:拉力測試;PLC;步進電機;觸摸屏
Abstract
With the development of science and technology, the accuracy of the data to have higher requirements. The tension test is mainly used to choose and employ persons. But often appear in the measurement of the unbalanced force ，calculation error number and so on. These data results appear much error, make product quality problems appeared. At present domestic corresponding testing equipment, intelligent, automation degree is not high, therefore, it is necessary to measure tensile test instrument integrated intelligent.
The paper discusses the principle, design tension test the tensile test system. Panasonic (Fp is designed based on PLC∑ - c32) screen (GP37W2), Proface pressure sensor, stepping motor tensile test system, as long as the rope on one measure, it can automatic tension test test. According to the different requirements, the system can alter experimental parameters, so as to achieve different purposes. This design is also used as a touch screen man-machine interface, through the operation parameters can be set to realize control, also can pass the screen test results of the system and the real-time monitoring.
