摘  要
 “力”這個概念在我們生活中已經是司空見慣了，生活中有很多工具可用來測量，如彈簧秤、紐秤、握力器等，這些工具都是簡單的機械式測量，雖然使用方便，但是準確度卻不高。而且對于像卷尺、牽狗繩這類拉力隨著長度而改變的力很難測量出來。本文研究了拉力測試的原理及方法，利用PLC、觸摸屏、力傳感器、A/D轉換器、步進電機夠了的系統來實現拉力的測試。系統通過觸摸屏設計了人機界面，操作簡單，具有現實意義，便于企業對其產品的合格檢測等。
 
關鍵詞： 拉力測試，PLC，觸摸屏，步進電機

Abstract
 The concept of force is common in our life and there are many tools that can be used to measure force, such as spring balance, new balance, etc, these tools are very simple, although they are used conveniently, but not have high accuracy. And the pulling force which changes as long as its length change is difficult to measure, such as tape, the dog rope and so on.In this paper we make a study of the principle and method of tension tests, moreover, we do the tension test with a system which is constructed with PLC and touch screen, sensors, the A/D converter and stepping motor. In this system we designed a man-machine interface by touch screen, it can be operated simplify and have practical significance, what’s more it can be used to do product qualified inspection.
 
Key words: tension tests, PLC, touch screen, step motor
