摘要
本文提出了一種扭簧檢測和分析系統(tǒng)，這是不同于傳統(tǒng)的扭簧探測器。本設(shè)計基于虛擬儀器軟件與多通道信號采集。這里有兩個特征量，扭轉(zhuǎn)角度和扭矩，可以通過計算機收集，并進(jìn)行分析和處理，這種計算機擁有大型倉儲能力和較強的分析能力，數(shù)據(jù)的存儲與顯示為二維圖形格式。

簡介
扭轉(zhuǎn)彈簧的重要性是不言而喻的，作為一個大量的重要基礎(chǔ)廣泛的產(chǎn)品和應(yīng)用，它是用在幾乎所有領(lǐng)域的國民經(jīng)濟的發(fā)展。隨著公司的不斷發(fā)展，監(jiān)測和控制技術(shù)，該檢測方法越來越自動化。
與傳統(tǒng)的檢測方法非常不同的是，扭轉(zhuǎn)彈簧，徐您儀器檢測技術(shù)，作為一種特殊的測試技術(shù)的研究開發(fā)領(lǐng)域，為各種負(fù)責(zé)測試系統(tǒng)提供了更好的解決方案。而如今LabVIEW已經(jīng)用于測試領(lǐng)域，特別是自動測試領(lǐng)域，和最廣泛使用的開發(fā)平臺。
建筑結(jié)構(gòu)系統(tǒng)
虛擬儀器一般可分為兩部分：硬件和軟件。它包括計算機、應(yīng)用軟件和硬件設(shè)備。在這篇文章中，都是用的是基于amd4000+,1GHz RAM的硬件平臺，MS xp2的軟件系統(tǒng)。應(yīng)用軟件基于編程環(huán)境，寫在LabVIEW8.5。該儀器硬件是建立在芯片C8051F020基礎(chǔ)之上的。由于測試扭轉(zhuǎn)角角度和扭矩，多個傳感器的采集需要收集數(shù)據(jù)。硬件系統(tǒng)的設(shè)計包含了信號采集傳輸?shù)臄?shù)據(jù)采集板、顯示和分析的計算機。換句話說，數(shù)據(jù)采集版主要發(fā)揮信號采集的作用，數(shù)據(jù)的每一次被吸收都將將通過串口發(fā)送到電腦，在LabVIEW簽證接口作為信號處理。（見圖2）
Abstract:
This paper presents a torsion spring
detection and analysis system which
is different from traditional
torsion spring detector. The design is based on virtual
instrument software with multi-channel signal
acquisition. Two characteristic quantities,
torsion angle and the to
rque, are collected and will be
analyzed and processed by the co
mputer, which owns large storage
capacity and strong analyze ability,
to store and display the data as the
format of two dimensional graph.

0. Introduction
The importance of torsion spring is by no means self-evident. As a large amount of important
foundation for a wide range of products and appli
cations, it is used in almost all the fields of the
national economy. With the continuous dev
elopment of measurement and
control technology, the
detection methods are becoming more and more automated.
Very different from the traditional
detection method for torsion spri
ng, virtual instrument detection
technology, as a special test technology research and deve
lopment area, provides much better solutions
for a variety of complex test
systems.LabVIEW has been used in the te
st fields, in particular auto-test
