摘     要
 
 本論文介紹了一個實用的數據采集系統，為了檢查出廠電機的運行情況，更好地保證伺服電機的質量，需要對伺服電機的轉矩、轉速等參數進行采集、存儲、顯示。分析了轉矩轉速測量原理，并通過軟硬件技術結合，實現了對伺服電機的模擬量進行信號的采集與處理。本系統充分發揮了采集系統的優勢，采用模塊化設計軟件方法，設計出獨立于設備類型應用軟件。通過它可方便精確地測量轉矩、轉速，并檢測其伺服控制系統的準確度。試驗表明，該采集系統精度高、抗干擾能力強、操作簡單。
 本文還介紹了伺服電機的工作原理、分類、特點及其優勢，通過對其主要性能的分析，確定電機測試的主要參數。介紹了一種數據采集系統的實現，該系統采用數據采集模塊結合數據接口卡作為專用硬件輔助設備，通過PCI總線擴展到微機上，在視窗操作系統環境下使用軟件編程的方法，以微機作為采集控制單元經總線對硬件輔助設備進行配置和操作，實現了高采樣率的數據采集、控制和雙向通訊功能。
 本次開發數據采集系統分為硬件設計和軟件設計，本文主要介紹了系統軟件結構的設計，尤其是采集卡的選擇。并且用VB編譯出物理實驗室數據采集平臺，介紹了其操作界面和主要功能，最后對采集過程中可能產生的誤差進行具體分析。

Abstract
 This paper describes a practical data collection system. In order to check the operation of the delivery motor, servo motor should be ensure the quality to need for servo motor torque, speed and other parameters for collection, storage and display better. Analyzing of the measuring principle of torque and speed, and through software and hardware technologies， to realize the analog servo motor for signal acquisition and processing. The system put into great play advantage of acquisition system ,use the design of modular of software, and design independent of the type of device applications. It can be easily adopted to accurately measure the torque, speed, and test its accuracy servo control system. Test show that the acquisition system of high precision, strong anti-interference ability, simple operation.
 This article also describes the working principle, classification, characteristics and advantages of the servo motor. To determine the main parameters of motor tests by analyzing  the main performance. It also introduces a data acquisition system. And this system combines data acquisition module with data interface card hardware as dedicated auxiliary equipment, through the PCI bus extended to the microcomputer. And software programming is in the windows operating system. PC in used as bus in the Acquisition Control Unit, to control Hardware accessories. To achieve a high sampling rate of data acquisition, control and two-way communication.
 The development of data acquisition system can be divided into hardware and software design. This paper describes the design of software architecture, in particular the choice of capture card.  It establishes a data platform of a physics laboratory with VB , and introduces its user interface and main functions, at last analyze the error .
