摘　　要：本文介绍了ASL3000测试系统校准装置的设计和实现方法,从硬件和软件的角度分别介绍了系统的硬件平台构建方法、计算机和校准装置之间的通信方式、校准适配单元设计技术以及校准软件设计技术。校准装置采用了测试系统整体校准方案,由标准仪器、校准接口、校准软件与测试系统组成一个闭环系统,通过测试系统运行校准程序对系统进行全量程、全自动校准,具有校准方便、准确、稳定、组织结构简单、容易实现的优点。通过在相同条件下进行大量的试验,给出了ASL3000测试系统的实际校准结果的不确定度,并通过传递比较法进行了验证,证实了该校准装置的可实现性和有效性。The method of design and realize the calibration system of ASL3000 test systems is introduced in this paper.From the point of view of hardware and software,construction method of hardware,communication mode between the calibration system and the computer,design technology of calibration adapter and calibration software are presented too.The calibration system use the methods of integral calibrating on the test systems.It is composed of the standard instruments,the calibration interface,the calibration software and the test systems as a closed-loop system.The test systems execute program to calibrate each parameter of the full-range automatically.The methods have the advantages of convenience,precision,stabilization,simpleness and good realizability.Based on many experiments under the same conditions,the uncertainty of measurement for calibration systems is provided.The calibration system is confirmed to be realizable and effective by transfer comparing method.
