基于LabWindows/CVI的振动磨合试验台测试系统设计与实现

为了对发动机冷车试验环境参数进行测试以便掌握系统运行状况是否满足要求,在分析测试需求的基础上,构建了基于LabWindows/CVI的振动磨合测试系统.该系统以研华PCI-1715U采集卡为核心搭建硬件平台;在软件开发中,采用多线程技术实现对发动机冷车试验数据的实时采集、动态显示及保存,利用CVI提供的丰富的内部控件以及ActiveX外部控件实现试验数据的回放分析及测试报告的生成.实际应用表明:该测试系统性能良好,测量精度高,运行可靠,能满足对发动机冷车试验系统的测试需求.

Design and Implementation of Test System for Vibration and Running-In Test-Bed Based on LabWindows/CVI

In order to test the parameters of engine in cold running to monitor whether the system is in good condition,a test system for vibration and running-in test-bed based on LabWindows/CVI is constructed,and its hardware platform is set up by taking Advantech''s PCI-1715U acquisition card as the key component.During software development,multithread technology is adopted to fulfill data acquisition,dynamic display and data preservation,further,the rich internal controls and external ActiveX control of CVI are used to implement data playback and test-report generation.Practical application results prove that the system has good performance,high precision,good reliability,which can meet the test requirement for engine in cold running.
