封闭式水力机械模型试验台APPLEⅡGPIB自动测试系统

APPLE-Ⅱ GPIB Minicomputer Automatic Measuring System for Closed Testing Stand for Hydraulic Machinery Model

在封闭式水力机械模型试验台上,采用APPLEⅡ微型计算机及有关的测试仪器组成自动测试系统,实现了水机试验过程的自动化.该测试系统是在APPLEⅡ微机内插一块7490型GPIB接口卡,通过计算机控制测试仪器的运行状态,并且指挥仪器完成水机试验过程中的数据测量任务,测得的数据通过GPIB总线在计算机上显示、存贮和处理。最后由打印机和自动绘图仪提供试验结果。

Using the automatic measuring system composed of an APPLE-Ⅱ minicomputer and measuring instruments concened on closed testing stand for hydraulic machinery model, we have accomplished the modernization of hydraulic machinery test. Inserting a GPIB interlace card in computer, we can control the measuring instruments to work and command them to finish the data measurement in the test. The collected data may be displyed, stored and handled by computer through the GPIB bus. The result of test is provided by printer and auto drawing at last.
