介绍工程机械关键传动部件——液力机械传动变速器总成检测试验台测控系统软件的研制。阐述了检测试验台测控系统软件的设计思想和软件结构框图,重点介绍在Windows98操作系统上用VB6.0平台对采集卡/控制卡软件的编程,开发一套完整适用的检测试验台测控系统软件。实现了检测试验台的自动化操作,测试精度高,数据处理功能强,还具备了计算机控制换挡和变速泵启动试验的功能,扩大了试验台的试验范围。
Describes the key components of construction machinery - Hydrodynamic transmission assembly testing test bed test and control system software development. The design idea and software block diagram of the test and control system software are introduced. The programming of the acquisition card / control card software on the Windows98 operating system is mainly introduced. A complete set of applicable test and control system software . It realizes the automatic operation of testing test bed, high testing accuracy and strong data processing function. It also has the functions of computer controlled shift and variable speed pump start-up test, and expands the test range of the test bench.
