无级变速器实验台的软件设计

Design of Software for Automobile CVT Experiment System

基于对车辆无级变速器实验台总体设计方案的分析,确定了配套的硬件、端口的分配及开发软件。进而得出系统软件的设计任务,最终以LabVIEW软件作为系统的开发平台,设计了信号波形显示、高级采集、虚拟仪表、信号模拟、信号复位、窗口最大化等软件模块。软件系统作为实验台的重要组成部分,与硬件系统相互协调,实现了系统的虚拟测控功能。

Base on the analysis of total design, the supporting hardware, port assignments and developing software is decided. Then the design task of the system software is introduced in this paper. At last, software modules of signal waveform displaying, advanced data acquisition, virtual instrument, signal simulating, signal resetting and window maximizing are developed on the Lab VIEW development platform. Being an important part of the experiment system, the software system is coordinated with the hardware to achieve the goal of virtual testing and controlling.
