液压脉冲疲劳试验机的数据采集与处理设计

Pulse Hydraulic Fatigue Testing Machine's Data Acquisition and Processing Design

介绍一种应用于液压脉冲疲劳试验机的数据采集及数据处理的设计方案。A/D卡的数据采集以块为单位进行,由硬件逻辑电路控制采集。在一个数据块采集的同时,计算机即可将前一个数据块读出后进行计算、显示、作图等操作,保证了所有数据的不间断性。使用者可以根据需要来选择不同方式的数据显示、实时作图、保存数据、回放数据等多项操作。为方便数据处理,还可将本系统采集的数据格式转为Excel表格程序可以接受的数据格式。

This article described the application of a pulse hydraulic fatigue testing machine＇ s data acquisition and data processing design. Data acquisition is in blocks controlled by the logic circuit. While a data block collected, the computer reads previous data block and performs calculation, display, mapping and other operations to ensure data integrity. Users can conduct the real-time mapping, preservation of data, data playback operation, and so on. To facilitate data processing, the system can convert collect data to Excel data format.
