Microcomputer Measuring System for the STY Hydraulic Motor Speed Reduction Testing Device

本文介绍了ＳＴＹ油马达减速机械调试台微机测试系统的应用、组成和特点，提出了一种数据均分滑动滤波方法，有效地消除了测量过程中的误差于扰信号，尤其是工频（周期）干扰信号，对于多模拟通道共享一个模数转换器而产生的于扰误差，本文给出了用软件解决的设计方法。

A microcomputer measuring system for the STY hydraulic motor speed reduction testingdevice is developed successfully. In this paper the main technical properties, applications andconfiguration of the system are discussed. A new digital filtering approach of even sliding dataprocessing 'waS given, by which. interference errors, especially the 50 Hz frequency waves,aredecreased effectively. A software was designed for eliminating the interaction produced by anA/D converter shared by multi-port analog signals.
