SX2型微机感应同步器位移测量仪的研制

Development of SX2-Microcomputer-Inductosyn Displacement Measuring System

本文介绍了ＳＸ２型感应同步器微机位移测量仪（数显表）的工作原理，系统硬件、软件的结构特点，着重讨论了ＳＸ２型位移测量系统独特的激磁方式─—三角波激磁。提出了一种新颖的相位扫描鉴相原理，使该机的模／数转换电路比一般数显表的简单，并且具有良好的抗干扰能力；在动态进借位逻辑支持下，本系统获得了很高的位移测量响应速度。

This thesis describes the operating principle of the SX2-type microcomput-er-inductosy measuring system(Digital Readout),recounts its characteristics of hardwareand software. The idear of using triangular wave to drive inductosy is proposed for the firsttime in inductosy measuring system. After compering and analysing,indicated the advan-tage of this driving way.A new principle of phase scanning discriminating is used forA/D(analogue to digit)conversion,therefore its A / D converting circuit is much sim-pler than that of traditional ones,moreover it obtains a verv fast response speed.
