【摘要】 传动误差TE（Transmission Error）及单端运动的速度、加速度等运动特性MP（Motion Property）的动态精密测量涉及光、机、电，磁和计算机等多门学科的前沿技术，在生产中有着非常重要的意义。“全微机化传动误差检测分析系统”（FMT系统）是以微机为核心，将脉冲信号细分原理与微机应用相结合的新型传动误差分析系统，甩掉了传统仪器的细分、比相等复杂硬件电路，构成无电器箱测试系统。本课题“分位式传动误差测试系统的下位机关键技术研究”是对原有的FMT系统进行进一步的升级研究。软件上，屏弃枯燥的ＤＯＳ界面，使用Windows平台实现实时性很高的实测实显任务；硬件上，将计算机作为上位机，单片机作下位机，连成简单的网络，实现高精度的、具有远程控制能力的一种分布式测试系统。下位机系统由大量的数字电路组成，为了提高系统的稳定性，我们用专用集成电路ASIC代替了分立元件。系统的主要理论特色在于脉冲信号细分的一种新观点和微机实现方法。在研制过程中，同时开发出一种单片智能信号发生器，在调试和自检中发挥很大作用。本文最后给出了实验结果及误差曲线。更多还原

【Abstract】 The dynamic precision measurements of property such as transmission error, single shaft motion speed and acceleration and so on , involve in frontal technologies about subjects including optics, mechanics, electricity, magnetism and computer .And these measurements play an important role in many manufacture fields.The Full Micro-Computerized Test and Analyzing System for Transmission Error and Motion Property (FMT), whose core is micro-computer, is a new system for TE test and analyzing, combining plus signal subdivision theory with computer, and all test work is completed by it, so the test become "no instrument box test system". And our research ——Research on the key technique of the front CPU in distributed Transmission Error testing system, is the further research and upgrade of the FMT system. In soft, abnegating bald Dos operating system, we will realize testing and displaying in real time on Windows operating system. In hardware, we use computer as postposition CPU, Monolithic Processor as front CPU, and link them into simple network. In this way, we will realize a kind of distributing testing system providing with high precision and remote controlled ability. There are many digital circuits in postposition system .In order to improve the system’s stability, Application Specific Integrated Circuit(ASIC) does for a lot of single components.The major theory characteristic of the system is a new view for pulse zoom and the method how to realize it by micro-computer.During the course of the research, we developed a new intelligent signal generator. It gave us a lot of help in debugging and self-check about the system.In the end of this thesis, the results of experiments and error curves are given.更多还原
