【摘要】 本文在课题组自行研制的ＥＭＣＤ－ Ⅲ误差测控仪上开发了实时测控系统及其配套软件－ 为实现Ｗｉｎｄｏｗｓ 下控制，研制了底层接口板采用ＡＴ８９Ｃ２０５１ 芯片，用专用汇编语言控制驱动电机和光栅尺、编码盘的计数，并通过微机的ＩＳＡ 总线实现通信，在微机上设计Ｃ 语言接口，提供控制的基本函数；高层以ＶＣ＋ ＋５－０ 为开发工具，完成界面及误差数据的采集、控制、分析和处理过程－更多还原

【Abstract】 The system developed in the thesis for real-time measurement and control as well as the software has been tested on EMCD-Ⅲ (Error Measurement and Control Device) developed by the research group. In order to realize control under Windows, low lever interface board is consisted of AT89C2051 chips which control drive motor and count linear grating, encoder with special assembler. The communication is realized by ISA bus and C language interface and the basic function of control are provided on microcomputer. Upper lever is developed by VC++5 0 under which interface and acquisition, control, analysis, processing of error data have been finished.更多还原
