【摘要】 本文主要论述口径30～155mm炮弹内径尺寸非接触式光电测量系统。 基于光三角测量原理，文章重点研究了采用光电位置传感器(PSD)进行内径尺寸弱信号检测的方法。系统设计为主从式两级微处理器控制结构。主控制器完成管理、通信及光栅位移、角位移测量控制功能；子控制器完成PSD内径尺寸检测、串行A/D模数转换及数字信号处理器(DSP)数据处理功能。被测炮弹内径的测量值，最后送入以AVR高速嵌入式单片机为核心的主控制器的数据存储器中并显示。在测量的过程中，通过键盘实现人机对话。更多还原

【Abstract】 The thesis is mainly about the noncontact photo-electronic measuring system of inner diameter of the shells whose calibers are from 30mm to 155mm.On the basis of optical triangulation measuring principle, the emphasis of the thesis is to investigate the weak signal measuring method of inner diameter employing the PSD. The system is of the controlling structure of subordinate two-poles microprocessor. The main controller is in charge of managing, communicating and the measuring of grating-displacement and angle-displacement. The subcontrollcr is in charge of the measuring of inner diameter of PSD, the analog-to-digital converting of the serial A/D and the data processing of DSP. The value of the shells inner diameter is sent into the data memory of the main controller whose core is the AVR high-speed embedded single-chip microcomputer and is displayed at last. During the course of measuring, the dialogue between the human being and the computer can be realized by the keyboard.更多还原
