文档介绍：1电子工程设计报告 1 摘要电子工程设计,是电子信息工程专业的一门综合性实训类课程,该课程将实际温度测量控制系统课题引入课堂。主要内容是进行模拟电路的设计与制作,包括线性电源的设计和制作,传感器信号调理电路的设计与制作,功率放大电路的设计与制作。本次电子工程设计课题为基于 51 单片机的自动温控调节系统。该系统通过温度传感器 AD590 将温度信号转化为电信号,运放调理电路将传感器转化的电信号调整为可以被 A/D 识别采集的电压信号,再经过 A/D 转换,转换成数字信号由单片机采集,数码管显示。本报告分为五章节,分别是温度测量控制总体概述、稳压电源的设计与实现、放大电路的设计与实现、功率放大电路的总体概述和体会感想,分别从实验目的、实验原理、原理图、 PCB 图、材料清单、焊接电路板、数据分析、调试问题和误差分析这几个方面分别说明。关键字: 电子工程设计线性电源传感器信号调理电路功率放大电路 Abstract Electronic Engineering Design prehensive and experimental course for undergraduate students major in electronic information and information engineering. The course aims at the design and product of analogous circuit, including the design and product of linear power supply, sensor signal condition circuit and power amplifier circuit. The electronic engineering design topic for automatic temperature control system based on51 single chip puter. The system through the temperature sensor AD590 temperature signals into electrical signals , Op-amp circuit adjust sensors into electrical signal to voltage signal can be identified by A/D acquisition, after A/D conversion, converted into digital signal collected by single-chip puter, digital tube display. This report is divided into five chapters, respectively is temperature measurement control in general, the design and implementation ofa regulated power supply, amplifier circuit, power amplification circuit design and realization of the general overview and understanding ofour feelings, respectively from the experiment purpose, the experiment principle, principle diagram and PCB diagram, bill of materials, welding circuit board, the problem of data analysis, debug and error analysis from several aspects, respectively.
