电池容量检测仪设计论文

你好，我是英语专业研究生，翻译摘要无数都已经通过。扣扣 nine five two eight five one one three one

楼主你好，这是翻译。。。This paper discusses various battery capacity test methods have advantages and disadvantages, in order to design the improvement of solar cell to measure the battery capacity. Principle of the research based on battery power in light conditions produce current, with the galvanometer recording current, relationship through the scientific method, derive the current and battery capacity. The battery capacity test instrument is simple, not high requirement on personnel; moreover, it can protect the battery from damage and other advantages, has good prospects for development. Keywords: solar battery; battery capacity.关键词： solar battery 太阳能电池 battery capacity 蓄电池容量望采纳，谢谢。。。

根据放电起始和放电终止两个电压，做线性处理得到容量，一般这个是最简单的，其它的都太麻烦。不用单片机，用数字电路，那就要选好芯片，配合运放的输出来做，多在网上找，找到了看不懂再问。

多功能充电器的硬件开发论文编号:JD781 包括任务书，开题报告，文献综述，外文翻译, 论文字数:14302,页数:29摘 要近年来，随着现代化工业的飞速发展，工业污染日趋严重，节能和环境保护己成为当今世人普遍关注的问题之一。研究低能耗、结构简单、操作简便的多功能充电器是未来发展的一大发展趋势。本文先介绍了多功能充电器开发的背景及意义，之后阐述了多功能能充电器的设计原理。通过4*4键盘可以输入所需充电的时间，在LED上实时显示剩余时间，同时采样充电器的实时电压并经A/D转换，单片机对输入的电压、电流信号进行比较，决定充电模式，通过D/A转换，控制输出信号，比较充电电源的电流、电压值给定，对充电电源电流进行控制，从而达到多功能充电的效果。通过对硬件和软件调试，基本能实现上述功能，具有较强的实用性。关键词：多功能充电器；单片机；蓄电池；A/D转换AbstractIn recent years, with the rapid development of modern industry, industrial pollution was worsening. Energy-saving and environmental protection had become one of the issues of common concern in the world today. Studying the multi-functional charger of low energy, simple structure, simple operating was a major trend of the development in the paper introduced the background and significance of multi-functional Charger firstly, and then introduced the design principle of the multi-functional charger. Through the 4*4 keyboard can input the required charging time, and display the remaining time in the LED, while sampling the real-time voltage of the charger and through the A/D converters, the MCU compared the importation voltage with the current signals, and charging into which mode ,through D/A conversion，controlled the output signal, analysis the given values of current and voltage with the Rechargeable power, and control the current of the charging power , so as to achieve the effect of multi-functional charger . Through the hardware and software debugging, achieved the above functions and the greater ：Multi-functional charger；Single chip microcomputer；Storage battery；A/D transformation目 录摘 要 IAbstract II目 录 III第1章 概 述 课题研究的背景及意义 国内外发展现状 本课题研究的内容 4第2章 充电器设计的基本理论 常用充电器的充电方式 多功能充电器的充电原理 7第3章 多功能充电器的硬件设计 电源回路 PWM控制 检测部分 模数转换芯片ADC0809 单片机AT89C51 模数转换芯片DAC0832 时钟电路 概述 寄存器 时间地址 实时时钟硬件接口原理图 LED显示部分 共阳极数码管工作原理 数码显示电路 键盘控制部分 工作原理 矩阵键盘简介 19第4章 硬件系统可靠性设计 电路系统设计 PCB板设计 硬件电路调试 22第5章 总结及展望 总结 展望 23参考文献 24致 谢 25以上回答来自:
