蓄电池充电器设计 作者姓名：胡益民 专业班级：2012060504 指导教师：李铁、张晴 摘要 随着现代科学技术水平的不断提高，微型处理器技术已经广泛应用于生活中的方方面面，利用微型处理器制作一款针对多种铅酸蓄电池充电的多功能充电器已经成为了可能。在生产生活中我们常会使用到各种型号的蓄电池，如果每种蓄电池都需要一个不同的充电器，这不仅使用时相当麻烦而且会浪费空间和金钱。该充电器以AT59c52单片机为核心，使用ADC0809为AD转换模块智能判断被充电蓄电池型号，然后控制电路输出，以恒压充电的方式对相应的蓄电池充电，可以满足12V10Ah、24V10Ah、36V12Ah、48V20Ah铅酸蓄电池的充电需求。使用此款多功能充电器不仅免去了购买和使用多种充电器的麻烦,而且减少了购买多种充电器的花费，所以该充电器有较高的商用价值，值得开发和使用。 本次设计首先对充电技术和充电技术的发展做了探讨，然后进行了对方案的讨论与确立，之后设计电路图，确立了电路图后开始购买电路中所需零配件来制作实物，最后进行的是编写程序和调试。 关键词：多功能充电器； AT89c52单片机； ADC0809；恒压充电 Design of battery charger Abstract: With the continuous improvement of the modern scientific and technological level, micro processor technology has been widely used in all aspects of life, using micro processor making a variety of lead-acid battery charging of the multifunctional charger has become possible. In industry and life, we often use a variety of models of the battery, if each battery needs to be a different charger, which is not only used in trouble and will waste space and money. The charger in order to AT59c52 as the core, using ADC0809 for AD conversion module intelligent judgment is charged battery type, then the control output circuit, with constant voltage charging of battery charging, can meet 12v10ah, 24V10Ah, 36v12ah, 48V20Ah lead-acid battery’s charge power demand. Using the multi-function charger not only eliminates the purchase and use of a variety of charger of trouble but also reduce the purchase cost of a variety of charger. So the charger had partly commercial value, it is worth developing and using. This design firstly did the study of charging technology and its development , then had carried on the discussion to the plan and established it , next designed circuit diagram by proteus8.0, I began to buy circuit required spare parts to make real after circuit diagram established, writing the program and debugging as the last process . Key words: multifunctional charger; AT89c52 MCU; ADC0809; constant voltage charging 目录 第1章 前言 1
