基于嵌入式系统的铅酸蓄电池充电控制器设计
绪论
铅酸蓄电池作为一种可重复使用的储能设备得到了广泛的应用,但是充电一直是影响其使用寿命的关键问题。因此,本文致力于研究并设计一种快速、安全、智能的蓄电池充电控制器。
本文根据充电系统的功能要求和技术指标,进行了总体方案设计。蓄电池充电控制器的控制方式采用基于时下最常用的嵌入式 ARM7 微处理器LPC2292的数字控制。充电系统采用多模式充电控制策略,分别为激活充电、大电流快速充电、过充电和浮充电四种模式。根据充电系统的总体方案,对充电控制器的硬件和软件进行了详细的设计与实现。硬件部分主要充电控制器的驱动电路,采样电路,保护电路以及辅助电源的设计。软件部分主要包括介绍了μC/OS -II 实时操作系统在ARM7上的移植和各个软件模块包括A/D 采样、控制器数据的处理以及数据在LCD 显示等程序的实现。

ABSTRACT
As a reusable energy storage device to the lead-acid battery has been widely used, but the charge has been a key issue is the impact of its useful life. Therefore, this paper mitted to research and design a fast, safe, smart battery charge controller.
According to the charging system functional requirements and technical specifications, the design of the overall program. Battery charge controller control among the monly used embedded ARM7 microprocessor LPC2292-based digital control; charging system using multi-mode charging control strategy, were activated charging, high-current fast charge, over-charge and floating charge four mode. According to the general scheme of the charging system, a detailed design and implementation of the hardware and software of the charge controller. The hardware part of the main charge of the driving circuit of the controller, the sampling circuit, the protection circuit and an auxiliary power supply design. The software part includes ARM7 transplant of μC / OS-II real-time operating system and software modules, including the A / D sampling, the controller data processing and data in the LCD display program realization.
Keywords: embedded; lead-acid batteries; charge controller; LPC2292
