摘要 蓄电池是电池中的一种，它的作用是能把有限的电能储存起来，在合适的地方使用。它的工作原理就是把化学能转化为电能。它用填满海绵状的铅板作负极，填满二氧化铅的铅板作正极，并用22～28％的稀硫酸作电解质。在充电时，电能转化为化学能，放电时化学能又转化为电能。Abstract Energy can be changed in various forms of energy, one of them, the chemical energy into electrical energy conversion device called chemical batteries, the general referred to as batteries, battery cells and batteries are the original division. Discharge can not be used after the manner of charging the internal regeneration of active substances called primary cells, also known as a one-time battery. Can be used after discharge rechargeable internal activity of the establishment of renewable material, the energy stored as chemical energy, the need to discharge the chemical energy to electrical energy is converted to the battery, called the battery, also known as secondary batteries. The lead-acid storage battery group is the drive power supply or contingency power supply for many machines. So the performance of the storage battery group is directly related to the normal running of many device. It is necessary to measure batteries’ parameters accurately and frequently in order to enhance their lives. The monitor system is to take AT89S52 as the core, its chip adopt the craft of CMOS and faces to monolithic machine with memory structure. It implies the quick cleaning of the 8 inside the break source. The programmable string goes to weave, still having the spare time and dropping to give or get an electric shock the way. Its integrated degree is high, the speed is quick the power consumed is low specially suitable for the control system of many methods, data collection. This system can measure 10 roads or 20 roads the electric voltage of electric current etc. Key words: single-chip computer; battery; detection.目录 1 绪论 1 1.1 概述 1 1.2 课题的意义 2 1.3蓄电池的发展现状 3 2.蓄电池检测系统总体设计 5 2.1 蓄电池的工作原理 5 2.2 当前蓄电池的主要检测方法 5 2.3 铅酸蓄电池检测系统 6 2.4系统框图 6 3系统硬件设计 8 3.1器件选择 8 3.2主控单片机AT89S52 8 3.3 AD转换器件TLC549 11 3.4电压采集部分 12 3.5电流采集电路设计 14 3.6温度采集电路设计 1
