摘要 蓄电池的作用是把有限的电能储存起来，在合适的地方使用。线性光耦合器件TIL300可以有效地将测量通道与计算机系统隔离开来，对信号放大的线性度也很好。 The batterys role is limited to the energy stored in the right places. It worksby first turning electrical energy into chemical energy, into back when needed. Battery type are very many , at present the commonly used batterymainly is thelead-acid battery. The battery has many parameters, such as voltage, current, temperature, etc.. If these parameters are not within the normal range, it will affect battery life. Now along with the national economy rapid development, the electrical power system plays the more and more vital role, the battery unit was taking important constituent, its working condition quality affects directly the electrical power system security, reliable and the highly effective movement, therefore the battery monitor has the very vital significance. This monitoring system is based on Single chip microcomputer as the core,through the voltage gathering electric circuit and the temperature gathering electric circuit measured the voltage and the ambient temperature two parameters, and have the alarm circuit, when the parameter ultra time limit system may report to the police, the display circuit to display the measured parameters.In which linear light coupled apparatus TIL300 may survey effectively in the voltage gathering electric circuit the channel and the computer system isolates, moreover the linearity which enlarges to the signal very is also good. The temperature gathering electric circuit uses the widespread use digital temperature gathering chip DS18B20 presents to the accumulator cell the ambient temperature to carry on gathering. The alarm circuit uses the buzzer, the parameter ultra time limit it may report to the police. Display circuits used digital tube display, and with a professional driver to drive the digital pipe. Keywords: battery, single chip microcomputer, monitoring 摘要 I Abstract II 1 绪论 1 1.1 课题背景 1 1.2课题意义 2 2 蓄电池 3 2.1 蓄电池介绍 3 2.2 蓄电池分类 4 2.3 蓄电池发展
