摘 要
电源广泛用于各种电子设备中，其好坏直接影响着电气设备或控制系统的工作性能。而电源对其参数要求非常苛刻，电源的过压过流以及温湿度对电源的寿命影响很大，过电压电流有可能烧毁电源中的功率管，温度太高导致热量散发不出去也会给电源带来损坏，为保证电源有一个可靠的运行环境，需要对电源的温湿度，电压电流进行实时监控，当参数超标应该能够报警提醒用户。
基于单片机的蓄电池温度检测系统广泛运用了计算机、自动测试、微电子和自动控制等多项技术，不仅具有信号采集方便、简单和灵活性大等优点，而且可以大幅提高被测参数的技术指标。
基于单片机的优良特点特设计了一个以单片机为核心的电源参数管理系统，对电源及蓄电池的温湿度和电压电流以及功率实时检测并通过可视化液晶显示出来，当电源的其中一项参数超过其所能承受的最大限度时给予用户以提示报警，从而很好的保护了电源，提高了寿命，本设计具有体积小、成本低、实时性好等特点。

Abstract
Power is widely used in various kinds of electronic equipment, the direct impact on the electrical equipment or control systems work. And the power of its parameters requirements of very demanding, the power flow and temperature and humidity on overpressure influence of life, the power supply voltage current likely burned the power tube, high temperature cause quantity of heat to send out not go out will also give power to bring damage, to ensure a reliable power supply for power operation environment of temperature and humidity, need, voltage current real-time monitoring when the parameter overweight should be able to alarm remind users.
Based on SCM battery temperature testing system widely used the computer, automatic test, microelectronics and automatic control etc. Several technology, not only has the signal acquisition convenient, simple and flexible, and advantages of tested parameters can greatly improve the technical indexes.
Based on SCM admirable characteristic designs especially a based on singlechip power supply parameters management system, the power and the battery voltage and temperature and humidity and real-time detection and power through a visual LCD display, when the power supply one parameter to withstand more than its maximum to tip alarm when giving users, thus well protected the power, improving the life, this design has small volume, low cost and good real-time etc. Characteristics.
Key word: power supply parameters, detection, storage battery state
