In recent years, companies step up the development of the fast lane: the completion of the production run has been an annual output of 150,000 tons of pig iron smelting companies; under construction, the modernization of 30,000 tons annual output of castings and machining parts auto parts company has advanced Vertical shot molding pressure, the level of sub-type microseism compaction modeling line, self-hardening resin sand molding line, dual power supply frequency melting furnace, sand automated treatment systems, as well as CNC machining centers and machining equipment production lines production equipment, with direct-reading spectrometer, casthouse Express analyzer, Coordinate measuring instrument, ultrasonic flaw detector such as the modernization of non-destructive testing equipment and a full range of conventional detection equipment; at the same time the company has a skilled use of CAD / CMD technology design, manufacturing, machining workforce and more than ten years such as day, love and respect their jobs, and accumulated rich experience in foundry staff.

近年来，公司步上了发展的快车道：建成了已投产运行的年产15万吨生铁的冶炼公司；正在建设的现代化的年产30000吨铸件和机加工件的汽车零部件公司拥有先进的垂直分型射压造型线、水平分型微震压实造型线、自硬树脂砂造型线、双供电中频熔化炉、自动化的砂处理系统以及加工中心和数控设备组成的机加工生产线等生产设备，拥有直读式光谱仪、炉前快速分析仪、三坐标测量仪、超声波无损探伤仪等现代化的检测设备和齐全的常规检测设备；同时公司拥有一支熟练运用CAD/CMD技术进行设计、制造、机械加工的员工队伍和十几年如一日、爱岗敬业、积累了丰富经验的铸造员工队伍。

The technology of electric information is developing very fast and make much more and more electric products teem,which develop in the direction of handy and miniaturization,such as mordern times communication equipmen、handy electric product、luggable computer、electric car、moonlet,and so on.it is used at large that the power supply make use of storage battery.hower most of storage battery can but use appropriative chargers,that need long time in the electrification and can't judge the electrification parameter and spare electrification time.thus it need a have much function and handy intelligent charger device that is a far-ranging application different kinds and types.the text integrate upwards request that will introduce a device and system of intelligent charger base on singlechip.in the power supply loop,the transformer take the voltage from 220v to 12v,then the rectifier circuit take the voltage turn to 14v,it is by way of the voltage of electrification power supply.

内容提要：电子信息技术的快速发展使得各种各样的电子产品不断涌现，并朝着便携和小型轻量化的趋势发展，现代通讯设备、便携式电子产品、笔记本电脑、电动汽车、小卫星等普遍使用蓄电池作为电源，应用非常广泛。然而大多数设备中的蓄电池，只能使用专用的充电器，而且普通的充电器大多充电时间长，无法判断其充电参数和剩余的充电时间，那么就需要一种广泛应用于不同种类和型号的可知道其充电参数和剩余充电时间的多功能便携式通用智能充电设备。本文结合以上要求介绍一种基于单片机的通用智能充电器的设计。

Chang and strong technical force, product development pressure from the clutch-industry team of experts chaired by the advanced production equipment, strict testing procedures, product quality through the "National Quality Supervision and Testing Center of motor vehicles" certification.
