而目前市場(chǎng)上出售的手機(jī)電池充電器,是只為單一手機(jī)電池充電的專用充電器,僅能對(duì)相應(yīng)的一種手機(jī)充電,而且每部充電器的價(jià)格在人民幣元左右,這就意味著,要配齊目前市場(chǎng)上出售的所有多種充電器,將是一筆較大的開(kāi)支。關(guān)鍵詞:手機(jī)充電器、智能、工單片機(jī)控制ABSTRACT One mobile telephone cell charger is necessarily to a mobile telephone intelligent charger on microcontroller can charge for all mobile telephone paper introduces the conition of mobile telephone cell the basis of analysis to the condition,this paper build a intelligent charger for all mobile telephone meet the requirement of mobile telephone cell,the author selects high performance hardware and designs stable and reliable hardware of the system is introduced detailedly including data acquisition circuit,control circuit,power supply,interface between the system and the people,the core of the system,is introduced more software design is mainly of the software system have been analyzed general aim of the software system is to realize reliability,stability,safety and the author designs the whole framework of the system with the thinking of software according to the objectoriented programming principles and technologies to implement the detailed design and coding. Keywords:moble telephone cell charger intelligent based on PIC16F877 40Pin FlashBased 8Bit CMOS Microcontroller課題背景隨著社會(huì)的快速發(fā)展,手機(jī)越來(lái)越成為人們生活中不可或缺的一部分。詳細(xì)介紹了系統(tǒng)的硬件組成,包括采樣電路、控制電路、電源、人機(jī)界面和單片機(jī)控制器,并對(duì)本充電器的核心器件—單片機(jī)進(jìn)行了較詳細(xì)的介紹。利用微電腦控制的智能手機(jī)充電器,可以對(duì)目前市面上所有的手機(jī)進(jìn)行充電。本文介紹了當(dāng)前手機(jī)充電器的發(fā)展現(xiàn)狀。重點(diǎn)闡述了系統(tǒng)的軟件設(shè)計(jì),首先對(duì)控制軟件進(jìn)行需求分析,總體目標(biāo)是實(shí)現(xiàn)系統(tǒng)的可靠性、穩(wěn)定性、安全性和經(jīng)濟(jì)性。如果某人的手機(jī)沒(méi)法使用,將對(duì)他的工作、生活造成巨大影響,甚至損失。另外,利用現(xiàn)有的手機(jī)電池充電器,過(guò)于分散,進(jìn)行有效管理的難度大,不適應(yīng)公共場(chǎng)所的需要。在去年產(chǎn)品質(zhì)量國(guó)家監(jiān)督抽查結(jié)果中,將近的廠家生產(chǎn)的充電器不合格。現(xiàn)在市場(chǎng)上發(fā)現(xiàn)有一些假冒偽劣手機(jī)電池便攜式充電器。這些假冒偽劣充電器由于設(shè)計(jì)簡(jiǎn)單,采用劣質(zhì)材料,加工手段粗糙,對(duì)手機(jī)電池的性能和壽命有很大損害。由于采用大電流的快速充電法,所以在電池充滿后如不及時(shí)停止會(huì)使電池發(fā)燙,過(guò)度的過(guò)充會(huì)嚴(yán)重?fù)p害電池的壽命。家生產(chǎn)的原裝旅行充電器和座式充電器,設(shè)計(jì)上都采用越來(lái)越精密的保護(hù)電路或開(kāi)關(guān)電路設(shè)計(jì),對(duì)電池的充電起到了良好的保護(hù)作用。雙槽形充電器除了具有慢速充電、快速充電、放電及鎳福、鎳氫電池兼充的標(biāo)準(zhǔn)功能外,還有部分產(chǎn)品帶有自動(dòng)溫度控制與電壓控制,嚴(yán)防過(guò)充的新功能,因而消費(fèi)者
