【正文】 考文獻(xiàn) 22摘 要隨著社會(huì)發(fā)展、經(jīng)濟(jì)水平的逐漸提升,人均用電量大幅度增加使得“一戶一表制”得到大面積推廣,對(duì)電能表的要求和需求大幅度增加。為鼓勵(lì)用戶在低谷時(shí)段用電,緩解用電緊張,電力部門已試行峰谷不同電價(jià)的計(jì)費(fèi)辦法,同時(shí)采用智能化遠(yuǎn)程抄表、自動(dòng)計(jì)量計(jì)費(fèi)等方法以解決人工抄表存在的諸多問題,減輕勞動(dòng)強(qiáng)度,提高管理水平。關(guān)鍵詞:復(fù)費(fèi)率、電能表、CS5463單片機(jī)、通信接口AbstractWith the development of society, economy level of electricity per capita increased greatly increased, which is one household system get a list of widespread, the electric requirements and demand increased substantially. To encourage users in the downturn, relieve electricity tense period, electricity the power sector has trial peak and valley of charging method, different price by adopting intelligent remote meter, automatic measurement methods to solve charged artificial meter reading, there are many problems, reduce labor intensity and raise the level of management. Microputer concentration meter reading management system is an ideal solution is based on the power sector, according to the multifunction watthour meter technical conditions and munication protocols designed with munication interface and timeshare billing function, and electronic reply fee rate watthour meter with traditional inductive watthour meter on its structure and principle of the restriction, usually exist measurement range small, poor stability, low accuracy faults and cannot meet the demand of social development. As microelectronics technology and MCU development and popularization, new intelligent measurement and control technology rapid development, based on singlechip) phase watthour meter shows its obvious advantage. This instrument is highperformance micro controller as the controller chips for measuring control points of new intelligent measuring meters, has charged of period of time of continuous measure function, and the purpose of electricity can achieve plan.Keywords: reply fee rate, electric energy meter, CS5463 singlechip microputer and munication interface引 言電能是社會(huì)生產(chǎn)、人民生活所必須的最重要的能源之一。隨著國(guó)民經(jīng)濟(jì)的迅速發(fā)展和人民生活水平的極大提高,這種矛盾日益加劇。據(jù)有關(guān)專家論證:全國(guó)在不新增裝機(jī)容量的情況下,只要采取分時(shí)計(jì)費(fèi)的方法加強(qiáng)用電管理,合理用電,就能開發(fā)出60%的電力潛能。推行峰谷分時(shí)電價(jià)的前提是使用新型的復(fù)費(fèi)率的電能表。電能表已從單一功能的電能計(jì)量向多功能化發(fā)展。一、電路工作原理本設(shè)計(jì)采用開關(guān)穩(wěn)壓電源,將220 V交流市電整流穩(wěn)壓為模擬、數(shù)字兩路+5 V電壓,為整個(gè)電表電路供電。
