摘要：為了減少電能收費(fèi)管理中人力、物力的浪費(fèi)，減少不安全因素，本文進(jìn)行了智能IC電能表設(shè)計(jì)研究，通過多種技術(shù)手段，降低了儀表的功耗，提高了儀表的測量精度，使儀表具有較高的可靠性，科學(xué)地計(jì)算用電量，為用電用戶與供電公司之間提供了準(zhǔn)確的收費(fèi)依據(jù)；智能電能表具備預(yù)付費(fèi)功能和密碼保護(hù)功能，從根本上解決了供電公司收費(fèi)難的問題。
IC卡的使用與其應(yīng)用系統(tǒng)是密切相關(guān)的。一方面，采用IC卡可以使系統(tǒng)的運(yùn)作更富創(chuàng)造性；另一方面，應(yīng)用系統(tǒng)會不斷地對IC卡提出新的要求，促使其功能更加完善。因此．怎樣把IC卡與實(shí)際應(yīng)用有機(jī)地結(jié)合起來。充分發(fā)揮IC卡的優(yōu)越性，一直是IC卡技術(shù)的一個(gè)重要課題。智能IC卡電能表就是IC卡技術(shù)的一種實(shí)際應(yīng)用。
智能IC卡電能表是將電能表的機(jī)芯和高水平的測控電路集成在一個(gè)整體的表殼內(nèi)，既保持了計(jì)量精度，又具備了電表運(yùn)行狀態(tài)的自動化管理功能。同時(shí)能杜絕人為破壞系統(tǒng)和私自開啟IC卡控制系統(tǒng)導(dǎo)致的控制失靈行為。

 Electric instrument intelligent management installment design

Abstract: In order to reduce in the electrical energy charge management the manpower, the physical resource waste, reduced the unsafe factor, this article has conducted the intelligent IC electrical energy table design research, through many kinds of technological means that reduced measuring appliance's power loss, increased measuring appliance's measuring accuracy. Enables the measuring appliance to have the high reliability. Calculates the electricity consumption scientifically, has provided the accurate charge basis for between the using electricity user and the Electric power company; The intelligent electrical energy table has the pre-payment function and the password protection function, fundamentally has solved the problem which the Electric power company receives makes an effort.
The IC card's use and its application system are close related. At the same time, uses the IC card to be possible to cause system's operation richer creativity; On the other hand. The application system unceasingly will also set the new request to the IC card. Urges its function to be more perfect. Therefore. How organically unifies the IC card and the practical application. Displays the IC card fully the superiority. Has been a IC card technology important topic. The intelligent IC card electrical energy table is the IC card technology one kind of practical application.
The intelligent IC card electrical energy table is the traditional electrical energy table cassette mechanism and the high level observation electric circuit integration in an overall watch case, also maintained the measuring accuracy. Also has had the instrument running status automated management function. Simultaneously can cease the artificial destruction system and open the control malfunction behavior which secretly the IC card control system causes.
