Abstract
This paper introduces the IC card table and the classification of the modes of operation and management. there are also several charges meter reading management model for the analysis parison, given in several meter-reading mode use IC card technology more suitable for China's national conditions conclusions, Meanwhile IC card technology to the development described
Based on low-power, high-performance production ATMEL Corporation AT89C2051 as the core, coupled with ADI's high-precision measurement of electricity chip ADE7755. AT88SC102 cards and cards and other external circuit design of IC card charges meter control system, The controlling system of the prepaid electrodynamic meter with 1C bines hardware and software knowledge and plishes consumption of the electrodynamic meter terminal with IC card through assembly language system's main content involves the base knowledge of the IC card,the hardware chooses to use with design, system of the hardware primarily to analyze with the function;The main procedure,the IC card break-sub-procedure,the customer card sub- procedure, the pulse break-sub-procedure and the display-sub- procedure data system in consumption and stability is optinal effect through selection card's security with data is enhanced through programming in reason.
This paper jamming on the classification and power meter IC card software and hardware anti-jamming technology are discussed .
Key words: IC card, the electrodynamic meter,
