This paper application of IC card unit, 89 c51, LED displays, and other units to plete the rate calculation, data display, alarm, intelligent electric meter to realize. And according to the ladder electricity price to calculate the surplus electricity, and so on and so forth, inside of the card, to simulate the automatic alarm function with a buzzer and implementation by four keyboard display switch and electricity price adjustment function, using Siemens SLE4442 card IC card, which can realize the logical encryption, can be repeatedly read and write, Kane data confidentiality. Keywords: Intelligent electric meter。89C51。Electricity measurement. 南昌工程學(xué)院本科畢業(yè)設(shè)計 (論文 ) 目 錄 摘 要 ...................................................................................................................................
