摘要
插卡式预付费电能表系统由电能表模块、电卡模块、售电模块组成.采用AT89C51为CPU,专用芯片ADE7757计量电能,24C02芯片存储数据,并利用单片机技术处理其输出的数字信号,完成输入、显示、电卡数据读写等功能,实现电能表的自动化管理.
The card type prepaid energy meter system consists of the energy meter module, the electric card module and the electricity sold module. The CPU using AT89C51, the special-purpose chip ADE7757 measuring the electrical energy, saving data in the 24C02 chip. It uses microcontroller technology to process the digital signal output from such IC and completes the input, display, electric reading and writing of card data which achieves the automatic electric meter management.
