摘要
为了满足人们对于智能化电能表的需求,采用嵌入式技术和射频识别技术相结合,从硬件和软件方面对电能表和射频接口进行设计并予以工程实现。电能采集利用高性能的ADE7755,微控制器采用低功耗的MSP430单片机,射频读写采用低成本的MF RC500,并采取多种抗干扰方法进行优化设计。试验表明,电能表具有多功能、低功耗及抄表方便快捷等特点,具有一定的市场前景。
To meet the intellectualized demand of people,the watt-hour meter is designed and realized from hardware to software as a project. The embedded technology and RFID technology are also unified. ADE7755 is taken as an electrical energy measurement chip. MSP430 is taken as a MCU. MF RC500 is taken as a RF interface module chip. Various antiinterference methods are applied. It is multifunctional,low-power and convenient in practice,and it is worth of generalization and application.
