摘　　要：介绍了POCSAG编码协议、FLEX编码协议和基于无线唤醒功能模式下的工作原理,并通过对这些工作模式下的功耗计算和比较,分析了各种方法的优缺点以及节电情况;结合无源射频标签工作原理,提出了一种适用于干电池供电系统的新型节省功耗设计方案。分析结果表明使用无源唤醒功能的无线通信设备电池使用寿命延长到年以上。The operational principle of POCSAG code protocol, FLEX code protocol and device based on waked - up function are introduced. Through calculating and analyzing three working models, the advantages, disadvantages and power consumption of these methods are compared with each other. Finally, according to the principle of passive RF - tag, a new ultralow consumption design scheme is presented which is applicable to battery of system power supply.
