为取代传统的纸质货架标签，提出一种低功耗的双模态电子货架标签系统。该系统基于物联网和无线传感器网络技术，针对低功耗目标，采用电泳式电子纸与蓝牙模块分别作为显示与通信模块。并将标签的运行状态分为工作与休眠两种状态，使其按照服务器指令按时切换运行状态，在满足低功耗的前提下实现标签状态汇报、内容更新等功能。从实验数据可见，该系统能基本满足应用场合的功能需求，相对传统的纸质标签具有明显的营运成本优势。

To replace traditional paper shelf labels , it proposes a power efficient bimodal electronic shelf label system , based on the technologies of the Internet of Things and wireless sensor networks .Focusing on the power efficiency , the proposed electronic shelf label adopts an electrophoretic electronic paper dis-play and a Bluetooth module as the display and communication modules respectively .Moreover , this la-bel has two working states: wake-up state and sleep state , enabling it to switch the working state under the server commands , to report label status , and to update display contents with low power consumption . The experimental results show that this system can meet the basic requirements of application scenarios . It has an advantage of comparatively low running costs over traditional paper labels .
