一种电子货架标签系统（ESLS）的设计

针对目前商业领域纸质标签的信息更新滞后、手工更换效率低、易出错等缺点，采用自顶向下设计方法设计了一种基于有源远距离RFID技术的电子货架标签系统。该设计集计算机控制、远程收发、微功耗设计特性为一体，辅以完善的应用系统设计。该系统业务管理方便，信号覆盖范围可扩展，标签显示模块的电池寿命可达3～5年，具有普遍应用意义和广泛应用前景。

Design of an Electronic Shelf Label System(ESLS)

In order to overcome the weakness of low efficiency, lag and high fault probability in updating information with paper labels in commercial fields at present, an electronic shelf label system(ESLS) is designed based on long-range active RFID technology with the top-down design method. In this design,computer controlling, remote trans-receiving, super-low power dissipation designs are integrated together with perfect design of applied system. The system is featured by convenient business management, expandable signal covering, and the lifetime of battery for display module of the ESL is about 3 to 5 years. Therefore it has pervasive significance and extensive spectacle of applications.
