| 摘要: |
| 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。 |

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