摘　　要：分析现有抄表系统存在的不足,介绍基于短距无线通信与3G的无线集中抄表系统。结合短距无线通信与3G技术,数据的汇聚与转发均通过无线方式进行。将采集到的计量表数据通过3G网络转发到计费部门的数据管理中心。与现有的抄表系统相比,该系统具有布置灵活、抄表范围大、功耗低、实时性好、干扰小等特点,在实际应用中有较好效果。This paper analyzes the shortcomings of existing meter reading systems, proposes a wireless centralized meter reading system based on short distance wireless communication and 3G. The system combines the short distance wireless communication and 3G technology together with the data＇s collection and transmission through a wireless manner. The collected data of meter are transmitted through the 3G network to the billing department of the data management center. When compared with existing meter reading systems, this system has a more flexible layout, larger coverage, lower power consumption, higher real-time features, less interference and gets better results in practical application.
