Ultra Narrow Band Technology Based FDMA Power Line Communication Technology of Long-Distance Meter Reading Solution for Distributed Users

本文基于超窄带FDMA电力线通信技术的研究和应用,对分散电力用户的抄表难题提出了经济适用的解决方案。国际上最新的超窄带技术(Ultra Narrow Band Technology)则解决了利用电力线进行远程通信的难题。该技术所选取的频率范围为555～1006Hz,从采集终端到站端数据处理单元(SPU)之间通过超低频电力线通信。因其载波频率低,信号可以穿越各种电压等级的变压器,直接到达变电站处理单元(SPU),实现终端到接收装置的一站式点到点通信,大大降低了系统复杂度,减少了线路铺设和施工成本,从而解决大范围远距离分散用户的集抄问题。

An economic solution is proposed for meter reading of distributed users according to research and application of Ultra Narrow band Technology Based FDMA power line communication technology. The ultra narrow band technology （UNBT） provides a way to communicate with power lines. The frequency range of UNBT is 555-1006 Hz. Data collected from meters is sent by UNBT to substation processing unit （SPU）. The point to point communication greatly reduces the complexity of the system, cuts the cost of communication line construction, and solves the problem of centrolized meter reading of wide-area, long-distance and distributed users.
