公网无信号区域远程抄表问题解决方案

On the Solution to the Problem of Remote Meter Reading in Public Network Without Signal Area

随着计量自动化系统的逐步完善,电网全用户表码信息采集成为系统数据得以深化应用的重要基础。利用无线公网通信是目前实现远程抄表的主要手段之一,但仍存在公网难以覆盖的偏远山区、公网信号屏蔽地下室或弱信号区域,无法实现远程抄表,无公网信号问题成为解决远程抄表的首要难题。列举了4种解决无信号区域远程抄表解决方案,详细对比说明各技术特点,供专业人员参考、借鉴,达到解决实际抄表问题的目的。

With the gradual improvement of the metering automation system,the acquisition of grid users’table code information is an important basis for the further application of system data.At present,wireless public network communication is one of the main means to achieve remote meter reading.However,there are still remote mountainous areas,basements or weak signal areas that are difficult to be covered by public network,so it is impossible to achieve remote meter reading.This paper describes and lists four solutions for remote meter reading in non-signal areas,and compares and illustrates the technical features in detail for the reference of professionals,so as to solve the problem of actual meter reading.
