摘　　要：长期以来,三表数据抄送问题都是相关供应部门非常想解决但又得不到切实解决的问题。在行业信息化过程之中,户表数据的自动化抄送具有非常重大的意义,因为户表数据是相关行业销售过程中最原始的数据,这个数据的准确度和及时性直接影响了行业内部其他信息化水平。目前使用的基于无线数传模块的抄表系统都是采用单跳的通信方式,由于射频芯片发射功率的限制,其覆盖范围有限,会出现许多盲点。本文在单跳方式的基础上,提出了一种自动搜索的寻的算法,通过中继的转发来实现多跳,扩大覆盖范围。For a long time,how to read meters＇ data is a question that the government wants to solve quickly. Automatic meter reading system is very important because it＇s the original data. The data which is exact and timely is very important. For the moment,automatic meter reading system based on wireless RF chip all use one jump communication. For its limited send power,the covered area is very limited so that there are many blind spot. This article is based on multi -jump communication and via relay to spread the covered area.
