自动抄表系统的无线抄表路由设计

utomatic meter reading system can solve the problems of manual meter reading,such as inefficiency,miss-reading,wrong-reading and late statistic.It is one important part of the smart electric net project in China.The wireless meter reading protocol is key point of automatic meter reading system. In this paper,one wireless routing protocol for reading meter is proposed after DSR is studied,according to the characteristics of meter reading network.In this routing protocol,one mechanism called broadcasting according to the increasing of TTL gradually and one load balancing mechanism are adopted.The former can reduce the overhead of the route discovery and the latter can increase the thuoughput of the meter reading network.
