自动抄表的低功耗无线网络设计与实现

A low power wireless mesh network for auto meter reading

由于近些年来智能电网的大力发展需求出现了各种自动抄表系统的应用方案,但各有不足之处未能真正在我国广泛采用。为了实现智能电网自动抄表系统的真正应用,设计了一种易于实现的、网络开销小并低功耗的无线网络,它采用ARM和MCU作为自动抄表系统的无线集中器硬件平台,并搭配Sub-GHz的射频收发模块,集中器与节点设备之间采用自定义协议的自动组网形式,可实现50个节点自动灵活组网,而且网络开销小只占用4 k存储空间。整个系统具有实用性和应用性强的特点。

In recent years due to the great needs of smart grid development a variety of automatic meter reading system application solution appeared, but all have some defects to practical application in our country. In order to realize intelligent power network automatic meter reading system in the real application, the paper designs a easy implementation, little overhead and low power wireless network, it Uses ARM and MCU as the automatic meter reading system wireless concentrator hardware platform, and with Sub-GHZ RF transceiver module. Concentrator and 50 nodes can automatically organize wireless network. And the protocol stack only occupies 4k storage space. The whole system is good at practicability.
