Abstract

The invention discloses a micropower wireless network self-organizing method and a micropower wireless network. The micropower wireless network self-organizing method comprises steps that a main node initiates a broadcast network-organizing command hop by hop in a common channel bank and performs data interaction with a sub node in a private channel bank; the main node, after collects a network-organizing beacon transmitted from a concentrator, acquires a node identifier and the time cost of a main node transfer message to a sub node within a first hop range and simultaneously carries out channel scanning and field intensity collection; and main node scans preset numbers and determines whether the numbers conflict, wherein the network is successfully organized if no numbers conflict. The method acquires the time cost reaching various sub nodes by automatically switching channel scanning and field intensity collection, performs collection computation by data in multiple fields so as to comprehensively take consideration in order to achieve fast network organization. The method increases efficiency of network organization to a great extent, shortens network-organizing time, and improves the stability of network communication.

Description

technical field [0001] The present invention relates to the technical field of micro-power wireless networks, in particular to a micro-power wireless network ad hoc networking method and a micro-power wireless network. Background technique [0002] With the expansion of the low-voltage power grid construction, the number of independent electric energy meters has increased. The traditional manual meter reading method consumes a lot of manpower, and the accuracy and real-time performance cannot be guaranteed. A large number of power line carrier communication meter reading methods are used on site. Due to noise interference and poor line quality, the reliability of communication is also facing huge challenges. Meter reading through micro-power wireless communication technology provides a better solution for low-voltage centralized reading, but point-to-point and point-to-multipoint micro-power wireless routing and networking methods have low efficiency and poor reliability. A...
