Network Routing Method for Power Wireless Data Acquisition

Abstract

The invention provides an electricity wireless data acquisition network routing algorithm. The algorithm comprises the following steps: S1, stopping beacon forwarding, and starting routing computing; S2, judging whether a standby routing is existent, if the standby routing is existent, collecting a field intensity table of a slave node by use of the standby routing, and collecting a field intensity field of an adjacent node of a center node according to a center node neighbor table, if the standby routing is nonexistent, directly collecting the field intensity table of the adjacent node of the center node according to the center node neighbor table; S3, collecting field intensity tables of other slave nodes according to the collected neighbor table of the slave node; S4, judging whether the collection is finished, performing the routing traversal computing from the height of the global network if the collection is finished, or returning to step S3 if the collection is unfinished; S5, reserving multiple routings with the highest weights according to a priority rule; S6, judging whether the computing is finished, distributing the hierarchy according to the routing of each slave node if the computing is finished, or returning to step S4 if the computing is unfinished; S7, distributing time slots; and S8, configuring network routing information of all slave nodes to finish the routing computing. Through the adoption of the method provided by the invention, the network success rate can be improved.

Description

technical field [0001] The invention relates to the field of wireless data collection of smart electric meters, in particular to a network routing method for electric power wireless data collection. Background technique [0002] In 2013, the State Grid Corporation of China issued Q / GDW 11016-2013 "Communication Protocol for Electric Power User Information Collection System Part 4: Data Transmission Protocol Based on Micropower Wireless Communication". This standard clarifies the networking process framework of the wireless acquisition network, and provides some routing methods for reference. The routing methods provided are common routing methods, such as figure 1 As shown, there are many defects in it, including: (1) Using layer-by-layer collection of neighbor field strength tables and layer-by-layer configuration of the slave node network, this algorithm discards routes whose signal field strength does not meet the standard at the beginning, These nodes whose signal stren...
