Abstract

The invention relates to an IPv6 micro-power wireless communication method. The method comprises the steps of (1) starting micro-power wireless automatic networking according to a configuration instruction of a main meter reading module of a concentrator, and sending a meter reading instruction; (2) determining the quantity of target IP addresses; (3) finding out target routes of the plurality of target IP addresses, creating a multi-cast meter reading downlink instruction frame of one network layer, and distributing; (4) receiving the downlink multi-case meter reading instruction through a terminal module sending the instruction application, and determining whether the multicast downlink instruction frame is processed; (5) comparing the target IP addresses in the downlink instruction frame with the target IP address through a micro-power wireless communication module, and determining whether to send a multi-cast meter reading stopping instruction; (6) determining whether an energy meter response frame is received before exceeding the time; if so, performing the multi-cast meter reading uplink instruction, and sending the energy meter response data to the concentrator.

Description

technical field [0001] The invention relates to a wireless communication method, in particular to an IPv6 micro-power wireless communication method. Background technique [0002] With the in-depth promotion of smart grids in the country, the requirements for data collection and transmission methods for power management are getting higher and higher. Due to the large number of end users in the power industry and the complex on-site environment, the traditional meter reading mode can no longer meet the demand. The automatic meter reading currently used mainly includes wireless public network GPRS meter reading, power line carrier meter reading, micro-power wireless ad hoc network meter reading, etc. The use of micro-power wireless mode can realize cross-voltage level and cross-region meter reading; at the same time, due to the fast transmission rate (data transmission rate can reach 37600bit / s), high real-time performance, it can provide stronger communication capabilities fo...
