Problems solved by technology

However, the existing routing algorithm is only based on the principle of "field strength priority" or "level priority". If it relies on "field strength priority", the path level selected by this method may not be the simplest. However, there may be longer data transmission time due to the more complicated layers, which cannot meet

Embodiment Construction

[0021] The following description will be made in conjunction with the accompanying drawings and specific implementation manners.

[0022] see figure 1 , figure 1 It is a structural schematic diagram of an embodiment of the micropower wireless communication system of the present invention. In this embodiment, the micropower wireless communication system includes a master node 110 and at least two slave nodes 120 . Wherein, the master node 110 can realize ad hoc network with the slave node 120 as a router, and two-way communication can be realized between the master node 110 and the slave node 120, and the slave node 120 can be used as a relay node to forward data frames to the master node 110, In order to realize the communication between the master node 110 and the slave node 120 outside the direct wireless communication distance of the master node 110, generally, according to the distance from the master node 110, the slave nodes 120 are divided into levels, from near to fa...

Abstract

The invention provides a micro-power wireless networking and communication method, a master node and a system. The method is mainly applied to a communication system consisting of a master node and at least two slave nodes, and comprises the following steps: acquiring neighbor field intensity information tables of the at least two slave nodes by using the master node; traversing all paths ranging from the master node to each slave node according to the neighbor field intensity information tables; calculating the route weight value W of each path ranging from the master node to the slave nodes according to a formula; saving all paths ranging from the master node to the slave nodes and the route weight values W of the paths, which are taken as route information of the slave nodes, in a route table, and transmitting the route information of the slave nodes, which is taken as configuration parameters, to the slave nodes. Through the way, the communication instantaneity can be ensured, and the communication success rate can be increased.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a micro-power wireless networking, a communication method, a master node and a system. Background technique [0002] According to the overall requirements of the State Grid's strong and smart grid construction, gradually realize the overall goal of "full coverage, full collection, and full cost control" in the construction of power user information collection systems. The micro-power wireless self-organizing network can realize low-voltage power user electricity information Convergence, transmission, interaction, and the location of the terminal equipment is fixed, and the communication link is relatively stable, effectively solving the problem of inability to communicate between nodes, safe, stable, and reliable, greatly improving the success rate of meter reading and reducing the chance of staff going to the site for maintenance , saving a lot of manpower and material reso...
