Problems solved by technology
This type of algorithm is inflexible in dealing with variable factors, and often ignores the correlation between relay paths and communication channels, cannot quickly adapt to sudden changes in the environment, and is easy to discard effective paths that fail due to accidental factors, and replace them too frequently. path, resulting in longer and longer meter reading links and lower efficiency

Embodiment Construction
[0043] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.
[0044] Any feature disclosed in this specification (including any appended claims, abstract), unless otherwise stated, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.
[0045] Such as figure 1 Shown, the detailed steps of the meter reading stage of the present invention are as follows:
[0046] 1) Start reading the slave node, set the effective time of the meter reading task to 30 seconds, and enter the S1 master-parent node stage by default. Use the relay link meter reading obtained from the main parent node of the target slave node; if a single reading fails, try repeatedly in each channel of the current channel group; if the r...

The invention provides a concentrator initiative meter-reading routing method suitable for variable factors. The method comprises the following steps: a router collects neighbor field intensity of all slave nodes through a networking process, and configures the slave nodes to a specific private channel bank; the router sets a meter-reading attribute for each meter-reading for each slave node, and selects a relay path and a communication channel to send a wireless meter-reading data frame according to different strategies in accordance with the difference of various meter-reading attributes; an available path in the networking process is preferably selected to supplement a theoretical path acquired by use of the shortest path algorithm, and the theory is combined with the actuality. By use of the method provided by the invention, the influence of various accidental factors to the meter-reading in the actual application is sufficiently considered, a communication channel attempts to reading meter repeatedly through different relay paths; the successful rate of each meter-reading task and the network stability are guaranteed while reducing the interference to the adjacent zone area.
Description
technical field [0001] The invention relates to the field of micro-power wireless communication technology and routing technology, in particular to a concentrator active meter reading routing method adaptable to changeable factors. Background technique [0002] At present, the construction of smart grid is proceeding in a standardized and orderly manner. In terms of the communication mode of the power user information collection system, the micro-power wireless self-organizing network has already exceeded tens of millions of application nodes, and has been upgraded to the micro-power wireless interconnection standard. The efficiency of routing meter reading based on micro-power wireless is an important factor affecting the success of this network. [0003] In the actual long-term application, the efficiency of routing meter reading is affected by various environmental factors: small impacts such as individual meter failures, changes in individual location ground features; la...
