Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0025] see figure 1 , a micropower wireless meter reading method, comprising the following steps:

[0026] 1) When the central node of the concentrator starts meter reading, the main module of the concentrator starts to select a path for networking;

[0027] 2) When networking, the main module of the concentrator starts to select a certain route of the sub-node for networking. When the selected route is valid, it directly performs networking. When a certain route of the sub-node fails, the central node starts to target A child node performs path selection; that is, when the central node starts path selection for a certain child node due to a certain transaction.

[0028] 3) When the central node starts to select a path for a child node, the central node first judges whether there is an unex...

Abstract

The invention discloses a micro-power wireless meter reading method. 1) when the concentrator starts to read the meter, it selects a path for networking; If there is an unexplored path, it is judged whether there is a path that has been successfully explored in the last transaction related to the child node in these paths. If it does not exist, select the last used path and use this path to test If the node exists, select the path with the highest weight value that has not been tested, and use this path to test the node; 4) judge whether the test is successful, if the test is successful, then check whether the path used for this communication is saved in the routing table, has been If it is saved in the routing table, then update the weight of the path; if it is not saved in the routing table, then replace the path with the smallest weight in the routing table with this path; 5) If the path test succeeds, start routing meter reading. The automatic maintenance effect is good, and the wireless meter reading is realized.

Description

technical field [0001] The invention belongs to the micro-power wireless meter reading technology and relates to a micro-power wireless meter reading method. Background technique [0002] With the rapid development of scientific application technology, in the field of electric meter reading, there have been a variety of meter reading schemes coexisting, such as traditional manual meter reading, leased telephone line meter reading, low-voltage power carrier meter reading, optical fiber meter reading, etc. But these meter reading methods all have their own defects. The traditional way of meter reading is to manually copy the energy meter data from door to door, which will inevitably lead to inaccurate statistical data and cannot truly reflect the electricity consumption of users; it is difficult to standardize the operation, resulting in increased unknown losses; and it consumes a lot of labor, high cost and low efficiency . Obviously, the manual meter reading management mod...
