Embodiment 1

[0028] Embodiment 1 of the present invention provides a route establishment method for centralized meter reading of low-voltage power users. The route establishment method used in the centralized meter reading of low-voltage power users in the first embodiment includes the route learning process of the master node and the route learning process of the slave nodes, wherein, several slave nodes are connected to a master node, and the master node records locally The route link quality information and the reachable node information table of the connected slave nodes, and each slave node records the route exit information table and the reachable node information table respectively locally. see figure 1 As shown in FIG. 1 , it is a schematic diagram of the implementation flow of the route establishment method used in the centralized meter reading of low-voltage power users in Embodiment 1 of the present invention. Such as figure 1 As shown, the route learning process of the master...

Embodiment 2

[0044] According to the route establishment method used in the centralized meter reading of low-voltage power users in the first embodiment above, the second embodiment of the present invention provides a method for centralized meter reading of low-voltage power users. In the second embodiment, the wireless communication module embedded in the concentrator is used as the master node, and the wireless communication module embedded in the communication smart meter or the wireless communication module embedded in the collector is used as the slave node. When a master node is connected, the master node locally records the routing link quality information and the reachable node information table of the connected slave nodes, and each slave node locally records the route exit information table and the reachable node information table respectively. Such as figure 2 shown, see figure 2 As shown in FIG. 2 , it is a schematic flow diagram of the realization of the centralized meter r...

Abstract

The invention relates to a routing establishing method for low-voltage-electric-power-user centralized meter reading and a meter reading method. Routing information and routing change information are both locally recorded in a node. The routing establishing method includes the steps that a primary node records routing-transferring failure causes and judges whether the routing link quality of a secondary node reaches an issue threshold value or not after updating the routing link quality information of the secondary node, and if the routing link quality of the secondary node reaches the issue threshold value, the secondary node is set as an abnormal node; the secondary node updates the link quality value of an outlet node during routing transferring failure, and an alternative node serves as a novel outlet node for replacing when the link quality value of the outlet node is lower than the communication quality value of the alternative node; the primary node and the secondary node also monitor network communication frames of surrounding nodes, and update the link signal indicating values of the surrounding nodes monitoring the network communication frames and reachable node information sheets. By means of the routing establishing method and the meter reading method in the technical scheme, the routing reliability can be improved, the routing overhead can be reduced, and the load balance generated during information transmission is supported; the adaptability to accidental network topology changes is better.
