Embodiment 1

[0036] A dual-network routing method, comprising the steps of: initializing a node, registering a communication node, and generating a routing table; using the first communication link to send data, and switching to the second communication link preferentially if the communication link is interrupted, Continue to send data, switching time is less than 100ms

[0037] The routing table includes at least one of a first communication link routing table and a second communication link routing table. The routing table contains the routing information between the user node and the central node (concentrator communication node in the AMR / AMI system).

[0038] Here, preferentially switching to the second communication link means that if the first communication link is interrupted, the current node first detects whether it has generated a routing table for the second communication link, and if so, sends a switching routing message switching To the second communication link, the node th...

[0047] A dual-network routing method, comprising the steps of: initializing a node, registering a communication node, and generating a routing table; using the first communication link to send data, and switching to the second communication link preferentially if the communication link is interrupted, Continue to send data.

[0048] Wherein, the type of generating the routing table includes at least one of the first communication link routing table and the second communication link routing table. routing information between nodes).

[0049] Here, preferentially switching to the second communication link refers to: if the first communication link is interrupted, the current node first detects whether it has generated a second communication link routing table, and if so, first sends a switch routing message , switch the data transmission to the second communication link, and the node receiving the switch routing message activates the corresponding communication link routing tab...

Embodiment 3

[0061] The dual-network routing network involved in the present invention includes a plurality of communication nodes, each of which supports at least one of wireless communication links and power line communication links. Correspondingly, the communication node includes at least one of a wireless communication module and a power line communication module.

[0062] Dual-network routing communication supports various network topologies such as star, tree, and mesh. The network can also be composed of several to hundreds of communication nodes. Each communication node can only support wireless communication or power line communication, or it can Both power line communication and wireless communication are supported. In terms of hardware, the communication node is composed of CPU, FLASH, EEROM, power supply, switching chip, various communication modules and other accessories.

[0063] The communication module can be selected according to the actual situation. If the actual busin...

Abstract

The invention relates to a dual-network routing method. The method comprises the following steps: nodes are initialized to establish routing registry connection and generate a routing list; a first communication link is adopted for transmitting data, and the first communication link is preferentially switched to a second communication link to continue to transmit data in the case of communication link interrupt. The first communication link is a wireless communication link, the second communication link is a power line communication link, and vice versa. The method has the advantages that higher communication reliability and carrier class reliability are realized, communication real-time property is guaranteed, and the technical problem of signal island in the prior art is solved.

Description

technical field [0001] The invention relates to a dual-network routing method. Background technique [0002] In the power industry, AMR (Automatic Meter Reading System) has been developed for more than 20 years. As long as it is used to realize remote meter reading for electricity users, generally, meter reading and billing are performed once a month. [0003] AMI (Advanced Metering System) is the basis for the development of smart grid and the first step in the development of smart grid. It includes all the functions of the AMR system, such as remote meter reading, and on this basis, it can reduce the energy consumption of life and production, and save energy. emission reduction. In addition, it also includes more new content, such as real-time collection of electricity consumption information of various users on demand, implementation of real-time electricity prices, support for distributed power sources, power outage detection, support for smart homes, remote control of ...
