Dual-mode heterogeneous network networking communication method for power information collection system

Abstract

The invention relates to a dual-mode heterogeneous network networking communication method for a power information collection system, and belongs to the technical field of power consumption information collection. The method comprises the following steps: S1: constructing a dual-tree network for micro-power wireless and power carriers in combination with the distribution characteristic of power collection equipment and the difference between micro-power wireless and power carrier signal attenuation; S2: evaluating, by an equipment node, the communication performance of the power carriers and the a micro-power wireless channel, and performing postorder traversal on a routing forwarding tree to discover channel selection and routing addressing; and S3: collecting, by a concentrator node, power data according to the constructed dual-tree network. According to the method of the invention, the concentrator is ensured to collect the power data at a relatively higher success rate through a file updating mechanism and a retransmission mechanism. By adoption of the dual-mode heterogeneous network networking communication method provided by the invention, a dual-mode heterogeneous meter reading network can be reasonably constructed, the collection success rate of the power data is greatly improved, and a certain reference is further provided for cross-network transmission of the power data.

Description

technical field [0001] The invention belongs to the technical field of electric information collection, and relates to a dual-mode heterogeneous network networking communication method for electric power information collection systems. Background technique [0002] With the transformation and upgrading of the power grid, cross-network transmission of power data and multi-mode communication have become the current development trend of power information collection. The current mainstream power acquisition communication technologies include: power line carrier network communication technology, micro-power wireless network communication technology, 485 bus technology, etc. Among them, power line carrier and micro-power wireless are the two most widely used communication technologies. However, in the power information collection system, the success rate of power data collection is difficult to break through simply using power line carrier or micro-power wireless technology for ne...
