A networking method of a power line carrier module applied to electricity information collection

Abstract

The invention discloses a networking method for a power line carrier module applied to power utilization information acquisition. A master node-dominated networking way is adopted in a networking initialization process; a beacon message is sent by a master node; network access applications are initiated specific to slave nodes which receive the beacon message sent by the master node; and silent modes are kept and channel access is not performed specific to slave nodes which do not receive the beacon message sent by the master node. The networking method for the power line carrier module applied to power utilization information acquisition is provided through redesign of a networking flow, the master node-dominated networking way is adopted, and a time slot allocation mechanism is introduced to allocate a dedicated contention slot and a dedicated non-contention slot to networking, so that the channel access times of the nodes are reduced; an entire networking process is more ordered; and the networking time can be shortened greatly and effectively.

Description

technical field [0001] The invention relates to a networking technology, in particular to a networking method of a power line carrier module applied to electricity information collection, and belongs to the technical field of power line carrier communication. Background technique [0002] Power line carrier communication is a technology that uses existing power transmission lines for information transmission. It does not require wiring and is a low-cost and effective data communication method. [0003] At present, power line carrier communication technology has applications in the fields of power consumption information collection, smart home, smart street lamps, etc., especially in the field of power consumption information collection, more than 80% of electric energy meters use power line carrier to upload power consumption information . [0004] In the field of electricity information collection, the concentrator needs to collect information from the energy meters within...

Problems solved by technology

Each slave node needs to occupy the channel multiple times and needs to compete multiple times, which increases the workload of the slave node

[0018] 3. Lack of active network maintenance mechanism

[0019] The above-mentioned disadvantages 1 and 2 both result in too long network networking time. Usually, a master node manages 100 slave nodes, which takes about 24 hours of networking time, which seriously affects the engineering efficiency; while disadvantage 3 does not have The periodic characteristics of the power line are used to re-evaluate the path, so that the communication does not make full use of the optimal route, which seriously affects the rate of power information collection.
