Distributed data transmission method for power line monitoring system on basis of wireless sensor network

Abstract

The invention relates to a distributed data transmission method for a power line monitoring system on the basis of a wireless sensor network, which comprises the following steps: 1, a sensor node uses T as a work cycle and on an initiation phase of each cycle and carries out time synchronization with a sink by capturing a beacon; 2, the sensor node exchanges node information with a neighbor by broadcasting so as to determine a node which needs to be subjected to data transmission in the cycle; 3, by sending the communication accessibility and local network energy load balancing between the nodes, a relay node is selected as a relay for data transmission in a distributed mode; 4, the relay node selection phase is initiated and a sensor node without data transmission in the cycle is selected as the relay node; 5, a node which needs to be awakened at the data transmission node is processed in a distributed mode; and 6, a step-shaped data uploading link is adopted to carry out awakening / sleeping scheduling on the node. The distributed data transmission method is applicable to a chain multi-hop network and energy load balancing of the power line monitoring system on the basis of the wireless sensor network.

Description

technical field [0001] The invention relates to a data transmission method of a power line monitoring system, in particular to a distributed data transmission method of a power line monitoring system based on a wireless sensor network. Background technique [0002] The power line transmission system is an important part of the power system, and its stable operation directly affects the country's economic development and people's lives. At the same time, there are many distribution points and wide areas of power line transmission lines. Most of them are far away from cities and towns. The terrain is complex and the natural environment is harsh. It is easy to cause power lines to break due to natural disasters or fatigue accumulation, resulting in serious power outages. Therefore, it is necessary to establish a power line monitoring system to monitor the environmental factors and tension of the power line in real time, and to be able to warn of dangerous situations in time.
