Embodiment

[0058] In this embodiment, a wind farm wireless monitoring network is built according to the cluster tree network structure, and a wireless network coordinator is used as the root node of the cluster tree routing network. The wind turbine at the end of the route is equipped with a simplified wireless routing terminal. Each full-functional wireless router and simplified wireless routing terminal are respectively used as a routing node in the cluster tree routing network, and are allocated corresponding The node address, the location of each node and the allocation of routing addresses are as follows: figure 2 shown; in the cluster tree network, each full-featured wireless router also stores a preset power consumption threshold E th and their corresponding neighbor node tables. The neighbor node table stored in each full-function wireless router is used to record the node addresses of the neighbor nodes adjacent to its own peripheral position. For example, the terminal node wh...

Abstract

The invention provides a data routing transmission control method of a wireless autonomous monitoring network of a wind farm. By adopting the data routing transmission control method of a wireless autonomous monitoring network of a wind farm provided by the invention, when a node performing data transmission and a destination node are positioned in different sub-tree clusters, as long as a neighbor node meeting the routing conditions and the energy storage requirements exists, cross-tree cluster routing transmission is directly performed without the necessity of forwarding through a root node (a network coordinator) again, thus the routing path is effectively shortened, the routing transmission delay is reduced, and the real-time property of data transmission of the wireless autonomous monitoring network of the wind farm is improved; and moreover, the method also performs judgment on the energy storage conditions of the neighbor node, the phenomenon that ongoing data routing transmission cannot be supported due to insufficient energy storage of the neighbor node during the cross-tree cluster routing transmission is avoided, and the data transmission safety of the wireless autonomous monitoring network of the wind farm is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment and the technical field of communication, in particular to a data routing transmission control method for a wireless autonomous monitoring network of a wind farm. Background technique [0002] With the rapid increase in the capacity of large-scale wind turbines (also referred to as wind turbines), wind turbines are now developing from hundreds of kilowatts to mega-levels, and the mechanical structure is becoming increasingly complex, and the interconnection and coupling between different components have become increasingly complex. Even more closely, the failure of one component could disrupt the entire power generation process. In addition, with the rapid development of wind turbines in recent years, the maturity of its technology cannot keep up with the development speed of wind turbines. There have been a large number of reports in the media about the damage of wind turb...
