Embodiment Construction

[0019] In order to make the content of the present invention clearer and easier to understand, the content of the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0020] The invention provides an online monitoring method for fan blades based on the Zigbee protocol. The lightning strike monitoring of fan blades is mainly to realize the alarm of lightning strikes on the blades by arranging wireless sensor nodes inside the blades of the fan to detect the temperature and brightness inside the blades. The main content of the patent of the present invention is the targeted design of the acquisition strategy, communication structure and signal anti-interference measures of wireless monitoring.

[0021] 1) Acquisition strategy: The present invention mainly monitors the blades of the fan. A fan has at most three blades, and the parts of the blades of the fan that are most likely to be struck by lightning are conce...

Abstract

This invention puts forward a fan blade lightning stroke monitoring method based on a ZigBee protocol. A system comprises a plurality of routing function nodes, a coordinator and a cabin control cabinet, wherein the routing function nodes are arranged in fan blades and used for collecting the temperature and the light brightness in the fan blades in a starting state; the routing function nodes are in mutual communication based on the ZigBee protocol and are in communication with the coordinator based on the ZigBee protocol, and therefore any routing function node can directly transmit collected data representing the temperature and the light brightness in the fan blades to the coordinator or transmit the collected data to the coordinator through other routing function nodes; besides, when the coordinator receives the collected data from the routing function nodes, the collected data are transmitted to the cabin control device.

Description

technical field [0001] The invention relates to the field of on-line monitoring of lightning strike damage to wind turbine blades, and more specifically, the invention relates to a lightning strike monitoring method for wind turbine blades based on the ZigBee protocol. Background technique [0002] In recent years, large-scale wind power generation technology has become more and more mature, and high-power wind power generators have gradually occupied the wind power market. At present, the most active wind turbines have a single unit capacity of 1.5MW to 2.5MW, their hub height has reached 60 to 100 meters, and the blade length has reached 35 to 50 meters, because wind farms are generally located in open remote areas or by the sea, and the surrounding buildings are relatively low, so wind turbines become the main target of lightning strikes. [0003] Today's wind turbine blade lightning protection is designed according to IEC62305-1 level I protection level. Lightning recept...
