Wind driven generator paddle health monitoring method and monitoring system thereof

Abstract

The invention discloses a wind driven generator paddle health monitoring method and a monitoring system thereof. Light sensor modules are arranged in a paddle every other 0.3-0.8 m; the light sensor modules obtain ambient light intensity and convert the ambient light intensity into digital signals, and the digital signals are transmitted to a paddle main control system after being filtered and aggregated; the paddle main control system polls the digital signals of the sensor modules and then wirelessly transmits the digital signals to an edge gateway, the edge gateway receives all the digital signals to perform artificial intelligence mode recognition and transmits a recognition result to a cloud platform, the cloud platform outputs a control command according to the recognition result, the control command is transmitted to the paddle main control system through the edge gateway, and the paddle main control system executes the control command. The wind driven generator paddle health monitoring system can perform health monitoring on the wind driven generator paddle, and has the advantages of wide monitoring range, and reliable communication connection and data transmission processing.

Description

technical field [0001] The invention relates to the technical field of blade monitoring, in particular to a method for monitoring the health of blades of a wind power generator and a monitoring system thereof. Background technique [0002] The coordinated development of economy, energy and environment is a necessary condition for realizing the goal of national modernization. With the global warming and the continuous consumption of fossil energy and its impact on the environment, the development of other energy sources has been paid more and more attention. Among these emerging energy types, wind energy, as one of the conversion forms of solar energy, is an inexhaustible clean and renewable energy source that does not produce any harmful gases and fertilizers, does not pollute the environment, and has great potential for development. Huge and promising. The power generation method adopted by the current wind power generator is that the wind drives the turbine to rotate, an...

AI Technical Summary

Problems solved by technology

This processing method has the following problems: 1. Each sensor must be connected to the acquisition unit, which cannot be cascaded. As a result, this solution can only be concentrated on the root, and the monitoring range is limited. According to the actual operation situation, the root of the blade is cracked. The situation rarely happens; 2. The sensor has no processing power, and the data is collected centrally by the back-end. The amount of data generated by the collection is large, and the complex analysis is carried out in the center or on the cloud.

3. Weak or impossible to expand

4. Powered by battery, low reliability and high maintenance cost
