AI Technical Summary

Technical Problem

Existing starting wind speed measuring instruments are not sensitive enough, have limited detection range and high false negative rate under complex surface conditions such as farmland, stubble land and irrigated grassland, making it difficult to accurately capture soil starting wind speed.

Method used

It employs a fixed support device, wind speed sensor, fiber optic sensor assembly, and data acquisition and recording module, including a base, column, horizontal arm sensor fixture, wind direction sensor, and fiber optic probe. Combined with a signal amplifier and a multi-channel data acquisition unit, it forms a rectangular detection cross section to ensure signal stability and data synchronization.

Benefits of technology

It significantly improves the detection range and sensitivity, reduces the false negative rate, ensures the stability and accuracy of monitoring results, and is suitable for a variety of complex surface environments.
