AI Technical Summary

Technical Problem

In the existing technology, the row detection accuracy of the residual film recovery machine is limited, especially in field operations, where dust and irregular layout of cotton stalks have a serious impact, resulting in low efficiency of mechanized residual film recovery.

Method used

By combining a mechanical touch structure with an FBG pressure sensor, real-time high-precision measurement is achieved through the contact between the paddle and the cotton stalk. The FBG pressure sensor is used to obtain pressure signals in real time, and the tractor's electronic steering wheel is controlled to adjust the driving direction, ensuring the accuracy of row detection.

Benefits of technology

The row-alignment measurement accuracy and stability of the residual film recovery machine are improved, the residual film recovery efficiency is improved, and it is suitable for auxiliary row-alignment functions in field operations.
