AI Technical Summary

Technical Problem

Existing early warning methods for agricultural drive shafts rely on fixed torque thresholds, which can lead to false alarms or missed alarms. They cannot effectively detect weed entanglement, causing the drive shaft to suddenly seize up and become damaged.

Method used

By collecting real-time torque and speed signals of the drive shaft, the weed entanglement coefficient is calculated, and the hydraulic solenoid valve is used to control the clutch to cut off the power output, thus preventing the drive shaft from suddenly locking up.

Benefits of technology

It enables accurate detection of slow weed entanglement, avoids damage to the drive shaft and gearbox, and improves the safety and reliability of the equipment.

Abstract

本发明公开了一种农用传动轴力矩实时监测及设备安全控制系统及方法，涉及农用传动轴技术领域，实时采集传动轴的力矩与输出端转速信号，经清洗同步后计算杂草缠绕系数；若判定为杂草缠绕，则通过液压电磁阀切换油路，使离合器分离，迅速切断动力输出，避免传动轴损坏。本发明通过力矩与转速双维度融合判断，避免正常工况误报；采用相邻时段比值累加，捕捉力矩缓升过程，解决漏报问题；配合动态阈值，超限后迅速切断动力输出，防止传动轴冲击损坏。
