摘　　要：针对现有预警方法无法实现防碰撞要求的问题,引入光纤传感,开展采煤机截割滚筒防碰撞自动预警方法设计研究。该方法首先利用光纤传感采集信号,并将光信号转变为电信号,然后结合振动能量、频率分布等预警指标,构建采煤机截割滚筒防碰撞预警模型,最后设计采煤机截割滚筒防碰撞逻辑,通过ARIMA模型的构建,实现自适应自动预警。实验证明,应用设计预警方法可有效避免采煤机截割滚筒碰撞,提高采煤机运行使用的安全性。In response to the problem that existing warning methods cannot meet collision prevention requirements,fiber optic sensing is introduced to carry out research on the design of automatic collision prevention warning methods for coal mining machine cutting drums.This method first uses fiber optic sensing to collect signals,converts the optical signals into electrical signals,and then combines warning indicators such as vibration energy and frequency distribution to construct an anti-collision warning model for the cutting drum of the coal mining machine.Finally,the anti-collision logic of the cutting drum of the coal mining machine is designed,and an adaptive automatic warning is achieved through the construction of an ARIMA model.Experimental results have shown that the application of design warning methods can effectively avoid collisions between the cutting drum of coal mining machines and improve the safety of their operation and use.
