工業焊接機器人機械，電氣系統復雜，工作區域大，運行速度快，因而無法準確預測在不同工況下有可能出現的所有危險，尤其在人工示教編程或者維護時，任何操作失誤和未知的系統缺陷都有可能造成設備損壞甚引發重大事故。那么如何在焊接機器人進行設備預測性維護？山東數控焊接設備廠家為您分析：

The mechanical and electrical systems of industrial welding robots are complex, with large working areas and fast operating speeds, making it difficult to accurately predict all the hazards that may occur under different working conditions. Especially during manual teaching programming or maintenance, any operational errors and unknown system defects may cause equipment damage or even major safety accidents. So how to perform predictive maintenance on welding robots? Shandong CNC welding equipment manufacturer analyzes for you:

預測性維護的分類

Classification of Predictive Maintenance

預測性維護可以分為基于設備機理和基于數據驅動預測兩種類型。基于機理模型的預測是建立設備故障與機械動力學、熱力學和計量學等數學模型的關聯關系預測設備故障，而數據驅動模型則是通過大量數據的學習和訓練，形成智能化的決策模型。

Predictive maintenance can be divided into two types: device mechanism based and data-driven prediction based. The prediction based on mechanism model is to establish the relationship between equipment failure and mathematical models such as mechanical dynamics, thermodynamics and metrology to predict equipment failure, while the data-driven model is to form an intelligent decision-making model through learning and training a large amount of data.

前者更適用于旋轉類設備，數據驅動模型更適用于復雜不確定系統和黑箱過程的預測和控制，數據驅動模型是基于經驗數據統計關系或統計特征的預測和控制方法，其效果依賴于輸入數據的準確性和響應頻率。

The former is more suitable for rotating equipment, while data-driven models are more suitable for prediction and control of complex uncertain systems and black box processes. Data-driven models are prediction and control methods based on empirical data statistical relationships or statistical features, and their effectiveness depends on the accuracy and response frequency of input data.
