工業(yè)焊接機器人機械，電氣系統(tǒng)復(fù)雜，工作區(qū)域大，運行速度快，因而無法準確預(yù)測在不同工況下有可能出現(xiàn)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(tǒng)缺陷都有可能造成設(shè)備損壞甚引發(fā)重大事故。那么如何在焊接機器人進行設(shè)備預(yù)測性維護？山東數(shù)控焊接設(shè)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(yù)測性維護的分類

Classification of Predictive Maintenance

預(yù)測性維護可以分為基于設(shè)備機理和基于數(shù)據(jù)驅(qū)動預(yù)測兩種類型?；跈C理模型的預(yù)測是建立設(shè)備故障與機械動力學(xué)、熱力學(xué)和計量學(xué)等數(shù)學(xué)模型的關(guān)聯(lián)關(guān)系預(yù)測設(shè)備故障，而數(shù)據(jù)驅(qū)動模型則是通過大量數(shù)據(jù)的學(xué)習(xí)和訓(xùn)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(zhuǎn)類設(shè)備，數(shù)據(jù)驅(qū)動模型更適用于復(fù)雜不確定系統(tǒng)和黑箱過程的預(yù)測和控制，數(shù)據(jù)驅(qū)動模型是基于經(jīng)驗數(shù)據(jù)統(tǒng)計關(guān)系或統(tǒng)計特征的預(yù)測和控制方法，其效果依賴于輸入數(shù)據(jù)的準確性和響應(yīng)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.
