Abstract： An application research of the operation and maintenance mobile assignment using the machine learning RFID hybrid model is proposed to overcome the shortcomings of the traditional operation and maintenance method that can not accurately locate the fault point. The RFID technology and the decision tree algorithm are combined to establish a machine learning RFID hybrid model. On the basis of the model， the tag corresponding to the operation and maintenance inspection point is identified with the RFID technology and the RFID reader in the mobile operation device to complete the data acquisition of the operation and maintenance inspection point. The deduplication filtering algorithm is used to remove the collected duplicate data. The supervised learning and the training data are used to accurately classify the fault point and the non?fault point， and then the operation and maintenance processing is adopted for the classification result to achieve the design of the operation and maintenance mobile assignment method using the machine learning RFID hybrid model. A contrast experiment of the method designed in this paper and the traditional operation and maintenance method was carried out. The experimental results show that the designed operation and maintenance mobile operation method using machine learning RFID hybrid model have higher positioning accuracy.

近年來，隨著運維檢修工作量的不斷加大，傳統的運維檢修方法已無法滿足實際需求，需要開發新的技術和方法提高運維檢修技術的水平。目前，一些企業采用移動作業的方式，改進了運維檢修的模式，為運維檢修工作提供了便利[1]。然而，現有的運維檢修移動作業方法無法及時、準確地識別出需要做運維檢修處理的目標位置，導致運維檢修的效率大大下降[2?4]。隨著科技水平的不斷提高，機器學習和射頻識別技術得到了不斷的發展?！?br>
