The invention discloses a label-based electric power acquisition operation and maintenance object portrait method, and belongs to the technical field of electric power. According to an existing electric power operation and maintenance system, operation and production personnel cannot grasp related information of an operation and maintenance object in advance and can know specific conditions only after arriving at an operation and maintenance site, and the operation efficiency is low. According to the invention, label portrait description is carried out on the electric power acquisition operation and maintenance object by adopting a label portrait technology; a label portrait system, label generation and label full life cycle management means are designed; according to the power consumptiondata acquisition and operation and maintenance system and method based on the big data technology, label portraying is conducted on power acquisition and operation and maintenance objects, the characteristics of the acquisition and operation and maintenance objects are visually displayed, and in the work order processing link, operation and maintenance personnel can grasp information in advance,take measures and improve operation and maintenance efficiency by checking the label portraying, and then guarantee is provided for power consumption data acquisition.
