The invention discloses a construction method and device of an equipment model, and belongs to the technical field of oil and gas pipelines. The method includes: acquiring multiple pieces of attributeinformation of target equipment and a technology code of each attribute information; identifying the technology code of each attribute information to obtain information of a level to which each technology code belongs, wherein the level information is used to describe the layer level where the attribute information of the equipment is located in a preset model structure; and setting the multiplepieces of attribute information onto corresponding positions in the preset model structure on the basis of the information of the level, to which each technology code belongs, to obtain the equipmentmodel of the target equipment. According to the method, the technology codes of the multiple pieces of acquired attribute information of the target equipment are identified, thus the multiple pieces of attribute information may be set onto the corresponding positions in the preset model structure for obtaining the equipment model of the target equipment, and thus workloads of a user are reduced, and efficiency and a success rate of equipment model construction are improved.
