The invention relates to an RFID-based intelligent auxiliary equipment positioning method for substation project acceptance. The RFID-based intelligent auxiliary equipment positioning method comprisesthe following steps: defining the substation equipment by RFID electronic tags; then intelligently recognizing the equipment information of the substation equipment by a handheld intelligent terminalcombined with image recognition and processing algorithms; and finally, based on three-dimensional digital model and BIM model information of the equipment transferred in a substation project designprocess, verifying the placing position of the substation equipment, and comparing whether the equipment information is accurate, thereby realizing three-dimensional digital acceptance of a substationproject. The RFID-based intelligent auxiliary equipment positioning method solves the problem that an acceptance link of the existing substation projects adopts manual inspection which is time-consuming, laborious and low in efficiency, saves a lot of manpower, improves the reliability of the result detection, and effectively solves the problem that GPS satellite positioning cannot be used when an indoor project is accepted or the problem of inaccurate positioning.
