Abstract: The three-dimensional library of power equipment bears the heavy responsibility of storing, distributing and maintaining all kinds of power equipment, and its management efficiency and accuracy are directly related to the stable operation and power supply reliability of power system. The design and installation position of RFID tags are difficult to ensure the reading rate and stability of tags, which leads to poor effect and low efficiency of intelligent disk library. Therefore, this paper puts forward an intelligent disk library method for power equipment three-dimensional library under RFID. Automatically identify the radio frequency tag information of power equipment on the cargo platform, design a radio frequency identification card reader for power equipment information identification, and establish a power equipment fork path planning model. When using improved genetic algorithm to solve the intelligent disk library of power equipment three-dimensional library, the power equipment fork path planning model is used to get the shortest power equipment fork path. Under the radio frequency identification, the method flow of intelligent disk library of power equipment three-dimensional library is designed. Experiments show that this method can effectively and automatically identify the radio frequency tag information of power equipment, effectively plan the intelligent disk library path of the three-dimensional library of power equipment, and the disk library has high accuracy and high efficiency.
