研究超高频RFID施工升降机的电源故障检测问题。施工现场的电源大多是通过母线并入现场配电网络，而升降机的分布式电源直接并入配电网，线路中间增加多余的支路，对线路两侧的电流大小、方向造成影响，容易造成故障信号的波动。传统的故障检测方法很难对这种随机波动进行准确分类，导致检测的准确性较低。为此，提出基于故障特征相关性残差补偿的超高频RFID施工升降机电源故障检测算法。首先，计算故障信号特征之间的相似性，从而对故障信号中的误差进行补偿；然后根据故障特征相似性，计算故障空间位置，从而实现超高频RFID施工升降机电源故障检测。实验结果表明，利用改进的算法能够有效提高电源故障检测的准确性。

Research uhf RFID construction elevator power failure accurate detection problem. This paper put for-ward a fault feature based on correlation residual compensation algorithm of uhf RFID construction elevator power fault detection method. The relationship between the fault signal characteristics was calculated, and the fault signal of the error was compensated. According to the fault characteristic similarity, weccalculated the fault space position, so as to realize the uhf RFID construction elevator power fault detection. The experimental results show that the algorithm can effectively improve the accuracy of the power supply fault detection.
