When some equipments become faulty, how to quickly locate the faulty nodes in a large-scale network has become a major challenge in operation and maintenance. At present, the equipment fault alarm of carrying network depends mainly on the equipment performance logs, which generates many false alarms, and can not adapt to the fault location in a large-scale network. Therefore, by using the tools such as Spark, the abnormal nodes location method based on terminal data is proposed, combining network topology to realize threshold alarm preliminarily. And further based on the analysis of equipment correlation and reliability, a large number of false alarms generated during the process of threshold alarm are cleaned to improve the precision rate of fault location. The experimental results show that this method has high practical value and its precision rate can reach 89% in the fault location of carrying network. %U http://cea.ceaj.org/EN/10.3778/j.issn.1002-8331.1804-0061
