The invention discloses a method for monitoring and judging the state of an overhead line through vibration frequency, and the method comprises the following steps: 1, collecting original acceleration data of each dimension through an acceleration sensor, and extracting frequency spectrum characteristics and acceleration vector data through an algorithm chip; step 2, uploading the data to a collection transponder through a wireless transmission chip; step 3, uploading the data to a server and storing the data in a database, and judging whether the overhead line at the installation position fails or not by a server end program in combination with historical monitoring data of each overhead line monitor; 4, presenting the information to a user through a user side program; and step 5, the server-side program performs self-correction calculation through machine learning according to user feedback. The invention relates to the technical field of overhead line monitoring. According to the invention, the method is n
