Description

technical field [0001] The invention belongs to the field of catenary technology, in particular to an active and wireless-based real-time on-line monitoring device for the state of key components at anchor joints of the catenary. Background technique [0002] In the catenary, at present, most of the stress conditions of components are measured and analyzed by simulating specific working conditions in discrete arbitrary time. effective monitoring. The stress of the key components of catenary is related to the tension of anchor section, pull-out value, elevation, and curve radius, and shows great differences at different nodes. Therefore, a real-time on-line monitoring device that can monitor the force of key parts of the catenary on the line is designed to monitor the key parts of the anchor joint position with more complex force conditions in the line, so that the operation and maintenance unit can grasp the status of the catenary. Working status, early warning of hidden d...
