Embodiment Construction

[0020] Such as figure 1 The shown provides a method for real-time monitoring of catenary components: the strain sensor group senses the force and transmits the signal to the signal processing transmitter, and the signal processed by the signal processing transmitter is transmitted to the communication Gateway, the signal received by the communication gateway is transmitted to the user for real-time monitoring. Specifically, the real-time detection method for the catenary cable seat and the anchor support positioning clip is as follows: a pair of strain sensor groups are respectively installed on the catenary cable seat and the anchor support positioning clip, and the strain sensor senses the position of the catenary cable seat and the anchor support position. The stress change on the clamp transmits the signal to the respective signal processing transmitters, and the signals transmitted from the strain sensor are processed by the signal processing transmitters, and then the si...

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...
