Problems solved by technology

However, due to the special position of the positioner, direct use of the monitoring ball will seriously affect the operation of the positioner itself, so a suitable solution is needed to complete the operation status monitoring of the positioner without affecting the normal operation of the positioner

Abstract

The invention relates to a device and a method for monitoring the running state of a contact network positioner, and the method comprises the steps: fixing an inertial sensor at the far end of the positioner, enabling the inertial sensor to vibrate along with the vibration of a contact line, and enabling the inertial sensor to transmit measured data to a transceiver through a cable in a remote wired communication method; the transceiver is fixed at an inclined pull arm of the overhead line system and is used for primarily processing the data of the inertial sensor and sending an analyzed result to the signal transmission center; the vibration condition of the far end of the positioner can be monitored through the sensor fixed to the far end of the positioner, the split type design is adopted, and normal work of the positioner is not affected; the device is connected with the positioner through the data cable passing through the inner cavity of the positioner, and the connection is firm; the device can continuously work in a field environment without power supply, and has good environmental adaptability.

Description

technical field [0001] The invention relates to the technical field of sensor monitoring, in particular to a device and method for monitoring the operating state of a catenary positioner. Background technique [0002] The electrified railway catenary is arranged in the open air along the railway line, and it is eroded by wind, frost, rain, snow and other natural environments all the year round, and its mechanical and electrical performance states are dynamically changing. As an important part of the high-speed railway power supply system, the catenary system needs to be effectively monitored for its infrastructure. [0003] At present, there are running status monitoring schemes for additional wires, hanging strings and other components. Compared with these components, the positioner is directly connected to the contact line, responsible for the limit and protection of the contact line, and has a particularly important position in the catenary system. There is an urgent nee...
