Device for wirelessly monitoring turnout resistance

Abstract

The invention discloses a device for wirelessly monitoring turnout resistance, which comprises a wireless structural member detachably mounted on an actuating rod of a switch machine. A solar cell panel is arranged on the wireless structural member, and a sensor, a wireless communication module and an energy collection management module are all connected with a main control processing unit and embedded in the wireless structural member. The device is simple in structure, small and light in size and simple in installation structure, and the turnout switch machine actuating rods are reliably fixed together through the fixing bolts in a mode that the structural member A and the structural member B form a split structure and surround the structural member A and the structural member B. Assembly and disassembly are convenient and quick. When the turnout switch machine is maintained and an actuating rod is replaced, the operation efficiency is improved, and the precious skylight time is saved. No cable or cable connection exists outside, the structure of the turnout switch machine is not changed, normal work of the turnout switch machine is not affected even if the device breaks down, and potential safety hazards of driving caused by the external cable are avoided.

Description

technical field [0001] The invention relates to the technical field of railway switch resistance monitoring, in particular to a device for wirelessly monitoring switch resistance. Background technique [0002] In the huge railway network, the turnout switch machine, as an important part of the turnout system, is the basic power link to complete the precise branch control of trains traveling from south to north. When the turnout sliding bed plate cannot be lubricated due to lack of oil, or the turnout is jammed, etc., the resistance of the turnout conversion will increase, which may affect the close fit or cause the switch to fail to switch normally, resulting in a switch conversion failure and affecting driving safety. [0003] At present, the common solution to monitor the resistance of the switch machine is to install the load cell on the action rod, but in this kind of solution, the cable is connected to the load cell or its components, and the cable is easy to be damaged...

AI Technical Summary

Problems solved by technology

When the sliding bed plate of the turnout cannot be lubricated due to lack of oil, or the turnout is jammed, etc., the resistance of the turnout conversion will become larger, which may affect the close fit or cause the switch to fail to switch normally, resulting in a switch conversion failure and affecting driving safety.

[0003] At present, the common solution to monitor the resistance of the switch machine is to install the load cell on the action rod, but in this kind of solution, the cable is connected to the load cell or its components, and the cable is easy to be damaged and damaged on site. Various problems such as line extrusion, and the installation is more cumbersome and complicated, prone to various problems
