Turnout switch rail point closure deformation device based on electromagnetism eddy excitement collection

Abstract

The invention belongs to the technical field of railway traffic, and particularly relates to a turnout switch rail point closure deformation device based on electromagnetism eddy excitement collection. The turnout switch rail point closure deformation device based on electromagnetism eddy excitement collection comprises a combined detection coil arranged on a stock rail. The dynamic changes and position states of a turnout switch rail are obtained through the combined detection coil, and multi-group and multi-point real-time data collection is carried out through a high-accuracy excitement collection sensor according to the Faraday law of electromagnetic induction. The turnout switch rail point closure deformation device based on electromagnetism eddy excitement collection further comprises a circuit controller. The circuit controller comprises an excitement circuit module, a transmitting and receiving circuit module, a processing circuit module and a wireless communication circuit module, wherein excitement circuit module is used for providing excitement for the detection coil; the transmitting and receiving circuit module is used for receiving data; the processing circuit module is used for processing signal data; finally, the data are sent to a computer server in a wireless communication mode; data collected by the combined detection coil are transmitted to a circuit control module via a cable. The turnout switch rail point closure deformation device based on electromagnetism eddy excitement collection has the advantages that turnout point closure deformation can be measured in a non-contact mode, accuracy is not affected by temperature changes, and the structure is simple.

Description

technical field [0001] The invention belongs to the technical field of transportation and railways, and in particular relates to a point rail close-fit deformation device based on electromagnetic eddy current excitation collection. Background technique [0002] At present, the detection devices for the basic rail closeness of the switch point rails in my country are mainly the closeness checker produced by Siemens Company of Germany and the JM1 type closeness checker of China Railway Communication and Signal Group Corporation. Both products are installed at the bottom of the basic rail between the first and second traction points or connected to the independent base outside the rail through a long connecting rod, but the principle and internal functions of both are similar to the electrical contact mechanism in the switch machine, and can only The "switch" signal of "pass" and "no pass" is given to whether the close contact between the tip rail and the basic rail is in place...

Both products are installed at the bottom of the basic rail between the first and second traction points or connected to the independent base outside the rail through a long connecting rod, but the principle and internal functions of both are similar to the electrical contact mechanism in the switch machine, and can only The "switch" signal of "pass" and "no pass" is given to whether the close contact between the tip rail and the basic rail is in place, which cannot reflect the continuous change, variation range and frequency of the gap of 0-4mm during close contact, and is more affected by the ambient temperature.
