Low-power-consumption railway seamless track crawling monitoring device and method

Abstract

The invention provides a low-power-consumption railway seamless track crawling monitoring device and method. The low-power-consumption railway seamless track crawling monitoring device comprises a sensor unit, a processor unit and a remote communication unit. The sensor unit comprises a temperature sensor and an inertia sensor which are attached to a steel rail, and a capacitive grating displacement sensor used for measuring the creeping distance, the capacitive grating displacement sensor comprises a fixed grating ruler and a movable grating ruler, and the fixed grating ruler is in rigid connection with the steel rail; the sensor unit and the remote communication unit are electrically connected with the processor unit. Steel rail temperature data, xyz-direction acceleration data and moving grating ruler displacement data, namely railway creeping distance, are collected, analyzed, transmitted and processed through the electronic sensor, and different from a traditional high-power-consumption electronic sensor and a monitoring system, remote monitoring and vibration awakening functions are achieved, so that the overall service life of the device is greatly prolonged. The evaluation rate of power supply replacement is reduced, and high-precision, remote, automatic, intelligent, low-power-consumption and low-cost monitoring of seamless steel rail monitoring is realized.

Description

technical field [0001] The invention relates to the field of railway maintenance, in particular to a low-power-consumption railway seamless track crawling monitoring device and method. Background technique [0002] In recent years, my country's railway construction has developed rapidly. In order to improve driving speed, train load and safety performance, seamless rail technology is widely used in my country's lines. In the past, the length of a single rail was small and there were many expansion joints, so it was less affected by expansion; the seamless rail was welded to a length of 25 meters and connected to a length of hundreds of meters or even thousands of meters, but the seamless rail Unable to expand and contract freely, relying on the fixing of fasteners to eliminate the influence of temperature changes, vibrations, etc. The length of a seamless steel rail can reach tens of kilometers. When the temperature changes or the train runs for a long time, the rail will b...

Problems solved by technology

When measuring, it is necessary to place the main engine on the displacement observation pile, and mark the points to be measured on the rail. The displacement data is measured by the main engine using optical imaging technology, but whether it is the Chinese patent with the authorized publication number CN204432678U or the photoelectric measurement technology , the problem of high power consumption is still unsolved, and it is urgent to improve
