Abstract

The invention discloses a surface acoustic wave technology-based train axle state monitoring device. The device comprises a mainframe monitoring system, signal readers-writers and surface acoustic sensing networks, wherein the mainframe monitoring system is arranged in a train headstock control room; the signal readers-writers are arranged at the bottoms of carriages; the surface acoustic sensing networks are mounted on the axles at the bottoms of the carriages; the surface acoustic sensing networks are connected with the signal readers-writers through radio frequency identification; and the signal readers-writers are connected with the mainframe monitoring system through a wireless network. According to the surface acoustic wave technology-based train axle state monitoring device disclosed by the invention, omnibearing real-time monitoring can be carried out on the train axle states, the faults can be warned in advance, the fault positions can be correctly positioned, and cables or optical cables do not need to be paved in the carriages for communication.

Description

technical field [0001] The invention belongs to the technical field of axle state monitoring, and in particular relates to a train axle state monitoring device based on surface acoustic wave technology. Background technique [0002] With the rapid development of my country's railway construction industry, the train speed and carrying capacity are increasing day by day, and railway transportation has gradually become the backbone of the comprehensive transportation system. As a particularly critical component in the process of train travel, the train axle is usually in a high-speed and heavy-load working state. The contact parts between the axle and the wheels, gearboxes and axle boxes are subjected to various mechanical friction and alternating contact stresses for a long time. , there will also be phenomena such as foreign matter falling in, poor lubrication, etc., which will lead to aggravated axle wear and fatigue cracks for a long time, causing problems such as increased...
