Freight train axle state monitoring and early warning system and method

Abstract

The invention discloses a freight train axle state monitoring and early warning system and method. The system comprises a transmission processing unit arranged at the head of a train, a data acquisition unit arranged in each carriage, and a ground monitoring unit, and the transmission processing unit is respectively connected with the data acquisition unit and the ground monitoring unit. The dataacquisition unit of each carriage is used for acquiring state data of an axle through a plurality of sensors; the Zig-Bee ad hoc network is adopted to transmit the data acquired by the sensor to the transmission processing unit for convergence; and the state data of the axle is sent to the ground monitoring unit, so that the state data of the axle is analyzed and processed, multi-stage pre-warninginformation and a corresponding fault diagnosis and maintenance proposal are formed and sent to the transmission processing unit, and thus a worker is helped to quickly locate a fault.

Description

technical field [0001] The invention relates to a freight train axle state monitoring and early warning system, and also relates to a freight train axle state monitoring and early warning method, which belongs to the technical field of vehicle monitoring. Background technique [0002] The axle of a railway freight train is a key part of the running part of the train, and it is also one of the most easily damaged parts. During the high-speed operation of the train, the impact, dynamic effect and vibration between the vehicle and the rail will cause the train axle to heat up. When the axle temperature rises abnormally, it will cause great damage to the axle, which is a major hidden danger to the safe operation of the train. "Combustion prevention and cutting" is the primary problem that must be solved in the transportation of freight trains. The so-called "cutting" refers to the phenomenon of eagerly cutting the axle due to the temperature rise of the axle, which directly lead...

Problems solved by technology

However, the dynamic monitoring of running vehicles based on the ground monitoring system requires the deployment of many monitoring points along the main railway line. Not only the detection cost is high, the installation and maintenance are cumbersome, but also can only be selected for detection, and dynamic real-time monitoring and Make timely judgments on potential faults

At the same time, the ground monitoring systems are independent of each other, the data cannot be interacted, the monitoring parameters are single, and the ground network wiring is complicated

[0004] With the development of my country's railway transportation industry, the terrain of railway lines is becoming more and more complex, the number of monitoring points required by the ground monitoring system is increasing, the location of monitoring points is often changed, and the monitoring range is becoming wider and wider. The ground monitoring method for freight trains has been unable to meet the requirements. Field Application Requirements
