Monitoring control system for rail transportation

Abstract

The invention relates to a monitoring control system for rail transportation, comprising at least one sensor group arranged at a selected monitoring point of a rail. Each sensor group comprises at least one acting force sensor and one vibration sensor; a rail dynamic signal processing circuit is connected with the sensor group and used for respectively receiving and converting an acting force time-domain signal measured by the acting force sensor of the sensor group and a vibration time-domain signal measured by the vibration sensor, and sending the converted signals to a signal calculating and processing unit; the signal calculating and processing unit comprises an acting force signal time-domain / frequency-domain conversion circuit, a vibration signal time-domain / frequency-domain conversion circuit and a frequency responding function calculating unit, wherein the frequency responding function calculating unit divides a received acting force frequency-domain signal and a received vibration frequency-domain signal to generate an input and output response spectrum signal, therefore, the abnormal status of the rail can be judged according to the input and output response spectrum signal.

Description

technical field [0001] The invention relates to a monitoring technology for rail safety of a transportation system, in particular to a monitoring and control system for rail transportation. Background technique [0002] The rail transportation system plays an extremely important means of transportation for the transportation of people and goods. In addition to the safety of the rail vehicle itself, the structural safety of the track is very important for mass transportation systems. If it is not possible to detect in advance and then maintain and maintain before the structural safety of the track changes, the hazards and accidents it produces will often endanger the lives of passengers. [0003] Most of the track maintenance of the traditional railway system is still done through regular and intensive manpower maintenance. This traditional method not only consumes manpower and material resources, but also has poor reliability. possibility of accident. [0004] In order to...

Problems solved by technology

[0003] Most of the track maintenance of the traditional railway system is still done through regular and intensive manpower maintenance. This traditional method not only consumes manpower and material resources, but also has poor reliability. possibility of accident

[0004] In order to overcome the lack of traditional methods, there have been various monitoring technologies in the previous technologies, but these technologies still cannot meet the current safety requirements of rail transportation in fact.
