Abstract

The invention discloses a train operation state monitoring system based on data projection mode conversion. The train operation state monitoring system comprises a data collecting module, a data processing module and a monitoring module. The data collecting module comprises a sensor for collecting data and a pre-filtering circuit. The data processing module comprises an arithmetic unit used for data calculation and a storage device used for data storage. The arithmetic unit processes the data according to the mode that multiple characteristic data are projected at the same time. The sensor transmits the collected data filtered by the pre-filtering circuit to the arithmetic unit, and the arithmetic unit processes the characteristic data in the mode of one-data-point projection and then transmits the data to the storage device and meanwhile transmits the data to the monitoring module. The train operation state monitoring system is simple in structure and data processing algorithm, free of calculation which is complex, large in time and resource consumption and expenditure and capable of meeting the requirements for real-time performance, instantaneity and timeliness of monitoring performed on safety and comfort of train operation.

Description

technical field

[0001] The invention belongs to the field of signal monitoring and processing, relates to a train running state monitoring system, in particular to a train running state monitoring system based on data projection mode transformation. Background technique

[0002] With the development of railway construction in China, high speed and heavy load have become the dominant trends in the development of trains, and the requirements for the safety and comfort of train operation are getting higher and higher. There is an increasing demand for diagnosing train failures and finding faulty components.

[0003] At present, some fault identification and fault identification of high-speed trains have been transformed from traditional manual detection to automatic processing by intelligent systems. The current intelligent system compares the acceleration value or displacement value of a specific part of the train measured at different operating speeds and different operating...
