Problems solved by technology

Experiments show that this data projection method cannot clearly distinguish typical fault conditions such as anti-snaking shock absorber faults, anti-lateral displacement shock absorber faults, and air spring faults of high-speed trains at low speeds, and there are blind spots in real-time monitoring. Can not achieve full speed range monitoring, there are certain hidden dangers

Embodiment Construction

[0020] Below in conjunction with specific embodiment and accompanying drawing, the present invention is further described:

[0021] like figure 1 As shown, a train running state monitoring system based on data projection mode change includes a data acquisition module, a data processing module, and a monitoring module. The data acquisition module used to collect acceleration and displacement is equipped with a pre-130Hz low-pass filter circuit, an acceleration sensor and a displacement sensor. The above two sensors are installed on the train body, the upper floor of the body bolster, the frame, the axle gearbox, etc. ; The data processing module for processing the collected data includes an arithmetic unit for data calculation and a memory for data storage; the monitoring module is a terminal display or a fault discriminator. The sensor filters the collected data through a pre-filtering circuit, and then transmits the data to an arithmetic unit. The arithmetic unit processes t...

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...
