Embodiment 1

[0053] see Figure 1-3 A high-speed railway track condition dynamic detection system and method, comprising a mechanical module, a transmission module, and a software module; the mechanical module includes laid rails, sleepers, fasteners; the transmission module includes a plurality of sensors, data acquisition cards , an industrial camera, an industrial computer; the software module includes a rail measurement submodule and a component image analysis submodule; the industrial computer obtains signals from the data acquisition card through serial communication, and the sensor and the data acquisition card are connected via an infinite Signal transmission.

[0054] A plurality of said sensors are respectively arranged on the position near the base of the rail, and said sensors are laser displacement sensors; when the train runs at high speed, it is used to detect the thickness of the rail (in image 3 Indicated by the letter Y), width (in image 3 Indicated by the letter X), ...

Embodiment 2

[0066] see Figure 1-3 A high-speed railway track condition dynamic detection system and method, comprising a mechanical module, a transmission module, and a software module; the mechanical module includes laid rails, sleepers, fasteners; the transmission module includes a plurality of sensors, data acquisition cards , an industrial camera, an industrial computer; the software module includes a rail measurement submodule and a component image analysis submodule; the industrial computer obtains signals from the data acquisition card through serial communication, and the sensor and the data acquisition card are connected via an infinite Signal transmission.

[0067] There are 4 laser displacement sensors, and the data collected are transmitted to the industrial computer for data processing, including the following steps:

[0068] a: Remove abnormal values ​​caused by misjudgment of track position, strong light reflection and human operation;

[0069] b: Remove the low-frequenc...

Embodiment 3

[0073] The difference from Embodiments 1 and 2 is that the dynamic detection method of a high-speed railway track condition includes the following steps:

[0074] S1; data acquisition, when the train is running, the sensor collects the thickness, width, height, profile and other data of the rail;

[0075] S2; data storage, the set database is divided into a configuration database and a unit database, each sensor corresponds to a unit database, and the configuration database stores relevant configuration information;

[0076] S3; data analysis, analyzing the collected rail data, analyzing the collected rail and fastener pictures;

[0077] S4; data comparison, the data after S3 analysis is compared with the original data of the rail components, and the health status of the rail components is judged;

[0078] S5: Fault display. After the diagnosis result is obtained, the fault type is displayed through the industrial computer, the cause and solution of each fault are given, and ...

Abstract

The invention discloses a dynamic detection system for a high-speed railway track condition. The dynamic detection system comprises a mechanical module, a transmission module and a software module, the mechanical module comprises laid steel rails, sleepers and fasteners. The transmission module comprises a plurality of sensors, a data collection card, an industrial camera and an industrial personal computer; the software module comprises a steel rail measurement sub-module and a component image analysis sub-module; the industrial personal computer acquires signals from the data collection cardin a serial communication mode, and the sensors and the data collection card are in wireless signal transmission; by dynamically detecting the geometrical states of steel rails, steel rail connectingfasteners, sleepers and other components of the rail, the reliability of rail detection is effectively improved, and the stability of the rail is further improved.

Description

technical field [0001] The invention belongs to the technical field of track detection, and in particular relates to a system and method for dynamic detection of high-speed railway track conditions. Background technique [0002] Railway is the lifeblood of national economic construction, plays an important role in my country's economic construction, and is also an important means of travel; on the other hand, urban rail transit is also developing rapidly. The rapid development of China's railways and urban rail transit has a great impact on the safety of rail lines The state puts forward new requirements. The safety and comfort of rail traffic are affected by many factors. Among them, the track irregularity is an important factor affecting the safety and comfort of locomotives. When the train passes, the track irregularity not only increases The impact force will accelerate the deformation of the track structure of the ballast bed, which has a great impact on the smooth operat...
