Embodiment 1

[0060] like figure 1 As shown, a method for dynamic detection of high-speed railway track conditions, comprising the following steps:

[0061] S1; data acquisition, when the train is running, the thickness of the rail and sleeper is collected by the sensor (in Figure 4 Indicated by the letter Y), width (in Figure 4 Indicated by the letter X), height (in Figure 4 Indicated by the letter Z), outline and other data;

[0062] 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;

[0063] S3; data analysis, analyzing the collected rail data, analyzing the collected rails, fasteners, and sleeper pictures;

[0064] 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;

[0065] S5: Fault display. After the diagn...

Embodiment 2

[0077] see figure 2 , 3 , shown in 4, a kind of high-speed railway track condition dynamic detection system, comprises mechanical module, transmission module, software module; Described mechanical module comprises the steel rail that lays, sleeper, fastener; Described transmission module comprises a plurality of sensors, data Acquisition card, industrial camera, 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 Transmission via unlimited signal.

[0078] A plurality of the sensors are respectively arranged at the position close to the base of the rail, and the sensors are laser displacement sensors; when the train is running at high speed, the data used to detect the thickness, width, height, and contour of the rail are transmitted to the data acquisition card.

[0079] An industrial camera is ins...

Embodiment 3

[0087] see figure 2 , 3 , shown in 4, a kind of high-speed railway track condition dynamic detection system, comprises mechanical module, transmission module, software module; Described mechanical module comprises the steel rail that lays, sleeper, fastener; Described transmission module comprises a plurality of sensors, data Acquisition card, industrial camera, 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 Transmission via unlimited signal.

[0088] There are 4 laser displacement sensors, and the data collected are transmitted to the industrial computer for data processing, including the following steps:

[0089] a: Remove abnormal values ​​caused by misjudgment of track position, strong light reflection and human operation;

[0090] b: Remove the low-frequency trend term brought by the elev...

Abstract

The invention discloses a dynamic detection method for high-speed railway track conditions. The method comprises the following steps: S1, data acquisition: thickness, width, height, outline and otherdata of steel rails and sleepers are acquired through sensors when a train runs; S2, data storage: a set database is divided into a configuration database and unit databases, each sensor corresponds to one unit database, and the configuration database stores related configuration information; S3, data analysis: the acquired steel rail data is analyzed, and acquired pictures of the steel rails, fasteners and the sleepers are analyzed; S4; data comparison: the data analyzed in S3 is compared with the original data of the steel rail components, and the health condition of the steel rail components is judged; and S5; fault display: after a diagnosis result is obtained, the fault type is displayed through an industrial personal computer. By dynamically detecting the geometrical states of steelrails, steel rail connecting fasteners, 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 dynamic detection method for 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 operation of the tra...
