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 ...
