[0030] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Refer to the attached Figure 1 -Attached Figure 6, a railway track online mobile detection system and method provided by the present invention comprises a detection management platform module 1, a signal processing module 2 is provided at a connection end of the detection management platform module 1, a data processing module 3 is provided at a connection end of the signal processing module 2, the signal processing module 2 comprises a track geometry parameter detection management module 4, a track fastener detection module 5 and a foreign body detection module 6, the track geometry parameter detection management module 4 comprises a track height detection module 7, a track gauge detection module 8, a track direction detection module 9, a horizontal detection module 10 and a triangular pit detection module 11, the detection management platform module 1 is data-connected with the signal processing module 2, the signal processing module 2 is data-connected with the data processing module 3, the signal processing module 2 is respectively data-connected with the track geometry parameter detection management module 4, the track fastener detection module 5 and the foreign body detection module 6, the track geometry parameter detection management module 4 is respectively data-connected with the track height detection module 7, the track gauge detection module 8, the track direction detection module 9, the horizontal detection module 10 and the triangular pit detection module 11;

[0032] In this implementation scheme, due to the instantaneous increase in impact force, the vertical acceleration of the vehicle body is generated, the deformation of the ballast bed and track structure is accelerated, and other factors such as ballast bed collapse, mud overflow, and sleeper hanging are added, resulting in uneven height of the rails. The track height detection module 7 uses a laser rangefinder to detect the height and smoothness of the tracks on both sides. The track structure is poor due to fat edges, hard bends, uneven side wear of curves, and failure of sleepers. The geometric dimensions are poor due to over-limit of track gauge, uneven gauge decrease, crushing of large rubber pads at the bottom of the rail, and continuous large-scale deflection. The above causes the track gauge to change. The track gauge is detected by the track gauge measuring ruler of the track gauge detection module 8. Due to the poor track direction, horizontal acceleration is easily generated, which causes the train wheels to be subjected to lateral impact, causing the vehicle to sway left and right and the body to shake and vibrate, resulting in the expansion of the track gauge in the curved section, serious wear of the upper rail, and accelerated deformation of the track structure and the roadbed. The track displacement data is collected by the sensor on the wheel of the track direction detection module 9, and then the deviation of the track direction is obtained by using the data analysis method. When the rail level is inconsistent, it will cause the vehicle to tilt and roll, which is easy to The vehicle body sways laterally and triangular pits occur. The horizontal detection module 10 uses an electronic level to detect the horizontal data of the rails. The uneven hardness of the ballast, whitening, slurry and untimely maintenance of line equipment due to poor weld quality, excessive rail seams, loose joint bolts, wear of splints, and scratches on the rail top surface all lead to uneven leveling, whitening, and mudding, which in turn lead to the appearance of triangular pits. The triangular pit detection module 11 uses a laser beam emitted by a laser of a track inspection vehicle to form a laser point between the wheel, tire and track. A high-precision measuring instrument will accurately measure the laser point to obtain the geometric shape and wheel type parameters of the wheel surface. By analyzing the wheel surface data, the triangular pits on the wheel surface can be identified, and the shape, depth and position of the triangular pits can be measured. The foreign body detection module 6 obtains the cross section above the track through a laser scanner to determine whether there is foreign body intrusion. The signal processing module 2 connects the detection equipment signal and establishes a channel for the transmission of the detection data. The data processing module 3 analyzes and processes the detection data and marks abnormal data.

[0033] Among them, in order to achieve the purpose of data monitoring, the present device is implemented by the following technical solutions: the track geometry parameter detection management module 4 includes an image monitoring module 12, a laser photoelectric monitoring module 13 and an ultrasonic monitoring module 14, and the track geometry parameter detection management module 4 is respectively connected with the image monitoring module 12, the laser photoelectric monitoring module 13 and the ultrasonic monitoring module 14. Through the laser photoelectric monitoring module 13, the image monitoring module 12 needs to use image solution technology to solve the detection when the railway line is in a dynamic and static state during the normal detection process, and timely discover the problem of track unevenness. The image solution technology will be used to detect the state of the track components to avoid the derailment of the track components, such as the breakage of the track fishtail plate, the wear of the rails, and the collapse of the roadbed. The railway line is fully inspected to improve the quality of the railway line equipment. The laser photoelectric monitoring module 13 can use laser light when the track line is in a dynamic and static state. The electrical detection technology can comprehensively and scientifically measure whether the geometric shape and position of the track have changed, and timely check whether the track width has changed. Using the laser principle, the laser equipment emits laser directly on the rail line. Through reflection, the light can be reflected on the linear scanner through the rail line, so that the light spot position can be planned, the rail line position and the emerging fault point can be planned. The ultrasonic monitoring module 14 uses ultrasonic flaw detection technology to detect the rails in the dynamic and static inspection of the railway line. It can effectively use ultrasonic waves to produce reflection, refraction and waveform conversion on heterogeneous interfaces, and can accurately check certain problems on the rails. Through ultrasonic flaw detection technology, high-frequency sound waves are emitted by the equipment, and the sound waves are transmitted between the railways. Through the air interface, cracks in the rails can be found, and the data can be transmitted to the computer system through the sound wave reflection. The data is displayed according to the received signal wave intensity to detect whether the rails have defects and the precise location of the defects.
