Embodiment 1

[0055] Such as figure 1 , 2 , 3 shown.

[0056] The three-coordinate monitoring device for the offset between the track and the roadbed includes: a plane image marker 1 fixedly connected to the roadbed 11; a camera 2 fixedly connected to the track 12; a power supply device 7 for powering the camera; The cover outside the object prevents the camera and the plane image marker from being blocked by rain, snow or dust; the ambient light source around the camera; the control board 6; the wireless communication module 4; the acceleration monitoring module 5; the camera, the ambient light source, the wireless communication The module and the acceleration monitoring module are all connected to the control board, and the power supply device supplies power for the control board, the camera, the ambient light source, the wireless communication module, and the acceleration monitoring module;

[0057] In the initial installation position, the optical axis of the camera is perpendicular t...

Embodiment 2

[0081] Such as figure 2 , 3 , 4 shown.

[0082] The three-coordinate monitoring device for track and roadbed offset includes: a plane image marker 1 fixedly connected to the track 12; a camera 2 fixedly connected to the roadbed 11 through a bracket 13; the difference from Embodiment 1 is that the camera is connected to the roadbed, and The image marker is connected with the track, and the camera is lifted by the bracket, which is higher than the height of the image marker, and this design is conducive to the implementation of waterproofing. Other content is identical with embodiment 1.

Abstract

The invention relates to a track and roadbed deviation three-coordinate monitoring device and method. The monitoring device comprises a plane image marker 1, a camera 2 and a power supply device 7 providing power for the camera, wherein the plane image marker 1 and the camera 2 are respectively arranged on a track and a roadbed; at the initial installation position, the optical axis of the camerais perpendicular to the plane image marker. According to the invention, displacement offsets of three dimensions can be monitored on line at the same time, so that the workload of arranging sensors ona track is reduced; the camera is fixedly connected with the roadbed, the roadbed has relative stability, so that the camera is affected by vibration as little as possible, the imaging quality is ensured, and the service life of the camera is prolonged. Only one plane image marker needs to be bonded to the track, the stress structure of the track cannot be damaged, a complex process technology isnot needed, and on-site construction of track engineering is facilitated.

Description

Technical field: [0001] The invention relates to rail transit online monitoring technology, in particular to a three-coordinate monitoring device and method for track and roadbed offset track and roadbed offset. Background technique: [0002] The emergence of railway technology is one of the greatest innovations in modern times. With the improvement of railway carrying capacity and train speed, the change of track stress caused by factors such as temperature difference has become an important factor affecting railway safety. Especially in recent years, ballastless track technology has been widely used in high-speed railway foundations. Ballastless track consists of three parts from top to bottom: seamless steel rail, track slab, and rigid foundation commonly known as roadbed. When the rail will deviate along the direction of the rail due to braking, when the temperature difference of the surrounding environment or other external factors such as the debris flow movement of th...
