The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-4, the utility model discloses a switch on-site detection device, including the shell and setting up two mesh cameras and the laser instrument in the shell inside, the hollow region in the shell is set up to include two mesh camera fixed areas, laser emitter fixed area, power module fixed area and industry control module fixed area; the laser emitter fixing area comprises a first side surface and a laser emitting plane, and an emitting port of the laser emitter emits laser along the direction vertical to the laser emitting plane through a through hole arranged on the laser emitting plane; the binocular camera fixing area comprises a second side face, a third side face and a camera shooting plane, and the lens of the binocular camera shoots along the direction vertical to the camera shooting plane through two parallel through holes arranged on the camera shooting plane; wherein an included angle between the laser emission plane and the second side surface is larger than 90 degrees. In order to ensure the quality of image information shot by the device, the included angle between the perpendicular bisector of the two lenses of the binocular camera and the extension line of the turnout needs to be ensured to be 45 degrees when the device is used, and the distance between the perpendicular bisector of the two lenses of the binocular camera and the stock rail is 0.2-0.3 m. The accuracy of the installation position of the device directly influences the quality of image information, and further has great influence on the analysis of the switch point deformation index. However, auxiliary tools are needed to directly measure the angle and the distance between the binocular camera and the stock rail, and other auxiliary equipment is needed to measure the angle and the distance again if the position of the device needs to be rearranged in the subsequent use process. In order to realize the quick positioning and installation of the device, the device adopts the laser emitter to emit collimated laser to the stock rail direction, and because the relative angle between the shooting direction of the lens of the binocular camera and the laser emitting direction is fixed, the relative position and angle of laser ray irradiation are determined, and the relative position and angle between the shooting angle of the binocular camera and the stock rail can be indirectly determined. Further, the laser emitted by the laser emitter irradiates the center of the overlapped part of the two lens shooting areas of the binocular camera. In the present embodiment, as a preferred embodiment, the included angle between the laser irradiation plane and the second side surface is set to 100 °, the side length of each surface is as shown in fig. 4, the side length of the laser emission plane is 70.39mm, the side length of the camera shooting plane is 190mm, the side length of the first plane is 140mm, the side length of the second plane is 68.23mm, and the side length of the third plane is 59.51 mm.
