Road-rail dual-mode-vehicle automatic rail alignment system and method thereof, and fire fighting truck

Abstract

The invention relates to the road-rail dual-mode-vehicle technology field and discloses a road-rail dual-mode-vehicle automatic rail alignment system and a method thereof, and a fire fighting truck. The road-rail dual-mode-vehicle automatic rail alignment system comprises a visual detection device, a driving device, an angle detection device and a control module, wherein the visual detection device is installed on a tail portion of a vehicle body and is used for collecting a rail image; the driving device is used for driving the visual detection device and a rear wheel rail of a vehicle to rotate; the angle detection device is used for detecting rotation angles of the visual detection device and a rear wheel of the vehicle; and the control module is used for making the driving device drive the visual detection device to rotate to a detection direction of the visual detection device according to the collected rail image so as to form a predetermined angle with the rail, recording a rotation angle alpha and a rotation angle direction of the visual detection device, and making the rear wheel rail of the vehicle rotate according to the rotation angle alpha and the rotation angle direction so that the rear wheel rail of the vehicle is parallel to the rail. In the invention, road-rail dual-mode-vehicle automatic rail alignment is realized, rail alignment time is shortened and rail alignment efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of dual-purpose rail vehicles, in particular to an automatic rail alignment system and method for dual-purpose rail vehicles and a fire truck. Background technique [0002] figure 1 is a side view of an existing rail vehicle, figure 2 It is the bottom view of the existing rail vehicle. Such as figure 1 with figure 2 As shown, the road-rail vehicle has a road travel system 1 and a rail travel system, wherein the rail travel system is composed of a front wheel rail 2 and a rear wheel rail 3 . The road running system 1 is used for running on the road like ordinary vehicles, and the track running system utilizes hydraulic drive to realize the running of the vehicle on the track. Because in the subway and other tracks, the vehicle is more in line with the characteristics of the space by reversing on the rail, so the rear wheel rail needs to be placed on the rail first. angle. But at present, whether it i...
