Problems solved by technology
Since the train is composed of a group of multi-section vehicles, there are buffer devices and coupler connection gaps at the vehicle joints. These factors cause a certain error in the length of the vehicle. This error is a function of vehicle traction, propulsion, speed, braking force, acceleration , Weight-related changes, the distance between the rail tractor and the vehicle to be loaded and unloaded has a large error during the operation of the rail tractor, and the more the number of vehicles in the train, the greater the error accumulation. These errors do not meet the loading and unloading equipment operations Accuracy requirements

Embodiment Construction
[0063] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0064] It should be noted that the process of rail-water combined transport can be briefly described as: a train train is composed of several connected vehicles. During the unloading and loading process, the railway train train is a group of empty cars, and one of the empty cars is parked on the quay bridge spreader. Within the operating range (for example, the error is within ±200mm), the designated connection position is waiting for loading. The quay crane sp...

The invention provides a rail and water combined transport railway vehicle tracking and positioning method and system, and belongs to the technical field of tracking and positioning. The rail and water combined transport railway vehicle tracking and positioning method comprises the steps that vehicle numbers, vehicle models and the like of vehicles are collected; a first rail track rough distanceis calculated; the first rail track rough distance from a target carriage to a motor tractor center under a shore bridge is obtained; a carriage to be loaded and unloaded is determined, and a second rail track rough distance from the carriage to be loaded and unloaded to the motor tractor center is obtained; a distance difference value between the second rail track rough distance and the first rail track rough distance is obtained; and a first distance from one ends of the vehicles to the quay crane center and a second distance from the other ends of the vehicles to the quay crane center are calculated, and a traction distance is adjusted. By applying the rail and water combined transport railway vehicle tracking and positioning method and system, through twice image acquisition, twice distance calculation and adjustment are correspondingly carried out, a motor tractor is started again for adjustment according to the adjusted distance, the operational accuracy rate is improved, and thus the accuracy of positioning operation and loading and unloading operation efficiency of a shore bridge lifting appliance in rail and water combined transport are improved.
Description
technical field [0001] The invention relates to the technical field of a track vehicle tracking and positioning system for rail-water combined transport, in particular to a tracking and positioning method and system for rail-water combined transport rail vehicles. Background technique [0002] Rail-water combined transport is an important development direction of modern logistics development. Container rail-water combined transport is an important part of rail-water combined transport. By placing containers in vehicles, containers are used as transport units to improve transport efficiency. [0003] In the prior art, for example, the patent title is container position detection method and device for loading and unloading cranes, and container landing and detection control method, by processing the image of the object container obtained from the camera device such as CCD installed on the spreader data to realize the relative position detection between the object container and...
