Problems solved by technology
[0004] At present, most railway vehicle positioning systems use the track circuit positioning method, but this method can only locate the track section where the railway vehicle is located, so it cannot locate the specific position of the railway vehicle on this section of the track section, so the error range is large, and the positioning low precision

The invention provides a railway vehicle positioning system. The system comprises a vehicle number identification subsystem, which is used for transmitting the obtained vehicle information of each railway vehicle to a monitoring subsystem. A rangefinder at one end of the track line for detecting a first distance and sending the first distance to a monitoring subsystem; A rangefinder at the other end of the track line for detecting a second distance and transmitting the second distance to the monitoring subsystem; The monitoring subsystem is used for determining the standard length of the object to be positioned by using the information to be monitored, calculating the railway mileage coordinates of the object to be positioned based on the standard length, the first distance and the seconddistance, and completing the positioning of the object to be positioned, wherein the information to be monitored is obtained by integrating the vehicle information with the same detection time in thevehicle information. Applying the embodiment of the invention, the positioning accuracy of the object to be positioned is improved.
Description
technical field [0001] The invention relates to the technical field of passive vehicle positioning, in particular to a railway vehicle positioning system. Background technique [0002] Railway transportation is a transportation method that uses railway trains to transport goods, which is characterized by large transportation volume, high speed and low cost. The types of railway transportation can be divided into three types: vehicle transportation, less-than-truckload transportation and container transportation. Among them, the use of container transportation can reduce the loss and loss of goods and ensure the quality of transportation, which is an important direction for the development of cargo transportation. [0003] In the process of container transportation, it is necessary to load and unload the container. In order to realize the automation of the loading and unloading operation, it is necessary to accurately position the railway vehicle loaded with the container. ...
