AI Technical Summary

Problems solved by technology

Although more accurate train length and other information can be obtained, the equipment is relatively complex and highly dependent on each other. When a sub-equipment fails, it will affect the accuracy of the final result
Moreover, when the environment is relatively harsh, due to network problems, communication failures between devices may occur

Embodiment Construction

[0039] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] Please combine Figure 1 to Figure 2 As shown, a kind of train wagon quantity and length measurement system based on laser radar provided by the present invention includes:

[0041] The bracket 3 is arranged on the track teeth and is made of stainless steel. The bracket 3 is provided with a plurality of bolt holes along its vertical direction for adjusting the installation height of the laser radar 1 and / or the speed measuring device 2 .

[0042] The laser radar 1 is set on the bracket 3 for real-time acquisition of the contour data passing through the train wagon bracket 4. The laser radar 1 adopts a two-dimensional laser radar, and its scanning angle is α 0 , the effective measurement distance is 10m, and the scanning line 6 of the laser radar 1 is parallel to the carriage 4 of the train wagon.

[0043] The speed me...

Abstract

The invention discloses a train wagon number and length measuring system and method based on a laser radar, and the system comprises laser radar which is used for obtaining the contour data of a trainwagon bracket in real time; a speed measuring device, used for acquiring the speed of the passing train in real time; and an industrial personal computer, used for extracting the contour data, acquired by the laser radar, of the train wagon bracket and the speed, acquired by the speed measuring device, of the train, and carrying out background data processing and result output. According to the invention, the laser radar is utilized to accurately obtain the number and length of train wagons, so that the dynamic carrying information of each trailer carriage is monitored and managed.

Description

technical field [0001] The invention relates to the automatic detection technology of the outline of the carriage of train wagons, more specifically, to a system and method for measuring the quantity and length of train wagons based on laser radar. Background technique [0002] With the rapid development of economy, railway transportation has also made great progress. The length of the train and the dynamic information of each wagon play an important role in the safety management, efficiency optimization and precise scheduling of railway transportation. Under the current management of railway operations, although it has been equipped with a number of equipment and systems, it has also played a certain role in guaranteeing the management of railway transportation. However, for the tracking of the length of the train, the number of wagons, and even the speed of the train, it can only be tracked by manual counting and ground vehicle number identification, etc., and it may be d...
