Abstract

The invention discloses a device and method for detecting a railway boxcar, and the detecting device comprises a fixing rack across the railway track, wherein a frame through the boxcar can run is formed on the fixing rack, a laser radar is disposed on the inner side of the top of the frame and is used to scan the interior of the boxcar with the top opened, and the laser radar transmits the scanning data to a calculation processor. The detection method comprises the following steps of scanning the interior of the boxcar by the laser radar at the same time when the boxcar runs through the fixing rack; performing image acquisition by a high definition array camera and an industrial camera; de-noising the data; processing the de-noised data; determining whether there are conditions of foreignmatters, damages, holes and door opening; and transmitting the detection result. The laser radar in the invention continuously scans the passing boxcars, so as to obtain the size of the interior of the boxcars and detect whether there are foreign matters, holes, doors opening and other problems in the boxcars.

Description

technical field

[0001] The invention belongs to the field of detection of railway freight car compartments, and in particular relates to a detection device and a detection method for railway freight car compartments. Background technique

[0002] In domestic transportation, railways are the backbone and main force of bulk cargo transportation. Freight trains have many carriages, and relying solely on manual inspection and survey work is heavy and difficult. It brings many inspection results and management and maintenance problems. Therefore, an efficient and intelligent safety assessment and scientific maintenance system is urgently needed.

[0003] Chinese patent CN201810295593.7 discloses a method for detecting abnormal behavior of carriages, but the abnormal behavior detection of this carriage is only suitable for the detection of passenger behavior on passenger trains, and is not suitable for freight trains.

[0004] In addition, Chinese patent CN201611255261.3 disclos...

Embodiment Construction

[0044] Below, the present invention is described in detail with reference to accompanying drawing and embodiment:

[0045] Such as Figure 1~3 As shown, a detection device for railway wagon carriages includes a fixed mount 10, the fixed mount 10 straddles the railway track, a frame through which the wagon carriage 11 can pass is formed in the fixed mount 10, and the inside of the top of the frame is set There is a laser radar 1 that scans the interior of a truck compartment 11 with an open top, and transmits the scanned data to a computing processor 2 .

[0046] The fixed frame 10 is provided with a camera assembly capable of taking pictures of the outside and inside of the truck compartment 11 .

[0047] The camera assembly includes a high-definition area-scan camera 4 for taking pictures of the inside of the truck compartment 11 , and the high-definition area-scan camera 4 is arranged on the outer sidewall of the top beam of the fixing frame 10 .

[0048] The camera assemb...
