Description

High bright LED light filling image acquisition device

Technical Field

The invention relates to a high-brightness LED light supplementing image acquisition device, and belongs to the field of railway train vehicle safety detection systems.

Background

The wheel pair is used as a key bearing part of the locomotive, and the quality of the wheel pair is important for the driving safety. For the detection equipment of the wheel quality in China, the traditional detection means adopts a manual mode, and the detection cannot meet the current requirements in view of low manual detection efficiency and human detection difference of operators. In the current wheel tread scratch, peeling, abrasion and block falling detection at low speed, the image technology is developed in recent years, and the current domestic mainstream technology adopts image vision automatic detection and adopts a measuring device and a wheel online non-contact mode. The automatic picture taking device is usually arranged on a train warehousing line, and is automatic and gradually replaces manual operation, and has the defects that when the picture is taken, the illumination is not uniform, the environment change in the daytime and at night is large, and the quality of the picture taken by the picture taking device cannot be met.

Disclosure of Invention

The utility model aims at providing a high bright LED light filling image acquisition device, it is not enough in the detection of overcoming current equipment. Design a light, reliable, safe detection device, when satisfying train vehicle and advancing, going out of the warehouse, the requirement of the different scenes when passing by daytime and evening, high bright LED light filling image acquisition device can satisfy online real-time detection, improves image quality greatly, improves the light filling performance, remedies evening and the poor problem that causes of daytime environment.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a high bright LED light filling image acquisition device, includes quick-witted case, LED array unit, shoots equipment and control and output unit, LED array unit, the equipment of shooing and control and output unit set up in the quick-witted case, quick-witted case fixed mounting is on the railway rails, control and output unit respectively with LED array unit with the equipment of shooing is connected, LED array unit and the equipment of shooing become 0-90 jiaos with the wheel tread of examining and arrange.

Furthermore, the device also comprises a window protection device which is arranged on the surface of the case and used for protecting the LED array unit and the photographing equipment.

Further, the LED array unit and the photographing apparatus may be disposed at the same side or different sides.

Further, the LED array unit comprises a light source and a light source plate, the LEDs in the LED array unit are arranged in 2 rows of arrays, and the LED arrays are arranged at an angle of 0-180 degrees.

The utility model discloses realize the bright LED light filling image acquisition device of height under the train vehicle running state, compare with prior art, reduce the examined wheel tread effective area of facula radiation to it is dark effectively to compensate the picture that external environment leads to the tread to shoot. Aiming at tread image detection, good image quality provides a good foundation for the later image processing algorithm and the automatic early warning of defects, the detection efficiency and the accuracy are effectively improved, and the result can be quickly checked manually.
