Acquiring device capable of comprehensively perceiving rail appearance condition

Abstract

The invention provides an acquiring device capable of comprehensively perceiving a rail appearance condition. The acquiring device comprises two linear array cameras, two area array cameras, a frequency division plate, two LED light sources, a light source control box and a comprehensive power source; the comprehensive power source is respectively connected with the two linear array cameras, the two area array cameras, the frequency division plate, the two LED light sources and the light source control box by using wires; the two linear array cameras are respectively connected with the frequency division plates by using signal lines and are used for receiving a signal of the frequency division plate and imaging the obverse sides of a steel rail, a fastener and a rail board on a rail; the two area array cameras are connected with the light source control box by using signal lines and are used for acquiring open joint images at the side of the rail; the light source control box is respectively connected with the two LED light sources by using wires and is used for controlling the LED light source to supplement light according to signals of the area array cameras; and the two linear array cameras and the two area array cameras are respectively provided with industrial personal computer interfaces. By using the acquiring device, the comprehensive perception of the rail appearance condition can be realized.

Description

technical field [0001] The invention relates to the technical field of railway tracks, in particular to a collection device for comprehensive perception of track appearance and state for detecting tracks. Background technique [0002] With the rapid development of the railway industry, the speed of trains is getting faster and faster, and higher requirements are put forward for the safety of the track system. Track inspection has become the top priority to ensure railway safety. At present, the inspection method of the track is mainly manual inspection or manual trolley inspection. Manual inspections are highly repetitive and work-intensive, and the inspection results are easily affected by subjective and objective factors such as the level of inspection workers, weather and light, and the accuracy of inspections is difficult to guarantee. [0003] With the continuous advancement of my country's railway construction, the railway line is getting longer and longer, and the am...

Problems solved by technology

Baoji CSR Times Construction Machinery Co., Ltd. has developed a rail multi-functional inspection and flaw detection vehicle. The vehicle body is composed of a tractor and an inspection vehicle, and the flexibility of operation is relatively weak. Sichuan Duojizi Technology Co., Ltd. has developed a fully automatic train rail loss image Acquisition device, which has a high degree of automation, but cannot obtain images of key parts including track plates

Chinese patent literature has a kind of track detection instrument (application publication number CN107585172A) that can walk automatically, and the car body is provided with the tight wheel that contacts with rail inner surface and the running wheel that contacts with rail top surface, can set on track Automatically move forward at a fixed speed and uniform speed, realizing detection while moving, but cannot detect the environment around the track

Based on this, it can be found that most of the current automated imaging inspection equipment based on computer vision technology is complex in structure and expensive in cost, and in order to collect a single-view image to detect a specific type of rail defect, it cannot detect rail surface scratches and fastener defects at the same time. , track slab cracks, track slab and base gaps and other track appearance defects for imaging detection, it is difficult to meet the requirements of comprehensive inspection of modern railway operating environment
