Embodiment 1

[0052] Example 1, such as figure 1 As shown, the UAV railway line inspection system includes UAV 1 , UAV controller 2 , camera 3 , controller 4 , and display 5 .

[0053] The UAV 1 is used to patrol the railway lines outside the tunnel, and the UAV controller 2 is installed on the UAV 1 to control the flight route, flight trajectory, and flight attitude of the UAV 1 in real time. During the inspection process, UAV 1 encounters a passing train, and can keep the original position and wait according to the parameters set by UAV controller 2. After the train runs, it will continue to patrol according to the flight attitude set by UAV controller 2. This can ensure the safety of the UAV 1 in the inspection process.

[0054] There are at least two groups of cameras 3, at least one group is installed on the UAV 1, at least one group is installed in the railway tunnel, the camera 3 is mainly used to collect on-site image data of the railway line, and the on-site image data includes th...

Embodiment 2

[0057] Embodiment 2, different from above-mentioned embodiment 1, this device also comprises mobile phone detection system, and mobile phone detection system is installed on the movable smart device, is used for viewing the monitoring result of monitoring module 43, facilitates monitoring personnel to check at any time, makes monitoring The personnel can organize personnel to repair or deal with the abnormal situation of the railway line in time. Abnormal conditions include catenary and its accessories, rails, rail foundations, track slabs, track beds, and track fasteners, such as cracks, breaks, falling off, loosening, off-line, and protrusions that affect train driving safety.

[0058] image 3 It is a flowchart of the inspection method of the present invention, Figure 4 It is a flowchart of a method for processing images of railway lines in an embodiment of the present invention, Figure 5 It is a flow chart of the method for judging whether there is a fault point in the...

Abstract

The invention relates to a UAV (Unmanned Aerial Vehicle) railway line inspection device, system and method. The device comprises a UAV, a UAV operator, at least two sets of cameras, a controller and a display; the UAV operator is installed on the UAV; at least one set of cameras is installed on the UAV; at least one set of cameras is installed in a railway tunnel; the cameras are used for acquiring field image data of railway lines; the field image data comprises images and coordinates of the railway lines; the controller is connected with the cameras, and used for receiving, processing and monitoring the field image data acquired by the cameras; the controller is connected with the UAV operator, and used for controlling the UAV operator to set flight parameters of the UAV; and the display is used for displaying the image data output by the controller. By means of the UAV railway line inspection device, system and method disclosed by the invention, the railway lines inside and outside the tunnel can be inspected; furthermore, post processing and monitoring of the acquired image data can be carried out; and thus, failure points of the railway lines can be judged and located more accurately.

Description

technical field [0001] The invention relates to the field of railway line inspection, in particular to an unmanned aerial vehicle inspection device, system and method for railway lines. Background technique [0002] In the railway bureau system, to ensure the safety of railway traffic, railway line inspection is an indispensable daily work. At present, the existing inspection of railway lines relies entirely on the way that railway line inspection workers inspect the railway tracks along the railway line. This inspection method has huge limitations and defects. For example, inspection workers inspect a 1-kilometer railway line It takes about 1 hour, resulting in a long inspection time; inspections are still required in harsh environments such as rain, ice, snow, and high temperature, resulting in high labor intensity for inspection workers; during inspections, trains often pass by inspection sites, etc. , there are unsafe factors. Therefore, this inspection method is no lo...
