[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0031] See also Figure 1 , which is a structural schematic diagram of the straddle-type monorail structure defect inspection device provided by the utility model.

[0032] According to the diagram, the straddle-type monorail structural defect inspection device provided by the utility model includes five components: a movable trolley, a lighting component 300, an image acquisition component 400, a processing component 500, and a position acquisition component 600.

[0033] Among them, the movable trolley is the structural main body of this solution, which is used to carry other components. It is arranged on the track beam and can move along the track beam.

[0034] The lighting component 300, the image acquisition component 400, the processing component 500 and the position acquisition component 600 are all arranged on a movable vehicle.

[0035] The lighting component 300 and the image acquisition component 400 are arranged at the front end of the movable vehicle, and the two cooperate with each other. The lighting component 300 emits a light source to illuminate the track beam, and the image acquisition component 400 acquires images of the track beam.

[0036] The image acquisition component 400 and the position acquisition component 600 are respectively connected to the processing component 500. The image acquisition component 400 and the position acquisition component 500 are respectively used to acquire images of the track beam and acquire position information of the movable vehicle and send them to the processing component 500.

[0037] The processing component 500 can associate the image data with the location data and recognize the image.

[0038] The image acquisition component 400 in the straddle-type monorail structural disease inspection device provided by the utility model is in a dormant state when the movable trolley is stationary, and the image acquisition component 400 can be triggered based on the movement of the movable trolley to form a working state;

[0039] In actual application, the position acquisition component 600 can trigger a signal based on the movement of the movable vehicle and output it to the processing component 400 . The processing component 400 controls the image acquisition component 400 to acquire images based on the trigger signal of the position acquisition component 600 .

[0040] The movable trolley includes a vehicle body 100 and an external auxiliary frame 200. A plurality of wheels 130 for moving on the track beam are provided at the bottom of the vehicle body 100. The external auxiliary frame 200 is connected to the outside of the vehicle body 100. The external auxiliary frame 200 is located on both sides of the track beam and auxiliary wheels 230 are provided between the external auxiliary frame 200 and both sides of the track beam.

[0041] Specifically, the vehicle body 100 is rectangular in shape as a whole, and a control system 110, a power supply system 120 and a drive system are arranged inside the vehicle body;

[0042] The driving system is respectively connected to the wheels 130 at the bottom of the vehicle body 100, the control system 110 is connected to the driving system, and the power supply system 120 is respectively connected to the control system 110, the driving system, the lighting component 300, the image acquisition component 400, the processing component 500 and the position acquisition component 600 to provide working power for the above components;

[0043] The power supply system 120 is preferably a 50,000 mAh lithium battery, which is packaged inside the vehicle body 100 and is used to power the entire device.

[0044] The vehicle body 100 is arranged on the track beam through the wheels 130 at the bottom. Through the control of the control system 110, the driving system can drive the wheels 130 to rotate so that the movable vehicle moves along the laying direction of the track beam.

[0045] The vehicle body 100 of such a structure is connected with the external auxiliary frame 200, and the external auxiliary frame 200 provides auxiliary support for the movement of the vehicle body 100. Since the external auxiliary frame 200 is located on both sides of the track beam and auxiliary wheels 230 are arranged between the two, the displacement of the vehicle body 100 perpendicular to its moving direction can be limited, and the vehicle body 100 can be prevented from falling off the track beam.

[0046] like Figure 2 , Figure 3 The external auxiliary frame 200 includes four vertical poles 210, which are respectively located vertically at the four corners of the vehicle body 100 and at both sides of the track beam. Adjacent vertical poles 210 are connected by a cross bar 220, and the cross bar 220 is connected to the vehicle body 100;

[0047] An auxiliary wheel 230 is provided between the vertical pole 210 and the side wall of the track beam. The auxiliary wheel 230 is rotatably connected to the vertical pole 210 and contacts the side wall of the track beam. The auxiliary wheel 230 rotates synchronously with the wheel 130 .

[0048] The external auxiliary frame 200 of such a structure is respectively connected with the lighting component 300 and the image acquisition component 400. The lighting component 300 and the image acquisition component 400 are connected to the front end of the external auxiliary frame 200. With the cooperation of the two, the lighting component 300 can emit a light source to illuminate the collected track beam, thereby ensuring that the image acquisition component 400 captures a clear image.

[0049] The lighting assembly 300 is used for auxiliary lighting during image acquisition, and includes a first LED lamp 310 and a second LED lamp 320 .

[0050] The first LED lamp 310 and the second LED lamp 320 are symmetrically arranged at the top ends of the two vertical poles 210 located at the front end of the external auxiliary frame 200 .

[0051] The image acquisition component 400 is three CMOS cameras, which are used to collect images of the track beam surface. The CMOS cameras are installed on the external auxiliary frame 200. The external auxiliary frame 200 is connected and fixed to the vehicle body 100 and moves synchronously with the vehicle body 100. The three CMOS cameras respectively collect the surface conditions of the front and two side surfaces of the track beam.

[0052] Specifically, the image acquisition component 400 includes a first CMOS camera 410, a second CMOS camera 420 and a third CMOS camera 430. The first CMOS camera 410 is arranged in the middle of the crossbar 220 between the two vertical poles 210 at the front end of the external auxiliary frame 200 and faces the front of the track beam. The second CMOS camera 420 and the third CMOS camera 430 are symmetrically arranged on the two vertical poles 210 at the front end of the external auxiliary frame 200 and face the two sides of the track beam respectively. The first CMOS camera 410, the second CMOS camera 420 and the third CMOS camera 430 are preferably connected to the processing component 500 by wire, so as to transmit the collected images to the processing component 500 for processing;

[0053] By adopting the above structural solution, it is possible to collect all-round images of the track beam and avoid the situation where there are blind spots in the field of vision.

[0054] The image acquisition component 400 of such a structure cooperates with the position acquisition component 600. The position acquisition component 600 is a trigger device of the image acquisition component 400. When the movable vehicle moves, the position acquisition component 600 can trigger a signal and send it to the processing component 500. The processing component 500 receives the signal of the position acquisition component 600 and controls the image acquisition component 400 to trigger shooting and start image acquisition. That is to say, when the movable vehicle is stationary, that is, not in working state, the image acquisition component 400 is in sleep state, which can reduce energy consumption.

[0055] The position acquisition component 600 is a mileage encoder, which is set on any wheel 130 at the bottom of the movable vehicle. It can form a pulse signal according to the travel distance of the wheel 130 and output it to the processing component 500. In conjunction with it, the processing component 500 can calculate the position and speed of the movable vehicle through the number and frequency of pulses.

[0056] The processing component 500 is a microcomputer used for image storage, transmission and processing. The microcomputer is equipped with a memory card, a processor,

[0057] The processing component 500 is connected to the image acquisition module 400 and the mileage acquisition module 600 respectively. The storage card is used to store the image data acquired by the image acquisition module 400 and the position data acquired by the mileage acquisition module 600. The processor matches the image data and the position data to combine the image data with the position data, thereby ensuring that the acquired image has accurate position information and identifying the image.

[0058] The above-mentioned processor uses a built-in deep learning algorithm to automatically identify defects and diseases of track beams based on the deep learning algorithm.

[0059] Through the cooperation of the image acquisition module 400 and the mileage acquisition module 600, the position information of the movable vehicle at the current moment can be determined based on the signal of the mileage acquisition module 600, and the position information of the movable vehicle at each moment can be recorded. The staff can retrieve the movement record of the movable vehicle to trace back the operation process of the track inspection vehicle, and when the processor recognizes that the track beam in the image has defects or diseases, the staff can obtain the location of the defects or diseases on the track beam in the first time because the image information carries the position information, so as to facilitate timely maintenance.

[0060] The following examples illustrate the working process of the present invention in a specific application. It should be noted that the following content is only a specific application example of the present solution and does not constitute a limitation to the present solution.

[0061] (1) Place the movable trolley on the track beam, adjust the directions of the lenses of the three CMOS cameras so that the first CMOS camera 4101 is aimed at the front of the track beam, the second CMOS camera 420 and the third CMOS camera 430 are aimed at the two sides of the track beam respectively, and adjust the first LED light 310 and the second LED light 320 so that the light source lights illuminate the surface of the track beam that the camera needs to collect.

[0062] (2) The movable vehicle is started and moves forward. The position acquisition component 600 sends a pulse signal. The processing component 500 receives the signal from the position acquisition component 600 and controls the three CMOS cameras to trigger shooting, thereby starting image acquisition.

[0063] (3) The processing component 500 receives and stores the images collected by the three COMS cameras and the data of the position acquisition component 600 in real time, corresponds the position of the position acquisition component 600 to the collected image, and automatically identifies the disease in the collected image.

[0064] (4) The trolley continues to move forward until the track beam inspection operation is completed.
