[0049] [Example]

[0050] like Figure 1 As shown, a train running appearance fault collection device includes a housing 1, a camera 2 and a reflector 3;

[0051] The housing 1 includes a movable cover 11, on which a movable door 12 is disposed, and a notch having the same size as that of the movable door 12 is formed on the movable cover 11;

[0052] The camera 2 and the reflector 3 are arranged inside the housing 1. The camera 2 is horizontally placed at the bottom of the housing 1. The reflector 3 is located at the front end of the camera and corresponds to the camera lenses in pairs.

[0053] The position of the camera 2 corresponds vertically to the position of the notch, and an angle greater than 90 degrees is provided between the reflector 3 and the camera 2 .

[0054] The train operation appearance fault collection device can be applied to running vehicles, such as rail trains (including EMUs, trucks, passenger cars, subways or urban railways, etc.), as well as trackless trains and other vehicles that need to run long distances, and even some unmanned vehicles. The vehicle operation fault detection system can detect fault conditions on vehicles in operation, so as to realize non-contact detection of vehicles when the vehicles do not stop or enter the station;

[0055] At the same time, this solution adopts a horizontal arrangement of the camera, and a reflector is set at the front end of the camera. The light band in the camera can be projected to the area to be detected on the train through the refraction of the reflector. At the same time, an angle greater than 90 degrees is set between the reflector and the camera, which can greatly reduce the overall height of the equipment while ensuring the camera's acquisition clarity. Therefore, the device as a whole is not restricted by the on-site conditions of the track bed. At the same time, it greatly shortens the equipment installation period, reduces the cost of the entire set of equipment, and is conducive to the later maintenance and overhaul of the equipment. At the same time, a box with a movable door is set, and the reflector and camera are placed in the box. This can ensure that the train can perform safe and effective acquisition work when it is in operation, and can also protect the cleanliness of the camera lens, thereby ensuring the clarity of the image.

[0056] Furthermore, the included angle between the reflector 3 and the camera 2 is 135 degrees.

[0057] After analyzing the refraction between the reflector and the camera, the inventors found that when the angle between the reflector and the camera is 135 degrees, the camera can capture the train inspection area more clearly and comprehensively through the refraction of the reflector.

[0058] Furthermore, the camera 2 includes a structured light light source for generating structured light projected onto the reflector 3. The outgoing light of the structured light source forms an illumination area, and the illumination area is projected onto the reflector 3. The illumination area is projected onto the vehicle to be collected through refraction of the reflector 3 to cover the area to be detected on the vehicle to be collected.

[0059] Furthermore, the camera 2 also includes an image data acquisition device for acquiring vehicle image information of the area to be detected; the image data acquisition device is used to acquire information on whether the irradiated area on the vehicle fully / partially covers the area to be detected.

[0060] Further, the structured light source is a line light source;

[0061] The outgoing light of the line light source forms an illumination plane, and the illumination plane forms a light band on the reflector 3, and the reflector 3 refracts the light band onto the vehicle to be collected;

[0062] The optical axis of the camera 2 is located in the illumination plane and is used to collect vehicle image information in the area to be detected.

[0063] Furthermore, the movable cover 11 also includes an electric push rod 13, a connecting plate and a sliding mechanism;

[0064] The movable door 12 is provided with a connecting plate, and the length of the connecting plate is equal to the length of the movable door 12;

[0065] Both ends of the connecting plate are connected to a sliding mechanism respectively, and the sliding mechanism is arranged on the movable cover 11;

[0066] One end of the electric push rod 13 is connected to the movable cover 11, and the other end is connected to the connecting plate;

[0067] The sliding mechanism can make the movable door slide along the extension and retraction direction of the electric push rod 13. When the movable door 12 is closed, the movable door 12 is embedded in the notch.

[0068] Further, the sliding mechanism includes a limit switch bracket 132 and a movable door guide rail 131;

[0069] The movable door guide rail 131 is arranged at the bottom of the movable machine cover 11 and is bolted to the movable machine cover 11. The limit switch brackets 132 are arranged at both ends of the movable door guide rail 131.

[0070] The movable door guide rail 131 includes a first guide rail and a second guide rail extending along the extension direction of the electric push rod 13 respectively;

[0071] A slide rail assembly 133 is movably connected to the first guide rail and the second guide rail respectively, and the slide rail assembly 133 is bolted to the movable door 12 .

[0072] Furthermore, a downwardly inclined arc is provided at one end of the movable door guide rail 131 away from the sliding mechanism.

[0073] Furthermore, a folded edge is provided at the edge of the notch, and a sealing strip is pasted on the folded edge.

[0074] The present invention also provides a train running appearance fault collection system, comprising a train running appearance fault collection device, two sensing modules, a server and a terminal device;

[0075] A sensing module is respectively arranged at the front and rear of the collection device, and the first sensing module is used to sense whether the train reaches a preset distance. If the train reaches the preset distance, the first sensing module sends a start control signal to the server;

[0076] The second sensing module is used to sense whether the train has passed through. If the train has passed through, the second sensing module sends a closing control signal to the server;

[0077] The server is used to start or close the movable cover and the camera of the acquisition device after receiving the control signal sent by the first sensing module or the second sensing module. When the camera is started, it collects images of the train through refraction of the reflector;

[0078] The terminal device is used to display the image data collected by the server.

[0079] Compared with the existing technology, the entire detection process can be carried out during the operation of the train, and the real-time acquisition is the appearance image information of the vehicle, so that when the vehicle is subsequently fault-checked, the abnormal parts of the vehicle can be detected in real time and accurately. At the same time, the system also reduces the time of manual re-inspection and improves the detection efficiency.

[0080] The first sensing module includes a speed measuring module, which may include: a speed measuring radar and / or a speed measuring magnet, as well as other speed measuring methods commonly used in the art;

[0081] like Figure 4 As shown, the speed measuring device may include: a start-up magnet A1 and a closing magnet A2, and the start-up magnet A1 and the closing magnet A2 are located on one side of the bottom box along the extension direction of the track, and are used to obtain vehicle information coming from the direction of the start-up magnet A1 and the closing magnet A2.

[0082] The first sensing module also includes an AEI antenna, an AEI host and a vehicle number recognition subsystem; when the train arrives, the wheels pass over the power-on magnet A1 to generate a trigger signal, the vehicle number recognition subsystem enters the vehicle receiving state, starts the AEI antenna to read the vehicle's electronic tag signal, and uploads it to the AEI host for analysis to obtain the vehicle number information; when the wheels pass over the switch door magnet A2, the axle counting and speed measurement are completed, and finally the tag data is combined to complete the tag positioning.

[0083] The working principle of the present invention is:

[0084] S1: A first sensing module is set 30 meters in front of the collection device. The first sensing module is used to sense whether the train has reached a preset distance. If the train reaches the preset distance, the first sensing module sends a start control signal to the server. At the same time, the first sensing module collects vehicle information such as the train number and speed and sends it to the server;

[0085] S2: After receiving the start control signal sent by the first sensing module, the server opens the movable cover of the acquisition device and starts the camera. The camera acquires images of the train through refraction of the reflector. The server stores the data acquired by the camera in correspondence with the vehicle information sent by the first sensing module.

[0086] S3: A second sensing module is then set 30 meters behind the collection device. The second sensing module is used to sense whether the train has passed. If the train has passed, the server will close the camera in the collection device and the movable cover of the collection device;

[0087] S4: After the acquisition device is turned off, the server sends the acquired image data and the vehicle information corresponding to the image data to the terminal device, and the terminal device is used to display the image data acquired by the server and the vehicle information corresponding to the image data.
