Description

Technical Field

[0001] This application relates to the field of machine vision, and more particularly to a linear array scanning imaging device for receiving and dispatching trains. Background Technology

[0002] During train operation, stations must, in accordance with the train timetable and relevant regulations, handle operations such as route planning, signal opening, train reception guidance, car coupling and uncoupling, and train-machine handover for departing and arriving trains. Upon receiving a train, station staff must organize personnel to inspect the train operation equipment to ensure it is in normal working order. They must also inspect the train and verify car numbers and numbers before the handover can proceed. Currently, manual train reception and inspection are commonly used. Before departure, a technical inspection of the train must be conducted to ensure that the rolling stock and equipment are in good working order.

[0003] In the current train arrival and departure procedures, railway train arrival and departure operations primarily rely on assistant duty officers using the traditional "three-sided, six-look" method to identify and prevent potential safety hazards during train departure and operation, ensuring vehicle safety. This model heavily depends on manual judgment, leading to a continuous occurrence of safety risks. Furthermore, manual inspection is not only time-consuming and labor-intensive, but also presents significant challenges in data retention, as some inspection items can only be recorded manually, further hindering the improvement of safety management levels.

[0035] Specific references Figures 1 to 5 As shown, as a specific embodiment of a linear array scanning imaging device for receiving and dispatching trains according to this application, it includes: a base 5, a linear array light source 1, a linear array camera 3, a lens 31, a drive circuit board 2, and an aviation plug 4.

[0036] The base 5 is a cuboid; a first box 51, a second box 52 and a third box 53 are provided on the outer surface of the base 5; the first box 51 is located in the center of the base 5; the second box 52 and the third box 53 are symmetrically arranged on both sides of the first box 51; a first window 7 is provided on the side of the first box 51; a second window 8 is provided on the top of the second box 52 and the third box 53.

[0037] The linear array light source 1 is set inside the second box 52 and the third box 53, and can emit light from the second window 8 to the surface of the object to be measured to generate reflected light;

[0038] The line scan camera 3 is installed inside the first housing 51; the lens 31 is installed on the front side of the line scan camera 3 and is correspondingly set with the first window 7, enabling the line scan camera 3 to collect reflected light.

[0039] like Figure 1 As shown, this utility model discloses the structure of the device, wherein the base 5 serves as the mounting foundation, providing a stable bearing platform for other components, ensuring that the positions of each component are relatively fixed during operation, and that the overall performance of the device is not affected by shaking or displacement, thus guaranteeing the accuracy and stability of image acquisition.

[0040] This invention distributes the linear array light source 1 on both sides of the camera, providing uniform illumination to the sides of the train. Uniform illumination eliminates shadows and reflections caused by uneven lighting, making the images captured by the linear array camera 3 clearer and enabling more accurate identification of information about the sides of the train.

[0041] The line array camera 3 is used to acquire images of the train's side. This invention places the line array camera 3 in the center of the base 5, ensuring a more balanced position for the camera within the device. This allows for more even reception of light from the train's side when acquiring images, reducing uneven image acquisition caused by positional shifts and improving image quality. The well-designed placement of the lens 31 in front of the line array camera 3 accurately focuses the light reflected from the train's side onto the camera's sensor, ensuring clear and accurate acquisition of image information from the train's side, providing reliable data for subsequent safety inspections.

[0042] In one possible implementation, the linear array light source 1 includes a plurality of LED light groups 11; the plurality of LED light groups 11 are connected in series or in parallel.

[0045] This utility model discloses the arrangement of the linear array light source 1 and the linear array camera 3, as well as the structure of the linear array light source 1. The linear array light source 1 consists of several LED light groups 11 connected in series, and each LED light group 11 is composed of several LED lights 111 connected in series. This linear array light source 1, with its LED light groups 111 and LED lights 111 arranged in a linear series configuration, can project the light emitted by the LED lights 111 onto the surface of the train being tested through optical path shaping, forming a relatively uniform linear light band that matches the scanning characteristics of the linear array camera 3. This layout allows for more uniform illumination of the train's side, reducing blind spots and further improving the uniformity and accuracy of image acquisition, better meeting the needs of train arrival and departure inspection. Preferably, the linear array camera 3 and lens 31 are mounted on the base 5 using screws 54.

[0046] In one possible implementation, the second box 52 and the third box 53 are the same size.

[0047] In one possible implementation, the lengths of the first box 51, the second box 52, and the third box 53 are the same as the width of the base 5.

[0048] In one possible implementation, the sum of the widths of the first box 51, the second box 52, and the third box 53 is equal to the length of the base 5.

[0049] The first housing 51 disclosed in this utility model provides a space for housing and protecting the LED light assembly 11, preventing damage to the light assembly from external factors such as dust, rain, and collisions, and extending the service life of the light assembly. The design of the first window 7 ensures that the light can be emitted smoothly, provides a certain degree of protection for the light assembly, and can also regulate the direction of light emission, thereby improving lighting efficiency.

[0050] The second housing 52 disclosed in this utility model provides a good environment for housing and protecting the line scan camera 3 and lens 31, preventing external dust, debris, etc. from entering the housing and avoiding contamination and damage to the camera and lens 31, thus ensuring the stability of their optical performance. The design of the second window 8 ensures that the lens 31 can normally collect external light, while also providing a certain degree of protection for the camera and lens 31.

[0051] In one possible implementation, it also includes a drive circuit board 2 and an aviation connector 4;

[0052] The drive circuit board 2 is mounted on the base 5; the drive circuit board 2 is electrically connected to the line scan camera 3, the line scan light source 1, the lens 31 and the aviation plug 4;

[0053] The aircraft plug 4 is disposed on the outer surface of the first housing 51; the aircraft plug 4 is connected to an external power supply.

[0054] The connector 4 is positioned on the outer surface of the second housing 52, facilitating connection and disconnection with an external power source and improving the installation and maintenance efficiency of the device. Preferably, in this invention, the connector 4 is mounted on the outer surface of the second housing 52 using screws.

[0055] The drive circuit board 2 disclosed in this utility model is the electrical control core of the device. Through electrical connection with various components, it can realize the power supply and signal control of components such as the line scan camera 3 and the line scan light source 1. It can coordinate the working timing and parameter settings of various components to ensure the overall coordinated operation of the device and efficiently complete the image acquisition task.

[0056] This utility model discloses a method of connecting the drive circuit board 2 and an external power supply using an aviation connector 4, which is convenient, quick, and provides a stable connection. The aviation connector 4 has good contact performance and a high protection level, effectively preventing the generation of electrical sparks during connection and disconnection, preventing safety issues such as short circuits, and preventing dust and moisture from entering the device, thus ensuring the electrical safety and service life of the device. Preferably, the drive circuit board 2 is mounted on the base 5 using screws 54.

[0057] It is worth noting that in the technical solution disclosed in this utility model, the drive circuit board 2 has two feasible implementation forms. First, the drive circuit board 2 can be a separate drive circuit board 2, directly covering the surface of the base 5, and electrically connected and mechanically fixed to the base 5 and other related components through a specific connection method; second, as... Figure 1 As shown, the drive circuit board 2 can also be a component of the base 5 itself, that is, as a specific area or functional module on the base 5, integrated with other structures to form a complete device structure.

[0058] In one possible implementation, the lens 31 extends through the first window 7 to the outside of the second housing 52.

[0059] In one possible implementation, a fixing structure 6 is provided on the base 5.

[0060] When used in the field, users only need to connect the device to the field machinery by installing the fixing structure 6, and provide overall power supply and signal triggering.

[0061] During use, external power and signals are transmitted to the drive circuit board 2 inside the device through the power supply connector 4. Upon receiving the external signals and power, the drive circuit board 2 transmits the power and signals to the line array light source 1, the line array camera 3, and the lens 31 via wires, thereby enabling light emission from the light source and data acquisition by the line array camera 3. When the line array camera 3 and lens 31 receive the power and converted circuit signals from the drive circuit board 2, they begin data acquisition. The light emitted by the line array light source 1 is reflected from the surface of the object being measured and then enters the line array camera 3 and camera lens 31.
