Description

Technical Field

[0001] This utility model relates to the technical field of railway intelligent monitoring equipment, specifically to a train leader for railway shunting operations. Background Technology

[0002] In railway shunting operations, traditional methods rely on shunting operators to cling to the front of the vehicle for observation, which poses a high risk of falling and collision. To address this, the industry has begun developing a lead vehicle device in recent years to replace manual clinging.

[0003] Currently, some vehicle guidance devices have adopted a technical approach that combines video capture with radar detection. These devices use a camera and radar sensor mounted on the front of the vehicle. The camera captures video images, while the radar simultaneously emits electromagnetic waves and receives reflected signals to detect the distance to obstacles ahead.

[0004] However, the existing technical approach of "video acquisition combined with radar detection" has the following drawbacks:

[0005] 1. High false alarm rate of radar: A large number of metal components such as rails, sleepers, signals, and wheelsets along the railway line continuously reflect radar waves, making it impossible for the radar to distinguish between fixed equipment and dangerous obstacles, resulting in frequent false alarms; lowering the sensitivity makes it easy to miss small foreign objects, creating a safety blind spot.

[0006] 2. Complex system with high failure rate: The radar and camera are two heterogeneous sensors that need to be powered independently and registered synchronously, resulting in a large number of hardware components and connectors; the radar radio frequency module is easily damaged under long-term vibration and shock of the vehicle, resulting in poor overall reliability.

[0007] 3. High power consumption, bulky and difficult to operate: The radar radio frequency transmission unit has continuous high power consumption, and a large-capacity battery is required to meet the 8-hour battery life, resulting in a heavy equipment weight; the labor intensity is high when shunting personnel frequently disassemble and assemble, and the equipment is prone to falling.

[0008] 4. High procurement and maintenance costs: Industrial-grade radar modules have high unit prices, and the total cost of deploying multiple devices in batches is high, which is not conducive to the promotion of the entire line.

[0009] Therefore, there is an urgent need for a highly reliable, lightweight, low-power, and low-cost railway shunting vehicle leader. Utility Model Content

[0010] This invention aims to overcome the personal safety risks of manual boarding and lookout, as well as the shortcomings of existing "video + radar" train shunting devices, such as high false alarm rate, system complexity, high power consumption, bulky equipment, and high cost; and provides a lightweight railway shunting train shunting device that integrates pure visual perception, Beidou RTK high-precision positioning, and end-side local intelligent analysis.

[0011] To alleviate or partially alleviate the above-mentioned technical problems, the solution of this utility model is as follows:

[0012] On the one hand, this utility model provides a train shunting guide device, comprising:

[0013] shell;

[0014] A video acquisition module, comprising a telephoto camera and a wide-angle camera;

[0015] The optical axis of the telephoto camera lens is parallel to the horizontal plane, and the optical axis of the wide-angle camera lens is deflected by a preset angle relative to the horizontal plane towards the lower end of the housing.

[0016] An intelligent analysis and processing module is connected to the video acquisition module via a signal connection.

[0017] In one possible implementation of this utility model, the housing includes a front and a back, and both the telephoto camera and the wide-angle camera are disposed on the front of the housing.

[0018] In one possible implementation of this utility model, the preset angle is 20° to 40°.

[0019] In one possible implementation of this utility model, the vehicle guide further includes a positioning module, which is used to acquire the location information of the vehicle guide in real time.

[0020] In one possible implementation of this utility model, the positioning module is a BeiDou system RTK high-precision positioning module.

[0021] In one possible implementation of this utility model, the vehicle guide further includes a communication module, which is signal-connected to the video acquisition module and the positioning module respectively.

[0022] In one possible implementation of this utility model, the communication module is a 5G / 4G cellular communication unit.

[0023] In one possible implementation of this utility model, the vehicle guide further includes a main circuit board, on which the intelligent analysis and processing module, the positioning module, and the communication module are all integrated.

[0024] In one possible implementation of this utility model, the vehicle guide further includes a heat dissipation grille, which is disposed on the upper end of the housing.

[0025] In one possible implementation of this utility model, the vehicle guide further includes a magnetic fixing unit, which is disposed on the back of the housing.

[0026] The present invention has some or all of the following beneficial technical effects:

[0027] (1) This utility model completely abandons the radar radio frequency module and relies on the dual-channel dedicated camera video acquisition module combined with the end-side intelligent analysis and processing module for visual recognition to avoid radar false alarms caused by rails and trackside metal components. The accuracy of obstacle recognition is significantly improved, and the hidden danger of safety warning failure is eliminated.

[0028] (2) This utility model integrates the video acquisition module, intelligent analysis and processing module, positioning module and communication module into a main circuit board, reducing the number of cables, independent shielding shells and connectors, adapting to the continuous vibration and impact environment of railway vehicles, and greatly reducing the equipment failure rate.

[0029] (3) This utility model uses only passive camera devices to eliminate the power consumption of continuous radar transmission; the battery capacity required for the same 8-hour battery life is smaller, and the weight of the whole machine is greatly reduced; the high-priced radar module is eliminated, the core components are integrated in a unified manner, the procurement and maintenance costs of a single device are reduced, and it is suitable for large-scale deployment on multiple shunting lines and multiple shunting locomotives.

[0030] (4) This utility model can simultaneously complete long-distance signal observation, detection of foreign objects or derailers near the rail surface, and fully meet the observation requirements of shunting and propulsion operations; with Beidou RTK centimeter positioning, ground dispatch can simultaneously grasp the precise position of the train and the road conditions ahead.

[0031] (5) This utility model can independently complete obstacle identification and sound and light warning in tunnels and mountainous areas with weak 5G coverage by using local intelligent analysis and reasoning on the end side. The safety of operation is not limited by communication signals.

[0032] Furthermore, other beneficial effects of this invention will be mentioned in the specific embodiments. Attached Figure Description

Figure 2 This is a front view of the back of the vehicle guide device according to one embodiment of this utility model. Figure 3 This is a side view of a vehicle guide device according to another embodiment of the present invention.

[0041] like Figure 1-3 As shown in this embodiment, the present invention provides a train shunting leader, including a housing 1, a video acquisition module, and an intelligent analysis and processing module.

[0042] The video acquisition module adopts a railway-specific dual-view video monitoring subsystem, which includes a telephoto camera 2 and a wide-angle camera 3.

[0043] The telephoto camera 2 is disposed on the front of the housing 1. The optical axis of the lens of the telephoto camera 2 is parallel to the horizontal plane. The telephoto camera 2 is used to collect video images of the status of railway signal displays ahead of the train, the condition of the level crossing, and obstacles on the track at a distance.

[0044] The wide-angle camera 3 is mounted on the front of the housing 1, such as... Figure 1 As shown in the example, the wide-angle camera 3 is positioned below the telephoto camera 2, and the optical axis of the lens of the wide-angle camera 3 is deflected by a preset angle relative to the horizontal plane toward the lower end of the housing 1; the wide-angle camera 3 is used to specifically collect close-up images of the track surface area in the downward direction at the front of the train, covering railway-specific needs such as track surface foreign object detection, derailer status confirmation, and coupler connection status observation.

[0045] Preferably, the wide-angle camera 3 is positioned directly below the telephoto camera 2.

[0046] The intelligent analysis and processing module is connected to the video acquisition module via a signal. The two video streams acquired by the telephoto camera 2 and the wide-angle camera 3 are transmitted to the intelligent analysis and processing module for real-time intelligent analysis, including automatic recognition of the color and status of railway signal lights, real-time detection and classification of foreign objects on the track surface (such as abandoned tools, scattered goods, fallen rocks, etc.), automatic detection and alarm of personnel intruding on the track, and detection and distance estimation of obstacles in front of the train.

[0047] The intelligent analysis and processing module built into the vehicle guide includes an eight-core CPU, an ARM Mali-G68 graphics processor, and an APU 3.0 AI acceleration unit integrated on the motherboard. The APU 3.0 AI acceleration unit has an edge-side AI inference computing power of approximately 4 TOPS (4 trillion operations per second). The intelligent analysis and processing module runs a pre-built lightweight visual AI inference model to perform real-time intelligent analysis of the two video streams locally on the device, without relying on cloud computing power on the network side, ensuring autonomous intelligent operation in areas with weak 5G / 4G signal coverage such as tunnels and mountainous areas.

[0048] In one possible implementation of this utility model, the preset angle is 20° to 40°, preferably 30°; it is specifically used to collect near-ground rail surface images within a range of 0 to 15 meters from the front rail surface of the train, covering the rail surface foreign objects (such as abandoned tools, scattered goods), derailer status, coupler connection status and other railway shunting-specific observation needs.

[0049] In one possible implementation of this utility model, such as Figure 1 As shown, the vehicle guide also includes a positioning module 4, which is used to acquire the location information of the vehicle guide in real time.

[0050] In one possible implementation of this utility model, the positioning module 4 is a Beidou system RTK high-precision positioning module, which achieves centimeter-level positioning accuracy by receiving differential correction signals from ground reference stations.

[0051] In one possible implementation of this utility model, the vehicle guide further includes a communication module, which is signal-connected to the video acquisition module and the positioning module respectively.

[0052] The communication module integrates a 5G / 4G cellular communication unit, which is used to transmit the video images captured by the video acquisition module and the location information obtained by the positioning module back to the ground control terminal in real time.

[0053] In one possible implementation of this utility model, the vehicle guide further includes a main circuit board, on which the intelligent analysis and processing module, the positioning module, and the communication module are all integrated.

[0054] In one possible implementation of this utility model, the vehicle guide further includes a heat dissipation grille, which is disposed on the upper end of the housing.

[0055] In one possible implementation of this utility model, the vehicle guide further includes an operation button, which is located at the lower end of the front of the housing 1. The operation button includes three raised anti-slip buttons.

[0056] In one possible implementation of this utility model, the vehicle guide further includes a supplementary lighting unit, which is disposed on the front of the housing 1 and automatically starts when the ambient illuminance is lower than a preset threshold. The intelligent analysis and processing module has a built-in low-illuminance image enhancement algorithm, which uses the GPU to perform real-time enhancement processing on the close-up image of the track surface under supplementary lighting, so as to ensure the accuracy of AI target detection and classification in low-illuminance environments such as night and tunnels, while ensuring the quality of video acquisition.

[0057] In one possible implementation of this utility model, the car guide further includes a magnetic fixing unit, which is disposed on the back of the housing and is used to detachably fix the car guide to the front coupler, car ladder or special mounting bracket of the railway vehicle.

[0058] In one possible implementation of this utility model, the vehicle guide further includes a power module, which includes a rechargeable lithium battery. The bottom of the outer shell 1 is provided with a quick-release battery compartment cover, which is detachably connected to the outer shell through a buckle structure. A sealing gasket for waterproofing is provided at the buckle joint, so as to ensure the battery compartment is waterproof and sealed while realizing quick battery swapping.

[0059] In one possible implementation of this utility model, the vehicle guide further includes an auxiliary interface, which includes a Type-C charging interface and a USB data interface, and is disposed on the side or back of the housing. The auxiliary interface is covered by the waterproof and dustproof cover.

[0060] In one possible implementation of this utility model, the vehicle guide further includes a status indicator light, which is disposed on the front of the housing 1 and is used to indicate the communication connection status, positioning status, and power status.

[0061] In one possible implementation of this utility model, the communication module further includes a voice communication unit for enabling full-duplex voice communication with the shunting foreman, driver, and other operators.
