Description

Technical Field

[0001] This utility model relates to the field of railway vehicle information management, and in particular to the hardware structure of a railway vehicle information identification system. Background Technology

[0002] Traditional railway vehicle information management relies on manual data entry. Inspectors must manually transcribe, verify, and compile vehicle information under various weather conditions, and then re-enter the compiled vehicle information into the software system. This process suffers from high labor intensity, poor working environment, low safety, and low work efficiency. Therefore, it is necessary to study the hardware structure of a railway vehicle information identification system to solve these problems. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing a hardware structure for a railway vehicle information identification system.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a hardware structure for a railway vehicle information identification system, comprising:

[0005] The equipment is mounted on gantry frames, which are installed on both sides of the rails at each lane information detection location.

[0006] The image acquisition module is used to acquire images of train car number and model. It includes a camera, a fill light, and a camera housing installed on the inner left and right sides of the equipment mounting gantry. The camera is installed inside the camera housing, and the fill light is installed next to the camera via a corresponding bracket.

[0007] The data processing module is used to receive and process image data, including a railway vehicle detection host, an industrial identification host, and a railway vehicle number identification host connected in sequence.

[0008] The network transmission module is used to realize data communication, including a switch, a fiber optic transceiver and a fiber optic box connected in sequence. The switch is connected to the industrial identification host and the camera respectively.

[0009] The wheel detection module is used to detect wheel signals and trigger the image acquisition module to work. It includes two sets of sensors, which are installed on one side of the rail and located on the front and rear sides of the equipment mounting gantry. The sensors are connected to the railway vehicle detection host.

[0010] In particular, the equipment mounting gantry is inverted U-shaped, and has bases on both sides at the bottom.

[0011] Specifically, the camera system is configured in two groups. Each group consists of two line scan cameras and one area scan camera. The line scan cameras are installed on the upper inner side of the equipment mounting gantry, while the area scan cameras are installed on the lower inner side of the equipment mounting gantry. There are two camera covers, which are respectively installed on the left and right inner sides of the equipment mounting gantry and cover one group of cameras respectively.

[0012] Specifically, there are two sets of supplementary lights. One set of supplementary lights includes two linear array supplementary lights and one area array supplementary light. The linear array supplementary lights and the area array supplementary lights are matched with the corresponding linear array camera and area array camera, respectively.

[0013] Specifically, it also includes a DC12V power supply for powering the camera, an AC220V power supply for powering the area array fill light, and a DC24V power supply for powering the line array fill light.

[0014] Specifically, it also includes RFID antennas and RFID readers. The RFID antennas are symmetrically installed at both ends of the top of the equipment mounting gantry, and the RFID readers are embedded in the middle of the top of the equipment mounting gantry. The RFID antennas are connected to the RFID readers, and the RFID readers are connected to the railway vehicle number identification host.

[0015] The beneficial effects of this utility model are:

[0016] 1. High-precision all-weather identification: RFID + visual dual verification: RFID reads the electronic tag (vehicle ID), and the camera captures the vehicle image. Dual verification ensures the accuracy of identification and is not affected by environmental conditions such as rain, snow, and strong light. At the same time, the supplementary lights are set in stages. The linear array supplementary lights are adapted to high-speed scanning, and the area array supplementary lights provide global illumination to ensure the imaging quality at different vehicle speeds.

[0017] 2. The equipment installation gantry integrates RFID antennas, cameras, and supplementary lighting, reducing the number of devices along the track and improving installation efficiency. Modular power supply for the cameras and supplementary lighting avoids interference and facilitates easier fault isolation. Camera housings protect the cameras, and the RFID reader / writer is embedded inside the installation gantry, providing dust and water resistance and extending equipment lifespan. Sensors are grouped for detection (3 at the front and 3 at the back), with redundancy preventing missed triggers.

[0018] 3. Compared with the traditional manual data entry method, the accuracy of recognition of this utility model is greatly improved. Through the optimization of equipment deployment, the anti-interference ability and recognition ability of the system under various weather conditions are improved. The system does not require the cooperation or assistance of others during operation, which greatly improves work efficiency. Attached Figure Description

Two camera housings 5 ​​are provided, one on the inner side of the equipment mounting gantry 1 and one covering each set of cameras 3. Two sets of supplementary lights 4 are also configured, each set including two line-array supplementary lights and one area-array supplementary light, matched to the corresponding line-array and area-array cameras. The module also includes a DC 12V power supply for powering the cameras 3, an AC 220V power supply for powering the area-array supplementary lights, and a DC 24V power supply for powering the line-array supplementary lights.

[0028] The data processing module is used to receive and process image data, including a railway vehicle detection host 6, an industrial identification host 7, and a railway vehicle number identification host 8 connected in sequence; the network transmission module is used to realize data communication, including a switch 9, a fiber optic transceiver 10, and a fiber optic box 11 connected in sequence. The switch 9 is connected to the industrial identification host 7 and the camera 3 respectively; the switch 9 transmits data remotely through the fiber optic transceiver 10 to adapt to the complex electromagnetic environment of the railway.

[0029] The wheel detection module, used to detect wheel signals and trigger the image acquisition module, includes two sets of sensors 12, installed on one side of the rail 2 and located on the front and rear sides of the equipment mounting gantry 1. The sensors 12 are connected to the railway vehicle detection host 6. The sensors 12 are grouped for detection (3 at the front and 3 at the rear), and the redundant design avoids missed triggers.

[0030] It also includes an RFID antenna and an RFID reader / writer. The RFID antenna is symmetrically installed at both ends of the top of the equipment mounting gantry 1. The RFID reader / writer is embedded in the middle of the top of the equipment mounting gantry 1. The RFID antenna is connected to the RFID reader / writer, and the RFID reader / writer is connected to the railway vehicle number identification host 8.

[0031] High-precision all-weather identification: RFID + visual dual verification: RFID reads the electronic tag (vehicle ID), camera 3 captures vehicle images, and dual verification ensures identification accuracy, unaffected by rain, snow, strong light and other environmental conditions. At the same time, the supplementary light 4 is set in stages, with linear supplementary light adapted to high-speed scanning and area supplementary light providing global illumination to ensure imaging quality at different vehicle speeds.

[0032] The equipment installation gantry 1 integrates an RFID antenna, camera 3, and supplementary light 4, reducing the number of devices along the track and improving installation efficiency.

[0034] Working principle:

[0035] 1. Triggering stage: Wheel detection. When a train passes by, the sensors 12 (3 in each group) on both sides of the rail 2 detect the wheel signal, triggering the railway vehicle detection host 6 to start the system.

[0036] 2. Data Acquisition Phase:

[0037] RFID identification: The RFID antenna on top of the mounting gantry 1 transmits radio frequency signals to read the electronic tags on the roof / side boxes of the vehicle. The RFID reader decodes the tag data (vehicle ID) and uploads it to the railway vehicle number identification host 8.

[0038] Image acquisition: Linear scan cameras scan the sides of the vehicle, working in conjunction with linear scan fill lights (high-frequency flash) to capture details of high-speed movement. Area scan cameras capture a global image of the underside of the vehicle, working in conjunction with area scan fill lights (constantly on) to provide uniform illumination.

[0039] 3. Data Processing Stage: Data fusion. The railway car number identification host 8 compares the RFID car number with the image recognition results, aligns them spatiotemporally (error ≤ 50ms), and outputs the final car number. The industrial identification host 7 analyzes features such as car type (open wagon, flatcar, covered wagon, etc.) and number of wheels.

[0040] 4. Data transmission stage: All data is aggregated through switch 9 and transmitted to the server in the computer room via fiber optic transceiver 10, and then associated with the production system to complete business logic such as vehicle number entry and empty / loaded vehicle verification.

[0041] The accuracy of identification is greatly improved by this invention. Through optimization of equipment deployment, the system’s anti-interference ability and identification ability under various weather conditions are improved. The system does not require the cooperation or assistance of others during operation, which greatly improves work efficiency.
