Description

Technical Field

[0001] This invention relates to the field of vehicle inspection technology, specifically a comprehensive inspection system and method for train exteriors. Background Technology

[0002] Train safety relies on thorough daily maintenance to ensure its reliability. This is because routine maintenance allows for the timely detection and resolution of potential safety hazards, ensuring the train remains in good technical condition throughout operation. Many train components gradually lose performance over time due to wear, aging, or fatigue. Regular maintenance checks of these components can identify potential problems early, such as wear on the braking system, aging electrical wiring, and cracks in the wheels. For example, cracks or excessive wear on the wheel treads can increase vibrations during train operation, potentially leading to derailment. Timely replacement or repair of wheels during routine maintenance can effectively prevent this risk. Many major accidents are often triggered by seemingly insignificant problems. For instance, a loose bolt, a leaky valve, or a faulty electrical connection can trigger a chain reaction during train operation, ultimately leading to a serious accident. Routine maintenance allows for the timely handling of these minor issues, preventing them from escalating into uncontrollable major malfunctions.

[0003] Currently, routine train maintenance is typically performed manually. After a train returns to its designated track, maintenance personnel inspect the running gear and undercarriage electrical equipment, meticulously examining every component visually, down to the smallest bolt. While manual labor ensures thorough inspection, it also suffers from drawbacks such as high labor intensity, low efficiency, significant susceptibility to human error, difficulty in achieving comprehensive coverage, challenges in data recording and traceability, high costs, and inability to handle large-scale maintenance demands. These issues negatively impact the quality and efficiency of train maintenance, consequently affecting the safe operation of trains and the overall efficiency of railway transportation.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] Example: Figure 1 and Figure 2 As shown, a comprehensive train exterior inspection system mainly consists of exterior inspection equipment, an online inspection information management platform, and a maintenance business platform. The information collected by the exterior inspection equipment includes train number, train speed, undercarriage and side exterior appearance, pantograph, wheelset dimensions and tread scratch condition, and temperature data. The exterior inspection equipment includes a 360° dynamic image intelligent inspection device, an undercarriage inspection robot, an online pantograph inspection device, a wheelset dimension and tread fault detection device, a wheelset flaw detection online monitoring device, and axle temperature and motor temperature detection devices. The 360° dynamic image intelligent inspection device performs all-around dynamic image inspection of the train exterior; the undercarriage inspection robot inspects the undercarriage; the online pantograph inspection device monitors the pantograph's status in real time; the wheelset dimension and tread fault detection device detects wheelet dimensions and tread faults; and the online wheelset flaw detection device... The wheelset undergoes online flaw detection, and the aforementioned axle temperature and motor temperature detection devices can monitor the axle temperature and motor temperature. The aforementioned online inspection information management platform includes an integrated acquisition interface module, a data management center, a data cleaning module, a data edge analysis module, and a data integration and display module. Through the aforementioned integrated acquisition interface module, the aforementioned data management center, the aforementioned data cleaning module, the aforementioned data edge analysis module, and the aforementioned data integration and display module, the data obtained by the aforementioned appearance inspection equipment is integrated, cleaned, analyzed, and displayed, and the analyzed data is transmitted to the aforementioned maintenance business platform, which is used to manage maintenance business.

[0030] The data obtained by the aforementioned appearance inspection equipment is transmitted to the aforementioned trackside server via fiber optic or wireless network. The trackside server then transmits the data to the data center via fiber optic, and the data center then transmits the data to the trackside intelligent inspection and management system. By comparing the pre-stored data in the trackside intelligent inspection and management system with the newly obtained data, the inspection results are linked to the aforementioned maintenance business platform. In other words, the train appearance comprehensive inspection system mainly consists of a front-end acquisition module and a back-end control and maintenance unit. When the system detects that a train is about to enter, the system starts working, using the front-end acquisition module to acquire 360° high-definition images of the train's front, car number, body, and rear. After acquisition, the front-end acquisition module transmits the acquired data to the host control system via the trackside server (i.e., the trackside car number acquisition device) and the trackside control system. Then, using wireless communication, the data is connected to the intelligent operation and maintenance platform, enabling remote real-time operation and maintenance by back-end personnel.

[0031] The train appearance comprehensive inspection system also includes an alarm module. When the comparison results between the pre-stored data in the above-mentioned trackside intelligent inspection and management system and the newly acquired data are different, the alarm module will issue an alarm to promptly notify the maintenance personnel to carry out maintenance operations on the train and ensure its normal operation.

[0032] Specifically, the appearance inspection equipment in this embodiment includes an inspection box 2 that can be erected above the track 1. Both ends of the inspection box 2 are open to allow trains 3 to pass through. A roof image detection module 4 is installed on the top inner part of the inspection box 2, and a side image acquisition module 5 is installed on the side of the inspection box 2. A vehicle number recognition module 6 and a train arrival speed measurement module 7 are also installed at the openings of the inspection box 2. To achieve comprehensive inspection, multiple roof image detection modules 4 are used, and these modules are equidistantly arranged along the width of the inspection box 2. To ensure the accuracy of the speed measurement results, two train arrival speed measurement modules 7 are used: one is installed on the track 1, and the other is located at the exit of the inspection box 2.

[0033] As an important part of the intelligent operation and maintenance of rail transit vehicles, the 360° dynamic image intelligent inspection device, used in conjunction with the train undercarriage robot, forms a complete train inspection solution, improves the inspection items, and enhances the inspection quality. Specifically, the defects identified by the undercarriage inspection robot include whether bolts are loose, whether pins are loose, whether pipelines are messy, whether nameplates are detached, whether exhaust vents are unobstructed, whether keyhole covers are misaligned, whether cable ties are loose, whether temperature labels are misaligned, whether oil levels meet requirements, and whether valves are misaligned.

[0034] A comprehensive train exterior inspection system also includes a side defect identification device. This device detects defects including those in the bogie, suspension, train wheels, and other side surfaces. The side defect identification device can perform a comprehensive inspection of the train's sides, ensuring that the appearance and structural integrity of all parts of the train are fully checked. Furthermore, by detecting defects in critical components such as the bogie, suspension, and wheels, it can prevent train accidents caused by component failures, ensuring safe train operation. Timely detection of side defects can reduce maintenance costs due to component damage and avoid train downtime and repair expenses caused by malfunctions.

[0035] This embodiment of a comprehensive train appearance inspection system involves setting up appearance inspection equipment, an online inspection information management platform, and a maintenance business platform, and linking these three components together. Specifically, data detected by the appearance inspection equipment is uploaded to the online inspection information management platform in real time. The system also analyzes and compares the data detected by the appearance inspection equipment with the existing data on the online inspection information management platform, and transmits the comparison results to the maintenance business platform. This automated inspection equipment can quickly complete the inspection of the train's appearance. Compared to traditional manual inspection methods, this significantly shortens inspection time, improves inspection efficiency, and enhances the user experience, thus facilitating the promotion and application of this comprehensive train appearance inspection system in the field of vehicle inspection technology.

[0036] The appearance inspection equipment in this embodiment includes a 360° dynamic image intelligent inspection device, a vehicle undercarriage inspection robot, an online pantograph inspection device, a wheelset size and tread fault detection device, an online wheelset flaw detection monitoring device, and an axle temperature and motor temperature detection device. Compared with manual inspection, the above devices can more accurately identify defects and damages on the train's appearance, reducing misjudgments and omissions caused by human factors.
