Background Art

[0002] As a key mode of freight logistics, railway freight transport plays a vital role in my country's transportation system. Railway freight transport can transport a wide range of goods, including bulk commodities, breakbulk cargo, hazardous materials, fresh food, and express mail. Its transportation services are characterized by all-weather, full-route delivery, large volumes, high speeds, and low costs. However, railway transport safety is fundamental and a crucial guarantee for logistics operations. Only by implementing and improving safety measures can the advantages of railway logistics be fully leveraged. Against this backdrop, the frequent occurrence of overloads and foreign objects has become a major challenge for railway transport safety management. These issues not only slow down freight transport efficiency and increase operating costs, but more importantly, they can lead to serious safety incidents such as cargo damage and train derailments, posing a threat to the safety of people and property.

[0003] While the railway industry has implemented various measures to address these issues, most current solutions still rely on manual inspections and simple mechanical devices. These methods are not only time-consuming and labor-intensive, but also inefficient and difficult to guarantee accuracy. With the ever-increasing volume of rail transport and the increasing demands for transport safety and efficiency, traditional methods are no longer able to meet the demands of modern rail transport. Therefore, the development of an efficient and automated inspection system to address these issues has become an urgent need within the railway industry. Accurate detection of foreign objects and off-center loads in rail freight transport is crucial to transport safety.

[0004] To find the same technical reports through query retrieval, only technical literature in related fields is available, and the closest ones are the following:

[0005] 1. Patent number CN201120212191.X, entitled "Railway Freight Car Onboard Intelligent Monitoring System for Overload and Unbalanced Loading," discloses a railway freight car onboard intelligent monitoring system for overload and unbalanced loads. The system comprises a field data acquisition unit, a wireless communication module, a high-capacity data storage module, a wide-temperature LCD display module, a function key module, and an onboard computer. The overload and unbalanced load detection device includes a microprocessor, an A / D converter, and displacement sensors for measuring the elastic deformation of the secondary springs. The displacement sensors are connected to the microprocessor via the A / D converter, which in turn is connected to a GSM-R wireless module. Four displacement sensors are installed between the bolsters of the front and rear bogies of the railway freight car and the secondary spring support beams. While the patent proposes a method for detecting unbalanced loads in railway freight cars, it relies solely on monitoring with displacement sensors. While this method is relatively accurate, the system is mounted on the vehicle and operates with it, making it susceptible to damage. Furthermore, the system still cannot detect foreign objects in the cargo.

[0006] 2. Patent number CN201110124259.3, named "Real-time Monitoring Method for Overloading and Unbalanced Loading of Railway Freight Cars", discloses a real-time monitoring method for overloading and unbalanced loading of railway freight cars, and proposes characteristics for railway freight safety work. During the loading process of railway freight cars, the cargo weight value of each of the four corners of the car, the total weight value of the cargo and the relevant center of gravity projection point data are displayed in real time with intuitive graphics to facilitate loaders to make timely judgments. The patent proposes an overload monitoring method that involves installing four electronic weighing scales beneath the tracks of a dedicated truck line. The four electronic scales are connected to a computer monitoring system. The track gauge and truck distance values ​​are input into the computer monitoring system. A truck to be loaded is driven onto the dedicated truck line, with the four wheel sets of the truck carriage placed on the electronic weighing scales. The carriage tare weight is first measured and recorded and stored by the computer monitoring system. During the loading process, the four electronic scales display the cargo weight at each corner and the total weight of the cargo in real time. The computer monitoring system calculates the projected center of gravity of the cargo based on the real-time cargo weight at each corner, the track gauge, and the truck distance. The projected center of gravity is then used to determine whether the center of gravity is within a pre-set freight safety range. This monitoring method involves installing four electronic scales beneath the tracks of the dedicated line, sensing the weight through the passage of vehicles. This can easily damage the electronic scales.

[0007] 3. Patent application number CN202011476581.8, entitled "Railway Freight Car Operation Status Monitoring System," discloses a railway freight car operation status monitoring system, comprising: a status detection module, disposed at each monitoring point of the vehicle, for collecting vehicle status data and performing edge computing on the status data to obtain first analysis data; an on-board gateway, for obtaining the first analysis data when the vehicle is in an operating range, performing fog computing on the first analysis data to obtain second analysis data, and uploading the second analysis data to a server; an on-site gateway, for obtaining the first analysis data when the vehicle is in a non-operating range, performing fog computing on the first analysis data to obtain third analysis data, and uploading the third analysis data to a server; the server is configured to send the second analysis data or the third analysis data to a monitoring center; and the monitoring center is configured to issue an alarm when determining that the vehicle status is abnormal or faulty. This patent only proposes monitoring the overall operation of railway freight cars, but cannot detect overloading of the carriages or identify foreign objects.

[0008] Through careful analysis of the above patents, although these patents all involve monitoring the uneven loading of trucks and also propose improvements to some technical problems, the monitoring technical solutions proposed by these patent technologies are relatively complex, especially they do not propose methods and devices for identifying foreign objects. Therefore, the problems mentioned above still exist, so it is very necessary to improve them. Utility Model Content
