Description

Technical Field

[0001] The present invention belongs to the technical field of high-speed rail freight transportation, and in particular relates to a high-speed rail freight transportation data information management system and a dispatching management method thereof. Background Art

[0002] With the rapid development of global economic integration and e-commerce, the logistics industry is undergoing unprecedented changes. Especially in the field of railway freight, traditional freight methods have gradually failed to meet the needs of modern logistics for high efficiency, high reliability and full tracking.

[0003] According to the market research results on the transport organization model adopted by the three freight train test lines of Beijing-Wuhan, Zhengzhou-Chongqing, and Chengkun, it has not been able to give full play to the advantages of freight trains, especially because the three lines currently use purely manual loading and unloading methods, and the loading and unloading efficiency is relatively low. Therefore, in order to adapt to such loading and unloading needs, the three lines can only adopt an end-to-end transport organization model for freight trains, and cannot achieve full-load transportation throughout the journey by setting up intermediate stops according to the cargo transportation needs. Such a transport organization model, due to the lack of necessary flexibility, cannot meet the needs of the market and customers, and the transportation efficiency and benefits cannot be optimized. The common problem of the three test lines is the difficulty in organizing cargo sources and the inability to meet the transportation capacity needs of regular freight trains.

[0004] Railway freight, especially high-speed railway freight, has become an important part of the modern logistics system due to its large volume, low cost and environmental protection advantages. However, high-speed railway freight still faces many challenges and limitations in actual operation.

[0005] 1) Logistics informatization construction is relatively lagging behind From the perspective of the current railway logistics information system construction, due to the dispersion and differences of freight operators and their independence from each other, various independent and dispersed logistics information systems exist in parallel, and no unified railway logistics information platform has been formed, which makes it impossible to realize the integrated transportation data of railway logistics. At the same time, since the railway logistics information system is relatively closed and cannot be fully compatible with external social information systems, it is impossible to realize the sharing of logistics information and the tracking of logistics information throughout the process.

[0006] 2) Poor intermodal transport connectivity In view of the actual situation of railway logistics in terms of business model, infrastructure, information system, business process and operating standards, it is difficult for railway logistics to achieve seamless connection with other modes of transportation. The construction of logistics parks, seaports and the "last mile" is slightly lagging behind, and the cost of short-haul transportation is high, which will have a certain impact and restriction on the development of sea, water, road and railway combined transportation.

[0007] 3) Insufficient capacity for dispatching and integrating transport resources In recent years, although railway transportation has achieved relatively impressive results in releasing the capacity of existing lines, it faces problems such as insufficient loading and unloading capacity of freight stations and insufficient marshaling and unmarshaling capacity of marshaling yards. Due to the incomplete logistics functions of freight stations, especially the serious lack of containerization and mechanization of transportation equipment, some railway freight stations are far away from local cargo distribution centers, resulting in logistics island problems.

[0008] 4) Transport organization efficiency needs to be improved Due to the lack of organizational management capabilities in various links of transportation, untimely loading and unloading, train delays or untimely delivery are common, which will inevitably affect the delivery time of goods. At the same time, in the practice of railway transportation organization and management, in order to further improve the efficiency of transportation organization, we must also pay attention to the continuous optimization of the dispatching and command system.

[0009] 5) Railway transport capacity is not in line with market demand When designing railway transportation products, the railway department mostly starts from the transportation organization of the railway, and rarely designs transportation products in combination with customer needs, especially highlighting the personalized and customized product service needs. Therefore, among railway transportation products, there are few time-limited express products, containerized transportation products and full-process logistics service products that are adapted to market and customer needs, which to a certain extent restricts the competitiveness of railways in the freight market. Summary of the invention

[0010] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a high-speed rail freight data information management system and a scheduling management method thereof, which can not only realize the intelligent location perception management of high-speed rail freight trains, but also can intelligently manage the loading and unloading of containers, loading positions and vehicle-ground information interaction, so as to achieve the purpose of improving loading and unloading efficiency, optimizing resource scheduling, enhancing transportation organization efficiency and meeting market demand.

If an error occurs, an early warning message will be immediately sent to the freight data management system host and a loading error voice prompt will be issued.

[0055] (2) Uninstall the smart recognition function The management sub-host will follow the "unloading plan". When the loading and unloading personnel take the container out of the stacking area, the RIFD card reader will automatically identify the information of the container and confirm whether it is correct. If an error occurs, it will immediately send an early warning message to the freight data management system host and issue a voice prompt for unloading error.

[0056] The early warning information is uniformly confirmed and processed by the escort.
