Description

A Management Method and System for Rail-Water Intermodal Transport Based on Bulk Cargo Automated Warehouse Technical Field

[0001] This invention relates to the field of rail-water intermodal transport technology. More specifically, this invention relates to a management method and system for rail-water intermodal transport based on a bulk cargo automated warehouse. Background Technology

[0002] Railway bottom-opening cars, also known as self-unloading bottom-opening cars, have multiple downward-opening unloading doors at the bottom of the car body. They are mainly used for transporting bulk goods (such as coal, ore, sand, gravel, grain, etc.) and can achieve rapid unloading by relying on the weight of the goods themselves.

[0003] Currently, most rail-water intermodal transport stations using bottom-opening unloading systems are laid out in a horizontal configuration. The entire system consists of three parts: a railway operation area, a material distribution and buffer area, and a wharf operation area. Two belt conveyor systems, one for unloading and one for loading, connect the three operation areas. The railway operation area includes a station arrival / departure yard, unloading lines, freight car unloading pits, belt conveyors, and transfer stations. The arrival / departure yard is used to receive loaded cars, dispatch empty cars, and shunt loaded cars to the unloading lines. The unloading lines and the freight car unloading pits below are used to unload loaded cars. The belt conveyors and transfer stations within the unloading pits are responsible for transferring materials to the material distribution and buffer area.

[0004] The existing bottom-opening unloading process generally involves unloading bulk cargo arriving by rail in the railway operation area, then conveying it via a distribution conveyor belt to a distribution buffer area for sorting and storage. During loading, the corresponding bulk cargo for the ship is then conveyed from the distribution buffer area to the dock operation area via a loading conveyor belt. The existing bottom-opening material sorting system generally involves unloading bulk cargo arriving by rail in the railway operation area, then conveying it via a distribution conveyor belt to a distribution buffer area for sorting and storage. Material sorting is mainly achieved through distribution conveyor belts, transfer stations, and silos. The existing bottom-opening unloading process has the following main problems:

[0005] 1. Poor adaptability to complex terrains such as mountainous and hilly areas.

[0006] The existing planar layout is suitable for plain terrain. However, in complex terrain conditions such as mountains and hills where the elevation difference between different functional areas is 20-30m, the planar layout of each work area is often limited by the terrain conditions and cannot be well deployed. Land use is very limited. In difficult areas, it is often necessary to use belt conveyor corridors to connect the various functional areas. Once the length of the belt conveyor corridor reaches more than 20km, its operating cost and energy consumption are high, and the adverse characteristics of power supply difficulties in undeveloped mountainous and hilly areas become more prominent.

[0007] 2. Numerous functional zones, large footprint

[0008] The existing planar layout is divided into three operating areas: loading and unloading at both ends and buffer storage in the middle. There are many functional areas, especially the material distribution buffer area. Depending on the storage requirements, time, and type of transported goods, the material distribution buffer area, as a block of land, generally occupies an area of ​​100 to 300 acres. In complex terrain conditions such as mountainous and hilly areas, or in developed land conditions, it is often difficult to fully meet the land requirements of the material distribution buffer area. This has a significant limitation on the overall loading and unloading efficiency of the entire system and the ability to accommodate various types of goods.

[0009] 3. The functional areas are scattered and difficult to manage.

[0010] In existing horizontal layouts, railways are typically located behind the port area, with material distribution buffer zones and wharf operation areas adjacent to each other, and various functional areas scattered. As large-scale infrastructure for rail-water intermodal transport, the port area and railway are generally managed by different entities. Daily operation and maintenance coordination between them cannot achieve deep integration due to differences in management systems across industries. Advanced cases such as Ningbo-Zhoushan Port and Shenzhen Yantian Port have demonstrated that the key to truly bridging the "last mile" and maximizing transport efficiency in rail-water intermodal transport lies in whether the railway is included under the port area's jurisdiction. The existing horizontal layout naturally leads to multiple management entities, resulting in management inconvenience.

[0011] In recent years, automated bulk cargo warehouses have emerged, vertically integrating unloading lines and distribution silos by utilizing the elevation differences in hilly areas. When applied to rail-water intermodal transport stations, the upper railway serves as the silo for bottom-door freight cars to be distributed into the warehouse, while the lower section connects to a ship loader's belt conveyor system for loading onto ships. Previously, there was a lack of dedicated freight management methods for rail-water intermodal transport stations using automated bulk cargo warehouses. Summary of the Invention

[0012] The purpose of this invention is to provide a management method and system for bulk cargo automated warehouse rail-water intermodal transport. The system uses a bulk cargo rail-water intermodal transport management system for overall control, a railway transport management system for vehicle number and cargo identification, a port operation management system for ship and berth identification and control of ship loaders and conveyor belts, and a yard management system for inbound and outbound control and warehouse management. This enables the separation of different cargoes for different owners, saves investment in long-distance conveyor belts, and reduces intermediate operation time.

[0013] To achieve these objectives and other advantages according to the present invention, a method for managing rail-water intermodal transport based on bulk cargo automated warehouses is provided, comprising the following steps:

[0014] S1. Obtain the type and weight of goods from the transportation contract information and send it to the railway transportation management system;

[0015] S2. When loading goods, the loading information of freight trains is collected through the railway transportation management system, and a transportation plan is formulated and sent to the yard management system based on the loading information.

[0016] S3. After receiving the transportation plan, the yard management system formulates a storage allocation plan based on the current storage information.

[0017] S4. Obtain the storage allocation plan and send it to the railway transportation management system. According to the storage allocation plan, the railway transportation management system will send each car of the freight train to the unloading pit above the designated silo for unloading in sequence, and update the storage information.

[0018] S5. Based on the transportation contract information, issue loading instructions to the port operation management system and the yard management system. The port operation management system controls the port loading equipment to work, and the yard management system controls the corresponding warehouse feeder to output the goods, so as to achieve precise matching and transfer of ship and cargo until the loading operation is completed.

[0019] Among them, the loading information in S2 includes at least: the car number of each car, the type and weight of the loaded goods, and the owner information. The storage information in S3 includes the type and weight of the goods stored in each silo, as well as the owner information. When formulating the storage allocation plan, the cars are assigned to silos with the same owner information and goods type.

[0020] Among them, a vehicle number recognition device is installed at the unloading pit above each silo. After the car arrives at the unloading pit above the designated silo in S4, the yard management system obtains the car number of the car through the vehicle number recognition device. After it is successfully matched with the storage allocation plan, the system controls the car to start unloading.

[0021] The silo is equipped with a weighing device at the bottom. The railway transport management system in S4 obtains the changes in the weight of the goods in the silo through the weighing device to update the storage information.

[0022] The port operation management system receives the loading instruction and then verifies the identity information of the waterway vessel through the Automatic Identification System (AIS). Once the verification is successful, it controls the loading machine and loading conveyor belt to operate according to the loading instruction.

[0023] The present invention also provides a rail-water intermodal transport management system based on bulk cargo automated warehouse, including a rail-water intermodal transport management system, a railway transport management system, a port operation management system, and a yard management system;

[0024] The rail-water intermodal transport management system obtains the type and weight of goods from the transport contract information and sends it to the railway transport management system.

[0025] When goods are loaded, the loading information of freight trains is collected through the railway transportation management system, and a transportation plan is formulated and sent to the yard management system based on the loading information.

[0026] After receiving the transportation plan, the yard management system formulates a storage allocation plan based on the current warehouse storage information;

[0027] The rail-water intermodal transport management system receives the storage allocation plan sent by the yard management system and sends it to the railway transport management system. According to the storage allocation plan, the railway transport management system delivers each car of the freight train to the unloading pit above the designated silo for unloading and updates the storage information.

[0028] Based on the transportation contract information, the rail-water intermodal transport management system issues loading instructions to the port operation management system and the yard management system. The port operation management system controls the operation of the port loading equipment, and the yard management system controls the corresponding warehouse feeder to output the goods, so as to achieve precise matching and transfer of ships and cargo until the loading operation is completed.

[0029] The railway transport management system includes a cargo identification module and a car number identification module. The loading information includes at least the car number of each car, the type and weight of the cargo loaded, and the cargo owner information. When loading cargo, the cargo identification module collects the type and weight of the cargo loaded in each car, as well as the cargo owner information, and the car number identification module collects the car number of each car. When the railway transport management system formulates a storage allocation plan, it allocates the car to a silo with the same cargo owner information and cargo type.

[0030] Each silo is equipped with a vehicle number recognition device at the unloading pit above it. After the truck arrives at the designated unloading pit above the silo, the yard management system obtains the truck number through the vehicle number recognition device. Once the number matches the storage allocation plan, the system controls the truck to start unloading.

[0031] The silos are equipped with weighing devices at the bottom. The railway transport management system uses these devices to obtain information on changes in the weight of goods inside the silos in order to update the storage information.

[0032] The port operation management system receives the loading instruction and then verifies the identity information of the waterway vessel through the Automatic Identification System (AIS). Once the verification is successful, it controls the loading machine and loading conveyor belt to operate according to the loading instruction.

[0033] The beneficial effects of this invention are:

[0034] (i) The accuracy of bulk cargo sorting has been significantly improved.

[0035] By linking wagon numbers with cargo status in the railway transport management system, accurately matching ships and cargo in the port operations management system, and scheduling dedicated unloading pits and partitioned storage in the yard management system, the entire process of physical isolation and accurate identification of different cargo owners and cargo types is achieved. From the source of railway unloading to waterway loading and yard storage, the problems of mixed materials and incorrect unloading are effectively avoided, the accuracy of material sorting is improved, and the differentiated material sorting needs of multiple cargo owners and multiple cargo types are met.

[0036] (ii) Work efficiency has been greatly improved

[0037] Automated operations reduce human intervention: Automatic car number recognition and hydraulic rod linkage control at the railway end, automated control of ship loaders at the waterway end, and intelligent control of the outlet feeder at the yard end have realized automated operations in loading, unloading, and transfer, completely eliminating dependence on manual operation and shortening the operation time of each link.

[0038] End-to-end collaboration shortens turnaround time: The main system for rail-water intermodal transport management coordinates information and dispatches instructions for rail, water, and storage yard links, eliminating information silos between links, reducing the turnaround time of goods from unloading on the rail to loading on the water, and significantly improving overall operational efficiency.

[0039] (iii) Operating costs have been significantly reduced.

[0040] Hardware investment cost savings: The natural elevation difference between the unloading area and the silo enables bottom-opening trucks to distribute materials, eliminating the need for investment in long-distance belt conveyor equipment and reducing hardware costs; the zoned storage design also reduces investment in additional warehousing facilities.

[0041] Operational cost optimization: Automated operations reduce labor costs; collaboration among systems reduces material loss and energy consumption during intermediate transfers, resulting in an overall reduction in operating costs.

[0042] (iv) Upgrading the level of system synergy and intelligence

[0043] The three subsystems—railway transport management, port operation management, and yard management—interact with the main system in a closed loop, enabling real-time information collection, processing, and instruction feedback. This achieves intelligent overall scheduling of the entire rail-water intermodal transport process. The system can automatically adjust its operational plans based on dynamic information such as cargo owner needs, warehouse status, and ship arrivals, demonstrating a high degree of adaptability and collaboration. This provides a technological paradigm for the intelligent upgrading of bulk cargo rail-water intermodal transport.

[0044] (v) Outstanding industry application value

[0045] This technology provides a precise and efficient end-to-end solution for bulk cargo rail-water intermodal transport, which can be widely applied to rail-water intermodal transport scenarios for bulk cargo such as ore and coal. It promotes the industry's transformation from traditional manual material sorting and decentralized scheduling to intelligent and integrated management, improves the overall operational efficiency of the industry, and has significant economic and social benefits.

[0063] After receiving the transportation plan, the yard management system formulates a storage allocation plan based on the current warehouse storage information;

[0064] The rail-water intermodal transport management system receives the storage allocation plan sent by the yard management system and sends it to the railway transport management system. According to the storage allocation plan, the railway transport management system delivers each car of the freight train to the unloading pit above the designated silo for unloading and updates the storage information.

When loading cargo, the cargo identification module collects the type and weight of the cargo loaded in each car, as well as the cargo owner information, and the car number identification module collects the car number of each car. When the railway transport management system formulates a storage allocation plan, it allocates the car to a silo with the same cargo owner information and cargo type.

[0067] Each silo is equipped with a vehicle number recognition device at the unloading pit above it. After the truck arrives at the designated unloading pit above the silo, the yard management system obtains the truck number through the vehicle number recognition device. Once the number matches the storage allocation plan, the system controls the truck to start unloading.

[0068] The silos are equipped with weighing devices at the bottom. The railway transport management system uses these devices to obtain information on changes in the weight of goods inside the silos in order to update the storage information.

Once the verification is successful, it controls the loading machine and loading conveyor belt to operate according to the loading instruction.

[0070] As shown in Figure 1, an embodiment of the present invention also provides a bulk cargo automated warehouse rail-water intermodal transport management system, comprising three core subsystems: a rail-water intermodal transport management system, a railway transport management subsystem, and a port operation management subsystem, and a yard (warehousing) management subsystem. Each subsystem works collaboratively through data interaction, and the specific configuration is as follows:

[0071] 1. Railway Transportation Management System

[0072] According to the instructions of the rail-water intermodal transport management system, it is responsible for receiving goods at the railway end, identifying goods, loading and unloading vehicles, and managing transportation. It also uploads real-time information on loading, unloading, and transportation of goods to the rail-water intermodal transport management system. It includes the following units:

[0073] (1) Cargo identification unit

[0074] Cargo identification module: During the cargo loading stage at the loading station, the module obtains loading information such as cargo type (e.g., coal, ore, and variety), cargo owner name, cargo batch, and cargo weight of the car through inbound data, warehouse number, cargo location number, outbound cargo image sensor data verification or manual assistance, and uploads it to the railway transportation management system in real time.

[0075] During the unloading stage at the unloading station, the types of goods to be unloaded by vehicles entering the designated unloading pit are checked, and the weight of the goods unloaded by the vehicles entering the designated pit (cargo location) is checked to ensure that the weight is correct.

[0076] (2) Vehicle number recognition module:

[0077] Car number recognition equipment (such as high-definition cameras and radio frequency identification devices AEI) is installed in the cargo loading area. The car number recognition equipment automatically collects the car number and confirms the unique car number of each railway car loaded with cargo. This realizes the binding of the car number with the type of cargo, cargo name, and cargo owner information, achieving "one car, one code, one file" and uploading it to the railway transportation management system for use in the entire process of railway transportation and loading / unloading of cargo.

[0078] Vehicle number recognition equipment (such as high-definition cameras and radio frequency identification devices AEI) is installed at points such as the entrance of the unloading track and the unloading pit (cargo location) to automatically collect vehicle numbers and upload them to the railway transportation management system for warehousing control and storage management in the unloading bin warehouse.

[0079] 2. Port Operations Management System (Terminal Operating System TOS)

[0080] According to the instructions of the rail-water intermodal transport management system, it is responsible for identifying vessels and berths on the waterway side, controlling material transfer and loading, and uploading the operation process and progress to the rail-water intermodal transport management system. The port operation system includes the following units:

[0081] (1) Ship Identification Unit

[0082] The Automatic Identification System (AIS) is used to automatically identify the identity information of water transport vessels. Each berth is equipped with image recognition to identify the berth where the vessel is docked and to confirm its operational status. Vessel information and operational progress are uploaded to the port operation management system to ensure the traceability of goods in the water transport process and the monitoring of operational status.

[0083] (2) Ship loader control unit

[0084] Loading of bulk cargo onto ships is carried out in accordance with instructions from the port operations management system.

[0085] (3) Belt conveyor control unit (including conveyor module)

[0086] Based on instructions from the port operations management system, the system controls the conveyor belt material transport process, connects with the material transfer operations at the water transport end, and coordinates with the loading process to achieve efficient and precise material delivery. Data such as the operation process, progress, and types and weights of transported goods are uploaded to the port operations management system.

[0087] 3. Storage Yard (Silo) Management System

[0088] The storage yard (silo) management system consists of three parts: storage location management unit, inbound control unit, and outbound control unit.

[0089] It receives in-transit railway freight data and periodic warehousing requests from the railway transport management system, and receives periodic ship cargo loading plans from the port operation management system. Based on the type, quantity, weight, and owner of the goods, it dynamically arranges the periodic silo space usage plan and uploads the periodic plan to the rail-water intermodal transport management system.

[0090] According to the instructions of the rail-water intermodal transport management system, it is responsible for receiving goods imported by rail, exporting goods to ships at the port, rationally arranging silo storage locations, supervising the control of storage yard locations and export materials, and uploading the operation process, progress and storage data to the rail-water intermodal transport management system.

[0091] (1) Warehouse Management Unit

[0092] The warehouse management unit consists of a warehouse management module, a silo inbound vehicle identification module, and a warehouse status monitoring module, which monitors the warehouse status (including material type, storage quantity, etc.) of the silos in the storage yard in real time.

[0093] Warehouse Management Module: Receives storage and outbound plans from the rail-water intermodal transport management system, rationally allocates warehouse locations (cargo locations), and, based on the storage and export plans, directs the inbound control unit to receive goods and the outbound control unit to output goods, while continuously monitoring changes in cargo locations;

[0094] Silo entry vehicle identification module: Adopting a "pre-positioned yard" design, a vehicle number identification device is installed at the unloading pit of each silo, and the vehicle number is uploaded to the warehouse management unit;

[0095] Storage monitoring module: The unloading pit is directly connected to the bulk cargo silo (storeyard) (using the height difference to enable the goods to slide down naturally or be transported over short distances), and the storage area (silo number) is divided for the cargo owner and cargo type to achieve physical isolation storage for different cargo owners and cargo types;

[0096] Install storage monitoring equipment in each silo to dynamically monitor the status of unloading into the warehouse and loading onto ships, as well as the static storage location.

[0097] (2) Warehouse entry control unit

[0098] The warehouse control unit is equipped with a controllable railway bottom-opening freight car door opening control lever at each unloading pit (warehouse entrance). When the control lever is raised, it touches the warehouse door switch of the moving vehicle to open the bottom of the warehouse and unload materials into the warehouse at the unloading pit. When the control lever is lowered, the vehicle closes the bottom of the warehouse and passes through the unloading pit.

[0099] Each unloading pit is equipped with a hydraulic rod adapted to vehicles with bottom-opening doors. According to the instructions of the cargo location entry control unit, the hydraulic control module and the vehicle number recognition module work together. When the vehicle number matches and verifies the designated pit, the "lift hydraulic rod" command is output to trigger unloading; when the vehicle number does not match the designated pit command, the "lower hydraulic rod" command is output, and the vehicle continues to move to the designated pit.

[0100] (3) Outbound control unit

[0101] The outbound control unit is equipped with a feeder and weighing device at the bottom outlet of each silo to control the outbound feeder and materials, and to complete the accurate output and supervision of goods from the storage yard (silo) to the delivery stage.

[0102] The rail-water intermodal transport management system connects the "receiving (goods entering the site)" and "delivery" stages through the coordinated operation of three subsystems, enabling efficient material distribution for different cargo owners and goods, significantly saving investment in long-distance conveyor belts, shortening intermediate operation time, and meeting the technical requirements for precise management of bulk cargo.

[0103] This system, through the coordinated operation of three subsystems, realizes the full-process bulk cargo transportation function from "receiving - cargo entry - loading identification - railway transportation - unloading control - warehousing matching - shipping - delivery". The specific functions are as follows:

[0104] 1. Railway Transportation Management System

[0105] Focusing on cargo loading, unloading, identification, and scheduling at the railway end, precise control over the source of materials is achieved:

[0106] Automatic cargo status and vehicle number association function: During the loading process, the cargo type, cargo owner information and vehicle number are automatically identified and bound, and electronic data of transport bills and waybills are established, providing basic data support for subsequent cargo identification, transportation, yard buffering and ship loading operation scheduling.

[0107] 2. Port Operations Management System

[0108] Responsible for identifying vessels and berths at the water transport end, controlling loading, and matching cargo to ships; connecting material transfer between storage yards (silos) and vessels.

[0109] Vessel and berth identification function: Automatically identifies the identity of water transport vessels berthed at the dock and their berths, ensuring the traceability of goods in the water transport process.

[0110] Ship loader control function: Intelligent control of the ship loader's operation process to achieve precise loading of materials from the stockyard to the ship based on cargo type and weight.

[0111] Precise ship-cargo matching function: Links shipping demand with yard inventory information to generate a ship-cargo matching list, providing a basis for the transfer of goods from the yard to the ship, reducing intermediate transfer links and shortening cargo turnaround time.

[0112] 3. Storage Yard (Silo) Management System

[0113] Responsible for cargo warehousing planning, cargo receiving, segregation, warehouse location monitoring, and export control, ensuring the independence and accuracy of cargo output after sorting.

[0114] Precise unloading route scheduling function: Based on the elevation difference of the unloading area, the layout of the lanes and the storage needs, a dedicated unloading pit is assigned to each vehicle to avoid mixing of vehicles of different types of goods and owners during the unloading process, and to ensure the accuracy of material distribution source.

[0115] Vehicle number accurate identification and verification function: The identification device automatically collects the vehicle number and compares it with the data in the central database to ensure that the vehicle entering the unloading pit is consistent with the material distribution requirements, and to prevent incorrect or mixed unloading.

[0116] Controllable hydraulic control lever linkage control function: Based on the vehicle number verification result, the hydraulic lever is automatically controlled to raise and lower, realizing the automated control of "unloading when in position and moving forward when not in position" for bottom-opening vehicles, without the need for manual intervention in the unloading action, thus improving material distribution efficiency.

[0117] Dedicated cargo storage function: Based on the "pre-positioning of the yard + zoned storage" design, it can accept goods unloaded from the unloading pit, realize the physical isolation storage of different cargo owners and different types of goods, and ensure the independence of goods after sorting.

[0118] Storage location monitoring and identification function: Real-time monitoring and identification of storage location status (including material type, storage quantity, etc.) of storage yard silos, providing data support for storage management and subsequent scheduling.

[0119] Export feeder control function: Integrates export feeder control and other modules to achieve precise output of goods from the yard to subsequent stages, ultimately achieving the distribution and delivery of goods from different cargo owners.

[0120] As shown in Figure 2, the above-mentioned bulk cargo automated warehouse rail-water intermodal transport management system achieves precise bulk cargo allocation through information exchange and collaborative operations between the railway transport management system, port operation management system, yard management system, and the main system. The specific steps are as follows:

[0121] Step 1: Receiving Goods. The rail-water intermodal transport management system receives the transport contract and notifies the railway transport management system to receive bulk goods according to the type and quantity of goods identified in the transport contract. The goods are then buffered in the designated storage locations and loading warehouses.

[0122] During the receiving process, information on the type, quantity, and location of goods received by the railway transportation management system is collected, and the goods information is uploaded to the rail-water intermodal transport management system.

[0123] Step 2: Loading and Information Collection: During the loading process, the railway transport management system collects the car number, cargo type, weight, and cargo owner information of the railway loading vehicles through the railway car number identification module, loading warehouse identification module, or manual assistance, and uploads this information to the main rail-water intermodal transport management system.

[0124] Operation execution: The railway transport management system collects relevant cargo and owner information and uploads it to the main rail-water intermodal transport management system. The rail-water intermodal transport management system then generates a transport plan and issues it to the yard management system.

[0125] Step 3: Information collection and operation execution for yard-end storage receiving and export

[0126] The storage yard management system receives the transportation plan from the rail-water intermodal transport management system, specifies a phased storage allocation plan based on the current storage occupancy status and the transportation plan, and uploads it to the rail-water intermodal transport management system; the rail-water intermodal transport management system then forwards the storage allocation plan to the railway transport management system.

[0127] When railway vehicles arrive, the railway transport management system delivers them to the designated unloading pits according to the warehousing plan; the warehousing management system controls the bottom door control levers of the railway vehicles to unload them into the designated warehouses according to the warehousing allocation plan.

[0128] Main system processing: After receiving the information, the main system combines the unloading and material distribution results at the railway end with the cargo demand at the waterway end to generate warehouse management instructions and export feeder control instructions.

[0129] Operation Execution: After receiving instructions from the main system, the railway transport management system assigns dedicated unloading pits to the vehicles; the vehicle identification system verifies the vehicle's identity and automatically controls the hydraulic rods to complete the unloading of bottom-opening freight cars, achieving precise material sorting and unloading operations at the railway end. After receiving instructions, the yard management system divides and isolates goods of different owners and different types of goods for storage; during the unloading process, the yard management system continuously collects information on the status of silos (type of goods, storage quantity) and the status of the exit feeder through the silo location identification module and silo location monitoring module, and uploads this information to the main rail-water intermodal transport management system.

[0130] Step 4: Information collection and operation execution for vessels entering the waterway terminal

[0131] Information Collection: The port operations management system identifies waterway transport vessels based on transportation contracts, collects the identity information of berthed vessels through the vessel identification module (AIS), and determines the vessel's berth through the berth monitoring module. This information is then uploaded to the main rail-water intermodal transport management system.

[0132] Main system processing: After receiving the information, the main system retrieves the storage information (including cargo type and quantity) uploaded by the yard management system, generates a ship-cargo matching list and material transfer instructions, and uploads the operation instructions to the rail-water intermodal transport management system;

[0133] The rail-water intermodal transport management system issues loading instructions to the port operation management system and the yard management system according to the transport contract. The yard management system issues loading instructions to the silo feeder of the designated cargo. The silo feeder starts discharging material and monitors the type and quantity of the output cargo and the silo location, and uploads the data to the rail-water intermodal transport management system.

[0134] Operation execution: After receiving the loading instruction, the port operation management system controls the operation of the loading machine and coordinates the material transportation process of the belt conveyor and transfer station. At the same time, it monitors the types and quantities of goods loaded in real time and uploads them to the rail-water intermodal transport management system. The yard management system receives the loading instruction in sync and dispatches the feeder of the corresponding warehouse to output the goods, so as to achieve precise matching of ship and cargo and transfer operations until the loading operation is completed.

[0135] Step 5: Delivery

[0136] Once the ship loader completes the loading operation, it reports the operation status to the port operation management system and then to the rail-water intermodal transport management system. At the same time, the yard management system uploads the silo operation data and status to the rail-water intermodal transport management system.

[0137] Once the rail-water intermodal transport management system receives information that cargo loading is complete, it delivers the cargo to the cargo owner through electronic systems and on-site operational evidence, thus completing the contract.

[0138] This operational method collects information from each of the three subsystems—railway, storage yard, and waterway—and uploads it to the main system. The main system then processes the information and issues execution instructions to each subsystem, achieving information collaboration and operational coordination throughout the entire rail-water intermodal transport process. Ultimately, this results in precise distribution of bulk cargo, saving on long-distance conveyor belt investment and shortening intermediate operation time.

[0139] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application, and should all be covered within the scope of the claims of this application.
