Description

Technical Field

[0001] The present invention relates to the fields of transportation and logistics, and in particular to an automated logistics distribution system for urban rail transit based on passenger and freight co-transportation. Background Art

[0002] At present, with the advancement of urbanization in my country, the continuous development of cities and the rapid expansion of e-commerce, the demand for urban logistics has surged. The huge demand for logistics has led to a continuous increase in urban traffic volume, and the pressure on ground transportation has become increasingly greater. The resulting increase in urban transportation costs and traffic congestion, as well as the resulting environmental pollution and noise hazards, have seriously restricted urban development and affected the daily lives of urban residents. In addition, residents' demand for logistics and distribution has shifted from safe delivery to fast, timely, and safe delivery of express delivery. Delivery speed has become a core competitive advantage in the logistics industry. While subways are not only fast and more environmentally friendly than road transportation, they also have long off-peak periods during normal operating hours, resulting in significant excess capacity. This invention improves urban logistics and distribution efficiency, alleviates urban traffic congestion, reduces the negative impact of logistics activities on cities, and reduces carbon emissions by utilizing the excess capacity of urban subway operations during non-peak hours, while avoiding the impact on passengers during peak hours. The subway-based intelligent rail logistics system combines road and rail transportation to meet people's daily needs for short-distance delivery.

[0003] With the continuous development of cities and the rapid growth of e-commerce, demand for urban logistics has surged. However, current urban logistics issues include long intra-city delivery times and high costs. People's demands for logistics and delivery have evolved beyond safe delivery to include speed and timeliness. Delivery speed has become a core competitive advantage in the logistics industry. To alleviate the pressure on intra-city logistics, leveraging the current surplus subway capacity during off-peak periods, we are conducting micro-renovations at subway stations. We are designing equipment tailored to the specific needs of each system and deploying logistics equipment outside stations, in concourses, on platforms, and in subway cars. This automated logistics infrastructure enables the automated movement of goods. This creates a fully automated, intelligent subway logistics and transportation system to meet this growing demand. This intelligent logistics system effectively addresses multiple challenges, including the high pressure of intra-city logistics, high delivery costs, wasted subway capacity, and urban traffic congestion, while also reducing energy consumption and carbon emissions.

[0058] Compared with the prior art, the embodiments of the present invention achieve the following beneficial effects:

[0059] An embodiment of the present invention also provides an automated logistics distribution system for urban rail transit based on the combined transportation of passengers and freight. The system sets up smart storage and retrieval cabinets outside the subway station for customers and logistics companies to store and retrieve goods. Goods are transported from the station entrance to the subway station platform by an aerial cart. A cargo distribution area is set up at the platform and equipped with an automated guided vehicle (AGV). After the goods are transported to the shelf, the automated guided vehicle (AGV) lifts the entire shelf and transports it to the last car of the subway. There are fixed shelves inside the last car. The incoming mobile shelves are sorted and stored by stackers. The operation scheduling system monitors the capacity of smart storage and retrieval cabinets and shelves to balance the relationship between cargo flow and passenger flow. This system can greatly reduce the cost of freight, reduce ground traffic pressure, and reduce carbon emissions. It makes people's lives more convenient and improves people's living standards.

[0060] The present invention solves the problem of determining when the transported goods are delivered to the subway station.

[0061] This invention addresses the shortcomings of other solutions, such as poor data communication and the inability to achieve effective collaboration. By building a big data internet platform, data interoperability is achieved. Utilizing intelligent storage and retrieval technology, it addresses the labor-intensive nature of traditional storage and retrieval systems. Ground-level intelligent storage and retrieval cabinets are located close to subway station entrances, serving as temporary warehouses for goods. These cabinets facilitate customer access to platforms, as well as the transport of goods via the overhead rail system. The use of overhead vehicles addresses the existing challenges of subway transportation research, improving logistics efficiency and reducing passenger and freight interference. These solutions facilitate customer access to platforms, as well as the transport of goods via the overhead rail system, without occupying ground space and disrupting the normal flow of urban rail transit, ensuring the safety of both pedestrians and goods. Automated Guided Vehicles (AGVs) enable the transport of goods and shelves into train carriages as a whole, facilitating transfers within the same station, reducing route conflicts between vehicles, and shortening travel time. In terms of cargo safety, this project, compared to existing solutions, adopts a passenger and freight separation approach, employing flexible train formations, with freight cars at the rear of the train and dedicated freight areas on the platform, addressing cargo safety concerns. At the same time, it improves the existing solutions and solves the problem of cargo sorting that cannot be solved. By installing intelligent stacking cranes in special freight cars and implementing the first-in-first-out principle, cargo can be sorted while the train is running, thereby improving the cargo sorting efficiency.

[0062] This invention can fully utilize the density advantage of urban subways and the excess capacity during off-peak periods to carry out intra-city or inter-city transportation and distribution, alleviate the pressure of road logistics distribution, increase the utilization rate of subway cars during idle time, empower energy conservation and emission reduction, and facilitate people's lives.

[0068] A smart locker includes multiple cargo boxes. The multiple smart lockers include a first smart locker and a second smart locker. The aerial trolley structure includes an aerial trolley and an aerial guide rail. One aerial trolley structure corresponds to one subway platform structure, one subway car automated storage equipment corresponds to one subway station.

[0069] The aerial vehicle used in this embodiment is an EMS aerial vehicle.

[0070] The subway station is a fixed subway station for rail transit.

[0071] The operation system is further used to obtain cargo information stored in the first smart storage and access cabinet; the cargo information includes the destination location and cargo category of the cargo; the operation system is further used to obtain the cargo location in real time.

[0072] The subway platform structure includes an automatic navigation vehicle, an automated equipment charging area, and a platform cargo distribution area; the platform cargo distribution area includes multiple shelves.

[0073] Wherein, the shelf is a movable shelf.

[0074] The operation system is also used to control the aerial vehicle to take out the goods stored in the first intelligent storage and retrieval cabinet and transport them to the shelves.

[0075] The aerial guide rail passes through the station hall, and the aerial trolley also passes through the station hall when transporting goods.

[0076] The operation system is used to send a signal to the automatic navigation vehicle after receiving a signal that the goods are on the shelf and a signal that the subway operation status is the arrival at the station, controlling the automatic navigation vehicle to lift the shelf and transport it to a dedicated freight car.

[0077] Among them, the dedicated freight car is the last car of the subway where the automated warehousing system is deployed.

[0078] Among them, the Automated Guided Vehicle (AGV).

[0079] The automated storage equipment in the subway carriage is arranged inside a dedicated freight carriage; the automated storage equipment in the subway carriage includes two stackers and multiple fixed shelves; the exit points on a fixed shelf are the same;

[0080] The fixed rack is a rack that can be moved inside a subway car. The exit points on a fixed rack are the same.

[0081] The operation system is also used to plan routes based on the location of goods, destination of goods, and subway operation status by constructing circles and clustering methods to obtain exit stations. One exit station corresponds to one shelf.

[0082] Among them, one shelf marks one exit station. When arriving at the exit station, the marked shelf will be transported out of the subway from the automated storage equipment in the subway car.

[0083] The operation system controls the stacker crane according to the outbound station to sort and store the items on fixed shelves.

[0084] The operation system is also used to, when receiving a signal that the cargo location has arrived at the exit site, control the automatic navigation vehicle to transport the fixed shelf where the cargo corresponding to the exit site is located to the platform of the exit site, and control the aerial vehicle to transport the cargo to the second smart storage and retrieval cabinet.

[0085] Optionally, the operation system is further configured to plan a route based on the cargo location, cargo destination, and subway operation status by constructing a circle and clustering method to obtain an exit station, including:

[0086] The operation system is used to perform the following steps:

[0087] Obtain a subway route map, multiple subway station locations, and multiple idle smart lockers; the idle smart locker number represents the total number of unstored cargo boxes in the smart lockers that can be reached from the exit station; one exit station corresponds to one idle smart locker number.

[0088] The smart locker location represents the geographical location of the smart locker.

[0089] Compare the cargo destination and cargo location to obtain the exit station. Multiple exit stations are obtained for multiple cargoes.

[0090] The exit station is accessible by the subway route where the target location is located, and is the subway station location closest to the destination location of the goods on the subway route map.

[0091] Among them, based on the cargo location and transportation map, the stations that the cargo can pass through are obtained; based on the cargo destination location, the distance to the station is calculated, the shortest distance is obtained, and this station is set as the exit station.

[0092] According to the exit site, a site adjacent to the exit site that the subway route can pass through is found to obtain an adjacent site.

[0093] The adjacent station is the previous station or the next station of the exit station on the subway line.

[0094] Circles are drawn with the adjacent station and the exit station as the centers respectively, to obtain the overlapping cargo set, the non-overlapping cargo set and the cargo set outside the circle; the overlapping cargo set includes the cargo in the overlapping area between the two circles; the non-overlapping cargo set includes the cargo in the non-overlapping area between the two circles; the cargo set outside the circle represents the cargo corresponding to the cargo destination location whose distance to the exit station is less than the distance to other stations and is not within the two circles.

[0095] The radius of the circle is 2 / 3 of the distance between the two subway stations.

[0096] The goods are bound to the outbound site or adjacent site based on the overlapping cargo set, non-overlapping cargo set, out-of-circle cargo set, and the idle number of smart storage and retrieval cabinets.

[0097] Optionally, the binding of cargo to an outbound station or an adjacent station according to the overlapping cargo set, the non-overlapping cargo set, the out-of-circle cargo set, and the number of free smart lockers includes:

[0098] Determine whether the number of elements in the non-overlapping goods set is greater than the number of free smart lockers;

[0099] Among them, if the number of elements in the non-overlapping cargo set is less than or equal to the number of free smart access cabinets, it means that the free positions in the smart access cabinets that can be reached by the exit site can store all the outbound cargo; if the number of elements in the non-overlapping cargo set is greater than the number of free smart access cabinets, it means that the free positions in the smart access cabinets that can be reached by the exit site cannot store all the outbound cargo.

[0100] If the number of elements in the set of non-overlapping goods is greater than the number of free smart lockers, the exit site is used as the cluster center, and the destination location of the goods within the circle corresponding to the exit site and the number of free smart lockers are used as the end conditions to perform clustering to obtain a cluster location set; the cluster location set includes the locations corresponding to the goods leaving the exit site;

[0101] The clustering algorithm used in this embodiment is the k-means clustering algorithm.

[0102] Among them, the locations in the cluster set are close, which can make distribution more convenient.

[0103] Bind the cargo corresponding to the locations in the clustered location set to the outbound station.

[0104] The cargo destination locations within the circle corresponding to the outbound station, excluding the cargo destination locations in the clustered location set, form an unclustered set;

[0105] Based on the non-clustered set, overlapping cargo set, non-overlapping cargo set, and out-of-circle cargo set, the cargo is bound to the outbound station or adjacent station.

[0106] Through the above operation system, the values ​​in the circle are clustered, and the location of the smart cabinet is determined based on the overlap, clustering and the number of free smart cabinets.

[0107] Optionally, the step of binding cargo to an outbound station or adjacent station based on the non-clustered cargo set, the non-overlapping cargo set, the overlapping cargo set, and the out-of-circle cargo set includes:

[0108] Bind the outbound stations to the cargoes that exist in the unclustered set and that correspond to the locations in the non-overlapping cargo sets;

[0109] Bind the adjacent sites to the cargoes that exist in the unclustered set and that correspond to the locations in the overlapping cargo set;

[0110] If the number of elements in the unclustered set of the outbound site is greater than or equal to the number of elements in the unclustered set of the adjacent site, the outbound site is taken as the first site;

[0111] If the number of elements in the unclustered set of the neighboring site is greater than or equal to the number of elements in the unclustered set of the outbound site, the neighboring site is used as the first site;

[0112] Bind the goods corresponding to the location of the goods collection outside the circle to the first site.

[0113] As shown above, since the number of available smart lockers at the outbound station has been reserved for goods in the clustered location set, a decision is made as to whether to leave the excess goods at the outbound station or place them at an adjacent station. If the goods are in the non-clustered set and do not overlap with the set, placing them at an adjacent station will result in a long pickup distance, so they are placed at the outbound station and wait for a free station. If the goods are in the non-clustered set and overlap with the set, the pickup distance to the adjacent station is sufficient, so they are placed at the adjacent station. However, for goods outside the circle, the distance to both the outbound station and the adjacent station is long, so the station with the smaller distance between the outbound station and the adjacent station is chosen.

[0114] Optionally, if the number of elements in the non-overlapping cargo set is less than or equal to the number of free smart lockers, the cargo is bound to an outbound station or an adjacent station, including:

[0115] Subtract the number of non-overlapping goods from the free number of the smart lockers to obtain the first free number.

[0116] The first idle quantity indicates the number of idle cargo boxes in the smart storage and retrieval cabinet after adding cargo corresponding to the non-overlapping cargo set.

[0117] If the number of elements in the overlapping cargo set is greater than the first free quantity, the overlapping cargo set is arranged according to the size of the distance from the exit site, and the overlapping cargo set is bound to the exit site in ascending order of distance from the exit site until the bound overlapping cargo set is equal to the first free quantity.

[0118] The fact that the number of elements in the overlapping cargo set is greater than the first free quantity indicates that all cargo corresponding to the overlapping cargo set can be placed in the free cargo boxes of the smart storage and retrieval cabinet.

[0119] Bind the unbound overlapping cargo sets and the cargo sets outside the circle to adjacent sites;

[0120] Among them, the remaining overlapping cargo sets of the unbound exit stations that are too long from the roadside of the exit stations and the cargo corresponding to the cargo sets outside the circle are bound to adjacent stations.

[0121] If the number of elements in the overlapping cargo set is equal to the first free quantity, the overlapping cargo set is bound to the outbound station, and the out-of-circle cargo set is bound to the adjacent station;

[0122] If the number of elements in the overlapping cargo set is less than the first free quantity, the cargo set outside the circle is bound to the outbound station and the station with the larger free quantity of smart lockers among the adjacent stations.

[0123] If the number of free smart lockers at the exit station is greater than the number of free smart lockers at the adjacent station, the outbound cargo collection will be bound to the exit station. If the number of free smart lockers at the adjacent station is greater than the number of free smart lockers at the exit station, the outbound cargo collection will be bound to the adjacent station.

[0124] Optionally, a smart screen is included in the center of the smart locker.

[0125] Wherein, the smart storage and access cabinet is fixed outside the subway station.

[0126] The smart screen is used to receive the shipping address information input by the user; the smart screen is used to send the shipping address information to the operation system;

[0127] The operating system is also used to control the smart storage and retrieval cabinet to produce a QR code label and attach it to the cargo box based on the cargo in the cargo box and the shipping address information; the QR code label is used to scan the QR code label with a smartphone when receiving the goods.

[0128] Among them, smart lockers on the ground store and identify goods that customers or logistics companies need to transport. Smart lockers outside subway stations are equipped with cargo boxes, and a central smart screen allows users to send and receive packages by scanning codes. When sending a package, users enter their shipping address on the touchscreen display. The controller receives the shipping address and writes it to the operations system. The operations system creates a QR code label based on the contents and destination and affixes it to the box. When receiving a package, users scan the QR code label with their smartphone.

[0129] Optionally, the aerial guide rail sets a circular track in the station hall of the subway station and sets a circular track in the platform of the subway station; the two circular tracks are connected by a single track.

[0130] Among them, the circular track of the station hall and the exit are also connected by a single track.

[0131] The aerial trolley runs on an aerial monorail; one aerial trolley transports one cargo box;

[0132] The aerial trolley passes through the station hall via an aerial track and transports cargo boxes between the smart storage and retrieval cabinets and the platform cargo distribution area.

[0133] The operation system is also used to control the aerial vehicle to transport the goods from the first intelligent storage and retrieval cabinet to the shelves in the platform cargo distribution area; the shelves temporarily store the cargo boxes.

[0134] The circular track is laid along the wall.

[0135] Among them, the operation system receives the signal that the fixed shelf has arrived at the destination, and controls the automatic navigation vehicle in the compartment to transport it to the platform cargo distribution area at the destination;

[0136] A security inspection device is provided at one end of the circular track; the security inspection device is used to inspect incoming and outgoing cargo boxes.

[0137] After sorting is complete and the train arrives, the AGV transports the mobile racks to the station's platform distribution center. Once the cargo boxes arrive at the designated exit platform, they are transported along the track by EMS aerial vehicles to smart lockers outside the station. Upon arrival at the lockers, a notification is sent to the courier or recipient. The courier uses this information to retrieve the goods from the lockers and make final delivery. The recipient must collect their goods within a specified timeframe.

[0138] The above structure has the advantages of more convenient transfer at the same station, reduced route conflicts between vehicles, and shortened travel time of vehicles.

[0139] Optionally, the platform cargo distribution area is located on one side of the platform where the dedicated freight cars are parked; and the multiple shelves in the platform cargo distribution area are used to place incoming and outgoing cargo boxes.

[0140] Among them, the dedicated freight car is the last car of the subway where the automated warehousing system is deployed.

[0141] The automatic navigation vehicle is stored on the other side of the platform relative to the platform cargo distribution area.

[0142] The automatic navigation vehicle and the platform cargo distribution area are on the same side of the subway when getting on or off the train, but they are directly opposite each other.

[0143] Charging piles are set up in the automation equipment charging area; the charging piles are used to provide battery life for the automatic navigation car;

[0144] The operation system is also used to control the automatic navigation vehicle to run to the platform cargo distribution area when receiving the arrival signal of the dedicated freight car;

[0145] The operating system is also used to control the automatic guided vehicle to lift the shelves containing goods and run them into the subway car of the dedicated freight car.

[0146] Among them, the underground platform cargo distribution area is close to one side of the special freight car in the last section of the subway, and an AGV cart is set up on the other side to transport the existing cargo shelves into the special freight car.

[0147] A cargo distribution center is located on the platform near the last subway car. On the other side is an AGV area for transporting existing cargo onto dedicated freight cars. Routes for the aerial and AGVs are planned, and charging stations are installed in the automated equipment charging area to ensure the AGVs' endurance. Two identical cargo shelves are installed on the platform near the front or rear door of the last train car to reduce transport distance and speed, preventing the shelves from collapsing when being transported by the AGVs.

[0148] Optionally, the stacker can run on two parallel tracks provided inside a dedicated freight carriage;

[0149] The stacker is used to identify and sort goods, and sort them to different fixed shelves according to the destination of different cargo boxes;

[0150] The fixed shelves are used to store sorted goods.

[0151] Among them, after the AGV cart transports the mobile shelf to the designated location in the carriage, the stacker in the carriage sorts the cargo boxes while the train is running, and transports the cargo boxes for the next station on the fixed shelf to the mobile shelf, and transports the cargo boxes on the mobile shelf that are not for the next station to the fixed shelf.

[0152] Optionally, the operating system is also used to control the automatic navigation cart in the compartment to transport the goods to the platform cargo distribution area at the destination when receiving the signal that the fixed shelf has arrived at the destination.

[0153] The platform cargo distribution area and the second smart storage and retrieval cabinet at the destination are the platform cargo distribution area and the smart storage and retrieval cabinet at the same station.

[0154] The operation system is also used to control the transportation of cargo from the aerial cart to the second smart locker.

[0155] An optional automated logistics distribution system for urban rail transit, based on passenger and freight transport, includes ground-level intelligent lockers, overhead transport carts, underground cargo distribution areas, and automated storage within subway cars. The ground-level intelligent lockers are located close to the subway station entrance, serving as temporary storage for goods. They facilitate customer access and transport of goods via the overhead rails. These lockers are connected to the cargo distribution system via EMS overhead carts. To minimize the impact of ground space on the normal operation of urban rail transit and ensure the safety of both pedestrians and goods, an intra-station freight system using overhead carts is employed, transporting cargo containers via a monorail system with one container per vehicle. The platform and concourse tracks are divided into two loops, connected by additional tracks. The concourse loop is also connected to the exits. This facilitates transfers within the station, reduces route conflicts between carts, and shortens travel time. Shelves are installed on the platform near the last subway car, serving as a cargo distribution center. On the other side, an AGV (Automated Guided Vehicle) area is provided for transporting existing cargo containers onto dedicated freight cars. While planning routes for aerial carts and AGVs, charging stations are installed in automated equipment charging areas to ensure the AGVs' endurance. Two racks of the same specifications are placed on the platform at the front or rear door of the last train car to reduce transport distance and speed, preventing the racks from collapsing when being transported by the AGVs. Two stacking cranes and fixed racks are deployed in dedicated freight subway cars. When goods enter the car via the mobile racks, the stacking cranes sort and retrieve goods according to their destinations.

[0156] Optionally, AI technology can be used to identify passenger flow (OD) and dynamically plan off-peak periods for freight transport. When the subway transitions from peak to off-peak periods, flexible marshaling control technology can be applied. When the subway transitions from peak to off-peak, the last car is unmarshaled and replaced with a freight car.

[0157] Optionally, the operations scheduling system monitors the capacity of smart lockers and shelves to balance the flow of goods and people. During peak periods, subway stops can be extended to meet transportation needs.

[0158] Optionally, smart lockers can be installed at subway station entrances. Users and couriers can deposit and withdraw packages by scanning a code. After the corresponding locker door opens, the packaged goods are placed in a container inside the locker. The user closes the door and exits. The top of the smart locker is connected to an overhead track that connects to the subway station. When a cart reaches the top of the locker, cargo can be deposited or withdrawn. An EMS cart enters the subway station and runs along the track. It identifies the container's address based on the barcode on the container and delivers it to a designated distribution center. Upon arrival at the destination distribution center, the EMS cart places the container into the designated rack. Upon arrival, an AGV outside the train car transports the movable rack to a designated location inside the train car. Simultaneously, an AGV inside the train car transports the arriving movable rack to the distribution center. After the AGV transports the mobile rack to the designated location within the train, the stacker crane sorts the boxes while the train is running, moving boxes destined for the next stop from the fixed rack to the mobile rack, and boxes destined for other stops from the mobile rack to the fixed rack. After sorting is complete, upon arrival of the train, the AGV transports the mobile rack to the station's platform distribution center. Boxes arriving at the designated exit platform are transported along the tracks by EMS aerial vehicles to smart lockers outside the station. Upon arrival at the smart locker, arrival information is sent to the courier or recipient. The courier uses this information to retrieve the goods from the smart locker and make final delivery. The recipient must collect their goods within a specified timeframe.
