[0002] With the high-quality development of the economy and people's demands for high-quality life, transportation, urban governance, environmental protection and low carbon, higher and higher requirements are put forward for urban transportation.

[0003] However, for transportation such as light rail, straddle monorail, and suspended sky train, there is only a single track and a single passenger transportation mode on each line. The urban low-altitude transportation resources are not fully utilized. There is a lack of an upper and lower composite track to improve the utilization efficiency of urban low-altitude transportation resources, and there is a lack of a high-speed intelligent logistics vehicle and its transportation system that share the track with passenger vehicles, so as to realize the alternating passage and scientific integration of high-speed passenger vehicles and high-speed logistics vehicles during non-traffic peaks. Summary of the Invention

[0004] The purpose of the present invention is to provide, in view of the above existing problems and deficiencies, a high-speed intelligent logistics system based on a composite special-shaped flange track, especially a high-speed intelligent logistics vehicle with a four-cantilever bogie on the lower flange of a composite special-shaped flange track based on an H-structured base beam (1), which can run on the same track as a high-speed high-end intelligent passenger vehicle. The urban low-altitude resources are fully utilized. During traffic peaks, the upper and lower composite tracks operate the upper flange special-shaped L-track vehicle (3V) and the lower flange high-speed high-end intelligent bus at the same time. During non-traffic peaks, the logistics vehicle and the bus share the track to maximize the efficiency of traffic resources. The present invention provides a solution for a high-speed intelligent logistics system based on a composite special-shaped flange track. Overview of the Invention

The function of the steering mechanism (8A) is that when the vehicle passes through a curve, under the action of centrifugal force, the cantilever frame (86) mounted on the top of the carriage will twist with the suspension column (81) as the axis, and the air spring (85) and the damper (8E) will also twist simultaneously. One of the springs (8C) at both ends of the lever (8D) of the steering mechanism (8A) is compressed and the other is stretched. When the vehicle passes through the curve, under the combined action of the springs (8C) at both ends, the air spring (85), and the damper (8E), the cantilever frame (86) smoothly returns to its original position, as Figure 4 shown.

[0011] The present invention provides a bogie (6G), which comprises a load-bearing base frame and a cantilever steering mechanism (8). The cantilever steering mechanism (8) is installed below the load-bearing base frame; the load-bearing base frame is a rectangular frame structure, including side longitudinal beams (6H), side cross beams (6J), middle longitudinal beams (6K), cantilever cross beams (6L), and middle cross beams (6M). On a horizontal plane, two side longitudinal beams (6H) and two side cross beams (6J) are connected end to end to form a rectangular frame. Inside the rectangular frame, there are 0 to 3 or more middle longitudinal beams (6K) parallel to the side longitudinal beams (6H) and evenly distributed and vertically installed on the side cross beams (6J); inside the rectangular frame, there are 1 to 3 or more cantilever cross beams (6L) and 0 to 3 or more middle cross beams (6M) parallel to the side cross beams (6J) and arranged at equal intervals, and are cross-vertically installed on the side longitudinal beams (6H) and the middle longitudinal beams (6K); professionals can select the quantities of the middle longitudinal beams (6K), the cantilever cross beams (6L), and the middle cross beams (6M) according to needs; as Figure 3 shown.

[0045] The present invention provides an operation method for a high-speed intelligent logistics system based on a composite special-shaped flange track:

[0046] 1) For inter-city logistics, the high-speed intelligent logistics vehicle performs palletized overall packaging or standardized box-type quick loading and unloading operations at the station. The station transmits all information such as the quantity of goods newly loaded on each high-speed intelligent logistics vehicle, the name of the goods, the sender information, the recipient information, the vehicle number of the logistics vehicle, the destination station, and whether there are empty cargo spaces on the vehicle to the in-vehicle Internet of Things corresponding to each vehicle, and also transmits it to the logistics central system through the station management system;

[0047] According to the situation of the station and transportation requirements, a train is formed by 1 to 15 or more vehicles, and each station is provided with spare empty vehicles. A train is dispatched from the departure station on the composite special-shaped flange track system under the management and control of the logistics central system, the station management control system, the safe operation system, and the unmanned intelligent driving system, etc.

[0048] 2) The equipment status, real-time position, running speed, etc. of the high-speed intelligent logistics vehicle running on the composite special-shaped flange track system are sent to the logistics central system and the Internet of Things of the 3 to 5 vehicles before and after in real time through the vehicle Internet of Things to achieve safe coordinated operation of the 3 to 5 vehicles before and after. For example, if a vehicle needs to make an emergency brake due to reasons, the 3 to 5 vehicles behind will synchronously decelerate and drive, and sequentially transmit to the subsequent vehicles to achieve safe coordinated operation;

[0049] The number of empty cargo spaces in the vehicle and the quantity information of the goods arriving at the destination station are uploaded to the logistics central system by the vehicle Internet of Things. The logistics central system sends this information to the destination station management system, and the destination station intelligent management system (verified and supervised by staff) can formulate a unloading plan and a loading plan according to the information, which will be implemented by the station intelligent operation system.

[0050] 3) After the high-speed intelligent logistics vehicle arrives at the destination station, the station intelligent operating system accurately implements fast unloading and loading of goods according to the unloading plan and loading plan. When the fast unloading is completed, the station intelligent operating system transmits all the information related to the goods of the vehicle's Internet of Things to the station intelligent management system, and the station intelligent management system simultaneously feeds back and uploads the information of the arrival of the goods to the logistics central system; after the new loading is completed, the station intelligent operating system transmits the information of the newly loaded goods of the vehicle to the vehicle Internet of Things through the station intelligent management system, and the station intelligent management system simultaneously uploads the information of the newly loaded goods to the logistics central system; the logistics central system transmits the information of the newly loaded goods at this station to the destination station where it is to arrive, and circulates in turn.

[0051] 4) The intracity logistics supporting services complete the last mile well.

[0052] The high-speed intelligent logistics vehicle is loaded by the logistics sorting center in the suburban area of the city according to the fast loading and unloading operation mode of express parcels or other logistics parcels of residents or units within a radius of 2 - 5 kilometers (or other range division methods) around each destination station in the city, as a pallet whole package or a standardized express box.

[0053] When loading at the suburban logistics sorting center, the sorting center management system sends information such as the names of goods, quantities, recipient information, destination stations, and the numbers of the pallet whole package or standardized express box of the express parcels or other logistics parcels loaded in the pallet whole package or standardized express box to the on-board Internet of Things of this vehicle, and simultaneously sends it to the logistics central system. The logistics central system sends the information to the corresponding station management system in advance.

[0054] During non-peak traffic hours in the city, the high-speed intelligent logistics vehicle runs on the same track at intervals with buses. After arriving at the destination station, according to the instructions of the station management system, the station automatic loading and unloading equipment unloads the pallet whole package or standardized express box arriving at this station and obtains its information. The station automatic loading and unloading equipment loads the goods onto a driverless (or courier) special vehicle, transmits the information of the pallet whole package or standardized express box to the driverless (or courier) intelligent special vehicle, and the station automatic loading and unloading equipment simultaneously obtains the number of the driverless (or courier) intelligent special vehicle and the number of the courier in charge.

[0055] The station automatic loading and unloading equipment transmits the number of the driverless (or courier) intelligent special vehicle, the number of the courier in charge, and the information of the pallet whole package or standardized express box to the station management system, and the station management system uploads the information to the logistics central system; the driverless (or courier) intelligent special vehicle delivers the goods in the pallet whole package or standardized express box to each user according to the information.

[0056] 5) High-speed intelligent logistics vehicles operating in the city use the entire track for high-speed passenger vehicles during peak traffic hours. During non-peak traffic hours, the high-speed intelligent logistics vehicles will alternate with high-speed passenger buses, maximizing the efficiency of traffic resources, minimizing the long-distance transportation of logistics vehicles across the city and their occupation of urban traffic rights, and the driverless (or courier) intelligent special vehicles provide good supporting services for the last mile.

[0057] The above numbers are only for the convenience of narration and do not represent the actual order of operation. Each of the above numbers can be regarded as an operating unit of the high-speed intelligent logistics system. During operation, the order of the operating units can be adjusted according to the actual situation, and even the operating units can be increased or decreased. Parts not detailed in the present invention can all adopt existing technologies.

[0058] The advantages of the present invention are:

[0059] 1. The high-speed intelligent logistics vehicles in the city share the track with passenger buses during non-peak traffic hours, maximizing the efficiency of traffic resources, reducing the long-distance transportation of logistics vehicles across the city and their occupation of urban traffic rights, and the driverless (or courier) intelligent special vehicles provide good supporting services for the last mile.

[0060] 2. Intelligent operation is efficient and stable. Advanced operation management control systems, unmanned intelligent driving, in-vehicle Internet of Things, etc. enable digital and precise management of intelligent logistics, with high operation efficiency and fast speed. The high-speed intelligent logistics vehicle with a four-cantilever bogie has a maximum sway angle of about 1°, solving the technical problem of the 4° - 15° sway of the single-cantilever bogie vehicle, and running more smoothly at a speed of 120 km / h.

[0061] 3. Intelligent safety guarantee. The track and vehicle structure that will never derail; the vehicle Internet of Things enables the first 3 - 5 vehicles in the front and back to maintain synchronous and safe collaborative operation; the intelligent safety guidance system automatically adjusts the distance between the safety guidance and the track from 0 to 30 mm according to the vehicle operation state, lateral wind force, turning centrifugal force, deviation amount, etc., precisely controlling the magnitude of the auxiliary guiding force and the magnitude of the balance and stability force, minimizing the running resistance to the greatest extent, and multiple hardware and software guarantees ensure the high-speed and safe operation of the vehicle.

[0062] 4. Low-carbon, environmentally friendly and green operation. The high-speed intelligent logistics vehicle has low noise, energy-saving and environmental protection, and the new energy system includes photovoltaic power generation, vehicle braking power generation system, hydrogen power system, etc., enabling the high-speed intelligent logistics vehicle to achieve environmentally friendly and low-carbon operation.

[0063] 5. Advanced track system. The composite special-shaped flange track system of the present invention combines the upper and lower composite H-structured base beams with the special-shaped flange tracks, enhancing and improving the comprehensive structural strength, flexural and torsional stiffness, etc. It makes full use of the urban low-altitude traffic resources. Compared with two single track beams with the same function, it has optimized structure, lighter total weight, material and energy savings, and high comprehensive cost performance; the minimum turning radius is 20 meters, and the climbing ability reaches 100‰. It can be installed on the green belts of urban roads, on the slopes or median strips of highways, in mountain tunnels, or in underground tunnels; it has strong route selection adaptability, less land occupation, less demolition, and low comprehensive cost.

[0166] The present invention provides an operation method for a high-speed intelligent logistics system based on a composite special-shaped flange track:

[0167] 1) For inter-city logistics, the high-speed intelligent logistics vehicle implements palletized overall packaging or standardized box-type quick loading and unloading operations at the station. The station transmits all information such as the quantity of goods newly loaded on each high-speed intelligent logistics vehicle, the name of the goods, the sender information, the recipient information, the vehicle number of the logistics vehicle, the destination station, and whether there are empty cargo spaces on the vehicle to the in-vehicle Internet of Things of each vehicle, and at the same time, it is also transmitted to the logistics central system through the station management system;

[0168] According to the situation of the station and transportation requirements, a train can be composed of 1 to 15 vehicles or more, and each station is equipped with spare empty vehicles. A train is dispatched from the departure station on the composite special-shaped flange track system under the management and control of the logistics central system, the station management control system, the safe operation system, and the unmanned intelligent driving system, etc.;

[0169] 2) The equipment status, real-time position, running speed, etc. of the high-speed intelligent logistics vehicle running on the composite special-shaped flange track system are sent to the logistics central system and the Internet of Things of the 3 to 5 vehicles before and after through the vehicle Internet of Things in real time to achieve safe coordinated operation of the 3 to 5 vehicles before and after. For example, if a vehicle needs to brake urgently due to reasons, the 3 to 5 vehicles behind will synchronously decelerate and drive, and transmit to the subsequent vehicles in turn to achieve safe coordinated operation;

[0170] The number of empty cargo spaces in the vehicle and the quantity information of the goods arriving at the destination station are uploaded to the logistics central system by the vehicle Internet of Things. The logistics central system sends this information to the destination station management system. The staff of the destination station intelligent management system can verify and supervise and formulate a unloading plan and a loading plan according to the information, which will be implemented by the station intelligent operation system.

[0171] 3) After the high-speed intelligent logistics vehicle arrives at the destination station, the station intelligent operating system accurately implements fast unloading and loading of goods according to the unloading plan and loading plan. When the fast unloading is completed, the station intelligent operating system transmits all the information related to the goods of the vehicle's Internet of Things to the station intelligent management system, and the station intelligent management system simultaneously feeds back and uploads the information of the arrival of the goods to the logistics central system; after the new loading is completed, the station intelligent operating system transmits the information of the newly loaded goods of the vehicle to the vehicle Internet of Things through the station intelligent management system, and the station intelligent management system simultaneously uploads the information of the newly loaded goods to the logistics central system; the logistics central system transmits the information of the newly loaded goods at this station to the destination station where it is to arrive, and runs in a loop in turn.

[0172] 4) The in-city logistics supporting service completes the last mile well.

[0173] The high-speed intelligent logistics vehicle is loaded at the logistics sorting center in the suburban area of the city according to the express parcels or other logistics parcels of residents or units within a radius range of 2 - 5 kilometers or other range division methods around each destination station in the city, in the fast loading and unloading operation mode of a pallet whole package or a standardized express box.

[0174] When loading at the suburban logistics sorting center, the sorting center management system sends information such as the names of goods, quantities, recipient information, destination stations, and the numbers of the pallet whole package or standardized express box of the express parcels or other logistics parcels loaded in the pallet whole package or standardized express box to the on-board Internet of Things of this vehicle, and simultaneously sends it to the logistics central system. The logistics central system sends the information to the corresponding station management system in advance.

[0175] During non-traffic peak hours in the city, the high-speed intelligent logistics vehicle runs on the same track at intervals with buses. After arriving at the destination station, according to the instructions of the station management system, the station automatic loading and unloading equipment unloads the pallet whole package or standardized express box arriving at this station and obtains its information. The station automatic loading and unloading equipment loads the goods onto a driverless or courier's special vehicle, and transmits the information of the pallet whole package or standardized express box to the driverless or courier's intelligent special vehicle. The station automatic loading and unloading equipment simultaneously obtains the number of the driverless or courier's intelligent special vehicle and the number information of the responsible courier.

[0176] The station automatic loading and unloading equipment transmits the number of the driverless or courier's intelligent special vehicle, the number information of the responsible courier, and the information of the pallet whole package or standardized express box to the station management system, and the station management system uploads the information to the logistics central system; the driverless or courier's intelligent special vehicle delivers the goods in the pallet whole package or standardized express box to each user according to the information.

[0177] 5) High-speed intelligent logistics vehicles operating in the city use the entire track for high-speed passenger vehicles during peak traffic hours. During non-peak traffic hours, high-speed intelligent logistics vehicles will alternate with high-speed passenger vehicles, achieving the maximization of traffic resource benefits, minimizing the long-distance transportation of logistics vehicles across the city and their occupation of urban traffic rights. Unmanned or intelligent special delivery vehicles provide good supporting services for the last mile.
