DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and effect of the present application clearer and more specific, the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. The described embodiments are only possible technical implementations of the present application, not all possible implementations. Based on the embodiments in the present application, those skilled in the art can completely combine the embodiments of the present application to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present application.

[0019] First, the English nouns involved in this application are explained: AGV: Automated Guided Vehicle, used for transporting vehicles; GPS: Global Positioning System, used for positioning; GIS: Geographic Information System, used for geographic data processing.

[0020] In related technologies, such as Figure 1As shown in the figure, the existing subway rectangular wind shaft abandoned space is transformed into a parking lot. The parking lot after the technical transformation is limited and cannot meet more parking needs. The depth of the subway wind shaft is generally 20-30m, and the length and width are basically below 20m. The abandoned space is more scattered and narrow, and the space that can be reasonably used is much smaller than the subway starting working shaft. Moreover, the original function of the wind shaft is ventilation to maintain the air quality in the subway tunnel. After being transformed into a parking lot, vehicle exhaust accumulates, and the air quality cannot meet the standard. Adding an efficient ventilation system will further increase the transformation cost and operating energy consumption. In addition, the wind shaft is also used for firefighting and escape in critical moments. The transformed wind shaft may not be conducive to the approach and operation of fire trucks, increasing the difficulty and time of rescue work.

[0021] It is understandable that many abandoned large-diameter circular working shafts will be left behind during the construction of intercity railway shield tunnels. These working shafts have large space resources. If they can be effectively utilized, they will provide new solutions for urban parking. In order to achieve the rational utilization of limited land, this application transforms the abandoned circular working shafts into underground cylindrical three-dimensional parking garages, which can solve the problem that existing parking facilities are difficult to meet the growing parking needs and meet the gap between supply and demand of parking spaces in densely populated areas in cities.

[0022] The following describes the parking garage reconstruction method and parking garage based on the circular working shaft of the intercity railway shield tunnel embodiment of the present application with reference to the accompanying drawings. In view of the problem that the intercity railway shield tunnel in the above-mentioned related art has an abandoned large-diameter circular working shaft left during the construction process, and the working shaft needs to be backfilled, resulting in high cost and low resource utilization, the present application provides a parking garage reconstruction method based on the circular working shaft of the intercity railway shield tunnel. In this method, by converting the annular structure of the abandoned working shaft into a multi-story three-dimensional parking space, the vertical lifting channel is set according to the depth of the shaft, and the parking spaces are arranged in the annular area, so as to avoid backfilling the working shaft, realize the functional transformation of the infrastructure, and thus reduce the cost and improve the resource utilization. As a result, the technical problem that the intercity railway shield tunnel in the related art has an abandoned large-diameter circular working shaft left during the construction process, and the working shaft needs to be backfilled, resulting in high cost and low resource utilization, is solved.

[0023] The technical solution of the present application is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0024] like Figure 2 , Figure 3 and Figure 4As shown, the embodiment of the present application provides an underground cylindrical three-dimensional parking garage, which is rebuilt according to the parking garage reconstruction method based on the circular working shaft of the intercity railway shield tunnel. The underground cylindrical three-dimensional parking garage includes a working shaft body and a multi-layer annular parking area formed in the working shaft body, and the multi-layer annular parking area includes a first floor ( Figure 1 ) and multiple standard floors located below the first floor ( Figure 2 ); an elevator is installed on the reserved lifting passages on the first floor and multiple standard floors (i.e. Figure 2 The lifting platforms at the entrance a and the exit b in the figure), multiple standard layers are respectively equipped with inner ring rotating platforms (i.e. Figure 2 The middle area of ​​the ring structure between the outer ring and the center of the first floor is respectively equipped with carriers (i.e., AGVs, which are arranged on the first floor and the plurality of standard floors). Figure 2 The inner ring rotating platform is used to drive the vehicle on the target standard floor to rotate, and the carrier is used to move the vehicle between the elevator and the first floor and the standard floor.

[0025] In the present application, when a vehicle enters the entrance of the first floor and needs to park, the carrier on the first floor moves the vehicle to the elevator at the entrance and returns to its position. After the elevator at the entrance drives the vehicle down to the target standard floor, the carrier corresponding to the target standard floor moves the vehicle to the parking space to complete the storage of the vehicle; when the vehicle needs to be retrieved, the inner ring rotating platform drives the vehicle on the target standard floor to rotate so that the vehicle corresponds to the carrier corresponding to the target standard floor and the elevator at the exit. The carrier corresponding to the target standard floor moves the vehicle to the elevator at the exit and returns to its position. The elevator at the exit drives the vehicle to the exit of the first floor to complete the retrieval of the vehicle, so that the driver can drive the vehicle out of the underground parking garage.

[0026] The underground cylindrical three-dimensional parking garage of this application is equipped with a shaft parking garage, underground AGV parking, equipment room, etc., and the garage entrance and exit, pedestrian walkway, necessary management rooms, central landscape, etc. are arranged on the ground. The shaft parking garage and the underground conventional self-propelled parking garage are arranged. The vehicle enters the parking area through the ground garage entrance, and the AGV parks the vehicle in the shaft parking garage area (inside the working shaft). When picking up the vehicle, the AGV places the vehicle in the pick-up area, and the user drives the vehicle out of the parking garage from the exit of the pick-up area. The underground storage and retrieval area is respectively equipped with pedestrian stairs and vertical elevators to connect to the ground to ensure the convenience of storing and retrieving the vehicle. The working shaft of this application includes a transport channel and parking areas respectively arranged on the sides of the transport channel. The parking area is provided with multiple parking plates at intervals in the horizontal direction, and the parking plates are arranged in multiple rows in the vertical direction; parking equipment (i.e., elevators, carriers, and inner ring rotating platforms) are arranged in the vertical direction in the transport channel. The parking equipment integrates the functions of lifting, translation, and 360-degree rotation. The vehicle is moved horizontally by the lifting of the elevator and the transverse movement mechanism installed on the elevator to realize the mechanical parking equipment for storing and retrieving vehicles. The storage and retrieval time is about 80-120 seconds depending on the number of designed floors. The first floor of the ground is equipped with an AGV carrier to complete the translation of the vehicle, without human storage, and intelligent storage and retrieval. Laser navigation travel, with an accuracy error of less than 5 mm, the robot has a load capacity of 2.6 tons, a driving speed of up to 1.5 meters per second, can transport any vehicle, and the ground transportation time is less than 60 seconds.

[0027] Specifically, the inner ring rotating platform is based on the annular space of the working shaft, and annular parking plates are arranged in layers along the circumference of the shaft, and each layer of parking plates is connected by a central vertical lifting channel. The parking plates can be designed as a multi-row three-dimensional structure, and the parking angle can be adjusted through a rotating mechanism to optimize the access path. Therefore, when there are many vehicles in the parking garage, the rotation of the target standard layer is controlled by the inner ring rotating platform, so that the vehicle rotates accordingly, so that the vehicle, the exit elevator and the AGV carrier are in the same straight line, that is, the vehicle is located on the carrier track of the carrier for vehicle transportation.

[0028] Specifically, the first floor (ground floor) is equipped with a central control room, equipment room (for equipment management), entrance a, exit b, and pedestrian walkway, and the standard floor is equipped with pedestrian stairs and vertical elevators. The pedestrian walkway connects the first floor and each underground standard floor through stairs and elevators to ensure convenient access for personnel; the first floor entrance a is integrated with the AGV transporter and license plate recognition equipment to realize the rapid storage of vehicles.

[0029] Specifically, the transporter on the first floor can dock with the garage entrance and vertical machine to complete the transportation of vehicles from the ground to the lifting platform. After the transporter on the standard floor reaches each floor through the elevator, it moves between the parking boards along the preset track and interacts with the parking spaces and the lifting platform, thereby realizing fully automatic transportation and precise parking of vehicles, replacing manual driving and improving storage and retrieval efficiency.

[0030] Specifically, the lifting platform includes an elevator and a track. The lifting platform can carry vehicles and move vertically along the shaft. The bottom of the elevator is integrated with the equipment room at the bottom of the shaft (such as ventilation and power facilities) to ensure stable operation.

[0031] In this application, abandoned underground space is utilized to increase the supply of parking spaces, alleviate parking pressure in the core areas of the city, and avoid backfilling of working shafts. The transformation of abandoned working shafts saves about 30%-50% of the cost compared to building new underground parking lots, thereby reducing costs; the parking space density is increased by 2-3 times through a circular layout + vertical lifting, thereby improving space utilization.

[0032] In one embodiment of the present application, a sensor assembly is installed on the first floor and a plurality of the standard floors, and the sensor assembly is connected to electronic equipment in a central control room on the first floor.

[0033] Specifically, the sensor component integrates parking space monitoring, path planning, and user interaction modules, and manages parking space allocation and transporter task scheduling and user reservations in real time through the cloud platform. The sensor component is connected to the transporter, elevator, and license plate recognition equipment through the Internet of Things to obtain device status and vehicle information in real time.

[0034] In the embodiment of the present application, the principle of vehicle access in the parking garage is as follows: Vehicle entry process: After the vehicle enters the parking garage, an infrared sensor is used to detect whether the vehicle is parked in place. On the rotating platform on the first floor of the parking garage (but the first floor does not rotate because there is no vehicle parked), multiple infrared sensors are set up, located in the four directions of the front, back, left, right and bottom of the vehicle. When the vehicle is parked on the rotating platform, these sensors will detect whether the position of the vehicle meets the preset parking specifications. If it is detected that the vehicle is not parked in a standardized manner, the driver will be guided to correct the parking position through the voice prompt function. If the owner still cannot meet the specifications after multiple adjustments, the system can start the automatic adjustment device, such as slightly pushing or pulling the vehicle through a mechanical structure to move it to a suitable position. At the same time, infrared thermal imaging sensors or cameras are set around the rotating platform to monitor the heat source distribution and personnel activities on the platform in real time. When the vehicle is parked on the rotating platform, the system will use these sensors to detect whether there are people in the car and around the platform, and detect the closed state of the door to ensure that the passengers have left. In the control system of the rotating platform, a safety detection module is set up, which is connected to the above-mentioned personnel detection equipment and vehicle detection sensors. Before the rotating platform starts the rotating operation, the safety detection module will comprehensively analyze the data of all sensors to confirm that there is only one vehicle on the platform and there are no people in the vehicle and around the platform. After detecting that there is no one, the rotating platform rotates into place. The AGV trailer robot has a built-in visual recognition system and a laser rangefinder. The visual recognition system uses a camera to capture the image of the vehicle, and uses an image processing algorithm to identify the vehicle's outline, license plate and other feature information to determine the approximate location of the vehicle; the laser rangefinder emits a laser beam to the vehicle and receives the reflected laser signal. According to parameters such as the propagation time and angle of the laser, the distance and relative position relationship between the vehicle and the carrier are accurately calculated. The AGV trailer robot moves to the bottom of the vehicle according to the planned path through the mechanical structure and retractable tray at its bottom. During the movement, the AGV trailer robot monitors the position relationship with the vehicle in real time, and ensures that it can accurately reach the designated position under the vehicle by adjusting its own speed and direction. When the AGV carrier arrives under the vehicle, its mechanical structure starts to work, lifts the vehicle smoothly and fixes it on the pallet. Then, the robot moves the vehicle to the lift according to the predetermined program. During the handling process, the carrier will constantly monitor the status of the vehicle, such as whether the vehicle is stable and whether it has moved, to ensure that the handling process proceeds smoothly. After the car is stored in the elevator of the lifting mechanism, the AGV carrier returns to its position, and the elevator starts to lift and import the next car at the same time. After reaching the designated standard parking space layer 2 (i.e. the standard layer of the second underground floor), the AGV carrier on the standard parking space layer 2 will run the vehicle to the center and use the AGV carrier to store the vehicle in the parking space, and the parking process is completed. When taking the outer layer car, the inner layer rotating platform needs to rotate, and the AGV carrier passes through the carrier track to take the outer layer car.It can be understood that the function of the first floor is to adjust the position of the vehicle and send it to the standard floor of the underground target floor through the elevator at the entrance. The standard floor rotates through the corresponding inner ring rotating platform, so as to avoid the problem of inconvenience in transportation by the carrier due to a large number of vehicles in the parking garage. The vehicle is rotated around the center of the standard floor into place, that is, the vehicle is located on the carrier track, so that the carrier can move the vehicle to the elevator at the exit, and then rise to the first floor for the vehicle to exit.

[0035] In one embodiment of the present application, the underground cylindrical three-dimensional parking garage further includes an exhaust fan and an air duct, the exhaust fan is connected to the air duct, and the air duct is connected to the shutters on the ground.

[0036] Specifically, ventilation, drainage, electricity, monitoring and fire-fighting equipment are centrally arranged in the equipment rooms on each standard floor on the ground. The ventilation system is connected to the ground blinds through air ducts to form a ventilation network that combines natural and mechanical elements. Electricity and monitoring provide power for AGV transporters, elevators and lighting equipment, and cover monitoring of the entire warehouse.

[0037] It should be noted that in the related art, after the construction of the shield tunnel is completed, the abandoned circular working shaft usually needs to be backfilled, which is time-consuming and labor-intensive, and increases capital investment. At the same time, the problem of parking difficulties in cities is becoming increasingly serious. Traditional parking facilities are limited by land resources and are difficult to meet the growing parking needs. This application makes full use of abandoned circular working shafts and transforms them into underground cylindrical three-dimensional parking garages. Through structural optimization design, the working shafts are transformed to set up three-dimensional parking devices in the working shafts, including multi-layer rotating parking platforms, AGV trailer robots, vertical lifting systems and intelligent scheduling systems, so that the parking garage has high space utilization, high parking efficiency and intelligent management characteristics. The present invention can effectively alleviate the parking pressure in the core areas of the city, realize the intensive use of land resources, and reduce the waste of resources in the backfilling of shield working shafts, with good economic and social benefits.

[0038] The parking garage reconstruction method based on the circular working shaft of the intercity railway shield tunnel described in the preferred embodiment of the present application is as follows: Figure 5 As shown, the parking garage reconstruction method based on the circular working shaft of the intercity railway shield tunnel includes the following steps: In step S101, after the structural evaluation of the shield tunnel working shaft meets the reconstruction standard, the shield tunnel working shaft is reconstructed and planned to obtain a circular parking space layout and a ring beam utilization plan.

[0039] This application is applicable to transforming abandoned circular working shafts into vertical shaft underground parking garages, making rational use of abandoned resources and increasing parking spaces without occupying a large amount of land area. Providing more parking spaces solves the parking problem in local congested spots in the area.

[0040] In a possible implementation, the annular parking layout includes the number of parking floors, and the ring beam utilization scheme includes pipeline layout, floor slab coordinated layout and channel fusion layout. The depth, diameter and ring beam position of the shield tunnel working shaft are obtained; the number of parking floors of the shield tunnel working shaft is determined according to the depth and diameter, and the ring beam is used.

[0041] It should be noted that Figure 4 The blocks on the left and right sides of the working well are the ring beams. Figure 4 The bottom plate in the tunnel has been thickened, and the intercity railway tunnel is located below the bottom plate. It is understandable that when the shaft is dug, the top of the tunnel is empty, with a skylight; the vertical wall and the tunnel must be connected, and the bottom plate is located below the tunnel.

[0042] Specifically, first conduct a structural safety assessment to detect the integrity of the working shaft, including cracks in the shaft wall, water seepage, and the distribution and bearing capacity of the original ring beam. Measure the diameter, depth, and geological conditions of the shaft, and assess whether additional reinforcement is needed (such as grouting, carbon fiber cloth reinforcement). Then conduct space planning and ring beam utilization design. The space function planning is divided into multi-layer circular parking areas, vertical lifting passages, equipment rooms, pedestrian passages and other functional areas according to the depth, diameter and position of the shaft. The ring beam utilization design adopts three layout methods for the original ring beam (construction legacy structure) in the shaft. First, the pipeline layout is to transform the top or surrounding of the ring beam into an equipment pipeline corridor (ventilation / drainage / cable tray), or as a fire monitoring installation location, to reduce additional construction costs; second, the floor slab coordinated layout is to combine the ring beam with the parking floor slab and use the ring beam as the edge support of the parking deck slab (see Figure 3 ), improve structural stability; the channel fusion layout is to open a vertical elevator channel between the ring beams (i.e., a reserved lifting channel), use the ring beam as a fixed anchor point for the lifting track, and shorten the transport path of the transporter.

[0043] In the embodiment of the present application, during the reconstruction of the working shaft of the intercity railway, most of the working shafts have several ring beams inside the shaft, which affects the construction layout of the parking lot. Therefore, the ring beams are transformed in the following three ways, so as to make full use of the original structure and reduce the reconstruction cost without affecting the parking function. Specifically: the space utilization and functional transformation of the ring beam. The ring beam occupies part of the space, and its space can be effectively utilized by designing a reasonable functional layout. Equipment pipeline corridors can be set above or around the ring beam to house the ventilation ducts, drainage systems and power lines of the parking lot. In addition, the space of the ring beam can be used as a maintenance passage or a location for installing monitoring and fire-fighting equipment, thereby facilitating the daily operation of the parking garage; the coordinated design of the ring beam and the parking lot layered structure. The ring beam is used as a component of the parking lot layered structure. The ring beam itself can be used to carry the layered plates or part of the equipment of the parking lot. By combining part of the ring beam with the parking floor, it not only reduces the additional construction cost, but also improves the stability of the overall structure. Combined with the distribution characteristics of the ring beam, the layout of parking spaces and passages is optimized to maximize space utilization; the combined design of the ring beam and the vertical lifting passage. The space of the ring beam can be designed in combination with the structure of the vertical lifting passage. By opening a passage or optimizing the position of the elevator, the obstruction of the ring beam to the vehicle access path can be reduced. At the same time, the ring beam can be used as a fixed support point for the vertical elevator track to improve the overall stability and carrying capacity of the lifting system. This application utilizes GPS positioning technology, GIS technology, etc. to comprehensively apply to the collection, management, query, reservation and navigation services of urban parking spaces, thereby realizing the integration of real-time update, query, reservation and navigation services of parking space resources.

[0044] In step S102, a multi-layered annular parking area is formed in the shield tunnel working shaft according to the annular parking space layout and the ring beam utilization plan, wherein the multi-layered annular parking area includes a first floor and multiple standard floors located below the first floor.

[0045] In a possible implementation, abandoned facilities in the shield tunnel working shaft are dismantled and the shaft wall of the shield tunnel working shaft is reinforced; according to the number of parking floors and the pipeline layout, an equipment pipeline corridor is set on the ring beam in the shield tunnel working shaft, wherein the equipment pipeline corridor is used to accommodate ventilation ducts, drainage systems and power lines; according to the number of parking floors, the coordinated layout of the floor slabs and the fusion layout of the channels, the ring beam and the floor slabs in the shield tunnel working shaft are combined and reinforced, and a lifting channel for the elevator is reserved to form a first floor and multiple standard floors located below the first floor.

[0046] Specifically, the abandoned facilities in the well are removed and the main structure is retained; the original ring beam is mechanically optimized, the well wall and bottom plate are reinforced (such as grouting, adding reinforced concrete layer), the inner wall is sprayed with waterproof coating, and water stop strips are set at key joints to ensure the durability of the underground structure (internal structure reinforcement and waterproof treatment). According to the ring beam design plan, the cable bridge is installed on the outside of the ring beam and the ventilation duct is laid; the gap between the ring beams is used to set up a circular maintenance channel and configure a retractable maintenance platform. Prefabricated reinforced concrete floor slabs are used and fixed by ring beam anchor bolts to form a multi-story parking area, and AGV driving tracks and elevator shafts are reserved on each floor.

[0047] The underground parking garage in this application adopts a cylindrical multi-layer design, which maximizes the parking capacity based on the synergy of the ring layout and the vertical lifting channel. The parking space distribution is mainly in a ring structure, and the vertical space in the center is reserved for vehicle lifting, which optimizes the access path and shortens the access time.

[0048] In a possible implementation, an exhaust fan and an air duct are installed at the bottom of the working shaft of the shield tunnel, and the air duct is connected to the shutters on the ground.

[0049] Specifically, multi-storey parking slabs are set up, a circular layout is adopted to optimize space utilization, and ventilation ducts (combined with bottom-of-pit exhaust fans and ground shutters), drainage pumps and fire sprinkler systems are installed.

[0050] This application reconstructs the abandoned large-diameter circular working shaft of the intercity railway shield tunnel into an underground cylindrical three-dimensional parking garage, making full use of the existing underground space resources, reducing land waste and construction costs, and realizing the functional transformation and upgrading of infrastructure. At the same time, exhaust fans and air ducts are installed at the bottom of the shaft, and the air ducts are connected to the high shutters between the ground facilities to form an effective exhaust system. This design makes full use of the natural ventilation advantages of the shaft, and combined with mechanical ventilation, it can ensure the air quality in the parking garage.

[0051] In step S103, an elevator is installed on the reserved lifting channels of the first floor and multiple standard floors, an inner ring rotating platform is installed on multiple standard floors, and a carrier is deployed on the first floor and multiple standard floors to complete the reconstruction of the underground cylindrical three-dimensional parking garage so that the elevator, the inner ring rotating platform and the carrier can store or retrieve vehicles.

[0052] In a possible implementation, the ring beam in the working shaft of the shield tunnel is used as a fixed anchor point, and a lifting track is installed on the reserved lifting passages of the first floor and multiple standard floors; and an elevator is installed on the lifting track.

[0053] Specifically, an elevator pit is installed at the bottom of the well, a lifting platform is set up at the wellhead, and vertical guide rails and elevators are installed to ensure lifting accuracy and stability.

[0054] In a possible implementation, a corresponding inner ring rotating platform is installed on each of the standard layers, so that each of the standard layers can be independently driven to rotate.

[0055] Specifically, a multi-storey parking plate (arranged in a ring) and a rotating platform on the first floor (the first floor does not rotate) are installed, equipped with infrared sensors and vehicle adjustment devices.

[0056] In a possible implementation, corresponding travel tracks and automatic charging stations are respectively installed on the first floor and each of the standard floors; carriers are respectively deployed on the travel tracks corresponding to the first floor and each of the standard floors, the initial position of the carrier is located at the center of the inner side of the inner ring rotating platform, and the carrier is connected to the automatic charging station.

[0057] Specifically, AGV carrier tracks are laid in each parking area and automatic charging stations are set up.

[0058] The AGV carrier and lift of this application are used for vehicle storage and retrieval. The AGV (automatic guided vehicle) carrier is used to achieve efficient lifting and precise storage and retrieval operations of vehicles. The AGV carrier based on autonomous navigation technology can flexibly move in the vertical and horizontal channels of the parking garage, and accurately dispatch vehicles from the ground entrance to the parking spaces on each floor, thereby reducing the complexity of traditional mechanical lifting equipment and significantly reducing the failure rate. At the same time, the AGV carrier is equipped with a real-time path planning algorithm, which can dynamically adjust the operation trajectory, avoid path conflicts, and improve the overall storage and retrieval efficiency. In terms of energy, the robot system is equipped with an automatic charging function to support long-term continuous operation. In addition, combined with the Internet of Things technology, it can be seamlessly connected with the parking management system to further realize unmanned and intelligent operation.

[0059] In one possible implementation, a smart cloud platform is deployed that integrates license plate recognition, parking space allocation, and path planning algorithms, and installs cameras and thermal imaging sensors to monitor the status of the garage in real time.

[0060] This application integrates a highly intelligent parking management system, combined with the Internet of Things technology, to achieve dynamic allocation of parking spaces, license plate recognition, automatic billing, and remote reservation functions. The parking management system monitors the use of parking spaces in real time and dynamically adjusts resource allocation, reducing vacancy rates and queue times. At the same time, the system can collect data such as vehicle in and out flow and parking duration to provide a basis for optimization strategies for parking garage operators. Users can remotely reserve parking spaces through mobile phone applications and receive intelligent navigation and voice guidance when entering the parking garage, greatly improving the convenience of the parking experience.

[0061] In the embodiment of the present application, the specific process of transforming the working shaft into a parking lot is as follows: first, the internal structure of the original working shaft is dismantled, and then the ring beam in the shaft is structurally optimized and transformed, and a vertical elevator is set as the core equipment for vehicle access. At the same time, the floor of each parking lot is installed on the basis of the ring beam to form a multi-layer circular parking area. After the vehicle enters the parking lot, the AGV parking robot and the vertical elevator are coordinated to realize intelligent access to the vehicle, providing efficient and convenient unmanned parking services. The entire system is monitored and managed by the smart cloud platform throughout the process, covering vehicle access scheduling, parking space allocation, and fee settlement functions, fully enabling the efficient operation of smart parking lots. This design not only improves parking efficiency, but also optimizes resource utilization, providing an intelligent solution for modern urban parking.

[0062] Compared with the related art of transforming the abandoned space of the subway rectangular air shaft into a parking lot, this application Figure 6 and Figure 7 If an abandoned circular working shaft is used to transform an underground parking lot, taking a diameter of 36m and a depth of 50m as an example, a 36m diameter working shaft can be transformed into two 18m diameter circular parking lots, with a hoist in the middle to transport vehicles to the designated parking space floor. A working shaft of this size can provide 300 parking spaces. There is a huge advantage in the number of parking spaces. And the transformation itself conforms to the environmental protection idea of ​​resource reuse. In this way, waste resources can be reasonably utilized and parking spaces can be increased without occupying a large amount of land area, providing more parking spaces.
