[0027] To make the objectives, technical solutions and effects of the present application clearer and more definite, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying 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 efforts, and these embodiments are also within the protection scope of the present application.

[0028] First, the English terms involved in the present application are explained:

[0029] AGV: Automated Guided Vehicle, used for transporting vehicles;

[0030] GPS: Global Positioning System, used for positioning;

[0031] GIS: Geographic Information System, used for processing geographic data.

[0032] In related technologies, such as Figure 1 As shown, the scale of the existing parking lot after the transformation of the abandoned space of the rectangular ventilation shaft of the subway is limited and cannot meet the relatively large parking demand. The subway ventilation shaft is provided with a parking board 2, a ceiling 3, a pull rope 5 and an inlet / outlet 7. The depth of the subway ventilation shaft is generally 20 - 30m, and the length and width are basically less than 20m. The abandoned space is more scattered and narrow, and the space that can be reasonably used is much smaller than that of the subway starting working shaft. Moreover, the original function of the ventilation shaft is to ventilate and maintain the air quality in the subway tunnel. After being transformed into a parking lot, vehicle exhaust accumulates and the air quality fails to meet the standards. Installing an efficient ventilation system will further increase the transformation cost and operating energy consumption. And in case of emergency, the ventilation shaft is also used for fire fighting and escape. The transformed ventilation shaft may be unfavorable for the approach and operation of fire trucks, increasing the difficulty and time of rescue work.

[0033] It can be understood that during the construction of the intercity railway shield tunnel, many abandoned large-diameter circular working shafts will be left. These working shafts have large space resources. If they can be effectively utilized, they will provide a new solution for urban parking. In order to realize the rational utilization of limited land plots, this application transforms the abandoned circular working shaft into an underground cylindrical multi-story parking garage, which can solve the problem that the existing parking facilities are difficult to meet the growing parking demand and meet the supply-demand gap of parking spaces in densely populated urban areas.

[0034] Next, the method for reconstructing a parking garage based on the circular working shaft of the intercity railway shield tunnel and the parking garage in the embodiments of this application will be described with reference to the accompanying drawings. Aiming at the problem in the related technologies mentioned above that during the construction of the intercity railway shield tunnel, the abandoned large-diameter circular working shaft needs to be backfilled, resulting in high costs and low resource utilization rates, this application provides a method for reconstructing a parking garage based on the circular working shaft of the intercity railway shield tunnel. In this method, by transforming the annular structure of the abandoned working shaft into a multi-story three-dimensional parking space, using the depth of the shaft to set up a vertical lifting channel, and arranging parking spaces in the annular area, the backfilling of the working shaft is avoided, the functional transformation of the infrastructure is realized, and thus the cost is reduced and the resource utilization rate is improved. Thereby, the technical problem in the related technologies that during the construction of the intercity railway shield tunnel, the abandoned large-diameter circular working shaft needs to be backfilled, resulting in high costs and low resource utilization rates is solved.

[0035] The technical solution of the present application will be described in detail below with specific embodiments. These several specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0036] As Figure 2 , Figure 3 and Figure 4 shown, an underground cylindrical multi-story parking garage is provided in an embodiment of the present application. The underground cylindrical multi-story parking garage is rebuilt according to a parking garage rebuilding method based on a circular working shaft of an intercity railway shield tunnel. The underground cylindrical multi-story parking garage includes a working shaft body and a multi-story circular parking area formed within the working shaft body. The multi-story circular parking area includes a first floor ( Figure 1 ) and a plurality of standard floors ( Figure 2 ) located below the first floor; elevators are installed on the reserved lifting channels of the first floor and the plurality of standard floors (i.e., the lifting platforms at entrance a and exit b in Figure 2 ), inner ring rotating platforms are respectively installed on the plurality of standard floors (i.e., the circular structure in the middle area between the outer ring and the center in Figure 2 ), and transporters (i.e., AGVs, arranged at the center of Figure 2 ) are respectively deployed on the first floor and the plurality of standard floors. The elevator is used to lift the vehicle between the first floor and the target standard floor, the inner ring rotating platform is used to drive the vehicle on the target standard floor to rotate, and the transporter is used to move the vehicle between the elevator, the first floor and the standard floors.

[0037] In the present application, when a vehicle drives into the entrance on the first floor and needs to park, the transporter on the first floor moves the vehicle to the elevator at the entrance and returns to its original position. After the elevator at the entrance drives the vehicle down to the target standard floor, the transporter corresponding to the target standard floor moves the vehicle to the parking space, completing 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 transporter corresponding to the target standard floor and the elevator at the exit. The transporter corresponding to the target standard floor moves the vehicle to the elevator at the exit and returns to its original position. The elevator at the exit drives the vehicle up to the exit on the first floor, completing the retrieval of the vehicle, enabling the driver to drive the vehicle away from the underground parking garage.

[0038] The underground cylindrical three-dimensional parking garage of the present application is provided with a shaft-type parking garage, underground AGV parking, equipment rooms, etc. The garage entrance, pedestrian walkway, and necessary management rooms, central landscape, etc. are arranged on the ground. The shaft-type parking garage and the underground conventional self-propelled parking garage are arranged. Vehicles enter the parking area through the ground garage entrance, and the AGV parks the vehicle in the shaft-type 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 pick-up area through the exit. Pedestrian stairways and vertical elevators are respectively arranged in the underground vehicle storage and retrieval areas to connect with the ground, ensuring the convenience of vehicle storage and retrieval. The working shaft body of the present application includes a transportation passage and parking areas respectively arranged on the sides of the transportation passage. A plurality of parking boards are arranged at intervals along the horizontal direction in the parking area, and multiple rows are arranged along the vertical direction of the parking boards; a parking device (i.e., a lift, a transporter, and an inner ring rotating platform) is movably arranged along the vertical direction in the transportation passage. This parking device integrates the functions of lifting, translation, and 360-degree rotation. The vehicle is translated through the lifting of the hoist and the transverse movement mechanism installed on the hoist, realizing a mechanical parking device for storing and retrieving vehicles. The storage and retrieval time of the vehicle is about 80 - 120 seconds according to different designed floors. One set of AGV transporter is equipped on the ground floor to complete the translation of the vehicle, realizing unmanned warehousing and intelligent storage and retrieval. It travels by laser navigation, and the precision error is less than 5 millimeters. The load capacity of the robot is 2.6 tons, and the traveling speed can reach 1.5 meters per second. It can carry any vehicle, and the ground handling time is less than 60 seconds.

[0039] Specifically, based on the annular space of the working shaft, the inner ring rotating platform is arranged with annular parking boards in layers along the circumferential direction of the shaft. Each layer of parking board is connected through a central vertical lifting passage. The parking board can be designed as a multi-row three-dimensional structure, and the angle of the parking space is adjusted through a rotation mechanism to optimize the storage and retrieval path. Thus, when there are many vehicles in the parking garage, the rotation of the target standard floor is controlled through the inner ring rotating platform, so that the vehicle rotates correspondingly, making the vehicle, the exit lift, and the AGV transporter in a straight line, that is, the vehicle is located on the transporter track of the transporter for vehicle handling.

[0040] Specifically, a central control room, an equipment room (for equipment management), entrance a, exit b, and a pedestrian walkway are arranged on the first floor (ground floor). Pedestrian stairways and vertical elevators are arranged on the standard floors. The pedestrian walkway is connected to the first floor and each underground standard floor through stairways and elevators, ensuring the convenient entry and exit of personnel; the entrance a on the first floor is integrated with the AGV transporter and license plate recognition equipment to realize the rapid entry of vehicles.

[0041] Specifically, the transporter on the first floor can be docked with the garage entrance and the vertical machine to complete the ground handling of the vehicle to the lifting platform. After the transporter on the standard floor reaches each floor through the lift, it moves between the parking boards along the preset track and interacts with the parking space and the lifting platform, thus realizing the full-automatic handling and precise parking of the vehicle, replacing manual driving and improving the storage and retrieval efficiency.

[0042] Specifically, the lifting platform includes a lift and tracks. The lifting platform can carry vehicles and move vertically along the shaft. The bottom of the lift is integrated with the equipment rooms at the bottom of the shaft (such as ventilation and power facilities) to ensure stable operation.

[0043] In this application, the use of abandoned underground space increases the supply of parking spaces, relieves the parking pressure in the core urban area, and avoids backfilling the working wells. Transforming the abandoned working wells saves about 30%-50% of the cost compared with building a new underground parking lot, thus reducing the cost; the use of a circular layout + vertical lifting increases the parking space density by 2-3 times, improving the space utilization rate.

[0044] In an embodiment of this application, sensor components are installed on the first floor and multiple standard floors, and the sensor components are connected to the electronic devices in the central control room on the first floor.

[0045] Specifically, the sensor components integrate parking space monitoring, path planning, and user interaction modules. Through the cloud platform, the parking space allocation and the task scheduling of the transporter for user reservations are managed in real time. The sensor components are connected to the transporter, the lift, and the license plate recognition device through the Internet of Things to obtain the device status and vehicle information in real time.

[0046] In the embodiment of this application, the principle of vehicle access in the parking garage is as follows:

[0047] Vehicle entry process: After the vehicle enters the parking garage, infrared sensors are 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 are no parked vehicles), multiple infrared sensors are set, located in the four directions of the front, rear, left, and right of the vehicle, as well as under 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 properly, the driver will be guided to correct the parking position through the voice prompt function. If the owner still cannot meet the specification requirements after multiple adjustments, the system can activate 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. After the vehicle is parked on the rotating platform, the system will detect whether there are people inside the vehicle and around the platform through these sensors, and detect the door closing state to ensure that the passengers have left. In the control system of the rotating platform, a safety detection module is set, which is connected to the above-mentioned personnel detection equipment and vehicle detection sensors. Before the rotating platform starts the rotation 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 inside the vehicle and around the platform. After detecting no one, after the rotating platform rotates in place, the AGV trailer robot is equipped with a visual recognition system and a laser rangefinder. The visual recognition system takes pictures of the vehicle through a camera, and uses image processing algorithms to identify the contour, license plate and other characteristic information of the vehicle to determine the approximate position of the vehicle; the laser rangefinder emits a laser beam towards the vehicle and receives the reflected laser signal, and accurately calculates the distance and relative position relationship between the vehicle and the transporter according to parameters such as the propagation time and angle of the laser. The AGV trailer robot can move to the bottom of the vehicle through the mechanical structure and telescopic 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 transporter reaches under the vehicle, its mechanical structure starts to work, and the vehicle is smoothly lifted and fixed on the tray. Then, the robot transports the vehicle to the elevator according to the predetermined program. During the transportation process, the transporter will continuously monitor the state of the vehicle, such as whether the vehicle is stable and whether there is displacement, to ensure the smooth progress of the transportation process. After the elevator of the lifting mechanism reaches the designated position for storing the car, the AGV transporter returns to its original position, and the elevator starts to lift while the next car enters and exits the import. After reaching the designated standard parking layer 2 (i.e., the standard layer on the second basement floor), the AGV transporter on the standard parking layer 2 runs the vehicle to the center and uses the AGV transporter to store the vehicle in the parking space, and the vehicle storage process is completed. When retrieving the outer-layer vehicle, the inner-layer rotating platform needs to rotate, and the AGV transporter retrieves the outer-layer vehicle through the transporter track.It can be understood that the function of the first floor is to align the position of the vehicle and send it into 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 inconvenient handling by the transporter due to a large number of vehicles in the parking garage, and make the vehicle rotate to the position around the center of the standard floor, that is, the vehicle is located on the transporter track, so that the transporter can move the vehicle to the elevator at the exit and then rise to the first floor for the vehicle to drive out.

[0048] In an 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 louvers on the ground.

[0049] Specifically, the equipment rooms on each standard floor on the ground are centrally arranged with ventilation, drainage, power, monitoring and fire-fighting equipment. The ventilation system is connected to the ground louvers through air ducts to form a ventilation network combining nature and machinery; power and monitoring supply power to AGV transporters, elevators and lighting equipment, and cover the whole garage for monitoring.

[0050] It should be noted that in the related art, after the shield tunnel construction is completed, the abandoned circular working shaft usually needs to be backfilled, which is time-consuming and laborious, and increases the capital investment. At the same time, the problem of urban parking difficulty is becoming increasingly serious. Traditional parking facilities are restricted by land resources and it is difficult to meet the growing parking demand. Through the full utilization of the abandoned circular working shaft, the present application transforms it into an underground cylindrical three-dimensional parking garage. Through the optimized design of the structure, a three-dimensional parking device is arranged in the working shaft, including multi-layer rotating parking platforms, AGV trailer robots, vertical lifting systems and intelligent dispatching systems, so that the parking garage has the characteristics of high space utilization rate, high parking efficiency and intelligent management. The present invention can effectively relieve the parking pressure in the core area of the city, realize the intensive utilization of land resources, and at the same time reduce the waste of resources for backfilling the shield working shaft, and has good economic and social benefits.

[0051] The method for reconstructing a parking garage based on a circular working shaft of an intercity railway shield tunnel described in the preferred embodiment of the present application, as Figure 5 shown, the method for reconstructing a parking garage based on a circular working shaft of an intercity railway shield tunnel includes the following steps:

[0052] In step S101, after the structural evaluation of the shield tunnel working shaft meets the transformation standard, a transformation plan is made for the shield tunnel working shaft to obtain an annular parking space layout and a ring beam utilization plan.

[0053] The present application is applicable to transforming an abandoned circular working shaft into a shaft-type underground three-dimensional parking garage, reasonably utilizing abandoned resources and increasing parking berths without occupying a large amount of land area. Provide more parking spaces to solve the parking problem at local congestion points in the area.

[0054] In a possible implementation, the circular parking space layout includes the number of parking levels, and the utilization plan of the ring beam includes pipeline layout, floor slab collaborative layout, and passage integration layout. Obtain the well depth, diameter, and ring beam position of the shield tunnel working shaft; determine the number of parking levels of the shield tunnel working shaft according to the well depth and the diameter, and determine the pipeline layout, floor slab collaborative layout, and passage integration layout of the shield tunnel working shaft according to the ring beam position.

[0055] It should be noted that Figure 4 The square blocks on the left and right sides in the working shaft of Figure 4 The floor slab in

[0056] Specifically, first, conduct a structural safety assessment to detect the integrity of the working shaft, including well wall cracks, water seepage conditions, and the distribution and bearing capacity of the original ring beam, measure the diameter, depth, and geological conditions of the well, and evaluate whether additional reinforcement (such as grouting, carbon fiber cloth reinforcement) is required. Then, carry out space planning and ring beam utilization design. The space function planning is divided into functional areas such as multi-layer circular parking areas, vertical lifting passages, equipment rooms, and pedestrian passages according to the well depth, diameter, and ring beam position. The ring beam utilization design adopts three layout methods for the original ring beam (construction legacy structure) in the well. First, the pipeline layout is to transform the area above or around the ring beam into an equipment pipeline corridor (ventilation / drainage / cable tray), or as a fire monitoring installation position, reducing additional construction costs; second, the floor slab collaborative layout is to combine the ring beam with the parking floor slab design, using the ring beam as the edge support of the parking floor slab (see Figure 3 ), improving the structural stability; the passage integration layout is to open a vertical elevator passage (i.e., reserve a lifting passage) between the ring beams, using the ring beam as the fixed anchor point of the lifting track, shortening the handling path of the transporter.

[0057] In the embodiments of the present application, during the renovation of the working shafts of the intercity railway, most of the working shafts have several ring beams inside the shafts, which affect the construction layout of the parking lot. Therefore, the following three renovations are carried out on the ring beams, so as to make full use of the original structure and reduce the renovation cost without affecting the parking function. Specifically: the utilization and functional transformation of the ring beam space. The ring beam occupies part of the space, and its space can be effectively utilized by designing a reasonable functional layout. An equipment pipeline corridor can be set above or around the ring beam to place 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, thus facilitating the daily operation of the parking garage; the collaborative design of the ring beam and the layered structure of the parking lot. The ring beam is used as a component of the layered structure of the parking lot. The ring beam itself can be used to carry the layered slabs or some equipment of the parking lot. By combining some ring beams with the parking floor slabs in the design, not only the additional construction cost is reduced, but also the overall structural stability is improved. Combining the distribution characteristics of the ring beams, the layout of the parking spaces and passages is optimized to maximize the space utilization rate; the combined design of the ring beam and the vertical lifting passage. The space of the ring beam can be combined with the structure of the vertical lifting passage in the design. By opening passages or optimizing the positions of the elevators, the obstruction of the ring beam to the vehicle access path is 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 load-bearing capacity of the lifting system. The present application comprehensively applies technologies such as GPS positioning technology and GIS technology to the collection, management, query, reservation and navigation services of urban parking spaces, realizing the integration of real-time update, query, reservation and navigation services of parking space resources.

[0058] In step S102, according to the annular parking space layout and the ring beam utilization plan, a multi-layer annular parking area is formed in the shield tunnel working shaft, wherein the multi-layer annular parking area includes a first floor and a plurality of standard floors located below the first floor.

[0059] In a possible implementation manner, the abandoned facilities in the shield tunnel working shaft are demolished, 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 place ventilation ducts, drainage systems and power lines; according to the number of parking floors, the collaborative layout of the floor slabs and the integrated layout of the passages, the ring beam in the shield tunnel working shaft is combined and reinforced with the floor slabs, and a lifting passage for the elevator is reserved to form a first floor and a plurality of standard floors located below the first floor.

[0060] Specifically, abandoned facilities within the shaft were removed, while the main structure was retained. The existing ring beam was mechanically optimized, and the shaft walls and floor were reinforced (e.g., by grouting and adding reinforced concrete layers). The interior walls were sprayed with waterproof coating, and waterstops were installed at key joints to ensure the durability of the underground structure (internal structural reinforcement and waterproofing). Cable trays and ventilation ducts were installed outside the ring beam according to the design plan. A circular maintenance passageway was constructed using the gaps between the ring beams, equipped with a retractable maintenance platform. Prefabricated reinforced concrete floor slabs, secured by ring beam anchor bolts, formed a multi-story parking area, with AGV tracks and elevator shafts reserved on each floor.

[0061] This application's underground parking garage utilizes a cylindrical, multi-story design, maximizing parking capacity through the synergy of a circular layout and vertical lift access. The parking spaces are primarily arranged in a circular structure, with a central vertical space reserved for vehicle lifts, optimizing access paths and shortening access times.

[0062] In a possible implementation, an exhaust fan and an air duct are installed at the bottom of the shield tunnel working shaft, and the air duct is connected to the shutters on the ground.

[0063] Specifically, multi-story parking slabs are set up, a circular layout is adopted to optimize space utilization, ventilation ducts (combined with bottom-of-the-pit exhaust fans and ground shutters), drainage pumps and fire sprinkler systems are installed.

[0064] This application repurposes the abandoned large-diameter circular working shaft of an intercity railway shield tunnel into an underground cylindrical three-dimensional parking garage, fully utilizing existing underground space resources, reducing land waste and construction costs, and achieving a functional transformation and upgrade of infrastructure. An exhaust fan and air duct will be installed at the bottom of the shaft, connecting the air duct to the high louvers between the above-ground facilities to form an effective exhaust system. This design fully utilizes the advantages of natural ventilation in the shaft and, combined with mechanical ventilation, ensures air quality within the garage.

[0065] In step S103, an elevator is installed on the reserved lifting channels on 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.

[0066] In a possible implementation, the ring beam in the shield tunnel working shaft is used as a fixed anchor point, and lifting rails are installed on the reserved lifting passages of the first floor and multiple standard floors; and an elevator is installed on the lifting rails.

[0067] 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.

[0068] In a possible implementation, a corresponding inner-ring rotating platform is installed on each of the standard floors to enable independent rotational drive for each of the standard floors.

[0069] Specifically, multiple parking boards (arranged in a ring) and a first-floor rotating platform (the first floor does not rotate) are installed, and infrared sensors and vehicle adjustment devices are equipped.

[0070] In a possible implementation, corresponding running tracks and automatic charging stations are installed on the first floor and each of the standard floors respectively; carriers are deployed on the running tracks corresponding to the first floor and each of the standard floors, the initial position of the carrier is located at the center inside the inner-ring rotating platform, and the carrier is connected to the automatic charging station.

[0071] Specifically, AGV carrier running tracks are laid in each parking area, and automatic charging stations are set up.

[0072] The AGV carrier and lift of the present application are used for vehicle access. The AGV (Automated Guided Vehicle) carrier is used to achieve efficient lifting and precise access operations of vehicles. The AGV carrier based on autonomous navigation technology can flexibly move in the vertical and horizontal channels of the parking garage, accurately dispatch vehicles from the ground entrance to each floor's parking space, 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 running trajectory to avoid path conflicts and improve the overall access 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 to the parking management system to further achieve unmanned and intelligent operations.

[0073] In a possible implementation, a smart cloud platform is deployed, integrating license plate recognition, parking space allocation, and path planning algorithms, and cameras and thermal imaging sensors are installed to monitor the garage status in real time.

[0074] The present application integrates a highly intelligent parking management system. Combining with the Internet of Things technology, it realizes functions such as dynamic parking space allocation, license plate recognition, automatic charging, and remote reservation. The parking management system dynamically adjusts resource allocation by real-time monitoring of the parking space usage situation, reducing the vacancy rate and queuing time. At the same time, the system can collect data such as vehicle entry and exit flow and parking duration, providing a basis for optimization strategies for the parking garage operator. The user side can remotely reserve a parking space through a mobile application and obtain intelligent navigation and voice guidance when entering the parking garage, greatly improving the convenience of the parking experience.

[0075] In the embodiments of the present application, the specific process of transforming a working well into a parking lot is as follows: First, the internal structure of the original working well is demolished. Subsequently, the ring beam inside the well is structurally optimized and transformed, and a vertical lift is set as the core equipment for vehicle access. At the same time, the floor slabs of each parking lot layer are installed on the basis of the ring beam to form a multi-layer circular parking area. After the vehicle enters the parking lot, through the collaborative operation of the AGV parking robot and the vertical lift, the intelligent access of the vehicle is realized, providing an efficient and convenient unmanned parking service. The entire system is monitored and managed by the intelligent cloud platform throughout the process, covering functions such as vehicle access scheduling, parking space allocation, and toll settlement, comprehensively empowering the efficient operation of the intelligent parking lot. This design not only improves the parking efficiency but also optimizes the resource utilization, providing an intelligent solution for urban parking in modern times.

[0076] Compared with the transformation of the abandoned space of the rectangular ventilation shaft in the subway in the related technology, see Figure 6 and Figure 7 , if an abandoned circular working well is used to transform an underground parking lot, taking a working well with a diameter of 36m and a depth of 50m as an example, the 36m diameter working well can be transformed into two circular parking lots with a diameter of 18. A hoist is set in the middle to transport vehicles to the designated parking space floor. One working well of this size can provide 300 parking spaces. There is a huge advantage in the number of parked vehicles. And the transformation itself conforms to the environmental protection concept of resource reuse. Thus, it can reasonably utilize the abandoned resources and increase the parking berths without occupying a large amount of land area, providing more parking spaces.
