Description

Technical Field

[0001] This invention relates to the field of prefabricated building rooftop parking technology, specifically to an integrated control system for prefabricated building rooftop parking lots. Background Technology

[0002] Rooftop parking refers to motor vehicle parking facilities constructed using the rooftop space of a building. Rooftop parking lots are directly attached to the main building structure, and through structural reinforcement and modification technologies, rooftop resources are transformed into efficient parking spaces, representing an important technical means to solve urban parking difficulties. Prefabricated rooftop parking refers to parking facilities assembled on-site using prefabricated components on the building roof, representing an important direction for the three-dimensional utilization of urban space.

[0003] Currently, some parking solutions for prefabricated building rooftop parking lots have emerged in the existing technology. For example, patent "CN121345365A" discloses a modular assembly and overall lifting equipment for the construction of prefabricated building rooftop parking lots. In this solution, a parking area for fuel vehicles and a parking area for new energy vehicles are planned on the roof of the building. The parking area for fuel vehicles consists of multiple frames fixedly set on the roof. A chain-type lifting mechanism is installed on the frame. The chain drives the vehicle frame to move in a circular motion, realizing the vertical transportation of vehicles to different floors.

[0004] However, the above solution uses a chain-like loop structure, where vehicle storage and retrieval rely on a single vertical transport channel. When a vehicle carrier or chain link fails, the entire loop will be forced to stop, and all vehicles will be unable to be stored or retrieved. This results in low system reliability. Furthermore, when a vehicle needs to be retrieved, the entire chain must be driven until the vehicle carrier containing the target vehicle rotates to the entry / exit position before it can be retrieved. This leads to a long waiting time for vehicles to reach the entry / exit position, resulting in low efficiency, inconvenience in operation, and a poor user experience.

[0005] Therefore, it is necessary to study an integrated control system for prefabricated building rooftop parking lots. Summary of the Invention

[0006] Therefore, the purpose of this invention is to provide an integrated control system for prefabricated building rooftop parking, which effectively solves the problems of low system reliability, low storage and retrieval efficiency, and inconvenient operation caused by the reliance on a single vertical transport channel in existing chain-loop rooftop parking technology.

[0007] To achieve the above objectives, the technical solution adopted by this invention is: an integrated control system for a prefabricated building rooftop parking lot, comprising a control module, a lifting unit, a transfer unit, and a parking unit; the control module is used to realize centralized monitoring and intelligent scheduling of the entire system; the lifting unit is fixedly installed on the outer wall of the main building from top to bottom, used to vertically lift vehicles from the ground to the roof height, and to vertically lower vehicles from the roof to the ground floor; the parking unit is set on the building roof, including a charging area with a planar open structure and a parking area with a three-dimensional frame-like storage structure, the parking area being distributed on both sides of the charging area, used for parking, charging, and zoned management of different types of vehicles; the transfer unit is set within the rooftop parking area, used to unload vehicles lifted to the roof from the lifting unit and transfer them to the target parking spaces in the parking area.

[0008] Furthermore, the control module includes an information acquisition unit, a scheduling decision unit, an execution control unit, and a communication unit for signal connection between the various units; the information acquisition unit is used to collect vehicle status and parking space occupancy status in real time; the scheduling decision unit is used to construct a dynamic behavior profile based on the vehicle's historical parking records, and classify the vehicle's attributes and assign parking spaces accordingly; the execution control unit is used to issue timing action commands to the lifting unit and the transfer unit.

[0009] Furthermore, the scheduling decision unit can classify pre-stored vehicles into permanent vehicles, predictable vehicles, and temporary vehicles.

[0010] Furthermore, the charging area of ​​the parking unit is located in the middle of the roof, and the parking areas are symmetrically distributed on the front and rear sides of the charging area. The parking area includes four storage areas, each storage area has multiple parking cells, and each storage area has a docking area on one side. There are four sets of lifting units, which correspond to the docking areas of the four storage areas respectively, so as to realize parallel scheduling of independent operation of multiple channels and multiple zones.

[0011] Furthermore, the lifting unit includes an elevator cabin vertically installed on the exterior wall of the main building, a vehicle base adapted to be slidably installed in the elevator cabin, and a lifting device for driving the vehicle base to rise and fall. The bottom of the elevator cabin is provided with a vehicle inlet on the side away from the main building, and the top of the elevator cabin is provided with a vehicle outlet on the side close to the main building.

[0012] Furthermore, the vehicle base is a box-type support platform, which has a grid-like support plate inside for parking vehicles, and the bottom of the support plate has clearance space for the transfer unit to enter; the vehicle base is also equipped with multiple cameras that are connected to the control module to collect real-time image data inside the vehicle base to confirm the parking status of the vehicle and whether there are any people staying in the cabin.

[0013] Furthermore, the four storage areas are each provided with two rows of frame structures spaced longitudinally along the left and right sides of the roof, forming a central aisle between adjacent frame structures, and each row of frame structures has multiple parking cells in the vertical direction. The transfer unit can move along the central aisle to perform vehicle storage and retrieval operations.

[0014] Furthermore, each of the storage areas includes a permanent vehicle area, a predictable vehicle area, and a temporary vehicle area. The permanent vehicle area is located away from the docking area, the temporary vehicle area is located close to the docking area, and the predictable vehicle area is located between the permanent vehicle area and the temporary vehicle area. The number of parking space cells in the predictable vehicle area is greater than that in the permanent vehicle area and the temporary vehicle area.

[0015] Furthermore, the transfer unit includes an AGV transfer trolley and a lifting platform that carries the AGV transfer trolley. The lifting platform can move within the parking area and adjust its height to lift the AGV transfer trolley to different levels within the parking area. The AGV transfer trolley can drive out independently of the lifting platform and is used for loading and unloading vehicles between the vehicle base, the lifting platform, and the cells of the parking area.

[0016] Furthermore, the control module includes a human-vehicle joint vertical transportation control mode. When the information collection unit identifies a green-plate new energy vehicle and receives a charging request from the new energy vehicle, the control module controls the lifting unit to vertically lift the vehicle owner and the new energy vehicle together to the roof height and drive into the charging area for charging. After charging is completed, the vehicle owner drives back to the lifting unit and descends to the ground level with the vehicle to leave.

[0017] The beneficial effects of the above technical solution are: This invention sets up the lifting unit and the transfer unit independently. When storing or retrieving a vehicle, only the transfer unit corresponding to the target vehicle needs to be scheduled to perform the operation. No other equipment needs to be linked. The storage and retrieval time is greatly shortened. Especially during peak periods when multiple users are storing and retrieving concurrently, the system throughput is significantly improved, and the reliability of the entire system is greatly improved.

[0018] This invention adopts a three-layer, three-dimensional, dense frame-type storage structure, which achieves a parking space density far higher than that of flat parking on the same roof area; at the same time, the lifting unit is externally mounted on the building's exterior wall, without occupying the effective roof area, thus maximizing the utilization of roof space.

[0019] This invention enables differentiated zoning and scheduling of permanent, predictable, and temporary vehicles. Temporary vehicles that stop briefly are assigned to areas close to the docking area and central aisle, predictable vehicles with regular commuting patterns are placed in the most abundant dedicated areas, and permanent vehicles that park for extended periods are assigned to relatively remote locations away from the docking area. Predictable vehicles are scheduled in reverse order based on their expected departure time, with vehicles leaving earlier being placed closer to the exit, significantly reducing waiting time for vehicle retrieval. This differentiated zoning and scheduling frees up high-turnover parking space resources near entrances and exits, achieving high-speed turnover and efficient management of vehicle flow within the rooftop space.

[0020] In this invention, new energy vehicles support convenient processes such as simultaneous vehicle and person access, rooftop charging, and elevator access, fully meeting the needs of different types of users. Users only need to scan a code or operate through the APP to store and retrieve the vehicle, without any manual intervention, making the user experience convenient and efficient.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1: This example aims to provide an integrated control system for rooftop parking lots of prefabricated buildings, which is mainly used to realize the fully automated storage and retrieval of fuel vehicles and new energy vehicles in rooftop parking lots, intelligent zone scheduling, and integrated management of rooftop charging for new energy vehicles.

[0024] like Figure 1-9 As shown, the integrated control system for prefabricated building rooftop parking provided in this embodiment includes a control module, a lifting unit, a transfer unit, and a parking unit. The control module is used to realize centralized monitoring and intelligent scheduling of the entire system. The lifting unit is used to vertically lift vehicles from the ground to the roof height. The transfer unit is used to unload the vehicles lifted to the roof and transfer them to the target parking spaces in the parking unit. The parking unit is set on the roof of the main building 1 and specifically includes a parking area 5 and a charging area 6 for parking, charging, and zoned management of different types of vehicles.

[0025] Specifically, in this embodiment, the lifting unit includes an externally mounted structure that is fixedly installed on the outside of the building's exterior wall from top to bottom. In this embodiment, there are a total of four sets of lifting units, each with the same structure, corresponding to the four zones of the parking unit. This realizes an independent operation mechanism with multiple channels and zones, and maximizes the distribution of roof space, thereby improving the utilization rate of space.

[0026] In this embodiment, the lifting unit includes a lifting device 9, a vehicle base 8, and an electrical control system. The lifting device 9 includes a steel frame vertically fixed to the exterior wall of the building. The steel frame is surrounded by fixed side plates to form a rectangular elevator car 2. A drive source is provided at the top of the elevator car 2. In this embodiment, a conventional winch hoisting and lifting structure is used. The vehicle base 8 is fitted and guided to slide inside the elevator car 2. A wire rope is provided at the output end of the winch and fixedly connected to the top of the vehicle base 8, thereby driving the vehicle base 8 to slide up and down along the internal steel frame. An inlet is provided at the lower part of the elevator car 2 facing the outside of the building, and an outlet is provided at the upper part of the elevator car 2 facing the building. Automatic safety doors 3 are installed at the ground floor entrance and the roof docking area exit, so that vehicles can enter the vehicle base 8 from the elevator car 2 inlet. Then, the lifting device 9 drives the vehicle base 8 to lift the vehicle smoothly upward to the outlet position. After the transfer unit unloads the vehicle from the vehicle base 8, the lifting device 9 drives the empty vehicle base 8 to return to its original position.

[0027] Furthermore, in this embodiment, the vehicle base 8 is a box-type support platform guided and positioned at the bottom of the elevator cabin 2. Its size is adapted to standard vehicles. Inside the vehicle base 8, there is a grid-like support plate for parking vehicles and supporting the wheels. The bottom of the support plate has clearance space so that when docking at the roof level, the AGV transfer trolley 12 can smoothly drive into the lower space of the grid-like support plate, thereby safely unloading or transferring the vehicle. In addition, multiple cameras are installed inside the vehicle base 8. Each camera is connected to the control module to collect real-time image data of the vehicle base 8 inside the elevator cabin 2 from all directions. Specifically, when a vehicle drives into the vehicle base 8 from the ground, the camera automatically captures image data of the vehicle base 8. When parking a vehicle, the camera can identify the situation inside the vehicle base 8 and confirm that the owner has left and no personnel remain in the cabin before allowing the door to close and lift.

[0028] like Figure 4-7 As shown, the parking unit is located on the building roof and includes a charging area 6 and a parking area 5. In this embodiment, the charging area 6 is located in the middle of the roof, and the parking areas 5 are distributed on the front and rear sides of the charging area 6, forming a passageway for vehicle movement between the parking area 5 and the charging area 6. In this embodiment, the parking area 5 includes four storage areas: A, B, C, and D. Areas A and B are located in front of the charging area 6, and areas C and D are located in rear of the charging area 6. Each storage area has a dedicated docking area a, b, c, or d on one side for docking with the lifting unit to receive vehicles transported from the lifting unit. In this embodiment, docking areas a and b are adjacent and located between areas A and B, and docking areas c and d are adjacent and located between areas C and D. Each docking area is equipped with an AGV transfer vehicle 12 for transporting vehicles to the storage areas on the left and right sides, respectively.

[0029] In this embodiment, the parking unit adopts a three-dimensional, dense frame-type storage structure. Specifically, two rows of frame structures are arranged longitudinally along the left and right sides of the roof. Each row of frame structures has evenly distributed parking cells. In this embodiment, each storage area has three layers in the vertical direction, including a bottom layer, a middle layer, and a top layer, forming a three-dimensional storage space. During actual construction, the floor height of the storage area and the number of cells can be dynamically planned according to the actual load-bearing capacity of the building during construction. A central aisle 10 is formed between the two rows of frame structures. This central aisle 10 runs longitudinally through the entire storage area. The AGV transfer cart 12 can travel back and forth in the central aisle 10 to accurately target any layer and any cell for unobstructed access, without the need to move other vehicles like in traditional chain-driven garages, making access convenient.

[0030] Furthermore, to maximize vehicle storage and retrieval efficiency, each storage area includes three sub-areas. Taking area A as an example, it includes A1 permanent vehicle area, A2 predictable vehicle area, and A3 temporary vehicle area. Each sub-area has several parking cells, and the predictable vehicle area has more cells than the permanent and temporary vehicle areas. Thus, regardless of which floor or cell a vehicle is parked in, the lifting platform can move back and forth along the central aisle 10, facilitating storage and retrieval of vehicles in any cell on the front, rear, or sides without having to move other vehicles or their positions.

[0031] In this embodiment, the charging area 6 for new energy vehicles is located in the center of the roof, forming an open-plan parking area 5. Parking space markings are painted on the ground. A driveway connects the charging area 6 to the storage frame of the parking area 5, allowing vehicle owners to drive directly from the docking area to the charging area 6 for charging after unloading at the elevator car 2. A conventional passenger elevator 7 is located on one side of the roof, allowing drivers to descend from the roof to the ground after parking and plugging in the charging pile, or to ascend from the ground to the roof to retrieve the vehicle after charging is complete. A photovoltaic charging canopy is erected above the charging area 6, providing shade and rain protection for parked vehicles and generating electricity to supplement the parking lot's local area network. Each new energy vehicle parking space is equipped with a charging pile, providing efficient integrated parking and charging services.

[0032] It should be noted that parking area 5 can accommodate both gasoline vehicles and new energy vehicles. However, only when new energy vehicles need to go to the roof for charging can the system support vertical transportation of both the vehicle and the person. This is because new energy vehicle owners need to manually plug and unplug the charging gun on the roof. When a new energy vehicle owner chooses to go to the roof for charging, the system supports vertical transportation of both the vehicle and the person. When the camera recognizes a green-plate vehicle, the owner is allowed to remain in the vehicle while the lifting device 9 smoothly lifts the person and vehicle to the roof. After reaching the roof docking area, the system controls the AGV transfer vehicle 12 to give way, allowing the owner to drive directly out of the elevator cabin 2 to the new energy vehicle space in the open charging area 6 in the middle of the roof for manual charging.

[0033] like Figure 7-9As shown, in this embodiment, the transfer unit includes an AGV transfer trolley 12 and a lifting platform 11. The AGV transfer trolley 12 is located on the upper surface of the lifting platform 11. In this embodiment, the lifting platform 11 is a common existing scissor-type hydraulic lifting platform 11 or screw-type lifting platform 11 structure that can bear heavy loads. It is equipped with wheels at the bottom and can move longitudinally along the central aisle 10 to any target position in the docking area or storage area. Initially, the lifting platform 11 is in its retracted state at its lowest height, used to dock with the exit of the elevator cabin 2, allowing the transfer trolley 12 to move onto the vehicle base 8 inside the elevator cabin 2, transferring the vehicle to the AGV transfer trolley 12. Afterwards, the lifting platform 11 can drive the transfer trolley 12 to move along the central aisle 10, transporting it to the target cell at the corresponding height in the corresponding zone according to the instructions issued by the control module. Then, the transfer trolley 12 unlocks from the lifting platform 11, transports the vehicle to the carrier plate in the corresponding cell, and then resets to the upper surface of the lifting platform 11. When the vehicle is located at a high floor, the height of the lifting platform 11 itself or the height of the transfer trolley 12 can be adjusted to be flush with the carrier plate surface of the middle or top floor cell, for storing and retrieving vehicles at high floors, so that the vehicle can stably reach the target floor.

[0034] In this embodiment, the AGV transfer trolley 12 is set on the upper surface of the lifting platform 11. It is an automated guided vehicle. The AGV transfer trolley 12 is a mature existing vehicle transfer technology, and its specific structure will not be described in detail here. Under the control module's scheduling, the AGV transfer trolley 12 can move independently of the lifting platform 11. Specifically, it can: drive out from the surface of the lifting platform 11, enter the vehicle carrier base 8 inside the elevator cabin 2, transfer the vehicle from the vehicle carrier base 8 to the AGV transfer trolley 12, and then return to the surface of the lifting platform 11 with the vehicle; drive out from the surface of the lifting platform 11, enter the carrier plate in the target cell, unload the vehicle from the AGV transfer trolley 12 onto the cell carrier plate, and then return to the surface of the lifting platform 11 empty; drive out from the surface of the lifting platform 11, enter the carrier plate in the target cell, transfer the vehicle from the cell carrier plate to the AGV transfer trolley 12, and then return to the surface of the lifting platform 11 with the vehicle; drive out from the surface of the lifting platform 11, enter the vehicle carrier base 8 inside the elevator cabin 2, unload the vehicle from the AGV transfer trolley 12 onto the vehicle carrier base 8, and then return to the surface of the lifting platform 11 empty.

[0035] like Figure 1As shown, the control module in this embodiment includes an information acquisition unit, a scheduling decision unit, an execution control unit, a human-machine interaction unit, and a communication unit for signal connection between the various units. The information acquisition unit includes acquisition terminals such as ground induction coils, ultrasonic parking space sensors, infrared beam sensors, and cameras (not shown in the figure, as this is prior art and will not be described in detail here). These terminals are installed at the entrance of the ground floor lifting unit, inside the vehicle base 8 of the elevator cabin 2, in each docking area on the roof, and in each area of ​​the parking unit. When a vehicle enters the entrance area, the ground induction coil at the entrance senses the arrival signal of the vehicle and triggers the information acquisition process. Multiple cameras inside the elevator cabin 2 can collect image data of the vehicle base 8 in the elevator cabin 2 from all directions in real time. The license plate recognition camera captures the image of the vehicle license plate and performs OCR recognition to extract the license plate number. Sensors in each area of ​​the roof are used to monitor the occupancy status of each parking cell in real time. The information acquisition unit transmits the raw data of the above vehicle information to the scheduling decision unit through the communication unit for vehicle identification and scheduling.

[0036] The dispatch decision unit is located in an integrated control cabinet on the roof. It receives vehicle information from the information collection unit and retrieves the vehicle's historical parking records stored in the data management unit using the license plate number as an index. This includes data such as the entry time, exit time, parking duration, and parking area for each parking session. Based on this historical data, a dynamic behavior profile of the vehicle is constructed, and the vehicle is classified and determined. (1) Permanent vehicles: vehicles with strong parking patterns and long parking times; if the system finds that the license plate belongs to a fixed owner of the building or a monthly or annual pass holder who has purchased a long-term parking space, or if the frequency of the vehicle's parking time exceeding the set threshold reaches the set proportion within the past set period, for example, if the frequency of a vehicle's parking time exceeding 12 hours / time in the past 30 days reaches 70%; then such vehicles have relatively fixed access times, and the system directly determines them as permanent vehicles and assigns them to the A1 / B1 / C1 / D1 storage area. This area is set in a location relatively far from the docking area to free up parking space resources near the entrance and exit for high-frequency turnover vehicles.

[0037] (2) Predictable vehicles: have certain travel patterns, but the parking time is moderate, or based on the user's active reservation behavior or clear time interaction feedback; if the system recognizes that the user has high frequency and regular commuting characteristics, such as parking at 8 am from Monday to Friday and picking up the car at 6 pm, or parking time within a set period in the past (e.g., 4-12 hours / time), and the entry and exit times show certain regularity, that is, entering and exiting at roughly the same time every day, or the car owner has reserved the roof parking space in advance through the mobile phone before the trip and entered the expected parking time on the reservation interface, such as parking for 4 hours due to a business meeting, or non-long-term rental car owners directly entered the specific departure time on the screen when scanning the code to park the car on the ground central control screen, then the above vehicles are given priority to be allocated to the A2 / B2 / C2 / D2 storage area.

[0038] The number of parking spaces in this area exceeds that of the permanent and temporary vehicle areas to meet the parking needs of a large number of predictable vehicles. Simultaneously, the system can reserve parking spaces and plan retrieval routes in advance based on the vehicle's travel patterns or reservation information. Furthermore, the central dispatch unit can sort vehicles in reverse order based on the departure time input by the owner; vehicles with earlier departure times are given priority for placement in lower or outer slots closer to the docking area and easier to retrieve. This allows the AGV transfer cart 12 to pre-position vehicles in the central aisle 10, significantly reducing the waiting time for owners to retrieve their vehicles.

[0039] (3) Temporary vehicles: randomly parked with short stays; if the vehicle has no historical parking record or its historical parking duration is generally less than 4 hours / time, or the parking time period has no obvious pattern, it is considered a dynamic vehicle that stops and goes immediately, and will be assigned to storage area A3 / B3 / C3 / D3. This area is located near the docking area and central aisle 10 to facilitate quick vehicle access and reduce driving and waiting time in the parking lot. It should be noted that the above time classification thresholds can be dynamically adjusted according to the actual operational needs of the parking lot.

[0040] Based on the target storage area, sub-area and specific cell determined above, the scheduling decision unit further plans and generates the walking path of the transfer unit, and generates the coordinated action instruction sequence of the lifting unit, the lifting platform 11 and the AGV transfer trolley 12, which are sent to the execution control unit one by one in sequence.

[0041] The execution control unit receives action instructions from the scheduling decision unit and controls the hoist motor of the lifting unit to control the lifting and lowering of the car base 8 in the elevator car 2, the movement and height adjustment of the lifting platform 11, and the entry and exit of the AGV transfer trolley 12. The execution control unit can also collect the real-time operating status of each device and feed it back to the scheduling decision unit for status monitoring and dynamic adjustment.

[0042] The human-machine interaction unit includes a touch-screen all-in-one machine 4 located at the entrance of the elevator car 2 on the ground floor and the exit of the elevator car 2 on the roof floor, integrating functions such as QR code scanning, display screen, and voice prompts; auxiliary central control screens located at the entrances of each docking area and charging area 6 on the roof; and an APP and WeChat mini-program deployed on the user's mobile phone. Users can initiate operations such as parking and retrieval requests, checking parking space status, paying parking fees, and reserving retrieval time through any interactive terminal. In addition, during the parking process of fuel vehicles, after the vehicle drives from the ground into the vehicle carrier base 8, the camera automatically captures image data inside the vehicle carrier base and displays it in real time on the central control screen through the human-machine interaction unit, allowing the driver to confirm the vehicle's parking position. At the same time, before closing and raising the door, the camera identifies the situation inside the vehicle carrier base, confirming that the owner has left and no one remains in the cabin before allowing the door to close and raise.

[0043] Working principle description: The integrated control system for prefabricated building roof parking lots provided in this embodiment includes the following process in actual application: (1) Parking process for fuel-powered vehicles First, the driver drives the vehicle to the entrance of the lifting unit on the ground floor of the building. The ground induction coil at the entrance senses the arrival signal of the vehicle. The license plate recognition camera of the vehicle recognition unit captures the image of the vehicle license plate and performs OCR recognition to extract the license plate number. The scheduling decision unit uses the license plate number as an index to retrieve the vehicle's historical parking records, classifies the vehicle, and then allocates the target storage area, target sub-area, and target cell according to the classification results. For example, sub-area A2 in area A and cell No. 3 in the middle layer. It also generates a sequence of coordinated action instructions for the lifting unit, the lifting platform, and the AGV transfer trolley. Then, the control unit controls the elevator car entrance automatic safety door of the lifting unit to open. The vehicle drives into the car carrier base inside the elevator car through the entrance. The driver turns off the engine, pulls the handbrake and leaves the elevator car. Multiple cameras inside the car carrier base collect image data inside the car carrier base in real time. After confirming that the car owner has left and that no one is left in the car, the control unit closes the entrance automatic safety door and starts the winch hoisting and lifting device. The steel wire rope pulls the car carrier base to slide smoothly upward along the steel frame, vertically lifting the vehicle from the ground floor to the roof floor. After the vehicle carrier base is raised to the roof level, the control unit opens the automatic safety door at the elevator exit, aligning the vehicle carrier base with the target docking area. At this point, the lifting platform drives the AGV transfer trolley to the docking area. The bearing surface of the lifting platform is flush with the bottom surface of the elevator exit. The AGV transfer trolley drives out from the lifting platform surface and travels to the clearance space under the grid-like support plate of the vehicle carrier base to transfer the vehicle from the vehicle carrier base to the AGV transfer trolley. Then, it carries the vehicle back to the lifting platform surface. The lifting platform travels along the central aisle track into the target storage area. The height is adjusted according to the floor position of the target cell so that its bearing surface is flush with the surface of the target cell's carrier plate. The AGV transfer trolley unlocks from the lifting platform surface and drives out into the target cell, unloading the vehicle from the AGV transfer trolley onto the cell's carrier plate. Then, it returns to the lifting platform surface empty. The system confirms that the vehicle is in place, and the storage is complete.

[0044] (2) Process for picking up fuel-powered vehicles Users initiate vehicle retrieval requests via the ground-level central control screen, mobile app, or WeChat mini-program. They enter the license plate number and click "retrieve vehicle." The human-machine interface unit transmits the request to the scheduling decision unit. The scheduling decision unit retrieves the license plate number, obtains the target storage area, target sub-area, target cell, and floor information of the vehicle, and then issues instructions to the lifting platform and AGV transfer trolley. The lifting platform travels along the central aisle track into the target storage area, adjusts its height to align the AGV transfer trolley with the target cell's carrier surface, and transfers the vehicle onto the AGV transfer trolley. The AGV transfer trolley then returns to the lifting platform surface, resets, and travels to the corresponding docking area. Simultaneously, the elevator car rises from the ground floor to the roof floor, docking with the docking area at the same level. The exit automatic safety door opens, and the AGV transfer trolley unloads the vehicle onto the carrier base before returning empty to the lifting platform surface. The elevator car exit automatic safety door closes, and the carrier base slides smoothly downwards along the steel frame, lowering the vehicle vertically from the roof floor to the ground floor. The elevator car entrance automatic safety door opens, and the owner drives away, completing the vehicle retrieval process.

[0045] (3) Process for storing and retrieving new energy vehicles without charging When a new energy vehicle does not require charging and the user chooses to park the vehicle in the parking area, the new energy vehicle will be stored and retrieved in the same way as a fuel vehicle. The retrieval process is the same as that for fuel vehicles, so we will not go into details here. In this mode, the new energy vehicle is simply stored in the three-dimensional unit of the parking area as a regular vehicle and no charging service is provided. When retrieving the vehicle, it can be retrieved in the same way as a regular vehicle.

[0046] (4) Charging and parking process for new energy vehicles First, the driver arrives at the entrance of the lifting unit on the ground floor. The induction coil at the entrance senses the vehicle's arrival signal, and the vehicle recognition unit captures and identifies the license plate number, determining that the vehicle is a green-plate new energy vehicle. The user selects "charging mode" through the central control screen, and the decision-making unit queries the parking space status database of the charging area to determine if there are any available parking spaces. If there are no available parking spaces, the central control screen displays a "charging parking space full" message. If there are available parking spaces, the automatic safety door at the elevator entrance opens, and the central control screen displays a "please enter" message. The vehicle drives into the vehicle carrier base inside the elevator cabin, with the driver remaining inside. The camera inside the vehicle carrier base collects image data in real time. The vehicle is turned off and the handbrake is engaged. Then, the automatic safety door at the elevator entrance closes, the vehicle carrier base moves the vehicle upwards, and the automatic safety door at the elevator exit opens, allowing the vehicle carrier base to dock with the target docking area at the same level. The system controls the AGV transfer vehicle to avoid obstacles. The driver drives the vehicle directly from the carrier base out of the elevator cabin, along the docking area and through the vehicle passage into the charging area in the middle of the roof to start charging. The charging pile automatically recognizes the vehicle and starts billing. The driver leaves the charging area, walks to the conventional passenger elevator on one side of the roof, takes the passenger elevator down to the ground floor and leaves. The system obtains the charging status through the communication interface of the charging pile, updates the parking space status in the charging area, marks the parking space as "charging", and records the charging power in real time.

[0047] (5) New energy vehicle charging and retrieval process Users can check the vehicle charging status via a mobile app or mini-program. After confirming that charging is complete or has been terminated early, they can initiate a vehicle retrieval request. Users take the conventional passenger elevator on the roof side from the ground floor to the roof floor, unplug the charging gun, and confirm that charging is complete. The user then drives the vehicle from the charging area through the driveway to the docking area. At the docking area, the user scans a code on the central control screen. The human-machine interface unit transmits the vehicle retrieval command to the dispatch decision unit, which controls the elevator car to rise from the ground floor to the roof floor and dock at the docking area. The exit automatic safety door opens, and the driver drives the vehicle directly from the docking area onto the vehicle carrier base inside the elevator car. The vehicle remains inside the car as it descends. The exit automatic safety door closes, and after the vehicle carrier base descends to the ground floor, the elevator car entrance automatic safety door opens, and the vehicle exits through the entrance, allowing the user to leave. The system simultaneously updates the parking space status in the charging area, marks the parking space as "vacant," and ends the charging billing.

[0048] The integrated control system for prefabricated building rooftop parking lots provided in this embodiment achieves automated and intelligent management of rooftop parking lots through the collaborative integration of various units, significantly improving storage and retrieval efficiency. It achieves a parking space density far higher than that of flat parking on the same roof area. At the same time, the lifting unit is mounted on the exterior wall of the building, without occupying the effective area of ​​the roof, thus maximizing the utilization of the roof space. Furthermore, the human-computer interaction is convenient, providing a good user experience.

[0049] Example 2: The similarities between this example and Example 1 will not be repeated here. The difference is that in this example, for the four storage areas A, B, C and D of the parking unit, each storage area is directly treated as an independent whole for attribute determination and planning.

[0050] Specifically, one of the four storage areas, such as Area A which is far from the docking area or has a long walking path, is designated as a unique permanent vehicle area. Since permanent vehicles are usually long-term leases or vehicles owned by fixed owners, they are parked for a long time and have a very low turnover rate. Concentrating them in an independent area can minimize the interference of high-frequency vehicle access to the area and facilitate the implementation of high-density, low-movement static management.

[0051] Two storage areas, such as the centrally located and largest capacity areas B and C, are designated as predictable vehicle zones. Since vehicles with commuting patterns or those that have made advance reservations constitute the largest number and proportion of vehicles in the daily rooftop parking lot, allocating two entire zones can provide extremely ample storage units. At the same time, the large-scale management of the two entire zones makes it easier for the scheduling decision-making unit to perform large-scale reverse sorting and AGV pre-moving based on the departure time input by the vehicle owner, greatly improving the overall turnover efficiency of the main vehicle flow.

[0052] The remaining D area is designated as the only temporary vehicle area. Temporary vehicles are high-frequency mobile vehicles that "stop and go". They can be confined to a single area closest to the vertical lifting channel to ensure the shortest travel path for AGV transfer vehicles, achieve fast read and retrieval, and reduce dynamic interference from other storage areas.

[0053] This embodiment, compared to searching for different sub-areas within a single zone, employs a more streamlined "dedicated area" assignment logic, making it suitable for large prefabricated rooftop parking lots with extremely busy vehicle traffic. This system operates more efficiently and systematically, further enhancing the space utilization efficiency and operational management flexibility of the rooftop parking lot.

[0054] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
