A three-compartment integrated circulating logistics elevator and its collaborative scheduling method

Abstract

This invention discloses a three-compartment integrated circulating logistics elevator and its collaborative scheduling method. The elevator car frame is vertically divided into a logistics compartment, a passenger compartment, and a recovery compartment. The three compartments are connected to the same traction system and each has an independent side door system. The top of the logistics compartment and the bottom of the recovery compartment each have an openable / closable interface. The scheduling method prioritizes the passenger compartment: when target floors are the same, it enters a follow mode for synchronous operation; when target floors are different and time permits, it enters a disengagement mode, independently operating to other floors and returning while the passenger compartment is stopped. This invention achieves parallel operation of passenger transport, logistics, and recovery functions within a single shaft, improving shaft capacity utilization.

Description

Technical Field

[0001] This invention relates to the field of elevator and smart building technology, and in particular to a three-compartment integrated circulating logistics elevator and its collaborative scheduling method. Background Technology

[0002] With the rapid development of cities and the widespread adoption of e-commerce, the demand for logistics distribution and waste recycling within high-rise buildings is increasing daily. Building vertical transportation systems face the complex situation of simultaneously handling three tasks: passenger commuting, goods delivery, and waste recycling. Existing technologies addressing this challenge mainly fall into two categories:

[0003] One approach involves setting up a single elevator car within the same elevator shaft, using a time-sharing system to perform passenger or freight transport functions at different times. While this approach saves shaft space, it presents hygiene and safety risks because people, goods, and waste share the same car space. Furthermore, it cannot handle multiple tasks concurrently, and transport efficiency is limited by the carrying capacity of a single car.

[0004] Another approach involves installing separate passenger and freight elevators within the same building, each driven independently by its own traction drive system. While this achieves separation of passengers and freight, it requires multiple elevator shafts, significantly increasing the building's core area and construction costs. More importantly, with each elevator operating independently, dynamic capacity complementarity is impossible. When one type of task is idle while another is congested, the overall utilization rate of the elevator shafts is difficult to achieve.

[0005] Furthermore, when multiple functional compartments are set up within the same car frame, since each compartment is fixedly connected to the same car frame, the existing scheduling method can only control the synchronous operation of the entire car. Logistics or recycling operations must follow the docking plan of the passenger compartment and cannot be carried out independently during the gaps in passenger tasks, resulting in the elevator capacity not being fully utilized during the time window.

[0006] Therefore, there is an urgent need for an elevator system and scheduling method that can integrate passenger transport, logistics and recycling functions within a single shaft, and fully utilize passenger stop time windows to achieve logistics and recycling operations without interfering with passenger transport. Summary of the Invention

[0007] To address the problem in existing technologies where the functional compartments within the same car frame cannot operate independently, logistics / recycling operations must stop synchronously with the passenger cabin, thus preventing the use of the passenger cabin's stopping time window for parallel operations and resulting in wasted elevator shaft capacity time windows, this invention proposes a three-compartment integrated circulating logistics elevator and its collaborative scheduling method.

[0008] The specific technical solution is as follows: A three-compartment integrated circulating logistics elevator, installed in a building elevator shaft, includes:

[0009] The car frame is internally divided into an upper logistics compartment, a middle passenger compartment, and a lower recovery compartment arranged vertically in sequence by fixed partitions.

[0010] The logistics compartment, the manned compartment, and the recovery compartment are connected to the same main traction drive system.

[0011] The logistics compartment, manned compartment, and recovery compartment are each equipped with an independent side-opening door system;

[0012] The top of the logistics compartment is equipped with an openable and closable interface for docking with the loading device.

[0013] The bottom of the recovery compartment is equipped with an openable and closable interface for docking with the unloading device. By dividing the single car frame vertically into a logistics compartment, a passenger compartment, and a recovery compartment, and connecting the three compartments to the same main traction drive system, a single traction system can simultaneously drive three independently functional compartments. This achieves spatial integration of passenger transport, logistics, and recovery functions within a single shaft without increasing shaft area, and avoids the increased equipment costs associated with setting up independent drive systems for each compartment. By providing independent side-opening door systems for each of the three compartments, each compartment can independently perform door opening operations on different floors, providing a physical basis for the independent operation of the logistics compartment and the recovery compartment while the passenger compartment is docked. By providing an openable and closable interface on the top of the logistics compartment, it can dock with loading devices on the upper part of the building, such as rooftop sorting devices or drone systems, to achieve automated loading. By providing an openable and closable interface at the bottom of the recovery compartment, it can dock with unloading devices on the lower part of the building, such as underground recovery systems, to achieve automated unloading. Thus, a complete material flow closed loop from rooftop loading to underground unloading is constructed vertically.

[0014] Furthermore, the openable interface at the top of the logistics compartment is a top openable door located at the top of the logistics compartment, and the openable interface at the bottom of the recycling compartment is a bottom openable door located at the bottom of the recycling compartment; the top openable door and the bottom openable door are each driven by an independent door operator and are used to dock with the loading device and the unloading device respectively.

[0015] Furthermore, the side wall of the recycling bin is provided with a recycling input port, which is used to connect with the output end of a pre-set recycling channel in the building to receive recyclables.

[0016] A collaborative scheduling method based on the aforementioned three-compartment integrated circular logistics elevator includes:

[0017] Obtain the next target floor and estimated docking time for the crew cabin;

[0018] With the operation of the manned cabin as the highest priority, the logistics cabin and the recovery cabin are controlled to operate independently based on the real-time status of the manned cabin:

[0019] When the logistics compartment or recycling compartment has the same task to be performed as the next target floor of the manned compartment, the logistics compartment or recycling compartment is controlled to enter the follow mode, and runs synchronously with the manned compartment to its target floor, and performs cargo delivery or recycling reception.

[0020] When the logistics compartment or recovery compartment has a task to be performed on a different target floor than the next target floor of the manned compartment, and detachment is feasible, the logistics compartment or recovery compartment is controlled to enter the detachment mode. During the docking of the manned compartment, it detaches from the manned compartment and runs independently to the target floor to perform the operation. It is also controlled to return to the same vertical position as the manned compartment before the manned compartment finishes docking.

[0021] The term "departure feasibility" refers to the time required for the logistics or recovery module to travel from its current position to the target floor to complete its operation and return to the location of the manned module, which is less than the difference between the estimated docking time and the preset buffer time. By prioritizing the operation of the manned module and placing passenger transportation needs first, the service quality of manned missions is ensured to be unaffected by logistics and recovery operations. By dynamically selecting the follow mode or departure mode based on the relationship between the target floor of the task to be performed and the target floor of the manned module, logistics and recovery operations can be performed in parallel during the manned module's docking time window, converting the previously idle shaft capacity during the manned module's docking into effective working time for logistics and recovery operations. By setting departure feasibility conditions, the time required for the logistics or recovery module to travel to and from the target floor is compared with the estimated docking time of the manned module. Departure is only allowed when the travel time is less than the difference between the docking time and the preset buffer time, ensuring that the departure mode does not cause the manned module to wait. This establishes a deterministic guarantee mechanism between logistics / recovery efficiency and manned service quality, achieving optimal timing scheduling under shared traction drive constraints.

[0022] Furthermore, in the disengagement mode, the target floor that the logistics module independently operates to is higher than the target floor of the manned module; the target floor that the recovery module independently operates to is lower than the target floor of the manned module.

[0023] Furthermore, in the disengagement mode, when there are multiple work tasks on other floors, the control logistics module or recovery module is to dock at each target floor in sequence to perform the work. The docking order is determined based on the relative positional relationship between each target floor and the target floor of the manned module, as well as the estimated docking time.

[0024] Furthermore, the feasibility of the detachment is determined through the following steps:

[0025] Based on the current position of the logistics or recovery compartment, at least one target floor to be worked on, the rated speed and acceleration of the elevator, and the estimated docking time of the manned compartment, calculate the total time T_return required to complete the work and return to the same vertical position as the manned compartment after detachment;

[0026] If T_return is less than the difference between the estimated docking time T_s and the preset safety buffer time ΔT, then the detachment is deemed feasible.

[0027] Otherwise, if detachment is deemed impossible, it will be controlled to enter follow mode or standby state;

[0028] The total time T_return includes at least the time it takes for the escape capsule to travel from its current position to each target floor, the loading and unloading time at each target floor, and the time it takes to return from the last target floor to the location of the manned capsule.

[0029] Furthermore, if the logistics module or recovery module fails to return to the same vertical position as the manned module before the manned module finishes docking during the disengagement mode due to equipment failure or operation timeout, the logistics module or recovery module will stop its current operation and return to the location of the manned module. If returning is not feasible, it will dock at its current floor to avoid danger, and the subsequent operation path will be replanned according to the next target floor of the manned module, so that the logistics module or recovery module can re-coordinate with the manned module in subsequent docking cycles.

[0030] Furthermore, when there are no manned missions to be performed in the manned cabin, the control logistics cabin and the recovery cabin independently perform all pending logistics and recovery tasks, and their operating paths are not constrained by the docking time window of the manned cabin.

[0031] A building logistics system, comprising:

[0032] The aforementioned three-compartment integrated circulating logistics elevator;

[0033] A loading device installed on the upper part of the building and connected to an openable and closable interface on the top of the logistics compartment;

[0034] An unloading device located at the bottom of the building and connected to an openable and closable interface at the bottom of the recovery compartment;

[0035] Platform devices installed on each floor are used for the handover of goods or recyclables when the logistics compartment or recycling compartment stops at it.

[0036] A central dispatch control platform is communicatively connected to the elevator, the loading device, the unloading device, and the platform device, and is configured to execute the collaborative dispatch method.

[0037] The above technical solution has the following advantages or technical effects:

[0038] 1. This invention divides the car frame into a logistics compartment, a passenger compartment, and a recycling compartment within a single elevator shaft using fixed partitions, thereby achieving spatial integration of three functions: passenger transport, goods delivery, and waste recycling. This avoids the additional occupation of building common area by multi-shaft solutions and also avoids the hygiene hazards and safety risks of mixed passenger and goods transport in the same car in single-car time-switching solutions.

[0039] 2. This invention connects three compartments to the same main traction drive system, enabling a single traction system to drive all three functional compartments simultaneously. Compared to a solution that sets up independent drive systems for each compartment, this significantly reduces equipment costs and the space occupied at the top of the shaft. Furthermore, by setting up independent lateral opening door systems for each compartment, each compartment can independently perform door opening operations on different floors, providing a physical basis for the collaborative scheduling method.

[0040] 3. This invention prioritizes the operation of the manned cabin as the highest priority benchmark. By dynamically selecting the follow mode or the detach mode based on the relationship between the target floor of the task to be performed and the target floor of the manned cabin, logistics and recovery operations can be performed in parallel using the time window of the manned cabin docking. This transforms the originally idle shaft transportation capacity time into effective working time, achieving optimal timing scheduling under shared traction drive constraints, and significantly improving the overall throughput of the system without reducing the quality of manned service.

[0041] 4. This invention sets feasible conditions for disengagement, compares the time required for the round-trip operation of the logistics compartment or recovery compartment with the estimated docking time of the passenger compartment, and allows disengagement only when the round-trip time is less than the difference between the docking time and the preset buffer time. Furthermore, it incorporates parameters such as the rated speed and acceleration of the elevator and the loading and unloading operation time for precise calculation.

[0042] 5. This invention reduces additional energy consumption by limiting the departure direction of the logistics compartment to a floor higher than the target floor of the manned cabin and the departure direction of the recovery compartment to a floor lower than the target floor of the manned cabin, thus aligning the departure direction with the physical flow of logistics and recovery operations. Furthermore, by setting a multi-task docking sequence planning mechanism, the number of tasks completed is maximized within a limited time window using the optimal path. Finally, by removing the time window constraint when the manned cabin has no tasks, the logistics and recovery compartments can efficiently complete all pending operations, comprehensively improving system energy efficiency, throughput, and equipment utilization.

[0047] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Example 1

[0049] like Figure 1 As shown, a three-compartment integrated circulating logistics elevator is installed in the elevator shaft of a building's core tube. The interior of the car frame is divided by fixed partitions into an upper logistics compartment 1, a middle passenger compartment 2, and a lower recovery compartment 3 arranged vertically in sequence. The three compartments are connected to the same main traction drive system 4, and the traction machine drives the car frame to rise and fall as a whole through steel wire ropes or steel belts, while the three compartments move vertically along the shaft simultaneously.

[0050] Each of the three compartments is equipped with an independent side-opening door system 5. Logistics compartment 1 has a logistics compartment 1 door on its side wall facing the elevator hall or ceiling mezzanine on each floor; passenger compartment 2 has a passenger compartment 2 door on its side wall facing the elevator hall on each floor; and recovery compartment 3 has a recovery compartment 3 door on its side wall facing the elevator hall or ceiling mezzanine on each floor. Each compartment's side-opening door system 5 consists of its own independent door operator and door panel, allowing for independent control of opening and closing.

[0051] The top of the logistics compartment 1 is equipped with an openable and closable interface for docking with the loading device 8 on the upper part of the building. For example... Figure 2 As shown in the illustration, in one specific embodiment, the top openable / closable interface 6 is a top openable / closable door located on the top plate of the logistics compartment 1, driven by an independent gantry crane. A loading device 8 is installed on the roof equipment floor, and its discharge port is equipped with a docking channel 9 corresponding to the position of the top openable / closable door. When the logistics compartment 1 rises to the roof loading position, the top openable / closable door opens, forming a sealed connection with the docking channel 9. The loading device 8 then delivers the cargo box into the logistics compartment 1, completing the loading. After loading is complete, the top openable / closable door closes, and the logistics compartment 1 descends with the car frame to perform the delivery task.

[0052] The bottom of the recovery compartment 3 is equipped with an openable / closable interface for docking with the unloading device 10 located at the bottom of the building. In one specific embodiment, this bottom openable / closable interface 7 is a bottom openable / closable door located on the bottom plate of the recovery compartment 3, driven by an independent gantry crane. The unloading device 10 is located at the bottom of the building, and its receiving port corresponds to the position of the bottom openable / closable door. When the recovery compartment 3 descends to the unloading position, the bottom openable / closable door opens, and the recyclable material inside the recovery compartment 3 falls through the bottom openable / closable door into the receiving port, entering the unloading device 10 to complete the unloading process.

[0053] The side wall of recycling bin 3 is also equipped with a recycling input port, which connects to the output end of a pre-installed recycling channel within the building to receive recyclables. Specifically, recycling risers or recycling channels can be pre-installed on certain floors of the building. Recyclables from each floor are fed into the recycling port and then collected along the recycling channel to a buffer bin. The discharge port of the buffer bin corresponds to the recycling input port of recycling bin 3. When the elevator stops at that floor, the recycling input port connects with the discharge port of the buffer bin, and the recyclables in the buffer bin enter the interior of recycling bin 3 through the recycling input port.

[0054] In this embodiment, the vertical arrangement of the three compartments is as follows: logistics compartment 1 at the top, passenger compartment 2 in the middle, and recovery compartment 3 at the bottom. This arrangement matches the physical flow direction of the building, enabling each compartment to efficiently dock with the loading device 8 at the top of the building, the platform devices on each floor, and the unloading device 10 at the bottom of the building. The top and bottom operable doors are driven by independent door operators, without interfering with each other. Their opening and closing are uniformly controlled by the central dispatch control platform, ensuring that they can only be opened when the elevator is stopped at the corresponding loading or unloading position.

[0055] Example 2

[0056] like Figure 3 As shown, a collaborative scheduling method for a three-compartment integrated circulating logistics elevator based on Embodiment 1 is described. The central scheduling control system obtains the operating status of each compartment and various task requests in real time and executes the collaborative scheduling method.

[0057] The system obtains the next target floor L_p and estimated dwell time T_s for passenger cabin 2. The next target floor L_p is determined by the call command input by passengers through the elevator call panel in the elevator lobby. The estimated dwell time T_s is calculated based on the estimated number of passengers on that floor, door opening and closing times, and passenger entry and exit times. The preset safety buffer time ΔT is determined based on the system's control accuracy and operational stability requirements.

[0058] The system prioritizes the operation of manned cabin 2 and controls logistics cabin 1 and recovery cabin 3 to operate independently based on the real-time status of manned cabin 2.

[0059] When there is a pending task in the logistics module 1 or the recovery module 3 that is the same as the next target floor L_p of the manned module 2, the system controls the logistics module 1 or the recovery module 3 to enter the following mode. In the following mode, the logistics module 1 or the recovery module 3 runs synchronously with the manned module 2 to its target floor L_p, and performs cargo delivery or receiving of recyclables.

[0060] When there is a pending task in the logistics module 1 or the recovery module 3 with a target floor L_d different from the next target floor L_p of the manned module 2 and detachment is feasible, the system controls the logistics module 1 or the recovery module 3 to enter the detachment mode. In the detachment mode, the logistics module 1 or the recovery module 3 runs independently of the manned module 2 during the stop of the manned module 2 to the target floor L_d to perform operations, and returns to the same vertical position as the manned module 2 before the end of the stop of the manned module 2. Detachment means that the operation plan of the logistics module 1 or the recovery module 3 is decoupled from the stop plan of the manned module 2 in time, that is, the logistics module 1 or the recovery module 3 continues to run upward or downward during the stop of the manned module 2, rather than physically detaching from the car frame. In the detachment mode, the target floor that the logistics module 1 runs independently to is higher than the target floor of the manned module 2, that is, L_d > L_p; the target floor that the recovery module 3 runs independently to is lower than the target floor of the manned module 2, that is, L_d < L_p.

[0061] Detachment is feasible means that the total time T_return required for the logistics module 1 or the recovery module 3 to run from the current position to the target floor L_d to complete the operation and return to the position L_p where the manned module 2 is located is less than the difference between the estimated stop duration T_s and the preset safety buffer time ΔT, that is, T_return < T_s - ΔT. T_return at least includes the movement time of the detachment module from the current position to the target floor, the loading and unloading operation time at the target floor, and the time to return from the target floor to the position where the manned module 2 is located.

[0062] The feasibility of detachment is determined through the following steps: According to the current position of the logistics module 1 or the recovery module 3, the target floor L_d to be operated, the rated speed and acceleration of the elevator, and the estimated stop duration T_s of the manned module 2, calculate the total time T_return required to complete the operation and return to the same vertical position as the manned module 2 after detachment; if T_return is less than the difference between T_s and ΔT, it is determined that detachment is feasible; otherwise, it is determined that detachment is not feasible. If it is determined that detachment is not feasible, control the logistics module 1 or the recovery module 3 to enter the following mode or standby state.

[0063] In the detachment mode, when there are multiple pending tasks with target floors different from L_p, the system controls the logistics module 1 or the recovery module 3 to stop at each target floor in sequence to perform operations. The stop sequence is planned and determined according to the relative position relationship between each target floor and the target floor L_p of the manned module 2 and the estimated stop duration T_s.

[0064] If, during the disengagement process, logistics module 1 or recovery module 3 fails to return to the same vertical position as manned module 2 before it finishes docking due to equipment failure or operation timeout, the system controls logistics module 1 or recovery module 3 to suspend the current operation and return to the location L_p of manned module 2. If returning is not feasible, the system controls it to dock at the current floor for safety and replans the subsequent operation path according to the next target floor of manned module 2, so that logistics module 1 or recovery module 3 can re-coordinate with manned module 2 in the subsequent docking cycle.

[0065] When there are no manned missions to be executed in manned module 2, the system controls logistics module 1 and recovery module 3 to independently execute all pending logistics and recovery tasks, and their operating paths are not constrained by the docking time window of manned module 2. When a new manned mission occurs, the system immediately switches back to normal scheduling mode, with the operation of manned module 2 as the highest priority benchmark.

[0066] Example 3

[0067] like Figure 4 As shown, a building logistics system includes the three-compartment integrated circulating logistics elevator described in Embodiment 1 above, a loading device 8 installed on the upper part of the building, an unloading device 10 installed on the lower part of the building, platform devices installed on each floor, and a central dispatch and control platform.

[0068] The loading device 8 is located on the upper part of the building and docks with the openable / closable interface on the top of the logistics compartment 1. In one specific embodiment, the loading device 8 is an automated sorting system, including a sorting conveyor belt, a discharge port, and a docking channel 9. Goods from the external logistics system are sorted and then enter the interior of the logistics compartment 1 through the discharge port and docking channel 9 via the openable / closable interface 6 on the top.

[0069] The unloading device 10 is located at the bottom of the building and connects to the openable / closable interface at the bottom of the recycling bin 3. In one specific embodiment, the unloading device 10 is an underground recycling collection station, including a receiving port and a conveying device. The recyclables in the recycling bin 3 enter the unloading device 10 through the bottom openable / closable interface 7 and the receiving port.

[0070] Platform devices are installed on each floor to facilitate the transfer of goods or recyclables when the elevator stops at logistics compartment 1 or recycling compartment 3. In one specific embodiment, the platform device includes a shuttle or conveyor belt installed in the mezzanine of the elevator lobby ceiling. When the elevator stops at a floor, the door of logistics compartment 1 opens, and the shuttle of the platform device extends into the interior of logistics compartment 1 to retrieve the cargo box and transport it to the floor terminal distribution cabinet, or to load goods to be sent into logistics compartment 1. The recycling operation is similar.

[0071] The central dispatching control platform is communicatively connected to the elevator, the loading device 8, the unloading device 10, and the platform device, and is configured to execute the collaborative dispatching method described in Embodiment 2. The central dispatching control platform performs data interaction with the control systems of each device through a communication network, real-time obtains the operating status of each device, and uniformly schedules all resources.

[0072] The working process of the system will be described below in conjunction with a specific application scenario.

[0073] On the building roof equipment layer, the loading device 8 sorts the goods from the logistics system according to the target floor. The logistics cabin 1 rises to the roof loading position, the top opening and closing door opens, docks with the docking channel 9 of the loading device 8, and the cargo box enters the interior of the logistics cabin 1. After loading, the top opening and closing door closes.

[0074] The central dispatching control platform obtains the next target floor L_p and the estimated docking duration T_s of the manned cabin 2. When the logistics cabin 1 has a pending task identical to L_p, the system controls the logistics cabin 1 to enter the following mode and synchronously operate with the manned cabin 2 to L_p. After the elevator docks, the door of the manned cabin 2 opens for passengers to enter and exit, and at the same time, the door of the logistics cabin 1 opens to complete the cargo transfer with the platform device.

[0075] During the docking of the manned cabin 2, if the logistics cabin 1 still has a pending task with a target floor L_d different from L_p, and T_return < T_s - ΔT, the system controls the logistics cabin 1 to enter the detachment mode. The logistics cabin 1 independently ascends to L_d to perform the distribution task during the continued docking of the manned cabin 2, and returns to be at the same vertical position as the manned cabin 2 after completion.

[0076] The recycling operation process is similar. The recyclables from each floor are collected through the recycling channel into the buffer bin. When the elevator docks at the floor where the buffer bin is located, the recycling input port of the recycling cabin 3 is docked with the discharge port of the buffer bin, and the recyclables enter the interior of the recycling cabin 3. When the manned cabin 2 docks at a higher floor, the recycling cabin 3 can detach and descend to a lower floor to perform the recycling operation and return. After the recycling cabin 3 is full, it descends with the car frame to the unloading position, and the bottom opening and closing interface 7 opens to complete the unloading.

[0077] This system realizes the parallel operation of three functions: manned transportation, cargo distribution, and waste recycling in a single elevator shaft. Under the constraint of sharing the traction power, with the manned cabin 2 as the highest priority benchmark, it dynamically utilizes the time window of the docking of the manned cabin 2 to perform logistics and recycling operations, greatly improving the time utilization rate of the shaft transportation capacity.

[0078] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
