Description

Technical Field

[0001] The present invention relates to the technical field of elevator energy saving, and in particular to a dispatching method and a dispatching system for an energy storage elevator. Background Art

[0002] Currently, the energy-saving method for elevators is to use energy storage elevators, which are equipped with energy storage and power-saving devices. Energy feedback technology is used to feed back the excess electrical energy generated during the operation of the elevator into the energy storage device of the energy storage and power-saving device. For example: when the elevator is lightly loaded upward or heavily loaded downward, the traction motor is in a power generation state, generating electricity; traditional elevator systems will consume this part of the electricity in the form of heat energy (i.e., energy consumption resistor consumption), while the energy storage elevator's energy feedback system stores the electricity through the energy storage and power-saving device for use when the elevator is lightly loaded downward and heavily loaded upward (the traction motor is in a power consumption state), or to power the elevator lighting, ventilation and other equipment, thereby achieving the effect of recycling energy and saving electricity.

[0003] However, a common dispatching method for energy storage elevators is to dispatch an elevator to the nearest floor when a user calls from outside the building. When there are no calls, the elevator is automatically dispatched back to an intermediate floor or the ground floor. This dispatching method results in numerous energy-wasting scenarios, preventing the elevator from achieving optimal energy savings.

[0004] For example, when a user registers an outbound call at the elevator lobby on the 3rd floor, there are two unloaded elevators, A and B, on the 5th and 1st floors, respectively. The energy storage and power-saving devices in both elevators are fully charged, and both elevators have the same distance to reach the 3rd floor. If elevator B is dispatched from the 1st floor to the 3rd floor, the energy storage and power-saving device will charge, but at this point, the charge will be fully charged and dissipated through the energy-dissipating resistor, resulting in zero energy savings and no energy saving effect. At this time, if elevator A is dispatched from the 5th floor to the 3rd floor, the energy storage and power-saving device will discharge the energy to the elevator, reducing energy consumption and achieving energy saving. Summary of the Invention

[0005] In view of the above-mentioned defects, the purpose of the present invention is to propose a dispatching method and dispatching system for energy storage elevators, which solves the problem that energy storage elevators cannot achieve the optimal energy-saving effect when dispatched according to the proximity principle of traditional elevators.

[0006] To achieve this object, the present invention adopts the following technical solutions:

[0007] A method for dispatching an energy storage elevator comprises the following steps:

[0008] A1: When a user makes an outbound call, the proximity priority of each elevator is determined based on the distance between each elevator and the called floor. The closer the distance between the elevator and the called floor, the higher the proximity priority.

[0009] A2: Determine whether each elevator is in a power-consuming state or a power-generating state when traveling to a called floor. Elevators in a power-consuming state are ranked by power consumption to determine the power consumption level of each elevator. The higher the power consumption, the higher the power consumption level. Furthermore, elevators in a power-generating state are ranked by power generation to determine the power generation level of each elevator. The higher the power generation, the higher the power generation level.

[0010] A3: Determine the energy storage capacity D of each elevator. When D ≤ 90%, the dispatch priority of each elevator is calculated by adding the proximity priority and the power generation weight. When D > 90%, the dispatch priority of each elevator is calculated by adding the proximity priority and the power consumption weight.

[0011] A4: Select the elevator with the highest dispatch priority and go to the called floor.

[0012] Furthermore, in step A1: the proximity priority is: A=H-|h1-h2|; wherein H is the total number of floors, h1 is the floor where the elevator is located, and h2 is the called floor.

[0013] Furthermore, step A2 is as follows: based on the called floor and the total load weight, total counterweight weight, and floor of each elevator, the energy-saving priority of each elevator is calculated: B = (m1-m2)(h1-h2); wherein m1 is the total load weight of the elevator, m2 is the total counterweight weight of the elevator, h1 is the floor where the elevator is located, and h2 is the called floor;

[0014] When B ≥ 0, the energy-saving priority B is used as the power generation level;

[0015] When B<0, the energy saving priority level B is used as the power consumption level.

[0016] Furthermore, the step A3 is:

[0017] When D≤90%, the dispatch priority of each elevator is: ;

[0018] When D>90%, the dispatch priority of each elevator is: ;

[0019] Where k1 and k2 are weight coefficients, and the sum of k1 and k2 is equal to 1;

[0020] Then in step A4: select the elevator with the larger dispatch priority value to go to the called floor.

[0021] Furthermore, in step A3:

[0022] When D≤90%, a gradient charging demand coefficient S is set, and the charging demand coefficient S is assigned according to the current energy storage capacity D of each elevator; the smaller the energy storage capacity D of the elevator, the larger the charging demand coefficient S assigned;

[0023] The dispatch priority of each elevator is: ;

[0024] Where k1 and k2 are weight coefficients, and the sum of k1 and k2 is equal to 1;

[0025] Then in step A4: select the elevator with the larger dispatch priority value to go to the called floor.

[0026] Furthermore, the method further includes step A5: the elevator that has completed the transport task is idle on the transport floor;

[0027] The step A1 further includes: when a user makes an outbound call, only elevators in an idle state are included in the dispatching sequence.

[0028] Furthermore, the step A1 further includes: when there are multiple users making outbound calls on different floors, selecting the floor where the earliest outbound calling user is located as the calling floor.

[0029] Furthermore, in step A3, the charging demand coefficient S is graded in a gradient at every 10% of the energy storage capacity D, and the charging demand coefficient S of each grade is in a linear relationship.

[0030] Furthermore, in step A4: when there are elevators with the same dispatch priority value, one of the elevators is randomly selected to go to the called floor.

[0031] A dispatching system for an energy storage elevator, applying the above-mentioned dispatching method for an energy storage elevator, comprises an elevator monitoring system, an elevator control system, an elevator dispatching cloud, and a plurality of energy storage elevators; the power management systems of the energy storage elevators respectively interact with the elevator dispatching cloud for data, and the elevator dispatching cloud obtains energy storage information of each energy storage elevator through the power management system of each energy storage elevator;

[0032] The energy storage elevators respectively interact with the elevator monitoring system for data exchange, and the elevator monitoring system interacts with the elevator dispatching cloud for data exchange, and the elevator dispatching cloud obtains the operating information of all the energy storage elevators through the elevator monitoring system;

[0033] The energy storage elevators interact with the elevator control system data respectively, the elevator control system interacts with the elevator dispatching cloud data, and the elevator dispatching cloud dispatches all the energy storage elevators through the elevator control system.

[0034] The technical solution provided by the present invention can achieve the following beneficial effects: The principle of proximity-based dispatching in traditional elevators is summarized as proximity-based priority; In order to fully utilize the energy-saving effect of energy storage elevators, each elevator uses a dual-state decision-making mechanism based on power consumption and power generation status, and dynamically adjusts the energy storage capacity D of each elevator.

[0035] (1) Solve the pain point of energy waste: When the energy storage is close to full charge (based on the existing battery performance, the last 10% of the power is usually difficult to fully charge, and you can choose to give up charging) or is fully charged (D>90%), priority is given to dispatching elevators in power-consuming state to avoid the power consumption of elevators in power-generating state due to energy overflow.

[0036] (2) Improve energy recovery rate: When energy storage is insufficient (D≤90%), priority is given to dispatching elevators in power generation state to maximize energy recovery efficiency.

[0037] To summarize, in order to break the limitations of traditional scheduling, the "optimal energy-saving scheduling method for energy storage elevators" and the "proximity principle" are weighted and integrated (the weight distribution of the two factors can be determined based on the actual operating results), upgrading from single distance optimization to energy-distance dual-dimensional optimization. This can achieve the optimal energy-saving effect of energy storage elevators while taking into account proximity scheduling. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following combination Figures 1 to 2 , describing a dispatching method and dispatching system of an energy storage elevator in an embodiment of the present invention.

[0045] A method for dispatching an energy storage elevator comprises the following steps:

[0046] A1: When a user makes an outbound call, the proximity priority of each elevator is determined based on the distance between each elevator and the called floor. The closer the distance between the elevator and the called floor, the higher the proximity priority.

[0047] A2: Determine whether each elevator is in a power-consuming state or a power-generating state when traveling to a called floor. Elevators in a power-consuming state are ranked by power consumption to determine the power consumption level of each elevator. The higher the power consumption, the higher the power consumption level. Furthermore, elevators in a power-generating state are ranked by power generation to determine the power generation level of each elevator. The higher the power generation, the higher the power generation level.

[0048] A3: Determine the energy storage capacity D of each elevator. When D ≤ 90%, the dispatch priority of each elevator is calculated by adding the proximity priority and the power generation weight. When D > 90%, the dispatch priority of each elevator is calculated by adding the proximity priority and the power consumption weight.

[0049] A4: Select the elevator with the highest dispatch priority and go to the called floor.

[0050] The present invention proposes a preferred embodiment of a dispatching method for an energy storage elevator, as follows: Figure 1 As shown in the figure, the principle of proximity scheduling for traditional elevators is summarized as proximity priority. To fully utilize the energy-saving effect of energy storage elevators, each elevator uses a dual-state decision-making mechanism based on power consumption / generation status, and dynamically adjusts the energy storage capacity D of the elevator:

[0051] (1) Solve the pain point of energy waste: When the energy storage is close to full charge (based on the existing battery performance, the last 10% of the power is usually difficult to fully charge, and you can choose to give up charging) or is fully charged (D>90%), priority is given to dispatching elevators in power-consuming state to avoid the power consumption of elevators in power-generating state due to energy overflow.

[0052] (2) Improve energy recovery rate: When energy storage is insufficient (D≤90%), priority is given to dispatching elevators in power generation state to maximize energy recovery efficiency.

[0053] To summarize, in order to break the limitations of traditional scheduling, the "optimal energy-saving scheduling method for energy storage elevators" and the "proximity principle" are weighted and integrated (the weight distribution of the two factors can be determined based on the actual operating results), upgrading from single distance optimization to energy-distance dual-dimensional optimization. This can achieve the optimal energy-saving effect of energy storage elevators while taking into account proximity scheduling.

[0054] It should be noted that the data of the energy storage capacity D can be obtained from the energy storage information of the power management system in each energy storage elevator.

[0055] Furthermore, in step A1: the nearest priority is: A=H-|h1-h2|; wherein H is the total number of floors, h1 is the floor where the elevator is located, and h2 is the called floor.

[0056] In this embodiment, the closer the distance between an elevator and the called floor, the higher the proximity priority. The formula A=H - |h1 - h2| is designed, where |h1 - h2| corresponds to distance. A larger value represents a higher proximity priority. This ensures that proximity priority increases with distance, achieving modularization of factors and facilitating (or compatibility with) subsequent weighted calculations of dispatch priority. More importantly, the three data points, H, h1, and h2, can all be obtained from the operating information of each elevator. Once aggregated, a single formula can be used to quickly derive representative results.

[0057] Furthermore, step A2 is: based on the called floor and the total load weight, total counterweight weight, and the floor of each elevator, the energy-saving priority of each elevator is calculated: B = (m1-m2)(h1-h2); wherein m1 is the total load weight of the elevator, m2 is the total counterweight weight of the elevator, h1 is the floor where the elevator is located, and h2 is the called floor;

[0058] When B ≥ 0, the energy-saving priority B is used as the power generation level;

[0059] When B<0, the energy saving priority level B is used as the power consumption level.

[0060] In this embodiment, based on the modularization of the formula in step A1, in order to realize that one formula replaces all the judgments in step A2, the power generation level and the power consumption level are integrated into the energy-saving priority level to reflect that the greater the power consumption, the higher the power consumption level, and the greater the power generation, the higher the power generation level. Therefore, the power generation level and the power consumption level are reflected in the energy-saving priority formula: B = (m1-m2)(h1-h2). The principle of this formula is equivalent to the potential energy conversion formula, where (m1-m2) reflects whether the elevator is heavily loaded or lightly loaded (dispatched elevators are actually all lightly loaded), and (h1-h2) reflects the distance the elevator needs to travel to the outbound call floor. After multiplying the two, when the elevator is in the power generation state with a light load ascending or a heavy load descending, the energy-saving priority level B is a positive number (B≥0), and the greater the power generation, the greater the value of the energy-saving priority level B; when the elevator is in the power consumption state with a light load descending or a heavy load ascending, the energy-saving priority level B is a negative number (B<0), and the greater the power consumption, the smaller the value of the energy-saving priority level B.

[0061] In other words, this formula modularizes step A2, expressing both energy-saving states with a single formula. This reflects the entire content of the original step A2, reduces the number of branching decisions, and facilitates (or is compatible with) subsequent weighted scheduling priority calculations. More importantly, data such as m1, m2, h1, and h2 can all be obtained from the operating information of each elevator.

[0062] Furthermore, step A3 is:

[0063] When D≤90%, the dispatch priority of each elevator is: ;

[0064] When D>90%, the dispatch priority of each elevator is: ;

[0065] Where k1 and k2 are weight coefficients, and the sum of k1 and k2 is equal to 1;

[0066] Then in step A4: select the elevator with the larger dispatch priority value to go to the called floor.

[0067] In this embodiment, formula modularization is implemented based on both steps A1 and A2, and the calculation results of both are in an increasing relationship; therefore, the corresponding formula of step A3 is modularized. After the energy storage capacity D is determined, the calculation results of the two can be directly used for weight addition to obtain the scheduling priority level that is also in an increasing relationship, thereby selecting the optimal scheduling elevator.

[0068] It should be noted that when using energy-saving priority B, to make it reflect the increasing relationship of power consumption (when D>90%), a negative sign is added, that is, -B (equivalent to the relationship is reversed). This satisfies the logic that the higher the power consumption, the more it should be selected. In this case, the energy-saving priority B of the elevator in the power-generating state is always lower than the energy-saving priority B of the elevator in the power-consuming state. When D≤90%, the energy-saving priority B is applied in the same way, without the minus sign, and can be directly added. This will not be further explained here.

[0069] Furthermore, in step A3:

[0070] When D≤90%, a gradient charging demand coefficient S is set, and the charging demand coefficient S is assigned according to the current energy storage capacity D of each elevator; the smaller the energy storage capacity D of the elevator, the larger the charging demand coefficient S assigned;

[0071] The dispatch priority of each elevator is: ;

[0072] Where k1 and k2 are weight coefficients, and the sum of k1 and k2 is equal to 1;

[0073] Then in step A4: select the elevator with the larger dispatch priority value to go to the called floor.

[0074] In this embodiment, when D ≤ 90%, considering that the charging urgency of each elevator should be different depending on the energy storage capacity D, it is preferred to take this factor into consideration and charge elevators with less energy storage first. Since the charging urgency factor should be attributed to the energy storage system, it is preferred to give a certain weight to the energy saving priority B. Then the scheduling priority formula is modified as follows: .

[0075] Furthermore, the method further includes step A5: the elevator that has completed the transport task is idle on the transport floor;

[0076] Step A1 also includes: when a user makes an outbound call, only elevators in an idle state are included in the dispatching sequence.

[0077] In this embodiment, according to traditional elevator control logic, when the elevator completes its transportation mission, it will return to the middle floor or the first floor and wait for the next user outbound call dispatch; this will cause the energy storage elevator to enter an ineffective energy-saving state of continuing to generate electricity when fully charged, or an energy-unstable state of continuing to consume energy storage power / mains electricity when the energy storage power is insufficient; therefore, the preferred setting is: the elevator that has completed its transportation mission is idle on the transportation floor and waits in place for the next dispatch, ensuring that elevator dispatch is always effective and energy-saving.

[0078] In addition, considering that some elevators are being dispatched or are carrying out transportation work, the elevator working conditions are complicated. In order to facilitate the elevator dispatching system to accurately identify which elevators can be dispatched, the idle state is selected as the elevator dispatchable sign.

[0079] Furthermore, step A1 further includes: when there are multiple users making outbound calls on different floors, selecting the floor where the earliest outbound calling user is located as the calling floor.

[0080] In this embodiment, when there are multiple users making outbound calls on different floors, if the elevator dispatch system dispatches elevators to all called floors at the same time, the dispatching priorities of the same elevator facing different called floors will overlap, causing a dispatching conflict. Therefore, the dispatching principle is preferably based on chronological order. After answering a user's outbound call request, the elevator is dispatched to the back (at this time, the elevator is not in an idle state and will not be dispatched, so there is no conflict), and then answering the next user.

[0081] Furthermore, in step A3: the charging demand coefficient S is graded in a gradient at every 10% of the energy storage capacity D, and the charging demand coefficient S of each level is in a linear relationship.

[0082] In this embodiment, when D≤90%, the dispatch priority of each elevator is: If the charging demand coefficient S is set to an exponential or other regular pattern, the dispatch priority C will be determined by the charging demand coefficient S, which fails to reflect that the dispatch priority C is the result of a comprehensive consideration of three aspects: elevator proximity, elevator energy efficiency, and elevator energy storage charging needs. Therefore, the charging demand coefficient S should be graded at intervals of 10% of the energy storage capacity D, and the charging demand coefficient S at each level should be linearly related, so that the charging demand coefficient S's evaluation of the elevator energy storage charging demand increases in a balanced manner. An example of the charging demand coefficient S setting is shown in Table 1 below.

[0083]

[0084] Furthermore, in step A4: when there are elevators with the same dispatch priority value, one of the elevators is randomly selected to go to the called floor.

[0085] In this embodiment, when there are elevators with the same dispatch priority value, in addition to the same calculation, it is also possible that the two elevators are located on the same floor, energy storage capacity D and other factors are the same. At this time, other factors are judged in turn to select the elevator to go to, and there may still be a conflict. Therefore, it is preferred to randomly select one of the elevators to go to the called floor.

[0086] A dispatching system for an energy storage elevator, applying the above-mentioned dispatching method for an energy storage elevator, comprises an elevator monitoring system 2, an elevator control system 3, an elevator dispatching cloud 4, and a plurality of energy storage elevators 1; the power management systems of the energy storage elevators 1 respectively interact with the elevator dispatching cloud 4 for data, and the elevator dispatching cloud 4 obtains energy storage information of each energy storage elevator 1 through the power management system of each energy storage elevator 1;

[0087] The energy storage elevator 1 exchanges data with the elevator monitoring system 2, and the elevator monitoring system 2 exchanges data with the elevator dispatch cloud 4. The elevator dispatch cloud 4 obtains the operating information of all energy storage elevators 1 through the elevator monitoring system 2;

[0088] The energy storage elevators 1 interact with the elevator control system 3 for data exchange, and the elevator control system 3 interacts with the elevator dispatch cloud 4 for data exchange. The elevator dispatch cloud 4 dispatches all energy storage elevators 1 through the elevator control system 3 .

[0089] In this embodiment, a preferred embodiment of a dispatching system for an energy storage elevator is also proposed. Figure 2 As shown, the elevator dispatch cloud 4 (i.e., cloud platform) obtains energy storage information (such as the power of the energy storage device and the operating status of the energy storage system) through data interaction (wired, wireless, or network channels) through the power management system (such as the BMS power management system) of the energy storage system in the energy storage elevator 1, and obtains operating information (such as the stop floor, operating direction, working status, fault status, etc.) through the elevator monitoring system 2 (such as the BA signal real-time elevator monitoring system and the elevator's own control panel feedback), thereby obtaining the data basis required for the above-mentioned dispatching method. Based on this data, the elevator dispatch cloud 4 selects the energy storage elevator 1 that meets the energy-saving requirements according to the above-mentioned dispatching method, and dispatches it through the elevator control system 3.
