Elevator group management method and system

Abstract

The present invention discloses an elevator group management method and system, which controls the stopping of a stop elevator about to stop at a separated floor so that the stop elevator satisfies a time separation condition and / or a position separation condition when stopping at the separated floor. This achieves time separation and / or position separation for waiting passengers on the separated floor who need to board different destination elevators, allowing waiting passengers on the separated floor to correctly board their corresponding destination elevators. The time separation condition refers to the time interval between the stop periods of any two stop elevators while stopping at the separated floor being greater than a time threshold; the position separation condition refers to the position distance between the stop positions of any two stop elevators while stopping at the separated floor being greater than a distance threshold. The present invention can effectively prevent passengers waiting at the separated floor from entering the wrong destination elevator, thereby improving the passenger experience, increasing elevator operating efficiency, and reducing elevator power consumption.

Description

Technical Field

[0001] The present invention relates to the field of elevators, and in particular to an elevator group management method and system. Background Art

[0002] For situations where multiple elevators are deployed at the same time, an elevator group management system is usually set up to optimize the deployment of elevators, thereby improving the operating efficiency of the elevators and shortening the waiting time of passengers.

[0003] Furthermore, on certain floors, such as high-traffic floors, passengers traveling in different directions often wait for the elevator at the same time. For floors equipped with destination floor registration devices, passengers traveling to different floors often wait for the elevator at the same time. In this case, if multiple elevators arrive at the same floor simultaneously, especially if the distance between the elevators arriving at the floor is small or the elevators arrive at the same floor at roughly the same time, passengers often board the wrong elevator. To prevent this from affecting passenger travel and elevator efficiency, appropriate measures must be taken to prevent this from happening.

[0004] Therefore, how to prevent passengers from taking the wrong elevator by taking appropriate measures has become a technical problem to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an elevator group management method and system, which can solve the problem that passengers often take the wrong elevator on floors with large passenger flow.

[0006] To solve the above-mentioned problem, the present invention provides an elevator group management method, which controls the stopping of a stop elevator that is about to stop at a separated floor at the separated floor, so that the stop elevator satisfies at least one of a time separation condition and a position separation condition when stopping at the separated floor. This achieves time separation and / or position separation for waiting passengers on the separated floor who need to board different destination elevators, so that waiting passengers on the separated floor can correctly board their corresponding destination elevators.

[0007] The separated floor refers to a floor where there are waiting passengers who need to take different destination elevators at the same time and who need to be separated to avoid the waiting passengers from taking non-destination elevators; the time separation condition refers to the time interval between the stop periods of any two stopping elevators during their stop at the separated floor is greater than a time threshold; the position separation condition refers to the position distance between the stop positions of any two stopping elevators during their stop at the separated floor is greater than a distance threshold.

[0008] Furthermore, the group management method determines whether a specific elevator group exists based on elevator operation information and elevator request signals from the waiting passengers, and when the determination result is that the specific elevator group exists, controls at least one specific elevator in the specific elevator group to stop at the separated floors so that the specific elevators in the specific elevator group meet the time separation condition and / or the position separation condition; the specific elevator group is composed of two stopping elevators that neither meet the time separation condition nor the position separation condition, and the specific elevators are the stopping elevators that constitute the specific elevator group.

[0009] Further, controlling the specific elevator to stop at the separated floor includes controlling at least one of whether the specific elevator stops at the separated floor and controlling a stopping period during which the specific elevator stops at the separated floor.

[0010] Furthermore, the group management method changes the elevator request signal assigned to the first specific elevator in the specific elevator group and having the separated floor as the departure floor, so that the first specific elevator does not stop at the separated floor.

[0011] Furthermore, the group management method allocates the elevator request signal originally allocated to the first specific elevator and having the separated floor as the departure floor to other elevators so that the first specific elevator does not stop at the separated floor.

[0012] Furthermore, when the following conditions are met, the group management method allocates all boarding request signals originally allocated to the first specific elevator and having the separated floor as a departure floor to a second specific elevator in the specific elevator group so that the first specific elevator does not stop at the separated floor:

[0013] Condition 1: The first specific elevator and the second specific elevator have the same running direction;

[0014] Condition 2: The destination floor of the passengers in the car of the first specific elevator does not include the separated floor;

[0015] Condition 3: The remaining resources of the second specific elevator are greater than the required resources of the waiting passengers corresponding to the newly allocated elevator request signal.

[0016] Furthermore, when the following conditions are met, the group management method allocates all boarding request signals originally assigned to the first specific elevator and having the separated floor as a departure floor to other elevators outside the specific elevator group where the first specific elevator is located, so that the first specific elevator does not stop at the separated floor:

[0017] Condition A: There is at least one other elevator that runs in the same direction as the first specific elevator and whose remaining resources are not less than the required resources of all waiting passengers corresponding to the newly allocated elevator request signals;

[0018] Condition B: the destination floor of the passengers in the car of the first specific elevator does not include the separated floor;

[0019] Condition C: the other elevators meet the position separation condition and / or the time separation condition after receiving the newly added elevator request signal.

[0020] Further, controlling the stop period of the specific elevator during the stop at the separated floor includes controlling at least one of a start time, a stop duration, and an end time of the stop period.

[0021] Furthermore, the group management method controls at least one of the two specific elevators of the specific elevator group to meet the time separation condition at the start time of the stop period during the stop at the separated floor.

[0022] Furthermore, the group management method changes the starting time of the stop period of the specific elevator during its stop at the separated floor by controlling an action performed before the specific elevator arrives at the separated floor.

[0023] Furthermore, the group management method changes the stop duration and / or end time of the stop period of the specific elevator that has arrived at the separated floor by controlling the execution action of the specific elevator that has arrived at the separated floor during the stop at the separated floor.

[0024] Furthermore, the group management method changes the moving time required for the first specific elevator to move from its current position to the separated floor by changing at least one of the moving speed of the first specific elevator in the specific elevator group toward the separated floor, the number of floors to be stopped between the current position and the separated floor, and the duration of the stop at the floors to be stopped between the current position and the separated floor, thereby changing the starting time of the stop period of the first specific elevator during its stop at the separated floor.

[0025] Furthermore, the group management method changes the number of floors to be stopped between the current position and the separated floor of the first specific elevator by changing the elevator request signal assigned to the first specific elevator with the floor between the current position and the separated floor as the departure floor.

[0026] Furthermore, the group management method changes the number of floors to be stopped by the first specific elevator between its current position and the separated floor by changing the correspondence between the first specific elevator and the elevator request signal with the floor between the separated floor and the current position of the first specific elevator as the departure floor.

[0027] Furthermore, when the following conditions are met, the group management method reallocates the boarding request signal originally assigned to the first specific elevator, which has an intermediate floor between the partition floor and the current position of the first specific elevator as a departure floor, to another substitute elevator other than the specific elevator group in which the first specific elevator is located:

[0028] Condition a: The first specific elevator is assigned the boarding request signal with the intermediate floor between the partition floor and the current position of the first specific elevator as the departure floor, and the destination floor of the first specific elevator does not include the intermediate floor;

[0029] Condition b: After the boarding request signal with the middle floor between the separated floor and the current position of the first specific elevator as the departure floor is reallocated, the time interval between the stopping periods of two specific elevators in the specific elevator group to which the first specific elevator originally corresponds, during which the two specific elevators stop at the separated floor, is greater than the time threshold;

[0030] Condition c: There is at least one alternative elevator that can respond to the reallocated elevator request signal and has the same running direction as the first specific elevator;

[0031] Condition d: If the destination floor of the replacement elevator or the destination floor of the reallocated elevator request signal includes the separated floor, the replacement elevator and any other elevator shall satisfy the time separation condition and / or the position separation condition at the separated floor.

[0032] Furthermore, when the following conditions are met, the group management method reallocates the boarding request signal originally assigned to elevators other than the specific elevator group, which has a floor between the intermediate floor and the current position of the first specific elevator in the specific elevator group as the departure floor, to the first specific elevator, thereby changing the waiting floor for the specific elevator to be located between its current position and the intermediate floor:

[0033] Condition 1: There is at least one elevator other than the specific elevator group and running in the same direction as the first specific elevator, and the elevator request signal is assigned to a floor between the intervening floor and the current position of the first specific elevator as the departure floor;

[0034] Condition 2: After the boarding request signal with the floor between the separating floor and the current position of the first specific elevator as the departure floor is reallocated to the first specific elevator of the specific elevator group, the time interval between the stopping periods of the two specific elevators constituting the specific elevator group while stopping at the separating floor is greater than the time threshold;

[0035] Condition 3: After all the elevator request signals with the floors between the partition floor and the current position of the first specific elevator as departure floors are reallocated, the other elevator will not form a specific elevator group with the remaining elevators.

[0036] Furthermore, the group management method changes the intermediate waiting floor of at least one specific elevator in the specific elevator group by transferring the elevator request signal with the floor between the separated floor and the current position of the first specific elevator as the departure floor from one specific elevator in the specific elevator group to another specific elevator.

[0037] Furthermore, the group management method changes the waiting floors of the first specific elevator by transferring all the elevator request signals originally assigned to the first specific elevator of the specific elevator group and corresponding to at least one departure floor to the second specific elevator of the specific elevator group, and also changes the waiting floors of the second specific elevator at the same time when the waiting floors of the second specific elevator do not include the departure floor of the reallocated elevator request signal.

[0038] Furthermore, when at least one of the waiting-to-stop floors of the first specific elevator constituting the specific elevator group does not belong to the waiting-to-stop floors of the second specific elevator constituting the specific elevator group, the group management method transfers part or all of the elevator request signals corresponding to the waiting-to-stop floors belonging to the waiting-to-stop floors of the first specific elevator but not belonging to the waiting-to-stop floors of the second specific elevator from the first specific elevator to the second specific elevator, thereby changing the waiting-to-stop floors of the second specific elevator.

[0039] Furthermore, when all elevator request signals corresponding to a certain waiting-to-stop floor that belongs to the first specific elevator but does not belong to the waiting-to-stop floor of the second specific elevator are transferred to the second specific elevator, the waiting-to-stop floor of the first specific elevator is changed at the same time.

[0040] Furthermore, the method comprises the following steps:

[0041] Step S1, obtaining the elevator operation information and the elevator request signal of the waiting passenger;

[0042] Step S2: enumerate all possible elevator groups consisting of any two elevators;

[0043] Step S3, calculating the time interval between the stop periods of the two elevators corresponding to each possible elevator group during their stop at the separated floors and the horizontal distance between the stop positions at the separated floors according to the elevator operation information and the elevator request signal;

[0044] Step S4: Determine whether the specific elevator group exists based on the time interval and the horizontal distance. If yes, proceed to step S5; otherwise, end.

[0045] Step S5: Controlling whether at least one of the specific elevators stops at the separated floor and / or controlling the stopping period of at least one of the specific elevators during stopping at the separated floor, so that the specific elevators in the specific elevator group meet the time separation condition and / or the position separation condition.

[0046] Furthermore, the method comprises the following steps:

[0047] Step S1, obtaining the elevator operation information and the elevator user's elevator request signal;

[0048] Step S2: enumerate all possible elevator groups consisting of any two elevators;

[0049] Step S3, calculating the time interval between the stop periods of two elevators corresponding to each possible elevator group during the stop period at the separated floors according to the elevator operation information and the elevator request signal;

[0050] Step S4: Select a possible elevator group whose time interval is less than the time threshold from all possible elevator groups as a pending possible elevator group;

[0051] Step S5: Calculate the horizontal distance of the pending possible elevator group using the parking positions of the elevators in the pending possible elevator group at the separated floors;

[0052] Step S6: Determine whether there is a possible elevator group whose horizontal distance is less than or equal to the distance threshold. If so, proceed to step S7; otherwise, end.

[0053] Step S7: taking the undetermined possible elevator group whose horizontal distance is less than or equal to the distance threshold as the specific elevator group;

[0054] Step S8: Controlling whether the specific elevator of the specific elevator group stops at the separated floor and / or controlling the stopping period of the specific elevator during stopping at the separated floor, so that the specific elevator in the specific elevator group meets the time separation condition and / or the position separation condition.

[0055] Based on the same inventive concept, the present invention also provides an elevator group management system, comprising:

[0056] A designating unit for designating a separate floor where there are waiting passengers who need to take different destination elevators and the waiting passengers who need to take different destination elevators need to be separated to prevent the waiting passengers from taking non-destination elevators;

[0057] An information acquisition unit, which acquires elevator operation information and elevator request signals from waiting passengers;

[0058] A storage unit stores conditions for establishing a specific elevator group and corresponding time thresholds and distance thresholds; wherein the conditions for establishing a specific elevator group include:

[0059] Condition 1, consisting of two parking elevators that are traveling toward the separated floor and are about to stop at the separated floor;

[0060] Condition 2: the time interval between the stop periods of the two stop elevators meeting condition 1 when they stop at the separated floors is less than the time threshold;

This achieves time separation and / or position separation for waiting passengers on the separated floor who need to board different destination elevators. The elevator group management method of the present invention effectively prevents passengers waiting at separated floors from entering the wrong destination elevator, thereby improving the passenger experience, increasing elevator operating efficiency, and reducing elevator energy consumption.

[0069] The following describes the embodiments of the present invention through specific embodiments in conjunction with the accompanying drawings. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. In the following description, specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be based on different viewpoints and applications. Those skilled in the art can make various similar generalizations and substitutions without departing from the spirit of the present invention.

[0070] Example 1

[0071] The elevator group management system of this embodiment is as follows: Figure 1 As shown, including:

[0072] A designating unit, for designating a separate floor where there are waiting passengers who need to take different destination elevators and the waiting passengers who need to take different destination elevators need to be separated to prevent the waiting passengers from taking non-destination elevators;

[0073] An information acquisition unit, used to acquire elevator operation information and elevator request signals from waiting passengers;

[0074] A storage unit is used to store the conditions for establishing a specific elevator group and its corresponding time threshold and distance threshold; wherein the conditions for establishing a specific elevator group include:

[0075] Condition 1, consisting of two parking elevators that are traveling toward the separated floor and are about to stop at the separated floor;

[0076] Condition 2: the time interval between the stop periods of the two stop elevators meeting condition 1 when they stop at the separated floors is less than the time threshold;

[0077] Condition 3: the distance between the parking positions of the two elevators that meet condition 1 on the separated floors is less than the distance threshold;

[0078] a calculation unit for calculating, based on the elevator operation information and the elevator boarding request signal, a time interval between stop periods of two stop elevators constituting a specific elevator group during their stops at the separated floors and a horizontal distance between the stop positions at the separated floors;

[0079] a judgment unit, configured to judge whether a specific elevator group exists based on the establishment condition in the storage unit and its corresponding time threshold and distance threshold, and the time interval and horizontal distance calculated by the calculation unit;

[0080] The adjusting unit controls, when the determining unit determines that the specific elevator group exists, at least one elevator in the specific elevator group to stop at the separated floor, so that the establishment condition of the specific elevator group is not satisfied.

[0081] The elevator group management method of this embodiment controls the stopping (docking behavior and docking action) of a stop elevator about to stop at a separated floor at the separated floor, so that the stop elevator satisfies at least one of a time separation condition and a position separation condition when stopping at the separated floor. This achieves time separation and / or position separation for waiting passengers on the separated floor who need to board different destination elevators, allowing waiting passengers on the separated floor to correctly board their corresponding destination elevators, thereby preventing waiting passengers on the separated floor from boarding non-destination elevators.

[0082] The separated floor refers to a floor where there are waiting passengers who need to take different elevators and need to be separated to prevent them from boarding elevators other than their destinations. The time separation condition refers to the time interval between any two elevators stopping at the separated floor being greater than a time threshold. The position separation condition refers to the distance between any two elevators stopping at the separated floor being greater than a distance threshold. The time threshold is greater than the maximum duration that the elevators stop at the separated floor, and the distance threshold is greater than the minimum distance between any two elevators.

[0083] It should be noted that controlling the stopping of a parking elevator at separated floors mainly controls the stopping behavior and stopping action of the parking elevator. Among them, controlling the stopping behavior of the parking elevator mainly controls whether the parking elevator stops at separated floors, controls the number of waiting floors the parking elevator needs to stop at before reaching the separated floors, and controls the waiting floors the parking elevator needs to stop at. Controlling the stopping action of the parking elevator mainly controls the moving speed of the parking elevator, and controls the door opening and closing actions of the parking elevator when it stops at separated floors.

[0084] The group management method determines whether a specific elevator group exists based on elevator operation information and a boarding request signal from the waiting passengers. If the determination result is that the specific elevator group exists, at least one specific elevator in the specific elevator group is controlled to stop at the separated floors so that the specific elevators in the specific elevator group meet the time separation condition and / or the position separation condition. The specific elevator group is composed of two stopping elevators that neither meet the time separation condition nor the position separation condition, and the specific elevators are the stopping elevators that constitute the specific elevator group.

[0085] Specifically, first, it is determined whether the elevator is the parking elevator based on the elevator operation information and the elevator request signal. If so, it is further determined whether the two parking elevators meet the time separation condition and the position separation condition. If not, the two parking elevators are determined as specific elevators, and the two parking elevators form a specific elevator group.

[0086] The elevator operation information includes the operation direction, the car position and the information of the floors to be stopped. The group management method determines whether the elevator is heading towards the separated floors based on the operation direction, the car position and the separated floors. When it is determined that the elevator is heading towards the separated floors and the floors to be stopped by the elevator include the separated floors, the group management method determines that the elevator is the stopping elevator.

[0087] Controlling the stopping of the specific elevator at the separate floor includes at least one of controlling whether the specific elevator stops at the separate floor and controlling a stopping period during which the specific elevator stops at the separate floor.

[0088] The elevator group management method of this embodiment is as follows: Figure 2 As shown, the following steps are included:

[0089] Step S1, obtaining the elevator operation information and the elevator request signal of the waiting passenger;

[0090] Step S2: enumerate all possible elevator groups consisting of any two elevators;

[0091] Step S3, calculating the time interval between the stop periods of the two elevators corresponding to each possible elevator group during their stop at the separated floors and the horizontal distance between the stop positions at the separated floors according to the elevator operation information and the elevator request signal;

[0092] Step S4: Determine whether the specific elevator group exists based on the time interval and the horizontal distance. If yes, proceed to step S5; otherwise, end.

[0093] Step S5: Controlling whether at least one of the specific elevators stops at the separated floor and / or controlling the stopping period of at least one of the specific elevators during stopping at the separated floor, so that the specific elevators in the specific elevator group meet the time separation condition and / or the position separation condition.

[0094] Based on the same inventive concept, the elevator group management method of this embodiment is also as follows Figure 3 As shown, the following steps are included:

[0095] Step S1, obtaining the elevator operation information and the elevator user's elevator request signal;

[0096] Step S2: enumerate all possible elevator groups consisting of any two elevators;

[0097] Step S3, calculating the time interval between the stop periods of two elevators corresponding to each possible elevator group during the stop period at the separated floors according to the elevator operation information and the elevator request signal;

[0098] Step S4: Select a possible elevator group whose time interval is less than the time threshold from all possible elevator groups as a pending possible elevator group;

[0099] Step S5: Calculate the horizontal distance of the pending possible elevator group using the parking positions of the elevators in the pending possible elevator group at the separated floors;

[0100] Step S6: Determine whether there is a possible elevator group whose horizontal distance is less than or equal to the distance threshold. If so, proceed to step S7; otherwise, end.

[0101] Step S7: taking the undetermined possible elevator group whose horizontal distance is less than or equal to the distance threshold as the specific elevator group;

[0102] Step S8: Controlling whether the specific elevator of the specific elevator group stops at the separated floor and / or controlling the stopping period of the specific elevator during stopping at the separated floor, so that the specific elevator in the specific elevator group meets the time separation condition and / or the position separation condition.

[0103] The system and method of this embodiment controls the stop elevator that is about to stop at the separated floor according to the elevator operation information and the elevator request information of the waiting passengers, so that the stop elevator satisfies at least one of the time separation condition and the position separation condition when stopping at the separated floor. In this way, it can be ensured that the horizontal distance between the stop elevators that stop at the separated floors is far enough within a time length less than a time threshold or that the time difference between the stop periods of the stop elevators that stop at the separated floors at the separated floors is large enough within a horizontal distance less than a distance threshold, thereby realizing time separation and / or position separation of the waiting passengers who need to take different target elevators on the separated floors, effectively avoiding the passengers waiting at the separated floors from entering the wrong target elevator, thereby improving the elevator riding experience of the waiting passengers, improving the elevator operation efficiency and thus reducing the elevator's power consumption.

[0104] Example 2

[0105] Based on the first embodiment, this embodiment defines how to control the parking of a specific elevator at the separated floor so that the specific elevator group is no longer formed.

[0106] The stopping of the specific elevator at the separated floor is controlled by controlling whether the specific elevator stops at the separated floor.

[0107] Specifically, the elevator request signal assigned to the first specific elevator in the specific elevator group and having the separated floor as the departure floor is changed so that the first specific elevator does not stop at the separated floor, thereby reducing the number of stopping elevators constituting the changed specific elevator group to one. In this way, the establishment condition of the specific elevator group is no longer met, and the specific elevator group is eliminated.

[0108] By distributing the boarding request signal originally assigned to the first specific elevator and having the separated floor as the departure floor to other elevators, the first specific elevator is prevented from stopping at the separated floor. There are two ways to achieve this:

[0109] In the first mode, when the following conditions are met, the group management method assigns all boarding request signals originally assigned to the first specific elevator and having the separated floor as the departure floor to the second specific elevator in the specific elevator group, so that the first specific elevator does not stop at the separated floor:

[0110] Condition 1: The first specific elevator and the second specific elevator have the same running direction;

[0111] Condition 2: The destination floor of the passengers in the car of the first specific elevator does not include the separated floor;

[0112] Condition 3: The remaining resources of the second specific elevator are greater than the required resources of the waiting passengers corresponding to the newly allocated elevator request signal. The remaining resources here can be the remaining number of people that can be accommodated in the car, the remaining weight that can be accommodated in the car, the remaining area in the car, etc.

[0113] For example, in a specific scenario, there are passengers waiting for different elevators in a building. Separation is required to prevent these passengers from boarding non-destination elevators. The separation floor is the 5th floor. There are five passengers waiting for the elevator on the 5th floor. Elevator #1 is descending from the 7th floor, and there are no passengers in the car who are getting off on the 5th floor. The group management system has assigned the three passengers who are waiting for the elevator to descend from the 5th floor to elevator #1. Elevator #2 is descending from the 9th floor, and there is room for five more passengers in the car. The group management system has assigned the remaining two passengers who are also going to descend from the 5th floor to elevator #2. If elevators #1 and #2 no longer meet the time separation and distance separation conditions on the 5th floor, the group management system will reassign the three passengers originally assigned to elevator #1 to elevator #2. This eliminates the need for elevator #1 to stop at the separation floor, the 5th floor, and elevators #1 and #2 no longer constitute a specific elevator group.

[0114] In a second manner, when the following conditions are met, the group management method distributes all boarding request signals originally assigned to the first specific elevator and having the separation floor as the departure floor to other elevators outside the specific elevator group where the first specific elevator is located, so that the first specific elevator does not stop at the separation floor:

[0115] Condition A: There is at least one other elevator that runs in the same direction as the first specific elevator and whose remaining resources are not less than the required resources of all waiting passengers corresponding to the newly allocated elevator request signals;

[0116] Condition B: the destination floor of the passengers in the car of the first specific elevator does not include the separated floor;

[0117] Condition C: the other elevators meet the position separation condition and / or the time separation condition after receiving the newly added elevator request signal.

[0118] For example, in a specific scenario, there are passengers waiting for different destinations in a building. Separation is required to prevent these passengers from boarding non-destination elevators. The separation floor is the 5th floor. Elevator 1 is descending from the 10th floor, and there are no passengers waiting for the 5th floor in its car. The group management system has assigned three passengers who wish to descend from the 5th floor to elevator 1. Elevator 2 is ascending from the 1st floor, and the group management system has assigned two passengers who wish to ascend from the 5th floor to elevator 2. Elevators 1 and 2 do not meet the time and distance separation conditions on the separation floor, the 5th floor, and therefore form a specific elevator group. At this time, elevator 3 is descending from the 12th floor, and there is still room for five passengers. The group management system reassigns the three passengers originally assigned to elevator 1 to elevator 3 (before and after elevator 3 receives these three new passengers, it does not form a specific elevator group with other elevators). This eliminates the need for elevator 1 to stop at the separation floor, the 5th floor, and elevators 1 and 2 no longer form a specific elevator group.

[0119] Example 3

[0120] Different from the second embodiment, this embodiment controls the parking of a specific elevator at the separated floors in a different manner.

[0121] Controlling the stop of the specific elevator at the separated floor is achieved by controlling the stop period during which the specific elevator stops at the separated floor, specifically, controlling at least one of the start time, stop duration, and end time of the stop period.

[0122] The elevator operation information includes information about the operating direction, car position, and floor to be stopped. The group management method estimates the start time of the specific elevator's stop at the intervening floor based on the operating direction, car position, and the floor to be stopped before the specific elevator arrives at the intervening floor. Specifically, the method first estimates the first start time of the specific elevator's stop at the intervening floor based on the car position and operating direction of the specific elevator. Then, based on the floor to be stopped before the specific elevator arrives at the intervening floor, the method estimates the total stop time of the specific elevator at the floor to be stopped, the deceleration time difference corresponding to the deceleration process of the specific elevator to the floor to be stopped relative to the uniform speed time of the specific elevator traveling at the rated speed over the corresponding travel distance during the deceleration process, and the acceleration time difference corresponding to the acceleration process of the specific elevator starting from the floor to be stopped relative to the uniform speed time of the specific elevator traveling at the rated speed over the corresponding travel distance during the acceleration process. Finally, the method uses the total stop time, deceleration time difference, and acceleration time difference to adjust the first start time of each specific elevator to obtain a final start time.

[0123] The following describes a specific method for controlling the stopping period of the specific elevator during the stopping period of the separated floors.

[0124] The first method is to control the start time of the stop period of at least one of the two specific elevators in the specific elevator group during its stop at the separated floor so that the stop period satisfies the time separation condition. Specifically, the start time of the stop period of the specific elevator during its stop at the separated floor is changed by controlling an action executed before the specific elevator arrives at the separated floor. Specifically, the following three situations are included:

[0125] Solution 1: changing the moving speed of the first specific elevator in the specific elevator group traveling to the separated floor;

[0126] Solution 2: changing the number of floors to be stopped between the current position of the specific elevator and the separated floors;

[0127] Solution 3, changing the stop duration of the specific elevator during the stop at the to-be-stopped floor between the current position and the separated floor;

[0128] Through the above three solutions, the moving time required for the first specific elevator to move from its current position to the separated floor can be changed, thereby changing the starting time of the stop period during which the first specific elevator stops at the separated floor.

[0129] In the above-mentioned scheme 2, the number of floors to be stopped between the current position and the separated floor corresponding to the first specific elevator can be changed by changing the elevator request signal assigned to the first specific elevator with the floor between the current position and the separated floor as the departure floor, mainly by changing the correspondence between the first specific elevator and the elevator request signal with the floor between the separated floor and the current position of the first specific elevator as the departure floor.

[0130] When the following conditions are met, the group management method reallocates the boarding request signal originally assigned to the first specific elevator, which has an intermediate floor between the partition floor and the current position of the first specific elevator, to another substitute elevator other than the specific elevator group where the first specific elevator is located:

[0131] Condition a: The first specific elevator is assigned the boarding request signal with the intermediate floor between the partition floor and the current position of the first specific elevator as the departure floor, and the destination floor of the first specific elevator does not include the intermediate floor;

[0132] Condition b: After the boarding request signal with the middle floor between the separated floor and the current position of the first specific elevator as the departure floor is reallocated, the time interval between the stopping periods of two specific elevators in the specific elevator group to which the first specific elevator originally corresponds, during which the two specific elevators stop at the separated floor, is greater than the time threshold;

[0133] Condition c: There exists at least one alternative elevator that is capable of responding to the reallocated elevator request signal and that travels in the same direction as the first specific elevator. Here, "the alternative elevator is capable of responding to the reallocated elevator request signal" means that the remaining resources of the alternative elevator are not less than the required resources of the waiting passengers corresponding to all newly allocated elevator request signals.

[0134] Condition d: If the destination floor of the replacement elevator or the destination floor of the reallocated elevator request signal includes the separated floor, the replacement elevator and any other elevator shall satisfy the time separation condition and / or the position separation condition at the separated floor.

[0135] When the following conditions are met, the group management method reallocates the boarding request signal originally assigned to elevators other than the specific elevator group, with the floor between the intermediate floor and the current position of the first specific elevator in the specific elevator group as the departure floor, to the first specific elevator, thereby changing the waiting floor for the specific elevator between its current position and the intermediate floor:

[0136] Condition 1: There is at least one elevator other than the specific elevator group and running in the same direction as the first specific elevator, and the elevator request signal is assigned to a floor between the intervening floor and the current position of the first specific elevator as the departure floor;

[0137] Condition 2: After the boarding request signal with the floor between the separating floor and the current position of the first specific elevator as the departure floor is reallocated to the first specific elevator of the specific elevator group, the time interval between the stopping periods of the two specific elevators constituting the specific elevator group while stopping at the separating floor is greater than the time threshold;

[0138] Condition 3: After all the elevator request signals with the floors between the partition floor and the current position of the first specific elevator as departure floors are reallocated, the other elevator will not form a specific elevator group with the remaining elevators.

[0139] In the above solution 2, the intermediate waiting floor of at least one specific elevator in the specific elevator group can be changed by transferring the elevator request signal with the floor between the partition floor and the current position of the first specific elevator as the departure floor from one specific elevator in the specific elevator group to another specific elevator. Specifically, there are two cases:

[0140] Case 1: All the elevator request signals originally assigned to the first specific elevator of the specific elevator group and corresponding to at least one departure floor are transferred to the second specific elevator of the specific elevator group, thereby changing the waiting floors of the first specific elevator. When the waiting floors of the second specific elevator do not include the departure floor of the reallocated elevator request signal, the waiting floors of the second specific elevator are also changed at the same time.

[0141] In case 2, when at least one of the waiting-for-stop floors of a first specific elevator constituting the specific elevator group does not belong to the waiting-for-stop floors of a second specific elevator constituting the specific elevator group, some or all of the boarding request signals corresponding to the waiting-for-stop floors belonging to the first specific elevator but not belonging to the waiting-for-stop floors of the second specific elevator are transferred from the first specific elevator to the second specific elevator, thereby changing the waiting-for-stop floors of the second specific elevator. Furthermore, when all of the boarding request signals corresponding to a waiting-for-stop floor belonging to the first specific elevator but not belonging to the waiting-for-stop floors of the second specific elevator are transferred to the second specific elevator, the waiting-for-stop floor of the first specific elevator is simultaneously changed.

[0142] The second method is to change the dwelling duration and / or end time of the dwelling period of the specific elevator that has arrived at the intervening floor by controlling the actions performed by the specific elevator that has arrived at the intervening floor during the dwelling period at the intervening floor. Here, the dwelling duration and / or end time can be controlled by controlling the car door opening speed, car door closing speed, and the duration for which the car door remains open when the specific elevator that has arrived at the intervening floor stops at the intervening floor.

[0143] The present invention has been described in detail above through specific embodiments. The above embodiments are merely preferred embodiments of the present invention and the present invention is not limited to the above embodiments. Without departing from the principles of the present invention, equivalent substitutions and improvements made by those skilled in the art should be considered within the technical scope protected by the present invention.
