Description

Elevator system and its control method

[0001] The present invention relates to an elevator system and a control method thereof.

[0002] An elevator includes an elevator car that moves along a vertical shaft formed inside a building, a traction machine that generates power to raise and lower the elevator car, and a power transmission member that transmits the power of the traction machine to the car.

[0003] An elevator car moves along a vertical shaft formed within a building. Motors, traction machines, and other devices are installed to generate power to raise and lower the elevator car. One or more elevators installed within a building can be controlled and managed in an integrated manner.

[0004] Elevators allow for the vertical movement of people, cargo, animals, plants, and / or robots within a building. Recently, robot-based services have become increasingly popular. Various interoperable control technologies between robots and elevators are being developed to enable robots to ride elevators and move between floors within a building.

[0005] Prior art document, Patent Publication No. 10-1998-0009076, discloses a group management control technology that controls multiple elevators installed in a building to operate organically based on a predetermined allocation rule. According to this, for a hall call that has occurred, a comprehensive evaluation value for allocation is obtained using the status information and prediction information of each elevator, and a position evaluation value is obtained using the hall button and the elevator allocation priority table, and then the two evaluation values ​​are combined to select the optimal allocation unit, or the comprehensive evaluation value is obtained using the status information and prediction information of the elevator, the button position of the hall call, and the elevator position evaluation value, and the optimal unit is allocated.

[0031]

[0032] Figure 1 schematically illustrates a robot (310) and a non-robot (320), such as a person, riding in an elevator car (EC) included in the elevator system of the present invention.

[0033] Referring to FIG. 1, the elevator car (EC) included in the elevator system of the present invention can accommodate not only non-robots (320) such as people, cargo, animals / plants, etc., but also robots (310). In the present specification, the robot (310) is used as a concept broadly encompassing autonomous vehicles, unmanned vehicles, and other mechanical devices that automatically move and / or perform tasks or are controlled externally. The robot (310) may be a service robot for providing services on at least one floor within a building.

[0034] According to the elevator system and control method of the present invention, when a new call is made by a passenger, if the elevator car door remains open for a certain period of time longer than usual, an allocation suppression weight is applied to the corresponding car or the corresponding car is excluded from allocation. This will be discussed in detail below.

[0035]

[0036] Figure 2 is a schematic flowchart of an elevator system control method according to one embodiment of the present invention.

[0037] Referring to FIG. 2, the elevator system control method of the present embodiment includes a new call generation step (S110), a step of calculating an allocation temporary evaluation value (X) of a target unit for operation for a new call (S120), a step of determining whether it is a peak time (S130), a step of determining whether an elevator car is stopped at a boarding floor (S140), a step of determining whether the scheduled operation direction of the elevator car is the same as the direction of the new call (S150), a step of determining whether the door of the elevator car is open (S160), a step of determining whether a hold call is registered on another floor (S170), a step of determining whether there is a passenger in the elevator car (S180), a step of calculating and adding (T) the elapsed time since the door was opened and the expected arrival time of a passenger who has already been called (S190), a step of determining whether a previously registered call having the same departure floor and destination floor as the new call exists in the target unit for operation (S200), a step of selecting a first threshold (A) (S210), and a step of selecting a second threshold (B). It may include at least one of the following steps: a step (S220), a step (S230) of determining whether the sum (T) of the elapsed time of the door opening and the expected arrival time of the pre-registered call passenger is greater than the first threshold (A), a step (S240) of determining whether the sum (T) of the elapsed time of the door opening and the expected arrival time of the pre-registered call passenger is greater than the second threshold (B), a step (S250) of calculating the final allocation evaluation value (Y) by imposing a suppression weight on the temporary allocation evaluation value (X) of the operation target unit for a new call, a step (S260) of excluding the operation target unit for a new call from the allocation candidate unit, a step (S270) of determining the temporary allocation evaluation value (X) of the operation target unit for a new call as the final allocation evaluation value (Y), a step (S280) of selecting the unit with the smallest final allocation evaluation value (Y) from the allocation candidate unit as the optimal unit, and a step (S290) of assigning the new call to the optimal unit.

[0038]

[0039] (1) New call generation step (S110)

[0040] A new call is generated by the new caller entering the desired destination. In this specification, the new caller, including a robot (310) and a non-robot (320), is referred to as a "passenger."

[0041] A new call can be generated by a passenger entering the destination floor on a call device installed at the boarding gate, or by remotely entering the destination floor using an application installed on a smartphone. Furthermore, if the robot (310) is the passenger, the call can be generated by the robot (310) or the robot management system transmitting a destination floor input signal.

[0042] If a passenger inputs the destination floor on the call device installed at the elevator, the floor on which the call device is installed, i.e. the floor on which the new call originates, can be the 'boarding floor' on which the passenger wishes to board the elevator.

[0043] If a passenger enters the destination floor remotely, the floor where the passenger is located can be set as the boarding floor (if the passenger's location can be confirmed through smartphone location tracking, etc.), or the passenger can directly enter the boarding floor.

[0044] If the passenger is a robot (310), the floor where the robot (310) is located can be set as the boarding floor, and the robot (310) or the robot management system can transmit boarding floor information.

[0045] When a new call occurs (S110), the temporary evaluation value (X) of the target machine for the new call can be calculated (S120).

[0046]

[0047] (2) Step for calculating the temporary evaluation value (X) assigned to the target machine for the new call (S120)

[0048] When a new call occurs, the allocation temporary evaluation value (X) of the target call is calculated. The allocation temporary evaluation value (X) is a value calculated in the previous step to determine the allocation final evaluation value (Y), and the call with the smallest allocation final evaluation value (Y) is selected as the optimal call.

[0049] The allocation temporary evaluation value (X) is calculated using values ​​such as the expected arrival time of the target unit in the floor direction of a new call, the expected arrival time of the target unit in the floor direction of an already registered call, etc., and the lower the allocation temporary evaluation value (X), the more suitable the elevator unit is evaluated for allocation. The 'target units for calculation' can be all elevator units installed in the building, and the allocation temporary evaluation value (X) can be calculated for each elevator unit.

[0050] In this specification, an elevator car refers to an ID assigned to each elevator shaft. Typically, one elevator car (EC) is placed in one elevator car. However, the present invention is not limited to this, and multiple elevator cars (EC) may be placed in one elevator car.

[0051]

[0052] (3) Step for determining whether it is peak time (S130)

[0053] To improve traffic flow during peak hours when traffic flow is not smooth, it is possible to determine whether the time a new call occurs is during peak hours.

[0054] Peak hours can be determined by whether the current traffic volume exceeds a threshold. Machine learning can be used to recognize current traffic volume and determine the threshold.

[0055] If the time when a new call occurs is during a peak time period ('Yes' in S130), it can be determined whether the elevator car (EC) is stopped at the boarding floor. If the time when a new call occurs is not during a peak time period ('No' in S130), the temporary evaluation value (X) of the target unit for the new call can be determined as the final evaluation value (Y) of the assignment (S270).

[0056]

[0057] (4) Step for determining whether the elevator car is stopped at the boarding floor (S140)

[0058] If the elevator car (EC) is not stopped at the boarding floor, a passenger cannot board the elevator car (EC) at the boarding floor or the door of the elevator car (EC) cannot be open at the boarding floor, so it is determined whether the elevator car (EC) is stopped at the boarding floor where the passenger wants to board the elevator.

[0059] If the elevator car (EC) is stopped at the boarding floor ('Yes' in S140), it can be determined whether the scheduled direction of operation of the elevator car (EC) is the same as the direction of the new call (S150). If the elevator car (EC) is not stopped at the boarding floor ('No' in S140), the temporary evaluation value (X) of the target unit for the operation for the new call can be determined as the final evaluation value (Y) of the assignment (S270).

[0060]

[0061] (5) Step for determining whether the elevator car's planned operating direction is the same as the direction of the new call (S150)

[0062] If the scheduled direction of an elevator car (EC) stopped at the boarding floor is different from the direction of a new call, the elevator car (EC) will not move to the floor desired by the new call passenger. Therefore, it is determined whether the scheduled direction of an elevator car (EC) stopped at the boarding floor is the same as the direction of the new call. For example, if the boarding floor of a new call is the 3rd floor and the destination floor of the new call is the 10th floor, it is determined whether the elevator car (EC) stopped at the boarding floor, the 3rd floor, is scheduled to move upward.

[0063] If the scheduled operation direction of the elevator car (EC) is the same as the direction of the new call ('Yes' in S150), it can be determined whether the door of the elevator car (EC) is open (S160). If the scheduled operation direction of the elevator car (EC) is not the same as the direction of the new call ('No' in S150), the temporary evaluation value (X) of the target unit for the operation for the new call can be determined as the final evaluation value (Y) of the allocation (S270).

[0064]

[0065] (6) Step for determining whether the elevator car door is open (S160)

[0066] In order to measure the elapsed time since the door of an elevator car is opened (which may include being closed), it is determined whether the door of an elevator car (EC) stopped on a boarding floor is open (which may include being closed). If the door of the corresponding elevator car (EC) is open ('Yes' in S160), it can be determined whether a hold call is registered on another floor (S170). If the door of the corresponding elevator car (EC) is closed ('No' in S160), the temporary evaluation value (X) of the target unit for the operation for the new call can be determined as the final evaluation value (Y) of the allocation (S270).

[0067]

[0068] (7) Step for determining whether a call is registered on another floor (S170)

[0069] Determine whether a hall call has been registered on a floor other than the boarding floor. If no hall call has been registered on a floor other than the boarding floor and there are no passengers in the elevator car (EC), there is no need to consider factors such as the elapsed time since the door opened, as no other passengers would experience inconvenience even if the door opened for a long time.

[0070] A hall call refers to a passenger outside the elevator car (EC) calling the elevator to the floor, and a car call refers to a passenger inside the elevator car (EC) entering the destination floor.

[0071] However, by entering the destination floor in advance using a call device installed on the platform or a smartphone, etc., a hold call is registered from outside the elevator car (EC), and when the car performs the hold call service in a state matching the call direction (i.e., when the car arrives at the floor where the passenger is waiting in a state matching the call direction), the group management system automatically registers the passenger's destination floor on the car side without requiring any additional action from the passenger boarding the car, thereby causing the car to drive to the destination floor.

[0072] If a hold call has not been registered on another floor (S170: "No"), it can be determined whether there are passengers in the elevator car (EC) (S180). If a hold call has been registered on another floor (S170: "Yes"), the elapsed time since the door opened and the expected arrival times of the registered call passengers can be calculated and added together (T) (S190).

[0073]

[0074] (8) Step for determining whether there are passengers in the elevator car (S180)

[0075] Determine whether there are passengers in the elevator car (EC) stopped at the boarding floor. If no hall call is registered on a floor other than the boarding floor and there are no passengers in the EC, there is no need to consider factors such as the elapsed time since the door opened, as no other passengers would experience inconvenience even if the door opened for a long time.

[0076] To determine whether there are passengers in the elevator car (EC), a video device or weight sensor installed in the elevator car (EC) can be used.

[0077] If there are passengers boarding the elevator car (EC) stopped at the boarding floor ('Yes' in S180), the elapsed time since the door opened and the expected arrival times of the passengers already called can be calculated and added together (T) (S190). If there are no passengers boarding the elevator car (EC) stopped at the boarding floor ('No' in S180), the provisional evaluation value (X) of the target unit for the operation for the new call can be determined as the final evaluation value (Y) of the assignment (S270).

[0078]

[0079] (9) Step (S190) of calculating and adding up the elapsed time of door opening and the expected arrival time of the registered call passenger.

[0080] In order to compare the sum (T) of the door opening time and the expected arrival time of the pre-registered call passenger with the thresholds (A, B), the door opening time of the elevator car (EC) stopped at the boarding floor and the expected arrival time of the pre-registered call passenger are each calculated and summed (T).

[0081] If new calls continue to be registered for the elevator car (EC) even when the door opening time of the elevator car (EC) is long, the delay time of the elevator car (EC) may be long.

[0082] Additionally, if a new call is registered while the passenger is far away from the elevator car, it may take a long time for the passenger to arrive at the elevator car (EC) on the boarding floor.

[0083] Even in such cases, if passengers already in the elevator car (EC) are forced to wait, this will increase inconvenience and dissatisfaction not only for passengers in the elevator car (BC), but also for passengers waiting on other floors. Furthermore, prolonged wait times for the elevator car (EC) can negatively impact overall traffic flow.

[0084] Therefore, the door opening time of the elevator car (EC) stopped at the boarding floor and the expected arrival time of the registered call passenger are added together, and the value is used as a factor influencing the selection of the optimal car.

[0085] To calculate the expected arrival time of a pre-registered call passenger, the expected arrival time can be derived using data from existing passengers.

[0086] Figure 3 schematically illustrates the distance between a passenger and an elevator car on the boarding floor. Referring to Figure 3, the expected arrival time of a passenger can be calculated based on the distance (d) between the passenger (310, 320) and the elevator car (340) on the boarding floor. To calculate the expected arrival time of a passenger, communication with a smart terminal, images captured by a video device (330), etc. can be utilized.

[0087] Figure 4 schematically illustrates the distance between a security gate and an elevator car on the boarding floor. Referring to Figure 4, the expected arrival time of the passenger can be calculated based on the distance (d') between the security gate (350) that recognizes the passenger's security information (employee ID, smart device, etc.) and the elevator car (340) on the boarding floor. If the passenger is a robot (310), the robot can obtain permission through communication with the security system linked to the security gate (350) and pass through the security gate (350). To calculate the expected arrival time of the passenger, the image recognized by the video device (330) can be utilized.

[0088] If the arrival time of the passenger can be predicted in real time (if location tracking is possible by a smartphone, if the passenger is a robot (310), etc.), the real-time expected arrival time of the passenger can be used.

[0089]

[0090] (10) Step (S200) for determining whether a 'new call' and a 'pre-registered call with the same departure floor and destination floor' exist in the target machine for operation, step (S210) for selecting a first threshold (A), and step (S220) for selecting a second threshold (B).

[0091] In order to select the first threshold (A) or the second threshold (B) depending on whether there is a pre-registered call, in the calculation target unit (S120) where the assigned temporary evaluation value (X) for the new call was calculated, it is determined whether there is a 'new call' and a 'pre-registered call with the same departure floor and destination floor'.

[0092] If a 'new call' and a 'pre-registered call with the same departure and destination floors' do not exist in the target unit of the operation ('No' in S200), the first threshold (A) can be selected (S210). If a 'new call' and a 'pre-registered call with the same departure and destination floors' exist in the target unit of the operation ('Yes' in S200), the second threshold (B), which is a value greater than the first threshold (A), can be selected (S220).

[0093] When a "new call" and a "pre-registered call with the same departure and destination floor" exist, assigning the new call to the elevator car (EC) may be more efficient in terms of overall traffic flow than excluding the new call from the elevator car, even if it means a longer wait time for passengers already in the EC. Therefore, in this case, a second threshold (B), which is larger than the first threshold (A), can be selected to further expand the registration range of the new call.

[0094]

[0095] (11) Step (S230) for determining whether the sum of the elapsed time of door opening and the expected arrival time of the registered call passenger (T) is greater than the first threshold (A).

[0096] If the first threshold (A) is selected (S210), it can be determined whether the sum (T) of the elapsed time since the door was opened and the expected arrival time of the registered call passenger is greater than the first threshold (A) (S220). If the sum (T) of the elapsed time since the door was opened and the expected arrival time of the registered call passenger is greater than the first threshold (A), the delay time of the corresponding elevator unit is determined to be excessively long, and new call assignments to the corresponding elevator unit can be restricted or excluded.

[0097] If the sum (T) of the elapsed time of door opening and the expected arrival time of the pre-registered call passenger is greater than the first threshold (A) ('Yes' in S230), a suppression weight is applied to the temporary allocation evaluation value (X) of the target unit for the new call to calculate the final allocation evaluation value (Y) (S250), or the target unit for the new call can be excluded from the group of units for allocation candidates (S260). If the sum (T) of the elapsed time of door opening and the expected arrival time of the pre-registered call passenger is less than or equal to the first threshold (A) ('No' in S230), the temporary allocation evaluation value (X) of the target unit for the new call can be determined as the final allocation evaluation value (Y) (S270).

[0098]

[0099] (12) Step (S240) for determining whether the sum of the elapsed time of door opening and the expected arrival time of the registered call passenger (T) is greater than the second threshold (B).

[0100] If the second threshold (B) is selected (S220), it can be determined whether the sum (T) of the elapsed time since the door was opened and the expected arrival time of the registered call passenger is greater than the second threshold (B) (S240). If the sum (T) of the elapsed time since the door was opened and the expected arrival time of the registered call passenger is greater than the second threshold (B), the delay time of the corresponding elevator unit is determined to be excessively long, and new call assignments to the corresponding elevator unit can be restricted or excluded.

[0101] If the sum (T) of the elapsed time of door opening and the expected arrival time of the pre-registered call passenger is greater than the second threshold (B) ('Yes' in S240), a suppression weight is applied to the temporary allocation evaluation value (X) of the target unit for the new call to calculate the final allocation evaluation value (Y) (S250), or the target unit for the new call can be excluded from the group of units for allocation candidates (S260). If the sum (T) of the elapsed time of door opening and the expected arrival time of the pre-registered call passenger is less than or equal to the second threshold (B) ('No' in S240), the temporary allocation evaluation value (X) of the target unit for the new call can be determined as the final allocation evaluation value (Y) (S270).

[0102]

[0103] (13) A step for calculating a final allocation evaluation value (Y) by applying a suppression weight to the allocation temporary evaluation value (X) of the operation target unit for a new call (S250), and a step for excluding the operation target unit for a new call from the allocation candidate unit (S260).

[0104] If the sum of the elapsed time of door opening and the expected arrival time of the passenger who has already registered a call (T) is greater than the first threshold (A) or the second threshold (B) ('Yes' in S230 or S240), a suppression weight is applied to the temporary evaluation value (X) of the target unit for the new call to calculate the final evaluation value (Y) of the allocation (S250), or the target unit for the new call can be excluded from the group of candidates for allocation (S260).

[0105] If the sum of the elapsed time since the door opened and the expected arrival time of the registered call passenger (T) is greater than the threshold (A or B), it means that the waiting time of the passengers already on board the elevator car (EC) or the passengers waiting on other floors will be longer. In this case, the elevator car (EC) should be assigned fewer new calls or no new calls should be assigned.

[0106] In the case where a suppression weight is applied to the allocation temporary evaluation value (X) of an elevator to be operated for a new call to calculate the final allocation evaluation value (Y) (S250), a suppression weight is applied to an elevator unit in which the sum of the elapsed time since the door was opened and the expected arrival time of a passenger who has already registered a call (T) is greater than the first threshold (A) or the second threshold (B), thereby increasing the final allocation evaluation value (Y). Since the elevator unit in question is not excluded from allocation, if the final allocation evaluation value (Y) of another elevator unit is higher due to other factors, there is a possibility that the elevator unit in question will be selected as the optimal unit.

[0107] In the case where the elevator target for a new call is excluded from the candidate elevators for allocation, the elevators for which the sum of the elapsed time since the door was opened and the expected arrival time of the registered call passenger (T) is greater than the first threshold (A) or the second threshold (B) are excluded from the candidate elevators for allocation, and therefore, the elevators are not selected as the optimal elevators.

[0108] Whether to calculate the final allocation evaluation value (Y) by applying a suppression weight to the allocation temporary evaluation value (X) of the operation target unit for a new call (S250) or to exclude the operation target unit for a new call from the allocation candidate unit (S260) can be selected by the customer or the elevator management system depending on the situation.

[0109]

[0110] (14) Step (S270) for determining the allocation temporary evaluation value (X) of the operation target for a new call as the allocation final evaluation value (Y)

[0111] The temporary evaluation value (X) of the allocation target for the new call, which was calculated in the previous step (S120), is determined as the final evaluation value (Y) of the allocation that serves as the criterion for selecting the optimal call.

[0112]

[0113] (15) A step of selecting the unit with the smallest final allocation evaluation value (Y) from the allocation candidate units as the optimal unit (S280), and a step of assigning a new call to the optimal unit (S290).

[0114] Among the allocation candidate units, the unit with the smallest final allocation evaluation value (Y) is selected as the optimal unit (S280), and a new call is assigned to the selected optimal unit (S290).

[0115]

[0116] According to the present invention, when information about a passenger who has registered a new call can be confirmed, the threshold values ​​(S210, S220) can be applied differently depending on the passenger type. For example, if the passenger is a robot (310), if a new call is automatically generated when the passenger touches their employee ID card to a gate, etc., if the passenger registers a new call after verifying their identity on a call device, or if the passenger provides their information to a smartphone application, the information about the passenger who has registered a new call can be confirmed. In addition, the information about the passenger who has registered a new call can be confirmed through a video device. By utilizing the video device, wheelchairs, strollers, etc. can be recognized, and corresponding customized passenger services can be provided.

[0117] For example, passenger types can be divided into robots (310), priority passengers, and general passengers. Since robots (310) may have different movement speeds and boarding conditions than non-robots (320), such as humans, a threshold value appropriate for the robot (310) can be set separately. For robots (310), the threshold value can be set higher than that for general passengers. For example, priority passengers may be passengers with relatively slow movement speeds, such as the disabled or elderly, or passengers to whom convenience is desired, such as VIPs or employees. For priority passengers, the threshold value can be set higher than that for general passengers. General passengers may include passengers other than robots (310) and priority passengers.

[0118] The threshold value can be adjusted manually or automatically based on preset conditions.

[0119] According to the present invention, in a system operating multiple elevators, the concentration of new calls in a specific elevator can be alleviated. This can shorten passenger waiting times, improve traffic flow in a system operating multiple elevators, and contribute to energy savings by improving elevator operation efficiency.

[0120]

[0121] It is obvious to those skilled in the art that the present invention is not limited to the above embodiments, and that various modifications or variations can be made without departing from the technical spirit of the present invention.
