FIG. 4 is a flowchart for explaining an example of a response basket change determination process in the group management control device according to the first embodiment.

  As shown in FIG. 1, a group management control device 1 as an elevator group management control device of the present embodiment performs group management of an elevator group 2 and performs an efficient operation service. Here, the elevator group 2 includes a plurality of elevators 3 from No. A to No. D, and each of the plurality of cages 4 performs an operation service by moving up and down the hoistway. In the following description, the elevator group 2 is described as including four elevators 3 from No. A to No. D. However, the present invention is not limited to this, and the elevator group 2 may include two or three. Five or more may be provided. Further, in the following description, the four elevators 3 from No. A to No. D will be simply described as elevators 3 unless otherwise specified.

  Each elevator 3 includes a basket 4, a hall call button (a hall call operation unit) 5, a hall display unit 6, a single control device 7, and the like. The elevator 3 is capable of moving to any desired floor by controlling the driving of each part by the single controller 7 and moving the cage 4 up and down in the hoistway.

  The cage 4 is connected to a main rope, and is disposed in a hoistway provided along the vertical direction of the building, and can move up and down the hoistway. The cage 4 is connected to a counter weight via a main rope wound around a sheave of a hoisting machine provided corresponding to the car 4, and with the rotation of the sheave driven by the hoisting machine, the counter weight At the same time, they move up and down in opposite directions. The basket 4 includes a basket call button (basket call operation unit) for performing so-called basket call registration in accordance with an operation input by a user, a load detector for detecting a load in the basket 4, and the like.

  For example, the hall call buttons 5 are provided beside doors 9 (see FIG. 2) of the halls 8 (see FIG. 2) of the elevator stop floors where the car 4 can be landed. In response, so-called hall call registration is performed. The hall display unit 6 is for displaying the car 4 responding to the hall call registration from the hall 8 on the hall 8. For example, the upper and lower forecast lights (below the door 9 of each hall 8) Hall lantern) 10 (see FIG. 2).

  The single control device 7 includes a CPU (Central Processing Unit) connected to each other by a normal type bidirectional common bus, a ROM (Read Only Memory) pre-stored with a predetermined control program, etc. A RAM (Random Access Memory) for temporarily storing results, a backup RAM for storing information such as map data prepared in advance, the specifications of the elevator 3, and a microcomputer having an input / output port device and a drive circuit are provided. The unit control device 7 is electrically connected to various parts of the elevator 3 such as various sensors, detectors and hoisting machines, a car call button of the car 4, a load detector, a hall call button 5, and a hall display unit 6. The operation of each part of the elevator 3 is controlled centrally. For example, the single control device 7 controls the driving of the hoist according to the operation input from the user to the car call button and the hall call button 5, and sets the car 4 to the designated destination floor corresponding to the call registration. Move.

  Each elevator 3 configured as described above has a car call button and a hall call button 5 when a call operation of the car 4 is performed by a user via the car call button and the hall call button 5 of the car 4. Accordingly, a car call registration signal and a hall call registration signal corresponding to this are input to the single control apparatus 7, and the single control apparatus 7 performs a car call registration and a hall call registration of the car 4 according to the call registration signal. The single control device 7 is a group management control device to be described later based on the car call registration signal, the hall call registration signal, outputs from various sensors and detectors, the current moving direction (lifting direction) of the car 4, and the like. According to the allocation from 1, the hoisting machine is driven and controlled, and the basket 4 is moved to the target floor. Thereby, in each elevator 3, the cage 4 moves up and down in the vertical direction in the hoistway and moves to the landing 8 on an arbitrary destination floor. In each elevator 3, when it is detected that the cage 4 has landed on the landing 8 on the destination floor and has landed at a predetermined landing position, the single control device 7 then opens the door 9. As a result, a user waiting at the landing 8 can get into the car 4, and a user inside the car 4 can get off at the landing 8.

  The group management control device 1 includes a CPU (central processing unit), a ROM (Read Only Memory) preliminarily storing a predetermined control program, and the like, interconnected by a bidirectional common bus of a normal format, A RAM (Random Access Memory) that temporarily stores CPU calculation results, a backup RAM that stores information such as map data prepared in advance, the specifications of the elevator 3, and a microcomputer having an input / output port device and a drive circuit are provided. . The group management control device 1 communicates and exchanges information such as detection signals, drive signals, and control commands with each single control device 7 of the plurality of elevators 3 to manage the elevator group 2 as a group.

  For example, the group management control device 1 assigns an optimal car 4 that responds to the hall call registration from the hall 8 of the elevator 3 according to the state of each car 4 from the plurality of cars 4 of each elevator 3 and responds thereto. Group management control for displaying the basket 4 on the hall 8 is executed.

  The group management control device 1 is, for example, a car call registration signal, a hall call registration signal, outputs from various sensors and detectors, a current position and a moving direction (up and down direction) of the car 4, and a hall call predicted to be generated in the future. Based on the state of each elevator 3 and each cage 4 such as a car call and a predicted destination floor, a predetermined evaluation operation is performed on the generated call. Then, the group management control device 1 determines the landing order of the baskets 4 and the like so that each cage 4 responds optimally to each call while rationally moving according to the predetermined evaluation calculation. An elevator group 2 is assigned by assigning a cage 4 that responds to a call (hereinafter, also referred to as “response cage 4”), performing an assignment process for determining the answer cage 4, and efficiently allocating operations of the plurality of cages 4. As a whole, efficient operation services are provided. When the group management control device 1 assigns the cage 4 that responds to the hall call registration from the hall 8, the forecast light 10 provided in the hall 8 corresponding to the response cage 4 is immediately turned on, and which unit is Whether to respond to the hall call is displayed on the hall 8 and notified.

  The group management control device 1 according to the present embodiment executes the response basket change control under predetermined conditions when the hall call registration from the hall 8 is performed, so that the car 4 responds appropriately by the hall 8. Can be displayed.

  That is, when the hall call registration from the hall 8 is performed, the group management control device 1 of the present embodiment is on the floor where the hall call registration is made (hereinafter, sometimes referred to as “land hall call registration floor”). The car 4 other than the response car 4 once allocated as described above is predicted to arrive first, and the predicted arrival time (hereinafter referred to as “first car 4” in some cases) of this first car 4 is registered. When the predicted response time to the floor) is equal to or longer than a preset change allowable time, the first arrival car 4 is changed to the response car 4, and the lighting state of the forecast light 10 at each landing 8 is changed to respond. Response basket change control for changing the display of the basket 4 is executed. On the other hand, when the predicted arrival time of the first arrival basket 4 is shorter than the change allowable time, the group management control device 1 prohibits the response basket change control, that is, prohibits changing the first arrival basket 4 to the response basket 4 and responds. Changing the display of the basket 4 is prohibited.

  Here, the change allowable time is, for example, when the response car 4 is switched and the display of the response car 4 of the hall 8 is switched, and accordingly, the user moves to the hall 8 corresponding to the response car 4 after the change. Then, it is set and stored in advance according to the time when the user can get into the response car 4 after the change appropriately. That is, when it is assumed that the response basket 4 is changed, the change allowable time is from when the display of the response basket 4 is switched until the user moves toward the landing 8 corresponding to the changed response basket 4 and arrives. It is set according to the estimated travel time. That is, when the landing call registration from the landing 8 is performed, the group management control device 1 once assigns the response basket 4 responding to the landing call registration and then the first arrival basket 4 is generated. Based on the predicted travel time, it is determined whether to actually switch the response basket 4 to switch the display.

  That is, when the landing call registration from the landing 8 is performed, the group management control device 1 once allocates the response basket 4 responding to the landing call registration and then the first arrival basket 4 is generated. As the time until 4 actually arrives at the hall call registration floor, the time required for the user to move to the hall 8 corresponding to the changed response car 4 and to arrive after switching the display of the response car 4 Whether or not can be secured. And the group management control apparatus 1 changes the lighting state of the forecast light 10 of each hall 8 and changes the display of the response basket 4 when the travel time can be secured, while the travel time cannot be secured. In addition, the lighting state of the forecast light 10 at each landing 8 is maintained as it is, and the display of the response basket 4 is not changed. In other words, when the landing call registration from the landing 8 is made, the group management control device 1 once assigns the response basket 4 responding to the landing call registration and then the first arrival basket 4 occurs. The basket 4 that can secure the travel time from the first arrival basket 4 is defined as a response basket 4.

  Specifically, the group management control device 1, as illustrated in FIG. 1, includes a hall call detection processing unit 11, an allocation processing unit 12, a hall display control processing unit 13, a cage call first arrival detection processing unit 14, and a response basket change. Each functional configuration of the determination processing unit 15 and the like is provided. These functional configurations are realized by, for example, a program stored in a program ROM of the group management control device 1 being read out by the arithmetic unit (CPU) and loaded onto the main memory of the group management control device 1. The Note that these functional configurations are not necessarily realized in the group management control device 1 as all the functional configurations, and may be realized in a distributed manner on a plurality of hardware.

  The hall call detection processing unit 11 detects the hall call registration information in each unit control device 7 of each unit when the hall call registration from the hall 8 is performed. When the hall call registration is performed at the hall 8 of each unit via the hall call button 5, the hall call registration information is input from the hall call button 5 to the hall call detection processing unit 11 via the single controller 7. The Then, the hall call detection processing unit 11 outputs the hall call registration information of each unit to the allocation processing unit 12.

  When the hall call registration from the hall 8 is made, the allocation processor 12 receives the hall call registration information of each car input from the hall call detection processor 11 and each car 4 input from each unit controller 7. Based on the car operation information or the like, the optimum response car 4 that responds to the hall call registration is judged and assigned. As described above, the allocation processing unit 12 predicts, for example, a car call registration signal, a hall call registration signal, outputs from various sensors and detectors, a current position and a moving direction (up-and-down direction) of the car 4, Based on the state of each elevator 3 and each car 4 such as a destination call, a car call, and a predicted destination floor, a response car 4 for the corresponding hall call registration is assigned. Then, the allocation processing unit 12 outputs a response command to one of the single control devices 7 corresponding to the allocated response basket 4 so as to respond to the corresponding hall call registration. Thereby, based on the response command input from the allocation processing unit 12, the single control device 7 moves the corresponding response basket 4 to the landing call registration floor and makes it land. At this time, the allocation processing unit 12 outputs response basket information to the hall display control processing unit 13 almost simultaneously with the output of the response command.

  The hall display control processing unit 13 controls driving of the hall display unit 6 of each hall 8. The hall display control processing unit 13 responds to the hall call with respect to any single control device 7 corresponding to the assigned response basket 4 based on the response basket information input from the assignment processing unit 12. A display command is output so that 4 is displayed on the hall 8. As a result, the single control device 7 turns on the forecast light 10 of the hall 8 corresponding to the corresponding response basket 4 based on the display command input from the hall display control processing unit 13.

  Based on the car operation information of each car 4, the car call first arrival detection processing unit 14 detects that a car 4 other than the response car 4 responds first to the landing call registration floor. Here, the phenomenon that the basket 4 other than the assigned response basket 4 arrives at the landing call registration floor first arrives at the landing call registration due to factors such as fluctuation factors caused by the user's operation, It may occur when the difference from the operation state becomes large. As a case where it is predicted that a car 4 other than the assigned response car 4 will arrive first on the hall call registration floor, for example, the hall call registration floor is provided in the car 4 via a car call button under a predetermined condition. May be registered as a basket call.

  For example, as illustrated in FIG. 2, a user operates a hall call button 5 to register a hall call in the DN (downward) direction, and for this hall call registration, Unit A is assigned as a response car 4. Suppose that the forecast light 10 in the DN direction at the landing 8 of this A-unit is turned on. And after the forecast light 10 of the landing 8 of Unit A is turned on, the driving situation of each car 4 changes, and the car 4 of this D unit is caused by the car call in the car 4 of the D unit. Assuming that the arrival of the landing call registration floor in the DN direction precedes the response car 4, the response car 4 must be changed from the car 4 of the A machine to the car 4 of the D car. In spite of the first arrival, the lighting of the forecast light 10 at the landing 8 of the Unit A may cause the user to wait for the cage 4 of the Unit A, resulting in a relatively long wait. . In addition, even if the user gets on either the car A or the car D, the other car 4 that is not on the vehicle becomes a useless response, so that the driving efficiency of the elevator group 2 as a whole deteriorates. There is a risk that.

  In addition, such a group management control device 1 may predict a car call that may be generated at the time of landing call registration when predicting a car operation situation, but is a response machine to which a user is initially assigned. The car call that was predicted to be registered in the Car 4 of the Unit A when it gets on the first Car D of the Car 4 instead of the Car 4 of the Unit A is actually registered in the Car 4 of the Unit A Instead, the car call is registered in the car 4 of the No. D machine that should not be registered, and the actual operation situation after that may be further different from the predicted operation situation.

  In the above example, for example, when the response basket 4 is changed from Unit A to Unit D, the forecast light 10 of Unit A is turned off, and the forecast light 10 of Unit D is turned on, the user As the forecast light 10 of the unit No. 10 is turned on, it moves from the platform 8 of the unit A to the platform 8 of the unit D. At this time, if the car 4 of the D machine completes the response to the landing call registration floor before the movement of the user D to the landing 8 is completed, the forecast light 10 of the D machine is turned on, The user who was moving towards the platform 8 of Unit D was unable to get on after the response car 4 was suddenly changed despite waiting for the arrival of the car 4 according to the forecast light 10 This may cause discomfort.

  Therefore, when the hall call registration from the hall 8 is performed, the group management control device 1 according to the present embodiment changes the response car under a predetermined condition by the car call first arrival detection processing unit 14 and the response car change determination processing unit 15. By executing the control, the response basket 4 can be changed in consideration of the travel time of the user, and the user can be guided by the forecast light 10 with a margin, thereby reducing the user's discomfort. The response basket 4 is changed while being reduced.

  The car call arrival detection processing unit 14 of the present embodiment typically has a car call in each car 4 based on the car operation information of each car 4 to the landing call registration floor prior to the response car 4. It is determined whether or not the first arrival basket 4 that arrives, that is, the first arrival basket 4 by the so-called first call arrival has occurred. The car call first arrival detection processing unit 14 monitors the car operation information of each car 4 and moves in the same direction as the registered hall call, and arrives at the corresponding hall call registration floor with the car call. For car 4, there is no unanswered hall call from the current position to the hall call registration floor (ie, the car call first arrival floor), and it is estimated that there is no change in the expected arrival time due to the added car call etc. If this occurs, it is predicted that the first call will occur. Then, the car call first arrival detection processing unit 14 determines and calculates a predicted arrival time of the first arrival car and the first arrival car 4 that arrives at the landing call registration floor, and includes the information on the first arrival machine and the predicted arrival time. The first arrival occurrence information is output to the response basket change determination processing unit 15. The car call first arrival detection processing unit 14 may be anything that can determine the presence or absence of the car 4 that arrives at the landing call registration floor prior to the response car 4. Other than the car call first arrival, for example, the door 9 You may make it determine the presence or absence of the first arrival basket 4 which arises due to extension of opening time, addition of hall call registration, or the like.

  Here, an example of the car call first arrival detection process by the car call first arrival detection processing unit 14 will be described with reference to the flowchart of FIG.

  First, the cage call first arrival detection processing unit 14 is driving in the same direction as the corresponding hall call, and the basket 4 to be determined for the cage call first arrival is not the response cage 4 for the hall call among the plurality of cages 4. It is determined whether or not (ST1).

  When the car call first arrival detection processing unit 14 determines that the car 4 to be determined for the car call first arrival is not the response car 4 for the hall call and is driving in the same direction as the corresponding hall call (ST1: Yes), it is determined whether or not the car call is registered on the same floor as the corresponding hall call in the car 4 to be determined for the first call arrival (ST2).

  When it is determined that the car call is registered on the same floor as the corresponding hall call in the target car 4 for which the car call first arrival is determined (ST2: Yes), the car call first arrival detection processing unit 14 determines the first call arrival. It is determined whether the target cage 4 is shorter than the response cage 4 assigned by the assignment processing unit 12 when the hall call registration is made, or the predicted arrival time at the hall call registration floor is shorter (ST3). .

  The basket call arrival detection processing unit 14 determines the basket call arrival when the target basket 4 for determining the basket call arrival is determined to have a shorter estimated arrival time at the landing call registration floor (ST3: Yes). It is determined whether or not the target car 4 is closer to the hall call registration floor than the preset position, and there is a low possibility that additional hall calls will occur in the future (ST4). The basket call arrival detection processing unit 14 learns, for example, the occurrence frequency per unit time of the hall call as statistical data, and determines the current position of the basket 4 for which the basket call arrival is determined, the determination target time zone, and the response. Based on the occurrence probability of the landing call, the basket 4 that is the target for determining the first call arrival determines whether or not there is a low possibility that additional landing calls will occur in the future.

  The basket call first arrival detection processing unit 14 determines that the basket call first arrival is determined as a target for determining the first call arrival when it is determined that there is a low possibility that additional landing calls will occur in the future (ST4: Yes). The basket 4 that has been made is set as a response basket change request candidate (ST5), and it is determined whether or not the determination of the first call arrival has been confirmed for all the baskets 4 subject to group management control (ST6).

  In ST1, the cage call first arrival detection processing unit 14 is the response cage 4 to the hall call for which the cage call first arrival is determined, or the hall call to which the target cage 4 for which the first call arrival is determined corresponds. If it is determined that the car is driving in the opposite direction (ST1: No), it is determined in ST2 that the car call is not registered on the same floor as the corresponding hall call in the target car 4 for which the car call first arrival is determined. If it is determined (ST2: No), if it is determined in ST3 that the target cage 4 for determining the first call arrival has less predicted arrival time at the landing call registration floor (ST3: No), ST4 When it is determined that there is a high possibility that a landing call will be additionally generated in the future (ST4: No), the determination of the first call arrival is performed for all the baskets 4 subject to group management control. The Determines whether the certification (ST6).

  If it is determined that the determination of the first call arrival has not been confirmed for all the baskets 4 subject to group management control (ST6: No), the basket call first arrival detection processing unit 14 returns to ST1 and repeatedly performs the subsequent determinations. To do. If the basket call first arrival detection processing unit 14 determines that the basket call first arrival determination has been confirmed for all the baskets 4 subject to group management control (ST6: Yes), this basket call first arrival detection process ends.

  Returning to FIG. 1, the response car change determination processing unit 15 is based on the car call first arrival information including the information on the first arrival machine and the predicted arrival time input from the car call first arrival detection processing unit 14 as described above. Request for change of response car 4 when the estimated arrival time of the car call first arrival car 4 detected as a response car change request candidate by the car call first arrival detection processing unit 14 to the landing call registration floor is more than the allowable change time. The response basket change request is output to the allocation processing unit 12.

  Here, an example of the response basket change determination process by the response basket change determination processing unit 15 will be described with reference to the flowchart of FIG.

  First, the response basket change determination processing unit 15 determines, from among the plurality of baskets 4, the first basket 4 for which a response basket change determination target is determined by the basket call first arrival detection processing unit 14 as a response basket change request candidate. It is determined whether or not (S21).

  When the response basket change determination processing unit 15 determines that the target basket 4 for which the response basket change is to be determined is the first response basket change request candidate 4 (ST21: Yes), the target basket for which the response basket change is determined. It is determined whether or not the estimated arrival time at the hall call registration floor No. 4 is secured for the change allowable time or more (ST22).

  If the response basket change determination processing unit 15 determines that the predicted arrival time at the landing call registration floor of the basket 4 for which the response basket change is to be determined is secured for the change allowable time or more (ST22: Yes), the response basket It is determined whether or not the basket 4 to be changed is the shortest predicted arrival time at the landing call registration floor among the first arrival baskets 4 of the response basket change request candidates (ST23).

  The response car change determination processing unit 15 determines that the target car 4 for which the response car change is to be determined is the shortest predicted arrival time at the landing call registration floor in the response car change request candidate first arrival car 4. If this is the case (ST23: Yes), it is assumed that the target basket 4 for which the response basket change is to be determined is the first arrival basket 4 for which the response basket change request is made (ST24), and the response basket change determination is made for all the response basket change request candidate baskets 4. It is determined whether or not it has been confirmed (ST25).

  If the response basket change determination processing unit 15 determines in ST21 that the target basket 4 for which the response basket change is to be determined is not the first arrival basket 4 of the response basket change request candidate (ST21: No), the response basket is determined in ST22. When it is determined that the predicted arrival time of the target basket 4 to be changed to the hall call registration floor is not secured for the change allowable time or more (ST22: No), the target basket 4 for which the response basket change is determined in ST23. If it is determined that the estimated arrival time at the landing call registration floor is not the shortest in the first arrival basket 4 of the response basket change request candidates (ST23: No), the response basket change determination is made for all of the response basket change request candidates. It is determined whether or not the basket 4 has been confirmed (ST25).

  If the response basket change determination processing unit 15 determines that the response basket change determination has not been confirmed for all the response basket change request candidates (ST25: No), it returns to ST21 and repeats the subsequent determinations. Execute. When the response basket change determination processing unit 15 determines that the response basket change determination has been confirmed for all the baskets 4 of the response basket change request candidates (ST25: Yes), the response basket change determination processing ends.

  Then, the allocation processing unit 12 changes the response command and the response basket information based on the response basket change request input from the response basket change determination processing unit 15, and sends a response basket change request via each single control device 7. The first arrival car 4 to be changed is changed to a new response car 4 and the forecast of the hall display unit 6 of the hall 8 corresponding to the response car 4 initially assigned via the hall display control processing unit 13 and each single control device 7. The lamp 10 is turned off, and the forecast lamp 10 of the hall display section 6 of the hall 8 corresponding to the newly assigned changed response basket 4 is turned on.

  Therefore, when the hall call registration from the hall 8 is performed, the group management control device 1 is a first-arrival car that is predicted to arrive at the hall call registration floor rather than the assigned response car 4 once. When the predicted arrival time of 4 is equal to or longer than the allowable change time, the response basket change control is executed to change the response basket 4 in consideration of the moving time of the user. Since the user can be guided to the hall 8 of the response car 4 after the change, the car 4 that responds appropriately by the hall 8 can be displayed. Thereby, this group management control device 1 can change the response basket 4 while reducing the user's discomfort, and can improve the operation efficiency. It is possible to achieve both a reduction in discomfort for the user and an improvement in operation efficiency.

  That is, the group management control device 1 once assigns the response car 4 to the hall call registration, and after the forecast light 10 of the corresponding hall 8 is turned on, the driving situation of each car 4 changes and the predetermined condition is reached. When the first arrival basket 4 that satisfies the condition is generated, the time that the user waits for the basket 4 can be relatively shortened by changing the first arrival basket 4 to the response basket 4. Thereby, the group management control device 1 can prevent, for example, either the response basket 4 before the change or the first arrival basket 4 from being a useless response, and as a result, in the elevator group 2 as a whole. Operation efficiency can be improved. Further, the group management control device 1 changes the first arrival basket 4 to the response basket 4 when the first arrival basket 4 that satisfies the predetermined condition is generated, so that, for example, the predicted basket call is the response basket before the change. Instead of being registered in 4, instead of being registered in the first-arrival basket 4 where the car call should not be registered, the actual operation situation after that will differ greatly from the predicted operation situation For example, it is possible to suppress adverse effects on other hall calls.

  At this time, the group management control device 1 changes the first arrival car 4 to the response car 4 on the condition that the predicted arrival time of the first arrival car 4 is equal to or longer than the allowable change time, and displays the response car 4 on the landing 8. By changing, it is possible to prevent the response car 4 from completing the response to the hall call registration floor before the movement to the hall 8 corresponding to the response car 4 after the change of the user is completed. This can reduce user discomfort. As a result, the group management control device 1 changes the lighting of the forecast light 10 to cause a situation in which the user who has moved toward the changed hall 8 cannot get on the response car 4. In addition, it is possible to prevent the hall call from being made again without entering the response car 4, and in this respect as well, the driving efficiency of the entire elevator group 2 can be improved.

  The group management control device 1 configured as described above assigns the car 4 responding to the hall call registration from the hall 8 of the elevator 3 according to the state of each car 4 from the plurality of cars 4 of the elevator 3. The group management control for displaying the responding car 4 on the hall 8 is executed, and it is predicted that a car 4 other than the responding car 4 will arrive first on the floor where the hall call registration has been made, and the estimated arrival time of the car 4 that arrives first When it is longer than the change allowable time set in advance, the car 4 that arrives first is changed to the car 4 that responds, and response car change control is executed to change the display of the car 4 that responds.

  Therefore, the group management control device 1 can both reduce the user's discomfort and improve the operation efficiency, and can display the car 4 responding to the landing 8 more appropriately.

  It should be noted that the change allowable time described above may be changed according to various conditions. For example, the response basket change determination processing unit 15 may change the change allowable time according to the type of the hall call such as the general hall call or the wheelchair hall call. Thereby, for example, the group management control device 1 is predicted by setting the change allowable time relatively longer when a wheelchair landing call is made than when a general landing call is made. Corresponding to the difference in the movement speed (movement time) of the user, it is possible to set an appropriate change allowable time, thereby improving the change accuracy of the response basket 4 and more preferably reducing the user's discomfort. And improvement of operation efficiency.

  In addition, the response basket change determination processing unit 15 allows change based on, for example, the positional relationship between the landing 8 corresponding to the response basket 4 before being changed by the response basket change control and the landing 8 corresponding to the first arrival basket 4. You may make it change time. The travel time from the hall 8 corresponding to the response car 4 before the change to the hall 8 corresponding to the response car 4 after the change typically changes according to the positional relationship of the two halls 8 on the plan view. There is a tendency. For example, as shown in FIG. 2, when the response basket 4 before the change is the A machine, if the response basket 4 after the change is the B machine, the moving distance of the user is the distance L1. If the response basket 4 after the change is the D machine, the moving distance of the user is a distance L2 longer than the distance L1, and the moving time of the user tends to be longer correspondingly.

  For this reason, the response basket change determination processing unit 15 makes the change allowable time relatively long when the distance between the two halls 8 is relatively long, for example, as the change allowable time correction process, while the two halls 8 When the distance between them is relatively short, the change permissible time is made relatively short. In other words, when comparing the predicted arrival time of the first arrival basket 4 and the change allowable time, the response basket change determination processing unit 15 sets the change allowable time according to the combination of the response basket 4 before the change and the first arrival basket 4. change. Thereby, the group management control device 1 sets an appropriate change allowable time, for example, based on the positional relationship between the hall 8 corresponding to the response basket 4 before the change and the hall 8 corresponding to the first arrival basket 4. Therefore, it is possible to improve the accuracy of changing the response basket, and more appropriately reduce the user's discomfort and improve the operation efficiency.

  In addition, the response basket change determination processing unit 15, for example, as a change allowable time learning process, the response basket 4 is landed on the floor where the landing call registration has been made, and this response basket 4 door 9 is opened from this time You may make it learn change allowable time based on the time until the time of the load of the response basket 4 changing. The response basket change determination processing unit 15, for example, from the time when the door 9 of the response car 4 is opened to the time when the load of the response car 4 changes based on the detection result of the load by the load detector of the car 4. Detect time. The time from when the door 9 of the response car 4 is opened to when the load of the response car 4 changes depends on the time required for the user to actually get into the answer car 4 at the landing call response. It tends to be a long time. For this reason, the response basket change determination processing unit 15, for example, as a change allowable time learning process, starts when the response basket 4 has landed on the floor where the hall call registration has been made and the door 9 of the response basket 4 is opened. By learning the change allowable time based on the time until the load of the response basket 4 changes, it is possible to set a more appropriate change allowable time, thereby improving the change accuracy of the response basket, It is possible to achieve both a reduction in user discomfort and an improvement in operation efficiency.

[Embodiment 2]
FIG. 5 is a block diagram illustrating a functional configuration of the group management control device according to the second embodiment. The elevator group management control device according to the second embodiment differs from the first embodiment in that it includes a response command suppression processing unit. In addition, about the structure, operation | movement, and effect which are common in embodiment mentioned above, the overlapping description is abbreviate | omitted as much as possible.

  The group management control device 201 as the elevator group management control device of the present embodiment shown in FIG. 5 prohibits the response car 4 after being changed by the response car change control from responding to other hall call registration. Specifically, the group management control device 201 includes a hall call detection processing unit 11, an allocation processing unit 12, a hall display control processing unit 13, a car call arrival detection processing unit 14, a response basket change determination processing unit 15, and the like. Furthermore, each function structure of the response command suppression process part 216 is provided.

  The response command suppression processing unit 216 suppresses the response command by the allocation processing unit 12 according to a predetermined condition after being changed by the response basket change control. The response command suppression processing unit 216 changes the response basket 4 by the response basket change control based on the response basket change request input from the response basket change determination processing unit 15, the candidate basket information input from the allocation processing unit 12, and the like. In this case, the response car 4 after this change is prohibited from responding to other hall call registration, and the response command for the forward hall call up to the hall call registration floor is sent to the response car 4 after the change. Suppress the addition.

  Here, the candidate car information is information relating to a candidate car 4 that responds to another hall call registration newly generated after the response car 4 is changed. The allocation processing unit 12 outputs candidate cage information to the response command suppression processing unit 216 when selecting a candidate cage 4 that responds to another landing call registration newly generated after the response cage 4 is changed. Then, the response command suppression processing unit 216 is a first arrival basket 4 in which the candidate cage 4 corresponding to the candidate cage information is a new response cage 4, and a newly generated hall call is generated from the current position of the first arrival basket 4. If it is a forward hall call up to the hall call registration floor, response processing information indicating that this candidate car 4 is not allowed to respond to other newly created hall call registration is assigned to the allocation processing unit. 12 is output. If the response by the candidate basket 4 is not permitted based on the response permission information input from the response command suppression processing unit 216, the allocation processing unit 12 responds to a response to the cage 4 other than the candidate cage 4. And response basket information is output. Thereby, the group management control device 201 can prohibit the response cage 4 after being changed by the response cage change control from responding to other hall call registration.

  The group management control device 201 configured as described above can achieve both a reduction in user discomfort and an improvement in operation efficiency, and can display the car 4 responding to the landing 8 more appropriately. . Then, the group management control device 201 of the present embodiment prohibits the response cage 4 after being changed by the response cage change control as described above from responding to other hall call registration, so that the response cage 4 It is possible to prevent the first-arrival basket 4 from changing again due to a newly registered hall call after the change, thereby more appropriately reducing the user's discomfort and improving the operation efficiency. be able to.

  According to the elevator group management control device according to the embodiment and the modification described above, the car responding to the landing more appropriately can be displayed.
