  Here, in the conventional elevator, what controls the operation of an elevator by switching several operation modes, such as VIP driving | operation and a fully automatic driving | operation, is known, for example. However, in the prior art of Patent Document 1, since such an operation mode is not considered at all, there is a possibility that the traveling speed of the car in the operation mode with a high priority may be reduced. For this reason, the driving efficiency of the car in the high-priority operation mode is reduced, or the user of the car in the high-priority operation mode is uncomfortable.

Embodiment 1 FIG.
FIGS. 1 to 3 relate to Embodiment 1 of the present invention. FIG. 1 is a diagram schematically illustrating the overall configuration of the elevator group management control device, and FIG. 2 is a priority ranking for each operation mode. FIG. 3 is a flowchart for explaining the operation of the elevator group management control device.

  In FIG. 1, an elevator to which a group management control device according to Embodiment 1 of the present invention is applied includes a plurality of cars 1. The plurality of cars 1 are arranged adjacent to each other. Moreover, these several cage | basket | cars 1 can raise / lower the inside of the hoistway which is not shown in figure mutually independently.

  The operation of these cars 1 is controlled by each car management device 10. Each table management device 10 is provided in correspondence with each of the plurality of cars 1. That is, the same number of each car management device 10 as the car 1 is provided. Each vehicle management device 10 is provided with a travel control unit 11. The traveling control unit 11 controls traveling of the car 1 corresponding to each.

  A group management device 20 is provided as a host device of each of the vehicle management devices 10. The group management device 20 is for managing a plurality of cars 1 as a group.

  A landing button 2 is installed at each floor where the car 1 can be stopped. These hall buttons 2 are used by elevator users to register hall calls. When the user operates the landing button 2, an operation signal is output from the operated landing button 2 to the group management device 20. Upon receiving this operation signal, the group management device 20 registers a hall call to the floor where the hall button 2 from which the operation signal is output is installed.

  The group management apparatus 20 is provided with an allocation control unit 21. The assignment control unit 21 determines a car 1 to be assigned to a hall call registered by operating the hall button 2 from among the plurality of cars 1. The determination of the car 1 to be assigned to the hall call is performed as follows. First, the allocation control unit 21 calculates an evaluation value for each car 1 based on the operation state of each car 1. Then, the assignment control unit 21 compares the calculated evaluation values for each car 1, and determines the car 1 having the smallest evaluation value to be assigned to the hall call.

  When the car 1 to be assigned to the hall call is determined in this way, the assignment information is transmitted from the group management device 20 to each vehicle management device 10 that controls the car 1. Then, the traveling control unit 11 of each vehicle management device 10 that has received the allocation information travels the car 1 to the floor where the hall call is registered in order to respond to the registered hall call according to the received allocation information. Let

  The traveling control unit 11 of each vehicle management device 10 selects one of a plurality of operation modes having different priorities, and controls the traveling of the car 1 according to the selected operation mode. Examples of the plurality of operation modes having different priorities include VIP operation, operation with a driver, independent operation, fully automatic operation, and the like. The VIP operation is an operation mode in which a key person is transported to the destination floor with the highest priority. Driving with a driver is a driving mode in which a driver gets on the car 1 and the car 1 is manually driven by the operation of the driver.

  The independent operation is an operation mode in which the target car 1 is made to travel independently from a group under the control of the group management device 20. In the VIP operation and the driver-operated operation described above, the target car 1 travels independently from the group. The fully automatic operation is an operation mode in which the car 1 is automatically assigned to a call and travels to the destination floor under the management of the group management device 20.

  In this manner, under the management of the group management device 20, the traveling of the plurality of cars 1 is controlled according to the currently selected operation mode under the control of each of the vehicle management devices 10 (travel control unit 11). The group management apparatus 20 further includes a passing prediction unit 22, a priority comparison unit 23, a storage unit 24, and a speed reduction command output unit 25.

  The passing prediction unit 22 predicts the occurrence of passing between two cars 1 adjacent to each other among the plurality of cars 1. Here, “passing” refers to an event in which two cars 1 that are adjacent to each other and run in opposite directions pass through the same place in the lifting / lowering stroke at the same time. The prediction of the occurrence of passing by the passing prediction unit 22 is performed based on the operation state of the plurality of cars 1.

  The priority comparison unit 23 compares the priority of the operation mode with respect to the two cars 1 in which the occurrence of the passing is predicted by the passing prediction unit 22. Here, as described above, the operation mode of the car 1 includes, for example, VIP operation, operation with a driver, independent operation, fully automatic operation, and the like. In these plurality of operation modes, priority is set which is a degree of giving priority to the operation of the car 1 in which operation mode over the car 1 in other operation modes. The plurality of operation modes are ranked from the highest priority to the lowest according to the priority set for each.

  The storage unit 24 of the group management device 20 stores information related to the priority order of operation modes in advance. An example of the information regarding the priority order of the operation modes stored in the storage unit 24 is shown in FIG. In FIG. 2, the higher the priority is, the lower the priority is. In the example of FIG. 2, the VIP operation has the highest priority, and then the driver-operated operation and the independent operation have the highest priority. Other operation modes including fully automatic operation have the lowest priority.

  Note that the information regarding the order of priority of the operation modes stored in the storage unit 24 can be appropriately changed by an administrator or the like as necessary. By updating the information stored in the storage unit 24, it is possible to change the priority order in a plurality of operation modes.

  The priority comparison unit 23 compares the priority of the operation mode with reference to the information stored in the storage unit 24 for the two cars 1 for which the occurrence of the passing is predicted by the passing prediction unit 22. Then, from the comparison result, the car 1 having the lower priority of the operation mode than the other of the two cars 1 is determined.

  The speed reduction command output unit 25 outputs a speed reduction command to each of the vehicle management devices 10 that control one of the cars 1 that has been determined by the priority comparison unit 23 that the priority of the operation mode is lower than the other. Receiving this speed reduction command, the traveling control unit 11 of each of the vehicle management devices 10 reduces the traveling speed of the car 1 controlled by itself from a predetermined speed.

  The decrease in the traveling speed is performed at least while passing the portion where the occurrence of the passing is predicted by the passing prediction unit 22. That is, it is preferable from the viewpoint of driving efficiency that the traveling speed is reduced immediately before the passing occurs and is returned to the original traveling speed immediately after the passing is completed.

Next, the flow of operation of the elevator group management control apparatus configured as described above will be described once again with reference to the flowchart of FIG.
First, in step S <b> 1, the passing prediction unit 22 predicts whether or not a passing of two cars 1 adjacent to each other occurs based on operation information of the plurality of cars 1. If it is predicted in step S1 that two adjacent cars 1 have passed each other, the process proceeds to step S2.

  In step S2, the priority comparison unit 23 refers to the information stored in the storage unit 24, and compares the priorities of the operation modes of the two cars 1 that are predicted to pass each other in step S1. Then, from the comparison result, the car 1 having the lower priority of the operation mode than the other of the two cars 1 is determined.

  In subsequent step S3, the speed reduction command output unit 25 outputs a speed reduction command to each of the car management devices 10 that control the car 1 that has been determined in step S2 that the priority of the operation mode is lower than the other. Thus, a series of operation flows is completed.

  The elevator group management control device configured as described above is an elevator group management control device that manages a plurality of cars that can travel independently of each other as a group, and has a plurality of operation modes with different priorities. A traveling control unit that controls the traveling of each car according to the operation mode selected from the above, a passing prediction unit that predicts occurrence of passing between two adjacent cars among a plurality of cars, and priority of the plurality of operating modes Comparing the priority of the operation mode for both the storage unit that stores information related to the rank of the degree in advance and the two cars that are predicted to pass each other by the passing prediction unit based on the information stored in the storage unit Driving control that controls one of the two cars, the driving mode of which is determined to be low by comparison in the priority comparing unit. A speed reducing instruction output unit for outputting a speed reducing instruction to, those having a.

  Therefore, according to the priority of the operation mode of each car, at the time of passing, the traveling speed of the lower priority car can be reduced and the traveling speed of the lower priority car can be maintained. For this reason, it is possible to suppress the occurrence of a wind pressure change at the time of passing without reducing the operation efficiency of the car having a high priority of the operation mode. In addition, there is no discomfort for the user of the car having the high priority of the operation mode.

Embodiment 2. FIG.
FIG. 4 is a flowchart for explaining the operation of the elevator group management control apparatus according to Embodiment 2 of the present invention.

  In the configuration of the first embodiment described above, when there is a new hall call registration request, the car assigned to the newly registered hall call is determined based on the evaluation value. At this time, by assigning a new car to the hall call registration, there is a possibility that a difference between the car and the adjacent car adjacent to the car occurs.

  Therefore, in the second embodiment described here, if it is predicted that a car will be newly assigned to a hall call and a passing car will be adjacent to the car, one of the car and the car adjacent to the car will be used. The allocation of the car is changed.

  The elevator group management control apparatus according to the second embodiment has the same basic configuration as that of the first embodiment. Therefore, the configuration of the second embodiment will be described with reference to FIG. 1 used in the first embodiment.

  In FIG. 1, when the user operates the landing button 2, an operation signal is output from the operated landing button 2 to the group management device 20. Upon receiving this operation signal, the group management device 20 registers a hall call to the floor where the hall button 2 from which the operation signal is output is installed.

  The assignment control unit 21 of the group management device 20 calculates an evaluation value for each car 1 based on the operation state of each car 1 in order to determine the car 1 to be assigned to a newly registered hall call. Based on the calculated evaluation value, the car 1 to be assigned to the newly registered hall call is determined.

  The passing prediction unit 22 causes a car 1 (hereinafter referred to as a “newly assigned car”) assigned to a newly registered hall call to travel in response to the newly registered hall call, thereby newly assigning a car. It is predicted whether or not a new pass will occur between the car 1 and the car 1 adjacent to the newly assigned car (hereinafter referred to as “adjacent car”). If no passing is predicted, the allocation information is transmitted from the allocation control unit 21 to each of the car management devices 10 without changing the allocation of the car 1 to the new call registration.

  On the other hand, if it is predicted by the passing prediction unit 22 that a new passing will occur between each new assignment and each adjacent, the assignment control unit 21 attempts to change the assigned car 1 for the call registration. .

  The car 1 assigned to this call registration is changed as follows. First, when the passing prediction unit 22 predicts that a new passing occurs between each newly allocated car and each adjacent car, the priority comparing unit 23 calculates the priority of the operation mode of the newly assigned car and the adjacent car. Compare operation mode priorities. In this comparison, information related to the priority order of operation modes stored in advance in the storage unit 24 is referred to.

  The priority comparison unit 23 determines whether or not the priority of the operation mode of the newly assigned car is higher than the priority of the operation mode of the adjacent car based on the comparison result. If the priority of the operation mode of the newly assigned car is higher than the priority of the operation mode of the adjacent car, the call registration to which the adjacent car is assigned is the target of assignment change. On the other hand, if the priority of the operation mode of the newly assigned car is not higher than the priority of the operation mode of the adjacent car, the newly registered hall call is set as the assignment change target.

  The assignment control unit 21 determines whether or not it is possible to change the assignment to a car 1 other than the car 1 currently assigned to the call registration that is the assignment change target. If the assignment can be changed to another car 1, the assignment is changed. On the other hand, if the assignment cannot be changed to another car 1, the assignment is not changed.

  When changing the assignment, the car 1 assigned to the call registration to which the adjacent car is currently assigned has been changed in order to avoid the occurrence of passing again even though the assignment to the call registration has been changed. In this case, the car 1 to be assigned is selected from the cars 1 that are not adjacent to the newly assigned car. Similarly, when the car 1 assigned to the newly registered hall call is changed from the newly assigned car, the car 1 assigned from the car 1 not adjacent to the adjacent car is selected and determined.

  When the car 1 to be assigned to the hall call is determined in this way, the assignment information is transmitted from the group management device 20 to each vehicle management device 10. That is, in the event that the assignment has not finally changed, the assignment information is transmitted to each vehicle management apparatus 10 that controls the new assigned car. Further, when the car 1 assigned to the newly registered hall call is changed, the assignment information is transmitted to each of the car management devices 10 that control the car 1 after the change.

  Alternatively, when the car 1 assigned to the call registration to which the adjacent car is assigned is changed, each car management device 10 that controls the car 1 after the change and each car management device 10 that controls the newly assigned car. Allocation information is transmitted to each of these. In this case, in addition, information indicating that assignment to call registration has been canceled is transmitted to each of the car management devices 10 that control adjacent cars.

Next, the flow of operation of the elevator group management control apparatus configured as described above will be described once again with reference to the flowchart of FIG.
First, in step S11, when a new hall call in which the hall button 2 is operated is registered, in subsequent step S12, the allocation control unit 21 assigns the car 1 to the newly registered hall call. Performs assignment calculation.

  Then, the process proceeds to step S13, and the passing prediction unit 22 newly generates a passing for each new assignment assigned to the hall call newly registered in step S12 and for each adjacent car adjacent to the new assigned car. Predict whether or not. If no new occurrence of passing between the new allocation unit and the adjacent unit is predicted, the process proceeds to step S14, and information on the new allocation is output from the group management device 20 to each of the vehicle management devices 10.

  On the other hand, if it is predicted that a new allocation will occur and whether a new allocation will be adjacent or not, the process proceeds to step S15. In step S15, the priority comparison unit 23 determines whether or not the priority of the operation mode of the newly assigned car is higher than the priority of the operation mode of the adjacent car.

  If the priority of the operation mode of the newly assigned car is higher than the priority of the operation mode of the adjacent car, the process proceeds to step S16, and the call registration to which the adjacent car is assigned is set as the assignment change target. On the other hand, if the priority of the operation mode of the newly assigned car is not higher than the priority of the operation mode of the adjacent car, the process proceeds to step S17, and the newly registered hall call is set as the assignment change target.

  When the assignment change target is determined in step S16 or step S17, the process proceeds to step S18. In step S <b> 18, the assignment control unit 21 confirms whether or not the call registration whose assignment is to be changed can be assigned to another car 1.

  If the call registration whose allocation is to be changed can be assigned to another car 1, the process proceeds to step S19, and the assignment is changed to the other car 1. Then, the process proceeds to step S14, and the changed allocation information is output from the group management device 20 to each of the vehicle management devices 10.

On the other hand, if the call registration whose assignment is to be changed cannot be assigned to another car 1, the process proceeds to step S14 without changing the assignment, and a new assigned car is assigned to the new hall call registration. Information indicating that it has been received is output.
Other configurations and operations are the same as those in the first embodiment, and detailed description thereof is omitted.

  In the elevator group management control apparatus configured as described above, in the configuration of the first embodiment, the passing prediction unit is adjacent to the newly allocated car for each newly allocated car assigned to the new call registration. Predict the passing of adjacent cars. In addition, the priority comparison unit, when the passing prediction unit predicts the occurrence of passing for each newly allocated car and adjacent car, based on the information stored in the storage unit, the operation mode of the new allocated car and adjacent car Compare the priorities of. Then, the assignment control unit assigns the car to the call registration to which one of the newly assigned car and the adjacent car, which is determined to have a low priority in the operation mode by the comparison in the priority comparison part, is assigned. Is to change.

  For this reason, it is possible to suppress the occurrence of a difference between a car having a high priority in the operation mode and a car adjacent to the car, preventing a decrease in the operation efficiency of the car having a high priority in the operation mode, and Generation itself can be suppressed.

  Further, in the configuration described above, the assignment control unit is assigned one of the newly assigned car and the adjacent car that is determined to have a low operation mode priority by comparison in the priority comparison unit. The car assigned for call registration is changed to a car that is not adjacent to the other of the newly assigned car and the other car among the plurality of cars. For this reason, it is possible to more reliably avoid the occurrence of a difference between whether the priority of the operation mode is high and whether it is adjacent to the car.

Embodiment 3 FIG.
FIG. 5 relates to Embodiment 3 of the present invention, and schematically illustrates the overall configuration of the elevator group management control device.

  In the second embodiment described above, when a car is assigned to a new call registration, when a passing is predicted, a call registration in which one of the two cars in which the passing occurs is assigned. Was assigned to another car. That is, in the second embodiment, the assignment is changed if a pass occurs after the car is assigned once for call registration.

  On the other hand, in the third embodiment described here, when the priority of the operation mode of the car is higher than that of the car adjacent to the car with respect to a car, the call registration is made to the adjacent car from the beginning. By avoiding assigning, the occurrence of passing is suppressed.

  In FIG. 5, when the user operates the landing button 2, an operation signal is output from the operated landing button 2 to the group management device 20. Upon receiving this operation signal, the group management device 20 registers a hall call to the floor where the hall button 2 from which the operation signal is output is installed.

  The assignment control unit 21 of the group management device 20 calculates an evaluation value for each car 1 based on the operation state of each car 1 in order to determine the car 1 to be assigned to a newly registered hall call. Based on the calculated evaluation value, the car 1 to be assigned to the newly registered hall call is determined.

  At this time, the allocation control unit 21 refers to the information about the priority order of the operation mode stored in advance in the storage unit 24, and the priority of the operation mode is higher than the car 1 next to the car 1 with respect to the car 1. When there is a car 1 with a high degree, assignment of call registration to the car 1 is restricted. In other words, the assignment control unit 21 restricts the call registration assignment to the first car when the second car adjacent to the first car has a higher priority in the operation mode.

  For example, the assignment control unit 21 excludes the car 1 from the call registration assignment target as a restriction on the assignment of the call registration to the car 1. Alternatively, the allocation control unit 21 increases the evaluation value of the car 1 by multiplying a predetermined coefficient in calculating the evaluation value, thereby making it difficult for the car 1 to be selected as the allocation car.

  When the car 1 of interest is changed, the assignment control unit 21 assigns the car 1 priority to the car 1 relative to the car 1 adjacent to the car 1 when assigning the car 1 to the call registration. In other words, the call registration with respect to the adjacent car 1 can be paraphrased as the allocation is limited.

Other configurations and operations are the same as those in the first embodiment, and a detailed description thereof will be omitted.
Here, as described in the first embodiment, the traveling control unit 11 of each of the vehicle management devices 10 controls the traveling of the car 1 according to the operation mode selected from the plurality of operation modes having different priorities. Switching of the operation mode in the travel control unit 11 may be performed manually by an operation of an administrator, maintenance personnel, or the like. Alternatively, the traveling control unit 11 may automatically switch the operation mode according to a preset schedule.

  When the operation mode is automatically switched in accordance with a preset schedule, the assignment control unit 21 applies the switching of the operation mode ahead of the set schedule by a predetermined time. As an example, the car 1 to be assigned to the newly registered hall call is restricted.

  In other words, the allocation control unit 21 determines that the priority of the operation mode of the adjacent second car scheduled after a certain time in the set schedule is higher than the priority of the operation mode of the first car. In some cases, restrict the assignment of call registration to the first car.

  For example, in the schedule set for a certain car 1, when switching from a low-priority operation mode to a high-priority operation mode is scheduled, the operation is performed with a certain time margin from this scheduled operation mode switching time. Prior to mode switching, restriction of call assignment to the car 1 adjacent to the car 1 is started.

  In this way, a call is assigned to an adjacent car immediately before the operation mode switching of a certain car 1, thereby preventing a pass from occurring after the operation mode switching of the car 1 and more reliably. It is possible to avoid a difference between the car 1 and the adjacent car in the high-priority operation mode.

  In the elevator group management control apparatus configured as described above, in the configuration of the first embodiment, the assignment control unit refers to the information stored in the storage unit, and the first car among the plurality of cars is referred to. When the operation mode of the adjacent second car is higher than the priority of the operation mode of the first car, the assignment of call registration to the first car is restricted.

  For this reason, as in the second embodiment, it is possible to suppress the occurrence of a difference between the car having a high priority in the operation mode and the car adjacent to the car, and the driving efficiency of the car having the high priority in the operation mode. While preventing a fall, generation | occurrence | production of passing itself can be suppressed.

  The present invention manages a plurality of cars that can travel independently of each other as a group, and manages a group of elevators that control the traveling of each car according to an operation mode selected from a plurality of operation modes having different priorities. Can be used for control devices.
