Description

  The present invention relates to a group management control apparatus and method for operating and managing a plurality of elevators having different non-stop floors.

  In group management control that manages the operation of multiple elevators, the standby elevators that are not in use are distributed and waited on appropriate floors in preparation for the occurrence of demand, in accordance with the usage status of the building, improving convenience. Yes. For example, an elevator that is not used is made to wait on a floor designated in advance or a floor where congestion is predicted to shorten the waiting time when demand occurs.

  For example, Japanese Patent Application Laid-Open No. H10-228688 discloses dispersive standby for each preset zone and preferentially wait for distribution over a zone with a low service level.

Japanese Patent Laid-Open No. 3-177276

  Inconvenience arises when a plurality of elevators having different non-stop floors are made to wait on a floor close to the non-stop floor. In other words, the shift from the quiet time zone to the time of traffic demand generation time, the call waiting at the non-stop floor of the distributed standby elevator in that zone cannot be serviced by this distributed standby elevator, and the waiting time at the landing is long. turn into.

  An object of the present invention is to provide an elevator group management control apparatus and method that can reduce waiting time at a landing when traffic demand occurs when a plurality of elevators having different non-stop floors are group-controlled. It is to be.

  In a preferred embodiment of the present invention, in a group management control of an elevator in which a plurality of elevators having at least one non-stop floor different from that of the other one are determined to be on standby and are placed on standby, the dispersible elevators are distributed on standby. A plurality of zones to be determined are determined, and for each distributed standby zone, a standby elevator having the least non-stop floor in the corresponding zone is selected and determined as a distributed standby elevator. For each of the distributed standby zones, One floor is determined as the distributed standby floor of the zone.

  Also, in a preferred embodiment of the present invention, for each of the distributed standby zones, when determining one floor in the zone as the distributed standby floor of the zone, distributed standby is performed on a floor that is not adjacent to the non-stop floor. Let

  Further, in a preferred embodiment of the present invention, in the elevator group management control in which a plurality of elevators having at least one non-stop floor different from the other one determine a standby standby floor and wait, Divide almost evenly by the number of distributable elevators, determine the decentralized standby zones to wait for each distributable elevator one by one, and for each of the distributed standby zones, wait with the least number of non-stop floors in the corresponding zone An elevator is selected and determined as a distributed standby elevator, and for each of the distributed standby zones, a central zone in the zone or a floor that is not adjacent to a non-stopped floor of the elevator that has high traffic demand and is waiting is set as the distributed standby floor of the zone. decide.

  According to a preferred embodiment of the present invention, it is possible to reduce the waiting time for hall calls that occur on uneven floors.

  For example, in a floor zone including a floor where one of the elevators cannot be stopped, a quick response can be made to a hall call generated from this floor by waiting for an elevator that can service this floor.

  In addition, the present invention can perform operation in accordance with the number of elevators in the group and the stop floor when a plurality of elevators are grouped in a large-scale building or the like and the stop floor is different for each group to increase the operation efficiency. .

  For example, in a building that manages 6 elevators, if 3 units are responded to the hall call of the lower layer and 3 units are in the upper layer, only the stop floors are considered for each of the lower and upper units. The distributed standby elevators are distributed.

  Other objects and features of the present invention will be made clear in the embodiments described below.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram of an elevator group management control apparatus according to Embodiment 1 of the present invention.

  FIG. 1 shows a group management control device 1 that performs group management of three elevators. Each of the three elevators is controlled by elevator control devices 21 to 23, respectively. Each of the elevator control devices 21 to 23 transmits state signals such as the position of the elevator, the door state, and the call holding status to the group management control device 1. The group management control apparatus 1 includes a standby elevator service floor detection unit 3, a distributed standby zone determination unit 4, a distributed standby elevator determination unit 5 for each zone, a distributed standby floor determination unit 6 for each zone, and a distributed standby control unit 7. I have.

  The service level detection means 3 of the standby elevator detects an idle state, that is, a standby elevator, and also detects a service level (in other words, a non-stop floor) of the standby elevator. In this embodiment, the distributed standby zone determination means 4 divides all service floors of all standby elevators almost equally by the number of standby elevators, and determines the distributed standby zone. The distributed standby elevator determining means 5 for each zone selects an appropriate car from the elevators having the largest number of serviceable floors in the zone based on information on the serviceable floors of the distributed standby target elevators. In other words, the elevator having the highest serviceable floor in the zone is the elevator having the least non-stop floor in the zone. The distributed standby floor determining means 6 for each zone determines the standby floor in the target zone in consideration of the determined state signal of the distributed standby target elevator, the service floor in the zone, and the traffic demand of each floor in the zone. Determine and output to the distributed standby control means 7. In this embodiment, a floor that is not adjacent to the non-stop floor of the corresponding elevator and is close to the center of the zone or has a large traffic demand is determined as a distributed standby floor. The distributed standby control means 7 outputs a distributed standby command to the distributed standby target elevator and dispatches each elevator to each distributed standby floor.

  Next, a specific operation according to the first embodiment of the present invention will be described with reference to FIGS.

  FIG. 2 is a flowchart showing the distributed standby control operation according to the first embodiment of the present invention.

  FIG. 3 is an image diagram illustrating an example of a distributed standby control operation according to the first embodiment of the present invention.

  As shown in FIG. 3, Units 1 to 3 elevators are installed in the B2 to 10th floor buildings. The first floor is the basement floor B1 to B2, and the second unit is 9 to 10th floor. Assume that the units are B1 to B2 and 9 to 10 floors.

  According to the conventional distributed standby control, as shown in FIG. 3A, the first machine may be distributed on the first floor, the second machine on the eighth floor, and the third machine on the first floor. In this case, for a hall call that occurs on the 9th to 10th floors, the first unit waiting on the far 1st floor has to be serviced, which increases the waiting time. Similarly, for the underground floors B1 and B2, the second machine waiting on the far 8th floor has to service, and the waiting time becomes long.

  In the first embodiment of the present invention, such inconvenience associated with the presence of a non-stop floor can be solved. This will be described with reference to FIGS. 1, 2 and 3B.

  The service level detector 3 of the standby elevator in FIG. 1 detects the standby elevator from the status signals of each elevator output from the elevator control devices 21 to 23 (step 201 in FIG. 2), and the serviceable floor of each standby elevator. (In other words, a non-stop floor) is detected (step 202). If the standby elevator is not detected, the processing routine of FIG. 2 is terminated.

  The distributed standby zone determination means 4 divides the serviceable floors B2 to 10th floors of all standby elevators almost evenly with 3 dispersible units, and in the example of FIG. (Step 203). Next, the distributed standby elevator determining means 5 for each zone compares the number of serviceable floors of all the standby elevators in each zone, and distributes the standby elevator having the largest number of serviceable floors to that zone. A candidate for waiting is set (step 204). In other words, the standby elevator with the least number of non-stop floors in the zone is set as a candidate for a distributed standby target elevator to the zone. In the example of FIG. 3B, since the lower zone is No. 2 machine and the upper zone is No. 1 machine, the middle zone is automatically determined with No. 3 machine as the distributed standby machine.

  Here, unlike the above example, when there are a plurality of elevators having the same conditions as candidates for the distributed standby target elevator (step 205), the elevator with the shortest distance to the standby floor is selected as the distributed standby target elevator. (Step 206). If the serviceable floors of Unit 2 and Unit 3 are the same as shown in FIG. 3 (C), the operation distance to the distributed standby floor will be shorter for determining the standby standby floor for the lower and middle zones. , And wait for dispersion as shown in FIG.

  Thus, after determining the distributed standby elevator of each zone, the standby floor in the zone to be distributed standby is determined and created (step 207). As described above, it is desirable that the standby floor is a floor adjacent to the non-stop floor of the corresponding elevator, and the floor in the zone or near the center, or the floor with the highest traffic demand.

  Finally, the distributed standby control means 7 dispatches the determined distributed standby target elevators to the distributed standby floor determined for each zone (step 208).

  According to the above embodiment, the vehicle is dispatched so that there is no non-stop floor around the waiting elevator, and the waiting time can be shortened even for a hall call that occurs on uneven floors. Distributed standby control can be realized.

  Next, a second embodiment of the present invention will be described in detail with reference to FIGS.

  FIG. 4 is a block diagram of an elevator group management control apparatus according to Embodiment 2 of the present invention.

  FIG. 4 shows a group management control device 11 that performs group management of three elevators. Each of the three elevators is controlled by elevator control devices 21 to 23, respectively. Each of the elevator control devices 21 to 23 transmits state signals such as an elevator position, a door state, and a call holding state to the group management control device 11. The group management control device 11 includes a quiet time zone detection means 8, a stop / non-stop floor detection means 9, and a distributed standby floor determination means 10.

  The quiet time zone detection means 8 determines whether or not the current traffic demand is quiet based on the status signal of each elevator. The stop / non-stop floor detection means 9 divides the serviceable floors of all the standby elevators by the number of distributable units from the standby elevator status signal, and the stop and non-stop floors of each elevator in each zone. Is output to the distributed standby floor determination means 10. The distributed standby floor determination means 10 determines whether or not to change the standby position of the standby elevator based on the status signal of the standby elevator and the stopped floor and non-stop floor information in each zone.

  Next, the operation of the second embodiment will be described.

  FIG. 5 is a flowchart showing an operation according to the second embodiment of the present invention.

  FIG. 6 is an image diagram illustrating an example of a distributed standby control operation according to the second embodiment of the present invention.

  As shown in FIG. 6, Units 1 to 3 elevators are installed in the B2 to 10th floor buildings. As the non-stop floor, Unit 1 is the basement floor B2, and Unit 3 is the top floor 10th floor. Assume.

  The off-hour detection unit 8 determines whether or not all elevators in the group management group are in the standby elevator state and have maintained the state for a certain time or more from the state of each elevator output from the elevator control devices 21 to 23. Is determined (step 501 in FIG. 5). When the quiet time zone is not detected, the processing routine of FIG. 5 is terminated. When the above conditions are satisfied, the stop / non-stop floor detection means 9 detects the serviceable floors of the standby elevator (step 502), and divides the serviceable floors of all the standby elevators by the number of distributable units. The created zone is created (step 503). Further, the stop floor and the non-stop floor of each elevator in each zone are detected and output to the distributed standby floor determination means 10.

  The distributed standby floor determination means 10 detects whether there is an elevator waiting in each zone and whether there is a non-stop floor of the elevator (step 504). If there is no non-stop floor, the processing routine of FIG. 5 is terminated.

  If there is a non-stop floor of the standby elevator No. 1 in the zone Z1, it is determined whether there is another elevator that can be stopped on all floors in the zone Z1 (step 505). In the example of FIG. 6, both No. 2 and No. 3 are elevators that can be stopped on all floors in the zone Z1. If there is no elevator that satisfies this condition, the processing routine of FIG. 5 is terminated.

  When elevators No. 2 and No. 3 that can be stopped on all floors in the zone Z1 are detected, in the zones Z2 and Z3 in which these elevators are waiting, there are unstopped floors of those elevators No. 2 and No. 3. It is determined whether or not there is (step 506). If there is no non-stop floor, the processing routine of FIG. 5 is terminated.

  In the example of FIG. 6A, there is a non-stop floor of the elevator No. 3 in the zone Z3 where the elevator No. 3 that can be stopped on all floors in the zone Z1 is waiting. Therefore, the determination in step 505 is YES, and the process proceeds to step 507, where the elevators 1 and 2 are exchanged at the distributed standby floor as shown by the arrows in FIG.

  FIG. 6B shows the present invention in a distributed standby system in which two units are placed on standby in the lower zone Z1, preferably the first floor of the reference floor, and one remaining in the upper zone Z3 is placed on standby in group management of three units. It is an image figure at the time of applying. As shown in the figure, the difference from FIG. 6 (A) is that Unit 2 stands by in the lower zone Z1, and Units 1 and 3 located at the positions indicated by the broken lines are distributed standby floors as described above. Exchange.

  Also in this example, an elevator having the smallest non-stop floor in the zone is distributed and waited to each zone under the given dispersion waiting zone.

  According to the second embodiment, as in the first embodiment, the vehicle will be dispatched so that there is no non-stop floor around the waiting elevator. Distributed standby control that can shorten the waiting time can be realized.

  Here, supplementary explanations of the first and second embodiments are shown below.

  In the system according to the first embodiment, when the number of elevators with different floors increases, the number of times the standby elevator moves is increased. Thus, when the distribution target elevator is waiting in the zone, this problem can be overcome by avoiding the dispatch to the waiting floor. Furthermore, when the elevators are not used for a certain period of time, the standby positions of all the elevators can be reviewed to periodically optimize the standby positions of the elevators.

  FIG. 7 is an image diagram showing a distributed standby state when the present invention is applied to another form of group management elevator.

  FIG. 7 (A) shows an example in which six elevators are divided into three units, for service on lower floors 1 to 9 and for split express operation from the first floor to upper floors 10 to 17. is there. In the case of this example, the elevator for the upper layer service of the No. 4 Tang unit is illustrated as being in a distributed standby state according to the idea of the present invention as one zone on the first, tenth and eleventh floors.

  FIG. 7B is an example in which there are executive floors etc. on the fifth floor and are non-stop floors of two elevators, but in the same way as in Example 1 described above, Obviously, distributed standby control can be performed.
