Definitions

  • the present invention relates to an elevator system which performs group supervisory control of a plurality of elevators and can switch a subset of the elevators to exclusive operations.
  • a plurality of elevators are installed within the same building and group supervisory control of the plurality of elevators is performed to improve the overall efficiency of operation.
  • Some of such elevators are configured in such a manner that a subset of the elevators under group supervisory control are capable of being switched to exclusive operations. Examples of exclusive operations include a VIP (very important person) operation dedicated to VIPs, and a baggage operation for conveying large baggage and the like.
  • VIP very important person
  • Patent Document 1 Japanese Patent Laid-Open No. 2004-18229
  • JP H06 199481 A teaches an elevator system having a first and a second elevator.
  • the system further includes a VIP call button. If the VIP call button is pushed, only the first elevator responds to the VIP call. Further, if the VIP call button is pushed, an estimated time of arrival at the VIP floor is determined based on the thus registered car calls. On the basis of the thus estimated time, then one of following actions is taken before the first elevator arrives at the VIP floor: (a) The first elevator responds to all of the thus registered car calls, (b) The first elevator responds to some of the thus registered car calls, (c) The first elevator responds to none of the thus registered car calls and goes directly to the VIP floor.
  • the elevator system described in Patent Document 1 had the problem that a delay occurs in a switchover to an exclusive operation. That is, even when a switchover to an exclusive operation for VIPs and other persons has been performed, it is after all users who have registered their destination calls are conveyed to designated floors that the exclusive operation is actually started. Particularly, in buildings where the number of elevator users is large and in prescribed time zones, a long time passes before a switchover to an exclusive operation, with the result that VIPs and other persons had to wait for a long time.
  • the present invention has been made to solve problems as described above and the object of the invention is to ensure that in an elevator system which enables a subset of a plurality of elevators under group supervisory control to be switched to exclusive operations, a decrease in the operation efficiency of the whole system can be prevented and switchovers to exclusive operations can be performed quickly.
  • An elevator system of the present invention is an elevator system that performs group supervisory control of a plurality of elevators, as defined by claim 1.
  • an elevator system which enables a subset of a plurality of elevators under group supervisory control to be switched to exclusive operations, it becomes possible to prevent a decrease in the operation efficiency of the whole system and to perform switchovers to exclusive operations quickly.
  • FIG. 1 is a block diagram showing an elevator system in a first embodiment according to the present invention.
  • a plurality of elevators installed within the same building are brought under group supervisory control and furthermore a subset of the elevators (one or more elevators) can be switched to exclusive operations, such as a VIP operation and a baggage operation.
  • reference numeral 1 denotes a call registration device for registering destination floors of the elevator.
  • this call registration device 1 sends a destination call registration request for registering a destination call to a group supervisory controller 2.
  • the call registration device 1 is provided with assignment car information means 3 which informs users nearby of a car assigned to the destination call registration request (hereinafter, referred to also as an "assignment car").
  • the above-described call registration device 1 is installed in each hall of the elevator, for example, and is provided with input buttons with which users register their destination floors before they get in the car, and a display or a speaker for informing elevator users nearby of an assignment car.
  • this configuration shows only one example and the call registration device 1 may be otherwise configured.
  • the call registration device 1 may be a mobile terminal carried by an elevator user, which permits radio communication with the group supervisory controller 2.
  • a cellular phone, a PHS (Personal Handyphone System), a PDA (Personal Didital Assistance), a notebook-size personal computer and the like can be used as the above-described mobile terminal.
  • the call registration device 1 may be such that the device has a function of personal ID collating function and personal ID data as a function for registering destination floors and that when a user collates a personal ID, the device refers to the personal ID data and automatically discriminates a destination floor.
  • a destination call registration request corresponding to the destination floor stored in the personal ID data is automatically sent to the group supervisory controller 2.
  • the collation of a personal ID by a user is performed on the basis of, for example, a key, a card an IC tag and the like in which a personal ID is recorded, and biological information, such as a fingerprint, a vein, a voice print and an iris.
  • the group supervisory controller 2 is a device for group supervisory control of a plurality of elevators installed in the same building.
  • the group supervisory controller 2 is provided with, for example, assignment car determination means 4 and exclusive operation control means 5.
  • the assignment car determination means 4 has a function of assigning a car on the basis of the operation condition of each elevator and the like to a received destination call registration request when the group supervisory controller 2 has received the destination call registration request. And after performing the assignment of a car to the destination call registration request, the assignment car determination means 4 sends destination call assignment instructions to an each-elevator supervisory controller 6 and sends assignment car information to the call registration device 1.
  • the each-elevator supervisory controller 6 performs the operation control of each elevator.
  • the each-elevator supervisory controller 6 is provided with car control means 7 which performs the operation control of the car of each elevator. And upon receipt of the destination call assignment instructions from the assignment car determination means 4, the each-elevator supervisory controller 6 appropriately controls the operation of the car on the basis of the assigned destination call.
  • the assignment car information means 3 On the basis of the assignment car information received from the assignment car determination means 4, the assignment car information means 3 performs lamp display and announcement, thereby informing users nearby of information on the assignment car.
  • an exclusive operation switchover device 8 is intended for switching a subset of a plurality of elevators under group supervisory control to exclusive operations.
  • this exclusive operation switchover device 8 sends an exclusive operation switchover request for switching the above-described subset of the elevators to the group supervisory controller 2.
  • the exclusive operation control means 5 has a function of shifting the above-described subset of the elevators to exclusive operations on the basis of the exclusive operation switchover request received from the exclusive operation switchover device 8. Concretely, this exclusive operation control means 5 is provided with service time computation means 9 and threshold value storage means 10.
  • the service time computation means 9 has a function of computing time necessary for performing a service (hereinafter referred to as "service time") to a destination call which has already been registered by the call registration device 1. For example, upon receiving an exclusive operation switchover request, this service time computation means 9 computes service time for the destination calls which have already been registered before the receipt of the exclusive operation switchover request regarding the subset of the elevators to be shifted to exclusive operations.
  • a prescribed threshold value is stored in the threshold value storage means 10.
  • the exclusive operation control means 5 performs services to the destination calls which have already been registered in a range not exceeding the above-described prescribed threshold value and thereafter shifts the subset of the elevators to exclusive operations. For example, when services to all destination calls that have already been registered are completed in the range of the threshold value stored in the threshold value storage means 10, the exclusive operation control means 5 performs all of the services and thereafter makes a shift to exclusive operations.
  • the exclusive operation control means 5 When the services to all of the destination calls that have already been registered are not completed in a range not exceeding the above-described prescribed threshold value, the exclusive operation control means 5 performs only services to some of the destination calls and makes a shift to exclusive operations without performing services to the remaining destination calls.
  • the call registration device 1, group supervisory controller 2 and each-elevator supervisory controller 6 are each connected by a network and are configured to be able to mutually perform information communication.
  • Figure 2 is a flowchart showing the operation of the elevator system in a first embodiment according to the present invention.
  • a destination call registration request is sent from the call registration device 1 to the group supervisory controller 2 (S1).
  • the group supervisory controller 2 determines an assignment car for the received destination call registration request by using the assignment car determination means 4. After the determination of the assignment car, the group supervisory controller 2 sends instructions for the assignment to the destination call to the each-elevator supervisory controller 6 and sends assignment car information to the call registration device 1 (S3).
  • the call registration device 1 Upon receipt of the assignment car information (S4), the call registration device 1 informs users nearby of information on the assignment car with the assignment car information means 3 (S5).
  • the each-elevator supervisory controller 6 which has received the instructions for the assignment to the destination call controls the car on the basis of the received destination call and conveys the user to the destination floor.
  • each-elevator supervisory controller 6 sequentially performs services to the registered destination calls on the basis of a prescribed order and the like and conveys users to the destination floors.
  • an exclusive operation switchover request is sent from the exclusive operation switchover device 8 regardless of the operation condition of the elevator (S6).
  • the group supervisory controller 2 selects an elevator for which a switchover to an exclusive operation is performed on the basis of prescribed settings, conditions and the like.
  • service time for destination calls which have already been registered at the time of receipt of the exclusive operation switchover request is computed by using the service time computation means 9 regarding the above-described selected elevator (hereinafter referred to as the "selected elevator")(S8).
  • the exclusive operation control means 5 compares the service time computed at S8 with the prescribed threshold value stored in the threshold value storage means 10, and cancels destination calls for which the service completion time exceeds the threshold value, among the destination calls assigned to the car of the selected elevator (S9). Incidentally, at S9, when a car has not yet arrived at the departure floor for the destination calls to be cancelled, a change of the assignment of destination calls may be made.
  • the exclusive operation control means 5 makes a judgment as to whether or not there are destination calls for which the service completion time does not exceed the threshold value, among the destination calls assigned to the car of the selected elevator (S10).
  • the exclusive operation switchover request is put on hold until the service for the destination call is completed (S11) and after the completion of the above-described service, instructions for exclusive operation execution are sent to the each-elevator supervisory controller 6 of the selected elevator (S12).
  • each-elevator supervisory controller 6 starts an exclusive operation (S14).
  • the group supervisory controller 2 upon receipt of an exclusive operation switchover request, performs services to destination calls which have already been registered in a range not exceeding a prescribed threshold value regarding an elevator which is to be shifted to an exclusive operation and does not perform services to other destination calls. Therefore, it is possible to adjust the time until the start of an exclusive operation by the above-described threshold value, and it is possible to positively prevent situations in which VIPs and other persons wait for a long time. Furthermore, because even upon receipt of an exclusive operation switchover request, services to destination calls which have already been registered are performed in a range not exceeding a prescribed threshold value regarding an elevator which is to be shifted to an exclusive operation, an extreme decrease in the operation efficiency of the whole system does not occur and it is possible to maintain efficient operations.
  • services for destination calls may be performed in the order of earlier to later ones, or it may be ensured that services for destination calls can be performed as many as possible.
  • Services to be performed may be determined by giving some order of priority to destination calls, and services for car calls may be preferentially performed. At this time, among destination calls in which a threshold value is exceeded, for car calls which have already been registered, canceling is performed and for hall calls which have already been registered, the assignment to other elevators is changed or canceling is performed.
  • services to be performed before switchovers to exclusive operations are judged on the basis of the time necessary for performing services for destination calls which have already been registered. However, a judgment may be made by considering also the movement time until arrival at a floor at which an exclusive operation is started in addition to the above-described time.
  • the exclusive operation control means 5 performs services for some of the destination calls which have already been registered in a range not exceeding the prescribed threshold value and the movement to a floor at which an exclusive operation is started, and thereafter switches a subset of the elevators to exclusive operations. According to such a configuration, it becomes possible to positively prevent the start of an exclusive operation from delaying.
  • the exclusive operation switchover device 8 is configured to send a switchover request which differs from one kind of exclusive operation to another. And a threshold value is individually set for each kind of switchover request and is caused to be stored in the threshold value storage means 10.
  • the switchover time to an exclusive operation may be adjusted for each user of exclusive operation, i.e., for each class or each priority of a user.
  • the exclusive operation switchover device 8 is configured to send a switchover request which differs from one user of exclusive operation to another.
  • a threshold value is individually set for each switchover request and is caused to be stored in the threshold value storage means 10.
  • the switchover time to an exclusive operation may be capable of being appropriately adjusted according to the degree of crowdedness of an elevator (for example, the number of passengers getting in and off and the number of calls).
  • judgment means which judges the degree of crowdedness of elevators in group supervisory control becomes further necessary.
  • the above-described prescribed threshold value is individually set on the basis of the degree of crowdedness judged by this judgment means. If such a configuration is adopted, it becomes possible to positively prevent a decrease in the operation efficiency of the whole system.
  • a threshold value may also be set by a plurality of combinations of the above-described elements (kinds of exclusive operations, users of exclusive operation, the degree of crowdedness of elevators). According to such a configuration, it is possible to flexibly adapt to various kinds of elevators.
  • the elevator system related to the present invention can be applied to an elevator system which performs group supervisory control of a plurality of elevators and can switch a subset of the elevators to exclusive operations. When there are many elevator users, this elevator system provides especially effective means.
