  In an elevator that can switch between the normal operation mode and the dedicated operation mode, when the landing call is assigned during the normal operation and then the dedicated operation mode is switched, it is necessary to change the assignment destination of the landing call.

  The user who has been waiting in front of the elevator capable of switching the operation mode is not only confused when the arrival guidance is given to another elevator, but also needs to move to another elevator, which is inconvenient for the user. In addition, since the elevator that has been waiting until now moves to another elevator, there is a possibility that a user with a low moving speed such as an elderly person or a sick person will miss the elevator. Furthermore, in order to wait for the user whose movement speed is slow, the door open waiting time of the car becomes long, so that the operation efficiency is lowered.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a group management elevator system capable of improving convenience and operating efficiency.

  In order to solve the above problems, a group management elevator system according to the present invention is a group management elevator system for group management of a plurality of cars, and includes a landing call registration unit for registering a landing call and a landing call registration unit. An allocation determining unit for allocating a registered landing call to at least one of a plurality of cars, and the allocation determining unit includes a landing call between a predetermined car and another car among the plurality of cars. The assignment destination of the landing call is determined so that the assignment possibility of

  The predetermined car may be a car whose operation mode can be switched between the normal operation mode and the dedicated operation mode.

  The allocation decision unit does not include the landing call assignment target when the specified car is operating in the exclusive operation mode, and if the predetermined car is operating in the normal operation mode, the assignment frequency of the landing call is transferred to other cars. It is possible to determine the assignment destination of the landing call so as to be lower than the assignment frequency of the landing call.

  According to the present invention, it is possible to vary the assignability of a landing call between a predetermined car and another car, and it is possible to assign a landing call according to user convenience. Further, according to the present invention, in the group management elevator system having a predetermined car that can switch the operation mode between the normal operation mode and the dedicated operation mode, the change of the assignment destination of the landing call is reduced, and the convenience of the user is reduced. Can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, as will be described in detail below, when an elevator capable of switching operation modes is included, allocation of landing calls is controlled according to the operation mode.

A first embodiment will be described with reference to FIGS. In the present embodiment, description will be made centering on general landing calls, but other types of landing calls such as wheelchair landing calls can also be handled.
In the present embodiment, a case will be described in which a dedicated operation is performed for a specific user or a specific application, such as a so-called VIP mode, a mode allowing operation between specific floors, and a mode exclusively used by a stretcher. However, the present embodiment is not limited thereto, and can be applied to any elevator system including an elevator having an operation mode that does not respond to a general landing call.

  FIG. 1 shows the overall configuration of a group management elevator system 1. The group management elevator system 1 includes, for example, a plurality of elevators 10 and a group management control device 20.

  The elevator 10 includes, for example, a car 11, a hoisting machine 12, a main rope 13, a weight 14, a door 15, a landing call input device 16, and a destination floor operation unit 19 (see FIG. 2) in the car. The elevator control device 18 is provided.

  The user at the landing can call the elevator (car 11) by pressing the landing call input device 16 disposed near the elevator door 15 at the landing. Further, the user in the car can instruct landing on the target floor by operating the destination floor operation unit 19. The elevator control device 18 outputs a control signal based on the hall call and the car call appropriately assigned to any one of the cars 11 from the group management control apparatus 20.

  The hoisting machine 12 raises and lowers the car 11 through the main rope 13 by a control signal from the elevator control device 18. When the car 11 arrives at the target landing, the car door (not shown) is opened by the door driving device, and the landing door 15 is also opened following the movement of the car door. When a predetermined waiting time elapses or when the door is instructed from within the car, the car door is closed and the landing door 15 is also closed in conjunction with the movement.

  Of the plurality of elevators 10 shown in FIG. 1, the right elevator 10 (#n) is an elevator capable of switching the operation mode. The elevator 10 (#n) corresponds to a “predetermined car”. The elevator 10 (#n) capable of switching the operation mode has the same configuration as the other elevators 10 (# 1, # 2), and further includes an operation switch 17 for switching the operation mode in the car 11. In preparation. When a building administrator or the like operates the operation changeover switch 17, the normal operation mode is switched to the dedicated operation mode, and conversely, the dedicated operation mode is switched to the normal operation mode.

  The input device 30 is a device for registering various parameters related to the group management control of the elevator 10 in the group management control device 20.

  FIG. 2 shows a functional configuration of the group management control device 20. The group management control device 20 can be configured as a computer having a microprocessor, a memory, an input / output circuit, and the like, for example. Each function described later is realized by the microprocessor reading and executing a predetermined control program stored in the memory.

  The group management control device 20 includes, for example, a landing call registration device 21, an assignment determination unit 22, an elevator data management unit 23, and a parameter storage unit 24.

  The landing call registration device 21 is for registering landing calls generated by operating the landing call input devices 16. The allocation determining unit 22 is for allocating and dispatching at least one car 11 to the landing call registered in the landing call registration unit 21. The elevator data management unit 23 sends data on the operation status of each elevator 10 (destination floor, door open / closed state, number of passengers, operation mode, etc. instructed by the destination floor operation unit 19 in the car) from each elevator control device 18. Obtain and manage.

  In the present embodiment, the group management control device 20 outputs a command related to the operation control of each elevator 10 (such as a destination floor instruction, a service impossible floor instruction). Therefore, in the configuration of FIGS. 1 and 2, the hall call input device 16 is directly connected to the group management control device 20. However, instead of this, the landing call input device 16 may be connected to the group management control device 20 via the elevator control device 18. That is, the elevator control device 18 may be configured to acquire information related to each elevator 10 and transmit the information to the group management control device 20 via a wireless or wired communication line. Note that the operation changeover switch 17 may be directly connected to the group management control device 20 without using the elevator control device 18.

  The elevator control device 18 can receive an instruction from the group management control device 20 via a communication line, and can execute an operation according to the instruction. The elevator control device 18 controls, for example, door opening / closing, car departure, car landing, and the like. On the other hand, the group management control device 20 is in charge of designating the destination floor, forcibly opening and closing the door, and the like.

  The parameter storage unit 24 stores parameters used for group management control of the elevator 10 and the like. The parameter can be input from the external input device 30.

  FIG. 3 is a flowchart showing the overall processing executed by the group management control device 20. This process is executed when the group management control device 20 is powered on or restarted.

  First, the group management control device 20 executes an initial process for initializing parameters and the like (S10). Next, the group management control device 20 acquires and stores elevator data necessary for group management of the elevators from each elevator 10 (S20). Here, the elevator data includes the registration status of the car position, the driving direction, the destination floor call in the car, and the like.

  The group management control device 20 executes a landing call registration process for registering the landing call generated by the landing call input device 16 (S30). Subsequently, the group management control device 20 assigns the landing call registered in step S30 to at least one elevator (car) based on the elevator data acquired in step S20 (S40). When the group management control device 20 completes the assignment of the hall call, the group management control device 20 controls the elevator operation such as the traveling control and the door opening / closing control (S50), and returns to step S20. Steps S20 to S50 are repeatedly executed at a predetermined control cycle.

  FIG. 4 is a flowchart of the hall call assignment process (S40) in FIG. First, the group management control device 20 determines whether all the managed elevators 10 are in the normal operation mode (S41). When there is an elevator 10 operating in the dedicated operation mode (S41: NO), the group management control device 20 excludes the elevator 10 in the dedicated operation mode from the landing call assignment target (S42). Therefore, the hall call is not assigned to the elevator 10 in the exclusive operation mode.

  When only the elevator 10 in the normal operation mode (S41: YES), or when the elevator 10 in the exclusive operation mode is excluded from the assignment target of the landing call (S42), the group management control device 20 registers a new landing call. It is determined whether it has been done (S43). When the new hall call is not registered (S43: NO), the group management control device 20 determines whether it is necessary to reassign the hall call (S44). For example, when the arrival of the car at the floor where the landing call is generated is delayed for a predetermined time or more, it is determined that the reassignment of the landing call is necessary. If it is not necessary to reassign the landing call (S44: NO), this process ends. This is because there are no hall calls to be assigned.

  On the other hand, when a new landing call is registered (S43: YES), or when there is a landing call that needs to be reassigned (S44: YES), the group management control device 20 determines that “first evaluation value” An allocation evaluation value is calculated (S45).

  The group management control device 20 refers to, for example, elevator data, and uses a landing call, a car call (a call for designating a destination floor in the car), a car load (number of passengers), a current position of the car, and a moving direction of the car. Based on such information, an allocation evaluation value is calculated for each car. For example, the allocation evaluation value can be obtained from the viewpoint of improving the transportation efficiency of the entire elevator group so that the waiting time is shortened.

  Further, the group management control device 20 calculates a special evaluation value as a “second evaluation value” for a predetermined elevator (also called a predetermined car) that can be switched to the dedicated operation mode (S46). Here, it should be noted that the car can be switched to the dedicated operation mode, and the special evaluation value is calculated only for the car currently operating in the normal operation mode. Since the car already operating in the dedicated operation mode is excluded from the allocation target (S42), it is not necessary to calculate a special evaluation value.

  As will be described later, the group management control device 20 has a lower possibility of a landing call being assigned to a predetermined car than a possibility of being assigned to another car (a normal car that cannot be switched to the dedicated operation mode). Thus, a special evaluation value of a positive value is calculated. The calculated special evaluation value is added to the allocation evaluation value calculated for a predetermined car.

  As the special evaluation value, a preset fixed value may be used, or the special evaluation value may be appropriately calculated based on any parameter. For example, the administrator can set a special evaluation value in the group management control device 20 or set a parameter for calculating the special evaluation value via the external input device 30.

  The group management control device 20 assigns the new landing call registered in step S43 to the car having the smallest evaluation value (S47). In the case of a normal car, only the evaluation value for assignment is a judgment target. In the case of a predetermined car that can be switched to the dedicated operation mode, the total value of the evaluation value for allocation and the special evaluation value is a determination target. Therefore, the larger the special evaluation value, the lower the possibility that a landing call will be assigned to a predetermined car.

  In this embodiment, since the hall call is assigned based on so-called penalty control, the car having the lowest evaluation value is selected. On the other hand, in the case of so-called bonus control, the car having the highest evaluation value is selected. In the case of bonus control, the value of the special evaluation value can be set as a value close to 0 or a negative value.

  FIG. 5 shows the arrangement of the group management elevator. In FIG. 5, a total of six elevators 10 (# 1 to # 6) are arranged facing each other across a passage having an entrance at both ends. In the example of FIG. 5, the elevator 10 (# 6) of No. 6 can be switched to the dedicated operation mode.

  Here, consider a case where a new hall call is assigned to the elevator 10 (# 6) of the sixth car. If the elevator of Unit 6 is switched to the exclusive operation mode before the elevator of the Unit 6 (car) arrives at the landing, the landing call assigned to Unit 6 will be called the other elevators of Units 1 to 5 Need to be reassigned to

  If the hall call is assigned to the elevator 10 (# 1) of the first car, the user waiting in front of the elevator 10 (# 6) of the sixth car is as shown by a two-dot chain line in FIG. It is necessary to move a long distance toward the elevator of Unit 1. If the user who is forced to move is a slow walking user such as a sick person or an elderly person, there is a possibility that he / she may miss the elevator 10 (# 1) of the first unit.

  On the other hand, in this embodiment, a special evaluation value is added to the elevator 10 (# 6) that can be switched to the dedicated operation mode in addition to the normal evaluation value for assignment. For this reason, the evaluation value of the elevator 10 (# 6) that can be switched to the dedicated operation mode tends to be larger than that of the other normal elevators 10 (# 1 to # 5). Therefore, the possibility (assignment frequency) that a landing call is assigned to the elevator 10 (# 6) that can be switched to the dedicated operation mode is lower than that of other normal elevators 10 (# 1 to # 5).

  In this embodiment, the possibility of assigning hall calls to elevators that can be switched to the dedicated operation mode is reduced. For this reason, it is possible to suppress the occurrence of a situation in which a landing call assigned to an elevator that can be switched to the dedicated operation mode is reassigned to another elevator by switching the operation mode. Therefore, it is possible to reduce the occurrence of a change in the allocation of the landing call, to suppress the user from moving at the landing, and to improve the convenience for the user.

  A second embodiment will be described with reference to FIG. In the following embodiments, differences from the first embodiment will be mainly described. In this embodiment, a special evaluation value to be added to a predetermined car that can be switched to the dedicated operation mode is set according to the traffic volume of the group management elevator system.

  FIG. 6 is a graph for calculating the special evaluation value. The vertical axis shows the special evaluation value, and the horizontal axis shows the traffic volume (transportation volume). The traffic volume can be calculated, for example, by dividing a call (both landing call and car call) generated on a specific floor or floors by unit time.

  The special evaluation value is set so as to decrease from the initial value Pa1 to the lower limit value Pa2 (Pa1> Pa2) as the traffic volume increases. The special evaluation value decreases as the traffic volume increases.

  In the present embodiment configured as described above, as the traffic volume increases, the possibility that a landing call is assigned to a predetermined car that can be switched to the dedicated operation mode can be increased. Therefore, it is possible to improve the transportation efficiency of the entire group management elevator system by increasing the operation rate of the predetermined car. Further, in the present embodiment, when the traffic volume is small, the possibility that the landing call assigned to the predetermined car will be changed later is reduced as in the first embodiment, thereby improving the convenience of the user. It can be improved. As described above, in this embodiment, it is possible to realize both the improvement of the operation efficiency of the group-managed elevator and the improvement of the convenience for the user.

  A third embodiment will be described with reference to FIG. In this embodiment, the special evaluation value is adjusted according to the service time zone of the group management elevator system. FIG. 7 is a graph for calculating the special evaluation value. The vertical axis represents the special evaluation value, and the horizontal axis represents time. In the morning work time zone T0-T1 and the evening work time zone T4, the special evaluation value is set to the lower limit Pa4. In daytime T2-T3 when the traffic volume is relatively small, the special evaluation value is set to the upper limit value Pa3.

  Therefore, in this embodiment, the user can be transported using a predetermined car that can be switched to the dedicated operation mode in the morning and evening congestion. Thereby, congestion can be eased and the operation efficiency of the group-managed elevator can be improved. Furthermore, in the present embodiment, it is possible to improve the convenience of the user by suppressing the occurrence of a situation in which a hall call assigned to a predetermined car is reassigned to another car during the daytime when traffic is stable.

  Furthermore, in the present embodiment, the special evaluation value is set so as to gradually increase with the passage of time in the time period T1-T2 from the working hours when traffic is heavy to the daytime when the traffic is stable. . In the time zone T3-T4 from the daytime time zone to the office hours when there is a lot of traffic, the special evaluation value is set so as to gradually decrease as time elapses.

  Therefore, in the present embodiment, it is possible to adjust the use frequency of the predetermined car (assignment frequency of the landing call) according to the use situation of the elevator. As a result, the same effects as those of the second embodiment can be obtained. The graph shown in FIG. 7 may be prepared according to the day of the week or the season, such as for weekdays, holidays, and long holidays such as summer holidays.

  A fourth embodiment will be described with reference to FIGS. In this embodiment, in order to prevent the user from staying near the predetermined car (# 4), it is easy to assign a landing call to another car far from the predetermined car (# 4).

  FIG. 8 shows the arrangement of the group management elevator according to this embodiment. In the present embodiment, a total of six elevators 10 are arranged opposite to each other at the landing where the dead end is reached. The elevator 10 (# 4) located near the entrance of the landing is assumed to be a predetermined car that can be switched to the dedicated operation mode.

  FIG. 9 is a graph for calculating the evaluation value for assignment. The vertical axis represents the evaluation value for assignment, and the horizontal axis represents the distance for each predetermined car. For the elevator closest to the predetermined car, the evaluation value of the upper limit value Pb1 is given. An evaluation value of the lower limit value Pb2 is given to the elevator farthest from the predetermined car. The graph is set such that the farther the predetermined car distance is, the smaller the evaluation value for assignment becomes. To be exact, the basic value of the evaluation value for assignment is calculated by, for example, the current position of the car, the number of assigned calls, the moving direction, the load, etc., and the basic value is calculated from the graph of FIG. The assigned evaluation value Pb is added to obtain the assigned evaluation value in this embodiment.

  In this embodiment, the farther away from a predetermined car, the higher the possibility that a landing call will be assigned, so the number of users waiting in front of the predetermined car can be reduced. Therefore, when a predetermined car needs to be switched to the dedicated operation mode, the predetermined car can be used quickly for a dedicated purpose. For example, when a sick person is transported to an operating room on a stretcher or the like, the number of people waiting in front of a predetermined car is small, so it is possible to quickly put a stretcher in a predetermined car and carry the sick person to the operating room. it can.

  In particular, when a predetermined car that can be switched to the dedicated operation mode is provided in the vicinity of the entrance / exit of the platform, if a large number of users stay around the entrance / exit, a smooth movement flow line cannot be secured, and group management is performed. The operating efficiency of the elevator is reduced. On the other hand, in the present embodiment, since it is easy to assign a landing call to a car away from a predetermined car, it is possible to secure a smooth movement flow line and improve operating efficiency. Furthermore, in the present embodiment, when the operation mode of a predetermined car is switched to the dedicated operation mode, it can be used quickly. This embodiment can be applied to any of the first, second, and third embodiments.

  In addition, this invention is not limited to the Example mentioned above. A person skilled in the art can make various additions and changes within the scope of the present invention.
