An apparatus 15 and a group management apparatus 3 for determining a car that can get in on a destination floor call acquired by the destination floor registration system 2 are provided. The group management device 3 assigns, to one of the cars, a destination floor call that occurred between the arrival of a car and the elapse of the registration grace time. Then, the group management device 3 outputs a predetermined command relating to the predetermined car based on the predetermined door opening time limit and the destination floor call set for the predetermined car to which the destination floor call has been allocated. As a result, in the present embodiment, only the destination floor call within the registration grace time is permitted, so that departure of the car can be performed without delay, and both the operation efficiency as a whole and the improvement of the service quality can be achieved. it can.

  According to the present embodiment, only the destination floor call generated within the registration grace period is permitted, and the door open time period is extended in consideration of the walking time from the destination floor registration device to the elevator of the landing. Therefore, according to the present embodiment, a new destination floor call generated within the registration grace period can be allocated to the car (car) assigned to the destination floor call, so that the number of passengers can be increased. As well as being able to reduce the delay in departure.

  The first embodiment will be described with reference to FIGS. FIG. 1 shows the entire configuration of an elevator group management system according to the present embodiment. The elevator group management system comprises a elevator control device 15 for controlling a plurality of elevators 1 (A) to 1 (N) and each elevator 1 (A) to 1 (N), a destination floor registration system 2, and a group And a management device 3. Hereinafter, the elevator No. will be abbreviated as “No. When the units 1 (A) to 1 (N) are not particularly distinguished, they are called unit 1.

  The unit 1 moves the floor between the plurality of floors to transport the user. The floor may be abbreviated as floor below. Unit 1 includes, for example, a car 10, a hoisting machine 12 for raising and lowering the car 10 using the main ropes 13, and a counterweight 14 for raising and lowering in the opposite direction to the car 10 according to the movement of the main ropes 13. And

  Further, a door 11 is provided in the car 10 so as to be openable and closable. When the car 10 arrives at the landing 4, the door 11 is opened, and the landing door 41 (see FIG. 5) is also opened by the opening operation. After the car 10 arrives at the landing 4, the car 10 stands by with the door 11 open for a predetermined time. It is called a door open standby that the car 10 stands by at the landing 4 with the door 11 open. When the user (passenger) on board operates the door closing button (not shown) of the operating device in the car 10 or the maximum door open time limit has elapsed, the car 10 closes the door 11. The landing door 41 is also closed by the closing operation. When the car 10 is closed, it leaves the hall 4 and moves to the floor designated by the destination floor call. The elevator control unit 15 takes charge of opening / closing and moving of the car 10. The unit control unit 15 controls the door open state of the car 10 in accordance with the command from the group management unit 1.

  The destination floor registration system 2 is a system for inputting and registering the destination floor, which is the purpose of the user, into the group management device 3 before the user arrives at the landing 4. The destination floor registration system 2 can include, for example, a destination floor registration device 20, a destination floor reading unit 21, an input / output control system 22, and a tag or a terminal 23.

  The landing destination floor registration device 20 is, for example, a device installed in the vicinity of the hallway of the building, in the vicinity of the entrance of the building, in the vicinity of the landing 4 or the like. The destination floor registration device 20 may be abbreviated below. As shown in FIG. 5, the destination floor registration device 20 includes, for example, an input device 200, a display device 201, a special button 202, and the like. The input device 200 is a device for the user to input a numerical value indicating a destination floor. The input device 200 includes, for example, a ten key. The display device 201 is a device that displays a value input from the input device 200 or displays a number assigned to the input destination floor. The display device 201 includes, for example, a liquid crystal display, an organic light-emitting diode (OLED) display, and the like. The special button 202 is, for example, a button for inputting special circumstances such as a small child, a wheelchair user, a sick person or a heavy luggage. The user can also input the expected number of passengers and the like from the input device 200.

  The configurations of the input device 200, the display device 201, and the special button 202 are not limited to the above-described example. For example, the display device 201, the input device 200, and the special button 202 may be integrally configured as a touch panel. A voice input device may be used as the input device 200.

  Return to FIG. The destination floor reading unit 21 communicates with the destination floor registration device 20, receives information (destination floor, number of people) input to the destination floor registration device 20, and receives information from the group management device 3 as the destination floor registration device 20. Send to The destination floor reading unit 21 includes, for example, an information acquisition unit 210 and a notification unit 211. The information acquisition unit 210 acquires the destination floor input to the destination floor registration device 20 as described above. The notification unit 211 transmits, to the destination floor registration device 20, information on the machine 1 to which the destination floor call has been assigned by the group management device 3.

  The input / output control system 22 is located between the destination floor reading unit 21 and the group management device 3 and takes charge of information input / output between the destination floor reading unit 21 and the group management device 3. The input / output control system 22 may be considered as a subsystem of the group management apparatus 3 or may be considered as a system independent of any of the group management apparatus 3 and the destination floor registration system 2.

  Instead of the destination floor registration device 20 or together with the destination floor registration device 20, a tag or a terminal 23 can be used. The destination floor can also be input using a portable terminal device such as a so-called IC card, a mobile phone, a portable information terminal, a tablet PC or the like.

  For example, in the case of an IC tag or IC card type employee ID card, the destination floor reading unit 21 may be provided at the entrance gate of the building, and the destination floor may be automatically set from the employee number read from the employee ID card. For example, the group management device 3 holds a table for managing a set of an employee number and a floor, and determines the floor associated with the employee number read from the employee ID card as the destination floor. Alternatively, the user can input the destination floor via a mobile phone or a portable information terminal.

  The group management device 3 is a computer device that manages each car 1 as a group. The group management device 3 includes, for example, hardware such as a microprocessor, a memory, an auxiliary storage device, and an input / output circuit, and software such as an operating system and a control program.

  The following describes the functions implemented as a result of the cooperation between the above hardware and software. The group management apparatus 3 includes, for example, a learning system 30, an intelligence system 31, and an operation management control unit 32, in addition to the normal function as the elevator group management apparatus.

  The group management device 3 monitors and stores the daily operation status of each unit 1 as one of the normal functions. For example, the learning system 30 analyzes and learns the current operation situation data to determine which of the known operation patterns the current operation pattern corresponds to. The intelligence system 31 detects the unknown operation pattern by analyzing the operation status data. For example, when tenants in a building are replaced, the time and frequency of using an elevator change, and a new operation pattern is generated. When the intelligence system 31 detects a new operation pattern, it informs the learning system 30.

  The operation management control unit 32 assigns the unit 1 to the destination floor call, and manages the door open period of each unit 1 and the like. The operation management control unit 32 includes, for example, a time setting unit P1, a destination floor call assignment processing unit P2, and a command unit P3.

  The time setting unit P1 includes a registration grace time setting unit 320 and a walking time setting unit 321. The registration grace time setting unit 320 is a function of setting the registration grace time for each floor or every generation period. Here, the registration grace time is the time when the destination floor call can be registered. The registration grace time starts when the machine 1 arrives at the floor where the destination floor call has occurred, and ends when the registration grace time expires. As will be described later with reference to FIG. 6, assuming that the machine 1A arrives at the floor where the destination floor call has occurred at a certain time T0, the registration allowance time t1 starts from that time T0. At the time T1 (= T0 + t1) at which the registration grace time t1 expires, the destination floor call is not assigned to the machine whose registration grace time t1 has expired.

  In other words, registration postponement time setting unit 320 sets a grace period to determine up to which point in time the registration of the destination floor call is permitted for the candidate machines that can be assigned without being excluded by assignable machine selection unit 322. Do.

  Return to FIG. The walking time setting unit 321 sets a walking time. The walking time as an example of the “time required for moving” is the time required for the user to move from the installation location of the destination floor registration device 20 to the landing door 41 of the predetermined car 1. The walking time is set in accordance with the distance to each row first floor registration device 20 and the landing door 41 of each car 1.

  For example, if the standard walking speed of the user is set in advance, the walking time is calculated by dividing the distance between the destination floor registration device 20 and the landing door 41 of each car 1 by the standard walking speed (standard moving speed) it can. The walking time setting unit 321 holds a speed slower than the standard walking speed in preparation for the case where the walking speed is slower than the standard walking speed, as in the case of small children or carrying heavy luggage. It can also be done. The walking time setting unit 321 sets the walking time when the installation place of the destination floor registration device 20 is changed or when the destination floor registration device 20 is newly installed.

  The destination floor call assignment processing unit P2 is a function of assigning a destination floor call to any one of the number 1 machines. The destination floor call assignment processing unit P2 includes, for example, an allocatable car selection unit 322 and a destination floor registration processing unit 323.

The assignable car selection unit 322 selects at least one car from among the cars 1 to which the destination floor call can be allocated. The allocatable car selection unit 322 extracts allocatable car candidates based on at least one exclusion condition set in advance, as described later with reference to FIG. Specifically, for each of a plurality of exclusion conditions set in advance, a car that is unsuitable for the assignment of the destination floor call is determined and removed from the assignable car candidates. With exclusion conditions, as described later in FIG. 2, for example, it is under preparation for departure after the registration postponement time (S3) or is predicted to be full (S5), or the user is not in time for the landing Or (S7).
The machine 1 corresponding to any of the exclusion conditions is excluded from the machine candidates to which the destination floor call can be assigned. Only machines that have cleared all the exclusion conditions are selected as possible car assignable destination floor calls.

  The destination floor registration processing unit 323 selects one of the assignable machine candidates 1 from the assignable machine candidates, and assigns and registers the destination floor call to the selected machine 1. For example, it is determined in consideration of a car call or a platform call assigned to the machine 1 and the number of passengers (or total load) of the machine 1 whether the machine 1 is capable of the optimal operation.

  The command unit P3 is a function of issuing a predetermined command to the number 1 to which the destination floor call is assigned. The command unit P3 includes, for example, a time limit management processing unit 324 and a door open command processing unit 325.

  The time limit management processing unit 324 manages elements relating to time management such as registration delay time, walking time, door open time limit and the like. The door-opening command processing unit 325 sends, to the vehicle-control device 15, a command for applying the door-opening time limit used for the machine 1 to which the destination floor call is assigned to the machine 1.

  In addition, as described later with reference to FIG. 2, the command unit P3 transmits information for specifying the machine 1 to which the destination floor call has been assigned to the destination floor registration device 20 for guidance (S10), or in the vicinity of the landing door 41. The planned stoppage floor of the elevator 1 may be displayed (S11).

  The functional configuration of the group management device 3 is not limited to the example shown in FIG. A certain function and another function may be integrated into one function, a certain function may be divided into a plurality of functions, or a function not shown in FIG. 1 may be added.

  The division of roles of the functions 30, 31, 32 is not limited to the above-described example. In short, it is possible to set the registration grace time for each floor or every car (for each platform door), and the destination floor that occurred between the arrival of the aircraft 1 at the hall 4 and the expiration of the registration grace time. It is sufficient that the call can be assigned to any one of the machines 1.

  FIG. 2 is a flowchart showing the processing operation in the operation management control unit 32 of the group management device 3.

  Similar to the group management apparatus of the normal configuration, the group management apparatus 3 of this embodiment receives the car data from each car control apparatus 1 (A) to 1 (N) (S1). The machine data is data relating to the state or operation of the machine 1, and includes, for example, movement direction, total load, car call status, door open / close state, and the like.

  The group management device 3 determines the state of each car based on the data of each car received in step S1, and then determines, through the input / output control system 22, whether the destination floor call by the hall destination floor registration device 20 has been registered. To do (S2). If the destination floor call has not been registered (S2: NO), there is no need to assign the machine 1, so the process moves to step S10.

  When the destination floor call is registered (S2: YES), the group management device 3 allocates one car 1 to the destination floor call as described below (S3 to S9).

  The allocatable machine selection unit 322 excludes those that do not satisfy the conditions for the allocation machine candidate (S3 to S8). In the present embodiment, three exclusion conditions are provided. Not limited to this, four or more exclusion conditions may be set.

  The allocatable machine selection unit 322 determines whether there is a machine 1 that is in preparation for departure by expiring the registration grace time t1 set by the registration grace time setting unit 320, for all the machines 1 (see FIG. S3). In this embodiment, the destination floor call is not assigned to the machine 1 which has passed the registration grace time. This is to prevent departure delays.

  If the allocatable machine selection unit 322 determines that the machine 1 in preparation for departure is present after expiration of the registration grace period (S3: YES), the machine 1 is excluded from the candidate machines of the destination floor call (S4). On the other hand, if the allocatable machine selection unit 322 determines that the machine 1 corresponding to the exclusion condition in step 3 does not exist (S3: NO), the process skips step 4 and proceeds to step S5.

  The allocatable machine selecting unit 322 determines whether there is a car whose fullness is predicted to be for all cars 1 that have not been excluded from the allocated car candidates (S5). The full capacity is a state where the maximum capacity of the car 10 is reached. The group management device 3 can estimate the number of users (number of passengers) in the car based on the load signal detected by the load sensor. Alternatively, the group management device 3 can also detect a user getting on and off the car 10 based on a detection signal of an image sensor installed at the landing 4.

  When the user registers the destination floor in the destination floor registration device 20, it is possible to count one input of one person as one person and detect the expected number of passengers. It may be possible to input the number of users. The group management device 3 can predict whether the car 10 of the car 1 will be full based on the average weight of the user from the detected number of people expected to board.

  When it is determined that the car 10 is fully occupied when the assignable car selection unit 322 places one or more users who registered destination floor calls on board (S5: YES), the possibility of the car being full. Machine number 1 is excluded from the allocation machine candidate (S6). On the other hand, when the allocatable machine selection unit 322 is not predicted to be full (S5: NO), the process skips step S6 and proceeds to step S7.

  The allocatable machine selection unit 322 is a walk required for a user who has registered a destination floor call in the destination floor registration device 20 to reach the landing door 41 for all the machines 1 that have not been excluded from the allocation machine candidates. The total value of time t5 and the estimated arrival time required for the unit 1 to be judged to arrive at the registered floor of the destination floor call is compared with the preset maximum door opening time limit t4 (walking time> (Estimated arrival time + maximum opening time limit)). The allocatable car selection unit 322 can use the walking time set by the walking time setting unit 321 in the determination of step S7.

  If the allocatable machine selection unit 322 determines that the walking time is larger than the sum of the estimated arrival time of the machine 1 and the maximum door opening time limit (S7: YES), the machine is excluded from the candidate machines for allocation (S8). ). In this case, it takes a long time (> arrival time + maximum opening time limit) until the user who registered the destination floor call reaches the landing door 41, and the departure is delayed, and other users who have already boarded in The quality of service for On the other hand, if the allocatable machine selection unit 322 determines that the walking time of the user who has registered the destination floor call is equal to or less than the sum of the estimated arrival time of the car 1 and the maximum door open time limit (S7: NO), The process skips step S8 and proceeds to step S9.

  When the destination floor registration processing unit 323 receives the information on the candidate machines extracted by the allocatable machine selection unit 322, the destination floor registration processor 323 selects one of the candidate machines that is most suitable for allocating the destination floor call (S9). . The destination floor registration processing unit 323 selects one car, for example, using the machine with the fastest arrival time to the floor where the destination call has occurred, the car with the smallest total load, and the like as a selection criterion.

  Furthermore, the destination floor registration processing unit 323 causes the time limit management processing unit 324 to provide the door opening command processing unit 325 with the door opening time limit information used to determine the assigned car in step S7. The door open command processing unit 325 gives a command to the machine control device 1 of the machine to which the destination floor call is assigned, so as to execute the door open time period corresponding to the exclusion condition of step S7.

  Thereafter, the group management device 3 executes the machine guidance processing (S10) and the scheduled stop floor display processing (S11), and ends this processing. In the machine guidance process of step S10, the information specifying the car to which the destination floor call has been assigned is notified from the input / output control system 22 to the user via the notification unit 211 and the destination floor registration device 20. The notification unit 211 may notify the user of the information (machine number) of the machine to which the destination floor call is assigned, through a display such as a mobile phone or a portable information terminal held by the user or an audio output device. The user moves toward the landing door 41 of the guided vehicle.

  In the scheduled stop floor 4 of step S11, the scheduled stop floor of each car 1 can be displayed. For example, the group management device 3 can display the planned stoppage floor of each car 1 using a display installed at the landing 4 or a display light installed near the landing door 41. The user who has arrived at the landing 4 confirms the stop floor of the elevator 1 notified at step S10, and stands by there.

  FIG. 3 shows a configuration example of a registration grace time setting table T1 used by the registration grace time setting unit 320. The registration grace time setting table T1 sets and manages a registration grace time t1 for permitting assignment of a destination floor call for each floor (or for each car).

  The registration grace time setting table T1 associates and manages, for example, the floor space column C10, the number of used people column C11, and the grace time column C12. In the present embodiment, the value t1 of the grace period is set in the grace period column C12 according to the number of users on each floor. In the present embodiment, for example, the threshold number of users is set to 50, and a value obtained by dividing the value of the number of users column C11 by the number threshold of users is calculated as the suspension time t1 (suspension time t1 = number of users / number of users) Threshold).

  The number of users can be set in the number of users column C11 based on the learning result of the daily operation status by the learning system 30. For example, the learning system 30 calculates and outputs the number of users on each floor every predetermined time, such as every five minutes, every ten minutes, or every thirty minutes. The number of users on each floor is the number of users on the departure floor. The registration grace time setting table T1 can be updated according to the time zone. A table T1 shown in FIG. 3 indicates, for example, a grace period at work.

  At a certain point shown in FIG. 3 (for example, work time in the morning), the number of users on the first floor is the largest at "250" and the quotient divided by the threshold "50" is "5". Therefore, the grace period on the first floor is set to "5 seconds".

  On the other hand, the number of users on the second floor is relatively small, "20", and the quotient divided by the threshold "50" is "0". Therefore, the grace period of the second floor is set to "0 seconds". The number of users on the fourth floor is "30", and the quotient divided by the threshold "50" is "0". Therefore, the grace period of the fourth floor is also set to "0 seconds". Since the number of users on the third floor is "60", the quotient divided by the threshold "50" is "1". Therefore, the grace period of the third floor is set to "one second". Since the number of users on the fifth floor is "50", the quotient divided by the threshold "50" is "1". Therefore, the grace period of the fifth floor is also set to "one second".

  The grace time t1 set in the grace time column C12 starts from the time when the aircraft 1 arrives at the landing 4 as a starting point. For example, on the first floor, counting starts from the time when the machine arrives at the landing, and the grace period expires in 5 seconds. If the user registers a destination floor call before the expiration of the grace period t1, the user can get on the platform because the destination floor call can be assigned to the corresponding platform. On the other hand, for the destination floor call registered by the user after expiration of the grace period t1, the destination floor call is not assigned to the corresponding machine, and therefore the user can not get on the machine.

  When the grace time t1 is set to a large value, the time from the floor to the departure of the machine 1 becomes long. Therefore, in the present embodiment, on floors having a small traffic volume, the value of the grace period t1 is set small to make it easy to respond to calls on other floors. On the other hand, on a floor with a large traffic volume, setting the value of the grace time t1 to be relatively large makes it easy for passengers to get into the car 10 and to increase the riding rate. Thereby, in the present embodiment, on the floor with few users, the waiting time in the door open standby state is shortened to accelerate the departure of the machine 1, and in the floor with many users, the waiting time in the door open standby state is lengthened to get on The rate can be improved. Thus, in the present embodiment, it is possible to improve both the service quality and the transportation efficiency (operation efficiency).

  The user number threshold may be a fixed value, or may be changed according to the operation situation. The user number threshold may be calculated from parameters such as the structure of the building, the number of people in the building, the number of elevators installed, and the maximum number of passengers (maximum load) of the car, or a building described in Japanese Industrial Standards. It may be calculated from the traffic calculation method used for the installation plan.

  FIG. 3 shows the grace time for each floor at a certain time. The registration delay time setting table T1 may be updated each time the learning result of the operation status is updated, or may be updated at a predetermined time. The grace period may be adjusted in consideration of the day of the week and public holidays. Furthermore, the manager of the elevator group management system may adjust the grace time manually.

  FIG. 4 shows an example of a table T2 for managing the door open time limit. The door open time limit management table T2 manages, for example, the floor column C20, the normal door open time limit column C21, the door open time column C22 when the walking time is considered, and the maximum door open time limit column C23 in association with each other. In FIG. 4, the door open time limit of the first floor unit 1 is shown, and the other floor and the other unit open time limits are not shown. In addition, since it is only the door opening time column C22 at the time of consideration of the walking time that the case different depending on each unit surely occurs, the normal door opening period column C21 and the maximum door opening period column C23 for each floor of each unit If the same, the door opening time column C22 at the time of consideration of the walking time may be separately managed, and may be used as a table common to each car.

  The normal door opening time limit column C21 is a column for managing a normal door opening time t2 in which the door 11 (41) is opened after the elevator 1 arrives at the landing 4. When the normal door-opening time limit t2 has passed, the elevator 1 closes the door 11 (41) and leaves. The normal door-opening time limit t2 is set to be equal to or longer than the registration delay time t1. If the passenger gets into the car 10 and operates the door closing button before the normal door opening time limit t2 expires, the elevator 1 closes the door 11 and leaves.

The door opening time limit column C22 at the time of consideration of the walking time takes a door opening time t3 in consideration of the time required for the user who registered the destination floor call to move from the destination floor registration device 20 to the landing door 41 of the predetermined car 1 It is a field to manage. The door opening time t3 when the walking time is considered is updated each time the door opening time is extended in consideration of the walking time t5 in which the destination floor call is assigned to the car until the grace time t1 elapses. A normal door opening time limit t2 is set as an initial value to the value of the door opening time t3 when the walking time is taken into consideration, and the maximum door opening time limit t4 is changed as the maximum value. The maximum opening time limit column C23 is a column for managing the upper limit value t4 of the waiting time of the elevator 1 which has arrived at the platform 4 with the door 11 open. Even when the ordinary door opening time limit t3 is extended in consideration of the walking time t5, the maximum door opening time limit t4 can not be exceeded.
In this embodiment, the registration delay time t1, the normal door opening time limit t2, the door opening time t3 when the walking time is considered, and the maximum door opening time limit t4 are set to be longer in this order (t1 ≦ t2 ≦ t3 ≦ t4. ).

  The door open time limits t2 and t4 managed by the door open time limit management table T2 can be set in conjunction with the grace period t1 set by the time limit management processing unit 324. Thereby, even when the value of grace time is adjusted according to the change of the use condition of each floor, each door-open time limit can be automatically changed according to the change of the grace time.

  FIG. 5 is an explanatory view showing the relationship between the walking time, the registration delay time, and the door open time period. Here, a plurality of elevator cars 1A to 1N are arranged at the landing 4 (1) on the first floor.

  A plurality of destination floor registration devices 20A, 20B are installed on the first floor. One destination floor registration device 20A is at a distance LA from the landing 4 (1). The other destination floor registration device 20B is away from the landing 4 (1) by the distance LB (> LA). Here, the distances LA and LB may be defined as the shortest distance between the landing 4 (1) and the destination floor registration device 20A, 20B, or may be generally defined as the distance followed by the user.

  The distances between the row front floor registration devices 20A and 20B and the landing doors 41 (1A) to 41 (1N) of the aircrafts 1A to 1N are different from each other. Here, it is assumed that the landing doors 41 (1A), 41 (1B), 41 (1C), and 41 (1N) are closer to the row next floor registration devices 20A and 20B, respectively.

  The time limit management tables T3A and T3B for the destination floor registration devices 20A and 20B are shown above the units 1A to 1N. One time limit management table T3A is a walking time t5 required to move from one destination floor registration device 20A to the landing doors 41 (1A) to 41 (1N) of each of the machines 1A to 1N, and each car 1A to 1N The relationship between the grace period time t1 and the maximum door opening time period t4 is shown. Similarly to the table T3A, the other time limit management table T3B also has a walking time t5 required to move from the other destination floor registration device 20B to the landing doors 41 (1A) to 41 (1N) of the respective machines 1A to 1N; The relationship between grace time t1 and the maximum door-opening time limit t4 in each machine 1A-1N is shown.

  Each column of each table T3A and T3B corresponds to the elevators 1A to 1N. The rightmost column corresponds to the car 1N, the second column from the right corresponds to the car 1C, the third column from the right corresponds to the car 1B, and the fourth column from the right corresponds to the car 1A.

  Attention is paid to one destination floor registration device 20A. The case where the user 5A registers the destination floor in the destination floor registration device 20A and moves to the landing 4 (1) will be described. When the assignment destination of the call on the destination floor is the elevator 1A, it takes seven seconds for the user 5A to reach the landing door 41 (1A). The grace time t1 is 3 seconds. The maximum door open time limit t4 is 10 seconds (7 + 3 = 10). In this floor (the first floor), the grace time t1 in the case of registering the destination floor call in the destination floor registration device 20A is set to 3 seconds. When Unit 1B is assigned to a destination floor call, it takes 8 seconds for user 5A to reach landing 41 (1B), and grace time t1 is set to 3 seconds, so the maximum door open time limit t4 is 11 seconds. And (8 + 3 = 11). When the unit 1C is assigned to the destination floor call, it takes 9 seconds for the user 5A to reach the landing 41 (1C). Therefore, the maximum door open time limit t4 in this case is 12 seconds (9 + 3 = 12). When the unit 1N is assigned to the destination floor call, the maximum opening time limit t4 is 13 seconds (10 + 3 = 13) since the walking time t5 is 10 seconds and the grace time t1 is 3 seconds.

  Attention is paid to the other destination floor registration device 20B. On this floor, the grace time t1 at which the destination floor call can be registered in the destination floor registration device 20B is set to 3 seconds. When the assignment destination of the destination floor call is the unit 1A, since the walking time t5 is 10 seconds and the grace time t1 is 3 seconds, the maximum door opening time limit is 13 seconds. In the case where the destination floor call assignment destination is the car 1B, the maximum opening time limit t4 is 14 seconds since the walking time t5 is 11 seconds and the grace period t1 is 3 seconds. In the case where the destination of the call on the destination floor is 1C, since the walking time t5 is 12 seconds and the grace time t1 is 3 seconds, the maximum door opening time limit t4 is 15 seconds. When the destination of the call on the destination floor is the machine 1N, since the walking time t5 is 13 seconds and the grace time t1 is 3 seconds, the maximum door opening time limit t4 is 16 seconds.

  The walking time t5 may be set as a fixed value from the distances LA, LB between the destination floor registration devices 20A, 20B and the landing 4 or, as described in FIG. 5, the destination floor registration devices 20A, 20B and each landing door It may be determined according to the distance from 41 (1A) to 41 (1N). Alternatively, the walking time of the user may be analyzed using an image sensor or the like, and the analysis result may be used as the walking time value, or the learning result of the daily use situation may be reflected in the walking time.

  In addition, although the grace period t1 is a common value in each car 1 in FIG. 5, it may be a different value. Further, the grace period time limit t1 may be a different value for each destination floor registration device. If this is a destination floor registration device close to a car, even if the destination floor is registered after arrival of each unit, the user can get on in a short time, usually within the door open time limit t2 or the maximum door open time limit t4. This is because the expected value for getting on board is high.

  FIG. 6 is a time chart showing the relationship between the registration grace time, the walking time, the door opening time limit, and the maximum door opening time limit. The horizontal axis in the figure indicates the passage of time, and is based on the time T0 when the car 1A arrives at the first floor, which is the landing floor.

  The time T1 is the time when the grace time t1 has elapsed from the arrival time T0 of the car. The time T2 is a time when a normal door opening time limit t2 has elapsed from the arrival time T0 of the car. The time T3 is the time when the walking time t5 has elapsed from the arrival time T0 of the car, that is, the time when the door opening time t3 when the walking time is taken into consideration from the time T0. The time T4 is the time when the maximum door-opening time limit t4 has elapsed from the arrival time T0 of the car.

  FIG. 6 shows the case where the users 5A to 5E get in the car 1A that has arrived at the landing floor at time T0. The positions of the users 5A to 5E in FIG. 6 indicate the times when the destination floor call is registered in the destination floor registration device 20 (when the destination floor call occurs). The physical position of each user at the time of occurrence of the destination floor call is the installation place of the destination floor registration device 20. Here, each of the users 5A to 5E is only arranged for the explanation of the context with the grace period t1, and the registration with the destination floor registration device is performed at different timings without actually continuing. It shall be.

  The user 5A who registered the destination floor before the arrival of the car 1A is located on the left side of the car 1A. The user 5B who has registered the destination floor almost simultaneously with the arrival of the unit 1A is located corresponding to the arrival time of the unit 1A. The user 5C who has registered the destination floor before the unit 1A has arrived and the grace time t1 has elapsed is located on the right side of the unit 1A and at a time before the expiration of the grace time t1. The user 5D who has registered the destination floor after the grace period t1 of the number 1A has elapsed is located on the right side of the number 1A and at the time when the grace period t1 has passed. The user 5E has registered the destination floor before arrival of the aircraft 1A, but has arrived at the landing 4 (1) after the maximum door opening time limit t4 of the aircraft 1A has elapsed because the moving speed is slow.

  Even if the user 5A considers the walking time, the user 5A can get into the car 1A by the time T2 when the normal door-opening time limit t2 in the car 1A expires. Specifically, when the time from registration to arrival of the car 1A is t6, it is possible to walk to the car from the registration to the arrival of the car. In this case, since the walking time t5 to t6 is reduced and t2> t5-t6, the user 5A can get into the vehicle 1A by the time T2 when the normal door opening time period t2 expires. Therefore, in the case of the user 5A, the door is closed at time T2 when a normal door opening time limit t2 has elapsed from the arrival time T0 of the car.

  The user 5B has registered the destination floor call at the timing when the car 1A arrives at the landing (1). Therefore, the time t6 from the above registration to the arrival of the elevator 1A is zero. In this case, since the normal door opening time limit t2 <walking time t5-t6 (= 0), the user 5B can not get into the vehicle 1A by the expiration time T2 of the normal door opening time limit t2. However, if the door opening time limit is extended from the normal door opening time limit t2 to the door opening time t3 when the walking time is taken into consideration, the user 5B receives the door opening time t3 when the walking time is taken into consideration. As we can get on 1A, we close the door at time T3

  The user 5C has registered the destination floor call after the car 1A arrives at the platform. The destination floor call is generated within the registration delay time t1 and can therefore be registered in the elevator 1A. However, in consideration of the walking time t5, the user 5C can not normally get into the car within the door opening time t2. Specifically, the time t6 from the registration of the destination floor call to the arrival of the machine 1A becomes a negative value since the destination floor call is registered after the arrival of the machine 1A, and t2 <t5-(-t6), which is t2. Beyond. Here, even if the door opening time t3 at the time of considering the walking time is applied, the maximum value is the maximum door opening time limit t4. Therefore, when the condition of t4 ≧ t5-(-t6) is satisfied, the user 5C can get into the vehicle 1A by the time T4 when the maximum door-opening time limit t4 expires. Conversely, if (t5-(-t6)) exceeds t4 when the above condition is not satisfied, the car 1A is not assigned to the destination floor call of the user 5C. This is because if the door opening time is too long, the operation efficiency is lowered and the other users who are already in the car feel uncomfortable.

  Since the user 5D has registered the destination floor call after the grace time t1, the user 5D can not get into the vehicle 1A by the time T4 when the maximum opening time period t4 expires, considering the walking time t5. For this reason, the car 1A is not allocated to the destination floor call after the expiration time T1 of the grace time t1.

  The user 5E has registered a destination floor call before the arrival of the car 1A, and the car 1A is assigned to the car by the same calculation as the above 5A. However, when the walking speed is slow or when stopping at another place, it may not be possible to get into the vehicle 1A by the time T4 when the maximum opening time limit t4 expires. In this case, the car 1A closes the door at time T4 and leaves. The destination floor call of the user 5E is assigned to the next machine. When the assigned machine number is changed, a change in the assigned machine number may be notified to the user 5E from a display or the like installed at the landing. It should be noted that the confirmation that the user 5E is not on board the unit 1A is that the weight sensor of the unit 1A detects that the weight is insufficient, or the wireless sensor is used with the users in the car It can be detected that 5E is not on board the vehicle 1A by comparing the persons.

  As described in FIG. 6, according to the present embodiment, in a crowded floor with many users (for example, the first floor at the time of work), departure due to a small number of passengers can be suppressed, and extension of unnecessary ride-in time is suppressed. be able to. Therefore, according to the present embodiment, it is possible to simultaneously improve the operation efficiency and the service quality.

  Even in the present embodiment, even a user who could not get on in the past because of the slow walking speed can extend the door open time limit in consideration of the walking time, and therefore can get on the train. Therefore, in the present embodiment, the possibility of getting on the user can be enhanced, and the quality of service is improved. Furthermore, the operating efficiency can be improved because the boarding rate can be increased.

  Furthermore, in the present embodiment, since the registration of the destination floor call is not permitted after the grace period has elapsed, the door open period is not unnecessarily extended. Therefore, the delay in departure can be suppressed to improve the quality of service, and the wasteful waiting time can be reduced to improve the transportation efficiency.

  The operation management control unit 32 according to the present embodiment includes the walking time setting unit 321 and the registration postponement time setting unit 320, and thus can provide efficient services according to the usage situation. As described above, at the congested landings in congested time zones, the boarding rate can be increased by setting the grace period long or extending the door-open period in consideration of the walking time. Alternatively, on the congested floor in the congested time zone, the door open time limit of all the units or at least some of the units may be extended to the maximum open time limit.

  In this embodiment, since the registration grace time setting unit 320 for setting the grace time for each floor or each car is provided, the allocatable machine selection unit 322 uses only the destination floor call that occurred before the grace time expires. It can be assigned. Therefore, according to the present embodiment, the assignable car selection unit 322 can select the car candidate based on whether or not the occurrence time of the destination floor call is within the grace time, and the candidate selection process is simplified. Can be

  In the present embodiment, on a floor with a large traffic volume, the travel time can be improved by relatively increasing the grace period to improve the operation efficiency. On the other hand, on floors with low traffic volume, the grace period can be reduced to make it easier to answer calls on other floors. Therefore, compared to the case of uniformly setting the grace time, in the present embodiment, it is possible to prevent the time required for moving to another floor to be long, and to improve the quality of service.

  The second embodiment will be described with reference to FIG. Since this embodiment corresponds to a modification of the first embodiment, the difference from the first embodiment will be mainly described. In the present embodiment, a value obtained by subtracting the walking time t5 from the maximum opening time limit t4 is set as the grace time t1.

  FIG. 7 is an explanatory view showing the relationship between the walking time, the registration grace time, and the door opening time limit. The relationship between the landing doors 41 (1A) to 41 (1N) of the units 1A to 1N, the destination floor registration devices 20A and 20B, and the configurations of the tables T3A and T3B are the same as those in FIG.

  In the example of FIG. 5, the grace period t1 is set in units of floors separately for the destination floor registration devices 20A and 20B. For example, in the first floor destination floor registration device 20A shown in FIG. 5, the same grace period t1 of 3 seconds is set for all the first floor machines 1A to 1N. Similarly, in the first floor destination floor registration device 20B shown in FIG. 5, the same grace period t1 of 3 seconds is set for all the first floor machines 1A to 1N.

  On the other hand, in the present embodiment, the grace period t1 by the registration grace period setting unit 320 is set for each car. For example, when using the destination floor registration device 20A, the grace time t1 of the machine 1A is 8 seconds, the grace time t1 of the machine 1B is 7 seconds, the grace time t1 of the machine 1C is 6 seconds, and the machine 1N The grace period t1 is 5 seconds.

  When the destination floor registration device 20B is used, the grace time t1 of the machine 1A is 5 seconds, the grace time t1 of the machine 1B is 4 seconds, the grace time t1 of the machine 1C is 3 seconds, and the grace time of the machine 1N is The time t1 is 2 seconds.

  Regardless of which destination floor registration device 20A, 20B is used, the same maximum door opening time limit t4 is set for all the machines 1A to 1N. In the present embodiment, the maximum door opening time limit t4 is set to, for example, 15 seconds. The grace period t1 of each of the cars 1A to 1N is calculated by subtracting the walking time t5 from the maximum door opening time period t4 (t1 = t4-t5).

  According to the setting of such a grace time t1, when the walking times t5 from the plurality of destination floor registration devices 20A and 20B to each of the machines 1A to 1N are different from each other, the grace time is uniformly uniform for all cars. More efficient grace time can be set for each car than setting t1. For this reason, in the present embodiment, it is possible to prevent the time required for moving to another floor from being unnecessarily long for each car, and more efficient operation can be performed.

  The present invention is not limited to the embodiments described above, but includes various modifications. For example, the embodiments described above are described in detail in order to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the configurations described.

  In each of the embodiments described above, in order to simplify the description, control using the operation management control unit 32 is always performed. Instead of this, the control by the operation management control unit 32 may be performed only at predetermined congestion such as use of the restaurant floor at the time of leaving work or at lunch time. Alternatively, in the non-congested time zone, the grace period t1 on the first floor, the third floor, and the fifth floor illustrated in FIG. 3 may be set to 0 seconds.

  Furthermore, for example, the door-open period may be controlled not only at work or at work but also at the end of an event such as lunch or seminar. In the congested halls of congested time zones, by setting the grace period long or extending the door open time period in consideration of the walking time, it is possible to increase the riding ratio and to improve the operation efficiency. In addition, since it is possible to prevent passengers from being late, it is possible to maintain service quality.

  Furthermore, among the plurality of floors, the door opening time limit is set to the maximum door opening time limit on the floor that is most congested, and on the other floors, the grace period t1 is set according to the number of users, and the walking time t5 is considered. And may be extended.

  Furthermore, although the destination floor registration device 20 has been described in this embodiment, the destination floor reading unit 21 may be provided at the entrance gate of the building, and the destination floor may be automatically input from the employee number read from the employee ID card. In the case of this configuration, when entering from a plurality of banks to a bank where group management is carrying out operation management, it is possible to prevent a user from being late in the ride.
