An elevator group management system comprising a destination floor registration device that registers a destination floor before boarding and a group management device that manages a plurality of cars and a destination floor registration device, the group management device being a destination floor registration device A registration grace time setting unit that sets at least a registration grace time that can be assigned to each car arriving at a predetermined floor for a destination floor call to be generated, and registration of each car arriving at the predetermined floor for a destination floor call Select at least one car from each car before the grace period expires, determine the assigned car to assign the destination floor call from the selected car, and assign the destination floor call to the assigned car And, equipped with a.

  According to the present invention, only destination floor calls that occur within the registration grace time are assigned to the car, and destination floor calls that have passed the registration grace time are not assigned to the car. Therefore, it is possible to suppress the occurrence of a situation in which the destination floor call is assigned to the car and the departure of the car is delayed even after the registration grace time. As a result, service quality and operation efficiency can be improved.

It is a whole block diagram of an elevator group management system. It is a flowchart of an operation management control process. It is a structural example of the table which sets registration grace time. It is a structural example of the table which manages a door opening time limit. It is explanatory drawing which shows the relationship between walk time, registration postponement time, and a door opening time limit. It is a time chart which shows the relationship between registration postponement time, walking time, door opening time limit, and maximum door opening time. It is explanatory drawing which concerns on 2nd Example and shows the relationship between walk time, registration postponement time, and a door opening time limit.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As described in detail below, the elevator group management system of the present embodiment controls a plurality of units 1 (A) to 1 (N) and each unit 1 (A) to 1 (N). A device 15 and a group management device 3 that determines the number of cars that can be boarded for the destination floor call acquired by the destination floor registration system 2 are provided. The group management device 3 assigns a destination floor call generated between the arrival of the car and the elapse of the registration grace time to any one of the cars. And the group management apparatus 3 outputs the predetermined | prescribed instruction | command regarding a predetermined car based on the predetermined | prescribed door opening time limit and destination floor call which are set with respect to the predetermined car which allocated the destination floor call. Thereby, in this embodiment, only the destination floor call within the registration grace time is permitted, so it is possible to avoid delaying the departure of the car, and to improve both the operation efficiency and the service quality of the plurality of cars as a whole. it can.

  According to the present embodiment, only the destination floor call generated within the registration grace time is permitted, and the door opening time is extended in consideration of the walking time from the destination floor registration device to the platform at the landing. Therefore, according to the present embodiment, since a new destination floor call generated within the registration grace time can be assigned to the car (unit) assigned to the destination floor call, the number of passengers can be increased. It is possible to suppress the delay of departure.

  A first embodiment will be described with reference to FIGS. FIG. 1 shows the overall configuration of an elevator group management system according to this embodiment. The elevator group management system includes a plurality of elevator cars 1 (A) to 1 (N), a car control device 15 that controls each car 1 (A) to 1 (N), a destination floor registration system 2, a group The management apparatus 3 is provided. Hereinafter, the elevator unit is abbreviated as “unit”. In the case where the machines 1 (A) to 1 (N) are not particularly distinguished, they are called the machine 1.

  Unit 1 transports users by moving up and down between a plurality of floors. Hereinafter, the floor may be abbreviated as a floor. The machine 1 includes, for example, a car 10, a hoisting machine 12 that winds and unwinds the car 10 using the main rope 13, and a counterweight 14 that moves up and down in the opposite direction to the car 10 according to the movement of the main rope 13. With.

  The car 10 is provided with a door 11 that can be opened and closed. 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 arriving at the landing 4, the car 10 stands by with the door 11 opened for a predetermined time. Waiting for the platform 4 with the car 10 with the door 11 open is referred to as door opening standby. When the boarded user (passenger) operates a door closing button (not shown) of an operating device in the car 10 or the maximum door opening time elapses, the car 10 closes the door 11. The landing door 41 is also closed by the closing operation. When the car 10 is in the door-closed state, the car 10 leaves the landing 4 and moves to the floor designated by the destination floor call. The car control device 15 takes charge of opening / closing and moving the car 10. The machine control device 15 controls the open state of the car 10 in response to a command from the group management device 1.

  The destination floor registration system 2 is a system for inputting and registering the destination floor intended by the user to 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 terminal 23.

  The landing destination floor registration device 20 is a device that is installed, for example, in the vicinity of a corridor of a building, in the vicinity of a building entrance / exit, in the vicinity of a landing 4 or the like. Hereinafter, the destination floor registration device 20 may be abbreviated. 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 a user to input a numerical value indicating a destination floor. The input device 200 is composed of, for example, a numeric keypad. The display device 201 is a device that displays a value input from the input device 200 and displays a number assigned to the input destination floor. The display device 201 includes, for example, a liquid crystal display, an organic EL (OLED: Organic Light-Emitting Diode) display, and the like. The special button 202 is a button for inputting special circumstances, for example, with a small child, with a wheelchair user, with a sick person, or with heavy luggage. The user can also input the number of people scheduled to board from the input device 200.

  The configuration of the input device 200, the display device 201, and the special button 202 is 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.

  Returning to FIG. The destination floor reading unit 21 communicates with the destination floor registration device 20 to receive 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. Or 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 information on the car 1 to which the destination floor call is assigned by the group management device 3 to the destination floor registration device 20.

  The input / output control system 22 is located between the destination floor reader 21 and the group management device 3 and is in charge of information input / output between the destination floor reader 21 and the group management device 3. The input / output control system 22 may be considered as a subsystem of the group management device 3, or may be considered as a system independent of both the group management device 3 and the destination floor registration system 2.

  A tag or terminal 23 may be used instead of or together with the destination floor registration device 20. 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, or a tablet PC.

  For example, in the case of an IC tag or IC card type employee ID, a destination floor reader 21 may be provided at the entrance gate of a building, and the destination floor may be automatically set from the employee number read from the employee ID. For example, the group management device 3 holds a table for managing a set of employee numbers and floors, 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 number machine 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.

  Hereinafter, functions realized as a result of cooperation between the hardware and software described above will be described. The group management device 3 includes, for example, a learning system 30, an intelligent system 31, and an operation management control unit 32 in addition to the normal function as an elevator group management device.

  The group management device 3 monitors and stores the daily operation status of each unit 1 as one of normal functions. For example, the learning system 30 determines whether the current operation pattern corresponds to a known operation pattern by analyzing and learning the current operation status data. The intelligent system 31 detects an unknown operation pattern by analyzing the operation status data. For example, when tenants in a building are changed, the time and frequency of using an elevator change, and a new operation pattern is born. When the intelligent system 31 detects a new operation pattern, it notifies the learning system 30.

  The operation management control unit 32 assigns the unit 1 to the destination floor call and manages the door opening time of each unit 1. 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 for setting a registration grace time for each floor or for each period. Here, the registration postponement time is a time during which a 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 occurs at a certain time T0, the registration postponement time t1 starts from that time T0. At the time T1 (= T0 + t1) when the registration postponement time t1 expires, the destination floor call is not assigned to the machine whose registration postponement time t1 expires.

  In other words, the registration grace time setting unit 320 sets a grace time for determining to what time registration of the destination floor call is permitted for the candidate cars that can be assigned without being excluded by the allocatable machine selection unit 322. To do.

  Returning to FIG. The walking time setting unit 321 sets the walking time. The walking time as an example of “traveling time” 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 according to the distance from each destination floor registration device 20 to 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 unit 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 a case where the walking speed becomes slower than the standard walking speed, such as when traveling with a small child or carrying heavy luggage. You can also. When the installation location of the destination floor registration device 20 is changed or when the destination floor registration device 20 is newly installed, the walking time setting unit 321 sets the walking time.

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

The allocatable car selection unit 322 selects at least one car from each car 1 that can be assigned a destination floor call. As will be described later with reference to FIG. 2, the allocatable machine selection unit 322 extracts assignable car candidates based on at least one preset exclusion condition. Specifically, for each of a plurality of exclusion conditions set in advance, an unsuitable number is assigned to the destination floor call and removed from the assignable number candidates. As will be described later with reference to FIG. 2, the exclusion condition is, for example, whether the registration grace period has elapsed and preparation for departure is in progress (S3), or is expected to be full (S5), or the user is not in time for the landing (S7).
The car 1 corresponding to any of the exclusion conditions is excluded from the car candidates that can be assigned the destination floor call. Only units that have cleared all the exclusion conditions are selected as candidate units that can be assigned destination floor calls.

  The destination floor registration processing unit 323 selects one of the number 1 that can be operated optimally from the assignable number candidate cars, and assigns and registers a destination floor call to the selected number 1. Whether the car 1 is capable of optimal operation is determined in consideration of, for example, a car call or a landing call assigned to the car 1 and the number of passengers (or total load) of the car 1.

  The command unit P3 is a function for issuing a predetermined command to the car 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 opening command processing unit 325.

  The time management processing unit 324 manages elements related to time management such as a registration grace time, a walking time, and a door opening time. The door opening command processing unit 325 sends a command for applying the door opening time limit used for the numbered vehicle 1 assigned to the destination floor call to the numbered vehicle control device 15.

  In addition, as will be described later with reference to FIG. 2, the command unit P3 transmits information for specifying the car 1 assigned the destination floor call to the destination floor registration device 20 for guidance (S10), or near the landing door 41. The planned stoppage floor of Unit 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 other functions 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, and 32 is not limited to the above example. In short, the registration grace time can be set for each floor or for each unit (for each landing door), and the destination floor that occurred between the time when Unit 1 arrived at platform 4 and the registration grace time passed. Any configuration can be used as long as a call can be assigned to any one of the cars 1.

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

  Similar to the group management device having a normal configuration, the group management device 3 of the present embodiment receives unit data from each of the unit control devices 1 (A) to 1 (N) (S1). The unit data is data relating to the state and operation of the unit 1, and includes, for example, a moving direction, a total load, a car call state, a door open / closed state, and the like.

  The group management device 3 grasps the status of each unit based on each unit data received in step S1, and then determines whether the destination floor call by the landing destination floor registration device 20 is registered via the input / output control system 22. (S2). If the destination floor call is not registered (S2: NO), it is not necessary to assign the car number 1, so the process proceeds to step S10.

  When the destination floor call is registered (S2: YES), the group management device 3 assigns one unit 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 condition as an allotted car candidate (S3 to S8). In this embodiment, three exclusion conditions are provided. Not limited to this, four or more exclusion conditions may be set.

  The allocatable unit selection unit 322 determines whether there is a unit 1 that is in preparation for departure after the registration postponement time t1 set by the registration postponement time setting unit 320 has expired for all units 1. S3). In the present embodiment, the destination floor call is not assigned to the machine 1 that has passed the registration grace time. This is to prevent departure delay.

  If the allocatable car selection unit 322 determines that there is a car 1 that is ready for departure after expiration of the registration grace period (S3: YES), the car 1 is excluded from candidates for the car assigned to the destination floor call (S4). On the other hand, if the allocatable machine selecting unit 322 determines that there is no car 1 corresponding to the exclusion condition in step 3 (S3: NO), it skips step 4 and proceeds to step S5.

  The allocatable unit selection unit 322 determines whether there is a unit that is expected to be full for all the units 1 that are not excluded from the allotted unit candidates (S5). Full is the state where the maximum capacity of the car 10 is reached. The group management device 3 can estimate the number of users (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 a user registers a destination floor in the destination floor registration device 20, it is possible to count one person's input as one person and detect the number of passengers scheduled to board. You may make it possible to input the number of users. Based on the detected planned number of passengers, the group management device 3 can predict whether or not the car 10 of the car 1 will be full based on the average weight of the users.

  If the allocatable unit selection unit 322 determines that there is a unit 1 in which the car 10 becomes full when one or more users who have registered the destination floor call are on board (S5: YES), there is a risk of being full Is removed from the candidate for assigned number (S6). On the other hand, if 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 car selection unit 322 is the walking required for the user who registered the destination floor call in the destination floor registration device 20 to reach the landing door 41 for all the cars 1 that are not excluded from the assigned car candidates. The time t5 is compared with a total value of the estimated arrival time required for the determination target machine 1 to arrive at the floor where the destination floor call is registered and the preset maximum opening time t4 (walking time> (Estimated arrival time + maximum door opening time)). The allocatable machine selection unit 322 can use the walking time set by the walking time setting unit 321 when determining in step S7.

  When the allocatable unit selection unit 322 determines that the walking time is larger than the sum of the estimated arrival time of the unit 1 and the maximum door opening time (S7: YES), the allotted unit is excluded from the allotted unit candidates (S8). ). In this case, it takes a long time for the user who registered the destination floor call to reach the landing door 41 (> estimated arrival time + maximum door opening time), the departure is delayed, and other users who have already boarded This is because the service quality of the service is reduced. On the other hand, when the allocatable unit selection unit 322 determines that the walking time of the user who registered the destination floor call is less than or equal to the total value of the scheduled arrival time of the unit 1 and the maximum door opening time (S7: NO), Step S8 is skipped and the process proceeds to step S9.

  When the destination floor registration processing unit 323 receives the information on the candidate cars extracted by the allocatable machine selection unit 322, the destination floor registration processing unit 323 selects one of the most appropriate cars for assigning the destination floor call from the car number candidates (S9). . For example, the destination floor registration processing unit 323 selects one unit using as a selection criterion the unit having the fastest time to arrive at the floor where the destination call is generated, the unit having the smallest total load, and the like.

  Further, the destination floor registration processing unit 323 gives the door opening time limit information used for determining the assigned number machine in step S7 from the time limit management processing unit 324 to the door opening command processing unit 325. The door opening command processing unit 325 gives a command to the number control device 1 of the number assigned to the destination floor call so as to execute the door opening time period corresponding to the exclusion condition of step S7.

  Thereafter, the group management device 3 executes the number machine guidance process (S10) and the scheduled stop floor display process (S11), and ends this process. In the car number guidance process in step S10, information specifying the car number assigned the destination floor call 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 alerting | reporting part 211 may notify a user of the information (unit number) of the number machine to which the destination floor call was assigned through a display and audio | voice output apparatuses, such as a mobile telephone and a portable information terminal which a user holds. The user moves toward the landing door 41 of the guided car.

  At the planned stop floor 4 in step S11, the planned stop floor of each unit 1 can be displayed. For example, the group management device 3 can display the planned stoppage floor of each unit 1 using a display installed at the landing 4 or an indicator lamp installed near the landing door 41. The user who arrives at the landing 4 confirms the stop floor of the number 1 notified in step S10 and stands by there.

  FIG. 3 shows a configuration example of the 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 manages, for example, a floor column C10, a user number column C11, and a grace time column C12 in association with each other. In this embodiment, the grace time value t1 is set in the grace time column C12 according to the number of users on each floor. In the present embodiment, for example, the threshold value for the number of users is set to 50, and a value obtained by dividing the value in the number of users column C11 by the threshold value for the number of users is calculated as the grace time t1 (grace time t1 = number of users / number of users). Threshold).

  In the number-of-users column C11, the number of users can be set based on the learning result of 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 5 minutes, every 10 minutes, or every 30 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 shows, for example, a grace time at work.

  At a certain time point shown in FIG. 3 (for example, morning attendance time), the number of users on the first floor is the largest “250 people”, and the quotient divided by the threshold “50 people” is “5”. Accordingly, the grace time for the first floor is set to “5 seconds”.

  On the other hand, the number of users on the second floor is relatively small at “20 people”, and the quotient divided by the threshold value “50 people” is “0”. Accordingly, the grace time for 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 time for the fourth floor is also set to “0 seconds”. Since the number of users on the third floor is “60 people”, the quotient divided by the threshold value “50 people” is “1”. Therefore, the grace time on the third floor is set to “1 second”. Since the number of users on the fifth floor is “50 people”, the quotient divided by the threshold value “50 people” is “1”. Accordingly, the grace time for the fifth floor is also set to “1 second”.

  The grace time t1 set in the grace time column C12 starts from the time when the car 1 arrives at the landing 4. For example, on the first floor, counting starts when the car arrives at the landing, and the grace time expires after 5 seconds. If the user registers a destination floor call before the grace period t1 expires, the destination floor call can be assigned to the relevant car, so the user can get on that car. On the other hand, for a destination floor call registered by the user after the expiration of the grace period t1, the destination floor call is not assigned to the relevant unit, and the user cannot get on that unit.

  If the grace time t1 is set to a large value, the time until the car 1 departs from the floor becomes longer. Therefore, in the present embodiment, in the floor where the traffic volume is small, the value of the grace time t1 is set to be small so that it is easy to answer calls on other floors. On the other hand, on the floor with a lot of traffic, by setting the value of the grace time t1 to be relatively large, passengers can easily get into the car 10 and the boarding rate is increased. As a result, in this embodiment, the waiting time in the door open standby state is shortened on the floor with few users to speed up the departure of the machine 1, and the door waiting in the door open standby state is increased on the floor with many users. The rate can be improved. Thereby, in a present Example, both service quality and transport efficiency (operation efficiency) can be improved.

  The user number threshold value may be a fixed value or may be changed according to the operation status. 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, the maximum number of passengers in the car (maximum load), or the building described in Japanese Industrial Standards You may calculate from the traffic calculation method used for an installation plan.

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

  FIG. 4 shows an example of a table T2 for managing the door opening time limit. The door opening time management table T2 manages, for example, a floor column C20, a normal door opening time column C21, a door opening time column C22 when considering walking time, and a maximum door opening time column C23. In FIG. 4, the door opening time of Unit 1 on the first floor is shown, and illustration of other floors and other unit door opening time is omitted. In addition, since it is only the door opening time column C22 when walking time is taken into consideration that different cases are surely generated by each unit, the normal door opening time column C21 and the maximum door opening time column C23 for each floor of each unit Are the same, the door opening time column C22 when considering the walking time may be separately managed and used as a table common to each unit.

  The normal door opening time limit column C21 is a column for managing the normal door opening time t2 when the door 1 (41) is opened after the machine 1 arrives at the landing 4. When the normal door opening time t2 has passed, the car 1 starts with the door 11 (41) closed. The normal door opening time period t2 is set to be equal to or longer than the registration grace time t1. If the passenger enters the car 10 and operates the door closing button before the normal door opening time t2 expires, the car 1 starts with the door 11 closed.

In the door opening time limit column C22 when considering walking time, the door opening time t3 considering 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 unit 1 is displayed. It is a column to manage. The door opening time t3 at the time of considering the walking time is updated every time the door opening time is extended in consideration of the walking time t5, with the destination floor call assigned to the car until the grace time t1 elapses. A normal door opening time t2 is set as an initial value for the value of the door opening time t3 when taking the walking time into consideration, and the maximum door opening time t4 is changed as a maximum value. The maximum door opening time limit column C23 is a column for managing the upper limit t4 of the time that the machine 1 that has arrived at the landing 4 can stand by with the door 11 open. Even when the normal door opening time t3 is extended in consideration of the walking time t5, the maximum door opening time t4 cannot be exceeded.
In the present embodiment, the registration postponement time t1, the normal door opening time period t2, the door opening time t3 when considering the walking time, and the maximum door opening time period t4 are set to increase in this order (t1 ≦ t2 ≦ t3 ≦ t4). ).

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

  FIG. 5 is an explanatory diagram showing the relationship between the walking time, the registration grace time, and the door opening time limit. Here, a plurality of Nos. 1A to 1N are arranged at the landing 4 (1) on the first floor.

  A plurality of destination floor registration devices 20A and 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 separated from the landing 4 (1) by a 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 devices 20A and 20B, or may be defined as a distance generally followed by the user.

  The distances between the destination floor registration devices 20A and 20B and the landing doors 41 (1A) to 41 (1N) of the units 1A to 1N are different. Here, it is assumed that the landing doors 41 (1A), 41 (1B), 41 (1C), and 41 (1N) are close to the destination floor registration devices 20A and 20B in this order.

  The time limit management tables T3A and T3B for the destination floor registration devices 20A and 20B are shown on the upper side of the units 1A to 1N. One time management table T3A includes 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 units 1A to 1N, and the units 1A to 1N. The relationship between the grace time t1 and the maximum door opening time t4 is shown. Similarly to the table T3A, the other time 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 units 1A to 1N. The relationship between the grace time t1 and the maximum door opening time t4 in each of the cars 1A to 1N is shown.

  Each column of the tables T3A and T3B corresponds to the number machines 1A to 1N. The rightmost column corresponds to Unit 1N, the second column from the right end corresponds to Unit 1C, the third column from the right end corresponds to Unit 1B, and the fourth column from the right end corresponds to Unit 1A.

  Attention is focused on one destination floor registration device 20A. A 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 destination floor call is assigned to the car 1A, it takes 7 seconds for the user 5A to reach the landing door 41 (1A). The grace time t1 is 3 seconds. The maximum door opening time t4 is 10 seconds (7 + 3 = 10). In this floor (the first floor), a grace period t1 for registering a destination floor call in the destination floor registration device 20A is set to 3 seconds. When Unit 1B is assigned to the destination floor call, it takes 8 seconds for the user 5A to reach the landing 41 (1B), and the grace period t1 is set to 3 seconds, so the maximum door opening time limit t4 is 11 seconds. (8 + 3 = 11). When the car 1C is assigned to the destination floor call, it takes 9 seconds for the user 5A to reach the landing 41 (1C). Accordingly, the maximum door opening time t4 in this case is 12 seconds (9 + 3 = 12). When the unit 1N is assigned to the destination floor call, since the walking time t5 is 10 seconds and the postponement time t1 is 3 seconds, the maximum door opening time period t4 is 13 seconds (10 + 3 = 13).

  Focus on the other destination floor registration device 20B. In this floor, a grace period t1 for registering a destination floor call in the destination floor registration device 20B is set to 3 seconds. When the destination floor call is assigned to No. 1A, since the walking time t5 is 10 seconds and the grace time t1 is 3 seconds, the maximum door opening time is 13 seconds. When the destination floor call is assigned to Unit 1B, the walking time t5 is 11 seconds and the grace time t1 is 3 seconds, so the maximum door opening time t4 is 14 seconds. When the destination floor call is assigned to No. 1C, the walking time t5 is 12 seconds and the postponement time t1 is 3 seconds, so the maximum door opening time t4 is 15 seconds. When the destination floor call is assigned to No. 1N, the walking time t5 is 13 seconds and the grace time t1 is 3 seconds, so the maximum door opening time t4 is 16 seconds.

  The walking time t5 may be set as a fixed value from the distances LA and LB between the destination floor registration devices 20A and 20B and the landing 4 or, as described in FIG. 5, the destination floor registration devices 20A and 20B and the landing doors. You may determine according to the distance with 41 (1A) -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 a walking time value, or the learning result of the daily usage situation may be reflected in the walking time.

  In FIG. 5, the grace period t <b> 1 is a common value in each of the cars 1, but may be a different value. Further, the grace period t1 may be different for each destination floor registration device. If this is a destination floor registration device close to the car, even if the destination floor is registered after the arrival of each unit, the user can get on in a short time, and within normal door opening time t2 and maximum door opening time t4 This is because there is a high expected value that can be boarded.

  FIG. 6 is a time chart showing the relationship between the registration postponement 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 machine 1A arrives at the first floor, which is the landing floor.

  Time T1 is the time when the grace time t1 has elapsed from the arrival time T0 of the car. Time T2 is the time when the normal door opening time period t2 has elapsed from the arrival time T0 of the car. 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 considering the walking time has elapsed from the time T0. Time T4 is the time when the maximum door opening time period t4 has elapsed from the arrival time T0 of the car.

  FIG. 6 shows a case where users 5A to 5E get into 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 time when the destination floor call is registered in the destination floor registration device 20 (the time when the destination floor call occurs). The physical location of each user when the destination floor call is generated is the installation location of the destination floor registration device 20. Here, the users 5A to 5E are merely arranged in order to explain the relationship with the grace period t1, and are actually not consecutive and are registered in the destination floor registration device at different timings. Shall.

  The user 5A who registered the destination floor before arrival of the machine 1A is located on the left side of the machine 1A. The user 5B who registered the destination floor almost simultaneously with the arrival of the machine 1A is positioned corresponding to the arrival time of the machine 1A. The user 5C who registered the destination floor before the grace time t1 after the arrival of the machine 1A is located on the right side of the machine 1A and before the expiration of the grace time t1. The user 5D who registered the destination floor after the grace time t1 of the unit 1A has elapsed is located on the right side of the unit 1A and at the time when the grace period t1 has passed. The user 5E has registered the destination floor before the arrival of the car 1A, but has arrived at the landing 4 (1) after the maximum door opening time t4 of the car 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, assuming that the time from registration to arrival of the car 1A is t6, time for walking to the car can be obtained from the time of registration to the arrival of the car. In this case, t2 is subtracted from the walking time t5 so that t2> t5−t6. Therefore, the user 5A can get into the car 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 the time T2 when the normal door opening time t2 has elapsed from the arrival time T0 of the car.

  The user 5B registers the destination floor call at the timing when the car 1A arrives at the landing (1). Accordingly, the time t6 from the above registration to the arrival of the car 1A is zero. In this case, since the normal door opening time t2 <walking time t5-t6 (= 0), the user 5B cannot get into the car 1A by the expiration time T2 of the normal door opening time t2. However, when the door opening time period is extended from the normal door opening time period t2 to the door opening time time t3 when considering the walking time, the user 5B will start the machine by the time T3 when the door opening time period t3 when considering the walking time expires. Because it is possible to board 1A, the door is closed at time T3.

  User 5C has registered the destination floor call after No. 1A arrives at the landing. Since the destination floor call has occurred within the registration postponement time t1, it can be registered in the machine 1A. However, considering the walking time t5, the user 5C cannot get into the car during the normal door opening time t2. Specifically, the time t6 from the registration of the destination floor call to the arrival of the car 1A is a negative value because the destination floor call is registered after the arrival of the car 1A, and t2 <t5 − (− t6) and t2 Will be exceeded. Here, even if the door opening time t3 when considering the walking time is applied, the maximum value is the maximum door opening time t4. Therefore, when the condition of t4 ≧ t5-(− t6) is satisfied, the user 5C can get into the car 1A by the time T4 when the maximum door opening time period t4 expires. Conversely, when the above condition is not satisfied and (t5 − (− t6)) exceeds t4, the machine 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 other users who are already in the car are uncomfortable.

  Since the user 5D has registered the destination floor call after the grace period t1, considering the walking time t5, the user 5D cannot get into the unit 1A by the time T4 when the maximum door opening time t4 expires. For this reason, No. 1A is not assigned to the destination floor call that has passed the expiration time T1 of the grace period t1.

  The user 5E registers the destination floor call before the arrival of the number 1A, and the number 1A is assigned to this destination call by the same calculation as the above 5A. However, if the walking speed is slow or if you stop by another place, you may not be able to get into Unit 1A by time T4 when the maximum door opening time t4 expires. In this case, the machine 1A departs with the door closed at time T4. The destination floor call of the user 5E is assigned to the next machine. When the assigned car number is changed, it is only necessary to notify the user 5E of the change of the assigned car number from an indicator or the like installed at the landing. Here, the confirmation that the user 5E is not in the No. 1A is that the weight sensor of the No. 1A detects that the weight is insufficient, or the use assigned to the user in the car by the wireless sensor. By comparing the persons, it is possible to detect that 5E is not in the car 1A.

  As described in FIG. 6, according to the present embodiment, it is possible to suppress departure by a small number of passengers on a crowded floor with many users (for example, the first floor at work time) and suppress unnecessary extension of boarding time. be able to. Therefore, according to this embodiment, it is possible to achieve both improvement in operation efficiency and improvement in service quality.

  Even in a user who could not get in until now because the walking speed is slow, in this embodiment, the door opening time can be extended in consideration of the walking time, so that the user can get on. Therefore, in this embodiment, it is possible to increase the user's possibility of boarding and improve the service quality. Furthermore, since the boarding rate can be increased, the operation efficiency can be improved.

  Furthermore, in this embodiment, since the registration of the destination floor call is not permitted after the grace period has elapsed, the door opening time is not unnecessarily extended. For this reason, it is possible to improve the service quality by suppressing the delay of departure, and it is possible to reduce the wasteful waiting time and increase the transportation efficiency.

  Since 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, it is possible to provide an efficient service according to the use situation. As described above, the boarding rate can be increased by setting the grace time longer or extending the door opening time in consideration of the walking time at the crowded platform in the crowded time zone. Alternatively, on the crowded floor in the crowded time zone, the door opening time of all the units or at least some of the units can be extended to the maximum door opening time.

  In this embodiment, since a registration grace time setting unit 320 for setting a grace time for each floor or for each unit is provided, the allocatable unit selection unit 322 uses only the destination floor call generated before the grace time expires. Can be assigned. For this reason, according to the present embodiment, the allocatable number machine selection unit 322 can select a number machine candidate based on whether or not the generation time of the destination floor call is within the grace period, thus simplifying the candidate selection process. Can be

  In the present embodiment, on a floor with a lot of traffic, by increasing the grace time relatively, it is possible to increase the boarding rate and improve the operation efficiency. On the other hand, in a floor with a low traffic volume, the grace time can be reduced to make it easier to answer calls on other floors. Therefore, as compared with the case where the grace time is set uniformly, in this embodiment, it is possible to prevent the time required to move to another floor from being increased, and the service quality can be improved.

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

  FIG. 7 is an explanatory diagram 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), the destination floor registration devices 20A and 20B, and the configurations of the tables T3A and T3B of the units 1A to 1N are the same as those in FIG.

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

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

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

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

  According to such setting of the grace time t1, when the walking times t5 from the plurality of destination floor registration devices 20A, 20B to the respective units 1A to 1N are different from each other, the grace time is uniformly given to all the units. Rather than setting t1, an efficient grace time can be set for each unit. For this reason, in a present Example, it can prevent that the time required for the movement to another floor for every number machine becomes uselessly long, and can operate more efficiently.

  In addition, this invention is not limited to the Example mentioned above, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.

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

  Further, for example, the door opening time limit may be controlled not only at the time of going to work or leaving work, but also at the end of an event such as lunch or a seminar. By setting the grace time longer at the crowded platform in the crowded time zone or extending the door opening time in consideration of walking time, the boarding rate can be increased and the operation efficiency can be enhanced. Furthermore, since passenger delays can be prevented, service quality can be maintained.

  Furthermore, among the multiple floors, the most congested floor is set to the maximum door opening time limit, and other floors are set with a grace period t1 according to the number of users, or considering the walking time t5. And may be extended.

  Further, in the present embodiment, the destination floor registration device 20 has been described. However, 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 card. In the case of this configuration, when entering from a plurality of banks to the bank where the group management is carrying out the operation management, it becomes possible to prevent the user from getting behind.
