  In Patent Literature 1, when a passenger calculates a walking time from a registration device for registering a destination floor to arrive at a landing, and determines that the walking time is longer than an estimated arrival time at which a car arrives at the landing, the door opening time is limited. To extend.

  In Patent Literature 2, a destination is determined based on an estimated arrival time until a user arrives at a landing from a destination floor registration device, an estimated arrival time of a car, and information on whether or not to permit waiting for a car to be opened. It is determined whether a floor call can be assigned, and a destination floor call is assigned to one of the cars that can be assigned.

JP 2013-23377 A JP 2013-119455 A

  In the prior art, for a destination call generated before a user (passenger) arrives at a landing, a car is considered in consideration of a time until the user arrives at the landing and a time at which the car arrives at the landing. Assign. Therefore, it is possible to prevent the user from falling behind the car assigned to the destination floor call.

  However, if the waiting time for opening the car is increased in anticipation of the time until the passenger arrives at the landing, the convenience of the user who has registered the destination floor in the destination floor registration device increases, but the departure of the car is delayed. . Therefore, the operation efficiency of the entire elevator group is reduced, and the service quality for the entire user may be reduced.

  The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an elevator group management system and an elevator group management system that enable both improvement in service quality provided to a user and improvement in operation efficiency of the elevator group. It is to provide a group management method.

In order to solve the above problems, an elevator group management system according to the present invention, a plurality of cars that runs on multiple floors beds, provided at least one in at least one predetermined floor among the plurality of floors, and destination floor registration device which a user registers a destination floor before boarding, a elevator group control system comprising a group management apparatus, a managing the plurality of car and the destination floor registration device, the group management apparatus , wherein the plurality of the destination call floor car count is started after arrival at the predetermined floor occurs at the predetermined floor contained in a basket in a possible time registered in the car has arrived at the predetermined floor A registration grace time setting unit for setting a certain registration grace time, and a destination floor call from among cars before arriving at the predetermined floor and before ending the registration grace time after arriving at the predetermined floor. Assignment Determine the basket, and a destination floor call assignment processor allocates the destination floor call to the allocated car.

  According to the present invention, only the destination floor call generated within the registration grace time is allocated to the car, and the destination floor call after the registration grace time is not allocated 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 even after the registration grace time has passed, and the departure of the car is delayed. As a result, service quality and operation efficiency can be improved.

It is a time chart which shows the relationship between registration grace time, walking time, a door opening time, and a maximum door opening time. It is explanatory drawing which concerns on 2nd Example and shows the relationship between a walking time, a registration grace 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 a unit control for controlling each of the units 1 (A) to 1 (N). The system includes a device 15 and a group management device 3 that determines a car that can be boarded for a destination floor call acquired by the destination floor registration system 2. 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. Then, the group management device 3 outputs a predetermined command related 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 is assigned. As a result, in this embodiment, only the destination floor call within the registration grace time is permitted, so that the departure of the car is not delayed, and it is possible to achieve both the operation efficiency and the service quality improvement of the plurality of cars as a whole. it can.

  According to this embodiment, only the destination floor call generated within the registration delay 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, a new destination floor call generated within the registration grace time can be allocated to the car (car) assigned to the destination floor call, so that the number of passengers can be increased. It is possible to suppress the delay of the departure.

  The first embodiment will be described with reference to FIGS. FIG. 1 shows an overall configuration of an elevator group management system according to the present embodiment. The elevator group management system includes a plurality of elevator units 1 (A) to 1 (N), a unit control device 15 for controlling each of the units 1 (A) to 1 (N), a destination floor registration system 2, and a group. And a management device 3. Hereinafter, the elevator machine is abbreviated as “machine”. If the car 1 (A) to 1 (N) is not particularly distinguished, it is called car 1.

  Unit 1 transports users by moving up and down between a plurality of floors. In the following, floors may be abbreviated as floors. The machine 1 includes, for example, a car 10, a hoisting machine 12 that hoists 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 in accordance with the movement of the main rope 13. And

  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 opens, and the landing operation opens the landing door 41 (see FIG. 5). After arriving at the landing 4, the car 10 waits with the door 11 opened for a predetermined time. Standing by the car 10 at the landing 4 with the door 11 opened is called door-open standby. The car 10 closes the door 11 when the occupant (passenger) operates the door close button (not shown) of the operation device in the car 10 or when the maximum door open time has elapsed. The landing door 41 is also closed by the closing operation. When the car 10 is closed, the car 10 leaves the hall 4 and moves to the floor designated by the destination floor call. The opening and closing and movement of the car 10 are handled by the car control device 15. The car control device 15 controls a door open state of the car 10 and the like according 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 desired by the user to the group management device 3 before the user arrives at the platform 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, for example, a device installed near a corridor of a building, near an entrance of a building, near a landing 4, and the like. Hereinafter, it may be abbreviated as destination floor registration device 20. 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 includes, for example, numeric keys. The display device 201 is a device that displays a value input from the input device 200 and displays a car assigned to the input destination floor. The display device 201 includes, for example, a liquid crystal display, an organic EL (Organic Light-Emitting Diode) display, and the like. The special button 202 is a button for inputting special circumstances such as, for example, a case with a small child, a user with a wheelchair, a case with a sick person, and a case with heavy luggage. The user can also input the expected number of passengers 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 examples. For example, the display device 201, the input device 200, and the special button 202 may be integrally configured as a touch panel. As the input device 200, a voice input device may be used.

  Return 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 to transmit information from the group management device 3 to 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 to the destination floor registration device 20 information on the car 1 to which the destination floor call is 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 is responsible for 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 device 3, or may be considered as a system independent of any of the group management device 3 and the destination floor registration system 2.

  A tag or terminal 23 can 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 personal digital assistant, and a tablet PC.

  For example, in the case of an IC tag or IC card type employee ID card, the destination floor reading section 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 sets 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 a destination floor via a mobile phone or a portable information terminal.

  The group management device 3 is a computer device that manages each unit 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 of the above-described hardware and software will be described. The group management device 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 device.

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

  The operation management control unit 32 assigns the car 1 to the destination floor call, and manages the door open time of each car 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 delay time setting unit 320 and a walking time setting unit 321. The registration grace time setting unit 320 has a function of setting a registration grace time for each floor or for each period. Here, the registration grace time is a time during which a destination floor call can be registered. The registration grace time starts when the car 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 car 1A arrives at the floor where the destination floor call has occurred at a certain time T0, the registration delay time t1 starts from the time T0. At the time T1 (= T0 + t1) when the registration grace time t1 expires, the destination floor call is not assigned to the car whose registration grace time t1 has expired.

  In other words, the registration grace time setting unit 320 sets a grace time for determining to what point in time a destination floor call is to be registered for a car candidate that has been made assignable without being excluded by the assignable car selection unit 322. I do.

  Return to FIG. The walking time setting section 321 sets a walking time. The walking time as an example of the “time required for movement” 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 between each destination 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 lower than the standard walking speed in case that the walking speed is lower than the standard walking speed, such as in a case of traveling with small children or having 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 has a function of assigning a destination floor call to any one of the car 1s. The destination floor call assignment processing unit P2 includes, for example, an assignable unit selection unit 322 and a destination floor registration processing unit 323.

The assignable unit selection unit 322 selects at least one of the units 1 to which a destination floor call can be assigned. The assignable car selection unit 322 extracts an assignable car candidate based on at least one preset exclusion condition as described later with reference to FIG. Specifically, for each of a plurality of exclusion conditions set in advance, a car that is inappropriate for the assignment of the destination floor call is determined and removed from car cars that can be assigned. As described below with reference to FIG. 2, the exclusion condition may be, for example, whether the departure time is in preparation after the registration grace time (S3), it is predicted that the vehicle will be full (S5), or the user will not be in time for the landing. (S7).
The car 1 corresponding to one of the exclusion conditions is excluded from car candidates that can be assigned a destination floor call. Only a car that clears all exclusion conditions is selected as a car candidate to which a destination floor call can be assigned.

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

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

  The time limit management processing unit 324 manages elements related to time management such as a registration delay time, a walking time, and a door opening time limit. The door opening command processing unit 325 sends a command for applying the door opening time limit used for the car 1 to which the destination floor call is assigned to the car 1 to the car controller 15.

  The command unit P3 transmits information specifying the car 1 to which the destination floor call has been assigned to the destination floor registration device 20 for guidance (S10), as shown in FIG. The planned stop floor of the car 1 may be displayed (S11).

  The functional configuration of the group management device 3 is not limited to the example illustrated 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 role assignment of each function 30, 31, 32 is not limited to the above example. In short, the registration grace time can be set for each floor or for each car (for each hall door), and the destination floor generated between the time when the car 1 arrives at the hall 4 and the time when the registration grace time elapses can be set. Any configuration may be used as long as the call can be assigned to any one of the cars 1.

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

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

  After grasping the status of each car based on each car data received in step S1, the group management device 3 determines whether or not the destination floor call has been registered by the landing destination floor registration device 20 via the input / output control system 22. (S2). If the destination floor call has not been registered (S2: NO), there is no need to assign the car 1 and the process proceeds to step S10.

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

  The assignable unit selection unit 322 excludes those that do not satisfy the conditions as the assigned unit candidates (S3 to S8). In this embodiment, three exclusion conditions are provided. The present invention is not limited to this, and four or more exclusion conditions may be set.

  The assignable unit selection unit 322 determines whether there is any unit 1 that is ready for departure after expiring the registration grace time t1 set by the registration grace time setting unit 320 for all the units 1 (see FIG. 4). S3). In this embodiment, the destination floor call is not assigned to the car 1 whose registration grace time has passed. This is to prevent a delay in departure.

  When it is determined that the registration grace time has expired and the departure preparation machine 1 is present (S3: YES), the allocatable car selection unit 322 excludes the car 1 from the car floor candidates to be assigned to the destination floor call (S4). On the other hand, when the assignable car selection unit 322 determines that there is no car 1 that satisfies the exclusion condition of step 3 (S3: NO), it skips step 4 and proceeds to step S5.

  The assignable unit selection unit 322 determines whether there is a unit that is expected to be full for all the units 1 that have not been excluded from the assigned unit 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 (the number of passengers) in the car based on the load signal detected by the load sensor. Alternatively, the group management device 3 can detect a user who gets 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 input per person as one and detect the number of people to be boarded. The number of users may be input. The group management device 3 can predict whether or not the car 10 of the car 1 will be full based on the detected average number of passengers based on the average weight of the user.

  When it is determined that there is a car 1 in which the car 10 becomes full when one or a plurality of users who have registered the destination floor call are boarded (S5: YES), the assignable car selection unit 322 may be full. Is excluded from the assigned car candidates (S6). On the other hand, when it is not predicted that the full state will be reached (S5: NO), the assignable number selecting unit 322 skips step S6 and proceeds to step S7.

  The assignable number selecting unit 322 targets the walk required for the user who has registered the destination floor call in the destination floor registration device 20 to reach the landing door 41 with respect to all the numbers 1 not excluded from the allocation number candidate. The time t5 is compared with a total value of an estimated arrival time required for the car 1 to be determined to arrive at the floor where the destination floor call is registered and a preset maximum door opening time t4 (walking time> (Estimated arrival time + maximum door open time)). The assignable machine selection unit 322 can use the walking time set by the walking time setting unit 321 when making the determination in step S7.

  When it is determined that the walking time is longer than the sum of the scheduled arrival time of the car 1 and the maximum door opening time (S7: YES), the assignable car selecting unit 322 excludes the car from the candidate car to be assigned (S8). ). In this case, it takes a long time (> scheduled arrival time + maximum door opening time) for the user who has registered the destination floor call to reach the landing door 41, and the departure is delayed, and other users who have already boarded are called. This is because the service quality for the service deteriorates. On the other hand, when the assignable number selecting unit 322 determines that the walking time of the user who registered the destination floor call is equal to or less than the sum of the scheduled arrival time of the number 1 and the maximum door opening time (S7: NO), It skips step S8 and moves to step S9.

  Upon receiving the information on the candidate car number extracted by the assignable car number selection section 322, the destination floor registration processing section 323 selects one of the most suitable car numbers to which the destination floor call is to be assigned from among the car number candidate (S9). . The destination floor registration processing unit 323 selects one car based on, for example, a car that arrives at the floor where the destination call occurs at the fastest time or a car that has the smallest total load.

  Further, the destination floor registration processing unit 323 causes the time management processing unit 324 to provide the door opening instruction processing unit 325 with the door opening time limit information used for determining the assigned car in step S7. The door opening instruction processing unit 325 gives an instruction to the car controller 1 of the car to which the destination floor call is assigned so as to execute the door opening time corresponding to the exclusion condition in step S7.

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

  At the scheduled stop floor platform 4 in step S11, the scheduled stop floor of each car 1 can be displayed. For example, the group management device 3 can display the planned stop floor of each car 1 using a display installed at the landing 4 or an indicator light installed near the landing door 41. The user arriving at the landing 4 checks the stop floor of the car 1 notified in step S10, and waits 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 delay time setting table T1 manages, for example, a floor column C10, a number of users column C11, and a delay time column C12 in association with each other. In the present 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 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 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 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 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 delay time setting table T1 can be updated according to the time zone. The table T1 shown in FIG. 3 shows, for example, a grace time at the time of going to work.

  At a certain point in time shown in FIG. 3 (for example, morning work time), the number of users on the first floor is the largest, "250", and the quotient divided by the threshold "50" is "5". Therefore, the grace time of 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 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”, the quotient divided by the threshold “50” is “1”. Therefore, the grace time for the third floor is set to “1 second”. Since the number of users on the fifth floor is “50”, the quotient divided by the threshold “50” is “1”. Therefore, 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 when the car 1 arrives at the landing 4 as a starting point. For example, on the first floor, counting starts when the car arrives at the landing, and the grace period expires after 5 seconds. If the user registers a destination floor call before the expiration of the grace time t1, the destination floor call can be assigned to the car, and the user can board the car. On the other hand, for a destination floor call registered by the user after the expiration of the grace time t1, the destination floor call is not assigned to the car, so the user cannot get on the car.

  If the grace time t1 is set to a large value, the time required for the car 1 to depart from the floor increases. Therefore, in the present embodiment, on a floor with a small traffic volume, the value of the grace time t1 is set to a small value so that it is easy to respond to calls on other floors. On the other hand, on a floor with a large traffic volume, the value of the grace time t1 is set relatively large, so that passengers can easily get into the car 10 and the occupancy rate is increased. Accordingly, in this embodiment, the waiting time in the door-open standby state is shortened on the floor where the number of users is small, and the departure of the car 1 is accelerated. The rate can be improved. As a result, in this embodiment, both the service quality and the transportation efficiency (operation efficiency) can be improved.

  The threshold for the number of users may be a fixed value or may be changed according to the operation status. The threshold for the number of users 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 (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 grace time setting table T1 may be updated every time the operation status learning result is updated, or may be updated at a predetermined time. The grace time may be adjusted in consideration of a day of the week or a holiday. Further, 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 a 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 walking time is considered, and a maximum door opening time column C23. FIG. 4 shows the time limit for opening the doors of the first floor unit 1, and omits illustration of the other floors and the door opening time periods of other units. It is to be noted that since different cases surely occur in each unit only in the door opening time column C22 when the walking time is considered, 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 the walking time is taken into consideration may be separately managed, and a table common to each car may be used.

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

  The door opening time limit column C22 when the walking time is considered is a door opening time t3 that takes into account the time required for the user who has registered the destination floor call to move from the destination floor registration device 20 to the landing door 41 of the predetermined car 1. This is a column to be managed. The door opening time t3 in consideration of the walking time is updated every time the door opening time is extended in consideration of the walking time t5, by assigning a destination floor call to the car until the grace time t1 elapses. As the value of the door opening time t3 when the walking time is considered, the normal door opening time t2 is set as an initial value, and the maximum door opening time t4 is changed as the maximum value. The maximum door opening time period column C23 is a column for managing the upper limit value t4 of the time that the car 1 arriving at the landing 4 can stand by with the door 11 opened. 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 delay time t1, the normal door-opening time t2, the door-opening time t3 in consideration of the walking time, and the maximum door-opening time t4 are set to be longer 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 time 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 use 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 among the walking time, the registration delay time, and the door opening time limit. Here, a plurality of car units 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 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 distances between the landing 4 (1) and the destination floor registration devices 20A and 20B, or may be generally defined as the distances that the user follows.

  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 from each other. Here, it is assumed that the landing doors 41 (1A), 41 (1B), 41 (1C), and 41 (1N) are closer to the destination floor registration devices 20A and 20B in this order.

  Above each of the units 1A to 1N, time limit management tables T3A and T3B for each of the destination floor registration devices 20A and 20B are shown. One time limit 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 cars 1A to 1N, and a time period t5 required for each of the cars 1A to 1N. The relationship between the grace time t1 and the maximum door open time 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 each of the cars 1A to 1N, The relationship between the grace time t1 and the maximum door open time t4 in each of the units 1A to 1N is shown.

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

  Attention is paid to 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. If 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). On this floor (first floor), the grace time t1 for registering the destination floor call in the destination floor registration device 20A is set to 3 seconds. When the car 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 time t1 is set to 3 seconds, so the maximum door opening time 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). Therefore, the maximum door opening time t4 in this case is 12 seconds (9 + 3 = 12). When the car 1N is assigned to the destination floor call, since the walking time t5 is 10 seconds and the grace time t1 is 3 seconds, the maximum door opening time t4 is 13 seconds (10 + 3 = 13).

  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 destination floor call is assigned to the car 1A, the walking time t5 is 10 seconds and the grace time t1 is 3 seconds, so the maximum door opening time is 13 seconds. When the destination floor call is assigned to the car 1B, the maximum door opening time t4 is 14 seconds because the walking time t5 is 11 seconds and the grace time t1 is 3 seconds. When the destination floor call is assigned to the car 1C, the maximum door-open time t4 is 15 seconds because the walking time t5 is 12 seconds and the grace time t1 is 3 seconds. When the destination floor call is assigned to the car 1N, the maximum door opening time t4 is 16 seconds because the walking time t5 is 13 seconds and the grace time t1 is 3 seconds.

  The walking time t5 may be set as a fixed value based on 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 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 value of the walking time, or the learning result of the daily use situation may be reflected in the walking time.

  Further, in FIG. 5, the grace period t1 is set to a common value for each of the units 1, but may be set to different values. Further, the grace period t1 may be different for each destination floor registration device. If the destination floor registration device is close to the car, even if the destination floor is registered after arriving at each car, the user can get on in a short time, and within the normal door opening time limit t2 and the maximum door opening time limit t4. This is because the expected value of being able to ride on is high.

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

  The time T1 is a 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 t2 has elapsed from the arrival time T0 of the car. The time T3 is a time when the walking time t5 has elapsed from the arrival time T0 of the car, that is, a time when the door opening time t3 when the walking time is considered has elapsed from the time T0. The time T4 is a time when the maximum door opening time t4 has elapsed from the arrival time T0 of the car.

  FIG. 6 shows a case where the users 5A to 5E board the car 1A that has arrived at the landing floor at time T0. The position of each of the users 5A to 5E in FIG. 6 indicates the time when the destination floor call is registered in the destination floor registration device 20 (when the destination floor call occurs). The physical location of each user at the time of occurrence of the destination floor call is the location where the destination floor registration device 20 is installed. Here, each of the users 5A to 5E is merely arranged for the description of the context of the grace period t1, and is actually registered in the destination floor registration device at a different timing without being continuous. Shall be.

  The user 5A who has 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 car 1A is located corresponding to the arrival time of the car 1A. The user 5C who has registered the destination floor before the grace time t1 has elapsed after the arrival of the car 1A is located on the right side of the car 1A and before the expiration of the grace time t1. The user 5D who has registered the destination floor after the elapse of the grace time t1 of the car 1A is located on the right side of the car 1A at a time after the grace time t1. Although the user 5E has registered the destination floor before the arrival of the car 1A, the user 5E has arrived at the landing 4 (1) after the elapse of the maximum door opening time t4 of the car 1A due to the slow moving speed.

  The user 5A can get into the car 1A by the time T2 when the normal door opening time t2 of the car 1A expires, even if the walking time is taken into consideration. Specifically, assuming that the time from the registration to the arrival of the car 1A is t6, there is a time for walking to the car from the registration to the arrival of the car. In this case, t6 is subtracted from the walking time t5, and t2> t5−t6, so that the user 5A can get on the car 1A by the time T2 when the normal door opening time t2 expires. Therefore, in the case of the user 5A, the door is closed at time T2 when the normal door opening time t2 has elapsed from the arrival time T0 of the car.

  The user 5B registers a 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 car 1A is 0. In this case, since the normal door opening time t2 <the walking time t5-t6 (= 0), the user 5B cannot board the car 1A by the expiration time T2 of the normal door opening time t2. However, if the door opening time is extended from the normal door opening time t2 to the door opening time t3 when the walking time is taken into account, the user 5B must wait until the time T3 when the door opening time t3 when taking the walking time into consideration expires. Close the door at time T3 because you can get on 1A

  The user 5C registers a destination floor call after the car 1A arrives at the landing. Since the destination floor call occurs within the registration delay time t1, the destination floor call can be registered in the car 1A. However, considering the walking time t5, the user 5C cannot get into the car within the normal door opening time t2. More 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, so that t2 <t5-(-t6) and t2. Will be exceeded. Here, even if the door opening time t3 in consideration of 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 t4 expires. Conversely, if the above condition is not satisfied and (t5-(-t6)) exceeds t4, 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 reduced, and at the same time, other users already in the car are uncomfortable.

  Since the user 5D has registered the destination floor call after the grace time t1, considering the walking time t5, the user 5D cannot get into the car 1A by the time T4 when the maximum door opening time t4 expires. Therefore, the car 1A is not assigned to the destination floor call after the expiration time T1 of the grace time t1.

  The user 5E has registered the destination floor call before the arrival of the car 1A, and the car 1A has been assigned to this destination call by the same calculation as in the above 5A. However, in some cases, such as when the walking speed is low or when the user stops at another place, it may not be possible to get into the car 1A by the time T4 when the maximum door opening time t4 expires. In this case, the car 1A closes the door at time T4 and starts. The destination floor call of the user 5E is assigned to the next car. When the assigned machine is changed, the change of the assigned machine may be notified to the user 5E from a display or the like installed at the landing. Here, the confirmation that the user 5E is not in the car 1A is performed by detecting that the weight is insufficient by the weight sensor of the car 1A or by using a radio sensor to assign the user to the car in the car. By comparing the persons, it is possible to detect that 5E is not in the car 1A.

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

  In the present embodiment, even a user who could not get on until now because of a low walking speed can extend the door opening time in consideration of the walking time, and thus can get on. Therefore, in this embodiment, the possibility of the user getting on the vehicle can be increased, and the service quality can be improved. Furthermore, since the boarding rate can be increased, the operation efficiency can be improved.

  Furthermore, in this embodiment, registration of the destination floor call is not permitted after the grace period has elapsed, so that the door opening time is not unnecessarily extended. For this reason, the service quality can be improved by suppressing the delay of the departure, and the wasteful waiting time can be reduced to improve the transportation efficiency.

  Since the operation management control unit 32 of the present embodiment includes the walking time setting unit 321 and the registration grace time setting unit 320, it is possible to provide an efficient service according to the use situation. As described above, at a crowded landing in a crowded time zone, the occupancy rate can be increased by setting a longer grace time or extending the door opening time limit in consideration of the walking time. Alternatively, on a congested floor in a congested time zone, the door opening time of all or at least some of the cars can be extended to the maximum door opening time.

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

  In the present embodiment, on a floor with a large traffic volume, by increasing the grace time relatively, the occupancy rate can be increased and the operation efficiency can be improved. On the other hand, on a floor with a small traffic volume, the grace time can be reduced to facilitate answering calls on other floors. Therefore, compared to the case where the grace time is set uniformly, in the present embodiment, it is possible to prevent the time required for moving to another floor from becoming longer, and to improve the service quality.

  A second embodiment will be described with reference to FIG. This embodiment corresponds to a modified example of the first embodiment, and therefore, the description will focus on differences from the first embodiment. In this embodiment, a value obtained by subtracting the walking time t5 from the maximum door opening time limit t4 is set as the grace time t1.

  FIG. 7 is an explanatory diagram showing the relationship among the walking time, the registration delay time, and the door opening time limit. The relationship between the landing doors 41 (1A) to 41 (1N) of each of the cars 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 time t1 is set for each floor in each of 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 grace 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 grace time t1 of 3 seconds is set for all the units 1A to 1N on the first floor.

  On the other hand, in the present embodiment, the grace time t1 by the registration grace time setting unit 320 is set for each car. 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 Grace time t1 is 5 seconds.

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

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

  Note that the present invention is not limited to the above-described embodiment, and includes various modifications. For example, the above-described embodiments have been 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 above.

  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, the operation management control unit 32 may perform the control only at a predetermined congestion such as when using the restaurant floor at the time of going in and out of work or at the time of lunch. Alternatively, in a non-congested time zone, the grace time t1 on the first, third, and fifth floors shown in FIG. 3 may be set to 0 second.

  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 time of the end of an event such as lunch or a seminar. At a crowded landing in a crowded time zone, by setting a longer grace time or extending a door opening time limit in consideration of a walking time, the occupancy rate can be increased and the operating efficiency can be increased. Furthermore, since the passengers can be prevented from being late, service quality can be maintained.

  Further, among the plurality of floors, the door opening time is set to the maximum door opening time on the most crowded floor, and on other floors, the grace time t1 is set according to the number of users, and the walking time t5 is considered. The configuration may be extended.

  Further, in this embodiment, the destination floor registration device 20 has been described. However, a 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, it is possible to prevent a user from getting on and off when entering from a plurality of banks to a bank in which the group management performs operation management.
