<Overview of Elevator Management System 100>
An embodiment of the present invention will be described in detail below. FIG. 1 is a functional block diagram showing an example of the configuration of an elevator management system 100 according to this embodiment. The elevator management system 100 is a system for managing elevators 5 provided in a building having multiple floors. The elevator management system 100 allocates an optimum car number to the target of use of the elevator 5 having a hall destination floor registration function (for example, a user or the information processing device 2) in response to a destination floor call. In addition, the elevator management system 100 moves the elevator assigned to the use target to the departure floor and destination floor specified by the destination floor call.

Here, the "platform destination floor registration function" is to allocate the optimum car according to the departure floor and destination floor of the use target, and guide the use target to the assigned car as the car that the use target will board. It is a function that can effectively shorten the time the object waits for the arrival of the elevator. Also, the destination floor registration function can shorten the time required for the object to be used to arrive at the destination floor. The "elevator number assigned to the destination floor call" is intended to be the elevator number of the elevator 5 determined by the assignment control device 1 as the assigned elevator number to be used by the user who made the destination floor call. A case where the elevator 5 has a plurality of elevators will be described below as an example. FIG. 1 illustrates an elevator 5 having a plurality of elevators. For example, elevators 5A to 5C are elevators 1 to 3, respectively.

"Destination floor call" is a process of registering allocation request data including a departure floor and a destination floor in the allocation control device 1 in advance. When the target of use is a user, the destination floor call is, for example, performed by the user inputting the desired destination floor or the like into the landing destination floor registration device 3 installed on the departure floor. The hall destination floor registration device 3 may perform the processing. When the operation is performed, the landing destination floor registration device 3 registers information including the information indicating the input destination floor and the information of the floor where the landing destination floor registration device 3 is installed, and the landing destination floor. and identification information indicating the registration device 3 may be transmitted to the allocation control device 1 . The user uses a mobile terminal such as a smartphone as the landing destination floor registration device 3 to send allocation request data including information indicating the departure floor and destination floor and identification information of the landing destination floor registration device 3 to the allocation control device 1. You may send. When the target of use is the information processing device 2, the destination floor call is, for example, an assignment from the information processing device 2 to the allocation control device 1 including information indicating the departure floor and the destination floor and identification information of the information processing device 2. It may be done by sending request data.

In this specification, the transmission of allocation request data by the information processing device 2 or the hall destination floor registration device 3 to the allocation control device 1 is referred to as "calling a destination floor" or "registering a destination floor call". Also, the assignment control device 1 determines the assigned elevator based on each assignment request data, and inputs the information based on the assignment data into the database showing the movement schedule of the elevator 5, which means "to complete the registration of the destination floor call". called.

The information processing device 2 in the elevator management system 100 is a device capable of autonomous travel, and can move between floors using the elevator 5 . The information processing device 2 may be an automatic transport device, a self-propelled cleaning device, or other multifunctional robots that are installed in the building in advance. Alternatively, the information processing device 2 may be a dedicated device installed in the building in accordance with the introduction of the elevator management system 100 . As shown in FIG. 1 , the elevator management system 100 may include multiple information processing devices 2 . A case where the elevator management system 100 includes two information processing devices 2 will be described below as an example. However, the number of information processing apparatuses 2 is not limited to two, and may be three or more.

Further, in this specification, a destination floor call newly received from the information processing device 2 by the allocation control device 1 and for which registration has not been completed is referred to as a "new destination floor call", and the information processing device that made the new destination floor call. 2 is called an information processing device 2A. A destination floor call that has already been registered before the new destination floor call is received by the allocation control device 1 is referred to as an "existing call", and the information processing device 2 that made the existing call is referred to as an information processing device 2B. Note that when there are three or more information processing apparatuses 2, the plurality of information processing apparatuses 2 may correspond to the information processing apparatus 2B.

FIG. 2 is a block diagram showing an example of the configuration of the allocation control device 1. As shown in FIG. The allocation control device 1 of the elevator management system 100 in this embodiment includes an elevator allocation unit 114 that allocates an elevator based on a destination floor call. When the information processing device 2A makes a call for a new destination floor, the elevator car allocation unit 114 of the allocation control device 1 controls the progress associated with getting on and off the elevator 5 between the information processing device 2A and the information processing device 2B registered with the existing call. Decide the car number to be assigned to a new destination floor call so as not to prevent a situation from occurring.

The "situation that hinders the progress of boarding and exiting the elevator 5" refers to a situation in which, when a certain information processing device 2 uses the elevator 5, the progress is hindered by another information processing device 2, and collision avoidance must be performed. show. In the following description, "situation that interferes with getting on and off the elevator 5" is also simply referred to as "interference".

For example, when a certain information processing device 2 gets on an elevator 5 and another information processing device 2 gets off from the elevator 5, one information processing device 2 is positioned on the route of the other information processing device 2, It may interfere with getting on and off. When a plurality of information processing apparatuses 2 are in such a situation, it can be expressed that there is interference between the information processing apparatuses 2, ie, a situation that interferes with getting on and off the elevator 5. FIG. The details of the "situation that hinders the progress of getting on and off the elevator 5" will be described later. The car allocation unit 114 allocates cars so as to prevent such a situation from occurring as much as possible.

As an example, when the allocation control device 1 accepts a new destination floor call and there is an existing call that has already been registered, when the allocated elevator assigned to the existing call is allocated to the new destination floor call, the new destination floor call is registered. It is determined whether the occurrence of a situation that hinders the progress of getting on and off the elevator 5 is predicted between the information processing device 2A that registered the existing call and the information processing device 2B that registered the existing call. Here, when the occurrence of the situation described above is predicted, the elevator car assignment unit 114 of the assignment control device 1 sends the assigned elevator car assigned to the existing call to the information processing device 2A that registered the new destination floor call. Assign a different machine number.

FIG. 5 is a block diagram showing an example of the configuration of the information processing device 2. As shown in FIG. A schematic configuration of the information processing device 2 will be described below with reference to FIG. Although two information processing apparatuses 2 are illustrated in FIGS. 1 and 5, there may be a plurality of information processing apparatuses 2, for example, three or more.

As shown in FIG. 5 , the information processing device 2 includes a control section 21 , a communication section 22 , a drive section 23 and a storage section 24 . The control section 21 controls the operation of each section of the information processing device 2 . The control unit 21 has a generation unit 211 and a movement control unit 212 .

The generation unit 211 registers a destination floor call from the information processing device 2 to the allocation control device 1 .

The movement control unit 212 operates the driving unit 23 based on the information indicating the allocation result, and moves the information processing device 2 to the boarding hall of the allocated car.

When the car 52 of the assigned car arrives at the departure floor of the information processing device 2 and the door 53 opens, the movement control unit 212 receives a boarding instruction to board the car 52 from the assignment control device 1 . Upon receiving the boarding instruction, the movement control section 212 operates the drive section 23 to cause the information processing device 2 to board the car 52 of the assigned elevator of the elevator 5 .

After the information processing device 2 gets on the car 52 and reaches the destination floor, the movement control unit 212 receives a get-off instruction from the assignment control device 1 to get off the car 52 . Upon receiving the exit instruction, the movement control unit 212 operates the driving unit 23 to cause the information processing device 2 to exit the car 52 of the assigned elevator of the elevator 5 .

The communication unit 22 is a communication module for wireless communication between the information processing device 2 and the allocation control device 1 . The drive unit 23 is a drive mechanism for moving the information processing device 2 and operates under the control of the movement control unit 212 . The drive 23 may be any drive mechanism such as wheels, caterpillars, and walking legs. The storage unit 24 is a storage device in which various computer programs read by the control unit 21 and data used in various processes executed by the control unit 21 are stored.

[Allocation control device 1]
Next, the assignment control device 1 will be explained. The allocation control device 1 is a device that receives a destination floor call from a user and allocates an optimum elevator car according to the destination floor call. Further, the allocation control device 1 operates the elevator 5 based on the received destination floor call and the result of allocation of the elevator to the destination floor call. When the target of use is the information processing device 2 , the allocation control device 1 instructs the information processing device 2 to get on and off the car 52 of the elevator 5 .

Furthermore, when the allocation control device 1 receives a new destination floor call from the information processing device 2A, the allocation control device 1 determines the allocated car so that interference does not occur between the information processing device 2A and the information processing device 2B in which the existing call is registered. do.

A schematic configuration of the allocation control device 1 will be described below with reference to FIG. As shown in FIG. 2 , the allocation control device 1 includes a control section 11 , an input/output interface 12 and a storage section 13 . The control unit 11 controls to execute each process in the allocation control device 1 . The control unit 11 will be described later.

The allocation control device 1 communicates with each information processing device 2 by wireless connection, and transmits and receives each information via the input/output interface 12 . Also, the allocation control device 1 communicates with each hall destination floor registration device 3 and the elevator control device 4 and transmits and receives various information via the input/output interface 12 . The connection method between the allocation control device 1 and the hall destination floor registration device 3 or the elevator control device 4 may be a wireless connection or a wired connection.

The storage unit 13 is a storage device in which various computer programs read by the control unit 11 and data used in various processes executed by the control unit 11 are stored. Furthermore, the storage unit 13 stores a landing destination floor DB 131 and an elevator DB 132 .

FIG. 6 is a diagram showing an example of the hall destination floor DB 131. As shown in FIG. The landing destination floor DB (database) 131 is a database that stores information on registered destination floor calls. As shown in FIG. 6, the boarding point destination floor DB 131 stores information indicating the attributes of the object to be used, the robot ID or user ID, the information indicating the departure floor, the information indicating the destination floor, and the information indicating the allocated elevator. , are stored in association with each registered destination floor call.

When the registered destination floor call is transmitted from the hall destination floor registration device 3, information indicating "user" is stored in the hall destination floor DB 131 as the attribute to be used. On the other hand, when the registered destination floor call is transmitted from the information processing device 2, information indicating "information processing device" is stored in the hall destination floor DB 131 as the attribute to be used.

The robot ID is identification information that can identify each information processing device 2 . Data with "-" in the robot ID column in the hall destination floor DB 131 indicates that the robot ID is not associated. For example, when the user operates the hall destination floor registration device 3 to call the destination floor, "-" is stored in the robot ID column of the hall destination floor DB 131 .

The user ID is identification information that can identify each hall destination floor registration device 3 . Data with "-" in the column of the user ID in the hall destination floor DB 131 indicates that the user ID is not associated. For example, when the information processing device 2 calls the destination floor, "-" is stored in the column of the user ID of the hall destination floor DB 131. FIG.

Information included in the allocation request data corresponding to each destination floor call received by allocation control device 1 is stored in hall destination floor DB 131 as information indicating the departure floor and destination floor. In addition, as information indicating the allocated elevator car, information indicating the assigned elevator car for each destination floor call is stored in the hall destination floor DB 131 .

FIG. 7 is a diagram showing an example of the elevator DB 132. As shown in FIG. The elevator DB (database) 132 is a database in which information about each car of the elevator 5 is associated and stored. As shown in FIG. 7, the elevator DB 132 stores the identification information (elevator ID) of the elevator 5 and the current floor, which is the floor where the car 52 is located (if the car 52 is moving, the elevator DB 132 stores the elevator ID). If the car 52 changes and the car 52 is stopped, it is the stop floor), the current direction of the car 52 (current moving direction), and the destination floor, which is the floor to which the car 52 is scheduled to move, correspond to each car number. attached.

The control unit 11 controls to execute processing of each function provided in the allocation control device 1 . In addition, the control unit 11 comprehensively manages the operation of each car. As shown in FIG. 2 , the control unit 11 includes a reception unit 111 , a determination unit 112 , a specification unit 113 , a machine number allocation unit 114 and a main control unit 115 .

(Reception unit 111)
The reception unit 111 communicates with the information processing device 2 or the hall destination floor registration device 3 via the input/output interface 12, and receives a destination floor call from a user. Specifically, the reception unit 111 receives allocation request data from the hall destination floor registration device 3 or the information processing device 2 . The allocation request data received by the reception unit 111 includes identification information of the hall destination floor registration device 3 or the information processing device 2, information indicating the departure floor, and information indicating the destination floor.

In addition, the receiving unit 111 outputs various pieces of information regarding the received destination floor call to each unit of the control unit 11 according to the attribute of the registered destination floor call. When receiving a destination floor call from the landing destination floor registration device 3 operated by the user, the reception unit 111 transmits the identification information of the landing destination floor registration device 3, the departure floor, and the information indicating the destination floor to the identification unit 113. output to Further, when receiving a destination floor call from the information processing device 2 , the reception unit 111 outputs information indicating the identification information of the information processing device 2 , the departure floor, and the destination floor to the determination unit 112 .

(Determination unit 112)
The determination unit 112 acquires information about the information processing device 2A that made the new destination floor call from the reception unit 111, and it is predicted that the information processing device 2A and the information processing device 2B in which the existing call has been registered will interfere. determine whether or not Determining portion 112 outputs the identification information of information processing device 2</b>A and the determination result to identifying portion 113 .

In a certain car number, if the car number is assigned to the information processing device 2A and either of the following (A) or (B) applies, the determination unit 112 assigns the car number to the information processing device 2A. It is determined that interference is expected to occur between the device 2A and the information processing device 2B. The situation in which interference is expected to occur is that when one of the information processing devices 2A and 2B gets on the car assigned to the information processing device 2B, the other of the information processing devices 2A and 2B can be rephrased as a situation in which the driver gets off the vehicle.

(A) In a certain car, when the information processing device 2A boards on the departure floor, another information processing device 2B is scheduled to get off.

(B) In a certain car, when the information processing device 2A gets off at the destination floor, another information processing device 2B is scheduled to board.

The determination unit 112 refers to the hall destination floor DB 131 and identifies data related to an existing call to which one of the elevators 5, for example, No. 1, is assigned. Based on the specified data and the information indicating the departure floor and destination floor included in the new destination floor call, determination unit 112 allocates the elevator car to information processing device 2A, and selects either (A) or (B) above. In other words, it is determined whether or not interference can occur between the information processing device 2A and the information processing device 2B. The determination unit 112 performs the above-described determination for all cars, and outputs the determination result for each car to the identification unit 113 .

For example, when an existing call with the first floor as the destination floor has already been registered by the information processing device 2B, and the first car is assigned to the existing call, the information processing device 2A requests that the first floor be the departure floor. When a new destination floor call for the fifth floor is received, assigning the first car to the information processing device 2A corresponds to the above situation (A). In this case, the determination unit 112 determines that interference may occur if the first device is assigned to the information processing device 2A. In addition, when an existing call with the destination floor of the 5th floor has been registered by the information processing device 2B, and the 1st car has been assigned to the existing call, the information processing device 2A requests that the 1st floor be the departure floor. When a new destination floor call for the fifth floor is accepted, and the first car is assigned to the information processing device 2A, the above situation (B) applies. In this case, the determination unit 112 determines that interference may occur if the first device is assigned to the information processing device 2A.

In addition, when a plurality of existing calls are assigned to the car to be judged, in other words, the car corresponds to the allocated car corresponding to a plurality of "information on existing calls" in the platform destination floor DB 131. If so, the determination unit 112 determines all of these existing calls. For example, when the determining unit 112 determines about the second elevator of the elevator 5, all the existing calls whose "utilization target attribute" is "robot" and whose "assigned elevator" is "2" in the platform destination floor DB 131 make a judgment. When interference may occur between the information processing device 2B and the information processing device 2A that have made at least one existing call for a given car, the determination unit 112 determines that interference will occur if the car is assigned to the information processing device 2A. It is determined that this is predicted.

(Specifying unit 113)
The identifying unit 113 identifies candidate elevators that are candidates for elevators 5 to be assigned to the use target.

When the target of use is a user, the specifying unit 113 acquires information about the destination floor call registered by the hall destination floor registration device 3 from the reception unit 111 . When acquiring the information, the identifying unit 113 sets all the elevators of the elevator 5 as candidate elevators, and outputs information indicating the candidate elevators to the elevator assigning unit 114 .

When the target of use is the information processing device 2 , the identification unit 113 acquires the determination result for each car from the determination unit 112 . Based on the result of the determination, the identification unit 113 adds, to the candidate cars, cars determined that no interference will occur between the information processing devices 2A and 2B. When the determination unit 112 completes the determination for all cars, the specification unit 113 outputs information indicating the cars added to the candidate cars to the car allocation unit 114 .

When there are a plurality of existing calls assigned to the car to be determined, the determining unit 112 performs Determine whether or not interference will occur. The specifying unit 113 acquires those determination results. When interference may occur between at least one information processing device 2B and the information processing device 2A, the identification unit 113 excludes the car that is the determination target from the candidate cars.

(Number assigning unit 114)
The elevator car allocation unit 114 acquires information indicating candidate elevator cars from the identifying unit 113 . The elevator car assigning unit 114 determines an assigned elevator car from among the candidate elevator cars, and determines it as the assigned elevator car to be assigned to the user who made the call. As a method for the elevator car assignment unit 114 to determine the assigned elevator car from among the candidate elevator cars, a method conventionally used in a system having a platform destination floor registration function may be used.

Here, from among the candidate cars that are candidates for the allocation car to be allocated to the information processing device 2A by the car allocation unit 114, the car is expected to cause interference between the information processing device 2A and the information processing device 2B. are excluded. As a result, the elevator car allocation unit 114 can allocate elevator cars so as to reduce the occurrence of a situation in which one of the information processing devices 2A and 2B using the elevator 5 hinders the progress of the other.

After determining the allocated car, the car number allocation unit 114 stores data on the new destination floor in the hall destination floor DB 131 . In addition, the elevator number assigning unit 114 adds a destination floor based on the new destination floor call to the destination floors of the assigned elevator elevator in the elevator DB 132 . The elevator car allocation unit 114 identifies the use target for which the new destination floor call is registered based on the identification information included in the allocation request data, and transmits the allocation result to the transmission source of the new destination floor call. The allocation result includes information indicating that the registration of the destination floor call has been completed and information indicating the assigned elevator car. Registration of the new destination floor call is completed as described above.

(Main control unit 115)
The main control unit 115 performs other processes in the elevator management system 100. FIG. For example, the main control unit 115 determines the operation of the elevator 5 based on the elevator DB 132 and issues an instruction to the elevator control device 4 that controls the elevator 5 . Further, the main control unit 115 instructs the information processing device 2 in which the destination floor call has been registered to get on and off the car 52 of the assigned elevator based on the hall destination floor DB 131 and the elevator DB 132 .

The main control unit 115 determines the destination floor of the car 52 provided for each car of the elevator 5 based on the elevator DB 132, and transmits an instruction to the elevator control device 4 corresponding to each car. Further, when the car 52 of the elevator 5 arrives at any floor, the main control unit 115 receives information indicating that the car 52 has arrived at the floor from the elevator control device 4, and performs various controls based on the information. . For example, when the main control unit 115 receives information indicating that the car 52 has arrived at the instructed floor, the main control unit 115 opens the door 53, and after a predetermined time or when an operation instructing the closing of the door 53 is received, the door 53 opens. A signal is sent to the elevator controller 4 instructing the closing of the . After that, the elevator controller 4 is instructed to move the car 52 to the next destination floor.

Further, when information indicating that a certain elevator has arrived at the instructed floor is received from the elevator control device 4, the main control unit 115 stores the destination floor to which the car 52 has arrived, among the destination floors of the elevator in the elevator DB 132. Delete the information indicating

Further, when the car 52 of the elevator 5 arrives at any floor, the main control unit 115 refers to the landing destination floor DB 131, and if the floor corresponds to the departure floor or destination floor of the information processing device 2, The information processing device 2 is instructed to get on and off the car 52 .

Specifically, when the floor on which the car 52 of the elevator 5 arrives corresponds to the departure floor of the information processing device 2, the main control unit 115 issues a boarding instruction to instruct the information processing device 2 to board the car 52. Send a signal. Upon receiving boarding completion information indicating that boarding of the car 52 has been completed from the information processing device 2, the main control unit 115 closes the door 53 of the car 52 in which the information processing device 2 has boarded, and moves the car 52 to the next position. to the elevator control device 4 corresponding to the car 52, instructing the car to move to the second floor.

When the floor where the car 52 of the elevator 5 arrives corresponds to the destination floor of the information processing device 2 , the main control unit 115 transmits a get-off instruction to the information processing device 2 to get off the car 52 . When the information processing device 2 gets off, the information on the destination floor call registered by the information processing device 2 is deleted from the platform destination floor DB 131 . As a result, the hall destination floor DB 131 always stores only information about destination floor calls for which correspondence has not been completed.

<Effects of allocation control device 1>
In the allocation control device 1 according to the present embodiment, the reception unit 111 receives a destination floor call from the information processing device 2, and the car allocation unit 114 determines the allocated car to be allocated to the information processing device 2 according to the destination floor call. do.

Here, when the determination unit 112 of the allocation control device 1 receives a new destination floor call from the information processing device 2A, it allocates to the information processing device 2A the same car number as the information processing device 2B. and the information processing device 2B, it is determined whether a situation that hinders the progress of getting on and off the elevator 5 is predicted.

In addition, when the elevator number assigning unit 114 assigns the assigned elevator assigned to the existing call to the new destination floor call, a situation occurs between the information processing device 2A and the information processing device 2B that hinders the progress of getting on and off the elevator 5. is predicted, the information processing device 2A is assigned a different number from the assigned number assigned to the information processing device 2B.

In a conventional device having a hall destination floor registration function, allocation is generally performed so as to reduce the number of car stops and travel distances and improve transportation efficiency. However, in the example shown in FIG. 8, if the first car assigned to the information processing device 2B that registered the existing call is also assigned to the information processing device 2A that registered the new destination floor call, the 5th floor , when the information processing device 2A gets on the car 52, the information processing device 2B gets off the car 52. FIG. In such a case, the information processing device 2A and the information processing device 2B may need to avoid collision. In such a case, one of information processing device 2A and information processing device 2B is located on the path of the other and interferes with the other's boarding/alighting operation. One may need to take evasive action. If at least one of the information processing devices 2 performs an avoidance action, it may take time to get in and out of each information processing device 2, or it may interfere with other users. Furthermore, in the above-described case, a so-called deadlock state occurs in which both information processing apparatuses 2 are unable to move when each information processing apparatus 2 tries to perform an avoidance operation, and there is a possibility that the deadlock state cannot be escaped from.

On the other hand, in the assignment control device 1 according to the present invention, the assigned car is determined by the car assigning unit 114 so as to reduce the possibility of occurrence of interference, as described above. Here, the car allocation unit 114 prioritizes the possibility of interference over the number of times the car 52 stops and the distance traveled, and allocates a car that is unlikely to cause interference even if the number of times the car 52 stops increases. Decide as the machine number. As a result, the allocation control device 1 reduces the occurrence of a situation in which one of the information processing devices 2 using the elevator 5 hinders the progress of the other, and reduces the occurrence of a deadlock state in which each information processing device 2 cannot move. becomes possible.

Further, the "situation that hinders the progress of boarding and exiting the elevator 5 between the information processing device 2A and the information processing device 2B" means, for example, that the information processing device 2A and the information processing device When one of the devices 2B gets on, the other of the information processing devices 2A and 2B gets off.

Further, when it is predicted that the situation described above may occur if a machine different from information processing device 2B is allocated to information processing device 2A, machine number allocation unit 114 does not send information to information processing device 2A. A machine number different from that of the processing device 2B is assigned.

When another information processing device 2 gets on at a floor where the information processing device 2 gets off in a certain car, there is a high possibility that one of the information processing devices 2 hinders the progress of the other. Therefore, in such a situation, a situation may occur in which both information processing apparatuses 2 cannot move.

Here, according to the above configuration, the information processing device 2A that has registered the new destination floor call is not assigned a car that may cause the situation described above. Therefore, it is possible to reduce the possibility that one of the information processing devices 2 using the elevator 5 will hinder the progress of the other.

<Example of Flow of Processing Performed by Assignment Control Device 1>
FIG. 13 is a flowchart showing an example of the flow of processing (allocation method) performed by the allocation control device 1. As shown in FIG. An example of the flow of processing (allocation control method) performed by the allocation control device 1 will be described below with reference to FIG. 13 .

The reception unit 111 waits for processing until allocation request data is received from the information processing device 2 or the hall destination floor registration device 3 (until YES in S1). When receiving allocation request data from the information processing device 2 or the hall destination floor registration device 3, in other words, when receiving a new destination floor call (YES in S1), the reception unit 111 identifies the attribute (user type) to be used. . The allocation request data includes information indicating the identification information of the utilization target, the departure floor, and the destination floor.

When the allocation request data includes the identification information of the hall destination floor registration device 3, the attribute to be used is the user. If the attribute to be used is the user, in other words, if the attribute to be used is not the information processing device 2 (NO in S2), the reception unit 111 receives the identification information of the platform destination floor registration device 3, the departure floor, the destination The floor is output to the identification unit 113 . When the identifying unit 113 acquires these pieces of information, the identifying unit 113 identifies all elevators 5 as candidate elevators (S3), information indicating the identified candidate elevators, and identification information of the hall destination floor registration device 3. , the departure floor and the destination floor are output to the elevator car assignment unit 114 .

On the other hand, when the allocation request data includes the identification information of the information processing device 2 , the attribute to be used is the information processing device 2 . When the attribute to be used is the information processing device 2 (YES in S2), in other words, when a new destination floor call is received from the information processing device 2A, the reception unit 111 outputs allocation request data to the determination unit 112. do.

When the assignment request data is acquired from the reception unit 111, the determination unit 112 starts determining whether or not interference is expected to occur when the elevator 5 is assigned to a certain car. Hereinafter, the number of the elevator to be determined by the determination unit 112 will be referred to as "C". For example, when C=1, the determination unit 112 makes a determination for the first car, and when C=2, the determination unit 112 makes a determination for the second car. First, the determination unit 112 sets C=1 (S4), and determines whether or not it is predicted that there is a possibility that interference will occur when the C-th car is assigned to the information processing device 2A.

The determination unit 112 refers to the hall destination floor DB 131 and identifies an existing call that has already been registered in the C-car. Determination unit 112 determines the departure floor and destination floor included in the specified existing call and allocation request data newly acquired from reception unit 111, that is, the departure floor and destination floor included in the new destination floor call from information processing device 2A. , and the determination is made by comparing with . Note that if there are a plurality of existing calls to which the C-car is assigned, the determination unit 112 makes determinations for all of these existing calls.

Specifically, the determination unit 112 determines whether (A) car C is the departure floor of the information processing device 2A and whether there is a plan to get off another information processing device 2B when the information processing device 2A gets on. Determine (S5). Since the specific example of (A) has already been explained, the explanation is omitted. In the case of YES in S5, the determination unit 112 determines that interference may occur between the information processing device 2A and the information processing device 2B if the C car is assigned to the information processing device 2A. output to

In the case of NO in S5, the determination unit 112 next determines whether (B) car C is scheduled to board another information processing device 2B when the information processing device 2A gets off at the destination floor of the information processing device 2A; is determined (S6). Since the specific example of (B) has already been explained, the explanation will be omitted. In the case of YES in S6, the determination unit 112 determines that interference may occur between the information processing devices 2A and 2B if the C-type machine is assigned to the information processing device 2A. output to

In the case of NO in S<b>6 , the determination unit 112 determines that interference will not occur even if the C-th car is assigned to the information processing device 2</b>A, and outputs the determination result to the identification unit 113 .

The identification unit 113 identifies the candidate car based on the determination result of the determination unit 112 . If no interference occurs even if the C car is assigned to the information processing device 2A (NO in both S5 and S6), the specifying unit 113 adds the C car to the candidate cars (S7). On the other hand, if interference may occur when assigning car C to the information processing device 2A (YES in S5 or S6), the identifying unit 113 excludes car C from the candidate cars.

If the determination unit 112 has not completed determination regarding interference for all elevators 5 (NO in S8), 1 is added to C (S9). After that, the processes of S5 to S8 are repeated until YES in S8.

When the determination unit 112 completes the interference determination for all elevators 5 (YES in S8), the identification unit 113 outputs information indicating the elevators added to the candidate elevators so far to the elevator allocation unit 114.

When the information indicating the candidate car is obtained from the identification unit 113, the car allocation unit 114 determines the car to be allocated (S10: car allocation step). decide. As a method for determining the number of elevators to be assigned, a method conventionally used for allocating elevator numbers may be used. When the target of use is the user, all elevators of the elevator 5 are candidate elevators. Further, when the target of use is the information processing device 2A, among the elevator cars of the elevator 5, a car that does not cause interference with the information processing device 2B in which the existing call has been registered becomes a candidate car.

Subsequently, when the assigned elevator car is determined, the elevator assigning unit 114 causes the hall destination floor DB 131 and the elevator DB 132 to store each piece of information based on the received destination floor call and the determined assigned elevator in association with each other. In addition, the elevator car assignment unit 114 transmits information indicating the assigned elevator car to the recipient of the assignment request data, that is, to the user who sent the destination floor call (S11). This completes the registration of the destination floor call.
