TECHNICAL FIELD The present invention relates to an elevator management device that manages an elevator having a destination floor registration function, a control method for an elevator management device, an elevator management system, and a self-propelled device.

In some recent elevators, a destination floor registration function has been introduced. An elevator having a destination floor registration function allows users to register destination floors in advance, and assigns the optimum number (optimal number) to each user based on the registered destination floors. This effectively shortens the time the user waits for the arrival of the elevator and the time it takes for the user to reach the destination floor.

In recent years, the use of elevators by self-propelled devices such as robots is increasing. The elevator apparatus of Patent Document 1 detects the number of passengers already in the car, which is the number of passengers in the car. The number of people waiting to board is detected, which is the number of passengers waiting. Then, the elevator apparatus of Patent Document 1 controls the self-propelled apparatus to get off at the floor before reaching the destination floor when the total number of people of the number of existing passengers and the number of people waiting to board is equal to or more than the threshold number of people. .

The elevator control system of Patent Document 2 determines the number of passengers who are not suitable to ride with the self-propelled device based on the boarding state in the car, and the number of passengers who are difficult to ride with the self-propelled device exceeds a predetermined number. If it exceeds, it is determined that the self-propelled device is prohibited from riding in the car.

[Embodiment 1]
An embodiment of the present invention will be described in detail below.

(Overview of Elevator Management System 100)
FIG. 1 is a diagram showing an example of the configuration of an elevator management system 100 according to Embodiment 1 of the present invention. The elevator management system 100 is a system that manages an elevator 4 provided in a building having multiple floors. The elevator management system 100 is a system capable of notifying the user (person) of the elevator 4 having a destination floor registration function and the self-propelled device 6 such as a robot of the optimum number. Hereinafter, the user and the self-propelled device 6 may be collectively referred to as the target of use. Note that the number of users may be one, or may be multiple. The number of self-propelled devices 6 may be one, or plural. A case where there is only one user will be described below.

Here, the "destination floor registration function" is a function for allocating the optimum car according to the destination floor to be used and guiding the optimum car as the car to be boarded by the use target. By adopting the destination floor registration function, it is possible to effectively shorten the time the user 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 "optimum number" is the elevator number of the elevator 4 assigned to each allocation request operation by the elevator management device 1 of the elevator management system 100 having a destination floor registration function in response to the allocation request operation of the utilization target. . The "elevator number to be assigned to the allocation request operation" is intended to be the elevator number of the elevator 4 determined by the elevator management device 1 as the optimum number to be used by the utilization target who performed the allocation request operation. A case where the elevator 4 has a plurality of elevators will be described below as an example, but the present invention is not limited to an elevator having a plurality of elevators. FIG. 1 illustrates an elevator 4 having multiple cars. In the following, a case where the elevators 4a to 4c are No. 1 to No. 3 respectively will be described as an example.

The "allocation request operation" is an operation for registering allocation request data including destination floors in advance in the elevator management device. The "allocation request operation" is also called "destination floor call registration operation". If the target of use is a user, the allocation request operation may be, for example, an operation in which the user inputs a desired destination floor or the like to the destination floor call registration device 2 installed on the departure floor. . The destination floor call registration device 2 may transmit to the elevator management device 1 information including information indicating the input destination floor and information on the floor where the destination floor call registration device 2 is installed. The user may directly transmit the allocation request data to the elevator management device 1 using a mobile terminal such as a smart phone without going through the destination floor call registration device 2 . When the object to be used is the self-propelled device 6, the assignment request operation is, for example, the self-propelled device 6 directly transmitting the assignment request data to the elevator management device 1 to request the assignment.

The self-propelled device 6 in the elevator management system 100 may be an automatic transport device, a self-propelled cleaning device, other multifunctional robots, etc., which are pre-installed in the building. Alternatively, the self-propelled device 6 may be a dedicated device deployed in the building in accordance with the introduction of the elevator management system 100 . In addition to the self-propelled function, the self-propelled device 6 may have a function of notifying the user of a message (for example, an audio output function, a screen display function, etc.).

(Technical Concept of Elevator Management System 100)
First, the technical concept of the elevator management system 100 will be described with reference to FIGS. 12 and 13. FIG. 12 and 13 are plan views showing the interior of the elevator 4a of the elevator management system 100. FIG. The self-propelled device 6 autonomously transmits allocation request data to the elevator management device 1 and registers destination floors and the like in the elevator management device 1 . Also, the self-propelled device 6 gets on the optimum number determined by the elevator management device 1 and gets off at the registered destination floor.

A capacity is set for the elevator 4 . "Capacity" can be the maximum number of people that can be accommodated in the car of the elevator 4, or the maximum weight that can be accommodated. Elevator 4 cannot take users and self-propelled devices 6 that exceed capacity. Here, it is assumed that the optimum elevator is elevator 4a, which is elevator No. 1, and the capacity of elevator No. 1 is eight.

In FIG. 12, one self-propelled device 6 and four users are on the elevator 4a. Here, it is assumed that the size of the self-propelled device 6 is for one user and the weight is for four users. In such a case, the elevator 4a has already reached its capacity. Therefore, when the self-propelled device 6 or the user is assigned to this elevator 4a, the elevator 4a will pass the departure floor because the capacity will be exceeded if these users get on the elevator 4a. Therefore, the self-propelled device 6 or the user cannot get on the elevator 4a.

In FIG. 13, one self-propelled device 6 and three users are on the elevator 4a. When the self-propelled device 6 occupies a space for five people in plan view, the elevator 4a has already reached its capacity. When the self-propelled device 6 or the user is assigned to the elevator 4a, even if the self-propelled device 6 or the user tries to get on from his or her departure floor, there is no space in the elevator 4a for boarding. Therefore, the self-propelled device 6 and the user cannot get on the elevator 4a.

The reason why the elevator 4a cannot be boarded as described above is that the number of the self-propelled devices 6 is used in determining whether or not to allow allocation. This is because it is assumed that fixed values are used. Therefore, as described above, if the self-propelled device 6 is heavier than the weight of one user, or if the self-propelled device 6 is larger than the horizontal dimension of one user, substantially The capacity is reached and neither the self-propelled device 6 nor the user can board the assigned elevator.

An elevator management device 1 of the present disclosure manages operation of an elevator 4 provided in a building having multiple floors. In addition, the elevator management device 1 determines whether or not to assign the self-propelled device 6 to the car of the elevator 4 . The elevator management device 1 calculates the conversion value, that is, the number of people to be converted N, the number of users already assigned to the elevator from the departure floor to the destination floor of the self-propelled device 6, that is, the number of users npsg, and the elevator It may be determined whether or not to assign based on the conversion number N of other self-propelled devices 6 that have already been assigned.

The converted number of people N is a value obtained by converting at least one of the weight and horizontal dimension of the self-propelled device 6 into the number of users. Specifically, the converted number of people N is a weight conversion value Nw obtained by converting the weight of the self-propelled device 6 into the number of users, and a dimension obtained by converting the horizontal dimension of the self-propelled device 6 into the number of users. Either conversion value Na may be used. The converted number of people N is used as the number of users npsg of the self-propelled device 6 . In the present embodiment, the larger one of the weight conversion value Nw and the dimension conversion value Na is specified as the conversion number N. However, a value specified based on the weight conversion value Nw and the dimension conversion value Na (eg, the average value of the weight conversion value Nw and the dimension conversion value Na) may be specified as the conversion number N.

By using the conversion number N, the elevator management device 1 can determine whether or not to assign based on values equivalent to the actual weight and/or horizontal dimension of the self-propelled device 6 . Therefore, it is possible to reduce the possibility that the self-propelled device 6 or the user cannot get on the assigned elevator.

The destination floor call registration device 2 is provided at the elevator platform on each floor of the building. The destination floor call registration device 2 receives an allocation request operation by the user and transmits the input allocation request data such as the destination floor to the elevator management device 1 . Identification information (ID) assigned to each destination floor call registration device 2 is used in communication between the elevator management device 1 and the destination floor call registration device 2 . For example, the ID of the destination floor call registration device 2 placed on the first floor may be "DESTREG-001", and the ID of the destination floor call registration device 2 placed on the second floor may be "DESTREG-002". The elevator management device 1 transmits the information of the optimum elevator assigned according to each allocation request operation to the destination floor call registration device 2, and the user confirms the optimum elevator on the display screen of the destination floor call registration device 2 or the like. When a user directly transmits allocation request data from a mobile terminal to the elevator management device 1 without going through the destination floor call registration device 2, an ID is assigned to each user, and the corresponding ID is used for communication between the mobile terminal and the elevator. ID is used. A case where a user performs an allocation request operation via the destination floor call registration device 2 will be described below.

The self-propelled device 6 transmits allocation request data to the elevator management device 1 as described later. The elevator management device 1 transmits to the self-propelled device 6 information on the optimum elevator car allocated according to the allocation request data.

The elevator control device 3 controls operation of the elevator 4 . The elevator control device 3 is provided corresponding to each car of the elevator 4 . For example, the elevator controller 3a controls the operation of the elevator 4a, and the elevator controller 3b controls the operation of the elevator 4b. In addition, in the elevator management system 100, the number of elevator control devices 3 and elevators 4 is plural.

The self-propelled device management device 5 controls the movement, operation, etc. of the self-propelled device 6 deployed in the building. When a plurality of self-propelled devices 6 are deployed in a building, in communication between the self-propelled device management device 5 and the self-propelled devices 6, identification information given to each self-propelled device 6 ( ID) is used. The self-propelled device management device 5 is configured to appropriately receive from the self-propelled device 6 information indicating the current position of the self-propelled device 6 and work status information including information on the work currently being performed. may As a result, the self-propelled device management device 5 can monitor and control the position and work status of each self-propelled device 6 . The self-propelled device management device 5 may, for example, determine the departure floor and destination floor of the self-propelled device 6 and transmit information on the departure floor and destination floor to the self-propelled device 6 . The self-propelled device management device 5 may transmit work status information and the like to the elevator management device 1 .

(Configuration of elevator management device 1)
A configuration of the elevator management device 1 will be described with reference to FIG. FIG. 2 is a diagram showing an example of the configuration of the elevator management device 1. As shown in FIG.

The elevator management device 1 is a computer communicably connected to the destination floor call registration device 2, the elevator control device 3, and the like.

The control unit 11 is a CPU (Central Processing Unit), and the control unit 11 controls to execute processing of each function provided in the elevator management device 1 . The control unit 11 receives the allocation request data from the utilization target, and determines whether or not to allocate the utilization target elevator to the elevator car based on the received allocation request data and the already allocated elevator car information. The control unit 11 determines the optimum car from among allocatable car candidates, and allocates the use target to the optimum car. In addition, the control unit 11 comprehensively manages the operation of each car.

The control unit 11 includes a management unit 111, a determination unit 112, an allocation unit 113, and a communication control unit 114, for example.

The management unit 111 manages operation of the elevator 4 . For example, the management unit 111 generates, for the number of elevators 4 determined by the allocation unit 113, a stop floor setting instruction that sets a stop floor for stopping at the departure floor and destination floor of the elevator to be boarded. . The management unit 111 transmits a stop floor setting instruction to the elevator control device 3 corresponding to the elevator car of the elevator 4 via the communication control unit 114 . Also, for example, the management unit 111 determines whether or not allocation request data has been received from the use target via the communication control unit 114 . When the management unit 111 receives the allocation request data, it specifies the date and time of reception, the registration source ID, the attributes to be used, the departure floor, the destination floor, and the converted number of people N included in the allocation request data, and stores them in the registration information table 121. do.

In this embodiment, the management unit 111 comprehensively manages the operation of each elevator 4 . Note that the management unit 111 may have the functions of the elevator control device 3 . In this case, the elevator management system 100 does not have to include the elevator control device 3 .

When the allocation request data is received from the utilization target, if the utilization target attribute is the self-propelled device 6, the determination unit 112 converts the weight and/or the horizontal dimension of the self-propelled device 6 into the number of users. The number of users npsg is specified based on the converted value (converted number of people N). If the attribute to be used is user, the number of users npsg is set to 1. Then, the number of users npsg already assigned to the elevator number from the departure floor to the destination floor of the self-propelled device 6 and the conversion number N of other self-propelled devices 6 already assigned to the elevator number Based on the above, decide whether or not to assign. The determining unit 112 determines whether or not the usage target can be assigned for all the elevator cars. The determination unit 112 stores the allocatable car number in the allocation candidate list 122 .

The allocating unit 113 determines the optimum car from among the cars stored in the allocation candidate list 122 . The allocating unit 113 calculates, for example, the waiting time of the passenger waiting at the departure floor from among the cars stored in the allocation candidate list 122, and selects the car with the shortest time as the optimum car.

The communication control unit 114 controls the communication unit 13 to communicate with the destination floor call registration device 2 , the elevator control device 3 , the self-propelled device management device 5 and the self-propelled device 6 . Specifically, the communication control unit 114 receives allocation request data from the destination floor call registration device 2 or the self-propelled device 6, and transmits the information of the optimum number to the destination floor call registration device 2 or the self-propelled device 6. to control.

The storage unit 12 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. A registration information table 121 is stored in the storage unit 12 . An allocation candidate list 122 is also stored in the storage unit 12 . In the allocation candidate list 122, the numbers of allocable machines are displayed. is stored.

Table 1 shows an example of the registration information table 121 .

The registration information table 121 has items of, for example, reception date and time, registration source ID, use object attribute, departure floor, destination floor, number of converted persons N, number of users npsg, and optimum number. Information included in the allocation request data may be registered in the registration information table 121 in the order in which the elevator management apparatus 1 receives the allocation request data, for example.

When the allocation request data is received, the management unit 111 specifies the date and time of reception, the registration source ID, the attributes to be used, the departure floor, the destination floor, and the number of people to be converted N included in the allocation request data. , “registration source ID”, “use target attribute”, “departure floor”, “destination floor”, and “converted number of people N”. The date and time when the elevator management device 1 receives the allocation request data from the self-propelled device 6 or the user is stored in the column of "receipt date and time". For example, year, month, day, hour, minute and second are stored in the "receiving date and time column". The column of "registration source ID" stores information for identifying the target of use. In the "registration source ID" column, the ID of the destination floor call registration device 2 is stored when the usage target attribute of the usage target is the user, and when the usage target attribute of the usage target is the self-propelled device 6 , the ID of the self-propelled device 6 is stored. In the column of "use object attribute", information indicating "user" or "self-propelled device" is stored according to the use object. In the column of "departure floor", the floor where the user gets on the elevator 4 is stored. The column of “destination floor” stores the floor where the user gets off the elevator 4 . In the "converted number of people N" column, no information is stored when the object of use is the user, and when the object of use is the self-propelled device 6, the number of the self-propelled device 6 is converted into the number of users. The converted number of people N is stored.

The determination unit 112 refers to the converted number of people N stored in the registration information table 121 to specify the number of users npsg, and stores it in the column of "number of users npsg". The determining unit 112 stores "1" when the target of use is the user. When the object of use is the self-propelled device 6, the determination unit 112 stores the value of the "converted number of people N" specified as the number of users npsg. The allocating unit 113 determines the optimal car number from among the determined allocable car numbers and stores it in the "optimal car number" column.

For example, in the "No. 1" row of Table 1, at 10:50:20 on December 8, 2021, an allocation request from the destination floor call registration device 2 whose registration source ID is "DESTREG-001" Registration information when data is received is shown. The registration source ID "DESTREG-001" is the destination floor call registration device 2 installed on the first floor. This destination floor call registration device 2 is a device that receives an allocation request operation by a user who wishes to move from the "1" floor to the "10" floor. Since it is registration information from the user, it is not stored in the column of "converted number of people N", but is stored as "1" in the column of "number of users npsg". This user is assigned the number "1" by the assigning unit 113, and "1" is stored in the "optimal number" column.

The row of “No. The registration information is transmitted from the self-propelled device 6, and the registration source ID is "ROBOT-002". For example, the self-propelled device 6 moves from the "3" floor with the baggage loaded, and performs the work of handing over the baggage on the "8" floor. Therefore, during the movement from the "3" floor to the "8" floor, the load is heavy and the "converted number of people N" and the "number of users npsg" are "5.5". That is, while the "converted number of people N" is "2.4" when the self-propelled device 6 does not carry any luggage, the "converted number of people N" increases to "5.5" because it carries luggage. ing. "1" is assigned to this self-propelled device.

The "No. 3" row in Table 1 shows the registration information when the allocation request data is received from the registration source ID "ROBOT-001" at 10:51:25 on December 8, 2021. It is For example, the self-propelled device 6 moves from the "2nd" floor with the baggage loaded, and performs the work of handing over the baggage on the "9th" floor. Therefore, while moving from the "3rd" floor to the "9" floor, it is heavy because the luggage is loaded, and the "converted number of people N" and the "number of users npsg" are "3.5". That is, while the "converted number of people N" is "1.5" when the self-propelled device 6 does not carry any luggage, the "converted number of people N" increases to "3.5" because it carries luggage. ing. Here, the management unit 111 sets the date and time of reception, the ID of the registration source, the attribute of use object, the departure floor, the destination floor, and the number of people to be converted N as “date and time of reception”, “ID of the registration source”, “attribute of use object”, “departure floor , 'destination floor', and 'converted number of people N', and the determining unit 112 identifies the number of users npsg and stores it in the column of 'number of users npsg'. From this, the deciding unit 112 decides whether or not to assign the self-propelled device 6 to the first car, and after the assigning unit 113 decides the optimum car number, the optimum car number is stored in the "optimal car number" column.

The registration information table 121 stores the registration information of all usage targets. The registration information is updated each time allocation request data is received from a user, each time the number of users npsg is specified, and each time an optimum machine number is determined. As described above, in Table 1, the user whose destination floor call registration device 2 ID is "DESTREG-001" and the self-propelled device 6 whose ID is "ROBOT-002" have already been assigned No. 1. ing. Then, the allocation request data is received from the self-propelled device 6 whose ID is "ROBOT-001", and the state in which the registration source ID, user attribute, departure floor, destination floor, and number of people converted (N) are stored. showing.

The communication unit 13 is an interface for performing communication via a communication network such as a wireless LAN (Local Area Network). The communication unit 13 receives allocation request data from the destination floor call registration device 2 or the self-propelled device 6 and transmits information on the optimum car to the destination floor call registration device 2 or the self-propelled device 6 .

Information indicating the self-propelled device is registered in the column of "use target attribute" as the use target attribute. An ID unique to the self-propelled device 6 is stored in the "registration source ID" column. In the columns of "departure floor" and "destination floor", the departure floor and destination floor received together with the transport instruction when the management unit 61 receives the transport instruction from the self-propelled device management device 5, for example, are stored. ing.

The weight conversion value Nw may be a conversion value calculated based on the weight of the self-propelled device 6, as described above. The column of "converted weight value Nw" stores a value obtained by converting the weight of the self-propelled device 6 by the average weight of users CWeight to convert the weight into the number of users. The average weight CWeight may be the weight commonly used in the elevator industry. An example of the average body weight CWeight is 65 kg. The dimension conversion value Na is a conversion value calculated based on the horizontal dimension of the self-propelled device 6 . The column of "size conversion value Na" stores a value converted into the number of users by dividing the horizontal size of the self-propelled device 6 by the average horizontal size of the users. The horizontal dimension may be, for example, the area when the self-propelled device 6 and the user are viewed from above. This area is the occupied area Area that occupies the elevator 4 when the self-propelled device 6 and the user get on the elevator 4 . Also, the average dimension may be, for example, the average value CArea of the areas of a plurality of users having an average weight when viewed from above. An example of this average value CArea is 0.8 m ² .

In the column of “number of people to be converted N”, the number of people to be converted N specified by the calculation unit 62 based on the weight conversion value Nw and the dimension conversion value Na, specifically, the larger one of the weight conversion value Nw and the dimension conversion value Na is stored.

The management unit 61 updates the departure floor and destination floor in the columns of "departure floor" and "destination floor" every time it receives the information of the departure floor and destination floor. As will be described later, the calculation unit 62 calculates the weight conversion value Nw and the dimension conversion value Na in the columns of "weight conversion value Nw" and "dimensional conversion value Na" each time the weight conversion value Nw and the dimension conversion value Na are calculated. Update. Further, the calculation unit 62 refers to the weight conversion value Nw and the dimension conversion value Na stored in the registration information table 661 and updates the conversion number N in the “conversion number N” column each time the conversion number N is specified. The communication control unit 63 transmits to the elevator management apparatus 1 allocation request data including the usage target attribute, the registration source ID, the departure floor, the destination floor, and the conversion number N stored in the registration information table 661 . When receiving information on the optimum elevator car from the elevator management device 1 , the management unit 61 stores the optimum elevator car in the registration information table 661 .

For example, Table 2 shows the case where the self-propelled device 6 whose registration source ID is "ROBOT-001" moves from the "2nd" floor with a load and delivers the load on the "9th" floor. indicates During the movement from the "2" floor to the "9" floor, it is heavy because it is loaded with luggage, and the "weight conversion value Nw" is "3.5". That is, while the "weight conversion value Nw" is "1.5" when the self-propelled device 6 does not have any baggage, the "weight conversion value Nw" is up to "3.5" because it has baggage. It has increased. The "dimensional conversion value Na" is "0.09", which is smaller than the "weight conversion value Nw" of "3.5". "3.5" of the "converted weight value Nw" is selected and specified as the "converted number of people N". The first machine is stored as the "optimum machine".

The moving mechanism 64 is a driving mechanism for moving the self-propelled device 6 . Movement mechanism 64 may be any drive mechanism such as wheels, caterpillars, and walking legs.

The communication unit 65 is an interface for performing communication via a communication network such as a wireless LAN. The communication unit 65 performs communications such as receiving instructions for transporting luggage from the self-propelled device management device 5, transmitting allocation request data to the elevator management device 1, and receiving information on the optimum elevator car from the elevator management device 1. I do.

(Configuration of Elevator Control Device 3 and Elevator 4)
Next, configurations of the elevator control device 3 and the elevator 4 will be described with reference to FIG. FIG. 4 is a diagram showing an example of the configuration of the elevator control device 3 and the elevator 4. As shown in FIG.

The elevator 4 includes a car 41 for boarding users, etc., an operation control panel 40 for controlling the elevation of the car 41, and a door 42 provided at the landing of each floor for each car.

The elevator control device 3 is, for example, a computer provided for each car of the elevator 4 and connected to the elevator 4 so as to be communicable. For example, the elevator controller 3 controls operation of the elevator 4 .

The elevator control device 3 has a control section 30 . The control unit 30 is a CPU, and the control unit 30 controls to execute processing of each function provided in the elevator control device 3 .

The control unit 30 includes, for example, an instruction acquisition unit 31, a driving situation management unit 32, and a door opening/closing control unit 33.

The instruction acquisition unit 31 acquires from the elevator management device 1 various instructions associated with the results of allocation of the optimum elevator car and various instructions associated with allocation changes. Instructions acquired by the instruction acquisition unit 31 include a stop floor setting instruction, a destination floor setting instruction, and the like.

The operating status management unit 32 acquires from the operation control panel 40 each information indicating the position of the car 41 of the elevator 4, the operating status, the opening/closing status of the door 42 of each floor, and the like.

The door opening/closing control unit 33 controls the opening/closing of the door 42 of the landing of the designated floor according to the instruction from the elevator management device 1 . For example, the door opening/closing control unit 33 can cause the elevator 4 to hold the door 42 of the elevator 4 at the landing of the designated floor in an open state, or cancel the holding of the open state. .

(Processing performed by elevator management device 1)
Next, an example of processing performed by the elevator management device 1 will be described with reference to FIG. FIG. 5 is a flowchart showing an example of processing by the control unit 11 of the elevator management device 1. As shown in FIG.

The management unit 111 determines whether the allocation request data transmitted by the destination floor call registration device 2 or the self-propelled device 6 has been received via the communication control unit 114 (step S1). When determining that allocation request data has not been received (step S1: NO), the management unit 111 repeats step S1.

If the determination unit 112 determines that the allocation request data has been received by the management unit 111 (step S1: YES), the determination unit 112 determines the registration source ID, usage target attribute, departure floor, destination floor, and conversion data included in the allocation request data. The number N is specified and stored in the registration information table 121 (step S2). The determination unit 112 determines whether or not the utilization target attribute included in the allocation request data indicates the self-propelled device 6 (step S3). When the determination unit 112 receives the allocation request data from the self-propelled device 6 , the allocation request data includes a utilization target attribute indicating the self-propelled device 6 . Therefore, the determination unit 112 determines that the transmission source of the allocation request data is the self-propelled device 6 . When the determination unit 112 receives the allocation request data from the destination floor call registration device 2, the allocation request data includes a usage target attribute indicating the user. Therefore, the determination unit 112 determines that the source of the allocation request data is the user.

When determining that the transmission source of the allocation request data is the self-propelled device 6 (step S3: YES), the determining unit 112 specifies the converted number of people N included in the allocation request data as the number of users npsg. (Step S4). If the determination unit 112 determines that the source of the allocation request data is not the self-propelled device 6, that is, the user (step S3: NO), it sets the number of users npsg to 1 (step S5).

The determination unit 112 first determines the number of the machine. is set to 1 (step S6). That is, the determination unit 112 first determines whether or not the self-propelled device 6 or the user can be assigned to the first elevator 4a. The determination unit 112 determines whether or not the number of passengers indicated by the number of passengers npsg is equal to or less than the capacity n ( step S7). The determination unit 112, for example, refers to the registration information table 121, and on each floor from the departure floor to the destination floor of the use target, the npsg of the user or the self-propelled device 6 already assigned to the c Add the npsg of the usage target to the total value of Then, the determination unit 112 determines whether or not the number of occupants on each floor is equal to or less than the capacity n (e.g., 8 persons). In addition, in step S7 immediately after step S6, the determination part 112 determines about the elevator 4a.

As an example, as shown in Table 1, the elevator 4a has already been assigned to the user whose registration source ID is "DESTREG-001" and the self-propelled device 6 whose registration source ID is "ROBOT-002". Suppose there is In addition, it is assumed that the determination unit 112 determines whether or not the allocation to the elevator 4a is possible, and the capacity n=8.

A case where the control unit 11 receives allocation request data from the self-propelled device 6 whose registration source ID is "ROBOT-001" will be taken as an example. At the departure floor of the self-propelled device 6, one user whose number of users npsg is 1 has already boarded the elevator 4a. Here, the self-propelled device 6 with the number of users npsg of 3.5 boarded on the second floor, and another self-propelled device 6 with the number of users npsg of 5.5 already assigned Suppose you board the train later on the 3rd floor. At this time, the total number of users npsg on the third floor is 10 (persons) (=1+3.5+5.5). The determination unit 112 calculates as described above and determines that the capacity (n=8) is exceeded when the self-propelled device 6 is boarded on the elevator 4a. Since the capacity is exceeded, the determination unit 112 does not assign the elevator 4a to the self-propelled device 6 that has not yet been assigned.

If the total value of the number of users npsg on the third floor is 8 or less, the determining unit 112 makes the above determination on higher floors. As described above, the determination unit 112 determines whether or not the number of users npsg is equal to or less than the capacity n on each floor between the departure floor and the destination floor for which allocation is requested. When the total value of the number of users npsg is equal to or less than the capacity n on all floors from the departure floor to the destination floor to be used, the determination unit 112 causes the self-propelled device 6 to get on the elevator 4a. It is determined that the number of participants is below the capacity.

When determining that the total number of users npsg exceeds the capacity n (step S7: NO), the determination unit 112 advances the process to step S9. If the determining unit 112 determines that the total value of the number of users npsg is equal to or less than the capacity n (step S7: YES), the determining unit 112 determines that the No. is added to the allocation candidate list 122 (step S8). Then, the determining unit 112 adds 1 to the value of c (step S9).

For example, the determination unit 112 adds a value of “1” indicating the elevator 4a to the allocation candidate list 122 when performing the process of step S8 via step S7 immediately after step S6. Then, the determination unit 112 sets c=2 in step S9, and the determination unit 112 determines the elevator 4b included in the second car.

The determining unit 112 determines whether or not c is greater than the total number of cars m (step S10). When determining that c is equal to or less than the total number of cars m (step S10: NO), the determination unit 112 returns the process to step S7. As a result, the determination unit 112 executes processing for all cars.

If the determination unit 112 determines that c is greater than the total number of elevators m (step S10: YES), the determination unit 112 has performed determination processing for all elevators included in the elevator management system 100 . Therefore, in this case, the allocation unit 113 selects the optimum car from the allocation candidate list 122 and determines the selected car as the optimum car (step S11). As described above, the allocating unit 113 determines, for example, the car with the shortest waiting time at the departure floor as the optimum car.

The communication control unit 114 transmits the information of the optimum number machine to the utilization target that has transmitted the allocation request data (step S12), and ends the process. When the target of use is the self-propelled device 6 , the communication control unit 114 transmits the information of the optimum number to the self-propelled device 6 . When the target of use is a user, the communication control unit 114 transmits the information of the optimum car to the destination floor call registration device 2 for which the user has performed the allocation request operation.

(Control Method of Elevator Management Device 1)
The control method of the elevator management device 1 includes a management step of managing the operation of an elevator 4 provided in a building having multiple floors, and a decision step of deciding whether or not to assign the self-propelled device 6 to the elevator 4. include. In the management step, the operation of the elevator 4 is managed by the management section 111 of the elevator management device 1 . The above step S1 corresponds to the management step.

In the determination step, the converted number of people N based on the weight conversion value Nw and the dimension conversion value Na of the self-propelled device 6, and the number of elevators 4 already assigned between the departure floor and the destination floor of the self-propelled device 6 Based on the user number npsg of the user and the user number npsg of the other self-propelled device 6, whether or not to assign is determined. The above step S6 corresponds to the determination step.

(Processing performed by self-propelled device 6)
FIG. 6 is a flow chart showing an example of the above processing by the control unit 60 of the self-propelled device 6. As shown in FIG.

The management unit 61 determines whether or not to use the elevator 4 (step S21). The management unit 61 determines that the elevator 4 is to be used, for example, when a transportation instruction indicating transportation of luggage to a predetermined floor is received from the self-propelled device management device 5 .

When the management unit 61 determines to use the elevator 4 (step S21: YES), the calculation unit calculates the weight conversion value Nw (step S22). As an example, the calculation unit 62 calculates the weight conversion value Nw from the following formula (1), and stores it in the registration information table 661;
Nw=Weight/CWeight (1)
However, Weight: Current weight of the self-propelled device 6 CWeight: Average weight of a person (65 kg as an example)
For example, when the weight of the self-propelled device 6 is 230 kg, it is calculated as 230/65≈3.5 (persons), and the weight conversion value Nw is 3.5.

The calculator 62 calculates the dimension conversion value Na (step S23). As an example, the calculation unit 62 calculates the dimension conversion value Na using the following formula (2). Here, as the dimension conversion value Na, the maximum value of the dimension in one direction of the self-propelled device 6 in plan view (hereinafter referred to as the horizontal dimension) is added to the dimension in the direction substantially perpendicular to the one direction (hereinafter referred to as the vertical dimension). The occupied area Area, which is the area obtained by multiplying the maximum value of ), is used. The calculator 62 stores the dimension conversion value Na in the registration information table 661;
Na=Area/CArea (2)
However, Area: occupied area calculated from the horizontal and vertical dimensions of the current self-propelled device 6 CArea: occupied area calculated from the horizontal and vertical dimensions of a person having an average physique (for example, 0. ^8m2 )

The calculator 62 determines whether weight conversion value Nw>dimension conversion value Na (step S24). When it is determined that the weight conversion value Nw>the dimension conversion value Na (step S24: YES), the calculation unit 62 sets the weight conversion value Nw to the conversion number N and stores it in the registration information table 661 (step S25).

If the calculation unit 62 determines that the weight conversion value Nw is not greater than the size conversion value Na, that is, if the weight conversion value Nw≦the size conversion value Na (step S24: NO), the size conversion value Na is set as the number of people to be converted N, and the registration information It is stored in the table 661 (step S26).

That is, the calculation unit 62 specifies the larger one of the weight conversion value Nw and the dimension conversion value Na as the conversion number N. Therefore, when the elevator management device 1 specifies the converted number of people N as the number of users npsg, the larger one of the weight conversion value Nw and the dimension conversion value Na can be used. Therefore, the possibility that the elevator management apparatus 1 determines whether or not to permit the allocation of a passenger can more reliably reduce the possibility of a state in which boarding is not possible. The processes of steps S25 and S26 may be performed in reverse order, or may be performed in parallel.

For example, when a transport instruction is received from the self-propelled device management device 5, the management unit 61 also receives information indicating the departure floor (the floor where the self-propelled device 6 is located) and the destination floor, and stores the information in the registration information table. 661 is stored. Therefore, the management unit 61 identifies the departure floor and the destination floor of the self-propelled device 6 by referring to the registration information table 661 (step S27).

After that, the communication control unit 63 transmits allocation request data to the elevator management device 1 (step S28). The communication control unit 63 refers to the registration information table 661 as the allocation request data, and obtains, for example, information including the departure floor, the destination floor, and the number of people to be converted N, which are specified as described above, together with the usage target attribute and the registration source ID. Send.

After that, the management unit 61 determines whether or not information on the optimum elevator car has been received from the elevator management device 1 via the communication control unit 63 (step S29). When the management unit 61 determines that the information on the optimum machine number has not been received (step S29: NO), the step S29 is repeated.

If the management unit 61 determines that the information on the optimum machine number has been received (step S29: YES), the management unit 61 stores the optimum machine number in the registration information table 661 (step S30), and terminates the process.

(Updating process of weight conversion value Nw and dimension conversion value Na performed by self-propelled device 6)
In the processing shown in FIG. 6, the case where the management unit 61 calculates the weight conversion value Nw and the dimension conversion value Na each time it determines that the self-propelled device 6 uses the elevator 4 has been described, but the present invention is not limited to this. . The calculator 62 may calculate the weight conversion value Nw each time the weight of the self-propelled device 6 changes and store it in the registration information table 661 . Further, the calculation unit 62 may calculate the dimension conversion value Na each time the horizontal dimension of the self-propelled device 6 changes and store it in the registration information table 661 . In this case, when the control unit 60 determines that the elevator 4 is to be used, the weight conversion value Nw and the dimension conversion value Na may be read out from the registration information table 661, and steps S24 to S30 may be performed.

FIG. 7 is a flow chart showing an example of the above processing by the control unit 60 of the self-propelled device 6. As shown in FIG.

The calculator 62 determines whether or not the weight of the self-propelled device 6 has changed (step S31). For example, the weight is calculated when the self-propelled device 6 is loaded with a load and when the self-propelled device 6 is carrying the load, and when the self-propelled device 6 goes to receive the load, that is, when the self-propelled device 6 is loaded with the load. It's different if you don't. Also, the weight Weight changes each time, for example, when the self-propelled device 6 is loaded with or unloaded with baggage. For example, when the self-propelled device management device 5 issues a transport instruction to transport a load of B kg, the calculator 62 determines that the weight of the self-propelled device 6 has changed. In this case, the self-propelled device 6 will hold a load of B kg, and for example, its own weight of A kg will be increased by +B kg. For example, when the transportation instruction is not received, the calculation unit 62 determines that the weight has not changed. In this case (step S31: NO), the calculator 62 advances the process to step S33.

When determining that the weight Weight has changed (step S31: YES), the calculation unit 62 substitutes ((A+B) kg) for the weight Weight in the above equation (1) to calculate the weight conversion value Nw, and calculates the weight conversion value Nw. The values in the table 661 are updated (step S32).

Further, the calculation unit 62 determines whether or not the occupied area Area has changed (step S33). The occupied area Area becomes larger, for example, when a load having a large horizontal dimension is loaded. For example, the calculation unit 62 transports a package in which the self-propelled device 6 itself has an occupied area Area of Cm ² and the self-propelled device management device 5 has an occupied area Area of Dm ² in plan view in a horizontal position. If the transportation instruction to that effect has been received, it is determined that the occupied area Area has changed to ^Dm2 (step S33: YES). The calculation unit 62 substitutes ^Dm2 for the occupied area Area in the above equation (2) to calculate the dimension conversion value Na, updates the value of the registration information table 661 (step S34), and ends the process.

Note that steps S31 and S32 and steps S33 and S34 may be performed in reverse order, or may be performed in parallel. Alternatively, the control unit 60 may update the weight Weight without updating the weight conversion value Nw in step S32. In this case, the calculator 62 uses the weight Weight in calculating the weight conversion value Nw in step S22 of FIG. Similarly, the calculator 62 may update the occupied area Area without updating the dimension conversion value Na in step S34. In this case, the calculator 62 uses the occupied area Area in calculating the dimension conversion value Na in step S23 of FIG.

As described above, in the first embodiment, when the target of use is the self-propelled device 6, the converted number of people of the target of use calculated based on the actual weight Weight and the occupied area Area of the self-propelled device 6 With N, the determination unit 112 specifies the number of users npsg. Therefore, the determination unit 112 can accurately calculate the total value of the number of users npsg on each floor from the departure floor to the destination floor to be used by the elevator, and assign You can decide whether to accept or not.

(Modification)
In the first embodiment, the case where the self-propelled device 6 calculates the converted number of people N based on the weight Weight and the occupied area Area has been described, but it is not limited to this case. The calculation unit 62 may calculate the converted number of people N using either the weight Weight or the occupied area Area.

When calculating the dimension conversion value Na, the calculation unit 62 uses, instead of the above-described occupied area Area, the horizontal dimension of the utilization target as the horizontal dimension, which is the dimension in one direction when the utilization target is viewed in plan. A vertical dimension, which is a dimension substantially perpendicular to the one direction, may be used. Alternatively, the calculator 62 may use a diagonal line of a quadrangle formed by the horizontal dimension and the vertical dimension.

Further, the user number npsg of users may not be uniformly set to 1, and a predetermined number may be assigned to, for example, wheelchair users. In addition, when a user makes an allocation request as a group of a plurality of users, the number of users in the group may be used as the number of users npsg.

[Embodiment 2]
FIG. 8 is a diagram showing an example of the configuration of the elevator management device 51 according to the second embodiment. The control unit 11 of the elevator management device 51 has a calculation unit 115 . In the elevator management device 51 according to the second embodiment, the calculator 115 calculates the weight conversion value Nw and the dimension conversion value Na.

In the registration information table 661 of the storage unit 66 of the self-propelled device 6 of the second embodiment, instead of the items of the converted number of people N, the weight conversion value Nw, and the dimension conversion value Na of the registration information table 661 of the first embodiment, Items of weight (kg) and occupied area Area (m ² ) are stored. An example of the registration information table 661 is shown in Table 3 below.

The registration information table 661 according to the second embodiment has items such as usage target attribute, registration source ID, departure floor, destination floor, weight (kg), occupied area Area (m ² ), and optimum car number. The columns of usage target attribute, registration source ID, departure floor, destination floor, and optimum car number are the same as the columns of usage target attribute, registration source ID, departure floor, destination floor, and optimum car number of the registration information table 661 of the first embodiment. Content is stored. The weight calculated by the calculator 62 of the self-propelled device 6 is stored in the column of "Weight (kg)". Each time the calculation unit 62 calculates the weight, it updates the value in the column of "Weight (kg)". The column of “occupied area Area (m ² )” stores the occupied area Area calculated by the calculator 62 . Each time the calculating unit 62 calculates the occupied area Area, it updates the value in the column of "occupied area Area (m ² )".

For example, Table 3 shows the case where the self-propelled device 6 whose registration source ID is "ROBOT-003" moves from the "2nd" floor with a load and delivers the load on the "9th" floor. indicates The weight of the self-propelled device 6 is 14 kg, and the load of 36 kg is loaded, so the weight, which is the total weight, is 50 kg. The occupied area of the self-propelled device 6 itself is 0.18 m ² , but the occupied area is increased to 0.25 m ² because it is loaded with cargo. The weight and occupied area of the self-propelled device 6 change according to the work content and the like, and are updated each time. The elevator management device 51 calculates the weight conversion value Nw and the dimension conversion value Na based on the weight Weight and the occupied area Area obtained from the self-propelled device 6 . The elevator management device 51 specifies the converted number of people N based on the calculated weight conversion value Nw and dimension conversion value N, specifies the number of users npsg based on the converted number of people N, and determines whether or not to allocate to the car.

(Processing performed by elevator management device 51)
FIG. 9 is a flow chart showing the procedure for calculating the weight conversion value Nw and the dimension conversion value Na by the control unit 11 of the elevator management device 51 and storing the number of users npsg in the registration information table 121. As shown in FIG.

The management unit 111 determines whether or not the allocation request data transmitted by the destination floor call registration device 2 or the self-propelled device 6 is received via the communication control unit 114 (step S41). In the second embodiment, the allocation request data includes the attributes of the use object, the ID of the registration source, the departure floor, the destination floor, the weight of the self-propelled device 6 at the time of the allocation request, and the weight of the self-propelled device 6 at the time of the allocation request. Occupied area Area is included. Here, the weight Weight and the occupied area Area at the time of the allocation request refer to the weight Weight and the occupied area Area stored in the registration information table 661 at the time of the allocation request. When determining that allocation request data has not been received (step S41: NO), the management unit 111 repeats step S41.

When determining that the allocation request data has been received (step S41: YES), the determination unit 112 determines whether or not the attribute to be used is the self-propelled device 6 (step S42).

When the calculation unit 115 determines that the attribute to be used is the self-propelled device 6 (step S42: YES), the calculation unit 115 calculates the weight conversion value Nw (step S43). As an example, the calculation unit 115 substitutes the weight included in the allocation request data into the above equation (1) to calculate the weight conversion value Nw.

The calculation unit 115 also calculates the dimension conversion value Na (step S44). As an example, the calculation unit 115 substitutes the occupied area Area included in the allocation request data into the above equation (2) to calculate the dimension conversion value Na. Note that steps S43 and S44 may be performed in reverse order, or may be performed in parallel.

The calculator 115 determines whether weight conversion value Nw>dimension conversion value Na (step S45). When determining that the weight conversion value Nw>the dimension conversion value Na (step S45: YES), the calculation unit 115 sets the weight conversion value Nw as the number of people to be converted N (step S46).
If the calculation unit 115 determines that the weight conversion value Nw is not greater than the size conversion value Na, that is, the weight conversion value Nw≦the size conversion value Na (step S45: NO), the calculation unit 115 sets Na as the number of people to be converted N (step S47).
After that, the determining unit 112 specifies the converted number of people N as the number of users npsg (step S48).
On the other hand, when the determining unit 112 determines that the attribute to be used is not the self-propelled device 6, that is, is the user (step S42: NO), it sets the number of users npsg to 1 (step S49). After that, the control unit 11 performs the processing of steps S6 to S12 in the flow chart of FIG.

(Processing performed by self-propelled device 6)
FIG. 10 is a flowchart showing an example of processing by the control unit 60 of the self-propelled device 6. As shown in FIG.

The management unit 61 determines whether or not to use the elevator 4 (step S51). When the management unit 61 determines not to use the elevator 4 (step S51: NO), it repeats step S51.

When the management unit 61 determines that the elevator 4 is to be used (step S51: YES), the calculation unit 62 calculates Weight and stores it in the registration information table 661 (step S52). For example, when the self-weight is A kg and a transport instruction to transport a load of B kg is received from the self-propelled device management device 5, the calculation unit 62 sets (A+B) kg as the weight Weight. The calculation unit 62 may use the weight obtained by using the weight scale installed on the floor of the building with the self-propelled device 6 as the weight. The calculation unit 62 calculates weight at predetermined time intervals in advance and stores it in the registration information table 661. When it is determined in step S51 that the elevator 4 is to be used, the calculation unit 62 reads out the registration information table 661 and calculates the weight. may be obtained.

The calculator 62 calculates the occupied area Area and stores it in the registration information table 661 (step S53).
