Description

The present invention relates to a group management control device for managing the operation of a plurality of elevators, and a group management control method.

Conventionally, if the number of people on the upper floors, where the observatory and the restaurant area are located, is large, it is easy for the lower floors to be full. If the number of passengers on the upper floors is not interrupted, the passengers will board the car that arrived after receiving the call for the landing on the upper floors again, and the car will be full. Therefore, the crowded passages on the lower floors occur continuously, and the time when the elevator does not arrive may be prolonged. In response to the problem of prolonged waiting time for users on the lower floors, a technique for reducing the waiting time for users on the lower floors has been proposed.

For example, in the invention described in Patent Document 1, when an elevator is assigned to a new hall call (new landing call), when the estimated arrival time of each elevator is calculated, it is assumed that the elevator provides a plurality of cycle services for a plurality of cycles. The arrival time is predicted and calculated, and the results are recorded in the predicted arrival time table. Then, in the invention described in Patent Document 1, a new hall call is selectively assigned to the elevator that can be serviced earliest by using the predicted arrival time table.

In Patent Document 1, "By registering the predicted arrival times for a plurality of cycles in the arrival prediction time table as described above, the optimum call allocation selection can be performed even in a time zone where traffic demand is high. It is possible to prevent the service level of the elevator from deteriorating and to realize control that does not make the hall waiters feel long waiting. "

Japanese Unexamined Patent Publication No. 8-119545

However, the technique described in Patent Document 1 is to provide a service to the registered floor of a registered call where a full passage occurs by dividing the service floor (setting an express zone), and the service is provided by dividing the express zone. There will be a floor where the price drops.

The present invention has been made in consideration of the above situation, and the long waiting time of the user of the registered floor of the registered call where the full passage occurs without dividing the service floor (setting the express zone). The purpose is to suppress the formation.

The group management control device of one aspect of the present invention includes a landing call information collecting unit that collects landing call information from a landing call generator that is provided on each of a plurality of floors and generates a landing call, and an operation status of a plurality of cars. Based on the landing call information and car information for each of the car information collection department and multiple cars, each car will be a new or registered landing at least after a new landing call is made. It is provided with an allocation car selection unit that calculates an allocation evaluation value that reflects the estimated time to arrive at the registered floor of the call and selects a car to be assigned to a new landing call based on the allocation evaluation value.
If there is a registered floor for a registered landing call that is expected to be full when a new landing call occurs, the above allocation car selection unit will register the landing call for which the car has already been registered. As an estimated time to arrive at the floor, after a new landing call is made, the car passes through the registered floor of the registered landing call in the first lap, and then the registered landing call is made on the second lap. The estimated time to arrive at the registered floor is calculated, and the estimated time for the second lap is reflected in the allocation evaluation value of the corresponding car.

According to at least one aspect of the present invention, it is possible to suppress the prolongation of the waiting time of the user of the registered floor of the registered call where the full passage occurs without dividing the service floor (setting the express zone). .. Issues, configurations and effects other than those described above will be clarified by the description of the following embodiments.

<1. One Embodiment>
[Overall configuration of group management elevator system]
FIG. 1 is an overall configuration diagram showing an example of a group management elevator system according to an embodiment of the present invention.
The group management elevator system 3 installed in the building is installed in, for example, an elevator control device 1 installed in an elevator machine room (not shown) and a hoistway (not shown), and the operation is managed by the elevator control device 1. It is equipped with three cars 41 to 43. Unit numbers 1 to 3 are assigned to the cars 41 to 43 in order.

In addition, the group management elevator system 3 has a landing call button 10, a hall lantern (reservation light) 91-93, and a holder 101-103 for each service floor (the 9th floor is illustrated in FIG. 1) of the cars 41 to 43. And. In the following description, when the cars 41 to 43 and the hold doors 101 to 103 are not distinguished, they may be referred to as "car" and "hold door" without reference numerals, respectively. Further, in the present embodiment, the number of cars is set to 3, but the number of cars may be a plurality of cars.

In the car 41 of the first machine, an information terminal device 51 for registering the destination floor by the user and a car position display device 61 for displaying the current position of the car 41 are installed. At the lower part of the floor surface of the car 41, a load sensor 71 that detects the load of the user who got into the car 41 is installed. Further, in the car 42 of the second unit, an information terminal device 52 for the user to register the destination floor and a car position display device 62 for displaying the current position of the car 42 are installed. At the lower part of the floor surface of the car 42, a load sensor 72 that detects the load of the user who got into the car 42 is installed. Similarly, in the car 43 of Unit 3, an information terminal device 53 for registering the destination floor by the user and a car position display device 63 for displaying the current position of the car 43 are installed, and the lower part of the floor surface of the car 43 is installed. A load sensor 73 that detects the load of the user who got into the car 43 is installed in the car 43.

The landing call button 10 is an example of a landing call generator. The landing call button 10 is installed near the landing on the service floor, and a push button type operator is used as an example. The landing call button 10 includes an upper button that is operated when the user wants to move to the upper floor and a lower button that is operated when the user wants to move to the lower floor. Then, when the user operates the landing call button 10, the landing call button 10 generates a landing call signal and a landing call is generated on the corresponding floor. In FIG. 1, it is assumed that the user operates the landing call button 10 to register the landing call in the elevator control device 1.

The hall lanterns 91 to 93 are provided on the hold doors 101 to 103 of the landing on each floor, which is the service floor of the cars 41 to 43, and are lit by a signal from the unit control devices 31 to 33, and the traveling directions of the cars 41 to 43. To inform the user. The whole lanterns 91 to 93 may display only the upward and downward directions, or may display the current location of the cars 41 to 43. The hold doors 101 to 103 are provided at the entrances and exits to the cars 41 to 43 at the landing on each floor which is the service floor of the cars 41 to 43.

The elevator control device 1 includes a group management control device 2 and the same number of unit control devices 31 to 33 as the three cars 41 to 43. The group management control device 2 selects one car assigned to the landing call generated by the landing call button 10 from the cars 41 to 43. Then, the group management control device 2 controls the raising and lowering of the cars 41 to 43, the display of the car position display devices 61 to 63, the display of the hall lanterns 91 to 93, and the like through the unit control devices 31 to 33.

The unit control devices 31 to 33 transmit the car information to the car information collecting unit 22. In the following description, when the unit control devices 31 to 33 are not distinguished, they are referred to as "unit control devices" without reference numerals.

The group management control device 2 includes a landing call information collection unit 21, a car information collection unit 22, a traffic information detection unit 23, an arrival prediction time table creation unit 24, a occupancy determination unit 25, and an allocation car selection unit 26. I have.

The landing call information collecting unit 21 collects landing call information from the landing call signal generated by the user operating the landing call button 10. The landing call information includes registered floor information indicating the floor on which the landing call has occurred, and desired movement direction information indicating the desired movement direction. The registered floor information is information indicating the floor (registered floor) on which the landing call button 10 operated by the user is installed. For example, it is found from the registered floor information that the registered floor is the lobby floor. Further, the desired movement direction information is information generated by the user by operating the landing call button 10 to indicate the desired movement direction of the user boarding from the registered floor. Then, the landing call information collected by the landing call information collecting unit 21 is sent to the traffic information detecting unit 23 and the arrival prediction time table creating unit 24.

The car information collecting unit 22 collects car information of each car 41 to 43 transmitted from the unit control devices 31 to 33. The car information includes, for example, the position and moving direction of the cars 41 to 43 transmitted from the unit control devices 31 to 33, and the load (fullness or fullness) of the user in the cars 41 to 43 obtained from the load sensors 71 to 73. Information on the operating status of the car, such as congestion level), is included. Then, the car information of the cars 41 to 43 collected by the car information collecting unit 22 is sent to the traffic information detecting unit 23, the arrival prediction time table creating unit 24, and the occupancy determination unit 25.

The traffic information detection unit 23 is based on the landing call information collected by the landing call information collecting unit 21 and the car information of the cars 41 to 43 collected by the car information collecting unit 22, and is used by the user of the group management elevator system 3. Detect traffic information. Then, the traffic information detected by the traffic information detection unit 23 is sent to the arrival prediction time table creation unit 24.

The traffic information detection unit 23 is a learning system, and can recognize the current traffic status from the daily operation status (information on the operation status) of the cars 41 to 43. The traffic information detection unit 23 learns the traffic situation based on the car usage information such as the car position and the number of passengers getting on and off and the destination floor information, and determines what kind of driving program is suitable at that time. Therefore, from the car information (and the number of people getting on and off by floor indicating the flow of people in the building, which is separately input from an external device), it is possible to determine whether it belongs to one of the characteristic modes indicating the typical traffic conditions in the building. to decide.

The feature mode indicates the state of the traffic condition divided by a certain number based on the traffic information of the downhill and the uphill. Normally, in the case of an office building, a traffic situation with a small number of people getting on and off is called off-peak, a traffic situation with a large number of people getting on and off is called an up-peak, and a traffic situation with a large number of people getting on and off is called a down-peak. In addition, the feature mode has features depending on the nature of the building, and new features may be extracted from the collected traffic conditions. When a new feature is extracted, the traffic information detection unit 23 generates and registers it as a feature mode peculiar to this building, and learns the tendency of changes in other feature modes.

The arrival prediction time table creation unit 24 generates a new landing call based on the landing call information, the car information of the cars 41 to 43, and the traffic information of the user in the building detected by the traffic information detection unit 23. An arrival prediction time table (see FIG. 4) that stores information on the predicted time of the first lap and the predicted time of the second lap until each car 41 to 43 arrives at each floor is created. The arrival prediction time table creation unit 24 predicts the arrival time of each floor every time a new landing call occurs or periodically, and updates the information in the arrival prediction time table with the latest arrival prediction time information. In this estimated arrival time table, at least after a new landing call is generated, each car 41 to 43 arrives at each registered floor of the new landing call (personal call) and the registered landing call (other person's call). It suffices to include information on the predicted time of the first lap and the predicted time of the second lap. Then, the arrival prediction time table (or each information stored in the arrival prediction time table) created by the arrival prediction time table creation unit 24 is sent to the occupancy determination unit 25 and the allocation car selection unit 26.

The occupancy determination unit 25 determines whether or not the occupancy is predicted when the occupants 41 to 43 reach the registered floor of the landing call based on the vehicle information of the casks 41 to 43 and the arrival prediction time table. For example, the fullness determination unit 25 calculates the full load state of the car 2 from the measurement result of the load sensor by calculating what percentage of the maximum load (load at the time of fullness) is currently applied to the floor of the car. Can be detected. When the threshold value for determining that the car is full is 100% (or 90% with a margin), and the load measured by the load sensor exceeds 100% (or 90%) of the maximum load, the car It is judged that the inside is full. The threshold value may be the maximum load [kg] when the vehicle is full.

Further, as a method of determining the full state in the car, a camera (surveillance camera) (not shown) that photographs the inside of the car 2 can also be used. Image processing (for example, human recognition processing) may be performed on the image captured by the camera, and when the result of the image processing satisfies a predetermined condition, it may be determined that the car is full. As a person recognition process, for example, there is a technique of detecting a person by extracting a person's face from an image. In addition, when there is no or little empty space in the car due to not only people but also objects such as luggage and wheelchairs, it may be determined that the car is full.

When a new landing call is generated, the allocation car selection unit 26 registers new and already registered cars for each of the cars 41 to 44 based on the landing call information and the car information, at least after the new landing call is generated. Calculate the allocation evaluation value that reflects the estimated time to arrive at the registered floor of each landing call. In the car of the unit having the minimum allocation evaluation value in the present embodiment, the total waiting time of the user until the car arrives at the registration floor of the new and registered landing call is the minimum.

For example, the allocation car selection unit 26 is based on the arrival prediction time table created (updated) by the arrival prediction time table creation unit 24 and the determination result (fullness or congestion degree) of the occupancy determination unit 25, and the baskets 41 to 43. The allocation evaluation value is calculated for each. Then, the allocation car selection unit 26 selects a car to which a new landing call is assigned from the cars 41 to 43 based on the allocation evaluation values of the cars 41 to 43.

At this time, if there is a registered floor of a registered landing call that is expected to be full when a new landing call occurs, the allocation car selection unit 26 will use the car to be a registered landing. The estimated arrival time for the second lap is calculated as the estimated time to arrive at the registered floor of the call. The estimated arrival time for the second lap is the registered floor of the registered landing call on the second lap after the car passes through the registered floor of the registered landing call in the first lap after the new landing call is generated. It is the estimated time to return to. The allocation car selection unit 26 reflects the estimated arrival time of the second lap in the allocation evaluation value of the corresponding car.

In this way, the allocation car selection unit 26 is the registration floor of the already registered boarding call, which is predicted to pass full when a new boarding call occurs, based on the determination result of the fullness determination unit 25. If it is determined that there is, the waiting time evaluation value for the registered landing call based on the estimated time of the second lap until the corresponding car stored in the arrival estimated time table arrives at each floor (Fig. 6). Calculate the other person's waiting time evaluation value). Then, the allocation car selection unit 26 reflects the waiting time evaluation value in the allocation evaluation value.

Then, the allocation car selection unit 26 shortens the total waiting time based on the determination result of the fullness determination unit 25 and the estimated time until the car stored in the arrival prediction time table arrives at each floor. Assign a new landing call to one car selected from multiple cars.

When a new landing call is assigned to one car, the unit control device controls the operation of the car so that the car to which the landing call is assigned moves to the registered floor. A series of processes performed by the allocation car selection unit 26 are performed according to the flowcharts shown in FIGS. 6 and 7 described later. The allocation car selection unit 26 described above may have the functions of the traffic information detection unit 23, the arrival prediction time table creation unit 24, and the occupancy determination unit 25.

Further, in the present embodiment, the landing call button 10 is used as the landing call generator, but the present invention is not limited to this example. For example, a destination floor registration device may be used as a landing call generator. The destination floor registration device is a device installed at the landing on each floor that serves as the service floor of the car, and the user inputs the destination floor to perform call registration. When the user performs call registration with the destination floor registration device, the landing call and the destination floor information are transmitted to the landing call information collecting unit 21. The destination floor registration device is provided with a display unit, and the car number assigned by the group management control device 2 is displayed on the display unit. Therefore, after registering the call with the destination floor registration device, the user confirms the machine number displayed on the display unit and waits for the car to arrive in front of the car with the machine number.

[Hardware configuration of each device of elevator control device 1]
Next, the hardware configuration of the computer C constituting each device of the elevator control device 1 will be described.
FIG. 2 is a block diagram showing a hardware configuration example of computer C.

The computer C is hardware used as a so-called computer. The computer C includes a CPU (Central Processing Unit) C1, a ROM (Read Only Memory) C2, and a RAM (Random Access Memory) C3, which are connected to the bus C4, respectively. Further, the computer C includes a non-volatile storage C5 and a network interface C6.

The CPU C1 reads the program code of the software that realizes each function according to the present embodiment from the ROM C2 and executes it. Variables, parameters, etc. generated during the arithmetic processing are temporarily written in the RAM C3. The operations of the group management control device 2 and the unit control devices 31 to 36 are executed by, for example, the CPUC1.

As the non-volatile storage C5, for example, HDD (Hard Disk Drive), SSD (Solid State Drive), flexible disk, optical disk, optical magnetic disk, CD-ROM, CD-R, magnetic tape, non-volatile memory and the like are used. Be done. In this non-volatile storage C5, in addition to the OS (Operating System) and various parameters, a program for operating the computer C is recorded. The ROM C2 and the non-volatile storage C5 record programs and data necessary for the CPU C1 to operate, and are an example of a computer-readable non-transient recording medium that stores a program executed by the computer C. Used as. Therefore, this program is permanently stored in the ROM C2 and the non-volatile storage C5. The arrival prediction time table created and updated by the arrival prediction time table creation unit 24 is constructed in, for example, the non-volatile storage C5.

For the network interface C6, for example, a NIC (Network Interface Card) or the like is used, and various data can be transmitted and received between the devices via a LAN (Local Area Network), a dedicated line, or the like.

[Example of car operation by group management control device]
3 to 5 are diagrams for explaining an operation example of the car by the group management control device 2. 3 to 5 show an operation example of Unit 1 (car 41) in a building where a car is operated between the 1st floor and the 10th floor.

(Example of car position and landing call)
FIG. 3 is an explanatory diagram showing an example of the car position and landing call of Unit 1. In FIG. 3, the current position of the car 41 is on the 7th floor, and the current moving direction (nominal direction) of the car 41 is downward.
When the user operates the lower button of the landing call button 10 installed at the landing on the 9th floor, the landing call information is collected by the landing call information collecting unit 21, and the landing call 200 (downward black-painted triangle) is collected on the 9th floor. ) Has occurred and the desired movement direction is downward is detected and registered. Further, in FIG. 3, when the landing call 200 is generated, the landing calls 201 and 202 (downward triangles) whose desired movement direction is downward have already been generated on the 4th and 3rd floors. In the following description, the landing call 200 newly generated by the user himself / herself is referred to as "new call" or "personal call", and the landing calls 201 and 202 already registered by another person are referred to as "registered call" or "other person's call". Also called.

(Example of estimated time)
FIG. 4 is an explanatory diagram showing an example of the estimated time until the car 41 stored in the estimated arrival time table arrives at each floor. In FIG. 4, in order to make the explanation easy to understand, the travel time to the adjacent floor directly below and the floor directly below is uniformly set to 5 seconds. In FIG. 4, the car 41 located on the 7th floor is set as the starting point (0 seconds) of the predicted time. The estimated time for the car 41 to depart from the 7th floor, move downward (DN) and arrive at the 1st floor is 30 seconds, then change direction on the 1st floor and move upward (UP) to the 10th floor. The estimated time to arrive at is 75 seconds, and the estimated time to change direction on the 10th floor and return to the original 7th floor (time required for one lap) is 90 seconds. Furthermore, the estimated time to reach the 1st floor on the 2nd lap is 120 seconds, the estimated time to change direction on the 1st floor and arrive at the 10th floor is 165 seconds, and the estimated time to arrive on the 10th floor is changed to the 8th floor. The time to complete is 175 seconds.

(Example of car operation)
5A and 5B are explanatory views showing an operation example of the car 41, FIG. 5A shows an operation example of the conventional car 41, and FIG. 5B shows an operation example of the car 41 according to the embodiment of the present invention. In FIGS. 5A and 5B, the car position and the landing call are the same as those shown in FIG.

As shown in FIG. 5A, conventionally, the car 41 moving downward near the 7th floor has the car 41 even if the registered call 201 and the registered call 202 are registered on the 4th and 3rd floors. When arriving at the 4th and 3rd floors, the car 41 passes through the 4th and 3rd floors (passes full) because the car is full. Then, the car 41 goes around the hoistway and arrives at and stops at the 9th floor where the new call 200 is registered. For this reason, users of the registered calls 201 and 202 (Fig. 3) on the 4th and 3rd floors will find that the car 41 passes on the first lap and the car 41 is full on the upper floors on the second lap. I can't get in the car 41. Therefore, users on the lower floors (near the end floors) such as the 4th and 3rd floors have to wait for a long time until the congestion in the car 41 is alleviated. For example, the estimated arrival times on the 4th and 3rd floors on the second lap are 105 seconds and 110 seconds, and the waiting time until the users on the 4th and 3rd floors can get in the car is further longer.

On the other hand, in the present embodiment, when the car 41 moving downward near the 7th floor arrives at the 4th and 3rd floors where the registered calls 201 and 202 are located, the inside of the car may become full. If predicted, the car 41 will be fully occupied on the 4th and 3rd floors on the first lap. Here, another unit is assigned to the user on the 9th floor with the new call 200, and the car 41 passes through the 9th floor. As a result, the degree of congestion in the car will be eased, so that the car 41 will not be full when it arrives on the 4th and 3rd floors on the second lap, and users with registered calls will be allowed to board the car. Can be done. In this way, Unit 1 (basket 41) can suppress the allocation of landing calls other than the registered calls 201 and 202, save the registered calls 201 and 202, and significantly reduce the waiting time of the user.

[Process to assign a new landing call to the car]
Hereinafter, the selection process of a plurality of cars performed by the group management control device 2 will be described.
FIG. 6 is a flowchart showing an example of a process of allocating a new landing call to any of a plurality of cars. In the following process, it is assumed that the user has registered the landing call using the landing call button 10.

First, when the user presses the upper button or the lower button of the landing call button 10 on any floor, the landing call button 10 generates a landing call signal. The landing call information collecting unit 21 collects landing call information from the landing call signal generated by the landing call button 10 (S1). The landing call information includes information on the floor (registered floor) where the landing call occurred and the user's desired movement direction.

In addition, the car information collecting unit 22 collects car information from the unit control devices 31 to 33 (S2). As described above, the car information includes, for example, the position and moving direction of the cars 41 to 43 transmitted from the unit control devices 31 to 33, and the user in the cars 41 to 43 obtained from the load sensors 71 to 73. Includes information about the operating status of the car, such as load (fullness or congestion).

Next, the traffic information detection unit 23 uses the landing call information collected by the landing call information collecting unit 21 and the car information of the cars 41 to 43 collected by the car information collecting unit 22 to determine the traffic of the user in the building. Information is detected (S3).

Next, the arrival prediction time table creation unit 24 creates an arrival prediction time table (see FIG. 4) based on the landing call information, the car information of the cars 41 to 43, and the traffic information of the users in the building (S4). ). As described above, the arrival prediction time table stores information on the predicted time of the first lap and the predicted time of the second lap from the occurrence of a new landing call to the arrival of each car 41 to 43 on each floor. Has been done.

Next, the occupancy determination unit 25 determines whether or not the occupancy is predicted when the occupants 41 to 43 reach the registered floor of the landing call based on the occupancy information of the casks 41 to 43 and the arrival prediction time table. Then, the determination result is sent to the allocation car selection unit 26 (S5).

Next, the allocation car selection unit 26 allocates each unit (cars 41 to 43) based on the arrival prediction time table created (updated) by the arrival prediction time table creation unit 24 and the determination result of the occupancy determination unit 25. The evaluation value is calculated (S6). For example, the allocation car selection unit 26 calculates the allocation evaluation value for each unit based on the person's waiting time evaluation value (waiting time for a new call), the elevator state evaluation value, the other person's waiting time evaluation value, and the like.

In the figure, it is generally described as Unit n, but in this embodiment, since there are three elevators identified by Units 1 to 3 as shown in FIG. 1, n = 3 and assigned. The car selection unit 26 calculates three allocation evaluation values. The allocation car selection unit 26 calculates the allocation evaluation value by adding up the evaluation values obtained for each unit. The allocation evaluation value may be a value calculated by the allocation car selection unit 26 by multiplying each evaluation value.

The personal waiting time evaluation value is a value that evaluates the waiting time from the floor (position) where the car is currently moving or stopped until the car arrives at the registered floor of the newly registered landing call (new call). Is. If the waiting time is short, the waiting time evaluation value is small, and if the waiting time is long, the waiting time evaluation value is large.

The elevator state evaluation value is a value that evaluates factors that affect the waiting time such as deceleration of the car and the open state of the door. For example, when the car is moving or when the door is closed and the car can start moving immediately, the elevator state evaluation value becomes small. On the other hand, when the car is decelerating or stopped, or when the door is open, the elevator state evaluation value becomes large. The load information of the car collected by the car information collecting unit 22 may be reflected in the elevator state evaluation value. For example, if it can be confirmed from the load of the users in the car that the number of users in the car is large, it is expected that it will take time for the users to get off the vehicle before arriving at the registered floor. Becomes larger.

The other person waiting time evaluation value is an evaluation value of the waiting time from the floor where the car is currently moving or stopped until the car arrives at the registered floor of the already registered landing call (registered call). If the waiting time is short, the waiting time evaluation value is small, and if the waiting time is long, the waiting time evaluation value is large. Based on the determination result of the fullness determination unit 25, the allocation car selection unit 26 is a registered floor of the already registered landing call (for example, FIG. 5) in which it is predicted that the car will pass full when a new landing call is generated. If it is determined that there are 3rd floor and 4th floor), the waiting time until the car arrives at the registered floor of the registered landing call on the second lap is evaluated as this other person's waiting time evaluation value. calculate. The method of calculating the other person's waiting time evaluation value will be described in detail with reference to FIG.

Here, the calculation process of the other person's waiting time evaluation value will be described with reference to FIG. 7. FIG. 7 is a flowchart showing an example of the process of calculating the other person's waiting time evaluation value.

First, the allocation car selection unit 26 determines whether or not there is another person's call (registered call) based on the landing call information (S11), and if there is no other person's call (NO in S11), the other person's call The other person's waiting time evaluation value is calculated in consideration of the information of none (S15). After the process of step S15 is completed, the process returns to the process of step S6 of FIG.

Next, when the allocation car selection unit 26 has a call to another person (YES in S11), whether or not the registration floor for the call to another person is a floor that is expected to pass through based on the determination result of the fullness determination unit 25. (S12). Here, if the registered floor for calling others is a floor that is expected to pass through (YES in S12), the allocation car selection unit 26 considers up to the estimated time of the second lap of the arrival estimated time table. Calculate the waiting time for others (S13). On the other hand, if the registered floor for calling another person is not a floor that is expected to pass through (NO in S12), the allocation car selection unit 26 calculates the waiting time for another person based on the estimated time of the first lap of the estimated arrival time table. (S14).

Then, after the processing of step S13 or step S14 is completed, the allocation car selection unit 26 calculates the other person waiting time evaluation value based on the calculated other person waiting time (S15). After the process of step S15 is completed, the process returns to the process of step S6 of FIG.

Next, the allocation car selection unit 26 compares the allocation evaluation values for each unit, and assigns the landing call to the car with the smallest allocation evaluation value (S7). If there is a car that is expected to pass the registered floor of the already registered landing call when a new landing call occurs, wait for another person considering the estimated time of the second lap in the allocation evaluation value. The time evaluation value is included, and the allocation evaluation value becomes large. As a result, the allocation car selection unit 26 does not allocate a new landing call to the corresponding car (Unit 1 in this embodiment). Then, the allocation car selection unit 26 allocates a new landing call to a car (Unit 2 or Unit 3 in the case of FIGS. 3 to 5) that is different from the corresponding car.

Then, the allocation car selection unit 26 transmits an allocation signal indicating that the landing call has been assigned to the unit control device corresponding to the car to which the landing call has been assigned (S8). As a result, the car to which the landing call is assigned is driven by the unit control device in a predetermined operation pattern.

In one embodiment described above, the allocation car selection unit 26 evaluates the new call and the waiting time for the registered call affected by the new call when performing the normal allocation evaluation. On the other hand, when the allocation car selection unit 26 has a registration floor of the registered call that is expected to be full, the arrival prediction time table is set even before the car passes the registration floor of the registered call. Calculate the other person's waiting time evaluation value using the estimated arrival time of the second lap registered in. As a result, the present embodiment suppresses the allocation of new cars to floors other than the registered floors of the registered calls, and preferentially services (stops the cars) to the registered floors of the already registered calls that have passed the full capacity. Can be done. As described above, in the present embodiment, when there is a floor of a registered call that is predicted to pass full when a new call occurs, the other person's waiting time evaluation calculated using the estimated arrival time of the second lap is used. Reflect the value in the allocation evaluation value. Therefore, in the present embodiment, it is possible to suppress the prolongation of the waiting time of the user of the registered floor of the registered call due to the full passage without dividing the service floor (setting the express zone) as in the conventional case. ..

In the above-described embodiment, the priority of the evaluation value of the specific item in the allocation evaluation value is set high, and the machine to be assigned to the landing call is determined based on the magnitude of the evaluation value of the specific item. May be good. For example, the landing call may be assigned to the unit having the lowest evaluation value of waiting time for others.

<2. Modification example>
In one embodiment described above, when it is predicted that the car will pass through the registered floor of the registered call, the estimated arrival time of the second lap will be used to calculate and allocate the waiting time evaluation value for others. Although it is reflected in the evaluation value, the estimated arrival time after the third lap may be used. For example, register the estimated arrival time of each floor up to the third lap in the estimated arrival time table, calculate the other person's waiting time evaluation value using the estimated arrival time of the third lap, and reflect it in the allocation evaluation value. May be good. This is effective when there is a popular area such as an observatory on the upper floors, and a car with a large number of users constantly descending from the upper floors, and it is effective for transporting users on the upper floors and on the lower floors. It is possible to balance the waiting time of the user.

Furthermore, the present invention is not limited to the above-described embodiments, and it goes without saying that various other application examples and modifications can be taken as long as they do not deviate from the gist of the present invention described in the claims. ..

For example, the above-described embodiment describes the configuration of the device and the system in detail and concretely in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to the one including all the components described. In addition, it is possible to replace a part of the configuration of one embodiment with a component of another embodiment. It is also possible to add components of another embodiment to the configuration of one embodiment. It is also possible to add, delete, or replace other components with respect to a part of the configuration of each embodiment.
