Description

The present invention relates to elevator control technology.

In recent years, due to epidemics of infectious diseases such as coronaviruses, there has been an increasing demand for alleviating congestion (that is, a dense state) of users in elevator cars as much as possible. In order to meet such a demand, the present inventor set the upper limit of the boarding rate of a car (that is, the upper limit of the number of hall calls allocated to the car) to a small value, for example, about 20%. The idea is to limit the number of users who can ride in the car to alleviate the congestion in the car.

In addition, as a technique for changing the upper limit value of the occupancy rate, the present inventor has found that when a user with a predetermined attribute (for example, a disabled person) calls for a hall, the car in which the user rides Japanese Patent Application Laid-Open No. 2002-200001 proposes setting the upper limit of the passenger rate to a value smaller than the value during normal times so that the user can easily board the vehicle.

JP 2017-154839 A

However, when the upper limit value of the occupancy rate is set small, the transportation capacity of the elevator itself is reduced. For this reason, when the number of users increases (for example, when commuting time arrives, or when tenants move into buildings such as office buildings), the elevator itself will provide the necessary transportation capacity. Therefore, there arises a problem that the user has to wait for a long time at the boarding point.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a technology capable of alleviating congestion in a car while exerting a necessary transportation capacity in an elevator.

An elevator control device according to the present invention includes an acquisition processing unit and an update processing unit. The acquisition processing unit acquires the number of users in the building in which the elevator is installed. The update processing unit updates the upper limit value of the occupancy rate set for the car according to the number of users in the building acquired by the acquisition processing unit.

According to the above control device, it is possible to update the upper limit of the occupancy rate according to the number of users in the building so that the upper limit of the occupancy rate becomes smaller when the number of users in the building is small. Become. According to such control, when the number of users in the building is small, the congestion in the car is reliably alleviated by decreasing the upper limit value of the boarding rate.

In the above control device, the ratio of the number of users per unit time that can be transported in the car to the number of users in the building acquired by the acquisition processing unit is defined as the transportation capacity of the elevator, and the update processing unit calculates the value of the transportation capacity. The upper limit value of the boarding rate may be updated so that is equal to or greater than a predetermined value. According to this configuration, it is possible to update the upper limit value of the occupancy rate set for the car so that the target elevator can exhibit the required transportation capacity.

The elevator may have multiple cars. In this case, in the above control device, the update processing unit sets the upper limits of the occupancy rates of all the cars to zero or a value that can alleviate congestion in the cars as their initial values. In at least a part of the car, the upper limit value of the occupancy rate may be updated according to the number of users in the building acquired by the acquisition processing unit. As an example, the update processing unit can uniformly update the upper limit values of the occupancy rates set for all the cars using the same value. As another example, the update processing unit may update the upper limit value of the occupancy rate as follows.

The update processing unit updates the upper limit value of the boarding rate set in any one or some of the cars according to the number of users in the building, and When the upper limit of the rate reaches a predetermined value, the upper limit of the occupancy rate set for one or more cars is reduced according to the number of users in the building. You may update. According to this configuration, even if the number of users in the building increases, it is possible to maintain as many cars as possible while reducing congestion while exhibiting the necessary transport capacity in the target elevators.

Further, the update processing unit may maintain the initial value of the upper limit value of the occupancy rate for any one or some of the cars without updating. According to this configuration, even if the number of users in the building increases, it is possible to always leave a car whose congestion is alleviated.

The control device may further include a call registration processing unit that allocates a hall call to any one of the cars. Then, the call registration processing unit, when allocating a hall call to a car, sets the car in a congestion alleviation mode emphasizing the alleviation of congestion based on the upper limit of the occupancy rate set for the car. It may be notified to the user who called the platform whether the bus is operated in a mode that emphasizes transportation efficiency or in a transportation-oriented mode that emphasizes transportation efficiency. According to this configuration, the user can recognize in what transport mode the car in which he or she should board is operated by checking the notified information.

ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to relieve the congestion in a car, demonstrating a required transportation capacity in an elevator.

[1] Overall Configuration of Elevator FIG. 1 is a conceptual diagram showing the overall configuration of an elevator. FIG. 2 is a conceptual diagram showing the configuration of an elevator hall on a specific floor (a floor such as a lobby floor where the elevator can be used only after entering the building). In addition, in FIG. 2, the boarding point is indicated by symbol H. As shown in FIG. As shown in these figures, the elevator includes a car 100, a regulation device 101 (including an entrance regulation device 101A and an exit regulation device 101B), a security server 102, an elevator controller 103, and a group supervisory controller. 104 and. The group supervisory control device 104 is an embodiment of the control device according to the present invention. The configuration of each unit will be specifically described below. Although not particularly limited, FIG. 1 shows, as an example of an elevator, a configuration in which three cars 100 and two entrance regulation devices 101A and two exit regulation devices 101B are provided. .

<Regulation device>
The regulation device 101 is a device (such as a security gate) that regulates the passage of users. The regulation device 101 includes an entrance regulation device 101A and an exit regulation device 101B. Here, the entrance regulating device 101A and the exit regulating device 101B are devices that respectively regulate the entrance and exit of the elevator from the hall on a specific floor (see FIG. 2). Therefore, only users who are permitted to pass through these restricting devices 101 can pass through the entrance restricting device 101A and enter the hall, and by passing through the entrance restricting device 101A, they can use the elevator only after entering the building. becomes possible. Also, a user who is permitted to pass through the regulation device 101 can exit the hall through the exit regulation device 101B.

Device information Pd for identifying them is set in the entrance regulation device 101A and the exit regulation device 101B. Further, these regulation devices 101 are provided with a reading device 1 for reading information from a recording medium Q (IC card, magnetic card, etc.) possessed by a user. Here, the identification information Pi of the user who possesses the recording medium Q (unique information for identifying the recording medium Q, such as a unique ID) is recorded on the recording medium Q, and the reading device 1 identifies the recording medium Q from the recording medium Q. Read the information Pi.

The reading method of the recording medium Q by the reader 1 may be a contact type or a non-contact type that reads information by near field communication such as NFC (Near Field Communication). It is not limited. Further, the recording medium Q is not limited to a card-like one, and may be stick-like or chip-like. Alternatively, a mobile information terminal such as a smart phone capable of short-range communication (NFC, etc.) with the reading device 1 may be used as the recording medium Q. FIG.

The entrance regulation device 101A is further provided with a display device 2 for displaying information about the car 100 in which the user should ride. Information for identifying 100 (such as numbers and symbols; hereinafter, this information will be referred to as "car information Pg") is displayed. The display device 2 may also be provided in the exit regulation device 101B, and the display device 2 may display an exit time, a message, and the like.

The identification information Pi read by the reading device 1 of the regulation device 101 (entrance regulation device 101A and exit regulation device 101B) is used for security management in the building (authentication of the identification information Pi, etc.) executed by the security server 102. . Therefore, when the reading device 1 reads the identification information Pi, the regulation device 101 transmits the identification information Pi to the security server 102 (see FIG. 1). At this time, the restriction device 101 transmits the device information Pd of the restriction device 101 together with the identification information Pi to the security server 102 so that the security server 102 recognizes the location of itself, which is the source of the identification information Pi. Note that the regulation device 101 may transmit, as the device information Pd, to the security server 102 information identifying the reading device 1 provided therein (that is, the reading device 1 that has read the identification information Pi).

Then, the security server 102 authenticates the identification information Pi based on the information received from the regulation device 101, and permits the user to pass through the regulation device 101 only when the authentication is successful.

According to such a configuration, by counting the number of users who are permitted to pass through the entrance regulation device 101A, the number of users who have entered the hall (hereinafter referred to as "number of people Na") is obtained. can do. Also, by counting the number of users who are permitted to pass through the exit regulation device 101B, it is possible to obtain the number of users who have left the hall (hereinafter referred to as "number of exiters Nb"). By subtracting the number of exiting people Nb from the number of entering people Na, the number of users Nc who can use the elevator in the building (hereinafter referred to as "the number of users in the building Nc") can be grasped. .

Note that the restriction device 101 may have the functions of both the entrance restriction device 101A and the exit restriction device 101B (that is, the entrance restriction device 101A and the exit restriction device 101B are integrated).

<Security Server>
The security server 102 performs security management within the building by controlling, for each user, the regulation and permission of passage by the regulation device 101 (entrance regulation device 101A and exit regulation device 101B) (security management processing). Specifically, the security server 102 authenticates the identification information Pi transmitted from the regulation device 101 (authentication processing), and permits the user to pass through the regulation device 101 only when the authentication is successful. do. Further, when the security server 102 has successfully authenticated the identification information Pi, the security server 102 transmits information necessary for elevator control to the group supervisory control device 104 (transmission processing). Details of the security management process will be described below.

FIG. 3 is a flowchart showing security management processing executed by the security server 102. As shown in FIG. The security management process is started when the security server 102 receives information (identification information Pi and device information Pd) from the regulation device 101 (entrance regulation device 101A or exit regulation device 101B).

When the security management process is started, the security server 102 performs operation control (traffic regulation and permission, etc.) for the regulation device 101 that is the transmission source of the information (identification information Pi and device information Pd), and controls the regulation device 101. Based on the received device information Pd, it is specified which restriction device 101 is the transmission source so that information can be transmitted (specification processing, step S101).

Specifically, the security server 102 has device management data D1. FIG. 4A is a conceptual diagram showing an example of the device management data D1. In the device management data D1, device address Pa, attribute information Pb, and installation floor Fs are associated with each device information Pd. Here, the device address Pa may be the regulating device 101 identified by the device information Pd (the reading device 1 identified by the device information Pd). 101) and used for information transmission to the regulation device 101 (IP address, etc.). The attribute information Pb indicates whether the regulating device 101 identified by the device information Pd (which may be the reading device 1 identified by the device information Pd) is an entrance device provided on the entrance side of the hall, or This is information for specifying whether it is an exit device provided on the exit side of the hall. In FIG. 4A, "0" and "1" are used as the values of the attribute information Pb in order to distinguish between the entrance device and the exit device. The installation floor Fs is a floor where the regulation device 101 identified by the device information Pd (which may be the reading device 1 identified by the device information Pd) is installed.

Then, in the identification process (step S101), the security server 102 acquires the device address Pa and attribute information Pb corresponding to the received device information Pd from the device management data D1, thereby obtaining information (identification information Pi and device information Pd). specifies the restriction device 101 that is the transmission source of the

After that, the security server 102 authenticates the received identification information Pi (authentication process, step S102), and depending on whether the authentication is successful or not, the user identified by the identification information Pi is permitted to pass through the regulation device 101. judge whether or not the person is

Specifically, when the identification information Pi is successfully authenticated in step S102, the security server 102 determines that the user identified by the identification information Pi is permitted to pass through the regulation device 101. We judge that it is. On the other hand, if the authentication of the identification information Pi fails in step S102, the security server 102 determines that the user identified by the identification information Pi is not permitted to pass through the regulation device 101. I judge. In this way, it is determined whether or not each user is permitted to pass through the regulation device 101 based on the success or failure of the authentication of the user's identification information Pi.

Then, when the authentication of the identification information Pi is successful in step S102, the security server 102 executes the transmission process (step S103) described below, and then performs the restriction specified by the device address Pa acquired in step S101. By controlling the operation of the device 101, the gate is opened, thereby permitting the user to pass through the regulation device 101 (step S104A). The transmission process (step S103) described below may be performed after step S104A.

In the transmission process (step S103), the security server 102 transmits information necessary for elevator control to the group supervisory control device 104. FIG. Here, the necessary information depends on whether the value of the attribute information Pb acquired by the security server 102 in step S101 is "0" (entrance device) or "1" (exit device). different. A specific description will be given below.

In this embodiment, when the identification information Pi read by the entrance regulation device 101A is successfully authenticated by the security server 102, the group supervisory control device 104 performs call registration for the identification information Pi. That is, when the entrance regulation device 101A is permitted to pass (that is, when the value of the attribute information Pb is "0"), the group supervisory control device 104 determines the installation floor Fs (boarding floor) of the entrance regulation device 101A. and the destination floor Fd of the user permitted to pass through the entrance regulation device 101A are assigned as one hall call to any one car 100 (see steps S402 to S404 in FIG. 7). At this time, the allocation (call registration) of the hall call to the car 100 takes into account the upper limit value Rt of the occupancy rate set for each car 100, and assigns the allocated number of hall calls to each car 100. This is done so as not to exceed the upper limit number Nt (=passenger capacity number Ns×passenger rate upper limit value Rt). Here, the maximum number of passengers may be used as the boarding capacity Ns, or the maximum number of passengers with a margin (for example, 80% of the maximum number of passengers) may be used. .

In this embodiment, the group supervisory control device 104 updates the upper limit value Rt of the occupancy rate according to the number of users in the building Nc (number of people entering Na-number of people leaving Nb) (see FIG. 6). Therefore, in order to calculate the number of users Nc in the building, the group supervisory control device 104 uses attribute information Pb with a value of “0” (entrance device) to The number of users permitted to pass (that is, the number of intruders Na) is counted, and the attribute information Pb with a value of "1" (exit device) is used to control the passage of the exit regulation device 101B. count the number of users allowed to enter (ie, the number of exiters Nb).

Therefore, in step S103, when the value of the attribute information Pb acquired in step S101 is "0" (apparatus for entrance), the security server 102 counts the number of intruders Na as information necessary for elevator control. (at least attribute information Pb) and information (at least the installation floor Fs (boarding floor) of the entrance regulation device 101A and the destination floor Fd of the user) necessary for allocating hall calls (at least the installation floor Fs (boarding floor) of the entrance regulation device 101A and the destination floor Fd of the user) to the group supervisory control device 104 Send to On the other hand, when the value of the attribute information Pb acquired in step S101 is "1" (device for exit), the security server 102 regards the information necessary for elevator control as the information necessary for counting the number of people leaving Nb. Information (at least attribute information Pb) is transmitted to the group supervisory control device 104 .

More specifically, the security server 102 further has correspondence management data D2 in addition to the device management data D1 described above. FIG. 4B is a conceptual diagram showing an example of correspondence management data D2. In the correspondence management data D2, each identification information Pi of the recording medium Q is associated with the destination floor Fd initially set as the exit floor of the user identified by the identification information Pi. In the correspondence management data D2, in order to prevent leakage of the identification information Pi, for each identification information Pi of the recording medium Q, management information Pj (for example, attached to the IC card) corresponding to the identification information Pi on a one-to-one basis. (similar to a serial number) are associated.

Then, when the value of the attribute information Pb acquired in step S101 is "0" (apparatus for entrance), the security server 102 refers to the correspondence management data D2 to identify the successful authentication in step S102. The management information Pj and the destination floor Fd associated with the information Pi are acquired, and the device management data D1 is referred to, and the control device 101 associated with the device information Pd used for specifying the regulation device 101 in step S101 is obtained. Acquire the installation floor Fs. After that, the security server 102 transmits these pieces of information to the group supervisory control device 104 together with the device address Pa and the attribute information Pb (=“0”) acquired in step S101 (see FIG. 1).

On the other hand, when the value of the attribute information Pb acquired in step S101 is "1" (device for exit), the security server 102 transfers the attribute information Pb (="1") acquired in step S101 to the group management Send to control device 104 . At this time, the security server 102 may transmit the management information Pj, the device address Pa, etc. to the group supervisory control device 104 together with the attribute information Pb.

At least part of the data in the device management data D1 and correspondence management data D2 described above may be managed by the group management control device 104 instead of the security server 102 . In this case, instead of the security server 102, the group supervisory control device 104 acquires at least part of the information necessary for call registration from data managed by itself.

In the security management process (FIG. 3), if the security server 102 fails to authenticate the identification information Pi in step S102, the security server 102 confirms that the regulated device 101 identified by the device address Pa acquired in step S101 By controlling the operation, the gate is closed, thereby regulating (specifically, prohibiting) the passage of the user through the regulating device 101 (step S104B).

Such security management processing is executed by a processing unit configured within the security server 102 . As an example, this processing unit is configured with software by causing a processing device (such as a CPU) provided in the security server 102 to execute a program. The program may be stored in a portable storage device (for example, flash memory) in a readable state, or may be stored in another server in a downloadable manner, and the downloaded program may be stored in the security server 102. may be stored in a storage unit (not shown). As another example, the processing units described above may be implemented in hardware by building circuitry within the security server 102 .

<Elevator controller>
Elevator controllers 103 are provided one by one for each car 100 and control the operation of the corresponding car 100 . The elevator controller 103 is centrally managed and controlled by the group supervisory controller 104 .

<Group supervisory control device>
Each time the group supervisory control device 104 receives information necessary for elevator control from the security server 102, based on the attribute information Pb included in the information, the group supervisory control device 104 acquires the number of users Nc in the building. process, see FIG. 5), and updates the upper limit value Rt of the occupancy rate set for the car 100 according to the acquired number of users Nc (update process, see FIG. 6). Further, when the value of the attribute information Pb is "0" (entrance device), the group supervisory control device 104 performs the call registration processing (Fig. 7) is executed. An outline of these processes will be described below. Details thereof will be described later.

In the acquisition process (see FIG. 5), the group supervisory control device 104 counts the number of people Na when the value of the received attribute information Pb is "0" (entrance device). By subtracting the number of people leaving Nb from the number of people entering the building Na, the number of users Nc (=Na-Nb) in the building is calculated. Further, when the value of the received attribute information Pb is "1" (device for exit), the group supervisory control device 104 counts the number of exiting persons Nb, By subtracting from the number of people Na, the number of users in the building Nc (=Na-Nb) is calculated. In this manner, the group supervisory control device 104 obtains the number of users Nc in the building.

In the updating process (see FIG. 6), the group supervisory control device 104 updates the upper limit value Rt of the occupancy rate set for each car 100 according to the acquired number of users Nc in the building.

In the call registration process (see FIG. 7), the group supervisory control device 104 registers the platform call of the user permitted to pass through the entrance regulation device 101A (installation floor Fs (boarding floor) of the entrance regulation device 101A and the destination of the user). Fd) is assigned to any one car 100 (see steps S402 to S404 in FIG. 7). At this time, the group supervisory control device 104 considers the upper limit value Rt of the occupancy rate set for each car 100 (upper limit value Rt of the occupancy rate after update processing), Allocates to any one car 100 so that the allocated number does not exceed the allocated upper limit number Nt (=passenger capacity Ns×occupancy upper limit value Rt).

Further, when the car 100 is assigned a hall call, the group supervisory control device 104 controls the car 100 to reduce congestion based on the upper limit value Rt of the occupancy rate set for the car 100. The user who called the platform is notified whether the train is operating in a congestion alleviation mode that emphasizes transportation efficiency or in a transportation-oriented mode that emphasizes transportation efficiency (see steps S405 to S407 in FIG. 7). ).

In this embodiment, acquisition processing, update processing, and call registration are respectively executed by an acquisition processing unit 104A, an update processing unit 104B, and a call registration processing unit 104C configured in the group supervisory control device 104 (see FIG. 1). reference). As an example, these processing units are configured with software by causing a processing device (such as a CPU) included in the group supervisory control device 104 to execute a program. The program may be stored in a portable storage device (for example, flash memory) in a readable state, or may be stored in another server in a downloadable manner, and the downloaded program may be used for group management control. It may be stored in a storage unit (not shown) of device 104 . As another example, the processing units described above may be configured in hardware by constructing circuits within the group supervisory control device 104 .

Details of the acquisition process, the update process, and the call registration process executed by the group supervisory control device 104 will be described below.

[2] Control Processing Executed by Group Supervisory Control Device [2-1] Acquisition Processing FIG. Acquisition processing includes information necessary for elevator control (management information Pj, destination floor Fd, installation floor Fs, device address Pa, and information including attribute information Pb=“0”, or information including attribute information Pb=“1”). is received from the security server 102 by the group supervisory control device 104 .

When the acquisition process is started, the group supervisory control device 104 uses the information received from the security server 102 (hereinafter referred to as It is determined whether the value of the attribute information Pb included in the received information Pr) is "0" (apparatus for entrance) or "1" (apparatus for exit) (step S201). ).

Then, when the group supervisory control device 104 determines that it is "0" (entrance device) in step S201, it counts the number of intruders Na, thereby adding one to the intruder number Na. Add (step S202A). On the other hand, when the group supervisory control device 104 determines in step S201 that the number is "1" (exit device), it counts the number of exiting persons Nb, thereby increasing the number of exiting persons Nb by one. Add (step S202B).

After executing step S202A or S202B, the group supervisory control device 104 calculates the number of users in the building Nc (=Na-Nb) by subtracting the number of people leaving Nb from the number of people entering Na (step S203). In this manner, the group supervisory control device 104 obtains the number of users Nc in the building. After completing the acquisition process, the group supervisory control device 104 starts the next update process.

[2-2] Update Processing FIG. 6 is a flow chart showing update processing executed by the group supervisory control device 104 . When the update process is started, the group supervisory control device 104 substitutes the initial value r0 for the variable R (step S301). Here, the variable R is a variable for determining an update candidate value for the upper limit value Rt of the occupancy rate. Also, its initial value r0 is set to zero (0%) as an example. Note that the initial value r0 may be set to a value (for example, 0.1 (10%)) that can alleviate congestion in the car 100 .

Next, the group supervisory control device 104 uses the transport capacity Wq of the entire elevator with respect to the number of users Nc so that the transport capacity Wq becomes the required transport capacity Wqn of the target elevator. (update candidate value) is determined (steps S302 to S304).

Here, the transport capacity Wq used in this embodiment is the ratio of the number of people Nq transported per unit time that can be transported by all the cars 100 of the elevator to the number of users Nc in the building. The transportation capacity Wq is determined by the number of laps Ir for one car 100 per predetermined time (usually, the predetermined time is five minutes), the number of passengers per car 100 Ns, and the total number of cars Ng. is calculated by the following formula (1).

<<Formula (1)>>
Wq=Nq/Nc=(Ir*Ns*R*Ng)/Nc.

Specifically, the group supervisory control device 104 first calculates the transportation capacity Wq of the entire elevator by substituting the value of the variable R at that time into the equation (1) (step S302). After that, the group supervisory control device 104 determines whether or not the transport capacity Wq calculated in step S302 is equal to or greater than a predetermined value Wq0 (step S303). Here, the predetermined value Wq0 is set to be the lower limit value of the transport capacity Wqn required for the target elevator. As an example, such a lower limit value makes it possible to operate an elevator without making users wait for a long time at the platform, and is usually 0.12 (12%) or more depending on the use of the building. It is set to 0.20 (20%).

When the group supervisory control device 104 determines in step S303 that "the value of the transport capacity Wq is not equal to or greater than the predetermined value Wq0 (No)", the transport capacity Wq at that time is used to exhibit the necessary transport capacity Wqn. You can decide that you can't. In this case, the group supervisory control device 104 can determine in step S303 that "the value of the transport capacity Wq is equal to or greater than the predetermined value Wq0 (Yes)" in order to derive the value of the variable R that can exhibit the required transport capacity Wqn. The value of the variable R is increased until Specifically, the group supervisory control device 104 adds a predetermined amount of change Δr to the value of the variable R at that time as a new value of the variable R (step S304). The process from step S302 is executed again. Then, the group supervisory control device 104 repeats the series of processes from step S304 until it can be determined in step S303 that "the value of the transportation capacity Wq is equal to or greater than the predetermined value Wq0 (Yes)".

If the group supervisory control device 104 determines in step S303 that "the value of the transport capacity Wq is equal to or greater than the predetermined value Wq0 (Yes)", it determines the required transport capacity with the transport capacity Wq at that time. It can be determined that Wqn can be exhibited. In this case, the group supervisory control device 104 uses the value of the variable R at that time to update the upper limit value Rt of the occupancy rate set for each car 100 (step S305). That is, in this embodiment, the group supervisory control device 104 uniformly updates the upper limit value Rt of the occupancy rate using the same value of the variable R in all the cars 100 provided in the building.

According to such update processing, it is possible to update the upper limit value Rt of the occupancy rate set for each car 100 so that the required transport capacity Wqn can be exhibited in the target elevator.

[2-3] Call Registration Processing FIG. 7 is a flow chart showing call registration processing executed by the group supervisory control device 104 . In the call registration process, information necessary for elevator control (management information Pj, destination floor Fd, installation floor Fs, device address Pa, and information including attribute information Pb=“0” or attribute information Pb=“1 ) is received from the security server 102 by the group supervisory control device 104 .

When the call registration process is started, the group supervisory control device 104 determines whether or not the information (receiving information Pr) includes information necessary for hall call allocation (call registration). It is determined whether the value of the attribute information Pb included in the received information Pr is "0" (apparatus for entrance) or "1" (apparatus for exit) (step S401).

Then, when the group supervisory control device 104 determines in step S401 that the value is "1" (exit device), the received information Pr is the information necessary for allocating hall calls (call registration). , the call registration process is terminated without executing a series of processes (processes after step S402) relating to hall call allocation (call registration).

On the other hand, when the group supervisory control device 104 determines in step S401 that the value is "0" (entrance device), the received information Pr is information necessary for hall call allocation (call registration). is included, a series of processes (processes after step S402) relating to hall call allocation (call registration) are executed. Specifically, it is as follows.

The group supervisory control device 104 extracts cars 100 that can be assigned hall calls (step S402). Specifically, the group supervisory control device 104 determines that the number of hall calls that have already been allocated to the car 100 has reached the allocation upper limit number Nt (=passenger capacity Ns x passenger capacity upper limit value Rt). Extract what is not.

After executing step S402 (after extracting the car 100 that can be the allocation target), the group supervisory control device 104 determines whether or not the car 100 that can be the allocation target has been extracted. It is determined whether or not the value of the extraction number Nd of the car 100 is 1 or more (step S403).

Then, when the group supervisory control device 104 determines that "one or more (Yes)" is determined in step S403, it can determine that the car 100 that can be the allocation target has been extracted. An optimum car 100 is selected from the cars 100 thus obtained, and a hall call is assigned to the selected car 100 (step S404).

On the other hand, when the group supervisory control device 104 determines "not equal to or greater than 1 (No)" in step S403, it can determine from that determination that the car 100 that can be the allocation target could not be extracted. cannot perform hall call allocation. In this case, even if the car 100 that can be the allocation target cannot be extracted at that time, as time elapses, the upper limit value Rt of the occupancy rate is updated and becomes larger, and the operation of the elevator progresses. A car 100 that can be extracted as an allocation target appears due to an event such as resetting the allocation of another user.

A case in which the car 100 to be allocated cannot be extracted is mainly when the upper limit value Rt of the occupancy rate is small and the transportation capacity of the elevator itself is relatively low. It is conceivable that the transportation capacity of the elevator itself is becoming insufficient due to the increase in traffic. In the present embodiment, even in such a case, as the number of users Nc in the building increases, the upper limit value Rt of the occupancy rate is updated and becomes larger, so cars 100 that can be extracted as allocation targets tend to appear.

Therefore, the group supervisory control device 104 repeats the processing from step S402 until it can be determined that "the number is 1 or more (Yes)" in step S403.

According to such processing, the allocation (call registration) of the hall call to the car 100 is performed by considering the upper limit value Rt of the occupancy rate set for each car 100. allocation upper limit number Nt (=passenger capacity number Ns×occupancy rate upper limit value Rt).

After allocating the hall call to the car 100 in step S404, the group supervisory control device 104 determines whether the car 100 is in a congestion alleviation mode based on the upper limit value Rt of the occupancy rate set for the car 100. The user who called the boarding hall is notified whether the train is operated in a congestion alleviating mode emphasizing the traffic or in a transportation emphasizing mode emphasizing the efficiency of transportation.

Specifically, the group supervisory control device 104 determines whether the transport mode Pm of the car 100 is the congestion alleviating mode or the transport-focused mode. It is determined whether or not the value Rt is equal to or less than the mode determination threshold value r1 (step S405). As an example, the mode determination threshold value r1 is an upper limit value that can alleviate congestion in the car 100, and is set to 0.2 (20%), for example.

Then, when the group supervisory control device 104 determines in step S405 that "it is equal to or less than the threshold value r1 for mode determination (Yes)", it determines that the transport mode Pm of the car 100 is set to the "congestion alleviation mode". (step S406A). On the other hand, when the group supervisory control device 104 determines in step S405 that "it is not equal to or less than the threshold value r1 for mode determination (No)", the transport mode Pm of the car 100 is changed to the "transport-focused mode". Determine (step S406B).

After that, the group supervisory control device 104 sets the information (car information Pg) identifying the assigned car 100 and the transportation mode Pm of the car 100 to the regulation specified by the device address Pa in the received information Pr. It is displayed on the display device 2 of the device 101 (step S407). FIGS. 8A and 8B are conceptual diagrams illustrating screens displayed on the display device 2 of the entrance regulation device 101A according to the transportation mode Pm. These figures show the case where user management information Pj and destination floor Fd are displayed in addition to car information Pg and transportation mode Pm.

As a result, the user checks the information displayed on the display device 2 when passing through the entrance regulation device 101A, thereby recognizing the car 100 in which he or she should ride and what kind of car 100 is. It is possible to recognize whether the vehicle is operated in the transportation mode Pm. Information such as the car information Pg and the transport mode Pm is not limited to being displayed on the display device 2, and may be notified to the user by other means such as voice output from a speaker.

According to the control process of the present embodiment, the number of passengers in the building is set so that the upper limit value Rt of the boarding rate set for each car 100 becomes smaller when the number of passengers Nc is small. It is updated according to Nc. Therefore, when the number of users Nc is small, the congestion in the car 100 is reliably alleviated by reducing the upper limit value Rt of the occupancy rate. Further, in this embodiment, the upper limit value Rt of the occupancy rate is updated so that the required transportation capacity Wqn can be exhibited in the target elevator. Therefore, according to the control process of the present embodiment, it is possible to alleviate congestion in the car 100 while exhibiting the required transportation capacity Wqn in the elevator.

Furthermore, according to the control process of the present embodiment, the upper limit value Rt of the occupancy rate set for each car 100 increases when the number of users Nc in the building increases. It is updated according to the number of persons Nc. Therefore, when the number of users Nc increases, the upper limit value Rt of the occupancy rate increases, thereby improving the transport capacity of the elevator itself (increasing the number of people that can be transported in one transport). As a result, it becomes possible to transport many users efficiently.

[3] Modification [3-1] First Modification In the update process described above, the group supervisory control device 104, instead of uniformly updating the upper limit Rt of the occupancy rate in all the cars 100, In at least part of the car 100, the upper limit value Rt of the occupancy rate may be updated according to the number of users Nc in the building.

As an example, the group supervisory control device 104, in any one car 100 among the cars 100 provided in the elevator, sets the upper limit value Rt of the riding ratio set for the car 100 to the number of users in the building. Nc, and when the upper limit value Rt of the occupancy rate reaches a predetermined value r2, the upper limit value Rt of the occupancy rate of another car 100 set for the car 100 is updated. can be updated according to the number of users Nc in the building. The group supervisory control device 104 can update the upper limit value Rt of the passenger occupancy rate in this manner by changing the car 100 to be updated every time the upper limit value Rt of the passenger occupancy rate reaches a predetermined value r2. can. This example will be specifically described below.

<Update process>
FIG. 9 is a flowchart showing an example of update processing executed in the first modified example. When the update process is started, the group supervisory control device 104 substitutes the initial value r0 for each variable R(x) (x is an integer satisfying 1≤x≤Ne; Ne is the total number of cars 100). (step S311). Here, the cars 100 are numbered from 1st to Neth to identify them, and the variable R(x) is the upper limit value Rt ( x) is a variable for determining the update candidate value for x). Also, the initial value r0 is set to a value (for example, 0.1 (10%)) that can alleviate congestion in the car 100 . In step S311, 1 is substituted for the variable n as its initial value. Here, the variable n is a variable for specifying the number of the car 100 to be judged in step S314A, which will be described later.

Next, the group supervisory control device 104 uses the transport capacity Wq of the entire elevator with respect to the number of users Nc to adjust the variable R(x ) (update candidate value) is determined (steps S312 to S314).

Here, the transport capacity Wq used in this modification is obtained by using the transport capacity Wr(x) of each car 100, and the transport capacity Wr(x) of each of the first car 100 to the Ne-th car 100. x) (total transport capacity Wr(x)). The transport capacity Wr(x) is the ratio of the number of people Nr(x) transported per unit time that can be transported by the x-th car 100 to the number of users Nc in the building. Then, this transport capacity Wr(x) is determined by the number of laps Ir(x) of the x-th car 100 per predetermined time (usually, the predetermined time=5 minutes) and the number of passengers of the x-th car 100. It is calculated by the following formula (2) using the number Ns(x).

<<Formula (2)>>
Wr(x)=Nr(x)/Nc=(Ir(x)*Ns(x)*R(x))/Nc.

Specifically, the group supervisory control device 104 first substitutes the value of the variable R(x) at that time into the equation (2) to obtain the transport capacity Wr(x) of each car 100, and calculates the transport capacity Wr(x). By calculating the sum of Wr(x), the transportation capacity Wq of the entire elevator is calculated (step S312). After that, the group supervisory control device 104 determines whether or not the transport capacity Wq calculated in step S312 is equal to or greater than a predetermined value Wq0 (step S313). Here, the predetermined value Wq0 is set to be the lower limit value of the transport capacity Wqn required for the target elevator. As an example, such a lower limit value makes it possible to operate an elevator without making users wait for a long time at the platform, and is usually 0.12 (12%) or more depending on the use of the building. It is set to 0.20 (20%).

If the group supervisory control device 104 determines in step S313 that "the value of the transport capacity Wq is not equal to or greater than the predetermined value Wq0 (No)", the transport capacity Wq at that time will exhibit the required transport capacity Wqn. You can decide that you can't. In this case, the group supervisory control device 104 determines in step S313 that "the value of the transport capacity Wq is equal to or greater than the predetermined value Wq0 (Yes)" in order to derive the value of the variable R(x) that can exhibit the required transport capacity Wqn. The value of the variable R(x) is increased in order from the first car 100 until it can be determined. Specifically, it is as follows.

If the group supervisory control device 104 determines in step S313 that "the value of the transport capacity Wq is not equal to or greater than the predetermined value Wq0 (No)", it determines whether the value of the variable R(n) is smaller than the predetermined value r2. (step S314A). Here, the predetermined value r2 is set to a value (for example, 0.8 (80%)) that allows the car 100 itself to exhibit a high transportation capacity.

Then, when the group supervisory control device 104 determines in step S314A that the value is smaller than the predetermined value r2 (Yes), the variable R(n) for the n-th car 100 is determined based on that determination. has not yet reached the predetermined value r2, and it can be determined that there is room for increasing the value of the variable R(n). In this case, group supervisory control device 104 adds a predetermined amount of change Δr to the value of variable R(n) as a new value of variable R(n) (step S314B), and uses the new value. , the process from step S312 is executed again.

On the other hand, when the group supervisory control device 104 determines in step S314A that "the value is not smaller than the predetermined value r2 (No)", the variable R(n) for the n-th car 100 is changed to It can be determined that the variable R(n) has already reached the predetermined value r2 and there is no room to increase the value of the variable R(n). In this case, the group supervisory control device 104 converts the value of the variable n by 1 into a new value of the variable n (step S314C), and uses the new value to execute the process of step S314A again. Then, the group supervisory control device 104 repeatedly executes a series of processes from step S314C until it can be determined that "the value is smaller than the predetermined value r2 (Yes)" in step S314A. That is, the group supervisory control device 104 sequentially increases the value of the variable n until it finds a variable R(n) that has room for increasing the value.

According to such processing, the processing for increasing the variable R(n) (step S314B) starts from the first (n=1) car 100, and each time the variable R(n) reaches the predetermined value r2, Then, the target car 100 is replaced with the one with the next number, and it is carried out sequentially.

Then, when the group supervisory control device 104 determines in step S313 that "the value of the transport capacity Wq is equal to or greater than the predetermined value Wq0 (Yes)," It can be determined that the transportation capacity Wqn can be exhibited. In this case, the group supervisory control device 104 uses the value of the variable R(x) at that time to update the upper limit value Rt(x) of the occupancy rate set for each car 100 (step S315).

Thus, in this modification, the group supervisory control device 104 does not uniformly update the upper limit value Rt(x) of the occupancy rate, but rather The upper limit value Rt(x) of the occupancy rate is updated only for at least some of the cars 100 corresponding to the number of passengers Nc.

According to such update processing, even if the number of users Nc in the building increases, the required transportation capacity Wqn can be exhibited in the target elevator, and the car 100 with reduced congestion can be left as much as possible. be possible.

<Call registration process>
According to the updating process of this modified example, the car 100 is operated in the congestion alleviating mode with the upper limit value Rt(x) of the occupancy rate set to a value equal to or less than the mode determination threshold value r1. The upper limit value Rt(x) of is set to a value larger than the mode determination threshold value r1, and the train is operated in the transport-focused mode. Therefore, in this modification, the group supervisory control device 104 executes call registration processing as follows. In the following, points different from the call registration process described in the embodiment will be specifically described with reference to FIG.

In step S402 (a step of extracting cars 100 that can be assigned), the group supervisory control device 104 selects a hall call that has already been assigned among the cars 100 (first to Ne-th cars 100). Those whose allocation number does not reach the allocation upper limit number Nt(x) (=passenger capacity Ns(x)×occupancy rate upper limit value Rt(x)) are extracted. Then, in step S404 (the step of assigning hall calls), the group supervisory control device 104 selects the optimum car 100 (x=xc) from the cars 100 extracted in step S402, and calls the car 100. assign.

After allocating the hall call to the car 100 (x=xc) in step S404, the group supervisory control device 104 determines the corresponding The user who called the boarding area is notified of whether the car 100 is operated in a congestion alleviation mode emphasizing congestion alleviation or in a transportation emphasizing mode emphasizing transportation efficiency. .

Specifically, the group supervisory control device 104 determines whether the transport mode Pm(xc) of the car 100 (x=xc) is the congestion alleviating mode or the transport-focused mode. It is determined whether or not the set upper limit value Rt(xc) of the occupancy rate is equal to or less than the mode determination threshold value r1 (step S405). As an example, the mode determination threshold value r1 is an upper limit value that can alleviate congestion in the car 100, and is set to 0.2 (20%), for example.

Then, when the group supervisory control device 104 determines in step S405 that "it is equal to or less than the threshold value r1 for mode determination (Yes)", based on that determination, the transport mode Pm ( xc) is determined to be the "congestion alleviation mode" (step S406A). On the other hand, when the group supervisory control device 104 determines in step S405 that "it is not equal to or less than the threshold value r1 for mode determination (No)", the transport mode Pm(xc) of the car 100 (x=xc) is determined based on the determination. ) is determined to be the “transport-focused mode” (step S406B).

According to such call registration processing, even when the car 100 operated in the congestion alleviation mode and the car 100 operated in the transport-oriented mode coexist, the car 100 (x= xc) transport mode Pm(xc) is determined based on the upper limit value Rt(xc) of the occupancy rate set for the car 100 and notified to the user. Therefore, it is possible to accurately inform the user of the transportation mode Pm(x) in which the car 100 in which the user should ride is operated.

<Other examples>
In the updating process of this modified example, the group supervisory control device 104 is limited to the case where the number of cars 100 to be updated for the upper limit value Rt of the riding ratio is increased one by one according to the number of users Nc in the building. First, the cars 100 are grouped into several groups, and for each group, the upper limit value Rt of the boarding rate is uniformly updated until it reaches a predetermined value r2. You may increase one by one according to.

That is, the group supervisory control device 104 sets the upper limit value Rt of the occupancy rate set for some cars 100 (groups) out of the cars 100 provided in the elevator to the number of passengers in the building. update in accordance with the number Nc, and when the upper limit value Rt of the occupancy rate reaches a predetermined value r2, in some other car 100 (another group), It is possible to update the upper limit value Rt of the occupancy rate in accordance with the number of users Nc in the building. Then, the group supervisory control device 104 sequentially updates the upper limit value Rt of the occupancy rate in this manner by changing the car 100 (group) to be updated each time the upper limit value Rt of the occupancy rate reaches a predetermined value r2. It can be carried out.

[3-2] Second Modified Example In the update process described above, for any one or some of the cars 100, the upper limit value Rt of the occupancy rate is set to the initial value r0 without being updated. may be kept as is. According to such update processing, even when the number of users Nc in the building increases, it is possible to always leave the car 100 in which the congestion is alleviated.

[3-3] Third Modification The update process described above is not limited to being executed each time the number of users Nc in the building changes (that is, each time the acquisition process (see FIG. 5) is executed), It may be executed only when there is a predetermined number of changes in the number of users Nc in the building.

[3-4] Fourth Modification In the update process described above, the update candidate value for the upper limit value Rt of the occupancy rate is determined by changing the value of the variable R and searching for a value that satisfies Wq≧Wq0 (Fig. 6, steps S302 to S304), the following other methods may be used as appropriate.

As an example, a method of directly deriving the update candidate value by solving the equation Wq=Wq0 (see formula (1) for the formula expressing Wq) for the variable R may be used.

As another example, updating is performed by associating a value (update candidate value) that can exhibit the required transport capacity Wqn as the upper limit value Rt of the occupancy rate with each of several values that can be obtained as the number of users Nc in the building. A method is used in which management data (table) is prepared in advance, and when the number of users Nc in the building is obtained, a value (update candidate value) corresponding to the number of users Nc is obtained from the update management data. may

[3-5] Fifth Modification In the acquisition process described above, information (attribute information Pb) sent from the security server 102 each time authentication is successful is used to count the number of people entering Na and the number of people leaving Nb. It is not limited to the counting method (steps S201 to S202B in FIG. 5), and another method such as a method of counting based on an image of a surveillance camera may be used as appropriate.

[3-6] Sixth Modification In the control process described above, Nt=Ns×Rt ( Alternatively, considering that there is a relationship of Nt(x)=Ns(x)×Rt(x)), instead of updating the upper limit value Rt of the occupancy rate, the group supervisory control device 104 changes the allocation upper limit number Nt (or Nt(x)) may be updated according to the number of users Nc in the building. That is, the group supervisory control device 104 may directly update the upper limit allocation number Nt instead of indirectly updating the upper limit allocation number Nt by updating the upper limit value Rt of the occupancy rate.

[3-7] Other Modifications The above-described elevator control processing (acquisition processing, update processing, and call registration processing) is not limited to elevators having a plurality of cars 100, It can also be applied to elevators. In this case, the elevator control device 103 executes the above-described elevator control processing (acquisition processing, update processing, and call registration processing) as an embodiment of the control device according to the present invention.

The entire elevator configuration described above may be modified so that the regulation device 101 authenticates the identification information Pi, or the group supervisory control device 104 authenticates the identification information Pi, without providing the security server 102. . In this case, the elevator control process may be performed using only the identification information Pi without using the management information Pj.
