Description

The present invention relates to an elevator control technique in which a regulatory device such as a security gate is installed.

For example, in Patent Document 1, a regulatory device such as a security gate is installed on a specific floor (lobby floor, etc.) of an elevator, and the regulatory device is based on identification information (unique ID, etc.) read from an IC card possessed by the user. A technique for determining whether or not to allow passage has been proposed. Further, in Patent Document 1, a user who has been determined to permit the passage of the regulatory device is assigned to the optimum car in consideration of the destination floor associated with the identification information of the user. Technology has been proposed.

Japanese Unexamined Patent Publication No. 2013-67489

In the elevator control technology described above, when a user whose permission has been determined is assigned to the car (call registration), various decisions (allocation determination) are made to allocate the user to the optimum car. ) Is done. Further, for such a judgment, it is conceivable to use, for example, the average time required for one user to pass through the regulatory device as a judgment criterion.

As an example, in an elevator in which a regulatory device is installed, in order to improve the operation efficiency of the elevator, the present inventors view the car from the specific floor while the vehicle is stopped or just before arrival. By having a series of users (users who can board without interruption) with the same destination direction at the time, it is possible to start the car with the shortest possible stop time while increasing the number of passengers. I think it is preferable.

Therefore, the present inventors, when allocating (call registration) to a car for a user who has been determined to permit the passage of the regulated device, the target user who is the target of the call registration. In the above, it is determined whether or not both of the following conditions (1) and (2) are satisfied, and if it is determined that all of the conditions are satisfied, the vehicle is stopped at a specific floor or just before arrival. We are proposing technologies such as assigning target users to the car.

conditions:
(1) During the predetermined period until the permission decision is made for the target user, the permission decision is made for another user whose destination direction is the same as that of the target user when viewed from a specific floor. (2) The car assigned to the other user above is stopped on a specific floor or just before arrival.

In the above condition (1), the predetermined period is used as a judgment standard for judging whether or not the target user is a series of users in relation to another user for whom the permission judgment has been made. Then, in this predetermined period, for example, the average time required for one user to pass through the regulation device is used.

In recent years, various security gates having different structures (types) and operation settings have been developed as regulatory devices according to convenience and safety. For this reason, the average time required for one user to pass through the regulatory device often differs depending on the structure (type) and operation setting of the regulatory device installed in the elevator. For this reason, it has become necessary to review the criteria for determining whether or not the above condition (1) is satisfied, such as the predetermined period, according to the structure (type) and operation settings of the regulatory device. There is. However, if such a review is performed manually, the operator will be forced to perform complicated setting work.

Therefore, an object of the present invention is to control an elevator in which a regulatory device is installed so that control according to the structure (type) and operation setting of the regulatory device can be performed without forcing an operator to perform complicated setting work. It is to provide the device.

The control device according to the present invention is applicable to an elevator in which a regulation device for restricting entry to a landing is installed, and includes a call registration processing unit, an acquisition processing unit, and an update processing unit. In the elevator, it is determined whether or not to allow the user to pass through the regulated device, and the call registration processing unit performs call registration for each user who has been determined to permit the passage of the regulated device. When performing the call registration, an allocation decision is made to allocate the user to the car. Then, every time a permission decision is made, the acquisition processing unit acquires the time interval from the previous permission decision to the current permission decision if another permission decision is made before the permission decision. The update processing unit updates the determination criteria used for the allocation determination by using at least a part of the time interval acquired by the acquisition processing unit.

According to the control device, the determination standard is automatically updated based on the time interval acquired by the acquisition processing unit. Here, the time interval acquired by the acquisition processing unit is an actually measured value of the time interval from the previous permission decision made in the regulatory device to the current permission decision, and is the actual value required for passing through the regulatory device. It reflects the time of. The structure (type) and operation settings of the regulatory device are likely to be reflected in the actual time required for passing the regulatory device. Therefore, by updating the judgment criteria based on the time interval (actual measurement value) acquired by the acquisition processing unit, the judgment criteria are set to the optimum values according to the structure (type) and operation settings of the regulatory device. It becomes easy to be done.

The elevator may have a regulatory device installed on a specific floor, and the control device may be applied to such an elevator. In that case, the call registration processing unit, as an allocation decision, in the target user who is the target of the call registration, (1) during the predetermined period until the permission decision is made for the target user, the specific floor. The condition that the permission decision is made for another user whose destination direction is the same as the target user when viewed from the above, and (2) the car assigned to the other user is on a specific floor. It is determined whether or not both the conditions of being stopped or just before arrival are satisfied, and if it is determined that both conditions are satisfied, the above-mentioned assigned vehicle and the same vehicle will be used as the target. May be assigned. Further, the renewal processing unit may renew the predetermined period as a judgment standard used for the allocation judgment. According to this configuration, the predetermined period is updated based on the time interval (actual measurement value) acquired by the acquisition processing unit, so that the predetermined period is optimal according to the structure (type) and operation setting of the regulatory device. It becomes easy to set a value (length).

In the control device, the acquisition processing unit may acquire the time interval for each time frame of a predetermined length, and may further acquire the number of users for whom permission is determined within the time frame. Then, even if the update processing unit updates the above-mentioned determination criteria (including the above-mentioned predetermined period) by using the time interval acquired in the time frame in which the value of the number of users in the above-mentioned time frame satisfies the predetermined condition. good.

More specifically, the elevator may be equipped with a plurality of regulatory devices, and the control device may be applied to such an elevator. In that case, the acquisition processing unit may acquire both the time interval and the number of users for each regulatory device and each time frame. Then, the update processing unit uses the time interval acquired in the combination in which the value of the number of users in the combination of the regulation device and the time frame satisfies the above-mentioned predetermined condition, and uses the above-mentioned determination criteria (including the above-mentioned predetermined period). May be updated.

In these configurations, when the value of the number of users is large, it is assumed that the users have passed through the regulation device without interruption as the passage status of the users in the regulation device. Therefore, by setting the above-mentioned predetermined conditions so that the time frame or combination that can assume the passing situation of such a user is extracted, the time interval (actual measurement value) acquired in the time frame or combination that satisfies the predetermined condition is obtained. ) Makes it easier for the user to approach the optimal time required to pass the regulatory device in an uninterrupted situation. Therefore, the above-mentioned judgment criteria (including the above-mentioned predetermined period) can be easily updated to the optimum value.

When the elevator is equipped with a plurality of regulation devices and the control device is applied to such an elevator, the acquisition processing unit acquires a time interval for each regulation device and regulates the elevator. The number of users who have been determined to allow the passage of the device may be further acquired. Then, the update processing unit may update the above-mentioned determination criteria (including the above-mentioned predetermined period) by using the time interval acquired in the regulation device in which the value of the number of users among the regulated devices satisfies the predetermined condition. .. Here, as in the above case, when the value of the number of users is large, it is assumed that the users have passed through the regulation device without interruption as the passage status of the users in the regulation device. Therefore, by setting the above-mentioned predetermined conditions so that the regulation device that can assume the passing situation of such a user is extracted, the time interval (actual measurement value) acquired by the regulation device that satisfies the predetermined conditions can be used. It facilitates access to the optimal time required for a person to pass through a regulatory device in an uninterrupted situation. Therefore, the above-mentioned judgment criteria (including the above-mentioned predetermined period) can be easily updated to the optimum value.

According to the present invention, in an elevator in which a regulating device is installed, it is possible to perform control according to the structure (type) and operation setting of the regulating device without forcing an operator to perform complicated setting work.

It is a conceptual diagram which showed an example of the data acquired by the execution of the acquisition process in a group management control device.

[1] Overall configuration of the elevator FIG. 1 is a conceptual diagram showing the overall configuration of the elevator. As shown in FIG. 1, the elevator includes a car 100, a regulation device 101, a security server 102, an elevator control device 103, and a group management control device 104. The group management control device 104 is an embodiment of the control device according to the present invention. Hereinafter, the configuration of each part will be specifically described. Although not particularly limited, FIG. 1 shows a configuration in which three car 100s and three regulation devices 101 are provided as an example of an elevator.

<Regulatory device>
The regulation device 101 is a device that regulates the entry of the elevator into the landing H on a specific floor (lobby floor, etc.) of the building, such as a security gate. Then, device information Pd for identifying them is set in the regulation device 101. Further, the regulation device 101 includes a reading device 1 that reads information from a recording medium Q (IC card, magnetic card, etc.) possessed by the user, and a display device that displays information on the car 100 that the user should board. 2 and are provided. Here, the recording medium Q records the identification information Pi (unique information for identifying the recording medium Q, such as a unique ID) of the user who possesses the recording medium Q, and the reading device 1 identifies the information from the recording medium Q. Read the information Pi. Further, on the display device 2, as information on the car 100, information for identifying the car 100 (number, symbol, etc., hereinafter, this information is referred to as "car car information Pg") and the like are displayed.

The reading method of the recording medium Q by the reading device 1 may be a contact type or a non-contact type that reads information by short-range communication such as NFC (Near Field Communication). , Not particularly limited. Further, the recording medium Q is not limited to a card-shaped one, but may be a stick-shaped one or a chip-shaped one. Further, a portable information terminal such as a smartphone capable of short-range communication (NFC or the like) with the reading device 1 may be used as the recording medium Q.

The identification information Pi read by the reading device 1 is used in the security server 102 for authentication for determining whether or not to allow the user to pass through the regulating device 101. 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 regulation device 101 transmits the device information Pd of the regulation device 101 to the security server 102 together with the identification information Pi in order to make the security server 102 recognize the position of the source of the identification information Pi. The regulatory device 101 may transmit the device information of the reading device 1 (that is, the reading device 1 that has read the identification information Pi) provided in itself as the device information Pd to the security server 102.

<Security server>
In order to maintain high security, the security server 102 authenticates the identification information Pi transmitted from the regulation device 101, and permits the user to pass through the regulation device 101 only when the authentication is successful. , Information associated with the identification information Pi that has been successfully authenticated (that is, information necessary for the call registration process described later) is transmitted to the group management control device 104 (authentication process). The details of the authentication process will be described below.

FIG. 2 is a flowchart showing an authentication process executed by the security server 102. The authentication process is started when the security server 102 receives information (identification information Pi and device information Pd) from the regulation device 101. When the authentication process is started, the security server 102 authenticates the received identification information Pi in order to determine whether or not to allow the user to pass through the regulation device 101 (step S101).

When the security server 102 succeeds in authenticating the identification information Pi in step S101, the security server 102 determines permission to allow the user to pass through the regulation device 101. In that case, the security server 102 identifies the regulatory device 101, which is the source of the identification information Pi that has been successfully authenticated, based on the received device information Pd. Then, the security server 102 controls the specified regulatory device 101 to open the gate, thereby permitting the user to pass through the regulatory device 101 (step S102A).

Specifically, the security server 102 has the device management data D1. FIG. 3A is a conceptual diagram showing an example of device management data D1. In the device management data D1, for each device information Pd, the device address Pa (IP address, etc.) used for transmitting information to the regulation device 101 identified by the device information Pd, and the installation floor Fs of the regulation device 101. , Are associated with each other. Then, the security server 102 reads the device address Pa corresponding to the received device information Pd from the device management data D1 and controls the regulation device 101 specified by the read device address Pa to open the gate, thereby restricting the regulation. Allow the user to pass through the device 101.

After step S102A, the security server 102 transmits the information associated with the identification information Pi that was successfully authenticated in step S101 (that is, the information required for the call registration process described later) to the group management control device 104. (Step S103).

Specifically, the security server 102 further has the correspondence management data D2 in addition to the device management data D1 described above. FIG. 3B is a conceptual diagram showing an example of correspondence management data D2. In the correspondence management data D2, the initial setting floor Fd initially set as the disembarkation floor of the user identified by the identification information Pi is associated with each identification information Pi of the recording medium Q. Further, in the correspondence management data D2, in order to prevent leakage of the identification information Pi, the management information Pj (for example, attached to the IC card) corresponding to the identification information Pi on a one-to-one basis for each identification information Pi of the recording medium Q is attached. (Something like a serial number) is associated.

Then, the security server 102 reads the management information Pj and the initial setting floor Fd associated with the identification information Pi that succeeded in authentication in step S101 from the corresponding management data D2. Further, the group management control device 104 reads the installation floor Fs associated with the device information Pd from the device management data D1 by using the device information Pd transmitted from the regulation device 101 together with the identification information Pi.

After that, the security server 102 transmits the read information (management information Pj, initial setting floor Fd, and installation floor Fs) to the group management control device 104 (see FIG. 1). At this time, the security server 102 also transmits the device address Pa read in step S102A to the group management control device 104. At least a part of the data in the device management data D1 and the 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, the group management control device 104 reads at least a part of the information necessary for the call registration process from the data managed by itself.

If the authentication of the identification information Pi fails in step S101, the security server 102 determines that the user is not allowed to pass through the regulation device 101. In that case, the security server 102 identifies the regulatory device 101, which is the source of the identification information Pi that failed in authentication, based on the received device information Pd. Then, the security server 102 controls (prohibits) the passage of the user in the regulation device 101 by controlling the specified regulation device 101 and closing the gate (step S102B).

Such an authentication process may be executed by a processing unit configured by hardware by constructing a circuit in the security server 102, or a processing device such as a CPU included in the security server 102 may execute a program. It may be executed by a processing unit configured by software. Further, the program may be stored in a portable storage device (for example, a flash memory or the like) in a readable state, or is stored in a downloadable state on another server or the like, and the downloaded one is the security server 102. It may be stored in a storage unit (not shown).

<Elevator control device>
The elevator control device 103 is provided so as to correspond to the car 100 one by one, and controls the operation of the car 100 corresponding to itself. The elevator control device 103 is centrally managed and controlled by the group management control device 104.

<Group management control device>
The group management control device 104 receives information (management information Pj, initial setting floor Fd, installation floor Fs, and device) from the security server 102 each time a permission determination is made to the user to allow the passage of the regulation device 101. (Including the address Pa) is received, and the call registration is performed using the received information (hereinafter referred to as "received information Pr") (call registration process, see FIG. 4). Specifically, it is as follows.

In the call registration process, the group management control device 104 uses the initial setting floor Fd and the installation floor Fs in the received information Pr as the destination floor Fc1 and the departure floor Fc2 of the user whose permission has been determined, and the destination floor Fc1 and the installation floor Fs. The departure floor Fc2 is assigned to any one car 100 as one landing call (see steps S203A and S203B in FIG. 4). After that, the group management control device 104 displays the information for identifying the assigned car 100 (car car information Pg) on the display device 2 of the regulation device 101 specified by the device address Pa in the received information Pr. As a result, the user can recognize the car 100 to be boarded by confirming the car information Pg displayed on the display device 2 when passing through the regulation device 101.

The group management control device 104 is used for various purposes for allocating the user to the optimum car 100 when the user whose permission is determined by the security server 102 is assigned to the car 100 (call registration). Make a proper judgment (allocation judgment).

As an example, in an elevator in which a regulatory device 101 is installed, in order to improve the operation efficiency of the elevator, the car 100, which is stopped at a specific floor or is about to arrive, is directed to the destination when viewed from the specific floor. It is preferable to have a series of users (users who can get on without interruption) having the same number of passengers on board, because it is possible to start the car 100 with the shortest possible stop time while increasing the number of passengers.

Therefore, in the present embodiment, the group management control device 104 is the target of the call registration when the user whose permission is determined by the security server 102 is assigned to the car 100 (call registration). It is determined whether or not the following conditions (1) and (2) are satisfied by the target user.

conditions:
(1) During the predetermined period Tc until the permission decision is made for the target user, the permission decision is made for another user whose destination direction is the same as that of the target user when viewed from a specific floor. What has been done (see step S201 in FIG. 4)
(2) The car 100 assigned to the other user is stopped at a specific floor or just before arrival (see step S202 in FIG. 4).

Here, the above condition (1) is a condition that the target user is a series of users in relation to another user (that is, the previous user) for whom the permission decision has been made. , The predetermined period Tc is used as a criterion for determining whether or not such a condition is satisfied (that is, a criterion for determining allocation). Further, a preset value (length) is used for the predetermined period Tc.

Then, when the group management control device 104 determines that both of the above conditions (1) and (2) are satisfied, the group management control device 104 allocates the target user to the same car 100 as the assigned car 100 (the target user). See step S203A in FIG. 4).

In such a call registration process, the optimum value (length) of the predetermined period Tc, which is a judgment standard, differs depending on the structure (type), operation setting, etc. of the regulating device 101, and therefore the structure (type) and operation. It is preferable to review it according to the settings and the like. However, if such a review is performed manually, the operator will be forced to perform complicated setting work.

Therefore, in the present embodiment, the group management control device 104 further performs the following processing so that the optimum value (length) of the predetermined period Tc, which is the determination standard, can be automatically updated. .. That is, each time the permission judgment is made, the group management control device 104 sets the time interval T from the previous permission judgment to the current permission judgment if another permission judgment is made before the permission judgment. Acquire (acquisition process). Further, the group management control device 104 updates the predetermined period Tc, which is a determination criterion, by using at least a part of the acquired time interval T (update process). This makes it possible to control the regulation device 101 according to the structure (type) and operation settings of the regulation device 101 in an elevator installed on a specific floor without forcing an operator to perform complicated setting work. Become.

In the present embodiment, the call registration process, the acquisition process, and the update process are executed by the call registration processing unit 104A, the acquisition processing unit 104B, and the update processing unit 104C configured in the group management control device 104, respectively (FIG. FIG. 1). Then, these processing units may be configured by hardware by constructing a circuit in the group management control device 104, or by causing a processing device such as a CPU included in the group management control device 104 to execute a program. It may be composed of software. Further, the program may be stored in a portable storage device (for example, a flash memory or the like) in a readable state, or is stored in a downloadable state on another server or the like, and the downloaded program is controlled by group management. It may be stored in a storage unit (not shown) of the device 104.

Hereinafter, the details of the call registration process, the acquisition process, and the update process will be described.

[2] Control processing executed by the group management control device <Call registration processing>
FIG. 4 is a flowchart showing a call registration process executed by the group management control device 104. The call registration process is started by the call registration processing unit 104A when the group management control device 104 receives information (including management information Pj, initial setting floor Fd, installation floor Fs, and device address Pa) from the security server 102. Will be done.

When the call registration process is started, the call registration processing unit 104A first makes a permission decision for the target user (the user whose permission is determined by the security server 102) that is the target of the call registration. During the predetermined period Tc up to, it is determined whether or not the permission is determined for another user whose destination direction is the same as that of the target user when viewed from the specific floor (step S201). This step S201 is a step for determining whether or not the current user is a series of users in relation to another user (that is, the previous user) for whom the permission determination has been made. Then, the predetermined period Tc is used as a judgment standard for making such a judgment (allocation judgment).

In the present embodiment, the call registration processing unit 104A sets the time when the information (received information Pr) of the target user is received from the security server 102 as the time when the permission is determined for the target user. By determining whether or not information about another user (received information Pr) has been received from the security server 102 during the predetermined period Tc up to that time, a permission decision can be made to another user. Determine if it was done.

When the call registration processing unit 104A determines in step S201 that "a permission decision has been made for another user (Yes)", the car 100 assigned to the other user stops on a specific floor. It is determined whether or not it is inside or just before arrival (step S202).

As an example, the call registration processing unit 104A stores the information of the car 100 to which the user is assigned in the storage unit (not shown) for each user whose permission is determined by the security server 102. Then, the call registration processing unit 104A identifies the car 100 assigned to the other user by referring to the information stored in the storage unit (not shown). Further, the call registration processing unit 104A acquires the operation status of the specified car 100 from the elevator control device 103 that controls the operation of the car 100. Then, the call registration processing unit 104A determines whether or not the car 100 is stopped at a specific floor or just before arrival, based on the acquired operation status of the car 100.

When the call registration processing unit 104A determines in step S202 that "the car is stopped at a specific floor or is about to arrive (Yes)", the car 100 is the same as the assigned car 100 to be determined. (Specifically, the landing call of the target user) is assigned to (step S203A).

On the other hand, the call registration processing unit 104A determines in step S201 that "permission has not been determined for another user (No)", or in step S202, "stops or arrives at a specific floor". If it is determined that "it is not immediately before (No)", the target user (specifically, the landing call of the target user) is the most suitable car in consideration of the initial setting floor Fd in the received information Pr. Allocate to 100 (step S203B).

After steps S203A and S203B, the call registration processing unit 104A displays the information (vehicle information Pg) for identifying the assigned vehicle 100 in the control device 101 specified by the device address Pa in the received information Pr. Is displayed in (step S204). As a result, the user can recognize the car 100 to be boarded by confirming the car information Pg displayed on the display device 2 when passing through the regulation device 101. In addition, the destination floor Fc1 and the management information Pj may be displayed on the display device 2 together with the car information Pg.

According to such a call registration process, a series of users who have the same destination direction when viewed from the specific floor can get on the car 100 which is stopped or just before arrival on the specific floor (use that can be boarded without interruption). Person) can be boarded. Therefore, it is possible to start the car 100 from a specific floor with the shortest possible stop time while increasing the number of passengers, and as a result, it is possible to improve the operation efficiency of the elevator.

<Acquisition process>
The acquisition process is executed by the acquisition process unit 104B for each regulatory device 101. Further, the acquisition processing unit 104B is executed for each time frame TF of a predetermined length (for example, 5 minutes) from a preset start time (for example, 8:00) to an end time (for example, 8:30). To. Here, the start time and the end time are such that the time zone (working time zone, etc.) in which the number of users passing through the regulation device 101 is the largest in a day is included between the start time and the end time. Is set to.

Specifically, each time the acquisition processing unit 104B makes a permission judgment in each combination of the regulation device 101 and the time frame TF, another permission judgment (this time permission judgment) is performed before the permission judgment (this time permission judgment). If the previous permission judgment) has been made, the time interval T from the previous permission judgment to the current permission judgment is acquired. Further, the acquisition processing unit 104B further acquires the number of users N for which the permission is determined within the time frame TF for each of the above combinations (that is, for each regulation device 101 and for each time frame TF).

FIG. 5 is a conceptual diagram showing an example of data acquired by executing the acquisition process. In FIG. 5, as data, the time interval T acquired by the acquisition processing unit 104B is shown individually, and the total value (total value Ts) is shown. Further, in FIG. 5, the three regulatory devices 101 are numbered by the numbers 1 to 3 (m = 1 to 3). Further, the time frame TF is divided into six from the start time to the end time of the acquisition process, and the six time frame TFs are numbered by numbers 1 to 6 (n = 1 to 6). The number of time frame TFs is not limited to six, and is appropriately determined depending on the time length from the start time to the end time of the acquisition process and the length of the time frame TF. Further, the number of the regulating devices 101 is not limited to three, and is appropriately determined according to the number of the regulating devices 101 installed in the elevator.

Then, in the example of FIG. 5, the number of users N was large in the third time frame TF (n = 3), and among them, the number of users N was the largest in the second regulatory device 101 (m = 2). Cases (N (1,3) = 20 persons, N (2,3) = 25 persons, N (3,3) = 22 persons) are shown.

<Update process>
The update process is executed by the update process unit 104C after the acquisition process is completed (that is, after the end time has elapsed). Specifically, the update processing unit 104C performs the following processing using the data (see FIG. 5) acquired by the acquisition processing unit 104B.

The update processing unit 104C is a combination of the regulation device 101 and the time frame TF (in the example of FIG. 5, 3 regulation devices × 6 time frames = 18 kinds of combinations. Hereinafter, the m-th regulation device 101 and the nth regulation device 101 and the nth combination. It is acquired in the combination (in the example of FIG. 5, (m, n) = (2, 3)) in which the value of the number of users N is the largest among the combination with the time frame TF (represented by (m, n)). Using the time interval T (in the example of FIG. 5, the total value Ts (2, 3) = 105 seconds of the time interval T), the predetermined period Tc, which is the determination criterion, is updated. As an example, the update processing unit 104C obtains an average value (= T / (N-1)) of the time interval T, and uses the obtained average value (in the example of FIG. 5, the average value = 4.2 seconds) for a predetermined period. Update Tc.

The update of the predetermined period Tc may be performed each time the update processing unit 104C obtains the average value of the time interval T, or is performed only when the average value satisfies a specific condition. May be good. For example, if the predetermined period Tc becomes excessive, the conditions to be regarded as a series of users become too lenient and the stop time of the car 100 becomes long, or the predetermined period Tc becomes too small. The condition is satisfied on condition that the average value of the time interval T is within a predetermined range so that the condition to be regarded as a user of the vehicle is not too strict and the number of passengers in the car 100 is not reduced. The Tc may be renewed for a predetermined period only when it is performed. At this time, the value (length) of the predetermined period Tc before the renewal is used as the lower limit value of the predetermined range so that the predetermined period Tc is not smaller than the value (length) of the predetermined period Tc before the renewal. May be good. The conditions (the above-mentioned specific conditions) that serve as a criterion for determining whether or not to renew Tc for a predetermined period are not limited to those described here, and may be appropriately changed so as to enable optimum renewal. May be good.

According to the control process described above, the predetermined period Tc (determination criterion) is automatically updated based on the time interval T (total value Ts in this embodiment) acquired by the acquisition process unit 104B. Here, the time interval T acquired by the acquisition processing unit 104B is an actually measured value of the time interval from the previous permission determination made by the regulation device 101 to the current permission determination, and the passage of the regulation device 101. It reflects the actual time required for. The structure (type) and operation settings of the regulating device 101 are likely to be reflected in the actual time required for passing through the regulating device 101. Therefore, by updating the predetermined period Tc based on the time interval T (actual measurement value) acquired by the acquisition processing unit 104B, the predetermined period Tc corresponds to the structure (type), operation setting, and the like of the regulation device 101. It becomes easy to set the optimum value (length). Therefore, in the elevator where the regulation device 101 is installed on a specific floor, the control according to the structure (type) and operation setting of the regulation device 101 (in the present embodiment, the above-mentioned call registration process) is complicatedly set. It becomes possible to do it without forcing the worker.

Further, when the value of the number of users N is large, it is assumed that the user has passed through the regulation device 101 without interruption as the passage status of the user in the regulation device 101. Then, in the present embodiment, the combination having the largest value of the number of users N is extracted as a combination that can assume the passing situation of such users. Therefore, the time interval T (actual measurement value) acquired in the extracted combination tends to approach the optimum time required for passing through the regulation device 101 in a situation where the user is not interrupted. Therefore, the predetermined period Tc, which is the determination criterion, is easily updated to the optimum value (length).

[3] Modification Example [3-1] First Modification Example In the control process described above, the update processing unit 104C is not limited to the time interval T acquired in the combination in which the value of the number of users N is the largest, but is another predetermined value. The predetermined period Tc (judgment criterion) may be updated using the time interval T acquired in the combination satisfying the conditions. Here, it is preferable that the predetermined condition is such that it can be assumed that the user will pass through the regulation device 101 without interruption if the predetermined condition is satisfied. The predetermined condition is not particularly limited, but is a condition that the number of users N is equal to or more than a predetermined value, or when the number of users N is ranked from the largest, Sp. It is possible to use the condition that it is up to the third (Sp is an integer of 1 or more).

In the example of FIG. 5, the combinations satisfying the condition that the number of users N is 20 (predetermined value = 20) or more are (m, n) = (1,3), (2,3), (3). , 3), (2,4), and (3,4). Further, the combinations satisfying the condition of being the first to the third (Sp = 3) from the top are (2,3), (2,4), and (3,3) from the top.

Then, the update processing unit 104C updates the predetermined period Tc, which is the determination standard, by using all the time intervals T acquired in the combination satisfying the above predetermined conditions. As an example, the update processing unit 104C obtains an average value using all the time intervals T, and updates Tc for a predetermined period with the obtained average value.

[3-2] Second Modification Example In the control process described above, the update processing unit 104C adds up the number of users N (m, n) for each time frame TF for all the regulating devices 101 (m = 1 to 3). The following update process may be performed using the total value Ns1 (that is, the total value of the number of users N for each time frame TF) obtained. That is, the update processing unit 104C may update the predetermined period Tc, which is the determination criterion, by using the time interval T acquired in the time frame TF in which the total value Ns1 of the time frame TF satisfies the predetermined condition. Here, the predetermined condition is not particularly limited, but when the total value Ns1 is the largest, the total value Ns1 is equal to or larger than the predetermined value, and the total value Ns1 is ranked from the largest. It is possible to use the condition that the order is from the upper 1st to the Sqth (Sq is an integer of 1 or more).

Further, in the control process described above, the update processing unit 104C is a total value Ns2 obtained by adding up the number of users N (m, n) for each regulation device 101 for all time frame TFs (n = 1 to 6). (That is, the total value of the number of users N for each regulation device 101) may be used to perform the following update processing. That is, the update processing unit 104C may update the predetermined period Tc, which is the determination criterion, by using the time interval T acquired by the regulatory device 101 in which the total value Ns2 of the regulatory device 101 satisfies the predetermined condition. Here, the predetermined condition is not particularly limited, but when the condition that the total value Ns2 is the largest, the condition that the total value Ns2 is equal to or larger than the predetermined value, and the total value Ns2 are ranked in descending order. It is possible to use the condition that the order is from the upper 1st to the Srth (Sr is an integer of 1 or more).

Then, the update processing unit 104C updates the predetermined period Tc, which is the determination criterion, by using the time frame TF that satisfies the above predetermined condition or the time interval T acquired by the regulation device 101. As an example, the update processing unit 104C obtains an average value of the time interval T, and updates Tc for a predetermined period with the obtained average value. The update processing unit 104C may update the predetermined period Tc, which is a determination criterion, by using all the time intervals T acquired by the acquisition processing unit 104B without setting any conditions.

[3-3] Third Modification Example In the control process described above, the call registration processing unit 104A assigns (call registration) to the car 100 for the user whose permission is determined by the security server 102. , The predicted time (arrival predicted time tp) at which the target user who is the target of the call registration arrives at the landing H may be calculated. Here, the estimated arrival time tp is the passage time Td set as the time required for the passage of the regulation device 101 at the judgment time t when the permission is determined for the target user, and from the regulation device 101 to the landing H. It is obtained by adding the movement time Te set as the time required for the movement of.

Then, the call registration processing unit 104A determines that the scheduled departure time tr from the specific floor of the car 100 that is stopped or is scheduled to arrive on the specific floor is earlier than the estimated arrival time tp of the user. The optimum car may be selected from the remaining car 100 excluding the ones, and the target user may be assigned to the optimum car 100.

According to the call registration process, the car 100 determined that the target user cannot arrive at the landing H by the scheduled departure time tr is excluded from the candidates for the car 100 to which the target user is assigned. Therefore, the user is assigned only to the car 100 in time for departure from the specific floor, and as a result, the user's boarding delay is less likely to occur.

On the other hand, in such a call registration process, the optimum value (length) of the transit time Td used for calculating the arrival predicted time tp (judgment criterion for the above allocation determination) is the structure (type) of the regulating device 101. Since it differs depending on the operation setting and the like, it is preferable to review it according to the structure (type) and the operation setting. Therefore, the update processing unit 104C may update the passage time Td, which is a determination criterion, by using at least a part of the time interval T acquired by the acquisition processing unit 104B, as in the above-described embodiment.

It should be noted that the update of the judgment criteria for such allocation judgment is not limited to the above-mentioned update of the predetermined period Tc and the transit time Td, and needs to be reviewed according to the structure (type) and operation setting of the regulation device 101. It can also be applied to update other criteria.

[3-4] Other Modifications The overall configuration of the elevator described above may be modified so that the regulation device 101 or the group management control device 104 authenticates the identification information Pi without providing the security server 102. In this case, the elevator may be controlled by the identification information Pi without using the management information Pj.

Further, the above-mentioned control process can be applied to an elevator equipped with only one car 100. In this case, the control process may be executed by the elevator control device 103.

The description of the embodiments described above should be considered exemplary in all respects and not restrictive. The scope of the invention is indicated by the claims, not by the embodiments described above. Furthermore, the scope of the present invention is intended to include all modifications within the meaning and scope of the claims.
