An allocated call counting unit calculates a weighting coefficient corresponding to the number of allocated calls for each car of a destination call, each departure floor, and each direction, and notifies the weighting coefficient to the first allocation algorithm. The first allocation algorithm causes a first operation prediction evaluation unit to calculate an evaluation value including predicted response time of each car from registration of the vertical all to an expected response by reflecting the weighting coefficient. A first allocated car selection unit selects an allocated car to be notified to a control unit that operates the car among a plurality of cars in response to the elevator vertical call on the basis of the evaluation value of each car calculated by the first operation prediction evaluation unit.SELECTED DRAWING: Figure 2

Description

  Embodiments of the present invention relate to an elevator group management control system.

  Today, hybrid DCSs (Destination Control Systems) for elevators are known. The elevator group management system to which the hybrid DCS is applied has a general floor for inputting a vertical call (vertical call) at a landing, and a landing destination call registration device installation floor for inputting a destination floor (destination call) at the landing. . As an example of a method of realizing a hybrid DCS, a first allocation algorithm for selecting a car to be allocated to an up / down call allocation request in a vertical direction, and a second selection of a car to be allocated to a destination call allocation request registered at a landing. There is a method of controlling the operation of a plurality of elevator cars by using the above-mentioned assignment algorithm in combination.

  However, in the hybrid DCS, if a car is assigned to an up / down call or a destination call without considering the number of users, each car assigns a car based on an incorrect assignment evaluation. For this reason, it is difficult to improve the group management performance when the average is considered for each user.

  The group management performance index includes a waiting time from when a user registers a call at the landing to when the car to be boarded answers at the landing, and when the user registers a call at the landing and then boarding. There is a service time or the like which means that a power car responds at the landing and then responds at the destination floor of the user.

  However, the elevator group management system cannot always directly evaluate these service indices. For example, on a general floor where upper and lower calls are registered, it is difficult for the group management control system to know the number of users who get into the car or the destination floor of each user when answering, at the time when the call is registered. .

  The group management control system calculates a "response prediction time", which means a predicted value of the time from when the call is registered until the car responds to the call, and evaluates the above index as accurately as possible. Efforts can improve group management performance.

In the first allocation algorithm, the storage control unit stores and controls the weighting factor notified from the allocated call counting unit in the weighting factor storage unit. Further, the first operation prediction evaluation unit is an evaluation value including a response prediction time of each car, which is a time from the registration of the up-down call to the expected response, and the weighting coefficient stored in the weighting coefficient storage unit.

  Hereinafter, an elevator group management control system according to an embodiment will be described in detail with reference to the drawings.

[Overview of Hybrid DCS]
A hybrid DCS (Destination Control System) is a first allocation algorithm for selecting an assigned car in response to an allocation request for a vertical "up / down call", and a "destination floor" in which a desired destination floor at a landing is registered. A second assignment algorithm for selecting an assigned car in response to an assignment request of "call". The first assignment algorithm is a normal algorithm that processes up / down calls and car calls. The second allocation algorithm is a full DCS algorithm that performs destination call processing. As an example, Japanese Patent No. 5882090 is known as a reference which discloses such a hybrid DCS.

  In the second assignment algorithm, when selecting an assigned car in response to an assignment request for a destination call, it is necessary to consider not only the destination call but also the registered vertical calls and the car call. If the program is modified so that the second allocation algorithm can process not only destination calls but also vertical allocation and car calls, the types of calls to be processed increase, and the processing procedure of the program becomes complicated. Become. Therefore, in the hybrid DCS, calls and assignments other than the destination call are converted to the destination call format and processed using the second allocation algorithm for processing the destination call as much as possible.

  Specifically, the hybrid DCS converts the allocation in the vertical direction into a destination call, and performs operation prediction and evaluation. The car call performs the operation prediction and the evaluation as the destination call already boarded at the time of performing the allocation processing, and in the form of the destination call designating only the landing floor.

  Further, the hybrid DCS also processes the registered destination call by using, in the first allocation algorithm, an allocation request for an up / down call and an algorithm capable of allocating the up / down call and evaluating the car call. The destination call is processed and evaluated after being converted into an upper and lower call assignment and a car call format. To be more specific, set the assignment on the departure floor with the assigned car for the destination call before boarding, and set the car call on the destination floor with the assigned car for the boarded and pre-discharged destination call, and perform operation prediction and evaluation. Do.

[Improvements in hybrid DCS]
Here, FIG. 1 shows a diagram for describing an improvement of the hybrid DCS. FIGS. 1A to 1C show a group of hybrid DCSs that control two elevators, A and B, where the first floor is a floor on which a landing destination call registration device is installed and the other floors are general floors. An example in a management system is shown. In the hybrid DCS, for example, as shown in FIG. 1 (a), at the departure reference floor (HDC installation floor), when five users heading from 1F to 5F have been assigned to the A car (no response to the landing) Assume that a hall call of 3F-DN (Down) has been registered.

  At this time, in the case of a hybrid DCS in which the number of users for the 1F-UP allocation of the A-unit is not reflected in the coefficient used for selecting (evaluating) the allocated car, for example, the allocated car is evaluated using a default coefficient. As a result, it is determined that car A can respond with 3F-DN earlier than car B, even though car A is waiting for a response to five users, as shown in FIG. 1 (b). May be assigned as a car that responds to 3F-DN. In this case, since the waiting time of the five users assigned to the car A in the first floor becomes longer, there is a concern that the group management performance, which is considered in terms of the number of people on average, will deteriorate.

  On the other hand, in the elevator group management control system of the embodiment, the number (or the number and the number of users) of the 1F-UPs of the car A is reflected in the coefficient used for selecting (evaluating) the assigned car. . As a result, the car A recognizes that it is currently waiting for a response to the five users, and when the car A responds to the hall call of the 3F-DN, the five users of the 1F-UP It can be recognized that the waiting time is longer. For this reason, the elevator group management control system according to the embodiment allocates the B car to which a user waiting for a response does not currently exist for the 3F-DN hall call as shown in FIG. 1C. As a result, car A can be assigned to five users on 1F-UP, and car B can be assigned to a hall call on 3F-DN where no user is currently waiting for a response. The group management performance of the DCS can be improved.

[System configuration]
FIG. 2 shows a system configuration diagram of the elevator group management control system of the embodiment. As shown in FIG. 2, the elevator group management control system according to the embodiment is a so-called hybrid DCS. That is, the elevator group management control system of the embodiment includes the vertical call system 1 that operates based on the first allocation algorithm that selects an allocated car for the vertical call to be registered before entering the elevator. I have. In addition, the elevator group management control system according to the embodiment includes a destination call system 2 that operates based on a second allocation algorithm for selecting an assigned car for a destination call registered before getting into the elevator.

  In addition, the elevator group management control system of the embodiment has a vertical call registration device 3 provided in each floor hall and a landing destination call registration device 4 provided in one or more floor halls. are doing.

  The elevator group management control system according to the embodiment includes an assigned call counting unit 7, a destination call conversion output unit 8, an allocated car call conversion output unit 9, an allocation output unit 10, a car state acquisition evaluation unit 11, and a boarding estimation. It has a number calculation unit 12.

  The assigned call counting unit 7 assigns the assigned car to the call in the vertical direction based on the number of destination calls (or the number and the number of users) assigned by the destination call system 2 for each car, each departure floor, and each direction. A weighting coefficient for selection is formed and notified to the vertical calling system 1. The destination call conversion output unit 8 converts the allocation of the up / down calls formed by the up / down call system 1 (first algorithm) into call data in a destination call format and notifies the destination call system 2 of the assignment data. The assigned car call conversion output unit 9 converts the destination call assigned by the destination call system 2 into a vertical call or a car call and notifies the vertical call system 1 of the converted destination call.

  The allocation output unit 10 determines a car to be allocated based on the selection result of the first allocation car selection unit 25 of the vertical call system 1 and the selection result of the second allocation car selection unit 34 of the destination call system. The assigned car information shown is supplied to the single car control unit 6 (an example of the car control unit). The single car control unit 6 controls the operation of the car 5 indicated by the assigned car information. In each car 5, a car operation panel 51 for inputting a destination floor is provided.

  The car state acquisition and evaluation unit 11 detects a change in load that changes as the car responds to the allocation and the number of users changes. The estimated number of passengers calculating section 12 calculates the estimated number of passengers based on the load change information indicating the load change detected by the car state acquisition and evaluation section 11. Further, the estimated number of boarding persons calculating section 12 totals the calculated number of estimated boarding persons under the condition including the day of the week and the time slot, and calculates the average value of the estimated number of boarding persons by the day of the week and the time slot as the estimated number of boarding persons by the day and time slot. . The estimated number of boarding persons calculating unit 12 notifies the vertical calling system 1 of the calculated estimated number of boarding persons for each day of the week as a weighting factor for selecting an assigned car for the vertical call.

  Next, the vertical call system 1 includes a first operation prediction evaluation unit 21, a weighting coefficient storage unit 22, a storage control unit 23, a vertical call registration storage unit 24, a first assigned car selection unit 25, and an assigned car call storage. It has a part 26.

  The first operation prediction evaluation unit 21 performs an operation prediction for estimating the response time of each car to the floor corresponding to the assigned upper and lower calls. In other words, the first operation prediction evaluation unit 21 predicts a predicted response time, which is a time from when an up / down call is registered to when a response is expected in the operation prediction. Then, the first operation prediction evaluation unit 21 assigns the weighting coefficient formed by the assigned call counting unit 7 based on the number of destination calls of the destination call system 2 (or the number of cases and the number of users), and the aforementioned operation Based on the result of the prediction, the evaluation value (predicted response time) of each car 5 for the up and down calls is calculated.

  The weighting coefficient storage unit 22 stores a weighting coefficient formed by the assigned call counting unit 7 based on the number of destination calls of the destination call system 2 (or the number of cases and the number of users). The storage control unit 23 stores and controls the above-mentioned weighting coefficients formed by the allocated call counting unit 7 in the weighting coefficient storage unit 22.

  The up / down call registration storage unit 24 stores, for each floor, an up call registration time at which an up call is registered and a down call registration time at which a down call is registered as up / down call registration data. The first operation prediction evaluation unit 21 evaluates (response time) when a new vertical call is assigned to each car 5 corresponding to the vertical call registered in the vertical call registration storage unit 24. And an evaluation value when no vertical call is assigned.

  The evaluation value when a new vertical call is assigned is calculated for both the new call and the assigned call based on the predicted response time obtained in the operation prediction when a new vertical call is assigned. In addition, the sum of the evaluation values per call. The evaluation value when no new vertical call is assigned is calculated for each assigned call based on the predicted response time obtained in the operation prediction when no new vertical call is assigned. The sum of the evaluation values. The evaluation value per call is, for example, a value obtained by squaring the predicted waiting time obtained from the predicted response time of the candidate car to be assigned to the departure floor of the call, and the departure floor and departure direction of the call. Is multiplied by a weighting coefficient corresponding to.

  The first assigned car selection unit 25 selects the car having the smallest difference between the evaluation value of each car 5 when the vertical call is allocated and the evaluation value when the vertical call is not allocated. (= The car with the least burden) is selected as the assigned car, and the assigned output unit 10 is notified.

  The assigned car call storage unit 26 stores information indicating the assigned car selected by the first assigned car selection unit 25 as a part of the operation schedule. Although not shown, when the user operates the car call button in the car 5, the car call is stored in the assigned car call storage unit 26 via the single car control unit 6. The single car control unit 6 controls the operation of the corresponding car 5 in accordance with the car call stored in the assigned car call storage unit 26.

  Next, the destination call system 2 has a second operation prediction evaluation unit 31, a destination call assignment storage unit (before and after boarding) 32, a destination call registration acquisition unit 33, and a second assigned car selection unit 34.

  The destination call assignment storage unit 32 stores destination calls that have been assigned by the destination call system 2 (calls before answering at the departure floor are “before boarding”, and calls after answering at the departure floor before answering at the destination floor are “after boarding” ), The assignment of the up / down call already assigned by the up / down call system 1 and the data obtained by converting the car call into the data form of the destination call are set. The destination call before boarding and the assignment of the upper and lower calls converted into the data form of the destination call are stored for each car, each floor, and each direction. The destination call after boarding is stored for each car and each floor. As will be described later, the assignment of the upper and lower calls stored in the destination call assignment storage unit 32 converted into the data form of the destination call is the information in which the weighting coefficient corresponding to the estimated value of the number of users is reflected. Has become.

  The destination call registration acquisition unit 33 acquires each destination floor designated (input) by each user via the landing destination call registration device 4 and notifies the second operation prediction evaluation unit 31 of the destination floor. Also, as an example, the destination call registration acquisition unit 33 specifies the departure floor based on the installation floor of the landing destination call registration device 4 used for inputting the destination floor, and sends the second operation prediction evaluation unit 31 Notice. Further, the destination call registration acquisition unit 33 specifies the direction of the upward or downward destination call based on the upper and lower positional relationships of the “destination floor” and the “departure floor”, and the second operation prediction evaluation unit 31. Notify Furthermore, when the new destination call expects the use of a plurality of persons for the same destination floor, the destination call registration acquisition unit 33 includes the second operation prediction evaluation including information on the number of persons expecting the use. Notify section 31.

  The second operation prediction evaluation unit 31 acquires these pieces of information as a new destination call. Then, the second operation prediction evaluation unit 31 does not assign an evaluation value (response time) and a destination call when a new destination call is assigned to each car 5 for the floor corresponding to the assigned destination call. The evaluation value of the case is calculated.

  The evaluation value when a new destination call is assigned is the call obtained for both the new call and the assigned call based on the predicted response time obtained in the operation prediction when the new destination call is assigned. It is the sum of the evaluation values for one case. The evaluation value when no new destination call is assigned is the evaluation value per call obtained for the assigned call based on the predicted response time obtained in the operation prediction when the new destination call is not assigned. Sum. The evaluation value per call corresponds to, for example, a value obtained by squaring the predicted value of the service time obtained from the predicted response time of the car to be assigned to the departure floor and the destination floor of the call. The value is multiplied by the number of users.

  The second assigned car selecting unit 34 determines the difference between the evaluation value when the destination call is allocated and the evaluation value when the destination call is not allocated among the cars 5 that are candidates for the allocation of the new destination call. The car with the smallest value (the car with the least burden) is selected as the assigned car, notified to the assignment output unit 10, and stored in the destination call assignment storage unit 32.

[System operation]
The elevator group management control system according to the embodiment having such a configuration stores the assignment of the up / down call on the side of the up / down direction call system 1 in the assigned car call storage unit 26 and the destination call conversion output unit 8 to output the destination call. And stored in the destination call assignment storage unit 32 of the destination call system 2. In addition, the assignment of the destination call in the destination call system 2 is stored in the destination call assignment storage unit 32, and the assigned car call conversion output unit 9 converts the information into information in the form of upper and lower calls and assigns the assigned car call storage unit 26. To memorize.

  The storage contents of the assigned car call storage unit 26 of the vertical call system 1 and the destination call assignment storage unit 32 of the destination call system 2 are sequentially updated based on the assignment of the vertical call and the assignment of the destination call. Thus, the assigned car call storage unit 26 of the vertical call system 1 and the destination call assignment storage unit 32 of the destination call system 2 can be synchronized.

  Then, in the up / down call system 1, the up / down call operation of the up / down call system 1 can be controlled based on the up / down call assignment and the destination call assignment of the two systems 1 and 2. Similarly, in the destination call system 2, the operation control of the destination call on the side of the destination call system 2 can be performed based on the assignment of the upper and lower calls and the assignment of the destination call of both systems 1 and 2.

  The storage contents of the destination call assignment storage unit 32 of the destination call system 2 and the storage contents of the assigned car call storage unit 26 of the up / down call system 1 are determined when an assignment of a new destination call occurs or when the elevator responds. It is updated when the number of assignments of destination calls or the number of assignments of upper and lower calls changes.

  Here, in the hybrid DCS such as the elevator group management control system of the embodiment, when the car 5 is assigned to a new up / down call or a new destination call without considering the number of cases (or the number of users). , The assignment of the car 5 may be incorrect.

  For this reason, in the elevator group management control system of the embodiment, the assigned destination calls are stored in the destination call assignment storage unit 32 of the destination call system 2 shown in FIG. 2 for each car, each floor, and each direction. At the same time, a weighting coefficient corresponding to the number of assigned destination calls (or the number and the number of users) is stored in the weighting coefficient storage unit 22 of the vertical call system 1 for each car, each floor, and each direction. . Each time a car is assigned to a new destination call on the side of the destination call system 2, the new destination call to which this assignment has been made is stored in the destination call assignment storage unit 32, and the new destination call is stored. A weighting coefficient corresponding to the number of cases (or the number of cases and the number of users) that is increased by the allocation is calculated, and the weighting coefficient storage unit 22 is updated.

  When a car is assigned to a new up / down call of the up / down call system 1, an evaluation value of each car 5 is calculated using the weighting coefficient stored in the weighting coefficient storage unit 22, and based on the calculated evaluation value, The car 5 to which a new call is assigned is determined. As a result, the number of destination calls (or the number of users and the number of users) can be reflected in the evaluation value calculated for determining the car 5 to be assigned to the upper and lower calls. For this reason, it is possible to determine the car 5 to be assigned to the upper and lower calls based on the accurate evaluation value, and it is possible to obtain good group management performance of the elevator.

  Hereinafter, the updating process of the weighting coefficient will be described with reference to the flowchart of FIG. The operation of determining the car 5 to be assigned to a new up / down call based on the weighting coefficient will be described with reference to the flowchart of FIG.

(Update processing of weighting coefficient)
First, the updating process of the weighting coefficient will be described with reference to the flowchart of FIG. The weighting coefficient storage unit 22 shown in FIG. 2 stores weighting coefficients corresponding to the number of assigned destination calls (or the number of cases and the number of users) for each car, each floor, and each direction. I do. In the flowchart of FIG. 3, when the destination call system 2 is in the output state or the response state of the destination call (step S1: Yes), the process proceeds from step S1 to step S2.

  In step S <b> 2, the assigned car call conversion output unit 9 converts the assigned destination call into information in the form of upper and lower calls and supplies the information to the upper and lower call system 1. The destination call converted into the information of the up / down call form is stored in the assigned car call storage unit 26. As a result, the assigned destination call is reflected on the assigned upper and lower calls stored in the assigned car call storage unit 26 for each car, each floor, and each direction.

  The operation in step S2 will be described in more detail. The assigned car call conversion output unit 9 divides the assigned destination call into an up / down call and a car call and notifies the up / down call system 1. As a result, in the vertical call system 1, the operation of the car can be controlled in consideration of the assigned destination call. The assigned car call conversion output unit 9 acquires the “position”, “direction”, and “current lap” of the car 5 from the car state acquisition and evaluation unit 11, and outputs a call determined to be able to respond within one lap in the future. The data is converted into an allocation in the up-down direction and written into the allocated car call storage unit 26.

  In addition, the assigned car call conversion output unit 9 sets the “position”, “direction”, and “current lap” of the assigned car obtained from the car state acquisition evaluation unit 11 as “departure floor”, “ If the directions match the direction and the circumference, it is determined that the assigned destination call has been answered, and the car call data of the assigned car is generated on the floor corresponding to the destination floor of the destination call, and the assigned car call storage unit. Notify 26.

  The “circumference” is a value that counts up “one” each time the car changes from a first direction (for example, downward) to a second direction (for example, upward). Is the first lap. The first direction may be an upward direction, and the second direction may be a downward direction. Further, the lap to be boarded indicates on what lap the car should be boarded. That is, when the “lap to be boarded” matches the “lap” of the current car, it is the time (lap) to be boarded.

  Next, in step S3, the assigned counting unit 7 shown in FIG. 2 uses the first up / down direction call system 1 to sum up the results of counting the numbers of the assigned destination calls corresponding to the car, floor, and direction. The weight is supplied to the vertical call system 1 as a weighting coefficient used when determining the assigned car. The storage control unit 23 of the vertical call system 1 updates the weighting factors stored in the weighting factor storage unit 22 for each car, floor, and direction with new weighting factors.

(Calculation operation of weighting coefficient)
Here, a specific example of the calculation operation of the weighting coefficient executed by the assigned counting unit 7 at the time of assignment output or answering of the destination call will be described. A plurality of destination calls can be output simultaneously for the same car, the same floor, and the same direction of use.

  For example, the hall destination call registration device 4 is installed on the first floor, and as shown in FIG. 5 (b), among the users assigned to the car A, five users go from the first floor to the fifth floor. It is assumed that three users go from the first floor to the eighth floor. In the case of a system in which each user inputs a destination call, the number of destination calls corresponding to boarding from the first floor upward in the A-car A is registered at the same time. At this time, the assigned counting unit 7 calculates the weighting coefficient for the first floor on the A-th car as “8” as shown in FIG. 5A.

  This description is based on the assumption that the number of persons per destination call is one. When the hall destination call registration device 4 is provided with a function of registering destination calls of a plurality of users at the same time, the assigned counting unit 7 calculates the total value of the number of users added to each assigned destination call. May be calculated as a weighting coefficient. That is, for example, five destination calls for one person going from the first floor to the fifth floor and two destination calls for three people going from the first floor to the eighth floor have already been allocated to Unit A. Then, the allocated counting unit 7 calculates a weighting coefficient of “(5 × 1) + (2 × 3) = 11”.

  In any of the above cases, the allocated counting unit 7 calculates a weighting coefficient having a larger value as the number of cases and the number of users increase.

  The weighting factor calculated by the allocated counting unit 7 based on the number of destination calls (number of cases and number of users) as described above is allocated to the upper and lower calls in the vertical call system 1 as described below. Is used when evaluating the car 5 that performs the following.

(Determining the assigned car in the vertical calling system)
Next, an operation of determining a car to be assigned to an up / down call performed by the up / down call system 1 using the above-mentioned weighting coefficient will be described with reference to a flowchart of FIG. In the flowchart of FIG. 4, when an up / down call is registered in the up / down call registration storage unit 24 via the up / down call registration device 3 shown in FIG. 2 in step S1 (step S11: Yes), the process proceeds to step S12. move on.

  Although not shown, in step S11, not only when a new up / down call is registered, but also when the allocated call cannot maintain the allocation (when a failure occurs or the waiting time is too long, Also, when it is necessary to change the allocation of another car, the process proceeds to step S11 in the direction of Yes for the purpose of reviewing the allocated car, and thereafter, the call for reviewing the allocated car is replaced with a new call for the upper and lower calls. Can be used to continue the evaluation.

  In step S12, the first operation prediction evaluation unit 21 performs an operation prediction for estimating the response time of each car 5 for each floor indicated by the operation schedule. Specifically, the first operation prediction evaluator 21 performs both operation prediction when the new upper and lower calls are allocated and operation prediction when the new upper and lower calls are not allocated. Is performed for each car 5. Thereby, the process proceeds to step S13. In step S <b> 13, the first operation prediction evaluation unit 21 reads out the weighting coefficient formed based on the number of destination calls of the destination call system 2 (or the number of cases and the number of users) from the weighting coefficient storage unit 22 and acquires the weighting coefficient. I do.

  In step S14, the first operation prediction evaluation unit 21 calculates an evaluation value for each car 5 in consideration of the weighting coefficient as described below.

  First, the “evaluation value when no new up / down call is assigned” is calculated for each car using the result of the operation prediction when the new up / down call is not assigned, which has been calculated in step S12. I do.

  As a method, first, a value obtained by squaring “predicted response time expected to be required from call registration to answer” for each registered assignment is obtained.

  Next, from the weighting coefficients obtained in step S13, values corresponding to the departure floor and departure direction of the allocation are extracted, and multiplied by the squared value to obtain an evaluation value for the allocation. Therefore, the evaluation value per call exerts an influence on the determination of the assigned car in proportion to the value of the weighting coefficient. Next, a value obtained by summing the evaluation values per call for each car is obtained and stored as “evaluation value when new upper and lower calls are not allocated”.

  Next, the “evaluation value when new upper / lower call assignment is performed” is calculated for each car using the operation prediction result when new upper / lower call assignment is performed, which has been calculated in step S12. . As a method, first, a value obtained by squaring “predicted response time expected to be required from call registration to answer” with respect to each registered assignment and the assumption of assigning new upper and lower calls is obtained.

  Next, from the weighting coefficients obtained in step S13, values corresponding to the departure floor and departure direction of the allocation are extracted, and multiplied by the squared value to obtain an evaluation value for the allocation. Next, a value obtained by summing the evaluation values per call for each car is obtained and stored as “evaluation value when new upper and lower calls are assigned”.

  Next, in step S15, the case where the first assigned car selecting unit 25 does not assign an evaluation value calculated for each car 5 when a new up / down call is assigned and a new assigned up / down call Is detected, and the car 5 having the smallest value of the difference is determined as a car to be assigned a new upper and lower call. Then, the first assigned car selection unit 25 stores information indicating the determined assigned car in the call storage unit 26 and notifies the assignment output unit 10. The allocation output unit 10 notifies the single allocated car control unit 6 of the determined allocated car in step S16. Thereby, the operation of the car 5 selected based on the number of destination calls (or the number of cases and the number of users) is controlled by the single car control unit 6.

  In this way, by deciding the assigned car for the up and down calls based on the evaluation value reflecting the number of destination calls (or the number of cases and the number of users) and controlling the operation, the up and down calls can be performed based on the accurate evaluation value. The car 5 to be assigned can be selected, and good group management of the elevators can be performed.

  The weighting coefficient provided by the assigned call counting unit 7 can reflect the number of users as a weighting coefficient in the evaluation value only for the floor where the hall destination call registration device 4 is installed. By setting the weighting coefficient even on the general floor, it is possible to further calculate an accurate evaluation value and improve the group management performance.

  As a method for this, there is a method in which the weighting coefficient is set to a larger value as the number of persons who are expected to get on at the time of response increases. As an example of the method, the weighting coefficient may be set to a large value during a congested time zone. Alternatively, the actual use of the elevator may be recorded and statistically set, and a weighting coefficient may be automatically set according to the average number of passengers according to the time zone.

  As a result, the weighting coefficient having a larger value becomes larger as the number of users gets on the board in one response, so that the car responds preferentially, and the group management performance averaged on a per-person basis can be improved.

  When calculating the weighting coefficient, the allocated call counting unit 7 may obtain a coefficient that further considers not only the number of destination calls but also the number of persons who are expected to get in the response. On the floor where the landing destination call registration device is installed, it is assumed that each user who gets into the elevator registers the destination call and gets on the assigned car, but actually does not register the destination call, There may be users who get into the car with the door open. Therefore, there may be a discrepancy between the number of assignments and the number of passengers. By correcting the deviation and setting a weighting coefficient corresponding to the number of persons who are actually expected to get on the vehicle, it is possible to improve the group management performance.

  As a method thereof, a coefficient value may be set in advance for each time zone, and a value obtained by multiplying the number of destination calls by the coefficient value may be stored in the weighting coefficient storage unit 22 as a weighting coefficient. In addition, the actual usage of the elevator is recorded and statistic, a coefficient is calculated according to the average number of passengers according to the time zone, and the number of destination calls is further multiplied by the coefficient value. The weighting coefficient may be stored in the weighting coefficient storage unit 22.

  Note that the weighting function in such an embodiment uses the “floor / direction weighting function” provided in the first algorithm, which is the allocation algorithm of the normal group management, in the vertical call system 1. Therefore, it can be realized with a relatively simple modification. The floor / direction weighting function refers to a function of obtaining an evaluation value for each allocation by multiplying a value calculated from a response prediction time for the allocation by a coefficient value predetermined for each floor / direction.

(Process to convert the assignment of upper and lower calls to the format of destination calls)
Next, an operation of the elevator group management control system according to the embodiment in which the assignment of upper and lower calls is converted into a destination call format and used in the destination call system 2 will be described. As described above, the elevator group management control system according to the embodiment converts the upper and lower call assignment into the destination call format by the destination call conversion output unit 8 (an example of the conversion output unit), and performs the second allocation. The call is supplied to the destination call system 2 which operates by the algorithm.

  However, since it is difficult for the up / down call system 1 to detect the number of calls (and the number of users) for up / down call assignment, the number of up / down call assignments is always counted as one, and the weighting factor of the destination call is also It is always "1".

  Here, the number of people boarding when responding to a vertical call differs depending on the situation. For example, immediately after the end of working hours or immediately after the start of lunch break, many users board the car 5 responding to the up / down call at one time. In a group management control system that does not use a destination call, in the case of a busy zone, a floor, and a direction when usage is heavy, it is preferable to perform assignment evaluation using a large value weighting coefficient. For example, on the floor of an office, an accurate evaluation result can be obtained by setting the weighting coefficient to “1” usually and performing the assignment evaluation by setting the weighting coefficient to “3” only during the lunch break and the time of leaving work.

  FIGS. 6A and 6B are diagrams illustrating an example of the setting contents of the weighting coefficients. As shown in FIG. 6A, this example is an example of a weighting coefficient applied between 17:00 and 19:00, which is the time of leaving work on a weekday from Monday to Friday. In this case, as shown in FIG. 6B, as the upward weighting coefficient for the first to eighth floors, a weighting coefficient of “1” is set for each floor. On the other hand, since it is expected that the number of users who leave the office will increase, a weighting coefficient of “3” is set for each floor as the downward weighting coefficient.

  As described above, the elevator group management control system according to the embodiment includes the "day of the week, hourly zone, floor, direction, etc." as shown in FIGS. 6 (a), 6 (b) and 7 (a). The weighting coefficient set according to the “situation” is stored in the weighting coefficient storage unit 22 in advance. Then, as shown in FIG. 7B, when the allocation of the upper and lower calls is converted into the destination call processed by the destination call system 2 (second allocation algorithm), the weighting factor is reflected.

  The example of FIG. 7A shows an example in which a weighting coefficient of “3” is assigned to the A-car that operates downward from the seventh floor during the time of leaving work. The destination call conversion output unit 8 shown in FIG. 2 converts the assignment of the upper and lower calls into destination call data in a destination call format, and reduces the number of users to three as shown in FIG. 7B. A weighting coefficient of “3” to be evaluated is added and stored in the destination call assignment storage unit 32 of the destination call system 2.

  As a method of reflecting the weighting coefficient on the destination call data converted into the destination call format, any method may be used as long as the assignment evaluation according to the value of the weighting coefficient is possible. For example, a field of a weighting coefficient may be newly added to the data format of the destination call data. Alternatively, a weighting coefficient may be set in the field of the number of persons or the load provided in the data format of the destination call data in advance.

  To explain in more detail, in order to convert the already allocated in the vertical direction into a destination call, information on the destination floor is required. Since the assigned upper and lower calls only have information on the departure floor and the direction of use, it is necessary to assume a destination floor.

  As an example, in the case of the elevator group management control system of the embodiment, the farthest floor from the departure floor toward the use direction and reachable by the elevator is assumed to be the destination floor. Specifically, as shown in FIG. 8A, when the departure floor is the second floor and the user specifies an upward movement, the destination call conversion output unit 8 sets the As shown, the upper floor of this example, the sixth floor, is set as the destination floor, and the assigned upper and lower calls are converted into destination call data.

  If the departure floor is headed in the direction of use, and there is a departure reference floor connected to the entrance of the building in front of the furthest floor (for example, 3rd floor), this departure reference floor is assumed as the destination floor. Is also good. In the first half of the lunch break, the destination floor may be a floor on which a dining room is installed.

  In addition, the destination floor assumed in this way is only used when predicting the operation of the elevator in the destination call system 2 (second algorithm), and the floor where the car actually moves is determined by the user. It is determined by the “car call” (input destination floor) registered by operating the car call button of the car operation panel 51 installed in the car 5.

  The elevator group management control system according to the embodiment can convert destination call data into destination call data in consideration of the number of riders in the assigned upper and lower calls. For this reason, on the destination call system 2 side, the car 5 to be assigned can be determined after more accurately evaluating each car 5 for the destination call. Therefore, the group management performance of the elevator group management control system of the embodiment can be improved.

(Learning operation of weighting coefficient)
The elevator group management control system according to the embodiment estimates and counts the number of passengers of each car 5 based on the condition including the day of the week and the time zone, and weights coefficients for each day of the week and time zone based on the counting result. Can be calculated and stored in the weighting coefficient storage unit 22.

  Specifically, the car state acquisition and evaluation unit 11 shown in FIG. 2 acquires load information during the response of each car 5 from the single car control unit 6 and supplies the acquired load information to the estimated boarding person calculation unit 12. . The estimated number of boarding persons calculation unit 12 estimates the number of boarding persons based on the load information. As an example, when the acquired load information is 390 kg, the estimated boarding person calculating unit 12 assumes that the weight of one person is 65 kg, and calculates 390 kg ÷ 65 kg = 6 people to calculate the number of boarding persons. calculate.

  The car state acquisition evaluation unit 11 performs such an operation of estimating the number of passengers for each day of the week and for each time zone, and totals the number of passengers for each day of the week and each time zone. Then, an average value of the number of passengers by day of the week and time period (other values such as the maximum value may be used) is calculated, and the average value of the number of passengers by day of the week and time period is weighted as the above-mentioned weighting coefficient. The storage is controlled in the coefficient storage unit 22.

  The first operation prediction evaluation unit 21 reads out the weighting coefficients corresponding to the day of the week and the time zone from the weighting coefficient storage unit 22, and evaluates each car for the above-mentioned vertical call. Further, the destination call conversion output unit 8 reads out the weighting coefficients corresponding to the day of the week and the time zone from the weighting coefficient storage unit 22 and reflects the weighting coefficients on the operation of converting the upper and lower calls into the destination calls. Thus, the group management performance of the elevator group management control system according to the embodiment can be further improved.
