Description
The application takes Japanese patent application 2018-112119 (application date: 2018, 6, 12) as the basis and enjoys the priority of the application. This application is incorporated by reference in its entirety.
Technical Field
Embodiments of the present invention relate to a group management control system for elevators.
Background
Nowadays, a hybrid DCS (Destination Control System) of an elevator is known. In a group management system for elevators to which this hybrid DCS is applied, there are a general floor to which a call in the vertical direction (up-down call) is input at an elevator boarding location, and an elevator boarding location destination call registration device installation floor to which a destination floor (destination call) is input at an elevator boarding location. As an example of a method for implementing the hybrid DCS, there is a method of controlling the operation of cars of a plurality of elevators by using both a 1 st allocation algorithm unit for selecting a car to be allocated to an allocation request for an up-down call in the up-down direction and a 2 nd allocation algorithm unit for selecting a car to be allocated to an allocation request for a destination call registered at a boarding location.
However, in the hybrid DCS, if car assignment to up-down calls or destination calls is performed without considering the number of users, each assignment algorithm unit assigns cars based on inaccurate assignment evaluation. Therefore, it is difficult to make the group management performance good in consideration of the average of each user.
The indices of the group management performance include a waiting time, which is a time from when a user registers a call at the elevator riding place until a car to be ridden responds at the elevator riding place, and a service time, which is a time from when a user registers a call at the elevator riding place until a car to be ridden responds at the elevator riding place and then responds at a destination floor of the user.
However, the group management system of the elevators is not necessarily able to directly evaluate these service indicators. For example, at a general floor where an up-down call is registered, it is difficult for the group management control system to grasp the number of users who get on the car or the destination floors of the users at the time of a response at the time point when the call is registered.
Disclosure of Invention
The problem to be solved by the present invention is to provide a group management control system capable of improving group management performance by calculating a "response prediction time" which is a prediction value of a time from when a call is registered to when a car responds to the call, and making an effort to evaluate the index as accurately as possible.
The elevator group management control system of the embodiment is an elevator group management control system having a 1 st assignment algorithm unit and a 2 nd assignment algorithm unit, wherein the 1 st assignment algorithm unit is an algorithm unit for selecting a car assigned to an up-down call in which one of an up direction and a down direction is registered before the elevator is taken from a plurality of cars, the 2 nd assignment algorithm unit is an algorithm unit for selecting a car assigned to a destination call in which a destination floor is registered before the elevator is taken from a plurality of cars, and an assigned call counting part calculates a weighting coefficient corresponding to the number of destination calls assigned to each car, each departure floor, and each direction and notifies the weighting coefficient to the 1 st assignment algorithm unit. In the 1 st allocation algorithm unit, the storage control unit stores and controls the weighting coefficients notified from the allocated call counting unit in the weighting coefficient storage unit. The 1 st operation prediction evaluation unit calculates an evaluation value including a response prediction time of each car, which is a time from registration of an up-down call to a predicted response, the evaluation value reflecting the weighting coefficient stored in the weighting coefficient storage unit. Then, the 1 st assigned car selection unit selects a car to be notified to the car control unit performing the operation of the car, and to which a call in the up-down direction of the elevator is assigned, based on the evaluation value of each car calculated by the 1 st operation prediction evaluation unit.
According to the group management control system for elevators configured as described above, the group management performance of the hybrid DCS can be improved.

Detailed Description
Hereinafter, a group management control system for elevators according to an embodiment will be described in detail with reference to the drawings.
[ outline of Mixed DCS ]
A hybrid DCS (Destination Control System) has a 1 st allocation algorithm unit and a 2 nd allocation algorithm unit, wherein the 1 st allocation algorithm unit selects an allocated car for an allocation request of a vertical "up-down call", and the 2 nd allocation algorithm unit selects an allocated car for an allocation request of a "Destination call" for registering a desired Destination floor at an elevator taking place. The 1 st allocation algorithm unit is a general algorithm unit that performs processing of up and down calls and car calls. The 2 nd allocation algorithm is a fully DCS algorithm that performs the processing of the destination call. Although an example, as a reference for disclosing such a hybrid DCS, japanese patent No. 5882090 is known.
In the 2 nd assignment algorithm means, when selecting an assigned car for a destination call assignment request, it is necessary to consider not only the destination call but also the registered up-down direction call and car call. When the 2 nd allocation algorithm means is modified in a program so that not only the destination call but also the vertical allocation and the car call can be processed, the types of the calls to be processed become large, and the processing procedure of the program becomes complicated. Therefore, in the hybrid DCS, calls and assignments other than the destination call are converted into a format of the destination call and processed using the 2 nd assignment algorithm unit that performs processing of the destination call as it is.
Specifically, the hybrid DCS converts the vertical allocation into a destination call to predict and evaluate the operation. The car call is a destination call which has been taken at the time of execution of the assignment process, and the operation prediction and evaluation are performed in the form of a destination call in which only the lower elevator floor is designated.
The hybrid DCS also processes the registered destination calls in the 1 st assignment algorithm unit by using an algorithm unit that can perform assignment requests of up and down calls, assignment of up and down calls, and evaluation of car calls as they are. The destination call is converted into an assignment of an up/down call and a form of a car call, and processed and evaluated. Specifically, assignment is set to the departure floor at the car to which the destination call is assigned before boarding, and a car is assigned to the destination call before boarding and disembarking, and a car call is set to the destination floor, whereby the operation prediction and evaluation are performed.
[ improvement points of Mixed DCS ]
Fig. 1 shows a diagram for explaining the improvement point of the hybrid DCS. Fig. 1 (a) to (c) show an example of a group management system of a hybrid DCS for controlling two elevators, an a-machine and a B-machine, in which 1 floor (building) is an installation floor of a destination call registration device at a boarding place and floors other than 1 floor are general floors. In the hybrid DCS, for example, as shown in fig. 1 (a), it is assumed that: when 5 users (who have not responded at the boarding location) from 1F to 5F have been assigned to the machine a on the departure base floor (HDC installation floor), a hall call of 3F-DN (Down) is registered.
At this time, when the number of users assigned by the 1F-UP (UP-link) of the machine a is not reflected in the mixed DCS that is used to select (evaluate) the assigned car, the assigned car is evaluated by, for example, a default coefficient. Thus, although the machine a is waiting for a response to the 5-bit user, it is sometimes determined that the machine a can respond by 3F-DN earlier than the machine B, and as shown in fig. 1 (B), the machine a is assigned as a car that responds to 3F-DN. In this case, the waiting time of 5 users assigned to the a-number machine at 1F becomes long, and there is a fear that the group management performance considered by the number average is deteriorated.
In contrast, in the group management control system for an elevator according to the embodiment, the number of assigned cars (or the number of assigned cars and the number of users) of 1F-UP of the a-number machine is reflected in the coefficient for selecting (evaluating) the assigned car. Thus, it can be recognized that the current a-number telephone is a response waiting for 5-bit users, and that the waiting time of 1F-UP 5-bit users becomes longer when the a-number telephone is made to respond to a 3F-DN hall call. Therefore, as shown in fig. 1 (c), the group management control system for elevators according to the embodiment assigns a B-number machine, which does not currently have a user waiting for a response, to a 3F-DN hall call. Thus, it is possible to assign a number a to 5 users of 1F-UP and assign B number B to a hall call of 3F-DN, which does not have a user waiting for a response at present, and it is possible to improve the group management performance of the hybrid DCS.
[ System constitution ]
Fig. 2 is a system configuration diagram of an elevator group management control system according to an embodiment. As shown in fig. 2, the group control system of the elevator according to the embodiment is a so-called hybrid DCS. That is, the elevator group management control system according to the embodiment includes the up-down call system 1 that operates based on the 1 st assignment algorithm unit, and the 1 st assignment algorithm unit is an algorithm unit that selects an assigned car for an up-down call registered before the elevator is taken. The group management control system for elevators according to the embodiment has a destination call system 2 that operates based on a 2 nd assignment algorithm unit, and the 2 nd assignment algorithm unit is an algorithm unit that selects an assigned car for a destination call registered before the elevator is taken.
The group management control system of an elevator according to the embodiment includes a vertical call registration device 3 installed in a hall of each floor, and a hall destination call registration device 4 installed in a hall of one or more floors.
The group management control system for elevators according to the embodiment includes an assigned call counting unit 7, a destination call conversion output unit 8, an assigned car call conversion output unit 9, an assignment output unit 10, a car state acquisition and evaluation unit 11, and an estimated boarding person number calculation unit 12.
The assigned call counting unit 7 forms a weighting factor for selecting an assigned car for a call in the up-down direction based on the number of destination calls (or the number of destination calls and the number of users) assigned to each car, each departure floor, and each direction by the destination call system 2, and notifies the weight factor to the up-down direction call system 1. The destination call conversion output unit 8 converts the assignment of the up-down call made by the up-down direction call system 1 (1 st algorithm means) into call data in the form of a destination call and notifies the destination call system 2 of the call 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 call or the car call.
The assignment output unit 10 supplies assigned car information indicating the assigned car to the individual car control unit 6 (an example of a car control unit) based on the selection result of the 1 st assigned car selection unit 25 of the up-down direction call system 1 and the selection result of the 2 nd assigned car selection unit 34 of the destination call system. The individual car control unit 6 controls the operation of the car 5 indicated by the assigned car information. Each car 5 is provided with a car operating panel 51 for inputting a destination floor.
The car state acquisition and evaluation unit 11 detects a load change that changes due to a change in the number of users in response to the car assignment. The estimated boarding passenger number calculation unit 12 calculates the estimated boarding passenger number based on load change information indicating a load change detected by the car state acquisition and evaluation unit 11. The estimated boarding population calculation unit 12 totals the calculated estimated boarding population for conditions including the day of the week and the time zone, and calculates the average of the estimated boarding population for each day of the week and time zone as the estimated boarding population for each day of the week. The estimated boarding person count calculation unit 12 notifies the calculated estimated boarding person count for each day of the week to the up-down direction call system 1 as a weighting coefficient for selecting an assigned car for the up-down direction call.
Next, the vertical calling system 1 includes a 1 st operation prediction evaluation unit 21, a weighting coefficient storage unit 22, a storage control unit 23, a vertical call registration storage unit 24, a 1 st assigned car selection unit 25, and an assigned car call storage unit 26.
The 1 st operation prediction evaluation unit 21 performs the following operation prediction: response time to each car of the floor corresponding to the assigned up-down call is predicted. In other words, the 1 st operation prediction evaluation unit 21 predicts a predicted response time, which is a time from when the up-down call is registered to when the response is predicted, in the operation prediction. The 1 st operation prediction evaluating unit 21 calculates an evaluation value (predicted response time) of each car 5 for an up-down call based on a weighting coefficient formed by the assigned call counting unit 7 based on the number of destination calls (or the number of users and the number of users) of the destination call system 2 and the result of the operation prediction.
The weighting factor storage unit 22 stores a weighting factor formed by the assigned call counting unit 7 based on the number of destination calls (or the number of users and the number of destination calls) of the destination call system 2. The storage control unit 23 stores and controls the weighting coefficients formed by the assigned call counting unit 7 in the weighting coefficient storage unit 22.
The up-down call registration storage unit 24 stores, as up-down call registration data, an up-call registration time at which an up-direction call is registered and a down-call registration time at which a down-direction call is registered, for each floor. The 1 st operation prediction and evaluation unit 21 calculates, for each car 5 corresponding to the up-down call registered in the up-down call registration storage unit 24, an evaluation value (response time) in the case where a new up-down call is assigned and an evaluation value in the case where a new up-down call is not assigned.
The evaluation value in the case where a new up-down direction call is assigned is the sum of the evaluation values of each call on average, which are obtained for both the new call and the assigned call, based on the predicted response time obtained by the operation prediction in the case where a new up-down direction call is assigned. The evaluation value in the case where no new up-down direction call is assigned is the sum of the evaluation values of each call on average, which are found for the already assigned calls, based on the predicted response time obtained by the operation prediction in the case where no new up-down direction call is assigned. As an example, the average evaluation value per call is: the value obtained by multiplying the square of the predicted value of the waiting time obtained from the predicted response time of the candidate car to be assigned to the call to the departure floor by the weighting coefficient corresponding to the departure floor/departure direction of the call.
The 1 st assigned car selection unit 25 selects, as an assigned car, a car having the smallest difference between the evaluation value when the up-down call is assigned and the evaluation value when the up-down call is not assigned (i.e., the car having the smallest load) among the cars 5, and notifies the assigned car to the assignment output unit 10.
The assigned car call storage unit 26 stores information indicating the assigned car selected by the 1 st assigned car selection unit 25 as a part of scheduled travel. Further, although not shown, when a car call button in the car 5 is operated by a user, a car call is stored in the assigned car call storage unit 26 via the individual car control unit 6. The individual car control unit 6 also 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 includes a 2 nd operation prediction evaluation unit 31, a destination call allocation storage unit (pre-boarding/post-boarding) 32, a destination call registration acquisition unit 33, and a 2 nd assigned car selection unit 34.
The destination call allocation storage unit 32 is provided with: the destination call assigned by the destination call system 2 (the call before the departure floor is responded to is "before boarding", and the call after the departure floor is responded to and before the destination floor is "after boarding"), and the call in which the assignment of the up-down call and the car call assigned by the up-down direction call system 1 are converted into the data format of the destination call. The destination call before boarding and the call after converting the assignment of the up-down call into the data format 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 call in which the assignment of the up/down call stored in the destination call assignment storage unit 32 is converted into the data format of the destination call is information in which the weighting coefficient corresponding to the estimated value of the number of users is reflected.
The destination call registration acquiring unit 33 acquires each destination floor specified (input) by each user via the hall destination call registration device 4, and notifies the 2 nd operation prediction evaluating unit 31 of the destination floor. In addition, the destination call registration acquiring unit 33 specifies a departure floor based on the installation floor of the hall destination call registration device 4 used for inputting the destination floor, and notifies the 2 nd operation prediction evaluating unit 31 of the departure floor. The destination call registration acquiring unit 33 specifies the direction of the destination call in the up direction or the down direction based on the positional relationship between the upper and lower sides of the "destination floor" and the "departure floor", and notifies the 2 nd operation prediction evaluating unit 31 of the direction. When a new destination call is expected to be used by a plurality of persons for the same destination floor, the destination call registration acquiring unit 33 notifies the 2 nd operation prediction evaluating unit 31 of information on the number of persons expected to be used, including the information.
The 2 nd operation prediction evaluation unit 31 acquires these pieces of information as a new destination call. Then, the 2 nd operation prediction and evaluation unit 31 calculates an evaluation value (response time) in the case where a new destination call is assigned and an evaluation value in the case where a new destination call is not assigned for each car 5 of the floor corresponding to the assigned destination call.
The evaluation value in the case where a new destination call is assigned is the sum of the evaluation values of the average calls for both the new call and the already assigned call, based on the predicted response time obtained by the operation prediction in the case where a new destination call is assigned. The evaluation value in the case where no new destination call is assigned is the sum of the evaluation values of the average calls per call found for the assigned calls based on the predicted response time obtained by the operation prediction in the case where no new destination call is assigned. As an example, the average evaluation value per call is: the value obtained by multiplying the square of the predicted value of the service time obtained from the predicted response time of the candidate car to the call to the departure floor and the destination floor by the number of people used corresponding to the call.
The 2 nd assigned car selection unit 34 selects, as an assigned car, a car having the smallest difference value between the evaluation value when a destination call is assigned and the evaluation value when a destination call is not assigned (i.e., a car having the smallest load) among the cars 5 that are candidates for assignment of a new destination call, notifies the assignment output unit 10 of the car having the smallest difference value, and stores the car in the destination call assignment storage unit 32.
[ System operation ]
The group management control system of the elevator of the embodiment having such a configuration stores the assignment of the up-down call to the up-down direction call system 1 side in the assigned car call storage unit 26, and the destination call conversion output unit 8 converts the assignment into information in the form of destination call information to store the information in the destination call assignment storage unit 32 of the destination call system 2. The destination call assignment storage unit 32 stores the assignment of the destination call to the destination call system 2, and the assigned car call conversion output unit 9 converts the assignment into information in the form of up/down call information and stores the information in the assigned car call storage unit 26.
The contents stored in 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 updated one after another based on the assignment of vertical calls and the assignment of destination calls, respectively. This makes it possible to synchronize 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.
In the vertical calling system 1, the operation control of the vertical call on the vertical calling system 1 side can be performed based on the assignment of the vertical call and the assignment of the destination call to both the systems 1 and 2. Similarly, in the destination call system 2, the operation control of the destination call on the destination call system 2 side can be performed based on the assignment of the up-down call and the assignment of the destination call by both the systems 1 and 2.
The contents stored in the destination call assignment storage unit 32 of the destination call system 2 and the contents stored in the assigned car call storage unit 26 of the up-down direction call system 1 are updated at the timing when the number of destination call assignments or the number of up-down call assignments change, such as when a new destination call assignment occurs or when an elevator responds.
Here, in the hybrid DCS such as the elevator group management control system of the embodiment, if the assignment of the cars 5 to the new up-down call or the new destination call is performed without considering the number of the cars (or the number of users), the assignment of the cars 5 may become inaccurate.
Therefore, in the group management control system of an elevator according to the embodiment, the destination call assigned is stored for each car, each floor, and each direction in the destination call assignment storage unit 32 of the destination call system 2 shown in fig. 2. At the same time, the weighting coefficients corresponding to the number of assigned destination calls (or the number of users and the number of cars) are stored for each car, each floor, and each direction in the weighting coefficient storage unit 22 of the vertical call system 1. Then, every time a car assignment for a new destination call is performed on the destination call system 2 side, the assigned new destination call is stored in the destination call assignment storage unit 32, and the weighting coefficient corresponding to the number of pieces (or the number of pieces and the number of users) increased by the assignment of the new destination call is calculated and updated in the weighting coefficient storage unit 22.
When the up-down direction call system 1 assigns a car to a new up-down call, the evaluation value of each car 5 is calculated using the weighting coefficient stored in the weighting coefficient storage unit 22, and the car 5 to which the new up-down call is assigned is determined based on the calculated evaluation value. This makes it possible to reflect the number of destination calls (or the number of users and the number of cars) on the evaluation value calculated to determine the car 5 to which the up-down call is assigned. Therefore, the car 5 assigned for the up-down call can be determined based on the accurate evaluation value, and excellent group management performance of the elevator can be obtained.
Hereinafter, the update process of the weighting coefficients will be described with reference to the flowchart of fig. 3. The operation of determining the car 5 to which a new up-down call is assigned based on the weighting coefficient will be described with reference to the flowchart of fig. 4.
(update processing of weighting factor)
First, the update process of the weighting coefficients will be described with reference to the flowchart of fig. 3. It is assumed that a weighting coefficient corresponding to the number of destination calls (or the number of users and the number of floors) assigned is already stored for each car, each floor, and each direction in the weighting coefficient storage unit 22 shown in fig. 2. In the flowchart of fig. 3, the destination call system 2 proceeds from step S1 to step S2 at the time of the distribution output of the destination call or at the time of the response (step S1: yes).
In step S2, the assigned car call conversion output unit 9 converts the assigned destination call into information of the up-down call format and supplies the information to the up-down call system 1. The destination call converted into the information of the up-down call format is stored in the assigned car call storage unit 26. Thus, the assigned car call storage unit 26 reflects the assigned destination call for the assigned up-down call stored for each car, each floor, and each direction.
To describe the operation of step S2 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 direction call system 1 of the divided destination calls. Thus, in the vertical call system 1, the operation control of the car can be performed in consideration of the assigned destination call. The assigned car call conversion output unit 9 acquires the "position", "direction", and "current week" of the car 5 from the car state acquisition and evaluation unit 11, converts the call determined to be able to respond within 1 week thereafter into an assignment in the up-down direction, and writes the assignment in the assigned car call storage unit 26.
When the "position", "direction", and "current week" of the assigned car obtained from the car state acquisition and evaluation unit 11 match the "departure floor", "direction", and "week" of the assigned destination call, the assigned car call conversion output unit 9 determines that the assigned destination call is responded to, generates car call data of the assigned car for the floor corresponding to the destination floor of the destination call, and notifies the assigned car call storage unit 26 of the car call data.
The "number of rounds" is a value incremented by "1" every time the car changes from the 1 st direction (for example, downward direction) to the 2 nd direction (for example, upward direction), and the initial round is the first round. The 1 st direction may be an up direction, and the 2 nd direction may be a down direction. In addition, the week that should be taken indicates that the car should be taken at the next week. That is, when the "week to be taken" coincides with the "week" of the current car, the time to be taken (week to be taken) is set as the time to be taken.
Next, in step S3, the assigned call count unit 7 shown in fig. 2 supplies the total result obtained by summing up the numbers of the assigned destination calls corresponding to the cars, floors, and directions to the vertical call system 1 as a weighting coefficient used when determining the assigned car in the vertical call system 1. The storage control unit 23 of the vertical calling system 1 updates the weighting coefficients stored in the weighting coefficient storage unit 22 for each car, floor, and direction with new weighting coefficients.
(calculation of weighting factor)
Here, a specific example of the calculation operation of the weighting factor performed by the allocated call counting unit 7 at the time of the allocation output of the destination call or the timing at the time of the response will be described. The assignment of 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 call registration device 4 is provided on level 1, and as shown in fig. 5 (b), the users assigned to the a number machine are 5 in number from level 1 to level 5 and 3 in number from level 1 to level 8. In a system in which each user inputs a destination call, the number of destination calls corresponding to 8 boarding passes in the upward direction from 1 floor is registered in the a-plane at the same time. At this time, as shown in fig. 5 (a), the assigned call counter 7 calculates a weighting coefficient of "8" for the direction on level 1 of the a-number machine.
The explanation is based on the premise that the average number of people calling each destination is 1. When the function of simultaneously registering destination calls of a plurality of users is provided in the hall call registration device 4, the assigned call count unit 7 may calculate a total value of the number of users to be added to each assigned destination call as a weighting coefficient. That is, for example, in the a-plane, assuming that 5 destination calls of 1 person from 1 floor to 5 floors and 2 destination calls of 3 persons from 1 floor to 8 floors are allocated, the allocated call count unit 7 calculates the weighting coefficient to be "(5 × 1 person) + (2 × 3 persons) ═ 11".
In any of the above cases, the assigned call counting unit 7 calculates a weighting coefficient having a larger value as the number of the users and the number of the users increase.
The weighting coefficient calculated by the assigned call counting unit 7 based on the number of destination calls (the number of users and the number of destination calls) is used in the case of evaluating the car 5 assigned to the up-down call in the up-down call system 1 as described below.
(decision work of assigned car in Up/Down Call System)
Next, the operation of the up-down direction calling system 1 for determining an assigned car for an up-down call using the above-described weighting coefficients will be described with reference to the flowchart of fig. 4. In the flowchart of fig. 4, when the up-down call is registered in the up-down call registration storage unit 24 via the up-down direction call registration device 3 shown in fig. 2 in step S1 (yes in step S11), the process proceeds to step S12.
Although not shown, in step S11, not only when a new up/down call is registered but also when an assigned call becomes unable to maintain assignment (when a failure occurs or when the assigned call needs to be changed to another car due to an excessively long waiting time), the step S11 may be advanced in the yes direction for the purpose of reassigning a car, and thereafter, evaluation may be continued using a call to be reassigned to a car instead of the new up/down call.
In step S12, the 1 st operation prediction and evaluation unit 21 performs operation prediction for predicting the response time of each car 5 for each floor shown in the operation schedule. Specifically, the 1 st operation prediction evaluating unit 21 performs two types of operation predictions for each car 5 as follows: the operation prediction in the case where a new up-down call is assigned and the operation prediction in the case where a new up-down call is not assigned are performed. Thus, the process proceeds to step S13. In step S13, the 1 st operation prediction and evaluation unit 21 reads out the weighting coefficients from the weighting coefficient storage unit 22 and acquires the weighting coefficients based on the number of destination calls (or the number of users and the number of destination calls) of the destination call system 2.
In step S14, the 1 st operation prediction and evaluation unit 21 calculates an evaluation value in consideration of the weighting coefficient for each car 5 as follows.
First, using the result of the operation prediction in the case where no new up/down call is assigned, which has been calculated in step S12, the "evaluation value in the case where no new up/down call is assigned" of each car is calculated.
As a method for this, first, a value obtained by squaring "the predicted response time required from registration of a call to response" is obtained for each assignment already registered.
Next, values corresponding to the assigned departure floor and departure direction are extracted from the weighting coefficients acquired in step S13, and the values are multiplied by the squared values to obtain evaluation values for the assignments. Therefore, the average evaluation value per call is proportional to the value of the weighting coefficient, and influences the determination of the assigned car. Next, a value obtained by summing the average evaluation values for each call for each car is obtained and stored as "an evaluation value in the case where no new up-down call is assigned".
Next, using the result of the operation prediction in the case where the new up-down call assignment has been made, which has been calculated in step S12, the "evaluation value in the case where the new up-down call assignment has been made" for each car is calculated. As a method of this, first, a value obtained by squaring "the predicted response time required from registration of a call to response" is obtained for each already registered assignment and an assumption that a new up-down call is to be assigned.
Next, values corresponding to the assigned departure floor and departure direction are extracted from the weighting coefficients acquired in step S13, and the values are multiplied by the squared values to obtain evaluation values for the assignments. Next, a value obtained by summing up the average evaluation values for each call for each car is obtained and stored as "evaluation value in the case where new up-down call assignment is performed".
Next, in step S15, the 1 st assigned car selection unit 25 detects a value of a difference between the evaluation value calculated for each car 5 when a new up-down call is assigned and the evaluation value when no new up-down call is assigned, and determines the car 5 having the minimum value of the difference as the assigned car for the new up-down call. Then, the 1 st assigned car selecting section 25 stores information indicating the determined assigned car in the assigned car call storage section 26, and notifies the assigned car call storage section 10 of the information. The assignment output unit 10 notifies the individual car control unit 6 of the determined assigned car in step S16. Thus, the selected car 5 is operated and controlled by the single car control unit 6 based on the number of destination calls (or the number of destination calls and the number of users).
By determining the assigned car for the up-down call based on the evaluation value reflecting the number of destination calls (or the number of destination calls and the number of users) and performing the operation control in this way, the car 5 to which the up-down call is assigned can be selected based on an accurate evaluation value, and good group management of the elevators can be performed.
The weighting factor obtained by the assigned call counter 7 can be reflected in the evaluation value as a weighting factor only for the floor on which the hall call registration device 4 is installed. By setting the weighting coefficients also in the general floors, it is possible to calculate a more accurate evaluation value, and further improvement in group management performance is sought.
As a method of this, there is a method of setting the weighting coefficient to a larger value as the number of persons expected to board at the time of response increases. As an example of the method, the weighting coefficient may be set to a large value in a congested time zone. In addition, the actual usage pattern of the elevator may be recorded and counted, and a weighting coefficient corresponding to the average number of passengers in a time zone may be automatically set.
Thus, the value of the weighting coefficient is increased by the assignment that the number of users riding is increased in the first response, and therefore, the car can respond to the assignment with priority, and the group management performance averaged based on the number of people can be improved.
Further, each time the assigned call counting unit 7 calculates the weighting coefficient, the coefficient may be obtained in consideration of not only the number of destination calls but also the number of people expected to get on at the time of response. On the premise that users who want to ride an elevator at the installation floor of the destination call registration device at the elevator riding place register destination calls and ride the assigned cars, there may be users who actually ride the car with the door without registering destination calls. Therefore, the number of pieces to be distributed and the number of passengers may vary. By correcting the deviation and setting a weighting coefficient corresponding to the number of persons expected to actually take the ride, it is possible to improve the group management performance.
As a method therefor, a coefficient value may be set in advance for each time period, and a value obtained by multiplying the number of destination calls by the coefficient value may be stored as a weighting coefficient in the weighting coefficient storage unit 22. Further, the actual usage pattern of the elevator may be recorded and counted, a coefficient corresponding to the average number of passengers in accordance with the time period may be obtained, and a value obtained by further multiplying the number of destination calls by the coefficient value may be stored as a weighting coefficient in the weighting coefficient storage unit 22.
Further, the weighting function in this embodiment can be realized by relatively simple modification by using the "per-floor/direction weighting function" provided by the 1 st algorithm unit as the assignment algorithm unit of the normal group management in the vertical call system 1. The floor-by-floor/direction weighting function is a function of multiplying a value calculated from the response prediction time assigned to each floor by a coefficient value determined in advance for each floor and direction to obtain an evaluation value assigned to each floor.
(processing for converting the assignment of up and down calls into a form of destination call)
Next, an operation of the group management control system for elevators according to the embodiment, in which the assignment of up/down calls is converted into a destination call format and used in the destination call system 2, will be described. As described above, the group management control system for elevators according to the embodiment converts the assignment of up/down calls into a format of a destination call by the destination call conversion output unit 8 (an example of a conversion output unit), and supplies the destination call to the destination call system 2 operated by the 2 nd assignment algorithm means.
However, on the side of the vertical call system 1, since it is difficult to detect the number of pieces (and the number of users) assigned to vertical calls, the number of pieces assigned to vertical calls is always counted as 1, and the weighting factor of the destination call is always "1".
Here, the number of persons riding in response to the up-down call differs depending on the situation. For example, immediately after the end of the next shift or the start of a lunch break, many users often board the car 5 that responds to the up-and-down call at a time. In a group management control system that does not use destination calls, it is preferable to use a weighting coefficient having a large value for assignment evaluation in a time zone, a floor, and a direction that are much used. For example, on an office floor, the weighting coefficient is set to "1" at ordinary times, and the assignment evaluation is performed with the weighting coefficient set to "3" only in the noon break and the next work time period, whereby an accurate evaluation result can be obtained.
Fig. 6 (a) and 6 (b) are diagrams showing an example of the setting content of the weighting coefficient. As shown in fig. 6 (a), this example is an example of weighting coefficients applied to weekdays on monday through friday, i.e., between 17:00 and 19: 00. In this case, as shown in fig. 6 (b), weighting coefficients of "1" are set for each layer with respect to the weighting coefficients in the upward direction of 1 to 8 layers. On the other hand, since the number of users predicted to be on duty increases, the weighting factor in the lower direction is set to a weighting factor of "3" for each layer.
As described above, as shown in fig. 6 (a), 6 (b), and 7 (a), the group management control system for elevators according to the embodiment stores in advance the weighting coefficients set according to "situation" such as day of the week, time zone, floor, and direction in the weighting coefficient storage unit 22. As shown in fig. 7 (b), when the assignment of the up-down call is converted into a destination call processed by the destination call system 2 (2 nd assignment algorithm means), the weighting coefficient is reflected.
Fig. 7 (a) shows an example in which a weighting coefficient of "3" is assigned to the machine a running from the 7 th floor downward in the next shift time period. The destination call conversion output unit 8 shown in fig. 2 converts such assignment of up and down calls into destination call data in a destination call format, and adds a weighting factor of "3" in which the number of users is evaluated as 3 persons as shown in fig. 7 (b), and stores the weighting factor in the destination call assignment storage unit 32 of the destination call system 2.
As a method of reflecting the weighting coefficient to 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 can be performed. For example, a field (field) of weighting coefficients may be newly added to the data format of the destination call data. Alternatively, the weighting coefficient may be set in a region of the number of persons or the load in a data format set in advance in the destination call data.
To be more specific, the existing assignment in the vertical direction is converted into a destination call, and information on a destination floor is required. The assignment of the assigned up-down call only has information on the departure floor and the direction of use, and therefore it is necessary to assume the destination floor.
Although this is an example, in the case of the group management control system of an elevator according to the embodiment, the farthest floor that can be reached by the elevator from the departure floor in the use direction is assumed as the destination floor. Specifically, as shown in fig. 8 (a), when the departure floor is 2 floors and the user designates an upward movement, the destination call conversion output unit 8 converts the allocation of the allocated up/down call into destination call data with 6 floors, which are the highest floors in this example, as destination floors, as shown in fig. 8 (b).
When the departure reference floor connected to the entrance of the building is located closer to the farthest floor (for example, 3 floors) when the direction of use is from the departure floor, the departure reference floor may be set as the assumed destination floor. In the first half of a lunch break, etc., the floor where the dining hall is installed may be the assumed destination floor.
The destination floor assumed in this way is used only when the operation of the elevator is predicted in the destination call system 2 (2 nd algorithm means), and the floor where the actual car moves is determined based on the "car call" (input destination floor) registered by the user operating the car call button or the like of the car operation panel 51 provided in the car 5.
The group management control system for elevators according to the embodiment can convert the assignment of the assigned up-down call into the destination call data of the destination call in such a manner that the number of users to be carried is taken into consideration. Therefore, the destination call system 2 can determine the car 5 to be assigned after more accurately evaluating each car 5 for a destination call. Therefore, the group management performance of the elevator group management control system according to the embodiment can be improved.
(learning of weighting factor)
The elevator group management control system according to the embodiment can estimate and sum the number of passengers of each car 5 based on the conditions including the day of the week and the time zone, and calculate and store the weighting coefficients for the day of the week and the time zone in the weighting coefficient storage unit 22 based on the result of the summation.
Specifically, the car state acquisition and evaluation unit 11 shown in fig. 2 acquires load information of the response period of each car 5 from the individual car control unit 6, and supplies the acquired load information to the estimated boarding count calculation unit 12. The estimated boarding count calculation unit 12 estimates the number of boarding persons based on the load information. In an example, the estimated boarding person number calculating unit 12 calculates the number of boarding persons by calculating 390 kg/65 kg to 6 persons assuming that the weight of a person is 65kg when the acquired load information is 390 kg.
The car state acquisition and evaluation unit 11 performs such estimation work of the number of passengers on a day-of-week basis and a time-of-day basis, thereby totaling the number of passengers on each day-of-week basis and each time-of-day basis. Then, an average value (other value such as a maximum value) of the number of passengers for each day of the week and for each time zone is calculated, and the average value of the number of passengers for each day of the week and for each time zone is stored and controlled as the above-mentioned weighting coefficient in the weighting coefficient storage unit 22.
The 1 st operation prediction evaluation unit 21 reads out the weighting coefficients corresponding to the day of the week and the time period from the weighting coefficient storage unit 22, and performs evaluation of each car for the above-described up-and-down call. The destination call conversion output unit 8 reads out the weighting coefficients corresponding to the day of the week and the time period from the weighting coefficient storage unit 22, and reflects the weighting coefficients in the operation of converting the up-down call into the destination call. This can further improve the group management performance of the elevator group management control system according to the embodiment.

These embodiments can be implemented in other various forms, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention.
For example, the present invention can be applied to an elevator as follows: the movement control of a plurality of cars (or three or more cars) in a connected state is performed, as in a so-called double-deck elevator or the like in which a total of two cars of a car for an odd-numbered floor and a car for an even-numbered floor above the car are connected and the movement control is performed simultaneously by one single car control unit 6. In this case, the same effects as described above can be obtained.
