Description

  The present invention relates to a group management elevator system, and more particularly, to a means for alleviating unfairness related to a user's waiting time.

  The group management elevator system is an elevator system that can provide an efficient car operation service to a user by handling a plurality of cars as one group. Specifically, a plurality of cars (usually 3 to 8 cars) are managed as one group, and when a hall call occurs on a certain floor, one optimal car is selected from this group. The control for assigning the previous hall call to the car is performed.

  The current group management elevator system is based on allocation control based on an allocation evaluation function based on predicted waiting time, and was developed around 1980 when a microcomputer was adopted. Allocation control based on the allocation evaluation function based on this estimated waiting time is to manage hall calls that have occurred from the past to the present, and when a new hall call occurs, calculate the expected waiting time for this new hall call. The control is performed to assign the hall call to the car having the minimum waiting time or the car having the minimum maximum waiting time. This control principle is an epoch-making control method at that time, and the basic principle has been inherited by the group management control of each elevator maker until now.

  In recent years, in the field of elevators, shortening waiting time has become an increasingly important technical issue, and in order to solve this, when selecting a car to which a hall call is assigned from a plurality of cars, Various proposals have been made in which various variable parameters are added to an evaluation function for evaluating a car, and variable parameter values are changed according to traffic demand (see, for example, Patent Documents 1 and 2).

  In the invention described in Patent Document 1, a zone in which hall calls are preferentially assigned to the elevator according to the position of the elevator is set, and at least the zone and a predicted waiting time for the hall call are calculated to evaluate the elevator. It is to seek an indicator. The invention described in Patent Document 2 selects at least one risk floor with a high probability that a long wait will occur from floors where a hall call is not generated when a hall call is newly generated. Assuming that hall calls have been generated on the floor where the new hall call has been generated and the risk floor, an assignment evaluation is performed when each car is assigned to each of these calls. The assigned car for the newly generated floor is determined. According to these inventions, the waiting time can be reduced and the transportation efficiency of the elevator apparatus can be improved.

Japanese Patent Laid-Open No. 1-2226676 (Claim 1) JP 2006-213445 A (Abstract)

  However, according to the inventions described in Patent Documents 1 and 2, although the overall waiting time of the elevator apparatus can be reduced, nothing is taken into account for the resolution of dissatisfaction and unfairness felt by users who have been waiting for a long time. There is room for improvement in this regard.

  That is, in the conventional group management elevator system, there is a case where a hall call is passed through a floor without assigning a hall call to the car in order to efficiently operate the car. In addition, when the car is almost full, it may be passed through the floor where the hall call was made even if there is an allocation. In such a case, the user of the passed floor suddenly encounters a long wait. On the other hand, when arriving at the elevator hall to use the elevator, there is a case where an accidental car is stopped on the floor and can be used without waiting time. In this way, the waiting time of elevators varies greatly depending on the operation status of the elevator and the timing of arrival at the elevator hall, so that a user who frequently waits for long waits as if he / she always encounters long waiting. Will have a sense of dissatisfaction and unfairness.

  The present invention has been made in view of the above-described prior art, and an object of the present invention is to provide a group management elevator system that equalizes waiting time between users and makes it difficult for users to feel dissatisfaction and unfairness. It is to provide.

In order to solve such a technical problem, the present invention manages a plurality of cars that serve a plurality of floors, manages the plurality of cars as a group, and the plurality of cars according to a user's landing call. A group management elevator system comprising: a group management control system that selects one optimal car from a car and assigns the hall call to the selected one car; Based on the past average waiting time or maximum waiting time , hall call information and operation information of the plurality of cars, an assigned evaluation value is calculated for each of the plurality of cars, and the car with the smallest assigned evaluation value is calculated. The hall call is assigned to.

  According to the present invention, the assigned evaluation value for each car is calculated in consideration of the user's past waiting time information, and the car having the smallest assigned evaluation value is assigned to the hall call. It is possible to equalize and alleviate user dissatisfaction and unfairness regarding waiting time.

As shown in FIG. 2, the mobile terminal 10 includes, as information transmitted to and received from the mobile terminal reader 82, registered floor information 10a indicating, for example, a lobby floor, and destination floor information 10b indicating, for example, a work floor. And the past waiting time information 10c is stored. In the present specification, the registered floor information 10a and the destination floor information 10b are collectively referred to as “hall call information”. As the waiting time information 10c in the past, an average waiting time or a maximum waiting time can be stored. In addition to the above-described information 10a, 10b, 10c, the mobile terminal 10 can also store special call information such as a wheelchair-only landing call.

  When the information transmission path is connected to the portable terminal 10, the portable terminal reader 82 transmits the previous waiting time information to the portable terminal 10, and then the registered floor information 10 a and the destination floor information 10 b from the portable terminal 10. And the past waiting time information 10c is read. These controls are performed by the elevator control device 1.

  Returning to FIG. 1, the elevator control device 1 includes a group management control device 2 and the same number of car control devices 31, 32, and 33 (three in the present embodiment). The group management control device 2 selects a car to be assigned to the hall call, lifts and lowers the cars 41, 42, and 43, drives the car position display devices 61, 62, and 63 and halls through the machine control devices 31, 32, and 33. The drive of the lanterns 94, 95, 96 is controlled. Further, the destination floor information output from the destination floor registration devices 51, 52, 53 and the load information output from the load sensors 71, 72, 73 are used as car information via the machine control devices 31, 32, 33. It transmits to the elevator control device 1.

  As shown in FIG. 1, the group management control device 2 includes a hall call information collection unit 21, a car information collection unit 22, a traffic information detection unit 23, a waiting time information collection unit 24, and an assigned elevator selection unit 26. I have.

  The hall call information collecting unit 21 stores in advance identification information of the mobile terminal reading device 82 installed on each floor, and each time information is read from the mobile terminal 10 by the mobile terminal reading device 82, the mobile terminal The registered floor information 10a and the destination floor information 10b read from 10 are registered. As described above, the registered floor information 10a is, for example, a lobby floor, and the destination floor information 10b is, for example, a work floor. Therefore, the group management control device 2 uses the identification information of the portable terminal reading device 82 stored in the hall call information collecting unit 21 and the registered floor information 10a and the destination floor information 10b read from the portable terminal 10 to obtain a landing. A distinction can be made between calling and rising or falling.

  In the car information collection unit 22, information on the operation status of the car, such as the position of each car 41, 42, 43, the moving direction, the degree of congestion in the car, and the like transmitted from the respective car control devices 31, 32, 33 is registered. The

  Based on the information registered in the hall call information collection unit 21 and the information registered in the car information collection unit 22, the traffic information detection unit 23 determines the current use status of the elevator. The traffic information detection unit 23 detects a traffic flow pattern and predicts the number of users getting on and off in each floor.

  In the waiting time information collecting unit 24, past waiting time information 10c read from the portable terminal 10 by the portable terminal reading device 82 is registered.

  When a new hall call is generated, the assigned elevator selection unit 26 assigns the hall based on the information registered in the hall call information collection unit 21, the car information collection unit, the traffic information detection unit 23, and the waiting time information collection unit 24. The evaluation value is calculated, and the new hall call is assigned to a car that can equalize the waiting time of each user.

  Hereinafter, the selection process of the cars 41, 42, and 43 performed by the assigned elevator selection unit 26 will be described.

  FIG. 3 shows an example of a waiting situation on each floor when a new hall call is generated. In this example, 5 people are waiting for the ascending car on the 1st floor (1F), 1 person is waiting for the ascending car on the 2nd floor (2F), and 2 people are on the 3rd floor (3F). One person is waiting for the car in the upward direction, and one person is waiting for the car in the downward direction on the 9th floor (9F). Each user's past waiting time information is read by the mobile terminal reader 82 from the mobile terminal 10 carried by each user, and waiting for the user waiting for the car in the upward direction of each floor and the car in the downward direction. The average value of the past waiting times is calculated for each user, and is stored in another table of the waiting time information collection unit 24. The squares in FIG. 3 indicate past waiting time information for each user. Note that the average waiting time can be used as the past waiting time information, and the maximum waiting time can also be used.

  In the example of FIG. 3, the average waiting time of five users waiting for the upward car on the first floor is 25.8 seconds, and one user waiting for the upward car on the second floor. Past waiting time is 26.1 seconds, waiting for an upward car at the 3rd floor, past average waiting time of two users is 43.5 seconds, waiting for a downward car at the 3rd floor The past waiting time of one user is 32.4 seconds, and the waiting time of one user waiting for a car in the downward direction on the 9th floor is 23.5 seconds. Therefore, in the case of this example, the car is preferentially assigned to the hall call on the third floor in both the upward direction and the downward direction. Thereby, the waiting time of each user can be equalized, and the dissatisfaction and unfairness of the user regarding the waiting time can be alleviated.

  Specifically, the selection process of the cars 41, 42, and 43 to which the hall call is assigned is performed according to the procedure shown in the flowchart of FIG. In s100, when the user connects the portable terminal 10 to the waiting time information collecting device 82 in a contact or non-contact manner, the registration read from the portable terminal 10 to the hall call information collecting unit 21 of the group management control device 2 is registered. Floor information 10a and destination floor information 10b are registered as hall call information. At the same time, the waiting time information 10 c read from the portable terminal 10 is registered in the waiting time information collecting unit 24 of the group management control device 2. In s200, the past waiting time information table (FIG. 3) is updated based on the hall call information collected in s100. In s300, an allocation evaluation value is calculated for each elevator car based on the waiting time evaluation value, the elevator state evaluation value, the past waiting time evaluation value, and the like. In s400, the respective assigned evaluation values are compared, and the assignment is made to the smallest elevator. In s500, an allocation signal is transmitted to the required number controller 31, 32, 33. Thereby, each of the cars 41, 42, 43 is driven in a required operation pattern.

  Hereinafter, how to obtain a past waiting time evaluation value will be described with reference to FIG. In the example of FIG. 5, the symbol H100 represents an allocation target call, and the symbols H101 to H103 represent already allocated calls. The allocation target call H100 is a down call from the 8th floor, and the user's past waiting time is 25.3 seconds. Allocated call H101 is an up call from the 6th floor, and the user's past waiting time is 26.5 seconds. Allocated call H102 is a down call from the 5th floor, and the user's past waiting time is 35.0 seconds. Allocated call H103 is a down call from the second floor, and the user's past waiting time is 15.8 seconds. The car 41 is traveling up the third floor. In this case, the already assigned call of H101 is not considered because it is not affected even if the call of H100 is assigned. The past waiting time evaluation value is used for the already assigned calls of H102 and H103. There are two methods for calculating the past waiting time evaluation value, for example, a method using the larger of the past average waiting times of H102 and H103, and a method of averaging the past average waiting times of each square. Therefore, in the example of FIG. 5, the car 41 is assigned to the already assigned call of H102.

  The group management elevator system according to the present embodiment uses the mobile terminal reading device 82 provided at the hall to store the past waiting time information 10c and the hall call information 10a and 10b stored in the mobile terminal 10 carried by the user. Each user reads the information and calculates the assigned evaluation value for each car based on the operation information of the plurality of cars 41, 42, 43, and assigns the car having the smallest assigned evaluation value to the hall call. The waiting time can be equalized, and the dissatisfaction and unfairness of the user regarding the waiting time can be alleviated. Moreover, in this embodiment, since it is not necessary to equip the elevator control apparatus 1 with the memory | storage device for memorize | storing each user's past waiting time information 10c and hall call information 10a, 10b, the structure of the elevator control apparatus 1 Can be simplified, and the cost can be reduced.

  In addition, in order to enable the use of an elevator even for a person who does not carry a mobile terminal, a call button for a user to manually make a landing call can be installed at a landing on each floor.
