Abstract

(57) [Abstract] [Problem] Not only does the change of allocation cause confusion due to the movement of passengers, but it also imposes a heavy burden on persons with disabilities and the elderly. However, if no quota changes are made, the transport efficiency will obviously decrease. A plurality of elevators are divided into a plurality of banks each including two elevators as a set. When a hall call is generated, the hall call distribution means 12 distributes the hall call to any of the plurality of banks, and the bank name is displayed on the hall. The distributed hall calls are allocated to any of the units in the bank by the allocation means 13 and 14 for each bank, and the allocation is changed only in the bank at any time.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an elevator group management device, and more particularly to improvement of a call allocation system.

[0002]

[Prior art]

 A call assignment method is a typical example of elevator group management control. In the call assignment method, when a call is registered, the optimum elevator is selected from the elevators sharing the call and the call is assigned to the elevator.

[0003]

[Problems to be solved by the device]

 As the number of elevators increases, immediate forecasting is required to secure the travel time of passengers, which may be optimal depending on changes in the situation from the time when the optimum elevator is determined to the time when the elevator arrives. A situation occurs in which different elevators change. This is unavoidable because the calls are randomly generated and the time of occurrence cannot be predicted. Therefore, in such a case, it is possible to change the allocation each time, but if the allocation is changed, the movement of passengers will occur again. This is not only a cause of confusion and causes confusion, but it also imposes a heavy burden on the physically handicapped and elderly people when traveling. For this reason, it is common to refrain from changing quotas as much as possible, but if the quota is not changed at all, transportation efficiency will obviously decrease.

In addition, recently, all users register the destination floor at the landing, predict each round or one and a half rounds ahead each time, and instruct the passengers to get on board to wait for the average time. A method of halving the time has also appeared. However, in this case as well, the operation forecast is based on the call up to the time of registration of the call, and the situation of call generation is obviously changing at the time of one lap ahead, so it is better to change the allocation to further improve the transportation efficiency. However, with this method, it is difficult to notify the appropriate user of the allocation change because each passenger's boarding machine is different, and even if it is possible, even if there is a device to guide the boarding machine When I go back, I still get confused.

The present invention was made in order to solve such a problem, and does not cause a movement or confusion of users due to a change in allocation, and therefore an elevator in which allocation can be changed freely. It is an object of the present invention to provide a group management device.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention divides a plurality of elevators into a plurality of banks each including two sets, and when a hall call occurs, the hall call is distributed to any of the plurality of banks. It is provided with means for distributing hall calls and means for allocating the distributed hall calls to some units in each bank.

[0007]

[Embodiment of the invention]

 In the present invention, a plurality of elevators are divided into a plurality of banks each including two sets, and the names of the banks are displayed at the hall. When a hall call is generated, the hall call distribution means distributes the hall call to any of the plurality of banks, and the distributed bank name is displayed on the hall. Furthermore, the allocation means provided for each bank will allocate the hall call to any of the units in the bank, and will periodically review the allocation within that bank.

[0008]

【Example】

 Hereinafter, as one embodiment of the present invention, a case where four elevators are managed as a group will be described as an example, but of course, the present invention can be similarly applied to the case of having six or more elevators.

FIG. 2 is a plan view of the landing, and two Nos. 1 to 4 are arranged so as to face each other. Here, two units of Nos. 1 and 2 are set as a set, and the bank name is A, It is assumed that the bank name is B with two units of Units 3 and 4 as one set. HA and HB are hall call registration devices common to the four elevators. Fig. 3 is a front view of the landing on the A bank side. HL1 is a hall lantern for notifying call allocation to Unit 1 and arrival of Unit 1, HL2 is a Hall lantern for Unit 2, and HP is a bank for Units 1 and 2. It is a display plate that displays the name A, and the bank B side has the same structure.

FIG. 4 is a diagram showing details of the hall call registration devices HA and HB. HU is a hall call button in the ascending direction, HD is a hall call button in the descending direction, and UM is a hall call in the ascending direction. Is a display for displaying the bank name, and DM is a display for displaying the bank name when the hall call in the down direction is distributed. For example, if the hall call button HU in the ascending direction is pressed on the A bank side and the call is distributed to the A bank, the hall call button HU lights up and the bank name A is displayed on the display UM, and at the same time. The hall call button HU lights up on the B bank side as well, and the bank name A is displayed on the display UM to notify that the hall call for the ascending direction has been registered, and the call is distributed to the A bank. I will guide you.

FIG. 1 is a diagram showing an overall configuration for implementing the present invention. HA1 to HAn and HB1 to HBn are hall call registration devices installed at halls on the first to nth floors, respectively. Is a group management device composed of a microcomputer or the like, 11 is a hall call registration means for registering hall calls on each floor, and 12 is a hall call distribution means for distributing hall calls to either bank A or B according to the procedure described later. , 13 assigns the distributed call to any of Units 1 and 2 by the procedure described later, and assigns means for A bank which periodically reviews the assignment, and 14 also assigns means for B bank, 21 -24 are control devices for controlling the operation of Units 1 to 4, 31 to 34 are cages of Units 1 to 4, respectively, and HL1 to HL4 are allocation notifications and arrival notifications of Units 1 to 4, respectively. Whole Run It's Tan.

Next, the operation of the present invention having the above configuration will be described. FIG. 5 is a flow chart showing an example of a processing procedure relating to distribution of hall calls in the present invention, which is executed every time a new hall call is generated. In FIG. 5, first, in step S1, it is detected whether or not a new landing call is generated, and when the new landing call is generated, in step S2, the distance (considering the direction) from each unit in Bank A to the landing call is determined. Calculate the sum. Similarly, in step S3, the sum of the distances from the B-banks to the respective units is calculated, and in step S4 the two are compared. Then, the call is distributed to the bank with the smaller sum of the distances. Although the distance to the call was used here as the criterion for determining the call distribution, the call waiting time is not limited to this, and the estimated waiting time for each call or service completion time (at the destination floor (If the destination floor is already known by the method of registering), etc., etc. may be used. Further, the number of calls handled by each bank, the maximum waiting time, etc. may be used, or the calls may be distributed by the comprehensive evaluation.

When the call is distributed to one of the banks in this way, the bank name is displayed on each display of the hall call registration device, and the customer waits in front of the bank instructed according to the display. You can leave it. FIG. 6 is a flowchart showing an example of a processing procedure for allocating the distributed hall calls to the elevators in the bank, which is executed every time a new call is distributed and allocated to any of the units in the bank. Also, the call allocation is reviewed at regular intervals, and if the allocation result is different from the previous one, the allocation is changed.

In FIG. 6, first, in step S11, it is determined whether or not a hall call is newly distributed, and in step S12, it is determined whether or not a certain time has passed since the previous review. If a new call is distributed or if a certain time has passed since the previous review, a calculation for allocation is performed in step S13. In other words, all combinations when assigning the calls distributed to this bank to two elevators (each call is assigned to one of the two elevators, so if the number of calls is n, then 2). The average waiting time is calculated for each (nth power). Then, in step S14, a combination that minimizes the average waiting time is selected, and in step S15, calls are assigned according to the combination. If the allocation result is different from the previous one, the allocation will be changed.

In the above example, the average waiting time is assigned in step S13 as a reference. However, the present invention is not limited to this, and the service completion time may be used as a reference as in the case of call distribution, or It is also possible to select a combination that minimizes the maximum waiting time. Further, not all combinations may be targets of calculation, but only calls whose predicted waiting time or service completion time is a predetermined value or more may be calculated as targets of allocation change. Further, the allocation change may not be performed periodically as described above, but may be performed only when there is any change in the situation such as the occurrence of a car call or the change of the car position.

[0016]

[Effect of the invention]

 According to the present invention, the allocation is made in units of two cars and the allocation change is limited to within the two cars. Therefore, not only can the transportation efficiency be improved by the allocation change, but also the confusion caused by the allocation change. It is also suitable for use in buildings that are often used by physically handicapped persons and the elderly because the travel distance is short.
