Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for an elevator, and particularly to improve the operation efficiency of the elevator as a whole without being uncomfortable for the user, especially during a divided express operation during congestion or a concentrated service. The present invention relates to a control device for an elevator having the notification device.

[0002]

2. Description of the Related Art Conventionally, Japanese Patent Laid-Open No. 57-85776 discloses an example of a guide device for waiting customers in a hall when performing so-called centralized service control in which a plurality of elevators are assigned to a specific floor.
The gazette discloses to notify that there is a next arrival car in order to prevent the waiting cars in the hall from being concentrated on the first arrival car. This makes it possible to equalize the number of passengers to the first-arriving car and the second-arriving car.

Japanese Unexamined Patent Publication No. 58-172174 discloses that a plurality of elevators arriving at a specific floor are notified to waiting passengers in order of priority.

[0004]

In the above-mentioned prior art, only the service performance for waiting passengers on a specific floor performing the centralized service is considered, and the operation performance of the elevators on and after the specific floor is managed. Is not considered.

For example, consider a case where a centralized service is executed on the departure standard floor during work hours. At this time, the above-mentioned JP-A-57
If the technology according to -85776 is used, it becomes possible for users to board the elevators arriving one after another evenly on the departure standard floor, and it is possible to make the congestion level inside the car uniform among the elevators. However, since the destination floor of the users in each car is not managed, duplication occurs at the stop floor of each elevator. As a result, the elevators often operate in a so-called dumpling operation state in which they are operated in a rope-like manner.

On the other hand, there is a split express operation as a control method for suppressing the operation efficiency and improving the transportation capacity during the busy hours such as the office hours. When this operation is performed, for example, 6 elevators are serviced on all floors during normal hours other than the congestion hours, but during congestion, the service floor is divided into two other than the departure standard floor, and the low-rise zone and high-rise zone are divided. The zone.
Three of the six elevators will serve the departure reference floor and the lower floors, while the remaining three elevators will serve the departure reference floor and the upper zone. During the split express operation, the user selects the elevator to board in advance according to his / her destination floor. Since the service floors are originally fixed to the low and high floors in this way, the above-mentioned dumpling operation state does not occur. However, since the service floor (service zone) of each elevator during this divided express operation is fixed, it is not possible to flexibly change the service floor (service zone) according to the situation. In addition, since the transportation efficiency of the low-rise zone and the high-rise zone of the departure standard floor to the general floor in the crowded time zone is taken into consideration, it is not possible to use this divided operation control in other time zones such as normal time zone and general floor Can not.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide an elevator control device which improves both the service performance for users and the operation efficiency of the entire elevator.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a detection means for detecting that two or more elevators arrive at a specific floor within a predetermined time, and a traffic demand for the entire elevator. A configuration comprising a traffic demand determination means for making a determination, a service floor determining means for allocating the service floor to each elevator on an ad-hoc basis, and a guide display means for displaying the service floor for each elevator to waiters in the hall Is.

[0009]

[Function] Consider a case where two or more elevators arrive at the departure standard floor while performing centralized service control on the departure standard floor during work hours. At this time, the service floor determining means in the control device determines the sharing of the car call service floors scheduled to be serviced in consideration of the hall calls and the like already assigned to the two elevators.

Next, the arrival timing of each elevator is checked and displayed on the guide display device in the hall of the car call service floor. Waiters in the hall look at the service floor displayed on each elevator and select the elevator to board according to their destination floor. Since the destination floors of passengers in each elevator are organized, the dumpling operation state is unlikely to occur.

The allocation of service floors can be fixed at all times, but can be a variable specialty depending on traffic demand, and can be changed according to the number of elevators arriving at the departure reference floor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In this embodiment, a building having a service floor on the 13th floor and three elevators installed side by side is taken as an example. An example in which the sharing guide display control according to the present invention is performed on the departure standard floor during the busy office hours of this building will be described.

FIG. 1 shows an embodiment of the system configuration of the present invention. In the figure, reference numeral 1 is a group management control device for integrally managing each unit control device in order to efficiently operate three elevators installed in this building. Reference numeral 2 is a hall call registration device installed to call an elevator installed on each floor. Cp2 in the group management control device 1 is a group management control device and each floor hall call registration device 2
And a communication control program for exchanging data with the three machine control devices 3, 4, and 5. cp1 is an operation control program that manages allocation of hall calls registered on each floor and other programs in the group management control device. c
p3 is a hall display control program that creates data to be transmitted to the hall display of each car. cp4 is a traffic demand determination program for determining the traffic demand based on the number of people getting on and off the car received from each unit control device and the information from the hall call registration device. ct1, ct2, ct
3 and ct4 are an elevator specification data table, an elevator control data table, a hall call table, and a car call table, respectively, which are used for operation control.

Each unit control device 3, 4, 5 is an actual hall display device 6, 7, 8 based on the motor control of each elevator, door control and the output of the hall display control program cp3 in the group management control device 1. Control. Also, the number of people getting on and off each floor is detected based on the output of the underfloor weighing device in the car, and is transmitted to the group management control device. The hall indicators 6, 7, 8 display instructions from the hall indicator control program cp3 in the group supervisory control device 1 via the respective unit controllers 3, 4, 5.

FIG. 2 is an embodiment of a flow chart for performing the sharing guide display control.

It is assumed that the sharing guidance display control program is managed in the operation control program. When the sharing guidance control command is issued, the sharing guidance is performed on the first floor, so in step P110, the estimated arrival time of each elevator to the first floor is calculated. For this calculation, the rated speed of the elevator and the assigned hall calls and car calls are used. Now, suppose that the situation of the elevator is as shown in FIG. In Figure 3, three elevators service the 13th floor. In FIG. 3, Δ indicates a hall call in the assigned UP direction, ● indicates a registered car call, □ indicates the floor position of each unit, and the arrow in □ indicates the operating direction of the elevator. It is assumed that the estimated arrival time of each elevator to the first floor is 12 seconds, 9 seconds, and 75 seconds, respectively. Figure 2
In step p120 of, the elevators that are likely to arrive at the first floor one after another, that is, the elevators whose estimated arrival time is near are searched. In this embodiment, elevators whose arrival predicted time difference is within 10 seconds are set as elevators that arrive in succession. As in the present invention, the estimated arrival time may be used for successive arrival determinations, or the current elevator driving direction and floor position may be used. Well, Figure 3
In the state of, the estimated arrival time of Units 1 and 2 is 12 seconds,
Within 9 seconds, the difference is 3 seconds, which is within the reference time. That is, it is determined that they will arrive one after another.

Next, at step p130, an operation plan is made for the car call service floors on and after the first floor for the first and second vehicles which are expected to arrive one after another. Details of step p130 will be described later. In step p130, the car call service floor of the first car is determined from the second floor to the seventh floor, and the car call service floor of the second car is determined from the eighth floor to the thirteenth floor. In step p140, the car call service floor determined in step p130 is displayed to the customer waiting for the elevator in the hall on the first floor.
At this time, since the car call service floor of Unit 3 is not planned, the usual date and time are displayed. A display example at this time is shown in FIG. Reference numerals 61, 71, 81 in FIG. 4 denote hole lanterns. In the group management control system that adopts the hall call reservation system, when the hall button is pressed, the elevator to be serviced is selected and decided, and the hall lantern corresponding to that car is turned on. In group management control systems other than the hall call reservation system, the hall lantern is used simply to indicate the arrival of the elevator. In this embodiment, the hall lanterns of Units 1 and 2 are lit. In the case of an elevator that adopts the normal group management control method, only one elevator responds to one hall call, but during such congestion hours, multiple elevators will be sent to the departure reference floor on the first floor. May be assigned. At this time, the hall lantern is turned on for each unit, but if there is no function to display the service floor for each unit as shown in this embodiment, it is expected that the user will be confused. next,
According to the displayed floor, passengers waiting in the hall board the elevators arriving one after another and head to the destination floor.

The car call service floor display for Units 1 and 2 is returned to the normal display because each elevator is closed after the elevator is closed and is no longer necessary (step p150). In addition,
In step p160, it is assumed that the car calls other than those on the service floor displayed on the first floor cannot be registered for the first and second cars, but in consideration of the convenience of passengers in the wrong boarding,
It may be possible to register a car call outside the service floor.

In steps p170 and p180, after servicing while calling up to the top floor where there are hall calls and car calls, in step p190, in step p160
Cancel the floor car call non-registration function other than the display floor set in.

Now, an embodiment of the operation plan of the car call service floor in step p130 will be described.
Here, a method of determining the car call service floor when the number of elevators arriving at the departure standard floor on the first floor is two will be described, but it goes without saying that the same can be done when there are three or more elevators. FIG. 5 shows a flowchart for planning the operation of the service floor.

First, at step p1301, the car call service floor operation planning subroutine is entered. Next, in step p1301, the number of people getting off at each floor during the UP direction operation for the past 5 minutes is obtained from the information from the traffic demand determination program cp4 in the group management control device, and is set to ak. However, k = 2 to 13. In step p1302, the total sum P of ak is calculated. This P represents the total number of people getting off during the last 5 minutes during UP driving. Step p1303
Then, a floor is calculated such that P obtained in step 1302 is reduced to about half, and the floor is set to n. Step p130
In step 4, from the divided floor n obtained in step P1303,
Each car call service floor of two elevators,
The floors 2 to n and the floors n + 1 to 13 are assumed.

If the car call service floor planning subroutine described above is used, the passengers in the cars of the two elevators can be made uniform based on the traffic demand based on the actual number of passengers currently getting off.

As another embodiment, paying attention to the hall calls in the UP direction, which are already assigned to the first and second units, there is also a method in which the floor with the hall call is positively set as the service floor for the car call. Here, the service floors of the two elevators are the two zones of the low-rise and the high-rise, but due to the characteristics of the traffic demand in the building, a so-called skip operation method may be adopted in which even floors or odd floors are serviced. . In this way, by distributing waiting services to the two elevators, operation efficiency is improved and serviceability of users is improved.

[0025]

As described above, according to the present invention, 1
When multiple elevators arrive on one floor one after another, elevator control including a guide display device that takes into consideration the operating efficiency after servicing that floor and the serviceability of the elevator user in that floor hall is considered. Can be realized.
