Abstract

PURPOSE:To speedily transport users when a number of users are concentrated to a specific floor in a leisurely time. CONSTITUTION:A switch 4SWD is installed at the front of a hotel. When the switch 4WSD is operated, and users are concentrated to a specific floor, e.g. fourth floor, and a descent call button at this specific floor is operated, a relay 4ABD is energized, and contact points 4ABDa1 and 4ABDa2 are closed, and relays 4DA and 4DB are energized, and the call for the A machine and B machine is registered.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a back control device for a group-controlled elevator, and more particularly to registration of calls when users are concentrated on a specific floor during a quiet period.

[0002]

2. Description of the Related Art A group-controlled elevator is controlled so that a waiting time is short with respect to traffic demand and power consumption is small. Therefore, under low traffic demand,
For example, as disclosed in Japanese Examined Patent Publication No. 54-8932, the service range of the elevator is divided into a plurality of zones and the elevators are placed in standby in each zone, and each elevator responds to a hall call within its own service zone. Only controlled to respond.

[0003]

The above-mentioned conventional device is a very effective means when a hall call is sporadically generated on all floors. By the way, elevators for hotels generally have many customers in the morning and evening, but are quiet during the daytime. On the other hand, occasional events such as daytime weddings and lectures are held on specific floors, and many passengers use the elevator at the same time before and after the start of the event, but at this time it is a quiet time. When the hall call button on this particular floor is operated, the elevators in this service zone immediately respond, but the other elevators do not respond because they are outside the service zone. Therefore, even though there are many passengers on the specific floor, only one elevator operates, which makes the passengers wait a long time, which is a problem.

The present invention has been made in view of the above-mentioned drawbacks, and an object thereof is to quickly transport a large number of passengers to a specific floor at a time during a quiet period to enhance the transportation capacity. An object of the present invention is to provide a control device for a group-controlled elevator that can do the same.

[0005]

[Means for Solving the Problems] The purpose is to register a hall call or a car call so that a plurality of cars serve a plurality of floors in a group control elevator control device, and a switch is installed at a predetermined place of a building. This is achieved by providing means for registering the plurality of cars with the hall call when the switch is provided and the hall call for the specific floor is operated.

[0006]

According to the present invention, for example, in a hotel, an event to be held on a specific floor has the date, start time and end time at the front desk. Therefore, for example, the manager turns on the switch for the specific floor at the end time of the holding date. When the event ends and the user operates the descending button on the specific floor, for example, all elevators are called to the specific floor, so that the service of the customer can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be explained. The elevators are Units A and B, and service the 1st to 8th floors. Also, during quiet times, the A units are distributed and waiting on the 1st floor, the 1st to 4th floors are serviced, and the B units are distributed on the 8th floor. It stands by and services the 5th to 8th floors, and the 4th floor is the specific floor.

FIG. 2 is a front view of the hall on the 4th floor. A is Unit A, B is Unit B, DOA is Unit A's hall door, DOB is Unit B's hall door, and hall DOA , DOB
A landing call button 4TU for ascending and a landing call button 4TD for descending are provided between the two. Since the other floors are the same, the description is omitted.

1 and 3 are electrical connection diagrams of an embodiment according to the present invention. Here, the meaning of the symbols will be described. In the relays and contacts shown in the figure, the first number is the floor, the last letter is the number, A is the number A, and B is the number B. Therefore, the machine A will be described below.

1 and 3, P and N are DC power supply terminals, 2TDa to 8TDa are contacts of descending hall call buttons on the second to eighth floors, and 2ABD is a car when the descending hall call button 2TD is operated. In the circuit for allocating A, contact 2DTa is closed when Unit A is allocated and contact 2 is allocated when Unit B is allocated.
DTBa is closed, and similarly, 4ABD to 8ABD are car allocation circuits, and any of the contacts 4DTAa, 4DTBa, contacts 8DTAa, 8DTBa are closed, respectively. 2DA
8DA is a relay that is energized when the down hall call of the second floor to the eighth floor of the Unit A is registered, 2DAa to 8DAa are its normally open contacts, and 2DPAb to 8DPAb are the second floor to the eighth floor of the car of the Unit A. A normally-closed contact of a relay (not shown) that is activated when the vehicle arrives at 4SWD is a switch provided at the front of the hotel, and 4ABD is a relay that is activated when this switch 4SWD and the landing call button 4TD on the fourth floor are operated. so,
The contacts 4ABDa ₁ and 4ABDa ₂ are normally open contacts, and the contact 4ABDa ₁ is connected in parallel with the contact 4DTAa and the contact 4ABDa is connected in parallel with the contact 4DTBa.

Next, the operation of the present invention will be described.

[0012] Now, it is assumed that the car No. A is waiting on the first floor and the car No. B is standing by on the eighth floor in a quiet time. One user operates the descending hall button 4TD on the fourth floor. Contact point 4 TDa
Is closed and the car allocating circuit 4ABD determines that it is a quiet time, and the contact 4ABDa ₁ is closed and P-4ABDa ₁
-4DPAb-4DA-N circuit activates the relay 4DA and self-holds it by the contact 4DA, and the controller A (not shown) departs Unit A from the first floor and stops on the fourth floor, and the contact 4DPAb opens and the relay 4DA. Turn off.
And service the users on the 4th floor.

Next, an event is held on the 4th floor,
For example, the end time is 12:00. At 12:00, the front management operates the switch 4SWD. At this time, since the entertainment is over and many users on the fourth floor descend to the first floor, the down call button 4TD on the fourth floor is operated. P-4TDa
-4SWD-4ABD-N circuit for relay 4ABD
Is energized, contact 4ABDa ₁ is closed, relay 4DA is energized and unit A responds, contact 4ABDa ₂ is closed, relay 4DB is energized, unit B responds, and at the same time both unit A and unit 4 You can depart for the floor, stop, and transport passengers with two cars.

As described above, when the switch 4SWD is operated and the hall call button at the time of descending the fourth floor is operated, the two elevators simultaneously respond, so that the transportation capacity can be enhanced.

In the above embodiment, the landing call at the time of descending was used as a method of registering the calls of the two cars A and B, but instead of this, a landing call at the time of ascent or a car call is used. You can also do it. Further, in the embodiment, the case of descending the fourth floor has been described, but it goes without saying that the present invention can be applied to any floor. Further, in the above embodiment, the group management of two elevators has been described, but it can be easily implemented with three or more elevators.

[0016]

As described above, according to the present invention, a switch is provided on a predetermined floor of a building, and the switch is operated,
In addition, when a hall call on a specific floor is operated, multiple car calls are registered, so even if a large number of users concentrate on a specific floor, it can be transported quickly and transport efficiency is improved. be able to.
