Description

[Detailed description of the invention] <Industrial application field> The present invention relates to an elevator group management device.

<Prior art> For example, Japanese Patent Application Laid-open No. 61-203669 and Japanese Utility Model Application No. 5
As disclosed in Publication No. 4-165462, when group control operation of elevators is performed, the cars are set at the standard li! during quiet periods. ! A first-class elevator that waits on the first floor (usually the first floor) and a second-class elevator that waits on a drop-off floor during off-peak hours are operated efficiently between multiple floors.

For the sake of simplicity, we will explain the case of group control operation of an elevator with two cars installed side by side. As shown in Fig. 2, if A is a first-class elevator and B is a second-class elevator, then Elevator A is assigned to the up calls 2U and 3U, and elevator B is assigned to the down calls 2D and 3D of the hall, and service operations are always performed in a ring shape using these elevators.

Then, during off-peak hours, when elevator A is no longer called, after a predetermined period of time, for example, one minute, elevator A travels to the standard floor and waits at the standard floor, and then when elevator B is no longer called, elevator B is no longer called. The system will be on standby on the next floor, ready to immediately respond to new calls.

<Problem to be solved by the invention> In the conventional group management method described above, for example, when a concert is held in a building where elevators are installed, a large number of elevator users gather on the standard floor as the concert time approaches. In this case, the cars waiting on the standard floor cannot handle all the passengers, resulting in unloaded cars, making it impossible to provide sufficient elevator service.

The present invention was made in view of the current status of elevator group management systems as described above, and its purpose is to provide efficient operation service to elevator users when elevator users are concentrated on a standard floor. An object of the present invention is to provide an elevator group management device that can perform the following operations.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a first type elevator in which a car waits at a standard floor during off-peak hours, and a second type elevator in which a car waits at a drop-off floor during off-peak hours. In an elevator group control system for efficiently operating a plurality of elevators across multiple floors, each car is provided with a load detection device for detecting the load of passengers in the car, The structure includes a calling means for calling the car of the first type elevator to the reference floor when the detected value of the load detecting device of the car located on the floor exceeds a predetermined detected value set in advance. ing.

<Function> In the present invention, when a large number of passengers gather on the standard floor and a large number of passengers board the cars waiting on the standard floor, the detected value of the load detection device becomes a predetermined detected value set in advance. (for example, 80% of the maximum allowable value), the calling means is activated,
The second-class elevator car waiting at the drop-off floor is called to the standard floor.

In this way, the service for passengers is efficiently provided to the cars that were already waiting on the standard floor and the cars of the second type elevators that have been called to the standard floor.

<Example> Embodiments of the present invention will be described below with reference to FIG.

Here, FIG. 1 is a circuit diagram showing the configuration of an embodiment.

For example, the first type elevator A (hereinafter referred to as A-type elevator)
A case will be described in which group management operation of elevators is performed using two elevators: 1 and 2nd class elevator B (hereinafter referred to as No. B).

A normally open contact 63Aa, a normally closed contact 63Bb, a normally closed contact Ab, and a relay B are connected in series between the DC power supply terminals PN. Similarly, a normally open contact 63Ba, a normally closed contact 63Ab, a normally closed contact Bb, and a relay A are connected in series between DC power supply terminals P and N.

Here, contacts 63A, a, and 63Ab are energized when a call for machine A is registered. Contacts of a relay 63A, not shown, and contacts 63Ba and 63Bb are energized when a call for machine B is registered. This is a contact point of a relay 63B (not shown). In addition, relay A is an auxiliary relay to call back machine A to the standard -5 = floor, relay B is an auxiliary relay to call machine B back to the standard floor, and contacts Ab and Bb indicate whether machine B or machine A is on the standard floor, respectively. This is a contact point for deenergizing relay B or relay A when the current is reached.

Normally open contact Aa and timer AT are connected between DC power supply terminals P and N.
are connected in series, and similarly, a normally open contact Ba and a timer BT are connected in series between DC power supply terminals P and N. In addition, between the DC power terminals P and N, the car call button IA in the A car car, the normally closed contact 91Ab, and the reference floor (1
The call relays 51A for each floor are connected in series with each other.

A contact 51Aa and a contact ATa are connected in parallel to each other between the connection point of the DC power supply terminal P, the car call button IA, and the contact 91Ab, and a series connection circuit of the contact 91Ba and the contact WBa is connected in parallel to the contact ATa. It is connected.

Here, contacts Aa and Ba are contacts that operate timers A, T, or timer BT when auxiliary relay A or auxiliary relay B is energized, and timers A6-T and timer BT operate for one minute. The timer, the contact IAb, and the contact 91Ba, which are set, are the relays 91A and 91B (not shown) that are energized when the A or B car is located on the reference floor (first floor), respectively. It is a point of contact.

In addition, the contact 51Aa is the reference relay 5 for the standard (first floor) of the A car, the contact ATa is the contact of the timer AT, and the contact WBa is the predetermined detection value of the load in the car of the B car. (For example, 80% of the maximum allowable value) is a contact point of a relay WB (not shown) that is energized.

A car call button IB in the car of car B, a normally closed contact 91Bb, and a call relay 51B of the reference floor (first floor) of car B are connected in series between the DC power terminals PN. In addition, the DC power supply terminal P is connected to the call button IB and the contact 91Bb.
In between, contact 51Ba and contact BTa are connected in parallel with each other, and contact 91Aa and contact WAa are connected in parallel to contact BTa.
series connected circuits are connected.

Here, the contact 91Bb is a contact of a relay 91B (not shown) that is energized when the B machine is located on the reference floor (first floor).
The contact 51Ba is the contact of the call relay 51B of the above-mentioned car No. B (1st floor with standard), the contact BTa is the contact of the timer BT, and the contact 91Aa is energized when the No. A car is located on the standard floor (1st floor). Contact point of relay 91A (not shown), contact point WA'
a is a relay W (not shown) that is energized when the load in the car of car A reaches a predetermined detected value (for example, 80% of the maximum allowable value)
This is the contact point of A.

Next, the operation of the embodiment will be explained.

When elevator operation is slow, whether machine B is in operation or machine A is in operation, if there is no call on the middle floor, relay 63 is activated.
A is deenergized and contact 63Ab is turned on. At this time, relay 63B is energized, so contact 63Ba is ON, and relay B is deenergized, so contact Bb is ON.

Therefore, DC power supply terminal P, contact 63Ba, contact 63Ab
, contact Bb, relay A, and DC power supply terminal N form a closed circuit, and relay A is energized.

When relay A is energized, contact Aa turns ON, so
A closed circuit is formed by the DC power supply terminal P, the contact Aa, the timer AT, and the DC power supply terminal N, and the timer AT starts counting. When one minute has elapsed, timer AT is activated and contact ATa is turned ON.

At this time, since Unit A is not located on the standard floor, relay 9
]-A is deenergized and contact 91. A b is ON, a closed circuit is formed by the DC power terminal P, the contact ATa, the contact 91Ab, the relay 51A, and the DC power terminal N, and the relay 51A is energized.

In this way, in order for the relay 51A to listen, the A car travels toward the reference floor (first floor), stops at the reference floor, and enters a standby state.

Next, when there are no more calls for car B, car B is abandoned at the floor where there are no more calls and becomes in a standby state.

For example, if a concert is held in a building where elevators are installed, and a large number of elevator users gather on the standard floor near the opening time, and when they get into the A car waiting on the standard floor, an unillustrated load is detected. When the device is activated and the detected value reaches 80% of the maximum allowable value, relay WA is energized and contact WA is activated.
a becomes ON.

At this time, Unit A is located on the standard floor (1st floor), so
Relay 91A is energized and contact 9]Aa is ON, Unit B is not located on the standard floor (1st floor), relay 91B is deenergized and contact 91Bb is ON. There is. Therefore, a closed circuit is formed by the DC power supply terminal P, contact 91Aa, contact WAa, contact 91Bb, call relay 51B, and DC power supply terminal N, the call relay 51B is energized, the B machine is called, and the A machine is the standard. Before starting traveling from the floor, the B car starts traveling toward the reference floor. In this way, according to the embodiment, when passengers concentrate on the standard floor, they are immediately called to the standard floor from car B or the drop-off floor, so the waiting time for passengers left behind on the standard floor is shortened. Operational services for passengers will be improved.

In addition, in the example, a case has been described in which the A-car is a first-class elevator that waits on the standard floor during off-peak hours, and the case where the B-car is a second-class elevator that waits on a drop-off floor during off-peak hours; however, the present invention is limited to the example. Instead, the A car can be used as a second type elevator and the B car can be used as a first type elevator. Further, in the embodiment, a case has been described in which two elevators are used, but in general, a plurality of elevators can be used.

<Effects of the Invention> As explained in detail above, according to the present invention, the number of passengers is concentrated on the standard floor, and if only the elevators are waiting on the standard floor,
When it is determined that there will be a backlog of passengers, the elevator waiting at the drop-off floor is immediately called to the standard floor, greatly reducing the waiting time for the passengers.
