Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for a group control elevator,
The present invention particularly relates to a control device suitable for enhancing services on specific floors where traffic demand is high.

In buildings equipped with group control elevators, traffic demand on each floor is not uniform and varies considerably depending on the purpose of the floor. In particular, connecting floors where a building connects to ground transportation always have a higher traffic demand than other floors, and there are many cases where inexperienced visitors wait for elevators to arrive without registering for a hall call. Additionally, the number of passengers on the dining floor temporarily increases during lunch time.

In order to handle traffic demand on a particular floor that is congested in this way, conventional group management control has adopted the following control method.

(1) The above communication floor is set as the departure standard floor for group management control, and any number of elevators is always returned to the departure standard floor after the service is completed.

(2) In the case of a driving mode that passes through the standard departure floor (driving mode from a floor below the standard departure floor to a floor above the standard departure floor), the passenger waiting on the standard departure floor should be stopped by the standard departure floor once. Let them board.

By the way, this type of control method has the disadvantage that if a passenger boards the elevator at a floor below the standard departure floor, the elevator will always make a stop at the standard departure floor, resulting in a delay in arriving at the preceding floor. There are drawbacks.

An object of the present invention is to provide a control system for group-controlled elevators that eliminates the drawbacks of the prior art as described above, strengthens services on specific floors with high traffic demand, and prevents unnecessary forced stops of elevators. It's about doing.

A feature of the present invention is that an elevator heading from either the upper floor or the lower floor of a specific floor with high traffic demand to the other floor is connected to the specific floor by another service elevator in the same direction as the elevator. The point is that the vehicle is decelerated and stopped only when there is no call to stop at the specific floor.

The embodiment of the present invention shown in FIG. 2 and the first embodiment shown in FIG.
This will be explained in detail using figures.

First, the operating principle according to the present invention will be explained using FIG. 1. FIG. 1 is an explanatory diagram of the operation of the present invention. In FIG. 1a, car A (hereinafter referred to as car A) is waiting for departure for an upward service at the departure standard floor S, and car B ,D
Cars B and D (hereinafter referred to as Cars B and D) are traveling above the departure standard floor S, and car C (hereinafter referred to as Car C) is on the destination floor F above the departure floor where passengers from below the standard departure floor S boarded. It is in a state of rising towards.

In such a state, passengers waiting on the departure standard floor S can use the A car, and the C car ascending from below does not need to decelerate and stop at the departure standard floor S.

Figure 2b shows a situation where there is no aircraft on the departure standard floor S to provide ascending service.In this case, the C aircraft ascending from below decelerates to a stop at the departure standard floor S and stops once to meet the departure standard. The service on the floor can be enhanced.

Therefore, in the present invention, in the case of the example shown in Fig. 1a, the C car is not decelerated and stopped at the departure standard floor,
Only in the case of the example shown in FIG. 2b, the control was made to decelerate and stop Car C at the departure standard floor. Although FIG. 1 has been described as a departure standard floor, the same applies to specific floors where traffic demand is higher than general floors.

FIG. 2 is a circuit diagram showing one embodiment of the present invention. In Figure 2, f _B - f ₄ are the floor levels of floors B - 4, BD - 3D are fixed contact pieces for descending deceleration on floors B - 3, and 1U - 4U are fixed contacts for ascending deceleration on floors 1 - 4. On the other hand, FD is the movable contact for descending deceleration, FU is the movable contact for ascending deceleration, 10 is the normally open contact of the operation relay,
11 is a normally open contact of an upward operation relay, 12 is a normally open contact of a downward operation relay, D is a diode, 70 is a normally open contact of a relay that is turned on when there is no upward serviceable elevator on the departure standard floor (specific floor), 1
C to 3C are the normally open contacts of the car call relays on the 1st to 3rd floors,
PA _a is a relay that turns on when traffic demand is particularly high.
PB a is a normally open contact of PA, PB _a is a normally open contact of a driving pattern relay PB set according to traffic demand, 90 is a deceleration relay, and P and N are power supplies, which are connected as shown.

Now, when ascending from the basement floor f _B by a car call on the third floor above ground, the movable contact FU for deceleration of ascending is set to 1.
When it comes into contact with the fixed contact piece 1U for deceleration ascent to the first floor, which is planted before the deceleration distance necessary to decelerate and stop on the floor, the traffic demand is particularly high, and relay PA is turned on, causing its contact PA _a to close. P
-10-90-11-FU-1U-PA _a -N turns on the deceleration relay 90, and its contact _90a closes to maintain self-retention, and the car decelerates to a stop on the first floor.

Also, by turning on the operation pattern relay PB,
If its contact PB _a is closed, contact 70
P is closed only when P
-10-90-11-FU-1U-70-PB _a -
The deceleration relay 90 is turned on by the N circuit, and the car decelerates to a stop on the first floor. Note that the circuit shown in FIG. 2 is provided for each elevator.

As a result of the above, when the departure standard floor is extremely congested with high traffic demand, contact PA _b closes, and all elevators passing through the departure standard floor will decelerate and stop temporarily even if there is no car call registration. In this case, the elevator decelerates to a stop and enhances service only when contact 70 and PB _a are closed, that is, when contact PB _a is closed and there is no elevator capable of upward service on the departure standard floor. . Therefore, when service enhancement is not required, the elevator ascending from below is not forced to stop, and the conventional drawbacks are improved.

The embodiment shown in Fig. 2 is shown using the departure standard floor as an example, but some circuit changes may also be made for specific floors where service needs to be strengthened at specific times, such as food floors. The present invention can be implemented by using the same method, and similar effects can be obtained.

As explained above, according to the present invention, it is possible to strengthen the service on a specific floor where traffic demand is high, and to prevent unnecessary forced stops of elevators.
