Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for assigning and operating cars to station calls.

Recently, in elevators using a group management system that manages multiple cars as a group, a Habata call is assigned to each car, and each car is serviced while responding to its own car call and the assigned Habata call. The assigned basket is
A group control elevator has been proposed that uses an assignment method in which the arrival forecast light on the floor where the assigned Hata call is located and in the same direction as the Hata call is turned on.

In a group control elevator using the above allocation method, when a car in service becomes full, the Hata field that is already assigned to this car in front of this car in the driving direction, or the Hata field that will be allocated after it becomes full. may pass through.

In order to improve this point, the following measures have been conventionally taken.

When a counter car is full, all Hataba calls will not be assigned to this car.

t) When a car is full, a Hata field call in the same direction as the car's driving direction is not assigned to this car.

[U] If the basket is expected to be full when taken to a certain Hataba, the basket will be moved from the Hatayu where this basket is currently located to the Hataba where it is expected to be full. Do not assign a field call in the same direction as the car's driving direction.

However, in the case of resistance, there are cases in which the Hata field call, which may be assigned, is not assigned.

In other words, passengers in the car will normally have gotten off the car by the time the car's driving direction is reversed, and even if it is currently full, it may no longer be full by the time the car's driving direction is reversed. . Therefore, it is inappropriate not to allocate the front call in the direction opposite to the car driving direction, such as the drag. (A) is an improvement on the drawbacks of the previous car, but in buildings where there are specific floors such as meeting room floors, it is possible that most of the passengers in the car will get off at the specific floor and the car will not be full.

In such a case, it is inappropriate not to allocate even the Hata station calls beyond the specific floor (including the specific floor) because the Hata station is in the same direction as the car driving direction. {With ヮ, it is necessary to predict that the car will be full before it becomes full, and it is difficult to accurately collect the information necessary for this prediction, making the process complicated.

The present invention is intended to improve the above-mentioned drawbacks, and aims to provide an elevator operating device which, when a car is full, takes into account a specific floor and assigns a call to the car.

Hereinafter, an embodiment in which the present invention is applied to a seven-stop elevator will be described with reference to FIGS. 1 to 4.

In Figure 1, 1 to 7 are the floors from the 1st floor to the 7th floor, respectively, (Father U) is the upstream Hataba call for the 3rd floor, (7CD) is the downbound floor call for the 7th floor, and 11 is the 1st floor call. The car 12 is ascending and descending from the 7th floor, and the diagonal line indicates that the 4th floor 4 is a specific floor.

In Fig. 2, la to 7a are car position signals indicating the car positions on the 1st to 7th floors, and lc to 6c, 7d to 2d are scanning pulses that generate pulses in this order at a constant cycle, and their waveforms are It is shown in Figure 4. 2e to 7e, lf to 6f are AND gates; 13 is a rising direction signal that becomes "1" when the car is in the rising direction; 14 is a descending direction signal; 15 is a full signal that becomes "1" when the car is full; 16 is a specific floor car call signal which becomes "1" when there is a car call on a specific floor; 17-1

is set when the input signal "1" is given to the S terminal, and the output signal becomes "1", and maintains that state even if the input signal of the S terminal becomes "0", and the input signal "1" is given to the R terminal. When is given, IJ is set, the output signal Q becomes "0", and the input signal of the R terminal is a memory that retains its state even if it becomes "OJ", 23 is an AND gate, and 23a is the output signal of AND gate 23. The waveform is shown in FIG.

24 is an OR gate.

In Figure 3, 2g to 7g are the downbound Hata field call assignment signals for the 2nd to 7th floors assigned to the car, lh to 6h, respectively.
is the same as signals 2g to 7g, and is the up-hall call assignment signal for the 1st to 6th floors of that car, 2i to 7i, l k to 6k is A
ND gate, 2m to 7m, ln to 6n are prohibited gates, 2
p~7p, lq~6q are memories similar to memory 22, 2
pa to 7pa are output signals of memories 2p to 7p, respectively;
lqa to 6qa are the output signals of memories q to 6q, respectively, and 2pa to 7pa are the output signals of the second floor to 7 to which the car should respond.
The signals 1qa to 6qa serve as the downward call signals for the floors, and lqa to 6qa serve as the upward call signals for the 1st to 6th floors.

2t to Tt, lu to 6u are the OR gates, 2v to 7v are the descending arrival forecast lights installed in the Hata area of each floor, lw to 6w are the same upstream arrival forecast lights, and 25 is the after the stop command is issued to the car. The stop signal 26 is "1" from when the car actually stops and the car door opens until the door closes halfway. "1
The pulse signals 27 and 28 are AND gates.

Note that the circuits shown in FIGS. 2 and 3 are provided for each car 11, 12.

Next, the operation of this embodiment will be explained for the case of the car 11.

Since the car 11 is moving up the first floor, the first floor car position signal la and the ascending direction signal 13 are "1".

Now, let us assume that we are going to allocate the 3rd floor upstream Hataba call length (U) and the 7th floor downhill Hataba call (7CD) to car I1.

At this time, if the car 11 is not full, or even if it is full but there is no car call for a specific floor, the "full signal 15" or the specific floor car call signal 16 becomes "0", and the AND gate 2
The output 23a of No. 3 becomes "0". Therefore, since the third floor ascending Hata field call assignment signal 3h is "1", when the scanning pulse 3c becomes "rl", the output of the prohibition gate 3n becomes "1", the memory 3q is set, and the output signal 3q
a becomes "1". And the output of OR gate 3u is also "
1'', the inbound arrival forecast light 3w on the third floor lights up, notifying that the car 11 will be serving that floor. Also, 7
Downstairs floor call assignment signal 7g is also “IJ, so
When the scanning pulse 7d becomes "1", the prohibition gate 7m
becomes "1", memory 7p is set, and output signal 7
pa becomes "1". In addition, the output of the OR gate 7t is also “
1'', the downbound arrival forecast light 7v on the 7th floor lights up, notifying that the car 11 will be serving that floor. and,
The output signals 3qa and 7pa are the mill calls to which the car 11 should respond. Furthermore, in this state, when the car I1 ascends to the third floor, the third floor car position signal 3a is output, and in order to make the car 11 respond to the output signal 3qa, an arithmetic circuit (not shown) of the car 11 is activated. A stop signal 25 is issued from.

In addition, since the pulse signal 26 becomes "1" at a constant period,
The output signal of the AND gate 28 becomes "1". Since the output signal of AND gate 3k also becomes "1", memory 3q is reset and its output signal 3qa becomes "0". At this time, the third floor upbound arrival forecast light 3w is turned on through the AND gates 28, 3k, and the OR gate 3u, so the signal is input to the AND gate 28 until the stop signal 25 becomes "0". It blinks in synchronization with the pulse signal 25. This notifies Hataba that the car 11 has arrived at the third floor. Next, if the car 11 is full and has a car call for a specific floor, the output signal of the AND gate 11 becomes ``1'' when the scanning pulse lc becomes ``1''. OR gate 18, AND gate 2
1 and the output signal of the OR gate 19 also becomes "1", which is set in the memory 22, and the output becomes "1". Since the full signal 15 and the specific floor car call signal 16 are both "1", The output 23a of the AND gate 23 becomes "1". Even if the scanning pulse lc becomes "0" in this state, the output of the memory 22 is kept at "1", so the output signal 23a
remains at "1". However, the scanning pulse 4c is "1".
”, the output signal of the OR gate 24 becomes “1”,
The memory 22 is reset and the output signal 23a becomes "0". Thereafter, even if the scanning pulse 4c becomes "0", the memory 22 remains in the reset state until the input signal at the S terminal becomes "1". That is, the output signal 23a of the AND gate 23 has the waveform shown in FIG. in this way,
When the car 11 is full and there is a car call on a specific floor, the scan pulse 3c will be "1" for the 3rd floor upstream Hataba call even if the 3rd floor upstream Hataba call assignment signal 3h is "1". Since the signal 23a is "1", the prohibition gate 3n
The output of the memory 3q becomes "0", the memory 3q maintains the reset state, and the output signal 3qa remains "0", so no allocation is performed.

However, regarding the 7th floor, if the 7th floor descending station call assignment signal 7g is "1", when the scanning pulse 7d becomes "1", the signal 23a is "0", so the prohibition gate 7
The output of m becomes "1", the memory 7p is set, and its output signal 7pa becomes "1", so the downbound arrival forecast light 7v of the seventh floor is lit and the car 11 is assigned to that floor. In this way, allocation will be prohibited to the Hata yard in the same direction as the car driving direction from the car to the first floor of the specific floor, but allocation will not be prohibited to other Hata yard. .

In addition, in the above embodiment, a case was explained in which the relevant Hataba call is not newly assigned to a car that is full; The allocation may be canceled.

Further, the specific floor may be any floor, or there may be a plurality of floors.

Further, specific floors may be changed or omitted depending on traffic conditions, car conditions, time of day, etc. For example, if a specific floor is changed depending on the direction of the car, and the car is ascending, it is expected that the specific floor for the ascending car will become full, and if the car is descending, the When it is expected that a specific floor for an inner car will be no longer full, the relevant Hataba call is not assigned to each car. In addition, traffic conditions, car conditions, time,
The implementation means may be changed depending on the specific floor to be targeted.

For example, in the case of a building with 7 stops as in the above example, the 4th and 7th floors are designated as specific floors for a car that is ascending, and the 4th floor is targeted only when there is a call for a car on the 4th floor. Regarding the 7th floor, it does not matter whether there is a car call or not. When the car is full on the floors above the 4th floor (including the 4th floor), the 7th
Set the floor as a specific floor and do not assign the corresponding landing call to the car.
When a car is full on a floor below the 3rd floor (including the 3rd floor), if there is a car call to the 4th floor, the 4th floor will be designated as a specific floor, and if there is no car call to the 4th floor, the car will be set to 7. The floor is set as a specific floor, and the relevant Hataba call is not assigned to the car.
In this case, for cars that are full on floors below the third floor,
If it is not appropriate to allocate the Hataba call up to the 7th floor, the 7th floor may be set as a specific floor only for cars that are full on floors above the 4th floor. Regarding the allocation of Hataba calls when the car is full,
Although various proposals have been made in addition to this invention, they may be used in combination with this invention, and furthermore, these may be changed depending on traffic conditions and the like.

For example, when a car that is descending is full, the present invention does not allocate the relevant Hata call, and when a car that is ascending is full, the car is moved from the floor where the car is located to the first call. To avoid assigning a front call in the same direction as the car driving direction up to the first floor before the floor where the car call is located. As explained above, in this invention, when a car is full and the car has a car call for a specific floor, it is possible to Since we have decided not to assign a Hataba call in the same direction as the driving direction of the car, we can detect that a passenger is getting off the car at a specific floor, and then allocate a Naba call after the car has stopped at a specific floor and the car is no longer full. It is possible to provide an efficient elevator service that can quickly respond to requests.
