Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for operating and managing a plurality of cars as a group.

In the elevator group control device, operation is managed so as to respond to car calls registered within each car and hall calls common to each car registered at each floor landing.

Now, as shown in FIG. 1A, it is assumed that the car a of car A is running down the 9th floor, and the heel b of car B is running up the 3rd floor.

In addition, on the 8th, 7th, and 3rd floors, there are 8a
, 7a, and 3a are registered, and it is assumed that a long time has passed since the down calls 8a and 3a for the 8th and 3rd floors were registered.

Car a stops on the 8th floor in response to the down call 8a, picks up passengers on the 8th floor, stops on the 7th floor, picks up passengers again, and then heads downward.

In this way, if there is a landing call in the same direction as car A, it will stop at that floor, so passengers from the 8th floor who have been waiting for a long time will be delayed in arriving at their destination floor. ,
For this reason, passengers from the 8th floor are forced to wait for a long time at the landing and even longer in car a, which makes them feel even more anxious.

This invention is intended to improve the above-mentioned problem, and when a car responds to a hall call that has been registered for a long time, the number of hall calls to which it should respond is limited, and passengers who have been waiting for a long time at the hall are To provide a group control device for elevators that allows elevators to arrive at a destination floor quickly and relieves a sense of impatience.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In Figure 2, 2aa to 9aa are registered at the landings on the 2nd to 9th floors, respectively, and become "1".When a down-hall call is registered and is not answered even after a specified period of time has elapsed (such calls are A long-term waiting call (also called a long-term waiting call) is a long-term waiting call signal that goes to "1", and the details are explained in FIG.

2c to 9c are OR gates, 2d to 9d are AND gates,
2e to 9e are OR gates, 2f to 9f are AND gates,
2fa to 9fa are the outputs of AND gates 2f to 9f, respectively, and a response down call signal 11 that causes car a to respond to a down call from the 2nd to 9th floors is a response signal 11 when the driving direction of car a is in the down direction.
The down direction signal becomes "1", 12 is the response signal that becomes "1" when car a responds to a long-term waiting call, and 13 becomes "1" when it completes responding to the hall call and car call and is waiting. The standby car signal 14 is an inverter gate.

In Fig. 3, 2g to 9g are car position signals that become "1" when car a reaches the position where it can properly decelerate and land on the 2nd to 9th floors, 2h to 9h are AND gates, 21 to 91 and 10i is an inverter gate, 2j to 9j have an input of "1"
A timer device whose output becomes "1" after a specified period of time (for example, 30 seconds) has passed, 2k to 9k are AND gates,
15 is a stop decision signal which becomes "1" when car a decides to stop; 16 is an OR gate; and 17 is a storage device.

Next, the operation of this embodiment will be explained.

Now, the positions of cars a and b, driving direction and hall call position,
Assuming that the directions are as shown in Figure 1, the down call signals 8aa, 7aa, and 3aa for the 8th, 7th, and 3rd floors are "1".
It has become.

Further, since the down calls on the 8th floor and the 3rd floor are long waiting calls, the long waiting signals 8b and 3b are set to "1".

Since car a has not yet responded to the long-term waiting call,
The response signal 12 is "0".

Therefore, the output of inverter gate 4 becomes "1",
The outputs of the OR gates 20-9c also become "1" and the AND gates 2d-9d are opened.

At this time, since the car a is running in the down direction, the down direction signal 11 is "1", so the AND gate 2d
The output of -9d becomes "1", the output of OR gates 2e-9e also becomes "1", and AND gates 2f-9f are opened and the hall call can be read.

As a result, the outputs of the AND gates 8f, 7f, 3f, that is, the response down call signals 8fa, 7 for the 8th, 7th, and 3rd floors.
fa and 3fa become "1".

As a result, car a stops at the 8th floor in order to respond to the down call 8a from the 8th floor.

On the other hand, the down call signals 8aa and 3aa on the 8th and 3rd floors are "1".
'', the output of the timer 8j, 3j, that is, the long-term waiting call signal 8b.
, 3b are "1".

When the car a stops at the 8th floor, the car position signal 8g, the down direction signal 11, and the stop decision signal 15 all become "1".

Therefore, the output of AND gate 8h becomes "1", and A
The output of the ND gate 8k also becomes "1".

Also, the output of the OR gate 16 becomes "1" and the storage device 1
7 is set and the response signal 12 becomes "1".

As a result, car a becomes the car that has responded to the long-term waiting call.

When car a stops on the 8th floor, the down call signal 8aa is "0"
Therefore, the output of the inverter 81 becomes "1" and the timer 8j is reset.

When car A is driven down from the 8th floor, the hall call is read again, but at this time, in FIG. 2, since the response signal 12 is "1", the output of the inverter gate 14 becomes "0". .

In addition, since the down call 7a on the 7th floor is not a long-term waiting call, the timer 7j does not output an output and the signal 7b is "0".
”.

Therefore, the output of the OR gate 7c becomes "0" and the AND
Since the gate 7f is closed and the down call signal 7aa on the 7th floor cannot be read, the signal 7fa becomes "0".
Car a passes through the 7th floor.

Since the signal 3b is "1", the OR gate 3c, AND
The outputs of gate 3d and OR gate 3e become "1", and A
ND gate 3f is opened.

Therefore, the down call signal 3aa for the third floor is read, and the 3rd floor down call signal 3aa is read.
The floor response down call signal 3fa becomes "1", and the car a stops at the third floor.

As with the 8th floor, the timer 3j is reset.

In this way, once a car has responded to a long-term waiting call, it will only respond to car calls (the car call stop circuit is omitted) and other long-term waiting calls, and will not respond to other hall calls. .

This reduces the number of times the car stops, and allows customers who have been waiting for a long time to reach their destination floor more quickly, alleviating the frustration of those customers.

4 to 7 show other embodiments of the invention.

In Figure 4, 1g is the 1st floor car position signal of car a, 1l to 9
l is a time pulse that becomes "1" by sequentially shifting the time as shown in Fig. 6, 1m to 9m are AND gates, and 20 is an OR gate.
gate, 21 is AND gate, 21a is AND gate 2
This is the output of 1.

In Fig. 5, 1n is the time pulse shown in Fig. 6, and 21X is a
A signal that becomes "1" when any of the signals 21a of a machine other than machine No. 2 (in this case, car B) also becomes "1", 2
2 is an OR gate, 23, 24 is an AND gate, 25
2 is an inverter gate, 26 to 28 are storage devices, and the output 121 of the storage device 28 is used as the response signal 12 in FIG.

131 is "1" when machine a or machine b is on standby.
The standby car detection signal and the others are the same as those in FIGS. 2 and 3.

Now, as shown in FIG. 1B, it is assumed that there is a succeeding car B above car A that is running in the same direction as car A.

As explained in FIG. 3, when the car a stops on the 8th floor where there is a long-term waiting call, the response signal 12 becomes "1".

In Figure 4, car a is on the 8th floor, so the car position signal 8g is
1”, and when the time pulse 8l becomes “1”, AN
The output of the D gate 8m becomes "1", and the output of the OR gate 20 becomes "1".

Since the down direction signal 11 of car a is "1", AND
The output 21a of the gate 21 becomes "1", and the memory device 26 in FIG. 5 is set.

Further, the output of the AND gate 23 becomes "1", and the memory device 27 is also set.

Since car B is on the 9th floor and is operating in the down direction, similarly when time pulse 9l becomes "1", the AN of car B
The output 21a of the D gate 21 becomes "1".

That is, the signal 21X becomes "1", resets the storage device 26, and its reset output becomes "1".

When the time pulse 1n becomes "1", all the inputs of the AND gate 24 become "1", so its output becomes "1", the memory device 28 is set, and its output 121 becomes "1".
become.

(Figure 7) This output 121 causes the inverter 1 in Figure 2 to
Since the output of No. 4 becomes "0", as described above, car a does not stop at the 7th floor, but only at the 3rd floor where there is a long waiting call.

When there is no subsequent car (in this case, car B is replaced by car A)
), the signal 21X is ``0'' and the memory 26 is not reset, so the AND gate 24 is not opened.3Therefore, the memory 28 is not set and the output 121 is ``0''. ”.

Therefore, car a will stop at the 7th and 3rd floors.

Note that even if there is no subsequent car, if there is a waiting car, the waiting car detection signal 131 becomes "1", and the same operation as when there is a subsequent car occurs.

Further, when the car a finishes its downward direction operation and starts its upward direction operation, the signal 11 becomes "0", the output of the inverter gate 25 becomes "1", and the storage devices 27 and 28 are reset.

In this way, a car that responds to a long-waiting call will be restricted from reading the hall call only when there is a car following the car, and will only respond to long-waiting calls such as car calls and other long-waiting calls. They will no longer respond to boarding calls.

As a result, a passing hall call will be answered by a subsequent car, and the possibility that the hall call will be kept waiting for an unreasonably long time is reduced.

Assuming that car b in Figure 1B also responds to a long-term waiting call and has a following car, then the down-call 7 on the 7th floor
There is a possibility that a will not be responded to for more than a specified time because it will not be responded to by either car a or b and will be passed through.

In order to avoid this, when the output 121 of car b becomes ``1'', the output 21a of car b becomes ``0'', so that the signal 21X becomes ``0''. Basket b
The basket cannot be a successor to basket a.

Therefore, the car a will respond to the down call 7a on the seventh floor.

8 to 10 also show other embodiments of the invention.

Assume that car a and the succeeding car b are far apart as shown in FIG. 1C.

Since car a has a succeeding car b, the long waiting call 5a
If you answer the call, you will receive a call 4 from the 4th floor, which is not a long-waiting call.
a will pass.

Car b will respond to the down call 4a on the fourth floor, but since it is far away, it will take time to respond.

Therefore, there is a possibility that the down call 4a on the fourth floor will be made to wait longer than the specified time.

Fig. 8 shows an improvement on this. In Figure 6, 1p to n
p is a time pulse that is emitted following time pulse 9l at the same time interval as time pulses 1l to 9l; 30 in FIG. 8 corresponds to the OR signal of time pulses 1l to 9l and 1p to np. Time pulse (Fig. 9), 31 is a counter that counts the number of pulses of time pulse 30, and when this reaches a specified number (for example, when 3 pulses are counted), the output becomes "1"; 32 is a storage device; 33 and 34 are AND gates, and 35 is an inverter gate.

Note that the output 122 of the storage device 28 is the response signal 1 in FIG.
Used as 2.

Others share FIGS. 2 to 4 and FIG. 6.

Since the car a has responded to the long-term waiting call 5a, the response signal 12 in FIG. 3 becomes "1".

Since car a is on the 5th floor and is running in the downward direction, when the time pulse 5l becomes "1", the output of the OR gate 20 becomes "1", and the output 21a of the AND gate 21 becomes "1".
” and the storage device 26 is set.

The storage device 27 is also set.

By setting the memory device 26, its reset output becomes “0”.
”, and the counter 31 starts counting the time pulses 30.

On the other hand, assuming that car B is on the 7th floor (car bt) and is operating in the downward direction, the time pulse 7l is "1".
When , the output 21a of the AND gate 21 of machine b
becomes "1".

That is, the signal 21X becomes "1", the storage device 26 is reset, its reset output becomes "1", and the counter 31 is also reset.

At this time, only two pulses 5l and 6l are input to the counter 31, so the output of the counter 31 does not become "1" and the memory device 32 is not set.

Therefore, the reset signal of the memory device 32, which was reset by the time pulse 2n, has become "1", and the AND gate 33 is opened.

Therefore, when the time pulse 1n becomes "1", the memory device 28 is set and the output 122 becomes "1".

(Figure 9) Because of this output 122, the output of the inverter 14 in Figure 2 becomes "0", so the car 9 does not stop at the 4th floor, but only at the floor where there is a long waiting call. .

If car B is on the 9th floor, time pulse 9l is "1".
When this happens, the output 21a of the AND gate 21 of machine b becomes "1".

That is, the signal 21X becomes "1", the storage device 26 is set, and its reset output becomes "1".

However, at this time, since three or more pulses 5l to 8l are input to the counter 31, the output becomes "1" before being reset, and the storage device 32 is set.

Therefore, the reset output becomes "0" and the AND gate 33 is closed.

Therefore, the storage device 28 is not set and the output 122
remains "0".

As a result, car a also comes to stop on the fourth floor.

In this way, a car that has answered a long-waiting call will answer only that car call and other long-waiting calls when the following car is nearby, but will only answer other long-waiting calls when the following car is far away. This reduces the possibility that the passenger will have to wait an unreasonably long time for that hall call.

Although succeeding car b has been described as a car operating in the same direction as car a, it can also be a succeeding car even if it is operating in the opposite direction.

That is, when car b in FIG. 1C is operating in the upward direction, if car b goes up to the 9th floor, it will then operate in the downward direction, so it can be considered as a subsequent car to car a.

In order to make car b the succeeding car, it can be easily implemented in terms of the circuit by increasing the time pulses shown in FIG.

In addition, although the above-mentioned each Example demonstrated the down direction driving|operation, it is clear that the upward direction driving|operation can also be easily explained.

As explained above, in this invention, the first car that has responded to a hall call for which a predetermined time has elapsed since registration is made to respond only to the car call and other hall calls for which a predetermined time has elapsed. This allows passengers who have been waiting for a long time at the landing to arrive at their destination floor quickly, alleviating their frustration.

In addition, since the above operation is performed when there is a second car following the first car and it is within a specified distance from the first car, even if the hall call is not a long waiting call, the following car It is possible to reduce the possibility of having to wait an unreasonably long time due to the presence or location of the person.
