DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device, and more particularly, to each landing display such as an arrival indicator (hole lantern, chime) or a direction indicator (direction light) provided at an elevator landing. The present invention relates to an elevator control device for controlling the operation of the elevator.

[0002]

2. Description of the Related Art Heretofore, the arrival of an elevator car has been notified to a waiting person at an elevator hall by an arrival display.
As described in Japanese Patent Publication No. Sho 63-17746, a hall lantern and an arrival chime are usually provided at the landing of each elevator car, the stop of the elevator car is determined, and the door opening starts. Five seconds before, the hall lantern flashes and the arrival chime rings in succession. Then, immediately after the passengers get on and off and immediately before the door is closed, the hall lantern stops blinking and turns off. According to the state of the arrival display, the waiter can prepare to get into the elevator car, so that the passenger does not notice or miss the arrival of the elevator car and does not miss or get behind. In addition, such an arrival display allows the passenger to get on and off the elevator car quickly, thereby preventing a decrease in the operating efficiency of the elevator.

[0003] Further, an elevator hall is provided with a car position indicator and a direction indicator (direction light), and the current car position and the operating direction are displayed to a waiting person at the elevator hall. By displaying both the car position and the operation direction, the waiter can give a hint as to how long to wait before the elevator car arrives in a desired direction, and prepares to enter the elevator car accordingly.

Here, when the last call to be answered in the operation direction of the elevator car is only the car call, this call is called the last car call, and stopping in response to the last car call is called the last car call stop. However, how to display the above-mentioned hall lanterns and direction lights when the last car call is stopped is a very difficult choice.

[0005] That is, since the elevator car in the final car call stopped state usually waits only on that floor, it seems that it is not necessary to display either direction, but this causes the following problem. obtain. For example, if a passenger who wants to use the elevator car enters the elevator hall when the last passenger gets off the door, the user is puzzled because it is unknown in which direction the elevator car will be operated. In addition, when customers who want to go to the floors in opposite directions almost simultaneously enter the elevator car, the operation direction of the elevator car is determined as soon as possible by the customer who pressed the destination button in the car, so the destination button must be pressed later. The customer who pushes down immediately or stays on until the operation in the opposite direction ends with patience, and then pushes the destination button of the floor he wants to go to.

[0006] Therefore, in a system in which hall lanterns and direction lights are provided at the elevator hall to display the operation direction, it is common to display a predetermined direction corresponding to the floor. Normally, the floor below and including the first floor displays the ascending direction, the top floor displays the descending direction, and the other floors display the same direction as the direction in which the elevator was moving (hereinafter referred to as the traveling direction). It is supposed to.

However, in the above display, when the elevator car arrives in response to the final car call, a hall call in a direction opposite to the direction indicated and displayed on the elevator hall may be registered. For example, when the vehicle stops in the upward direction by the last car call on the 5th floor, the hall lantern in the upward direction flashes 4 seconds before the door starts to open and the arrival guidance is given. It is assumed that a customer who goes to the floor enters the elevator hall on the fifth floor, presses the hall button, and registers a hall call in the down direction. In this case, after a predetermined door opening time has elapsed, the elevator car is closed once, and after confirming that there is no call to be answered on floors higher than the fifth floor, the elevator car is switched downward and reopened, that is, so-called. , Perform a double door operation. The reason why the direction is not reversed while the door is kept open is to prevent a passenger on the upper floor, who may be in the elevator car, from switching to the down direction before pressing the destination button. . Further, once the door closing operation is performed, the time for pressing the destination button during the door closing operation can be secured, and a new passenger (particularly,
This is because it is possible to prevent a passenger going in the opposite direction from getting on. In this case, even in the case where the hall lantern in the up direction is blinking on the fifth floor, a down call on the fifth floor is forcibly assigned to this elevator car in this case. Although the operation direction is switched immediately, there is a possibility that there is a passenger who got in this elevator car by seeing the blinking of the up hall lantern, so if the operation direction is switched as it is, the passenger will be carried in the opposite direction It can also be. As described above, it is not known whether or not there is a passenger in the elevator car until the car call is registered, so that the direction must be carefully switched.

[0008] However, this double door operation appears to the passengers going to the first floor to be an extremely unnatural operation. That is, although the waiting person at the elevator hall knows at a glance whether or not there is a passenger in the car, he / she feels suspicious why the door closing operation is performed once when there is no person in the car.

Therefore, conventionally, in order to reduce the chance of occurrence of the above-mentioned double door operation, as shown in Japanese Patent Application Laid-Open No. 3-128878, a direction in which a waiting customer at a stopped floor is likely to turn is considered. Learn each,
Lighting of a hall lantern or a direction lamp in that direction is performed.

[0010]

However, in the conventional elevator control apparatus as described above, although it is effective on a floor where the probability of occurrence of passengers in one direction is high and the probability of occurrence of passengers in the other direction is low, it is effective. However, it was not always possible to effectively reduce the occurrence of double-door operations on floors where passenger incidence in both directions was high and almost equal.

When the vehicle arrives in response to the last car call, a hall call may be registered at a place other than the stop floor.
For example, it is assumed that a down call on the third floor is registered when stopping in the up direction at the last car call on the fifth floor. In this case, after the elevator car stops, the door is closed once a predetermined door opening time has elapsed, and after confirming that there is no call to be answered on the floor above the fifth floor, switching to the down direction, the elevator car is switched to the third floor. He was leaving for a down call. However, if the hall lantern in the ascending direction flashes and the customer happens to get into the elevator car and register a car call on the 8th floor while the door is open, the elevator car will travel once to the 8th floor and then descend on the 3rd floor. Since he had to answer the call, the waiting time for the down call on the third floor was long.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an elevator control device capable of reducing the chance of occurrence of a double door operation and the occurrence of a long waiting call.

[0013]

According to the present invention, an elevator control apparatus causes an elevator car to respond to a hall call registration and an in-car call registration by a hall button provided on each floor, and Car control means for performing various controls necessary for the operation of the car, and guiding and displaying the arrival and operation direction of the elevator car on the hall display, and when the elevator car stops in response to the call registration, the elevator car A final car call stop determining means for determining a final car call stop when there is no other call to be answered in front of the traveling direction and stopping only in response to the car call registration on the stop floor,
When a hall call to respond to the floor at which the final car call is stopped occurs after the stop decision, if the arrival and operation direction of the elevator car is not yet displayed on the hall indicator, the operation direction is changed to the hall call. If the arrival and operation directions are changed to the same direction, and the guidance display is started on the hall display, the operation direction control means for maintaining the operation direction as it is; The display device further includes a hall display control means for performing a guidance display according to the operation direction determined by the operation direction control means.

[0014] The elevator control apparatus according to the second aspect of the present invention makes the elevator car respond to hall call registration and in-car call registration by hall buttons arranged on each floor, and is required for the operation of the elevator car. While performing each control,
Car control means for guiding and displaying the arrival and operation direction of the elevator car on the hall display, and when the elevator car stops in response to the call registration, another call to be answered ahead of the traveling direction of the elevator car is issued. No, a final car call stop determining means for determining a final car call stop when stopping only in response to a car call registration at the stop floor, and a final car call stop for the elevator car arriving at the final car call stop. And a landing display control means for delaying the operation start timing of the landing display as compared with when the vehicle arrives at a location other than the above.

According to a third aspect of the present invention, the elevator control apparatus causes the elevator car to respond to hall call registration and in-car call registration by the hall buttons arranged on each floor, and is required for the operation of the elevator car. While performing each control,
Car control means for guiding and displaying the operation direction of the elevator car on the hall indicator, and when the elevator car stops in response to the call registration, there is no other call to respond in the traveling direction ahead of the elevator car, A final car call stop determining means for determining a final car call stop when stopping only in response to a car call registration on a stop floor, and responding in a direction opposite to a traveling direction to a floor where the final car call is stopped after the stop is determined. When a power call occurs, if the operating direction in the same direction as the traveling direction of the elevator car is being displayed on the hall indicator, the operating direction is changed to the opposite direction, and the operation in the opposite direction to the running direction is performed. If the direction is displayed on the hall indicator after the guidance display is started, the direction indicator of the hall indicator is switched with respect to the operation direction control means for maintaining the operation direction as it is and the elevator car for stopping the final car call. Before the timing, a guidance display in the same direction as the traveling direction is displayed on the landing display, and after the direction switching time of the landing display, a guidance display according to the traveling direction determined by the traveling direction control means is displayed on the landing display. Hall display control means.

An elevator control apparatus according to a fourth aspect of the present invention makes the elevator car respond to hall call registration and in-car call registration by hall buttons arranged on each floor, and is required for the operation of the elevator car. While performing each control,

[0017]

In the elevator control apparatus according to the first aspect of the present invention, when the elevator car stops in response to the call registration,
When a hall call to respond to the floor where the final car call stops occurs before the elevator car stop decision is made, if the arrival and operation direction of the elevator car has not yet begun to display guidance on the hall indicator, the operation direction Is changed to the same direction as the hall call, and after the arrival and operation directions are started to be displayed on the hall indicator, the same operation direction is maintained, and the hall indicator is displayed at a predetermined time after the stop is determined. Since the guidance display according to the operation direction is performed, when the elevator car arrives in response to the final car call, if the guidance display is not started, the operation direction desired by the waiting customer at the car stop floor is displayed. be able to.

In the elevator control apparatus according to the second aspect of the present invention, when the elevator car stops in response to the call registration and the stop of the elevator car arrives at the final car call stop, other than the final car call stop Since the operation start time of the hall indicator is delayed and the guidance display of the arrival and operation direction of the elevator car is delayed compared to when arriving at the elevator car, when the elevator car arrives in response to the final car call, A guidance display is provided in the direction of operation desired by the waiter on the car stop floor.

In the elevator control apparatus according to the third aspect of the present invention, when the elevator car stops in response to the call registration, the elevator car stops on the floor where the final car call is stopped before the elevator car is stopped. When a landing call to be answered occurs, the driving direction in the same direction as the traveling direction of the elevator car is displayed on the landing display as a guide, and the driving direction is changed to the driving direction and the driving direction in the opposite direction to the driving direction. After the guidance display is started on the hall indicator, the operating direction is maintained as it is, and for the elevator car that stops the final car call, the traveling direction is displayed on the hall indicator before the direction switching time of the hall indicator. Since the guidance display in the same direction as the above is performed, and the guidance display according to the operation direction is performed on the landing display after the direction switching time of the landing display, the elevator car arrives in response to the final car call. Come, it is possible to guide displays the direction of travel desired by the waiting customer of the cage stop floor from the decision stopped until a predetermined time.

In the elevator control apparatus according to the present invention, when the elevator car stops in response to the call registration, when the elevator car stops in response to the call registration,
When the elevator car stops at the last car call stop, the display switchable time of the operating direction of the hall indicator is delayed and the display switchable period is shorter than when the elevator car stops at the last car call stop. Since the length is increased, when the elevator car arrives in response to the final car call, the guidance display is easily displayed in the direction of operation desired by the waiter on the car stop floor.

The car control unit 12 for the second car is configured similarly to the car control unit 11 for the first car.

Next, the operation of the elevator control apparatus of the present embodiment having the above configuration will be described with reference to FIGS. FIG. 2 is a flowchart showing a final car call stop determination program of the elevator control device according to the first embodiment of the present invention,
The final car call stop determination program showing the procedure for determining the final car call stop at the time of this stop determination is a part of the car control program stored in the memory of the microcomputer constituting the car control unit 11 for the first car. FIG. 3 is a flowchart showing an operation direction control program of the elevator control device according to the first embodiment of the present invention. The operation direction control program, which is also a part of the car control program, sets the operation direction after the stop is determined. Is shown. FIG. 4 is a flowchart showing a hall display control program of the elevator control apparatus according to the first embodiment of the present invention. The hall display control program, which is also a part of the car control program, controls the display operation of the hall lantern. Is shown. The car control program is repeated periodically (for example, every 50 milliseconds).

First, the final car call stop judging program of FIG. 2 will be described.

In FIG. 2, in step S21, it is determined whether or not a stop determination has been made by an operation control program (not shown) executed by the operation control means 11F. Through a series of operations from step S22 to step S28, it is determined whether or not "final car call stop" is performed simultaneously with setting of the operation direction of the elevator car at the time of stop determination. That is, immediately after the stop determination, in step S22, the preceding car position floor ADV (the car position floor preceding the synchronous car position floor SYN corresponding to the actual elevator car position by the deceleration distance corresponding to the current traveling speed). ) Determines whether there is a hall call to be answered in the same direction as the traveling direction RDR (allocated hall call), and if there is the corresponding hall call, the operation direction S is determined in step S24.
DR is set in the same direction as the traveling direction RDR. The traveling direction RDR is control data created in the operation control program, and indicates the direction in which the elevator car is moving from the start of traveling to the stop. After the stop, the elevator car moves before stopping until it departs again. This is data indicating the direction of the vehicle.

On the other hand, if there is no landing call corresponding to the above at step S22, the process proceeds to step S23, where the floor ahead of the preceding car position floor ADV (upward if the traveling direction SDR is up, down if it is down). It is determined whether there is a hall call or a car call to respond to. If there is a hall call or a car call to respond to, the operation direction SDR is set to the same direction as the traveling direction RDR in step S24, If there is no call to be answered, the process proceeds to step S25,
It is determined whether or not there is a hall call to be answered in the direction opposite to the traveling direction RDR at the preceding car position floor ADV. If there is the corresponding hall call, the operation direction SDR is set to the opposite direction of the traveling direction RDR in step S26. If there is no corresponding hall call, the process proceeds to step S27, where the preceding car position floor ADV is set to the minimum. Judge whether it is the lower floor or the top floor.
If it is the lowest floor or the top floor, the operation direction SDR is set to the opposite direction of the traveling direction RDR in step S26, and if the preceding car position floor ADV is neither the bottom floor nor the top floor, the operation direction SDR in step S28. Is set to the same direction as the traveling direction RDR, and "final car call stop" is detected.

With such a series of operations, in the final car call stop determination program, the operation direction SDR of the elevator car is set immediately after the stop is determined, and it is determined whether or not "final car call stop".

Next, the operation direction control program of FIG. 3 will be described.

In FIG. 3, in step S31, it is determined whether or not the elevator car is decelerating (a period from a decision to stop until the car stops) and whether or not "final car call is stopped", and an arrival display operation is performed in step S32. It is determined whether it is before. If the vehicle is decelerating, "final car call stopped", and is in the state before the arrival display, the response generated from the determination of stop to before the arrival display is performed by a series of operations from step S33 to step S38. The operation direction is changed according to the power call.

Steps S33 and S34 are the same as those in FIG.
Are exactly the same as the detection conditions in steps S22 and S23 of the preceding car, and whether the preceding car position floor ADV has a hall call to respond in the same direction as the traveling direction RDR is determined in front of the preceding car position floor ADV (the traveling direction RDR). It is determined whether there is a hall call (allocated hall call) or a car call to be responded to the floor above (if it is up, down if it is down).
If there is a call corresponding to any of the above, step S3
At 5, the driving direction SDR is set to the same direction as the driving direction RDR, and the determination of "final car call stop" is reset. Step S36 is exactly the same as the detection condition of step S25 in FIG. 2, and the traveling direction R is set to the preceding car position floor ADV.
It is determined whether or not there is a hall call to be answered in the opposite direction to DR (allocated hall call). If there is the corresponding hall call, the operation direction SDR is set to the reverse direction of the traveling direction RDR in step S37. If there is no corresponding hall call, the response to the floor behind the preceding car position floor ADV is made in step S38. It is determined whether there is a hall call to be assigned (allocated hall call). If there is a hall call to respond to the rear floor, step S
At 37, the operation direction SDR is set to the opposite direction of the traveling direction RDR, and if there is no hall call to respond to the rear floor, the operation direction SDR set immediately after the stop determination is held.

With such a series of operations, the operation direction control program changes the operation direction according to the call to be answered after the stop is determined and before the arrival display is performed at the time of "final car call stop". The timing in which the operation direction SDR can be set freely is a time within the predetermined period after the stop is determined, a time when the door is closed, and a time when the vehicle is in a non-directional state. In any case, depending on the presence or absence of a call to be answered and the positional relationship between the preceding car position floor ADV and the call to be answered, the operation direction SDR is set to no direction or set to a direction toward a new call to be answered. However, these actions are well known,
Further, since it is not directly related to the present invention, the detailed description is omitted here.

Next, the hall display control program of FIG. 4 will be described.

In FIG. 4, in step S41, it is determined whether or not the elevator car of the first car has arrived and displayed. If it is immediately after the elevator car is determined to be stopped, since the arrival display (the blinking of the hall lantern) has not been started yet, the process proceeds from step S41 to step S42, where it is determined whether or not the last car call has been stopped.

If it is not "final car call stop",
Proceeding to step S43, the elevator car is opened before door opening T
It is determined whether the vehicle has approached a position within one second (for example, four seconds). If the vehicle is not approaching the position within T1 seconds before the opening of the door, the arrival display is not started. However, if the vehicle is approaching the position within T1 seconds before the opening of the door, in step S44, in the operation direction SDR set at this time. The hall lantern in the corresponding direction starts blinking and the arrival chime sounds.

On the other hand, in the case of "final car call stop" in step S42, the flow advances to step S45 to determine whether the elevator car has approached a position within T2 seconds (T2 <T1, for example, 0 second) before the door opening starts. Judge. Before door opening T2
If the vehicle is not approaching the position within seconds, the arrival display is not started. However, if the vehicle is approaching the position within T2 seconds before the door opening starts, in the same manner as described above, in step S44, it corresponds to the operation direction SDR set at this time. Start the blinking of the hall lantern in the direction you want to sound the arrival chime.

It should be noted that the end time of the arrival display is the same regardless of whether or not "final car call is stopped", and it is determined in step S46 whether or not the door closing has just been completed. In this case, the hall lantern is turned off in step S47, and the determination of "final car call stop" is reset.

With such a series of operations, in the hall display control program, the arrival display start time is changed depending on whether or not "final car call stop", and the up hall lanterns B1u to B7u on the first to seventh floors and the second floor are displayed. It controls the lighting of the down hall lanterns B2d to B8d and the sounding of the arrival chime (not shown) on the 8th floor.

Here, the operation of this embodiment will be described based on a specific example with reference to FIG. FIG. 5 is an operation explanatory diagram of the elevator control device according to the first embodiment of the present invention.

As shown in FIG. 5, it is assumed that the elevator car 1a for the first car leaving the first floor is determined to stop in response to the car call on the fifth floor. At this time, the traveling direction RDR is “up”, and the final car call stop determination program determines the traveling direction SDR.
Set R to “up” and “final car call stop”
Is determined.

Conventionally, irrespective of the "last car call stop", the hall lantern B5u in the descending direction flashes four seconds before the door opening starts according to the operation direction determined at the time of the stop decision to determine the arrival of the elevator car and the service direction. Display guidance. Therefore, if the down call 5d on the fifth floor is registered between the time when the stop is determined and the time when the arrival display time comes, the double door operation is performed as described above.

However, in this embodiment, in the case of "final car call stop", the hall display control program delays the arrival display time until the door opening start time. Further, in the operation direction control program, if the down call 5d on the fifth floor is registered by the arrival display time (at the start of door opening) after the stop is determined, the operation direction SDR is changed from "up" to "down". . And
According to the hall display control program, when the elevator car approaches the position at the start of the door opening, the hall lantern B5d in the downward direction moves downward.
Flashes to indicate the arrival and service direction at the landing.
Therefore, it is not a double door operation.

As described above, the elevator control apparatus according to the present embodiment provides services for a plurality of floors from the first floor to the eighth floor.
The two elevator cars 1a and 2a for the first and second cars, the hall buttons A1 to A8 respectively provided on each floor to call the elevator cars, and the hall calls are registered when the hall buttons A1 to A8 are operated. A hall call registration means 10A, a car allocation means 10B for selecting and allocating an elevator car to respond to the hall call, ascending hall lanterns B1u to B7u and descending hall lanterns B2d to B provided in the directions of each elevator car hall. B8d, a car call registration unit 11A for registering a car call in the elevator car, an elevator car responding to the car call and the hall call assigned by the car assignment unit 10B, and the up hall lanterns B1u to B7u. Or operate the down hall lanterns B2d to B8d to arrive and operate the elevator car 1 to guide toward the elevator hall
In the group control elevator having the car control units 11 and 12 for the No. 2 and No. 2 units, when the elevator car stops in response to the call, there is no call to respond in the traveling direction RDR ahead of the car position floor, and When it is detected that the car stops only in response to the car call on the car position floor, it is determined that "final car call is stopped". When a hall call to respond to a certain floor occurs, if the arrival and operation direction of the elevator car are not yet displayed on the hall indicator, the operation direction is changed to the same direction as the hall call, and the elevator car The operation direction control means 11B which performs the operation shown in FIG. 3 for maintaining the operation direction as it is after the guidance display of the arrival and operation direction of the vehicle has been started on the hall display.
4. At a predetermined time after the stop is determined, the hall display control means 11 performs the operation shown in FIG. 4 to guide and display the operation direction determined by the operation direction control means 11B on the hall display.
C.

That is, the elevator control device of the present embodiment
A group management unit 10 that is a group management unit that performs group management by allocating elevator cars of the first and second units (a plurality of units) in accordance with hall call registration by the hall buttons A1 to A8 arranged on each floor.
The elevator car responds to the car assignment and the car call registration of the group management unit 10 (group management means), and controls the operation direction, the operation, and the opening / closing of the car door required for the operation of the elevator car. , And the arrival and operation directions of the elevator car are determined by the up hall lanterns B1u to B7u or the down hall lantern B.
When the elevator car stops in response to the call registration with the car control units 11 and 12 for the first car and the second car, which are car control means for displaying guidance on 2d to B8d, the stop of the elevator car is "final". A final car call stop determining means 11E for determining whether or not "car call stop" is performed, and when a hall call to respond to a floor at which the final car call is stopped occurs after the stop decision, the arrival and operation direction of the elevator car are raised. Hole lanterns B1u to B7u or downhole lanterns B2d
To B8d before the guidance display is started, the operation direction control means 11B capable of changing the operation direction, and the uphole lanterns B1u to B7u at a predetermined time after the stop is determined.
Alternatively, a hall display control unit 11C for performing guidance display according to the operation direction determined by the operation direction control unit 11B is provided on the down hall lanterns B2d to B8d.

When the elevator car stops in response to the call registration, when a floor call to be answered occurs on the floor where the final car call stops before the elevator car is determined to stop, the arrival of the elevator car and The operation direction is ascending hole lanterns B1u to B7u or descending hole lanterns B
If the guidance display is not started at 2d to B8d, the operation direction is changed to the same direction as the hall call, and the arrival and operation directions of the elevator car are changed to the uphole lanterns B1u to B7u.
Or, after the guidance display is started on the down hall lanterns B2d to B8d, the operation direction is maintained, and the guidance display according to the operation direction is stopped on the up hall lanterns B1u to B7u or the down hall lanterns B2d to B8d. At a predetermined time after the decision.

Therefore, in this embodiment, when the elevator car "stops the last car call", the operation set at the time of the stop decision according to the position of the call to be answered after the stop decision is made until the arrival display is started. The direction can be changed, and the guidance display is changed to the operation direction desired by the waiter. For this reason, it is possible to reduce the occurrence of double door operation when a landing call to be answered in the direction opposite to the operation direction occurs on the preceding car position floor. Furthermore, even when a landing call to be answered other than the preceding car position floor occurs, if the arrival display is not started, the operation direction can be changed to the direction toward the call, and passengers entering in the opposite direction can be boarded. Can be prevented. For this reason, it is possible to reduce the chance that the waiting time for the hall call becomes longer due to unexpected passengers entering in the opposite direction.

Further, in this embodiment, the group management unit 10 as the group management unit, the car control units 11 and 12 for the first and second units as the car control units, and the stop of the elevator car are referred to as “final car call”. The final car call stop determining means 11E which determines whether or not "stop" is performed, and the elevator car which stops the final car call is moved up from the first floor to the seventh floor as compared with when the arrival of the elevator car is stopped except for the final car call stop. Hall display control means 11C for delaying the guidance display start time of the hall lanterns B1u to B7u and the down hall lanterns B2d to B8d on the second to eighth floors.

In the case of "final car call stop", the arrival display start time is delayed until the door opening start to extend the period in which the operation direction at the time of the stop decision can be changed. The occurrence of a double door operation when a landing call to be answered occurs can be further reduced. In particular, when the traveling distance to the next stop floor is short, the stop determination time may coincide with the time within T1 before the door opening starts, but even in such a case, there is an effect that the occurrence of double door operation can be reduced. Further, even when a hall call to be answered other than at the preceding car position floor occurs, it is possible to reduce the chance that the waiting time of the hall call becomes longer by the delay of the arrival display start time.

By the way, in the above embodiment, if it is detected that there is no call to be answered in the traveling direction ahead of the preceding car position floor and the vehicle stops only in response to the car call of the preceding car position floor, the preceding car position floor is detected. Is determined (step S28 in FIG. 2) regardless of whether or not there is a hall call to be answered on the floor behind. Even if there is a hall call to respond on the floor behind the preceding car position floor,
The judgment of `` final car call stop '' is because if a hall call in the same direction as the traveling direction occurs on the preceding car position floor after the stop decision, the arrival indication is displayed so that it can preferentially respond to the hall call in the same direction. This is to extend the final decision on the direction of operation until the start time. If there is no need for such a priority response, when there is a hall call to be answered on the floor behind the preceding car position floor, set the operation direction to the direction opposite to the traveling direction and say `` final car call stop '' What is necessary is just to make it not to judge.

In the above embodiment, the arrival display start time is set to T1 second (4 seconds) and T2 second (0 second) before the door opening starts. However, the present invention is not limited to this. For example, the set time may be changed according to the arrangement and the number of the elevator cars, or each may be set according to the distance to the stop position, and various other methods are conceivable.

Further, in the above embodiment, if it is determined that the last car call has been stopped and before the arrival display is made, the preceding car position floor is assigned to a landing call in the direction opposite to the traveling direction, or When assigned to a hall call on the floor behind the position floor, the operation direction is set to the opposite direction to the traveling direction, but the determination of “final car call stop” is not reset (FIG. 3).
Step S37). The reason for not resetting the "last car call stop" determination is that, after setting the operation direction to the opposite direction to the traveling direction, if a landing call occurs in the same direction as the traveling direction on the preceding car position floor, This is because the arrival display time is delayed until before the opening, so that the traveling direction can be changed to the same direction as the traveling direction, whereby it is possible to preferentially respond to a hall call in the same direction.

However, in the case where the operation direction is determined in accordance with the hall call position registered previously and the service is provided in the operation direction at this time, step S37 in FIG.
Then, the determination of "final car call stop" may be reset. In this case, after the operation direction is determined and fixed according to the position of the hall call, the arrival display is performed when the elevator car approaches a position within T1 (4 seconds) before the door opening starts as in the normal case. become. Of course, the effect of reducing the occurrence of double door operation and the occurrence of long waiting calls is the same as in the above embodiment.

Further, in the above embodiment, the hall lantern provided in the elevator hall is usually turned off, and when the elevator car arrives in response to the call, the arrival notification and service direction guidance are sent to the hall waiter. What you do is shown. As a hall indicator other than the hall lantern, a hall indicator in which a car position indicator and a direction light are juxtaposed may be installed.

This type of landing indicator is different from a hall lantern that displays only when an elevator car has arrived at that floor, and always has a car position floor (generally using a synchronous car position floor SYN) and the current car position floor. It functions as an indicator that displays the operating direction at the landing. Therefore, only when there is no call to be answered in the front of the traveling direction and the service to the call in the opposite direction becomes possible, it is possible to switch between the up and down hallway direction lights.

For example, if there is no call to be answered on the floor ahead of the preceding car position floor ADV in the traveling direction and there is a hall call to be answered in the preceding car position floor ADV in the opposite direction, usually the preceding car position floor ADV When the ADV and the synchronous car position floor SYN coincide with each other, switching to the landing direction light in the opposite direction to the operation direction is performed. This is because it is considered that there is a waiter waiting for the elevator car to arrive at the landing while watching the landing indicator.
If the direction light is switched when the synchronous car position floor SYN is shifted from V, the direction of movement of the car position lamp (corresponding to the synchronous car position floor SYN) and the lighting direction of the landing direction light are different, so that the waiter is distrusted. The reason is that if the switching time is delayed too much, the waiter may not notice it if the switching time is too late, which may lead to a failure to ride.

Other problems related to the switching of the landing direction lights are, for example, that the down direction lights are turned on from the state in which the up direction lights are turned on, and that the time is short (for example, 3 seconds).
Thus, a phenomenon in which the landing direction light flaps at the time of direction switching, such as the upward direction light being turned on again, is considered. Such a fluttering phenomenon of the hall indicator light is not preferable because it disturbs a waiter looking at the hall indicator. In particular, in the case of “final car call stop”, such a fluttering phenomenon of the hall indicator light tends to occur because there is a degree of freedom in setting the operation direction.

<Second Embodiment> Then, in the case of "final car call stop", the occurrence of the double door operation or the long wait call without causing the fluttering phenomenon of the hall indicator light as described above. An embodiment capable of reducing the number will be described with reference to FIGS. 6 and 7. FIG. Although FIGS. 1 and 2 of the first embodiment are used as they are, the ascending hall lanterns B1u to B7u on the first to seventh floors in FIG. 1 are respectively provided in the ascending direction provided at the elevator landings on the first to seventh floors. The down hall lanterns B2d to B8d on the 2nd to 8th floors are replaced with the downlights provided at the elevator halls on the 2nd to 8th floors.

FIG. 6 is a flowchart showing an operation direction control program of the elevator control device according to the second embodiment of the present invention, which corresponds to FIG. 3 of the first embodiment. FIG. 7 is a flowchart showing a landing display control program of the elevator control device according to the second embodiment of the present invention, and corresponds to FIG. 4 of the first embodiment.

First, the operation of the operation direction control program shown in FIG. 6 will be described.

In FIG. 6, in step S61, it is determined whether or not the elevator car is decelerating (a period from the decision to stop until the car stops) and whether or not "final car call is stopped". It is determined whether the landing direction light is in the opposite direction to the traveling direction. If the vehicle is decelerating, "final car call is stopped", and the landing direction light in the direction opposite to the traveling direction is not on, then steps S63 to S68 are performed.
The operation direction is changed in accordance with the call to be answered, which is generated after the stop is determined and before the arrival display is performed.

Steps S63 and S64 are the same as those in FIG.
Are exactly the same as the detection conditions in steps S22 and S23 of the preceding car, and whether the preceding car position floor ADV has a hall call to respond in the same direction as the traveling direction RDR is determined in front of the preceding car position floor ADV (the traveling direction RDR). It is determined whether there is a hall call (allocated hall call) or a car call to be responded to the floor above (if it is up, down if it is down).
If there is a call corresponding to any of the above, step S6
At 5, the driving direction SDR is set to the same direction as the driving direction RDR, and the determination of "final car call stop" is reset. Step S66 is exactly the same as the detection condition of step S25 in FIG. 2, and the traveling direction R is set to the preceding car position floor ADV.
It is determined whether or not there is a hall call to be answered in the opposite direction to DR (allocated hall call). If there is the corresponding hall call, the operation direction SDR is set to the reverse direction of the traveling direction RDR in step S67. If there is no corresponding hall call, the response to the floor behind the preceding car position floor ADV is made in step S68. It is determined whether there is a hall call to be assigned (allocated hall call). If there is a hall call to respond to the rear floor, step S
At 67, the operation direction SDR is set to the opposite direction to the traveling direction RDR, and if there is no hall call to respond to the rear floor, the operation direction SDR set immediately after the stop decision is held.

According to the series of operations, the driving direction control program determines that the "final car call is stopped" and the driving direction R
When the direction light in the direction opposite to DR is not turned on, the operation direction is determined according to the position of the call to be answered after the stop determination. The timing in which the operation direction SDR can be set freely is a time within the predetermined period after the stop is determined, a time when the door is closed, and a time when the vehicle is in a non-directional state. In any case, depending on the presence or absence of a call to be answered and the positional relationship between the preceding car position floor ADV and the call to be answered, the operation direction SDR is set to no direction or set to a direction toward a new call to be answered. However, since these operations are well-known and are not directly related to the present invention, detailed description is omitted here.

Next, the hall display control program of FIG. 7 will be described.

In FIG. 7, in step S71, it is determined whether the elevator car of the first car is running or stopped. If the elevator car is stopped, the operation direction SDR has already been determined, so the process proceeds from step S71 to step S72, where the direction light in the same direction as the operation direction SDR (the upward direction if the operation direction SDR is ascending) All the lights B1u to B7u, and if down, all the down lights B2d to B8d) are turned on. If the operation direction SDR is set to no direction by the operation direction control program, the upward direction light B1
u to B7u and the down lights B2d to B8d are all turned off. At the same time, "final car call stop" in preparation for the next call answer
Is reset.

If the elevator car is traveling, but has not started decelerating, the process proceeds from step S71 to step S73 and further to step S74, where the direction light in the same direction as the traveling direction RDR (the traveling direction RDR is In the case of ascending, all of the ascending direction lights B1u to B7u are lit, and in the case of descending, all of the ascending direction lights B2d to B8d.

If the elevator car is determined to stop and is decelerating, the process proceeds from step S73 to step S75, where it is determined whether or not "final car call stop". If it is not "final car call stop", the operation direction SDR is determined, so the process proceeds to step S76, where the direction lights in the same direction as the operation direction SDR (the up direction lights B1u to B7u if the operation direction SDR is up). , If it is down, the down light B2d
To B8d). If "final car call stopped" in step S75, the process proceeds to step S77.
Here, it is determined whether or not the elevator car has approached a position appropriate for switching the landing direction light (preceding car position floor ADV = synchronous car position floor SYN). Note that the timing at which the switching of the hall indicator lights becomes possible for the first time is the same as in the case where "final car call stop" is not performed.

Now, in step S77, the preceding car position floor A
If the elevator car has not yet approached a position where the DV and the synchronous car position floor SYN coincide, the operating direction SD
Even if a new assigned hall call that sets R in the opposite direction is generated, switching to the opposite direction hallway light is suppressed. That is, the operation direction S depends on the occurrence of a new landing call to be answered.
Assuming that the review of the DR is still possible, step S74
Then, all the direction lights in the same direction as the traveling direction RDR are kept on.

On the other hand, the elevator car is located at the preceding car position floor A
When the vehicle approaches the position where the DV and the synchronous car position floor SYN coincide with each other, and it is possible to switch to the hall indicator in the opposite direction,
Proceeding to step S78, thereafter, the suppression of switching to the landing direction light in the opposite direction is released. Note that the last time when switching to the landing direction light in the opposite direction is possible (= the last time when switching is possible)
Is the time T2 seconds before the elevator car starts to open (for example, 0
Second). Step S
At 78, it is determined whether or not the operation direction SDR and the traveling direction RDR set at each time point are the same during the period in which the switching to the landing direction light in the opposite direction is possible.

If it is detected in step S78 that the driving direction SDR and the driving direction RDR are not the same, it means that an assigned hall call for setting the driving direction to the reverse direction has been newly generated after the stop decision. Therefore, the operation direction SDR at this time is fixed, and the
Turns on all the direction lights in the same direction as the operation direction SDR (that is, the direction opposite to the traveling direction RDR). Step S78
If the operation direction SDR and the traveling direction RDR are still the same, it is next determined in step S79 whether or not the final switching is possible. If the elevator car has not approached the position within T2 seconds (for example, 0 seconds) before the door opening starts, the operation direction S may be newly generated due to the assigned landing call.
DR can be set in the opposite direction. That is, in order to enable lighting of the direction light in the direction opposite to the traveling direction RDR, all the direction lights in the same direction as the traveling direction RDR are continued to be lit in step S74 in the same manner as described above.

When it is detected in step S79 that the elevator car has approached the position within T2 seconds before the start of door opening and it is time to finally switch to the landing indicator light in the opposite direction, it is switched to the landing direction light in the opposite direction thereafter. And all the direction lights in the same direction as the driving direction SDR are turned on in step S72 in the same manner as described above.

According to such a series of operations, in the hall display control program, in the case of “final car call stop”, according to the approach state of the elevator car and the set operation direction,
Uplights B1u to B7u and downlights B2d on each floor
The lighting of B8d is controlled.

As described above, the elevator control apparatus according to the present embodiment provides a group management unit 10 similar to that of the first embodiment, a car assignment by the group management unit 10 (group management means), and registration of a call in the car. To make the elevator car respond, and perform various controls such as operation direction control, operation control, and opening / closing control of the car door necessary for the operation of the elevator car, and also change the operation direction to the uplight B1u to B7u or the downlight. B2d-B
The car control units 11 and 12 for car Nos. 1 and 2 which are car control means for displaying guidance on 8d, the last car call stop judging means 11E similar to the first embodiment, and the last car call after the stop decision. When a landing call to be answered in the opposite direction to the traveling direction occurs on the floor at which the vehicle stops, the operation direction in the same direction as the traveling direction of the elevator car is displayed on the ascending lights B1u to B7u or the descending lights B2d to B8d. If so, the operation direction is changed to the direction opposite to the traveling direction, and the operation direction opposite to the traveling direction is changed to the up direction lights B1u to B7u or the down direction lights B.
If the guidance display is started at 2d to B8d, the operation direction control means 11B for performing the operation of FIG. 6 for maintaining the operation direction as it is and the elevator car for stopping the last car call, and Before the direction switching time of the lights B1u to B7u or the down lights B2d to B8d, the ascending lights B1u to B7u or the down lights B2d to B8d provide guidance display in the same direction as the traveling direction, and the up light B1u to
After the direction switching time of B7u or the down light B2d to B8d, the up light B1u to B7u or the down light B2
d to B8d are provided with hall display control means 11C for performing the operation shown in FIG. 7 for performing guidance display according to the operation direction determined by the operation direction control means 11B.

Therefore, in the present embodiment, when the elevator car "stops the final car call", a new time is required until the predetermined time (= the time when the last switch to the landing direction light in the opposite direction is possible) after the stop is determined. The operation direction set at the time of the stop decision can be changed in the opposite direction to the traveling direction according to the generated call position to be answered, and the guidance display is changed to the operation direction desired by the waiter. For this reason, it is possible to reduce the occurrence of double door operation when a landing call to be answered in the direction opposite to the operation direction occurs on the preceding car position floor. In addition, even if there is a hall call to respond to other than the preceding car position floor,
Until the final switchover time to the hall indicator in the opposite direction, the operation direction can be changed in the direction toward the call, and the passengers in the opposite direction can be prevented from getting in. For this reason, it is possible to reduce the chance that the waiting time for the hall call becomes longer due to unexpected passengers entering in the opposite direction.

In the present embodiment, the group management unit 10 as the group management unit, the car control units 11 and 12 for the first and second units as the car control units, and the stop of the elevator car are referred to as “final”. A final car call stop determining means 11E for determining whether or not "car call stop" is performed, and an elevator car for stopping the final car call is compared with the elevator car for stopping the arrival at a time other than the final car call stop, from the first floor to the seventh floor. Hall display control means 11C for delaying the last possible timing of the direction change of the ascending indicator lights B1u to B7u and the descending indicator lights B2d to B8d of the second to eighth floors.

In the case of "final car call stop", the last switchable time to the hall indicator light in the opposite direction to the traveling direction is delayed until the door opening starts, and the operation direction at the time of the stop decision is changed to the opposite direction to the traveling direction. Since the possible period is lengthened, it is possible to further reduce the occurrence of double door operation and long waiting calls when a landing call to be answered in the direction opposite to the traveling direction occurs on the preceding car position floor. In particular, when the traveling distance to the next stop floor is short, the stop decision time and the normal landing direction switch time (preceding car position floor ADV = synchronous car position floor SYN)
) May be very short, but even in such a case, there is an effect that the occurrence of double door operation can be reduced. Furthermore, even when a hall call to be answered other than at the preceding car position floor occurs, the chance of waiting time for the above hall call becoming longer by the delay of the last switchable time to the hallway light in the opposite direction is reduced. it can. Furthermore, once the landing indicator light in the direction opposite to the traveling direction has been lit, the landing direction light in the same direction as the traveling direction cannot be illuminated thereafter, so that fluttering of the landing direction light can be suppressed, and double door operation and Opportunities for long waiting calls can be reduced.

By the way, in the above embodiment, when it is detected that there is no call to be answered in the traveling direction ahead of the preceding car position floor and the vehicle stops only in response to the car call at the preceding car position floor, the preceding car position floor is detected. Is determined (step S28 in FIG. 2) regardless of whether or not there is a hall call to be answered on the floor behind. Even if there is a hall call to respond on the floor behind the preceding car position floor,
The judgment of `` final car call stop '' is made when a landing call in the same direction as the traveling direction occurs on the preceding car position position floor from the stop decision to the switching restraint release timing to the opposite direction of the landing direction light, This is to extend the final decision on the direction of operation so that priority can be given to landing calls in the same direction. If there is no need for such a priority response, when there is a hall call to be responded to on the floor behind the preceding car position floor, it may be determined that "final car call stop" is not determined.

In the above-described embodiment, the last switchable time to the landing direction light in the direction opposite to the traveling direction at the time of “last car call stop” is T2 seconds (0 second) before the door opening starts. The setting method is not limited to this. For example, the set time may be changed according to the arrangement and the number of the elevator cars, or each may be set according to the distance to the stop position, and various other methods are conceivable.
At least after the normal landing direction light switching time (at the time when the preceding car position floor ADV = the synchronous car position floor SYN) and before the door opening starts, the final switchable time may be set. . In this case, the period from the switching time of the normal landing direction light to the final switchable time to the opposite direction lighting is the switchable period of the opposite direction indicator light.

In the above-described embodiment, the landing direction light is switched immediately when the operation direction is switched to the reverse direction during the switching period of the landing indicator light in the opposite direction. The timing of switching the direction lights is not limited to this. It may be any time during the above-mentioned switchable period, or may be always delayed until the final switchable time.

Further, in each of the above-described embodiments, the case where two elevator cars are provided has been described. However, the present invention is naturally applicable to three or more group control elevators, and is applied to an elevator in which only one elevator car is installed. Can also be applied. In the case where the number of elevator cars is one, the group management means becomes unnecessary.
