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 last car call, a display is displayed.
There is a case where a hall call in the opposite direction to the operating direction is 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, a passenger going in the opposite direction) can be prevented from getting on. is there.

[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] On the other hand, the service status (waiting time) and type (call for wheelchairs, call for guest, etc.) for the hall call
In some cases, the elevator car currently in service can be emptied quickly (by leaving the elevator car closed without any call to respond) to rescue long-awaited or crowded calls Sometimes, you may want to respond to a dedicated call quickly. In such a case, a method of restricting the assignment of a new hall call to the elevator car to be emptied has been conventionally employed.

[0011]

However, in the conventional elevator control apparatus as described above, even when it is desired to quickly put the elevator car into the empty car state, the elevator hall of the elevator car with the door open at the final car call stoppage. In some cases, a passenger who came in the same direction as the operation direction came in, checked the hall lantern and direction lights, and got into the elevator car with the door open. In this case, since the newly registered car call must be answered, the elevator car is delayed from being empty by that much. In particular, at the time of the final car call stop, the elevator car is stopped by turning on the hall lantern or the direction light in the direction where the waiter is likely to turn on the floor to be stopped in order to reduce the chance of double door operation occurring. In such a case, it was difficult to make the elevator car empty even though the elevator car was desired to be put in the empty car state quickly.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an elevator control device that can quickly bring an elevator car that has stopped a final car call into an empty car state when an empty car is required.

FIG. 3 is a flowchart showing a hall display control program of the elevator control device according to the first embodiment of the present invention. The hall display control program, which is also a part of the car control program, shows a procedure for controlling a hall lantern display operation. I have. The group management unit program and the car control program are repeated periodically (for example, every 100 milliseconds).

First, the stop direction designation program shown in FIG. 2 will be described.

In FIG. 2, steps S101 to S108 are arithmetic programs for the first to eighth floors, respectively, and accumulate the number of hall calls generated on each floor in each direction, compare these magnitudes and stop. From direction S [1] to S
Set [8]. The setting operation of the direction to be stopped will be described with reference to a calculation program for the fifth floor (step S105). The operation programs of floors other than the fifth floor operate in the same manner.

If the beginning of the day (0:00 a.m.) is detected in step S111, both the up call counter N5u and the down call counter N5d are set to "0" in step S112.
Reset to. Thereafter, the direction to be stopped is set in steps S113 to S119.

If it is detected in step S113 that the up call for the fifth floor has just been registered, step S114
Increments the up call counter N5u by "1". If it is detected in step S115 that the down call on the fifth floor has just been registered, the down call counter N5d is incremented by "1" in step S116. Then, in a step S117, it is determined whether or not N5d ≧ N5u.
In the case of 5u, the stop designation direction S [5] is determined in step S118.
Is set to “up”, and if N5d <N5u, the stop designation direction S [5] is set to “down” in step S119.

By such a series of operations, the stop determination designation program obtains the number of hall calls generated in each direction on each floor, and
The direction in which this is smaller is set as the direction to stop.

Next, the final car call stop judging program of FIG. 3 will be described.

In FIG. 3, 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 stopped" at the same time as the setting of the operating direction of the elevator car at the time of the 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 RDR 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, the final car call stop determination program sets the operation direction SDR of the elevator car immediately after the stop is determined, and determines whether or not "final car call stop".

Next, the operation direction control program of FIG. 4 will be described.

In FIG. 4, in step S31, it is determined whether or not the elevator car is decelerating (a period from a stop decision to a stop) and "final car call 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 a state before the arrival display, the response generated after the stop is determined and before the arrival display is performed by a series of operations from step S33 to step S40. The operation direction is changed depending on whether there is a power call or an empty car request command.

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
In step 5, the operation direction SDR is set to the same direction as the traveling 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. 3, 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 a corresponding hall call, the operation direction SDR is set to the opposite direction of the traveling direction RDR in step S37. If there is no corresponding hall call, whether an empty car request command has been issued to the first car in step S38. Determine whether or not. If the empty car request command has not been issued, it is determined in step S39 whether or not there is a hall call (allocated hall call) to respond to the floor behind the preceding car position floor ADV. 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 decision is held.

On the other hand, if the empty car request command is issued to the first car in step S38, the operation direction S is determined in step S40.
DR is set to the stop designation direction S [ADV] (= the direction in which the frequency of occurrence of passengers by direction at the preceding car position floor ADV is lower) set by the stop designation program.

With such a series of operations, in the operation direction control program, when "final car call is stopped", the call to be answered after the stop is determined and before the arrival display is performed, the presence or absence of an empty car request command, and The operation direction is changed according to the designated stop direction based on the passenger occurrence rate for each direction. In addition,
The time during which the operation direction SDR can be freely set is a time within the predetermined period after the stop is determined, a time when the door is completely closed, and a time when the vehicle is in the non-direction. 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,
Although the operation direction SDR is set to a non-direction or a direction toward a call to be newly answered, these operations are well-known and are not directly related to the present invention. Description is omitted.

Next, the hall display control program of FIG. 5 will be described.

In FIG. 5, in step S51, the elevator car of the first car starts the arrival display and determines whether or not the arrival is being displayed. If it is immediately after the elevator car is determined to stop, the arrival display (the blinking of the hall lantern) has not been started yet, so the process proceeds from step S51 to step S52, where the elevator car is T seconds before the door opening starts (for example,
(4 seconds) or not. If the position is not approached within T seconds before the door opening start, the arrival display is not started, but if the approaching position is within T seconds before the door opening start,
In step S53, the hall lantern in the direction corresponding to the operation direction SDR set at this time is started to blink, and the arrival chime is sounded.

On the other hand, if it is determined in step S51 that the arrival is being displayed, the hall lantern in the same direction as the operation direction SDR is kept blinking until it is detected in step S54 that the door is about to be closed. Then, immediately before the door closing is completed, the hall lantern is turned off in step S55, and the determination of “final car call stop” is reset.

With such a series of operations, according to the hall display control program, lighting and arrival of the up hall lanterns B1u to B7u on the first to seventh floors and the down hall lanterns B2d to B8d on the second to eighth floors according to the operation direction SDR. Each chime (not shown) is controlled.

Here, the operation of this embodiment will be described based on a specific example with reference to FIG. FIG. 6 is an operation explanatory diagram of the elevator control device according to the first embodiment of the present invention.

As shown in FIG. 6, when an empty car request command is issued to the first car, the elevator car 1a for the first car departing from the eighth floor is determined to stop in response to the car call on the fifth floor. And At this time, the value of the up call counter N5u on the fifth floor is 56, and the value of the down call counter N5d is 3
It is assumed that the stop designation direction S [5] is set to “up” by 21 pieces.

At this time, the traveling direction RDR of the first car is "down", and the final car call stop determination program sets the operation direction SDR to "down" and determines "final car call stop". If there is no new call to be answered immediately before the arrival display starts, the operation direction SDR is “up” according to the stop specification direction S [5] (= “up”) set by the stop direction specification program. Changed,
The hall display lantern B5u in the upward direction is blinked by the hall display control program, and the arrival and the service direction of the elevator car are displayed on the hall as a guide.

Normally, the first car stops in the “down” direction, which is the same direction as the traveling direction RDR, and blinks the hall lantern B5d in the down direction to indicate the arrival service direction at the elevator hall. When the empty car request command is issued, the ascending hall lantern B5u, which has a low probability of occurrence of passengers, is operated and stopped, so that the first car easily becomes an empty car on the fifth floor. Moreover, even if a down call is registered on the 5th floor, a new hall call will not be assigned to the first car that has issued an empty car request command,
There is no worry about double door operation in response to this down call.

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.

The up hall lanterns B1u to B7u or the down hall lanterns B2d to B8d in the direction in which the frequency of occurrence of passengers by each direction is low are displayed. If no empty car request command is issued from the empty car request means 10C, the stop direction designation is performed. The uphole lanterns B1u to B7u or the downhole lanterns B2d to B8d are displayed irrespective of the designation by the means 10D.

Therefore, in the present embodiment, when the elevator car stops in response to the last car call, and when no empty car request command is issued, on the floors other than the terminal floor,
Stops by operating the hall lantern in the same direction as the traveling direction, but stops when the empty car request command is issued by operating the hall lantern in the direction with the lowest frequency of passenger occurrence by direction at the floor to be stopped I do. For this reason, the possibility that passengers entering the elevator hall after the start of arrival display will enter the elevator car in the final car call stop state is reduced, and the elevator car that has received the empty car request command is quickly changed to the empty car state by that much. can do. As a result, when an empty car is required, by displaying a landing in a direction in which the probability of a waiting customer on the floor to be stopped is low, it is possible to minimize the entry of customers into the elevator car. The empty elevator car can be emptied quickly,
When an empty car is not required, a hall with high serviceability can be displayed for waiting customers on the stop floor, so that the service for waiting customers is improved.

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. 3) regardless of whether there is a hall call to be answered on the floor behind the vehicle. When there is a hall call to be answered behind the preceding car position floor, it is also possible to set the operation direction to the direction opposite to the traveling direction and stop it without determining `` final car call stop '', but as always When the floor is turned over and stopped, the possibility of passengers in the opposite direction to the traveling direction being higher than the possibility of passengers in the traveling direction being higher is the empty car state on that floor. You will be late. Therefore, in the above embodiment, even when there is a hall call to respond to a floor behind the preceding car position floor,
By determining that the last car call has been stopped, if an empty car request command has been issued, the hall lantern in the direction in which the frequency of occurrence of passengers by direction is low can be blinked and stopped. Of course, when there is a hall call to be responded to on the floor behind the preceding car position floor, even if the operation direction is set to the opposite direction to the traveling direction so that it is not determined to be "final car call stop", The effect can be sufficiently obtained.

In the above embodiment, the time at which the arrival display is started is T seconds (4 seconds) before the door opening starts, but the method of setting the time at which the arrival display is started 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.

In the above embodiment, when the empty car request command is not issued, the elevator car is stopped by operating the hall lantern in the same direction as the traveling direction on the floors other than the terminal floor. The method of determining the direction in which the hall lantern is turned on when no command is issued is not necessarily limited to this. For example, when the empty car request command is not issued, the hall lantern in the direction in which the frequency of occurrence of passengers by direction on the floor to be stopped may be operated and stopped may be operated. In this case, it is possible to reduce the occurrence of double-door operation when a landing call to be answered in the opposite direction to the operation direction occurs at the car position floor.

Further, in the above embodiment, the number of occurrences of ascending calls and descending calls for each floor is obtained as a cumulative value from the beginning of the day.
Although this is treated as the passenger occurrence frequency for each direction, what indicates the possibility of the passenger getting in for each direction is not limited to this. For example, by detecting a change in the output of a weighing device provided on a car floor, the weights of passengers and disembarking passengers can be obtained for each service floor for each floor, and this can be used as a passenger occurrence frequency for each direction, A sensor for detecting the number of passengers may be installed above the entrance of the car, and the number of passengers may be obtained for each service floor for each floor. In addition, the number of hall calls from the beginning of the day (00:00 am) was compared with the cumulative value for each direction, but the day was divided into a plurality of time zones, and the frequency of passenger occurrence by direction was calculated for each time zone. The comparison may be performed, or the comparison may be performed using an average value for the past several days.
In short, if it is possible to determine which direction the passenger is less likely to be generated in, the direction may be used as the passenger generation frequency for each direction.

In addition, in the above embodiment, a hall call in which the duration of the hall call exceeds a predetermined value (60 seconds) is detected as a long waiting call, and an empty car for rescuing the call is urgently needed. Is output, but the condition for the empty car request is not limited to this. For example, when detecting a floor where frequent passage or unloading is frequently detected during traffic congestion, when driving to avoid sharing with other people as much as possible, or in a dedicated hall to drive exclusively for guests Any time, such as when a call is registered, when a wheelchair-specific hall call is registered, or an empty car is required.

<Second Embodiment> The first embodiment is an effective method when a hall call is not registered at the floor where the final car call stops, but is assigned to another elevator car at the stop floor. If there is a hall call that has been stopped, consider that there is a high possibility that the passenger who registered the hall call has a high possibility of getting into the final car call stop car, as in the second embodiment shown below. It is better to set the designated direction S [ADV].

FIG. 7 is a flowchart showing a stop direction designation program of the elevator control apparatus according to the second embodiment of the present invention, and is a flowchart of an arithmetic program for the fifth floor of the first car. The arithmetic programs of the other floors and the second unit are similarly configured. In the second embodiment, FIGS. 1 and 3 to 5 of the first embodiment are used as they are, except for FIG. 2 (corresponding to FIG. 7) of the first embodiment.

In FIG. 7, in a step S71, it is determined whether or not an up call or a down call is registered on the fifth floor. If no ascending or descending hall call is registered on the fifth floor, steps S72 to S74 are performed.
In the same manner as in the first embodiment, the passenger occurrence frequencies N5u and N5 for each direction
By comparing d, the direction in which the frequency of occurrence of passengers is lower is set as the stop designation direction S [5].

On the other hand, if the ascending or descending hall call is registered on the fifth floor in step S71, it is determined in step S75 whether both the ascending and descending calls are registered on the fifth floor. If both the up call and the down call are registered, if both the up call and the down call on the fifth floor are assigned to the elevator car other than the first car in step S76, the number of passengers is as small as possible. Steps S72 to S7 to stop in the direction
In the same manner as in the first embodiment, the direction-specific passenger occurrence frequencies N5u and N5
By comparing 5d, the direction in which the frequency of passenger occurrence is lower is set as the stop designation direction S [5].

In step S75, if only the up call or the down call is registered on the fifth floor, and even if both the up call and the down call are registered, step S 75
If both the up call and the down call are assigned to the first car at 76, the process goes to step S77, where the up call is registered on the 5th floor and is assigned to an elevator car other than the first car. If yes, step S
At 78, the stop designation direction S [5] is set to “down”. If a down call is registered on the fifth floor in step S79 and is assigned to an elevator car other than the first car, the stop designation direction S [5] is set to "up" in step S80. Thus, in steps S77 to S80, the stop designation direction S is reversed in the direction opposite to the hall call assigned to the elevator car other than the first car.
Set as [5].

As described above, the elevator control apparatus according to the present embodiment includes the same group management unit 10, the car control units 11 and 12 for the first and second units, and the empty car request unit 10C as in the first embodiment. And a diagram in which, when there is a hall call assigned to another elevator car at a stop floor of the elevator car, a direction opposite to the direction of the hall call is designated as a direction to be stopped, 7, when an empty car request command is issued from the empty car requesting means 10C to the elevator car for stopping the final car call, the stop direction specifying means 10D Uphole lantern B1u ~
B7u or the display of the down hall lanterns B2d to B8d is controlled, and when the empty car request command is not issued from the empty car request unit 10C, the up hall lanterns B1u to B7 regardless of the designation by the stop direction designating unit 10D.
hall display control means 11C for controlling the display of u or the down hall lanterns B2d to B8d.

When an empty car request command is issued from the empty car request means 10C to the elevator car that stops the final car call, a landing call assigned to another elevator car is placed on the stop floor of the elevator car. If there is, a direction opposite to the direction of the hall call is designated as the direction to be stopped by the stop direction designating means 10D, and the up hall lantern B1 is designated.
u to B7u or the down hall lanterns B2d to B8d are displayed, and when no empty car request command is issued from the empty car request means 10C, the up hall lanterns B1u to B7u regardless of the designation by the stop direction designating means 10D.
Alternatively, the down hall lanterns B2d to B8d are displayed.

Therefore, in this embodiment, when the elevator car stops in response to the last car call, and when no empty car request command is issued, the hall except for the terminal floor has a hall in the same direction as the traveling direction. The lantern is operated and stopped, but when an empty car request command is issued, if there is a hall call assigned to another elevator car on the floor to be stopped, the direction of the hall call is reversed. The stop designation direction S [ADV] is set as the direction to stop,
Activate the hall lantern and stop. For this reason, similarly to the first embodiment, the possibility that a passenger who has entered the elevator hall after the arrival display has started is less likely to get into the elevator car in the final car call stopped state, and the empty car request command is accordingly received Elevator car can be quickly emptied. As a result, when an empty car is required, the elevator car is displayed at the stop floor of the elevator car by displaying the hall as a direction to stop in a direction opposite to the direction of the hall call assigned to the other elevator car, so that the elevator car can be stopped. As a result, the elevator car in the final car call stop state can be brought to the empty car state as soon as possible, and when no empty car is required, a landing display with high serviceability for waiting customers on the stop floor can be provided. Therefore, the service for the waiting customers is improved.

In the first and second embodiments, the hall lantern is normally turned off, and when the elevator car arrives in response to the car call, the arrival notification and the service direction guide are sent to the waiting passenger. Has been described for a group control elevator provided with an arrival indicator provided to a car position floor (generally, a synchronous car position floor SYN).
The present invention can also be applied to a group management elevator provided with a landing indicator provided with a car position indicator for displaying a car position indicator and a direction light for displaying the operation direction of the elevator car.

In this case, usually, each floor in the same direction as the traveling direction RDR is used until a predetermined period (generally, when the preceding car position floor ADV and the synchronous car position floor SYN coincide) after the elevator car starts running and after the stop is determined. When the stop light is turned on, the stop light is turned on at each floor in the same direction as the operation direction SDR during the period from the predetermined time after the stop decision to the stop and during the stop, but the empty car request command is issued To stop at the last car call, determine the operation direction according to the designated stop direction S [ADV], turn on the landing direction light in that direction, and stop at the last car call when no empty car request command is issued. In this case, the landing direction light is turned on in a direction determined irrespective of the stop designation direction S [ADV] (for example, the same direction as the direction RDR in which the vehicle has traveled so far). When the direction of the elevator car is reversed, the landing direction light is switched at the predetermined time.

Even when the hall direction lights are provided in this manner, the waiting passengers will see the hall direction lights of the elevator car to which the empty car request command has been issued while the door is open, and immediately enter the car. However, the present invention makes it possible to quickly bring the last car with the empty car request command to the empty car state by using the present invention.

In each of the above embodiments, the case where two elevator cars are provided is shown, but the present invention can be applied to three or more group control elevators.
