Description

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 in particular, each landing indicator such as an arrival indicator (hall lantern, chime) or a direction indicator (direction light) provided in an elevator hall. The present invention relates to an elevator control device for controlling the operation of the.

[0002]

2. Description of the Related Art Conventionally, arrival of an elevator car is notified to a waiting passenger at an elevator hall by an arrival display.
Regarding this arrival display, as described in Japanese Patent Publication No. 63-17746, a hall lantern and an arrival chime are usually provided at the landing of each elevator car, and it is decided to stop the elevator car and start the door opening. Five seconds ago, the hall lantern blinks and the arrival chime rings in a continuous tone. When the passengers have finished getting on and off and the door is about to be closed, the hall lantern stops blinking and goes out. Since the waiting passengers can prepare to board the elevator car according to the state of the arrival display, the passenger does not become aware of the arrival of the elevator car and is not injured or delayed. Further, such arrival display allows the passengers to get on and off the elevator car promptly and prevent a decrease in the operating efficiency of the elevator.

In addition, a car position indicator and a direction indicator (direction light) are provided at the elevator hall to display the present car position and the traveling direction to waiting passengers at the elevator hall. The display of both the car position and the direction of travel allows the waiting passenger to have an idea of how long to wait for the elevator car to arrive in the desired direction, and prepares to get into the elevator car accordingly.

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

That is, since the elevator car in the final car call stop state usually waits on that floor, it is considered that it is not necessary to display either direction, but then the following problems occur. obtain. For example, when a passenger who wants to use the elevator car enters the elevator hall when the last passenger gets off after opening the door, it is confusing because the direction in which the elevator car is operated is unknown. Also, if passengers who want to go to the opposite floors get on at almost the same time, the direction of operation of the elevator car will be decided as soon as possible by the direction desired by the customer who pressed the destination button in the car. The customer who presses the car will continue to ride until it gets off immediately or endures the operation in the opposite direction, and then presses the destination button on the floor where he / she wants to go.

Therefore, in a system in which a hall lantern or a direction light is provided in an elevator hall to display the traveling direction, it is usual to display a predetermined direction corresponding to each floor. Normally, the floors below it, including the first floor, show the up direction, the top floor shows the down direction, and the other floors show the same direction as the elevator had been moving until then (hereinafter called the traveling direction). It is supposed to do.

However, in the above display, when the elevator car arrives in response to the final car call, a hall call in the direction opposite to the direction desired by the waiting passengers may be registered. For example, if you stop in the up direction by calling the last car on the 5th floor, you will be notified of the arrival by blinking the hall lantern in the up direction from 4 seconds before the door starts to open. It is assumed that a customer who goes to the floor enters the elevator hall on the 5th floor, presses the hall button, and registers a hall call in the down direction. In this case, after a predetermined door opening time has passed, the elevator car temporarily closes the door and after confirming that there is no call to the floors above the fifth floor, the elevator car switches to the downward direction and opens again. , Double door operation. The reason for not reversing the direction with the door open is to prevent passengers going upstairs who may be in the elevator car from switching to the down direction before pressing the destination button. .. Further, once the door is closed, it is possible to secure the time for pressing the destination button during the door close operation, and it is possible to prevent new passengers (especially passengers going in the opposite direction) from getting in. is there.

However, this double-door operation looks very unnatural to the passengers going to the first floor. That is, while waiting passengers at the elevator hall can see at a glance whether there are passengers in the car, they feel suspicious as to why the door closing operation should be performed when there are no people in the car.

Therefore, in order to reduce the chances of occurrence of the double door operation described above, as shown in Japanese Patent Laid-Open No. 128288/1993, the direction in which the waiting passengers on the floor to stop has a high probability is directed. Learning each,
Lighting of hall lanterns and direction lights in that direction is performed.

On the other hand, service status (waiting time) and type (calls for wheelchairs, calls for guests, etc.) for hall calls
Depending on the call, you can quickly empty the elevator car that is currently in service (make it an elevator car that is closed without waiting for a call to answer) and rescue long-waiting calls or calls that have been packed. , There are times when you want to make a dedicated call respond quickly. In such a case, conventionally, a method of limiting the allocation of new hall calls to the elevator car to be emptied is adopted.

[0011]

However, in the conventional elevator control device as described above, even when it is desired to quickly bring the elevator car to the empty car state, the elevator hall of the elevator car whose door is open after the final car call is stopped. Occasionally, a customer came in in the same direction as the direction of operation, checked the hall lantern and direction lights, and boarded the elevator car with the door open. In this case, the newly registered car call must be answered, so that the elevator car was delayed by that much. In particular, when the final car call is stopped, in order to reduce the chances of double door operation, the elevator car is stopped by turning on the hall lanterns and direction lights in the direction in which there is a high probability of waiting passengers on the stopping floor. In this case, although it was desired to quickly put the elevator car into an empty car state, it could not be easily made into an empty car.

Therefore, an object of the present invention is to provide an elevator control device that can quickly bring an elevator car whose final car call has stopped to an empty car state when an empty car is required.

[0013]

An elevator control apparatus according to a first aspect of the present invention is a group for performing group management by allocating a plurality of elevator cars according to a hall call registration by a hall button arranged on each floor. The elevator car responds to the car allocation and car call registration of the management means and the group management means, performs each control necessary for the operation of the elevator car, and displays the operation direction on the hall display. Car control means, empty car request means for issuing an empty car request command that requires an empty car that is in a closed state without call registration to respond in response to the operation status of each elevator car, and responds to the call registration Then, when the elevator car is stopped, there is no other call to respond to in the front of the traveling direction of the elevator car, and the elevator car stops only in response to car call registration on the stop floor. And the final car call stop determining means constant for,
The empty car request means for the empty car request means for the elevator car stopping the final car call by detecting the direction in which passengers are rarely generated by direction at the stop floor of the elevator car When a command is issued,
The display of the hall indicator is controlled according to the designation by the stop direction designating means, and when the empty car request command is not issued from the empty car requesting means, the hall display is independent of the specification by the stopping direction designating means. And a hall display control means for controlling the display.

According to a second aspect of the present invention, there is provided an elevator control device, which includes group management means for managing a group by allocating a plurality of elevator cars according to a hall call registration by a hall button provided on each floor, and the group. In response to the car allocation and car internal call registration of the management means, the elevator car is made to respond, and each control necessary for the operation of the elevator car is performed, and the car control means for guiding and displaying the operation direction on the hall display, An empty car request means that issues an empty car request command that requires an empty car that is in a closed state without call registration to respond depending on the operation status of each elevator car, and the elevator car stops in response to the call registration When there is no other call to respond to in the front of the traveling direction of the elevator car and the car stops on the floor only responding to call registration, the final car is judged to be the final car. Stop determination means, when there is a hall call assigned to another elevator car on the stop floor of the elevator car, a stop direction designating means for designating a direction opposite to the direction of the hall call as the direction to stop, With respect to the elevator car that stops the final car call, when an empty car request command is issued from the empty car request means, the display of the hall indicator is controlled according to the specification by the stop direction specification means, When the empty car request command is not issued from the empty car request means, there is provided a hall display control means for controlling the display of the hall indicator regardless of the designation by the stop direction designating means.

[0015]

According to the elevator control apparatus of the invention of claim 1, an empty car for issuing an empty car request command to the elevator car for which the final car call is stopped and which requires an empty car which is in a closed state without call registration. When an empty car request command is issued from the requesting means, a display on the hall indicator is displayed in accordance with the designation by the stop direction designating means which detects and designates the direction in which the frequency of occurrence of passengers by direction at the stop floor of the elevator car is low in advance. When the empty car request command is not issued from the empty car requesting means, the empty car is required because the display of the hall indicator is controlled regardless of the designation by the stop direction designating means. In order to prevent passengers from entering the elevator car on the floor where the probability of waiting is low, the passengers will be restrained from entering the elevator car as much as possible. The hall display with high service with respect to the floor of the waiting customers.

In the elevator control apparatus according to the second aspect of the present invention, an empty car in a door-closed state without a call registration to respond to the elevator car for which the final car call is stopped depending on the operation status of each elevator car. When an empty car request command is issued from the empty car request means that issues an empty car request command, when there is a hall call assigned to another elevator car on the stop floor of the elevator car, that hall call When the empty car request command is not issued from the empty car request means, the display of the hall indicator is controlled according to the designation by the stop direction designating means that designates the direction opposite to the direction as the direction to stop. Since the display of the hall indicator is controlled regardless of the designation by the stop direction designating means, when an empty car is required, another elevator is installed on the stop floor of the elevator car. The direction opposite to the direction of the hall call assigned to the car is displayed as the direction to stop, the passenger's entry into the elevator car is suppressed as much as possible, and when the empty car is not needed, the stop floor A hall display with high serviceability for waiting passengers is displayed.

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

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

In FIG. 2, steps S101 to S108 are calculation programs for the first to eighth floors, respectively, and the number of hall call generations on each floor is accumulated in each direction, and these sizes are compared to stop. Direction S [1] to S
Set [8] respectively. This setting operation of the direction to be stopped will be described with reference to the calculation program for the fifth floor (step S105). The calculation programs for other floors other than the fifth floor operate in the same manner.

When the beginning of the day (00:00 am) is detected in step S111, both the upward call counter N5u and the downward call counter N5d are set to "0" in step S112.
Reset to. After that, the direction to be stopped is set in steps S113 to S119.

When it is detected in step S113 that the 5th floor upstream call has just been registered, step S114 is performed.
The up call counter N5u is incremented by "1". When it is detected in step S115 that the downlink call for the fifth floor has just been registered, the downlink call counter N5d is incremented by "1" in step S116. Then, in step S117, it is determined whether N5d ≧ N5u, and N5d ≧ N5u.
In the case of 5u, the designated stop 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.

With this series of operations, the stop decision designating program obtains the number of hall calls generated by each floor on each floor,
The direction in which this is smaller is set as the direction to stop.

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

In FIG. 3, in step S21, it is judged whether or not immediately after the stop decision is made by the 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 set at the same time as setting the operation direction of the elevator car when the stop is determined. That is, immediately after the stop decision, 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 according to the current traveling speed) ) Determines whether there is a hall call (allocated hall call) to respond in the same direction as the traveling direction RDR. If there is the above 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 represents the direction in which the elevator car is moving from the start to the stop, and after the stop, it is moving before stopping until it starts again. This is data representing the direction in which

On the other hand, if there is no hall call corresponding to the above in step S22, the process proceeds to step S23, and the floor ahead of the preceding car position floor ADV (upward if the traveling direction SDR is up, down if the traveling direction SDR is down). It is determined whether there is a landing call or a car call to respond to. If there is a landing 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, and the front floor is set. If there is no call to answer, go to step S25,
It is determined whether or not the preceding car position floor ADV has a hall call to respond in a direction opposite to the traveling direction RDR. If there is the corresponding landing call, the operation direction SDR is set to the reverse direction of the traveling direction RDR in step S26. If there is no such landing call, the process proceeds to step S27, where the preceding car position floor ADV is the highest. Determine whether it is the lower floor or the top floor.
If it is the lowest floor or the highest 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 lowest floor nor the highest floor, the operation direction SDR is determined in step S28. Is set to the same direction as the traveling direction RDR, and "final car call stop" is detected.

Through the series of operations described above, the final car call stop determination program sets the driving direction SDR of the elevator car immediately after the stop decision, and determines whether or not it is "final car call stop".

Next, the traveling direction control program shown in FIG. 4 will be described.

In FIG. 4, in step S31, it is determined whether the elevator car is decelerating (the period from the stop decision to the stop) and "the final car call is stopped", and the arrival display operation is performed in step S32. Judge whether it is before or not. If the vehicle is decelerating and "last car call is stopped" and is in a state before the arrival display, the response generated from the stop decision to the arrival display is performed by a series of operations from step S33 to step S40. Change the direction of operation depending on whether there is a power call or an empty car request command.

Steps S33 and S34 are shown in FIG.
Is exactly the same as the detection conditions in steps S22 and S23 in step S22, and whether or not the preceding car position floor ADV has a landing call in the same direction as the traveling direction RDR and the front of the preceding car position floor ADV (the traveling direction SDR It is determined whether or not there is a hall call (allocated hall call) or a car call to be answered on the upper floor if is an uphill floor or if it is a downhill floor.
If there is a call corresponding to any of the above, step S3
In step 5, the traveling 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 of 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 (allocated hall call) to be answered in the opposite direction to DR. If there is the corresponding landing call, the operation direction SDR is set to the opposite direction of the traveling direction RDR in step S37, and if there is no such landing call, is there an empty car request command 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 (assigned hall call) to be answered on the floor behind the preceding car position floor ADV. If there is a hall call on the back floor that should be answered, step S
At 37, the operating direction SDR is set to the opposite direction of the traveling direction RDR, and when there is no landing call to respond on the rear floor, the operating direction SDR set immediately after the stop decision is held.

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

By this series of operations, in the operation direction control program, when "final car call stop", the call to be responded after the stop decision 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 by direction. In addition,
The time during which the operation direction SDR can be freely set is not only during the predetermined period after the stop is determined but also at the time when the door is completely closed and in the non-direction state. In either 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 may be set to be non-direction or may be set to a direction for a call to be newly answered, but since these operations are well known and are not directly related to the present invention, detailed description thereof will be given here. The description is omitted.

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

In FIG. 5, in step S51, it is determined whether the elevator car of the first car starts the arrival display and is in the arrival display. Immediately after the elevator car is determined to stop, the arrival display (blinking of the hall lantern) has not started yet, so the process proceeds from step S51 to step S52 where the elevator car starts T seconds before door opening (for example,
It is determined whether the position is within 4 seconds). If the position is not within T seconds before the door is opened, the arrival display is not started, but if the position is within T seconds before the door is opened,
In step S53, the hall lantern in the direction corresponding to the traveling direction SDR set at this point 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 continues to blink until it is detected in step S54 that the door is about to be closed. Immediately before the door is closed, the hall lantern is turned off and the determination of "final car call stop" is reset in step S55.

By such a series of operations, in the hall display control program, the up hall lanterns B1u to B7u on the 1st to 7th floors and the down hall lanterns B2d to B8d on the 2nd to 8th floors are turned on and arrive according to the operation direction SDR. Controls the ringing of a chime (not shown).

Here, the operation of this embodiment will be described based on a concrete 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 8th floor is determined to stop in response to a car call on the 5th floor. And Further, at this point, the value of the upward call counter N5u on the fifth floor is 56, and the value of the downward call counter N5d is 3.
It is assumed that there are 21 and the designated stop direction S [5] is set to "up."

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 call to be answered by the time just before the arrival display is started, the operation direction SDR is "up" according to the stop specified direction S [5] (= "up") set by the stop direction specification program. Changed,
The hall display lantern B5u is blinked by the hall display control program to guide and display the arrival and service directions of the elevator car at the hall.

Normally, the No. 1 vehicle is stopped in the "down" direction which is the same direction as the traveling direction RDR, and the hall lantern B5d in the down direction is blinked to guide the arrival service direction to the elevator hall. When the empty car request command is issued, the hall lantern B5u in the upward direction in which passengers are unlikely to occur is operated and stopped, so that the first car is likely to be in an empty car state on the fifth floor. Moreover, since no landing call is newly assigned to the 1st car for which an empty car request command is issued even if a downcall is registered on the 5th floor,
There is no need to worry about double door operation in response to this downward call.

As described above, the elevator control device of this embodiment serves a plurality of floors from the first floor to the eighth floor.
No. 2 and No. 2 elevator cars 1a, 2a, hall buttons A1 to A8 arranged on each floor for calling up the elevator cars, and hall buttons A1 to A8 are registered when the hall buttons A1 to A8 are operated.

Alternatively, 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 means 10C, the up hall lanterns B1u to B7u or regardless of the designation by the stop direction designating means 10D. It is provided with a hall display control means 11C for controlling the display of the down hall lanterns B2d to B8d.

When an empty car request command is issued from the empty car requesting means 10C to the elevator car for which the final car call is to be stopped, at the elevator car stop floor specified by the stop direction specifying means 10D. The up hall lanterns B1u to B7u or the down hall lanterns B2d to B8d in the direction in which passengers are not frequently generated are displayed, and when the empty car request command is not issued from the empty car request means 10C, the stop direction is designated. The up hall lanterns B1u to B7u or the down hall lanterns B2d to B8d are displayed regardless of the designation by the means 10D.

Therefore, in this embodiment, when the elevator car stops in response to the final car call, when no empty car request command is issued, on the floors other than the terminal floor,
Stop by operating the hall lantern in the same direction as the traveling direction, but when an empty car request command is issued, stop by operating the hall lantern in the direction in which the frequency of passenger occurrence by direction is low on the floor to stop. To do. Therefore, the possibility that passengers who enter the elevator hall after the arrival display starts will get on the elevator car in the final car call stop state, and the elevator car that received the empty car request command will be moved to the empty car state as soon as possible. can do. As a result, when an empty car is needed, by displaying the landing in the direction in which the waiting passengers on the floor to stop are less likely to go, it is possible to suppress the passengers getting into the elevator car as much as possible, so the final car call stop You can quickly put the elevator car into the empty car state,
When an empty car is not needed, a hall display with high serviceability for waiting passengers on the stop floor can be displayed, so that the service for waiting customers is improved.

By the way, in the above-mentioned embodiment, when it is detected that there is no call ahead of the preceding car position floor in the traveling direction and that the call is stopped only in response to the car call at the preceding car position floor, the preceding car position floor is detected. It is determined to be "final car call stop" (step S28 in FIG. 3) regardless of whether or not there is a landing call to be answered on the floor behind. When there is a landing call to be answered behind the preceding car position floor, it is possible to set the operation direction to the direction opposite to the running direction and stop without calling it as "final car call stop". When the vehicle is turned over and stopped, passengers in the opposite direction of travel are more likely to get on the floor, and passengers in the opposite direction are more likely to get on the floor. I'll be late. Therefore, in the above embodiment, even when there is a hall call to be answered on the floor behind the preceding car position floor,
By determining "final car call stop", if the empty car request command is issued, the hall lantern in the direction in which the frequency of occurrence of passengers by direction is low can be stopped by blinking. Of course, when there is a landing call to be answered on the floor behind the preceding car position floor, even if the operation direction is set to the direction opposite to the traveling direction and it is not judged as "final car call stop", The effect can be fully obtained.

In the above embodiment, the time to start the arrival display is T seconds (4 seconds) before the door starts, but the way to set the time to start the arrival display is not limited to this. .. For example, the above setting time may be changed according to the arrangement and number of each elevator car, or each of the elevator cars may be set according to the distance to the stop position, and various other methods are possible.

In the above embodiment, when the empty car request command is not issued, the hall lantern in the same direction as the traveling direction is operated to stop the elevator car on the floors other than the terminal floor. The method of deciding 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 direction-specific passenger occurrence frequency is higher on the floor to be stopped may be operated and stopped. In this case, it is possible to reduce the occurrence of double door operation when a hall call to be answered in a direction opposite to the operation direction occurs on the floor where the car is located.

Further, in the above embodiment, the number of upward calls and downward calls generated for each floor is calculated as a cumulative value from the beginning of the day,
Although this is treated as the passenger occurrence frequency by direction, the possibility of passengers getting in by direction is not limited to this. For example, it is possible to detect the change in the output of the weighing device provided on the car floor and obtain the weights of passengers and alighting passengers for each floor by service direction, and use this as the passenger occurrence frequency for each direction. A sensor for detecting the number of passengers getting on and off may be installed above the entrance of the car to obtain the number of passengers for each floor by service direction. We also compared the cumulative number of hall calls from the beginning of the day (midnight) by direction, but divided the day into multiple time zones and calculated the passenger occurrence frequency by direction for each time zone. The comparison may be performed by using the average value of the past several days.
In short, as long as it is possible to determine which of the upper and lower directions passengers are unlikely to occur, what may be used as the direction-specific passenger occurrence frequency.

In addition to the above, in the above-described embodiment, a hall call whose duration of the hall call exceeds a predetermined value (60 seconds) is detected as a long-waiting call, and an empty car is needed immediately to rescue this call. Although the empty car request command indicating that is output is output, the condition for empty car request is not limited to this. For example, when you detect a floor that is often overcrowded or unfilled during traffic congestion, when driving to avoid riding with other people as much as possible, or when you are driving exclusively for a guest Any condition may be used, such as when a call is registered, when a wheelchair-only landing call is registered, or when an empty car is required.

<Second Embodiment> In the first embodiment, the method is effective when the landing call is not registered on the floor to be stopped by the final car call, but it is assigned to another elevator car on the floor to be stopped. If there is a landing call that has been stopped, the passenger who registered the above landing call is stopped in consideration of the high possibility of getting into the final car stop car, as in the second embodiment shown below. It is better to set the designated direction S [ADV].

FIG. 7 is a flow chart showing a stop direction designating program of the elevator control apparatus according to the second embodiment of the present invention, and is a flow chart of the arithmetic program for the fifth floor of the first car. The calculation programs of the other floors and the second car are also configured in the same manner. In this second embodiment, except for FIG. 2 (corresponding to FIG. 7) of the first embodiment, FIGS. 1 and 3 to 5 of the first embodiment are used as they are.

In FIG. 7, in step S71, it is determined whether an up call or a down call is registered on the 5th floor. If no landing call for an up call or a down call is registered on the 5th floor, steps S72 to S74.
In the same manner as in the first embodiment, the direction-dependent passenger occurrence frequencies N5u and N5
d is compared, and the direction with the lower passenger occurrence frequency is set as the stop designation direction S [5].

On the other hand, when the landing call of the up call or the down call is registered in the fifth floor in step S71, it is determined in step S75 whether both the up call and the down call are registered in 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 5th floor are assigned to elevator cars other than the first car in step S76, the number of passengers is as small as possible. Step S72 to Step S7 to stop in the direction
In the same manner as in the first embodiment, the passenger occurrence frequencies N5u and N
5d are compared, and the direction in which the passenger occurrence frequency is low is set as the stop designation direction S [5].

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

As described above, the elevator control apparatus of this embodiment has the same group management unit 10 as the first embodiment, the car control units 11 and 12 for the first and second cars, and the empty car requesting means 10C. And a final car call stop determination means 11E, and when there is a hall call assigned to another elevator car on the stop floor of the elevator car, the direction opposite to the direction of the hall call is designated as the direction to stop. When the empty car requesting command is issued from the empty car requesting device 10C to the stopping direction specifying device 10D for performing the operation 7 and the elevator car for stopping the final car call, the stopping direction specifying device 10D is used. Up hall lantern B1u ~
When the display of B7u or the down hall lanterns B2d to B8d is controlled and no empty car request command is issued from the empty car request means 10C, the up hall lanterns B1u to B7 are irrespective of the designation by the stop direction designating means 10D.
The hall display control means 11C for controlling the display of u or the down hall lanterns B2d to B8d.

When an empty car requesting command is issued from the empty car requesting means 10C to the elevator car for which the final car call is stopped, the hall call assigned to another elevator car on the stop floor of the elevator car. If there is, the up hall lantern B1 is designated by the stop direction designating means 10D as the direction opposite to the direction of the hall call to be the direction to stop.
u to B7u or 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 are irrespective of the designation by the stop direction designating means 10D.
Alternatively, the down hall lanterns B2d to B8d are displayed.

Therefore, in the present embodiment, when the elevator car stops in response to the final car call, when the empty car request command is not issued, the halls in the same direction as the traveling direction are used on the floors other than the terminal floor. The lantern is operated to stop, but when an empty car request command is issued, if there is a hall call assigned to another elevator car on the floor to stop, the direction opposite to that of the hall call Set the designated stop direction S [ADV] as the direction to stop,
Activate the hall lantern and stop it. Therefore, as in the case of the first embodiment described above, the possibility that passengers entering the elevator hall after the start of the arrival display will board the elevator car in the final car call stop state is reduced, and the empty car request command is received accordingly. The elevator car can be emptied quickly. As a result, when an empty car is needed, the elevator car is displayed on the stop floor of the elevator car by displaying the hall as the direction to stop in the direction opposite to the direction of the hall call assigned to another elevator car. As the number of passengers in the car can be suppressed as much as possible, the elevator car in the final car stop state can be quickly moved to an empty car state, and when there is no need for an empty car, a hall display with high serviceability for waiting passengers on the stop floor can be displayed. Therefore, the service for 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 a car call, the arrival notification and service direction guidance are given to the waiting passengers. I explained about the case of applying to the group control elevator equipped with the arrival indicator for the car position floor (generally the synchronous car position floor SYN.
It is also applicable to a group control elevator provided with a landing indicator provided with a car position indicator for displaying () is used) and a direction light for displaying the traveling direction of the elevator car.

In this case, normally, each floor in the same direction as the traveling direction RDR from the start of the traveling of the elevator car to the predetermined period after the stop decision (generally, the point where the preceding car position floor ADV coincides with the synchronous car position floor SYN). When the stop car is ordered to turn on, the stop lights for each floor in the same direction as the operation direction SDR are turned on during the period from the predetermined time after the stop decision to the stop and during the stop. If you want to stop at the last car call, determine the operating direction according to the specified 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 lights are turned on in a direction (for example, the same direction as the direction RDR in which the vehicle has traveled up to that time) determined irrespective of the designated stop direction S [ADV]. When the direction of the elevator car is reversed, the landing direction lights are switched at the predetermined time.

Even when the landing direction lights are provided in this way, the waiting passengers see the landing direction lights of the elevator car for which the empty car request command is issued while the door is open, and board the car as it is, and the final car call stop car However, by using the present invention, it is possible to quickly bring the final car call-stopped car for which the empty car request command is issued to the empty car state.

In each of the above embodiments, the case where two elevator cars are provided has been shown, but it is naturally applicable to three or more group management elevators.

[0067]

As described above, the elevator control apparatus according to the first aspect of the present invention includes a group management means, a car control means, an empty car request means, a final car call stop determination means, and a stop direction designating means. And the elevator display control means, and for the elevator car that makes the final car call stop, the empty car request means that issues an empty car request command that requires an empty car that is in a closed state without call registration When the request command is issued, the display of the hall indicator is controlled according to the designation by the stop direction designating unit which detects and designates the direction in which the frequency of passenger occurrence by direction at the stop floor of the elevator car is low in advance, When an empty car request command is not issued from the empty car requesting means, by controlling the display of the hall indicator regardless of the designation by the stop direction designating means, when the empty car is needed, the floor to be stopped is displayed. By displaying the landing in the direction in which the waiting passengers are less likely to go and restraining passengers from getting into the elevator car as much as possible, it is possible to quickly put the elevator car that stopped the last car into an empty car state and require an empty car If this is not the case, a hall display with a high serviceability for waiting passengers on the stop floor can be displayed, so the service for waiting customers is improved.

The elevator control apparatus according to the invention of claim 2 is

However, in the above display, when the elevator car arrives in response to the final car call, it is displayed.
A landing call in the opposite direction to the specified operating direction may be registered. For example, if you stop in the up direction by calling the last car on the 5th floor, you will be notified of the arrival by blinking the hall lantern in the up direction from 4 seconds before the door starts to open. It is assumed that a customer who goes to the floor enters the elevator hall on the 5th floor, presses the hall button, and registers a hall call in the down direction. In this case, after a predetermined door opening time has passed, the elevator car temporarily closes the door and after confirming that there is no call to the floors above the fifth floor, the elevator car switches to the downward direction and opens again. , Double door operation. The reason for not reversing the direction with the door open is to prevent passengers going upstairs who may be in the elevator car from switching to the down direction before pressing the destination button. .. In addition, once the door is closed, it is possible to secure the time to press the destination button during the door close operation, and it is possible to prevent new passengers (especially passengers going in the opposite direction) from getting in. is there.
