Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator group management system, and more particularly to an elevator group management system for collectively controlling a large number of elevator cars arranged side by side.

[0002]

2. Description of the Related Art Conventionally, a large number of high-rise and large-scale buildings have been constructed in response to the demand for building construction, and a large number of elevator cars are installed in these buildings as the resident population increases. Considering the ease of riding passengers, the maximum number of ordinary elevator cars is limited to about 4 or 5, but in the above-mentioned high-rise and large-scale buildings, due to the layout inside the building, etc.
In some cases, there is no choice but to arrange eight or eight units side by side.

Therefore, for example, even if the hall button of the elevator car installed at one end is operated by the waiting passengers and the elevator car on the other side arrives at the floor of the waiting passengers in response to the call, the elevator car will be appointed. There is a possibility that the passengers will miss the arrival of the car and may miss the car, and the service for the passengers will not be taken into consideration.

Therefore, for example, Japanese Laid-Open Patent Publication No. 61-29138.
There is an elevator group management apparatus that delays the opening time of a door by tracking the behavior of a waiting customer like the technology disclosed in Japanese Patent Publication No. 6.

[0005]

Since the conventional group management device for the elevator is configured to simply delay the opening time of the door as described above, waiting passengers may not arrive at the elevator car during the delay time. There is no guarantee that you will notice. Therefore, there is a possibility that the waiting passengers may not notice the arrival of the elevator car and may miss the train. on the other hand,
As other prior art, JP-A-62-51589,
Japanese Unexamined Patent Publication No. 1-288581 and Japanese Utility Model Laid-Open No. 1-257567
There is a bulletin, etc. First, in Japanese Patent Laid-Open No. 62-51589, a first detection switch for detecting a wheelchair on the floor surface of a car and a second detection switch provided for detecting a wheelchair on the floor surface of each elevator hall, Wheelchair door opening / closing control device for controlling the first and second detection switches so that, when one of the detection switches is activated, the open state of the car and the hall door is continued until the other detection switch is activated. And a technology that enables general customers and wheelchair users to comfortably and safely use the elevator. However, when the general customers and wheelchair users wait for the elevator car and are careful about their arrival, the operation is suitable, but when the general customers and wheelchair users overlook the arrival of the elevator car, ,
It becomes a factor that reduces the operation efficiency. In addition, JP-A 1-2
JP-A-88581 discloses that when a call is generated, when an elevator car is assigned to the call, a lantern is lit and a chime is struck to make a reservation display, a standby command is issued to the elevator car, and a lantern flicker and a chime after a predetermined time. There is disclosed a technique of delaying the door opening start time by hitting twice to display an arrival forecast and outputting a door opening command. However, even if the arrival is unilaterally displayed by the lantern and the chime from the elevator, the reaction of the general customer cannot be detected on the elevator side and used for controlling the elevator. And, in Japanese Utility Model Publication No. 1-257567,
If the cargo handling is completed within the predetermined time, the door closing operation is automatically performed.If the cargo handling is not completed within the predetermined time, the door closing operation is blocked until the cargo handling is completed, and the elevator is closed. A technique is disclosed that can secure a door opening time required for cargo handling without hindering operation. However, during the cargo handling work, although the worker recognizes the opening and closing of the door, when the elevator car arrives, the worker may overlook the arrival of the elevator car.

Therefore, the present invention promptly notices that an elevator car arrives with high reliability regardless of the waiting position of the waiting passengers on the floor even when a large number of elevator cars are installed in parallel. It is an object of the present invention to provide an elevator group management device that can be turned on.

[0007]

According to a first aspect of the present invention, there is provided an elevator group management device for responding to a call operation of a waiting customer, wherein one of a plurality of elevator cars is driven to a floor of the waiting customer. And, a waiting position detecting means for detecting the position of the waiting passenger waiting at the hall, and a chime ringing when the elevator car arrives at the floor of the waiting passenger by the car control means,
Although the elevator car has opened the door and a predetermined time has elapsed, a passenger of the waiting passenger cannot be detected, and the distance between the waiting passenger and the elevator car detected by the waiting passenger position detecting means is a predetermined value. In the above case, the chime control means for re-ringing the chime is provided.

[0008]

According to the first aspect of the present invention, the distance between the elevator car and the waiting passengers is equal to or greater than the predetermined value in spite of the fact that the elevator car arrives at the floor and the chime rings in response to the call operation of the waiting passengers. When it is, the chime control means reactivates the chime to call the attention of the waiting customer. In addition, in response to the call operation of the waiting passengers, the waiting passengers did not board even after the elapse of a predetermined time after the door of the elevator car was opened, even though the elevator car arrived on that floor and the chime rang. Also at this time, when the distance between the waiting passenger and the elevator car detected by the waiting passenger position detecting means is equal to or more than a predetermined value, the chime control means sounds the chime again to call the attention of the waiting customer.

[0009]

Embodiments of the present invention will be described below. FIG. 2 is a perspective view showing an elevator hall of the elevator group management system according to the embodiment of the present invention.

In the figure, 1a to 1f are doors of six elevators arranged side by side, and 2a to 2c are the doors 1a to 1a.
The landing call button 3a to 3f provided on the side of f for calling up the elevator car is also the doors 1a to 1f.
A home lantern, which is provided beside the vehicle for displaying the arrival or forecast of the arrival of the elevator car, is a television camera installed on the ceiling of the elevator hall.

FIG. 1 is a block diagram showing the electrical construction of an elevator group supervisory control system according to an embodiment.

A hall control circuit for fetching the operation state of 2c and controlling the home lanterns 3a to 3f, and 7a to 7f as car control means for running each elevator car, opening and closing the doors 1a to 1f, and detecting passengers getting on and off. It is a car control circuit. Also,
8a to 8f are provided in each hall, and a chime ringing circuit that constitutes a chime control means for ringing a chime each time the elevator car arrives at the floor of a waiting passenger, 9 is a hall based on image data from the TV camera 4 It is a waiting customer position detecting circuit as a waiting customer position detecting means for detecting the position of a waiting customer.

Next, the operation of the elevator group management system of the present embodiment constructed as described above will be explained. FIG. 3 is a flow chart showing the processing of the operation control circuit 5. The operation control circuit 5 executes this flow chart when the hall call buttons 2a to 2c are operated by the waiting passenger at any of the halls.

The operation control circuit 5 registers a hall call in step S1, selects an elevator car, and causes the car control circuits 7a to 7f to travel to the floor of the waiting passenger. Next, in step S2, the waiting passenger position detection circuit 9 is caused to start detecting the position of the waiting passenger in the hall based on the image data from the television camera 4. Furthermore, when the elevator car arrives at the floor of the waiting passenger, the doors 1a to 1f are opened in step S3, and the home lanterns 3a to 3f corresponding to the arrived elevator car are opened.
Is blinked by the hall control circuits 6a to 6f, and the chime ringing circuits 8a to 8f ring the chime.

Then, in step S4, the distance between the waiting passenger detected by the waiting passenger position detecting circuit 9 and the elevator car arriving at the floor is calculated, and when the value calculated in step S5 is less than a predetermined value. , Waiter is home lantern 3a ~
It is determined that the elevator car is approaching because the 3f blinking and the chime ringing are noticed, and the process proceeds to step S6. Further, in steps S6 and S7, it is determined whether the waiting passengers have boarded the passengers within a predetermined time after opening the elevator car doors 1a to 1f. To finish. Then, the elevator cars travel to the floor desired by the passengers by the car control circuits 7a to 7f. The above is the case where the waiting passenger notices the arriving elevator car without delay.

On the other hand, if it is determined in step S5 that the distance between the waiting passenger and the elevator car is equal to or greater than the predetermined value, the waiting passenger diverts his attention to the other and does not notice the blinking of the home lanterns 3a to 3f and the ringing of the chime. The chime is sounded again in step S8. Therefore, the waiting passengers will be alerted to notice the arrival of the elevator car.

Further, the steps S6 and S7.
When a predetermined time has passed without detecting the waiting passengers,
As in the case described above, the waiting passengers receive home lanterns 3a-3.
If the user does not notice the blinking of f or the ringing of the chime, the chime is ringed again in step S8. Therefore, in this case as well, the attention of the waiting passengers is called to notice the arrival of the elevator car.

As described above, the elevator group management system of the above-described embodiment responds to a call operation of a waiting customer, and causes one of the elevator cars to travel to the floor of the waiting customer.

When the distance between the elevator car and the waiting passenger detected by the waiting passenger position detection circuit 9 is equal to or greater than a predetermined value, or when the elevator car opens the doors 1a to 1f and a predetermined time elapses. Regardless, it is provided with an operation control circuit 5 and chime ringing circuits 8a to 8f for ringing the chime when a passenger is not detected in the vehicle.

Therefore, in the above-described embodiment, the elevator car arrives at the floor in response to the call operation of the waiting passenger, and the home lanterns 3a to 3f are blinked and the chime is ringed, but the elevator car is not operated. If the distance between the passenger and the waiting passenger is a predetermined value or more, or if the passenger does not board the elevator car after the doors 1a to 1f are opened and the predetermined time has elapsed, the operation control circuit 5 causes the chime ringing circuit. The chime is sounded again at 8a to 8f, and the attention of the waiting customer is called.

As a result, for example, a customer waits at the door 1 at one end.
Even if a passenger waits in front of a and the home lantern 3f blinks when the elevator car on the opposite side arrives at that floor and the home lantern 3f blinks or the chime ringing is missed by the waiter, it is re-ring. The chime will let the waiting passengers notice the arrival of the elevator car. Therefore, even when six elevator cars are arranged side by side in a row as in this embodiment, it is possible to prevent waiting passengers from delaying passengers and to provide a caring service.

By the way, the waiting customer position detecting means of the above embodiment is constructed as a waiting customer position detecting circuit 9 for detecting the position of the waiting customer in the television camera 4. However, in the case of implementing the present invention, The present invention is not limited to this, and any device that can detect the position of a waiting passenger at the hall can be used.

The chime control means of the above embodiment is
The operation control circuit 5 for controlling the operation of the elevator car and the chime ringing circuits 8a to 8f for ringing the chime are included. However, the present invention is not limited to this, and the elevator is not limited to this. When it is presumed that the passenger does not notice the arrival of the elevator car, such as when the car and the waiting passenger are over a predetermined distance or when the passenger's boarding is not detected even when the doors 1a to 1f of the elevator car are opened. Anything that sounds a chime should do.

[0023]

As described above, the elevator group management system according to the first aspect of the invention responds to the call operation of the waiting customer and causes one of the elevator cars to travel to the floor of the waiting customer. And, a waiting position detecting means for detecting the position of the waiting passenger waiting at the hall, and a chime ringing when an elevator car arrives at the floor of the waiting passenger by the car control means, and the elevator car When the distance from the waiting passengers detected by the waiting passenger position detecting means is equal to or greater than a predetermined value and the elevator car opens the door and does not detect the waiting passengers for a predetermined time, the chime With a chime control means for re-ringing, even if the waiting passenger misses the chime when the elevator car arrives and does not board,
The chime is sounded again in response to the reaction of the waiting customer to call the attention of the waiting customer, and the arrival of the elevator car can be promptly noticed regardless of the waiting position of the waiting customer. Also,
When the elevator car arrives at the floor of the waiting passenger by the car control means, the chime is sounded, and the waiting passenger and the elevator car detected by the waiting customer position detecting means based on the image data from the television camera If the distance is equal to or greater than a predetermined value and the elevator car opens the door and a predetermined time has not passed and the passenger's boarding is not detected, the chime is re-triggered. Even if the driver misses and does not board, the chime is sounded again to call the attention of the waiting passenger, and the arrival of the elevator car can be promptly noticed regardless of the waiting position of the waiting passenger. Therefore, even if many elevator cars are installed side by side, regardless of the waiting position of waiting passengers on the floor,
It is possible to quickly notice that the elevator car has arrived.
