Abstract

PROBLEM TO BE SOLVED: To deal with much boarding from the middle floor of a building at a boarding peak time by stopping the second, i.e., subsequent deck, of an elevator car at the middle floor, and accordingly enabling remaining passengers to subsequently start with a current car. SOLUTION: By determining the existence of passengers remaining in an elevator area 30 without being dealt with, the stopping of a subsequent deck 16 is decided. First, after an upper, i.e., a preceding deck, is stopped, the remaining of passengers 32 without being dealt with in a lobby 30 is determined by a system. Then, by moving up a car 12 by one floor, similarly, a lower, i.e., a subsequent deck 16, reacts to deal with a floor 20 where the passengers 32 are remaining. Then, the passengers 32 remaining at the lobby board get on the other deck of the car 12, and accordingly the car 12 is started while the two decks are full of passengers.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for operating a double deck elevator car.

[0002]

2. Description of the Prior Art In the elevator industry, the installation of double-deck elevator cars is well known and is used particularly in high-rise, high-traffic buildings. A double-deck elevator is a single elevator car that includes two vertically adjacent decks simultaneously corresponding to two vertically adjacent floors. Such a double-deck elevator is excellent when moving a large number of passengers from a double-floor lobby to a building floor upstairs. Such a system is particularly useful at the peak of the morning climb when many passengers want to enter the building and climb to the desired floor.

[0003] At times other than the peak of the morning climb, the double-deck car travels in the building from one floor of the intermediate floor to another floor, and carries passengers to the lower lobby floor to move throughout the building. . During these off-peak hours,
It is customary that the trailing deck of the elevator car answer hall calls in that direction on the intermediate floor. Thus, in an elevator moving in a descending direction, the upper or subsequent deck will respond to the next descending hall call. The lower deck is used for cars that move in the ascending direction in response to an ascent hall call. The purpose of the prior art operating method is to allow, at each stop, a preceding deck to carry passengers on the next adjacent floor in the direction this car is heading.

The majority of traffic occurs between the double-floor lobby and the upper floors of the building, and the flow of passengers in the middle of the building is only slightly incidental. The operation is carried out without any trouble.

[0005]

Whether the intermediate floor is designated as an important source of traffic (ie, destination) within the building,
Or, in that case, the prior art methods cannot operate more efficiently than single deck elevator cars in terms of receiving and transferring passengers in the building. There is a need for a method of operating a double-deck elevator system that can take advantage of the additional capacity of a double-deck car to accommodate a large number of rides from intermediate floors.

[0006] It is an object of the present invention to provide an improved response to the mid-floor of a building during peak ride times.

[0007]

SUMMARY OF THE INVENTION In accordance with the present invention, a double-deck elevator system is operated to accommodate an intermediate floor of a building. During a predetermined time period during which a peak of passengers is present on the intermediate floor, in response to a hall call directed to a specific direction, the car is operated so as to stop the leading deck of the car approaching this floor on this floor.

[0008] The method of the present invention determines whether after boarding the leading deck, any passengers who could not be accommodated due to reaching the substantial capacity of the leading deck remain on this intermediate floor. . If the system determines that there may still be more passengers waiting in the current direction, the method of the present invention stops the second or subsequent deck of the elevator car at its intermediate floor, thereby leaving the remaining Allow passengers to continue departure in their current car.

Thus, the method according to the invention provides twice the opportunity for a passenger to enter a car for a departure from an intermediate passenger floor at a given time when a large number of rides are required. .

BRIEF DESCRIPTION OF THE DRAWINGS The method according to the invention will now be described with reference to the drawings, and in particular to FIG. FIG. 1 shows the hoistway 14
1 shows a schematic view of a building 10 having a double-deck elevator car 12 operating in a car. Double deck basket 12
Has a lower deck 16 and an upper deck 18 to accommodate two adjacent floors 20 in the building 10.
Correspondence to passengers entering the building from the main entrance 22 is provided from the double-floor lobby 24 and the elevator car 1
Getting on and off to 2 is performed on odd and even floors.

As noted above, except for the upward movement from the double-floor lobby 24, double-deck elevators typically include a subsequent deck, such as the lower deck 16 of a car moving in an ascending direction. This is done by responding to all ascending hall calls on the ten intermediate floors 20. For this application to work, the intermediate floor 20 must be a floor other than the double-floor lobby floor 24 and the top floor 26.

As further noted above, the prior art method of responding to hall calls by subsequent decks involves an intermediate floor 20.
Works well except in buildings where is always the main departure floor or, depending on the time of day, the main departure floor. In this case, prior art methods of responding to hall calls with the subsequent deck of the double deck elevator car 12 do not take full advantage of the capacity of the double deck car.

In accordance with the present invention, the middle floor 20 with a high number of departure passengers is served by the leading deck of the double deck car 12 at least while the number of departure passengers there is expected to be high. For example, referring to FIG. 2, while the number of departure passengers is large, the car 1 that moves in the ascending direction 34 in response to a hall call in the ascending direction from the intermediate floor 30 with many departure passengers
2 first stops the upper deck 18 of the car 12 to accept a passenger 28 having a destination in the ascending direction.

In the lobby area 30 of the intermediate floor 20, if the number of passengers having destinations in the ascending direction is sufficient to fill the predetermined capacity of the upper deck 18, the method according to the present invention will be described. To correspond to the intermediate floor 20 at the lower or subsequent deck 16, thereby allowing the remaining passenger 32 with a destination in the ascending direction of the car 1 to stand still, as shown in FIG.
To be able to ride 2. Thus, the method according to the present invention utilizes the car 12 to its full capacity to move passengers on the intermediate floor 20 of the building 10.

In this method, it is determined whether or not the subsequent deck 16 is to be stopped by determining whether there is a passenger left in the elevator lobby area 30 without being handled.
This may be achieved in various ways, two of which are disclosed for illustrative purposes. The first method involves using the load measurement capabilities of the elevator system.

By determining the load on the elevator car 12, the method according to the present invention can determine the approximate number of passengers 28 who have boarded the upper deck 18 in the previous example. Since the expected number of passengers will approach the capacity of the deck, the method according to the present invention may be used to increase the destination in the ascending direction because the capacity of the upper deck is approaching full and the upper deck is unable to ride because it is full. Is determined to remain in the floor lobby area.

Another technique for determining the presence of unresponsive passengers after boarding a preceding deck is through a sensor 34 located in the lobby 30 of the floor 20 with a high number of passengers. Following the preceding or upper deck 18, the sensor 34 detects the presence of the passenger 32 in the lobby area 30.
When the presence of the passenger is recorded and displayed, the system determines that unresponsive passengers still remain in the lobby 30.

By these or other measures or means, it can be seen that unresponsive passengers 32 remain in the lobby 30 after the suspension of the upper or leading deck 18, as shown in FIG. If the system determines, this method will react by moving the car 12 up one floor so that the lower or subsequent deck 16 will correspond to the floor 20 in question, and the remaining passengers 32 in the lobby will Ride on the other deck of this car 12, thereby allowing the two decks to leave car 12 as shown in FIG.

As will be apparent to those skilled in the art, the method according to the present invention for accomplishing the filling of two decks with passengers entering from an intermediate floor involves a conventional system in which only subsequent decks are used full. In comparison, it increases the capacity of the whole system and reduces the waiting time of passengers.

It will be apparent to those skilled in the art that various modifications may be made to the above description without departing from the spirit and scope of the invention.
