Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation control device for a double-deck elevator, and more particularly, to an elevator machine in which the service for the user is temporarily lost, when the user next arrives. The present invention relates to an operation control device for a double-deck elevator that performs a standby operation of traveling in advance and waiting on a floor.

[0002]

2. Description of the Related Art In order to increase the effective use area in a building, there is a method of reducing the area of a hoistway by adopting a double deck elevator having a car connected vertically. The operation system of this double-deck elevator can be roughly classified into two types: a system in which the upper floor is restricted to an even-numbered floor, and a lower car is restricted to an odd-numbered floor (or vice versa). There is a method of providing service using only one of the cars.

[0003] In the first method, the number of floors to be stopped is about half that of the other two methods, and efficiency is improved by utilizing the features of the double deck elevator. For this reason, Japanese Patent No. 1577184 discloses that, when performing a standby operation in which an elevator car having no service for a user temporarily runs and waits on a floor in advance in preparation for the next arrival of a user. Also disclosed is a method for maintaining the even and odd floors of the upper and lower cars.

[0004]

The basic concept of the standby operation is to reduce the waiting time of the user on the standby floor by making the elevator machine wait in advance on the floor expected to be frequently used. . Therefore, even in the case of using a double-deck elevator having a car connected vertically, it is important to make a standby in advance on a floor which is expected to use a lot of the connected second floor in advance.

In the prior art described above, even during standby operation, the use of two connected floors is not considered in order to maintain the even and odd floors of the upper and lower cars.

An object of the present invention is to provide an operation control device suitable for performing efficient standby operation in a double deck elevator.

Another object of the present invention is to reduce the waiting time of a user.

[0008]

In order to achieve the above object, a plurality of double deck elevators having a car connected vertically, a hall call means for receiving a user's use request, and a Operation control means for determining the double deck elevator to be serviced, learning means for learning the operation status of the hall calling means and the usage status of the double deck elevator by statistical processing, and the double deck elevator using the usage status learned by the learning means. And a waiting floor determining means for determining a floor to be driven and waited in advance.

In one embodiment of the present invention, the waiting floor determining means selects the most occupied floor with the highest usage status, compares the usage status of the floors above and below the most occupied floor, and determines which floor has the highest usage. And the standby floor is determined so that the double deck elevator stops at the same time and the most frequently used floor.

[0010] In another embodiment of the present invention, the standby floor determining means uses the value obtained by adding the usage statuses of the two upper and lower floors connected to each other to determine which floor is the most frequently used in the total of the continuous two floors. Is selected, and the standby floor is determined so that the double deck elevator stops simultaneously on the continuous second floor.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a view for explaining the basic concept of determining a standby floor according to the present invention.

FIG. 1 shows an example of usage per hour when there is a traffic demand of a 10-story building.

The basic concept of standby operation, in which an elevator car temporarily deprived of service for the user is run in advance on a floor to be ready for the next arrival of the user and waits, is that there are many uses. By waiting the elevator at the expected floor in advance, the waiting time for users on the standby floor is reduced. Therefore, even in the case of using a double deck elevator having a car connected vertically, it is important to make a standby in advance on a floor which is expected to use a lot of the connected second floor in advance.

The first concept for this purpose is to place the highest priority on the seventh floor, which has the largest number of users as a single floor in FIG. 1, and wait for the elevator which has no service for the user temporarily on the seventh floor. Shall be allowed. At this time, in the double deck elevator with a car connected vertically, it stops at the 6th and 7th floors, and the 7th and 8th floors
It is possible to stop both at the floor and stop. However, if the basic concept of standby operation is to be applied in which the vehicle is expected to wait at the floor expected to be heavily used, compare the usage of the 6th floor and the 8th floor. It can be expected that waiting on the sixth floor with more usage will have a higher probability of waiting than on the eighth floor with less usage. Therefore, it is determined that the standby floor of the double deck elevator is stopped at the 6th floor where the usage is higher and the 7th floor of the highest usage at the same time.

The second concept is to emphasize the characteristics of a double deck elevator that can simultaneously stand by on the second floor, and
The standby floor is determined based on the total value of the use of floors. Referring to the total value of the number of occupants on the continuous second floor shown in the column on the right side of FIG. 1, the value obtained by adding the occupancy on the second and third floors is the largest usage as a whole. Therefore, it is determined that the standby floor of the double deck elevator is simultaneously stopped on the second floor and the third floor where the number of occupants of the continuous second floor is the largest.

Hereinafter, the configuration of an operation control device for realizing the above-described basic concept of the present invention and its processing will be described.

FIG. 2 is a diagram showing a system configuration according to one embodiment of the present invention.

A plurality of double-deck elevators 1
Numeral 0 includes an upper car 11 and a lower car 12 which are connected cars up and down. An operation control device 20 that operates a plurality of double-deck elevators 10 includes a learning unit 21
And a standby floor determining unit 22 and an operation control unit 23 corresponding to standby floor determining means that are the gist of the present invention. The hall call button 30 is provided in the elevator hall on each floor to receive a use request from a user.

The use request signal input by the user operating the hall call button 30 is transmitted to the operation control device 20.

The operation control unit 23 of the operation control device 20 receives the status signal of the position of each double deck elevator car 10, the number of people in the car, etc., and sends each double deck to the floor where the user who issued the use request signal waits. Elevator unit 10
The arrival state of the car is predicted, the double deck elevator car 10 serving the user is determined, and the operation control of the double deck elevator car 10 is performed according to the decision. In addition, the operation control unit 23 performs an entire operation control process including a standby operation in which the double-deck elevator No. 10 in which the service for the user temporarily disappears is temporarily run in advance to a standby floor determined by the process described below and waits. Execute

The learning unit 21 in the operation control device 20
Using the use request signal by operating the hall call button 30 and the car status signal such as the position from each double deck elevator car 10 and the load in the car, the use situation of the user is learned and recorded by a technique such as statistical processing.

In the description of the present embodiment, only the parts related to the gist of the present invention are described in detail, and the learning unit 21, the operation control unit 23 and the like are well known in the operation control device of a normal single deck elevator and double deck elevator. A description of a portion to which a public technology can be applied is omitted.

FIG. 3 is a flowchart for explaining one embodiment of the standby floor determination processing executed by the standby floor determination unit 22 in the operation control device 20.

The first standby floor determination processing 100 is performed, for example, by
It is assumed to be started periodically, such as 00 ms, or to be started in response to a service status signal from the double deck elevator car 10 that indicates service completion.

In step 101, learning data is read from the learning section 21.

In step 102, the most frequently used floor is selected with reference to the learning data. In step 103, the use status of the floors connected above and below the selected most occupied floor is compared. If there is more occupancy on the upper floor, in step 104 the lower car 12 waits for the most occupied floor (at the same time, A standby command is set so that the upper floor connected to the use floor is on standby by the upper car 11). If there is more use of the lower floor in step 103, the upper car 11 stands by at the most occupied floor in step 105 (at the same time, the lower car 12 stands by on the lower floor connected to the most occupied floor). Set the command.

In step 106, the standby command determined in step 104 or 105 is transmitted to the operation control unit 23, and the operation control unit 23 executes standby operation.

According to the present embodiment, there is an effect that the waiting time reduction of the most frequently used floor in a single floor can be achieved with the highest priority.

FIG. 4 is a flowchart for explaining another embodiment of the standby floor determination processing executed by the standby floor determination unit 22 in the operation control device 20.

The second standby floor determination processing 110 is also performed, for example, by 1
It is assumed to be started periodically, such as 00 ms, or to be started in response to a service status signal from the double deck elevator car 10 that indicates service completion.

In step 111, learning data is read from the learning section 21.

In step 112, using the learning data, the usage data for two consecutive floors (which can be stopped and serviced simultaneously) is added to calculate.

In step 113, the most frequently used two consecutive floors are selected with reference to the added data.

In step 114, a standby command is set so that the upper car 11 and the lower car 12 simultaneously wait on the selected two consecutive floors.

In step 115, the standby command determined in step 114 is transmitted to the operation control unit 23, and the operation control unit 23 executes standby operation.

According to the present embodiment, there is an effect that the waiting time of the most frequently used floor among the combination of consecutive two floors can be reduced with the highest priority.

Here, as an embodiment of the present invention, 2
Although described using an example, this can be configured to use only one of them, or configured to switch according to the situation of traffic demand. When multiple double-deck elevators have no users to be serviced at the same time, the first is the first
It is of course possible for the second machine to determine the standby floor by the second standby floor determination processing 110 by the standby floor determination processing 100.

Also, in this embodiment, all the service floors have been described as being continuous. However, if there is a non-service floor in the middle floor, the non-service floor is excluded from the standby floor, If there is a passing floor, it may be necessary to extend the two floors sandwiching the express passing floor so that they are not continuous floors. Even in such a case, the gist of the present invention in which the standby floor is determined based on the usage status of the two consecutive floors that can be simultaneously serviced is unchanged, and it is obvious that the present invention can be realized within the scope of the present invention.

Although the present invention has been described with a plurality of double deck elevators, it goes without saying that the present invention can be applied to a single double deck elevator without any problem.

Alternatively, in the description of the present invention, it has been described that the determination of the standby floor is entirely determined by the learning result of the use situation in the learning unit 21, but in particular, the floor in which the priority is given to the reduction of the waiting time is manually determined, and the floor is determined. The present invention also includes a configuration in which the standby floor of the double deck elevator is determined according to the use status of the upper and lower floors.

[0042]

As described above, according to the present invention, there is an effect that it is possible to provide an operation control device suitable for performing efficient standby operation in a double deck elevator.

Further, according to the present invention, there is an effect that the waiting time of the user can be reduced.
