The first entrance 201a and the second entrance 20
Assuming the flow of people entering and exiting the building 200 with the floor 1b, there is a space between the first floor or the second floor and upper floors (3rd to 6th floors), the first floor or the second floor, and a lower floor (the basement 1 (2nd floor to 2nd basement) is expected.
Therefore, the first entrance 201a, the second entrance 20
Those who enter the building from 1b and use the elevator are roughly classified into those who go to the upper floor and those who go to the basement. On the other hand, since the car 206 has no choice but to head to the upper floor or the lower floor, the elevator waiting time of the passenger becomes longer.

[0005] For example, considering a case where a user who is going from the second floor to the ground floor is waiting at the elevator hall on the second floor, if the elevator car 206 that has arrived is heading toward the upper floor, The passenger is in the car 206
After the car arrives at the 6th floor, it must descend and wait until it reaches the 2nd floor again.

Therefore, in order to reduce the waiting time of the passengers and improve the transportation efficiency, an elevator system in which a plurality of cars are arranged in one hoistway is conceivable. (For example, Japanese Patent Application Laid-Open No. 7-277615,

It is possible to constantly monitor whether or not b is the common stop floor as the destination floor, and switch the operation pattern as described later, and set each car according to one operation pattern determined from the combination of the current position and the destination floor. The operation of 11a and 11b can be controlled.

The operation control management unit 40 has a function of setting a plurality of operation patterns described later in advance, and the operation patterns are stored in each of the cars 11a and 11b.
By executing the control program that switches according to the current position and the destination floor of the car, the command to move the car 11a, 11b is sent to each of the control devices 7a, 7b according to each operation pattern. ing.

Hereinafter, each car 11 according to the present embodiment will be described.
The operation patterns a and 11b will be described with reference to FIGS. These figures show car 11
The positions of a and 11b are shown. The solid line indicates the current position of the car, and the broken line indicates the position of the next destination floor.
The arrows in these figures indicate the direction of the destination floor. The absence of the arrow indicates that there is no use request and that the car is in a stopped state.

(1) When the current positions of the two cars are both at a non-common stop floor FIG. 6 shows the upper car 11a and the lower car 1
It is a figure which shows the operation | movement pattern when both the present positions of 1b are non-common stop floors, and the next destination floors are also non-common stop floors. In this case, the two-handed car 11a, 11b
Since the intervals are provided, it is safe. However, the operation management device 40 determines that the interval between the car 11a and the car 11b is at least a certain distance based on the car position information of each of the cars 11a and 11b. , Each of the cars 11a and 11b is operated.

FIG. 7 shows that the current positions of the upper floor car 11a and the lower floor car 11b are both at a non-common stop floor, and one of the destination floors of the car 11a or 11b is a common stop. It is a figure showing an operation pattern at the time of a floor.

For example, the car 11b on the lower floor enters the first floor, which is a common stop floor, and the car 11a on the upper floor approaches the car 11b while the car 11a on the upper floor is This is the case when staying at the third floor, which is a non-common stop floor. In this case, both cars 11a and 11b are spaced apart from each other as in the operation pattern of FIG.
Although safe, the operation management device 40
While monitoring that the interval between the car 11a and the car 11b is maintained at a certain distance or more based on the car position information of the cars 1a and 11b, both or one of the cars 11a and 11b is operated.

FIG. 8 shows a case where the current positions of the upper floor car 11a and the lower floor car 11b are both at the non-common stop floor, and both the cars 11a and 11b have the common stop floor as the destination floor. It is a figure showing an operation pattern of.

In this case, the cars 11a, 1
Since both vehicles 1b enter the common stop floor of the first and second floors within a certain period of time, in order to ensure safety so that they do not collide, cars 11a and 11b are respectively set in advance.
, For example, car 1 on the upper floor
If it is assumed that 1a has a higher priority, the car 11a is moved to the second floor in priority to the lower car 11b. During this time, the lower priority car 11b waits until the higher car 11a has finished moving from the second floor of the destination floor to the third or higher non-common stop floor. Thereafter, the operation management device 40 checks that the distance between the car 11a and the car 11b is at least a certain distance from the car position information of each of the cars 11a and 11b, and then moves the car 11b to its destination. Enter the first floor.

In this embodiment, since the building has only two common stop floors and a small number of floors, the lower priority car 11a is moved until the higher priority car 11a moves to the non-common stop floor. 11b is on standby, but depending on the situation of a building having a large number of common stop floors, the low-priority car 11b may be moved to the low-priority car 11a in the traveling direction of the high-priority car 11a. It is also possible to wait until it matches the traveling direction, enter the common stop floor after confirming that the distance between the cars is equal to or more than a certain value.

In the operation management device 40, the car 1
Priorities assigned to 1a and 11b in advance can be set so that they automatically change according to the time of day, day of the week, usage frequency, and the situation of the building, and an elevator administrator is required. It can be set arbitrarily at any time according to.

(2) When the current position of one of the cars is at a common stop floor and the current position of the other car is at a non-common stop floor, FIG. 9 shows that the current position of the upper car 11a is It is on the second floor of the common stop floor and stops without a request for use. The current position of the lower car 11b is on the non-common stop floor, and the next destination floor is also the first basement floor of the non-common stop floor. It is a figure showing an operation pattern in a certain case.

In this case, there is no situation in which both the cars 11a and 11b enter the common stop floor, and the two cars 11a and 11b are spaced apart from each other. Is each car 11
The car 11b is operated to the first basement floor of the destination floor while monitoring that the distance between the car 11a and the car 11b is kept at least a certain value based on the car position information of the cars 11a and 11b.

FIG. 10 shows an upper car 11a at a common stop floor and a lower car 11 at a non-common stop floor.
It is a figure which shows the operation | movement pattern at the time of making the 1st floor which is both a common stop floor the destination floor.

In this case, the cars 11a, 1
Since both cars 1b will enter the first floor, it is necessary to adjust the operation so that no collision occurs. Therefore, the car 11a on the upper floor side of the common stop floor is preferentially moved to the first floor. During this time, the lower priority car 11b has the higher priority car 11a on the destination floor.
Wait until the transfer from the floor to the non-common stop floor of three or more floors is completed. Thereafter, the operation management device 40 determines the car 1 based on the car position information of each of the cars 11a and 11b.
After confirming that the distance between the car 1a and the car 11b is at least a certain value, the car 11b is made to enter the first floor, which is the destination floor.

In this embodiment, since the building has a small number of common stop floors, ie, two floors, the car 11a at the common stop floor operated preferentially moves to the non-common stop floor. Although the car 11b at the common stop floor waits, depending on the situation of a building having a large number of common stop floors, the car 11b waits until the traveling directions of the car 11a match, and the car 11b waits. After confirming that the mutual interval is maintained at a certain value or more, the vehicle may enter the common stop floor.

FIG. 11 shows that the upper floor car 11a at the common stop floor is stopped without a use request and the lower floor car 11b at the non-common stop floor is a common stop floor.
It is a figure showing an operation pattern in the case of making a floor the destination floor.

In this case, the car 1 on the common stop floor
1a is evacuated to a non-common stop floor, for example, the third floor. After the movement, the operation management device 40 sets each car 11
After confirming that the distance between the car 11a and the car 11b is at least a certain distance from the car position information of the cars 11a and 11b, the car 11b is made to enter the first floor, which is the destination floor.

In a building having a large number of common stop floors, if a car at a non-common stop floor enters the common stop floor without impeding the operation, the ride stopped at the common stop floor. The car may simply be evacuated to an appropriate floor of a common stop floor that is safe for operation, and if it is not necessary to evacuate, it is not necessary to evacuate the car.

(3) When the Current Positions of the Two Cars are Both at the Common Stop Floor FIG. 12 shows that the upper car 11a and the lower car 11b are both at the common stop floor. FIG. 6 is a diagram showing an operation pattern when there is a use request in both cases.

In this case, the car is operated only when the traveling directions of the cars 11a and 11b match. That is,
The operation management device 40 allows the car 11a to enter the third floor, which is the destination floor, while securing a certain distance or more between the car 11a and the car 11b from the car position information of each of the cars 11a and 11b. Then, the car 11b enters the second floor.

If the distance between the cars 11a and 11b is shorter than a predetermined distance, the operation management device 4
In FIG. 5, 0 instructs at least one of the control devices 7a and 7b of the car to issue a stop command, and the control devices 7a and 7b that have received the command stop the drive devices 3a and 3b. Thereby, even if the cars 11a and 11b approach each other abnormally, their collision can be prevented beforehand and safety can be further improved. Note that, in place of the stop command, a command to emergency-stop the governor 14 may be given.

The distance to be maintained between the cars 11a and 11b is equal to or greater than the distance traveled from when the emergency stop device 104 of FIG. 4 is activated to when the cars 11a and 11b stop. As a result, the upper car 11
Even if the suspension rope 4a of a is broken and the car 11a falls, the safety device 104 can be operated before the car 11b on the lower floor collides to prevent the collision, so that the safety can be further enhanced. it can.

FIG. 13 shows that one of the cars, for example, the car 11a on the upper floor has no use request and is stopped on the second floor, and the other car 11b is on the second floor where the car 11b is stopped. It is a figure showing an operation pattern in the case of making it a floor.

In this case, the car 11b operates as follows so as not to become stuck. That is,
The stopped car 11a is evacuated to a non-common stop floor, for example, the third floor. After the movement, the operation management device 40
After confirming that the distance between the car 11a and the car 11b is at least a certain distance from the car position information of each car 11a and 11b, the car 11b enters the first floor which is the destination floor. Let it.

In a building having a large number of common stop floors, if a car at a non-common stop floor enters the common stop floor without impeding the operation, the ride stopped at the common stop floor The car may be simply evacuated to an appropriate common stop floor that is safe for operation, and if it is not necessary to evacuate, it is not necessary to evacuate the car.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited by the number of floors of a building, and may have only one common floor. Further, even if three or more elevators are installed in one hoistway, the present invention can be applied to a set of two vertically adjacent elevators.
