BACKGROUND OF THE INVENTION The present invention relates to a control device for a double deck elevator.

[0002]

2. Description of the Related Art In recent years, elevators have been required to have high transportation capacity with the increase in the number of skyscrapers and skyscrapers of buildings. In order to increase the transport capacity of elevators,
Although methods such as speeding up and increasing the efficiency of elevator operation can be considered, generally, the number of elevators is increased.

However, in order to increase the number of elevators, there is a problem that not only the equipment is added but also the floor area of the building is occupied to some extent. Moreover, even if the occupation rate of the building floor area is increased, the increase in transportation capacity does not increase in proportion to this.

For these reasons, a double deck elevator having a two-story car structure has been receiving attention in recent years. As shown in the schematic configuration diagram of FIG. 6, this double-deck elevator lands simultaneously on consecutive floors, for example, the first floor a and the second floor b, among the floors a to t on the first to twentieth floors. It consists of an elevator 3 with a two-story structure consisting of an upper car 1 and a lower car 2. The elevating body 3 is suspended by a hoisting rope 4 together with a counterweight 6, and is hoisted by a hoisting machine 5. This double-deck elevator normally jumps to the first floor, for example, the lower car 2 has the first floor a, the third floor c, and the fifth floor e.
.. on the odd floors of the upper car 1 on the 2nd floor b, 4th floor d, 6th floor f
.. will be operated so that they will stop on even floors. This is called double driving. However, if necessary, the upper car 1 and the lower car 2 are all floors except the standard floor,
In other words, even on odd floors or even floors, the vehicle may be driven to stop at any floor. This is called semi-double operation.

As described above, in a double-deck elevator operated in various modes, for example, in the case of double operation, even if the third car c is a non-stop floor for the lower car 2, it is 4 for the upper car 1. When there is a call at the platform on floor d,
Since the upper car 1 responds and stops landing on the fourth floor d, the lower car 2 will stop on the third floor c.

[0006]

However, if the elevator car stops at the non-stop floor, various problems will occur. For example, on an absolutely nonstop floor, the hall is blocked by walls and shutters, so if the elevator car door opens on the nonstop floor, passengers may accidentally fall into the hoistway or move up and down the elevator car. It may be caught between road walls and is extremely dangerous. To prevent such a danger, if the elevator car door is kept closed on the floor that is absolutely non-stop, the elevator car door will not open even if the elevator car stops. I feel, and if this state continues,
You could panic.

Even on a non-stop floor, if the elevator car door opens together with the landing door,
Although there is no concern about passengers being trapped in the car, leave the elevator car door open for a long time in order to wait for passengers in other cars to get on and off, while there are no elevator passengers in the car. This will cause passenger stress.

Further, when the floor to be made a non-stop floor is an important floor of the building and is set for the purpose of prohibiting the entrance and exit of persons other than those concerned, the elevator car door should be set on the non-stop floor. Opening compromises security significantly.

The present invention has been made in view of the above circumstances, and provides a controller for a double-deck elevator capable of ensuring passenger safety and eliminating passenger anxiety and discomfort. With the goal.

[0010]

To achieve the above object, the present invention provides a stop position detecting means for detecting the stop floor of each of the upper and lower cars of a double deck elevator, and a non-stop floor for setting a non-stop floor. The stop floor of one of the elevator cars detected by the setting means and the stop position detection means is a stopable floor, and the stop floor of the other car is equivalent to the non-stop floor set by the non-stop floor setting means. When it is detected that the elevator car is closed, the corresponding elevator car is prohibited from being opened and the elevator car is informed of the fact.

[0011]

According to the elevator control apparatus of the present invention, even when one of the elevator cars included in the elevator body is disabled when the stop position and the stop floor of the elevator body are detected by the stop position detecting means. When it is detected that the vehicle has stopped at the non-stop floor set by the stop floor setting means, the control means prohibits the opening of the corresponding elevator car and notifies the control means by the control means. As a result, the safety and security of passengers can be ensured and the anxiety and discomfort of passengers can be reduced.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a schematic configuration diagram of a double deck elevator to which an elevator control device according to an embodiment of the present invention is applied. As shown in FIG. 2, non-stop key switches 10a to 10t for making the floor non-stop are installed at the respective floors a to t on the first to the twentieth floors. Further, inside the upper car 1 and the lower car 2 of the lifting body 3, door opening buttons 9a, 9b and speakers 7a, 7b for informing the car are attached. On the other hand, a pulse generator 8 is directly connected to the hoisting machine 5 and has a function of generating a pulse for detecting the speed and position of the lifting body 3.

FIG. 1 is a block diagram showing the configuration of an embodiment of a control device 11 for a double deck elevator according to the present invention, and is particularly used for the double deck elevator shown in FIG. The control device 11 is the non-stop floor detection unit 1
2, stop position detection unit 13, stop position non-stop floor determination unit 1
4, an in-car notification unit 15, a door opening prohibition command unit 16, and a door driving unit 17.

As shown in FIGS. 1 and 2, the upper car 1 and the lower car 2 are provided with doors 19a and 19b, respectively.
It is opened and closed by door opening / closing motors 18a and 18b.
In addition, the upper car 1 and the lower car 2 have speakers 7a,
7b is installed, and these speakers 7a and 7b receive an audio signal from the in-car notification unit 15 and notify the passengers in the upper car 1 and the lower car 2 of this.

The non-stop floor detection unit 12 is a non-stop key switch 10a-10t installed at the landing of each floor.
The state set to (ON state or OFF state) is read at a constant time interval, and after detecting which floor is set as non-stop, the non-stop table shown in FIG. 5 is updated.

The stop position detector 13 detects the stop of the elevator 3 including the upper car 1 and the lower car 2 and the stop position thereof based on the pulse signal from the pulse generator 8 directly connected to the hoisting machine 5. . This stop detection is performed by counting the pulses from the pulse generator 8 at regular time intervals, for example, every 10 ms, and changing the count value. Further, the stop floor of the elevator car is detected following the detection of the stop of the elevator car. This is shown in FIG. 4 which is preset based on the number of pulses from the pulse generator 8 when the elevator car is stopped. , By referring to the floor / pulse correspondence table. That is,
By correlating the number of pulses from the pulse generator 8 with the landing floor in advance, the stop floor of the upper car 1 or the lower car 2 is detected from the number of pulses from the pulse generator 8. The stop position of the lifting / lowering body 3 detected here is sent to the stop position non-stop floor determination unit 14.

When the stop position detecting unit 13 detects the stop floors of the upper car 1 and the lower car 2, the stop position non-stop floor discriminating unit 14 detects the stop floors of the upper car 1 and the lower car 2 based on the information from the non-stop floor detecting unit 12. For the upper car 1 or the lower car 2 that is the floor,
Determine the stop floor or non-stop floor. If the floor where either the upper car 1 or the lower car 2 has stopped is the non-stop floor by the stop position non-stop floor discriminating unit 14, it is installed in the elevator car through the in-car notification unit 15. The passengers are informed that the floor is a non-stop floor through the speakers 7a and 7b. At the same time, the door open prohibition command section 16
Instruct to prohibit door opening. As a result, the door open buttons 9a, 9
the doors 19a, 19b sent from the b to the door drive unit 17
Since the signal for opening the car is prohibited, even if the passenger pushes the door open button 9a, 9b, the doors 19a, 19a of the elevator car to be non-stopped in the upper car 1 and the lower car 2
b does not open.

The signals of the door open buttons 9a and 9b provided on the upper car 1 and the lower car 2 are output to the door drive unit 17 via the door open prohibition command unit 16. Incidentally, the door open prohibition command unit 16 determines whether or not to receive the signals of the door open buttons 9a and 9b based on the signal from the stop position non-stop floor determination unit 14, and controls the operation of the door drive unit 17.

The operation of this embodiment will be described with reference to the flow chart shown in FIG. First, the stop position detector 13
When the elevator car is stopped, this is done by step S1.
In step S2, the stop floor i of the lower car 2 is detected. The stop position and the stop floor i are sent to the stop position non-stop floor discriminating unit 14, and the stop position non-stop floor discriminating unit 14 sets "1" to the stop floor i of the lower car 2 in step S3.
Is calculated and the stop floor of the upper car 1 is calculated. Then, the stop floor F = i or i + 1 is set and the process of step S4 is started.

In step S4, the stop position non-stop floor discriminating unit 14 discriminates whether or not the stop floor F is the non-stop floor based on the information in the table of the non-stop floor detecting unit 12. As a result of this determination, if neither the stop floor i of the lower car 2 nor the stop floor i + 1 of the upper car 1 is a non-stop floor, the process proceeds to step S1.
Although it shifts to 0, if any of them is a non-stop floor, it is determined in step S5 whether the lower car 2 is on the non-stop floor or the upper car 1 is on the non-stop floor.

If it is determined that the stop floor i is on the non-stop floor, the process proceeds to step S6 to prohibit the door open button 9b of the lower car 2 through the door open prohibition command section 16. So that the door 19b of the lower car 2 does not open. In this case, since the door opening button 9a of the upper car 1 is not prohibited, the door opening / closing motor 18 is operated through the door driving unit 17.
It is possible to drive a and open the door 19a. continue,
The processing of the stop position non-stop floor discriminating unit 14 proceeds to step S7, in order to notify the passengers through the in-car informing unit 15 to the speaker 7b installed in the lower car 2 that the vehicle is stopped on the non-stop floor. To broadcast. For example, this broadcast is performed as "This elevator is currently stopped on the non-stop floor. The door will not open, but please wait for a while." This broadcast, for example,
This is performed using a voice synthesizer (not shown) provided in the in-car notification unit 15. When the above process is completed, the process proceeds to step S10.

On the other hand, when it is determined in step S5 that the stop floor i + 1 is on the non-stop floor,
The process proceeds to step S8, the door open button 9a of the upper car 1 is prohibited through the door open prohibition command unit 16, and the upper car 1
Do not open the door 19a. In this case, since the door open button 9b of the lower car 2 is not prohibited, the door drive unit 1
7 to drive the door opening / closing motor 18b to move the door 19
b can be opened. Subsequently, the processing of the stop position non-stop floor determination unit 14 proceeds to step S9, and the in-car notification unit 1
5, the speaker 7a installed in the lower car 2 is caused to perform a broadcast for informing the passenger that the vehicle is stopped on the non-stop floor. When the above process is completed, the process proceeds to step S10. In step S10, it is determined whether or not to continue the process. If the process is to be continued, the process returns to step S3. If the process is completed, the process returns to step S1.

As described above, in the double deck elevator, when the upper car 1 or the lower car 2 is stopped at the non-stop floor, the door open buttons 9a, 9b of the car are prohibited so that the doors 19a, 19b are not opened. In addition, by notifying the passenger through the speakers 7a and 7b, danger can be prevented, security can be improved, and passengers' anxiety and irritability can be eliminated.

Further, even when the elevator car is stopped at the non-stop floor not only during normal operation but also during control operation in the event of an earthquake or disaster, the anxiety of passengers can be eliminated through the notification broadcast.

In the above embodiment, when the upper car 1 or the lower car 2 is stopped at the non-stop floor, the door opening buttons 9a and 9b are unconditionally prohibited and broadcasting is performed by the speakers 7a and 7b. However, the speakers 7a and 7b are used every time.
Broadcasting may be perceived as annoyed by passengers who are not familiar with it. In such a case, the speaker 7a,
The broadcast by 7b may be stopped, and when a passenger whose situation is unknown presses the door open button 9a, 9b, the notification broadcast may be performed via the speaker 7a, 7b.

Further, in the above-mentioned embodiment, the case where the passenger is informed that the vehicle is stopped at the non-stop floor by voice through the speakers 7a and 7b is exemplified, but other means such as a display device in the car is used. This may be notified to the passengers through.

[0027]

As described above, according to the present invention, when either the upper car or the lower car of the double deck elevator stops at the nonstop floor, the door open button is prohibited and the elevator car is Since it is configured to notify passengers that the elevator has stopped on the non-stop floor, it ensures passenger safety and passengers' anxiety when the elevator car door does not open even when the elevator has stopped. It is possible to obtain an effect that the discomfort and the security can be secured.
