DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a multiple deck elevator in which a plurality of independent cabs are vertically connected in a single car frame.

[0002]

2. Description of the Related Art In a multiple deck elevator, the distance between floors of a building to be installed is designed to be the same, and the distance between floors of cascades to be installed is also the same. As a result, other cabs also achieve zero steps by controlling landing so that the floor level of the reference cab at the time of landing matches the floor level of the hall, that is, the steps are zero. can do. However, the actual floor-to-floor distance of an actually-built building usually causes some errors with respect to that of design. For multiple deck elevators where the distance between the floors of the cabs is constant, this error may occur when the floor of the elevator hall and the floor of the cab are landed so that the step between them is zero. Appears as a step in the basket room.

In a conventional multiple deck elevator,
In order to reduce the above-mentioned level difference, a system that can adjust the distance between the floors of the cab as a structure that can adjust the cab up and down with respect to the car frame by some means, or a landing detection device individually for each cab A method of disposing and distributing steps has been proposed.

SUMMARY OF THE INVENTION Among the above prior arts,
In the method of adjusting the distance between the floors of the cab, complicated devices need to be incorporated into the cab frame and the cab in order to move the cab with respect to the cab frame, thereby increasing the cost and moving the elevator by increasing the weight. Additional problems, such as increasing the energy required for the operation or requiring complicated control.

[0005] The method of installing a landing detection device for each car room requires a landing detection device corresponding to the number of floors, resulting in high costs and a long time for adjustment and maintenance thereof. there were.

[0006] Furthermore, if the error in the distance between the floors of the building is large and a step exceeding a predetermined value remains after the steps are distributed to the upper cab and the lower cab, or due to a control error of the landing controller. When the distribution of the steps is biased and one of the steps exceeds a predetermined value, the passenger may stumble and cause an accident, and there is a shortage of consideration for the safety of the passengers.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a control device for a multiple deck elevator which does not require a complicated device and does not cause a large step even if an error occurs in the floor-to-floor distance of a building. .

[0008] A further object of the present invention is to provide a floor control device in which the error between the floors of a building is large and a step exceeding a predetermined value remains after the steps are distributed to the upper cab and the lower cab. Provided is a control device for a multiple deck elevator that can prevent a passenger from tripping accident and improve safety even when the distribution is biased due to a control error and one step exceeds a predetermined value. It is in.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the invention according to claim 1 controls a multiple deck elevator in which a plurality of independent cabs are vertically connected in one car frame. In the apparatus, a landing detection means for detecting a difference between the floor level of the cab and the floor level of the hall as a step as a detection target of a specific cab of the plurality of cabs, and a detection target of the landing detection means. The difference between the floor level of the cab and the floor of the hall on the corresponding floor of the other cab when the car occupies the floor with zero step is set for each stop floor. When landing on an arbitrary floor, reference is made to the stored contents of the step storage means and the storage contents of the step storage means at the time of landing on an arbitrary floor so that the maximum value of the steps of each car on the landing floor becomes smaller. Correct the steps detected by the floor detecting means A landing correction means, a landing control means for performing landing control based on the cab which is a detection target based on the corrected step by the implantation correcting means,
When the level difference in the cab after landing exceeds a predetermined value, the passengers in that cab should be careful of getting on and off because there are steps.
And a notifying means for notifying the user of the fact.

According to a second aspect of the present invention, in the control device for a multiple deck elevator according to the first aspect, the landing correction means is configured to control a landing on a certain floor when there is no wheelchair hall call or wheelchair car call. When the floor is referred to the stored contents of the step storage means, the step detected by the landing detection means is corrected so that the maximum value of the steps in each car room is reduced, and there is a wheelchair hall call or a wheelchair car call. Is characterized in that the step detected by the landing detection means is corrected so that the maximum value of the steps in the cab which is the object of the wheelchair hall call or the wheelchair car call becomes smaller.

Embodiments of the present invention will be described below with reference to the drawings.

<First Embodiment> (Structure and Operation of First Embodiment) FIG. 1 shows an embodiment of the first aspect of the present invention.
Of the upper cab room 2 and the lower cab room 3 fixed to one car frame 1, the floor level of one of the cab rooms, for example, the upper cab room 2, is detected, and the floor level of the upper cab room 2 and the floor where the floor has landed are detected. A landing detection device 5 that outputs a difference from the floor level, that is, a landing signal 4 representing a step is provided. The landing signal 4 is input to the landing correction device 9. In addition, when the upper cab 2 stops at a zero step at each stop floor where the upper cab 2 stops, the step between the floor level of the lower cab 3 and the floor level of the corresponding hall is defined as a table. And a step storage table 6 stored in advance. The landing correction device 9 obtains the level difference signal 7 of the floor to be landed from the level difference storage table 6 when the cab arrives, and distributes the level difference between the upper cab room 2 and the lower cab room 3. The landing signal 4 is corrected and the corrected landing signal 8 is output so that the step having the maximum value is smaller so that only the cab does not have a large step. The car position is controlled by the landing control device 10 so that the upper cab 2 is placed at a position where the corrected landing signal 8 becomes zero.
The landing signal 4, the level difference signal 7, and the corrected landing signal 8 are expressed as positive when the cab is shifted above the reference position and negative when the cab is shifted below.

The apparatus shown in FIG. 1 calculates a step in each car from the landing signal 4 and the step signal 7 after landing, and issues an announcement signal 11 when the absolute value of the step exceeds a predetermined value. And a step announcement device 13 which gives an announcement to passengers in each car through the speakers 121 and 122 installed in the upper car room 2 and the lower car room 3 to the effect that "there is a step, so be careful when getting on and off". Is provided.

The operation of the device of FIG. 1 will be described in more detail with reference to FIGS.

As shown in FIG. 2, the upper cab 2 is on the nF floor,
When the lower car room 3 lands on the (n-1) F floor, the floor-to-floor distance L1 between the upper car room 2 and the lower car room 3 is L.
2 (L1> L2 in the illustrated example)
Lower cab 3 when upper cab 2 is stopped at zero step
Is stored in advance in the step storage table 6 as a value corresponding to the nF floor of the upper cab 2. At this time, the landing correction device 9 corrects the landing signal 4 as follows: corrected landing signal = landing signal + (1/2) · LA (1). That is, in this case, by dividing the step LA into the upper cab 2 and the lower cab 3, the upper cab 2 is raised above the reference level with a (1/2) · LA step as shown in FIG. After landing, lower cab 3 is (1 /
2) Land below the reference level with a step of LA. In this way, both the upper cab 2 and the lower cab 3 have a step of (1/2) · LA.

(Effects of First Embodiment) According to the first embodiment, the step LA is divided into the upper cab 2 and the lower cab 3 so that no particular step is generated in a specific cab. Thus, the maximum step can be made smaller.

Further, when the error of the floor-to-floor distance of the building is large and a step exceeding a predetermined value remains even after the step distribution, or the control error of the landing control device 10 causes the distribution to be biased. If the specified value is exceeded, an announcement will be made to alert passengers,
Safety can be improved by preventing passengers from tripping accidents.

(Modification to First Embodiment) In the above-described embodiment, the number of cabs is two in the upper and lower cabs. However, the present invention can be applied to the case of three or more cabs. In this case, among the plurality of cabs, the corrected landing signal = landing signal + (1/2) · (LA1 + LA2) using the largest step LA1 with a positive value and the largest step LA2 with a negative value. By correcting as (2), the steps can be sorted.

In the above-described embodiment, as the notification means,
Although the speakers 121 and 122 and the step announcement device 13 are installed in the car room, the speakers may be installed in the hall. In addition to announcement devices that appeal to the auditory sense in words, display devices that appeal to the sight, buzzers that appeal to alarm sounds,
The notification may be made by using chimes alone or in combination.

<Second Embodiment> (Configuration and Operation of Second Embodiment) An embodiment of the second aspect of the present invention will be described with reference to the control device of FIG. The embodiment described here is characterized in that the landing correction device 9 performs correction so that a step in the cab responding to a wheelchair hall call or a wheelchair car call during landing does not become large.

When both the upper cab room 2 and the lower cab room 3 land in response to a wheelchair hall call or a wheelchair car call, as in the first embodiment, the floor is corrected by the landing correction device 9. The signal 4 is corrected in accordance with the equation (1) to obtain a corrected landing signal such that both the upper cab 2 and the lower cab 3 land with the same step LA. However, if only the upper cab 2 responds to the wheelchair hall call or the wheelchair car call at the time of landing, the step LA of the lower cab 3 is left as it is and the step of the upper cab 2 is taken into account without paying attention to the step adjustment. By taking only the above into consideration, the corrected landing signal = landing signal ... (3) As shown in Fig. 2, the upper cab room 2 that responds to the wheelchair hall call or the wheelchair car call is landed with no step. .

When only the lower car room 3 responds to a wheelchair hall call or a wheelchair car call at the time of landing, it is not necessary to consider the steps of the upper car room 2 but only the steps of the lower car room 3. By correcting as follows: corrected landing signal = landing signal + LA (4), as shown in FIG. 4, the upper cab 2 is landed upward by LA, and responds to a wheelchair hall call or a wheelchair car call. The lower car room 3 can be landed with no step.

(Effects of Second Embodiment) According to the second embodiment, when one of the cabs gets on the floor in response to a wheelchair hall call or a wheelchair car call,
By landing on the cab so as not to cause a step, the safety of the wheelchair user can be prioritized. Also, if both cabs land in response to a wheelchair hall call or a wheelchair car call, avoiding a large step in both cabs will result in an extremely large cab. A step can be avoided.

(Modification Example of Second Embodiment) In the case where a step in a cab that responds to a wheelchair hall call or a wheelchair car call is prevented from forming a step, the step in another cab becomes large. Steps may be allowed within a range where there is no problem in getting on and off with a wheelchair, and correction may be made so that the steps in other cabs are made slightly smaller.

When both cabs land on a floor in response to a wheelchair hall call or a wheelchair car call, if both cabs have a large step, one of the cabs is first landed with no step. Let the cab open,
After getting on and off, the other cabs may be re-landed so that the step is zero, and only the cabs may be opened and the passengers may get on and off.

[0026]

According to the present invention, an error occurs in the floor-to-floor distance of the elevator hall of the building, and as a result, a discrepancy occurs between the floor-to-floor distance of the upper and lower cabs in the multiple deck elevator. Even when there is a floor, it is possible to land the floor so that there is no large step between the floor of the cab and the floor of the hall at the time of flooring, without requiring complicated equipment. If the error of the floor-to-floor distance of the building is large and a step exceeding a predetermined value remains even after the step distribution, or the distribution is biased due to a control error of the landing control device, one of the steps exceeds the predetermined value. If this happens, an announcement is issued to alert passengers to caution, thereby preventing passengers from tripping accidents and improving safety.
