Description

Car stopping method of elevator system

Technical Field

The invention belongs to the technical field of elevators, and particularly relates to a car stopping method of an elevator system.

Background

In modern society and economic activities, elevators have become indispensable people-or load-carrying vertical transport means. Since 1854 elevator invention, an elevator car runs in a traction driving mode by adopting a steel wire rope wheel, and a machine room, a traction motor and a speed reducer are arranged on the top layer of a building to drive a steel wire rope to pull the car and a counterweight to run on a track in a hoistway. This drive allows for generally only one car to be operated within a single hoistway, and a single car mode of operation provides for a low-rise, low traffic floor. With the rapid development of modern cities, the defects of long waiting time and low conveying efficiency of the elevator in a single-car running mode are continuously amplified from the beginning of pulling out high-rise buildings and super-high-rise buildings with large population density, and the traditional single-car elevator running mode is difficult to adapt to the rapid development requirement of the modern city buildings.

In order to improve the utilization rate of building space and the transportation efficiency of the elevator and reduce the manufacturing cost of the building and the elevator, along with the continuous development of engineering technology level, a multi-car parallel elevator is being developed and applied. The multi-car parallel elevator adopts a traction-wire-rope-free direct driving technology, so that a plurality of elevator cars can be operated in the same hoistway at the same time, and the elevators among the various hoistway can be mutually switched to operate in the hoistway, thereby realizing overrun operation.

However, when taking a ladder in many buildings, a part of the area needs to be authorized to enter, for example, in many hotels and office buildings, if a user thinks of reaching certain floors after entering the elevator, the user needs to swipe a card and then press a button of a target floor. In a conventional elevator, the hoistway corresponding to the car when entering the elevator and the hoistway corresponding to the car when leaving the elevator are identical, and therefore, it is necessary for a passenger who needs to enter the authorized area to wait outside the hoistway corresponding to the hoistway in which the authorized area can be entered before taking the elevator. For multi-car parallel elevators, limited by the logic of the group control system, the allocation and waiting times of the cars on the hoistway may be long, resulting in long waiting times for the passengers.

Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

A car stopping method of an elevator system installed in a building, the elevator system comprising at least two vertical rails, at least one switching device and at least two self-driven cars smoothly switchable between the two rails via the switching device. At least two groups of hall doors are arranged in the building, at least two hall doors are arranged on each floor, the hall doors are connected with the elevator car on the track, and when the hall doors and the elevator car are opened, passengers can enter the elevator car. One of the landing doors of each floor together forms a set of landing doors, and each track engages a set of landing doors, i.e., a set of landing doors engages the same track, and the cars that passengers enter from the landing doors of different floors of the set of landing doors are located on one track. The multiple groups of hall doors are respectively connected with multiple tracks. The cars into which passengers enter from the plurality of groups of hoistway doors are on a plurality of different tracks, respectively.

In this scheme, when the track is equipped with many, can communicate between any two tracks, specifically, can communicate directly through switching device between any two tracks or through the switching device intercommunication between other tracks and other tracks between these two tracks.

All the hall doors of part of floors or part of the hall doors in part of floors are the hall doors of the authorized areas, namely, the passengers in the elevator car need to identify and select a certain floor or hall door in the authorized areas, the elevator car can stop at the selected floor or hall door in a flat way and open the elevator car door and the hall door, so that the passengers enter the authorized areas. The passenger in the car only needs to select the calling floor or the hall door, and the area which can be accessed without identity recognition is an unauthorized area.

And setting the call floor as a target floor and setting the call hall door as a target hall door. When a passenger selects a calling floor or a hall door in a car, the following two conditions exist:

1) Floor or hall door with calling floor or hall door as authorized area

If the passenger does not identify the floor or hall door before the passenger calls the floor or hall door in the selected mode, the control system is invalid according to the selected operation. If the passenger performs identity recognition on the selected call floor or hall door, the selected operation is effective.

For an efficient call floor selection operation, there are two cases:

i) The track where the elevator car sending the call signal is located is the same as the track corresponding to the destination floor or the destination hall door.

At this time, the car can continue to run to the destination floor or the destination hall door along the track where the car is located and then stop at the rear leveling floor, and when the track where the car is located is more congested, the car can be switched to other smooth tracks and finally switched back to the destination floor or the destination hall door and then stop at the rear leveling floor.

ii) the track where the elevator car which sends the call signal is located is different from the track corresponding to the target floor or the target hall door, and the elevator car is switched to the track corresponding to the target floor or the target hall door through the switching device to stop on the floor or the target hall door.

2) Floor or hall with hall door as unauthorized area

At this time, no matter whether the passengers in the lift car are identified or not, the selection of the call floor or the hall door is effective operation, and the control system controls the lift car to normally run to the target floor or the hall door after receiving the call instruction.

The method of operating the car signaling the call is referred to in the applicant's other patent applications and prior art.

It should be noted that, if the authorized area is provided with at least two groups of hall doors, that is, at least two hall doors are provided on each floor of the authorized area, and the effect of landing and opening of the car on any hall door of the same floor of the authorized area is the same for the passengers, for example, when the elevator is set for a plurality of hall doors of the same floor to share an elevator hall, only the passengers in the car need to select the floor to be reached, that is, the call floor, the car is stopped on any hall door of the selected floor, and the passengers can enter the same elevator hall. In contrast, if the landing and opening effects of the cars at different landing levels of the same floor are different, then when a passenger in the car selects, the arriving landing door needs to be selected, i.e. the landing door is called in.

The elevator car is internally provided with an identity recognition module, and after the call floor is selected, the elevator shaft selection in the leveling process is related to the recognition content of the identity recognition module.

The identity recognition module comprises one or more of fingerprint verification, two-dimensional code verification, mobile phone verification, iris verification, voice verification, magnetic card verification and the like.

The following is a description of two examples.

Example 1

Fig. 1 and 2 are schematic diagrams of an elevator of a building, said elevator comprising an unauthorized area F and an authorized area S. The unauthorized area F corresponds to three tracks, and the three tracks respectively correspond to three groups of hall doors, namely a hall door, a B hall door and a C hall door. The authorized area S is correspondingly provided with two tracks, and the two tracks respectively correspond to two groups of hall doors, namely a D hall door and an E hall door. The total five tracks of the unauthorized area F and the authorized area S are arranged in parallel and at intervals in the same plane.

Passengers enter the elevator car from a certain hall door of a certain floor of the unauthorized area F, and when the elevator car calls floors or the elevator doors in the elevator car are located in the unauthorized area F, the control system receives an elevator car calling instruction and then controls the elevator car to normally run to a target floor or the elevator door.

The passengers enter the car from a certain hall door of a certain floor of the unauthorized area F, when the calling floor or the calling hall door is positioned in the authorized area S, the passengers need to identify and reselect the floor or the hall door, otherwise, the control system is regarded as invalid operation. After the identity of the passenger is identified, the control system drives the car to switch from a certain track in the unauthorized area F to one of the tracks in the authorized area S, and the car stops at a destination floor or a destination hall door in a flat way.

The passengers enter the elevator car from a certain hall door of a certain floor of the authorized area S, and when the elevator car calls floors or hall doors in the elevator car are located in the unauthorized area F, the control system receives an elevator car calling instruction and then controls the elevator car to normally run to a target floor or hall door.

Passengers enter the car from a certain hall door of a certain floor of the authorized area S, and when the calling floor or the calling hall door is positioned in the authorized area S, the elevator car is optionally provided with: the area at the time of entry is S1, the area to be reached is S2, and the rights of S1 and S2 may be different from each other, including, parallel, or the like. If the authority of S1 is greater than that of S2 or the authority of S2 is the same, the person entering the car from S1 can directly enter S2 without identity recognition. If the authority of S1 is smaller than that of S2, or is a completely different authority, then entering the car from S1 wants to reach S2 still requires the authority at S2.

Example two

In this embodiment, as shown in fig. 3, five tracks are arranged in parallel and spaced in the same plane in the building.

In this embodiment, the car is provided with two openable car doors, the two car doors are arranged opposite to each other, and the two car doors are respectively a front car door and a rear car door. Correspondingly, part of the hall doors are arranged to be opened at two sides to match with two car doors of the car parked at the flat floor. The two openable side hall doors are respectively a front hall door and a rear hall door, the front hall door is matched with the front car door, and the rear hall door is matched with the rear car door. Preferably, the front hall door corresponds to the unauthorized area F, and the rear hall door corresponds to the authorized area S, i.e. passengers can enter the unauthorized area F from the opened front car door and the front hall door, and enter the authorized area S from the opened rear car door and the rear hall door.

As shown in fig. 3, an elevator schematic of a floor of a building is shown, and five tracks are provided, wherein five hall doors and two rear hall doors are provided, all the hall doors of the floor correspond to an unauthorized area F, and the two rear hall doors correspond to an authorized area S.

When passengers enter the elevator car from the front hall door of the unauthorized area F of a certain floor, the elevator car is called in by the elevator car, and the elevator car is called in by the elevator car, so that identity identification is not needed, and the elevator car is controlled to normally run to the target floor after the elevator car is called in by the control system.

When a passenger enters the car from the front hall door of the unauthorized area F of a certain floor, the inner calling hall door is the rear hall door of other floors, namely, when the passenger needs to enter the authorized area S, the passenger needs to identify and select the inner calling hall door, and the control system can control the car to move to the destination floor to open the rear car door and the rear hall door after the floor is stopped. If the passenger does not perform identity recognition and directly selects the call floor or the hall door, the control system judges that the operation is invalid.

When passengers enter the elevator car from the rear hall door of the authorized area S of a certain floor, the elevator car is called in as the front hall door of other floors, identity identification is not needed, and the control system controls the elevator car to normally run to the target floor after receiving the call in command, and then the front hall door and the front elevator door are opened.

When a passenger enters the car from the rear hall door of the authorized area S of a certain floor, and the inner calling hall door is the rear hall door of other floors, the passenger needs to identify and select the inner calling hall door first, and the control system can control the car to move to the destination floor to open the rear car door and the rear hall door after the landing. If the passenger does not perform identity recognition and directly selects the call floor or the hall door, the control system judges that the operation is invalid.

Finally, what is necessary here is: the above embodiments are only for further detailed description of the technical solutions of the present invention, and should not be construed as limiting the scope of the present invention, and some insubstantial modifications and adjustments made by those skilled in the art from the above description of the present invention are all within the scope of the present invention.
