Description

An embodiment of the present invention relates to an elevator device that can be managed in groups and a control method thereof.

In recent years, a plurality of elevators have been installed in a corner of a large building such as a department store, and an elevator system for group management of the elevators has been put into practical use.

In such an elevator system, an elevator having a full-passage operation function has been proposed.

The crowded passing operation function ignores (invalidates) the landing call registration on the floor on the way where there are no passengers and allows the passenger to pass through the floor when the passenger car is full. Then, by managing the operation of a plurality of elevators so that another car can be landed on the floor, the convenience of the user and the efficiency of the operation are improved.

Japanese Unexamined Patent Publication No. 2019-38683

However, conventionally, the total load in the car is detected, and when the total load exceeds the specified full value (for example, the full weight in the car), it is determined to be full. Therefore, for example, if users are riding in a biased situation near the entrance / exit of the car, the landing door (hall door) will not be boarded by the users on the floor that have landed due to the landing call registration, even though it is not full. Was sometimes closed, which was inefficient.

That is, if the user does not get on and off even though he / she has landed due to the landing call registration, the car during the ascending / descending operation is unnecessarily stopped, which is a factor of lowering the operation efficiency.

An embodiment of the present invention provides an elevator device and a control method thereof, which can prevent a car from being unnecessarily stopped during ascending / descending operation and can improve user convenience and operation efficiency. With the goal.

One embodiment of the present invention is an elevator device capable of group management by a group management device, which is provided in a corner of a building and is arranged for each floor and a car that is moved up and down between floors. A landing calling operation unit for landing the vehicle on the floor, a load detection unit for detecting the load value in the vehicle, and a photograph taken in the vehicle, which is arranged in the vehicle and photographed inside the vehicle. To stop the car on the floor that is going to be stopped next in response to the operation of the unit, the guide unit that guides the user in the car to get on and off, and the landing call operation unit. As a result of determining the congestion status in the car from the load value detected by the load detection unit at the landing operation start position where the flooring operation is possible, if the vehicle is not full, the photographed image taken by the imaging unit is used. When the congestion status in the car is judged and it is determined that the car is congested near the entrance / exit, the guidance unit provides guidance for alleviating the congestion near the entrance / exit, and the guidance is provided. When the congestion near the entrance / exit is not alleviated even if the above is performed, a control unit for invalidating the landing operation of the car on the floor on which the landing call operation unit is operated is provided. do.

Further, one embodiment of the present invention is a method of controlling an elevator device, in which the control unit stops the car on the floor to be stopped next in response to the operation of the landing call operation unit. By the time the car reaches the landing operation start position where it can be made, the congestion status in the car is determined from the load value detected by the load detection unit, and if it is not full, When the congestion status in the car is determined from the captured image taken by the photographing unit and it is determined that the vehicle is congested near the entrance / exit of the car, the guide unit determines the congestion in the vicinity of the entrance / exit. If the congestion near the doorway is not alleviated even if the guidance is given, the landing operation of the car on the floor where the landing call operation unit is operated is invalidated. It is characterized by doing.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, the same parts or related parts are designated by the same or similar reference numerals, and detailed description thereof will be omitted.

(One Embodiment)
FIG. 1 schematically shows the configuration of an elevator system 1 to which the elevator device according to the embodiment is applied. Here, three elevator devices En (also referred to as three or three) installed in a corner of a building having a plurality of floors are managed as a group by the group management device 50 in group units. The case where is set is illustrated.

That is, the elevator system 1 according to this embodiment includes, for example, three elevator devices En (first elevator E1, second elevator E2, third elevator E3) and a group management device 50. It is said that.

The first elevator E1 has a car 6-1 that is moved up and down between each floor of the building, which will be described in detail later. A balance weight 7-1, a first elevator control device (control unit) 10-1 and the like are connected to the car 6-1. Further, the car 6-1 is provided with an internal camera (photographing unit) 15-1 and a load detecting unit 16-1.

Then, in the hall (landing area) on each floor where the car 6-1 is moved up and down, the landing operation panel (landing call operation unit) 21-1 for landing the car 6-1 on the landing. Etc. are arranged. The operation signal (landing call signal) of the landing operation panel 21-1 is sent to the first elevator control device 10-1 and the group management device 50 by, for example, wired or wireless communication.

The second elevator E2 also has a car 6-2 that is moved up and down between each floor of the building. A balance weight 7-2, a second elevator control device (control unit) 10-2, and the like are connected to the car 6-2. Further, the car 6-2 is provided with an internal camera (photographing unit) 15-2, a load detecting unit 16-2, and the like.

Then, at the landing on each floor where the car 6-2 is moved up and down, a landing operation panel (landing call operation unit) 21-2 for landing the car 6-2 on the landing is arranged. Has been done. The operation signal (landing call signal) of the landing operation panel 21-2 is sent to the second elevator control device 10-2 and the group management device 50 by, for example, wired or wireless communication.

Similarly, the third elevator E3 has a car 6-3 that is moved up and down between each floor of the building. A balance weight 7-3, a third elevator control device (control unit) 10-3, and the like are connected to the car 6-3. Further, the car 6-3 is provided with an internal camera (photographing unit) 15-3, a load detecting unit 16-3, and the like.

Then, at the landing on each floor where the car 6-3 is moved up and down, a landing operation panel (landing call operation unit) 21-3 for landing the car 6-3 on the landing is arranged. Has been done. The operation signal (landing call signal) of the landing operation panel 21-3 is sent to the third elevator control device 10-3 and the group management device 50 by, for example, wired or wireless communication.

The landing operation panels 21-1, 21-2, and 21-3 are not limited to those provided for each unit, and may be shared by a plurality of units.

The group management device 50 is connected to the first elevator control device 10-1, the second elevator control device 10-2, and the third elevator control device 10-3, respectively, and is connected to the first elevator E1, the second elevator E2, The third elevator E3 is grouped and managed in group units.

The group management device 50 realizes the full-passage operation function of the elevator system 1. That is, during the ascending / descending operation, the users pass through the packed car 6-1, 6-2, 6-3 without responding to the landing call on the floor in the middle where there are no descendants. Let me. In this way, another car that is not full is landed on the floor where the landing call is registered, and a full-passing operation is performed so that the full car is not landed on the floor where the landing call is registered. It is designed for the convenience of people and the efficiency of operation.

In particular, even if the total load value in the car does not exceed the specified full weight (specified full value) and the car is not judged to be full, for example, the user may ride in a situation where the passengers are biased near the entrance / exit of the car. If this is the case, have the car perform a full-pass operation. As a result, even if the user on the floor that has landed due to the landing call registration cannot board the vehicle due to the user near the doorway, the car during the ascending / descending operation can be stopped (landed) unnecessarily. Therefore, problems such as a decrease in operation efficiency can be solved.

Here, with reference to FIG. 2, the configurations of the first elevator E1, the second elevator E2, and the third elevator E3 will be described more specifically by exemplifying the elevator device En.

That is, the first elevator E1, the second elevator E2, and the elevator device En, which is the third elevator E3, are general elevators that the users of the building mainly get on and off, as shown in FIG. 2, for example.

In this elevator device En, the main rope 14 is hung on the hoisting machine 13 arranged in the machine room 12 above the hoistway 11, the car 6 is hung on one end of the rope 14, and the balance weight is on the other end of the rope 14. 7 are suspended in a hanging manner.

The car 6 is arranged to face all the hall doors 22a, 22b, ..., 22n of the landings 20a, 20b, ..., 20n on each floor, and opens and closes together with the hall doors 22a, 22b, ..., 22n. It has a door 17. Then, for example, in the vicinity of the car door 17, an in-car operation panel 40 is provided for a user who is a passenger to perform a car calling operation for designating a destination floor (destination floor).

As shown in FIG. 3, the operation panel 40 in the car is provided with an open button 41a, a close button 41b, a destination floor button 42, a speaker (guide unit) 45, a display 46, and the like. The open button 41a and the close button 41b are used when opening and closing the car door 17. The destination floor button 42 is used to specify the destination floor. The speaker 45 is used when performing voice guidance. The display 46 is for displaying the arrival floor (destination floor) and the like.

Further, for example, as shown in FIG. 2, the car 6 has an internal camera (photographing unit) 15 for photographing the inside and grasping the congestion status of the users of the car 6, and the weights of all the users. A load detection unit 16 or the like for detecting (total load value) is provided. The internal camera 15 is provided, for example, on the ceiling portion of the car 6, and is capable of acquiring a captured image which is a camera image in the vicinity of the entrance / exit (car door 17) of the car 6.

The output of the internal camera 15 and the output of the load detector 16 are sent to the elevator control device 10 wirelessly or via the tail code 3.

Hall doors 22a, 22b, ..., 22n are provided on each floor for each of the landings 20a, 20b, ..., 20n. In the vicinity of the hall doors 22a, 22b, ..., 22n, there are landing operation panels (landing calling operation units) 21a, 21b, ..., 21n and a car for the user to perform a landing calling operation for designating the destination direction. A notification lamp (not shown) for notifying the arrival of No. 6 is provided.

On the other hand, in the machine room 12, in addition to the hoisting machine 13, an elevator control device 10 connected to the car 6 via a tail cord 3 is arranged. The elevator control device 10 includes, for example, an operation control unit 30, a user detection unit 33, a display control unit 35, a voice guidance unit 37, and the like.

The voice guidance unit 37 is controlled by, for example, the operation control unit 30, and outputs various voice guidances emitted from the speaker 45 of the operation panel 40 in the car.

The display control unit 35 is controlled by, for example, the operation control unit 30, and outputs various guides displayed on the display 46 of the operation panel 40 in the car.

The user detection unit 33 provides the operation control unit 30 with an output (total load value) of the load detection unit 16 for determining the state of congestion in the car 6. Further, the user detection unit 33 has come to provide the operation control unit 30 with an image taken by the internal camera 15 for determining the state of congestion in the car 6, especially in the vicinity of the doorway. There is.

Although none of the operation control units 30 is shown, the operation control unit 30 includes, for example, a registration unit for landing call registration and car call registration, a storage unit for storing a specified full value, and the like. Then, under the control of the group management device 50, the hoisting machine 13, the display control unit 35, the voice guidance unit 37, and the car door are operated based on the operations of the in-car operation panel 40 and the landing operation panels 21a, 21b, ..., 21n. 17 and the like are controlled to perform ascending / descending operation (operation control) of the car 6.

Further, the operation control unit 30 compares the output (total load value) of the user detection unit 33 with the specified full load value, and determines whether or not the inside of the car 6 is full by the user.

Further, the operation control unit 30 analyzes the output (camera image) of the user detection unit 33, and determines the state of congestion in the car 6, especially in the vicinity of the entrance / exit of the user.

When determining the congestion situation, it is desirable to consider not only the load but also the space (occupied area) occupied by luggage, carts, strollers, wheelchairs, etc.

Then, although the details will be described later, the operation control unit 30 outputs the result of the determination of the congestion status to the group management device 50, and executes the full-pass operation as necessary.

Next, the operation of the elevator system 1 according to this one embodiment, particularly the crowded passing operation at the time of calling the landing, will be described with reference to the flowchart of FIG.

First, while the elevator device En is being moved up and down toward the nearest destination floor, the landing operation panels 21a, 21b, ..., 21n on any floor up to the destination floor are operated to perform "landing call". Suppose.

Then, in the group management device 50, an elevator device En having the shortest arrival time (response time until landing) to the floor where the landing call was made and the direction of movement is the same is selected, and the elevator control device is selected. An instruction signal for registering the landing call is output to 10.

As a result, the corresponding elevator control device 10 registers the landing call in the operation control unit 30, for example, and determines whether or not the inside of the car 6 is full of users (step S1).

For example, after the car door 17 is closed, the operation control unit 30 determines that the load detection unit 16 from the user detection unit 33 is full when the output of the load detection unit 16 reaches the specified full value (YES in step S1), and the group Notify the management device 50 to that effect (full).

In addition to this notification, for example, at the landing operation start position (described later), the previous landing call registration is ignored (invalidated), and the hoisting machine 13, the display control unit 35, the voice guidance unit 37, and the like are controlled. Then, a full-pass operation is performed in which the car 6 passes through the floor where the landing call was made (step S2).

That is, in the elevator device En, when the nominal floor determined from the landing call is not the top floor, the reference floor (for example, the first floor), or the destination floor designated by the car call operation by the destination floor button 42, the elevator device En is set to the nominal floor. It is controlled to perform a packed passing operation without stopping the packed car 6.

Further, from the group management device 50, the elevator device En for landing on the floor where the landing call was made is reselected in place of the car 6 which is operated through the crowd, and the elevator control device for the elevator device En is reselected. An instruction signal for registering the landing call is output to 10. In other words, the elevator device En, which is in the same direction of movement and is not full, will arrive at the call floor where the landing call was made, next to the car 6 that is driven through the crowd, and will perform the landing operation. Newly selected as a candidate for car 6.

On the other hand, when the output of the load detection unit 16 does not reach the specified full value, the operation control unit 30 of the elevator control device 10 determines that the car 6 is not full (NO in step S1).

Next, the operation control unit 30 analyzes, for example, the output of the internal camera 15 from the user detection unit 33 (step S10), and determines the state of congestion near the entrance / exit of the car 6 (step S11).

Then, when it is not possible to confirm the congestion near the entrance / exit of the car 6 (NO in step S11), the hoisting machine 13, the display control unit 35, the voice guidance unit 37, and the like are controlled to call the landing. The car 6 is moved so as to land on the damaged floor (step S3).

In this way, when the normal ascending / descending operation is performed and the car 6 lands on the floor where the landing call is made (YES in step S4), the operation control unit 30 of the elevator control device 10 opens the car door 17. The door is opened (step S5), and the user gets on and off for a predetermined time.

When a predetermined time elapses or the close button 41b of the in-car operation panel 40 is operated within a predetermined time (YES in step S6), the operation control unit 30 of the elevator control device 10 moves the car door. 17 is closed (step S7). Then, the hoisting machine 13, the display control unit 35, the voice guidance unit 37, and the like are controlled to perform normal ascending / descending operation (step S8), and are designated by, for example, the destination floor button 42 of the in-car operation panel 40. Move the car 6 to land on the destination floor (destination floor).

On the other hand, in the above, when the operation control unit 30 of the elevator control device 10 confirms the congestion near the entrance / exit of the car 6 from the camera image (YES in step S11), the process is shifted to step S2. Then, the above-mentioned full-pass operation is performed.

That is, when the existence of many users is confirmed near the entrance / exit of the car 6, for example, the landing call registration for the car 6 is invalidated, and the full-pass operation is performed so that the car passes through the corresponding floor. It has become.

For example, if the passengers are riding in the car 6 in a particularly biased manner near the doorway, the users near the doorway will be an obstacle even though the car is not full, and the floor will be landed by the landing call registration. There are cases where the user cannot board. Even in such a case, the car 6 during the ascending / descending operation is unnecessarily stopped, and the problem of lowering the operation efficiency can be solved.

In the elevator system 1 according to this one embodiment, as the elevator device En, for example, three elevators E1, E2, and E3 are managed as a group. Therefore, by landing another car 6 that is not full under the control of the group management device 50 on the floor that has been registered as a landing call, the convenience (convenience) of the user is not impaired. , It is possible to improve the efficiency of operation.

As described above, according to the elevator system 1 according to the embodiment, even if the elevator system 1 is not full, it is assumed that the users are riding in a biased state near the entrance / exit of the car 6 and the elevator is full. I am trying to drive. That is, the case where the congestion near the entrance / exit of the car 6 is read from the camera image of the internal camera 15 is added as one of the conditions for determining the full-passage operation. As a result, the useless landing (stop) operation of the car 6 can be reduced, and the operation efficiency can be improved.

(Other embodiments)
In the above-described embodiment, when the presence of many users is confirmed near the entrance / exit of the car 6, the car 6 passes through the floor registered as the landing call regardless of whether the car is full or not. The case where driving is performed has been described, but the present invention is not limited to this.

That is, although the existence of many users was confirmed near the entrance / exit of the car 6, if it was not full, for example, before landing on the floor where the landing call was registered, the speaker 45 said, "There are people who ride. .. Please pack it in the back. ] And other voice guidance (announcements) may be provided.

Then, for example, in step S11 of FIG. 4, the user is notified from the front of the door by the announcement until the landing operation start position where the car 6 can be safely stopped on the floor where the landing call operation is performed. If it is confirmed that the congestion in the vicinity of the entrance / exit of the car 6 has been alleviated, the crowded passing operation may be canceled.

That is, in order to land the car 6 on the floor where the landing call operation is performed, for example, the car 6 is placed at the hoistway position (landing operation start position) where deceleration for stopping is started from the rated speed. Allow the announcement to be repeated until it is reached. Then, if it cannot be confirmed from the camera image of the hoistway position that the congestion near the entrance / exit of the car 6 has been alleviated based on the result of this announcement, the landing operation is invalidated and the crowded passage operation is performed.

On the contrary, if it can be confirmed from the camera image of the hoistway position that the congestion near the entrance / exit of the car 6 has been alleviated, the landing operation is not invalidated, the crowded passage operation is canceled, and the landing call operation is performed. It is also possible to make the stopped operation on the damaged floor.

As a result, in this elevator system 1, the user can get on and off smoothly, and if the user does not get on and off even though he / she has landed by the landing call registration, the car 6 during the ascending / descending operation is wasted. It is possible to eliminate the inconvenience of having to stop the system.

The guidance for eliminating congestion is not limited to voice guidance, but can also be performed using the display 46, and may be used in combination with voice guidance.

In one embodiment and the other embodiment described above, the group management device 50 has a function of comparing the total load value with the specified full load value and determining whether or not the inside of the car 6 is full by the user. You may be prepared.

Further, the group management device 50 may be provided with a function of analyzing the camera image and confirming the state of congestion in the car 6, particularly in the vicinity of the entrance / exit of the user.

Further, although the elevator system 1 in which a plurality of elevators are group-managed has been described as an example, the present invention is not limited to this, and the present invention can be applied to a case where one elevator device En is installed.

In addition, when calling the boarding area, the number of users in the hall can be detected, and the number of users trying to board the car 6 and the number of users in the car 6 can be used to get into the car 6. Compare with the possible number of people. Then, when all the users in the hall cannot get into the car 6, the above-mentioned full-pass operation may be performed.

Although some embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention.
