Description

[0001] Apparatus for managing elevator [0002]

Elevator is a device that moves people and cargo up and down by using power. As society develops, elevator has become an essential means of transportation in high-rise buildings. Now, elevator is a convenient and safe service for passengers from simple passenger transportation As a means of providing. Especially, in a residential environment like a high-rise apartment, an elevator is used as a transportation means to be installed.

The elevator includes an input unit for receiving a button signal, a motor driving unit for moving the elevator up and down, a microcomputer for controlling the motor driving unit based on the input signal, and an output unit for displaying data transmitted from the microcomputer.

When the user presses the button on the 10th floor in the elevator, the microcomputer judges whether there is a waiting person waiting for the riding by inputting the stop button at the elevator stop of the second floor. If the stop button is inputted to the elevator stop The elevator is stopped and controlled on the third floor in order to board the waiting staff. However, when the stop button is not inputted to the elevator stand of the second floor, it is controlled to move to the third floor through the second floor. When passing through the third floor, it is similarly checked whether the stop button is inputted to the three-story elevator boarding stop, and the control is stopped at the third floor or the third floor is passed as it is.

However, even if the user suddenly leaves the stop button at the elevator stand at the stop, or the stop button is depressed due to the mischief of the child, the elevator stops, thereby causing power loss and troubles to the passenger.

To solve this problem, when the same button is repeatedly pressed, the inputted command is canceled. For example, if the stop button is pressed once on the elevator stop, the stop command is inputted. If the stop button is pressed once again, So that unnecessary elevator operation can be prevented.

However, in the related art in which the same button is repeatedly inputted and the command is canceled, unnecessary elevator operation can not be prevented if the user leaves the elevator stop without releasing the stop button or children deliberately play with the stop button.

Furthermore, in recent years, a smart elevator system is applied to a building in which a plurality of elevators are operated, so that even if one stop button of a plurality of elevators is depressed at the same time in an elevator hall of the same floor, only one elevator among a plurality of elevators is controlled to move to an elevator stand, It is possible to prevent the power consumption caused by moving all the elevators to the elevator stand. However, even in a case where a large number of passengers for boarding an elevator stop in a smart elevator system exists, there is a problem that a long time is required to wait for the passengers to move to a desired floor by controlling only one elevator among a plurality of elevators.

In addition, when a large number of waiting people waiting for an elevator exist in each floor and the passenger does not exceed the allowable occupant number of the elevator, But there is a problem that unnecessary power and time are wasted because the elevator stops repeatedly without riding in the elevator

Hereinafter, an elevator operation control apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a view for explaining an example of using an elevator according to the present invention.

Referring to FIG. 1, an elevator for operating each floor is installed in a building, and each floor is provided with an elevator boarding place where a user rides or drops an elevator. The user who wants to use the elevator is waiting at the elevator stop. When the elevator moves to the floor where the user is located, the elevator is boarded.

In the elevator stop, there is a static button 20 for requesting the user 30 to move the elevator to the elevator stop. The user 30 selects the up and down buttons among the stop buttons 20 to move to the upper floor or to move to the lower floor Enter the stop request command. When the elevator is moved to the floor, the elevator car door 10 is opened and the user 30 rides on the elevator to set the layer the user 30 wants to move by pressing the desired floor button.

If another user wants to use the elevator at the elevator stop of the floor located in the moving direction while the elevator is moving to the set floor, the elevator stops at the floor and moves to another floor after boarding another user.

The elevator operation control apparatus according to the present invention judges whether there is a waiting staff to use the elevator in the elevator boarding place or the number of waiting staff through the camera 111 installed in the elevator boarding station, Or whether the elevator is stopped regardless of the stop request signal based on the number of waiting persons present in the elevator stop.

2 is a functional block diagram for explaining an elevator operation control apparatus according to the present invention.

2, the judging unit 110 judges whether there is a waiting person waiting to ride the elevator at the elevator boarding place of each floor of the building. Meanwhile, the stop button 120 is disposed at an elevator stop in each floor of the building. A user who wishes to use the elevator inputs a stop request command of the elevator through the stop button 120 arranged at the elevator stop, do.

The riding control unit 140 determines whether or not there is an elevator bus stop in the floor where the elevator bus request command is input based on the determination result of the determination unit 110 and the presence of the elevator bus stop, The elevator stop request command is ignored and the stop request command is passed through the elevator stand where it is inputted.

Here, each component constituting the elevator operation control device transmits / receives data between each component via the communication interface 130, wherein the communication interface 130 is a wired communication interface for transmitting / receiving data between components, Interface may be used and is within the scope of the present invention.

On the other hand, the additional personnel calculation unit 170 measures the total weight of the riding passengers currently boarding the elevator, subtracts the total weight calculated on the allowable riding weight from the elevator, and calculates the number of people who can ride on the elevator. In order to measure the total weight of the riding persons currently boarding the elevator, the additional personnel calculation unit 170 includes a measuring unit for measuring the total weight of the current elevator on which the riding personnel boarded, and subtracts the total weight from the allowable riding weight of the elevator To calculate the deduction weight. The additional personnel calculation unit 170 calculates the number of persons who can be additionally mounted on the elevator based on the deduction weight. Herein, the additional person calculation unit 170 may calculate the number of additional persons who can be additionally boarded by dividing the deduction weight by the average weight of a general adult.

When a plurality of elevators are operated on the building, the operation control unit 160 controls the number of the elevators to be elevated based on the number of the waiting staff existing in the elevator boarding place and the number of the additional boarding passengers Of the elevator. That is, in the conventional smart elevator system, a plurality of elevators are operated. In accordance with the stop request command, only one elevator of the plurality of elevators is controlled to move to the floor where the stop request command is inputted. However, according to the elevator operation control apparatus of the present invention, the number of additional passengers is greater than the number of passengers on the basis of the number of the waiting passengers present in the elevator passenger compartment and the number of passengers who can move on the elevator The elevator is moved to the floor where the stop request command is inputted to help the waiting staff to wait for the elevator and to reduce the waiting time. For example, one elevator having the number of additional passengers is larger than the number of passengers is selected to control the movement to the floor where the stop request command is inputted, or a plurality of elevators are selected so that the sum of the number of the additional passengers of each elevator is larger than the number of passengers And controls movement to the layer where the stop request command is inputted.

The elevator operation control apparatus according to the present invention further includes a high speed button 150. When a user on the inside of the elevator inputs a pass command through the high speed button 150 provided in the elevator, The control unit 140 compares the total weight of the passengers riding the elevator with the critical weight, and when the total weight exceeds the critical weight and the pass command is inputted through the high speed button 150, the control unit 140 ignores the elevator stop request command, And passes through the elevator seat to the floor set by the user who boarded the inside. Therefore, when the passenger is not allowed to ride the passenger even if the passenger does not exceed the allowable passenger number of the current elevator, the high speed button is used to prevent the elevator from stopping at the passenger ship repeatedly without additional riding, thereby preventing unnecessary power and time from being wasted.

FIG. 3 is a functional block diagram for explaining the determination unit according to the present invention in more detail.

Referring to FIG. 3, the camera unit 111 is installed in an elevator stand to photograph an image of an elevator stop, and the detector 113 extracts a face of the person from the image and waits for the elevator to board the elevator Detects the waiting staff. In order to extract a human face from the photographed image, the detection unit 113 first generates an object image by removing the background image from the photographed image, divides the region corresponding to the feature of the human face in the object image, Detect personnel. Various face extraction schemes may be used depending on the field to which the present invention is applied, and this is within the scope of the present invention.

The wait staff determination unit 115 determines whether there is a wait staff at the elevator stand based on the detected wait staff or the number of wait staff present at the elevator stand.

4 is a flowchart illustrating an elevator cruise control method according to the present invention.

4, it is determined whether a stop request command of the elevator is inputted through the stop button disposed at the elevator stop (S110). When the stop request command is input, if the elevator is moved close to the elevator stop, it is determined whether there is a wait staff at the elevator stop (S130).

When the elevator stops at the elevator boarding place when the stop request command is inputted, if there is a waiting staff at the elevator boarding place, it is determined whether the total weight of the people aboard the elevator exceeds the critical weight (S150). Wherein the critical weight is less than the allowable ride weight of the elevator and the difference weight between the allowable ride weight and the critical weight is less than the average weight of one adult. If the total weight of the passengers on the elevator exceeds the critical weight, it is determined whether a pass command is inputted through the high-speed button disposed inside the elevator (S170).

When the total weight of the passengers on the elevator exceeds the critical weight and the pass command is inputted through the high speed button disposed in the elevator, the passenger can ignore the stop request command inputted from the elevator stop, (S190).

However, if there is no waiting staff at the elevator stop (S140), the stop request command is passed without stopping the elevator stop.

5 is a flowchart for explaining an example of a method of controlling the operation of an elevator when a plurality of elevators are operated on a building.

5, the total weight of the riding passengers currently on the elevator is measured (S210), the total weight is subtracted from the allowable riding weight of the elevator, and the number of additional riding passengers is calculated (S230) .

The number of waiting staff waiting for the elevator to board the elevator bus is judged by the judging unit, and the number of waiting staff is compared with the number of additional busers (S250). If the number of waiting staff moves to the elevator bus stop, If the number of persons is greater than the number of persons, the elevator is controlled to move to the elevator boarding place, or an elevator having more people than the number of persons to be boarded is selected and moved to the elevator boarding place (S270).

For example, if the number of passengers present in the three-story elevator bus stop is six and the number of additional passengers who can move from the sixth floor to the first floor is four, then the first elevator passes through the three- . On the other hand, the second elevator, which is currently moving from the seventh floor to the first floor, can be stopped and controlled on the third floor.

As another example, it is assumed that the number of passengers present in the three-story elevator bus stop is six, the number of passengers who can move on from the sixth floor to the first floor is four, When the number of persons who can ride the elevator is three, both the first elevator and the second elevator can be stopped and controlled in three layers.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
