Description

Method for controlling elevator call signal and elevator system therefor}

The present invention relates to an elevator, and more particularly, to an elevator call signal control method and system for minimizing the inconvenience of passengers in using an elevator and improving the transportation efficiency of the elevator.

Elevators are indispensable for high-rise buildings, but these factors are taken into account because the state of riding inside the cages that rise and fall and the status of people waiting for boarding on the boarding stations of each floor vary. It is desirable to operate efficiently.

As a prior art relating to such an elevator, for example, a call button and a cancel button are installed in an elevator of an elevator, and a person riding in the kiln presses the call cancel button. The technique of canceling is proposed (refer patent document 1: Unexamined-Japanese-Patent No. 10-175780).

In addition, there is a technology in which a boarding point display device (boarding number display means) is installed at each boarding point of an elevator, and the number of passengers in the kiln is displayed on each boarding point (Patent Document 2: Japanese Patent Application Laid-Open No. 7-69553). Publication).

In the case of the technique of Patent Document 1, when a call button for a certain floor is pressed by a person riding in a cage, a person in the same cage releases the call with a call cancel button. If the cage's call button is pressed once, it stops at the calling floor, whatever the state inside the cage.

That is, once the call button of the cage is pressed at the boarding point side of each floor, even if the call cancel button is pressed inside the cage, the call stops at the called floor. Even if there are no people on the floor, there is an inefficient factor that the cage stops unconditionally.

In the case of the technique of Patent Document 2, a person waiting at the boarding station for the number of boarding passengers displayed on the boarding point display device (boarding number display unit) installed in the elevator boarding station shows how many people are in the garden over. Since only the call button of the cage is pressed once on the boarding point side of each floor, the inside of the cage stops at the call floor even when the cage is in a garden state. Turbulence, discomfort, and waiting time are caused to start again without being burnt, and the transportation efficiency of the elevator is reduced.

In addition, there may be a user who exits from the boarding area by recognizing that he / she cannot ride from the display contents of the boarding point display device (boarding number display means) at the elevator boarding area on each floor. In this case, the cage stops on the floor where no user is present, which also lowers the transportation efficiency of the elevator.

As described above, conventionally, as long as the call button is pressed even when there is no person in the elevator ride of each floor in the elevator operation, the elevator is unconditionally stopped at the floor where the elevator is called, and thus a passenger who has an emergency situation Or if the waiting people disappear after the floor calls, the passengers in the cage not only inconvenience, but also cause discomfort, there is a problem such as lowering the elevator transportation efficiency.

The present invention is to solve the above problems, when it is confirmed that there is no passengers on the floor calling the elevator, the cage may be passed through the control of the passengers without stopping on the calling floor, by using the elevator The present invention relates to an elevator call signal control method and apparatus for reducing the inconvenience of passengers and improving the transportation efficiency of the elevator.

If it is detected that there is no waiting, this is indicated by changing the state of the corresponding stop layer button in the cage, and the cage passes through the stop layer without stopping as the passenger inside the cage presses the corresponding stop layer button which has changed state. And control means (10) for controlling the elevating mechanism (8).

More specifically, the elevator system of the present invention includes a memory 4 in which a state table 20 of an elevator is stored, and message indicators 6a and 6b as guide means. 6c, the stop layer button 7 inside the cage, the cage elevating mechanism 8, the call buttons 9a, 9b and 9c whether they are installed on the wall of the platform of each floor, and control such equipment. It includes a control means 10 to.

The lifting mechanism 8 raises and lowers the cage. For example, as a device composed of a motor, a pulley, cables, and the like, the lifting movement is controlled by the control means 10.

The elevator boarding stations on each floor are provided with heat sensors 1a, 1b and 1c, and the heat sensors 1a, 1b and 1c are call buttons 9a and 9b on the floor. It is activated by pressing 9c.

In addition, the elevator system of the present invention includes a door opening and closing sensor (2), and a door opening and closing mechanism (3) for opening and closing the door of the cage.

The door opening / closing mechanism 3 is a device for opening and closing a door of a cage, and is composed of a motor, an actuator, and the like, which drive the door. 10) the opening and closing operation is controlled.

On the other hand, the door opening and closing sensor (2) finds that the cage door (door) is opened or closed by the door opening and closing mechanism and notifies the control means (10).

The memory 4 has a pressed state of a stop layer button 7 provided inside a cage, a pressed state of cage call buttons 9a, 9b and 9c on each stop layer, and a thermal sensor 1a. (1b) and (1c) is a device capable of storing information on board waiting status of each call floor.

The message indicators 6a, 6b and 6c are provided above the door opening and closing part of the elevator platform of each floor. The message indicators 6a, 6b and 6c are also controlled by the control means 10 and display messages such as the cage stopping or passing through the floor.

The stop layer button 7 inside the cage is provided with a count for the user's boarding or the wall surface inside the cage. The stop floor button 7 inside the cage is connected to the control device as a button for designating the stop floor for the passenger to designate the stop floor of the cage.

The cage call buttons 9a, 9b and 9c are provided on the walls of the elevator boarding stations on each floor, and are connected to the control device by buttons for waiting for boarding to stop the cage on the floor. .

The cage call buttons 9a, 9b, and 9c are composed of buttons indicating upward direction and buttons indicating downward direction, and each button is provided with a lamp. The lamp is turned off by being pressed.

On the other hand, the control means 10 is to process the signal detected by the heat detection sensor (1a) (1b) (1c) capable of detecting the presence or absence of waiting information of each call floor, the memory 4 (memory) It serves as an updating means for updating the information. For example, the control device updates the information in the state table 20 of the cage call floor of the memory 4 according to whether the boarding waiter is detected.

Then, the control means 10, when the information is updated that the detection result by the heat detection sensors (1a) (1b) (1c) of the call floor corresponding to that there is no waiting person, the corresponding stop floor button in the cage By changing the color of (7), you can cancel the call of the floor to help you choose whether to pass.

The elevator call signal control process by the elevator system of the present invention configured as described above is as follows.

For the sake of understanding, it is assumed that the elevator is called on the 30th floor of a 30-story building and the passenger goes down to the first floor while inside the cage.

First, when the passenger completes the boarding on the 30th floor and selects the first floor as the stop floor by using the stop floor button, the cage door is closed and the cage lifting mechanism 8 is operated to start the descending operation of the elevator.

At this time, if the call button on the 10th floor is pressed while passing the 19th floor, the call button provided on the 10th floor platform will be lit, but the corresponding stop floor button inside the cage will be lit. The stop layer button 7 inside the cage has a red light when the inside passenger is pressed, and a green light when the external call button is pressed (see FIG. 3).

On the other hand, since the elevator operation is made, the control means 10 continuously determines whether the cage call buttons 9a, 9b, 9c provided in the platform of each floor for the elevator boarding are pressed. Accordingly, when it is determined that there is a cage call on the 10th floor as a result of the determination by the control means 10, the detection of whether or not there is a boarding waiter on the platform of the 10th floor where the cage call button is pressed is immediately detected. Is started by the operation of.

The thermal sensors 1a, 1b, and 1c are sensors for detecting the presence of a person waiting for boarding by sensing a body temperature of a person.

As a result of the detection of the thermal sensors 1a, 1b and 1c, if no waiting person is detected in the platform on the 10th floor where the cage call buttons 9a, 9b and 9c are pressed, a predetermined time is counted. If a detection result indicates that there is no waiting person for a certain time, the passenger is notified of the inside of the cage.

At this time, the absence of a boarding waiter on the floor in which the cage is called may be notified by changing the lighting color of the corresponding stop floor button 7 inside the cage. That is, as shown in Figure 3, by changing the lighting color of the stop button 7, which was green to yellow to inform the occupants inside the cage.

Accordingly, in the present invention, if the passenger inside the cage wants to pass through, for example, without stopping at the tenth floor where no passengers are waiting, the stop floor button on the tenth floor, which is the stop floor, which is turned yellow, is applied. The elevator call to the platform is canceled.

When canceling the call of the floor by the passenger inside the cage as described above, it is preferable to turn off the call button provided on the landing wall of the floor 10, the floor.

Contrary to the above, if the passenger inside the cage does not press the corresponding stop floor button on the 10th floor where there is no waiting for boarding after the call, or if there is still a boarding waiter on the 10th floor of the calling floor, the cage is on the 10th floor of the calling floor. When the door is opened and the door is opened, the detection of the presence of a waiting passenger is temporarily stopped, and the call button on the 10th floor of the corresponding floor is turned off.

In order to control the elevator call signal as described above, whether or not there is a boarding waiter in the platform of the floor on which the cage call buttons 9a, 9b and 9c are pressed is determined by the thermal sensors 1a and 1b installed on the floor. It is preferably detected by 1c), but is not necessarily limited thereto. That is, whether there is a boarding waiter at the platform of the floor where the cage call buttons 9a, 9b, and 9c are pressed may be detected by processing image information obtained through a camera, which is an imaging device installed on the floor. This will be explained in more detail later.

On the other hand, informing the passenger inside the cage that there is no waiting person on the call floor, in addition to the lighting color change of the stop floor button 7 illustrated above, the flickering state is changed or waiting for boarding on a separate display window. Of course, it may display information that does not exist.

On the other hand, as another embodiment related to the detection of the waiting for boarding, unlike the above method for checking the waiting for boarding by the thermal sensors 1a, 1b, and 1c, cage call buttons 9a, 9b, and 9c. Whether or not there is a waiting person in the platform of the floor where) is pressed may be detected by processing image information of the boarding area photographed by a camera, which is an imaging apparatus installed in each floor.

As a technique for obtaining the number of people waiting for boarding from the image information on the elevator platform, so-called face recognition technology or the like may be used. In this case, the face recognition processing unit (not shown) may be placed inside or outside the control means 10. do.

When detecting waiting for boarding through the image processing, the memory 4 is pressed in the cage stop layer 7, the cage call buttons 9a, 9b, 9c in each stop layer, It functions as a storage device capable of storing the number of passengers waiting for the elevator for each floor detected by face recognition.

In this case, the control means 10 changes the color of the corresponding stop layer button 7 in the cage when the number of waiting persons of the call floor is updated to "0" by camera and face recognition technology. Will cancel the call to that layer to help you choose whether to pass.

Meanwhile, as another embodiment related to providing elevator call and cancellation information for a passenger inside a cage, information on whether a cage is called on each floor and information on whether a passenger is waiting for the corresponding stop floor is provided to the passenger inside the cage. As described above, instead of informing the status change of the lighting color of the stop floor button 7 through a change in the state, a separate display display window is provided inside the cage for information on whether the cage is called and the boarding for the stop floor. Of course, it can also provide information on the presence of waiting.

On the other hand, in the elevator call signal control method as described above, when the passenger inside the cage cancels the elevator call to the platform without a waiting person, pressing the corresponding stop layer button 7 again in the cage to the corresponding floor. The elevator call may be made again, and the state of the corresponding stop layer button 7 inside the cage may be returned to the state before the call cancellation.

At this time, if the call button (9a) (9b) (9c) provided in the platform of the floor is also automatically re-lighted, the boarding waiter returning to the platform of the floor of the call button (9a) (9b) (9c) It will save you the trouble of pressing again.

As described above, in the present invention, when it is confirmed that no passengers exist on the floor where the elevator is called, the cage can pass through the passengers without stopping at the calling floor by controlling the passengers. In addition to minimizing this, there is an effect to improve the transportation efficiency of the elevator, which is also the same when the elevator is going up, it is more effective when the building is a large or high floor.

On the other hand, the rights of the present invention is not limited to the embodiments described above, but defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self evident.
