Description

Technical Field

[0001] The present invention relates to an elevator system for guiding the state of an elevator to a passenger who plans to board.

Background Art

[0002] Generally, various buildings built for residential or business use are equipped with elevators, escalators, etc. to move people, goods, etc. in the vertical direction. In particular, the elevator is a typical vertical transportation means that has the advantage of being able to quickly move people, goods, etc. in the elevator car in high-rise buildings to the corresponding floor.

[0003] Such an elevator system generally includes an elevator car that moves passengers while moving vertically along a hoistway formed vertically inside the building with passengers on board, a motor unit that generates a predetermined power, a hoisting machine, etc., a mechanical unit that moves the elevator car to the corresponding floor by the button operation of the passengers, and an elevator control unit that controls the mechanical unit by the button operation of the passengers so that the elevator car can be smoothly and stably operated.

[0004] In a conventional elevator system, after the elevator door is opened, when a predetermined waiting time has elapsed or the door closing button is operated, the elevator door is closed. That is, even if all the passengers waiting to board have completed boarding the elevator, the elevator car departs after the elevator door closing waiting time has elapsed and the door is closed, or the passengers are required to operate the door closing button to shorten the door closing waiting time.

[0005] However, in such an additional operation of the door closing button, there is a problem of virus transmission between passengers due to button contact, and problems of aging and damage of the button due to frequent operation of the door closing button may occur.

[0006] On the other hand, each landing in an elevator system can be equipped with a display unit that shows the current floor and direction of ascent / descent of the elevator car. Such a display unit may also show various status information of the elevator, such as whether it is full, under inspection, malfunctioning, or abnormal.

[0007] However, conventional elevator systems typically display information about the elevator's status through text, meaning users can check the elevator's status after approaching the landing. Furthermore, even after approaching the landing, users who haven't checked the display may end up waiting for a long time even if the elevator is in a state where it's unusable due to inspection, malfunction, or other reasons. This presents a limitation.

[0008] To overcome these limitations, elevator systems have been developed in recent years that use voice output to inform elevator users at a greater distance of the elevator's status when it is unusable due to inspection, malfunction, or other reasons. However, since such voice guidance is continuously output until the situation preventing elevator use is resolved, there is a problem of noise generation.

[0009] Furthermore, conventional elevator systems have a problem in that even when the landing doors that are not connected to the elevator car are open due to elevator inspection or malfunction, they only communicate the elevator's status through the output of inspection or malfunction status information, which could lead to accidents such as falls for users who are unaware of this. [Overview of the Initiative] [Problems that the invention aims to solve]

[0010] The present invention aims to solve the problems of the prior art mentioned above, and the objective of the present invention is to provide convenience to elevator users by detecting, through a passenger detection sensor, that all passengers have boarded the elevator and automatically closing the elevator doors.

[0011] Another objective of the present invention is to provide an elevator system that provides voice guidance on elevator status, such as inspection, malfunction, abnormality, and overcrowding, and outputs voice guidance only when there is an object at the landing that is determined to be a passenger scheduled to board the elevator. [Means for solving the problem]

[0012] An elevator system according to one embodiment of the present invention includes an object detection sensor that detects an object within a sensing area of ​​the landing, and a passenger determination unit that determines whether the detected object is a passenger scheduled to board based on the object detection information from the object detection sensor.

[0013] In this embodiment, the elevator system may further include a door control unit that controls the opening or closing of the elevator doors based on the judgment of the passengers scheduled to board.

[0014] Furthermore, once the door control unit determines that the passengers scheduled to board the elevator have finished boarding, it can control the closing of the open elevator door without requiring the door closing input to be operated.

[0015] Furthermore, the door control unit can close the open elevator door when the number of scheduled passengers, which was one or more when the door was open, becomes zero.

[0016] Furthermore, the passenger determination unit may include a partitioning unit that divides the sensing area into two or more areas, including a waiting area around the boarding area doors and a surrounding area surrounding at least a part of the waiting area; an object tracking unit that tracks an object detected by the object detection sensor; an area determination unit that determines the area where the tracked object is located; a speed determination unit that determines the speed of movement of the tracked object; and a passenger determination unit that determines the tracked object to be a scheduled passenger if its speed decreases by a predetermined amount after the tracked object enters the waiting area from the surrounding area.

[0017] Furthermore, the passenger determination unit may further include a non-passenger determination unit that determines the tracked object to be a non-passenger passing through the boarding area if, after the tracked object enters the waiting area from the surrounding area, its speed does not decrease by more than a predetermined amount and the boarding area doors are closed.

[0018] On the other hand, an elevator system according to another embodiment of the present invention may further include a door control unit that controls the closing of the elevator doors based on the number of remaining passengers inside the elevator car.

[0019] In this case, the passenger determination unit may further include a partitioning unit that divides the sensing area into three or more areas, including a waiting area around the doors of the boarding area, a surrounding area surrounding at least a part of the waiting area, and a boarding / alighting area connecting the inside of the elevator car and the waiting area; an object tracking unit that tracks an object detected by the object detection sensor; an area determination unit that determines the area where the tracked object is located; a boarding passenger determination unit that determines the tracked object is a boarding passenger when it enters the alighting area from the waiting area; an alighting passenger determination unit that determines the tracked object is an alighting passenger when it enters the waiting area from the alighting area; and a remaining passenger determination unit that determines the number of remaining passengers based on the number of boarding passengers and the number of alighting passengers.

[0020] Furthermore, it can further include a state information generation unit that determines the state of the elevator and generates state information, a state information output unit that includes a voice output unit so as to be able to output the state information through voice guidance, and an output control unit that determines the presence or absence of the voice guidance output of the voice output unit based on the determination of the passengers scheduled to board.

[0021] In addition, when at least one of the objects sensed by the object sensing sensor is determined to be a passenger scheduled to board, the output control unit can control the voice output unit to output the voice guidance.

[0022] In addition, the state information may include at least one of inspection, failure, abnormality, and full capacity.

Advantages of the Invention

[0023] According to the present invention, after a person scheduled to board the elevator is sensed, the door is controlled to close while completing boarding the elevator, and when a person scheduled to board is sensed during door closing, an accident can be prevented by opening the elevator door.

[0024] In addition, the present invention guides the state of the elevator, such as inspection, failure, abnormality, and full capacity, through voice, and improves the convenience of use for users by outputting voice only when an object determined to be a person scheduled to board the elevator exists at the landing.

[0037] Furthermore, it should be noted that the attached drawings are intended to facilitate understanding of the concept of the present invention, and should not be interpreted as limiting the concept of the present invention.

[0038] The elevator system according to the present invention will be described in more detail below with reference to the attached drawings.

[0039] Figure 1 is a functional block diagram of an elevator system according to one embodiment of the present invention, and Figure 2 is a schematic diagram showing the appearance of a landing where the elevator system according to one embodiment of the present invention is applied.

[0040] In the following, an elevator system according to one embodiment of the present invention will be described in general terms with reference to Figures 1 and 2.

[0041] An elevator system according to one embodiment of the present invention is characterized by providing voice guidance on the elevator's status, such as inspection, malfunction, abnormality, or full capacity, and outputting voice guidance only when an object determined to be a passenger is present at the landing.

[0042] For this purpose, the elevator system according to this embodiment may be configured to include, as shown in Figure 1, a state information generation unit 100 that generates elevator state information, a state information output unit 200 that outputs elevator state information, a passenger detection sensor 300 that senses an object at the landing, a passenger determination unit 400 that determines whether or not the object is a passenger, and an output control unit 500 that controls the output of the state information output unit 200.

[0043] The status information generation unit 100 can determine the status of the elevator and generate status information. The status information generated by the status information generation unit 100 may include inspection, malfunction, abnormality, and full capacity.

[0044] Specifically, the status information generation unit 100 can determine the elevator's state as "inspection state" when the elevator operation mode is switched to "inspection mode" by the administrator's mode operation, and can determine the elevator's state as "abnormal state" when the elevator operation mode is switched to "abnormal mode" by the administrator's mode operation. Furthermore, the status information generation unit 100 can determine the elevator's state as "fault mode" when a malfunction is detected in the elevator or when the elevator operation mode is switched to "fault mode". In addition, the status information generation unit 100 can determine the elevator's state as "full" when the weight of passengers in the elevator car is measured to be equal to or greater than the standard weight (for example, 90% of the permissible passenger weight).

[0045] The status information output unit 200 outputs the status information generated by the status information generation unit 100 in various formats, enabling people planning to ride the elevator to check the elevator's status.

[0046] Referring to Figure 2, the status information output unit 200 may include a character output unit 210 that outputs status information through text guidance. The character output unit 210 is individually arranged for each floor of the landing and can output not only status information but also floor information of the elevator car's current position and information on the direction of ascent and descent.

[0047] Furthermore, the status information output unit 200 may include a voice output unit 230 that outputs status information through voice guidance. The voice output unit 230 may also be individually arranged for each floor of the landing together with the text output unit 210. In this way, the elevator system according to this embodiment can inform passengers who are further away about the elevator's status, such as inspection, malfunction, abnormality, or full capacity, through voice guidance.

[0048] The object detection sensor 300 may be placed on the landing to detect objects within the detection area a of the landing. In this case, the object detection sensor 300 may be placed individually on each floor of the landing, and preferably it may be placed on top of the JAMB of the landing.

[0049] While a radar sensor may be used as the object detection sensor 300, it is not limited to this, and various sensors that can detect objects within a predetermined range can be used as the object detection sensor 300. Preferably, a millimeter-wave (mmWave) radar sensor may be used as the object detection sensor 300 to improve the accuracy of object detection.

[0050] At this time, the object detected by the object detection sensor 300 may be a passenger who is scheduled to board the elevator, but it may also be a non-passenger passing through the detection area a of the landing, unrelated to the elevator. When the object detection sensor 300 detects an object, the passenger determination unit 400 can determine whether the object is a scheduled passenger or a non-passenger based on the detection information from the object detection sensor 300. The passenger determination unit 400 is located in the central control panel and can individually determine the number of scheduled passengers on each floor of the landing. A detailed explanation of how the passenger determination unit 400 determines whether an object is a scheduled passenger or a non-passenger will be provided later with reference to Figures 4 to 6. The passenger determination unit 400 can also determine the number of remaining passengers inside the elevator car based on the detection information from the object detection sensor 300, and a detailed explanation of this will be provided later with reference to Figures 8 to 10.

[0051] The output control unit 500 can determine and control whether or not the status information output unit 200 outputs status information. In this case, the output control unit 500 is located in a central control panel and can individually control the status information output unit 200 for each floor of the landing.

[0052] Specifically, when the status information generation unit 100 generates status information, the output control unit 500 can control the character output unit 210 to continuously output the status information generated by the status information generation unit 100. In this case, the output of status information by the character output unit 210 may continue until the state ends. On the other hand, the voice output unit 210 may not continuously output status information generated by the status information generation unit 100. Specifically, when the status information generation unit 100 generates status information, the output control unit 500 can determine whether or not to output status information from the voice output unit 210 based on the judgment of the passenger determination unit 400. Preferably, the output control unit 500 can control the voice output unit 230 so that voice guidance is output only at boarding areas on floors where the passenger determination unit 400 determines that there is at least one passenger scheduled to board.

[0053] Thus, the elevator system according to this embodiment can prevent noise from meaningless voice announcements by outputting voice only when there is an object at the landing that is determined to be a person scheduled to board the elevator.

[0054] Figure 3 is a flowchart showing the process of audio output of elevator status information in an elevator system according to one embodiment of the present invention.

[0055] The following describes the audio output process of the elevator system status information according to this embodiment, with reference to Figure 3.

[0056] When the status information generation unit 100 generates status information such as inspection, malfunction, abnormality, or full capacity (S100), the output control unit 500 can control the character output units 210 on each floor to output the status information in character form (S200).

[0057] The output control unit 500 then determines whether an object is detected by the object detection sensor 300 on each floor (S300), and if an object is detected (S300-Y), it can determine whether there is a floor that contains at least one passenger scheduled to board among the detected objects, based on the determination of the passenger determination unit 400 (S400).

[0058] If there is a floor among the detected objects that includes one or more passengers scheduled to board (S400-Y), the output control unit 500 can control the voice output unit 230 so that an announcement voice is output at the boarding area on that floor (S500).

[0059] On the other hand, if no object is detected (S300-N), or if no passengers are scheduled to board among the detected objects (S400-N), the announcement voice will not be output at the elevator landing on that floor, and object detection and determination of whether or not there are scheduled passengers will continue until the generated elevator state is completed.

[0060] Figure 4 is a functional block diagram showing the detailed configuration of the passenger determination unit according to one embodiment of the present invention, Figure 5 is a diagram showing the sensing area of ​​the landing in the elevator system according to one embodiment of the present invention, and Figure 6 is a diagram showing an example of scheduled passengers and non-passengers in the elevator system according to one embodiment of the present invention.

[0061] In the following section, with reference to Figures 4 to 6, the passenger determination unit 400 of the elevator system according to this embodiment will be described in more detail.

[0062] As described above, the passenger determination unit 400 can determine whether the object detected by the object detection sensor 300 is a passenger scheduled to board or a non-passenger. To this end, as shown in Figure 4, the passenger determination unit 400 may include a partitioning unit 410 for demarcating the detection area, an object tracking unit 420 for tracking the detected object, an area determination unit 430 for determining the area where the tracked object is located, a speed determination unit 440 for determining the speed of movement of the tracked object, a scheduled passenger determination unit 450 for determining whether the tracked object is a passenger scheduled to board, and a non-passenger determination unit 460 for determining whether the tracked object is a non-passenger.

[0063] The compartment 410 can partition the sensing area to include a waiting area where scheduled passengers primarily wait, and a surrounding area that is arranged to surround at least a portion of the waiting area.

[0064] Referring more specifically to Figure 5, the partition 410 can partition a predetermined area around the elevator door d into a waiting area a1, and partition a predetermined area surrounding the waiting area a1, excluding the elevator door d or the wall on the door d side, into a surrounding area a2. Preferably, the size of the waiting area a1 can be set to be proportional to the area inside the car, or it can be set to be proportional to the number of people the car can accommodate. Here, in Figure 5, the sensing area a and each partitioned area are rectangular in shape, but it is not limited to this, and the sensing area a and each partitioned area can be circular in shape.

[0065] The object tracking unit 420 can classify and track detected objects based on object detection information sensed from the object detection sensor 300. In other words, the object tracking unit 420 can identify objects sensed by the object detection sensor 300 and track the movement path of those objects by tracking the same objects.

[0066] The area determination unit 430 can determine the area where the tracked object tracked by the object tracking unit 420 is located, based on the area information of the area division unit 410. The speed determination unit 440 can determine the speed of the tracked object based on the tracking path of the tracked object over time.

[0067] The passenger determination unit 450, after receiving the area location of the tracked object from the area determination unit 430, determines the movement of the tracked object between areas, and after receiving the movement speed of the tracked object over time from the speed determination unit 440, determines the change in speed in each area. If the movement speed decreases by more than a certain threshold after the tracked object enters the waiting area from the surrounding area, the unit can determine that the object is a passenger scheduled to board.

[0068] Using Figure 6 as an example, the passenger determination unit 450 can determine that if both the first object u1 and the second object u2, detected by the object detection sensor 300, enter the waiting area a1 from the surrounding area a2, then if the first object u1 stops after entering the waiting area a1 with its movement speed decreasing by more than a certain threshold, and the second object u2 does not decrease in movement speed below a certain threshold after entering the waiting area a1, then the unit can determine that the first object u1 is a passenger scheduled to board, and the second object u2 is not a passenger scheduled to board.

[0069] The non-passenger determination unit 460, after receiving the area location of the tracked object from the area determination unit 430, determines the movement of the tracked object between areas, and after receiving the movement speed of the tracked object over time from the speed determination unit 440, determines the change in speed in each area. If the movement speed has not decreased by more than a certain amount after the tracked object enters the waiting area from the surrounding area, the unit can determine that the object is a non-passenger.

[0070] Using Figure 6 as an example, the non-passenger determination unit 460 can determine that even if both the first object u1 and the second object u2 detected by the object detection sensor 300 enter the waiting area a1 from the surrounding area a2, if the first object u1 stops after entering the waiting area a1 with its movement speed decreasing by more than a standard, and the second object u2 does not decrease in movement speed by more than a standard after entering the waiting area a1, then the second object u2 is determined to be a non-passenger, and the first object u1 is determined to be a non-passenger.

[0071] In addition to the above, the non-passenger determination unit 460 can determine that an object that has entered the surrounding area a2 is a non-passenger if it has stopped without entering the waiting area a1 or has moved outside the sensing area a.

[0072] In this case, with the elevator doors open, passengers scheduled to board can board the elevator without reducing their speed in the waiting area a1. Therefore, the passenger determination unit 450's determination of whether a passenger is scheduled to board, or the non-passenger determination unit 460's determination of whether a passenger is not, based on the passenger's movement speed, can be performed under conditions where the elevator doors are closed.

[0073] Preferably, the passenger determination unit 450 can determine that a person who entered the surrounding area a2 with the elevator doors open is a passenger, even if the person does not reduce their speed after entering the waiting area a1. Conversely, the non-passenger determination unit 460 may not determine that a person who entered the surrounding area a2 with the elevator doors open is a non-passenger, even if the person does not reduce their speed after entering the waiting area a1.

[0074] Figure 7 is a functional block diagram showing an additional configuration for door control in an elevator system according to one embodiment of the present invention; Figure 8 is a functional block diagram showing an additional configuration for a passenger determination unit for determining remaining passengers in an elevator system according to one embodiment of the present invention; Figure 9 is a diagram showing an example of a passenger boarding in an elevator system according to one embodiment of the present invention; and Figure 10 is a diagram showing an example of a passenger disembarking in an elevator system according to one embodiment of the present invention.

[0075] In the following, with reference to Figures 7 to 10, the configuration for controlling the doors based on the judgment of the passenger determination unit 400 in the elevator system according to this embodiment will be described.

[0076] The elevator system according to this embodiment is characterized in that, after the elevator doors open upon arrival at the landing, the system determines that all passengers scheduled to board at the landing have boarded, and then automatically closes the elevator doors after determining that all passengers inside the elevator car have disembarked and there are no remaining passengers inside the car.

[0077] For this purpose, the elevator system according to this embodiment includes a door control unit 600 that controls the opening or closing of the elevator door, and the door control unit 600 can control the closing of the elevator door based on sensing information from the passenger sensing sensor 300 or the judgment of the passenger determination unit 400.

[0078] The door control unit 600 can close the elevator door if the passenger detection sensor 300 on the floor where the elevator has stopped cannot detect a passenger in the detection area a. Specifically, when the elevator door is opened, the door control unit 600 waits for a set time from the moment the elevator door is fully open, and if the passenger detection sensor 300 does not detect a passenger, it can close the elevator door. In this case, the set time may be shorter than the time it takes for the elevator door to close automatically, and may be sufficient time for the first passenger to disembark from the elevator. For example, the set time may be 3 seconds.

[0079] Preferably, even if the passenger detection sensor 300 detects a passenger on the floor where the elevator has stopped, the door control unit 600 can close the elevator door if none of the detected passengers are determined to be scheduled passengers. Specifically, the door control unit 600 can close the elevator door when the number of scheduled passengers, which was one or more when the elevator door was open, becomes zero.

[0080] Thus, the elevator system according to this embodiment automatically closes the elevator doors after the doors have opened upon arrival at the landing and once all passengers have boarded. This eliminates the need for passengers to press a separate close button, thus preventing virus transmission through button contact. In this case, the elevator system according to this embodiment may also be equipped with a voice recognition system that allows passengers to call the elevator using their voice at the landing or to input their destination floor. In this case, since passengers do not need to touch any buttons during the entire process of using the elevator, virus transmission through button contact during elevator use can be completely prevented.

[0081] On the other hand, the door control unit 600 can control the closing of the elevator doors based on the number of remaining passengers inside the elevator car. Specifically, the door control unit 600 can control the closing of the elevator doors when the number of remaining passengers inside the elevator car is 0.

[0082] To this end, the passenger determination unit 400 may include, as shown in Figure 8, a passenger boarding determination unit 470 that determines passengers boarding the elevator, a passenger disembarking determination unit 480 that determines passengers disembarking from the elevator, and a passenger remaining determination unit 490 that determines the remaining passengers inside the elevator car. In this case, the area determination unit 430 of the passenger determination unit can partition the sensing area a to include not only the waiting area a1 and the surrounding area a2, but also the disembarking area a3. Here, the disembarking area a3 may be an area connecting the waiting area a1 and the inside of the elevator car c, as illustrated in the examples shown in Figures 9 to 10.

[0083] As illustrated in Figure 9, the passenger boarding determination unit 470 can determine that an object u3 tracked by the object tracking unit 420 is a boarding passenger if it enters the disembarking area a3 from the waiting area a1 with the elevator doors open. Then, as illustrated in Figure 10, the disembarking passenger determination unit 480 can determine that an object u4 tracked by the unit is a disembarking passenger if it enters the waiting area a1 from the disembarking area a3 with the elevator doors open.

[0084] The remaining passenger determination unit 490 can determine the number of remaining passengers inside the elevator car by comparing the number of passengers disembarking and boarding determined at each floor's landing. Specifically, the remaining passenger determination unit 490 can determine the number of remaining passengers by subtracting the sum of passengers disembarking from the sum of passengers boarding on all floors.

[0085] Thus, the present invention maximizes elevator operation efficiency by automatically closing the elevator doors after determining that all passengers have disembarked from the elevator car after the doors have opened upon arrival at the landing, and that there are no remaining passengers inside the car.

[0086] On the other hand, when the operating mode is normal mode, the door control unit 600 controls the opening or closing of the elevator doors based on the landing call input, door close button input, door open button input, the input destination floor, whether the elevator car has arrived at the landing, the door open time, etc. When the operating mode is switched to inspection mode or malfunction mode, the operation of the doors is controlled by an administrator's input operation using a separate administrator operation module. For example, when the operating mode is normal mode, the door control unit 600 automatically controls the closing of the open elevator doors after a set time has elapsed, but when the operating mode is inspection mode, even if a set time has elapsed, the open elevator doors may not be closed unless a closing input operation is performed through the administrator operation module.

[0087] In this embodiment, the door control unit 600 can immediately close the open elevator door at a landing when it detects a passenger scheduled to board, even if the operating mode is inspection or malfunction mode and no closing input operation is performed through the administrator operation module. Here, the elevator door includes the landing door and the car door, and if there is no elevator car at the landing, the door control unit 600 can close the landing door at that landing separately from the car door.

[0088] Therefore, the present invention can prevent accidents such as falls from occurring when a landing door that is not connected to the elevator car is left open due to elevator inspection or malfunction, and the user is unaware of this.

[0089] The above description is merely illustrative of the technical concept of the present invention, and a person with ordinary skill in the art to which the present invention pertains will be able to make various modifications and variations without departing from the essential characteristics of the present invention. Therefore, each embodiment disclosed herein is for illustrative purposes only, not to limit the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by such embodiments.
