Description

elevator system

[0001] The present invention relates to an elevator system that provides information on the status of an elevator to a passenger.

[0002] In general, elevators and escalators are installed in various buildings constructed for residential or commercial purposes to move people or objects vertically. In particular, elevators are a representative vertical means of transportation in high-rise buildings that have the advantage of quickly moving people or objects inside the elevator car to the appropriate floor.

[0003] These elevator systems are roughly composed of an elevator car that moves up and down along a vertical shaft formed inside a building while carrying passengers inside, a mechanical unit that is equipped with a motor unit and a traction machine that generates a predetermined power to move the elevator car to a corresponding floor according to a button press by a passenger, and an elevator control unit that controls the mechanical unit according to a button press by a passenger so that the elevator car can operate smoothly and stably.

[0004] Conventional elevator systems close the elevator doors after a predetermined waiting time has elapsed after the doors have opened, or when the door close button has been pressed. This means that even if all passengers waiting to board have boarded the elevator, the elevator car will not depart until the door close waiting time has elapsed and the doors have closed. To shorten the door close waiting time, passengers are required to press the door close button.

[0005] However, additional manipulation of the door close button in this way may lead to the spread of viruses between passengers through contact with the button, and may also cause aging and damage to the button due to frequent manipulation of the door close button.

[0006] Meanwhile, in the elevator system, a display unit that displays the current floor and ascending direction of the elevator car can be placed on each platform, and such display unit can display not only the current floor and ascending direction of the elevator car, but also various status information of the elevator, such as fullness, inspection, breakdown, and moving.

[0007] However, since the display in the existing elevator system usually provides information on the status of the elevator through text, the user can only check the status of the elevator after approaching the platform. Furthermore, there is a limitation in that a user who does not see the display even after approaching the platform may end up waiting for a long time even though the elevator is under maintenance, broken, or otherwise unusable.

[0008] To overcome these limitations, an elevator system has recently been developed that provides voice guidance to users of elevators located further away when the elevator is unusable due to maintenance, breakdown, etc. However, since this voice guidance is continuously output until the unusable elevator condition, such as maintenance, breakdown, etc., is resolved, there is a problem of noise generation.

[0009] In addition, the conventional elevator system only transmits the status of the elevator by outputting status information of the inspection or malfunction even when the landing door that is not connected to the elevator car is open due to the elevator inspection or malfunction, which poses a problem in that safety accidents such as falls may occur to users who are not aware of this.

[0010] The present invention is intended to solve the problems of the prior art mentioned above, and the purpose of the present invention is to provide convenience in using an elevator by detecting all passengers boarding the elevator through an object detection sensor and automatically closing the elevator door.

[0011] In addition, another object of the present invention is to provide an elevator system that provides voice guidance on elevator status such as inspection, breakdown, abnormality, fullness, etc., but performs voice output only when an object determined to be a person scheduled to board the elevator is present on the platform.

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

[0013] At this time, the elevator system according to the present embodiment may further include a door control unit that controls the opening or closing of the elevator door based on the judgment of a passenger scheduled to board.

[0014] In addition, the door control unit can control the closing of the opened elevator door without a door closing input operation when it is determined that the passenger scheduled to board the elevator has completed boarding.

[0015] In addition, the door control unit can control the opening of the elevator door to close when the number of passengers scheduled to board, which was one or more while the door was open, becomes 0.

[0016] In addition, the passenger determination unit may include a dividing unit that divides the detection area into two or more zones, including a waiting zone around the platform door and a peripheral zone surrounding at least a portion of the waiting zone, an object tracking unit that tracks an object detected by the object detection sensor, a zone determination unit that determines a zone in which the tracked object is located, a speed determination unit that determines a moving speed of the tracked object, and a scheduled passenger determination unit that determines the tracked object as a scheduled passenger when the moving speed of the tracked object decreases by a predetermined amount or more after entering the waiting zone from the peripheral zone.

[0017] In addition, the passenger determination unit may further include a non-passenger determination unit that determines the tracked object as a non-passenger passing through the platform if the movement speed of the tracked object does not decrease by a predetermined amount or more after entering the waiting area from the surrounding area and the platform door is closed.

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

[0019] At this time, the passenger determination unit may further include a dividing unit that divides the detection area into three or more zones, including a waiting zone around the platform door, a perimeter zone surrounding at least a portion of the waiting zone, and a boarding / disembarking zone connecting the inside of the elevator car and the waiting zone, an object tracking unit that tracks an object detected by the object detection sensor, a zone determination unit that determines a zone in which the tracked object is located, a boarding passenger determination unit that determines a boarding passenger when the tracked object enters the disembarking zone from the waiting zone, an alighting passenger determination unit that determines a disembarking passenger when the tracked object enters the waiting zone from the alighting zone, and a remaining passenger determination unit that determines the remaining number of passengers based on the number of boarding passengers and the number of disembarking passengers.

[0020] In addition, the elevator may further include a status information generation unit that determines the status of the elevator and generates status information, a status information output unit that has a voice output unit to output the status information through voice guidance, and an output control unit that determines whether or not to output the voice guidance of the voice output unit based on the determination of a passenger scheduled to board.

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

[0022] Additionally, the above status information may include at least one of inspection, breakdown, moving, and full.

[0023] According to the present invention, after a person scheduled to board an elevator is detected, boarding of the elevator is completed and the door is controlled to close, and when a person scheduled to board is detected while the door is closing, the elevator door is opened to prevent a safety accident.

[0024] In addition, the present invention can improve user convenience by providing voice guidance on elevator status such as elevator inspection, breakdown, abnormality, full elevator, etc., and outputting voice only when an object determined to be a person planning to board the elevator is present on the platform.

[0037] In addition, it should be noted that the attached drawings are only intended to facilitate easy understanding of the spirit of the present invention, and should not be construed as limiting the spirit of the present invention by the attached drawings.

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

[0039] FIG. 1 is a functional block diagram of an elevator system according to one embodiment of the present invention, and FIG. 2 is a schematic drawing of a platform to which an elevator system according to one embodiment of the present invention is applied.

[0040] Hereinafter, an elevator system according to one embodiment of the present invention will be briefly described with reference to FIGS. 1 and 2.

[0041] An elevator system according to one embodiment of the present invention is characterized in that it provides voice guidance on elevator status such as inspection, breakdown, abnormality, full, etc., and performs voice output only when an object determined to be a person scheduled to board the elevator is present on the platform.

[0042] To this end, the elevator system according to the present embodiment may be configured to include a status information generation unit (100) that generates status information of the elevator, as illustrated in FIG. 1, a status information output unit (200) that outputs status information of the elevator, an object detection sensor (300) that detects an object on a platform, a passenger determination unit (400) that determines whether the object is a passenger, and an output control unit (500) that controls the output of the status information output unit (200).

[0043] The status information generation unit (100) can determine the status of the elevator and generate status information. Here, the status information generated by the status information generation unit (100) may include inspection, breakdown, moving, and full.

[0044] Specifically, the status information generation unit (100) can determine the status of the elevator as a maintenance state when the elevator operation mode is switched to a maintenance mode by the mode manipulation of the manager, and can determine the status of the elevator as a maintenance state when the elevator operation mode is switched to a moving mode by the mode manipulation of the manager. In addition, the status information generation unit (100) can determine the status of the elevator as a breakdown mode when a breakdown is detected in the elevator or the elevator operation mode is switched to a breakdown mode. In addition, the status information generation unit (100) can determine the status of the elevator as a full state when the weight of a passenger riding in the elevator car is measured to be more than a reference weight (e.g., 90% of the allowable boarding weight).

[0045] The status information output unit (200) outputs the status information generated by the status information generation unit (100) in various forms so that a person planning to board the elevator can check the status of the elevator.

[0046] Referring to FIG. 2, the status information output unit (200) may be equipped with a text output unit (210) that outputs status information through text guidance. The text output unit (210) is individually placed on each floor of the elevator, and can output not only status information but also information on the current location floor of the elevator car and information on the direction of entry and exit.

[0047] In addition, the status information output unit (200) may be equipped with a voice output unit (230) that outputs status information through voice guidance. The voice output unit (230) may also be individually placed on each floor of the elevator together with the text output unit (210). In this way, the elevator system according to the present embodiment can inform prospective passengers at a more distant location of the elevator's status by providing voice guidance on elevator statuses such as inspection, breakdown, abnormality, and fullness.

[0048] An object detection sensor (300) may be placed on a platform to detect an object in the detection area (a) of the platform. At this time, the object detection sensor (300) may be individually placed on each floor of the platform, and preferably, may be placed above the JAMB of the platform.

[0049] A radar sensor may be applied as the object detection sensor (300), but is not limited thereto, and various sensors that detect objects within a predetermined range may be applied as the object detection sensor (300). Preferably, a millimeter wave (mmWave) radar sensor may be applied as the object detection sensor (300) to improve object detection precision.

[0050] At this time, among the objects detected by the object detection sensor (300), there may be passengers scheduled to board the elevator, but there may also be non-passengers passing through the detection area of ​​the platform regardless of the elevator. When an object is detected by the object detection sensor (300), the passenger determination unit (400) can determine whether the object is a passenger scheduled to board or a non-passenger based on the detection information of the object detection sensor (300). Here, the passenger determination unit (400) is provided in the central control panel and can individually determine passengers scheduled to board each floor of the platform. A detailed description of the determination of passengers scheduled to board or non-passengers by the passenger determination unit (400) will be described later with reference to FIGS. 4 to 6. In addition, the passenger determination unit (400) can determine the number of remaining passengers inside the elevator car based on the detection information of the object detection sensor (300), and a detailed description thereof will be described later with reference to FIGS. 8 to 10.

[0051] The output control unit (500) can determine and control whether or not to output status information from the status information output unit (200). At this time, the output control unit (500) is provided in the central control panel and can individually control the status information output unit (200) of each floor of the platform.

[0052] Specifically, the output control unit (500) can control the text output unit (210) to constantly output the status information generated by the status information generation unit (100) when the status information generation unit (100) generates the status information. At this time, the status information output of the text output unit (210) can continue until the corresponding status is terminated. On the other hand, the voice output unit (210) may not constantly output the status information generated by the status information generation unit (100). Specifically, the output control unit (500) can determine whether to output the status information of the voice output unit (210) based on the judgment of the passenger determination unit (400) when the status information generation unit (100) generates the status information. Preferably, the output control unit (500) can control the voice output unit (230) to output the voice guidance only on the platform of the floor where the passenger determination unit (400) determines that there is at least one passenger scheduled to board.

[0053] In this way, the elevator system according to the present embodiment can prevent noise caused by meaningless voice guidance by performing voice output only when an object determined to be a person scheduled to board the elevator is present on the platform.

[0054] FIG. 3 is a flowchart illustrating a process of outputting elevator status information by voice in an elevator system according to one embodiment of the present invention.

[0055] Hereinafter, the status information voice output process of the elevator system according to the present embodiment will be described with reference to FIG. 3.

[0056] When the status information generation unit (100) generates status information such as inspection, breakdown, moving, full, etc. (S100), the output control unit (500) can control the character output unit (210) of each floor to output the status information in character form (S200).

[0057] And the output control unit (500) determines whether an object is detected by the object detection sensor (300) of each floor (S300), and if an object is detected (S300-Y), it can determine whether there is a floor that includes 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 that includes one or more passengers scheduled to board among the detected objects (S400-Y), the output control unit (500) can control the voice output unit (230) to output a guidance voice from the platform of the corresponding floor (S500).

[0059] On the other hand, if no object is detected (S300-N) or there is no passenger scheduled to board among the detected objects (S400-N), the guidance voice is not output from the platform of the corresponding floor, and object detection and determination of whether there is a passenger scheduled to board can be continued until the status of the generated elevator is terminated.

[0060] FIG. 4 is a functional block diagram illustrating a detailed configuration of a passenger determination unit according to one embodiment of the present invention, FIG. 5 is a diagram illustrating a detection area of ​​a platform in an elevator system according to one embodiment of the present invention, and FIG. 6 is a diagram illustrating an example of a passenger scheduled to board and a non-passenger in an elevator system according to one embodiment of the present invention.

[0061] Hereinafter, the passenger determination unit (400) of the configuration of the elevator system according to the present embodiment will be described in more detail with reference to FIGS. 4 to 6.

[0062] As described above, the passenger determination unit (400) can determine whether an object detected by the object detection sensor (300) is a passenger scheduled to board or a non-passenger. To this end, the passenger determination unit (400) may include, as illustrated in FIG. 4, a division unit (410) that divides a detection area, an object tracking unit (420) that tracks a detected object, a zone determination unit (430) that determines a zone where the tracked object is located, a speed determination unit (440) that determines a moving speed of the tracked object, a boarding passenger determination unit (450) that determines whether the tracked object is a passenger scheduled to board, and a non-passenger determination unit (460) that determines whether the tracked object is a non-passenger.

[0063] The partition (410) can partition the detection area to include a waiting area where passengers scheduled to board mainly wait, and a perimeter area arranged to surround at least a portion of the waiting area.

[0064] More specifically, referring to FIG. 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 perimeter of the waiting area (a1) excluding the elevator door (d) or the wall on the door (d) side into a perimeter area (a2). Preferably, the size of the waiting area (a1) can be set in proportion to the internal area of ​​the car, so that the size of the waiting area (a1) can be proportional to the number of people that the car can accommodate. Here, in FIG. 5, the detection area (a) and each zone partitioned have a square shape, but this is not limited thereto, and the detection area (a) and each zone partitioned can have a circular shape.

[0065] The object tracking unit (420) can distinguish and track the detected object based on the object detection information detected by the object detection sensor (300). That is, the object tracking unit (420) can identify the object detected by the object detection sensor (300) and track the movement path of the same object.

[0066] The zone determination unit (430) can determine the zone in which the tracked object tracked by the object tracking unit (420) is located based on the zone information of the zone unit. In addition, the speed determination unit (440) can determine the movement speed of the tracked object based on the movement path of the tracked object over time.

[0067] The passenger determination unit (450) that is scheduled to board receives the zone location of the tracked object from the zone determination unit (430) and determines the movement of the tracked object between zones, receives the movement speed of the tracked object over time from the speed determination unit (440) and determines the change in speed in each zone, and if the movement speed of the tracked object decreases by more than a standard after entering the waiting zone from the surrounding zone, the object can be determined to be a passenger that is scheduled to board.

[0068] As an example of FIG. 6, 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 perimeter area (a2), if the first object (u1) stops after entering the waiting area (a1) due to a decrease in movement speed exceeding a reference value, and the second object (u2) does not decrease in movement speed exceeding a reference value after entering the waiting area (a2), the passenger scheduled to board can be determined to be a passenger scheduled to board, but the second object (u2) can be determined to be not a passenger scheduled to board.

[0069] The non-passenger determination unit (460) receives the zone location of the tracked object from the zone determination unit (430) and determines the movement of the tracked object between zones, receives the movement speed of the tracked object over time from the speed determination unit (440) and determines the change in speed in each zone, and if the movement speed of the tracked object does not decrease by more than a standard after entering the waiting zone from the surrounding zone, the object can be determined to be a non-passenger.

[0070] As an example of FIG. 6, 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 perimeter area (a2), if the first object (u1) stops after entering the waiting area (a1) due to a decrease in movement speed exceeding a reference value, and the second object (u2) does not decrease in movement speed exceeding a reference value after entering the waiting area (a2), the non-passenger determination unit (460) may determine that the second object (u2) is a non-passenger, but the first object (u1) is not a non-passenger.

[0071] In addition, the non-passenger judgment unit (460) can judge an object as a non-passenger if the object that entered the perimeter area (a2) stops or moves out of the detection area without entering the waiting area (a1).

[0072] At this time, if the elevator door is open, passengers scheduled to board can board the elevator without slowing down in the waiting area (a1). Therefore, the determination of passengers scheduled to board by the passenger determination unit (450) based on the object's moving speed, or the determination of non-passengers by the non-passenger determination unit (460), can be performed under conditions where the elevator door is closed.

[0073] Preferably, the passenger determination unit (450) may determine that an object that entered the perimeter zone (a2) while the elevator door was open is a passenger that entered the waiting zone (a1) from the perimeter zone (a2), even if the object does not reduce its speed after entering the waiting zone (a1). Conversely, the non-passenger determination unit (460) may not determine that an object that entered the perimeter zone (a2) while the elevator door was open is a non-passenger, even if the object does not reduce its speed after entering the waiting zone (a1).

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

[0075] Hereinafter, with reference to FIGS. 7 to 10, a configuration for controlling a door based on the judgment of a passenger judgment unit (400) in an elevator system according to the present embodiment will be described.

[0076] The elevator system according to this embodiment is characterized in that it automatically closes the elevator door when all passengers scheduled to board the elevator have boarded after the door of the elevator has opened upon arrival at the platform, and it automatically closes the elevator door when all passengers inside the elevator car have disembarked after the door of the elevator has opened upon arrival at the platform, and there are no passengers remaining inside the car.

[0077] To this end, the elevator system according to the present embodiment includes a door control unit (600) that controls the opening or closing of an elevator door, and the door control unit (600) can control the closing of the elevator door based on detection information of an object detection sensor (300) or a judgment of a passenger judgment unit (400).

[0078] The door control unit (600) can control the closing of the elevator door if the object detection sensor (300) of the floor where the elevator has stopped does not detect an object in the detection area. Specifically, the door control unit (600) can wait for a set time from the time when the elevator door is fully opened when the elevator door is opened, and then control the closing of the elevator door if the object detection sensor (300) does not detect an object. In this case, the set time may be shorter than the time until the elevator door automatically closes, and may be sufficient time for the first passenger to disembark from inside the elevator. For example, the set time may be 3 seconds.

[0079] Preferably, the door control unit (600) can control the elevator door to close if, even if the object detection sensor (300) on the floor where the elevator has stopped detects an object, there is no object among the detected objects that is determined to be a passenger scheduled to board. Specifically, the door control unit (600) can control the elevator door to close if the number of passengers scheduled to board, which was one or more while the elevator door is open, becomes 0.

[0080] In this way, the elevator system according to the present embodiment determines when all passengers scheduled to board the elevator have boarded after the elevator door opens upon arrival at the platform and automatically closes the elevator door, thereby eliminating the need for passengers to separately press the close button, thereby preventing the spread of viruses through button contact. At this time, the elevator system according to the present embodiment may be applied with a voice recognition system that calls the elevator or inputs the destination floor using voice from the platform, and in this case, passengers do not need to touch the button throughout the entire process of using the elevator, thereby completely preventing the spread of viruses through button contact during elevator use.

[0081] Meanwhile, the door control unit (600) can control the closing of the elevator door based on the number of remaining passengers inside the elevator car. Specifically, the door control unit (600) can control the closing of the elevator door when the number of remaining passengers inside the elevator car is 0.

[0082] To this end, the passenger determination unit (400) may be provided with a boarding passenger determination unit (470) that determines boarding passengers boarding the elevator, as illustrated in FIG. 8, an alighting passenger determination unit (480) that determines alighting passengers getting off the elevator, and a remaining passenger determination unit (490) that determines remaining passengers inside the elevator car. At this time, the zone determination unit (430) of the passenger determination unit may divide the detection area (a) into a waiting area (a1), a perimeter area (b2), and an alighting area (a3). Here, the alighting area (a3) ​​may be an area connecting the waiting area (a1) and the inside of the elevator car (c), as in the examples illustrated in FIGS. 9 and 10.

[0083] As in the example illustrated in FIG. 9, the boarding passenger 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) while the elevator door is open. And, as in the example illustrated in FIG. 10, the disembarking passenger determination unit (480) can determine that an object (u4) tracked is a disembarking passenger if it enters the waiting area (a1) from the disembarking area (a3) ​​while the elevator door is open.

[0084] The remaining passenger determination unit (490) can determine the remaining passenger count inside the elevator car by comparing the number of passengers alighting and boarding determined at each floor's platform. Specifically, the remaining passenger determination unit (490) can determine the remaining passenger count as the number obtained by subtracting the total number of passengers alighting from the total number of passengers boarding on all floors.

[0085] In this way, the present invention can maximize elevator operation efficiency by automatically closing the elevator door when it is determined that all passengers inside the elevator car have disembarked and there are no passengers left inside the car after the door of the elevator that has arrived at the platform has opened.

[0086] Meanwhile, the door control unit (600) controls the opening or closing of the elevator door based on the platform call input, door close button input, door open button input, input destination floor, whether the elevator car has arrived at the platform, door opening time, etc. when the operation mode is the general mode, but controls the operation of the door according to the input operation of the administrator using a separate administrator operation module when the operation mode is switched to the inspection mode or the breakdown mode. For example, when the operation mode is the general mode, the door control unit (600) automatically closes an opened elevator door when a set time has elapsed, but when the operation mode is the inspection mode, if no closing input operation through the administrator operation module occurs even after the set time has elapsed, the opened elevator door may not be closed.

[0087] At this time, in this embodiment, the door control unit (600) can control the closing of the open elevator door of the corresponding platform immediately upon detection of a passenger scheduled to board, even if the operation mode is a maintenance or failure mode and no closing input operation is performed through the manager operation module. Here, the elevator door includes a platform door and a car door, and if an elevator car is not located in the corresponding platform, the door control unit (600) can control the closing of the platform door of the corresponding platform separately from the car door.

[0088] Accordingly, the present invention can prevent safety accidents such as falling from occurring to users who are unaware of the fact that a landing door not connected to an elevator car is open due to elevator maintenance or malfunction.

[0089] The above description is merely an illustrative illustration of the technical idea of ​​the present invention, and those skilled in the art will appreciate that various modifications and variations can be made without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the technical idea of ​​the present invention, and the scope of the technical idea of ​​the present invention is not limited by these embodiments.
