Description

  The present invention relates to an elevator system that is provided in a building on a plurality of floors and that moves an elevator up and down.

  Conventionally, an elevator is used as a moving means for each floor in a multi-storey building. Elevators are required to have high convenience, and various proposals have been made to meet the demands.

  For example, an elevator call prohibiting function is known in which button operation in an elevator hall on a predetermined floor is prohibited only during a specific time period, and passengers can get on and off at other floors.

  Regarding an elevator system having such an elevator call prohibition function, Patent Document 1 discloses an elevator system that accepts cancellation of the elevator call prohibition function by an administrator by projecting an image near the elevator on a television monitor in the management room. ing. According to this elevator system, a passenger sensor is provided in the vicinity of the elevator, and when the passenger sensor detects a passenger who has arrived in the vicinity of the elevator during a period when the elevator call is prohibited, the television camera automatically operates and the image is displayed. Is displayed on the TV monitor in the management room. And the manager judges the contents of the television monitor, and if it is a passenger, lifts the elevator call prohibition.

Japanese Unexamined Patent Publication No. Hei 6-278756

  The facility staff engaged in the work at the power plant facility will change to work clothes in the changing room after moving to the office, and then move to their work place. Here, when the work place is on the upper floor of a multi-storey building, the facility staff moves to the upper floor using an elevator.

  For example, if the changing room is on the first floor and the workplace is on the third floor, the facility staff moves from the changing room to the first-floor elevator hall after changing clothes, calls the elevator by operating the buttons, and enters the elevator. Get on the 3rd floor.

  In this case, the elevator arriving on the third floor waits on the third floor as long as no button operation is performed in the elevator hall on the other floor. For this reason, when the facility staff moves from the changing room to the first floor elevator hall, there is a high possibility that the elevator is stopped on the third floor. As a result, after pressing the use button on the first floor, the facility staff waits for a while until the elevator gets down to the first floor, then gets into the elevator and moves to the upper floor.

  However, during work hours, the facility staff moves into the changing room one after another, changes to work clothes, and then moves from the first floor to the third floor by an elevator. At this time, the elevator stopped on the 3rd floor is lowered to the 1st floor by the next facility member operating the button in the 1st floor elevator hall. I will wait for arrival.

  By the way, it is most preferable for the facility staff who changed into work clothes to have the elevator waiting on the first floor when moving to the elevator hall on the first floor. Therefore, it is conceivable to place a manager who manages the changing room and the elevator and remotely operate the elevator. However, it is likely that the cost of the manager will be increased because it takes much labor costs.

  An object of the present invention is to provide an elevator system that solves such problems and realizes improvement of convenience of the elevator without manpower.

  In order to achieve the above object, the present invention has the following configuration.

  (1) An elevator installed in a building on multiple floors, where people and goods are moved on and off each floor to move each floor, and provided in an elevator hall on each floor. A call device that generates an instruction input to move to a hall, and a drive that monitors the presence or absence of an instruction input from the call device on each floor and performs control to move the elevator to the floor corresponding to the call device that has received the instruction input In an elevator system comprising a control device, a detection means for detecting a person in the room in a room near an elevator hall on a predetermined floor, and determining whether there is a person in the room from the output of the detection means. When the room determination means and the room presence determination means determine that there is a person in the room, the call device is automatically controlled to generate an instruction input. Elevator system is characterized in that a cell call control means.

  According to (1), when a person (for example, a power plant facility worker) is present in a room (for example, a changing room) near the elevator hall, the call panel is automatically controlled to The same instruction input as that generated when operated is generated, and the elevator is automatically moved to the floor of the room. As a result, the person who leaves the room does not have to wait for the elevator so much, and can get into the elevator early and move to the target floor. Thus, the convenience of the elevator can be improved without manpower.

  (2) In (1), there is provided time zone determination means for determining whether or not the current time is in a preset time zone, and the occupancy determination means has the above-mentioned presence status in the first time zone. An elevator system characterized by determining whether or not there is a person in the room when the time zone determination means determines.

  According to (2), for example, a time zone in which a room is frequently used (for example, a work time zone) is set as a first time zone, and in this first time zone, a person (for example, a changing room) When a power plant facility staff member is present in the room, the call device is automatically controlled to generate an instruction input, and the elevator is automatically moved to the floor of the room. Thereby, the convenience of the elevator can be improved.

  (3) In (2), the detection means is provided at the entrance of the room, and is provided at a first sensor that detects that a person has passed through the entrance, and at the exit of the room. A second sensor that detects that a person has passed, and the first sensor starts measuring time when a person has passed through the entrance, and the second sensor has detected that a person has passed through the exit. Timer means for stopping timing, and the call control means determines that the current time is in a second time zone different from the first time zone, the time zone determining means determines, and the timer means An elevator system that automatically controls the calling device to generate an instruction input when a measured value is within a predetermined time.

  According to (3), it is estimated that a person who enters a room (for example, a changing room) from the entrance and exits from the exit within a predetermined time (for example, a power plant facility staff) is likely to use the elevator. The call device is automatically controlled to generate an instruction input. As a result, the elevator can be automatically moved to the floor of the room, and the convenience of the elevator can be improved.

  (4) In (1), the detection means includes a video acquisition unit that acquires the video of the room, analyzes the video acquired by the video acquisition unit, and colors the clothes of the person in the room Video analysis means for obtaining information, wherein the occupancy determination means determines whether or not the color information obtained by the video analysis means is predetermined color information, and the call control means includes the occupancy determination means However, when it is determined that the color is a specific color, the call device is controlled to generate an instruction input.

  According to (4), for example, when the room is a changing room for changing into work clothes, the person wearing the work clothes is likely to use the elevator, and the person not wearing the work clothes is the elevator. It can be estimated that the possibility of using is low. Therefore, the video analysis means identifies the color of the work clothes, and when the color identified by the video analysis means is the same as the color of the work clothes, the call device is automatically controlled to generate an instruction input. Thereby, the convenience of the elevator can be improved by automatically moving the elevator to the floor of the room.

  (5) In (4), there is provided time zone determination means for determining whether or not the current time is in a preset time zone, and the call control means is configured to determine the time when the current time is in the first time zone. When the band determining means determines and the occupancy determining means determines that there is a person in the room, the calling device is automatically controlled to output an instruction input, and the time zone determining means Is determined to be in a second time zone different from the first time zone, and when the occupancy determination means determines that the color of the clothes of the person in the room is a specific color, the calling device An elevator system characterized in that it automatically controls to generate an instruction input.

  According to (5), for example, in the first time zone where there are many people going into and out of the room (for example, changing rooms) as in the work hours, there are many people using the elevator in the room. If there are people in the room, move the elevator to the floor of the room. Also, for example, in the first time zone where there are few people entering and leaving the room, such as business hours, if the person is wearing work clothes, the call device is automatically controlled to generate an instruction input, and the elevator Move to the floor of the room. In this way, it is possible to move the elevator to the floor of the room as needed according to the usage situation of the room, and it is possible to improve the convenience of the elevator.

  According to the present invention, it is possible to improve the convenience of an elevator without manpower.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[First Embodiment]
FIG. 1 is an explanatory diagram showing an overview of an elevator system according to a first embodiment of the present invention. The elevator system 1 includes a human sensor 10, a calling device 12, and an elevator 50 corresponding to detection means.

  The elevator 50 is provided in a building on a plurality of floors in a power plant facility, and moves on each floor by getting on and off facility members and supplies of the power plant facility. In the present embodiment, an example will be described in which the elevator 50 is installed in a five-story building in which the lowest floor is the first floor and the uppermost floor is the fifth floor.

  The human sensor 10 is provided in the changing room 100 and detects a person in the changing room 100. As the human sensor 10, for example, a PIR (Passive Infra Red) sensor that detects a change in ambient temperature and outputs a detection signal is applicable.

  The calling device 12 is for calling the elevator 50 and is provided on each floor of the building. In this embodiment, both the operation panel 30 and the controller 20 are provided only in the calling device 12 provided in the elevator hall 40 on the first floor, and only the operation panel 30 is provided on the other floors. .

  The operation panel 30 includes an elevating button 32 that can be operated by a user such as a facility worker or a facility visitor. When the facility staff presses the lift button 32, an instruction input is generated and transmitted to the drive control device 55 of the elevator 50. When receiving the instruction input, the drive control device 55 operates a drive device (not shown) of the elevator 50 to move the elevator 50 to the floor where the instruction input is transmitted. In this way, the elevator 50 can be called in the elevator hall 40 on the floor where the instruction input from the operation panel 30 by the facility staff is performed. Moreover, the raising / lowering button 32 is provided with an electrical light emitting member (for example, a miniature bulb) inside, and when the raising / lowering button 32 is pressed, the light emitting member is turned on. For this reason, it becomes possible to identify whether the elevating button 32 is pressed or not according to the lighting state of the light emitting member. The lift button 32 includes an ascending button and a descending button. The operation panel 30 on the first floor is provided with only the ascending button, and the operation panel 30 on the fifth floor is provided with only the descending button. The operation panels 30 from the second floor to the fourth floor are provided with an up button and a down button. The light emitting member provided in the lift button 32 emits light when the lift button 32 is pressed, and then turns off when the elevator 50 arrives at the elevator hall 40.

  The controller 20 is for automatically calling the elevator 50 regardless of the operation of the operation panel 30 by the facility staff. Although details will be described later, the controller 20 automatically controls the calling device 12 to transmit an instruction input to the drive control device 55 when the human sensor 10 detects that there is a person in the changing room 100. At this time, the drive control device 55 has the same instruction input transmitted from the call device 12 by the facility staff operating the operation panel 30 and the instruction input transmitted from the call device 12 under the control of the controller 20. Recognize as a signal.

  FIG. 2 is a block diagram showing a control system of the elevator system according to the first embodiment of the present invention. The elevator 50 is controlled by the drive control device 55 to perform operations such as raising / lowering, stopping, and opening / closing the door. A call device 12 provided on each floor is connected to the drive control device 55. In the calling device 12 on each floor, the 1F calling device 12 is called the 1F calling device 12a, the 2F calling device 12 is the 2F calling device 12b, the 3F calling device 12 is the 3F calling device 12c, and the 4F calling device 12 is called the 4F. The calling device 12 of the devices 12d and 5F is referred to as a 5F calling device 12e.

  The 1F calling device 12 a includes a lift button 32 and a controller 20. The controller 20 includes a CPU 22, a RAM 24, an interface 26 and a clock 28. A RAM 24, an interface 26, and a clock 28 are connected to the CPU 22. The human sensor 10 is connected to the interface 26.

  The CPU 22 controls the entire controller 20 and functions as occupancy determination means, call control means, and time zone control means.

  The occupancy determination means (CPU 22) determines whether there is a person in the changing room 100 based on the detection signal output from the human sensor 10. Specifically, when the detection signal output from the human sensor 10 is received, it is determined that there is a person in the changing room 100, and when no detection signal is received from the human sensor 10, It is determined that there is not.

  The call control means (CPU 22) causes the drive control device 55 to transmit the same instruction input as when the lift button 32 is pressed when the occupancy determination means (CPU 22) determines that there is a person in the changing room 100 It is.

  Specifically, the calling device 12a is provided with two contact points that are brought into a conducting state when the elevating button 32 is pressed, and are brought into a non-conducting state when the raising button 32 is released. Then, an on / off signal generated by pressing and releasing the up / down button 32 is transmitted to the drive control device 55 as an instruction input. Further, a switching element is connected between the two contacts, and the switching element is turned on and off by applying a voltage to the switching element under the control of the call control means (CPU 22). As a result, the same instruction input as when the lift button 32 is pressed is transmitted to the drive control device 55.

  The time zone control means (CPU 22) executes the functions of the occupancy determination means (CPU 22) and the call control means (CPU 22) in a preset time zone.

  In addition, the RAM 24 stores a time zone in which the human sensor 10 is activated to enter a sensing state for sensing people. Specifically, in the morning working hours, for example, when 9 am is the starting time, the time from 8 am to 9:30 am is stored.

  The interface 26 connects the controller 20 and an external device so as to be able to transmit and receive. The human sensor 10 and the controller 20 are wired or wirelessly connected via an interface 26.

  The clock 28 measures the current time. The time zone control means (CPU 22) executes the functions of the occupancy determination means and the call control means when the current time counted by the clock 28 is within the range of the attendance hours stored in the RAM 24. When it is out of the working hours, the functions of the occupancy determination means and the call control means are stopped. That is, in the time zone other than the attendance time zone stored in the RAM 24, the elevator 50 is called by pressing the up / down button 32 as usual.

  Further, the time zone control means (CPU 22) causes the human sensor 10 to start the detection mode when the current time counted by the clock 28 reaches the start time of the work time zone stored in the RAM 24. Controls transmission of signals. When the human sensor 10 receives a signal for starting the detection mode from the time zone control means (CPU 22), the human sensor 10 switches the state of the human sensor 10 to a detection mode for detecting a person in the changing room 100. Further, the time zone control means (CPU 22) causes the human sensor 10 to start the sleep mode when the current time counted by the clock 28 reaches the end time of the work time zone stored in the RAM 24. Controls transmission of signals. When the human sensor 10 receives a signal for starting the sleep mode from the time zone control means (CPU 22), the human sensor 10 changes the state of the human sensor 10 from the detection mode to the sleep mode in which the human sensing in the changing room 100 is stopped. Switch to. The human sensor 10 does not detect a person in the changing room 100 in the pause mode.

  FIG. 3 is a flowchart showing an operation switching process executed in the controller. The CPU 22 of the controller 20 executes the operation switching process shown in FIG. 3 every predetermined time (for example, every 5 seconds).

  First, in step S10, the CPU 22 determines whether or not the time value of the clock 28, that is, the current time is within the range of the attendance hours stored in the RAM 24, and determines that it is within the range. Moves the process to step S12. If not determined to be within the range, the process proceeds to step S22.

  In step S12, the CPU 22 determines whether or not the human sensor 10 is in the pause mode. If it is determined that the human sensor 10 is in the pause mode, the process proceeds to step S14. If it is not determined that the sleep mode is set, the process proceeds to step S16.

  In step S <b> 14, the CPU 22 performs processing for transmitting a signal for starting the detection mode to the human sensor 10. If this process ends, the process moves to a step S16.

  In step S <b> 16, the CPU 22 performs a process of determining whether there is a person in the changing room 100 based on the detection result of the human sensor 10. Specifically, when the CPU 22 receives a detection signal from the human sensor 10, the CPU 22 determines that there is a person in the changing room 100, and when no detection signal is received from the human sensor 10, a person enters the changing room 100. Not determined. If it is determined that there is a person in the changing room 100, the process proceeds to step S18. If it is not determined that there is a person in the changing room 100, the operation switching process is terminated.

  In step S18, the CPU 22 performs a process of determining whether or not the elevator 50 is stopped on the first floor. When it is determined that the elevator 50 is stopped on the first floor, the operation switching process is terminated. If it is not determined that the elevator 50 is stopped on the first floor, the process proceeds to step S20.

  In step S <b> 20, the CPU 22 performs a process of generating an instruction input in the calling device 12 and transmitting it to the drive control device 55. Moreover, CPU22 performs the process which light-emits the light emitting member (for example, miniature light bulb) provided in the raising / lowering button 32. FIG. When this process ends, the operation switching process ends.

  In step S <b> 22, the CPU 22 performs processing for transmitting a signal for starting the sleep mode to the human sensor 10. The human sensor 10 switches from the detection mode to the pause mode by receiving a signal for starting the pause mode, and pauses the detection of the person in the changing room 100. When this process ends, the operation switching process ends.

  Thus, according to the present embodiment, for example, when 8 am to 9:30 am is stored as the attendance time zone stored in the RAM 24, 8 am to 9 am When the facility staff enters the changing room 100 within 30 minutes, it is automatically the same as when the lift button 32 of the 1F calling device 12a is pressed, and the elevator 50 enters the elevator hall 40 on the first floor. Moving. And the elevator 50 is designated when the facility member who got into the elevator 50 from the elevator hall 40 on the first floor operates the operation panel (not shown) provided in the elevator 50 and designates the moving floor. Move to a moving floor (for example, 3F). After the elevator 50 moves to the third floor, when the operation panel 30 is not operated on any floor other than the third floor and there is a person in the changing room 100, an instruction input is generated from the first floor calling device 12a. Therefore, the elevator 50 on the third floor moves to the first floor.

  Further, when the elevator 50 arrives at the first floor and is in a stopped state, the controller 20 does not generate an instruction input even if it receives a detection signal from the human sensor 10. For this reason, for example, when the elevator button 32 is pressed while the door of the elevator 50 transitions from the open state to the closed state, the door of the elevator 50 is opened again, but the door of the elevator 50 changes from the open state to the closed state. Even if the controller 20 receives a detection signal from the human sensor 10 during the transition, the door of the elevator 50 is closed.

  FIG. 4 is a floor view showing an example of arrangement of the changing room 100 and the elevator hall on the first floor of the building. On the first floor of the building, an elevator 50 is installed in the center, and an elevator hall 40 is provided on the side of the elevator 50. In addition, a changing room 100 is provided in an area that allows direct access from outside. The changing room 100 has a first doorway 102 that allows entry into and out of the changing room 100 from the outside, and access to the indoor passage 106 from the changing room 100 or into the changing room 100 from the indoor passage 106. A possible second doorway 104 is provided. The indoor passage 106 extends toward the elevator hall 40, and the facility staff can move to the elevator hall 40 through the indoor passage 106. Further, a third doorway 108 is provided on the side of the changing room 100 so as to allow entry into and out of the building from the outside.

  The facility staff is obliged to change into work clothes in the changing room 100 before starting a predetermined operation. For this reason, in the morning work hours, many facility staff enter the changing room 100 from the first doorway 102 and change into work clothes. After changing to work clothes, the facility staff uses the elevator 50 or moves to the workplace through the stairs 110 when working on the floor of the building. A facility worker who works outdoors moves from the first doorway 102 to the outdoors. Alternatively, the vehicle moves from the second doorway 104 through the indoor passage 106 to the outside through the third doorway 108.

  As described above, according to the first embodiment, when a facility member enters the changing room 100 between 8 am and 9:30 am, an instruction input is generated from the 1F calling device 12a, The elevator 50 on the upper floor moves to the first floor. In this case, a facility member enters the changing room 100 from the first doorway 102 and exits from the first doorway 102, or a facility member who goes down to the first floor by the elevator 50 passes through the indoor passage 106 and enters the changing room from the second doorway 104. Even when the elevator 50 is not used, such as when entering the room 100, the elevator 50 moves to the first floor. However, in the first embodiment, many facility personnel change into work clothes using the changing room 100 and move to the floor of the building using the elevator 50. Therefore, the facility members who do not use the elevator 50 are used. Even if the elevator 50 moves to the first floor by detecting the human sensor 10, it is highly possible that a facility member who uses the elevator 50 is present in the changing room 100. For this reason, there is almost no result of moving the elevator 50 wastefully.

[Second Embodiment]
In the second embodiment described below, a facility member who has entered the changing room 100 is likely to move to the elevator hall 40 in a time zone other than the work hours (8 am to 9:30 am). When the controller 20 determines that the person is a facility member, the elevator 50 is moved to the first floor.

  FIG. 5 is a block diagram showing a control system of the elevator system according to the second embodiment of the present invention. FIG. 6 is an explanatory diagram showing an overview of an elevator system according to the second embodiment of the present invention. In addition, about the member same as the member in 1st Embodiment shown in FIG. 1, FIG. 2, or the member of the same function, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted. In the elevator system 1 of the second embodiment, a first passing sensor 60 and a second passing sensor 62 are further installed in the changing room 100 with respect to the elevator system 1 in the first embodiment.

  The first passage sensor 60 is provided near the first doorway 102 in the changing room 100 and detects a person who has passed through the first doorway 102. The second passage sensor 62 is provided near the second doorway 104 in the changing room 100 and detects a person who has passed through the second doorway 104. The first passage sensor 60 and the second passage sensor 62 may be PIR sensors like the human sensor 10, but the first passage sensor 60 and the second passage sensor 62 detect the passage of the facility staff. As long as it is possible, it is not necessary to use a PIR sensor for detecting a wide area like the human sensor 10. Also. The first passage sensor 60 and the second passage sensor 62 may not be PIR sensors.

  The predetermined storage area of the RAM 24 of the second embodiment includes a timer area that functions as a timer by storing and updating a value that the CPU 22 adds 1 every fixed time. The function of the RAM 24 as a timer corresponds to the timer means. The RAM 24 stores a work time zone in addition to the attendance time zone. As the business hours, for example, 9:30 am to 4 pm are set. Here, the attendance time zone corresponds to the first time zone, and the business time zone corresponds to the second time zone.

  FIG. 7 is a flowchart showing an operation switching process executed in the controller according to the second embodiment. The CPU 22 of the controller 20 executes an operation switching process shown in FIG. 7 every predetermined time (for example, every 5 seconds).

  Since the process of step S10-step S22 after starting the driving | operation switching process shown in FIG. 7 is the same as the flowchart of 1st Embodiment shown in FIG. 3, description is abbreviate | omitted. When the process of step S22 is completed, the process of step S24 is moved.

  In step S24, the CPU 22 executes a business time period operation switching process. The business time zone operation switching process will be described later with reference to FIG. When this process ends, the operation switching process ends.

  FIG. 8 is a flowchart showing a subroutine executed in the operation switching process shown in FIG. In step S24 shown in FIG. 7, the operation time zone operation switching process shown in FIG. 7 is executed.

  First, in step S30, the CPU 22 determines whether or not the time value of the clock 28, that is, the current time is within the business time zone stored in the RAM 24, and determines that it is within the range. Moves the process to step S32. If not determined to be within the range, the process proceeds to step S52.

  In step S32, the CPU 22 determines whether or not the first passage sensor 60 and the second passage sensor 62 are in the pause mode. Here, the pause mode is a mode in which no detection signal is output from the first passage sensor 60 and the second passage sensor 62 even if the facility member passes through the first passage sensor 60 and the second passage sensor 62. If it is determined that the sleep mode is set, the process proceeds to step S34. If it is not determined that the sleep mode is set, the process proceeds to step S36.

  In step S34, the CPU 22 performs processing for setting the first passage sensor 60 and the second passage sensor 62 to the detection mode. Here, the detection mode is a mode in which a detection signal is output from the first passage sensor 60 and the second passage sensor 62 when the facility member passes through the first passage sensor 60 and the second passage sensor 62. If this process ends, the process moves to a step S36.

  In step S <b> 36, the CPU 22 performs a process of determining whether a person has passed through the first doorway 102 based on the detection result of the first passage sensor 60. If it is determined that a person has passed through the first doorway 102, the process proceeds to step S38. If it is not determined that a person has passed through the first doorway 102, the process proceeds to step S40.

  In step S38, the CPU 22 performs processing for starting a timer. Specifically, the count value stored in the timer area of the RAM 24 is updated to a value obtained by adding 1 at regular intervals. If this process ends, the process moves to a step S40.

  In step S <b> 40, the CPU 22 performs a process of determining whether a person has passed through the second doorway 104 based on the detection result of the second passage sensor 62. If it is determined that a person has passed through the second doorway 104, the process proceeds to step S42. If it is not determined that a person has passed through the second door 104, this subroutine is terminated.

  In step S42, the CPU 22 performs a process for stopping the timer. Specifically, processing for stopping the update of the count value stored in the timer area of the RAM 24 is performed. If this process ends, the process moves to a step S44.

  In step S44, the CPU 22 performs processing for comparing the timer value with the set value. The set value is a value stored in advance in a predetermined area of the RAM 24, and after the facility person enters the changing room 100 from the first doorway 102, he changes to work clothes and exits the changing room 100 from the second doorway 104. Is remembered. If the CPU 22 compares the timer value with the set value and determines that the timer value is greater than the set value, the process proceeds to step S46. If the timer value is compared with the set value and it is not determined that the timer value is greater than the set value, the process proceeds to step S50.

  In step S46, the CPU 22 performs a process of determining whether or not the elevator 50 is stopped on the first floor. If it is determined that the elevator 50 is stopped on the first floor, the process proceeds to step S50. If it is not determined that the elevator 50 is stopped on the first floor, the process proceeds to step S48.

  In step S <b> 48, the CPU 22 performs a process of generating an instruction input in the calling device 12 and transmitting it to the drive control device 55. Moreover, CPU22 performs the process which light-emits the light emitting member (for example, miniature light bulb) provided in the raising / lowering button 32. FIG. If this process ends, the process moves to a step S50.

  In step S50, the CPU 22 performs a process of clearing (counting 0) the count value stored in the timer area of the RAM 24. When this process is finished, this subroutine is finished.

  In step S <b> 52, the CPU 22 performs a process for setting the first passage sensor 60 and the second passage sensor 62 to the pause mode. When this process is finished, this subroutine is finished.

  As described above, according to the second embodiment, the second passage is performed after the first passage sensor 60 detects the facility member in a time zone in which the changing room 100 is less used, for example, in a business time zone after the work hours. The time until the sensor 62 detects a facility member is measured. If this measurement time is longer than the set time, it is estimated that there is a high possibility that the facility staff will move to the elevator hall 40 through the changing room 100, and the elevator 50 is moved to the first floor. As a result, even during business hours, when the facility staff moves to the elevator 50, the elevator 50 can be brought to the first floor or moved to the first floor. Improved convenience.
