[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the embodiments described below, the configuration of an elevator monitoring system having an elevator of the present invention will be described first, and then the elevator and elevator monitoring method implemented by the elevator monitoring system will be described.

[0010] <Elevator monitoring system> Fig. 1 is a schematic configuration diagram of an elevator monitoring system 1 according to an embodiment. Fig. 2 is a block diagram of the elevator monitoring system 1 according to an embodiment. The elevator monitoring system 1 shown in Figs. 1 and 2 includes an elevator 100, a remote control center monitor 200 as a management monitor, and a control center monitor 300. These are as follows.

[0011] <Elevator 100> The elevator 100 has a car 10. The car 10 is equipped with car doors 12 for passengers to enter the car, and travels within a track 100a that extends along the building. Landing doors 21 are provided on the wall of the track 100a. The landing doors 21 are provided facing each landing 100f, and engage with the car doors 12 when the car 10 arrives at each landing 100f, and open and close in response to the opening and closing drive of the car doors 12.

[0012] An in-car operation panel 13 is provided inside the car 10. The elevator 100 also has an above-car camera 14 provided on the top of the car 10, an below-car camera 15 provided on the bottom of the car 10, and a pit camera 16 provided in a pit 100b below the runway 100a. The elevator 100 also has an elevator control device 17, a video control device 18, and a remote monitoring device 19. The elevator 100 also has a hall operation panel 22 near each hall door 21. The main components of the elevator 100 will be described below in order.

[0013] [In-car operation panel 13] 3 is a plan view of an elevator car operation panel 13 according to the embodiment. The car operation panel 13 includes an in-car monitor 13a, an in-car camera 13b, and an in-car call registration unit 13c, as well as an operation mode switching switch and a communication device that enables communication with the outside world, both of which are not shown here.

[0014] The car interior monitor 13a displays images transmitted from the image control device 18, which will be described later. Figure 4 is a diagram illustrating the display on the car interior monitor 13a. The images displayed on the car interior monitor 13a are the current floor of the car 10, the direction of movement of the car 10, and an image of one of the multiple landings 100f (see Figure 1). The image of the landing 100f is an image of the landing captured by a landing camera, which will be described later. This allows the passenger [p1] in the car 10 to observe the state of one of the multiple landings 100f from the landing image displayed on the car interior monitor 13a.

[0015] 3 and 4, the car interior camera 13b captures images of the inside of the car 10 and transmits the captured images of the inside of the car to the image control device 18 (see FIGS. 1 and 2). The car interior call registration unit 13c has a call registration button that allows a passenger [p1] in the car 10 to register a destination floor, and also has, nearby, an open / close button for opening or closing the car door 12 (see FIG. 1), and a call button that enables communication with the management center, which will be described later.

[0016] An operation switch (not shown) is used to switch the elevator operation mode controlled by the elevator control device 17 (described below) from normal operation mode to maintenance mode. This operation switch can only be operated by a worker during maintenance work. Switching the operation switch also enables the display on the car monitor 13a to be switched.

[0017] The in-car monitor 13a and the in-car camera 13b are not limited to being provided on the in-car operation panel 13, and may each be provided in a separate location independent of the in-car call registration unit 13c. The in-car monitor 13a may be installed, for example, in a position that is easily visible to the passenger [p1] inside the car 10. The in-car camera 13b may be installed in a location where it can capture images of the passenger [p1] inside the car 10 or where it can capture images of the inside of the car that make it easy to understand the situation inside the car 10.

[0018] [Cab-top camera 14, cab-bottom camera 15, and pit camera 16] 1 and 2, the car-top camera 14, the car-bottom camera 15, and the pit camera 16 are maintenance cameras installed outside the car 10. These maintenance cameras are used to check the conditions above and below the car 10, as well as inside the pit 100b, during maintenance work. These maintenance cameras transmit the captured images to the image control device 18.

[0019] [Elevator Control Device 17] Elevator control device 17 controls the running of car 10 and the opening and closing of car door 12 based on signals from in-car operation panel 13 and hall operation panel 22, as well as signals from a remote control center and a control center, which will be described later. Elevator control device 17 may be located, for example, in pit 100b below runway 100a, or it may be located in a machine room (not shown) within runway 100a or above runway 100a.

[0020] Such an elevator control device 17 is configured by a computer. The computer is hardware used as a so-called computer, and includes a CPU (Central Processing Unit), non-volatile storage units such as RAM (Random Access Memory) and ROM (Read Only Memory), and also a network interface.

[0021] [Platform operation panel 22] 5 is a plan view of the hall operation panel 22 of the elevator according to the embodiment. The hall operation panel 22 includes a hall monitor 22a, a hall camera 22b, and a hall call registration unit 22c.

[0022] The hall monitor 22a displays images transmitted from the image control device 18, which will be described later. Fig. 6 is a diagram illustrating the display on the hall monitor 22a. One of the images displayed by the hall monitor 22a is an image of the interior of the car 10 captured by the car interior camera 13b (see Figs. 2 to 4). This allows passengers (hereinafter referred to as users [p]) waiting to board the car 10 at each hall 100f to observe the state of the interior of the car 10 that they are about to board, from the image of the interior of the car displayed on the hall monitor 22a.

[0023] In addition, the hall monitor 22a may also display the current floor of the car 10 and the direction of movement of the car 10. Furthermore, the hall monitor 22a may have an alert function that notifies the occurrence of an abnormal situation by flashing or the like when the elevator control device 17 detects an operation of an emergency call button in the car (not shown), or when it detects a disturbance or other abnormality in the car 10. Furthermore, the hall monitor 22a may have a recording function to enhance the crime prevention effect.

[0024] 5 and 6, the hall camera 22b photographs the hall 100f and transmits the photographed hall image to the image control device 18 (see FIGS. 1 and 2). The hall call registration unit 22c has a button that allows a user [p] waiting to board the car 10 at the hall 100f to call the car 10.

[0025] The hall monitor 22a and the hall camera 22b are not limited to being provided on the hall operation panel 22, and may be provided in separate locations independent of the hall call registration unit 22c. The hall monitor 22a may be provided in a large area on the surface of the hall door 21 (see FIG. 1) at each hall 100f, instead of vision glass, or may be installed in a large area on the wall beside the hall door 21. The hall camera 22b may be installed in a location where it can capture images of users [p] waiting at the hall 100f or a location where it can capture images of the hall that make it easy to grasp the situation at the hall 100f.

[0026] [Video Control Device 18] 1 and 2, video control device 18 aggregates images captured by in-car camera 13b, hall camera 22b, and maintenance cameras such as car-mounted camera 14, car-mounted camera 15, and pit camera 16. Based on information from elevator control device 17, video control device 18 controls the display of images on in-car monitor 13a, hall monitor 22a, and further on remote control center monitor 200 and control center monitor 300. Video control device 18 is configured by a computer and may be incorporated into elevator control device 17.

[0027] The video control device 18 is connected to the in-car monitor 13a, in-car camera 13b, above-car camera 14, and below-car camera 15 provided in the elevator car 10 by a moving cable 18a for transmitting and receiving video signals. The moving cable 18a may be built into the moving cable used for elevator control, or may be laid separately. The video control device 18 is also connected to the hall monitor 22a and hall camera 22b of each hall operation panel 22, as well as to the pit camera 16, and is further connected to the control center monitor 300 and the remote monitoring device 19 by video wiring (not shown).

[0028] [Remote Monitoring Device 19] The remote monitoring device 19 is a device for transmitting and receiving video images to and from the remote management center monitor 200 using a telephone line. The transmission of video images from the remote monitoring device 19 to the remote management center monitor 200 is carried out based on instructions from the video control device 18.

[0029] <Remote Control Center Monitor 200> The remote control center monitor 200 is an external management monitor installed at a location away from the local building where the elevator 100 is installed. The remote control center monitor 200 is installed in a remote control center used by, for example, the building manager of the local building or an elevator maintenance technician. This remote control center monitor 200 is connected to the video control device 18 via the remote monitoring device 19, and displays the video transmitted from the video control device 18.

[0030] <Management Center Monitor 300> The control center monitor 300 is an external control monitor that can be directly connected to the video control device 18 via video wiring (not shown). The control center monitor 300 is placed in a control center (for example, a control room or a disaster prevention center) in the local building.

[0031] <Elevator monitoring method> Next, the elevator monitoring method implemented by the above-described elevator monitoring system 1 will be described in the order of the display procedure of the car monitor, the display procedure of the hall monitor, and the display procedure during maintenance.

[0032] <In-car monitor display procedure> Fig. 7 is a flowchart (part 1) showing an elevator monitoring method according to an embodiment, and is a flowchart including a display procedure for the in-car monitor 13a that is implemented in accordance with a program possessed by the video control device 18 of the elevator monitoring system 1 described using Fig. 1 and Fig. 2. Below, the display procedure for the in-car monitor 13a in the elevator monitoring method will be described along the flowchart of Fig. 7 with reference to Fig. 1, Fig. 2 and other figures.

[0033] [Step S01] In step S01, the video control device 18 acquires information related to car call registration from the elevator control device 17. The information related to car call registration acquired by the video control device 18 is information related to the destination floor registered using the registration button of the car call registration unit 13c.

[0034] [Step S02] In step S02, the video control device 18 causes the car in-car monitor 13a to display the landing video of the destination floor registered in step S01. The landing video of the destination floor is a live video captured by the landing camera 22b installed at the destination floor landing 100f. If multiple destination floors are registered, the car in-car monitor 13a displays the landing video of the destination floor landing 100f registered first.

[0035] [Step S03] In step S03, the video control device 18 determines whether or not car calls for multiple destination floors have been registered based on information from the elevator control device 17, and if it determines that there are (YES), it proceeds to step S04. On the other hand, if it determines that there are not (NO), it proceeds to step S05.

[0036] [Step S04] In step S04, the video control device 18 causes the car in-car monitor 13a to sequentially display, for a predetermined time, images of the landings 100f of the registered destination floors. At this time, the video control device 18 causes the landing image of one destination floor 100f to be displayed for a predetermined time, for example, about 2 to 3 seconds. The video control device 18 also displays the landing images of each destination floor in the order in which the car call registrations were received.

[0037] [Step S05] In the next step S05, the video control device 18 acquires information from the elevator control device 17 that the car door 12 of the car 10 has closed and the car 10 has started moving, and proceeds to the next step S06.

[0038] [Step S06] In step S06, the video control device 18 causes the in-car monitor 13a to display the landing video of the next scheduled arrival floor, including the landing call. The landing video of the next scheduled arrival floor is the landing video of the next destination floor, landing 100f, and is live video captured by the landing camera 22b installed at the destination floor landing 100f. Note that if the destination floor landings are displayed sequentially in step S04, this sequential display ends up in step S06. For this reason, in step S04, there may be some destination floor landings that cannot be displayed due to time constraints before the car doors 12 close, and there may also be some destination floor landings that are displayed for the second time.

[0039] [Step S07] In step S07, the video control device 18 determines whether or not an additional car call registration has been made based on information from the elevator control device 17, and if it determines that an additional car call registration has been made (YES), the process proceeds to step S08. On the other hand, if it determines that no additional car call registration has been made (NO), the process proceeds to step S10.

[0040] [Step S08] In step S08, the video control device 18 causes the car interior monitor 13a to display an image of the landing of the additionally registered destination floor for a predetermined time (for example, about 2 to 3 seconds), and then proceeds to step S09.

[0041] [Step S09] In step S09, the video control device 18 causes the car monitor 13a to display the landing video of the next scheduled arrival floor, including the landing call. The video of the next scheduled arrival floor is the landing video of the next destination floor, which is the live video displayed in step S06.

[0042] [Step S10] In step S10, the video control device 18 determines whether or not an abnormality has occurred in the operation of the elevator 100. If the video control device 18 receives information from the elevator control device 17 that an abnormality has occurred in the operation of the elevator 100, the video control device 18 determines that an abnormality has occurred (YES) and proceeds to step S11. On the other hand, if the video control device 18 does not receive information from the elevator control device 17 that an abnormality has occurred in the operation of the elevator 100, the video control device 18 determines that no abnormality has occurred (NO) and proceeds to step S12.

[0043] [Step S11] In step S11, the video control device 18 displays an image of the interior of the car 10 on each of the remote control center monitor 200 and the control center monitor 300, and also issues a signal (image) notifying the occurrence of an abnormality. This allows the remote control center and the operator at the control center to be notified of the occurrence of an abnormality. The operator who detects the abnormality can forcibly stop the car 10 at the nearest floor if necessary. In addition, the operator can take measures such as being able to talk to passengers in the car 10 via the communication device of the internal operation panel 13 or displaying an operator from the control center on the in-car monitor 13a, thereby giving appropriate instructions to passengers in the car 10 and reassuring them.

[0044] [Step S12] Thereafter, in step S12, the video control device 18 determines whether the elevator has arrived at the next scheduled arrival floor based on information from the elevator control device 17, and if it determines that the elevator has arrived (YES), it proceeds to the next step S13. On the other hand, if it determines that the elevator has not arrived (NO), it returns to step S07 and repeats the subsequent steps. Note that the next scheduled arrival floor when proceeding from step S10 to this step S12 is the next scheduled arrival floor including car calls and hall calls. On the other hand, when proceeding from step S11 to this step S12, depending on the type of abnormality determined in step S10, any hall (e.g., the nearest hall) set for the elevator control device 17 may become the scheduled arrival floor.

[0045] [Step S13] In step S13, the video control device 18 detects that the car door 12 of the car 10 has opened based on the information from the elevator control device 17, and proceeds to the next step S14.

[0046] [Step S14] In step S14, the video control device 18 determines whether all calls have been answered based on the information from the elevator control device 17, and if it determines that all calls have been answered (YES), it ends the process. On the other hand, if it determines that all calls have not been answered (NO), it returns to step S05 and repeats the subsequent steps.

[0047] <Platform monitor display procedure> Fig. 8 is a flowchart (part 2) showing the elevator monitoring method according to the embodiment, and is a flowchart showing the display procedure of the hall monitor 22a implemented in accordance with the program stored in the video control device 18 of the elevator monitoring system 1 described with reference to Figs. 1 and 2. Below, the display procedure of the hall monitor 22a in the elevator monitoring method will be described along the flowchart of Fig. 8, with reference to Figs. 1, 2 and other figures.

[0048] [Step S001] In step S001, the video control device 18 acquires information related to hall call registration from the elevator control device 17. The information related to hall call registration acquired by the video control device 18 is information registered in any of the hall call registration units 22c.

[0049] [Step S002] In step S002, the video control device 18 causes the hall monitor 22a of the floor where the hall call registration was performed in step S001 to display an image of the inside of the car 10. The image of the inside of the car 10 is a live image captured by the in-car camera 13b.

[0050] [Step S003] In step S003, the video control device 18 determines whether or not an abnormality has occurred in the operation of the elevator 100. If the video control device 18 receives information from the elevator control device 17 that an abnormality has occurred in the operation of the elevator 100, it determines that an abnormality has occurred (YES) and proceeds to step S004. On the other hand, if the video control device 18 does not receive information from the elevator control device 17 that an abnormality has occurred in the operation of the elevator 100, it determines that no abnormality has occurred (NO) and proceeds to step S008.

[0051] [Step S004] In step S004, the video control device 18 displays the video of the inside of the car 10 on the remote control center monitor 200 and the control center monitor 300, and also issues a signal (video) notifying the occurrence of an abnormality. This makes it possible to notify the operators of the remote control center and the control center of the occurrence of an abnormality, as in the previous step S11.

[0052] [Step S005] In the next step S005, the video control device 18 stops the display of the video inside the car 10 on the hall monitor 22a, and proceeds to the next step S006. This makes it possible to prevent unnecessary disturbance to the user [p] (see FIG. 6) at the hall 100f by displaying the video inside the car 10 on the hall monitor 22a. Note that this step S005 may be performed as needed, and whether or not to perform it as needed can be set in advance by the manager of the elevator 100.

[0053] [Step S006] In step S006, the video control device 18 determines whether the elevator has arrived at the hall 100f based on information from the elevator control device 17, and if it determines that the elevator has arrived (YES), it proceeds to the next step S007. On the other hand, if it determines that the elevator has not arrived (NO), it repeats step S006 until it determines that the elevator has arrived (YES). The hall that the elevator will arrive at here is the hall registered in step S001, or any hall that the elevator is scheduled to arrive at in the event of an abnormality.

[0054] [Step S007] In step S007, the video control device 18 detects that the car door 12 of the car 10 has opened based on information from the elevator control device 17, and ends the process. Note that in a configuration in which step S005 is not performed, after detecting that the door has closed in step S007, the video control device 18 stops displaying the image inside the car 10 on the hall monitor 22a of the hall registered in step S001, and then ends the process.

[0055] [Step S008] On the other hand, step S008 is a step to which the process proceeds when it is determined in step S003 that no abnormality has occurred (NO). In this step S008, the video control device 18 determines whether the car 10 has arrived at the hall registered in step S001 based on information from the elevator control device 17, and if it is determined that the car 10 has arrived (YES), the process proceeds to the next step S009. On the other hand, if it is determined that the car has not arrived (NO), the process returns to step S003, and the subsequent steps are repeated while continuing to display the car interior image on the hall monitor 22a.

[0056] [Step S009] In step S009, the video control device 18 detects that the car door 12 of the car 10 has opened based on the information from the elevator control device 17, and proceeds to the next step S010.

[0057] [Step S010] In step S010, the video control device 18 stops the display of the video inside the car on the hall monitor 22a of the hall registered in step S001, and ends the process.

[0058] <Display procedure during maintenance> Next, the display procedure during elevator maintenance work will be described. With reference to Figures 1 and 2, when performing maintenance work, the worker switches the operation mode of elevator 100 from normal operation mode to maintenance mode by operating an operation switch (not shown) on in-car operation panel 13.

[0059] As a result, the video control device 18 first stops the display of images on all hall monitors 22a. Then, the video control device 18 displays images captured by maintenance cameras such as the car-top camera 14, the car-bottom camera 15, and the pit camera 16 on the car-inside monitor 13a. Furthermore, the video control device 18 switches between displaying images captured by the car-top camera 14, the car-bottom camera 15, and the pit camera 16 on the car-inside monitor 13a, depending on a combination of button operations performed by the worker on the car-inside operation panel 13.

[0060] In addition, when an operator presses and holds the button on the hall call registration section 22c of the hall operation panel 22 at any hall 100f, the video control device 18 displays images captured by maintenance cameras such as the car-top camera 14, the car-bottom camera 15, and the pit camera 16 only on the hall monitor 22a of that hall operation panel 22.

[0061] This allows the worker to check the video captured by the maintenance camera on the car monitor 13a or hall monitor 22a.

[0062] Furthermore, when a predetermined time has elapsed since the operation switch (not shown) was switched to the maintenance mode, or when the button on the hall call registration unit 22c is pressed and held again, the video control device 18 stops the display on the car monitor 13a and the hall monitor 22a and switches the elevator operation mode from the maintenance mode to the normal operation mode.

[0063] Note that switching of the elevator operation mode is not limited to being performed by operating an operation switch, but may be performed by connecting a maintenance computer to a connector on the hall operation panel 22 on any floor (for example, the lowest floor) and operating the connected maintenance computer. In this case, the elevator operation mode is switched to the normal operation mode when a certain time has elapsed since switching to the maintenance mode.

[0064] Effect of the embodiment According to the embodiment described above, a passenger [p1] (see FIG. 4) in the elevator car 10 can check the state of the hall 100f of the destination floor he or she specified on the car monitor 13a in advance. Furthermore, a user [p] (see FIG. 6) waiting at the hall 100f can check the state of the interior of the elevator car 10 he or she is about to board on the hall monitor 22a in advance. This allows the passenger [p1] and the user [p1] time to prepare for an unexpected event, thereby improving the security of the elevator 100 and safety during use. In contrast, for example, in a configuration in which the hall door 21 and the car door 12 are provided with vision glass, the state of the hall 100f of the destination floor and the state of the interior of the elevator car 10 cannot be seen until the elevator car 10 arrives at the destination floor, and therefore it is not possible to prepare for an unexpected event.

[0065] Furthermore, in a configuration in which vision glass is provided, the inner wall of the running path 100a can be seen from inside the elevator 10, and the inner wall of the running path 100a, the upper and lower parts of the elevator 10, and various equipment installed inside the running path 100a can be seen from the landing 100f, but according to this embodiment, such poor appearance can be eliminated.

[0066] The hall monitor 22a at an arbitrarily set reference floor may always display the image inside the car 22a regardless of whether a hall call is registered. Here, the reference floor is, for example, a floor where the car 10 is kept waiting when no call is registered, and is typically a floor with the most registered calls, such as a floor where the entrance or lobby of the building where the elevator 100 is installed is located. This makes it easier for many people to monitor the situation inside the car 10. In this case, the image control device 18 stops the display of the image inside the car 10 on the hall monitor 22a at the reference floor only when the elevator control device 17 determines that an abnormality has occurred in the operation of the elevator 100.
