  Therefore, the present invention can predict the arrival of the car and the subsequent door opening by a person staying in the vicinity of the door in the floor when the elevator is stood remotely, and can perform a trial operation with opening and closing of the door. Provide a remote monitoring system.

  The elevator remote monitoring system of the present invention has a car that can be stopped at a plurality of levels of a building and has a door that opens and closes at the level where the building is stopped, and the operation of the car can be controlled, and at least information on an abnormality related to opening and closing of the door An elevator having a control microcomputer to be stored; a notification device installed at each of the plurality of levels; and a terminal connectable to the control microcomputer, wherein the terminal can be set to an inspection mode for inspecting the elevator. When the inspection mode is set, the control microcomputer instructs the control microcomputer to stop the car from the plurality of floors, and the notification device stops at the level where the car is installed at least in the inspection mode. The notification is made when the door of the car is opened.

  In the elevator remote monitoring system described above, in the inspection mode, the car stops at the level where the notification device is installed, and the notification device notifies when the car door is opened. The person can predict the arrival of the car and the opening of the door (for example, when a floor door that opens and closes in conjunction with the door of the car is provided in the floor). Accordingly, when the elevator is stood remotely, it is possible to make a person staying near the door in the floor predict the arrival of the car and the subsequent door opening, and to perform a trial operation that involves opening and closing the door.

  The elevator remote monitoring system includes a hall call device installed at each of the plurality of floors, and the terminal calls the car by the hall call device during the inspection mode, and the call Except for the level at which the door of the car is opened and closed, the level at which the car is stopped may be indicated from the plurality of levels.

  According to this configuration, only the level where the car is not called by the hall call device is instructed to stop the car, and the car is called by the hall call device and the car door is opened and closed. By using this opening / closing result for inspection without instructing stoppage of the door, it is possible to check opening / closing of the doors for all the floors provided in the building.

  In the elevator remote monitoring system, when information regarding an abnormality is stored in the control microcomputer during the inspection mode, the information regarding the abnormality stored in the control microcomputer may be acquired from the control microcomputer.

  According to such a configuration, when an abnormality occurs in the elevator in the inspection mode, the terminal automatically acquires information on the abnormality stored in the control microcomputer, so that the information on the abnormality can be confirmed from the terminal.

  The elevator remote monitoring system includes an imaging device capable of imaging the open / closed states of the doors in each of the plurality of levels, and the terminal at least at the timing when the information related to the abnormality is stored in the control microcomputer. You may acquire the image imaged with the imaging device.

  According to such a configuration, when an abnormality occurs in the elevator in the inspection mode, the terminal automatically acquires a captured image of the open / closed state of the door, so that the captured image can be confirmed from the terminal.

  In the elevator remote monitoring system, the terminal can instruct the control microcomputer to open and close the door of the car that is stopped at the level in the inspection mode, and the notification device is provided with the notification device. Further, it is possible to notify that the car has arrived at the level, and when the door of the stopped car is opened in the inspection mode, it may be notified that the car has arrived.

  According to such a configuration, since the notification device notifies even when the door of the stopped car is opened, a person staying near the door in the hierarchy can predict the opening of the car by this notification. Thus, when the elevator is stood remotely, a person staying in the vicinity of the door of the floor can be predicted to open the car, and a trial operation involving opening and closing of the door can be performed.

  As described above, according to the present invention, when the elevator is remotely patrolled, a person staying in the vicinity of the door of the floor is predicted to arrive at the car and then open, and a trial operation involving opening and closing of the door is performed. It is possible to provide a remote monitoring system that can.

  Hereinafter, a remote monitoring system for an elevator according to the present invention (hereinafter simply referred to as a remote monitoring system) will be described. The remote monitoring system is a system that remotely monitors the operation state of the elevator and performs a trial operation of the elevator remotely when checking the operation of the elevator. In this remote monitoring system, when an elevator door is opened and closed, when the car door is opened, a notification device such as an indicator notifies the same as when the car door is opened during normal operation. Thus, in this remote monitoring system, a car staying in the vicinity of the door at the landing (hierarchy) during the inspection of the opening / closing of the elevator doors and the subsequent door opening (for example, the car door on the hierarchies) In the case where a hierarchical door that opens and closes in conjunction with the door is provided, it can be predicted that the hierarchical door will open.

  As shown in FIG. 1, the remote monitoring system includes an elevator 2 having a control microcomputer 20 and a car 21, and a monitoring terminal (terminal) 4 that can be connected to the control microcomputer 20. The remote monitoring system 1 according to this embodiment includes a remote monitoring unit 5 provided between the control microcomputer 20 and the monitoring terminal 4.

  In the remote monitoring system 1 of this embodiment, the building 3 in which the elevator 2 is installed is, for example, a three-story building. Each level (each landing) 30 in the building 3 (see FIG. 2 which is a block diagram of each level 30 in the building 3 in FIG. 1 and FIG. 3 which is a diagram showing each level 30) includes an indicator (notification device) 300, A hall call button (landing call device) 310 and a hierarchical door (landing door) 320 that opens and closes in conjunction with the car door 210 are provided.

  In FIG. 1, one monitoring terminal 4 is shown, but the remote monitoring system 1 of this embodiment includes a plurality of monitoring terminals 4. Moreover, since the elevator 2 is connected to each monitoring terminal 4 via the communication system R1, the remote monitoring system 1 of the present embodiment includes a plurality of elevators. For example, the communication system R1 can communicate with the monitoring terminal 4 via the remote monitoring unit 5 and the telephone line in order from the control microcomputer 20, and conversely from the monitoring terminal 4 via the telephone line and the remote monitoring unit 5. Thus, the communication system can communicate with the elevator 2.

  The elevator 2 has a control microcomputer 20 and a car 21 connected to the control microcomputer 20.

  The car 21 can move up and down in a hoistway provided in the building 3 where the elevator 2 is installed, and can be stopped at a plurality of levels 30 of the building 3 (for example, all levels 30 provided in the building 3). is there. In addition, the car 21 includes a car door 210 that opens and closes at the stopped level 30 and a door at a plurality of levels 30 (hereinafter, the “car door 210 and the level door 320” are simply referred to as “door”). And a camera (imaging device) 211 capable of imaging the open / closed state of the. In the remote monitoring system 1 of the present embodiment, in addition to the car door 210 and the camera 211, the car 21 includes a button (not shown) that can raise and lower the car 21 and open / close the car door 210 by operation, and the elevator 2. And various sensors (not shown) capable of outputting the detection result as a signal relating to the operation state of the elevator 2. This sensor can output various signals corresponding to the operation status of the elevator 2 (for example, raising and lowering of the car 21, opening and closing of the car door 210, and the position of the car 21).

  The camera 211 is installed in the car 21, for example. Specifically, the camera 211 is arranged on the ceiling in the car 21 and images the inside of the car 21 and the entrance / exit of the car 21 and the hierarchy over time. The camera 211 can image the level 30 when the car 21 stops at the level and the car door 210 and the level door 320 are open.

  The camera 211 is connected to the monitoring terminal 4 via the remote monitoring unit 5. As a result, the camera 211 can output information related to an image (moving image or still image) obtained by imaging opening and closing of the door to the monitoring terminal 4. In the car 21, for example, one monitoring camera is provided for monitoring the inside of the car 21 and the entrance / exit of the car 21 and the level 30. In the remote monitoring system 1 of the present embodiment, A surveillance camera is used.

  In the remote monitoring system 1 of the present embodiment, the camera 211 has an image storage unit (not shown) that stores captured images. The image storage unit of the camera 211 can be rewritten.

  In the remote monitoring system 1 of the present embodiment, the control microcomputer 20 always accepts output of information related to the operation status of the elevator 2 by a sensor (a sensor provided in the car 21). The control microcomputer 20 outputs information on the operation status of the elevator 2 by a sensor (a sensor provided in the car 21), thereby raising the car 21, lowering the car 21, opening / closing the car door 210, and the level 30 of the car 21. Recognize arrival at

  Further, when the information is output from the sensor, the control microcomputer 20 performs, for example, car door opening / closing information, button operation in the car, and car position based on the output information. An event code indicating information or the like is stored. Specifically, the control microcomputer 20 stores the event code in association with the occurrence date and time. The event code includes an event code indicating a failure (for example, an event code indicating an abnormality in the elevator 2 such as a car door or a hierarchy door failure).

  Furthermore, in the remote monitoring system 1 of the present embodiment, the control microcomputer 20 can be switched between a normal operation mode and an inspection mode for inspecting the elevator 2 according to an instruction from the monitoring terminal 4. In the normal operation mode, the control microcomputer 20 controls the car 21 and the like in accordance with, for example, a user operation (a hall call operation at the level 3 or a destination floor instruction operation within the car 21). In the hall call operation, the user or the like calls the car 21 using the hall call button (the hall call device) 310 provided on the level (the hall 30), and thus the floor 30 where the user or the like stays. This is an operation for moving the car 21. In the inspection mode, for example, the control microcomputer 20 controls the car 21 and the like in accordance with instructions from the monitoring terminal 4 in addition to user operations. Thereby, in the inspection mode, it can be inspected whether or not there is an abnormality in the opening and closing of the door.

  When the control microcomputer 20 is set to the normal operation mode, the level 30 corresponding to the operated hall call button 310 (hereinafter referred to as “call level 30”) is operated as needed by operating the hall call button 310. ) Move the car 21 toward Specifically, in the normal operation mode, the control microcomputer 20 moves the car 21 toward the call hierarchy 30 when the call hierarchy 30 is different from the hierarchy 30 where the car 21 is stopped. When the floor 30 where the car 21 is stopped matches, the car 21 is kept stopped at the call floor 30. Further, the control microcomputer 20 opens the car door 210 in a state where the car 21 is called and stopped at the level 30. At this time, as the car door 210 is opened (in conjunction with the opening of the car door 210), the level door 320 is also opened. The control microcomputer 20 closes the door when the user gets into the car 21 and operates the button.

  When the control microcomputer 20 is set to the inspection mode, when receiving an instruction from the monitoring terminal 4, the control microcomputer 20 moves the car 21 toward the target level as necessary. Specifically, in the inspection mode, the control microcomputer 20 changes the car 21 to the target level 30 when the target level 30 indicated by the monitoring terminal 4 is different from the level 30 where the car 21 is currently stopped. When the target level 30 indicated by the monitoring terminal 4 matches the level 30 where the car 21 is stopped, the car 21 is kept stopped at the target level 30. Further, the control microcomputer 20 closes after the car door 210 is opened in a state where the car 21 is stopped at the target level. At this time, the level door 320 is also opened and closed in conjunction with the opening and closing of the car door 210. In other words, as the car door 210 is opened, the level door 320 is also opened, and as the car door 210 is closed, the level door 320 is also closed.

  The control microcomputer 20 outputs a signal to that effect to the indicator 300 when the car door 210 is opened at least in the inspection mode. In the remote monitoring system 1 of this embodiment, the control microcomputer 20 outputs a signal to that effect to the indicator 300 when the car door 210 is opened in both the normal operation mode and the inspection mode. Specifically, in addition to opening the car door 210, the control microcomputer 20 sends a signal to that effect to the indicator 300 when the car 21 is moving up and down, when the car 21 is stopped, and when the car door 210 is closed. Output.

  More specifically, the control microcomputer 20 gives a signal to that effect when the car 21 is rising, a signal to that effect when the car 21 is descending, and the case where the car 21 is stopped. Are output to the indicator 300 respectively. Further, the control microcomputer 20 outputs a signal to that effect to the indicator 300 when the door is opened, and outputs a signal to that effect when the door is closed. Further, when the car 21 arrives at the level 30, the control microcomputer 20 outputs a signal to that effect to the indicator 300.

  Note that the control microcomputer 20 stores information on abnormality in itself in both the normal operation mode and the inspection mode. Specifically, when the control microcomputer 20 detects that an abnormality related to the opening / closing of the door has occurred in the inspection mode, a sensor provided in the car 21 indicates to itself “an event indicating a failure of the car door 210 or the hierarchical door 320. "Code" is memorized.

  The remote monitoring unit 5 always receives an output of a signal (for example, an event code) from the control microcomputer 20, and when the signal is output from the control microcomputer 20, this signal and an elevator from which this signal is output are related. Information (for example, the elevator identification number of the elevator 2) is output to the monitoring terminal 4.

  For example, the monitoring terminal 4 of the present embodiment monitors a large number of elevators installed in a plurality of areas, and is installed in a monitoring center or the like that is a building apart from the target elevator. A supervisor (operator) is resident in the monitoring center of this embodiment.

  Information (for example, an elevator machine number) and a signal regarding the elevator of the output source are output from the control microcomputer 20 to the monitoring terminal 4 via the communication system R1. Moreover, the monitoring terminal 4 has the display part 40 which can display the content (for example, event code) of the signal (for example, event code | cord | chord) from the control microcomputer 20, for example, the information (for example, elevator machine number) of the elevator 2 of the output source. The display unit 40 is, for example, a display. Furthermore, the monitoring terminal 4 has an input unit 41 that can be operated by a monitoring staff. The input unit 41 is, for example, a keyboard.

  The monitoring terminal 4 can set the elevator 2 to the inspection mode. In the remote monitoring system 1 of this embodiment, the monitoring terminal 4 will instruct | indicate this switching to the control microcomputer 20, if switching operation with normal operation mode and inspection mode is performed via the input part 41 by the monitoring person. Specifically, the monitor performs a switching operation from the normal operation mode to the inspection mode via the input unit 41 at an arbitrary timing. In addition, when the inspection about the opening and closing of the door is completed by the process described later, the monitoring person performs a switching operation from the inspection mode to the normal operation mode via the input unit 41. When the switching operation to the inspection mode or the normal operation mode is performed, the monitoring terminal 4 instructs the control microcomputer 20 to perform this switching.

  In the normal operation mode, the monitoring terminal 4 outputs information (for example, elevator number) of the output source and an abnormality signal from the control microcomputer 20 on the display unit 40 (for example, information on the output source elevator 2). The elevator machine number) and the content of the abnormal signal (for example, an event code indicating the abnormality) are displayed to notify the monitoring personnel of the abnormality related to the elevator 2. By checking this notification, the monitoring person can grasp the abnormality of the elevator 2 and can operate the input unit 41 to request the engineer to be dispatched as necessary.

  In the inspection mode (when the elevator 2 is set to the inspection mode), the monitoring terminal 4 instructs the control microcomputer 20 to the level 30 for stopping the car 21. Specifically, when the monitoring terminal 4 is operated to perform “door inspection” via the input unit 41 by the monitoring person in the inspection mode, the opening and closing of the door 210 is completed in all the levels 30 of the building 3. Until then, the control microcomputer 20 is instructed to “stop the car 21 after moving it one level and then open and close the car door 210”. The monitoring terminal 4 checks the presence / absence of a hall call from the hall call button 310 every time the car door 210 is opened and closed in each level 30.

  More specifically, the monitoring terminal 4 controls to open and close the car door 210 when the elevator 21 installed in the building 3 is set to the inspection mode in a state where the car 21 is stopped at the floor 30A on the first floor. The microcomputer 20 is instructed, then the car 21 is moved to the second floor 30B and then stopped, the control microcomputer 20 is instructed to open and close the car door 210, and finally the car 21 is moved to the third floor 30C. The control microcomputer 20 is instructed to stop and open the car door 210 after being moved. By these series of processes, the inspection about the opening and closing of the doors is completed in each of the levels 30A, 30B, and 30C.

  In the remote monitoring system 1 of the present embodiment, the monitoring terminal 4 can instruct the control microcomputer 20 to open and close the car door 210 of the car 21 that is stopped at the level 30 in the inspection mode. In the remote monitoring system 1 according to the present embodiment, when the car 21 is called by the hall call button 310 during the inspection mode, the car 21 is called by the hall call button 310 and the door is opened and closed by the call. The tier 30 to stop the car 21 is instructed except the tier 30 to be operated.

  Specifically, in the monitoring terminal 4, during the inspection mode, the car 21 is called by the operation of the landing call button 310 by the user and the door is opened and closed by the call (for example, the user gets into the car 21). The tier 30 and the tier 30 for stopping the car 21 are instructed except for the tier and the tier 30 to which the car 21 has moved by the operation of the user who has entered the car 21 In other words, the monitoring terminal 4 uses the opening / closing result of the door for the inspection of the level 30 where the car 21 is called by the hall call button 310 and the door is opened and closed by the call, and the level 30 other than the level 30 Inspection is performed by stopping 21 and opening and closing the door. Thereby, the inspection about opening and closing of the door is completed for all the hierarchical doors 30 provided in the building 3.

  In the remote monitoring system 1 of the present embodiment, the monitoring terminal 4 repeatedly instructs the control microcomputer 20 to “stop the car 21 after moving it one level and open / close the car door 210”. Each time the opening / closing of the car door 210 is completed, the presence / absence of a hall call from the hall call button 310 is confirmed.

  More specifically, the monitoring terminal 4 checks the presence or absence of a landing call when the elevator 21 installed in the building 3 is set to the inspection mode in a state where the car 21 is stopped at the floor 30A on the first floor. When the car 21 is called by the hall call button 310 installed on the third floor 30C, the car 21 is temporarily moved to the third floor 30C and then stopped, and the control microcomputer 20 is instructed to open the car door 210. . In this case, when a user who has entered the car 21 from the third floor 30C operates a button in the car 21 to move the car 21 to the first floor, the monitoring terminal 4 again moves the car 21 to the first floor 30A. The control microcomputer 20 is instructed to stop and open the car door 210. Thereafter, the presence / absence of a hall call is confirmed, and if the car 21 is not called by the hall call button 310, the car 21 is moved to the second floor 30B and then stopped, and the control microcomputer 20 is instructed to open and close the car door 210. To do. Thereby, the inspection about opening and closing of the door is completed.

  On the other hand, when the elevator 21 installed in the three-story building 3 is set to the inspection mode in a state where the car 21 is stopped on the first floor 30A, the monitoring terminal 4 is installed on the third floor 30C. When the car 21 is called by the hall call button 310, the control microcomputer 20 is instructed to stop the car 21 after moving it to the third floor 30C and to open the car door 210. Thereafter, the monitoring terminal 4 moves the car 21 to the second floor 30B when the user who has entered the car 21 from the third floor 30C operates the button to move the car 21 to the second floor in the car 21. The control microcomputer 20 is instructed to stop and open the car door 210 later. Thereby, the inspection about opening and closing of the door is completed.

  In the remote monitoring system 1 of the present embodiment, when the inspection of the door is completed, the monitoring terminal 4 instructs the control microcomputer 20 to switch from the inspection mode to the normal operation mode, for example, by the operation of the monitoring person. Specifically, when the inspection of the door is completed, the operation of this observer is a completion message displayed on the display unit 40 (for example, “Door inspection is complete. Do you want to switch to the normal operation mode?”). To the normal operation mode (for example, an input operation of “Yes”).

  Further, in the remote monitoring system 1 of the present embodiment, the monitoring terminal 4 stores the abnormality stored in the control microcomputer 20 when information related to the abnormality (for example, an event code indicating abnormality) is stored in the control microcomputer 20. Information (for example, an event code indicating abnormality) is acquired from the control microcomputer 20. Specifically, when the inspection mode is completed, the monitoring terminal 4 acquires all event codes stored in the control microcomputer 20 between the start of the inspection mode and the completion of the inspection mode. Displays the contents of the acquired event code.

  Furthermore, in the remote monitoring system 1 of the present embodiment, the monitoring terminal 4 stores the timing when information related to an abnormality (for example, an event code indicating an abnormality) is stored in the control microcomputer 20 during the inspection mode. The image picked up in (1) is acquired from the camera 211. Specifically, when the inspection mode is completed, the monitoring terminal 4 acquires an image stored in the camera 211 between the start of the inspection mode and the completion of the inspection mode. In addition, an image is displayed.

  In the remote monitoring system 1 of this embodiment, the indicator 300 in each level 30 is arrange | positioned on the wall surface located above the level door 320, as shown in FIG. The indicator 300 is a display, for example, and can communicate with the control microcomputer 20. In addition, the indicator 300 notifies when the car door 210 of the car 21 that stops at the level 30 where it is installed opens at least in the inspection mode.

  Specifically, when the signal indicating opening / closing of the door is output from the control microcomputer 20, the indicator 300 displays a message regarding door opening / closing (for example, “Please note that the door opens.” "Please note that will close." Is displayed. Further, when a signal indicating that the car 21 is moving up or down is output from the control microcomputer 20, the indicator 300 indicates an upward arrow or a downward arrow and the nearest hierarchy 30 (for example, when the nearest hierarchy 30 is the second floor). “2”) is displayed. When the signal indicating that the car 21 is stopped at the level 30 is output from the control microcomputer 20, the indicator 300 displays the level 30 (for example, “2” when stopped at the second floor).

  Further, when a signal indicating that the car 21 has arrived at the level 30 is output from the control microcomputer 20, the indicator 300 indicates that the car 21 has arrived (for example, a message “the car has arrived”). Is displayed. The indicator 300 is also in the inspection mode when a signal for opening the car door 210 is output immediately after the signal indicating that the car 21 is stopped at the level 30 is output from the control microcomputer 20. A message indicating that the car 21 has arrived (for example, a message that “the car has arrived”) is displayed.

  In the remote monitoring system 1 of the present embodiment, the hall call button 310 in each level 30 is arranged on the wall surface on the right side of the level door 320 as shown in FIG.

  In the remote monitoring system 1 described above, in the inspection mode, the car 21 stops at the level 30 where the indicator 300 is installed, and the indicator 300 notifies when the car door 210 is opened. The person who is doing can predict the arrival of the car 21 and the door opening (for example, the opening of the level door 320) by the notification of the indicator 300. As a result, when the elevator 2 is stood remotely, a person staying near the door in the level 30 predicts the arrival of the car 21 and the subsequent door opening, and is accompanied by opening and closing of the car door 210 and the level door 320. Commissioning can be performed.

  In the remote monitoring system 1 according to the present embodiment, the level 30 other than the level 30 where the car 21 is called is instructed to stop the level 30 and the door is opened and closed, and the level 30 where the car 21 is called. With respect to all the floors 30 provided in the building 3 by performing inspection using the opening / closing results of the car door 210 and the floor door 320 by calling the car 21 without instructing the floor 30 to stop, The door opening and closing can be inspected.

  Further, in the remote monitoring system 1 of the present embodiment, when an abnormality occurs in the elevator 2 in the inspection mode, the monitoring terminal 4 automatically acquires an event code (information regarding abnormality) indicating the abnormality stored in the control microcomputer 20. Therefore, the event code (information related to the abnormality) indicating this abnormality can be confirmed from the monitoring terminal 4. Thereby, for example, the monitoring person can grasp the contents of the abnormality by checking the event code. As a result, it is possible for the supervisor to dispatch a technician or the like to the site (the elevator 2 in which an abnormality has occurred) as needed to deal with the trouble of the elevator 2.

  Furthermore, in the remote monitoring system 1 according to the present embodiment, when an abnormality occurs in the elevator 2 in the inspection mode, the monitoring terminal 4 automatically acquires captured images of the open / closed state of the car door 210 and the hierarchical door 320. This captured image can be confirmed from 4. Thereby, for example, the monitor can analyze the cause of the abnormality based on the captured image.

  In the remote monitoring system 1 of the present embodiment, when the monitoring terminal 4 performs the door opening / closing inspection, the “car 21 is moved one level until the doors 210 are completely opened and closed at all the levels 30 of the building 3. The control microcomputer 20 is repeatedly instructed to “stop later and open / close the car door 210”, and at each level 30, each time the opening / closing of the car door 210 is completed, the presence / absence of a hall call from the hall call button 310 is confirmed. Yes. Therefore, the user can use the elevator 2 even in the inspection mode.

  In the remote monitoring system 1 of the present embodiment, since the indicator 300 notifies even when the car door 210 of the stopped car 21 is opened, a person staying in the vicinity of the door in the hierarchy 30 can notify the car 21 by this notification. Can be predicted. Accordingly, when the elevator 2 is stood remotely, a person staying near the door in the level 30 predicts the opening of the car 21 and performs a trial operation with opening and closing of the car door 210 and the level door 320. Can do.

  The remote monitoring system of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention. For example, the configuration of another embodiment can be added to the configuration of a certain embodiment, and a part of the configuration of a certain embodiment can be replaced with the configuration of another embodiment. Furthermore, a part of the configuration of an embodiment can be deleted.

  For example, the monitoring terminal 4 uses the car 21 for all of the plurality of floors 30 (all of the plurality of floors 30 including the floor 30 in which the car 21 is called by the hall call button 310 and the door is opened / closed by a call) in the inspection mode. May be instructed to stop the door 30, and door opening / closing may be checked for all of the plurality of floors 30.

  Further, when information related to the abnormality is stored in the control microcomputer 20 during the inspection mode, the monitoring terminal 4 acquires the information related to the abnormality from the control microcomputer 20 or acquires an image captured by the camera 211. However, it is not necessary to acquire information and images regarding this abnormality. For example, the monitoring terminal 4 may acquire an image in response to an instruction from the monitoring person when it is determined that the monitoring person who has confirmed the information related to the abnormality by the display unit 40 is necessary. When the above information is stored in the control microcomputer 20, information regarding an abnormality or an image may be acquired.

  Furthermore, in the inspection mode, the monitoring terminal 4 instructs the control microcomputer 20 to “move and stop the car 21 one level at a time and open and close the car door 210 each time the car 21 stops”. It is not necessary to confirm the presence or absence of a hall call until the opening and closing of the car doors 210 in all the floors 30 provided in the building 3 is completed.

  The indicator 300 is also used when the signal indicating that the car door 210 is opened is output immediately after the signal indicating that the car 21 is stopped at the level 30 is output from the control microcomputer 20 in the inspection mode. Was displayed (for example, the message “The basket is arriving”), but instead of this message, a message about opening and closing the door (for example, “Please note that the door will open. Message ") may be displayed.

  The notification device provided in the hierarchy 30 may be at least one of an indicator 300, a speaker, a hall lantern, and the like. For example, the speaker notifies at least one of raising / lowering of the car 21, arrival of the car 21, and opening / closing of the door. When the notification device includes a speaker, the information to be notified is audio information such as an audio announcement, a gong sound, and a chime sound. The hall lantern notifies the arrival of the car 21. The indicator 300 may be disposed above the car jump button 310 or the like. Whatever the notification device is configured, in the inspection mode, when the car door 210 that stops at the floor 30 where the notification device is installed is notified, when the elevator 2 is stolen remotely, A person staying near the door at level 30 predicts the arrival of the car 21 and the subsequent door opening (for example, the level door 320 that opens and closes in conjunction with the car door 210), and opens and closes the car door 210 and the level door 320. A test run involving

  In addition, the hall call button (the hall call device) 310 may be installed at a part of the plurality of levels 30 in the building 3 in addition to being installed at each level 30.

  The control microcomputer 20 stored information on abnormality in itself during the inspection mode. However, when the fact that an abnormality has occurred in the elevator 2 is input from a sensor provided in the car 21, the information on the abnormality is controlled. You may output to the monitoring terminal 4 different from the microcomputer 20, a storage server, etc. In this case, instead of the control microcomputer 20 storing information relating to the abnormality, the monitoring terminal 4 or the like may store information relating to the abnormality output from the control microcomputer 20. Moreover, in this case, the monitoring terminal 4 should just extract the information regarding abnormality in the inspection mode memorize | stored in self.

  Similarly, the camera 211 may output a captured image in the inspection mode to the monitoring terminal 4 or a storage server. In this case, instead of the camera 211 itself storing the captured image, the monitoring terminal 4 or the like may store the image output from the camera 211. In this case, the monitoring terminal 4 may acquire the “image captured at the timing when information related to the abnormality in the inspection mode is stored” stored in the monitoring terminal 4.

  The camera 211 is not limited to the surveillance camera, and may be another camera. In addition, the camera 211 may be installed in a different place (for example, each level 30) from the inside of the car 21.

  In the remote monitoring system 1 of the above-described embodiment, the door operator is inspected for opening and closing by switching to the inspection mode via the input unit 41 and performing “inspection of the door” by the monitoring person. The date and time of switching to the mode and the contents of the inspection (such as “door inspection”) may be registered in a schedule, and the inspection mode may be automatically switched to the inspection mode and the door open / closed at the scheduled date and time.

  The monitoring terminal 4 has instructed the control microcomputer 20 to perform the switching operation when the inspection of the door opening / closing is completed and the monitoring person performs the switching operation to the normal operation mode. It may be set in advance to switch to the normal operation mode.

  Furthermore, in the remote monitoring system 1 of the above embodiment, although not particularly set, a hierarchy 30 that does not perform automatic inspection of door opening / closing among the plurality of hierarchy 30 in the building 3 may be set. In this case, regarding the level 30 where automatic door opening / closing inspection is not performed, a technician dispatched to the site (building 3) may perform door opening / closing inspection or may not perform door opening / closing inspection itself.

  The remote monitoring system 1 of the above embodiment includes a plurality of remote monitoring units 5, but may include a single remote monitoring unit 5. In this case, the remote monitoring system 1 may include one elevator.

  The communication system R1 may include the Internet instead of the telephone line. For example, as shown in FIG. 4, the communication system R1 can communicate with the monitoring terminal 4 sequentially from the elevator 2 via the remote monitoring unit 5 and the Internet, and conversely from the monitoring terminal 4 to the Internet and the remote monitoring unit. 5 may be a communication system capable of communicating with the elevator 2 via the communication line 5.

  Instead of the monitoring terminal 4, a terminal different from the monitoring terminal 4 (for example, a portable terminal (terminal) 6 that can be connected to the control microcomputer 20 via the Internet as shown in FIG. 5) An instruction of the hierarchy 30 for stopping the car 21 with respect to 20 may be performed. The portable terminal 6 is, for example, a terminal such as a PDA (Personal Digital Assistant), a smartphone, or a laptop computer, and is carried by a technician who can deal with an abnormality in the elevator 2.

  The mobile terminal 6 stores the information output from the monitoring terminal 4 (for example, information related to the transfer from the monitoring terminal 4 or a request for remote response), the event code indicating the abnormality, and the camera 211 at the timing when the event code is stored. It has a display unit 60 capable of displaying a captured image and the like, and an input unit 61 capable of inputting specification information by a technician. The display unit 60 is, for example, a display. The input unit 61 is, for example, an input key or a keyboard. When the mobile terminal 6 includes a touch panel display, this display serves as the display unit 60 and the input unit 61.

  When the mobile terminal 6 sets the inspection mode, etc., the door may be opened and closed by remotely registering the operation of the button in the car 21.
