Description

  The present invention relates to a remote monitoring system for remotely monitoring a lifting device such as an elevator or an escalator.

  2. Description of the Related Art Conventionally, a remote monitoring system that monitors an operation state of a lifting device has been provided. The remote monitoring system includes a lifting device including a control microcomputer for controlling the operation, and a monitoring terminal communicably connected to the control microcomputer of the lifting device for remotely monitoring the operation of the lifting device ( Patent Document 1).

  In such a remote monitoring system, when the control microcomputer determines that the operation status of the elevating device is abnormal, the monitoring terminal of the monitoring center stays at the monitoring center based on a signal from the elevating device (control microcomputer). The operating status of the elevating device (operation stop, etc.) is notified to the monitoring personnel. Along with this, the supervisor requests the maintenance worker to be seconded to the site.

  The elevating device is normally operated automatically, but may be manually operated by a maintenance worker during maintenance work. In addition, the maintenance worker may intentionally operate the lifting device so that the operation status of the lifting device becomes abnormal during maintenance work, for example, for operation confirmation. However, the control microcomputer can detect an abnormal operation of the elevating device during the maintenance work, so that the abnormal operation of the elevating device is detected as an abnormality of the elevating device, and the elevating device is abnormal with respect to the monitoring terminal. There was a risk of issuing a signal to that effect.

  In order to avoid this unnecessary notification, the lifting device is provided with a maintenance switch capable of prohibiting the control microcomputer from issuing a signal (signaling that the lifting device is abnormal). The maintenance switch is a mechanical switch. The ON operation prohibits the control microcomputer from issuing a signal indicating that the elevating device is abnormal, and the OFF operation indicates that the elevating device is abnormal for the control microcomputer. Allows the signal to be issued.

  Before the maintenance work of the lifting device is started, the maintenance operator manually turns on the maintenance switch, so that even if the lifting device during the maintenance operation intentionally causes an abnormality, the monitoring terminal can notify the monitoring personnel. There is no notification of abnormality of the lifting device. Also, after the maintenance work of the lifting device is completed, the maintenance operator manually turns off the maintenance switch, and when an abnormality occurs in the normally operating lifting device, the monitoring terminal notifies the monitoring personnel of the failure of the lifting device. Notify.

  However, as described above, the maintenance switch is a mechanical switch that requires a manual operation at the time of the ON operation or the OFF operation, and thus the maintenance worker may forget such an operation. If the maintenance worker forgets to turn on the maintenance switch before the start of maintenance, the control microcomputer sends a signal indicating that the lifting device is abnormal when an intentional abnormality occurs in the lifting device during maintenance. Is issued, and the monitoring terminal notifies the monitoring personnel of the abnormality of the elevating device.

  Therefore, the present invention provides a remote monitoring system for a lifting device capable of suppressing erroneous notification regarding an abnormality of the lifting device.

  A remote monitoring system according to the present invention includes a control microcomputer capable of outputting an abnormal signal and an elevating device having an image pickup device, an image recognition unit connected to the image pickup device, and a control microcomputer connected to the control microcomputer, based on the abnormal signal. An output unit capable of notifying an abnormality, wherein the image recognition unit stores information on characteristics of the maintenance worker, and information of an image received from the imaging device is stored in the storage unit. A processing unit that determines whether or not the image has the information on the feature, and when the processing unit determines that the information of the image has the information on the feature, prohibits the notification by the output unit. It is characterized by the following.

  According to the above remote monitoring system, when it is determined that the maintenance worker is staying around the elevating device based on the image from the imaging device (when the maintenance worker is performing maintenance work on the elevating device) (2) Since the notification by the output unit is prohibited, it is possible to suppress erroneous notification (for example, unnecessary notification during the maintenance work) regarding the abnormality of the elevating device during the maintenance work.

  In the remote monitoring system, the information on the characteristics of the maintenance worker may include at least one of a still image and a moving image.

  According to the remote monitoring system, by comparing the image from the imaging device with a still image or a moving image stored in the storage unit, it can be determined that the maintenance worker is staying around the elevating device, It is possible to more accurately determine whether the lifting device is under maintenance.

  In the remote monitoring system, the still image may include at least one of a still image of the maintenance worker and a still image of an object of the maintenance worker.

  According to the remote monitoring system, by comparing the image from the imaging device with a still image of the maintenance worker himself or a still image of an object possessed by the maintenance worker, whether or not the lifting device is under maintenance work Accurate judgment can be realized.

  In the remote monitoring system, the moving image may be a moving image related to an operation during the maintenance work.

  According to the remote monitoring system, it is possible to accurately determine whether or not the elevating device is under maintenance by comparing an image from the imaging device with a moving image related to an operation at the time of maintenance.

  In the remote monitoring system, the information related to the characteristics of the maintenance worker includes a still image and a moving image, and the processing unit transmits the information of the image received from the imaging device based on one of the still image and the moving image. It is determined whether or not the information related to the feature stored in the storage unit has information, and when it is determined that the information related to the image has information related to the feature, based on the other of the still image and the moving image, Then, it may be determined whether or not the information on the image received from the imaging device has the information on the feature stored in the storage unit.

  According to the remote monitoring system, when the image from the imaging device has information on the characteristics of the maintenance worker for both the still image and the moving image stored in the storage unit, Since it can be determined that the maintenance worker is staying, it is possible to more accurately determine whether the lifting device is under maintenance.

  In the remote monitoring system, after a lapse of a predetermined time after starting the normal operation, or after performing the normal operation a predetermined number of times without outputting the abnormal signal from the control microcomputer, the notification by the output unit is permitted. May be done.

  According to the remote monitoring system, during the elapse of a predetermined time or less than a predetermined number of times after starting the normal operation (for example, during a plurality of trial runs in a state where a maintenance worker who performs maintenance work is boarded). Even if an abnormality occurs in the elevating device, notification by the output unit can be prevented.

  As described above, according to the present invention, it is possible to provide a remote monitoring system for a lifting device capable of suppressing erroneous notification of an abnormality of the lifting device.

FIG. 1 is a block diagram of a remote monitoring system according to an embodiment of the present invention. FIG. 2 is a block diagram of a remote monitoring system according to a modification of the present invention.

  Hereinafter, a remote monitoring system for a lifting device according to the present invention will be described. The remote monitoring system is a system that remotely monitors the operation status of the lifting device. In this remote monitoring system, for example, when an abnormality such as a trouble such as a stoppage of operation of the elevating device occurs in the normal operation state, the monitoring terminal connected to the elevating device informs about the abnormality of the elevating device. By appropriately performing the notification in this way, the monitoring person monitoring the monitoring terminal can dispatch the maintenance worker to the site (the elevating device where the abnormality has occurred).

  On the other hand, during the maintenance work of the lifting / lowering device, the automatic driving and the manual operation are switched to operate the lifting / lowering device. During this manual operation, a maintenance worker may intentionally perform an operation with an abnormality occurring in the elevating device to check the operation. On the other hand, in the remote monitoring system for the lifting device according to the present invention, even if an abnormality occurs in the lifting device during the maintenance work, the monitoring terminal does not report the abnormality, and thus the false notification (for example, during the maintenance work). Unnecessary notification) can be prevented.

  The elevator device includes an elevator, an escalator, and the like. Hereinafter, a remote monitoring system for the elevator will be described.

  As shown in FIG. 1, the remote monitoring system includes an elevator 2 having a control microcomputer 20 capable of outputting an abnormal signal and a camera (imaging device) 210, a server (image recognition unit) 3 connected to the camera 210, A monitoring terminal (output unit) 4 is connected to the microcomputer 20 via the communication system R1 and is capable of notifying an abnormality based on an abnormality signal.

  The remote monitoring system 1 of the present embodiment includes a remote monitoring unit 5 provided in a communication system R1 (between the control microcomputer 20 and the monitoring terminal 4). 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, for example, and can communicate with the monitoring terminal 4 via the telephone line and the remote monitoring unit 5 in reverse. Communication system capable of communicating with the elevator 2.

  Although one monitoring terminal 4 is shown in FIG. 1, the remote monitoring system 1 according to the present embodiment includes a plurality of monitoring terminals 4. In addition, since each monitoring terminal 4 can switch the connection to a plurality of elevators 2 via the communication system R1 and connect to any elevator, the remote monitoring system 1 of the present embodiment includes a plurality of monitoring terminals. Equipped with an elevator.

  The elevator 2 has, in addition to the control microcomputer 20 and the camera 210, a car 21 connected to the control microcomputer 20 and moving up and down in the hoistway.

  The camera 210 is installed, for example, in the car 21. Specifically, the camera 210 is arranged on the ceiling of the car 21 and images the inside of the car 21 and the entrance and exit of the car 21 over time. It should be noted that the camera 210 can image the landing when the door of the car 21 is open.

  The camera 210 is connected to the server 3 via, for example, a LAN. Thereby, the camera 210 can output information of an image (a plurality of captured images) of the inside of the car 21 or the like to the server 3. In the car 21, for example, one monitoring camera is provided to monitor the entrance and exit of the car 21 and the car 21. In the remote monitoring system 1 of the present embodiment, this monitoring camera is used as the camera 210. A camera is used.

  When a trouble or the like occurs in the elevator 2, maintenance work may be performed on the elevator 2 by a maintenance worker. During the maintenance work of the elevator 2, for example, manual operation and automatic operation may be repeated. The maintenance work of the elevator 2 is performed after a predetermined time (for example, about 2 to 3 hours) has elapsed since the elevator 2 was set to the normal operation after the maintenance worker or the like confirmed that the trouble or the like was resolved, or The completed operation of the elevator 2 is completed a predetermined number of times (for example, about 5 to 10 times).

  Specifically, the maintenance work of the elevator 2 is completed by repeating the normal operation of the elevator 2 in the normal operation state a predetermined number of times after the maintenance worker confirms that the trouble has been resolved. Note that the normal operation is an automatic operation in a state where no abnormality occurs in the elevator 2. One normal operation is an operation from the start of the movement of the car 21 in the elevator 2 set to the normal operation to the stop of the movement of the car 21. Further, "the normal operation is continuously repeated a predetermined number of times" means that only the normal operation is continuously performed a predetermined number of times or more, and does not correspond to a case where a manual operation is included during the normal operation.

  Specifically, "the normal operation is continuously repeated a predetermined number of times" means that, in the elevator 2 that has been in the normal operation, the car 21 starts moving by pressing the call button at the landing, and then arrives at this landing. The normal operation until the car 21 moves to the destination floor and stops by pressing the destination button in the car 21 is continuously performed a predetermined number of times or more. It should be noted that a period during which the movement of the car 21 stops during one normal operation may be included.

  Note that normal operation is performed on the assumption that a user gets on the vehicle. During the maintenance work, the maintenance work is performed without assuming that the user gets in. Specifically, when a call is input to the elevator 2 during normal operation by using a landing button, the car 21 moves to the floor where the call is input. On the other hand, the elevator 2 during the maintenance work does not accept a call from the landing button.

  The car 21 is provided with various sensors capable of detecting the operation status of the elevator 2 and outputting the detection result as a signal relating to the operation status of the elevator 2. The sensor can output various signals corresponding to the operation status of the elevator 2.

  Further, the control microcomputer 20 always receives output of information on the operation status of the elevator 2 by a sensor (a sensor provided in the car 21). Further, when information is output from the sensor, the control microcomputer 20, based on the output information, for example, car position information, car door opening / closing information, car driving motor driving information, and Outputs an event code indicating a power failure or the like. The event code includes an abnormal signal (an event code indicating an abnormality of the elevator 2 such as a lock-in of a user in a car, a failure of a car door or a landing door, and a service life of a car light).

  When an abnormal signal is output from the control microcomputer 20, the remote monitoring unit 5 monitors information (for example, the machine number of the elevator 2) regarding these output source elevators and the content of the abnormal signal (for example, an event code). Output to the terminal 4 is possible.

  In the remote monitoring system 1 of the present embodiment, the remote monitoring unit 5 is connected to the server 3 via, for example, a LAN. Thereby, the remote monitoring unit 5 always receives the output of the prohibition signal and the permission signal from the server 3 described later. When the control microcomputer 20 outputs an abnormal signal and the server 3 outputs a permission signal, the remote monitoring unit 5 outputs information on the output source elevator (for example, the elevator number of the elevator 2) and an abnormal signal. (For example, an event code) is output to the monitoring terminal 4.

  Further, in the remote monitoring system 1 of the present embodiment, the remote monitoring unit 5 outputs a prohibition signal from the server 3 when an abnormal signal is output from the control microcomputer 20, and a predetermined time after starting normal operation. After the lapse of time, information on the output source elevator (for example, the machine number of the elevator 2) and the content of the abnormal signal (for example, an event code) are output to the monitoring terminal 4. Furthermore, in the remote monitoring system 1 according to the present embodiment, if a prohibition signal is output from the server 3 and a predetermined time has elapsed since the start of the normal operation, information on the output source elevator (for example, the elevator 2 The device number) and the content of the abnormal signal (for example, an event code) are not output to the monitoring terminal 4. The predetermined time is, for example, 2 to 3 hours.

  The monitoring terminal 4 of the present embodiment monitors, for example, a large number of elevators installed in a plurality of areas, and is installed in a monitoring center or the like, which is a building apart from the target elevator. A monitoring person (operator) is resident at the monitoring center of the present embodiment.

  To the monitoring terminal 4, information (for example, the machine number of the elevator 2) and an abnormal signal regarding the output source elevator are output from the control microcomputer 20 via the remote monitoring unit 5. The monitoring terminal 4 includes, for example, a display unit 40 capable of displaying information (for example, elevator number) of the output source elevator 2 and the content of an abnormal signal (event code) from the control microcomputer 20. The display unit 40 is, for example, a display.

  In the remote monitoring system 1 of the present embodiment, when an abnormal signal is output from the control microcomputer 20, the display unit 40 outputs information (for example, elevator number) of the output source elevator 2 and the content of the abnormal signal (event code or the like). ) Is displayed to notify the monitor of an abnormality related to the elevator 2. The observer can grasp the abnormality of the elevator 2 by checking this display.

  The server 3 determines whether or not the storage unit 30 storing the information on the characteristics of the maintenance worker and the information on the image received from the camera 210 has the information on the characteristics of the maintenance worker stored in the storage unit 30. And a processing unit 31 that performs the processing.

  In the remote monitoring system 1 of the present embodiment, the server 3 is installed at a site (in the elevator 2 (for example, any of a car, a tower, a machine room, and a management room). May be installed one by one for each elevator, or one may be installed for a plurality of elevators.

  The storage unit 30 stores, for example, a still image and a moving image as information on the characteristics of the maintenance worker.

  Specifically, the storage unit 30 stores both a still image of the maintenance worker himself and a still image of an object owned by the maintenance worker as information on the characteristics of the maintenance worker. As a still image of the maintenance worker, for example, a still image of the face of each maintenance worker or the like can be given. Still images of things that maintenance workers have are, for example, hats and jackets worn by maintenance workers, or letters and logos printed on tool cases and bags carried by maintenance workers. Still images and the like.

  In addition, the storage unit 30 stores information on operations during maintenance work as information on the characteristics of the maintenance worker. As information on the operation at the time of the maintenance work, for example, an operation that is always performed at the time of the maintenance work is cited. Such an operation includes, for example, an operation of opening the operation panel, an operation of manually opening the door of the car 21, and the like.

  When receiving the information on the image output from the camera 210, the processing unit 31 determines whether the information on the image received from the camera 210 has the information on the characteristics of the maintenance worker stored in the storage unit 30. A prohibition signal or a permission signal is output to the remote monitoring unit 5 according to the result of this determination. The processing unit 31 determines, for example, in two stages, whether or not the information of the image received from the camera 210 has the information on the characteristics of the maintenance worker stored in the storage unit 30.

  Specifically, when the processing unit 31 determines that the information of the image received from the camera 210 includes information on the characteristics of the maintenance worker based on the still image stored in the storage unit 30, Based on the moving image stored in the unit 30, it is determined that the information on the image received from the camera 210 has information on the characteristics of the maintenance worker. When the processing unit 31 determines that the information of the image received from the camera 210 includes information on the characteristics of the maintenance worker based on the still image and the moving image stored in the storage unit, the processing unit 31 outputs a prohibition signal to the remote monitoring unit. 5 is output.

  Further, based on the still image stored in the storage unit 30, the processing unit 31 determines that the information of the image received from the camera 210 does not include information on the characteristics of the maintenance worker, or The information of the image received from the camera 210 is determined based on the moving image stored in the storage unit 30 based on the moving image stored in the storage unit 30. When it is determined that the information does not have information on the feature, the permission signal is output to the remote monitoring unit 5.

  Note that the processing unit 31 determines whether or not the information of the image received from the camera 210 matches the information (still image or moving image) on the characteristics of the maintenance worker completely in addition to the information of the image received from the camera 210. If the information and the information (still image or moving image) on the characteristics of the maintenance worker match to some extent (for example, 80% or more), the information of the image received from the camera 210 is stored in the storage unit 30. It is determined that the maintenance worker has information on the characteristics of the maintenance worker.

  As described above, in the remote monitoring system 1 of the present embodiment, when the inhibition signal is output from the server 3 to the remote monitoring unit 5, even if the control microcomputer 20 outputs an abnormal signal, the remote monitoring unit 5 Since the abnormal signal is not output to the terminal 4, the notification by the monitoring terminal 4 is prohibited.

  According to the above remote monitoring system 1, when it is determined that the maintenance worker is staying around the elevator 2 based on the image from the camera 210 (it is determined that the maintenance work of the elevator 2 is being performed). Since the notification by the monitoring terminal 4 is prohibited, erroneous notification regarding the abnormality of the elevator 2 during the maintenance work can be suppressed.

  The erroneous notification mentioned here is, for example, unnecessary notification during maintenance work. Specifically, when the maintenance worker is staying around the elevator 2, there is no need to send the maintenance worker to the elevator 2, so that the notification is unnecessary. Also, when the maintenance worker causes an intentional abnormality in the elevator 2 during the maintenance work, the notification is not required.

  According to the remote monitoring system 1 of the present embodiment, the maintenance worker stays around the elevator 2 by comparing the image from the camera 210 with the still image or the moving image stored in the storage unit 30. Therefore, it can be accurately determined whether or not the elevator 2 is under maintenance work.

  Further, according to the remote monitoring system 1 of the present embodiment, the elevator 2 performs the maintenance work by comparing the image from the camera 210 with a still image of the maintenance worker himself or a still image of the maintenance worker. Accurate determination of whether or not it is inside can be realized.

  Further, according to the remote monitoring system 1 of the present embodiment, by comparing the image from the camera 210 and the moving image related to the operation during the maintenance work, it is possible to accurately determine whether the elevator 2 is under the maintenance work. Can be realized.

  According to the remote monitoring system 1 of the present embodiment, when the image from the camera 210 has information on the characteristics of the maintenance worker for both the still image and the moving image stored in the storage unit 30, Since it can be determined that the maintenance worker is staying around the elevator 2, it can be more accurately determined whether the elevator 2 is under maintenance.

  In addition, according to the remote monitoring system 1 of the present embodiment, during a predetermined period of time has elapsed since the start of the normal operation (for example, during a plurality of trial runs in a state where the maintenance worker performing the maintenance work is on the car 21). Even if an abnormality occurs in the elevator 2), the monitoring terminal 4 can prevent the notification.

  Note that the remote monitoring system 1 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 one embodiment can be added to the configuration of another embodiment, and a part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Further, a part of the configuration of an embodiment can be deleted.

  For example, the storage unit 30 stores both a still image and a moving image as information on the characteristics of the maintenance worker, but may store one of both the still image and the moving image. In this case, the processing unit 31 determines whether the image from the camera 210 has information on the characteristics of the maintenance worker based on the still image or the moving image stored in the storage unit 30, and according to the determination result, The prohibition signal and the permission signal are output to the remote monitoring unit 5. Thereby, when it is determined that the maintenance worker is staying in the vicinity of the elevator 2, it is possible to prevent the monitoring terminal 4 from notifying, and thus it is possible to suppress erroneous notification regarding the abnormality of the elevator 2 during the maintenance work.

  Further, based on the still image stored in the storage unit 30, the processing unit 31 determines that the information of the image received from the camera 210 has information on the characteristics of the maintenance worker, and then stores the information in the storage unit 30. Based on the stored moving image, it is determined that the information of the image received from the camera 210 has information on the characteristics of the maintenance worker. However, the determination based on the still image (one of the still image and the moving image) is performed. After, the determination based on the moving image (the other of the still image and the moving image) may be performed. Also in this case, the processing unit 31 performs the determination in two steps using the still image and the moving image, so that it is possible to more accurately determine whether the maintenance worker is staying around the elevator 2. .

  When a predetermined time has elapsed since the start of the normal operation, the remote monitoring unit 5 has permitted the notification by the monitoring terminal 4 when the control microcomputer 20 outputs the abnormal signal. The notification by the monitoring terminal 4 in the case where an abnormal signal is output from the control microcomputer 20 when the number of times has been performed may be permitted. Specifically, the remote monitoring unit 5 outputs the abnormal signal when the information about the abnormality of the elevator 2 is output from the sensor after performing the normal operation continuously for a predetermined number of times without outputting the abnormal signal. Accordingly, the notification by the monitoring terminal 4 is permitted. Even in this case, even if an abnormality occurs in the elevator 2 that is being tested a plurality of times while a maintenance worker performing the maintenance work is on board, it is possible to prevent the monitoring terminal 4 from notifying. The predetermined number of times is, for example, 5 to 10 times.

  Further, in the remote monitoring system 1 of the above embodiment, when the information about the abnormality of the elevator 2 is output from the sensor, the remote monitoring unit 5 sends the information to the monitoring terminal 4 in response to the prohibition signal or the permission signal from the server 3. Although the notification of the monitoring terminal 4 has been permitted or prohibited by outputting the abnormal signal or preventing the output of the abnormal signal to the monitoring terminal 4, the control microcomputer 20 or the monitoring terminal 4 itself may permit or prohibit the notification of the monitoring terminal 4. In this case, the server 3 may output a prohibition signal or a permission signal to the control microcomputer 20 or the monitoring terminal 4.

  Specifically, the control microcomputer 20 outputs an abnormal signal when the server 3 outputs a prohibition signal when information on an abnormality of the elevator 2 is output from the sensor. The control microcomputer 20 outputs an abnormal signal when the permission signal is output from the server 3 when the information regarding the abnormality of the elevator 2 is output from the sensor. As described above, the control microcomputer 20 outputs the abnormal signal in response to the prohibition signal or the permission signal from the server 3, so that the notification by the monitoring terminal 4 can be prohibited or permitted.

  Further, specifically, when the prohibition signal is output from the server 3 when the control microcomputer 20 outputs the abnormal signal, the monitoring terminal 4 does not display the content of the abnormal signal on the display unit 40 (notification). do not do). The monitoring terminal 4 displays (notifies) the content of the abnormal signal on the display unit 40 when the permission signal is output from the server 3 when the control microcomputer 20 outputs the abnormal signal. As described above, the monitoring terminal 4 performs the notification according to the prohibition signal or the permission signal from the server 3, so that the notification by the monitoring terminal 4 itself can be prohibited or permitted.

  The elevator 2 may include, in addition to the control microcomputer 20 and the car 21, a maintenance work switch for switching between automatic operation and manual operation, and a maintenance switch for permitting or prohibiting notification by the monitoring terminal 4.

  The maintenance work switch includes, for example, an operation switch and an automatic operation switch. The operation switch is a switch that switches between an automatic operation and a stopped state of the elevator. Hereinafter, an operation of switching the operation switch from ON to OFF is referred to as an OFF operation, and an operation of switching the operation switch from OFF to ON is referred to as an ON operation. The same applies to the manual operation switch and the maintenance switch.

  The operation switch is a switch for automatically operating the elevator 2 when it is ON and stopping the elevator 2 when it is OFF. Therefore, when the operation switch is turned on, the elevator 2 is switched to the normal operation, and when the operation switch is turned off, the elevator 2 is switched during the maintenance work.

  The manual operation switch is a switch that enables the elevator 2 to be manually operated when it is ON, and automatically operates the elevator 2 when it is OFF. Beside the manual operation switch, for example, an UP button and a DOWN button are provided. By pressing these buttons when the manual operation switch is ON, the car 21 can be moved up and down at a lower speed than in automatic operation. Therefore, such manual operation is performed, for example, during maintenance work by a technician. Is Therefore, the manual operation switch switches the elevator 2 during maintenance work by being turned ON, and switches the elevator 2 to normal operation by being turned OFF.

  The maintenance switch is a switch that switches between permission and prohibition of the notification of the monitoring terminal 4. The maintenance switch prohibits the notification based on the abnormal signal from the control microcomputer 20 when the maintenance switch is ON, thereby prohibiting the notification of the monitoring terminal 4 and permits the alarm based on the abnormal signal from the control microcomputer 20 when the maintenance switch is OFF. By doing so, the notification of the monitoring terminal 4 is permitted. Here, the alarm is output of information from the control microcomputer 20 to the monitoring terminal 4.

  A plurality of cameras 210 may be provided in the car 21. Further, instead of using a surveillance camera as camera 210, another camera other than the surveillance camera may be used. Further, although the camera 210 is arranged on the ceiling in the car 21, it may be arranged on a wall or the like in the car 21 or may be arranged on a landing or the like. Further, the camera 210 may be arranged in both the car 21 and the landing.

  The server 3 is connected to the camera 210 and the remote monitoring unit 5 via a LAN, but the LAN may be a wired LAN or a wireless LAN. The server 3 may be connected to the camera 210 and the remote monitoring unit 5 via the Internet instead of the LAN. The server 3 has been installed at the site, but may be installed at a location remote from the site.

  The communication system R1 includes a telephone line, but may include the Internet instead of the telephone line as shown in FIG. Further, the communication system R1 may not include the remote monitoring unit 5. In this case, if the server 3 is connected to the remote monitoring unit 5 via the Internet instead of the LAN and the camera 210 is connected to the server 3 via the Internet instead of the LAN, the communication system R1 and the server A communication system from the camera 3 to the remote monitoring unit 5 and a communication system from the camera 210 to the server 3 can be shared in part (Internet).

  Although the remote monitoring system 1 of the above embodiment includes a plurality of elevators, the remote monitoring system 1 may include a single elevator.

  Further, the remote monitoring system 1 of the above embodiment is directed to an elevator, but may be directed to an escalator. In this case, the camera 210 may be installed so as to capture at least a part of the escalator. Further, in this case, the storage unit 30 only needs to store, for example, information regarding an operation at the time of installation of a safety fence, operation of an operation panel, or the like, as information regarding an operation at the time of maintenance work.
