However, it is not necessary to acquire information and images related to this abnormality. The monitoring terminal 4 may, for example, acquire an image in response to an instruction from the supervisor when the supervisor who has checked the information about the abnormality on the display unit 40 determines that it is necessary, or may acquire an image from the information about the abnormality. is stored in the control microcomputer 20, the information and images related to the abnormality 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 by one in all stories, and open and close the car door 210 each time the car 21 stops", It is not necessary to check whether there is a hall call until the opening and closing of the car doors 210 on all floors 30 provided in the building 3 is completed.

In the inspection mode, the indicator 300 is also activated when the control microcomputer 20 outputs a signal indicating that the car 21 is stopped to the floor 30 and immediately after that a signal indicating that the car door 210 is to be opened is output. (For example, the message "A basket has arrived.") was displayed, but instead of this message, a message about opening and closing the door (for example, "The door will open, please be careful. .” message) may be displayed.

The notification device provided on the floor 30 may be at least one of an indicator 300, a speaker, a hall lantern, and the like. The speaker notifies at least one of elevating/lowering of the car 21, arrival of the car 21, and opening/closing of the door, for example. When the notification device includes a speaker, the information to be notified is voice information such as voice announcement, gong sound, chime sound, and the like. The hall lantern announces the arrival of the car 21. Also, the indicator 300 may be arranged above the car jump button 310 or the like. No matter what the notification device is configured, in the inspection mode, by notifying when the car door 210 that stops at the floor 30 on which it is installed opens, when remotely igniting the elevator 2, A person staying near the door on the floor 30 predicts the arrival of the car 21 and the subsequent opening of the door (for example, the floor door 320 that opens and closes in conjunction with the car door 210), and opens and closes the car door 210 and the floor door 320. A commissioning can be carried out with

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

The control microcomputer 20 stores information about an abnormality in itself during the inspection mode, but when it receives an input indicating that an abnormality has occurred in the elevator 2 from a sensor provided in the car 21, it controls the information about the abnormality. The data may be output to a monitor terminal 4 different from the microcomputer 20, a storage server, or the like. In this case, instead of the control microcomputer 20 storing the information on the abnormality, the monitoring terminal 4 or the like may store the information on the abnormality output from the control microcomputer 20 . Also, in this case, the monitoring terminal 4 may extract information about an abnormality during the inspection mode stored therein.

Similarly, the camera 211 may also output images captured during the inspection mode to the monitoring terminal 4, a storage server, or the like. 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 . Also, in this case, the monitoring terminal 4 may acquire the "image captured at the timing when the information about the abnormality in the inspection mode was stored" stored therein.

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

In the remote monitoring system 1 of the above-described embodiment, the door opening/closing inspection is performed by switching to the inspection mode via the input unit 41 and performing "door inspection" by the surveillance staff. The date and time to switch to the mode and the contents of the inspection ("door inspection" etc.) may be registered in a schedule so that the mode is automatically switched to the inspection mode and the door opening/closing inspection is performed at the scheduled date and time.

In addition, the monitor terminal 4 instructs the control microcomputer 20 to switch to the normal operation mode when the inspection of door opening/closing is completed and the observer performs an operation to switch to the normal operation mode. It may be preset to switch to the normal operation mode immediately.

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

Although the remote monitoring system 1 of the above embodiment has a plurality of remote monitoring units 5, it may have a single remote monitoring unit 5. FIG. In this case, the remote monitoring system 1 may have one elevator.

Communication system R1 may include the Internet instead of a telephone line. For example, as shown in FIG. 4, the communication system R1 is capable of communicating with the monitoring terminal 4 via the remote monitoring unit 5 and the Internet in order from the elevator 2, 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 .

Instead of the monitoring terminal 4, a terminal different from the monitoring terminal 4 (for example, as shown in FIG. 5, a mobile terminal (terminal) 6 connectable to the control microcomputer 20 via the Internet) performs inspection mode setting and control microcomputer A hierarchy 30 instruction to 20 to stop car 21 may be provided. The mobile terminal 6 is, for example, a terminal such as a PDA (Personal Digital Assistant), a smart phone, a notebook computer, etc., and is possessed by a technician capable of responding to an abnormality in the elevator 2 .

The mobile terminal 6 receives information output from the monitoring terminal 4 (e.g., information related to secondment from the monitoring terminal 4 or request for remote response), an event code indicating an abnormality, and the camera 211 at the timing at which the event code was stored. It has a display unit 60 capable of displaying captured images 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, input keys, a keyboard, or the like. If the mobile terminal 6 has a touch panel display, this display serves as both the display section 60 and the input section 61 .

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