5 is a diagram showing an example of the camera unit 33. As shown in FIG. FIG. 6 is a diagram for explaining the functions of the camera unit 33. As shown in FIG. The camera unit 33 includes a camera 41 , a cover 42 , a magnet 43 , a power line 44 , an antenna 45 , and a control device 46 .

The camera 41 is capable of taking pictures with at least visible light. A cover 42 is fixed to the camera 41 . A magnet 43 is fixed to the cover 42 . For example, the magnet 43 is adhesively fixed to the cover 42 so as to be disposed between the camera 41 and the cover 42 .

2 shows an example in which the camera 41 is fixed to the surface 24c of the lower member 24b. The face 24c is a downward face formed on the lower member 24b. The lower member 24b is a member that can contact the shock absorber 3b from above when the car 1 falls due to the break of the main rope 4. The shock absorber 3b is provided in the pit 3a as one of the safety devices. The shock absorber 3b is disposed below the car 1, more specifically, below the lower member 24b. The camera 41 is fixed to the surface 24c so as not to come into contact with the shock absorber 3b.

In the example shown in this embodiment, the camera 41 is suction-fixed to the lower member 24b by the magnet 43. When the camera 41 is fixed to the surface 24c, a cover 42 is disposed so as to cover the upper side of the camera 41. Further, when the camera 41 is fixed to the surface 24c, the direction of the camera 41 is set so that the lower side of the car 1 is photographed. The camera unit 33 may be provided with a mechanism for adjusting the shooting direction of the camera 41 .

The other end of the fall prevention wire 34 is fixed to the camera 41 or the cover 42 . The fall prevention wire 34 may be provided in the imaging unit 19 as needed. When the camera 41 is fixed by the magnet 43, it is preferable that the imaging unit 19 is equipped with a fall prevention wire 34.

Next, an example of using an image captured by the camera 41 will be described. As described above, the operation of the video unit 19 is the same as that of the video unit 18. For this reason, in this embodiment and other embodiments, detailed descriptions of examples using images captured by the camera included in the camera unit of the imaging unit 18 are omitted.

7 is a flowchart showing an example of the operation of the imaging unit 19. As an example, the operating panel 25 of the car 1 is equipped with a switch 25a for supplying power to the socket 17 . The switch 25a may be provided in the control device 7 or the monitoring device 8. When a specific operation is performed on the switch 25a, power is supplied to the socket 17. For example, the switch 25a can be turned on or off manually. When the switch 25a is off, power is not supplied to the socket 17. When power is not supplied to the socket 17, no light is emitted from the lamp unit 31. If power is not supplied to the socket 17, no photographing is performed by the camera 41.

Switch 25a is basically off. The maintenance worker turns on the switch 25a in the car 1 when inspecting the elevator. When the switch 25a is turned on, power is supplied to the socket 17, and power is supplied from the socket 17 to the imaging unit 19 (S101). That is, power is supplied to the lamp unit 31 through the socket 17 and the adapter 30 . As a result, visible light is emitted from the lamp unit 31 (S102). In addition, power is supplied to the camera unit 33 through the socket 17 and the adapter 30 . Thereby, photographing by the camera 41 is started (S103). For example, an image of the pit 3a is photographed by the camera 41 .

The communication unit 61 has a function of transmitting video data. The image data is data representing an image photographed by the camera 41 . After the switch 25a is turned on, i.e., power is supplied to the camera unit 33, the communication unit 61 becomes capable of transmitting video data. For example, when power is supplied to the camera unit 33, the communication unit 61 transmits radio waves for communication from the antenna 45. In the control device 46, it is determined whether a connection with other devices has been established, that is, whether or not communication with the other devices has been established (S104).

The maintenance worker performs a specific authentication operation on the portable terminal 13 to wirelessly connect the portable terminal 13 to the camera unit 33 . 8 is a diagram showing an example of the portable terminal 13. As shown in FIG. 9 is a flowchart showing an operation example of the mobile terminal 13. As shown in FIG. The mobile terminal 13 includes an input device 70 and a display device 71 . The maintenance worker inputs necessary information from the input device 70. The input device 70 and the display device 71 may be a touch panel type integrated device. The input device 70 may be a keyboard or a mouse. The mobile terminal 13 further includes a storage unit 72, a display control unit 73, and a communication unit 74. The display control unit 73 controls the display unit 71 .

For example, when the communication unit 74 receives a radio wave from the antenna 45, the display control unit 73 displays information for specifying the camera unit 33 on the display unit 71. The maintenance worker designates the corresponding information using the input device 70 and inputs the password. The communication unit 74 transmits the entered password to the camera unit 33. In the mobile terminal 13, it is determined whether or not it is connected to the camera unit 33 (S201).

When the communication unit 61 receives the correct password from the portable terminal 13, the camera unit 33 and the portable terminal 13 are connected wirelessly. By this, it is determined as Yes in S104. Moreover, it is determined as Yes in S201. If it is determined as Yes in S104, the communication unit 61 transmits data indicating an image captured by the camera 41, that is, image data by the camera 41 to the portable terminal 13 (S105).

If it is judged Yes in S201, the mobile terminal 13 determines whether or not video data has been received from the camera unit 33 (S202). The video data transmitted by the communication unit 61 in S105 is received by the communication unit 74 (Yes in S202). The display control unit 73 displays the video taken by the camera 41 on the display unit 71 based on the video data received by the communication unit 74 from the camera unit 33 (S203). Thereby, the maintenance worker can view the real-time video of the pit 3a while getting into the car 1.

If communication between the mobile terminal 13 and the camera unit 33 is not disconnected (No in S204), the processing of the mobile terminal 13 returns to S202. When communication between the portable terminal 13 and the camera unit 33 is disconnected (Yes in S204), the portable terminal 13 ends the process.

In the imaging unit 19, if power is being supplied, the processing shown in S102 to S105 is repeatedly performed. When the maintenance worker turns off the switch 25a, power to the imaging unit 19 is cut off (Yes in S106). If Yes is determined in S106, the imaging unit 19 ends the processing.

In addition, in the imaging unit 19, photographing by the camera 41 may be started after determining Yes in S104. For example, photographing by the camera 41 may be started by receiving a specific signal from the portable terminal 13 after communication between the camera unit 33 and the portable terminal 13 is established. At this time, the image quality of the camera 41 may be set according to the communication conditions between the camera unit 33 and the portable terminal 13 .

In the example shown in this embodiment, power supply to the imaging unit 19 is performed through the socket 17. For this reason, it is possible to supply power to the imaging unit 19 using existing facilities or designs. If it is the example shown in this embodiment, it becomes possible to ensure the power supply for the imaging unit 19, especially the power supply for the camera 41 easily.

Other functions employable by this elevator system will be described below. If possible, the present elevator system may be employed by combining a plurality of functions shown below. Elevator systems disclosed in other embodiments can also adopt functions described later.

First, functions employable by the imaging unit 19 will be described. For example, if brightness necessary for photographing can be secured without the lamp unit 31, the imaging unit 19 does not need to include the lamp unit 31. Moreover, the function of the lamp unit 31 may be equipped with the camera unit 33.

As another example, the body 35 of the adapter 30 may be provided with a plurality of sockets 38 for light bulbs. In this case, the body 35 does not need to include the outlet 37. For example, the lamp unit 31 is fixed to one socket 38. A camera unit 33 is fixed to another socket 38 . If a clasp detachable from the socket 38 is included in the power supply line 44 , the camera unit 33 can be fixed to the socket 38 . In order to connect the plug 44a to the socket 38, another adapter having a clasp detachable from the socket 38 and a receptacle into which the plug 44a can be inserted may further be used.

As another example, the camera unit 33 may further include a communication line for communicating with other devices. A maintenance worker may connect a maintenance equipment to this communication line to update a program or the like. When the maintenance worker views the video of the pit 3a on the mobile terminal 13, this communication line does not have to be used. In such a case, it is preferable to attach a dustproof cap to the connector provided at the tip of the communication line.

10 is a diagram showing another example of the camera unit 33. As shown in FIG. The camera unit 33 may further include a microphone 47, a speaker 48, an accelerometer 49, a gyro sensor 50, a barometer 51, a thermometer 52, and a hygrometer 53. The microphone 47, the speaker 48, the accelerometer 49, the gyro sensor 50, the barometer 51, the thermometer 52, and the hygrometer 53 are camera units (one or more of these as needed) 33) may be provided.

A microphone 47 detects sound. When the camera unit 33 is provided with the microphone 47, the communication unit 61 may transmit the sound data detected by the microphone 47 to the portable terminal 13 together with the video data.

The speaker 48 is controlled by a sound controller 62 provided in the control device 46.

The accelerometer 49 detects the acceleration of the camera unit 33 . When the camera unit 33 includes the accelerometer 49, the communication unit 61 may transmit acceleration data detected by the accelerometer 49 to the portable terminal 13 together with video data.

The gyro sensor 50 detects the angular velocity of the camera unit 33 . When the camera unit 33 includes the gyro sensor 50, the communication unit 61 may transmit angular velocity data detected by the gyro sensor 50 to the portable terminal 13 together with video data. Based on the acceleration data or the angular velocity data received from the portable terminal 13, the maintenance worker can confirm whether there is no problem in riding comfort.

The barometer 51 detects the air pressure of the place where the barometer 51 is placed. When the camera unit 33 is provided with the barometer 51, the communication unit 61 may transmit air pressure data detected by the barometer 51 to the portable terminal 13 together with video data. If a barometer (not shown) is also provided in the portable terminal 13, the barometric pressure detected by the barometer 51 based on the position of the car 1 and the barometric pressure detected by the barometer provided in the portable terminal 13 Using the difference in atmospheric pressure, the position where the maintenance source is located can be specified more accurately.

The thermometer 52 detects the temperature of the place where the thermometer 52 is placed. When the camera unit 33 is provided with the thermometer 52, the communication unit 61 may transmit temperature data detected by the thermometer 52 to the portable terminal 13 together with video data. The hygrometer 53 detects the humidity of the place where the hygrometer 53 is placed. When the camera unit 33 includes the hygrometer 53, the communication unit 61 may transmit humidity data detected by the hygrometer 53 to the portable terminal 13 together with video data. By using the temperature data and humidity data received by the mobile terminal 13, the lifetime of the substrate provided in the control device 7 or the like can be predicted.

In the example described above, power supply to the imaging unit 19 is performed by manual operation of the switch 25a. As another example, power supply to the imaging unit 19 may be realized by the functions of the control device 7 and the monitoring device 8 . Hereinafter, with reference also to FIGS. 11 to 16, a specific example in which the control device 7 and the monitoring device 8 realizes the function of supplying power to the imaging unit 19 will be described.

11 is a diagram showing an example of the control device 7 and the monitoring device 8 . The control device 7 includes a storage unit 80, a power supply unit 81, and an operation control unit 82. The power supply unit 81 controls power supply to the socket 17 .

The driving control unit 82 performs driving control according to the set driving mode. The operation mode includes, for example, an automatic mode, a maintenance mode, a diagnosis mode, a control mode, and a recovery mode. In the automatic mode, automatic driving is performed. Automatic operation is operation in which the car 1 sequentially responds to a registered call. In the maintenance mode, it is possible to move the car 1 by manual operation. In the diagnostic mode, diagnostic operation for determining the presence or absence of an abnormality is performed. For example, diagnostic operation is performed periodically. In the control mode, for example, earthquake control operation is performed. Earthquake control operations are performed immediately after an earthquake occurs. In the recovery mode, recovery operation for determining whether or not the elevator is being restored is performed. The recovery operation is performed after the earthquake control operation is performed.

The monitoring device 8 includes a storage unit 90, a condition determination unit 91, and a communication unit 92.

12 is a diagram showing an example of the external device 11 . The external device 11 includes an input device 100 and a display device 101 . A supervisor of the monitoring center 10 inputs necessary information from the input device 100 . The input device 100 and the display device 101 may be integrated devices of a touch panel type. The input device 100 may be a keyboard or a mouse. The external device 11 further includes a storage unit 102, a display control unit 103, and a communication unit 104. The display control unit 103 controls the display device 101 .

13 is a flowchart showing an example of the operation of the control device 7. If the interior of the hoistway 3 is illuminated during automatic driving, users may feel the light suspiciously. For this reason, the power supply unit 81 basically blocks power to the socket 17 (S301). As described above, when power is not supplied to the socket 17, no light is emitted from the lamp unit 31. If power is not supplied to the socket 17, no photographing is performed by the camera 41. In the control device 7, it is determined whether or not the first request signal for requesting photographing by the camera 41 has been received (S302). If it is determined as No in S302, the power supply unit 81 continues cutting off power to the socket 17.

14 is a flowchart showing an example of the operation of the monitoring device 8. The condition determination unit 91 determines whether or not shooting conditions are satisfied (S401). Shooting conditions are set in advance. As a shooting condition, a specific time period may be set. In this case, if the current time is included in the above time zone, it is determined as Yes in S401.

As another example, when the communication unit 92 receives a specific signal from the external device 11, the photographing condition may be established. 15 is a flowchart showing an example of the operation of the external device 11. As an example, a supervisor of the monitoring center 10 inputs specific information from the input device 100 when wanting to view an image captured by the camera 41 on the display device 101 . When the corresponding information is input from the input device 100, the communication unit 104 transmits a second request signal for requesting video data by the camera 41 to the monitoring device 8 via the network 9 ( S501).

When the communication unit 92 receives the second request signal from the external device 11, the photographing condition is established (Yes in S401). If it is determined as Yes in S401, the communication unit 92 transmits a first request signal to the control device 7 (S402).

When the control device 7 receives the first request signal transmitted by the communication unit 92 in S402, it is determined as Yes in S302. If yes is determined in S302, the power supply unit 81 supplies power to the socket 17 (S303).

In the imaging unit 19, the operation shown in FIG. 7 is performed. That is, power is supplied from the socket 17 to the imaging unit 19 by the processing in S303 (S101). As a result, visible light is emitted from the lamp unit 31 (S102). Moreover, photographing by the camera 41 is started (S103).

Also, when power is supplied to the camera unit 33, the communication unit 61 transmits radio waves for communication from the antenna 45. If the communication unit 92 receives radio waves from the antenna 45 via the access point 12 after the communication unit 92 transmits the first request signal in S402, the monitoring device 8 and the monitoring device 8 go through specific authentication processing. The camera unit 33 is connected (Yes in S403). By this, it is determined as Yes also in S104. If it is determined as Yes in S104, the communication unit 61 transmits the video data by the camera 41 to the monitoring device 8 via the access point 12 (S105).

In the monitoring device 8, if it is determined as Yes in S403, it is determined whether or not video data has been received from the camera unit 33 (S404). The video data transmitted by the communication unit 61 in S105 is received by the communication unit 92 in the monitoring device 8 (Yes in S404). When the shooting condition is established in S401 by the monitoring device 8 receiving the second request signal, the communication unit 92 transmits the video data received from the communication unit 61 to the external device 11 in S404 (S405). .

In the external device 11, when the communication unit 104 transmits the second request signal in S501, it is determined whether video data has been received from the monitoring device 8 (S502). The video data transmitted by the communication unit 92 in S405 is received by the communication unit 104 in the external device 11 (Yes in S502). The display control unit 103 displays the video captured by the camera 41 on the display unit 101 based on the video data received by the communication unit 104 from the monitoring device 8 (S503). In this way, the supervisor can view the real-time video of the pit 3a in the monitoring center 10 .

Further, in the monitoring device 8, after the shooting conditions are met in S401, it is determined whether or not the ending conditions for ending the shooting have been met (S406). End conditions are set in advance. When a specific time zone is set as a photographing condition, the end condition is met if the current time is out of this time zone. As another example, the end condition may be satisfied when it is determined as No in S403 for a certain period of time. The termination condition may be established when a specific signal is received from the external device 11. If it is determined as Yes in S406, the communication unit 92 transmits a third request signal for requesting termination of photographing by the camera 41 to the control device 7 (S407).

In the control device 7, after determining Yes in S302, it is determined whether or not the third request signal has been received from the monitoring device 8 (S304). If it is determined as No in S304, the power supply unit 81 continues to supply power to the socket 17. When the control device 7 receives the third request signal transmitted by the communication unit 92 in S407, it is determined to be Yes in S304. If yes is determined in S304, the power supply unit 81 cuts off power to the socket 17 (S301).

Next, an example in which a supervisor of the monitoring center 10 views a past image captured by the camera 41 will be described.

In the control device 7, the operation shown in FIG. 13 is performed. As described above, if the interior of the hoistway 3 is illuminated during automatic driving, the user may feel the light suspiciously. For this reason, the power supply unit 81 basically blocks power to the socket 17 (S301). For example, the power supply unit 81 cuts off power to the socket 17 while autonomous driving is in progress. In the control device 7, it is determined whether or not the first request signal has been received (S302).

16 is a flowchart showing an example of the operation of the monitoring device 8. While the driving control unit 82 is performing automatic driving, the condition determination unit 91 determines whether or not the diagnosis condition is met (S601). Diagnosis conditions are set in advance. As an example, when a specific time on a specific day comes, the diagnosis condition is established. If the condition determination unit 91 determines that the diagnosis condition is satisfied (Yes in S601), the communication unit 92 transmits a first mode signal for setting the driving mode to the diagnosis mode to the controller 7 (S602). ).

When receiving the first mode signal from the monitoring device 8, the control device 7 starts diagnostic operation. That is, the driving control unit 82 performs diagnostic driving when the diagnostic conditions are satisfied. In the diagnostic operation, diagnostic data necessary for determining the presence or absence of an abnormality is acquired. The control device 7 transmits diagnostic data obtained in the diagnostic operation to the monitoring device 8 . The diagnostic data received by the communication unit 92 from the control device 7 are stored in the storage unit 90 in the monitoring device 8 .

In addition, the first mode signal transmitted by the communication unit 92 in S602 includes the first request signal. For this reason, when the control apparatus 7 receives the 1st mode signal transmitted by the communication part 92 in S602, it determines with Yes in S302. If yes is determined in S302, the power supply unit 81 supplies power to the socket 17 (S303).

In the imaging unit 19, the operation shown in FIG. 7 is performed. That is, power is supplied from the socket 17 to the imaging unit 19 by the processing in S303 (S101). As a result, visible light is emitted from the lamp unit 31 (S102), and photographing by the camera 41 is started (S103).

The processing shown in S603 and S604 in Fig. 16 is the same as the processing shown in S403 and S404 in Fig. 14 . That is, if the communication unit 92 receives radio waves from the antenna 45 via the access point 12 after the communication unit 92 transmits the first mode signal in S602, the monitoring device 8 goes through a specific authentication process. ) and the camera unit 33 are connected (Yes in S603). By this, it is determined as Yes also in S104. If it is determined as Yes in S104, the communication unit 61 transmits the video data by the camera 41 to the monitoring device 8 via the access point 12 (S105).

In the monitoring device 8, if it is determined as Yes in S603, it is determined whether or not video data has been received from the camera unit 33 (S604). The video data transmitted by the communication unit 61 in S105 is received by the communication unit 92 in the monitoring device 8 (Yes in S604). When the first mode signal (first request signal) is transmitted in S602 as a result of the diagnosis condition being established, the video data received by the communication unit 92 is stored in the storage unit 90 (S605). In S605, the video data received by the communication unit 92 is stored in the storage unit 90 as diagnostic data acquired in the diagnostic operation.

When the diagnostic operation by the driving controller 82 is finished (Yes in S606), the communication unit 92 transmits a second mode signal for setting the driving mode to the automatic mode to the controller 7 (S607). In the control device 7, upon receiving the second mode signal from the monitoring device 8, the operation control unit 82 resumes the automatic driving.

In addition, the third request signal is included in the second mode signal transmitted by the communication unit 92 in S607.

For this reason, when the control device 7 receives the second mode signal transmitted by the communication unit 92 in S607, it is determined as Yes in S304. If yes is determined in S304, the power supply unit 81 cuts off power to the socket 17 (S301). Also, if it is determined as Yes in S304, it is determined as Yes in S106. In this example, image data by the camera 41 can be included in the diagnosis data.

17 is a flowchart showing another operation example of the monitoring device 8. FIG. 17 shows an example of an operation performed separately from the operation shown in FIG. 16 .

In the monitoring device 8, it is determined whether or not a fourth request signal for requesting diagnostic data has been received (S701). As an example, a supervisor of the monitoring center 10 inputs specific information from the input device 100 when wanting to acquire diagnostic data. When corresponding information is input from the input device 100, the communication unit 104 transmits a fourth request signal to the monitoring device 8 through the network 9. As another example, the communication unit 104 may periodically transmit the fourth request signal to the monitoring device 8.

When the monitoring device 8 receives the fourth request signal from the external device 11, it is determined as Yes in S701. If it is judged Yes in S701, the communication unit 92 transmits the diagnostic data stored in the storage unit 90 to the external device 11 (S702). The diagnostic data transmitted by the communication unit 92 in S702 is received by the communication unit 104 in the external device 11 .

The diagnostic data received by the communication unit 104 from the monitoring device 8 includes video data obtained by the camera 41 . Based on the video data received by the communication unit 104 from the monitoring device 8, the display control unit 103 displays the video captured by the camera 41 on the display unit 101. In this way, the supervisor can view past images acquired in the diagnosis operation at the monitoring center 10 .

Next, an example of realizing the above elevator system by remodeling an existing elevator will be described. 18 is a flowchart illustrating an example of a method for numbering elevators. In the elevator before renovation, a light bulb for illuminating the inside of the hoistway 3 is provided in the car 1 via a socket 17. The maintenance worker first removes the existing light bulb attached to the socket 17 from the socket 17 (S801).

Next, the adapter 30 is attached to the socket 17 from which the existing light bulb was removed (S802). As described above, the adapter 30 is provided with a clasp 36 . By inserting the clasp 36 into the socket 17, the adapter 30 can be fixed to the socket 17.

Next, the camera unit 33 is supported on the car 1 (S803), and the camera unit 33 is connected to the adapter 30 so that power is supplied to the camera unit 33 through the socket 17. (S804). In the example shown in this embodiment, the camera unit 33 is equipped with the magnet 43. By attracting the magnet 43 to the surface 24c, the camera unit 33 is fixed to the lower member 24b of the car 1. Also, the plug 44a of the power supply line 44 is inserted into the outlet 37 of the adapter 30. With this, the camera 41 is electrically connected to the socket 17 via the power line 44 and the adapter 30. That is, power supply to the camera unit 33 is performed through the socket 17 and the adapter 30 .

Further, immediately after S803 or S804, a step of connecting the car 1 and the camera 41 or the cover 42 with the fall prevention wire 34 may be provided.

Next, the lamp unit 31 is mounted on the adapter 30 (S805). In the example shown in this embodiment, the lamp unit 31 is provided with the clasp 40. By inserting the clasp 40 into the socket 38 of the adapter 30, the lamp unit 31 can be fixed to the socket 38. Power supply to the lamp unit 31 is performed through a socket 17 and an adapter 30 . Next, the cover 32 is attached to the adapter 30, and the lamp unit 31 is covered with the cover 32 (S806).

In addition, the procedures shown in S805 and S806 may be performed before the procedures shown in S803 and S804.

Embodiment 2.

In Embodiment 1, an example in which power is supplied to the imaging unit 19 when photographing by the camera 41 has been described has been described. In this embodiment, an example in which power is always supplied to the imaging unit 19 will be described.

Also in the present embodiment, the video unit 19 disposed below the car 1 will be described in detail. In order to omit repetition of explanation, the description of the imaging unit 18 disposed above the car 1 is omitted. Further, in this embodiment, differences from the configuration, function, and operation disclosed in Embodiment 1 will be described in detail. For configurations, functions, and operations not disclosed in the present embodiment, any configuration, function, and operation disclosed in Embodiment 1 may be employed, if applicable.

19 is a diagram for explaining the functions of the camera unit 33. Also in the example shown in the present embodiment, the camera unit 33 includes a camera 41, a cover 42, a magnet 43, a power supply line 44, and an antenna 45 as shown in FIGS. 2 and 5 . , and a control device 46. In addition to the storage unit 60 and the communication unit 61, the control device 46 further includes a shooting condition determination unit 63 and a communication detection unit 64.

20 is a diagram for explaining the functions of the lamp unit 31 . In the example shown in this embodiment, the lamp unit 31 further includes a visible light lamp 54, an infrared lamp 55, and a control device 56. The control device 56 includes a selection unit 110, an emission control unit 111, a communication unit 112, and a switching condition determination unit 113. The external appearance of the lamp unit 31 is the same as the example shown in FIG. 4, for example.

The visible light lamp 54 emits visible light. The visible light lamp 54 is an example of means capable of emitting visible light. For example, a white LED is employed as the visible light lamp 54 . At least a part of the visible light from the visible light lamp 54 is emitted downward. The visible light lamp 54 is controlled by the emission controller 111.

The infrared lamp 55 emits infrared rays. The infrared lamp 55 is an example of means capable of emitting infrared rays. For example, as the infrared lamp 55, an infrared LED is employed. At least a part of the infrared rays from the infrared lamp 55 is radiated downward. The infrared lamp 55 is controlled by the emission controller 111.

The camera 41 of the camera unit 33 shown in this embodiment is capable of both visible light imaging and infrared imaging. For example, the camera 41 can take pictures with visible light from the visible light lamp 54 . The camera 41 is capable of imaging by infrared rays from the infrared lamp 55 .

The selector 110 selects a light source. For example, the selector 110 selects the visible light lamp 54 or the infrared lamp 55 as a light source. The radiation controller 111 emits electromagnetic waves from the light source selected by the selector 110 . That is, when the selector 110 selects the visible light lamp 54, the emission controller 111 emits visible light from the visible light lamp 54. The radiation controller 111 emits infrared rays from the infrared lamp 55 when the selector 110 selects the infrared lamp 55 .

The communication unit 112 is responsible for the communication function of the lamp unit 31 . The communication unit 112 communicates with the communication unit 61 of the camera unit 33 . Further, communication between the lamp unit 31 and the portable terminal 13 may be performed directly or through the camera unit 33 . Communication between the lamp unit 31 and the monitoring device 8 may be performed through the camera unit 33 and the access point 12 or not through the camera unit 33 but through the access point 12. .

21 is a flowchart showing an example of the basic operation of the imaging unit 19 in the second embodiment. In an elevator, automatic operation is normally performed. If the interior of the hoistway 3 is illuminated during automatic driving, users may feel the light suspiciously. For this reason, if automatic operation is performed in the elevator, the selector 110 selects the infrared lamp 55 as a light source (S901).

The shooting condition judging unit 63 determines whether the shooting conditions are met (S902). As described above, shooting conditions are set in advance. In the example shown in the present embodiment, the determination may always be Yes in S902.

If yes is determined in S902, the radiation control unit 111 emits infrared rays from the infrared lamp 55. In addition, if it is determined as Yes in S902, photographing by the camera 41 is performed (S903). When photographing by the camera 41 starts in S903, the control device 46 determines whether or not the communication unit 61 has received a signal for requesting transmission of video data (S904).

If the communication unit 61 is receiving the signal (Yes in S904), it transmits the video data to the requesting destination (S905). If the communication unit 61 is not receiving the corresponding signal (No in S904), the video data is stored in the storage unit 60 (S906). In S905, video data may be stored in the storage unit 60 simultaneously. In S906, video data may be stored in the monitoring device 8 or other devices.

While the selecting unit 110 is selecting the infrared lamp 55, the switching condition determining unit 113 determines whether the switching condition is satisfied (S907). Switching conditions are set in advance. As a switching condition, a specific time may be set. In this case, when the current time becomes the corresponding time, it is determined as Yes in S907. As another example, when the communication unit 112 receives a specific signal, a switching condition may be established. As another example, the switching condition may be established according to the operation mode of the elevator. If the conversion condition is met while the selector 110 is selecting the infrared lamp 55, the selector 110 selects the visible light lamp 54 as a light source (S908).

When the selection unit 110 selects the visible light lamp 54, the shooting condition determining unit 63 determines whether shooting conditions are met (S909). Shooting conditions for shooting with visible light are different from shooting conditions for shooting with infrared light. For example, if the communication unit 61 receives a specific signal, it is determined to Yes in S909. The photographing conditions for photographing with visible light may be the same as those for photographing with infrared light. For example, in S909, the determination may always be Yes.

If yes in S909, the emission controller 111 emits visible light from the visible light lamp 54. In addition, if it is judged as Yes in S909, photographing by the camera 41 is performed (S910). When photographing by the camera 41 starts in S910, the control device 46 determines whether or not the communication unit 61 has received a signal for requesting transmission of video data (S911).

If the communication unit 61 is receiving the signal (Yes in S911), it transmits the video data to the requesting destination (S912). If the communication unit 61 does not receive the corresponding signal (No in S911), the image data is stored in the storage unit 60 (S913). In S912, video data may be stored in the storage unit 60 simultaneously. In S913, video data may be stored in the monitoring device 8 or other equipment.

Even while the selection unit 110 is selecting the visible light lamp 54, the switching condition determining unit 113 determines whether or not the switching condition is satisfied (S914). The switching condition in S914 and the switching condition in S907 may be different conditions. If the switching condition is met while the selector 110 is selecting the visible light lamp 54, the selector 110 selects the infrared lamp 55 as a light source (S901).

22 is a diagram showing the functions of the control device 7 and the monitoring device 8. In addition to the storage unit 80 and the operation control unit 82, the control device 7 further includes a display control unit 83. The display control unit 83 controls the display device 26 . In the example shown in this embodiment, power is always supplied to the socket 17 . Therefore, the control device 7 does not have to have the function of the power supply unit 81 that controls power supply to the socket 17 and power cutoff. The control device 7 includes a power supply unit 81, and power supply to the socket 17 may be always performed by the power supply unit 81.

In addition to the storage unit 90, the condition determination unit 91, and the communication unit 92, the monitoring device 8 further includes an abnormality detection unit 93, a person detection unit 94, and a prohibition unit 95.

23 is a diagram showing an example of the portable terminal 13. As shown in FIG. The portable terminal 13 further includes a signal generator 75 in addition to the example shown in FIG. 8 . 24 is a diagram showing an example of the external device 11 . The external device 11 further includes a signal generator 105 in addition to the example shown in FIG. 12 .

Next, an example of using an image captured by the camera 41 will be described.

In the lamp unit 31, when automatic operation is performed in the elevator, the selector 110 selects the infrared lamp 55 (S901). For example, while automatic driving is being performed, it is determined Yes in S902 and No in S904. In this case, if the automatic driving is being performed, the infrared image photographed by the camera 41 is continuously stored in the storage unit 60 .

25 is a flowchart showing an example of the operation of the portable terminal 13. In the mobile terminal 13, it is determined whether or not a wireless connection with the camera unit 33 has been established (S1001). When the maintenance worker performs a specific authentication operation on the portable terminal 13, the portable terminal 13 is connected to the camera unit 33 (Yes in S1001). In the mobile terminal 13, when connected to the camera unit 33, it is determined whether there is a request for a visible light video (S1002).

As an example, the display 71 of the portable terminal 13 displays a first button for maintenance personnel to press when they want to view a visible light image in the hoistway 3 . The first button is an example of an input device 70 . If the first button is pressed, it is determined as Yes in S1002. If yes is determined in S1002, the signal generator 75 generates a first signal for selecting the visible light lamp 54 in the selector 110 (S1003). The communication unit 74 transmits the first signal generated by the signal generation unit 75 to the lamp unit 31 and the camera unit 33 (S1004).

In the lamp unit 31, when the communication unit 112 receives the first signal from the portable terminal 13 while the selection unit 110 is selecting the infrared lamp 55, the switching condition judgment determines that the switching condition is established. The government 113 makes a decision (Yes in S907). By this, the selector 110 selects the visible light lamp 54 in S908. Also, when the communication unit 61 receives the first signal from the portable terminal 13, it is determined as Yes in S909 and Yes in S911. In S912, the communication unit 61 transmits the video data by the camera 41 to the mobile terminal 13.

In the mobile terminal 13, when the first signal is transmitted in S1004, it is determined whether video data has been received from the camera unit 33 (S1005). The video data transmitted by the communication unit 61 in S912 is received by the communication unit 74 (Yes in S1005). The display control unit 73 displays an image captured by the camera 41, that is, a visible light image, on the display 71 based on the image data received by the communication unit 74 from the camera unit 33 (S1006) .

If communication between the mobile terminal 13 and the camera unit 33 is not disconnected (No in S1007), the processing of the mobile terminal 13 returns to S1002. In the mobile terminal 13, if it is not determined as Yes in S1002, it is determined whether there is a request for an infrared image (S1008).

The display 71 of the portable terminal 13 displays a second button for maintenance personnel to press when they want to see an infrared image inside the hoistway 3 . The second button is an example of the input device 70 . If the second button is pressed while the portable terminal 13 is connected to the camera unit 33, a determination is made of Yes in S1008. If yes is determined in S1008, the signal generator 75 generates a second signal for selecting the infrared lamp 55 in the selector 110 (S1009). The second signal is a different signal from the first signal. The communication unit 74 transmits the second signal generated by the signal generation unit 75 to the lamp unit 31 and the camera unit 33 (S1010).

In the lamp unit 31, when the communication unit 112 receives the second signal from the portable terminal 13 while the selector 110 is selecting the visible light lamp 54, the switching condition judgment determines that the switching condition is established. The government 113 makes a decision (Yes in S914). By this, the selector 110 selects the infrared lamp 55 in S901. Also, when the communication unit 61 receives the second signal from the portable terminal 13, it is determined as Yes in S902 and Yes in S904. In S905, the communication unit 61 transmits the video data by the camera 41 to the portable terminal 13.

In the portable terminal 13, when the second signal is transmitted in S1010, it is determined whether video data has been received from the camera unit 33 (S1005). The video data transmitted by the communication unit 61 in S905 is received by the communication unit 74 (Yes in S1005). The display control unit 73 displays an image taken by the camera 41, that is, an infrared image, on the display 71 based on the image data received by the communication unit 74 from the camera unit 33 (S1006).

When communication between the portable terminal 13 and the lamp unit 31 and camera unit 33 is disconnected (Yes in S1007), the portable terminal 13 ends the process. In the lamp unit 31 , when communication with the portable terminal 13 is disconnected, the selector 110 selects the infrared lamp 55 .

26 is a flowchart showing another operation example of the portable terminal 13. When the portable terminal 13 performs the operation shown in FIG. 26 , the control device 46 of the camera unit 33 is provided with a communication detection unit 64 . The communication detection unit 64 detects that communication between the communication unit 61 and a specific device has been established.

In the portable terminal 13, it is determined whether or not a wireless connection with the camera unit 33 has been established (S1101). When the maintenance worker performs a specific authentication operation on the portable terminal 13, the portable terminal 13 is connected to the camera unit 33 (Yes in S1101). When the portable terminal 13 is connected to the camera unit 33, the portable terminal 13 determines whether video data has been received from the camera unit 33 (S1102).

In the lamp unit 31, when automatic operation is performed in the elevator, the selector 110 selects the infrared lamp 55 (S901). As an example, an infrared image captured by the camera 41 is stored in the storage unit 60 while autonomous driving is being performed. Further, when the mobile terminal 13 is connected to the camera unit 33, the establishment of communication between the communication unit 61 and the portable terminal 13 is detected by the communication detection unit 64.

When it is detected by the communication detection unit 64 that communication between the communication unit 61 and the portable terminal 13 is established when the selection unit 110 selects the infrared lamp 55, the switching condition indicates that the switching condition is established. The decision unit 113 makes a decision (Yes in S907). With this, the selector 110 selects the visible light lamp 54 in S908. Also, if the above detection by the communication detection unit 64 is made, it is determined as Yes in S909 and Yes in S911. In S912, the communication unit 61 transmits the video data by the camera 41 to the mobile terminal 13.

The video data transmitted by the communication unit 61 in S912 is received by the communication unit 74 in the portable terminal 13 (Yes in S1102). The display control unit 73 displays the visible light image captured by the camera 41 on the display unit 71 based on the video data received by the communication unit 74 from the camera unit 33 (S1103).

Next, the portable terminal 13 determines whether there is a request for an infrared image (S1104). For example, when the second button is pressed, it is determined as Yes in S1104. If yes is determined in S1104, the signal generator 75 generates a second signal (S1105). The communication unit 74 transmits the second signal generated by the signal generation unit 75 to the lamp unit 31 and the camera unit 33 (S1106).

In the lamp unit 31, when the communication unit 112 receives the second signal from the portable terminal 13 while the selector 110 is selecting the visible light lamp 54, the switching condition judgment determines that the switching condition is established. The government 113 makes a decision (Yes in S914). By this, the selector 110 selects the infrared lamp 55 in S901. Also, when the communication unit 61 receives the second signal from the portable terminal 13, it is determined as Yes in S902 and Yes in S904. In S905, the communication unit 61 transmits the video data by the camera 41 to the portable terminal 13.

In the portable terminal 13, if communication with the camera unit 33 is not disconnected (No in S1107), after transmitting the second signal in S1106, it is determined whether or not video data has been received from the camera unit 33. It becomes (S1102). The video data transmitted by the communication unit 61 in S905 is received by the communication unit 74 in the portable terminal 13 (Yes in S1102). The display control unit 73 displays the infrared image captured by the camera 41 on the display 71 based on the image data received by the communication unit 74 from the camera unit 33 (S1103).

In the portable terminal 13, if it is not determined as Yes in S1104, it is determined whether there is a request for visible light video (S1108). For example, if the first button is pressed, it is determined as Yes in S1108. If yes is determined in S1108, the signal generator 75 generates a first signal (S1109). The communication unit 74 transmits the first signal generated by the signal generation unit 75 to the lamp unit 31 and the camera unit 33 (S1110). This makes it possible to display the visible light image captured by the camera 41 on the display unit 71 of the portable terminal 13 .

When communication between the portable terminal 13 and the lamp unit 31 and camera unit 33 is disconnected (Yes in S1107), the portable terminal 13 ends the process. In the lamp unit 31 , when communication with the portable terminal 13 is disconnected, the selector 110 selects the infrared lamp 55 .

Next, as another example of using the image captured by the camera 41, an example in which a supervisor in the monitoring center 10 views the image captured by the camera 41 through the external device 11 will be described.

In the lamp unit 31, when automatic operation is performed in the elevator, the selector 110 selects the infrared lamp 55 (S901). For example, an infrared image captured by the camera 41 is stored in the storage unit 60 while autonomous driving is being performed.

In the external device 11, the same operation as shown in Fig. 25 is performed. For example, in the external device 11, it is determined whether or not it is connected to the camera unit 33 (S1001). A supervisor of the monitoring center 10 connects the external device 11 to the camera unit 33 when wanting to view the video captured by the camera 41 on the display device 101 . For example, the external device 11 and the monitoring device 8 are wired connected via the network 9 . The monitoring device 8 and the camera unit 33 are wirelessly connected via the access point 12 .

In the external device 11, when connected to the camera unit 33, it is determined whether or not there is a request for visible light video (S1002). As an example, a third button for a supervisor to press when he or she wants to see a visible light image in the hoistway 3 is displayed on the indicator 101 of the external device 11 . The third button is an example of the input device 100 . If the third button is pressed, it is determined as Yes in S1002. If yes is determined in S1002, the signal generator 105 generates a first signal (S1003). The communication unit 104 transmits the first signal generated by the signal generation unit 105 to the lamp unit 31 and the camera unit 33 (S1004).

When the communication unit 112 receives the first signal from the external device 11 while the selection unit 110 is selecting the infrared lamp 55, a decision is made as Yes in S907, and the selection unit 110 selects the visible light lamp in S908. Choose (54). Also, when the communication unit 61 receives the first signal from the external device 11, it is determined Yes in S909 and Yes in S911. In S912, the communication unit 61 transmits the video data by the camera 41 to the external device 11. Specifically, the communication unit 61 transmits video data to the monitoring device 8 via the access point 12 . The monitoring device 8 transmits video data received from the camera unit 33 via the access point 12 to the external device 11 via the network 9 .

In the external device 11, when the first signal is transmitted in S1004, it is determined whether video data has been received from the camera unit 33 (S1005). The video data transmitted by the communication unit 61 in S912 is received by the communication unit 104 (Yes in S1005). Based on the video data received by the communication unit 104 from the camera unit 33, the display control unit 103 displays an image captured by the camera 41, that is, a visible light image, on the display unit 101 (S1006). .

If communication between the external device 11 and the camera unit 33 is not disconnected (No in S1007), the processing of the external device 11 returns to S1002. In the external device 11, if it is not determined as Yes in S1002, it is determined whether there is a request for an infrared image (S1008).

As an example, the display 101 of the external device 11 displays a fourth button for the supervisor to press when he or she wants to view an infrared image inside the hoistway 3 . The fourth button is an example of the input device 100 . If the fourth button is pressed while the external device 11 is connected to the camera unit 33, a determination is made of Yes in S1008. If yes is determined in S1008, the signal generation unit 105 generates a second signal for selecting the infrared lamp 55 in the selection unit 110 (S1009). The communication unit 104 transmits the second signal generated by the signal generation unit 105 to the lamp unit 31 and the camera unit 33 (S1010).

When the communication unit 112 receives the second signal from the external device 11 while the selector 110 is selecting the visible light lamp 54, a decision is made in S914 to Yes, and the selector 110 selects the infrared ray in S901. Select Ramp 55. Also, when the communication unit 61 receives the second signal from the external device 11, it is determined as Yes in S902 and Yes in S904. In S905, the communication unit 61 transmits the video data by the camera 41 to the external device 11.

In the external device 11, when the second signal is transmitted in S1010, it is determined whether video data has been received from the camera unit 33 (S1005). The video data transmitted by the communication unit 61 in S905 is received by the communication unit 104 (Yes in S1005). The display control unit 103 displays an image taken by the camera 41, that is, an infrared image, on the display 101 based on the image data received by the communication unit 104 from the camera unit 33 (S1006).

When communication between the external device 11, the lamp unit 31, and the camera unit 33 is disconnected (Yes in S1007), the external device 11 ends the processing. In the lamp unit 31 , when communication with the external device 11 is disconnected, the selector 110 selects the infrared lamp 55 .

In the external device 11, the same operation as shown in Fig. 26 may be performed. In this case, the control device 46 of the camera unit 33 is provided with a communication detection unit 64. That is, if it is detected by the communication detection unit 64 that communication between the communication unit 61 and the external device 11 has been established while the selection unit 110 is selecting the infrared lamp 55, it is determined as Yes in S907. . As a result, the image captured by the camera 41, that is, the visible light image is displayed on the display device 101 (S1103).

Next, an example of using the image captured by the camera 41 according to the driving mode of the elevator will be described. In the monitoring device 8, the operation shown in FIG. 16 is performed. That is, while the automatic driving is being performed by the driving control unit 82, the condition determination unit 91 determines whether or not the diagnosis condition is satisfied (S601). If yes is determined in S601, the communication unit 92 transmits the first mode signal to the control device 7, lamp unit 31, and camera unit 33 (S602).

When receiving the first mode signal from the monitoring device 8, the control device 7 starts diagnostic operation. In diagnostic operation, diagnostic data is acquired. The control device 7 transmits diagnostic data obtained in the diagnostic operation to the monitoring device 8 .

In the lamp unit 31, when automatic operation is performed in the elevator, the selector 110 selects the infrared lamp 55 (S901). For example, an infrared image captured by the camera 41 is stored in the storage unit 60 while autonomous driving is being performed.

When the communication unit 112 receives the first mode signal from the monitoring device 8 when the selection unit 110 selects the infrared lamp 55, the decision is made as Yes in S907, and the selection unit 110 selects visible light in S908. Select Ramp 54. That is, when diagnostic operation is performed in the elevator, the selector 110 selects the visible light lamp 54 . In addition, when the communication unit 61 receives the first mode signal from the monitoring device 8, it is determined as Yes in S909 and Yes in S911. In S912, the communication unit 61 transmits the video data obtained by the camera 41 to the monitoring device 8 as diagnosis data.

In the monitoring device 8, after the communication unit 92 transmits the first mode signal in S602, it is determined in S604 whether diagnostic data has been received. The diagnostic data transmitted by the control device 7 is received by the communication unit 92 (Yes in S604). If the monitoring device 8 and the camera unit 33 are connected (Yes in S603), the video data (data for diagnosis) transmitted by the communication unit 61 in S912 is received by the communication unit 92 (Yes in S604). ). The diagnostic data received by the communication unit 92 is stored in the storage unit 90 (S605).

When the diagnosis operation by the operation control unit 82 is completed (Yes in S606), the communication unit 92 transmits a second mode signal for setting the operation mode to the automatic mode to the control device 7, the lamp unit 31 and the camera. It is transmitted to unit 33 (S607). In the control device 7, upon receiving the second mode signal from the monitoring device 8, the operation control unit 82 resumes the automatic driving.

In the lamp unit 31, when the communication unit 112 receives the second mode signal from the monitoring device 8 while the selection unit 110 is selecting the visible light lamp 54, a decision is made as Yes in S914, and the selection unit (110) selects the infrared lamp 55 in S901. In this example, image data by the camera 41 can be included in the diagnosis data. In the monitoring device 8, the operation shown in FIG. 17 may be performed separately.

27 is a flowchart showing another operation example of the monitoring device 8. FIG. 27 shows an example of an operation performed after the operation shown in FIG. 16 . Fig. 27 shows an example in which the presence or absence of an abnormality is determined in the monitoring device 8 based on the diagnostic data acquired in the diagnostic operation. When the operation shown in Fig. 27 is performed, the monitoring device 8 is equipped with an abnormality detection unit 93.

In the monitoring device 8, the abnormality detection unit 93 determines whether or not there is an abnormality based on the diagnostic data stored in the storage unit 90 (S1201). For example, the abnormality detection unit 93 detects an abnormality by comparing the diagnostic data with the corresponding reference value. When an abnormality is detected by the abnormality detection unit 93 (Yes in S120), the communication unit 92 transmits a signal indicating that the abnormality has been detected to the external device 11 (S1202).

28 is a flowchart showing another operation example of the monitoring device 8. The operation flow shown in FIG. 28 shows another example of using the video captured by the camera 41 according to the driving mode. While automatic driving is being performed by the driving control unit 82, the monitoring device 8 determines whether or not an earthquake has occurred (S1301). When data of acceleration representing a specific level is input from the seismograph 14, it is determined as Yes in S1301. When the seismograph 14 outputs an earthquake detection signal, when an earthquake detection signal is input from the seismometer 14, it is determined as Yes in S1301. If yes is determined in S1301, the communication unit 92 transmits a third mode signal for setting the driving mode to the control mode to the control device 7 (S1302).

When the third mode signal is received from the monitoring device 8, the control device 7 starts the earthquake control operation. Earthquake control operation is operation for evacuating passengers in the car 1 immediately after an earthquake occurs. In earthquake control operation, for example, the car 1 is stopped at the nearest floor and the door 21 is opened and closed.

In the monitoring apparatus 8, when the 3rd mode signal is transmitted in S1302, the condition determination part 91 determines whether recovery conditions are satisfied (S1303). Recovery conditions are set in advance. For example, if acceleration representing a specific level is detected by the seismometer 14 and the car 1 becomes unattended after the earthquake control operation is finished, the recovery condition is established. If the condition determination unit 91 determines that the recovery condition is satisfied (Yes in S1303), the communication unit 92 transmits a fourth mode signal for setting the operation mode to the recovery mode between the control device 7 and the lamp unit 31. ) and transmitted to the camera unit 33 (S1304).

When receiving the fourth mode signal from the monitoring device 8, the control device 7 starts recovery operation. That is, the operation control unit 82 performs recovery operation when recovery conditions are established. In the restoration operation, data for restoration necessary for determining whether the elevator is to be restored is obtained. The control device 7 transmits the recovery data acquired in the recovery operation to the monitoring device 8.

On the other hand, in the lamp unit 31, if automatic operation is performed in the elevator, the selector 110 selects the infrared lamp 55 (S901). For example, an infrared image captured by the camera 41 is stored in the storage unit 60 while autonomous driving is being performed.

When the communication unit 112 receives the fourth mode signal from the monitoring device 8 when the selection unit 110 selects the infrared lamp 55, the switching condition determining unit 113 determines that the switching condition is established. (Yes in S907). By this, the selector 110 selects the visible light lamp 54 in S908. That is, when recovery operation is performed in the elevator, the selector 110 selects the visible light lamp 54 . In addition, when the communication unit 61 receives the fourth mode signal from the monitoring device 8, it is determined as Yes in S909 and Yes in S911. In S912, the communication unit 61 transmits the video data obtained by the camera 41 to the monitoring device 8 as restoration data.

In the monitoring device 8, when the communication unit 92 transmits the fourth mode signal in S1304, it is determined whether recovery data has been received (S1305). The recovery data transmitted by the control device 7 is received by the communication unit 92 (Yes in S1305). The video data (data for restoration) transmitted by the communication unit 61 in S912 is received by the communication unit 92 (Yes in S1305). The recovery data received by the communication unit 92 is stored in the storage unit 90 (S1306). In this example, image data by the camera 41 may be included in the recovery data.

The abnormality detection unit 93 determines whether or not there is an abnormality based on the recovery data stored in the storage unit 90 (S1307). For example, the abnormality detection unit 93 detects an abnormality by comparing the data for recovery with the corresponding reference value. When an abnormality is detected by the abnormality detection unit 93 (Yes in S1307), the communication unit 92 transmits a signal indicating that the abnormality has been detected to the external device 11 (S1308).

When the recovery operation ends without any abnormality being detected by the abnormality detector 93 (Yes in S1309), the monitoring device 8 temporarily restores the elevator (S1310). In the provisional recovery, the operation control unit 82 establishes a certain limit such as a speed limit, and then performs an operation in which the car 1 responds to a registered call in sequence. Further, the display control unit 83 displays on the indicator 26 that the restoration is not complete.

If yes is determined in S1309, the monitoring device 8 acquires the video data after completion from the camera unit 33. The post-end video data is data representing a video taken by the camera 41 after the recovery operation is finished. The video data after completion is preferably visible light video data. When the monitoring device 8 acquires the post-video data from the camera unit 33, the communication unit 92 transmits the acquired post-video data to the external device 11 (S1311).

When video data is transmitted to the external device 11 after completion in S1311, the monitoring device 8 determines whether or not a recovery permission signal has been received from the external device 11 (S1312). In the monitoring center 10, based on the post-video data received by the external device 11, it is determined whether or not the elevator may be restored. This determination may be made, for example, by a plurality of people who have viewed the video. If it is determined that the elevator may be restored, a recovery permission signal is transmitted from the external device 11 .

Upon receiving the restoration permission signal from the external device 11 (Yes in S1312), the monitoring device 8 restores the elevator (S1313). In this restoration, the communication unit 92 transmits the second mode signal to the control device 7, the lamp unit 31, and the camera unit 33, for example. With this, the operation control unit 82 resumes normal operation. The display control unit 83 erases from the display unit 26 the display to the effect that restoration is not complete. In addition, in the lamp unit 31, the selector 110 selects the infrared lamp 55.

In FIG. 28, an example in which the elevator is fully restored when the monitoring device 8 receives a restoration permission signal from the external device 11 has been described. This is an example. As another example, the elevator may be restored manually by performing a specific operation by a maintenance worker who has visited the site. In addition, when the seismograph 14 is connected to the control device 7, the operation flow shown in FIG. 28 may be performed by the control device 7.

Fig. 29 is a flowchart showing another operation example of the monitoring device 8. The operation shown in Fig. 29 differs from the operation shown in Fig. 28 in the case where it is determined as No in S1303. Fig. 29 shows an example of using an image captured by the camera 41 when it is determined as No in S1303.

As described above, in S1303, it is determined whether or not recovery conditions have been established. For example, if yes is not determined in S1303 even after a certain period of time elapses after the earthquake control operation is finished, the monitoring device 8 acquires video data after the stop from the camera unit 33 . The post-stop image data is data representing an image captured by the camera 41 when the car 1 is stopped after the earthquake control operation is finished. The post-stop video data is preferably visible light video data. When the monitoring device 8 acquires the video data after the stop from the camera unit 33, the communication unit 92 transmits the acquired video data after the stop to the external device 11 (S1314).

When the video data after the stop is transmitted to the external device 11 in S1314, the monitoring device 8 determines whether or not a start signal has been received from the external device 11 (S1315). In the monitoring center 10, based on the post-stop video data received by the external device 11, it is determined whether recovery operation may be started in the elevator. This determination may be made, for example, by a plurality of people who have viewed the video. When it is determined that recovery operation may be started in the elevator, a start signal is transmitted from the external device 11 .

In the monitoring device 8, even if it is determined as No in S1303, if a start signal is received from the external device 11 (Yes in S1315), the communication unit 92 transmits a fourth mode signal to the control device 7 and the lamp. It is transmitted to the unit 31 and the camera unit 33 (S1304). In the control device 7, lamp unit 31, and camera unit 33 that have received the fourth mode signal, operations similar to those described with reference to FIG. 28 are performed. In addition, when the seismometer 14 is connected to the control device 7, the operation flow shown in FIG. 29 may be performed by the control device 7.

30 is a flowchart showing another example of the operation of the monitoring device 8. The operation flow shown in FIG. 30 shows another example of using the video captured by the camera 41 according to the driving mode.

While automatic driving is being performed by the driving control unit 82, the monitoring device 8 determines whether or not the maintenance mode has been set (S1401). For example, the operating panel 25 of the car 1 is provided with a switch 25b for setting the operation mode to the maintenance mode. The switch 25b is an example of means for setting the operation mode to the maintenance mode. The switch 25b may be provided in the control device 7 or the monitoring device 8. By performing a specific operation on the switch 25b, the operation mode is set to the maintenance mode. When the maintenance mode is set by the switch 25b (Yes in S1401), the person detection unit 94 determines whether or not there is a person in the hoistway 3 (S1402).

On the other hand, in the lamp unit 31, if automatic operation is performed in the elevator, the selector 110 selects the infrared lamp 55 (S901). For example, an infrared image captured by the camera 41 is stored in the storage unit 60 while autonomous driving is being performed.

If the operation mode is set to the maintenance mode while the selection unit 110 is selecting the infrared lamp 55, the switching condition determining unit 113 determines that the switching condition is established (Yes in S907). By this, the selector 110 selects the visible light lamp 54 in S908. Also, if the operation mode is set to the maintenance mode, it is determined Yes in S909 and Yes in S911. In S912, the communication unit 61 transmits video data from the camera 41 to the monitoring device 8.

The video data transmitted from the communication unit 61 is received by the communication unit 92 in the monitoring device 8 . The person detection unit 94 detects that there is a person in the hoistway 3 based on the video data received by the communication unit 92 (Yes in S1402). For example, the person detection unit 94 detects that there is a person in the pit 3a of the hoistway 3 based on video data received from the camera unit 33 . The person detection unit 94 detects that there is a person on top of the car 1 based on video data received from the camera unit of the imaging unit 18 .

When it is detected by the person detection unit 94 that there is a person in the hoistway 3, the prohibition unit 95 prohibits the automatic operation from being performed (S1403). For example, the movable range of the car 1 in automatic operation is wider than the movable range of the car 1 in maintenance mode. If it is the example shown in FIG. 30, it can prevent automatic operation from starting despite the presence of people in the hoistway 3.

When the presence of a person in the hoistway 3 is detected by the person detection unit 94, a notification may be given to the person in the hoistway 3 according to the position of the car 1. For example, when it is detected by the person detection unit 94 that there is a person in the hoistway 3, the emission control unit 111 determines the emission mode of visible light from the visible light lamp 54 according to the position of the car 1. Change the For example, the emission control unit 111 controls the visible light lamp 54 so that the flashing speed increases as the car 1 approaches the pit 3a. The emission control unit 111 may change the color of light emitted from the visible light lamp 54 according to the position of the car 1 .

As another example, when it is detected by the person detection unit 94 that there is a person in the hoistway 3, the sound control unit 62 may output a sound from the speaker 48 according to the position of the car 1. For example, the sound controller 62 generates a warning sound from the speaker 48 when the car 1 is disposed at a position lower than a certain height. Thereby, attention can be urged to people in the hoistway 3.

Next, an example of realizing the above elevator system by remodeling an existing elevator will be described. 31 is a flow chart showing an example of a method for repairing elevators. The procedures shown in S801 to S806 in Fig. 31 are the same as those shown in S801 to S806 in Fig. 18 .

As described above, in the elevator before renovation, a light bulb for illuminating the inside of the hoistway 3 is provided in the car 1 through the socket 17. For this reason, it cannot be said that power supply to the socket 17 is always performed in the elevator before repair. In S807, the maintenance worker changes the setting so that electric power is constantly supplied to the lamp unit 31 and the camera unit 33 via the socket 17.

Next, the maintenance worker establishes communication between the communication unit 61 and the access point 12 so that the camera unit 33 can transmit video data to the monitoring device 8 via the access point 12 ( S808). Further, communication between the communication unit 112 and the access point 12 is established as necessary.

The procedure shown in S809 and S810 in FIG. 31 is adopted as needed. If the car 1 is provided with a metal apron, a step of replacing the existing metal apron with a light-transmitting apron 22 may be further included (S809). Thereby, the video of the part covered by the apron 22 can be photographed by the camera 41.

A step of newly adding the signal generator 75 to the mobile terminal 13 of the maintenance worker may be further provided (S810). This makes it possible to select the visible light lamp 54 in the selector 110 through an operation from the mobile terminal 13, and display a visible light image by the camera 41 on the display unit 71. Similarly, a step of newly adding the signal generator 105 to the external device 11 may be further provided (S810). In this way, the visible light image by the camera 41 can be displayed on the display device 101 by causing the selector 110 to select the visible light lamp 54 by operation from the external device 11 .

The procedure shown in S808 and the procedure shown in S809 may be employed in the example disclosed in Embodiment 1.
