Next, an example of using an image captured by the camera 41 will be described. As noted above, the operation of video unit 19 is similar to the operation of video unit 18 . Therefore, in this embodiment and other embodiments, a detailed description of an example of using an image captured by a camera provided in the camera unit of the image unit 18 will be omitted.

FIG. 7 is a flowchart showing an operation example of the image unit 19. As shown in FIG. As an example, the control panel 25 of the car 1 is provided with a switch 25 a for supplying power to the socket 17 . The switch 25 a may be provided in the control device 7 or the monitoring device 8 . Power is supplied to the socket 17 when a specific operation is performed on the switch 25a. For example, the switch 25a can be manually switched on or off. If switch 25a is off, no power is supplied to socket 17; If the socket 17 is not powered, no light will be emitted from the lamp unit 31 . If power is not supplied to the socket 17, the camera 41 will not take pictures.

The switch 25a is basically off. Maintenance personnel turn on the switch 25a inside 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 video unit 19 (S101). That is, power is supplied to the lamp unit 31 through the socket 17 and the adapter 30 . Thereby, visible light is emitted from the lamp unit 31 (S102). Power is also supplied to the camera unit 33 via the socket 17 and the adapter 30 . This causes the camera 41 to start photographing (S103). For example, the camera 41 takes an image of the pit 3a.

The communication unit 61 has a function of transmitting video data. The image data is data representing an image captured by the camera 41 . After the switch 25a is turned on, that is, after power is supplied to the camera unit 33, the communication section 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 or not there is a connection with another device, that is, whether or not communication with another device has been established (S104).

The maintenance worker wirelessly connects the mobile terminal 13 to the camera unit 33 by performing a specific authentication operation on the mobile terminal 13 . FIG. 8 is a diagram showing an example of the mobile terminal 13. As shown in FIG. FIG. 9 is a flow chart showing an operation example of the mobile terminal 13 . The mobile terminal 13 has an input device 70 and a display 71 . A 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. 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 section 73 controls the display device 71 .

For example, when the communication unit 74 receives radio waves from the antenna 45 , the display control unit 73 displays information for specifying the camera unit 33 on the display 71 . The maintenance staff uses the input device 70 to specify the information and enter the password. The communication section 74 transmits the entered password to the camera unit 33 . The mobile terminal 13 determines whether or not it is connected to the camera unit 33 (S201).

When the communication unit 61 receives the correct password from the mobile terminal 13, the camera unit 33 and the mobile terminal 13 are wirelessly connected. As a result, a determination of Yes is made in S104. Moreover, it is determined as Yes in S201. If it is determined as Yes in S104, the communication unit 61 transmits data representing the image captured by the camera 41, that is, the image data captured by the camera 41 to the mobile terminal 13 (S105).

If it is determined as Yes in S201, the portable 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 causes the display 71 to display the image captured by the camera 41 based on the image data received by the communication unit 74 from the camera unit 33 (S203). As a result, the maintenance worker can view the real-time image of the pit 3a while riding in the car 1.

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

In the image unit 19, if power is supplied, the processing shown from S102 to S105 is repeatedly performed. When the maintenance person turns off the switch 25a, power to the video unit 19 is cut off (Yes in S106). If determined as Yes in S106, the video unit 19 ends the process.

Note that in the image unit 19, the camera 41 may start photographing after the determination in S104 is Yes. For example, photographing by the camera 41 may be started by receiving a specific signal from the mobile terminal 13 after communication between the camera unit 33 and the mobile terminal 13 is established. At this time, the image quality of the camera 41 may be set according to the communication status between the camera unit 33 and the mobile terminal 13 .

In the example shown in this embodiment, power is supplied to the video unit 19 via the socket 17 . Therefore, power can be supplied to the video unit 19 using existing equipment or design. In the example shown in this embodiment, it is possible to easily secure the power supply for the video unit 19, especially the power supply for the camera 41. FIG.

Other features that the elevator system can employ are described below. If possible, the elevator system may employ a combination of the following functions. Elevator systems disclosed in other embodiments can similarly employ the functions described later.

First, functions that can be employed by the video unit 19 will be described. For example, the imaging unit 19 does not need to include the lamp unit 31 if the brightness required for shooting can be secured without the lamp unit 31 . Also, the camera unit 33 may have the function of the lamp unit 31 .

As another example, the body 35 of the adapter 30 may be provided with a plurality of sockets 38 for light bulbs. In such a case, the main body 35 may not have 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 . The camera unit 33 can be fixed to the socket 38 if the power supply line 44 includes a cap that can be attached to and detached from the socket 38 . In order to connect the plug 44a to the socket 38, other adapters with a base detachable from the socket 38 and an outlet into which the plug 44a can be plugged may also be used.

As another example, the camera unit 33 may further include a communication line for communicating with other equipment. Maintenance personnel may connect equipment for maintenance to this communication line to update programs and the like. This communication line need not be used when maintenance personnel view the video of the pit 3a on the portable terminal 13. FIG. In such a case, it is preferable to attach a dustproof cap to the connector provided at the tip of the communication line.

FIG. 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 . One or more of microphone 47, speaker 48, accelerometer 49, gyro sensor 50, barometer 51, thermometer 52, and hygrometer 53 may be provided in camera unit 33 as needed. .

Microphone 47 detects sound. When the camera unit 33 is equipped with the microphone 47 , the communication section 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 control section 62 provided in the control device 46 .

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

A gyro sensor 50 detects the angular velocity of the camera unit 33 . If the camera unit 33 includes the gyro sensor 50 , the communication section 61 may transmit angular velocity data detected by the gyro sensor 50 to the mobile terminal 13 together with video data. Based on the acceleration data or the angular velocity data received by the portable terminal 13, the maintenance staff can confirm whether there is a problem with the ride comfort.

The barometer 51 detects the atmospheric pressure at the place where the barometer 51 is arranged. When the camera unit 33 includes the barometer 51 , the communication unit 61 may transmit the data of the atmospheric pressure detected by the barometer 51 to the mobile terminal 13 together with the video data. If the mobile terminal 13 is also provided with a barometer (not shown), the pressure detected by the barometer 51 and the pressure detected by the barometer provided in the mobile terminal 13 are calculated based on the position of the car 1 . difference can be used to more accurately identify the location of maintenance personnel.

The thermometer 52 detects the temperature at the location where the thermometer 52 is arranged. When the camera unit 33 includes the thermometer 52 , the communication section 61 may transmit the temperature data detected by the thermometer 52 to the portable terminal 13 together with the video data. The hygrometer 53 detects the humidity of the place where the hygrometer 53 is arranged. When the camera unit 33 includes the hygrometer 53, the communication unit 61 may transmit the humidity data detected by the hygrometer 53 to the mobile terminal 13 together with the video data. By using the temperature data and the humidity data received by the mobile terminal 13, it is possible to predict the life of the substrate provided in the control device 7 or the like.

In the above example, power is supplied to the video unit 19 by manually operating the switch 25a. As another example, the power supply to the video unit 19 may be implemented by the functions of the control device 7 and the monitoring device 8 . A specific example in which the control device 7 and the monitoring device 8 realize the power supply function for the video unit 19 will be described below with reference to FIGS. 11 to 16 as well.

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

The operation control unit 82 performs operation control according to the set operation mode. Operation modes include, for example, automatic mode, maintenance mode, diagnostic mode, control mode, and recovery mode. In automatic mode, automatic driving is performed. Automatic operation is operation in which car 1 responds to registered calls in sequence. In maintenance mode, it is possible to move the car 1 by manual operation. In the diagnostic mode, diagnostic operation is performed to determine the presence or absence of an abnormality. For example, diagnostic runs are performed periodically. In the control mode, for example, an earthquake control operation is performed. Earthquake control operations are performed immediately after an earthquake occurs. In the recovery mode, recovery operation is performed to determine whether the elevator can be recovered. Restoration operation is performed after earthquake control operation is performed.

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

FIG. 12 is a diagram showing an example of the external device 11. As shown in FIG. The external device 11 has an input device 100 and a display device 101 . A supervisor at the monitoring center 10 inputs necessary information from the input device 100 . The input device 100 and the display device 101 may be a touch panel type integrated device.

The display control unit 103 controls the display device 101 .

FIG. 13 is a flow chart showing an operation example of the control device 7 . If the interior of the hoistway 3 shines during automatic operation, the user may feel suspicious of the light. Therefore, the power supply unit 81 basically cuts off the power supply to the socket 17 (S301). As described above, no light is emitted from the lamp unit 31 unless power is supplied to the socket 17 . If power is not supplied to the socket 17, the camera 41 will not take pictures. 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). When determined as No in S<b>302 , the power supply unit 81 continues to cut off power to the socket 17 .

FIG. 14 is a flow chart showing an operation example of the monitoring device 8 . The condition determination unit 91 determines whether or not the imaging conditions are satisfied (S401). The imaging conditions are set in advance. A specific time period may be set as an imaging condition. In such a case, if the current time is included in the time zone, the determination in S401 is Yes.

As another example, the imaging condition may be established when the communication unit 92 receives a specific signal from the external device 11 . FIG. 15 is a flow chart showing an operation example of the external device 11 . As an example, a supervisor at the surveillance center 10 inputs specific information from the input device 100 when he/she wants to see an image captured by the camera 41 on the display 101 . When the information is input from the input device 100, the communication unit 104 transmits a second request signal for requesting video data from 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 shooting conditions are established (Yes in S401). If 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 determined as Yes in S302, the power supply unit 81 supplies power to the socket 17 (S303).

In the video unit 19, the operation shown in FIG. 7 is performed. That is, power is supplied from the socket 17 to the video unit 19 by the processing in S303 (S101). Thereby, visible light is emitted from the lamp unit 31 (S102). Further, 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 . After the communication unit 92 transmits the first request signal in S402, when the communication unit 92 receives radio waves from the antenna 45 via the access point 12, the monitoring device 8 and the camera unit 33 are connected after specific authentication processing. (Yes in S403). As a result, a determination of Yes is also made in S104. When it is determined as Yes in S104, the communication unit 61 transmits the image data from 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 imaging 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 in S404 to the external device 11 (S405).

In the external device 11, when the communication unit 104 transmits the second request signal in S501, it is determined whether or not 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 causes the display device 101 to display the image captured by the camera 41 based on the image data received by the communication unit 104 from the monitoring device 8 (S503). Thereby, the surveillance staff can see the real-time image of the pit 3a at the surveillance center 10. FIG.

Further, in the monitoring device 8, after the photographing condition is satisfied in S401, it is determined whether or not the termination condition for terminating the photographing is satisfied (S406). A termination condition is set in advance. When a specific time period is set as the shooting condition, the end condition is met if the current time is outside this time period. As another example, the end condition may be satisfied when the determination in S403 is No for a certain period of time. The termination condition may be met when a specific signal is received from the external device 11 . When 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).

After determining Yes in S302, the control device 7 determines whether or not the third request signal has been received from the monitoring device 8 (S304). When determined as No in S<b>304 , the power supply unit 81 continues power supply to the socket 17 . When the control device 7 receives the third request signal transmitted by the communication unit 92 in S407, a determination of Yes is made in S304. If determined as Yes in S304, the power supply unit 81 cuts off power to the socket 17 (S301).

Next, an example in which the surveillance staff of the surveillance center 10 views past images captured by the camera 41 will be described.

The operation shown in FIG. 13 is performed in the control device 7 . As described above, if the interior of the hoistway 3 lights up during automatic operation, the user may feel suspicious about the light. Therefore, the power supply unit 81 basically cuts off the power supply to the socket 17 (S301). For example, the power supply unit 81 cuts off power to the socket 17 while automatic operation is being performed. The controller 7 determines whether or not the first request signal has been received (S302).

FIG. 16 is a flow chart showing an operation example of the monitoring device 8 . While the operation control unit 82 is performing automatic operation, the condition determination unit 91 determines whether or not the diagnosis condition is satisfied (S601). Diagnosis conditions are set in advance. As an example, the diagnosis condition is met at a specific time on a specific day. When 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 operation mode to the diagnosis mode to the control device 7 (S602).

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

Also, the first mode signal transmitted by the communication unit 92 in S602 includes the first request signal. Therefore, when the control device 7 receives the first mode signal transmitted by the communication unit 92 in S602, the determination in S302 is Yes. If determined as Yes in S302, the power supply unit 81 supplies power to the socket 17 (S303).

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

The processes shown in S603 and S604 of FIG. 16 are the same as the processes shown in S403 and S404 of FIG. That is, when the communication unit 92 receives the radio wave 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 and the camera unit 33 are connected after specific authentication processing. are connected (Yes in S603). As a result, a determination of Yes is also made in S104. When it is determined as Yes in S104, the communication unit 61 transmits the image data from 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 because the diagnosis condition is satisfied, 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 operation control unit 82 ends (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 (S607). In the control device 7, when the second mode signal is received from the monitoring device 8, the operation control section 82 resumes automatic operation.

Also, the second mode signal transmitted by the communication unit 92 in S607 includes the third request signal.
Therefore, when the control device 7 receives the second mode signal transmitted by the communication unit 92 in S607, a determination of Yes is made in S304. If determined as Yes in S304, the power supply unit 81 cuts off power to the socket 17 (S301). Moreover, when it is determined as Yes in S304, it is determined as Yes in S106. In this example, the diagnostic data can include image data from the camera 41 .

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

In the monitoring device 8, it is determined whether or not the fourth request signal for requesting diagnostic data has been received (S701). As an example, a monitor at the monitoring center 10 inputs specific information from the input device 100 when he wants to acquire diagnostic data. When the information is input from the input device 100 , the communication section 104 transmits a fourth request signal to the monitoring device 8 via the network 9 . As another example, the communication section 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, a determination of Yes is made in S701. If determined as 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 S<b>702 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 image data from the camera 41 . The display control unit 103 causes the display device 101 to display the image captured by the camera 41 based on the image data received by the communication unit 104 from the monitoring device 8 . As a result, the surveillance staff can view the past images acquired in the diagnostic operation at the surveillance center 10 .

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 section 110 , a radiation control section 111 , a communication section 112 and a switching condition determination section 113 . The appearance of the lamp unit 31 is similar to the example shown in FIG. 4, for example.

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 part of the visible light from the visible light lamp 54 is emitted downward. The visible light lamp 54 is controlled by the radiation control section 111 .

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

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

The selection unit 110 selects a light source. For example, the selection unit 110 selects the visible light lamp 54 or the infrared lamp 55 as the light source. The radiation control unit 111 causes the light source selected by the selection unit 110 to emit electromagnetic waves. That is, when the selection unit 110 selects the visible light lamp 54 , the radiation control unit 111 causes the visible light lamp 54 to emit visible light. When the selection unit 110 selects the infrared lamp 55 , the radiation control unit 111 causes the infrared lamp 55 to emit infrared rays.

The communication section 112 controls the communication function of the lamp unit 31 . The communication section 112 communicates with the communication section 61 of the camera unit 33 . Communication between the lamp unit 31 and the mobile terminal 13 may be performed directly or via the camera unit 33 . Communication between the lamp unit 31 and the monitoring device 8 may be performed via the camera unit 33 and the access point 12 , or may be performed via the access point 12 without the camera unit 33 .

FIG. 21 is a flow chart showing an example of basic operation of the video unit 19 according to the second embodiment. Elevators are usually operated automatically. If the interior of the hoistway 3 shines during automatic operation, the user may feel suspicious of the light. Therefore, if the elevator is in automatic operation, the selector 110 selects the infrared lamp 55 as the light source (S901).

The imaging condition determination unit 63 determines whether or not the imaging conditions are satisfied (S902). As described above, the imaging conditions are set in advance. In the example shown in this embodiment, it may always be determined as Yes in S902.

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

If the signal is received (Yes in S904), the communication unit 61 transmits the video data to the request destination (S905). If the communication unit 61 has not received the signal (No in S904), the video data is stored in the storage unit 60 (S906). In S905, the video data may be saved in the storage unit 60 at the same time. In S906, the video data may be saved by the monitoring device 8 or another device.

While the selection unit 110 is selecting the infrared lamp 55, the switching condition determination unit 113 determines whether or not the switching condition is satisfied (S907). A switching condition is set in advance. A specific time may be set as the switching condition. In such a case, when the current time reaches the relevant time, S907 is determined to be Yes. As another example, the switching condition may be satisfied when the communication unit 112 receives a specific signal. As another example, the switching condition may be satisfied according to the operating mode of the elevator. If the switching condition is satisfied while the selection unit 110 selects the infrared lamp 55, the selection unit 110 selects the visible light lamp 54 as the light source (S908).

When the selection unit 110 selects the visible light lamp 54, the imaging condition determination unit 63 determines whether or not the imaging conditions are satisfied (S909). The imaging conditions for imaging with visible light are different from the imaging conditions for imaging with infrared light. For example, when the communication unit 61 receives a specific signal, S909 is determined to be Yes. The imaging conditions for imaging with visible light may be the same as the imaging conditions for imaging with infrared light. For example, S909 may always be determined as Yes.

When determined as Yes in S909, the radiation control unit 111 causes the visible light lamp 54 to emit visible light. Also, if it is determined as Yes in S909, photographing is performed by the camera 41 (S910). When the camera 41 starts photographing in S910, the control device 46 determines whether or not the communication section 61 has received a signal requesting transmission of video data (S911).

If the signal is received (Yes in S911), the communication unit 61 transmits the video data to the request destination (S912). If the communication unit 61 has not received the signal (No in S911), the video data is stored in the storage unit 60 (S913). In S912, the video data may be saved in the storage unit 60 at the same time. In S913, the video data may be saved by the monitoring device 8 or another device.

Even while the selection unit 110 is selecting the visible light lamp 54, the switching condition determination 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 satisfied while the selection unit 110 selects the visible light lamp 54, the selection unit 110 selects the infrared lamp 55 as the light source (S901).

For example, while automatic driving is being performed, it is determined as Yes in S902 and determined as No in S904. In such a case, the infrared image captured by the camera 41 continues to be stored in the storage unit 60 as long as automatic driving is being performed.

FIG. 25 is a flow chart showing an operation example of the mobile terminal 13 . The mobile terminal 13 determines whether or not it is wirelessly connected to the camera unit 33 (S1001). The mobile terminal 13 is connected to the camera unit 33 by the maintenance staff performing a specific authentication operation on the mobile terminal 13 (Yes in S1001). When the mobile terminal 13 is connected to the camera unit 33, it is determined whether or not there is a request for a visible light image (S1002).

As an example, the display 71 of the mobile terminal 13 displays a first button that the maintenance worker presses when he/she wants to see the visible light image inside the hoistway 3 . The first button is an example of the input device 70 . If the first button is pressed, a determination of Yes is made in S1002. When determined as Yes in S1002, the signal generator 75 generates a first signal for causing the selector 110 to select the visible light lamp 54 (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 determination unit 113 determines that the switching condition is satisfied (S907).

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 causes the display 71 to display the image captured by the camera 41, that is, the visible light image, 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 process 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 or not there is a request for infrared video (S1008).

A display 71 of the portable terminal 13 displays a second button that the maintenance worker presses when he/she wants to see the 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 mobile terminal 13 is connected to the camera unit 33, a determination of Yes is made in S1008. If determined as Yes in S1008, the signal generator 75 generates a second signal for causing the selector 110 to select the infrared lamp 55 (S1009). The second signal is a signal different 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 selection unit 110 is selecting the visible light lamp 54, the switching condition determination unit 113 determines that the switching condition is satisfied ( Yes in S914). Accordingly, the selection unit 110 selects the infrared lamp 55 in S901. Also, when the communication unit 61 receives the second signal from the mobile terminal 13, the determination in S902 is YES, and the determination in S904 is YES. In S<b>905 , the communication unit 61 transmits video data from the camera 41 to the mobile terminal 13 .

After transmitting the second signal in S1010, the mobile terminal 13 determines whether or not the 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 causes the display 71 to display the image captured by the camera 41, that is, the infrared image, based on the image data received by the communication unit 74 from the camera unit 33 (S1006).

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

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

The portable terminal 13 determines whether or not it is wirelessly connected to the camera unit 33 (S1101). The mobile terminal 13 is connected to the camera unit 33 by the maintenance staff performing a specific authentication operation on the mobile terminal 13 (Yes in S1101). When the mobile terminal 13 is connected to the camera unit 33, the mobile terminal 13 determines whether video data has been received from the camera unit 33 (S1102).

In the lamp unit 31, if the elevator is in automatic operation, 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 automatic driving is being performed. Also, when the mobile terminal 13 is connected to the camera unit 33 , the communication detection section 64 detects that communication between the communication section 61 and the mobile terminal 13 has been established.

When the communication detection unit 64 detects that communication has been established between the communication unit 61 and the mobile terminal 13 while the selection unit 110 is selecting the infrared lamp 55, the switching condition determination unit 113 detects that the switching condition is established. determines (Yes in S907). Accordingly, the selection unit 110 selects the visible light lamp 54 in S908. Further, when the above detection is made by the communication detection unit 64, it is determined Yes in S909 and Yes in S911. In S<b>912 , the communication unit 61 transmits video data from 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 causes the display 71 to display the visible light image captured by the camera 41 based on the image data received by the communication unit 74 from the camera unit 33 (S1103).

Next, the portable terminal 13 determines whether or not there is a request for infrared video (S1104). For example, if the second button is pressed, the determination in S1104 is Yes. If determined as Yes 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 selection unit 110 is selecting the visible light lamp 54, the switching condition determination unit 113 determines that the switching condition is satisfied ( Yes in S914). Accordingly, the selection unit 110 selects the infrared lamp 55 in S901. Also, when the communication unit 61 receives the second signal from the mobile terminal 13, the determination in S902 is YES, and the determination in S904 is YES. In S<b>905 , the communication unit 61 transmits video data from the camera 41 to the mobile terminal 13 .

If communication with the camera unit 33 is not disconnected (No in S1107), the portable terminal 13 determines whether video data has been received from the camera unit 33 after transmitting the second signal in S1106 ( 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 causes the display 71 to display the infrared image captured by the camera 41 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 or not there is a request for a visible light image (S1108). For example, if the first button is pressed, a determination of Yes is made in S1108. If determined as Yes in S1108, the signal generator 75 generates the 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). Thereby, the visible light image captured by the camera 41 can be displayed on the display 71 of the mobile terminal 13 .

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

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

In the lamp unit 31, if the elevator is in automatic operation, 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 automatic driving is being performed.

In the external device 11, the same operation as the operation shown in FIG. 25 is performed. For example, the external device 11 determines whether or not it is connected to the camera unit 33 (S1001). A supervisor at the surveillance center 10 connects the external device 11 to the camera unit 33 when he/she wants to see the video imaged by the camera 41 on the display device 101 . For example, the external device 11 and the monitoring device 8 are wire-connected via the network 9 . The monitoring device 8 and camera unit 33 are wirelessly connected via the access point 12 .

When the external device 11 is connected to the camera unit 33, it is determined whether or not there is a request for visible light video (S1002). As an example, the display 101 of the external device 11 displays a third button to be pressed when the observer wants to see the visible light image inside the hoistway 3 . A third button is an example of the input device 100 . If the third button is pressed, a determination of Yes is made in S1002. If determined as Yes 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).

If 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 determination of Yes is made in S907, and the selection unit 110 selects the visible light lamp 54 in S908. Also, when the communication unit 61 receives the first signal from the external device 11, the determination in S909 is YES, and the determination in S911 is YES. In S<b>912 , the communication unit 61 transmits video data from the camera 41 to the external device 11 . Specifically, the communication unit 61 transmits the 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, after transmitting the first signal in S1004, it is determined whether or not 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). The display control unit 103 causes the display 101 to display the image captured by the camera 41, that is, the visible light image, based on the image data received by the communication unit 104 from the camera unit 33 (S1006).

If communication between the external device 11 and the camera unit 33 is not disconnected (No in S1007), the process 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 or not there is a request for infrared video (S1008).

As an example, the display 101 of the external device 11 displays a fourth button to be pressed when the surveillance staff wants to see the infrared image inside the hoistway 3 . A 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 of Yes is made in S1008. If determined as Yes in S1008, the signal generation unit 105 generates a second signal for causing the selection unit 110 to select the infrared lamp 55 (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).

If the communication unit 112 receives the second signal from the external device 11 while the selection unit 110 is selecting the visible light lamp 54, a determination of Yes is made in S914, and the selection unit 110 selects the infrared lamp 55 in S901. Also, when the communication unit 61 receives the second signal from the external device 11, the determination in S902 is Yes, and the determination in S904 is Yes. In S<b>905 , the communication unit 61 transmits video data from the camera 41 to the external device 11 .

In the external device 11, after transmitting the second signal in S1010, it is determined whether or not 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 causes the display 101 to display the image captured by the camera 41, that is, the infrared image, based on the image data received by the communication unit 104 from the camera unit 33 (S1006).

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

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

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

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

In the lamp unit 31, if the elevator is in automatic operation, 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 automatic driving is being performed.

If the communication unit 112 receives the first mode signal from the monitoring device 8 while the selection unit 110 is selecting the infrared lamp 55, a determination of Yes is made in S907, and the selection unit 110 selects the visible light lamp 54 in S908. That is, when the diagnostic operation is performed in the elevator, the selector 110 selects the visible light lamp 54 . Also, when the communication unit 61 receives the first mode signal from the monitoring device 8, the determination in S909 is Yes, and the determination in S911 is Yes. In S912, the communication unit 61 transmits the image data from the camera 41 to the monitoring device 8 as diagnostic data.

In the monitoring device 8, after the communication unit 92 has transmitted 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 (diagnostic data) 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 diagnostic operation by the operation control unit 82 ends (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 unit 33. (S607). In the control device 7, when the second mode signal is received from the monitoring device 8, the operation control section 82 resumes automatic operation.

In the lamp unit 31, if 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 determination of Yes is made in S914, and the selection unit 110 selects the infrared lamp in S901. Select 55. In this example, the diagnostic data can include image data from the camera 41 . In the monitoring device 8, the operation shown in FIG. 17 may be performed separately.

FIG. 27 is a flowchart showing another operation example of the monitoring device 8. FIG. FIG. 27 shows an example of operations performed after the operations shown in FIG. 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 provided with an abnormality detection section 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 diagnostic data with a corresponding reference value. When the abnormality detection unit 93 detects an abnormality (Yes in S1201), the communication unit 92 transmits a signal indicating that an abnormality has been detected to the external device 11 (S1202).

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

Upon receiving the third mode signal from the monitoring device 8, the control device 7 starts earthquake control operation. The earthquake control operation is an 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 device 8, when the third mode signal is transmitted in S1302, the condition determination section 91 determines whether or not the recovery condition is satisfied (S1303). Recovery conditions are set in advance. For example, when the seismometer 14 detects acceleration indicating a specific level and the car 1 becomes unmanned after the earthquake control operation ends, the recovery condition is met. When the condition determination unit 91 determines that the recovery condition is satisfied (Yes in S1303), the communication unit 92 sends a fourth mode signal for setting the operation mode to the recovery mode. 33 (S1304).

When the control device 7 receives the fourth mode signal from the monitoring device 8, the recovery operation is started. That is, the operation control unit 82 performs recovery operation when the recovery condition is satisfied. In the recovery operation, recovery data necessary for determining whether the elevator can be recovered is acquired. 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 the elevator is automatically operated, 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 automatic driving is being performed.

When the communication unit 112 receives the fourth mode signal from the monitoring device 8 while the selection unit 110 is selecting the infrared lamp 55, the switching condition determination unit 113 determines that the switching condition is satisfied (Yes in S907). Accordingly, the selection unit 110 selects the visible light lamp 54 in S908. That is, when the elevator is put into recovery operation, the selector 110 selects the visible light lamp 54 . Also, when the communication unit 61 receives the fourth mode signal from the monitoring device 8, the determination in S909 is Yes, and the determination in S911 is Yes. In S912, the communication unit 61 transmits the image data from the camera 41 to the monitoring device 8 as recovery data.

In the monitoring device 8, when the communication section 92 transmits the fourth mode signal in S1304, it is determined whether or not 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 (recovery data) 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, video data from the camera 41 can 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 anomaly detection unit 93 detects an anomaly by comparing the recovery data with the corresponding reference value. When the abnormality detection unit 93 detects an abnormality (Yes in S1307), the communication unit 92 transmits a signal indicating that an abnormality has been detected to the external device 11 (S1308).

When the recovery operation ends without any abnormality being detected by the abnormality detection unit 93 (Yes in S1309), the monitoring device 8 temporarily restores the elevator (S1310). In the temporary restoration, the operation control unit 82 sets a certain limit such as a speed limit, and then operates the car 1 to sequentially respond to the registered calls. Further, the display control unit 83 causes the display 26 to display that the recovery is not complete.

If determined as Yes in S<b>1309 , the monitoring device 8 acquires post-completion video data from the camera unit 33 . The post-completion image data is data representing an image captured by the camera 41 after the recovery operation is completed. The post-finish image data is preferably visible light image data. When the monitoring device 8 acquires the post-end video data from the camera unit 33, the communication unit 92 transmits the acquired post-end video data to the external device 11 (S1311).

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

When the monitoring device 8 receives the restoration permission signal from the external device 11 (Yes in S1312), the elevator is fully restored (S1313). In this restoration, for example, the communication unit 92 transmits the second mode signal to the control device 7, the lamp unit 31, and the camera unit 33. FIG. As a result, the operation control unit 82 resumes normal operation. The display control unit 83 erases from the display 26 the indication that the recovery is not complete. Also, in the lamp unit 31 , the selection unit 110 selects the infrared lamp 55 .

In FIG. 28, an example in which the elevator is fully restored when the monitoring device 8 receives the restoration permission signal from the external device 11 has been described. This is an example. As another example, maintenance personnel visiting the site may perform a specific operation to manually restore the elevator. Further, when the seismometer 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. FIG. The operation shown in FIG. 29 differs from the operation shown in FIG. 28 in the operation when it is determined No in S1303. FIG. 29 shows an example of using the image captured by the camera 41 when the determination in S1303 is No.

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

When the post-stop video data 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 or not the recovery operation may be started in the elevator. This determination may be made, for example, by a plurality of people who have seen the video. When it is determined that recovery operation can be started in the elevator, a start signal is transmitted from the external device 11 .

In the monitoring device 8, even when the determination in S1303 is No, when the start signal is received from the external device 11 (Yes in S1315), the communication unit 92 transmits the fourth mode signal to the control device 7, the lamp unit 31, and the It is transmitted to the camera unit 33 (S1304). Upon receiving the fourth mode signal, the controller 7, the lamp unit 31 and the camera unit 33 perform operations similar to those described with reference to FIG. 29 may be performed by the control device 7 when the seismometer 14 is connected to the control device 7. FIG.

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

While the operation control unit 82 is automatically operating, the monitoring device 8 determines whether or not the maintenance mode is set (S1401). For example, the operation 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 maintenance mode. The switch 25 b 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 human 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 the elevator is automatically operated, 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 automatic driving is being performed.

When the operation mode is set to the maintenance mode while the selection unit 110 selects the infrared lamp 55, the switching condition determination unit 113 determines that the switching condition is satisfied (Yes in S907). Accordingly, the selection unit 110 selects the visible light lamp 54 in S908. Also, when the operation mode is set to the maintenance mode, a determination of Yes is made in S909, and a determination of Yes is made in S911. In S<b>912 , the communication unit 61 transmits video data from the camera 41 to the monitoring device 8 .

The video data transmitted from the communication section 61 is received by the communication section 92 in the monitoring device 8 . The human 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 human detection unit 94 detects that there is a person in the pit 3 a of the hoistway 3 based on the video data received from the camera unit 33 . The person detection section 94 detects the presence of a person on top of the car 1 based on the image data received from the camera unit of the image unit 18 .

When the person detection unit 94 detects that there is a person in the hoistway 3, the prohibition unit 95 prohibits automatic operation (S1403). For example, the movable range of the car 1 in automatic operation is wider than the movable range of the car 1 in the maintenance mode. In the example shown in FIG. 30, it is possible to prevent automatic operation from being started even though there is a person in the hoistway 3 .

When the human detector 94 detects that there is a person in the hoistway 3 , the person in the hoistway 3 may be notified according to the position of the car 1 . For example, when the human detection unit 94 detects that a person is in the hoistway 3 , the radiation control unit 111 changes the radiation mode of visible light from the visible light lamp 54 according to the position of the car 1 . For example, the radiation control unit 111 controls the visible light lamp 54 so that the blinking speed increases as the car 1 approaches the pit 3a. The radiation control section 111 may change the color of the light emitted from the visible light lamp 54 according to the position of the car 1 .

As another example, when the person detection unit 94 detects that a person is present in the hoistway 3 , the sound control unit 62 may cause the speaker 48 to output sound according to the position of the car 1 . For example, the sound control unit 62 generates a warning sound from the speaker 48 when the car 1 is placed at a position lower than a certain height. As a result, it is possible to call attention to people in the hoistway 3 .

Next, an example of implementing the above elevator system by modifying an existing elevator will be described. FIG. 31 is a flow chart showing an example of an elevator refurbishment method. The procedure from S801 to S806 in FIG. 31 is the same as the procedure from S801 to S806 in FIG.

As described above, in the elevator before renovation, light bulbs for illuminating the interior of the hoistway 3 are provided in the car 1 through the sockets 17 . Therefore, in the elevator before repair, power is not always supplied to the socket 17 . In S<b>807 , the maintenance personnel changes the setting so that power is constantly supplied to the lamp unit 31 and camera unit 33 via the socket 17 .

Next, the maintenance staff 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). Also, communication between the communication unit 112 and the access point 12 is established as necessary.

The procedure shown in S809 and the procedure shown in S810 of FIG. 31 are employed as necessary. If the car 1 is provided with a metal front flap, a step of replacing the existing metal front flap with a translucent front flap 22 may be further provided (S809). Thereby, the image of the portion covered with the front flap 22 can be photographed by the camera 41. - 特許庁

A step of newly adding the signal generation unit 75 to the portable terminal 13 of the maintenance worker may be provided (S810). This allows the selection unit 110 to select the visible light lamp 54 by operating the portable terminal 13 and display the visible light image from the camera 41 on the display 71 . Similarly, a step of newly adding the signal generator 105 to the external device 11 may be provided (S810). Thereby, the selection unit 110 can be caused to select the visible light lamp 54 by an operation from the external device 11 , and the visible light image from the camera 41 can be displayed on the display device 101 .
