The present invention will be described with reference to the accompanying drawings. The overlapping description will be simplified or omitted as appropriate. In each figure, the same reference numerals indicate the same or corresponding parts.

Embodiment 1 FIG.
1 is a diagram showing a configuration example of an elevator system according to Embodiment 1 of the present invention. FIG. 1 shows an example in which an elevator system is provided in a private house 1. The building provided with the elevator system is not limited to the private house 1. For example, the elevator system may be provided in a relatively large building for commercial use. The elevator system includes, for example, a car 2, a control device 3, a communication device 4, and an operation terminal 5.

Car 2 moves up and down the hoistway. The control device 3 controls the operation of the elevator. For example, the control device 3 controls the operation of the car 2. That is, the vertical movement of the car 2 is controlled by the control device 3. The communication device 4 is connected to the control device 3.

The operation terminal 5 is a terminal for a person on the car 2 to operate. The operation terminal 5 is provided in the car 2. The operation terminal 5 includes a display 6 and an input device 7, for example. FIG. 1 shows an example in which the operation terminal 5 includes a touch panel type input device 7. The input device 7 may include a plurality of buttons.

The house 1 is provided with an access point 8 for performing wireless communication. The access point 8 need not be dedicated to the elevator system. For example, a device provided in the house 1 is connected to an external network 9 via the access point 8. The network 9 is, for example, an internet line.

Signal transmission / reception between the operation terminal 5 and the communication device 4 is performed via the access point 8. For example, a person on the car 2 inputs a destination call from the input device 7. The operation terminal 5 transmits a call signal input from the input device 7 to the communication device 4 via the access point 8. The communication device 4 transmits the received call signal to the control device 3. The control device 3 controls the driving device (not shown) based on the call signal received from the communication device 4 to move the car 2.

Since the car 2 moves on the hoistway, the communication between the car 2 and the access point 8 is performed wirelessly. Since the relative position between the communication device 4 and the access point 8 does not change, the communication between the communication device 4 and the access point 8 may be performed by wire.

The communication device 4 receives a control signal from the control device 3. The communication device 4 transmits the control signal received from the control device 3 to the car 2 and the operation terminal 5 via the access point 8. The car 2 performs necessary operations based on the control signal received from the communication device 4. For example, the car 2 controls the lighting based on the control signal received from the communication device 4. The operation terminal 5 performs a necessary operation based on the control signal received from the communication device 4. For example, the operation terminal 5 controls the display on the display 6 based on the control signal received from the communication device 4.

The communication device 4 has a function of monitoring an elevator, for example. For example, the communication device 4 detects that a person is trapped in the car 2. When the communication device 4 detects that a person is confined in the car 2, the communication device 4 transmits a confinement signal to the operation terminal 5 via the access point 8. When receiving the confinement signal from the communication device 4, the operation terminal 5 performs a necessary operation based on the received confinement signal. For example, the operation terminal 5 controls the display on the display 6 based on the confinement signal received from the communication device 4. Below, with reference also to FIG. 2, the example of the operation | movement which this elevator system performs is demonstrated. FIG. 2 is a flowchart showing an operation example of the elevator system according to Embodiment 1 of the present invention. FIG. 2 shows an operation flow when confinement occurs.

The communication device 4 detects that a person is trapped in the car 2 when a certain condition is satisfied (Yes in S101). When detecting that a person is trapped in the car 2, the communication device 4 notifies the management center 10 that manages the elevator system (S102). The notification from the communication device 4 to the management center 10 may be performed via the access point 8 or via the dedicated communication line 11. Upon receiving the report, the management center 10 selects a rescuer to be dispatched to the house 1 and calls through a video phone or the like as necessary. Note that the call by the video phone or the like is performed when the operation terminal 5 is provided with the camera 12.

Also, in the management center 10, when a rescuer dispatched to the house 1 is selected, information regarding the rescuer is transmitted to the operation terminal 5. The information regarding the rescuer may be transmitted via the communication line 11 or via the network 9. However, the operation terminal 5 receives the information from the access point 8. When receiving information related to the rescuer via the access point 8 (Yes in S103), the operation terminal 5 displays information related to the estimated arrival time of the rescuer on the display 6 (S104). For example, a content such as “The rescuer arrives in about 15 minutes” is displayed on the display 6. The operation terminal 5 may display information on the current position of the rescuer on the display device 6. In addition, you may transmit the information regarding a rescuer from the terminal which a rescuer himself owns.

When the communication device 4 detects that a person is confined in the car 2 (Yes in S101), the communication device 4 transmits a confinement signal to the operation terminal 5 via the access point 8 (S105). When receiving the confinement signal, the operation terminal 5 activates the rescue program (S106). The rescue program is a program for contacting the outside via the access point 8. The rescue program is stored in the operation terminal 5 and preset to be activated by receiving a confinement signal from the communication device 4. In addition, it is desirable that the external communication by the rescue program is performed without using the communication device 4.

In the operation terminal 5, an e-mail address is registered in advance as a contact address when confinement occurs. For example, the mail address of the family mobile terminal 13 is registered in the operation terminal 5 as a contact address. The mobile terminal 13 is a smartphone, for example. When the rescue program is activated, the operation terminal 5 transmits a mail for notifying that the confinement has occurred with respect to the mail address registered in advance (S107). At this time, the operation terminal 5 may display on the display 6 that the mail is transmitted to the registered mail address and that the mail is transmitted. The mobile terminal 13 that has received the mail from the operation terminal 5 is, for example, “An elevator has been trapped. Is it possible to go to the home? Select from the following options and reply. 1) Possible, 2 ) Impossible "is displayed.

When the operation terminal 5 transmits a mail to the device such as the mobile terminal 13 in S107, the operation terminal 5 determines whether a reply is received from the device (S108). When receiving a reply from the device that is the destination of the mail, the operation terminal 5 displays information on the position of the device that has received the reply on the display 6 (S109). The display of information related to the position can be easily realized by receiving position information by GPS from a device such as the mobile terminal 13. The operation terminal 5 may cause the display 6 to display information related to the estimated arrival time of the owner of the device that has received the reply. For example, a content such as “Family A arrives in about 15 minutes” is displayed on the display 6.

FIG. 1 shows an example in which a door 15 having an electric lock 14 is installed in a house 1. The door 15 is a door for a person to enter the house 1. The electric lock 14 is normally locked so that the door 15 does not open. The electric lock 14 is unlocked when the unlocking operation is performed on the operation panel 16 provided in front of the entrance of the house 1 or the like. The operation panel 16 includes an interphone, for example. Locking and unlocking of the electric lock 14 is controlled by the control device 17.

The operation terminal 5 communicates with the control device 17 via the access point 8. For example, when a rescuer who has received a notification of confinement arrives at the house 1 and presses the intercom on the operation panel 16 (Yes in S110), an image captured by the intercom camera is displayed on the display 6 of the operation terminal 5. (S111). The person trapped in the car 2 can see that the person who operated the interphone is a rescuer by looking at the display 6 of the operation terminal 5. For example, the person trapped in the car 2 transmits an unlocking signal for unlocking the electric lock 14 from the operation terminal 5 (S112). An unlock signal from the operation terminal 5 is transmitted to the control device 17 via the access point 8. When receiving the unlock signal from the operation terminal 5, the control device 17 unlocks the electric lock 14. Thereby, a rescuer enters the house 1 and performs a rescue operation.

In the elevator system shown in the first embodiment, the operation terminal 5 communicates with the communication device 4 via the access point 8 provided in the house 1. For this reason, it is not necessary to connect the conventionally used communication cable to the operation terminal 5. The configuration and labor for connecting the communication cable to the operation terminal 5 are eliminated, and the system can be provided at low cost.

In the example shown in the first embodiment, various operations can be performed without connecting any communication cable between the car 2 and the control device 3. If it is not necessary to connect a communication cable between the car 2 and the control device 3, the installation work of the car 2 and the like can be greatly simplified.

In the example shown in the first embodiment, a general-purpose device such as a tablet PC can be used as the operation terminal 5. For example, the user can purchase his / her favorite tablet PC and use the purchased PC as the operation terminal 5. It is also possible to remove the operation terminal 5 from the car 2 and use it.

When using a tablet PC or the like purchased by the user as the operation terminal 5, it is necessary to install a program for performing various operations on the operation terminal 5. For example, a call registration program necessary for the operation terminal 5 to transmit a call signal to the communication device 4 must be installed in the operation terminal 5. In preparation for such a case, for example, a call registration program or the like is stored in advance in the storage device 18 of the management center 10. The user may connect the operation terminal 5 to the management center 10 via the access point 8 and download a call registration program or the like from the storage device 18. By adopting such a configuration, the price of the system can be further reduced. The place where the call registration program is prepared in advance is not limited to the management center 10.
