  The control device 6 includes a confinement detection unit 14. The confinement detection unit 14 detects that a person is confined in the car 1. The condition for the confinement detection unit 14 to detect confinement may be any condition. For example, the confinement detection unit 14 detects that a person is confined in the car 1 when the car 1 stops between floors and a car call is registered. The confinement detection unit 14 detects that a person is confined in the car 1 when the car 1 is stopped between the floors and a load exceeding a reference value is detected by a weighing device (not shown) of the car 1. You may do it. The confinement detection unit 14 may detect that a person is confined in the car 1 when the call button 11a of the intercom 11 is pressed.

  The control device 6 includes a communication control unit 15. For example, an access point is provided in an elevator apparatus. FIG. 1 shows an example in which an elevator apparatus includes four access points 16a to 16d. The access points 16a to 16d are installed to perform wireless communication with the wireless terminal 17 in the car 1. The wireless terminal 17 is owned by the user. For example, the wireless terminal 17 is a smartphone owned by the user. The wireless terminal 17 may be another mobile terminal owned by the user. The car 1 need not have a dedicated wireless terminal.

  For example, the access point 16 a is provided in the car 1. In the example shown in FIG. 1, the access point 16 a is arranged on the car 1. The access point 16a may be arranged inside the car 1. The access point 16a is connected to the control device 6 via the control cable 8. The access point 16b is provided at the landing 18 where the car 1 stops. In the example shown in FIG. 1, the access point 16b is arranged at the hall 18 on the lobby floor. The access point 16b may be arranged at a plurality of halls 18 where the car 1 stops. You may arrange | position the access point 16b in all the platforms 18 where the car 1 stops. The access point 16 b that is not provided in the car 1 is connected to the control device 6 by wire without going through the control cable 8. The same applies to access points 16c and 16d described later.

  The access point 16 c is disposed in the hoistway 3. The access point 16c is provided on a fixed body of the hoistway 3, for example. In the example shown in FIG. 1, the access point 16 c is arranged at the top of the hoistway 3. The access point 16c may be arranged in the pit of the hoistway 3. The access point 16d is disposed in the machine room 7. In the example shown in FIG. 1, the access point 16 d is connected to the control device 6 by wire. The access point 16d may be built in the control device 6. The communication control unit 15 controls the access points 16a to 16d. For example, the communication control unit 15 controls on and off of the access points 16a to 16d.

  FIG. 1 shows an example in which access points are installed at a plurality of locations. The number of access points and installation locations are not limited to the example shown in FIG. For example, an access point may be installed at a management center in the same building.

  The communication method used when the access points 16a to 16d perform wireless communication with the wireless terminal 17 may be any communication method. For example, all of the access points 16a to 16d may perform wireless communication with the wireless terminal 17 using the same communication method. All of the access points 16a to 16d may perform wireless communication with the wireless terminal 17 using different communication methods. Only some of the access points 16a to 16d may perform wireless communication with the wireless terminal 17 using the same communication method. For example, Bluetooth (registered trademark) may be adopted as the communication method. Further, Wi-Fi (registered trademark) may be adopted as a communication method. Another wireless LAN may be adopted as a communication method.

  A plurality of access points with different communication methods may be installed in the same place. For example, an access point that is wirelessly connected to the wireless terminal 17 by the first communication method and an access point that is wirelessly connected to the wireless terminal 17 by the second communication method may be installed on the car 1. The second communication method is a communication method different from the first communication method. Furthermore, an access point that is wirelessly connected to the wireless terminal 17 by the third communication method and an access point that is wirelessly connected to the wireless terminal 17 by the fourth communication method may be installed in the hoistway 3. The third communication method is a communication method different from the first communication method and the second communication method. The fourth communication method is a communication method different from the first communication method, the second communication method, and the third communication method.

  Next, the operation of the elevator apparatus will be described with reference to FIG. FIG. 3 is a flowchart showing an operation example of the elevator apparatus according to Embodiment 1 of the present invention.

  While the normal operation is performed, the communication control unit 15 turns off the access points 16a to 16d (S101). The normal operation is an operation in which the car 1 sequentially responds to the generated calls. During normal operation, the user cannot wirelessly connect his / her wireless terminal 17 to the access points 16a to 16d.

  During normal operation, the confinement detection unit 14 determines whether a person is confined in the car 1 (S102). For example, when the car 1 stops between the floors and the user in the car 1 presses the call button 11a, the confinement detection unit 14 detects that a person is confined in the car 1. When confinement is detected in S102, the communication control unit 15 turns on the access points 16a to 16d (S103). That is, the communication control unit 15 enables wireless communication between the wireless terminal 17 in the car 1 and the access points 16a to 16d. As shown in S101, the communication control unit 15 performs wireless communication between the wireless terminal 17 and the access points 16a to 16d unless the confinement detection unit 14 detects that a person is confined in the car 1. Is prohibited. When turning on the access points 16a to 16d, the communication control unit 15 determines whether a wireless communication line has been established (S104).

  If the wireless communication line cannot be detected in S104, the display control unit 13 causes the display device 10 to display guidance for prompting the person in the car 1 to contact the outside. For example, the display control unit 13 causes the display device 10 to display a telephone number leading to a monitoring center or the like (S105). The display control unit 13 may cause the display device 10 to display a mail address that leads to a monitoring center or the like.

  When the communication control unit 15 detects a wireless communication line, the display control unit 13 causes the display device 10 to display guidance for wirelessly connecting the wireless terminal 17 to the access points 16a to 16d (S106). For example, the display control unit 13 displays the connection name of the wireless communication line detected by the communication control unit 15 on the display device 10 and prompts the user to establish a wireless connection. The display control unit 13 may display a partial connection name of the wireless communication line detected by the communication control unit 15 on the display device 10 to prompt the user to make a wireless connection. For example, when detecting the wireless communication line in S104, the communication control unit 15 selects one or a plurality of wireless communication lines from the detected wireless communication lines based on a preset selection criterion. For example, the communication control unit 15 selects a wireless communication line having a certain radio wave intensity. The display control unit 13 displays the connection name of the wireless communication line selected by the communication control unit 15 on the display device 10.

  As another example, consider a case where a plurality of access points with different communication methods are provided. For example, consider a case where a plurality of access points of the first communication method, a plurality of access points of the second communication method, and a plurality of access points of the third communication method are provided. In such a case, when the communication control unit 15 detects a wireless communication line in S104, the communication control unit 15 selects one or more wireless communication lines for each communication method from the detected wireless communication lines based on a preset selection criterion. To do. For example, the communication control unit 15 selects the one having the highest radio field intensity among the same communication methods.

The communication control unit 15 may select one having the highest access point priority order in the same communication method. The communication control unit 15 may select, for each communication method, one having the highest access point priority from those having a certain radio field intensity. In such a case, for example, the priority order is set in advance for the access point based on the installation location. For example, the priority order is set as follows.
Priority 1: Wireless communication circuit using access points installed in car 1 Priority 2: Wireless communication circuit using access points installed in hoistway 3 Priority 3: Access points installed in controller 6 Wireless communication circuit priority order 4: Wireless communication circuit priority order using an access point held by a building manager 5: Other general access-free wireless communication circuits

  The display control unit 13 causes the display device 10 to display guidance for connecting to the wireless communication line selected by the communication control unit 15. For example, the display control unit 13 displays the connection name of the wireless communication line selected by the communication control unit 15 on the display device 10 and prompts the user to establish a wireless connection. For example, the display control unit 13 may display “EV-B” if the connection with the first communication method is desired, or “EV-W” when the connection with the second communication method is desired. "If you wish to connect with the third communication method, please set" EV-L "with your wireless terminal". When the wireless terminal 17 is wirelessly connected to any access point, communication between the wireless terminal 17 and an external monitoring center or the like is started with text and image data (S107).

  When communication is started between the wireless terminal 17 and an external monitoring center or the like, the communication control unit 15 determines whether or not the line is disconnected during communication (S108 and S109). When the line is disconnected during communication, the communication control unit 15 returns to the process of S104 and again determines whether or not the wireless communication line has been established.

  If it is an elevator apparatus which has the said structure, even if it is a case where a user, especially a hearing-impaired person is confine | sealed in the cage | basket | car 1, the person can perform two-way communication with the exterior easily using his own radio terminal. be able to. In this elevator apparatus, the access point is controlled by the communication control unit 15. The communication control unit 15 disables wireless communication between the wireless terminal 17 and the access point unless the confinement detection unit 14 detects that a person is confined in the car 1. Further, when the confinement detection unit 14 detects that a person is confined in the car 1, the communication control unit 15 enables wireless communication between the wireless terminal 17 and the access point. For this reason, while ensuring a certain level of security, the user's wireless terminal 17 can perform bidirectional communication with the outside without using a dedicated wireless terminal when confinement occurs.

  Further, in this elevator apparatus, when the confinement detection unit 14 detects that a person is confined in the car 1, guidance for connecting the wireless terminal 17 to the access point wirelessly is displayed on the display device 10. For this reason, even if the person confined in the car 1 is a hearing impaired person, the person can easily connect the wireless terminal 17 to the access point by looking at the guidance displayed on the display device 10.

  FIG. 4 is a flowchart showing another example of operation of the elevator apparatus according to Embodiment 1 of the present invention. The processes shown in S201 and S202 of FIG. 4 are the same as the processes shown in S101 and S102 of FIG.

  When the confinement detection unit 14 detects that a person is confined in the car 1 in S202, the display control unit 13 displays options for a method for contacting the outside on the display device 10 (S203). For example, the display control unit 13 causes the display device 10 to display guidance for inputting from the input device 12 whether to communicate with the outside through the intercom 11 or through the wireless terminal 17 of the display control unit 13. The user who has viewed the display on the display device 10 selects one of the options by operating the input device 12 (S204).

  When the control device 6 inputs from the input device 12 that communication with the outside is made through the interphone 11, voice communication by the interphone 11 is started (S205). In addition, in the control device 6, if no input is made from the input device 12 even after a predetermined time has elapsed since the display on the display device 10 in S203, voice communication by the interphone 11 is started (S205).

  On the other hand, when the input device 12 inputs that communication with the outside is made through the wireless terminal 17, the communication control unit 15 turns on the access points 16a to 16d (S206). That is, the communication control unit 15 enables wireless communication between the wireless terminal 17 in the car 1 and the access points 16a to 16d. Note that, as shown in S201, the communication control unit 15 performs wireless communication between the wireless terminal 17 and the access points 16a to 16d unless the confinement detection unit 14 detects that a person is confined in the car 1. Is prohibited. Further, even if the confinement is detected in S202, if the communication control unit 15 does not input from the input device 12 that the communication with the outside is made through the wireless terminal 17, the wireless communication between the wireless terminal 17 and the access points 16a to 16d. Leave communication disabled. When turning on the access points 16a to 16d, the communication control unit 15 determines whether a wireless communication line has been established (S207).

  The processes shown in S206 to S212 in FIG. 4 are the same as the processes shown in S103 to S109 in FIG. For this reason, detailed description is omitted.

  Even if the operation example shown in FIG. 4 is adopted, the same effect as described above can be expected. In the operation example shown in FIG. 4, the user already understands that when the access point is turned on in S <b> 206, the user communicates with the outside through the wireless terminal 17. For this reason, the process for displaying the guidance for prompting the wireless connection on the display device 10 in S209 is not essential. However, by performing the process shown in S209, the user can set the connection of the wireless terminal 17 more smoothly.

  Each part shown to the codes | symbols 13-15 shows the function which the control apparatus 6 has.
