Buttons 17 include a destination button for registering a destination call, an open button for opening door 10 and a close button for closing door 10 . Other buttons may be included in button 17 .

A landing device 20 is provided at each landing 8 where the car 1 stops. The hall device 20 includes a detector 21 , a hall button 22 , a display 23 , a display control section 24 and a communication section 25 . FIG. 1 shows an example in which a detector 21 , a hall button 22 and a display 23 are arranged on the wall of the hall 8 .

A detector 21 detects the body temperature of passengers at the landing 8 . Detector 21 is, for example, a thermography camera. When the landing 8 is provided in a part of the passage in the building, the detector 21 detects the body temperature of a person who stays in a specific area for a certain period of time or more in order to distinguish between passengers and passers-by. Also good. The hall buttons 22 include, for example, an up button and a down button. The display control unit 24 controls the display device 23 .

The control device 6 includes a storage section 31 , a registration section 32 , an operation control section 33 , a mode selection section 34 and a setting section 35 . The operation of the elevator system will be described in detail below with reference to FIGS. 3 to 7 as well.

FIG. 3 is a flowchart showing an operation example of the hall device 20. As shown in FIG. In the hall device 20, the body temperature of the passengers in the hall 8 is detected by the detector 21 (S101). The display control unit 24 displays the result detected by the detector 21 on the display 23 (S102). For example, the body temperature detected by the detector 21 is displayed numerically on the display 23 . The display 23 may superimpose an image of the boarding hall 8 and a numerical value representing the body temperature on the display.

In the hall device 20, it is determined whether or not the hall button 22 has been pushed (S103). When the passenger presses the hall button 22, it is determined as Yes in S103. If determined as Yes in S103, the communication unit 25 transmits a call registration request to the control device 6 (S104). The registration request includes information on pressing the hall button 22 and body temperature information indicating the body temperature of the passenger detected by the detector 21 .

FIG. 3 shows an example in which detection by the detector 21 and display of the detection result are always performed. As another example, detection of body temperature by detector 21 may be performed only for a certain period of time immediately after hall button 22 is pushed.

FIG. 4 is a flow chart showing an operation example of the control device 6 . The control device 6 determines whether or not a call registration request has been received from the hall device 20 (S201). When the control device 6 receives the registration request transmitted from the hall device 20 in S104, it is determined as Yes in S201. If determined as Yes in S201, the registration unit 32 registers the call (S202). The registration of the call in S202 is performed based on the pressing information included in the registration request. For example, when a passenger presses the up button at hall 8 on the 5th floor, in S202 an upward hall call for the 5th floor is registered. An example in which the hall call is registered will be described in detail below. In addition, the hall call is written as hall call C1.

The operation control unit 33 sequentially causes the car 1 to respond to the registered calls (S203). For example, the operation control unit 33 causes the car 1 to respond to the hall call C1 after the passengers get off on the first floor. As a result, the car 1 moves from the first floor to the fifth floor. The control device 6 determines whether or not the car 1 has arrived at the landing 8 on the fifth floor (S204). When the car 1 arrives at the fifth-floor hall 8 in response to the hall call C1, S204 is determined to be Yes. If it is determined as Yes in S204, the mode selection unit 34 selects the operation mode based on the detection result of the detector 21 provided in the hall 8 on the fifth floor.

A first mode, a second mode, and a third mode are set in advance as operation modes for carrying passengers by the car 1 . As an example, the first mode is a normal operating mode for carrying passengers. The second mode and the third mode are operation modes set to suppress virus droplet infection. The third mode is preferably a mode in which stricter measures are taken to suppress virus droplet infection than in the second mode. As a more stringent countermeasure, it is conceivable that other countermeasures are additionally taken in addition to the countermeasures taken in the second mode.

Further, the storage unit 31 stores reference values T1 and T2 for body temperature. Reference values T1 and T2 are preset. The reference value T2 is a temperature higher than the reference value T1. As described above, the registration request received from the hall device 20 includes body temperature information. When the hall call C1 is registered based on a certain registration request and the car 1 stops at the hall 8 in response to the hall call C1, the mode selector 34 selects the operation mode based on the body temperature information included in the registration request. select.

For example, the mode selection unit 34 determines whether the body temperature t detected by the detector 21 is lower than the reference value T1 based on the body temperature information included in the registration request (S205). If the body temperature t is lower than the reference value T1, the mode selection unit 34 determines Yes in S205. When it is determined as Yes in S205, the mode selection unit 34 selects the first mode as the operation mode (S206).

If the body temperature t is not lower than the reference value T1, the mode selection unit 34 determines No in S205. When it is determined No in S205, the mode selection unit 34 determines whether or not the body temperature t detected by the detector 21 is lower than the reference value T2 (S207). If the body temperature t is greater than or equal to the reference value T1 and lower than the reference value T2, the mode selection unit 34 determines Yes in S207. When it is determined as Yes in S207, the mode selection unit 34 selects the second mode as the operation mode (S208).

If the body temperature t is equal to or higher than the reference value T2, the mode selection unit 34 determines No in S207. When it is determined No in S207, the mode selection unit 34 selects the third mode as the operation mode (S209). Note that the mode selection unit 34 may determine whether or not the body temperature t is equal to or lower than the reference value T1 in S205. The mode selection unit 34 may determine whether or not the body temperature t is equal to or lower than the reference value T2 in S207.

When the operation mode is selected by the mode selection unit 34, the operation control unit 33 performs control in the operation mode selected by the mode selection unit 34 (S210).

FIG. 5 is a flow chart showing an operation example of the control device 6 when the first mode is selected. That is, FIG. 5 shows a processing example of S210 when it is determined as Yes in S205 of FIG.

For example, the storage unit 31 stores values V1 and V2 regarding the capacity of the car 1 . The values V1 and V2 are preset. For example, the value V1 is set based on the area of the car floor. The value V2 is less than the value V1. As an example, the value V2 is set to 1/2 the value V1.

The setting unit 35 sets the capacity of the car 1 . If it is determined as Yes in S205 of FIG. 4, the setting unit 35 sets the capacity of car 1 to the value V1 (S301). Further, the operation control unit 33 sets the air volume of the ventilation device 13 to "low" (S302). In winter, the operation control unit 33 may turn off the ventilator 13 in S302.

When the car 1 that has responded to the hall call C1 in S204 of FIG. A destination call is then registered by the passenger pressing button 17 in car 1 . For example, when the passenger presses the button 17 for the 10th floor, the destination call C2 for the 10th floor is registered. The operation control unit 33 causes the car 1 to respond to the destination call C2 (S303). As a result, the car 1 moves toward the landing 8 on the tenth floor.

FIG. 6 is a flow chart showing an operation example of the control device 6 when the second mode is selected. That is, FIG. 6 shows a processing example of S210 when it is determined as Yes in S207 of FIG.

If it is determined as Yes in S207 of FIG. 4, the setting unit 35 sets the capacity of car 1 to the value V1 (S401). Further, the operation control unit 33 sets the air volume of the ventilation device 13 to "strong" (S402). In winter, the operation control unit 33 may operate the ventilation device 13 with the air volume of "low" in S402. That is, in S402, the operation control unit 33 makes the ventilation volume by the ventilator 13 larger than the ventilation volume in S302. The processing shown in S403 of FIG. 6 is the same as the processing shown in S303 of FIG.

FIG. 7 is a flow chart showing an operation example of the control device 6 when the third mode is selected. That is, FIG. 7 shows a processing example of S210 when it is determined as No in S207 of FIG.

When it is determined No in S207 of FIG. 4, the setting unit 35 sets the capacity of car 1 to the value V2 (S501). This prevents passengers from crowding together in the car 1 . As an example, the determination of whether or not the car 1 is full is made based on the load measured by the weighing device 12 .

The processing shown in S502 of FIG. 7 is the same as the processing shown in S402 of FIG. The processing shown in S502 of FIG. 7 may be the same as the processing shown in S302 of FIG. The processing shown in S503 of FIG. 7 is the same as the processing shown in S303 of FIG. However, in the example shown in FIG. 7, whether or not the car 1 is full is determined based on the value V2.

After stopping the car 1 at the hall 8 on the 10th floor in response to the destination call C2, the operation control unit 33 may perform ventilation before closing the door 10 . For example, the operation control unit 33 operates the ventilator 13 for a certain period of time with the door 10 open (S504).

In this elevator system, an appropriate operation mode is selected according to the passenger's body temperature detected by the detector 21 . In this elevator system, even if there is a passenger with a high body temperature, the passenger is not refused to use the elevator. With this elevator system, appropriate control can be performed according to the body temperature of passengers.

In the present embodiment, an example in which the landing buttons 22 include the up button and the down button has been described. The hall button 22 may include a plurality of destination buttons.

FIG. 8 is a flow chart showing another operation example of the control device 6 . FIG. 8 shows an example of operations performed between S203 and S204 of FIG. When the operation shown in FIG. 8 is performed, the control device 6 is further provided with a notification control section 36 . The notification control unit 36 controls the notification device provided in the car 1 . Further, the storage unit 31 further stores a reference value T3 for body temperature. The reference value T3 is a temperature equal to or higher than the reference value T1. The reference value T3 is preferably a temperature higher than the reference value T2. The reference value T3 may be the same temperature as the reference value T2.

When the hall call C1 is registered based on a registration request as in the above example, the operation control unit 33 causes the car 1 to respond to the hall call C1 after the passengers get off on the first floor (S203). As a result, the car 1 moves from the first floor to the fifth floor. At this time, the controller 6 determines whether notification to the car 1 is necessary based on the body temperature information included in the registration request.

For example, the control device 6 determines whether the body temperature t detected by the detector 21 is higher than the reference value T3 based on the body temperature information included in the registration request (S601). If the body temperature t higher than the reference value T3 is detected by the detector 21 provided in the hall 8 on the fifth floor, the determination in S601 is Yes. If it is determined as Yes in S601, the notification control unit 36 notifies from the notification device that the passenger with a high body temperature will board on the 5th floor (S602).

The notification of S602 is made before the car 1 stops at the hall 8 on the fifth floor. Passengers in car 1 who have heard this information may get off car 1 on the fifth floor if they do not want to ride in car 1 with passengers with high body temperature. Passengers in car 1 may press the 4th floor button 17 and exit car 1 on the 4th floor.

Such an elevator system is effective in hospitals, nursing homes, etc., where priority is given to passengers with a high fever.
