[0009] Hereinafter, a detailed description will be given with reference to the drawings. Duplicate descriptions will be appropriately simplified or omitted. In each drawing, the same reference numerals indicate the same or corresponding parts.

[0010] Embodiment 1 Fig. 1 is a diagram showing an example of an elevator apparatus in a first embodiment. Fig. 2 is a functional block diagram of the elevator apparatus shown in Fig. 1. The elevator apparatus includes a car 1 and a counterweight 2. The car 1 moves up and down in a hoistway 3. The counterweight 2 moves up and down in the hoistway 3. The car 1 and the counterweight 2 are suspended in the hoistway 3 by a rope 4.

[0011] The rope 4 is wound around a hoisting machine 5. The car 1 is driven by the hoisting machine 5. The hoisting machine 5 is controlled by a control device 6. FIG. 1 shows an example in which the hoisting machine 5 and the control device 6 are installed in a machine room 7 above the hoistway 3. The hoisting machine 5 and the control device 6 may also be installed in the hoistway 3. When the hoisting machine 5 is installed in the hoistway 3, the hoisting machine 5 may be installed at the top of the hoistway 3 or in a pit of the hoistway 3.

[0012] The car 1 is equipped with a door 10, a motor 11, a weighing device 12, a ventilation device 13, and an operation panel 14.

[0013] The entrance to the car 1 is opened and closed by a door 10. A motor 11 drives the door 10. A weighing device 12 measures the load on the car 1. FIG. 1 shows an example in which the weighing device 12 is provided under the car floor. The weighing device 12 may be provided at the end of the rope 4. The ventilation device 13 is a device for ventilating the inside of the car 1. For example, when the ventilation device 13 operates, air from the elevator shaft 3 is taken into the inside of the car 1.

[0014] The operation panel 14 includes a display 15, a speaker 16, and buttons 17. The display 15 and the speaker 16 are examples of alarms for notifying passengers in the car 1 of information. The operation panel 14 may include only one of the display 15 or the speaker 16. The buttons 17 include a destination button for registering a destination call, an open button for opening the door 10, and a close button for closing the door 10. The buttons 17 may include other buttons.

[0015] A landing device 20 is provided at each landing 8 where the car 1 stops. The landing device 20 includes a detector 21, a landing button 22, a display 23, a display control unit 24, and a communication unit 25. Fig. 1 shows an example in which the detector 21, the landing button 22, and the display 23 are arranged on the wall of the landing 8.

[0016] The detector 21 detects the body temperature of passengers at the landing 8. The detector 21 is, for example, a thermography camera. If the landing 8 is provided in part of a passageway within a building, the detector 21 may detect the body temperature of people who stay in a specific range for a certain period of time or more in order to distinguish between passengers and passersby. The landing buttons 22 include, for example, an up button and a down button. The display control unit 24 controls the display 23.

[0017] The control device 6 includes a storage unit 31, a registration unit 32, an operation control unit 33, a mode selection unit 34, and a setting unit 35. The operation of the elevator device will be described in detail below with reference to Figs. 3 to 7 as well.

[0018] 3 is a flowchart showing an example of the operation of the hall device 20. In the hall device 20, the detector 21 detects the body temperature of a passenger at the hall 8 (S101). The display control unit 24 displays the result of detection by the detector 21 on the display 23 (S102). For example, the body temperature detected by the detector 21 is displayed as a numerical value on the display 23. An image of the hall 8 and a numerical value indicating the body temperature may be displayed superimposed on the display 23.

[0019] The hall device 20 determines whether the hall button 22 has been pressed (S103). When a passenger presses the hall button 22, S103 determines Yes. When S103 determines Yes, the communication unit 25 transmits a call registration request to the control device 6 (S104). The registration request includes information on the pressing of the hall button 22 and body temperature information indicating the body temperature of the passenger detected by the detector 21.

[0020] 3 shows an example in which the detection by the detector 21 and the display of the detection result are constantly performed. As another example, the body temperature detection by the detector 21 may be performed only for a certain period of time immediately after the landing button 22 is pressed.

[0021] FIG. 4 is a flowchart showing an example of the operation of the control device 6. The control device 6 judges 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 judges Yes in S201. When it judges Yes in S201, the registration unit 32 registers the call (S202). The call registration in S202 is performed based on the pressing information included in the registration request. For example, when a passenger presses the up button at the hall 8 on the 5th floor, a hall call for the upward direction on the 5th floor is registered in S202. An example of the hall call being registered will be described in detail below. Also, the hall call is denoted as a hall call C1.

[0022] The operation control unit 33 sequentially causes the car 1 to respond to the registered calls (S203). For example, after the passengers are let off at the first floor, the operation control unit 33 causes the car 1 to respond to the hall call C1. This causes the car 1 to move from the first floor toward the fifth floor. The control device 6 determines whether the car 1 has arrived at the hall 8 on the fifth floor (S204). When the car 1 responds to the hall call C1 and arrives at the hall 8 on the fifth floor, the result of S204 is determined as Yes. When the result of S204 is determined as Yes, the mode selection unit 34 selects an operation mode based on the detection result of the detector 21 provided at the hall 8 on the fifth floor.

[0023] A first mode, a second mode, and a third mode are set in advance as operation modes for transporting passengers by the car 1. As an example, the first mode is a normal operation mode performed for transporting passengers. The second mode and the third mode are operation modes set to suppress droplet infection of the virus. It is preferable that the third mode is a mode in which stricter measures are taken to suppress droplet infection of the virus compared to the second mode. As a more strict measure, it is considered that other measures are taken in addition to the measures taken in the second mode.

[0024] Further, the memory unit 31 stores reference values ​​T1 and T2 for body temperature. The reference values ​​T1 and T2 are set in advance. 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 a 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 selection unit 34 selects an operation mode based on the body temperature information included in the registration request.

[0025] 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. If the determination in S205 is Yes, the mode selection unit 34 selects the first mode as the operation mode (S206).

[0026] If the body temperature t is not lower than the reference value T1, the mode selection unit 34 judges No in S205. If the judgment in S205 is No, the mode selection unit 34 judges whether the body temperature t detected by the detector 21 is lower than the reference value T2 (S207). If the body temperature t is equal to or higher than the reference value T1 and lower than the reference value T2, the mode selection unit 34 judges Yes in S207. If the judgment in S207 is Yes, the mode selection unit 34 selects the second mode as the operation mode (S208).

[0027] If the body temperature t is equal to or higher than the reference value T2, the mode selection unit 34 judges No in S207. If the body temperature t is judged 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 judge whether the body temperature t is equal to or lower than the reference value T1 in S205. The mode selection unit 34 may judge whether the body temperature t is equal to or lower than the reference value T2 in S207.

[0028] 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).

[0029] Fig. 5 is a flowchart showing an example of the operation of the control device 6 when the first mode is selected. That is, Fig. 5 shows an example of the process of S210 when the determination in S205 of Fig. 4 is Yes.

[0030] For example, values ​​V1 and V2 relating to the capacity of car 1 are stored in the memory unit 31. The values ​​V1 and V2 are set in advance. For example, the value V1 is set based on the area of ​​the car floor. The value V2 is smaller than the value V1. As an example, the value V2 is set to 1 / 2 the value V1.

[0031] The setting unit 35 sets the capacity of car 1. When it is determined as Yes in S205 of Fig. 4, the setting unit 35 sets the capacity of car 1 to a value V1 (S301). In addition, the operation control unit 33 sets the air volume of the ventilation device 13 to "weak" (S302). If it is winter, the operation control unit 33 may turn off the ventilation device 13 in S302.

[0032] When car 1, which responded to hall call C1 in S204 of FIG. 4, stops at hall 8 on the 5th floor, a passenger gets on car 1. Thereafter, the passenger presses button 17 in car 1, and a destination call is registered. For example, when a passenger presses button 17 for the 10th floor, destination call C2 for the 10th floor is registered. The operation control unit 33 causes car 1 to respond to destination call C2 (S303). As a result, car 1 moves toward hall 8 on the 10th floor.

[0033] Fig. 6 is a flowchart showing an example of the operation of the control device 6 when the second mode is selected. That is, Fig. 6 shows an example of the process of S210 when the determination in S207 of Fig. 4 is Yes.

[0034] If S207 in FIG. 4 is judged as Yes, the setting unit 35 sets the capacity of car 1 to value V1 (S401). Furthermore, the operation control unit 33 sets the air volume of the ventilation device 13 to "high" (S402). In winter, the operation control unit 33 may operate the ventilation device 13 at the air volume of "low" in S402. That is, the operation control unit 33 sets the ventilation volume by the ventilation device 13 to be larger in S402 than the ventilation volume in S302. The process shown in S403 in FIG. 6 is similar to the process shown in S303 in FIG. 5.

[0035] Fig. 7 is a flowchart showing an example of the operation of the control device 6 when the third mode is selected. That is, Fig. 7 shows an example of the process of S210 when the determination in S207 of Fig. 4 is No.

[0036] 4 is determined to be No, the setting unit 35 sets the capacity of the car 1 to the value V2 (S501). This prevents passengers from crowding in the car 1. As an example, the determination of whether the car 1 is full or not is made based on the live load measured by the weighing device 12.

[0037] The process shown in S502 of Fig. 7 is similar to the process shown in S402 of Fig. 6. The process shown in S502 of Fig. 7 may be similar to the process shown in S302 of Fig. 5. The process shown in S503 of Fig. 7 is similar to the process shown in S303 of Fig. 5. However, in the example shown in Fig. 7, the determination of whether car 1 is full is made based on value V2.

[0038] The operation control unit 33 may stop the car 1 at the landing 8 on the 10th floor in response to the destination call C2, and then perform ventilation before closing the door 10. For example, the operation control unit 33 operates the ventilation device 13 for a certain period of time with the door 10 open (S504).

[0039] In this elevator system, an appropriate operation mode is selected according to the body temperature of the passenger detected by the detector 21. In this elevator system, even if a passenger has a high body temperature, the passenger is not denied entry. With this elevator system, appropriate control can be performed according to the passenger's body temperature.

[0040] In the present embodiment, an example has been described in which the hall button 22 includes an up button and a down button. The hall button 22 may include a plurality of destination buttons.

[0041] Fig. 8 is a flow chart showing another example of the operation of the control device 6. Fig. 8 shows an example of the operation performed between S203 and S204 in Fig. 4. When the operation shown in Fig. 8 is performed, the control device 6 is further provided with an alarm control unit 36. The alarm control unit 36 ​​controls an alarm provided in the car 1. In addition, a reference value T3 for body temperature is further stored in the memory unit 31. The reference value T3 is a temperature equal to or higher than the reference value T1. It is preferable that the reference value T3 is a temperature higher than the reference value T2. The reference value T3 may be the same temperature as the reference value T2.

[0042] When a hall call C1 is registered based on a certain registration request as in the above example, the operation control unit 33 causes the car 1 to respond to the hall call C1 after dropping off passengers at the first floor (S203). This causes the car 1 to move from the first floor to the fifth floor. At this time, the control device 6 determines whether or not an alert needs to be issued to the inside of the car 1 based on the body temperature information included in the registration request.

[0043] For example, the control device 6 judges 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 detector 21 installed at the landing 8 on the 5th floor detects a body temperature t higher than the reference value T3, the result of S601 is Yes. If the result of S601 is Yes, the notification control unit 36 ​​causes the alarm to notify that a passenger with a high body temperature will board on the 5th floor (S602).

[0044] The notification of S602 is made before car 1 stops at platform 8 on the 5th floor. If a passenger in car 1 who hears this notification does not wish to ride in the same car 1 as a passenger with a high body temperature, he or she may get off car 1 at the 5th floor. The passenger in car 1 may press button 17 for the 4th floor and get off car 1 at the 4th floor.

[0045] Such an elevator system is useful in places such as hospitals or nursing homes where priority should be given to passengers with high fevers.
