The group management device 3 includes a call registration unit 30, a determination unit 31, an operation command unit 32, and a notification control unit 33. Hereinafter, the functions of the elevator system 1 will be described in detail with reference to FIGS. 3 to 5.

FIG. 3 is a flowchart showing an operation example of the monitoring device 2. As described above, the information of the image taken by the camera 13 is input to the monitoring device 2. The image taken by the camera 13 is analyzed by the image analysis unit 20 (S101). The method by which the image analysis unit 20 analyzes the image may be any method as long as it can be detected by the detection unit 21 and the detection unit 22 described later.

The detection unit 21 determines whether or not the user who is generating heat is at the landing 12 (S102). As an example, a user whose body temperature is 37.5 degrees or higher is identified as a user who has a fever. In the following, the user who is generating heat is also referred to as the "first user". The detection unit 21 detects that the first user is in the landing 12 based on the image taken by the camera 13.

The detection unit 22 determines whether or not a user other than the first user is at the landing 12 (S103). In the following, users other than users who are generating heat will also be referred to as "second users". The detection unit 22 detects that there is a second user at the landing 12 based on the image taken by the camera 13.

The signal output unit 23 outputs a signal indicating the user status of the landing 12 to the group management device 3 according to the detection result of the detection unit 21 and the detection result of the detection unit 22. For example, when the signal output unit 23 determines Yes in S103, the signal output unit 23 outputs the first signal to the group management device 3 (S104). That is, when the detection unit 21 detects that the first user is in the landing 12 and the detection unit 22 detects that the second user is in the landing 12, the signal output unit 23 outputs the first signal. ..

When the signal output unit 23 determines No in S103, it outputs a second signal to the group management device 3 (S105). That is, if the detection unit 21 detects that the first user is in the landing 12 and the detection unit 22 does not detect that the second user is in the landing 12, the signal output unit 23 outputs the second signal. Output.

If the signal output unit 23 determines No in S102, the signal output unit 23 does not output a signal to the group management device 3. That is, the signal output unit 23 does not output a signal to the group management device 3 unless the detection unit 21 detects that the first user is in the landing 12.

FIG. 4 is a flowchart showing an operation example of the group management device 3. In the group management device 3, when a registration request is input from the operation panel 14, the call registration unit 30 registers the landing call (S201). When the call from the landing 12 is registered, the determination unit 31 determines whether or not the isolation condition is satisfied for the landing 12. The isolation condition is a preset condition for isolating a user who is generating heat from other users. For example, the isolation condition is established when the detection unit 21 detects that the first user is at the landing 12 and the detection unit 22 detects that the second user is at the landing 12.

For example, when the call from the landing 12 is registered in S201, the determination unit 31 determines whether or not the first signal is received from the monitoring device 2 (S202). If the first signal is received from the monitoring device 2, the determination unit 31 determines that the isolation condition is satisfied.

When the determination unit 31 determines that the isolation condition is satisfied, the operation command unit 32 outputs a first operation command for transporting the first user to the target floor to the control device 7A. When the determination unit 31 determines that the isolation condition is satisfied, the operation command unit 32 outputs a second operation command for transporting the second user to the target floor to the control device 7B (S203). The operation command unit 32 may output the first operation command to the control device 7B according to the operation status of the A unit and the operation status of the B unit. In such a case, the operation command unit 32 outputs a second operation command to the control device 7A.

Further, when the determination unit 31 determines that the isolation condition is satisfied, the notification control unit 33 notifies the first user to get in the car 5A from the alarm 15 (S204). As a result, for example, a message such as "A person who is generating heat has been detected. Please use Unit A if you are generating heat." Is displayed on the display provided at the platform 12. When the operation command unit 32 outputs the first operation command to the control device 7B, the notification control unit 33 notifies the first user to get in the car 5B from the alarm device 15.

If the determination unit 31 determines No in S202, it determines whether or not the second signal is received from the monitoring device 2 (S205). If the second signal is received from the monitoring device 2, the operation command unit 32 outputs the first operation command for transporting the first user to the target floor to the control device 7A or the control device 7B (S206). ). In S206, the operation command unit 32 determines the output destination of the first operation command according to the operation status of the A unit and the operation status of the B unit.

On the other hand, when the determination unit 31 determines No in S205, the operation command unit 32 outputs a second operation command for transporting the second user to the target floor to the control device 7A or the control device 7B (S207). .. In S207, the operation command unit 32 determines the output destination of the second operation command according to the operation status of the A unit and the operation status of the B unit.

FIG. 5 is a flowchart showing an operation example of the control device 7 that has received the first operation command. In the following, an example in which the control device 7A receives the first operation command from the group management device 3 will be described.

When the control device 7A receives the first operation command from the group management device 3, the control device 7A stops the unmanned car 5A at the boarding floor, that is, the landing 12 (S301). The control device 7A opens and closes the door 8A when the car 5A stops at the landing 12 (S302). As a result, the first user who hears the notification of S204 gets on the car 5A and inputs the destination floor in the car 5A.

When the destination floor is input, the control device 7A performs a direct operation from the boarding floor to the destination floor (S303). That is, the control device 7A does not make the car 5A respond to other landing calls until the car 5A arrives at the destination floor. When the car 5A is stopped at the destination floor (S304), the control device 7A opens and closes the door 8A (S305). As a result, the first user gets off the car 5A.

When the door 8A is closed on the target floor, the control device 7A performs a sterilization operation for sterilizing the inside of the car 5A (S306). For example, the control device 7A replaces the air in the car 5A by operating the blower 10 in S306. As another example, the control device 7A operates the sterilization device 11 in S306. When the sterilization operation is completed, the control device 7A causes the car 5A to respond to the newly registered call.

On the other hand, in the control device 7B that receives the second operation command from the group management device 3, normal operation is performed in which the car 5B is sequentially answered to the registered call. The second user at the landing 12 moves to the destination floor in the car 5B.

In the example shown in this embodiment, if the isolation condition is satisfied when the call from the landing 12 is registered, the car 5A for the first user stops at the landing 12, and the car 5B for the second user Stop at platform 12. The first user and the second user do not need to move to the destination floor in the same car 5. Therefore, the elevator system 1 shown in the present embodiment can prevent infection such as influenza in the car 5. The elevator system 1 shown in the present embodiment is preferably applied to, for example, a hospital or the like.

A part of the functions of the monitoring device 2 may be provided in the group management device 3. A part of the functions of the group management device 3 may be provided in the monitoring device 2. Further, another device may be provided in the landing 12, and this device may be provided with a part of the function of the monitoring device 2 or a part of the function of the group management device 3.

In the present embodiment, an example in which the elevator system 1 includes a plurality of elevator devices 4 has been described. This is just an example. An example in which the elevator system 1 includes one elevator device 4 will be described below.

In the control device 7, when the registration request is input from the operation panel 14, the call registration unit 30 registers the landing call (S401). When the call from the landing 12 is registered, the determination unit 31 determines whether or not the isolation condition is satisfied for the landing 12. As described above, the isolation condition is established when the detection unit 21 detects that the first user is at the landing 12 and the detection unit 22 detects that the second user is at the landing 12.

For example, when the call from the landing 12 is registered in S401, the determination unit 31 determines whether or not the first signal is received from the monitoring device 2 (S402). If the first signal is received from the monitoring device 2, the determination unit 31 determines that the isolation condition is satisfied.

When the determination unit 31 determines that the isolation condition is satisfied, the operation control unit 34 performs a first operation for transporting the first user to the destination floor and a second operation for transporting the second user to the destination floor. Sequentially (S403). The operation control unit 34 may perform the second operation after the first operation, or may perform the first operation after the second operation. For example, the operation control unit 34 determines whether to perform the first operation first or the second operation first, depending on the operation situation when the S402 determines Yes.

Further, when the determination unit 31 determines that the isolation condition is satisfied, the notification control unit 33 notifies the notification for the first user to get in the car 5 from the alarm device 15 when the first operation is being performed. (S404). As a result, for example, a message such as "A person with fever has been detected. The person with fever will be given priority to guide to the destination floor. Others should wait for boarding." It is displayed on the provided display.

When the determination unit 31 determines No in S402, it determines whether or not the second signal is received from the monitoring device 2 (S405). If the second signal is received from the monitoring device 2, the operation control unit 34 performs the first operation for transporting the first user to the target floor (S406). On the other hand, when the determination unit 31 determines No in S405, the operation control unit 34 performs the second operation for transporting the second user to the target floor (S407).

In the first operation, the control device 7 performs the same operation as the example shown in FIG. For example, the operation control unit 34 performs a direct operation from the boarding floor to the destination floor in the first operation. After opening and closing the door 8 on the target floor in the direct operation, the operation control unit 34 performs a sterilization operation for sterilizing the inside of the car 5.
