A passenger determination unit 112 detects a passenger in the car 111 . More specifically, the passenger determination unit 112 detects new passengers and fullness in the current car 111 . In these new passenger detection and occupancy detection, determination is made based on the load value input from the load detection unit 121 to the elevator car 110 . The load value input from the load detector 121 to the elevator car 110 is, for example, the ratio of the current load of the car 111 to the rated load of the elevator car 110 .
New passenger detection is performed by comparing the difference value between the maximum and minimum load values while the door is open and a preset new passenger determination threshold value. For example, when the maximum value of the load value input from the load detection unit 121 to the elevator car 111 while the door is open is 40% and the minimum value is 20%, the difference between the maximum value and the minimum value of the load value while the door is open The value is 20%, and when the new passenger determination threshold is 8%, the passenger determination unit detects a new passenger.
In addition, occupancy detection is performed by comparing the load value while the door is open with a occupancy determination threshold value. For example, when the load value input from the load detection unit 121 to the elevator car 111 while the door is open is 40%, and the fullness determination threshold is 80%, the passenger determination unit 112 does not detect fullness.

The passenger determination unit 112 may perform determination using a value other than the load value.

[Cleaning operation processing unit 118]
The cleaning operation processing unit 118 is for controlling the cleaning operation inside the car 111 (hereinafter also referred to as "car cleaning operation"), and has a cleaning operation control unit 118a and a cleaning operation command unit 118b.
The clean operation control unit 118a holds information about control of each clean operation, and performs start condition determination, control, and end condition determination of the clean operation. For example, the condition for activating the clean operation is that the elevator car 110 has completed responding to the service requests at the landing and in the car, and that a certain period of time has elapsed since there were no other requests. Here, when the activation condition is satisfied, the cleaning operation may be forcibly performed by stopping at the nearest floor. The cleaning operation control outputs a door open command, and when the completion of door opening is detected, issues a startup command to the fan 133 for a certain period of time, or issues an output command to the ultraviolet irradiation unit 134 for a certain period of time while the door is closed. conduct. When the control is performed, the elevator car 110 that is being controlled may be excluded from the service target or the service may be suspended in response to a service request from another floor. Conditions for ending cleaning operation include elapse of a certain period of time after an output command.
The clean operation command unit 118b outputs a control command to the corresponding output equipment 130 under the control of the clean operation control unit 118a.

The car interior cleaning operation shall have one or more modes. For example, it is assumed that there are three modes: in-car cleaning operation (strong), in-car cleaning operation (medium), and in-car cleaning operation (weak). Clean operation (weak) shall be given the lowest priority. However, in order to periodically perform the cleaning operation in the car, it is desirable that there are one or more modes that define the conditions for periodic start-up.

For example, the car interior cleaning operation (strong) is activated when a person with an abnormal body temperature is detected and sneezing or coughing. The content of the control is to exclude the elevator car 110 from the service target, close the door of the car 111, and operate the ultraviolet irradiation unit 134. FIG. The termination condition of the operation is, for example, completion of the operation for 2 minutes.
Since the in-car cleaning operation (strong) is the mode with the highest priority among the in-car cleaning operations, the activation condition was set when it was assumed that the environment inside the car had deteriorated significantly. Furthermore, in order to perform the control immediately and without fail for the specified time, the car is forcibly stopped at the nearest floor and the car 111 is excluded from the service object for 2 minutes.

For example, the inside of car cleaning operation (middle) is triggered when sneezing or coughing is detected, and after a certain period of time has passed after the service request is completed. The content of the control is to open the door of and operate the fan 133 . The termination condition of the operation is, for example, completion of the operation for one minute.
Since the car cleaning operation (medium) is a mode that takes precedence over the car cleaning operation (low), the start condition is assumed to be that the environment inside the car is deteriorating, and the control is always performed for the specified time. For this reason, the car 111 is excluded from service objects for one minute.

For example, the car interior cleaning operation (weak) is activated by opening the door of the car 111 and operating the fan 133 when the period of time set by the regular cleaning timer has elapsed and the service request has been completed and a certain period of time has elapsed. The content of control is to Here, the periodic cleaning timer is a timer that measures, for example, one hour, and is reset when the car interior cleaning operation (weak) ends. The termination condition of the operation is the completion of the operation for one minute or the occurrence of a service request.
Car cleaning operation (weak) is activated periodically, so the activation condition is the passage of a certain period of time. The operation shall be continued until the

In the above description of the car cleaning operation (strong) and the car cleaning operation (medium), detection of sneezing or coughing is included in the activation conditions, but as described later, sneezing, coughing, loud voice, and vocalization are included. The activation condition may be a case where at least one of the above is detected.
