  Here, the priority is numeric data in which 1 is the highest priority value. About this priority, you may decide a priority simply in order with many stress passengers, and may make a certain floor raise a priority irrespective of the number of stress passengers.

  FIG. 5 is a diagram showing an operation flow of the group management unit 20 according to Embodiment 1 of the present invention. The specific operation of the present invention will be described below with reference to FIG.

  First, when a passenger appears on the hall, the passenger stress detection means 11 in the passenger stress detection unit 10 is connected to at least one of various sensors (imaging sensor, voice sensor, infrared sensor) installed on each floor. The passenger is detected based on the detection signal of the equivalent) and the stress state of the passenger is monitored. More specifically, the passenger stress detection means 11 detects a state where the passenger has been waiting for a long time at the landing and feels stress (a state showing a sign of stress) by the following method.

(Detection method 1) Facial expression detection is performed by a camera (imaging sensor) to detect an expression in which a passenger feels stress (a moody expression or an angry expression).
(Detection method 2) Motion detection by a camera is performed to detect a passenger's stress release behavior (stepping) and the like.
(Detection method 3) Voice detection by a voice detection device (voice sensor) is performed to detect passengers' screams, tongue strikes, and the like.
(Detection method 4) The temperature of a passenger is detected by an infrared sensor or the like, and a rise in passenger's body temperature is detected.

  When the passenger stress is detected as a quantitative electric signal by any one or combination of these detection methods, the passenger stress detection means 11 feels the stress based on the detection signal. The number of persons is counted and transmitted to the group management unit 20 as the number of stress persons via the stress person number transmitting means 12.

  And in step S501 of FIG. 5, when the passenger stress determination means 22 in the group management part 20 receives the stress person number information transmitted from the passenger stress detection part 10 via the stress person number reception means 21, Proceed to the next Step S502. On the other hand, when the stress number information has not been received, the series of processing ends.

  When the processing proceeds to step S502, the passenger stress determination unit 22 records the number of stress passengers included in the received stress number information in the passenger stress status data in the stress data storage unit 23.

  In this recording, the passenger stress determination means 22 updates the passenger stress situation data corresponding to the floor where the passenger stress detection unit 10 that is the transmission source of the stress number information is installed.

  After the update of the passenger stress situation data in the stress data storage unit 23 is finished, in step S503, the passenger stress determination means 22 analyzes the number of stress passengers for each floor recorded in the stress data storage unit 23, Priorities are determined for each floor and passenger stress status data is updated.

  As to how to determine the priority, as described above, the floor having the largest number of stress passengers may be set to have the highest priority, or may be set based on another guideline. For example, it is possible to assign a priority in consideration of an elapsed time after detecting a passenger appearing at a landing. Thus, by considering the elapsed time, the stress state of the passenger can be quantitatively evaluated more accurately and reflected in an appropriate operation service.

  Thereafter, in step S504, the passenger stress determination means 22 analyzes the number of stress passengers included in the passenger stress status data in the stress data storage unit 23, and the number of detected passengers is equal to or higher than a predetermined number. And the elevator and the priority corresponding to the floor are notified to the elevator vehicle allocation control means 24. Although the extraction condition at this time is set to a predetermined number of people or more, the numerical value can be changed depending on the actual situation.

  Finally, in step S505, the elevator dispatching control unit 24 controls the elevator so as to preferentially service the higher-priority floor based on the floor and priority information notified from the passenger stress determination unit 22. . At this time, the elevator vehicle allocation control means 24 controls the elevator so as to preferentially service the floor that can be serviced earlier for the floor having the same priority.

  Furthermore, when there is a floor where the number of stress passengers is not zero, the elevator vehicle allocation control means 24 makes the elevator door opening and closing operations on all floors faster than the normal speed, or It is also possible to control the elevator so that the time from the completion of opening to the door closing operation is shorter than the normal time.

  As described above, according to the first embodiment, the stress state of the passengers at the landing is quantitatively grasped, the number of people in the stress state is obtained for each floor, and the elevator is assigned according to the priority assignment according to the number of people. The operation is controlled. As a result, it is possible to realize an elevator control device that can execute an appropriate operation service in consideration of a passenger who feels stress.
