When it is determined that a mass of a plurality of users is detected at the landing 8, the operation of the door closing button 612 in the in-car operation panel 61 is invalidated for a predetermined time.

<Elevator Operation Using the Elevator Control Device According to the First Embodiment>
Next, operation | movement of the elevator 1 by this embodiment is demonstrated with reference to the flowchart of FIG. FIG. 2 shows a process executed by the elevator control device 10 when the elevator 1 operates.

  First, during normal operation of the elevator 1 (S1), a work time zone (for example, 8am to 9am) that is preset in the elevator control device 10 and is expected to increase the number of users of the elevator 1 has arrived. Is monitored (S2). When the attendance time zone arrives (“YES” in S2), it is monitored whether or not the car 6 has landed at the landing 8 on the first floor and opened (S3). When the car 6 reaches the landing 8 on the first floor and opens the door ("YES" in S3), users in the car 6 that are acquired from the in-car camera device 62 at predetermined time intervals by the information acquisition unit 11 Whether or not the number of persons is equal to or less than a preset threshold value L is determined by the usage status determination unit 12 (S4). Here, the threshold value L is a value set according to the maximum capacity of the car 6 in order to drive efficiently by leaving the car 6 after a certain number of people get on the car. In the present embodiment, it is assumed that the maximum capacity of the car 6 is “12 people”, and the threshold L is set to “6 people”, which is 50% of the maximum capacity.

  When the number of users in the car 6 exceeds the threshold value L ("YES" in S4) as a result of the judgment by the use status judging unit 12, normal operation is continued (S5) and the car 6 is used. When the user operates the door closing button 612 or a predetermined time elapses, the car 6 is closed and departs toward the destination floor operated by the user.

  In step S4, as shown in FIG. 3, when it is determined that the number of users in the car 6 is two or less than the threshold L (“NO” in S4), the information acquisition unit 11 further stops It is determined whether or not a mass of a plurality of users has been detected at the hall 8 by the camera device 82 (S6). Whether or not a mass of a plurality of users is detected at the landing 8 is determined, for example, by whether or not a plurality of users each have a center position of the head within a predetermined distance from other users. .

  Here, as shown in FIG. 3, when information indicating that a group of five users has been detected at the landing 8 is acquired (“YES” in S6), the cars of the plurality of users are displayed. In order to wait for boarding to No. 6, the operation of the door closing button 612 is invalidated and the door open state is extended. While the operation of the door closing button 612 in the car 6 is disabled, the car in-car speaker 63 informs the user in the car 6 that it is waiting for another user to ride. The announcement information is output, and the announcement information for prompting the user to quickly get on the car 6 is outputted from the hall speaker 83 to the group user or the like at the hall 8 (S7). Then, when a predetermined time (for example, 20 seconds) set in advance as a sufficient time for boarding the group user or the like has elapsed (“YES” in S8), the operation returns to the normal operation, and the operation of the door closing button 612 is effective. Return to the state (S5).

  After the operation of the door closing button 612 is invalidated and until a predetermined time elapses (“NO” in S8), a plurality of users get into the car 6 that is open, so that the car When the number of users in 6 reaches 8 and it is detected that the threshold value “6” is exceeded (“YES” in S4), the operation returns to normal operation, and the door closing button 612 is enabled. Return (S5).

  In step S6, when information indicating that a mass of a plurality of users has been detected is not acquired at the landing 8 ("NO" in S6), the routine returns to normal operation (S5), and the inside of the car 6 When the door closing button 612 is operated by a user or a predetermined time elapses, the car 6 closes and departs toward the destination floor operated by the user.

  The processes of steps S3 to S8 described above are repeated during the work hours ("NO" in S9). When the work hours are over ("YES" in S9), the process returns to step S2, and the elevator user is It is monitored whether the next time zone that is expected to increase, for example, the lunch time zone or the work time zone has arrived.

  According to the first embodiment described above, it is possible to use a small number of people by leaving a certain number of people on the floor where boarding is concentrated in a time zone where the number of elevator users is expected to increase. Thus, it is possible to improve the driving efficiency of the elevator by leaving the car in a state where the passenger is on board and waiting for the next group car to arrive by a large number of group users.

<< Second Embodiment >>
<Configuration of Elevator System Using Elevator Control Device According to Second Embodiment>
In the elevator system 20 according to the second embodiment of the present invention, as shown in FIG. 4, a plurality of elevators 1 </ b> A, 1 </ b> B, 1 </ b> C having the same configuration as the elevator 1 described in the first embodiment are installed in a building, The elevator control devices 10A to 10C of the plurality of elevators 1A to 1C are connected to each other.

  Each of the operation control units 13A to 13C of the elevator control devices 10A to 10C is in a state where the own elevator can currently respond to a new hall call (not busy state), or is responding to a call that has already been registered and is newly It is determined at a predetermined time interval whether it is in a state where it is impossible to respond to a call at a landing (busy state), and the determination result is transmitted to other elevator control devices as driving state information. In addition, the operation control units 13A to 13C were acquired from other elevators when the car 6 landed on the first floor hall 8 and opened the door in a time zone in which many users were set in advance. Based on the driving state information, it is determined whether there is another elevator that can respond to the hall call on the floor. As a result of the determination, when it is determined that there is another elevator that can respond, the normal operation is continued, and when it is determined that there is no other elevator that can respond, the landing is performed and the door is opened as in the first embodiment. When a predetermined number of users get into the car 6 and a mass of a plurality of users is detected at the landing 8, the operation of the door closing button 612 in the car operation panel 61 of the own elevator is performed. Disable for a specified time.

<Operation of Elevator System Using Elevator Control Device According to Second Embodiment>
Processing executed in each of the elevator control devices 10A to 10C of the elevators 1A to 1C used in the elevator system 20 according to the present embodiment will be described with reference to the flowchart of FIG. In each of the elevator control apparatuses 10A to 10C, the processing in steps S1 to S3 is executed in the same manner as in the first embodiment, and it is monitored whether the car has landed on the first floor and opened. Here, a case where the elevator car 6B of the elevator 1B has landed on the first floor and opened the door will be described.

  When the car 6B reaches the landing 8 on the first floor and opens the door (“YES” in S3), the elevator 1A is based on the driving state information acquired from the other elevator control devices 10A and 10C by the information acquisition unit 11. Alternatively, it is determined whether or not any of 1C is in a not busy state in which a response to the hall call at hall 8 on the first floor is possible (S10). If it is determined that one of the elevators 1A, 1C is not busy ("YES" in S10), the process proceeds to step S5 and normal operation is continued. When the normal operation is continued, the door closing button 612 is operated by the user in the car 6B, or the car 6 is closed by a predetermined time, and the user operates the door 6 Depart for the destination floor.

  After the car 6 departs from the first floor, as shown in FIG. 6, an announcement is made to inform the group users, etc., at the hall 8 that other elevators can respond and to prompt the hall call operation. The information “The next elevator is coming. Please press the hall button” is output from the hall speaker 83. When a hall call operation is performed on the hall operation panel 81 by a group user or the like, the elevator car 6A or 6C that can respond responds to the hall 8 and opens.

  If it is determined in step S10 that the elevators 1A and 1C are both busy and cannot respond to the hall call ("NO" in S10), as in the first embodiment, steps S4 to S8 are performed. Processing is executed. In other words, when it is detected that a number of users equal to or less than the threshold value L are in the car 6, if a group of a plurality of users at the landing 8 is detected, the doors in the car 6 are detected. The operation of the close button 612 is disabled for a predetermined time.

  According to the second embodiment described above, in a building where a plurality of elevators are installed, when there is an elevator that can respond to other floors where boarding is concentrated in a time zone where the number of elevator users is expected to increase. Even if there are a plurality of users at the hall, the other elevators can respond immediately, so the door closing button in the car remains active and normal operation is performed. And when there are no other elevators that can respond, users should start after a certain number of people get in, rather than leaving in a state where a small number of users are in the open car. The operating efficiency of the elevator can be improved without impairing the convenience of the vehicle as much as possible.

  Generally, since there are many group users on the standard floor (mainly the first floor) where the entrance of the building is located, by switching the validity / invalidity of the door closing button as described above only on the standard floor, The operation efficiency of the elevator can be improved.

  In the above-described embodiment, a case where the number of users in the car 6 that has landed on the first floor and opened is analyzed by analyzing the image information captured by the in-car camera device 62. As described above, the number of users in the car 6 may be detected based on the detection information of the load detecting device installed in the car 6.

  Further, in the above-described embodiment, a case has been described in which a group of a plurality of users at the landing 8 on the first floor is detected by analyzing imaging information captured by the landing camera device 82. Alternatively, a human sensor may be installed at the entrance of the hall 8 and the mass of users at the hall 8 may be detected based on detection information of the human sensor.

  In the embodiment described above, when the operation of the door closing button 612 in the car 6 is disabled, the user in the car 6 is notified at the timing when the door closing button 612 is operated by the user. You may make it output the announcement information for alert | reporting that it is in the boarding state of another user from the speaker 63 in a cage | basket | car.
