no. 1 Embodiment ）
[0020] figure 1 It is a block diagram showing the configuration of the elevator door control device according to the first embodiment. In addition, D1 and D2 in the figure are subtractors.
[0021] Such as figure 1 As shown, the door control device of this embodiment includes: elevator control device 10, door driving motor 11, pulse encoder (PG) 12, switch mode output unit 13, speed detector 14, speed controller 15, current control device 16, power converter 17, and current detector 18.
[0022] The elevator control device 10 controls the entire elevator including door control, and here, outputs a door opening and closing command to the opening and closing pattern output unit 13 .
[0023] The door drive motor 11 is provided on a door of a car (hereinafter referred to as a car door) not shown, and the car door 1 is opened and closed by driving the drive motor 11 . In addition, a door (hereinafter, referred to as a landing door) provided at a landing not shown in the figure...
no. 2 Embodiment ）
[0044] Next, a second embodiment will be described.
[0045] In the second embodiment, in addition to the configuration of the above-mentioned first embodiment, the disturbance torque at the time of door closing is estimated from the disturbance torque at the time of door opening, and this is reflected in the setting of the torque limiter.
[0046] Figure 4 It is a block diagram showing the configuration of the elevator door control device according to the second embodiment. In addition, for the above-mentioned first embodiment figure 1 The parts with the same structure are given the same symbols, and their explanations are omitted.
[0047] Apart from figure 1 In addition to the structure, a disturbance torque estimation unit 23 is also provided. In the second embodiment, the disturbance torque estimating unit 23 has a function of estimating the disturbance torque at the time of door closing from the traveling torque when the car door 1 is opened at the arrival floor.

no. 3 Embodiment ）
[0061] Next, a third embodiment will be described.
[0062] In the third embodiment, in addition to the configuration of the first embodiment described above, the disturbance torque is estimated from the start of closing the door until the value of the torque limiter is switched, and is reflected in the setting of the torque limiter.
[0063] device structure and Figure 4 Likewise, so here use Figure 6 Be explained.
[0064] Figure 6 It is a flowchart showing the processing operation of the elevator door control device in the third embodiment.
[0065] When the car door 1 is closing, the disturbance torque estimating unit 23 estimates the disturbance torque for a predetermined period from the start of the door closing. The predetermined period from the start of closing the door is the period from the start of closing the door until switching the value of the torque limiter 21, specifically, as figure 2 Shown is the period from closing the door to the end of accelerati...
