Problems solved by technology

The resistance value of the motor rotor, which is directly related to the torque characteristics, changes with this temperature change, thereby becoming prone to setting errors
Therefore, when the torque characteristics of the door motor fluctuate with such temperature changes, there is a discrepancy between the actual opening and closing movement speed of the door panel (hereinafter referred to as the actual opening and closing movement speed) and the opening and closing movement speed command (moving speed pattern). The problem of declining followability

Embodiment approach 1

[0025] figure 1 It is a block diagram showing a part of the car door device according to Embodiment 1 of the present invention.

[0026] exist figure 1 Here, the car door device 1 opens and closes a doorway (not shown) of a car. Also, the car door device 1 has a door hanger plate (beam) 2, a door guide rail frame 3, a pair of winding wheels 4A, 4B, a door motor 5, a drive bar body (rope) 6, and a plurality of door hanger wheels 7A. -7D, a pair of door hangers (door hooks) 8A, 8B, a pair of car door panels 9A, 9B, and a pair of connecting members 10A, 10B.

[0027] The door hanger plate 2 is provided on the upper part of the car doorway of the car. The door guide rail frame 3 is horizontally installed on the door hanger plate 2 along the length direction of the door hanger plate 2 . A pair of winding wheels 4A and 4B are respectively provided at one end and the other end of the door hanger plate 2 in the longitudinal direction. The door motor 5 is provided at one end porti...

Embodiment approach 2

[0136] In Embodiment 1, the floor data storage part 120 has memorize|stored the door weight J measured in advance. On the other hand, in Embodiment 2, the floor data storage part 120 stores the door weight J identified (identified) successively by the door weight identification part 122 based on the control history data of existing door opening and closing. That is, the door weight J in Embodiment 2 is updated sequentially by the door weight recognition unit 122 and the door weight J stored in the door weight recognition unit 122 .

[0137] Figure 5 It is a block diagram schematically showing a part of the elevator door control device according to Embodiment 2 of the present invention. in addition, Figure 5 is the same as that of Embodiment 1 image 3 The corresponding figures are omitted, and the magnetic flux control unit 112 , the input coordinate conversion unit 113 , and the output coordinate conversion unit 115 in Embodiment 1 are omitted from illustration.

Abstract

In a door control device of an elevator, a magnetic flux observation section (117) estimates the secondary magnetic flux of a door motor (5) using a primary voltage command values Vd*, Vq* and an arithmetic expression based on the mathematical model of the door motor (5). A magnetic flux control section (112) and a speed control section (119) generate respective current commands using the secondary magnetic flux of the door motor (5) calculated by the magnetic flux observation section (117).

Description

technical field [0001] The invention relates to an elevator door control device, which is used for controlling the movement of the elevator door device. Background technique [0002] In a conventional door control device for an elevator, when the drive control of the door motor is performed, the target torque of the motor is calculated assuming that the set value of the motor constant parameter of the door motor coincides with the actual value. However, the door device of an elevator may be used regardless of the indoor / outdoor environment, and there is a difference in the utilization rate between when it is crowded and in other cases. Therefore, relatively large temperature changes occur in the door motor depending on the installation environment and / or usage conditions. The resistance value of the rotor of the motor, which is directly related to the torque characteristic, changes with such a temperature change, whereby a setting error easily occurs. Therefore, when the t...
