Problems solved by technology

[0010] In the prior art mentioned above, detection and correction of the error and stop error between the ground of each floor and the floor surface of the elevator car are not taken into account. For example, the amount of expansion and contraction of the main sling leads to an increase in the floor stop error of the elevator

Embodiment Construction

[0049] The following pairs figure 1 The configuration and operation of an elevator system according to an embodiment of the present invention shown will be described.

[0050] The elevator car 1 on which passengers ride is connected to the counterweight 3 through the main rope 2 , and the main rope 2 is wound and suspended on the sheave 4 and the diverting pulley 5 . The sheave 4 is driven by a drive device (motor) 6 , and the drive device 6 receives power for driving through a power source 7 and a power conversion device 8 . In addition, the speed of the driving device 6, the position of the elevator car corresponding to the speed and the moving distance in the vertical direction adopt the pulse generator 9 set on the driving device 6, and the control device (system controller) 10 controls the following The pulses generated in the pulse generator 9 are counted according to the rotation of the motor, and various control quantities are calculated and detected. Here, since the...

Abstract

The invention provides a lift equipped with a stop control device, comprising a lift car (1) for moving between a plurality of floors in lifting channel, a weight counterbalance (3), a main sling (2)for moving the lift car and the weight counterbalance, a rope pulley (4) for transmitting driving force to the main sling (2), a driving device (6) for driving the rope pulley (4) and a control device(10) for controlling the driving device (6); wherein, the position of the lift car (1) is detected excluding detecting the stretching tensor of the main sling (2); according to the difference of theposition of the preset stop floor and the lift car floor, the rest running distance of the preset floor is resolved, and according to the resolved value, the driving device (6) is controlled. The invention is able to improve the high travel route and the floor stop precision of the express lift.

Description

technical field [0001] The invention relates to an elevator control device, especially suitable for an elevator that can still maintain good parking accuracy under the condition of a high stroke. Background technique [0002] As a prior art, for example, a technical solution is disclosed in Patent Document 1, which detects the position of the elevator car in the building. The computer counts the output pulses of the pulse generator connected to the motor for driving the elevator car and the pulses formed by the waveform shaping of the output voltage of the AC speed generator to estimate the vertical velocity of the moving elevator car. Location. [0003] In addition, for example, a technical solution is disclosed in Patent Document 2, which calculates the remaining travel distance based on the difference between the current position of the car and the value of the floor height table of the stop destination floor in order to improve the operating efficiency, and The acceler...
