Problems solved by technology

[0010] However, according to Patent Document 1, in order to calculate the position of the sign board, it is necessary to prepare the contour curve in advance, and it is also necessary to perform functional processing of the output. Therefore, it is estimated that the calculation amount of the calculation device will become very large.

Abstract

The position detecting device detects edge of a detected object with precision the same as that of a photoelectric detector without using a photoelectric detector. The position detecting device of elevator comprises: a metal detected object (1) arranged in a hoist trunk of an elevator car; a vortex detector (2) arranged in the elevator car, running through a position opposite to the detected object and at least arranged with two detectors (2a, 2b) staggered in hoist direction of the elevator car. The position detecting device of elevator further comprises: a detecting unit detecting output value before and after change of output value of electric coupling when the detector passes through the position opposite to the detected object; a standard setting unit setting standard output value according to output value of a detector (2a) detected by the detecting unit; a position detecting unit outputting position detecting signal according to the compared result between output value of another detector (2b) and the standard output value.

Description

Technical field [0001] The invention relates to a position detection device of an elevator and elevator equipment having the position detection device of the elevator. Background technique [0002] The position detection device for detecting the position of the elevator car is configured to detect the position of the detected device when the detector installed on the elevator car moves to a position opposite to the detected device installed in the hoistway, and Output detection signal. For example, when adjusting the positions of the floor surface of the elevator car and the floor surface of the elevator lobby, the above-mentioned position detection device is an indispensable device. [0003] As the above-mentioned position detectors, detectors such as photoelectric detectors, electrostatic capacity type detectors, and eddy current type detectors are known. Among them, the photoelectric detector can accurately detect the object to be detected from its characteristics, but because...
