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.

Embodiment 2

[0090] Next, a second embodiment of the elevator position detection device to which the present invention is applied will be described with reference to the drawings. In addition, in this embodiment, the description of the same function and structure as that of the first embodiment 1 is omitted.

[0091] like Figure 8 As shown, in this embodiment, the detectors 2a, 2b are arranged side by side on a straight line perpendicular to the moving direction 3, and with respect to the detected surface of the detected object 1, there is a predetermined gap (pitch) between them. mode is set in the horizontal direction. In addition, the detectors 2a and 2b move in the horizontal direction while maintaining a relative positional relationship by being connected by a rigid body. That is, in this embodiment, the shape of the edge of the object 1 and the arrangement of the detectors 2a and 2b are different from those in the first embodiment.

[0099] A third embodiment of the elevator position detection device to which the present invention is applied will be described below with reference to the drawings. Figure 13 It is a perspective view showing the positional relationship between the detector and the object to be detected in the elevator position detection device of the present embodiment. Figure 14 It is a block diagram showing the configuration of an arithmetic unit that receives an output signal from a detector in the elevator position detection device of this embodiment and performs arithmetic processing. Figure 15 to Figure 18 The relationship between the position of the detector and the output in the position detection device of the elevator of this embodiment is shown. Figure 19 is true Figure 14 A flow chart illustrating the operation of the computing device. In addition, the description of the same function and structure as the first embodiment is omitted.

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 present invention relates to an elevator position detection device and an elevator installation having the elevator position detection device. Background technique [0002] The position detecting device for detecting the position of the elevator car is configured to detect the position of the detected device when the detector arranged on the elevator car moves to a position opposite to the detected device arranged 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 hall, the above-mentioned position detection device is an indispensable device. [0003] As the above-mentioned position detector, detectors such as a photoelectric detector, an electrostatic capacity type detector, and an eddy current type detector are known. Among them, the photoelectric detector can accurately detect the object to be detected due to its characteristics,...
