[0028] [Overall structure of the elevator device]

[0029] figure 1 It is a schematic diagram showing an example of the overall configuration of the elevator apparatus according to the first embodiment of the present invention. figure 1 In FIG. 2 , the structure of the module for detecting the failure of the position detector 7 for determining the position of the car 1 is also shown. figure 1 Herein, it is assumed that the lifting direction of the car 1 of the elevator device 100 is the X direction, the direction perpendicular to the X direction is the Y direction, and the direction perpendicular to the X direction and the Y direction is the Z direction.

[0030] The elevator apparatus 100 is configured such that a car 1 (elevating body) is connected to a counterweight 3 via main ropes 2 in an elevator hoistway 4 provided in a building 101, and the car 1 can be raised and lowered along guide rails not shown. A machine room (not shown) is provided above the hoistway 4 (outsid...

[0079] Image 6 It is a schematic diagram showing an example of the overall configuration of an elevator apparatus according to a second embodiment. Image 6 The elevator apparatus 100A has a control unit 12A. The control unit 12A does not have the floor height measurement circuit 13 ( figure 1 ), the car position detection circuit 15 is also used as the floor height measurement circuit 13.

[0080] The car position detection circuit 15 generates an altimeter similarly to the floor height measurement circuit 13 using the signal output from the rotation detector 11 according to the rotation of the sheave 9a. That is, the car 1 is made to run at a low speed from the bottom floor (fo...

[0087] Figure 7 It is a schematic diagram showing an example of the overall configuration of an elevator apparatus according to a third embodiment. Figure 7 The elevator apparatus 100B has the control part 12B. The control unit 12B does not have the rotation detector 11 and the car position detection circuit 15 ( figure 1 ), the floor height measurement circuit 13 doubles as the car position detection circuit 15.

[0088] The floor height measurement circuit 13 receives a pulse signal output from the pulse generator 6 according to the rotation of the motor 5M during normal operation (during high-speed operation). Then, the floor height m...

Abstract

The present invention provides an elevator apparatus and a program capable of detecting troubles of a position detector without setting a restriction on an installation position of a position detection component. The elevator apparatus includes a car position detection circuit that detects movement amount of the car from the departure floor based on a signal output from a signal generator that outputs signals corresponding to rotation of a rotating body; a position detection component correspondingly arranged in a lifting hoistway; a position detector arranged on the car to detect the positiondetection component; a height storage unit in which relationships between the floors and the height from a reference floor are stored; and a floor detection circuit that detects, based on the movement amount of the car from the departure floor and the relationships between the floors and the height from a reference floor; and a failure determination circuit that obtains detection results of the floor detection circuit and the position detector, and based on the number of floors through which the car moves and the number of position detection components detected by the position detector, determines failure of the position detector.

Description

technical field [0001] The invention relates to an elevator device and program for lifting and lowering a car in a hoistway, in particular to a technique for detecting failure of a position detector installed on the car. Background technique [0002] The car of the elevator device is equipped with a position detector that detects the door area that passengers can enter and exit and the absolute position of the car. Conventionally, an elevator control device described in Patent Document 1 is known as a device for detecting a failure of a position detector. [0003] The control device for an elevator described in Patent Document 1 includes: a counting unit that counts pulses synchronized with the rotational speed of a motor that drives a car; computing unit. In addition, the control device of the elevator has a position detection unit, which is installed in the car, and outputs the position indicating the current position of the car based on the positions of the detection bo...
