Car position determining device and car position determining method

Abstract

The present invention relates to a car position determination device and a car position determination method. In the past, the air pressure data was erroneously corrected when the floor where the passenger car stopped due to a power failure, elevator inspection, etc. changed, and the floor at which the passenger car stopped could not be obtained using the corrected air pressure data. The measurement data generation unit (14) included in the car position determination device (12) determines that the passenger car (1) is stopped, based on the acceleration generated in the moving direction of the car door (2) for each floor, Find the number of times the car door (2) is opened and closed. In the floor data generation unit (15), the air pressure data of the floor data table (15a) and the arrival of the passenger car (1) are stored in association with the stored air pressure data and the number of times of opening and closing of the car door (2) for each floor. When the air pressure data output from the air pressure sensor (5) at the reference floor is different, the air pressure data stored in the floor data table (15a) is corrected based on the air pressure data output from the air pressure sensor (5).

Description

technical field [0001] The invention relates to a car position determination device and a car position determination method. Background technique [0002] The remote monitoring system for measuring abnormalities of elevators uses the information of the control device that controls the elevators to measure abnormalities in car position and speed, closing failures, etc., and notifies the elevator control center and maintenance personnel of the measured status. In this remote monitoring system, the floor where the passenger car of the elevator is located is specified by acquiring the position information of the passenger car output from the control device for controlling the elevator. [0003] However, in the case of an elevator that cannot use the information of the elevator control device, for example, a relay type elevator that is an old elevator, data cannot be collected. Therefore, in the remote monitoring system that remotely monitors the operation of the elevator, it is...

Problems solved by technology

[0003] However, in the case of an elevator that cannot use the information of the elevator control device, such as a relay type elevator that is an old elevator, the data cannot be collected

Therefore, in the remote monitoring system that remotely monitors the operation of the elevator, it is impossible to collect control information including the floor where the passenger car stops, and it is impossible to grasp the current position of the passenger car.
