Problems solved by technology

However, when there is a user in the car, the acceleration of the car changes due to the actions of the user in the car, and the acceleration signal reflecting the operating status of the car may be hidden.
Therefore, correct air pressure data can only be corrected when there is no user in the car, and as a result, the accuracy of determining the position of the car will be affected.

Embodiment Construction

[0018] Embodiments of the present invention will be described below using the drawings.

[0019] figure 1 It is an overall configuration diagram of the elevator monitoring system of this embodiment. like figure 1 As shown, the elevator monitoring system of the present embodiment includes a sensor module 1 , a control module 2 , a communication line 3 , a monitoring server 4 , a monitoring device 5 , and a terminal device 6 . Furthermore, the car position specifying device 7 is constituted by the sensor module 1 and the control module 2 .

[0020] Although not shown in the figure, the elevator includes a car, a counterweight, a main rope, and a hoist. The main sling hangs the car and counterweight and is driven by the winch, whereby the car and counterweight move in the hoistway.

[0021] In addition, the sensor module 1 is installed on an upper portion of an elevator car, and has a magnetic sensor 8 and an air pressure sensor 9 . The air pressure sensor 9 outputs the dete...

Abstract

The invention provides a car position determination device and a car position determination method. A car position determination device is provided with a control module that determines the position of a car on the basis of a detection signal from a sensor module provided in the car of an elevator, the sensor module having a magnetic sensor and an air pressure sensor. The control module corrects the barometric sensor and estimates the stop position of the car using the corrected sensor value of the barometric sensor when detecting the opening / closing operation of the door when the car is stopped on the basis of the detection signal of the magnetic sensor.

Description

technical field [0001] The invention relates to an elevator car position determination device and a car position determination method. Background technique [0002] The remote monitoring system that measures the abnormality of the elevator generally uses the information of the control device that controls the elevator to measure the abnormality of the position or speed of the car, the closure failure, etc., and notifies the monitoring center of the elevator of the measurement status or performs maintenance of workers. However, some elevators may not be able to use the information of the control device of the elevator. In this case, a method of detecting the position of the car based on information obtained from an external sensor has been proposed. [0003] In addition, a technique of using an air pressure sensor as the external sensor has also been proposed. For example, in the technique described in Patent Document 1, a floor data table is generated in advance by associa...
