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.

[0031] First, a configuration example and an operation example of the elevator 50 according to the first embodiment of the present invention will be described.

[0032] figure 1 It is a schematic diagram showing a structural example of elevator 50 according to the first embodiment.

[0033] The elevator 50 is provided with: a passenger car 1, a hoist 6 for raising and lowering the passenger car 1, a balance weight 7 for reducing the load when the passenger car 1 is raised and lowered, and a balance weight 7 for avoiding the passenger car 1 The contact pulley 8, the main rope 9 connecting the passenger car 1 and the balance weight.

[0034] The passenger car 1 is equipped with a car door 2, a door opening and closing device 3, a three-axis acceleration sensor 4, and an air pressure sensor 5.

[0035] The car door 2 is installed in the passenger car 1, and opens and closes if the passenger car 1 stops at the target floor.

[0036] The door opening and closing device 3 controls the openin...

Abstract

The invention relates to a car position determination device and a car position determination method. In the prior art, when the floor where a passenger car stops changes due to power failure, elevator maintenance and the like, air pressure data can be corrected mistakenly, and the floor where the passenger car stops cannot be obtained by using the corrected air pressure data. When it is determined that the passenger car (1) is stopped, a measurement data generation unit (14) provided in the car position identification device (12) finds the number of times the car door (2) is opened and closedfor each floor on the basis of the acceleration generated in the movement direction of the car door (2). When a floor data generation unit (15) stores, for each floor, air pressure data of a floor data table (15a) in which stored air pressure data and the number of opening / closing times of a car door (2) are associated with each other, and air pressure data output from an air pressure sensor (5)when a passenger car (1) reaches a reference floor, the air pressure data is different from each other. The air pressure data stored in the floor data table (15a) is corrected on the basis of the airpressure data output from the air pressure sensor (5).

Description

Technical field [0001] The invention relates to a car position determining device and a car position determining method. Background technique [0002] The remote monitoring system that measures the abnormality of the elevator uses the information of the control device that controls the elevator, measures the abnormality of the car position, speed, and shutdown failure, etc., and notifies the elevator control center and maintenance personnel of the measured state. In this remote monitoring system, by acquiring the position information of the passenger car output from the control device that controls the elevator, the floor where the passenger car of the elevator is located is determined. [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-style elevator, data cannot be collected. Therefore, in a remote monitoring system that remotely monitors the operation of an elevator, it is imp...
