Elevator position detection device and level control method

Abstract

The invention provides an elevator position detection device. The elevator position detection device comprises a detection device and an operator, wherein the detection device and the operator communicate with each other; the detection device comprises a triaxial inertial sensor, a data processor and an interface circuit; the triaxial inertial sensor comprises a triaxial accelerometer and a triaxial gyroscope; the triaxial accelerometer is used for detecting the accelerated speed of a lift car when an elevator is operated, and the triaxial gyroscope is used for detecting the angular speed of the lift car when the elevator is operated; the data processor is connected with the triaxial inertial sensor and the interface circuit; the data processor is used for receiving elevator operation three-dimensional data of the triaxial inertial sensor, calculating to obtain the current absolute position and the operating speed of the lift car of the elevator and transmitting to a main controller ofthe elevator through the interface circuit; and the interface circuit is used for communication between the data processor and the main controller of the elevator as well as between the data processor and the operator. According to the elevator position detection device, the elevator level is precise, and the installation and debugging are simple and convenient.

Description

technical field [0001] The invention relates to the technical field of elevator detection, in particular to an elevator position detection device. Background technique [0002] In recent years, with the accelerated pace of urbanization, more and more high-rise buildings have sprung up. As a vertical means of transportation, the application of elevators is gradually increasing with the increase of high-rise buildings, so the comfort, safety and reliability of elevators are more and more valued by everyone. [0003] The comfort, safety, and reliability of elevators are mainly reflected in the control of acceleration and deceleration when the elevator is running, and the accuracy and reliability of leveling. At present, elevators generally rely on the cooperation of leveling switches and detection magnetic strips or partitions and detection devices such as magnetic scales and grating scales to achieve leveling, but the above-mentioned leveling devices still have the following ...

AI Technical Summary

Problems solved by technology

When debugging the elevator, it is necessary to adjust the position of the detection magnetic strip or the partition layer by layer to adjust the better leveling position. The installation and debugging steps are cumbersome, the efficiency is extremely low, and a lot of time and manpower are wasted.

At the same time, the magnetic scale and grating scale need to be installed vertically from the top of the elevator guide rail and tightened to the bottom of the elevator guide rail during installation. Not only is the installation more cumbersome, but there is also the possibility of the magnetic scale and grating scale breaking after years of application.

[0005] Second, the detection magnetic strip of the magnetic induction leveling switch and the magnetic grid of the magnetic scale may demagnetize, resulting in a change in the detection distance or a loss of position, which will cause inaccurate or impossible leveling of the elevator

[0006] Third, the transmitter and receiver of the photoelectric leveling switch and the plug and grating of the grating scale have the disadvantages of being not resistant to oil and dust.

The environment in the elevator shaft is harsh. If the transmitting device or receiving device of the photoelectric switch and the plug or grating of the grating scale are covered by opaque objects such as oil, dust, etc., they will lose their function, resulting in the failure of the elevator to level and the elevator to shut down people, etc. Fault
