Elevator car monitoring device and monitoring method

Abstract

The invention provides an elevator car monitoring device and a monitoring method, which can be used for the leveling control of the elevator card in a high-precision manner by using the simple structure without requiring the arrangement of a plurality of shielding boards and a plurality of corresponding detection parts, which are disposed on the same floor. The elevator car monitoring device comprises a unit (16) used for acquiring elevator car position information by using an elevator car position detection device (14) of an coder (10) used for a speed regulator, a unit (16)used for acquiring floor height value information of every floor, a unit (18) used for detecting a jump between an elevator car floor and an elevator hall floor according to the elevator car position information and the floor height value information, a unit (17) used for transmitting a leveling control correction signal to an elevator control device 13, and a unit (19) used for storing a determining value. When the calculated jump exceeds the determining value, the leveling control correction signal can be transmitted to the elevator control device (13).

Description

Technical field [0001] The invention relates to a monitoring device and a monitoring method of an elevator car. Background technique [0002] Generally, an elevator installs a rotary encoder for a motor on a rotary drive shaft of a motor that moves a car up and down, and uses output pulses from the rotary encoder for a motor to detect the travel distance of the car. [0003] In addition, in order to stop so that there is no step difference between the car floor and the elevator hall floor, a shielding plate that determines the stopping position of the car is provided for each floor of each floor, and a position detection unit that detects the shielding plate is installed in the car. Compartment. [0004] Moreover, the shielding plate is set so that if the position detection unit stops at the center position of the vertical direction of the shielding plate, the step difference between the car floor and the hall floor becomes zero, and when the car stops, the position detection unit d...
