Safety driving system for prevention of falling and falling of elevator car

摘要

The present invention relates to a safe traveling apparatus for preventing an elevator car curb and a collision, and more particularly, it relates to a safety navigation apparatus for avoiding an elevator car curvature and a collapse of an elevator car by calculating the running speed of the elevator car through an encoder installed in the governor, The motor driving unit, which outputs the error signal, drives the motor in accordance with the predetermined deceleration slope to prevent the elevator car from falling or falling. The governor 20 installed in the elevator machine room and rotating in accordance with the elevator car speed An encoder 22 installed at a predetermined rotation axis of the governor 20 to generate a pulse signal corresponding to the rotation of the governor 20, and a control unit 22 for calculating the pulse speed of the elevator car by calculating the pulse signal output from the encoder 22 A traveling speed of the elevator car calculated from the speed calculating section 24, A speed comparing section 26 for comparing the read reference running speed data from the data storing section 28 and outputting an error signal when it is determined that the overspeeding running speed is equal to the reference running speed data which is a reference for judging the overspeed running of the elevator car, A setting data storage unit 32 for storing a preset deceleration slope and an error signal output from the speed comparison unit 26. The control unit 30 controls the setting data storage unit 32, And a motor drive unit (36) for reading the set deceleration slope and drivingly controlling the motor (38) based on the deceleration slope.
