The invention discloses an elevator system and control method for improving elevator safety. The elevator system comprises an elevator body, a detection assembly and safety tongs, a car of the elevator body is slidably connected with an elevator shaft, a traction machine is rotatably connected with the car and a counterweight through a pull rope, a speed limiter is mounted on one side of a car body, a first photoelectric sensor and a tachometer wheel are arranged on one side of the car body, multiple temperature sensors and multiple smoke sensors of the detection assembly are mounted on different floors of the elevator shaft, and temperature and smoke information of the different floors can be obtained. When the fire requirement is met, a control system drives the traction machine to lowerthe car body at a constant speed and sends distance information of a safety floor to a circuit board, the circuit board calculates the moving distance and triggers the safety tongs to carry out braking, the car body can stop on the safety floor, people can escape, and therefore the safety of people in a fire disaster can be guaranteed.

    本发明公开了一种提高电梯安全性的电梯系统及其控制方法,包括电梯主体、检测组件和安全钳,电梯主体的轿厢和电梯竖井滑动连接,曳引机通过拉绳与轿厢和对重转动连接,限速器安装在轿厢本体的一侧,轿厢本体的一侧有第一光电传感器和测速轮,检测组件的多个温度传感器和多个烟雾传感器安装在电梯竖井的不同楼层,可以获取不同楼层的温度和烟雾信息,当达到火灾要求时,控制系统驱动曳引机匀速下放轿厢本体并发送安全楼层的距离信息给电路板,电路板计算出移动的距离,触发安全钳进行制动,使得轿厢本体可以停在安全楼层,使得人员可以逃生,从而可以保障在火灾时人员的安全。
