Abstract

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.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator system for improving elevator safety and a control method thereof. Background technique [0002] Elevator is a kind of lifting tool commonly used in modern times. It is widely used in residential buildings and shopping malls. It mainly adopts a power system to pull the elevator car up and down, and controls it with an electronic circuit board. [0003] In the prior art, when a fire breaks out, the higher temperature and open flame may damage the circuit board, causing the elevator to lose control and start the brake calipers to be stuck at a certain height, making it impossible for people in the elevator to get out, and even due to a fire. The thick smoke that produces can be suffocated, which will greatly threaten people's life safety. Contents of the invention [0004] The object of the present invention is to provide an elevator system and its control method f...
